    Erta Ale volcano lies along the on-shore Red Sea Rift (northern Afar, Ethiopia), separating the Nubia and Danakil plates. Erta Ale has a NNW-SSE elongated caldera, with a subvertical rim scarp, hosting a lava lake. Structural field work was aimed at defining the deformation pattern around the caldera. The caldera consists of along-rim and across-rim structures, resulting from local and regional (maximum extension ˜NE-SW) stress fields, respectively. These structures cross-cut each other at high angles, suggesting that the two stress fields remain distinct, each prevailing during rifting or caldera collapse. The local along-rim extensional fractures are gravity-driven structures that formed due to the retreat of the caldera wall after collapse, and are confined to the region of caldera subsidence. The across-rim structures are mainly located to the N and S of the caldera, where they form rift zones each accommodating a similar amount of extension (˜6.3 m), but displaying different trends and extension directions. Analogue models of interacting fractures are consistent with the Southern Rift being representative of the regional fault kinematics, while the Northern Rift is a local perturbation, resulting from the interaction between two right-stepping rift segments along the Erta Ale Range.

    The Afar Depression, Ethiopia, offers unique opportunities to study the transition from continental rifting to oceanic spreading because the process is occurring onland. Using traveltime tomography and data from a temporary seismic deployment, we describe the first regional study of uppermost mantle P-wave velocities (VPn). We find two separate low VPn zones (as low as 7.2 km s-1) beneath regions of localized thinned crust in northern Afar, indicating the existence of high temperatures and, potentially, partial melt. The zones are beneath and off-axis from, contemporary crustal magma intrusions in active magmatic segments, the Dabbahu-Manda-Hararo and Erta'Ale segments. This suggests that these intrusions can be fed by off-axis delivery of melt in the uppermost mantle and that discrete areas of mantle upwelling and partial melting, thought to characterize segmentation of the uppermost mantle at seafloor spreading centres, are initiated during the final stages of break-up.

    A cross-sectional study was conducted in the pastoral region of Afar, in eastern and central Ethiopia, to determine the distribution of brucellosis in small ruminants. Between December 2005 and June 2006, 1,568 serum samples were taken: 563 samples from sheep and 1,005 from goats. One hundred and forty-seven of these (9.4%) tested positive using the Rose Bengal plate test (RBPT), and 76 (4.8%) also tested positive by the complement fixation test (CFT). Brucellosis was detected in all five administrative zones of the region. The difference in prevalence (P) among the zones was not statistically significant (P > 0.05). The seroprevalence of Brucella infection was found to be 5.8% (n = 58) in goats and 3.2% (n = 18) in sheep. A prevalence rate of 5.3% was observed in adult animals and 1.6% in younger sheep and goats. Caprine species (chi2 = 5.56) and adult goats and sheep (chi2 = 4.84) were found to be at higher risk of Brucella infection (P 0.05). The study showed that small-ruminant brucellosis is a widely distributed disease in Afar. The authors recommend the implementation of well-organised disease control and prevention methods to mitigate the economic losses and public health hazard caused by the disease.

    Invasion of non-native species is among the most critical threats to natural ecosystems and economies world-wide. Mesquite (which includes some 45 species) is an invasive deciduous tree which is known to have an array of negative impacts on ecosystems and rural livelihoods in arid and semi-arid regions around the world, dominating millions of hectares of land in Asia, Africa, Australia and the Americas. In Ethiopia, Prosopis juliflora (the only reported mesquite) is the most pervasive plant invader, threatening local livelihoods and the country's unique biodiversity. Due to its rapid spread and persistence, P. juliflora has been ranked as one of the leading threats to traditional land use, exceeded only by drought and conflict. This project utilized NASA's Earth Observing System (EOS) data and species distribution modeling to map current infestations of P. juliflora in the Afar region of northeastern Ethiopia, and forecast its suitable habitat across the entire country. This project provided a time and cost-effective strategy for conducting risk assessments of invasive mesquite and subsequent monitoring and mitigation efforts by land managers and local communities.

    Full Text Available Data on genotypic diversity of Mycobacterium tuberculosis complex (MTBC is important to understand its epidemiology, human adaptation, clinical phenotypes, and drug resistance. This study aimed to characterize MTBC clinical isolates circulating in a predominantly pastoralist area in Ethiopia, a country where tuberculosis is the second leading cause of mortality. Culture of sputum samples collected from a total of 325 pulmonary TB suspects was done to isolate MTBC. Spoligotyping was used to characterize 105 isolates from culture positive slopes and the result was compared with an international database. Forty-four spoligotype patterns were observed to correspond to 35 shared-types (SITs containing 96 isolates and 9 orphan patterns; 27 SITs containing 83 isolates matched a preexisting shared-type in the database, whereas 8 SITs (n=13 isolates were newly created. A total of 19 SITs containing 80 isolates were clustered within this study (overall clustering of 76.19%. Three dominant lineages (T, CAS, and Manu accounted for 76.19% of the isolates. SIT149/T3-ETH was one of the two most dominant sublineages. Unlike previous reports, we show that Manu lineage strains not only constitute a dominant lineage, but are also associated with HIV infection in Afar region of Ethiopia. The high level of clustering suggests the presence of recent transmission that should be further studied using additional genotyping markers.

    Accelerated deformation after major dike intrusion events such the 1975-1985 Krafla events in Iceland and the 1978 Asal-Ghoubbet events in Afar have been interpreted as the result of stress relaxation in a viscoelastic lithospheric mantle and/or continued magma injection. Separating these contributions, estimating mantle viscosity and quantifying the interaction with long-term stretching has however proven difficult in the absence of geodetic measurements early on after the main dike intrusion. In September 2005, a 60km-long dike intrusion took place at the Dabbahu rift, Afar, Ethiopia, at the boundary between the Nubian and Arabian (Danakil) plates. Since this major event, 8 new intrusions have affected the central and southern parts of the 2005 dike. In order to measure post-diking deformation, we installed 19 continuous stations in the near-field of the 2005 intrusion and 20 survey sites in the mid- and far-field. Time series from continuous GPS stations outside of volcanoes show a combination of discrete diking events and quasi-constant velocity displacements. Continuous GPS stations on volcanoes show non-linear behaviour related to the feeding of shallow magma chambers. Survey GPS sites in the far-field (up to 150km from the rift) show current extension rates twice as fast as the secular divergence rate between Nubia and Arabia. We present the GPS results and, with some constraints from seismicity, propose a preliminary model that accounts for the combination of dike intrusions and viscoelastic stress relaxation in the upper mantle below Afar.

    We used correlative models with species occurrence points, Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation indices, and topo-climatic predictors to map the current distribution and potential habitat of invasive Prosopis juliflora in Afar, Ethiopia. Time-series of MODIS Enhanced Vegetation Indices (EVI) and Normalized Difference Vegetation Indices (NDVI) with 250 m2 spatial resolution were selected as remote sensing predictors for mapping distributions, while WorldClim bioclimatic products and generated topographic variables from the Shuttle Radar Topography Mission product (SRTM) were used to predict potential infestations. We ran Maxent models using non-correlated variables and the 143 species-occurrence points. Maxent generated probability surfaces were converted into binary maps using the 10-percentile logistic threshold values. Performances of models were evaluated using area under the receiver-operating characteristic (ROC) curve (AUC). Our results indicate that the extent of P. juliflora invasion is approximately 3,605 km2 in the Afar region (AUC = 0.94), while the potential habitat for future infestations is 5,024 km2 (AUC = 0.95). Our analyses demonstrate that time-series of MODIS vegetation indices and species occurrence points can be used with Maxent modeling software to map the current distribution of P. juliflora, while topo-climatic variables are good predictors of potential habitat in Ethiopia. Our results can quantify current and future infestations, and inform management and policy decisions for containing P. juliflora. Our methods can also be replicated for managing invasive species in other East African countries.

    In September 2005, a 60km-long dike intrusion took place at the Dabbahu rift, Afar, Ethiopia, at the boundary between the Nubian and Danakil plates. Since this major event, 12 new intrusions have affected the central and southern parts of the 2005 dike. Time series from continuous GPS stations outside of volcanoes show a combination of discrete diking events and quasi constant velocity displacement at rates up to 10 times faster than the secular divergence rate between Nubia and Arabia. Survey GPS sites in the far-field show rates twice as fast as the secular Nubia/Arabia divergence. Similar observations after the 1975-1985 Krafla events in Iceland and the 1978 Asal-Ghoubbet events in Afar have been interpreted as the result of stress relaxation in a viscoelastic lithospheric mantle and/or continued magma injection. Nooner et al. (submitted) showed that horizontal GPS displacements are well explained by the relaxation, in a viscoelastic upper mantle, of the stresses imparted by the dike intrusions. The best fit is obtained for a 13.2km-thick crust overlying a mantle with a viscosity of 5.2x10^18Pa.s. We improve upon this approach with a model accounting for dike intrusions, viscoelastic stress relaxation in a power-law rheology upper mantle, laterally varying crustal thicknesses, and pressure changes in magma reservoirs. Preliminary results indicate that 3-dimensional velocity field from GPS and InSAR requires a combination of viscoelastic relaxation and magma transport at depth.

    Full Text Available Abstract Background Afar pastoralists live in the northeast of Ethiopia, confined to the most arid part of the country, where there is least access to educational, health and other social services. Tuberculosis (TB is one of the major public health problems in Afar region. Lack of knowledge about TB could affect the health-seeking behaviour of patients and sustain the transmission of the disease within the community. In this study, we assessed the knowledge and perception of apparently healthy individuals about pulmonary tuberculosis (PTB in pastoral communities of Afar. Methods Between March and May 2009, a community-based cross-sectional questionnaire survey involving 818 randomly selected healthy individuals was conducted in pastoral communities of Afar region. Moreover, two focus group discussions (FGDs, one with men and one with women, were conducted in each of the study area to supplement the quantitative study. Results The majority (95.6% of the interviewees reported that they have heard about PTB (known locally as "Labadore". However, the participants associated the cause of PTB with exposure to cold air (45.9%, starvation (38%, dust (21.8% or smoking/chewing Khat (Catha edulis (16.4%. The discussants also suggested these same factors as the cause of PTB. All the discussants and the majority (74.3% of the interviewees reported that persistent cough as the main symptom of PTB. About 87.7% of the interviewees and all the discussants suggested that PTB is treatable with modern drugs. All the discussants and the majority (95% of the interviewees mentioned that the disease can be transmitted from a patient to another person. Socio-cultural practices, e.g. sharing cups (87.6%, and house type (59.8% were suggested as risk factors for exposure to PTB in the study areas, while shortage of food (69.7% and chewing khat (53.8% were mentioned as factors favouring disease development. Almost all discussants and a considerable number (20.4% of the

    Full Text Available Livestock production is a key income source in eastern Africa, and 80% of the total agricultural land is used for livestock herding. Hence, ecological and socio-economically sustainable rangeland management is crucial. Our study aimed at selecting operational economic, environmental and social sustainability indicators for three main pastoral (P, agro-pastoral (AP, and landless intensive (LI small scale livestock production systems for use in sustainability assessment in Ethiopia. Quantitative and qualitative data were collected through grey literature and semi-structured interviews, assessing livestock and feed resources, production technology, land tenure, financial and gender issues. Our results suggested that feed shortages (FS are directly related to grazing pressure (G and inversely related to grass recovery rates (R. According to our indicators, AP was the most sustainable while P and LI were only conditionally sustainable production systems. 93% of 82 interviewees claimed that private land ownership was the best land tenure incentive for efficient rangeland management. Farmers perceived Prosopis juliflora expansion, sporadic rainfall, and disease infestation as the most significant causes for decreasing livestock productivity. Landless intensive farmers had the highest equality in income distribution (Gini Index: GI = 0.4, followed by P and AP (each with a GI = 0.5. Neither educational background nor income seemed to determine grazing species conservation efforts. We claimed that sustainability indicators are valuable tools to highlight shortcomings and strengths of the three main livestock production systems and help with future livestock management in Ethiopia. Selecting suitable indicators, however, is crucial as data requirements and availability can vary across livestock systems.

    Full Text Available The threats posed by invasive plants span ecosystems and economies worldwide. Local knowledge of biological invasions has proven beneficial for invasive species research, but to date no work has integrated this knowledge with species distribution modeling for invasion risk assessments. In this study, we integrated pastoral knowledge with Maxent modeling to assess the suitable habitat and potential impacts of invasive Cryptostegia grandiflora Robx. Ex R.Br. (rubber vine in Ethiopia's Afar region. We conducted focus groups with seven villages across the Amibara and Awash-Fentale districts. Pastoral knowledge revealed the growing threat of rubber vine, which to date has received limited attention in Ethiopia, and whose presence in Afar was previously unknown to our team. Rubber vine occurrence points were collected in the field with pastoralists and processed in Maxent with MODIS-derived vegetation indices, topographic data, and anthropogenic variables. We tested model fit using a jackknife procedure and validated the final model with an independent occurrence data set collected through participatory mapping activities with pastoralists. A Multivariate Environmental Similarity Surface analysis revealed areas with novel environmental conditions for future targeted surveys. Model performance was evaluated using area under the receiver-operating characteristic curve (AUC and showed good fit across the jackknife models (average AUC = 0.80 and the final model (test AUC = 0.96. Our results reveal the growing threat rubber vine poses to Afar, with suitable habitat extending downstream of its current known location in the middle Awash River basin. Local pastoral knowledge provided important context for its rapid expansion due to acute changes in seasonality and habitat alteration, in addition to threats posed to numerous endemic tree species that provide critical provisioning ecosystem services. This work demonstrates the utility of integrating local

    Bottenberg, Helen Carrie

    This work utilizes the Four-Dimensional Plates (4DPlates) software, and Differential Interferometric Synthetic Aperture Radar (DInSAR) to examine plate-scale, regional-scale and local-scale kinematics of the Afro-Arabian Rift System with emphasis on the Afar Depression in Ethiopia. First, the 4DPlates is used to restore the Red Sea, the Gulf of Aden, the Afar Depression and the Main Ethiopian Rift to development of a new model that adopts two poles of rotation for Arabia. Second, the 4DPlates is used to model regional-scale and local-scale kinematics within the Afar Depression. Most plate reconstruction models of the Afro-Arabian Rift System relies on considering the Afar Depression as a typical rift-rift-rift triple junction where the Arabian, Somali and Nubian (African) plates are separating by the Red Sea, the Gulf of Aden and the Main Ethiopian Rift suggesting the presence of "sharp and rigid" plate boundaries. However, at the regional-scale the Afar kinematics are more complex due to stepping of the Red Sea propagator and the Gulf of Aden propagator onto Afar as well as the presence of the Danakil, Ali Sabieh and East Central Block "micro-plates". This study incorporates the motion of these micro-plates into the regional-scale model and defined the plate boundary between the Arabian and the African plates within Afar as likely a diffused zone of extensional strain within the East Central Block. Third, DInSAR technology is used to create ascending and descending differential interferograms from the Envisat Advanced Synthetic Aperture Radar (ASAR) C-Band data for the East Central Block to image active crustal deformation related to extensional tectonics and volcanism. Results of the DInSAR study indicate no strong strain localization but rather a diffused pattern of deformation across the entire East Central Block.

    In March 2007 41 seismic stations were deployed in north east Ethiopia. These stations recorded until October 2009, whereupon the array was condensed to 13 stations. Here we show estimates of crustal structure derived from receiver functions and upper mantle velocity structure, derived from tomography and shear-wave splitting using the first 2.5 years of data. Bulk crustal structure has been determined by H-k stacking receiver functions. Crustal Thickness varies from ~45km on the rift margins to ~16km beneath the northeastern Afar stations. Estimates of Vp/Vs show normal continental crust values (1.7-1.8) on the rift margins, and very high values (2.0-2.2) in Afar, similar to results for the Main Ethiopian Rift (MER). This supports ideas of high levels of melt in the crust beneath the Ethiopian Rift. Additionally, we use a common conversion point migration technique to obtain high resolution images of crustal structure beneath the region. Both techniques show a linear region of thin crust (~16km) trending north-south, the same trend as the Red Sea rift. SKS-wave splitting results show a general north east-south west fast direction in the MER, systematically rotating to a more north-south fast direction towards the Red Sea. Additionally, stations close to the recent Dabbahu diking episode show sharp lateral changes over small lateral distances (40° over Danakil microplate. Outside of these focused regions the velocities are relatively fast. Below ~250km the anomaly broadens to cover most of the Afar region with only the rift margins remaining fast. At transition zone depths little anomaly is seen beneath Afar, but some low velocities remain present beneath the MER. These studies suggest that in northern Ethiopia the Red Sea rift is dominant. The presence of thin crust beneath northern Afar suggests that the Red Sea rift is creating oceanic like crust in this region. The lack of deep mantle low velocity anomalies beneath Afar suggest that a typical narrow conduit

The overall animal prevalence of TB in small ruminants was 0.5% (95% CI: 0.2%–0.7% at ≥4 mm and 3.8% (95% CI: 3%–4.7% at cutoff ≥2 mm. The herd prevalence was 20% (95% CI: 12–28% and 47% (95% CI: 37–56% at ≥4 mm and ≥2 mm cut-off points, respectively. The overall animal prevalence of Mycobacterium avium complex infection was 2.8% (95% CI: 2.1–3.5% and 6.8% (95% CI: 5.8–7.9% at ≥4 mm and ≥2 mm cut-off points, respectively. Mycobacteriological culture and molecular characterization of isolates from tissue lesions of tuberculin reactor goats resulted in isolation of Mycobacterium tuberculosis (SIT149 and non-tuberculosis mycobacteria as causative agents of tuberculosis and tuberculosis-like diseases in goats, respectively. The isolation of Mycobacterium tuberculosis in goat suggests a potential transmission of the causative agent from human and warrants further investigation in the role of small ruminants in epidemiology of human tuberculosis in the region.

    Shallow dike intrusions may be accompanied by fault slip above the dikes, a superposition which complicates seismic and geodetic data analyses. The diverse volcano-tectonic and low-frequency local earthquakes accompanying the 2005-2010 large-volume dike intrusions in the Dabbahu-Manda Hararo rift (Afar), some with fault displacements of up to 3 m at the surface, provide an opportunity to examine the relations among the earthquakes, dike intrusions, and surface ruptures. We apply the frequency index (FI) method to characterize the spectra of swarm earthquakes from six of the dikes. These earthquakes often have broad spectra with multiple peaks, making the usual peak frequency classification method unreliable. Our results show a general bimodal character with high FI earthquakes associated with deeper dikes (top > 3 km subsurface) and low FI earthquakes associated with shallow dikes, indicating that shallow dikes result in earthquakes with more low-frequency content and larger-amplitude surface waves. Low FI earthquakes are more common during dike emplacement, suggesting that interactions between the dike and faults may lead to lower FI. Taken together, likely source processes for low FI earthquakes are shallow hypocenters (<3 km) possibly with surface rupture, slow rupture velocities, and interactions with dike fluids. Strong site effects also heavily influence the earthquake spectral content. Additionally, our results suggest a continuum of spectral responses, implying either that impulsive volcano-tectonic earthquakes and the unusual, emergent earthquakes have similar source processes or that simple spectral analyses, such as FI, cannot distinguish different source processes.

    Few reconstructions of the Afar rift combine plate kinematics with analyses of the rift basin evolution. The Afar rift is a highly-extended region of continental to transitional oceanic crust lying at the junction of the Red Sea, Gulf of Aden and Ethiopian rifts. Here, we present a new Afar reconstruction taking into account plate kinematics, crustal thinning and magmatic construction. We use a regional plate reconstruction incorporating Nubia, Arabia, Somalia and Danakil to constrain the regional-scale extension and subsidence of the rift and relative movement of Danakil. The plate model is temporally and spatially well constrained at the onset of rifting (ca. 20 Ma) and from sea-floor spreading anomalies in the Red Sea (ca. 6 Ma-present) and Gulf of Aden (ca. 10 Ma-present). The Red Sea pre-rift fit is constrained by piercing points along the Red Sea margins (Sultan et al. 1993). We model the Late Oligocene to present-day evolution of the Afar crust by volume balance using a crustal model based on published topographic and depth-to-Moho interpretations as well as volume estimates of extrusive and sedimentary rocks. Errors stemming from plate boundary uncertainties are small in relation to the reconstructed volume. We partition Afar magmatism into pre-extensional and syn-extensional volumes. From thermal modeling and flexural considerations we infer that the regional-scale subsidence of the Afar depression was virtually complete by Mid Pliocene time. Our model supports the interpretation that the escarpments bounding the Afar Depression achieved nearly their present height (ca. 3 km) by the Late Miocene. Erosional considerations suggest the Late Miocene escarpments were steeper than they are today. Our model does not support the interpretation found in the paleo-anthropological literature that Late Miocene and Pliocene vertical movements were sufficiently large (ca. 2 km) to cause small fault blocks such as Hadar to migrate through climatic temperature zones

  19. Examining the Causes of Low-frequency Hybrid Earthquakes During Dike Intrusions in the Afar Rift, Ethiopia

    2014-12-01

    Between 2005 and 2012, there were 14 large dike intrusions into the Dabbahu rift segment in the Afar rift, Ethiopia. Swarms of earthquakes with local magnitudes between 1.45events found 173 earthquakes with more low-frequency content and longer codas than expected for typical volcano-tectonic events. These unusual earthquakes were classified as low-frequency hybrid events based on peak frequency and percent of energy below 2 Hz. Previous studies in other volcanic regions have found similar events, which has led to debate about what causes these events and how best to classify them. Explanations for hybrid events include both source and path effects, though the results from previous work and this study suggest that the Afar hybrids are largely a result of path effects based on high attenuation (Q ~ 200) and azimuthal dependence of spectral content. However, large (~3m) surface displacements on short faults indicate that unusual source processes, such as slow rupture times, may also be a factor in these hybrid events. The aims of this study are to distinguish between path and source effects, to characterize the source processes of these events, and to explore the relation between hybrid and normal tectonic events in the region - are the differences in the source or only in the path? For closely located earthquakes, an Empirical Green's Function approach is a great method to isolate the source-time function. Spectral analysis of the source-time function can be used to provide insights into the rupture time, stress drop, and scaling relations of the earthquakes. These results will be used to further refine earthquake classifications and determine if there are any defining characteristics of the classes that associate them with specific faulting processes, such as surface ruptures, that occur during diking events.

    The existence of narrow axial volcanic zones of mid-oceanic ridges testifies of the underlying concentration of both melt distribution and tectonic strain. As a result of repeated diking and faulting, axial volcanic zones therefore represent a spectacular topographic expression of plate divergence. However, the submarine location of oceanic ridges makes it difficult to constrain the interplay between tectonic and magmatic processes in time and space. In this study, we use the Dabbahu-Manda Hararo (DMH) magmatic rift segment (Afar, Ethiopia) to provide quantitative constraints on the response of tectonic processes to variations in magma supply at divergent plate boundaries. The DMH magmatic rift segment is considered an analogue of an oceanic ridge, exhibiting a fault pattern, extension rate and topographic relief comparable to intermediate- to slow-spreading ridges. Here, we focus on the northern and central parts of DMH rift, where we present quantitative slip rates for the past 40 kyr for major and minor normal fault scarps in the vicinity of a recent (September 2005) dike intrusion. The data obtained show that the axial valley topography has been created by enhanced slip rates that occurred during periods of limited volcanism, suggestive of reduced magmatic activity, probably in association with changes in strain distribution in the crust. Our results indicate that the development of the axial valley topography has been regulated by the lifetimes of the magma reservoirs and their spatial distribution along the segment, and thus to the magmatic cycles of replenishment/differentiation (<100 kyr). Our findings are also consistent with magma-induced deformation in magma-rich rift segments. The record of two tectonic events of metric vertical amplitude on the fault that accommodated the most part of surface displacement during the 2005 dike intrusion suggests that the latter type of intrusion occurs roughly every 10 kyr in the northern part of the DMH segment.

    Dyking and faulting at mid-oceanic ridges are concentrated in narrow axial volcanic zones due to focussing of both melt distribution and tectonic strain along the plate boundary. Due to the predominantly submarine location of oceanic ridges, the interplay between these processes remain poorly constrained in time and space. In this study, we use the Dabbahu-Manda Hararo (DMH) magmatic rift segment (MRS) (Afar, Ethiopia) to answers the long debated chicken-egg question about magmatic and tectonic processes in extensive context: which on comes first, and how those two processes interplay to finally form oceanic ridges? The DMH MRS is an oceanic ridge analogue and here we present quantitative slip rates on major and minor normal fault scarps for the past 40 kyr in the vicinity of a recent (September 2005) dike intrusion. Our data show that the long-term-vertical slip rates of faults that ruptured in 2005 are too low to explain the present rift topography and that the 2005 strain distribution is not the main stress accommodating mechanism in the DMH segment. Instead, we show that the axial valley topography is created by enhanced slip rates which occur only when the amount of magma available in magma reservoirs is limited, thus preventing dykes from reaching the surface. Our results suggest that development of the axial valley topography is regulated by the magma reservoir lifetime and, thus, to the magmatic cycles of replenishment/differentiation (< 100 ky). This implies that in the DMH rift system (with a magma supply typical of an intermediate spreading centre), significant topography of the axial rift valley is transient, and is expressed only when magma available in the reservoirs decreases. The absence of tilting on the rift margins over the last 200 kyr also suggests that amagmatic accommodation of extension is not required over this time period. Extension instead is accommodated by dykes injected laterally from multiple ephemeral reservoirs located along the DMH

    The state of stress in the Afar region, where the Arabian, Nubian, and Somalian plates meet, is investigated by inversion of earthquake focal mechanisms. Based on earlier studies in the region, we compiled a catalogue of 93 earthquakes, M > 4, with focal mechanisms, spanning the time period from 1969 to present. From this data set we select three clusters suitable for inversion: one along the EW trending Gulf of Aden and Tadjoura rift, one in central Afar, and one on the western margin of the Afar depression. Using the grid-search based inversion of Lund and Slunga (1999), we assess how the choice of fault plane from the nodal planes affect the results and include known fault data where possible. The resulting stress states show an overall normal faulting stress regime. This especially pronounced in the cluster on the western margin of the Afar depression, whereas the southern two clusters have more oblique stress states with significant strike-slip components. The estimated directions of the minimum principal stress vary from NE on the Danakil -Somalia plate boundary to an approximate EW direction at the western margin of the Afar depression. Although the data is scarce, we discuss the temporal consistency of the stress field through the studied time period. The broad zone of active extensional deformation at the Afar Depression, a triple junction where the Red Sea, the Gulf of Aden and the Main Ethiopian rift systems meet, constitutes a complicated tectonic region and we discuss our results in this context. We also compare the stress estimates to available deformation data in the region.

    The present study was conducted to assess the seroprevalence of peste des petits ruminants (PPR) in sheep and goats in Awash Fentale district, Afar, Ethiopia. Small ruminants in the district had poor herd immunity at the first visit and succumb to the disease then after. The seroprevalence during the time of an outbreak was much higher compared with the initial levels: 7.3% and 42.6% in sheep and goats, respectively. The higher seroprevalence figure in goats was suggestive of their relative susceptibility to PPR compared with sheep.

    Full Text Available A total of 206 urine samples collected from Hassoba Elementary schoolchildren, Afar, Ethiopia, a low Schistosoma haematobium endemic setting, was diagnosed to evaluate the performance of CCA strip using double references, urine filtration technique and urinalysis dipstick (Combur 10 Test® that detect schistosome eggs and blood in urine, respectively. The former was used as a gold standard reference method. Sensitivity, specificity, positive and negative predictive values for the CCA were 52%, 63.8%, 56.7% and 59% respectively, with reference to urine filtration technique whereas these parameters were 50.4%, 62.4%, 55.6% and 57.5% respectively, with reference to Combur 10 Test®. 47 S. haematobium egg-positive children were found negative by CCA strip while 38 egg-negative children were found positive by CCA strip. Moreover, among the pre-tests done in duplicate, inconsistent results were also recorded. Assays were also compared with regard to the cost of equipment and reagents, speed and simplicity of use. Though CCA strip was found to be rapid and could be performed with minimal training, it was found to be expensive (US $ 4.95 per test to use it for large-scale field use even if its diagnostic value would have been satisfactory. Further development and standardization of the CCA strip are required for its applicability for field use. It is also recommended that its cost per strip should be substantially cut down if it is to be used in poor schistosomiasis endemic countries.

    A cross-sectional epidemiological study followed by vaccination and postvaccinal serum antibody assessment against Peste des Petits Ruminants (PPR) in small ruminant population of Awash Fentale District, Afar, Ethiopia, was conducted from September 2006 to June 2007 with the aim of investigating seroprevalence and post-vaccination sero-conversion rate. A total of 1239 sera collected from sheep and goats which were not vaccinated, were screened by using nucleoprotein-based competitive enzyme-linked immunosorbent assay (c-ELISA). Only 21 (1.70%) animals were found to be positive. Following the base-line seroprevalence study, small ruminants in the area were vaccinated using the attenuated homologous PPR virus (Nigeria 75/1) strain vaccine, produced at National Veterinary Institute (NVI) in Debre-Zeit, Ethiopia. A total of 1096 small ruminants were resampled from the vaccinated population fourteen days after vaccination. The postvaccination sero-conversion rate in the population was found to be 61.13%, indicating a relatively weak herd immunity. The main reason for the low sero-conversion could be the thermolabile nature of the vaccine, since no statistically significant difference was observed between small ruminants vaccinated by Veterinary Professionals and Community Animal Health Workers (CAHWs), using Chi-squared test at 95% CI (P>0.05). This signifies the need for thermostable vaccine that could potentially increase the herd immunity in addition to that being administered by CAHWs independently. The current finding indicated that CAHWs could participate in vaccination campaigns in such areas as Afar, where there are few veterinarians despite of the huge livestock populations, as means of pastoralists' livelihood.

    The threats posed by invasive plants span ecosystems and economies worldwide. Local knowledge of biological invasions has proven beneficial for invasive species research, but to date no work has integrated this knowledge with species distribution modeling for invasion risk assessments. In this study, we integrated pastoral knowledge with Maxent modeling to assess the suitable habitat and potential impacts of invasive Cryptostegia grandiflora Robx. Ex R.Br. (rubber vine) in Ethiopia’s Afar region. We conducted focus groups with seven villages across the Amibara and Awash-Fentale districts. Pastoral knowledge revealed the growing threat of rubber vine, which to date has received limited attention in Ethiopia, and whose presence in Afar was previously unknown to our team. Rubber vine occurrence points were collected in the field with pastoralists and processed in Maxent with MODIS-derived vegetation indices, topographic data, and anthropogenic variables. We tested model fit using a jackknife procedure and validated the final model with an independent occurrence data set collected through participatory mapping activities with pastoralists. A Multivariate Environmental Similarity Surface analysis revealed areas with novel environmental conditions for future targeted surveys. Model performance was evaluated using area under the receiver-operating characteristic curve (AUC) and showed good fit across the jackknife models (average AUC = 0.80) and the final model (test AUC = 0.96). Our results reveal the growing threat rubber vine poses to Afar, with suitable habitat extending downstream of its current known location in the middle Awash River basin. Local pastoral knowledge provided important context for its rapid expansion due to acute changes in seasonality and habitat alteration, in addition to threats posed to numerous endemic tree species that provide critical provisioning ecosystem services. This work demonstrates the utility of integrating local ecological

    In the Afar depression (Ethiopia), extension is organised along rift segments that morphologically resemble oceanic rifts. Segmentation results from interactions between dyke injection and volcanism, as observed during the well-documented 2005 rifting event on the Dabbahu rift segment. This tectono-volcanic crisis was observed in detail via remote sensing techniques, providing invaluable information on the present-day tectonic - magmatic interplay during a sequence of dyke intrusions. However, lack of data remains on timescales of 1 to 100 kyr, the period over which the main morphology of the rift is acquired. The Dabbahu rift segment represents an ideal natural laboratory to study the evolution of rift morphology as a response to volcanic and tectonic influences. We use cosmogenic nuclides (3He and 36Cl) to determine the ages of young (<100 kyr) lava flows and to date the initiation and movement of fault scarps, which cut the lavas. Where possible, we analysed vertical profiles along fault scarps, in an attempt to distinguish individual tectonic events that offset the scarp, estimate their amplitudes and date the recurrence intervals. These geochronological constraints, combined with major & trace element compositions, field mapping and digital mapping (Landsat, ASTER and SPOT imagery), provide valuable insights on the magmatic and tectonic history of the segment. The results show that over the last 100 ka, the northern part of the Dabbahu segment was supplied by at least two different magma reservoirs, which can be identified from their distinctive chemistries. The main reservoir is located beneath Dabbahu volcano at the northern tip of the rift segment, and has been supplied with magma for at least 72 ka. The second reservoir is located further south on the rift axis and corresponds to the current mid-segment magma chamber, which was responsible for the 2005 rifting episode. Two magmatic cycles linked to the Dabbahu magma chamber were recorded, lasting 20-30 kyr

    The study was conducted in Chifra district in Awsi-Resu zone of Afar Regional State to explore production objectives and strategies of sheep and goats in pastoral and agro-pastoral production systems. Cross-sectional survey with systematic random selection of 180 households (90 households from each production system was conducted. Descriptive statistics, t test, chi-square test, analysis of variance, and ranking method were employed in analyzing data using JMP-5 software. In pastoral production system, sheep and goat were primarily reared for household milk consumption, followed by live animal savings and income, while in agro-pastoral production system, sheep and goat are primarily reared for income, followed by household milk consumption and manure supply, as live animal savings. Overall mortality rates of sheep and goats (4 to >12 months of age) were 9 and 9.5 % in pastoral production systems while 7 and 6 % in agro-pastoral production system. Average age at first mating, kidding interval, days of mating after birth, weaning age, lactation length, litter size, slaughtering age, and marketable age of sheep and goats in pastoral production system were 7.4 months, 358 days, 29 days, 4.2 months, 3.1 months, 1.5 lambs, 7.4 months, and 14 months, respectively, while in agro-pastoral production system, they are 6.9 months, 353.3 days, 28 days, 3.2 months, 1.6 lambs, 6.4 months, and 14.5 months, respectively. It was concluded that production system-based development interventions could help to increase the productivity of sheep and goats and thereby enhance the livelihood of smallholders.

  10. The Quaternary volcanic rocks of the northern Afar Depression (northern Ethiopia): Perspectives on petrology, geochemistry, and tectonics

    2016-05-01

    The northern Afar Depression is one of the most volcano-tectonically active parts of the East African Rift system, a place where oceanic rifting may be beginning to form an incipient oceanic crust. In its center, over an area that is ∼80 km long and ∼50 km wide, there are seven major NNW-SSE-aligned shield volcanoes/volcanic edifices surrounded by compositionally distinct fissure-fed basalts. The Quaternary lavas in this area range from transitional to tholeiitic basalts, with significant across-axis variation both in mineralogy and chemistry. The variation in the contents of the major elements (TiO2, Al2O3, and Fe2O3), incompatible trace elements (Nd, Hf, Th, Ta), and the contents and ratios of the rare earth elements (REE) (e.g., (La/Yb)n = 5.3-8.9) indicate some variation in the petrogenetic processes responsible for the formation of these basalts. However, the variation in isotopic compositions of the mafic lavas is minimal (87Sr/86Sr = 0.7036-0.7041, 143Nd/144Nd = 0.51286-0.51289), which suggests only one source for all the Danakil Depression basalts. These basalts have isotope and incompatible trace element ratios that overlap with those of the Oligocene High-Ti2 flood basalts from the Ethiopian Plateau, interpreted as being derived from the last phase/tail of the Afar mantle plume source. Moreover, the Ce/Pb, Ba/U ratios indicate that the involvement of continental crust in the petrogenesis of the basaltic rocks is minimal; instead, both depth and degree of melting of the source reservoir underneath the northern Afar Depression played a major role for the production of incompatible element-enriched basalts (e.g., AleBagu Shield basalts) and the incompatible element-depleted tholeiitic basalts (e.g., Erta'Ale and Alu Shield basalts).

    A new detailed palaeomagnetic study of Tertiary volcanics, including extensive K-Ar and 40Ar/39Ar dating, helps constrain the deformation mechanisms related to the opening processes of the Afar depression (Ethiopia and Djibouti). Much of the Afar depression is bounded by 30 Myr old flood basalts and floored by the ca 2 Myr old Stratoid basalts, and evidence for pre-2 Ma deformation processes is accessible only on its borders. K-Ar and 40Ar/39Ar dating of several mineral phases from rhyolitic samples from the Ali Sabieh block shows indistinguishable ages around 20 Myr. These ages can be linked to separation of this block in relation to continental breakup. Different amounts of rotation are found to the north and south of the Holhol fault zone, which cuts across the northern part of the Ali Sabieh block. The southern domain did not record any rotation for the last 8 Myr, whereas the northern domain experienced approximately 12 +/- 9° of clockwise rotation. We propose to link this rotation to the counter-clockwise rotation observed in the Danakil block since 7 Ma. This provides new constraints on the early phases of rifting and opening of the southern Afar depression in connection with the propagation of the Aden ridge. A kinematic model of propagation and transfer of extension within southern Afar is proposed, with particular emphasis on the previously poorly-known period from 10 to 4 Ma.

    2013-01-01

    This study analyses observed and projected climatic trends over Ethiopia, through analysis of temperature and rainfall records and related meteorological fields. The observed datasets include gridded station records and reanalysis products; while projected trends are analysed from coupled model simulations drawn from the IPCC 4th Assessment. Upward trends in air temperature of + 0.03 °C year−1 and downward trends in rainfall of − 0.4 mm month−1 year−1 have been observed over Ethiopia's southwestern region in the period 1948-2006. These trends are projected to continue to 2050 according to the Geophysical Fluid Dynamics Lab model using the A1B scenario. Large scale forcing derives from the West Indian Ocean where significant warming and increased rainfall are found. Anticyclonic circulations have strengthened over northern and southern Africa, limiting moisture transport from the Gulf of Guinea and Congo. Changes in the regional Walker and Hadley circulations modulate the observed and projected climatic trends. Comparing past and future patterns, the key features spread westward from Ethiopia across the Sahel and serve as an early warning of potential impacts.

  18. Large magnitude silicic volcanism in north Afar: the Nabro Volcanic Range and Ma'alalta volcano

    Wiart, Pierre; Oppenheimer, Clive

    2005-02-01

    Much of the volcanological work carried out in north Afar (Ethiopia and Eritrea) has focused on the nature of Quaternary basaltic volcanic ranges, which have been interpreted by some as incipient oceanic ridges. However, we show here that comparable volumes of silicic magmas have been erupted in the region. In particular, the virtually undocumented Nabro Volcanic Range, which runs NNE for more than 100 km from the margin of the Danakil Depression to the Red Sea coast, has a subaerial volume of the order of 550 km3, comparable to the volume of the much better known Erta’Ale axial volcanic range. Nabro volcano itself forms part of an enigmatic double caldera structure with a neighbouring volcano, Mallahle. The twin caldera may have formed simultaneously with the eruption of between 20 and 100 km3 of ignimbrite, which is readily identified in Landsat Thematic Mapper imagery. This may have been the largest explosive eruption in north Afar, and is certain to have deposited a regionally distributed tephra layer which could in the future be located in distal sections as a stratigraphic marker. An integrated analysis of optical and synthetic aperture radar imagery, digital topographic data, field observations and limited geochemical measurements, permits here descriptions and first order inferences about the structure, stratigraphy and compositions of several major volcanoes of the Afar Triangle, and a reappraisal of their regional significance.

    Measuring displacement-length profiles along normal faults provides crucial information on fault growth processes. Here, based on satellite imagery and topography we analyze 357 normal faults distributed along the active rift of Dabbahu-Manda-Hararo (DMH), Afar, which offers a unique opportunity to investigate the influence of magmatism on fault growth processes. Our measurements reveal a large variety of slip profiles that are not consistent with elastic deformation. Their analysis contributes towards a better understanding of the lateral propagation of faults, especially when nucleation points and existence of barriers are included. Using the fault growth model of Manighetti et al. (2001), we determine the preferred direction of lateral propagation for each fault. Our results suggest that lateral propagation of faults is easier away from areas where magma has been stored for long time at crustal depth, and has thus modified the thermo-mechanical properties of the host-rock. However, these areas correspond also to areas where the initiation of fault growth appears as easiest along the rift. In combining these results with the analysis of rift width and the position of magma reservoirs along DMH rift, we show that fault growth keeps track of the magma presence and/or movement in the crust.

    Rainfed agriculture continues to be an important part of Ethiopia's livelihoods and economy. Highly variable inter-annual precipitation, however, presents a serious challenge to sustainable production and subsistence survival. An improved understanding of what drives hydroclimatic extremes and an effective prediction system may help to buffer resulting impacts through improved decision-making. Precipitation data from the National Meteorological Agency at 0.1 x 0.1 grids for 1983 - 2011 during the June-September rainy season over western Ethiopia is evaluated through a cluster analysis to investigate homogeneous regions with similar rainfall patterns for subsequent prediction of seasonal precipitation for each region. A k-means clustering method is applied with the optimal number of clusters (K) selected by the within cluster sum of square errors (WSS) metric. Homogenous regions are defined with relatively clear and smooth boundaries, low inter-cluster correlations, and high intra-cluster correlations. The precipitation prediction models are statistically based, with a seasonal total prediction for each cluster; grid-based predictions are subsequently conditioned on the cluster level prediction through regression. Prospective model predictors include large-scale ocean-land-atmospheric climate variables and local variables and conditions. These predictions will be used in economic and water management models.

    The southern Red Sea and adjacent Afar area represent an enigmatic portion of the Red Sea/Gulf of Aden basin system. Although the topographic rift shoulders of the Red Sea and Gulf of Aden can be traced through this elbow, and appear to suggest that a similar width for the zone of extension is maintained across the region, the character of the floor of the rift zone changes. The distinctive character of the southern Red Sea-Afar area results in part from a topographically elevated region, possibly associated with the Red Sea-Gulf of Aden-East African rift triple junction. In addition, however, seismic data from offshore Ethiopia suggests that the distinctive character is due a complex pattern of rifting. The central axial trough of the Red Sea decreases in depth to the south toward the strait of Bab al Mandab, suggesting that rifting is dying out southward. Farther to the west at the same latitude, a major but narrow half-graben can be seen on seismic in the Gulf of Zula, bounded to the east by a large west-dipping normal fault. This structure continues south into the Danakil Depression of the Afar area. Between these two en echelon rift trends, the Danakil Alps form a long-lived high. Seismic data from the southern Red Sea of Ethiopia show southward thinning and pinch-out of the Miocene syn-rift evaporite sequence onto the northern Danakil block. Thus, it appears that the Danakil block has largely escaped Red Sea extension and subsidence. Instead, it forms a large unextended terrain located between overlapping en echelon rift trends, and may represent an accommodation zone structure associated with offset in the rift axis of the southern Red Sea.

    We present a detailed Nubia-Arabia-Somalia (NU-AR-SOM) kinematic reconstruction based on magnetic sea floor isochrons in the Gulf of Aden and Red Sea and piercing points along the Red Sea margins. The reconstruction is combined with digital topographic and depth-to-Moho data to constrain in 4D the Late Oligocene to present-day evolution of the Afar supra-Moho crust. Opposite end-member models for crustal evolution are described. We conclude that less than 20% of the present-day Afar supra-Moho crust was constructed by magmatic processes such as diking and underplating. The reconstructions indicate that the greater percentage of crustal thinning (extension) occurred before 6.2 Ma. We model the thinning of the effective elastic lithosphere that accompanied extension, and show that the regional-scale topographic development of the Afar depression was virtually complete by Mid Pliocene time. The plate-tectonic model has paleoanthropological implications. Prior to 6.2 Ma the proximal positions of NU-SOM, AR, and the Danakil block suggest subaerial conditions prevailed between Yemen and Ethiopia. Uninhibited Africa-Eurasia faunal exchange through Afar and Arabia (corroborated by isotopic and paleontologic data) was tectonically permissible until the time of the earliest hominids. Continued stretching caused the Afar land bridge(s) to disappear during Early to Mid Pliocene time. Primitive hominid populations living within the Afar Depression became isolated from AR sometime before ~3.2 Ma. With the plateau becoming less habitable due to long-term Late Neogene cooling, hominids that remained in the Afar Depression were required to adapt to a smaller range that was effectively bounded by the already well-developed NU-SOM escarpments and the newly opened Straits of Bab el Mandeb. The combination of high quality habitat,topographic confinement, and a gradual (tectonic) reduction in range, exacerbated by potentially severe fluctuations in local climate (well documented by land

    AFAR genes play a key role in the detoxification of the carcinogen Aflatoxin B(1) (AFB(1)). In the rat, Afar1 induction can prevent AFB(1)-induced liver cancer. It has been proposed that AFAR enzymes can metabolise endogenous diketones and dialdehydes that may be cytotoxic and/or genotoxic....... Furthermore, human AFAR1 catalyses the rate limiting step in the synthesis of the neuromodulator gamma-hydroxybutyrate (GHB) and was found elevated in neurodegenerative diseases such as Alzheimer's and dementia with Lewy bodies (DLB). The human AFAR gene family maps to a genomic region in 1p36 of frequent...

    The Afar Depression is an extraordinary submerged laboratory where the crustal mechanisms involved in the active rifting process can be studied. But the crustal movements at the regional scale are complicated by being the locus of the meeting of three divergent plate boundaries: the oceanic spreading ridges of the Red Sea and the Aden Ridge and the intra-continental East-African Rift (EAR). We present here the first GPS measurements conducted in a new network in Central Afar, complementing existing networks in Eritrea, around the Manda-Harraro 2005-2010 active segment, in the Northern part of the EAR and in Djibouti. Even if InSAR data were appropriate for mapping the deformation field, the results are difficult to interpret for analyzing the regional kinematics because of the atmospheric conditions, the lack of complete data catalogue, the acquisition configuration and the small velocity variations. Therefore, our measurements in the new sites are crucial to obtain an accurate velocity field over the whole depression, and focus specifically on the spatial organization of the deformation to characterize the tripe junction. These first results show that a small part of the motion of the Somalia plate with respect to the Nubia plate or the Arabia plate (2-3 mm/yr) occurs south of the Tadjura Gulf and East of the Adda-do segment in Southern Afar. The complex kinematic pattern involves a clockwise rotation of this Southeastern part of the Afar rift and can be related to the significant seismic activity regularly recorded in the region of Jigjiga (northern Somalia-Ethiopia border). The western continuation of the Aden Ridge into Afar extends West of the Asal rift segment and does not reach the young active segment of Manda-Inakir (MI). A slow gradient of velocity is observed across the Dobi Graben and across the large systems of faults between Lake Abhe and the MI rift segment. A striking change of the velocity direction occurs in the region of Assaïta, west of Lake

    The Geba basin is one of the most food-insecure areas of the Tigray regional state in northern Ethiopia due to recurrent drought resulting from erratic distribution of rainfall. Since the beginning of the 1990s, rain-fed agriculture has been supported through small-scale irrigation schemes mainly by surface-water harvesting, but success has been limited. Hence, use of groundwater for irrigation purposes has gained considerable attention. The main purpose of this study is to assess groundwater resources in the Geba basin by means of a MODFLOW modeling approach. The model is calibrated using observed groundwater levels, yielding a clear insight into the groundwater flow systems and reserves. Results show that none of the hydrogeological formations can be considered as aquifers that can be exploited for large-scale groundwater exploitation. However, aquitards can be identified that can support small-scale groundwater abstraction for irrigation needs in regions that are either designated as groundwater discharge areas or where groundwater levels are shallow and can be tapped by hand-dug wells or shallow boreholes.

  6. The mantle transition zone beneath the Afar Depression and adjacent regions: implications for mantle plumes and hydration

    The Afar Depression and its adjacent areas are underlain by an upper mantle marked by some of the world's largest negative velocity anomalies, which are frequently attributed to the thermal influences of a lower-mantle plume. In spite of numerous studies, however, the existence of a plume beneath the area remains enigmatic, partially due to inadequate quantities of broad-band seismic data and the limited vertical resolution at the mantle transition zone (MTZ) depth of the techniques employed by previous investigations. In this study, we use an unprecedented quantity (over 14 500) of P-to-S receiver functions (RFs) recorded by 139 stations from 12 networks to image the 410 and 660 km discontinuities and map the spatial variation of the thickness of the MTZ. Non-linear stacking of the RFs under a 1-D velocity model shows robust P-to-S conversions from both discontinuities, and their apparent depths indicate the presence of an upper-mantle low-velocity zone beneath the entire study area. The Afar Depression and the northern Main Ethiopian Rift are characterized by an apparent 40-60 km depression of both MTZ discontinuities and a normal MTZ thickness. The simplest and most probable interpretation of these observations is that the apparent depressions are solely caused by velocity perturbations in the upper mantle and not by deeper processes causing temperature or hydration anomalies within the MTZ. Thickening of the MTZ on the order of 15 km beneath the southern Arabian Plate, southern Red Sea and western Gulf of Aden, which comprise the southward extension of the Afro-Arabian Dome, could reflect long-term hydration of the MTZ. A 20 km thinning of the MTZ beneath the western Ethiopian Plateau is observed and interpreted as evidence for a possible mantle plume stem originating from the lower mantle.

  7. The August 2002 earthquake sequence in north Afar: Insights into the neotectonics of the Danakil microplate

    In August 2002, there was high seismic activity in Afar concentrated at the plateau margin of the northern Ethiopian rift east of Mekele, near the western part of the Danakil microplate. The spatial and temporal distributions of this seismic activity over four weeks indicate the NNW propagation of the Gulf of Aden rift across the Afar Depression towards the western Ethiopian plateau. Fault plane solutions for six larger earthquakes from the August 2002 sequence are estimated from moment tensor inversion of local broadband waveform data. The results show only normal faulting on NNW trending and NE dipping faults, which agree with tectonics of the area and distribution of aftershocks. No strike-slip component is observed in any of our fault plane solutions or those of other workers including Harvard CMT solutions in the region. Such motion would be indicative of oblique-slip deformation between the Nubian plate and the Danakil microplate consistent with counter-clockwise rotation of the microplate. Hypocentral depths of well-constrained events are 5-7 km, which is the approximate elastic plate thickness in the Main Ethiopian rift, possibly indicating the depth to the brittle-ductile transition zone in this part of the Afar Depression. The shallowness of the depth estimates agree with the macroseismic reports available from a wide area in northern Ethiopia. Potential future shallow crustal deformation may cause significant loss of human life and damage to property in the densely populated highland region around Mekele unless measures are taken in improving building standards. The b-value for this sequence is estimated to be 0.66 using a least squares fit, while it is 0.67 ± 0.16 from a maximum-likelihood approach. This estimated b-value is low or the frequency of occurrence of relatively larger magnitude events is high indicating that it is a highly stressed region as evidenced by the recent increase of the seismicity in the area.

  8. Peace in the Clinic: Rethinking "Global Health Diplomacy" in the Somali Region of Ethiopia.

    Drawing on ethnographic research with Somalis, within aid organizations, and within health care facilities in the Somali Region of Ethiopia, this article argues that what is called "global health diplomacy," despite its origins and articulations in interstate politics, is fundamentally local and interpersonal. As evidence, I outline two very different health programs in the Somali Region of Ethiopia, and how, in each, existing animosities and political grievances were either reinforced or undermined. I argue that the provision of health care in politically insecure and post-conflict settings like the Somali Region of Ethiopia is precarious but pivotal: medical encounters have the potential to either worsen the conditions in which conflicts and crises recur, or build new interpersonal and governmental relations of trust. Effective global health diplomacy, therefore, cannot be limited to building clinics and donating medicine, but must also explicitly include building positive relationships of trust between oppositional groups within clinical spaces.

    Observation of deep structures related to break-up processes at volcanic passive margins (VPM) is often a troublesome exercise: thick pre- to syn-breakup seaward-dipping reflectors (SDR) usually mask the continent-ocean boundary and hide the syn-rift tectonic structures that accommodate crustal stretching and thinning. Some of the current challenges are about clarifying 1) if tectonic stretching fits the observed thinning and 2) what is the effect of continuous magma supply and re-thickening of the crust during extension from a rheological point of view? The Afar region in Ethiopia is an ideal natural laboratory to address those questions, as it is a highly magmatic rift that is probably close enough to breakup to present some characteristics of VPM. Moreover, the structures related to rifting since Oligocene are out-cropping, onshore and well preserved. In this contribution, we present new structural field data and lavas (U-Th/He) datings along a cross-section from the Ethiopian Plateau, through the marginal graben down to the Manda-Hararo active rift axis. We mapped continent-ward normal fault array affecting highly tilted trapp series unconformably overlain by tilted Miocene (25-7 Ma) acid series. The main extensional and necking/thinning event took place during the end of this Miocene magmatic episode. It is itself overlain by flat lying Pliocene series, including the Stratoid. Balanced cross-sections of those areas allow us to constrain a surface stretching factor of about 2.1-2.9. Those findings have the following implications: - High beta factor constrained from field observations is at odd with thinning factor of ~1.3 predicted by seismic and gravimetric studies. We propose that the continental crust in Central Afar has been re-thickened by the emplacement of underplated magma and SDR. - The deformation in Central Afar appears to be largely distributed through space and time. It has been accommodated in a 200-300 km wide strip being a diffuse incipient

    Conclusions: The rate of MDR-TB was high among suspected cases in the Oromia Region of Ethiopia. Local MDR-TB detection capacity and local epidemiology studies are essential to detect MDR-TB and guide the use of the sparse resources to optimize MDR-TB control. If TB is suspected, the presence of any of the above factors should alert Oromia Region clinicians and public health professionals to screen for MDR-TB.

    Land degradation and related processes such as gullying, flooding and sedimentation, are global phenomena. Their economic consequences however are more severe in developing countries, which lack resources for prevention and mitigation. In Ethiopia, therefore, gully erosion as a form of land degradation is a prime issue. Over the past decade, gullies have formed in the foothills of the Minizr sub-catchment in the highlands of North-Western Ethiopia. Local extension workers have reported increased gully growth rates in the past five years in the downslope foothill areas. This study answers the following questions: has the gully growth rate indeed increased over the past five years compared to historical rates? What is the mechanism behind gully formation in the study area? In addition, this study looked at three possible root causes for increased erosion rates: changing land use, an increase in the ground water level, and the implementation of soil and water conservation measures in the watershed of the study area. The merit of this study is twofold. First, it shows the applicability of a fast, accessible and accurate way to digitally represent gullies through the use of video footage and photogrammetry. Secondly, it shows the dominant processes in gully formation in the area, allowing for a justified selection of measures to halt further gully growth and rehabilitate existing gullies. Two medium and one large gully were selected for detailed analysis. All gullies were located in gently-sloped areas (0-5%), with Vertisol-dominated soils. Gully shape and volume were derived using terrestrial photogrammetry in AgiSoft PhotoScan Professional. Still frames exported from video footage served as input. Approximately 30 points per gully were sampled weekly for soil moisture content over the course of September, November, and December 2014. In addition, the sites were checked for signs of subsurface flow at the end of the rainy season and again 3 months into the dry season

    The Rift Valley in Ethiopia was investigated for geothermal exploitation by the United Nations because it has Quaternary volcanoes which often indicate possible geothermal power generation. Preparations for the project are still being made, and the chemical analysis of hot springs is being conducted. The Rift Valley has high temperature springs and potential mineral deposits. The Danakil basin in Ethiopia which is included in the Northern Afar, has several active volcanoes made up of basalt deposits and has active hot springs. The East Africa Rift Valley, the Red Sea Rift Valley, and the Afar area are also areas suitable for investigation. Seven maps are included.

    Full Text Available HIV prevalence varies between 0.9 and 6.5% in Ethiopia's eleven regions. Little has been published examining the reasons for this variation.We evaluated the relationship between HIV prevalence by region and a range of risk factors in the 2005 and 2011 Ethiopian Demographic Health Surveys. Pearson's correlation was used to assess the relationship between HIV prevalence and each variable.There was a strong association between HIV prevalence and three markers of sexual risk: mean lifetime number of partners (men: r = 0.87; P < 0.001; women: r = 0.60; P = 0.05; reporting sex with a non-married, non-cohabiting partner (men: r = 0.92; P < 0.001, women r = 0.93; P < 0.001; and premarital sex. Condom usage and HIV testing were positively associated with HIV prevalence, while the prevalence of circumcision, polygamy, age at sexual debut and male migration were not associated with HIV prevalence.Variation in sexual behavior may contribute to the large variations in HIV prevalence by region in Ethiopia. Population-level interventions to reduce risky sexual behavior in high HIV incidence regions should be considered.

    A study on ectoparasites of small ruminants in three selected agro-ecological sites of Tigray Region, Ethiopia disclosed an overall prevalence of 55.5% and 58% in each examined 750 sheep and goats, respectively. In the sheep population, Melophagus ovinus (19.1%), tick infestations (16%), Damalinia ovis (15.3%), Linognathus africanus (11.5%), and Ctenocephalides felis (9%) were the major ectoparasites. The major ectoparasites identified in goats were tick infestations (29.7%), L. africanus (27.9%), Sarcoptes scabiei var. caprae (12.5%), C. felis (11.1%), and Demodex caprae (6.8%). In sheep, there was a statistically significant difference (P consciousness and awareness of farmers, and weak animal health extension services are believed to have contributed for widespread distribution and occurrences of ectoparasites. The growing threat of ectoparasites to small ruminant production and the tanning industry needs well-coordinated and urgent control intervention.

    The study determined the prevalence and major types of gastrointestinal parasites in pigs and assessed the health management practices on farms in Burayu District in West Shoa Zone of Oromia Regional State, Ethiopia. The study was performed from November 2007 to April 2008 using standard coprological examination and a well-organised questionnaire survey. Of the 272 pigs examined for the presence of gastrointestinal parasites, 36 (13.2%) were infected with one or more types of parasite. Neither age nor management system proved to be a statistically significant factor in the prevalence of parasites. The highest prevalence of parasites was recorded in December, January and April, whereas the lowest was observed in February. Significant variation in the prevalence of parasites was noticed amongst study months. The majority of farmers did not use acaricides to treat and control external parasites. Anthelmintics were not used by any of the farmers. Some 76.1% of the farmers never used any type of treatment for sick pigs; 21.7% of the farmers used modern treatment and 2.2% of the farmers used traditional medicines. More than 95.0% of pigs were kept on soil floors and only 10.9% of the housing systems had good ventilation. Dung was removed at least every three days, with the majority of farmers (91.2%) removing it every morning. This study provided evidence for the occurrence of internal parasites in pigs kept in Burayu District in Oromia. Further epidemiological studies are needed to determine the zoonotic and economic importance of pig parasites in other parts of Ethiopia.

    2016-06-01

    Full Text Available The Amhara National Regional State is lying between the Abay and Tekeze rivers with vast territory, endowed with varied climatic regions and different kinds of natural recourses. It is one of the areas of earliest settlement in Ethiopia as a result of which has been experiencing high deterioration of natural resources. The rugged and steep escarpments and the frequently incised topography are making the construction of road transportation very difficult and expensive in financial terms. Moreover, landslides and severely eroded gullies in regions of heavy precipitations have exacerbated the problems to enhance the road network of the area as a result of which it remained far from adequacy for the population of the region. Even today the transport map of the region is most impressive by it bareness. Generally, the overall results of this study indicate that the road network in the Amhara National Regional State is with single connection tree like shape with few extended arms, with the value of Beta index less than 1, Cyclomatic number equals 0, Gamma index between 0-0.42, Alpha index ranging between 0-0.6. These results show that most of the areas in Amhara region are inaccessible and need a long distance travel to access the nearest road. Based on these empirical findings and the reviewed literature, the researcher would like to recommend that the construction of more road networks is imperative in Amhara region taking into account the socio-economic importance of the areas to be connected to the main road system of the country.

  2. Changes in the frequency and severity of hydrological droughts over Ethiopia from 1960 to 2013

    KAUST Repository

    El Kenawy, A. M.

    2016-06-27

    Here we present an analysis of drought occurrence and variability in Ethiopia, based on the monthly precipitation data from the Climate Research Unit (CRU-v3.22) over the period from 1960 to 2013. The drought events were characterized by means of the Standardized Precipitation Index (SPI) applied to precipitation data at a temporal scale of 12 months. At the national scale, the results reveal a statistically significant decrease in the severity of droughts over the 54-year period, a pattern that is mostly attributed to a statistically significant decrease in the frequency of high intensity drought episodes (i.e., extreme and very extreme droughts), compared to moderate droughts. To assess the general patterns of drought evolution, a principal component analysis (PCA) was applied to the SPI series. PCA results indicate a high spatial heterogeneity in the SPI variations over the investigated period, with ten different spatially well-defined regions identified. These PCA components accounted for 72.9% of the total variance of drought in the region. These regions also showed considerable differences in the temporal variability of drought, as most of the regions exhibited an increase in wetness conditions in recent decades. In contrast, the regions that receive less than 400 mm of annual precipitation showed a declining  trend, with the largest changes occurring over Afar region. Generally, the highly elevated regions over the central Ethiopian Highlands showed the weakest changes, compared to the lowlands. This study confirms the local character of drought evolution over Ethiopia, providing evidence for policy makers to adopt appropriate local policies to cope with the risks of drought. Over Ethiopia, the detailed spatial assessment of drought evolution is required for a better understanding of the possible impacts of recurrent drought on agriculture, food production, soil degradation, human settlements and migrations, as well as energy production and water resources

    A common issue at volcanic passive margins (VPM) is the lack of observation of the structures that accommodate stretching and thinning. Indeed, the most distal parts and the Ocean-Continent Transition is often masked by thick seaward-dipping reflectors (SDR) sequences. Some current challenges are then to know if the observed thinning fit the divergence (thinning vs dyking); and what is the rheological effect of magma supply that re-thickens the crust during extension? In the Central Afar magmatic rift (Ethiopia), the structures related to rifting since Oligocene are cropping out onshore and are well preserved. We present here a new structural model based on field data and lavas (U-Th/He and K/Ar) datings along a balanced cross-section of the Central Afar Western Margin. We mapped continent-ward normal fault array affecting highly tilted trapp series (29-30 Ma) unconformably overlain by tilted Oligo-Miocene (25-7 Ma) acid series. The main extensional and necking/thinning event took place during the end of this Miocene magmatic episode. The Pliocene flood basalt (Stratoid series) is erupted over an already thinned crust. The bulk extension for the Afar Western Margin is ß ~ 2.50. Our main findings are: - Oligo-Miocene deformation in Central Afar appears to be largely distributed through space and time ("magmatic wide rift"). It has been accommodated in a 200-300 km wide strip being a diffuse incipient plate boundary during the whole rifting history until the formation of present-day magmatic segments. There is a period of tectonic quiescence accompanied with few magma erupted at the surface between 25 Ma and 7 Ma. We suggest that tectonic and magmatic activity was focused at that time on the highly faulted Danakil block and Southern Red Sea, away from our study zone. - ß ~ 2.50 is higher than the thinning factor of ~1.30 observed in geophysical studies. We propose that the continental crust in Central Afar has been re-thickened during extension by the syn

Seven hundred thirty sera samples (421 of sheep and 309 of goats) were randomly collected from purposively selected villages of the study area. Structured questionnaire format was developed, pre-tested and administered to assess the perception of the community pertaining to brucellosis in sheep and goats. Sera samples were screened by Rose Bengal Plate Test (RBPT), and all samples tested positive by the RBPT were subjected to Complement Fixation Test (CFT) for confirmation. Of 12 serum samples that were positive by RBPT, 11 were positive by CFT. Statistically significant differences were not observed between the species as well as the sex groups (P > 0.05); however, the variation between the age groups was statistically significant (P brucellosis in their livestock and exposes the community to a public health hazard. In general, the sero-prevalence in the study area was not so high; nevertheless, appropriate brucellosis control and prevention methods should be implemented to circumvent future potential for economic losses and the public health hazard of the disease.

    Full Text Available Soil map is one of the basic tools in any agricultural development planning and generating a digital one is even more effective and more productive for natural resources evaluation. Moreover, remote sensing and GIS have added to soil classification different concept and enforcement. The study aim was to produce digital soil maps for the study area following different classification systems (ST and WRB and to define the spatial distribution and characteristics all the soil classes in the study area, which will be indispensable for future development planning. This work has been done as a part of the 29th Course Professional Master in IAO institution, Florence, Italy. The study area was Kilte Awulaelo district in Tigray region, Ethiopia, Which is characterized by different topographies and geomorphologies with different agro ecological conditions. Eleven main soil groups and sixty soil types were identified in the study area. The main soil groups are: Leptosols, Vertisols, Fluvisols, Stagnosols, Kastanozems, Phaeozems, Calcisols, Luvisols, Arenosols, Cambisols and Regosols.  Regosols and Cambisols are the dominant soils in the study area which is characteristic soils of rainfed agriculture and land affected by erosion. Using spatial distribution map of each soil group was very helpful to connect soil characteristics with soil forming factors. Lastly, GIS and remote sensing were very effective tools in this study and gave higher value for the final study results.

    Adequate supplies of tuberculosis laboratory reagents and consumables are necessary for tuberculosis diagnosis and monitoring of treatment response. This study assessed the distribution and stock levels of laboratory commodities used in tuberculosis control in health centers of Amhara region, Ethiopia. A cross-sectional study was conducted in 82 health centers, among 801, providing sputum microscopy services. Stock levels were calculated, and distribution of reagents and consumables assessed. Thirty three (40.2%) health centers were under stocked for at least one of the key items for tuberculosis diagnosis at the time of visit. Fifteen (18.3%) health centers had no stocks of at least one of the key items (methylene blue (11%), carbol fuchsin (11%), acid alcohol (8.5%) and sputum cups (3.7%)). Of the 82 health centers, 77 (93.9%) did not fulfill the criteria for effective distribution of tuberculosis laboratory reagents and consumables. There were many health centers that had no or only low stocks of key tuberculosis laboratory reagents and consumables as a result of ineffective distribution system. It is necessary to strengthen supply chain management to ensure uninterrupted TB diagnostic service.

    The hot springs in Ethiopia are concentrated in two areas: the North Afar depression and adjacent Red Sea shore, and a geothermal field 100 km from northeast to southwest in the central part of Ethiopia. The latter extends not only to the Great Rift Valley but also to the Aden Gulf. In the lake district in the central Great Rift Valley, there are a number of hot springs on the lake shore. These are along NE-SW fault lines, and the water is a sodium bicarbonate-type rich in HCO/sub 3/ and Na but low in C1 and Ca. In Dallol in the North Afar depression, CO/sub 2/-containing hot springs with high temperatures (110/sup 0/C) and a specific gravity of 1.4, were observed. In the South Afar depression, located in the northeastern part of the Rift Valley, there are many active volcanoes and hot springs between the lake district and the Danakil depression. The spring water is a sodium bicarbonate saline type. Nine graphs and maps are included.

  9. Undertaking cause-specific mortality measurement in an unregistered population: an example from Tigray Region, Ethiopia

    Full Text Available Background: The lack of adequate documentation of deaths, and particularly their cause, is often noted in African and Asian settings, but practical solutions for addressing the problem are not always clear. Verbal autopsy methods (interviewing witnesses after a death have developed rapidly, but there remains a lack of clarity as to how these methods can be effectively applied to large unregistered populations. This paper sets out practical details for undertaking a representative survey of cause-specific mortality in a population of several million, taking Tigray Region in Ethiopia as a prototype. Sampling: Sampling was designed around an expected level of maternal mortality ratio of 400 per 100,000 live births, which needed measuring within a 95% confidence interval of approximately ±100. Taking a stratified cluster sample within the region at the district level for logistic reasons, and allowing for a design effect of 2, this required a population of around 900,000 people, equating to six typical districts. Since the region is administered in six geographic zones, one district per zone was randomly selected. Implementation: The survey was implemented as a two-stage process: first, to trace deaths that occurred in the sampled districts within the preceding year, and second to follow them up with verbal autopsy interviews. The field work for both stages was undertaken by health extension workers, working in their normally assigned areas. Most of the work was associated with tracing the deaths, rather than undertaking the verbal autopsy interviews. Discussion: This approach to measuring cause-specific mortality in an unregistered Ethiopian population proved to be feasible and effective. Although it falls short of the ideal situation of continuous civil registration and vital statistics, a survey-based strategy of this kind may prove to be a useful intermediate step on the road towards full civil registration and vital statistics implementation.

    Chat (Catha edulis) is an important perennial crop and its leaves are chewed for a stimulating effect. It is widely cultivated in the Ethiopian highlands of Oromia region and is figured as Ethiopia's second largest foreign exchange earner. Its cultivation accounts for about 70% of farmer's income in the study area. The common effect of its consumption leads to insomnia, a condition that the users sometimes try to overcome with sedatives or alcohol. The present study is an attempt to survey and assess the impact of crop on the community. It has been observed to implicate health problems, reduces savings and nutritional standards of the family members. The chat yields in the area ranges from 1500-1800 kg/ha through monoculture. During the study, the average monthly income of the family practicing chat cultivation was from Birr 8, 533.00 to 13, 166.00 kg/ha per year in Baate and Genede cultivating areas. When the average cost per/ha was rupees 60/kg. The present study shows that during the recent past, leaf consumption has increased significantly. Chat growers are not only producers but also traders and consumers. Its consumption has become a widespread habit from secondary schools. Highest number of consumers was found to be among drivers followed by students and shopkeepers. The consumption of the plant is not considered a taboo but on contrary a status symbol in the region. It has no legal or moral implications and is considered as a part of custom and habit of local people. High value cash crop like vegetables and orchard fruits needs to be used as a replacement for chat which could be a regular source of income to farmers. Alternative sources of income for farmers needs to be scientifically worked out and proposed keeping in view the proportion of agricultural land reserved under chat cultivation and to increase the production of food grains being produced.

    2003-11-01

    We studied the seismic activity of the Afar Depression (AD) and adjacent regions during the period 1960-2000. We define seven distinct seismogenic regions using geological, tectonic and seismological data. Based on the frequency-magnitude relationships we obtain b-values of about 1 for the different regions. The pattern of the distribution of the location of epicentres fits with the known active fault zone in the AD and the axial volcanic ridges. The Bab el Mandab area and the Danakil-Aysha'a blocks are less active. For 125 intermediate to strong earthquakes the seismic moment and source parameters were calculated. The results of the fault plane solutions for the Afar Depression indicate mainly strike-slip and normal sense of movement originating from fault planes striking NW-SE. These results indicate a clockwise block rotation described previously as a bookshelf model in central AD. There are a few right-lateral faults east of Massawa with E-W-striking fault planes. At the southern Red Sea, north of the Danakil block, the mixed focal mechanisms, with axial plane striking NW-SE, comprise several reverse faulting, strike-slip motion and normal faulting. Right-lateral movement was also calculated for a cluster of seismic events between the Manda Hararo and Alyata volcanic ridges along NW-SE-striking faults. Along the N-S-striking faults in the escarpment, at the western Afar margins, there are two distinct clusters of epicentres. The strong earthquakes at the southern cluster exhibit normal or strike-slip motions. The intermediate to small earthquakes in the northern cluster exhibit reverse and strike-slip motions. Mainly normal faults were calculated along NE-SW-striking faults of the Ethiopian East African Rift. Estimates of the seismic efficiency suggest that the maximal values are about 50 per cent or less, implying that most of the motion is taken aseismically.

    Maternal health service utilizations are poorly equipped, inaccessible, negligible, and not well documented in the pastoral society. This research describes a quantitative and qualitative study on the determinants of institutional delivery among pastoralists of Liben Zone with special emphasis on Filtu and Deka Suftu woredas of Somali Region, Ethiopia. The study was funded by the project “Fostering health care for refugees and pastoral communities in Somali Region, Ethiopia”. This community-based cross-sectional study was conducted during November 2015. Interviews through a questionnaire and focus group discussions were used to collect the data. Proportional to size allocation followed by systematic sampling technique was used to identify the study units. The major determinants of institutional delivery in the study area were as follows: being apparently healthy, lack of knowledge, long waiting time, poor quality services, cultural beliefs, religious misconception, partner decision, and long travel. Around one-third (133, 34.5%) of the women had visited at least once for their pregnancy. More than half (78, 58.6%) of the women had visited health facilities due to health problems and only 27 (19.9%) women had attended the recommended four antenatal care visits. Majority (268, 69.6%) of the pregnant women preferred to give birth at home. Women who attended antenatal care were two times more likely to deliver at health facilities (AOR, 95% confidence interval [CI] =2.38, 1.065–4.96). Women whose family members preferred health facilities had 14 times more probability to give birth in health institutions (AOR, 95% CI =13.79, 5.28–35.8). Women living in proximity to a health facility were 13 times more likely to give birth at health facilities than women living far away (AOR, 95% CI =13.37, 5.9–29.85). Nomadic way of life, service inaccessibility, and sociodemographic and cultural obstacles have an effect on the utilization of delivery services. Increasing

In Ethiopia, there is no comprehensive research that presents the whole picture of HAIs in hospitals. The objective of this study was to examine the nature and extent of HAIs in Ethiopia. Methods: A repeated cross-sectional study was conducted in two teaching hospitals. All eligible inpatients admitted for at least 48 hours on the day of the survey were included. The survey was conducted in dry and wet seasons of Ethiopia, that is, in March to April and July 2015. Physicians and nurses collected the data according to the Centers for Disease Control and Prevention definition of HAIs. Coded and cleaned data were transferred to SPSS 21 and STATA 13 for analysis. Univariate and multivariable logistic regression analyses were used to examine the prevalence of HAIs and relationship between explanatory and outcome variables. Results: A total of 908 patients were included in this survey, the median age of the patients was 27 years (interquartile range: 16–40 years. A total of 650 (71.6% patients received antimicrobials during the survey. There were 135 patients with HAI, with a mean prevalence of 14.9% (95% confidence interval 12.7–17.1. Culture results showed that Klebsiella spp. (22.44% and Staphylococcus aureus (20.4% were the most commonly isolated HAI-causing pathogens in these hospitals.

  16. Probing the age and temperature of rifting in Afar

    2014-05-01

    Rifting along the southern part of the Red Sea margin in NE Africa (leading to formation of Afar) has been closely associated with magmatic activity since the initiation of extension at around ~ 25Ma. Numerous active volcanoes are currently found along rift zones here and magma intrusion into the crust has potentially accommodated significant amounts of extension. This extensive present-day volcanism has been linked to elevated mantle temperature, perhaps due to a thermal plume, or as a consequence of passive flow in the mantle beneath the extending lithosphere. Geochemical evidence for basaltic lavas erupted in Afar have been used to suggest that mantle temperatures are in the range 1370 to 1490°C, and that the region is currently experiencing late stage rifting. Analysis of changes in shear wave seismic velocities and relative travel time tomography suggests mantle temperatures are within a similar range, yet the region has greater similarities to a young spreading centre. The range in potential temperature estimates is however very large, with different implications for the volcanic history of the region and hence timing of break-up. Rather than focusing a single observable, we use a relatively straight forward model of extension and decompression melting to predict the seismic-velocity and attenuation structure of the asthenosphere and lithosphere, synthetic receiver functions as a result of this seismic structure, crustal thickness as a result of decompression and finally the melt composition. From this combined study we find that melt composition and seismic structure are dependent on both temperature and time. If mantle potential temperature is 1350°C then both the seismic structure and melt composition can be matched if the duration of extension is more than 30 Myr. However this is longer than the estimated duration of extension from plate reconstructions, and given the low rate of extension in Afar, this cold model only generates up to 5 km of igneous

  17. Gravity field and isostatic state of Ethiopia and adjacent areas

    Over 35,000 onshore and offshore gravity stations have been compiled in order to test isostatic models against geologic structures over a part of the Afro-Arabian shield. The area of Ethiopia covers an important part of this system because it contains the major section of the ≈5000 km Afro-Arabian rift and includes the transition between the Arabo-Nubian-Shield (ANS) and the Mozambique Belt (MB). Isostatic residual anomalies have been calculated using both Airy and Vening-Meinesz (flexural rigidity D = 10 22 Nm) models. The isostatic residual anomalies outline the major Precambrian belts, the Cenozoic rifts and associated major structures. Positive residual anomalies associated with the main Ethiopian Rift (MER) and Kenyan rift systems could be the expressions of an axial intrusive body and swarms of local faults and fractures. The residual anomalies indicate relative stability in the MER and increased tectonic activity in the areas of the Red Sea, Gulf of Aden and Afar. Near-zero isostatic residuals flank the MER and Kenya rifts and are found within the Danakil Alps and some plateau regions. The small mean isostatic residual anomaly (about 8 mGal) and the isostatic analysis show a slight positive bias indicating under compensation. The undercompensation may imply that there are upper crustal features that are not compensated regionally (probably supported by the rigidity of the lithosphere) and isostatic disequilibrium in the region. Therefore, the high topography of Ethiopia and East African plateau is partly compensated by thicker crust (broad negative isostatic regional anomaly) and partly by dynamic forces. The results of the qualitative interpretation form the basis of continuing three-dimensional gravity modelling and quantitative analysis that also integrates data from eastern Sudan.

    Hydrological variability and seasonality is one of the Ethiopia's primary water resource management challenges. Variability is most obviously manifest in endemic, devastating droughts and floods. While the level of flooding is quite often extremely high and destroys human beings and property, in many cases flooding is of vital importance because the community benefits from flood recession agriculture. This is the case of the lower Omo plain whose agriculture is based on the regularity of the inundations due to flooding of the Omo Gibe River. The big flood in 2006, which caused death for more than 300 people and 2000 cattle, poses a dilemma. Flooding must be controlled and regulated in a way that the damages are reduced as much as possible but the flooding-related benefits are not lost. To this aim, characterization and understanding of hydrological variability of the Omo Gibe River basin is fundamental. The goal of this work is to extract the maximal amount of information on the hydrological variability and specially on the flooding regime from the few data available in the region. Because most of the basin is ungauged, hydrological information is reconstructed using the data from 9 gauged catchments. A daily water balance model has been developed, calibrated and validated for 9 gauged catchments and, subsequently, the parameters have been correlated to catchment characteristics in order to establish a functional relationship that allows to apply the model to ungauged catchments. Daily streamflow has been predicted for 15 ungauged catchments, which are assumed to comprehensively represent the hydrological variability of the Omo-Gibe River Basin. Even though both northern and southern catchments are affected by a strong seasonality of precipitation, with most of the rain falling in less than 3 months, most of the northern catchments are humid, while in the southern part of the Omo-Gibe River basin, the catchments are either humid, dry sub humid, semiarid or arid.

    This research aimed at investigating how an inventory of geomorphosites can foster or improve the knowledge and management of geomorphological heritages in the context of developing countries. Accordingly, a geomorphosite inventory in the Simen Mountains National Park (SMNP), Ethiopia was conducted following the method of Reynard et al. (2015). The national context of geoheritage and geoconservation in Ethiopia was appraised and a road map for the management of the inventoried sites in the SMNP was elaborated. Ethiopia hosts numerous geoheritage sites, some of which of highest international significance. Therefore, geotourism has recently been promoted throughout the country (Asrat et al., 2008). Despite numerous trials of the scientific community, there is not yet a national policy for geoconservation in the country. Many parts of Ethiopia are underdeveloped in terms of economic subsistence and infrastructure, making these immediate priorities over conservation efforts. Nevertheless, this study showed that the Simen Mountains have the potential to become a UNESCO Global Geopark and that geosites could be used to develop geotourism within SMNP, and that development and conservation are not contradictory. Twenty-one geomorphosites were identified and assessed. Diverse geomorphological contexts including fluvial, structural, glacial, periglacial, anthropic and organic characterize the SMNP. The temporal stages, which allow the reconstitution of the morphogenesis of the Simen Mountains, are the Cenozoic volcanism, Last Glacial Maximum, Holocene as well as historic/modern landscape modification. Four synthesis maps were elaborated to present the results of the assessment. The average scientific value of the inventoried geomorphosites is very high compared to other inventories realized using the same method. This is particularly due to the extremely high integrity of the sites. Almost all geomorphosites are in a good state of conservation and only few sites are

Thus, new drugs are required against drug-resistant Plasmodium strains. Historically, many of the present antimalarial drugs were discovered from plants. This study was, therefore, conducted to document antimalarial plants utilized by Sidama people of Boricha District, Sidama Zone, South Region of Ethiopia. An ethnobotanical survey was carried out from September 2011 to February 2012. Data were collected through semistructured interview and field and market observations. Relative frequency of citation (RFC was calculated and preference ranking exercises were conducted to estimate the importance of the reported medicinal plants in Boricha District. A total of 42 antimalarial plants belonging to 27 families were recorded in the study area. Leaf was the dominant plant part (59.0% used in the preparation of remedies and oral (97.4% was the major route of administration. Ajuga integrifolia scored the highest RFC value (0.80. The results of this study revealed the existence of rich knowledge on the use of medicinal plants in the study area to treat malaria. Thus, an attempt should be made to conserve and evaluate the claimed antimalarial medicinal plants with priority given to those that scored the highest RFC values.

    The Afar Depression is a highly extended region of continental to transitional oceanic crust lying at the junction of the Red Sea, the Gulf of Aden and the Ethiopian rifts. We analyze the evolution of the Afar crust using plate kinematics and published crustal models to constrain the temporal and volumetric evolution of the rift basin. Our reconstruction constrains the regional-scale initial 3D geometry and subsequent extension and is well calibrated at the onset of rifting (˜20 Ma) and from the time of earliest documented sea-floor spreading anomalies (˜6 Ma Red Sea; ˜10 Ma Gulf of Aden). It also suggests the Danakil block is a highly extended body, having undergone between ˜200% and ˜400% stretch. Syn-rift sedimentary and magmatic additions to the crust are taken from the literature. Our analysis reveals a discrepancy: either the base of the crust has not been properly imaged, or a (plume-related?) process has somehow caused bulk removal of crustal material since extension began. Inferring subsidence history from thermal modeling and flexural considerations, we conclude subsidence in Afar was virtually complete by Mid Pliocene time. Our analysis contradicts interpretations of late (post 3 Ma) large (˜2 km) subsidence of the Hadar area near the Ethiopian Plateau, suggesting paleoclimatic data record regional, not local, climate change. Tectonic reconstruction (supported by paleontologic and isotopic data) suggests that a land bridge connected Africa and Arabia, via Danakil, up to the Early to Middle Pliocene. The temporal constraints on land bridge and escarpment morphology constrain Afar paleogeography, climate, and faunal migration routes. These constraints (particularly the development of geographic isolation) are fundamentally important for models evaluating and interpreting biologic evolution in the Afar, including speciation and human origins.

  3. How Sustainable Is Transnational Farmland Acquisition in Ethiopia? Lessons Learned from the Benishangul-Gumuz Region

    Full Text Available Due to the nature of available land as one of the main attractions for investment, land lease marketing in Sub-Saharan Africa is appearing on policy agenda. This paper describes critical land-related institutional and governmental frameworks that have shaped the contemporary land governance and land lease contracts in Ethiopia. It also examines the effectiveness of the land lease process regarding economic, social, and environmental expectations from agricultural outsourcing. Both qualitative and quantitative data analyses were used and results showed that the size of the land cultivated by investors is significantly lower than the agreed-upon size in the contract. Besides, the supply of land to large-scale commercial investors in Ethiopia is made without adequate land use planning, land valuation, and risk analysis. Furthermore, limitations in monitoring systems have contributed to meager socio-economic gains and led to deforestation. Accordingly, the study concludes that supplying vast tracts of farmland to large-scale agricultural investors requires integrated land use planning, land valuation and governance, monitoring systems, and a capacity to implement the various social and environmental laws in coordination with other sectors. Improving rural infrastructure, particularly road, is also indispensable to enhance the level of performance of commercial farms. Last but most importantly, the customary land holding rights of residents should be respected and institutionally recognized.

    This study was carried out from October 2012 to end of February 2013 in and around Kombolcha, Amhara regional state, Ethiopia, using a total of 201 neonatal calves aged 1 day to 4 months and suffering from diarrhea. The objectives of the study were to isolate Escherichia coli from diarrheic calves, and to determine E. coli biotypes and risk factors associated with its isolation. The fecal samples were collected, transported, and processed following standard microbiological procedures. Seventy-four isolates of E. coli were identified. Yellowish diarrhea, younger age, and low-colostrum feeding were significantly associated with rate of E. coli isolation (P calf diarrhea, with very diverse biotypes.

    Radar interferometric measurements of ground-surface displacement using ERS data show a change in radar range, corresponding to up to 12 cm of subsidence near Gada ‘Ale volcano in northern Afar, Ethiopia, that occurred between June 1993 and May 1996. This is the area of lowest topography within the Danakil Depression (-126 m). Geodetic inverse modeling and geological evidence suggest a volcanic origin of the observed deformation; it was probably caused by a combined process of magma withdrawal from a larger reservoir and normal faulting. There is no evidence of subaerial eruption. This is the only identifiable deformation event during June 1993-October 1997 in the 80 km long Erta ‘Ale volcanic range, indicating surprising inactivity elsewhere in the range.

    As continental rift zones mature the tectonic and volcanic processes associated with crustal extension become confined to narrow magmatic rift zones, reminiscent of oceanic spreading ridges. The formation of these rift zones and the development of ocean-ridge type topography is a significant milestone in rift evolution as it signifies the localization of crustal extension and rift-related volcanism. Here we show that lavas, which erupted since ~200 ka along part of the on-land Red Sea rift system in Afar, Ethiopia, have a consistent age-progression from the rift axis outwards, indicating that axial dyke intrusion has been the primary mechanism of segment growth and that focused magmatic accretion and extension in the crust have remained stable here over this period. Our results suggest that as this rift segment has formed, in thinned and intruded continental crust, the time-averaged surface opening rate has closely approximated the total extension rate between Africa and Arabia.

    Objective: To assess the prevalence of anemia in children with urinary schistosomiasis, malaria and concurrent infections by the two diseases. Methods: Urine and blood samples were collected from 387 children (216 males and 171 females) to examine urinary schistosomiasis and malaria and to determine hemoglobin concentration at Hassoba and Hassoba Buri village in Amibara woreda, Afar region, Ethiopia. Results: The overall prevalence of urinary schistosomiasis and Plasmodium falciparum malaria was 24.54% and 6.20% respectively. Only 2.84% of children carried concurrent infections of both parasites. There was high percentage of anemic patients (81.81%) in the coinfected cases than in either malaria (33.3%) or schistosomiasis (38.94%) cases. There was significantly low mean hemoglobin concentration in concurrently infected children than non-infected and single infected (P0.05). The level of hemoglobin was negatively correlated with the number of S. haematobium eggs/10 mL urine (r=-0.6) and malaria parasitemia (r=-0.53). Conclusions: The study showed that anemia is higher in concurrently infected children than non-infected and single infected. Furthermore, level of hemoglobin was negatively correlated with the number of S. haematobium eggs and malaria parsitemia. Therefore, examination of hemoglobin status in patients co-infected with malaria and schistosomiasis is important to reduce the risk of anemia and to improve health of the community.

    Full Text Available Little is known about sexual risks and associated factors about female youths in semi-urban areas of Ethiopia. This study aimed to describe the nature and magnitude of risky sexual behaviors, and the socio-demographic and behavioral determinants among female youths in Tiss Abay, a semi-urban area on the outskirts of Bahir Dar City of the Amhara Region in northern Ethiopia.A cross-sectional census type study was conducted among female youths who were unmarried and aged 15-29 years in September 2011.711 female youths participated in the study, with the mean age of initiation of sex of 78.6% being16.73±2.53 years. Only 52(9.3% used condom during the first sex. Within the last 12 months, 509(71.6% had sexual intercourse and 278(54.6% had two or more sex partners, and 316(62.1% did not use condom during their last sex. Sex under the influence of substances was reported by 350(68.8%, and a third of the recent sexes were against the will of participants. One or more risky sexual practices were reported by 503(70.3% participants, including: multiple sexual partnerships, inconsistently using or not using condoms, sex under the influence of alcohol and/or sex immediately after watching pornography. Age group, current marital status, drinking homemade alcohol, chewing 'khat', watching pornography and using any form of stimulant substances were the predictors of risky sexual behavior. Watching pornography before sex and sex for transaction were the predicators of not using condom during most recent sex.Risky sexual behaviors were very common among the female youths in Tiss Abay. Initiation of context-based interventions, such as raising awareness about the risks, safer sex practices, condom promotion and integration of gender issues in the programs are recommended.

    We conducted a case-control study to evaluate risk factors for visceral leishmaniasis during an epidemic in a previously unaffected district of Ethiopia. We also collected blood and bone marrow specimens from dogs in the outbreak villages. In multivariable analyses of 171 matched case-control pairs, dog ownership, sleeping under an acacia tree during the day, and habitually sleeping outside at night were associated with significantly increased risk. Specimens from 7 (3.8%) dogs were positive by immunofluorescent antibody test (IFAT) and both enzyme-linked immunosorbent assays (ELISAs), whereas Leishmania DNA was detected in 5 (2.8%) bone marrow aspirates (from 3 seropositive and 2 seronegative dogs). Insecticide-treated nets may only protect a portion of those at risk. Further research on the vectors, the role of the dog in the transmission cycle, and the effect of candidate interventions are needed to design the best strategy for control.

    Full Text Available Abstract Background Engaging all health care providers in tuberculosis (TB control has been incorporated as an essential component of World Health Organization's Stop TB Strategy and the Stop TB Partnership's global plan 2006-2015. Ethiopia has a growing private health sector. The objective of the present study was to investigate the role of private practitioners (PPs in TB case detection and assess their perspectives on TB treatment delay in Amhara Region, Ethiopia. Results A cross-sectional study among 112 PPs selected from private health facilities (PHF in the region was conducted. The study was carried out between May and August 2008 and data was collected using a semi-structured questionnaire. Group differences were analyzed using one-way Anova test and a p-value of In this study, PPs saw a median of 12 TB suspects and 1.5 patients a week. The mean number of TB suspects and patients seen varied significantly among the different professions with p Conclusion PPs manage a substantial number of TB suspects and patients in Amhara Region, Ethiopia. The GHF delay observed among TB patients referred by PPs to GHF is unnecessary. Expanding PPM-DOTS in the region and improving the quality of TB care at both government and private health facilities reduces treatment delay and increases TB case detection.

    The Cenozoic history of the western Ogaden region of Ethiopia, between the Ethiopian rift and the South Afar margin, is marked by uplift and incision of the Ogaden plateau down to the Gorrahei Formation, an upper Cretaceous evaporite formation. Debuttressing of this and the overlying sedimentary formations resulted in widespread and spectacular gravitational spreading landforms over a minimum surface area of 15,000 km2, most of which remains unstudied. After clearing up some misconceptions about the surface geology of the study area, the Kebenawa Ridge in the Audo Range, observations are reported that point to a tectonic style controlled by halokinesis and subsequently, gravitational spreading. The role of diapirism and karstification in the observed halokinesis is discussed, as well as the influence of halokinesis on gravitational spreading. Spreading is in part akin to sackung, in that ridge deformation features include a crestal graben and basal ridge topography extrusion, and deformation was triggered by lateral ridge debuttressing. Ridge spreading also presents analogy with gravitational spreading of the Canyonlands grabens in the Needles District, Canyonlands National Park, Utah. The scale and the mechanisms are found to be basically similar, but two differences are noted. First, incision by the drainage network in response to plateau uplift in Ethiopia has debuttressed the topography along two parallel rivers, instead of a single river (the Colorado River) in Utah. Secondly, incision proceeded to the base of the evaporite layer in the Ogaden, whereas incision has not exceeded the top of the evaporite layer in Utah. These differences may have influenced the details of the spreading mechanisms in ways that remain to be investigated. Overall, in Ethiopia, association of halokinesis and a transitional mode of gravitational spreading at the interface between narrow ridge spreading (sackung) and plateau spreading (Canyonlands-type), illustrates a fascinating and

    In 2004, Ethiopia introduced a community-based Health Extension Program to deliver basic and essential health services. We developed a comprehensive performance scoring methodology to assess the performance of the program. A balanced scorecard with six domains and 32 indicators was developed. Data collected from 1,014 service providers, 433 health facilities, and 10,068 community members sampled from 298 villages were used to generate weighted national, regional, and agroecological zone scores for each indicator. The national median indicator scores ranged from 37% to 98% with poor performance in commodity availability, workforce motivation, referral linkage, infection prevention, and quality of care. Indicator scores showed significant difference by region (P < 0.001). Regional performance varied across indicators suggesting that each region had specific areas of strength and deficiency, with Tigray and the Southern Nations, Nationalities and Peoples Region being the best performers while the mainly pastoral regions of Gambela, Afar, and Benishangul-Gumuz were the worst. The findings of this study suggest the need for strategies aimed at improving specific elements of the program and its performance in specific regions to achieve quality and equitable health services.

Interestingly, 9 species were used to treat spiritual ailments and to expel demons. In most cases of medicinal applications the leaves or roots were employed.Traditional plant knowledge has clearly declined in a large part of the research area. Western style health care services as provided by governments and NGOs, in particular in rural areas, seem to have contributed to a decline in traditional knowledge, in part because the local population simply regards western medicine as more effective and safer.

    Full Text Available Mobile populations present unique challenges to malaria control and elimination efforts. Each year, a large number of individuals travel to northwest Amhara Region, Ethiopia to seek seasonal employment on large-scale farms. Agricultural areas typically report the heaviest malaria burden within Amhara thereby placing migrants at high risk of infection. Yet little is known about these seasonal migrants and their malaria-related risk factors.In July 2013, a venue-based survey of 605 migrant laborers 18 years or older was conducted in two districts of North Gondar zone, Amhara. The study population was predominantly male (97.7% and young (mean age 22.8 years. Plasmodium prevalence by rapid diagnostic test (RDT was 12.0%; One quarter (28.3% of individuals were anemic (hemoglobin <13 g/dl. Nearly all participants (95.6% originated from within Amhara Region, with half (51.6% coming from within North Gondar zone. Around half (51.2% slept in temporary shelters, while 20.5% regularly slept outside. Only 11.9% of participants had access to a long lasting insecticidal net (LLIN. Reported net use the previous night was 8.8% overall but 74.6% among those with LLIN access. Nearly one-third (30.1% reported having fever within the past two weeks, of whom 31.3% sought care. Cost and distance were the main reported barriers to seeking care. LLIN access (odds ratio [OR] = 0.30, P = 0.04 and malaria knowledge (OR = 0.50, P = 0.02 were significantly associated with reduced Plasmodium infection among migrants, with a similar but non-significant trend observed for reported net use the previous night (OR = 0.16, P = 0.14.High prevalence of malaria and anemia were observed among a young population that originated from relatively proximate areas. Low access to care and low IRS and LLIN coverage likely place migrant workers at significant risk of malaria in this area and their return home may facilitate parasite transport to other areas.

    Full Text Available This study was conducted to assess cattle marketing practice in the crop-livestock production system areas of the highland, mid-altitude and pastoralists in the lowlands of Guradamole Woreda of Bale zone of Ethiopia. That is conducted from July 2015 to 2015 March. Cattle marketing practice were assessed based on market monitoring and questionnaire survey in each altitude. A total of 100 farmers were selected randomly from 10 peasant associations which are selected from each altitude based on proportion of peasant association in each altitude. Market monitoring was done at two livestock marketing places of Rayitu town and Jibri, which is capital city of Guradamole Woreda. Cattle marketing varied considerably across the peasant associations and marketing places. Cattle supplied to markets include calves, heifers, bulls and oxen, dry and lactating cows. Who often supply cattle to marketing places are farmers and pastoralists from Guradamole Woreda and neighboring ethnic societies. Livestock market infrastructure and management are among the key constraints to the development and sustainable management of livestock markets. Long trekking distances to markets are a significant impediment to pastoralists’ ability to profitably sell their cattle. During drought periods, animals lose weight on the journey to market, which significantly lowers their value. In some cases, animals are too weak to embark on the homeward journey, forcing producers to sell at very low prices. Poor and uneven access to market information remains a major constraint for market actors and producers in particular. Observations at market sites point to an imbalance in the bargaining power of traders and producers. Traders collude and jointly determine prices ahead of market day and producers have very little or no ability to negotiate prices.

    Full Text Available Taenia saginata cysticercosis is one of the zoonotic diseases that threaten food safety and food security, particularly in developing countries. A cross-sectional study was conducted to estimate the prevalence and cyst distribution in infected cattle, and food safety implications of Taenia saginata cysticercosis in Harari People’s National Regional State, eastern Ethiopia. Post-mortem inspection of carcasses and organs of slaughtered cattle in Harar Municipal Abattoir, cyst viability tests and interviews with randomly selected meat consumers were undertaken. The post-mortem inspection showed that of the 898 local zebu cattle slaughtered for human consumption and examined for the presence of cysticerci of T. saginata, 19.7% (177/898; 95% CI = 17.2–22.5 harboured at least one cyst in the muscles or organs inspected. Of the edible anatomical sites with cysticerci, shoulder muscle, liver and heart together represented 65.4%, 66.0% and 65.4% respectively of relative prevalence, total cyst count and cyst viability. These edible sites are preferred above others by local people for preparation and consumption of raw or inadequately cooked meat dishes that are locally served as kurt, kitffo and dullet. The interviews revealed that among the 300 study participants, 182 (60.7% had been infected by taeniosis at least once during the previous year and of these 99.0% had eaten raw or undercooked beef, the majority (88.3% obtained from butchers assumed to provide officially inspected meat that was fit for consumption. This indicated that existing meat inspection processes were inadequate to prevent carcasses infected with T. saginata cysticerci from reaching consumers. The high prevalence of viable cysts in the edible parts of beef together with the widespread consumption of raw or undercooked beef indicated the importance of T. saginata cysticercosis as a food safety problem in eastern Ethiopia. The promotion of policies to upgrade existing meat

    This study reports a prevalence and risk factor survey of brucellosis in small ruminants in Southern Zone of Tigray Region, Northern Ethiopia between October 2011 and April 2012 to determine the sero-prevalence of small-ruminant brucellosis and to identify associated risk factors for the occurrence of disease in small ruminants under extensive production system. Multistage random sampling was followed to select locations, flocks, and individual animals. Laboratory analysis of serum samples provided sero-prevalence estimates for flocks and geographic location. Information on risk factors at the individual and flock level was obtained by examination of individual animal and a questionnaire interview to flock owners. The overall individual animal-level sero-prevalence of brucellosis in small ruminants was 3.5 % and flock level sero-prevalence was 28.3 %, and the within-flock sero-prevalence was ranged from 0 % to 22.2 % based on the Complement Fixation Test. Multivariable logistic regression showed that the major risk factors for flock level sero-positivity were flock size and abortion history. This study showed that small-ruminant brucellosis is prevalent in the study area. Larger flock size and history of previous abortion in the flock were major risk factors identified for sero-positivity of small-ruminant brucellosis.

    Full Text Available This paper aims at evaluating the impact of productive safety net program on poverty using primary data from randomly selected 600 households in central zone of Tigrai National Regional State, Ethiopia. Propensity Score Matching and Foster-Greer-Thorbecke were used to evaluate impact of the program and poverty, respectively. The paper revealed that the program has positive and significant effect on consumption, livestock holdings, and productive assets. Moreover, impact of the program on total consumption expenditure per adult equivalent was found to be positive and significant. Using total poverty line, poverty rate was lowest among program participants (30.33% than non-participants (31.1%. Highest poverty rate was found among households headed by women (38.42% while households headed by men (23.1%. The study also revealed that the program has positive and significant effect on poverty reduction and protecting productive assets. Finally, it was recommended that female headed program participants based programs should be provided to help boost their agricultural output and reduce endemic poverty.

    Full Text Available Water shortage is one of the major constraints for production of horticultural crops in arid and semiarid regions. A field experiment was conducted to determine irrigation water and fertilizer use efficiency, growth and yield of tomato under clay pot irrigation at the experimental site of Sekota Dryland Agricultural Research Center, Lalibela, Ethiopia in 2009/10. The experiment comprised of five treatments including furrow irrigated control and clay pot irrigation with different plant population and fertilization methods, which were arranged in Randomized Complete Block Design with three replications. The highest total and marketable fruit yields were obtained from clay pot irrigation combined with application of nitrogen fertilizer with irrigation water irrespective of difference in plant population. The clay pot irrigation had seasonal water use of up to 143.71 mm, which resulted in significantly higher water use efficiency (33.62 kg m-3 as compared to the furrow irrigation, which had a seasonal water use of 485.50 mm, and a water use efficiency of 6.67 kg m-3. Application of nitrogen fertilizer with irrigation water in clay pots improved fertilizer use efficiency of tomato by up to 52% than band application with furrow or clay pot irrigation. Thus, clay pot irrigation with 33,333 plants ha-1 and nitrogen fertilizer application with irrigation water in clay pots was the best method for increasing the yield of tomato while economizing the use of water and nitrogen fertilizer in a semiarid environment.

    Full Text Available Anthropogenic factors are responsible for major land use and land cover changes (LULCC. Bale Mountain Eco-Region in Ethiopia is a biodiversity-rich ecosystem where such LULCC have occurred. The specific objectives of this study were to: (i determine which LULC types gained or lost most as a result of the observed LULCC; (ii identify the major drivers of the LULCC/deforestation; and (iii assess the approximate amount of carbon stock removed as a result of deforestation during the study period. Remote sensing and GIS were used to analyze LULCC. Landsat images acquired in 1985, 1995, 2005, and 2015 were used. Additionally, data from the Central Statistics Agency on cropland expansion, and human and livestock population growth were analyzed and correlations were made. The results showed that forest lost 123,751 ha while farmland gained 292,294 ha. Farmland and urban settlement expansion were found to be major drivers of LULCC. Aboveground carbon stock removed from forest and shrubland was more than 24 million tons. In the future, allocation of land to different uses must be based on appropriate land use policies. Integrating biodiversity and ecosystem values for each land cover as per the UN Sustainable Development Goal (UN-SDG 15.9 may be one of the mechanisms to limit unplanned expansion or invasion of one sector at the expense of another.

    Background The maternal health system in Ethiopia links health posts in rural communities (kebeles) with district (woreda) health centres, and health centres with primary hospitals. At each health post two Health Extension Workers (HEWs) assist women with birth preparedness, complication readiness, and mobilize communities to facilitate timely referral to mid-level service providers. This study explored HEWs’ and mother’s attitudes to maternal health services in Adwa Woreda, Tigray Region. Methods In this qualitative study, we trained 16 HEWs to interview 45 women to gain a better understanding of the social context of maternal health related behaviours. Themes included barriers to health services; women’s social status and mobility; and women’s perceptions of skilled birth attendant’s care. All data were analyzed thematically. Findings There have been substantial efforts to improve maternal health and reduce maternal mortality in Adwa Woreda. Women identified barriers to healthcare including distance and lack of transportation due to geographical factors; the absence of many husbands due to off-woreda farming; traditional factors such as zwar (some pregnant women are afraid of meeting other pregnant women), and discouragement from mothers and mothers-in-law who delivered their children at home. Some women experienced disrespectful care at the hospital. Facilitators to skilled birth attendance included: identification of pregnant women through Women’s Development Groups (WDGs), and referral by ambulance to health facilities either before a woman’s Expected Due Date (EDD) or if labour started at home. Conclusion With the support of WDGs, HEWs have increased the rate of skilled birth attendance by calling ambulances to transfer women to health centres either before their EDD or when labour starts at home. These findings add to the growing body of evidence that health workers at the community level can work with women’s groups to improve maternal

    We studied woodland vegetation in broad-leaved deciduous woodlands of Metema in northwestern Amhara regional state,Ethiopia to determine plant community types and species distribution patterns and their relationships with environmental variables,including altitude,pH,cation exchange capacity,electrical conductivity (EC),and moisture.We used a selective approach with a systematic sampling design.A total of 74 quadrats,each 25m × 25m at intervals of 150-200 m were sampled along the established transect lines.For herbaceous vegetation and soil data collection,five subquadrats each 1m × 1m were established at the four corners and the center of each quadrat.Three community types were identified using TWINSPAN analysis.All three community types showed high diversity (Shannon-Weiner index),the highest in community type Ⅱ at 3.55.The highest similarity coefficient was 0.49 (49%) between community types Ⅱ and Ⅲ,reflecting 0.51 (51%) dissimilarity in their species richness.The canonical correspondence ordination diagram revealed that the distribution pattern of community type Ⅰ was explained by moisture while that of community types Ⅲ and Ⅱ was explained by EC and altitude and moisture,respectively.Altitude was the most statistically significant environmental variable,followed by moisture and EC in determining the total variation in species composition and distribution patterns while pH and cation exchange capacity were non significant.In conclusion,we recommend that any intervention should take into account these three discrete community types and their environmental settings to make the intervention more successful.

    Full Text Available A systematic evaluation of food-for-work (FFW programs in Ethiopia is seriously lacking. Most of the few available reports indicate that these programs have reached very few achievements in terms of food security and reduction of poverty at large. As expressed by Holden et al. (2005, FFW programs are commonly aimed to produce or maintain potentially valuable public goods necessary to stimulate productivity and thus income growth. Natural resources management, like rural road construction, erosion control and afforestation of degraded lands can be mentioned as valuable measures which could stimulate productivity and agricultural growth. The poverty reduction and food security impact of food or cash for work activities are larger if they offer not only seasonal job opportunities to the rural community but also long term employment possibilities. This is more likely if the projects are regionally dispersed and combined with basic education. In the Ethiopian context, it was always questionable if the continuous boom in food aid (regardless of cash or food for work purposes was the solution for the long standing food insecurity and poverty crises in the country. The study discusses the efficiency of FFW programs that aimed to reduce rural poverty and ensure food security on the one hand, and the impact of the food aid on resource and time allocation of the participating households for own food production on the other. The study is based on a field research conducted at a FFW program project, in the Amhara region, Ethiopia run by the German Agency for Technical Cooperation (GTZ with the view of improving food security in the Amhara region, Ethiopia. A household theoretical model is used to analyze the sample data, whether FFW program may indeed reduce household food insecurity and/or has some crowding-out effects on labour allocation of participating households for own field production.

  9. Extension by faulting, stretching and magma intrusion in Ethiopia

    The 2001-2004 Ethiopia Afar Geoscientific Lithospheric Experiment showed that high seismic wavespeed, dense, mafic crustal intrusions exist beneath many zones of Quaternary magmatism in the Main Ethiopian rift, and that crustal thinning is minimal. From these observations, a consensus quickly emerged that extension presently occurs not by ductile stretching and brittle faulting but by magma intrusion. Striking InSAR images and accompanying seismic data from the 2005 Afar diking episode provided further compelling evidence in support of the magma assisted rifting hypothesis. Patterns of mantle seismic anisotropy, constrained by a combination of body and surface-wave analysis showed that melt intrusion likely also plays an important role in accommodating extension at greater depths in the extending plate. Evidence from further north in Afar, however, where crustal thickness decreases abruptly into the Danakil Depression, is not so easily explained by the magma assisted rifting hypothesis. Subsidence of the newly forming margin towards and below sea level, and eruption of voluminous basalt flows, is likely the result of late-stage thinning of the heavily intruded, weakened plate just before the onset of seafloor spreading. Faulting, stretching and magma intrusion are thus each important, but at different times during breakup. Combining, not isolating, these mechanisms of strain in new rifting models and appreciating how plate strength varies during rifting is essential in developing a clearer understanding of the incomplete geological record that documents continental breakup over time.

    Interspecific gene flow is common in oaks. In the Mediterranean, this process produced geographical differentiations and new species, which may have contributed to the diversification of the production of volatile terpenes in the oak species of this region. The endemic North African deciduous oak Quercus afares (Pomel) is considered to be a stabilized hybrid between the evergreen Quercus suber (L.) and the deciduous Quercus canariensis (Willd.), presumably being monoterpene and isoprene emitters, respectively. In a common garden experiment, we examined the terpene emission capacities, terpene synthase (TPS) activities and nuclear genetic markers in 52 trees of these three oak species. All but one of the Q. suber and Q. canariensis trees were found to be genetically pure, whereas most Q. afares trees possessed a mixed genotype with a predominance of Q. suber alleles. Analysis of the foliar terpene emissions and TPS activities revealed that all the Q. canariensis trees strongly produced isoprene while all the Q. suber trees were strong monoterpene producers. Quercus afares trees produced monoterpenes as well but at more variable and significantly lower rates, and with a monoterpene pattern different than that observed in Q. suber. Among 17 individuals tested, one Q. afares tree emitted only an insignificant amount of terpenes. No mixed isoprene/monoterpene emitter was detected. Our results suggest that the capacity and pattern of volatile terpene production in Algerian Q. afares populations have strongly diverged from those of its parental species and became quantitatively and qualitatively reduced, including the complete suppression of isoprene production.

    Full Text Available Across-sectional questionnaire survey and focused group discussions were conducted to characterize camel production systems and to evaluate reproductive performances of camels at their natural pastoralist management systems of Somali region. A total of 100 households were included in the study during the period of October 2012 to March 2013. About 98% of Somali pastoralists preferred camels as their first choice over other livestock species and mainly kept in the society for milk and meat production. The camel management dominating in the study areas of Somali region is traditional nomadic. Camel is one of the most important livestock for Somali pastoralists’ livelihood as a source of milk, meat and draught power. Mature female camels were dominant (54.87% in the camel herd. The ratio of male to female camel was 1:13. Mean age at first calving and calving interval were 62.16±10.44 and 23.28±3.36 months respectively. Age at first calving and calving interval can be minimized to 57±5.52 and 21.84±4.8 months by proper husbandry and health care. The mean lactation length was 11.51±1.91 months. Diseases and predators were reported as the main causes of calf mortality. In the herd dynamic simulation calf mortality rate can be reduced at least to 7% only by preventing predators attack. Diseases (66%, lack of pasture (59% and security (47% were the main constraints in camel production of the study areas. For the better productivity of camels, the major constraints such as disease problems, lack of pasture and tribal conflicts should be mitigated. Proper husbandry and health services can play significant roles in the long term improvement of camel production and productivity of the region.

    Full Text Available Dermatophytes are worldwide in distribution and dermatophytosis is a common problem in developing countries. It can occur in both sexes and all ages but the diseases are more common in school children. This study attempted to determine the prevalence and etiological agents of dermatophyte infections of hair, skin, and nail among primary school children in Harari Regional State from April to June 2015. A cross-sectional study was conducted on 428 primary school children. Skin scrapings, hair samples, and nail clippings were collected from children who showed dermatophytosis. All specimens were subjected to microscopic examination and culture. Following a meticulous collection, data was analysed using SPSS version 21. Of the 428 school children, 211 (49% male and 217 (51% female, 100 (23.4% had culture confirmed dermatophytosis and tinea capitis took the overall prevalence of 18% (77/428. Trichophyton violaceum was isolated from 43 samples, followed by Trichophyton rubrum in 24. The highest prevalence of dermatophytosis was seen in the age group 5–9 years and grade levels of 1-2 (p<0.05. As a result, this study found a high prevalence of dermatophytosis in the Harari’s Regional State school children and tinea capitis was the predominant clinical finding which needs an intervention.

    Over 35000 onshore and offshore gravity stations have been compiled in order to test isostatic models and perform geologic correlations over a large section of the Afro-Arabian shield. Ethiopia is an important part of this system because it contains the major section of the ca. 5000km Afro-Arabian rift and it includes the transition between the Arabo-Nubian-Shield (ANS) and Mozambique Belt (MB). Isostatic residual anomalies have been calculated using both Airy and Vening-Meinsez models. These anomalies outline the major Precambrian belts, the Cenozoic rifts and associated major structures. Positive residual anomalies associated with the Main Ethiopian Rift (MER) and Kenyan rift systems could be the expression of an axial intrusive body and swarms of local faults and fractures. The residual anomalies indicate relative stability in the MER and increased tectonic activity over the areas of the Red Sea, Gulf of Aden and Afar. Near-zero isostatic residuals flank the MER and Kenya rifts and are found within the Danakil Alps and some plateau regions. A series of NW-SE and E-W trending features are evident in the different isostatic residual maps. These parallel features include, from north to south, the Najid fault system, Red Sea axial zone, Melka Werer cross structure, the Anza rift and the Aswa shear zone. Additional NW-SE structures are apparent in the southern rift system, although these features are somewhat diffuse. Curvature enhanced maps are also useful for mapping fracture zones, major gravity lineaments and, in some cases, orientation of faults. Important areas from a metallogenesis point of view have been identified for further examination. The results of the qualitative interpretation form the basis of continuing three-dimensional gravity modelling and qualitative analysis that also integrates data from eastern Sudan.

    Full Text Available A cross sectional study was conducted from November, 2010 to April, 2011 in the Amhara regional state, Gondar town. The objectives of the study were to determine the prevalence of ectoparasites, determine associated risk factors and identify the most important ectoparasites species of dogs. Skin scrapings for mange mite suspected cases and collection of ectoparasites for lice, fleas and ticks was done using simple random technique. Age, sex, breed and coat color were considered as risk factors. SPSS version 17 (2004 was used for chi- square test and P-value 0.05. Ectoparasites were found more prevalent in female dogs (91.8% than males (87.1%. For age groups of 8-18 months it was 96.6% prevalent and in local breeds it was found 90.3% prevalence. In conclusion, dogs were highly exposed to ectoparasites and hence ectoparasites were serious dermatologic problems in Gondar.

Consequently, Ethiopia designed the 2011–2015, Malaria Prevention and Control Strategic Plan to fight the vector. It was discovered that most of the studies conducted on the use of insecticide-treated nets (ITNs were not in line with the strategic plan of the country. This study aimed to assess ITN ownership and utilization, and includes barriers related to its use among the target-area population at household (HH level. Materials and methods: A cross-sectional design was employed in Itang for this study. Data were collected by trained nurses through face-to-face interview and observation. A total of 845 participants were selected through multistage sampling, and the size was determined by using a single-population proportion formula. EPI Info and SPSS was used for analysis, and all necessary statistical association was computed in order to explain the outcome variable through explanatory variables of this study. Results: Among 845 HHs interviewed, 81.7% (690 had at least one ITN, while 52.3% (361 had used the ITN the night preceding the data-collection day. HH awareness of malaria prevention, number of ITNs, family size, number of family members sharing sleeping area/beds, sleeping patterns of adolescents, HH-head age, and inconvenience of using ITNs were found to be barriers to the use of ITNs in this study. Conclusion and recommendation: The study concluded that very few HHs owned ITNs and there was very low usage of ITNs. In recommendation, the regional health bureau and district health office should consider bigger nets that can accommodate family members who share the same sleeping area/bed in the area.

    Organochlorine pesticides (OCPs) and stable isotopes were measured in muscle from 4 bird and 5 fish species from the Ethiopian Rift Valley region where DDT is used for malaria control and vast agricultural activities are carried out. We investigated the bioaccumulation of OCPs such as DDTs, HCHs, chlordanes, and heptachlors between the species, and examined the potential risk posed by these compounds for bird species. Significant differences in contaminant profiles and levels were observed within the species. Levels of total OCPs ranged from 3.7 to 148.7 μg/g lipid in bird and 0.04 to 10.9 μg/g lipid in fish species. DDTs were the predominant contaminant, and a positive relationship between δ(15)N and ΣDDT concentrations was found. The main DDT metabolite, p,p'-DDE was the most abundant and significantly greater concentrations in bird species (up to 138.5 μg/g lipid), which could have deleterious effects on survival and/or reproduction of birds.

    A cross sectional study of small ruminant mange mites was conducted from November 2011 to April 2012 on a total of 324 sheep and 680 goats, to determine the prevalence of mange mites in sheep and goats, identifying the major species of mite and to determine the potential risk factors significantly predicting the disease. The result showed an overall mange mite prevalence of 7.5 % (95 % CI 5.5-9.5) in goats and 1.2 % (95 % CI 0.5-1.9) in sheep. The mites identified were Sarcoptes and Demodex in goats and Sarcoptes and Psoroptes in sheep. The prevalence of mange mites was significantly higher in goats than in sheep (χ(2) = 16.636, P = 0.000). There was higher prevalence of mange mites in poor body condition than good body condition sheep and goats and the difference was statistically significant (χ(2) = 5.513, P = 0.019 in sheep and χ(2) = 141.85, P = 0.000 in goats). But age and sex of the host animals and agro climates were not statistically significant predictors of prevalence of mange mite. This study demonstrated that mange mites are among the major parasitic health problems of shoats in Eastern Amhara region that require urgent control intervention.

    Full Text Available A cross sectional study was conducted on 906 apparently healthy camels slaughtered at Akaki and Metehara abattoirs to investigate the pathology of camel tuberculosis (TB and characterize its causative agents using postmortem examination, mycobacteriological culturing, and multiplex polymerase chain reaction (PCR, region of difference-4 (RD4-based PCR and spoligotyping. The prevalence of camel TB was 10.04% (91/906 on the basis of pathology and it was significantly higher in females (χ(2 = 4.789; P = 0.029. The tropism of TB lesions was significantly different among the lymph nodes (χ(2 = 22.697; P = 0.002 and lung lobes (χ(2 = 17.901; P = 0.006. Mycobacterial growth was observed in 34% (31/91 of camels with grossly suspicious TB lesions. Upon further molecular characterization using multiplex PCR, 68% (21/31 of the colonies showed a positive signal for the genus Mycobacterium, of which two were confirmed Mycobacterium bovis (M. bovis by RD4 deletion typing. Further characterization of the two M. bovis at strains level revealed that one of the strains was SB0133 while the other strain was new and had not been reported to the M. bovis database prior to this study. Hence, it has now been reported to the database, and designated as SB1953. In conclusion, the results of the present study have shown that the majority of camel TB lesions are caused by mycobacteria other than Mycobacterium tuberculosis complex. And hence further identification and characterization of these species would be useful towards the efforts made to control TB in camels.

  20. Tectonics of the Afar Depression: A review and synthesis

    Beyene, Alebachew; Abdelsalam, Mohamed G.

    2005-01-01

    This article outlines geomorphological and tectonic elements of the Afar Depression, and discusses its evolution. A combination of far-field stress, due to the convergence of the Eurasian and Arabian plates along the Zagros Orogenic Front, and uplift of the Afar Dome due to a rising mantle plume reinforced each other to break the lithosphere of the Arabian-Nubian Shield. Thermal anomalies beneath the Arabian-Nubian Shield in the range of 150 °C-200 °C, induced by a rising plume that mechanically and thermally eroded the base of the mantle lithosphere and generated pulses of prodigious flood basalt since ˜30 Ma. Subsequent to the stretching and thinning the Afar Dome subsided to form the Afar Depression. The fragmentation of the Arabian-Nubian Shield led to the separation of the Nubian, Arabian and Somalian Plates along the Gulf of Aden, the Red Sea and the Main Ethiopian Rift. The rotation of the intervening Danakil, East-Central, and Ali-Sabieh Blocks defined major structural trends in the Afar Depression. The Danakil Block severed from the Nubian plate at ˜20 Ma, rotated anti-clockwise, translated from lower latitude and successively moved north, left-laterally with respect to Nubia. The westward propagating Gulf of Aden rift breached the Danakil Block from the Ali-Sabieh Block at ˜2 Ma and proceeded along the Gulf of Tajura into the Afar Depression. The propagation and overlap of the Red Sea and the Gulf of Aden along the Manda Hararo-Gobaad and Asal-Manda Inakir rifts caused clockwise rotation of the East-Central Block. Faulting and rifting in the southern Red Sea, western Gulf of Aden and northern Main Ethiopian Rift superimposed on Afar. The Afar Depression initiated as diffused extension due to far-field stress and area increase over a dome elevated by a rising plume. With time, the lithospheric extension intensified, nucleated in weak zones, and developed into incipient spreading centers.

  1. The development of extension and magmatism in the Red Sea rift of Afar

    Despite the importance of continental breakup in plate tectonics, precisely how extensional processes such as brittle faulting, ductile plate stretching, and magma intrusion evolve in space and time during the development of new ocean basins remains poorly understood. The rifting of Arabia from Africa in the Afar depression is an ideal natural laboratory to address this problem since the region exposes subaerially the tectonically active transition from continental rifting to incipient seafloor spreading. We review recent constraints on along-axis variations in rift morphology, crustal and mantle structure, the distribution and style of ongoing faulting, subsurface magmatism and surface volcanism in the Red Sea rift of Afar to understand processes ultimately responsible for the formation of magmatic rifted continental margins. Our synthesis shows that there is a fundamental change in rift morphology from central Afar northward into the Danakil depression, spatially coincident with marked thinning of the crust, an increase in the volume of young basalt flows, and subsidence of the land towards and below sea-level. The variations can be attributed to a northward increase in proportion of extension by ductile plate stretching at the expense of magma intrusion. This is likely in response to a longer history of localised heating and weakening in a narrower rift. Thus, although magma intrusion accommodates strain for a protracted period during rift development, the final stages of breakup are dominated by a phase of plate stretching with a shift from intrusive to extrusive magmatism. This late-stage pulse of decompression melting due to plate thinning may be responsible for the formation of seaward dipping reflector sequences of basalts and sediments, which are ubiquitous at magmatic rifted margins worldwide.

    northwestward. Concurrently, such lithospheric cracks are forced to jump northward, such that the plate boundary remains inside the regional N-S necking zone. Changes of obliquity between the directions of overall and local propagation may account for different segmentation patterns, a small angle promoting long, en échelon subrifts, and a high-angle, smaller, nested, "subrifts within subrifts." The propagation mechanism is thus similar, whether in oceanic or continental lithosphere, the principal change being the overall propagation path, here governed by thickness changes rather than by the geometry in map view as previously inferred for the rest of the Aden ridge. Finally, because the same mechanism has led rifting along the Red Sea to propagate southward and jump to the western edge of Afar, the Arabia-Somalia and Arabia-Nubia plate boundaries tips have missed each other and keep overlapping further, leading to strain transfer by large-scale bookshelf faulting.

    The Afar Depression (East Africa) connects all three continental plates of Arabia, Somalia and Nubia plates. For over 20 Ma, the divergent motion of these plates has led to the formation of large normal faults building tall scarps between the high plateaus and the depression, and the development of large basins and an incipient seafloor spreading along a series of active volcano-tectonic rift segments within the depression. The space-time evolution of the active surface deformation over the whole Afar region remains uncertain. Previous tectonic and geodetic studies confirm that a large part of the current deformation is concentrated along these segments. However, the amount of extension accommodated by other non-volcanic basins and normal faulting remains unclear, despite significant micro-seismic activity. Due to the active volcanism, large transient displacements related to dyking sequence, notably in the Manda Hararo rift (2005-2010), increase the difficulty to characterize the deformation field over simple time and space scales. In this study, we attempt to obtain a complete inventory of the deformation within the whole Afar Depression and to understand the associated phenomena, which occurred in this singular tectonic environment. We study in particular, the behavior of the structures activated during the post-dyking stage of the rift segments. For this purpose, we conduct a careful processing of a large set of SAR ENVISAT images over the 2004-2010 period, we also use previous InSAR results and GPS data from permanent stations and from campaigns conducted in 1999, 2003, 2010, 2012 within a GPS network particularly dense along the Asal-Ghoubbet segment. In one hand, in the western part of Afar, the far-field response of the 2005-2010 dyke sequence appears to be the dominant surface motion on the mean velocity field. In an other hand, more eastward across the Asal-Ghoubbet rift, strong gradients of deformation are observed. The time series analysis of both In

    Leguminous trees play an important role in agroforestry in Ethiopia, but studies of their rhizobial symbionts are scarce. In earlier studies, we surveyed natural nodulation of native leguminous trees growing in different agro-ecological zones in Southern Ethiopia, isolated 400 rhizobia, and characterized them based on different phenotypic and genotypic methods. In the present study we characterized 18 strains belonging to the genus Mesorhizobium, isolated from nodules of Acacia abyssinica, A. senegal, A. tortilis and Sesbania sesban. Phylogenetic analysis of nearly full-length 16S rRNA gene grouped the test strains into three distinct clades separated from all currently recognized Mesorhizobium species. Three divergent strains formed separate branches while the other 15 strains formed three distinct groups, genospecies I-III. Grouping of the isolates under study based on the house-keeping genes recA, gyrB, rpoB and gltA were consistent and in agreement with that of 16S rRNA. Similarly phylogenetic relationships based on the symbiosis-related genes nodC, nodA and nifH were generally similar to those shown by the core genes, suggesting that these Acacia and Sesbania symbionts have a long history of separate evolution within Mesorhizobium. Cross inoculation experiments demonstrated a large variation in the ability of the test strains to elicit effective nodules. The Sesbania isolates, occupying a distinct clade in the nodC phylogenetic tree, formed effective nodules only with this host legume. The study strongly suggests that this collection of Mesorhizobium strains comprises several new species, and also indicates the role of the symbiotic genes in determining the host range of these bacteria.

    Full Text Available Purpose: The purpose of this study was to assess the degree of adherence of health care facility to World Health Organization health facility indicators in selected health care facilities of Amhara Region, Northwest Ethiopia. Methods: A cross sectional study was conducted among randomly selected health care facilities of Amhara region from March 01 to 15, 2014. Data was collected by interview and observation using structured questionnaire and check list respectively. Ethical clearance was obtained from the ethics review committee of Amhara regional state health bureau. The data was checked for completeness and consistency, cleared, coded, and entry and analysis was done by using SPSS (version 16. Results: The percentage availability of key essential drugs was found to be 73.05%, availability of Essential Drug List (EDL, Standard Treatment Guidelines (STG, drug formulary and average stock out duration were 75%, 87.5% 75% and 34 days respectively. Conclusion: The study revealed that evaluation of the patterns of drug use based on World Health Organization (WHO facility indicators was not satisfactory. So there is a need for managerial and educational intervention to improve rational drug use and thereby need to improve’ availability of essential drug list, standard treatment guidelines, drug formulary in order to access unbiased information for health care providers and also to prevent stock out of key essential drugs.

  6. Nature of the crust under Afar: new igneous, not thinned continental

    Thinned continental crust is considered absent from beneath Afar, except for isolated remnants such as comprise the Danakil Block. The Ethiopian Plateau sialic crust thins abruptly across the plateau-Afar margin to abut new igneous crust under Afar, generated during the early development of the Red Sea basin. Analyses of stretching and sea-floor spreading amounts elsewhere in the Red Sea and Gulf of Aden basins are employed to support this concept. The dual layering of the Afar crust, and the similarity of P-wave velocities in these layers to velocities in sialic crust, lead to the proposal that new continental crust can be generated at magmatic rift zones.

    The experiment was conducted at Alamata Agricultural Research Center, Ethiopia using 20 Afar rams with an initial body weight (BW) of 18.2 +/- 1.76 (mean +/- SD) kg. The objectives were to study the effect of supplementation with concentrate mix consisting of wheat bran (WB), noug seed cake (NSC) and sesame seed cake (SSC) at the ratio of 2:1:1 on dry matter (DM) basis, respectively on feed intake, digestibility, BW gain and carcass parameters of Afar rams fed tef (Eragrostis tef) straw basal diet. The experiment was arranged with four treatments and five replications in a randomized complete block design. The treatments included feeding sole tef straw (T1, control), and daily supplementation with the concentrate mix offered at 150 (T2, low), 250 (T3, medium) and 350 (T4, high) g DM per head. Total DM intake, crude protein (CP) digestibility, daily BW gain (P mix supplementation. Moreover, the medium level of supplementation did not substitute tef straw intake. Therefore, it is concluded that the medium level of concentrate mix supplement maintained the utilization of the roughage feed and resulted in better carcass parameters.

    Full Text Available Abstract Traditional medicine (TM has been a major source of health care in Ethiopia as in most developing countries around the world. This survey examined the extent and factors determining the use of TM and medicinal plants by Berta community. One thousand and two hundred households (HHs and fourteen traditional healers were interviewed using semi-structured questionnaires and six focused group discussions (FGDs were conducted. The prevalence of the use of TM in the two weeks recall period was 4.6%. The HH economic status was found to have a significant effect while the educational level and age of the patients have no effect either on the care seeking behavior or choice of care. Taking no action about a given health problem and using TM are common in females with low-income HHs. Forty plant species belonging to 23 families were reported, each with local names, methods of preparation and parts used. This study indicates that although the proportion of the population that uses TM may be small it is still an important component of the public health care in the study community as complementary and alternative medicine.

    Kinematics of divergent boundaries and Rift-Rift-Rift junctions are classically studied using long-term geodetic observations. Since significant magma-related displacements are expected, short-term deformation provides important constraints on the crustal mechanisms involved both in active rifting and in transfer of extensional deformation between spreading axes. Using InSAR and GPS data, we analyse the surface deformation in the whole Central Afar region in detail, focusing on both the extensional deformation across the Quaternary magmato-tectonic rift segments, and on the zones of deformation transfer between active segments and spreading axes. The largest deformation occurs across the two recently activated Asal-Ghoubbet (AG) and Manda Hararo-Dabbahu (MH-D) magmato-tectonic segments with very high strain rates, whereas the other Quaternary active segments do not concentrate any large strain, suggesting that these rifts are either sealed during interdyking periods or not mature enough to remain a plate boundary. Outside of these segments, the GPS horizontal velocity field shows a regular gradient following a clockwise rotation of the displacements from the Southeast to the East of Afar, with respect to Nubia. Very few shallow creeping structures can be identified as well in the InSAR data. However, using these data together with the strain rate tensor and the rotations rates deduced from GPS baselines, the present-day strain field over Central Afar is consistent with the main tectonic structures, and therefore with the long-term deformation. We investigate the current kinematics of the triple junction included in our GPS data set by building simple block models. The deformation in Central Afar can be described by adding a central microblock evolving separately from the three surrounding plates. In this model, the northern block boundary corresponds to a deep EW-trending trans-tensional dislocation, locked from the surface to 10-13 km and joining at depth the

    Staphylococcal food poisoning (SFP) is an important foodborne disease worldwide, and milk and milk products are commonly associated with SFP outbreaks. The objectives of this study were to investigate the distribution of staphylococcal enterotoxin (se) genes in Staphylococcus aureus from raw cow's milk and milk products and to assess their genetic background with the spa typing method. Of the 549 samples (297 bulk milk and 162 milk product samples) collected from Tigray region, Northern Ethiopia, 160 (29.1%) were positive for S. aureus, of which 82 (51%) were found to harbor se genes by a modified multiplex PCR. Nine se genes were identified: sea (n = 12), seb (n = 3), sec (n = 3), sed(n = 4), seg (n = 49), seh (n = 2), sei (n = 40), sej (n = 1), and tsst-1 (n = 24). The classical type of genes accounted for 27%. Of the 82 enterotoxigenic isolates, 41.5 and 12.4% harbored two or more se genes, respectively. The highest gene association was observed between sei and seg, whereas sea and seb were always found together with the new types of se genes. Altogether, 18 genotypes of toxin genes were identified, and 33% of the samples contained > 5 log CFU ml(-1) S. aureus. spa typing identified 22 spa types and three novel spa sequences, which showed the high genetic diversity of the isolates. No apparent relationship was observed between spa type and se genes. Of the 25 spa types, 13 (52%) were from raw milk, 3 (12%) from milk products, and 9 (36%) from both types of sample. Types t314 (20.7%,n = 17), t458 (18.3%, n = 15), and t6218 (9.8%, n= 8) were the most common spa types identified and were widely distributed in three of the eight studied localities. This is the first study from the Tigray region to report the high distribution of enterotoxigenic S. aureus with a diversified genetic background from dairy food. The study may provide valuable data for microbial food safety risk assessment, molecular epidemiology, and phylogenetic studies of S. aureus in Ethiopia.

    This paper presents the Quaternary sequence of the Mieso area of Central-East Ethiopia, located in the piedmont between the SE Ethiopian Escarpment and the Main Ethiopian Rift-Afar Rift transition sector.In this region, a piedmont alluvial plain is terraced at þ25 m above the two main fluvial courses, the Mieso and Yabdo Rivers. The piedmont sedimentary sequence is divided into three stratigraphic units separated by unconformities. Mieso Units I and II contain late Acheulean assemblages and a weakly consolidated alluvial sequence, consisting mainly of fine sediments with buried soils and, to a lesser degree, conglomerates. Palaeo-wetland areas were common in the alluvial plain, represented by patches of tufas, stromatolites and clays. At present, the piedmont alluvial surface is preserved mainly on a dark brown soil formed at the top of Unit II. Unit III corresponds to a fluvial deposit overlying Unit II, and is defined by sands, silty clays and gravels, including several Later Stone Age (LSA) occurrences. Three fine-grained tephra levels are interbedded in Unit I (tuffs TBI and TA) and II (tuff CB), and are usually spatially-constrained and reworked. Argon/argon (40Ar/39Ar) dating from tuff TA, an ash deposit preserved in a palustrine environment, yielded an age of 0.212 ± 0.016 Ma (millions of years ago). This date places thetop of Unit I in the late Middle Pleistocene, with Acheulean sites below and above tuff TA. Regional correlations tentatively place the base of Unit I around the Early-Middle Pleistocene boundary, Unit II inthe late Middle Pleistocene and within the Late Pleistocene, and the LSA occurrences of Unit III in the LatePleistoceneeHolocene.

    Full Text Available Abstract Background In Ethiopia, malaria transmission is seasonal and unstable, with both Plasmodium falciparum and Plasmodium vivax endemic. Such spatial and temporal clustering of malaria only serves to underscore the importance of regularly collecting up-to-date malaria surveillance data to inform decision-making in malaria control. Cross-sectional school-based malaria surveys were conducted across Oromia Regional State to generate up-to-date data for planning malaria control interventions, as well as monitoring and evaluation of operational programme implementation. Methods Two hundred primary schools were randomly selected using a stratified and weighted sampling frame; 100 children aged five to 18 years were then randomly chosen within each school. Surveys were carried out in May 2009 and from October to December 2009, to coincide with the peak of malaria transmission in different parts of Oromia. Each child was tested for malaria by expert microscopy, their haemoglobin measured and a simple questionnaire completed. Satellite-derived environmental data were used to assess ecological correlates of Plasmodium infection; Bayesian geostatistical methods and Kulldorff's spatial scan statistic were employed to investigate spatial heterogeneity. Results A total 20,899 children from 197 schools provided blood samples, two selected schools were inaccessible and one school refused to participate. The overall prevalence of Plasmodium infection was found to be 0.56% (95% CI: 0.46-0.67%, with 53% of infections due to P. falciparum and 47% due to P. vivax. Of children surveyed, 17.6% (95% CI: 17.0-18.1% were anaemic, while 46% reported sleeping under a mosquito net the previous night. Malaria was found at 30 (15% schools to a maximum elevation of 2,187 metres, with school-level Plasmodium prevalence ranging between 0% and 14.5%. Although environmental variables were only weakly associated with P. falciparum and P. vivax infection, clusters of infection

    Despite increasing international attention to child marriage and its negative health and social consequences, little is known about the knowledge and beliefs of individuals who are in control of negotiating children's marriages and of the social context in which these individuals function. Using data from a 2007 cross-sectional household survey and multilevel logistic regression models, this paper examined the associations of communication exposure and measures of social influence with knowledge of marriage legislation, perceptions that marriage before age 18 was "too early", and beliefs in daughters' rights to individual marriage choice among parents/guardians in Amhara Region, Ethiopia. The study found that mass media and interpersonal communication exposure were positively associated with all outcomes. The influence of communication exposure on knowledge of the legal minimum age at marriage and the perception that marriage before 18 was "too early" varied significantly across communities. Community pressure to stop child marriages and awareness of marriage law enforcement were positively associated with endorsing daughters' rights to choose their marriage age and partner. Perceived social norms regarding early marriage, normative beliefs and perceived benefits of delayed marriage were at least as important as communication exposure for endorsing daughters' rights to marriage choice. Gender and education differences were detected. The findings imply that child marriage-prevention programs should diversify information channels, reinforce perceived advantages of delayed marriage, and adopt a social influence perspective.

    Full Text Available Following recent large scale-up of malaria control interventions in Ethiopia, this study aimed to compare ownership and use of long-lasting insecticidal nets (LLIN, and the change in malaria prevalence using two population-based household surveys in three regions of the country. Each survey used multistage cluster random sampling with 25 households per cluster. Household net ownership tripled from 19.6% in 2006 to 68.4% in 2007, with mean LLIN per household increasing from 0.3 to 1.2. Net use overall more than doubled from 15.3% to 34.5%, but in households owning LLIN, use declined from 71.7% to 48.3%. Parasitemia declined from 4.1% to 0.4%. Large scale-up of net ownership over a short period of time was possible. However, a large increase in net ownership was not necessarily mirrored directly by increased net use. Better targeting of nets to malaria-risk areas and sustained behavioural change communication are needed to increase and maintain net use.

    Background. Young people constitute a large number of population worldwide, and majority of this population group lives in developing countries. They are at high risk of engaging in risky sexual behaviors. These risk sexual behaviors predispose youths to several sexual and reproductive health problems like STIs, HIV, unwanted pregnancy, and abortion. So, this study was conducted to assess the magnitude of risky sexual behaviors and associated factors among Jiga high school and preparatory school students, northwest Ethiopia. Methodology. Institutional based cross-sectional study design was conducted among Jiga town high school and preparatory school students. A total of 311 students were included in the study. Systematic random sampling method was used to select study participants. Data was entered using EpiData version 3.1 and it was exported to SPSS version 22 for further analysis. Descriptive analysis and bivariate and multivariate analysis were also calculated to determine factors associated with risky sexual behavior. Result. Forty-eight (16%) of respondents reported that they had sexual intercourse. From those who start sex, 44 (14.7%) were involved in risky sexual behavior which could predispose them to sexual and reproductive health problems. More than half, 27 (56.3%), of respondents first sexual intercourse was before their eighteenth birthday. The mean age and SD of fist sexual initiation were 17.2 years old and 1.35 years, respectively. Factors associated with risky sexual behavior include respondents between the ages of 20 and 23 (AOR: 5, 95%, CI: 1.59–15.98), drinking alcohol (AOR: 2.48, 95% CI: 1.13–5.41), and having poor knowledge towards HIV/AIDS (AOR: 4.53, 95%, CI: 2.06–9.94). Conclusion. A large number of in-school youths are involved in risky sexual behaviors like early sexual initiation, having multiple sexual partners, inconsistence use of condom, and having sex with high risk partner (CSWs). Age of respondents, alcohol drinking, and

    Uplifts caused by magma intrusion have been observed and mapped since the pioneering work of von Buch two hundred years ago. Von Buch's "Craters of elevation theory", developed in the Auvergne and Canaries, was, unfortunately, discredited and mostly forgotten until recent work has shown that the forced folds mapped in seismic sections in sedimentary basins are the same type of feature. Also, these magmatic bulges are being found on an increasing number of volcanoes. The Danakil region of Ethiopia contains a superb range of forced folds with craters of elevation, which we have mapped using Google Earth and other satellite imagery, and some ground truthing. This preliminary work provides a geological map that is inspired from the 1970 Barberi and Vallet map, and which sets out in detail the structure and lava flow units of this area. We describe the main structures of each uplift, and suggest a preliminary general structural evolutionary pattern that provides a model for future research. This work has been untertaken by a group from multiple universities sharing interpretations and data in an open format. We aim to continue this work to study these superb geological features. Their superb nature and preservation is such that we would also press for them to be made a geoheritage reserve of global importance: Either a Geopark or a World Heritage site.

    Tuberculosis (TB) is one of the most serious public health challenges in Ethiopia. Indeed, Ethiopia ranks 7th among 22 countries with a high burden of TB worldwide. Both pulmonary TB and extrapulmonary TB (EPTB) are issues of concern. Ethiopia ranks 3rd in terms of the number of EPTB patients worldwide, with TB lymphadenitis (TBL) being the most common. According to the World Health Organization's Global TB Report 2009, the estimated number of TB patients in Ethiopia was 314,267 in 2007, with an estimated incidence rate of 378 patients per 100,000 population. Furthermore, 36% patients suffered from EPTB, with TBL accounting for 80% of these patients. In Ethiopia, pathological services, culture, and drug susceptibility testing for mycobacterium species are not available as routine tests, not even for cases with suspected infection by drug-resistant strains. Therefore, the management of multidrug-resistant (MDR) TB in Ethiopia is currently unsatisfactory. Against this background, a high index of clinical doubt and timely use of diagnostic methods, prompt confirmation of diagnosis, and early initiation of specific anti-TB treatment are the key factors for the successful management of MDR-TB and TBL in Ethiopia.

    Background:There is growing evidence suggesting that diabetes mellitus (DM) affects disease presentation and treatment outcome in tuberculosis (TB) patients.This study aimed at investigating the role of DM on clinical presentations and treatment outcomes among newly diagnosed TB patients.Methods:A prospective cohort study was conducted in South-Eastern Amhara Region,Ethiopia from September 2013 till March 2015.Study subjects were consecutively recruited from 44 randomly selected health facilities in the study area.Participants were categorized into two patient groups,namely,patients with TB and DM (TBDM) and TB patients without DM (TBNDM).Findings on clinical presentations and treatment outcomes were compared between the two patient groups.Cox proportional hazard regression analysis was applied to identify factors associated with death.Results:Out of 1314 TB patients enrolled in the study,109 (8.3 %) had coexisting DM.TBDM comorbidity [adjusted hazard ratio (AHR) 3.96;95 % confidence interval (C.l.) (1.76-8.89)],and TB coinfection with human immunodeficiency virus (HIM) [AHR 2.59;95 % C.l.(1.21-5.59)] were associated with increased death.TBDM and TBNDM patients did not show significant difference in clinical symptoms at baseline and during anti-TB treatment period.However,at the 2nd month of treatment,TBDM patients were more symptomatic compared to patients in the TBNDM group.Conclusions:The study showed that DM is associated with increased death during TB treatment.DM has no association with clinical presentation of TB except at the end of the intensive phase treatment.Routine screening of TB patients for DM is recommended for early diagnosis and treatment of patients with TBDM comorbidity.

    Full Text Available Background:Tuberculosis is a leading cause of death among people living with human immunodeficiency virus. In sub-Saharan Africa, tuberculosis accounts for more than 78% of all deaths among people with human immunodeficiency virus.Objectives:To assess tuberculosis treatment outcome and the associated factors in adult tuberculosis/human immunodeficiency virus co-infected patients in four public hospitals of eastern and southern zone of Tigray region, Ethiopia.Methodology:Institution based cross-sectional study design was used to examine secondary data from tuberculosis/human immunodeficiency virus co-infected patients attending four public hospitals of eastern and southern zone of Tigray, from January 2009 to August 2011. Systematic random sampling technique was used to select individual patient cards from the respective hospitals. Univariate analysis and multivariate logistic regression modeling was used to assess the impact of each variable in predicting treatment outcome.Results:Out of 342 patients included, 199 (58.2% patients completed treatment, 43 (12.6% patients were cured, 88 (25.7% died, 7 (2% defaulted, and 5 (1.5% patients failed treatment. Treatment success rate was around 71%. In the multivariate logistic regression analysis the factors that were strongly associated with unfavorable tuberculosis treatment outcomes were WHO stage IV (AOR = 3.2, CI = 1.58-6.82, p-value = 0.001, age greater than 45 years (AOR = 6.08, CI = 2.28-16.23 and baseline CD4 count less than 200 cells/L (AOR = 6.19, CI = 2.28-16.89, p-value = 0.001.Conclusion:The rate of treatment success in this study was lower than the rate newly recommended by WHO. Therefore, efforts should be undertaken to improve treatment success rates of both diseases.

    Since the Industrial Revolution, modern agriculture has transformed from a net energy supplier to a net energy user, via the extensive use fossil fuels -that substituted solar energy inputs- and petroleum derivative products (fertilizers) (Pimentel and Pimentel 2008; Woods et al. 2010). This condenses a significant overview of agricultural energetics, especially for economies set on their first stage of development, growth and economic diversification, such as Ethiopia. Ethiopia is the Blue Nile's most upstream country, constituting a very sensitive hydroclimatic area. Since 2008, Ethiopian agriculture experiences a boost in energy use and agricultural value-added per worker, due to the rapid introduction of oil-fueled agricultural machinery that increased productivity and allowed crop diversification. Agriculture in Ethiopia accounts for ~82% of its total exports, ~45% of its Gross Domestic Product (GDP) and ~75% of its total labor force. In addition, Ethiopia's agricultural sector is equipped with a set of new financial tools to deal with hydroclimatic extremes, like the 1983-85 droughts that deteriorated its crop output, causing a devastating famine. In fact, Ethiopia's resilience from the (most) recent drought (2015-16) has been remarkable. These facts signify that Ethiopia satisfies the necessary conditions to become a regional agritrade gravity center in the Blue Nile, granted that the dispersion of agricultural trade comprises a primary tool for securing food supply. As gravity equations have been used to model global trade webs (Tinbergen 1962), similar principles may apply to agritrade as well, for identifying emergent topological structures and supply chains. By examining the relation between energy inputs in agriculture with crop diversification and value-added chains of Ethiopia's agritrade, we could extract accurate information on the importance of energy for the country's agroeconomic complexity and regionalization trend across its first stages of

    This brief article looks at the intersection of climate, land cover/land use, and population trends in the world's most food insecure country, Ethiopia. As a result of warming in the Indian and Western Pacific oceans, Ethiopia has experienced substantial drying over the past 20 years. We intersect the spatial pattern of this drying with high resolution climatologies, maps of agricultural expansion, population data, and socioeconomic livelihoods information to suggest that the coincidence of drying and agricultural expansion in south-central Ethiopia is likely adversely affecting a densely populated region with high levels of poverty and low wage levels.

    Full Text Available Aim: The objective of this study was to investigate prevalence of gastrointestinal parasites and Cryptosporidium species in extensively managed pigs in Mekelle and urban areas of southern zone of Tigray Region, Ethiopia during June - September, 2012. Material and methods: Seven hundred fourteen pigs of different ages and sexes were selected for fecal sample collection. Fecal samples were collected from the rectum of pigs with strict sanitation. A total of 25 soil samples were also collected from backyards of pig pens using clean zipped plastic bags. Both fecal and soil samples were examined for eggs and cysts of GIT parasites by flotation and sedimentation techniques. Modified Ziehl – Neelsen technique was used to examine oocysts of Cryptosporidium species from 276 randomly selected fecal samples. Results: Out of 714 pigs examined through flotation and sedimentation, 27.3% were infected by at least one gastrointestinal parasite. Ascaris suum (25.9% was the most prevalent parasite followed by Fasciola hepatica (1.8%, Eimeria spp. (1.7% and Trichuris suis (0.3%. There was no significant association between sex and prevalence of parasites ÷2[df 1] = 1.921; P=0.166. Contrary to this, age of pigs had effect on prevalence of parasites ÷2[df 2] = 8.376; P=0.015. About 7% of pigs examined were positive for oocysts of Cryptosporidium spp. Moreover, 72% of the soil samples found to be contaminated with eggs of Ascaris spp. in the study area. Apart from causing morbidity in the infected pigs, the potential of Ascaris of pigs to infect man and vice versa together with poor environmental hygiene, may complicate the epidemiology and control of Ascariasis in the study areas. Extensively managed pigs may also act as potential reservoirs for zoonoses of Cryptosporidium species. Conclusion: It is concluded that further investigations are crucial on molecular characterization of Ascaris and Cryptosporidium isolates of extensively managed pigs to determine the

    Full Text Available Abstract Background There has been recent large scale-up of malaria control interventions in Ethiopia where transmission is unstable. While household ownership of long-lasting insecticidal nets (LLIN has increased greatly, there are concerns about inadequate net use. This study aimed to investigate factors associated with net use at two time points, before and after mass distribution of nets. Methods Two cross sectional surveys were carried out in 2006 and 2007 in Amhara, Oromia and SNNP regions. The latter was a sub-sample of the national Malaria Indicator Survey (MIS 3R. Each survey wave used multi-stage cluster random sampling with 25 households per cluster (224 clusters with 5,730 households in Baseline 2006 and 245 clusters with 5,910 households in MIS 3R 2007. Net ownership was assessed by visual inspection while net utilization was reported as use of the net the previous night. This net level analysis was restricted to households owning at least one net of any type. Logistic regression models of association between net use and explanatory variables including net type, age, condition, cost and other household characteristics were undertaken using generalized linear latent and mixed models (GLLAMM. Results A total of 3,784 nets in 2,430 households were included in the baseline 2006 analysis while the MIS 3R 2007 analysis comprised 5,413 nets in 3,328 households. The proportion of nets used the previous night decreased from 85.1% to 56.0% between baseline 2006 and MIS 3R 2007, respectively. Factors independently associated with increased proportion of nets used were: LLIN net type (at baseline 2006; indoor residual spraying (at MIS 3R 2007; and increasing wealth index at both surveys. At both baseline 2006 and MIS 3R 2007, reduced proportion of nets used was independently associated with increasing net age, increasing damage of nets, increasing household net density, and increasing altitude (>2,000 m. Conclusion This study identified

    Continental rupture processes under mantle plume influence are still poorly known although extensively studied. The Afar plume has been largely investigated in Ethiopia to study early stages of continental break-up. Here we imaged the lithospheric structure of western continental Yemen to evaluate the role of the Afar plume on the evolution of the continental margin and its extent towards the East. A part of the YOCMAL project (YOung Conjugate MArgins Laboratory) permitted the deployment of twenty-three broadband stations in Yemen (from 2009 to 2010). Using a classical teleseismic tomography (Aki et al., 1974) on these stations together with a permanent GFZ station, we image the relative velocity variations of P-waves in the crust and lithosphere down to 300 km depth, with a maximum lateral resolution of about ~20 km. The model thus obtained shows (1) a dramatic and localized thinning of the crust in the vicinity of the Red Sea and the Gulf of Aden (2) the presence of magmatic underplating related to seaward dipping reflectors under those two volcanic margins (3) two granitic syn-rift intrusions on the border of the great escarpment (4) a low velocity anomaly in which with evidence of partial melting, just below thick Oligocene trapps series and other volcanic events (from 15 Ma to present). This low velocity anomaly could correspond to an abnormally hot mantle and could be responsible for dynamic topography and recent magmatism in western Yemen. (5) Finally, we infer the presence of hot material under the Southwestern corner of Yemen that could be related to Miocene volcanism in Jabal an Nar.

    Full Text Available Driven by various initiatives and international policy processes, the concept of Forest Landscape Restoration, is globally receiving renewed attention. It is seen internationally and in national contexts as a means for improving resilience of land and communities in the face of increasing environmental degradation through different forest activities. Ethiopia has made a strong voluntary commitment in the context of the Bonn Challenge—it seeks to implement Forest Landscape Restoration (FLR on 15 million ha. In the context of rural Ethiopia, forest establishment and restoration provide a promising approach to reverse the widespread land degradation, which is exacerbated by climate change and food insecurity. This paper presents an empirical case study of FLR opportunities in the Amhara National Regional State, Ethiopia’s largest spans of degraded and barren lands. Following the Restoration Opportunity Assessment Methodology, the study categorizes the main types of landscapes requiring restoration, identifies and prioritizes respective FLR options, and details the costs and benefits associated with each of the five most significant opportunities: medium to large‐scale afforestation and reforestation activities on deforested or degraded marginal land not suitable for agriculture, the introduction of participatory forest management, sustainable woodland management combined with value chain investments, restoration of afro‐alpine and sub‐afro‐alpine areas and the establishment of woodlots.

    The livestock subsector has an enormous contribution to Ethiopia's national economy and livelihoods of many Ethiopians. The subsector contributes about 16.5% of the national Gross Domestic Product (GDP) and 35.6% of the agricultural GDP. It also contributes 15% of export earnings and 30% of agricultural employment. The livestock subsector currently support and sustain livelihoods for 80% of all rural population. The GDP of livestock related activities valued at 59 billion birr. Ethiopian livestock population trends, distribution and marketing vary considerably across space and time due to a variety of reasons. This study was aimed to assess cattle and shoat population growth trend, distribution and their access to market. Regression analysis was used to assess the cattle and shoat population growth trend and Geographic Information Systems (GIS) techniques were used to determine the spatial distribution of cattle and shoats, and their relative access to market. The data sets used are agricultural census (2001/02) and annual CSA agricultural sample survey (1995/96 to 2012/13). In the past eighteen years, the livestock population namely cattle, sheep and goat grew from 54.5 million to over 103.5 million with average annual increment of 3.4 million. The current average national cattle, sheep and goat population per km(2) are estimated to be 71, 33 and 29 respectively (excluding Addis Ababa, Afar and Somali regions). From the total livestock population the country owns about 46% cattle, 43% sheep and 40% goats are reared within 10 km radius from major livestock market centres and all-weather roads. On the other hand, three fourth of the country's land mass which comprises 15% of the cattle, 20% of the sheep and 21% of goat population is not accessible to market (greater than 30 km from major livestock market centres). It is found that the central highland regions account for the largest share of livestock population and also more accessible to market. Defining the

    Several domains of contrasted extensional deformation have been identified in the southern Afar triangle (East Africa) from fault patterns analyzed with panchromatic stereoscopic SPOT (Système Probatoire d'Observation de la Terre) images. Stretching directions and statistical orientation and offset variations of faults fit with the Danakii "crank-arm" model of Sichler: A 10° sinistral rotation of the Danakil block explains the fault geometry and dextral block rotation in the southern part of the Afar triangle, as well as the oblique extension in the Tadjoura Gulf. Analogue modeling supports this interpretation.

    Full Text Available Background: Death related to unintended pregnancy associated events is a series public health concern in Ethiopia. This is very common in young adolescents for whom life is full of adventure and temptation with very little knowledge about the consequences of their reckless activities. Emergency contraceptives are the only method that can be used within short time after sexual intercourse, offering a second chance to prevent unwanted pregnancy. Objectives: To assess the knowledge, attitude and practice of emergency contraceptives among female college students at Mekelle town, Ethiopia.Methods: An institutional based cross-sectional survey was conducted among 616 female college students at Mekelle town from March to July, 2011. Multistage sampling technique with Probabilities proportional to size was used. Data were analyzed by SPSS window version 16.0 software package and presented using frequencies, percentages. Crude & adjusted odds ratio were used to control the possible confounding variables. Results: Of the total respondents, 393(67.3% of them replied that they have heard about emergency contraceptives. Among those who have ever heard of emergency contraceptives, 224 (57% mentioned pills only, 9 (2.3% mentioned intrauterine contraceptive devices only and 154(39.2% mentioned both pill & IUCDs. 263(45% of the respondents were knowledgeable towards ECs, and about 271(46.4% of the students had positive attitude towards emergency contraceptives. Of the sexually active respondents 70(24.2% only reported that they had used emergency contraceptive methods previously. Whereas, 219(75.8% were not used emergency contraceptives; some of the reasons were lack of knowledge about ECs (42.9%; no desire to use (22.8% and inaccessibility toward emergency contraceptives (16.4%.Conclusion: The study indicated low level of knowledge; very low level of practice and majority showed negative attitude towards emergency contraceptives.

    This review focuses on the reports of salmonellosis by investigators in different parts of Ethiopia, in particular focusing on the levels of typhoid fever. Many of the reports are published in local journals that are not available online. There have been seven studies which diagnosed typhoid fever by laboratory culture and there is no coordinated epidemiological surveillance. All conducted research and reports from different health institutions in Ethiopia indicate that typhoid fever was still a common problem up to the most recent study in 2000 and that the extensive use of first-line drugs has led to the development of multiple drug resistance. In the sites covered by this review, the total number of published cases of typhoid fever dropped over time reflecting the decline in research capacity in the country. Data on the proportion of patients infected by different serovars of Salmonella suggest that the non-Typhi serovars of Salmonella are increasing. The published evidence suggests that typhoid fever is a current public health problem in Ethiopia although population based surveys, based on good microbiological diagnosis, are urgently needed. Only then can the true burden of enteric fever be estimated and the benefit of public health control measures, such as health education, safe water provision, improved food hygienic practices and eventually vaccination, be properly assessed.

    Full Text Available Bovine tuberculosis (bTB infection is generally correlated with individual cattle's age, sex, body condition, and with husbandry practices such as herd composition, cattle movement, herd size, production system and proximity to wildlife-including bTB maintenance hosts. We tested the correlation between those factors and the prevalence of bTB, which is endemic in Ethiopia's highland cattle, in the Afar Region and Awash National Park between November 2013 and April 2015. A total of 2550 cattle from 102 herds were tested for bTB presence using the comparative intradermal tuberculin test (CITT. Data on herd structure, herd movement, management and production system, livestock transfer, and contact with wildlife were collected using semi-structured interviews with cattle herders and herd owners. The individual overall prevalence of cattle bTB was 5.5%, with a herd prevalence of 46%. Generalized Linear Mixed Models with a random herd-effect were used to analyse risk factors of cattle reactors within each herd. The older the age of the cattle and the lower the body condition the higher the chance of a positive bTB test result, but sex, lactation status and reproductive status were not correlated with bTB status. At herd level, General Linear Models showed that pastoral production systems with transhumant herds had a higher bTB prevalence than sedentary herds. A model averaging analysis identified herd size, contact with wildlife, and the interaction of herd size and contact with wildlife as significant risk factors for bTB prevalence in cattle. A subsequent Structural Equation Model showed that the probability of contact with wildlife was influenced by herd size, through herd movement. Larger herds moved more and grazed in larger areas, hence the probability of grazing in an area with wildlife and contact with either infected cattle or infected wildlife hosts increased, enhancing the chances for bTB infection. Therefore, future bTB control strategies

    Oaks represent one of the most important plant genera in the Northern hemisphere and include many intensively VOC emitting species. The major group constitutes the isoprene emitters, but also monoterpene emitters and non-emitters can be found. These variations in the oak species might partly be due to their propensity for inter- and intraspecific hybridisation. This study addresses the foliar VOC production of the former hybridisation product the deciduous Quercus afares and its parents, two very distant species: the evergreen monoterpene emitter Quercus suber and the deciduous isoprene emitter Quercus canariensis. The measurements were performed in Southern France, applying two different methods. Plants were investigated in situ in the field with a portable gas exchange measuring system as well as in the laboratory on cut branches with an adapted enclosure system. Quercus afares was found to be a monoterpene emitting species. However, the monoterpene emission was lower and the composition different to that of Quercus suber. Whereas Quercus suber trees belonged to the pinene type most individuals of Quercus afares were identified to represent a limonene type. Quercus canariensis emitted besides high amounts of isoprene also linalool and (Z)-3-hexenylacetate. Emissions from Quercus suber and Quercus afares were higher in the field measurements than in the laboratory on cut branches whereas Quercus canariensis exhibited lower isoprene emissions from cut branches. The results demonstrate the need of further emission studies on a plant species level.

    We undertook ethnobotanical study of forage/fodder plant species used by the Afar and Oromo (Kereyu and Ittu) Nations in and around the semi-arid Awash National Park (ANP), Ethiopia. The study aimed at investigating and documenting indigenous knowledge (IK) on forage/fodder plant species and threats to their survival. Ninety-six in-formants between 20 and 80 years old were selected using prior informa-tion. Data were collected using semi-structured interview, guided field walk, discussion and field observation. Preference ranking, Jaccard’s coefficient of similarity and priority ranking were used for data analysis. One hundred twenty-six forage/fodder species of 90 genera and 43 fami-lies were collected in the study area. More than 88%of the species were reported with their vernacular names, where 68% were reported by the Afar Nation and 70%by the Oromo Nation. Family Poaceae was repre-sented by 25 species (20%), followed by Fabaceae 18 (14%). Preference ranking for the most preferred forage grasses as perceived by key infor-mants revealed that Chrysopogon plumulosus was the most important forage/fodder species. Overgrazing was the major threat in the study area, scoring 22%.

    Introduction The present study describes the distribution of selected micronutrients and anaemia among school-aged children living in Libo Kemkem and Fogera (Amhara State, Ethiopia), assessing differences by socio-demographic characteristics, health status and dietary habits. Methods A cross-sectional survey was carried out during May–December 2009. Socio-demographic characteristics, health status and dietary habits were collected. Biomarkers were determined for 764 children. Bivariate and multivariable statistical methods were employed to assess micronutrient deficiencies (MD), anaemia, and their association with different factors. Results More than two thirds of the school-aged children (79.5%) had at least one MD and 40.5% had two or more coexisting micronutrient deficiencies. The most prevalent deficiencies were of zinc (12.5%), folate (13.9%), vit A (29.3%) and vit D (49%). Anaemia occurred in 30.9% of the children. Children living in rural areas were more likely to have vit D insufficiency [OR: 5.9 (3.7–9.5)] but less likely to have folate deficiency [OR: 0.2 (0.1–0.4)] and anaemia [OR: 0.58 (0.35–0.97)]. Splenomegaly was positively associated with folate deficiency and anaemia [OR: 2.77 (1.19–6.48) and 4.91 (2.47–9.75)]. Meat and fish consumption were inversely correlated with zinc and ferritin deficiencies [OR: 0.2 (0.1–0.8) and 0.2 (0.1–0.9)], while oil consumption showed a negative association with anaemia and deficiencies of folate and vitamin A [0.58 (0.3–0.9), OR: 0.5 (0.3–0.9) and 0.6 (0.4–0.9)]. Serum ferritin levels were inversely correlated to the presence of anaemia (p<0.005). Conclusion There is a high prevalence of vitamin A deficiency and vitamin D insufficiency and a moderate prevalence of zinc and folate deficiencies in school-aged children in this area. The inverse association of anaemia and serum ferritin levels may be due to the presence of infectious diseases in the area. To effectively tackle malnutrition

    Pastoralism is the most dominant land use form in the arid rangelands of Sub-Saharan Africa, but this rangeland-based lifestyle is under threat. As a consequence a study was conducted in the Middle Awash Valley of Ethiopia with the main objectives of assessing and comparing the broad perceptions of two pastoral groups (the Oromo ethnic group living in Kereyu-Fantale and the Afar ethnic group living in Awash-Fantale) on the usage of the existing rangeland resources, and their views on constraints and possible solutions. Data were collected from 90 Oromo and 55 Afar households. Despite the difference in ethnicity both of these groups share common problems. They derive their main income from the sale of animals and animal products, but with the difference that milk products rank first in the case of the Afar and last in the case of the Oromo. Both pastoral groups depend heavily on native grasses for animal feed and to a lesser extent on woody plants as a source of browse. The majority of respondents were of the opinion that the condition of the rangelands is poor, mainly due to overgrazing, droughts and increases in the human population. Availability of water is also regarded as a problem, mainly by the Oromo. Migration is the first measure taken to solve shortages of livestock feed, but many of the pastoralists replied that migration is an undesirable practise which is mostly done out of necessity. Because of the limited resources most respondents of both groups still prefer communal land tenure where resources are shared. It is concluded that the problems facing the pastoralists in the Middle Awash Valley have been created over many years and the solutions will also require time. With the current approach of the communal grazing systems, sustainable utilisation of the rangeland ecosystem is not possible. Solutions to the poor condition of the existing rangelands will require a definite commitment and full participation not only of the pastoralists, but also of

    Full Text Available Abstract Background Neglected tropical diseases (NTDs are a group of chronic parasitic diseases and related conditions that are the most common diseases among the 2·7 billion people globally living on less than US$2 per day. In response to the growing challenge of NTDs, Ethiopia is preparing to launch a NTD Master Plan. The purpose of this review is to underscore the burden of NTDs in Ethiopia, highlight the state of current interventions, and suggest ways forward. Results This review indicates that NTDs are significant public health problems in Ethiopia. From the analysis reported here, Ethiopia stands out for having the largest number of NTD cases following Nigeria and the Democratic Republic of Congo. Ethiopia is estimated to have the highest burden of trachoma, podoconiosis and cutaneous leishmaniasis in sub-Saharan Africa (SSA, the second highest burden in terms of ascariasis, leprosy and visceral leishmaniasis, and the third highest burden of hookworm. Infections such as schistosomiasis, trichuriasis, lymphatic filariasis and rabies are also common. A third of Ethiopians are infected with ascariasis, one quarter is infected with trichuriasis and one in eight Ethiopians lives with hookworm or is infected with trachoma. However, despite these high burdens of infection, the control of most NTDs in Ethiopia is in its infancy. In terms of NTD control achievements, Ethiopia reached the leprosy elimination target of 1 case/10,000 population in 1999. No cases of human African trypanosomiasis have been reported since 1984. Guinea worm eradication is in its final phase. The Onchocerciasis Control Program has been making steady progress since 2001. A national blindness survey was conducted in 2006 and the trachoma program has kicked off in some regions. Lymphatic Filariasis, podoconiosis and rabies mapping are underway. Conclusion Ethiopia bears a significant burden of NTDs compared to other SSA countries. To achieve success in integrated control of

    Ethiopia has begun seriously developing their significant hydropower potential by launching construction of the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile River to facilitate local and regional growth. Although this has required substantial planning on Ethiopia's part, no policy dictating the reservoir filling rate strategy has been publicly issued. This filling stage will have clear implications on downstream flows in Sudan and Egypt, complicated by evaporative losses, climate variability, and climate change. In this study, various filling policies and future climate states are simultaneously explored to infer potential streamflow reductions at Lake Nasser, providing regional decision-makers with a set of plausible, justifiable, and comparable outcomes. Schematic of the model framework Box plots of 2017-2032 percent change in annual average streamflow at Lake Nasser for each filling policy constructed from the 100 time-series and weighted precipitation changes. All values are relative to the no dam policy and no changes to future precipitation.

  14. New age constraints on the timing of volcanism in central Afar, in the presence of propagating rifts

    We investigate the relationship between rift propagation and volcanism in the Afar Depression in the last 4 Myr. Potassium-argon and thermoluminescence dating allow detailed reconstruction of the temporal evolution of volcanism. Volcanic activity is almost continuous since 3.5 Ma, with intervals characterized by more intense activity, especially around 2 Ma. Spatial distribution of ages reveals that Stratoid Series volcanism migrated northward along a 200-km trend between 3 and 1 Ma, at about 10 cm/yr, linked to northward propagation of the Gulf of Aden Ridge, after it had cut across the Danakil horst at 4 Ma. Our work underlines the role of rhyolitic volcanism in initiation of rifting. Acid volcanoes, initially formed near the axes of extensional zones, have been subsequently dissected and are presently located on both sides of active rift segments. These lavas were the first to be erupted in areas of low extensional strain and were followed by basaltic lavas as extension increased. Differentiated volcanoes acted as zones of local weakness and guided localization of fractures, then leading to fissural magmatism. This regional-scale, composite style of rifting, including volcanic and tectonic components, can be compared to the large-scale continental breakup process itself. Deformation occurs through propagation of faults and fissures under a regional stress field. These become localized because of weakening of the crust (or lithosphere) due to emplacement of magmas, under the influence of a plume in the large-scale case, or of silicic centers linked to magma chambers in the regional-scale case.

    Urban formations at the national,regional and urban district levels in China are discussed.Observations at the national level concern spatio-temporal distributions of regional and county-level cities,as well as designated towns,since 1950,and references to comparable western patterns of urbanization are made.At a regional level and especially for the Yangtze River Delta Region,less well-controlled development appears primarily in conurbated areas between relatively well-managed cities and towns,often causing adverse environmental consequences and economic inefficiencies.At local urban district levels,characteristics of large-block developments are compared with western counterparts,as well as with earlier conditions of Chinese urbanization.Although future adaptation appears possible,problems include a relative inflexibility in prevailing building types,inefficiencies of coarse-grained infrastructure distribution,and potential isolation from relatively high degrees of selfcontainment.

  17. Geologic and geochronologic constraints on the evolution of the Red Sea-Gulf of Aden and Afar depression

    Science.gov (United States)

    Berhe, Seife M.

    New KAr age determinations show that the development of Southern Afar since 14 Ma ago involved five stages of tectonism and volcanism at 14-11, 11-10, 9-7, 5-4 and post-1.6 Ma ago; while the major phases of rifting for the Red Sea-Gulf of Aden have been shown by geological and geophysical data to be 25, 14, 10 and 4 Ma ago. It is suggested that since 14 Ma ago, identical periods of volcanism preceded by rifting have affected both areas. Continental breakup in the Red Sea region was initiated along large transcurrent faults followed by extension manifested by normal faulting, block tilting in the brittle crustal region and repeated dyke injection. Two large scale transcurrent faults were identified, the Marda (NW-SE) and the Ambo (ENE-WSW) which, it is suggested, controlled the trends of rifting in the Red Sea and Gulf of Aden, respectively. Structural and geological evidence indicate that these faults have had a relatively long history, since they were active in pre-Jurassic times. Because at least the Ambo fault cuts across the NS trends of the late Proterozoic basement, its orientation must be primarily related to the Phanerozoic rift tectonics. This model avoids overlap of the Arabian plate with the Danakil and Aisha blocks because it involves only limited true oceanic crust. The new age data indicate that the initiation of the Aden and Red Sea rifts was not accompanied by active volcanism on land until the Oligocene-Miocene (30-5 Ma ago). Following that time, volcano-tectonic rifting continued without substantial hiati.

    Full Text Available The study was carried out at Metekel ranch, Amhara region, Ethiopia, with the objective of estimating genetic parameters for reproductive traits of Fogera and Holstein Friesian crossbreed cattle. The data used in the study included pedigree records and reproductive performance records of animals born from 1990 to 2012.The parameters were estimated by using Variance Component Estimation (VCE 6.0 software. Four models were used Viz. Model1: Y= Xb+Z1a + e; Model2:Y=Xb+Z1a+Z3c + e; Model3: Y=Xb+Z1a+Z2m+ e; cov a,m=0 and Model4: Y= Xb + Z1a + Z2m+ Z3c + e; cov a, m=0.Traits like Gestation Length (GL, Calving Interval (CI and Days Open(DO were estimated using model2 and 4 which fit permanent environmental effect due to repeated records per cow. Whereas, age at first service (AFS and age at first calving (AFC were estimated using model 1, 3, and 4. Estimates of direct heritability of the studied traits ranged from 0.01±0.05 for DO to 0.26±0.21 for AFS, besides high error variance was observed. The phenotypic correlations between traits ranged: 0.33 to 0.99 between CI and DO and GL and DO respectively. And genetic correlations ranged from -1.0 to 1.0 between GL and CI between CI and DO respectively. The result in this study indicates there were low heritability estimates high environmental variances which imply selection based on phenotypic performance of animals was unlikely to bring genetic progress in the studied herd because of the low estimate of heritability of the trait. Besides, The result showed there was moderate to high correlation that indicated selection for one trait will affect the correlated traits. Thus, selection method, in addition to individual records, should incorporate pedigree and progeny information in the form of an index to get optimum genetic progress in the studied population. In addition, selection for any particular trait(s must be carried out with caution as it could have an adverse effect due to correlated response on

    Full Text Available Introduction. HIV/AIDS-related stigma occurs in the world towards people living with HIV/AIDS in a different form. Stigma among nurses in health care setting is one of the main challenges towards the prevention and management of HIV/AIDS in developing countries. It is one of the main reasons keeping patients from seeking health care service. Therefore assessing the magnitude of stigma and associated factors towards people living on HIV/AIDS among nurses is of paramount importance for the quality of nursing care as well as service utilization. Methods. An institutional based cross-sectional study was conducted in March 2013. Pretested and structured questionnaire via self-administration was used in the tool of HIV/AIDS Stigma Instrument-Nurse (HASI-N. Data were entered using EPI info version 3.5.3 and transferred to SPSS version 20 for further analysis. Descriptive statistics were conducted to summarize the sample characteristics. A backward stepwise logistic regression model was fitted and adjusted odds ratio with 95% confidence interval was calculated to identify associated factors. Results. A total of 386 nurses participated yielding a response rate of 97.2%. Nearly two-thirds (64.5% of them have shown stigma towards people living with HIV/AIDS in the health institution. Qualification level of diploma or certificate, lack of training, experiences of <06 years, low HIV patient caseload seen in the last six months, and the absence of guidelines/protocols about HIV/AIDS in their health institution were associated factors for stigma. Conclusions. The findings of this research showed high magnitude of stigma towards people living with HIV/AIDS among nurses. For stigma to be decreased nurses need to update their knowledge through training and experience sharing with senior staff. And it is crucial that the Ethiopian Ministry of Health, Amhara Regional Health Bureau, and the two hospitals work for decreasing stigma by creating educational development

    Full Text Available BACKGROUND: In sub-Sahara Africa, more than 60% of all new HIV infections are occurring in women, infants and young children. Maternal to child transmission is responsible for 90% of childhood HIV infection. Preventing unwanted pregnancy among HIV positive women is imperative to reduce maternal and infant morbidity and mortality. METHODS: A cross-sectional survey was conducted among 964 HIV positive women in selected 12 health centers of Tigray region. In this paper, analysis was restricted only for 847 women who were sexually active and non-pregnant. In each health center the number of study participants was allocated proportionally to the load of HIV positive women in chronic care clinics. The data were entered into EpiData version 3.1, and cleaned and analyzed using Stata version 11.1. Descriptive summary of data and logistic regression were used to identify possible predictors using odds ratio with 95% confidence interval and P-value of 0.05. FINDINGS: Three hundred ninety four (46.5% of all HIV positive women had intension to have more children. Three hundred seventy five (44.3% were using contraceptive methods at time of survey. Injectable (70.7% and male condom (47.6% were most commonly used type of contraceptives. In the multivariable analysis, women who were urban dwellers (AOR = 2.55; 95% CI: 1.27, 5.02, completed primary education (AOR = 2.27; 95% CI: 1.12, 2.86 and those openly discussed about contraceptive methods with their husbands or sexual partners (AOR = 6.3; 95% CI: 3.42, 11.76 were more likely to use contraceptive. Women who have one or more living children were also more likely to use contraceptive compared with women with no child. CONCLUSION: Less than half of women used contraceptive methods. The use of condoms could impact unintended pregnancies and reduced risks of vertical and sexual transmission. Efforts to increase contraceptive utilization focusing on the barrier methods should be strengthen in HIV

    In Ethiopia, the Italian Association for Women in Development (AIDOS) has been working with Ethiopia's National Committee on Traditional Practices Affecting the Health of Women and Children for 5 years. AIDOS began working on female genital mutilation in the early 1980s and rejects charges of cultural imperialism that are applied to Northern organizations attempting to help African organizations address this violation of universal human rights. In Ethiopia, 85% of women are mutilated, with most undergoing Sunna, or removal of the prepuce of the clitoris. The joint project seeks to increase awareness about the health consequences of female genital mutilation in the target group. The primary technique used is provision of training of trainers courses and presentation of four modular units and audiovisual materials specifically designed for use with socially influential women, male and female secondary school students, community leaders, and health workers. In addition, an information/education campaign uses videos and sound and slide shows with accompanying story books. A second category of communication tools was developed for a mass information campaign, including radio spots, posters, information leaflets, and a newsletter. When the project was ready for expansion into the southern region of the country, it became clear that a new participatory communication strategy was required to stimulate discussion, such as the use of role playing and theater. Working together, the two organizations have successfully confronted project constraints such as the difficulty in assessing project impact, scheduling problems, and gender-biased assess to information.

  9. Seasonal Water Balance Forecasts for Drought Early Warning in Ethiopia

    Droughts severely impact Ethiopian agricultural production. Successful early warning for drought conditions in the upcoming harvest season therefore contributes to better managing food shortages arising from adverse climatic conditions. So far, however, meteorological seasonal forecasts have not been used in Ethiopia's national food security early warning system (i.e. the LEAP platform). Here we analyse the forecast quality of seasonal forecasts of total rainfall and of the meteorological water balance as a proxy for plant available water. We analyse forecast skill of June to September rainfall and water balance from dynamical seasonal forecast systems, the ECMWF System4 and EC-EARTH global forecasting systems. Rainfall forecasts outperform forecasts assuming a stationary climate mainly in north-eastern Ethiopia - an area that is particularly vulnerable to droughts. Forecasts of the water balance index seem to be even more skilful and thus more useful than pure rainfall forecasts. The results vary though for different lead times and skill measures employed. We further explore the potential added value of dynamically downscaling the forecasts through several dynamical regional climate models made available through the EU FP7 project EUPORIAS. Preliminary results suggest that dynamically downscaled seasonal forecasts are not significantly better compared with seasonal forecasts from the global models. We conclude that seasonal forecasts of a simple climate index such as the water balance have the potential to benefit drought early warning in Ethiopia, both due to its positive predictive skill and higher usefulness than seasonal mean quantities.

    Full Text Available Abstract Background More than 75% of the total area of Ethiopia is malarious, making malaria the leading public health problem in Ethiopia. The aim of this study was to investigate the prevalence rate and the associated socio-economic, geographic and demographic factors of malaria based on the rapid diagnosis test (RDT survey results. Methods From December 2006 to January 2007, a baseline malaria indicator survey in Amhara, Oromiya and Southern Nation Nationalities and People (SNNP regions of Ethiopia was conducted by The Carter Center. This study uses this data. The method of generalized linear model was used to analyse the data and the response variable was the presence or absence of malaria using the rapid diagnosis test (RDT. Results The analyses show that the RDT result was significantly associated with age and gender. Other significant covariates confounding variables are source of water, trip to obtain water, toilet facility, total number of rooms, material used for walls, and material used for roofing. The prevalence of malaria for households with clean water found to be less. Malaria rapid diagnosis found to be higher for thatch and stick/mud roof and earth/local dung plaster floor. Moreover, spraying anti-malaria to the house was found to be one means of reducing the risk of malaria. Furthermore, the housing condition, source of water and its distance, gender, and ages in the households were identified in order to have two-way interaction effects. Conclusion Individuals with poor socio-economic conditions are positively associated with malaria infection. Improving the housing condition of the household is one of the means of reducing the risk of malaria. Children and female household members are the most vulnerable to the risk of malaria. Such information is essential to design improved strategic intervention for the reduction of malaria epidemic in Ethiopia.

    A {sup 40}Ar/{sup 39}Ar thermo-chronological study has been carried out for two contrasted geodynamic settings: - the Eastern Kunlun range (Northern Tibet), in order to characterize the lithospheric deformation mechanisms related to the India-Asia collision; - the Afar triple junction area (East Africa), in order to constrain the timing of mantle plume-related basement uplift in Ethiopia and Yemen, which will indicate whether rifting was active or passive. In the Kunlun, the cooling event (9-15 deg.C/Ma) outlined at 30 Ma for the granitoids (Bt = 128-138 Ma; Kf = 102-147 Ma) reflects a denudation event (0.2-0.3 km/Ma), related to ramp stacking and normal faulting with associated uplift. This unroofing period is coeval with the great Asian strike-slip faults. This suggests that 30 Ma ago, the India-Asia collision was accommodated by lateral extrusion along great strike-slip faults, which might have led to local crustal thickening because of the formation of anticlines from major thrusts 'branching' from the Kunlun fault. In the Afar area the Panafrican basement (granitoids = 462-678 Ma;metamorphic rocks 505-750 Ma) has undergone a reheating event during the Cenozoic; its temperature is estimated around 138-177 deg.C over the last 50 Ma for a depth of 2 km, implying a thermal gradient of 69-88 deg./km. This reheating event results from both heat conduction, related to the mantle plume. and heat advection. because of magma transfer. However, it was not possible to define the timing of the mantle plume-related basement uplift. This study outlines the important thermal effect of continental flood basalts on the crust and suggests that the {sup 40}Ar/{sup 39}Ar thermo-chronology does not allow to characterize the denudation of the lithosphere for an extension-type geodynamic setting. Finally, some of the results suggest that diffusion in the laboratory and in nature may be different. {sup 40}Ar/{sup 39}Ar thermo-chronological analysis thus might be tricky

    Cochrane, Logan; O'Regan, Davin

    2016-04-01

    The production of khat in Ethiopia has boomed over the last two decades, making the country the world's leading source. Khat is now one of Ethiopia's largest crops by area of cultivation, the country's second largest export earner, and an essential source of income for millions of Ethiopian farmers. Consumption has also spread from the traditional khat heartlands in the eastern and southern regions of Ethiopia to most major cities. This steady growth in production and use has unfolded under negligible government support or regulation. Meanwhile, khat, which releases a stimulant when chewed, is considered an illicit drug in an increasing number of countries. Drawing on government data on khat production, trade, and seizures as well as research on the political, socioeconomic, and development effects of plant-based illicit narcotics industries, this commentary identifies possible considerations and scenarios for Ethiopia as the country begins to manage rising khat production, domestic consumption, and criminalization abroad. Deeply embedded in social and cultural practices and a major source of government and agricultural revenue, Ethiopian policymakers have few enviable choices. Criminalization abroad raises a small but not insignificant possibility that previously nonexistent linkages between khat and transnational organized crime and trafficking networks will emerge. Likewise, more stringent regulation of khat in Ethiopia could merge with lingering political cleavages and anti-government sentiments, exacerbating low-level domestic conflicts.

The discovery in the Northern Danakil (Afar) Depression, Eritrea, of a well-preserved Homo cranium with a mixture of characters typical of H. erectus and H. sapiens contributes significantly to this debate. The cranium was found in a succession of fluvio-deltaic and lacustrine deposits and is associated with a rich mammalian fauna of early to early-middle Pleistocene age. A magnetostratigraphic survey indicates two reversed and two normal magnetozones. The layer in which the cranium was found is near the top of the lower normal magnetozone, which is identified as the Jaramillo subchron. Consequently, the human remains can be dated at approximately 1 million years before present.

    With the growth in engineering/technology industries, the United States has seen an increase in the arrival of highly skilled temporary migrant workers on H1B visas from various Asian countries. Limited research exists on how these groups maintain family ties from afar including caring for aging parents. This study explores the experiences and challenges that Asian H1B workers face when providing care from a distance. A total of 21 Chinese/Taiwanese, Korean, and Indian H1B workers participated in in-depth qualitative interviews. Key findings indicate that despite distance, caring relationships still continue through regular communications, financial remittances, and return visits, at the same time creating emotional, psychological, and financial challenges for the workers. Findings highlight the need for further research in understanding how the decline of aging parent's health impacts the migrants' adjustment and health in the United States.

    Full Text Available In last decade, Ethiopia witnesses so far unseen economic growth while the transformation to democracy more or less failed. Due to the fact that the Horn of Africa belongs to the most unstable regions in Africa, external factors play a significant role in shaping and reshaping of internal politics of each state. In this study, we will focus on an analysis of external factors and their impact on security and politics in Ethiopia. As we argue, it is these factors that have a substantial impact on Ethiopian politics and security.

    The Danakil depression in the northern part of the Afar rift is a location of incipient oceanic spreading. Deformation associated with recent magmatic events provides a view of the incremental stages in rifting. Using Interferometric Synthetic Aperture Radar (InSAR) and geodetic modeling, this study assesses magmatic events that occurred in October 2004 and November 2008 in the axial graben of the Danakil depression. The study utilized C-band Envisat ASAR imagery and L-band ALOS PALSAR imagery. Both events involve deflation of magma chambers and intrusion of NNW-SSE striking dikes. The 2004 event took place in the Dallol area and involved ~5 km deep magmatic source and a SSE-propagating dike that opens approximately 80 - 120 cm - this contrasts with seismological results suggesting a 20 km depth with primarily normal faulting. The 2008 event occurred on the northern segment of the Erta Ale volcanic range between Alu and Dalafillal volcanic centers. Available image data permitted assessing pre- and post-event deformation, as well as the main eruption. Interferograms spanning the 2008 eruption image the deflation of a 3 - 4 km deep magmatic source, as well as dilatation of a SSE-striking dike. Additionally, the erupted lava flow is evident as a decorrelated region along the northeast flank of the fissure event. Prior to the eruption, the inflation of the magmatic chamber is imaged, and after the eruption, resurgence of the magma chamber is also documented. Furthermore, post-eruption interferograms also document the contraction and cooling of the lava flow, which facilitates 1-dimensional modeling of the thickness of the flow and calculation of the volume of the effusive component of the eruption. In both cases, aseismic deformation dominates - i.e., the seismologically measured moment is significantly less than the geodetically observed moment: ~25% for the 2004 event and 10% for the 2008 event. Magnitudes of incremental extension are then compared with regional

    Truthful and reliable seasonal rainfall predictions have an important social and economic value for the east African countries as their economy is highly dependent on rain-fed agriculture and pastoral systems. Only June to September (JJAS) seasonal rainfall accounts to more than 80% crop production in Ethiopia. Hence, seasonal foresting is a crucial concern for the region. The European Provision of Regional Impact Assessment on a seasonal to decadal timescale (EUPORIAS) project offers a common framework to understand hindcast uncertainties through the use of multi-model and multi-member simulations over east Africa. Under this program, the participating regional climate models (RCMs) were driven by the atmospheric-only version of the ECEARTH global climate model, which provides hindcasts of a five-months period (May to September) from 1991-2012. In this study the RCMs downscaled rainfall is evaluated with respect to the observed JJAS rainfall over Ethiopia. Both deterministic and probabilistic based forecast skills are assessed. Our preliminary results show the potential usefulness of multi-model ensemble simulations in forecasting the seasonal rainfall over the region.

  5. Mapping and Modelling the Geographical Distribution and Environmental Limits of Podoconiosis in Ethiopia.

    Full Text Available Ethiopia is assumed to have the highest burden of podoconiosis globally, but the geographical distribution and environmental limits and correlates are yet to be fully investigated. In this paper we use data from a nationwide survey to address these issues.Our analyses are based on data arising from the integrated mapping of podoconiosis and lymphatic filariasis (LF conducted in 2013, supplemented by data from an earlier mapping of LF in western Ethiopia in 2008-2010. The integrated mapping used woreda (district health offices' reports of podoconiosis and LF to guide selection of survey sites. A suite of environmental and climatic data and boosted regression tree (BRT modelling was used to investigate environmental limits and predict the probability of podoconiosis occurrence.Data were available for 141,238 individuals from 1,442 communities in 775 districts from all nine regional states and two city administrations of Ethiopia. In 41.9% of surveyed districts no cases of podoconiosis were identified, with all districts in Affar, Dire Dawa, Somali and Gambella regional states lacking the disease. The disease was most common, with lymphoedema positivity rate exceeding 5%, in the central highlands of Ethiopia, in Amhara, Oromia and Southern Nations, Nationalities and Peoples regional states. BRT modelling indicated that the probability of podoconiosis occurrence increased with increasing altitude, precipitation and silt fraction of soil and decreased with population density and clay content. Based on the BRT model, we estimate that in 2010, 34.9 (95% confidence interval [CI]: 20.2-51.7 million people (i.e. 43.8%; 95% CI: 25.3-64.8% of Ethiopia's national population lived in areas environmentally suitable for the occurrence of podoconiosis.Podoconiosis is more widespread in Ethiopia than previously estimated, but occurs in distinct geographical regions that are tied to identifiable environmental factors. The resultant maps can be used to guide

    Australopithecus afarensis is the best-known and most dimorphic species in the early hominin fossil record. Here, we present a comparative description of new fossil specimens of Au. afarensis from Nefuraytu, a 3.330-3.207 million-years-old fossil collection area in the Woranso-Mille study area, central Afar, Ethiopia. These specimens include NFR-VP-1/29, one of the most complete mandibles assigned to the species thus far and among the largest mandibles attributed to Au. afarensis, likely representing a male individual. NFR-VP-1/29 retains almost all of the distinctive archaic features documented for Au. afarensis. These features include a posteriorly sloping symphysis, a low and rounded basally set inferior transverse torus, anterosuperiorly opening mental foramen, a lateral corpus hollow bound anteriorly by the C/P3 jugae and posteriorly by the lateral prominence, and the ascending ramus arising high on the corpus. Dental morphology and metrics of the Nefuraytu specimens also falls within the range of Au. afarensis. The presence of this species at Woranso-Mille between 3.330 and 3.207 million years ago confirms the existence of this species in the area in close spatial and temporal proximity to other middle Pliocene hominin taxa such as the one represented by the Burtele foot (BRT-VP-2/73) and the recently named species Australopithecus deyiremeda. This has important implications for our understanding of middle Pliocene hominin diversity.

    Hybridisation is a potent force in plant evolution, although there are few reported examples of stabilised species that have been created through homoploid hybridisation. We focus here on Quercus afares, an endemic North African species that combines morphological, physiological and ecological traits of both Q. suber and Q. canariensis, two phylogenetically distant species. These two species are sympatric with Q. afares over most of its distribution. We studied two Q. afares populations (one from Algeria and one from Tunisia), as well as several populations of both Q. suber and Q. canariensis sampled both within and outside areas where these species overlap with Q. afares. A genetic analysis was conducted using both nuclear (allozymes) and chloroplastic markers, which shows that Q. afares originates from a Q. suber x Q. canariensis hybridisation. At most loci, Q. afares predominantly possesses alleles from Q. suber, suggesting that the initial cross between Q. suber and Q. canariensis was followed by backcrossing with Q. suber. Other hypotheses that can account for this result, including genetic drift, gene silencing, gene conversion and selection, are discussed. A single Q. suber chlorotype was detected, and all Q. afares individuals displayed this chlorotype, indicating that Q. suber was the maternal parent. Q. afares is genetically, morphologically and ecologically differentiated from its parental species, and can therefore be considered as a stabilised hybrid species.

    This brief report, drawing from a multi-year effort by the U.S. Agency for International Development (USAID) Famine Early Warning Systems Network (FEWS NET), examines recent trends in March-June, June-September, and March-September rainfall and temperature, identifying significant reductions in rainfall and increases in temperature over time in many areas of Ethiopia. Conclusions: * Spring and summer rains in parts of Ethiopia have declined by 15-20 percent since the mid-1970s. * Substantial warming across the entire country has exacerbated the dryness.* An important pattern of observed existing rainfall declines coincides with heavily populated areas of the Rift Valley in south-central Ethiopia, and is likely already adversely affecting crop yields and pasture conditions. * Rapid population growth and the expansion of farming and pastoralism under a drier, warmer climate regime could dramatically increase the number of at-risk people in Ethiopia during the next 20 years.* Many areas of Ethiopia will maintain moist climate conditions, and agricultural development in these areas could help offset rainfall declines and reduced production in other areas.

  10. The development of extension and magmatism during continent-ocean transition: evidence from Ethiopia

    The geological record at rifts and margins worldwide often reveals along-strike variations in volumes of extruded and intruded igneous rocks. These variations may be the result of asthenospheric heterogeneity, variations in rate and timing of extension. Preexisting plate architecture and/or the evolving kinematics of extension during breakup may also influence magmatism strongly. The Ethiopian and Afar Rift systems provide an excellent opportunity to address these issues since they expose, along strike, several sectors of ongoing, asynchronous rift development from embryonic continental rifting in the south to incipient oceanic spreading in the north. A consensus has now emerged from a variety of disciplines in Ethiopia that a considerable proportion of extension in Ethiopia is accommodated by focused dyke intrusion in narrow axial zones, without marked crustal (and plate?) thinning. These "magmatic segments" may mark the final breakup boundary and location of an incipient oceanic spreading centre. However, observations of markedly thinned crust and a pulse in Quaternary-Recent basaltic volcanism within the Danakil Depression have recently been cited as evidence that an abrupt, late stage of localised plate stretching may instead mark the final stages of continent-ocean transition (Bastow & Keir, 2011). We explore this hypothesis using recently-acquired seismic reflection data and accompanying borehole geological constraints from Danakil. Thick sequences of evaporites have been deposited in an asymmetric basin, whose subsidence has been controlled primarily by a major, east dipping normal fault. Surprisingly, no significant magmatism is observed in the upper ~1000m. Age constraints on a potash-bearing sequence presently being mined in the basin point towards rapid basin infill in the last several tens-to-hundreds of thousands of years. Basin formation cannot be easily attributed to the effects of magmata intrusion. Instead, an abrupt, localised, late-stage, plate

    Full Text Available The allelopathic effects of the invasive Prosopis juliflora (Sw. DC. was studied on seed germination and seedling growth of Acacia nilotica(L. Willd. ex Del., Acacia tortilis (Forssk. Hayne, Cenchrus ciliaris L. and Enteropogon rupestris (J.A. Schmidt A. Chev. Vegetation sampling in different habitat types in the area was made to identify the target plant species. Comparison of canopy characteristics among P. juliflora, A. nilotica and A. tortilis was also made to observe differences if any in canopy closure. P. juliflora was recorded in all habitat types in highest density and observed affecting the plant diversity there in. Its growth characteristics and dense thicket formation restrict light to the ground flora and hence diminishes plant diversity. Leaf, bark and root aqueous extract of P. juliflora at 0, 0.5, 0.8, 1, 2 and 6% wereprepared and their effect studied on germination percentage and seedling growth of the study plant species. Germination of A. nilotica and A. tortilis was not affected by all aqueous extracts of different organ parts of P. juliflora while leaf and root extracts at higher concentrations inhibited germination of C. ciliaris and E. rupestris. Shoot and root growth of the study species were inhibited by leaf and root at higher concentrations. Seed germination of all species except A. nilotica was inhibited by soil amended with decaying plant parts and under canopy soil. The effect is species specific and annuals (grasses and herbs were affected more than perennials. Leaf seems to contain greater number/amount of inhibitors than does root and bark. Bark seems to contain the least. Heavy accumulation of toxic substances at under canopy soil of P. juliflora may be one of the reasons for its invasiveness and low plant diversity.

    2017-01-01

    Background Self-medication patterns vary among different populations, and are influenced by many factors. No review has been done that comprehensively expresses self-medication practice in Ethiopia. The aim of this study was to provide an overview of the literature on self-medication practice in Ethiopia. Materials and methods Databases (PubMed, Google Scholar, ResearchGate, and Hinari) were searched for published studies on the practice of self-medication in Ethiopia without restriction in the year of publication or methodology. Some studies were also identified through manual Google search. Primary search terms were “self medication”, “Ethiopia”, “self care”, “non-prescription”, “OTC drug use”, “drug utilization”, and “drug hoarding”. Studies that measured knowledge only or attitude only or beliefs only and did not determine the practice of self-medication were excluded. Results The database search produced a total of 450 papers. After adjustment for duplicates and inclusion and exclusion criteria, 21 articles were found suitable for the review. All studies were cross-sectional in nature. The prevalence of self-medication varied from 12.8% to 77.1%, with an average of 36.8%. Fever/headache, gastrointestinal tract diseases, and respiratory diseases were the commonest illnesses/symptoms for which self-medication was taken. The major reasons for practicing self-medication were previous experience of treating a similar illness and feeling that the illness was mild. Analgesics/antipyretics, antimicrobials, gastrointestinal drugs, and respiratory drugs were the common drug classes used in self-medication. Mainly, these drugs were obtained from drug-retail outlets. The use of self-medication was commonly suggested by pharmacy professionals and friends/relatives. Conclusion Self-medication practice is prevalent in Ethiopia and varies in different populations and regions of the country. Some of the self-medication practices are harmful and need

  13. Internal migration and household living conditions in Ethiopia

    2006-06-01

    Full Text Available Using the 1998 Migration, Gender and Health Survey in Five Regions of Ethiopia, and multivariate regression techniques, this paper examines the relationship between internal migration and household living conditions. The analysis finds significant living condition advantage of permanent and temporary migrants over non-migrants. These advantages are primarily linked to migration selectivity by education and non-agricultural income. Once the independent effects of these variables are controlled, no statistical significant independent association exists between migration status and living conditions. Government policies of resettlement in the 1980s and ethnic federalism of the 1990s may have engendered stress migration and exacerbated poor living outcomes for return migrants. The resort to migration and/or resettlement as an individual or government policy response to periodic unfavorable conditions in places of origin is not strongly supported by this analysis as the key to improved living conditions. Promoting higher education and opportunities for employment outside the agricultural sector are more likely to yield improved living conditions in Ethiopia.

    In the Afar depression (Ethiopia), extension is already organised along rift segments which morphologically resemble oceanic rifts. Segmentation here results from interactions between dyke injection and volcanism, as observed during the well documented 2005 event on the Dabbahu rift segment. During this tectono-volcanic crisis, a megadyke was injected, followed by 12 subsequent dike intrusions, sometimes associated with fissure flow eruptions. Despite the accurate surveying of the magmatic and tectonic interplay during this event via remote sensing techniques, there is a lack of data on timescales of 1 to 100 kyr, the period over which the main morphology of a rift is acquired. The Dabbahu rift segment represents an ideal natural laboratory to study the evolution of rift morphology as a response to volcanic and tectonic influences. It is possible to constrain the timing of fault growth relative to the infilling of the rift axial depression by lava flows, and to assess the influence of the different magma bodies involved in lava production along the rift-segment. We use cosmogenic nuclides (3He) to determine the ages of young (cartography (Landsat, ASTER and SPOT imagery), the rift geomorphology can be linked to the magmatic and tectonic history defined by surface exposure dating. The results show that over the last 100 ka the Northern part of the Dabbahu segment was supplied by two different magma reservoirs which can be identified based on their distinctive chemistries. The main reservoir is located beneath Dabbahu volcano, and has been supplied with magma for at least 72 ka. This magmatic centre supplies magma to most of the northern third of the rift segment. The second reservoir is located further south, on the axis, close to the current mid-segment magma chamber, which was responsible for the 2005 rifting episode. This second magmatic centre supplies magma to the remaining 2/3 of the segment, but scarcely impacts its Northern termination (where the Dabbahu

    GPS measurements adjacent to the southern Red Sea and Afar Triple Junction, indicate that the Red Sea Rift bifurcates south of 17° N latitude with one branch following a continuation of the main Red Sea Rift (˜150° Az.) and the other oriented more N-S, traversing the Danakil Depression. These two rift branches account for the full Arabia-Nubia relative motion. The partitioning of extension between rift branches varies approximately linearly along strike; north of ˜16°N latitude, extension (˜15 mm/yr) is all on the main Red Sea Rift while at ˜13°N, extension (˜20 mm/yr) has transferred completely to the Danakil Depression. The Danakil Block separates the two rifts and rotates in a counterclockwise sense with respect to Nubia at a present-day rate of 1.9 ± 0.1°/Myr around a pole located at 17.0 ± 0.2°N, 39.7 ± 0.2°E, accommodating extension along the rifts and developing the roughly triangular geometry of the Danakil Depression. Rotating the Danakil Block back in time to close the Danakil Depression, and assuming that the rotation rate with respect to Nubia has been roughly constant, the present width of the Danakil Depression is consistent with initiation of block rotation at 9.3 ± 4 Ma, approximately coincident with the initiation of ocean spreading in the Gulf of Aden, and a concomitant ˜70% increase in the rate of Nubia-Arabia relative motion.

    An estimated 14.3 million people are currently (July 2010) food insecure in Kenya and Ethiopia, and the U.S. government has spent more than $972 million on food aid in these two countries since 2009 (USAID, 2010). This insecurity stems from recent drought and rapid population growth that has outpaced agricultural development (Funk and others, 2008; Funk and Brown, 2009). Previous work by Funk and others (2005, 2008) and Verdin and others (2005) has linked drought conditions in Kenya and Ethiopia with warm sea surface temperatures (SSTs) in the Indian Ocean. Recent work has shown that Indian Ocean SSTs substantially affect rainfall in this region from March through June (Funk and others, 2008; Funk and Verdin, 2009). This season is known as the 'long rains' in Kenya and the 'Belg' rains in Ethiopia.

    Full Text Available Abstract Background Chloroquine is an anti-malarial drug being used to treat Plasmodium vivax malaria cases in Ethiopia. However, emergence of chloroquine resistant strains of the parasite has challenged the current efficacy of the drug. Therefore, the aim of this study was to assess the effectiveness of chloroquine against P. vivax strains in one of the malaria endemic areas of Ethiopia, namely Halaba district, located in South Nations and Nationalities Peoples Region (SNNPR of South Ethiopia Results Among 87 malaria patients enrolled in the study, only 80 of them completed the 28-days follow-up. Seven of them dropped from the study for different reasons. Among those study participants that completed their follow-up, 69 were classified under the category of adequate clinical and parasitological response (ACPR. However, the remaining 11 cases were considered as under treatment failure mainly due to recurrence of parasitemia on day 7 (four patients, day 14 (six patients, and day 21 (one patient. The age of all cases of treatment failures was found to be less than 20 years. The load of parasitemia of patients with treatment failure on day of admission (4709.4/μl was higher than day of recurrence (372.37/μl. Parasite reduction ratio (PRR of treatment failure cases was 12.6/μl. Conclusion This report revealed the rise in treatment failure (13% [95% CI = 0.074 - 0.217] as compared to earlier reports from Ethiopia. It signals the spreading of chloroquine resistant P. vivax (CRPv strains to malaria endemic areas of Ethiopia. It is recommended that all concerned bodies should act aggressively before further expansion of the current drug resistant malaria.

    Nabro volcano sits on the southern part of Danakil block to the east of the Afar depression, on the Arabian plate. On the 12th June 2011, Nabro volcano suddenly erupted after being inactive for 10,000 years. The eruption caused a 17-km-long lava flow, a 15-km-high ash cloud, and ranks as one of the largest emissions of SO2 since the Mt. Pinatubo (1991) event. This eruption creates an important opportunity to use seismicity and surface deformation measurements to understand the subsurface magmatic system and deformation of a hazardous, off axis caldera during continental rupture. We installed a network of 8 seismometers around Nabro caldera which began recording on the 31st August and tasked SAR acquisitions from TerraSAR-X (TSX) and Cosmo-SkyMed (CSK) satellites. The SAR images used for this study post date the eruption. We used TSX stripmap mode images from ascending and descending orbits. Using a small baseline approach, we used 25 images acquired between the 1st July 2011 to the 5th October 2012 on descending orbit 046, to create 34 interferograms. We complemented these with 19 images from ascending orbit 130 spanning the 6th July 2011 to the 10th October 2012 from ascending orbit 130, which we used to create 21 interferograms. We produced a velocity ratemap and timeseries using π-RATE showing subsidence of up to 25cm/yr centred on Nabro. We used a Monte-Carlo hybrid downhill simplex technique to invert the dataset and found the best fitting solution as a mogi source at 6.9 ±1.1 km depth, and located at a 13.35 (lat) and 41.69 (long). The time dependence observed is consistent with a viscoelastic relaxation around the magma chamber, following depletion. Concurrent with the TSX acquisitions, CSK imaged the volcano on a descending track between 26th June 2011 and 18th July 2012 within the ASI project SAR4Volcanoes, and 64 images were used to produce 171 interferograms which were inverted to form a timeseries using a SBAS approach. This dataset has an overall

    The bi-modal climate of SE Ethiopia shares attributes with East Africa, notably that El Niño enhances rainfall, particularly in Sep-Nov season. In this study SE Ethiopia's continuous and seasonal rainfall relationships to global climate are studied to extend our knowledge of its determinants and predictability. A statistical forecast algorithm for the Sep-Nov short rains accounts for 54% of variance in 1980-2010. The Apr-Jun predictors include South Atlantic sea surface temperature, east Indian Ocean sea level air pressure and China upper zonal wind. Cooling in the South Atlantic coincides with a strengthened sub-tropical anticyclone, and later to changes in low level winds that bring orographic convection to SE Ethiopia. The slower El Niño-Southern Oscillation (ENSO) interacts with the faster Indian Ocean Dipole (IOD), but both signals mature too late for direct use in statistical prediction of Sep-Nov rainfall. Composite differences of the upper divergent circulation exhibit a global wave-2 pattern consistent with satellite-observed convection. One key feature is a zonal gradient in upper velocity potential over the Indian Ocean corresponding with a zonal atmospheric circulation. One outcome of this research is useful forecasts of SE Ethiopia Sep-Nov rainfall that will assist in agricultural planning.

    The rates of congenital and genetic disorders in low and middle income countries are similar or might be higher than in high income countries due to a multitude of risk factors and the dearth of community genetic services. To direct effective preventive, diagnostic and counseling services, collecting data on the incidence and prevalence of various congenital and genetic disorders and their risk factors is a pre-requisite for establishing genetic services at the community level and mainly at the primary health care setting. This brief review is meant to assess the available epidemiological data in Ethiopia pertaining to congenital and genetic disorders on which the future community genetic services could be built. Existing epidemiological data on congenital and genetic disorders in Ethiopia is limited, and the few studies conducted revealed that folate and iodine deficiencies are prevalent among women in the reproductive age. Pregnant women's infection with syphilis and rubella is prevailing. Based on available data, cleft lip and palate, congenital heart diseases, club-foot, and gastro-intestinal malformations are the most common birth defects in Ethiopia. Community based studies to accurately demonstrate the incidence and prevalence levels of these disorders are almost unavailable. To plan for organization and implementation of community genetic services at the primary health care level in Ethiopia, conducting standardized epidemiological studies is currently highly recommended.

    Full Text Available This paper identified and examined saving behaviour and determinants of saving mobiliza-tion by the rural co-operators in Southern Tigrai Ethiopia. The input for the study was ob-tained from randomly selected 120 rural household savers from six purposively selected ru-ral savings and credit cooperatives. The result of the study using least squares method showed that savings mobilized is determined by household annual income, amount of loan borrowed and year of member stay in the cooperative. These factors therefore have to be considered in designing strategies aimed at improving the saving mobilization of coopera-tive members in the study area. Besides, economically feasible cooperative societies in the region should be encouraged among the rural households by supporting them with revolv-ing funds as they are more effective and efficient in mobilizing rural savings and provide collateral plus guarantor-based loans with low default rate. This will enable them to boost up their production output and increase their savings thereby stimulating the rural economy.

    The study was conducted in three regional states of Ethiopia: Amhara, Oromia, and the Southern Nations Nationalities and people regional state from August 2007 to April 2008 with the objective of identifying the foot and mouth disease virus (FMDV) serotypes circulating in the region. Two serotypes were recorded from epithelial tissue and oesophageal-pharyngeal (OP) fluid that were taken from outbreaks in study regions of Ethiopia. Serotype O FMDV was identified in Girar Jarso, Yabello, and Ankesha Guagusa districts while SAT-1 was isolated in Surma and Maji districts from tissue samples and this was the first report of the FMDV serotype in Ethiopia. Similarly, the OP fluid samples were found positive for SAT-1 FMDV in Maji and Surma districts.

    Mange mites are economically important ectoparasites of sheep and goats responsible for rejection or downgrading of skins in tanneries or leather industries in Ethiopia. The objective of this systematic review was to compute the pooled prevalence estimate and identify factors influencing mange mite prevalence in sheep and goats at national level based on the available research evidence. Articles on mange mite infestation of small ruminants in Ethiopia were searched in PubMed, Web of Science, Google scholar and African journals on-line. The review was based on 18 cross-sectional studies carried out between 2003 and 2015 in four administrative states of Ethiopia. Accordingly, the pooled prevalence estimate in a random effects meta-analysis was estimated to be 4.4% (95% CI 3.0, 6.3) although there were evidence of a substantial amount of between-study variance (I(2)=98.4%). In subgroup and multivariable meta-regression analyses, animal species, agro-ecology and administrative state were found to have significant effect on the prevalence estimate (Pagro-ecology. Region wise the highest estimate was calculated for Amhara (6.4%) followed by Oromia (4.7%), Tigray (3.6%) and Southern Nations, Nationalities and People Region (SNNPR) (3.1%). Significant difference was noted between Amhara and SNNPR. The study further revealed that mites of the genus Sarcoptes, Demodex and Psoroptes are the most prevalent mites infesting small ruminants in Ethiopia. Valid studies were lacking from five regional states. As some of these regions are known for their large small ruminant population, further studies are warranted to produce better picture of the infestation at a national level. Meanwhile, the need for monitoring the ongoing control intervention is suggested.

Despite the government’s measures to ensure institutional delivery assisted by skilled attendants, home delivery remains high, estimated at over 80% of all pregnant women.Objective: The study aims to identify determinants that sustain home delivery in Ethiopia.Methods: A total of 48 women who delivered their most recent child at home, 56 women who delivered their most recent child in a health facility, 55 husbands of women who delivered within 1 year preceding the study, and 23 opinion leaders in selected districts of Amhara, Oromia, Southern Nations, Nationalities, and Peoples’ Region, and Tigray regions were involved in the study. Key informant interview, in-depth interviews, and focus group discussions were conducted to collect data using checklists developed for this purpose. Data reduction and analysis were facilitated by Maxqda qualitative data analysis software version 11.Results: Findings show that pregnancy and delivery is a normal and natural life event. Research participants unanimously argue that such a life event should not be linked with health problems. Home is considered a natural space for delivery and most women aspire to deliver at home where rituals during labor and after delivery are considered enjoyable. Even those who delivered in health facilities appreciate events in connection to home delivery. Efforts are underway to create home-like environments in health facilities, but health facilities are not yet recognized as a natural place of delivery. The positive tendency to deliver at home is further facilitated by poor service delivery at the facility level. Perceived poor competence of providers and limited

    2008-01-01

    Until the turn of the 20th century, only the religious and political elite of the city of Harer in eastern Ethiopia chewed khat. Its consumption has since spread to all regions of Ethiopia and all social groups, irrespective of religious affiliation, gender category, and age bracket, have taken up the habit. In a few decades khat has been transformed from a shrub grown for domestic consumption to the region's predominant cash crop; from a substance chewed on religious and cultural occasions to a visible and pervasive social habit; from a product sold in local markets to the most profitable commodity, whose trade involves millions of farmers, traders, and other service providers in the Horn of Africa and the Arabian Peninsula. The growing importance of khat has engendered a heated national debate in Ethiopia concerning the legal status of the plant. Opponents contend that khat is a health hazard with deleterious socioeconomic consequences and seek a complete ban to curb its "evil influence" on the country's youth and future. Others oppose any policy that ignores khat's micro- and macroeconomic benefits. This article outlines the positions the protagonists in this debate have staked out, critically evaluates their merits, and concludes by urging a public discourse on how to use the prosperity that the khat industry has generated to engender a sustainable economic development.

    This meta-analysis estimates a single-group summary (effect size) for seroprevalence of Brucella spp. exposure in dairy cattle of Ethiopia. It also attempts to identify study-level variables that could explain the variation in apparent seroprevalence. The literature search was restricted to studies published in English language from January 2000 to December 2013. A template was designed to retrieve the most biologically plausible and consistent variables from the articles. A total of 29 published papers containing 40 animal-level studies were used in the analyses. The single-group summary of Brucella seroprevalence in cattle was estimated to reach 3.3 % with 95 % confidence interval (CI) (2.6-4.2 %). Of all the variables considered, region was the only specific factor identified to explain about 20 % of between-study variation. Accordingly, the region-based meta-analysis forest plot revealed the highest prevalence in central Ethiopia followed by southern part. The lowest prevalence estimate was observed in the western part of the country. The visual inspection of the funnel plot demonstrated the presence of possible publication bias which might dictate shortage of studies with higher prevalences or variance inflation due to infectiousness of Brucella. In conclusion, the quantitative review showed the seroprevalence to be low but widely distributed. More importantly, the review underscores the need for isolation and characterization of the circulating Brucella spp. to capture the type of Brucella spp. involved and its distribution in cattle in Ethiopia.

    Full Text Available BACKGROUND: Podoconiosis is a neglected tropical disease (NTD that is prevalent in red clay soil-covered highlands of tropical Africa, Central and South America, and northern India. It is estimated that up to one million cases exist in Ethiopia. This study aimed to estimate the prevalence of podoconiosis in East and West Gojam Zones of Amhara Region in northern Ethiopia. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional household survey was conducted in Debre Eliyas and Dembecha woredas (districts in East and West Gojam Zones, respectively. The survey covered all 17,553 households in 20 kebeles (administrative subunits randomly selected from the two woredas. A detailed structured interview was conducted on 1,704 cases of podoconiosis identified in the survey. RESULTS: The prevalence of podoconiosis in the population aged 15 years and above was found to be 3.3% (95% CI, 3.2% to 3.6%. 87% of cases were in the economically active age group (15-64 years. On average, patients sought treatment five years after the start of the leg swelling. Most subjects had second (42.7% or third (36.1% clinical stage disease, 97.9% had mossy lesions, and 53% had open wounds. On average, patients had five episodes of acute adenolymphangitis (ALA per year and spent a total of 90 days per year with ALA. The median age of first use of shoes and socks were 22 and 23 years, respectively. More men than women owned more than one pair of shoes (61.1% vs. 50.5%; χ(2 = 11.6 p = 0.001. At the time of interview, 23.6% of the respondents were barefoot, of whom about two-thirds were women. CONCLUSIONS: This study showed high prevalence of podoconiosis and associated morbidities such as ALA, mossy lesions and open wounds in northern Ethiopia. Predominance of cases at early clinical stage of podoconiosis indicates the potential for reversing the swelling and calls for disease prevention interventions.

    Although hepatitis B virus (HBV) infection is hyperendemic in Ethiopia and constitutes a major public health problem, little is known about its genetic diversity, genotypes, and circulation. The aim of this study was to determine the molecular epidemiology and genetic diversity of HBV in Ethiopia, using 391 serum samples collected from HBsAg-positive blood donors living in five different geographic regions. The HBV S/pol gene was amplified, sequenced, and HBV genotypes, subgenotypes, serotypes, and major hydrophilic region (MHR) variants were determined. Phylogenetic analysis of 371 samples (95%) revealed the distribution of genotypes A (78%) and D (22%) in Ethiopia. Further phylogenetic analysis identified one subgenotype (A1) within genotype A, and 4 subgenotypes within genotype D (D1; 1.3%, D2; 55%, D4; 2.5%, and D6; 8.8%). Importantly, 24 isolates (30%) of genotype D formed a novel phylogenetic cluster, distinct from any known D subgenotypes, and two A/D recombinants. Analysis of predicted amino-acid sequences within the HBsAg revealed four serotypes: adw2 (79%), ayw1 (3.1%), ayw2 (7.8%), and ayw3 (11.6%). Subsequent examination of sequences showed that 51 HBV isolates (14%) had mutations in the MHR and 8 isolates (2.2%) in the reverse transcriptase known to confer antiviral resistance. This study provides the first description of HBV genetic diversity in Ethiopia with a predominance of subgenotypes A1 and D2, and also identified HBV isolates that could represent a novel subgenotype. Furthermore, a significant prevalence of HBsAg variants in Ethiopian population is revealed.

    2014-10-01

    The introduction and development of psychology in Ethiopia has been mainly limited to Addis Ababa University in the capital city, and also to educational and school psychology which was highly influenced by the field of education at this pioneering university. Similarly, mental health services have been principally developed at the Amanuel Mental Hospital in Addis Ababa that has existed since the 1950s. However, the expansion of higher learning institutions on one hand, and the apparent growing prevalence of mental illness on the other, seem to have contributed to the development of both mental health training and services in other regional cities and towns. Although the influence of the education-oriented psychological training of the Addis Ababa University is still present, clinical psychology education and services are now being started in other universities. One of these is the master's programme in clinical psychology opened for the first time in the University of Gondar. This article sheds light on the development of psychology in Ethiopia and addresses some of the issues raised about the factors that have influenced its development such as traditional beliefs, poverty and comparisons between mental health in lower middle-income countries and higher middle-income countries ( Uppal et al., 2014 ). The paper also proposes future directions for the education, research, infrastructure and services of clinical psychology and mental health in Ethiopia.

    Full Text Available Household food security issues have become the concern of international communities as well as national government of Ethiopia. Social safety nets (like Productive Safety Net Program in Ethiopia are programs that offer protection to poor rural people by providing income through transfer programs and employment opportunities. The main objective of this study was to identify the major graduation determinants of Productive safety Net Program beneficiary rural households using a logistic regression technique from a total of 400 sample respondents using Eastern zone of Tigrai regional national state, northern Ethiopia, as case study site. The researcher was initially identified about sixteen predicting factors of which just ten of them were found to be statistically significant, and all exhibited the expected signs. Regression results revealed thatan introduction to integrated agricultural package make use of, male-headed household, age squared of the household head, educational status of the household head, saving culture, male adults, non-government organizations follow-up, access to credit, access to petty trading and irrigation have led productive safety net program beneficiary households to have more probability of graduation. Finally, it is recommended that assisting farming rural households to diversify and expand their sources of income in order to be able to meet their minimum food requirement and graduate soon through the provision of integrated agricultural packages. Besides, program participants should be followed up by non-government organizations and highly engaged in petty trading to graduate sooner, boost their income and food secure.

    1988-10-01

    Ethiopia is a country of 45 million people in northeast Africa. With a stagnant, agriculture-based economy and a per capita gross national product of $110 in 1984, it is one of the world's poorest nations. 70% of the children are mildly to severely malnourished, and 25.7% of children born alive die before the age of 5. Life expectancy is 41 years. The population is growing at the rate of 2.9%/year, but only 2% of the people use birth control. After the 1974 revolution, the socialist government nationalized land and created 20,000 peasant associations and kebeles (urban dwellers' associations), which are the units of local government. The government has set ambitious goals for development in all sectors, including health, but famine, near famine, forced resettlement programs, and civil war have prevented any real progress from being made. The government's approach to health care is based on an emphasis on primary health care and expansion of rural health services, but the Ministry of Health is allocated only 3.5% of the national budget. Ethiopia has 3 medical schools -- at Addis Ababa, Gondar, and the Jimma Institute of Health Sciences. Physicians are government employees but also engage in private practice. A major problem is that a large proportion of medical graduates emigrate. Ethiopia has 87 hospitals with 11,296 beds, which comes to 1 bed per 3734 people. There are 1949 health stations and 141 health centers, but many have no physician, and attrition among health workers is high due to lack of ministerial support. Health care is often dispensed legally or illegally by pharmacists. Overall, there is 1 physician for 57,876 people, but in the southwest and west central Ethiopia 1 physician serves between 200,000 and 300,000 people. In rural areas, where 90% of the population lives, 85% live at least 3 days by foot from a rural health unit. Immunization of 1-year olds against tuberculosis, diphtheria-pertussis-tetanus, poliomyelitis, and measles is 11, 6, 6, and

  8. Reconfiguring Ethiopia: The Politics of Authoritarian Reform

    DEFF Research Database (Denmark)

    reconfigured Ethiopian society and state in the past two decades. Yet, as the contributors to this volume demonstrate, ‘democracy’ in Ethiopia has not changed the authority structures and the culture of centralist decision-making of the past. The political system is tightly engineered and controlled from top...... to bottom by the ruling Ethiopian Peoples’ Revolutionary Democratic Front (EPRDF). Navigating between its 1991 announcements to democratise the country and its aversion to power-sharing, the EPRDF has established a de facto one-party state that enjoys considerable international support. This ruling party...

    Background Understanding the geographical distribution of multidrug-resistant tuberculosis (MDR-TB) in high TB burden countries such as Ethiopia is crucial for effective control of TB epidemics in these countries, and thus globally. We present the first spatial analysis of multidrug resistant tuberculosis, and its relationship to socio-economic, demographic and household factors in northwest Ethiopia. Methods An ecological study was conducted using data on patients diagnosed with MDR-TB at the University of Gondar Hospital MDR-TB treatment centre, for the period 2010 to 2015. District level population data were extracted from the Ethiopia National and Regional Census Report. Spatial autocorrelation was explored using Moran’s I statistic, Local Indicators of Spatial Association (LISA), and the Getis-Ord statistics. A multivariate Poisson regression model was developed with a conditional autoregressive (CAR) prior structure, and with posterior parameters estimated using a Bayesian Markov chain Monte Carlo (MCMC) simulation approach with Gibbs sampling, in WinBUGS. Results A total of 264 MDR-TB patients were included in the analysis. The overall crude incidence rate of MDR-TB for the six-year period was 3.0 cases per 100,000 population. The highest incidence rate was observed in Metema (21 cases per 100,000 population) and Humera (18 cases per 100,000 population) districts; whereas nine districts had zero cases. Spatial clustering of MDR-TB was observed in districts located in the Ethiopia-Sudan and Ethiopia-Eritrea border regions, where large numbers of seasonal migrants live. Spatial clustering of MDR-TB was positively associated with urbanization (RR: 1.02; 95%CI: 1.01, 1.04) and the percentage of men (RR: 1.58; 95% CI: 1.26, 1.99) in the districts; after accounting for these factors there was no residual spatial clustering. Conclusion Spatial clustering of MDR-TB, fully explained by demographic factors (urbanization and percent male), was detected in the border

    Little work has been done on diseases of horses in Ethiopia or tropical regions of the world. Yet, Ethiopia has the largest horse population in Africa and their horses play a pivotal role in their economy as traction animals. A serological and questionnaire survey was therefore conducted to determine the circulating serovars of Leptospira and their association with potential risk factors in the cart horse population of Central and Southern Ethiopia. A total of 184 out of 418 cart horses from 13 districts had antibody titres of 1:100 or greater to at least one of 16 serovars of Leptospira species in Central and Southern Ethiopian horses. A significantly higher seropositivity (62.1%) was noted in horses from the highland agroecology followed by midland (44.4%) and lowland (39.8%). Serovar Bratislava (34.5%) was the predominant serovar followed by serovars Djasiman (9.8%), Topaz (5.98%) and Pomona (5.3%). Age and location proved to be associated with seropositive horses with older horses being more commonly affected and the districts of Ziway (Batu) (Apparent Prevalence (AP)=65.5%), Shashemene (AP=48.3%) and Sebeta (AP=41.4%) having the highest prevalence. Multivariable logistic regression found risk factors significantly associated with Leptospira seropositive horses were drinking river water (OR=2.8) and horses 7-12 years old (OR=5) and risk factors specifically associated with serovar Bratislava seropositive horses were drinking river water (OR=2.5), horses ≥13 years (OR=3.5) and the presence of dogs in adjacent neighbouring properties (OR=0.3). Dogs had a protective effect against seropositivity to serovars Bratislava and Djasiman, which may be due to their ability to control rodents. The high seroprevalence confirm that leptospirosis is endemic among horses of Central and Southern Ethiopia. The predominance of serovar Bratislava supports the idea that serovar Bratislava may be adapted to and maintained by the horse population of Central and Southern Ethiopia

    A census and an ecologic survey were performed in 39 villages of a rural district of Arsi Region, Ethiopia, in difficult field circumstances. Information on age, ethnic group, education and family relationship, as well as data on health facilities and availability of basic services were collected. Supervised students, working in teams, were used as interviewers. Communities were involved through plenary meetings and community health agents participated in the data collection process. A total of 64,714 people in 12,152 households were registered. The repeatability of age assessment was investigated by comparing the results from two villages with data obtained in a pilot study carried out 6 months earlier. The technical error was only 0.80 and 1.67 in the 0-5 and 6-15 age-groups, respectively. Three percent of the total population was under one year, less than previously estimated. This may, in part, be due to the family planning programme in the region. Eighteen percent of the households were headed by females. School attendance was less common among females and in the Oromo ethnic group. The availability of basic services, including safe water and basic sanitation supplies, was very poor in the area.

    Full Text Available Background: Global mental health (GMH advocates for access to and the equitable provision of mental health care. Although the treatment gap is a useful construct to measure access and equitability of care, it fails to communicate the real-life consequences of the treatment gap and the urgent need to address care disparities. Objective: The aim of this article is to present a perspective on the practical application of the principles of GMH to understand the real-life impact of the treatment gap and the approaches taken to improve treatment coverage in Ethiopia. Design: A case study method is used. Results: Multiple international collaborations undertaken in Ethiopia and facilitated by GMH to improve care, capacity, and the evidence base for increased treatment coverage are described briefly. A series of steps taken at the local and national levels to address the treatment gap are highlighted. The stories of two patients are also presented to illustrate the real-life consequences of the treatment gap and the potential transformational impact of addressing the treatment gap on patients, families, and communities. Conclusions: GMH has a key role to play in addressing the treatment gap, which improves the life of people with mental disorders, their families, and their communities. However, national-level policy support and coordination are essential for any realistic improvement in treatment coverage. The reflections offered through the case examples may have utility in similar low-income settings.

    Land degradation is a great threat for the future and it requires great effort and resources to ameliorate. The major causes of land degradation in Ethiopia are the rapid population increase, severe soil loss, deforestation, low vegetative cover and unbalanced crop and livestock production. Inappropriate land-use systems and land-tenure policies enhance desertification and loss of agrobiodiversity. Utilization of dung and crop residues for fuel and other uses disturbs the sustainability of land resources. The supply of inputs such as fertilizer, farm machinery and credits are very low. The balance between crop, livestock, and forest production is disturbed, and the farmer is forced to put more land into crop production. For environmentally and socially sustainable development, there is an urgent need to promote awareness and understanding of the interdependence of natural, socioeconomic, and political systems at local and national levels. Understanding the current status and causes of land degradation is very important. This paper reveals the important elements of land degradation in Ethiopia and suggests possible solutions that may help to ameliorate the situation.

    2016-01-01

    Background Female genital mutilation (FGM) is a worldwide problem, and it is practiced by many communities in Africa and Asia as well as immigrants from those areas. This practice results in short- and long-term health consequences on women’s health. Like many other developing countries, FGM is widely practiced in Ethiopia, especially among Somali and Harari ethnic groups. Despite intensive campaigns against FGM in Ethiopia, since 2011, it has been practiced in the aforementioned communities. There is no recent information as to whether these campaigns have an impact on the attitude and practice of the community regarding FGM. This qualitative research was aimed at exploring the attitudes of Somali and Harari people between 18 and 65 years toward FGM. Methods A purposive sampling technique was used to recruit 64 (32 in each region) participants. Data were collected from October to December 2015 in Somali and Harari Regions. Results The findings showed that there was a strong support for the continuation of the practice among female discussants in Somali region, whereas male discussants from the same region and the majority of the participants from Harari region had a positive attitude toward the discontinuation of the practice. Marriageability was the major reason for practicing FGM in Somali region, whereas making girls calm, sexually inactive, and faithful for their husbands were mentioned in Harari region. Although young men in both the regions prefer to marry uncircumcised girls, the study showed that there are some differences in the attitude toward the FGM practice between the people in the two regions. Conclusion The findings show that there is an attitudinal difference between the people in the two regions, which calls for behavioral change communication using women-centered approach and culturally appropriate strategies. As young people in both the regions had the intention to marry uncircumcised girls, there has to be a strong advocacy and multisectoral

    Full Text Available In a review of their own research the authors summarize incidences and distributions of the most important fungal diseases in Ethiopia and progress in breeding for resistance. Ethiopia, as the centre of origin for Coffea arabica, hosts a large diversity of germplasm. The incidences of diseases are based on observations in the montane rainforests of the southeast (Harenna and southwest (Bonga, Berhane-Kontir, Yayu of Ethiopia. Major diseases are Coffee Leaf Rust (CLR, Hemileia vastatrix; Coffee Berry Disease (CBD, Colletotrichum kahawae and Coffee Wilt Disease (CWD, Gibberella xylarioides (Fusarium xylarioides. CLR incidences in Ethiopia were present in all regions with highs between January and March and lows between June and October. CBD was present mostly in Bonga (40.0% and Yayu (26.3%, but less frequent in Harenna (18.6% and Berhane-Kontir (6.0%. CWD as a recently developed disease in Arabica coffee could be detected ranging from 2.4% in Berhane-Kontir to 16.9% in Yayu. CLR has been a serious constraint in all production countries since it became prominent in Ceylon in the late 19th century after leaf infection defoliation affects plants. CBD was first observed in Kenya in 1922. The disease is currently confined to the African continent in all countries that grow Arabica coffee. In the mid-1990s in the Democratic Republic of Congo, Uganda and Tanzania a resurgence of CWD in Robusta coffee and in Ethiopia in Arabica coffee occurred. Over the last 40 years breeding activities have been carried out to combat CLR, CBD and CWD. Breeding for resistance against CLR in Arabica coffee has successfully utilized single or combinations of major genes designated as SH genes. Major gene resistance has also been deployed in breeding for resistance against CBD, whereas in the case of CWD, selections of tolerant Arabica accessions are being pursued from local landraces in Ethiopia.

    Objective: Globally, the number of people living with human immunodeficiency virus (PLHIV) particularly in sub-Saharan Africa is growing. This has been resulted in increased number of tuberculosis (TB) new cases. To control burden of TB among PLHIV, a number of collaborative TB/HIV activities were recommended. However, data about collaborative TB/HIV services in the study area is scarce. The objective of this study is to assess intensified TB case finding, implementation of isoniazid preventive therapy (IPT) and associated factors among PLHIV. Methods: A facility based cross-sectional study design was employed among 419 randomly selected PLHIV from public health facilities of Harari region. Systematic sampling method was used to obtain sample from each health facilities. Interviewer-administered questionnaire was used to collect data. Data were entered into EpiData and analyzed by SPSS statistical software. Multivariate logistic regression analysis was conducted to determine the presence of association between variables using odds ratio with 95% confidence interval and association was declared significant at P ≤ 0.05. Results: One hundred fifteen (75.2%) of the respondents reported that they offered screening for TB during their HIV chronic cares and 94 (29.8%) of them were found to be positive for active TB. Female sex [AOR 2.51; 95%CI (1.52, 6.14)], educated patients [AOR 0.52; 95%CI (0.21, 0.83)], CD4 count greater than 350 cells/dl3 [AOR 0.62; 95%CI(0.22,0.82)], Antiretroviral Therapy (ART) initiation [AOR 0.50; 95%CI (0.35, 0.88)] and missing dose of ART [AOR 2.57; 95%CI (1.21, 5.32)] were significantly associated with TB infection. Nearly four-fifth (78.7 %) of the study participants were provided IPT. Conclusions: Screening of TB among PLHIV and implementation of IPT in the region is lower when compared to the findings of other studies conducted in different parts of the country and needs to be improved through implementation of national and international

    Dilla is a socio-economically important town in Ethiopia, established on the international highway joining capital cities of Ethiopia and Kenya. It serves as an administrative center of the Gedeo Zone in SNNPR region of Ethiopia accommodating around 65000 inhabitants and also as an important trade centre for coffee. Due to the recent developments and urbanization in town and surrounding area, waste and sewage discharge has been raised significantly into the water resources. Also frequent rainfall in the region worsens the problem of water quality. In this view, present study aims to analyze water quality profile of Dilla town using 12 physico-chemical parameters. 15 Sampling stations are identified amongst the open wells, bore wells and from surface water, which are being extensively used for drinking and other domestic purposes. Spectrophotometer is used to analyze data and Gaussian process regression is used to interpolate the same in GIS environment to represent spatial distribution of parameters. Based on observed and desirable values of parameters, water quality index (WQI); an indicator of weighted estimate of the quantities of various parameters ranging from 1 to 100, is developed in GIS. Higher value of WQI indicates better while low value indicates poor water quality. This geospatial analysis is carried out before and after rainfall to understand temporal variation with reference to rainfall which facilitates in identifying the potential zones of drinking water. WQI indicated that 8 out of 15 locations come under acceptable category indicating the suitability of water for human use, however remaining locations are unfit. For example: the water sample at main_campus_ustream_1 (site name) site has very low WQI after rainfall, making it unfit for human usage. This suggests undertaking of certain measures in town to enhance the water quality. These results are useful for town authorities to take corrective measures and ameliorate the water quality for human

    Noroviruses (NoVs) and sapoviruses (SaVs), which belong to the family Caliciviridae, are important human and animal enteric pathogens with zoonotic potential. In Ethiopia, no study has been done on the epidemiology of animal NoVs and SaVs. The aim of this study was to detect and characterize NoVs and SaVs from swine of various ages. Swine fecal samples (n = 117) were collected from commercial farms in Ethiopia. The samples were screened for caliciviruses by reverse transcription polymerase chain reaction (RT-PCR) using universal and genogroup-specific primer pairs. Phylogenetic analysis was conducted using a portion of the RNA-dependent RNA polymerase (RdRp) region and the VP1 region of genome sequences of caliciviruses. Among 117 samples, potential caliciviruses were detected by RT-PCR in 17 samples (14.5 %). Of the RT-PCR-positive fecal samples, four were sequenced, of which two were identified as human NoV GII.1 and the other two as porcine SaV GIII. The porcine SaV strains that were detected were genetically related to the porcine enteric calicivirus Cowden strain genogroup III (GIII), which is the prototype porcine SaV strain. No porcine NoVs were detected. Our results showed the presence of NoVs in swine that are most similar to human strains. These findings have important implications for NoV epidemiology and food safety. Therefore, continued surveillance of NoVs in swine is needed to define their zoonotic potential, epidemiology and public and animal health impact. This is the first study to investigate enteric caliciviruses (noroviruses and sapoviruses) in swine in Ethiopia.

    2008-09-01

    Full Text Available Abstract Background Peste des petits ruminants (PPR is a contagious viral disease of small ruminants in Africa and Asia. In 1999, probably the largest survey on PPR ever conducted in Africa was initiated in Ethiopia where 13 651 serum samples from 7 out of the 11 regions were collected and analyzed by competitive enzyme-linked immunosorbent assay (cELISA. The objective of this paper is to present the results of this survey and discuss their practical implications for PPR-endemic regions. Methods We explored the spatial distribution of PPR in Ethiopia and we investigated risk factors for positive serological status. Intracluster correlation coefficients (ρ, were calculated for 43 wereda (administrative units. Results Seroprevalence was very heterogeneous across regions and even more across wereda, with prevalence estimates ranging from 0% to 52.5%. Two groups of weredas could be distinguished on the basis of the estimated ρ: a group with very low ρ (ρ 0.37. Conclusion The results indicate that PPRV circulation has been very heterogeneous, the values for the ρ may reflect the endemic or epidemic presence of the virus or the various degrees of mixing of animals in the different areas and production systems. Age appears as a risk factor for seropositive status, the linear effect seeming to confirm in the field that PPRV is highly immunogenic. Our estimates of intracluster correlation may prove useful in the design of serosurveys in other countries where PPR is of importance.

  7. Trend analysis of extreme precipitation in the Northwestern Highlands of Ethiopia with a case study of Debre Markos

    Full Text Available Understanding extreme precipitation is very important for Ethiopia, which is heavily dependent on low-productivity rainfed agriculture but lacks structural and non-structural water regulating and storage mechanisms. There has been an increasing concern about whether there is an increasing trend in extreme precipitation as the climate changes. Existing analysis of this region has been descriptive, without taking advantage of the advances in extreme value modeling. After reviewing the statistical methodology on extremes, this paper presents an analysis based on the generalized extreme value modeling with daily time series of precipitation records at Debre Markos in the Northwestern Highlands of Ethiopia. We found no strong evidence to reject the null hypothesis that there is no increasing trend in extreme precipitation at this location.

    Ethiopia is climatically and environmentally extremely heterogeneous. The highlands receive a lot of rainfall (more than 2000 mm/year) concentrated in only three months. Most of Ethiopian runoff is produced in these highlands (part of this water reaches the Mediterranean sea through the Nile river). Lowlands vary from forests to deserts. The hottest place on earth is there (the Danakil depression, more than 150 meters below see level). This makes the spatial and temporal variability of hydrologic signatures very strong in the country. We present the results of a comparative hydrology exercise performed during a three-week Winter Research Workshop held in Addis Ababa during Christmas time this year. There, a new institution, the Ethiopian Institute of Water Resources (EIWR), and a new education program (18 PhD + 24 MSc) has been started less than one year ago. Instead of the traditional approach of education, based on lectures, reading and exercises, a learner-centered approach has been used: the students have been asked to collect available rainfall and runoff data, to interpret them by comparing and contrasting different catchments in the country, to develop conceptual models and use them to critically test ideas. The R software has been used in the workshop for two reason: (1) its flexibility makes it an ideal language for learner-centered education, since students can easily define new functions and extensions and can autonomously develop and test their hypothesis; (2) it is open source, light and free of charge, which makes it particularly appealing in developing countries like Ethiopia.

    1994-01-01

    In comprehensive efforts to rehabilitate the shattered social and economic structure and to lay down a strong foundation for sustainable development, the Transitional Government of Ethiopia (TGE) has officially adopted a National Population Policy on July 12, 1993. The major goals of the newly adopted National Population Policy (NPP) include the harmonization of the rate of population growth with the capacity of the country for development, and the rational utilization of resources, thereby creating conditions conducive to the improvement of the welfare of the population. Thus, the NPP will be pursuing the following objectives: 1) closing the gap between high population growth and low economic productivity through planned reduction of population growth and increasing economic returns; 2) expediting economic and social development processes through holistic, integrated development programs designed to expedite the structural differentiation of the economy and employment; 3) reducing the rate of rural to urban migration; 4) maintaining/improving the carrying capacity of the environment by taking appropriate environmental protection/conservation measures; 5) raising the economic and social status of women by freeing them from the restrictions and drudgeries of traditional life and making it possible for them to participate productively in the larger community; 6) significantly improving the social and economic status of vulnerable groups (women, youth, children, and the elderly). The task of harmonizing the rate of population growth with the tempo of economic and social development requires the involvement and collaboration of a number of governmental and nongovernmental agencies. The UNFPA Governing Council had approved the allocation of 95 million Ethiopian Birr to Ethiopia. This assistance may be increased in the next few years if the financial situation permits.

    The experiment was conducted to determine the supplementary feeding value of ground Prosopis juliflora pod (Pjp) and cottonseed meal (CSM) and their mixtures on feed intake, body weight gain and carcass parameters of Afar sheep fed a basal diet of pasture hay. Twenty-five yearling fat-tailed Afar rams with mean initial live weight 17.24 ± 1.76 kg (mean ± SD) were used in a randomized complete block design. Animals were blocked on their initial body weight. The experiment was conducted for 12 weeks and carcass evaluation followed. Treatments were hay alone ad libitum (T 1) or with 300 g CSM (T 2), 300 g Pjp (T 5), 2:1 ratio (T 3) and 1:2 ratio of CSM : Pjp (T 4). The CP contents of the hay, CSM and Pjp were 10.5, 44.5 and 16.7 %, respectively. Hay DM intake was higher (P < 0.05) for non-supplemented and total DM intake was lower in non-supplemented. Average daily weight gain (ADG) was lower (P < 0.05) for T 1 compared to all supplemented treatments except T 5. Hot carcass weight and rib-eye muscle area also followed the same trend like that of ADG. Compared with feeding hay alone, supplementing with CSM or a mixture of CSM and Pjp appeared to be a better feeding strategy, biologically, for yearling Afar rams.

There is limited representative information on ART drug adherence and its associated factors from Southern Ethiopia. We aimed at estimating the level of adherence to ART among people living with HIV and factors associated with it in 20 randomly selected ART clinics of Southern Ethiopia.Methods: In this cross-sectional study, we interviewed consecutive HIV patients on first-line antiretroviral regimen attending the clinics in June 2014 using a pretested and structured questionnaire. For measuring adherence, we used 4-day recall method based on “The AIDS Clinical Trial Group adherence assessment tool”. Patients were classified as “Incomplete adherence” if they missed any of the doses in the last 4 days. Data were singly entered using EpiData and descriptive analysis, and unadjusted odds ratios were calculated using EpiDataStat software. Multivariate logistic regression analysis was performed using Stata v12.0.Results: Of 974 patients interviewed, 539 (56% were females, and mean age was 35 years. The proportion of patients with incomplete adherence was 13% (95% confidence interval: 11%–15

    Objective: To examine the prevalence of cutaneous disorders in children under 5 years old who attended a rural hospital in Southern Ethiopia. Methods: A prospective cross-sectional study was conducted from January 26 to February 20, 2015 in children under 5 years old who attended Gambo Rural Hospital in West Arsi of the Oromia Region, Ethiopia. Results: A total of 324 children were included (59.6%male) whose median age was 16.4 months. In total, 147 children [45.4%; 95% confidence interval (CI): 40.0%–50.8%] under 5 years had a skin problem, of which 101 (68.7%) consulted for that reason. The other 46 (31.3%) consulted for a general health problem and the dermatological condition was a secondary finding during the physical exploration. In 93 children (28.7%;95%CI:20%–33.8%), it was the main disease, and in 54 children (16.5%;95%CI:13.0%–21.1%) it was concomitant with other diseases. The most common dermatological disease was scabies (n=44, 13.6%;95%CI:10.3%–17.7%). Impetigo was diagnosed in 32 children (9.9%;95%CI:7.1%–13.3%), of which 23 (71.9%) had complicated impetigo. Nineteen children (5.9%;95%CI:3.8%–9.0%) had eczema, 10 (3.1%) had eczema associated to other conditions. The following most frequent skin problems were tinea (n = 9; 2.8%), infected wound and ulcer (n=7;2.2%), and burns (n=6;1.9%). Conclusions: Skin problems, mainly scabies, impetigo, and eczema were common in young children attended at a rural hospital in Southern Ethiopia. Children under 5 years should be examined thoroughly to rule out skin diseases, especially scabies.

    Full Text Available Abstract Background Voluntary HIV counselling and testing (VCT is one of the key strategies in the HIV/AIDS prevention and control programmes in Ethiopia. However, utilization of this service among adults is very low. The aim of the present study was to investigate factors associated with VCT utilization among adult men since men are less likely than women to be offered and accept routine HIV testing. Methods The study utilized data from the Ethiopian Demographic Health Survey (EDHS 2005, which is a cross-sectional survey conducted on a nationally representative sample. Using cluster sampling, 6,778 men aged 15–59 years were selected from all the eleven administrative regions in Ethiopia. Logistic regression was used to analyze potential factors associated with VCT utilization. Results Overall, 21.9% of urban men and 2.6% of rural men had ever tested for HIV through VCT and most of them had learned their HIV test result. Having no stigmatizing attitudes toward people living with HIV/AIDS was found to be strongly and positively associated with VCT utilization in both urban and rural strata. In rural areas HIV test rates were higher among younger men (aged ≤44 years and those of higher socio-economic position (SEP. Among urban men, risky sexual behaviour was positively associated with VCT utilization whereas being Muslim was found to be inversely associated with utilization of VCT. Area of residence as well as SEP strongly affected men’s level of stigmatizing attitudes toward people living with HIV/AIDS. Conclusions VCT utilization among men in Ethiopia was low and affected by HIV/AIDS-related stigma and residence. In order to increase VCT acceptability, HIV/AIDS prevention and control programs in the country should focus on reducing HIV/AIDS-related stigma. Targeting rural men with low SEP should be given first priority when designing, expanding, and implementing VCT services in the country.

    Full Text Available An up-to-date and reliable map of podoconiosis is needed to design geographically targeted and cost-effective intervention in Ethiopia. Identifying the ecological correlates of the distribution of podoconiosis is the first step for distribution and risk maps. The objective of this study was to investigate the spatial distribution and ecological correlates of podoconiosis using historical and contemporary survey data.Data on the observed prevalence of podoconiosis were abstracted from published and unpublished literature into a standardized database, according to strict inclusion and exclusion criteria. In total, 10 studies conducted between 1969 and 2012 were included, and data were available for 401,674 individuals older than 15 years of age from 229 locations. A range of high resolution environmental factors were investigated to determine their association with podoconiosis prevalence, using logistic regression.The prevalence of podoconiosis in Ethiopia was estimated at 3.4% (95% CI 3.3%-3.4% with marked regional variation. We identified significant associations between mean annual Land Surface Temperature (LST, mean annual precipitation, topography of the land and fine soil texture and high prevalence of podoconiosis. The derived maps indicate both widespread occurrence of podoconiosis and a marked variability in prevalence of podoconiosis, with prevalence typically highest at altitudes >1500 m above sea level (masl, with >1500 mm annual rainfall and mean annual LST of 19-21°C. No (or very little podoconiosis occurred at altitudes 24°C.Podoconiosis remains a public health problem in Ethiopia over considerable areas of the country, but exhibits marked geographical variation associated in part with key environmental factors. This is work in progress and the results presented here will be refined in future work.

    Mitochondrial DNA (mtDNA) haplotypes were determined using restriction fragment length polymorphism (RFLP) for P. infestans sampled from 513 foliar lesions of late blight found on potato and tomato in different regions of Ethiopia. Among the four reported mitochondrial haplotypes of Phytophthora infestans, Ia, Ib and IIb were detected in 93 % of the samples analyzed but the vast majority of these were Ia. The remaining 7 % represented a previously unreported haplotype. DNA sequencing of this new haplotype also confirmed a single base nucleotide substitution that resulted in loss of EcoRI restriction site and gain of two additional MspI sites in cox1 and atp1 genes, respectively. There were 28 polymorphic sites among all nucleotide sequences including five reference isolates. Sites with alignment gaps were observed in P4 with one nucleotide deletion in 11 Ethiopian isolates. None of the reference sequence produced frame-shifts, with the exception of the 3-nucleotide deletion in the P4 region by Phytophthora andina, a feature that can be used to distinguish the new Ethiopian isolates from P. andina. While a distinguishing molecular data presented here clearly separated them from P. infestans, 7 % of the isolates that share this feature formed an important component of the late blight pathogen causing disease on Solanum tuberosum in Ethiopia. Thus, these Ethiopian isolates could represent a novel Phytophthora species reported for the first time here.

    As a country whose economy is heavily dependent on low-productivity rainfed agriculture, rainfall trends are often cited as one of the more important factors in explaining various socio-economic problems such as food insecurity. Therefore, in order to help policymakers and developers make more informed decisions, this study investigated the temporal dynamics of rainfall and its spatial distribution within Ethiopia. Changes in rainfall were examined using data from 134 stations in 13 watersheds between 1960 and 2002. The variability and trends in seasonal and annual rainfall were analysed at the watershed scale with data (1) from all available years, and (2) excluding years that lacked observations from at least 25% of the gauges. Similar anlyses were also performed at the gauge, regional, and national levels. By regressing annual watershed rainfall on time, results from the one-sample t-test show no significant changes in rainfall for any of the watersheds examined. However, in our regressions of seasonal rainfall averages against time, we found a significant decline in June to September rainfall (i.e. Kiremt) for the Baro-Akobo, Omo-Ghibe, Rift Valley, and Southern Blue Nile watersheds located in the southwestern and central parts of Ethiopia. While the gauge level analysis showed that certain gauge stations experienced recent changes in rainfall, these trends are not necessarily reflected at the watershed or regional levels.

    We conducted a cluster randomized trial of the effects of the integrated community case management of childhood illness (iCCM) strategy on careseeking for and coverage of correct treatment of suspected pneumonia, diarrhea, and malaria, and mortality among children aged 2-59 months in 31 districts of the Oromia region of Ethiopia. We conducted baseline and endline coverage and mortality surveys approximately 2 years apart, and assessed program strength after about 1 year of implementation. Results showed strong iCCM implementation, with iCCM-trained workers providing generally good quality of care. However, few sick children were taken to iCCM providers (average 16 per month). Difference in differences analyses revealed that careseeking for childhood illness was low and similar in both study arms at baseline and endline, and increased only marginally in intervention (22.9-25.7%) and comparison (23.3-29.3%) areas over the study period (P = 0.77). Mortality declined at similar rates in both study arms. Ethiopia's iCCM program did not generate levels of demand and utilization sufficient to achieve significant increases in intervention coverage and a resulting acceleration in reductions in child mortality. This evaluation has allowed Ethiopia to strengthen its strategic approaches to increasing population demand and use of iCCM services.

    Background An increasing number of malaria-endemic African countries are rapidly scaling up malaria prevention and treatment. To have an initial estimate of the impact of these efforts, time trends in health facility records were evaluated in selected districts in Ethiopia and Rwanda, where long-lasting insecticidal nets (LLIN) and artemisinin-based combination therapy (ACT) had been distributed nationwide by 2007. Methods In Ethiopia, a stratified convenience sample covered four major regions where (moderately) endemic malaria occurs. In Rwanda, two districts were sampled in all five provinces, with one rural health centre and one rural hospital selected in each district. The main impact indicator was percentage change in number of in-patient malaria cases and deaths in children < 5 years old prior to (2001–2005/6) and after (2007) nationwide implementation of LLIN and ACT. Results In-patient malaria cases and deaths in children < 5 years old in Rwanda fell by 55% and 67%, respectively, and in Ethiopia by 73% and 62%. Over this same time period, non-malaria cases and deaths generally remained stable or increased. Conclusion Initial evidence indicated that the combination of mass distribution of LLIN to all children < 5 years or all households and nationwide distribution of ACT in the public sector was associated with substantial declines of in-patient malaria cases and deaths in Rwanda and Ethiopia. Clinic-based data was a useful tool for local monitoring of the impact of malaria programmes. PMID:19144183

It can potentially affect the provision of health services; however, this important attribute of the workplace climate in public hospitals is not usually given serious attention to the desired level. For this reason, the authors of this study have assessed the level of motivation of health professionals and associated factors in public hospitals of West Amhara, Northwest Ethiopia.  Methods: A facility based cross-sectional study was conducted in eight public hospitals of West Amhara from June 1 to July 30, 2013. A total of 304 health professionals were included in this study. The collected data were analyzed using SPSS software version 20. The reliability of the instrument was assessed through Cronbach’s α. Factor scores were generated for the items found to represent the scales (eigenvalue greater than one in varimax rotation used in the measurement of the variables. The scores were further analyzed using one-way analysis of variance, t-tests, Pearson’s correlation, and hierarchical multiple linear regression analyses.

    Full Text Available Abstract Background Iodine deficiency is severe public health problem in Ethiopia. Although urinary iodine excretion level (UIE is a better indicator for IDD the goitre rate is commonly used to mark the public health significance. The range of ill effect of IDD is however beyond goitre in Ethiopia. In this study the prevalence of goitre and its association with reproductive failure, and the knowledge of women on Iodine Deficiency were investigated. Methods A cross-section community based study was conducted during February to May 2005 in 10998 women in child bearing age of 15 to 49 years. To assess the state of iodine deficiency in Ethiopia, a multistage "Proportional to Population Size" (PPS sampling methods was used, and WHO/UNICEF/ICCIDD recommended method for goitre classification. Results Total goitre prevalence (weighted was 35.8% (95% CI 34.5–37.1, 24.3% palpable and 11.5% visible goitre. This demonstrates that more than 6 million women were affected by goitre. Goitre prevalence in four regional states namely Southern Nation Nationalities and People (SNNP, Oromia, Bebshandul-Gumuz and Tigray was greater than 30%, an indication of severe iodine deficiency. In the rest of the regions except Gambella, the IDD situation was mild to moderate. According to WHO/UNICEF/ICCIDD this is a lucid indication that IDD is a major public health problem in Ethiopia. Women with goitre experience more pregnancy failure (X2 = 16.5, p 2 = 67.52; p Conclusion Ethiopia is at risk of iodine deficiency disorders. The findings presented in this report emphasis on a sustainable iodine intervention program targeted at population particularly reproductive age women. Nutrition education along with Universal Salt Iodization program and iodized oil capsule distribution in some peripheries where iodine deficiency is severe is urgently required.

    Long-term human impacts are considered to be the prime cause of unsustainable forest exploitation in Ethiopia. Yet there exist well-established systems and a wealth of local experience in maintaining and managing forests. This study explores the trends and driving forces of deforestation plus traditional practices regarding sustainable forest use and management in the Chencha and Arbaminch areas, Southern Ethiopia. Satellite image analysis (images from 1972, 1984 and 2006) combined with field surveys were used to detect and map changes in forest cover. Household interviews and group discussions with experienced and knowledgeable persons were also employed. The results show a 23 % decline in forest cover between 1972 and 2006 with the most significant change from 1986 to 2006. Change was greatest in the lowlands and remarkable episodic forest changes also occurred, suggesting nonlinear spatial and temporal forest cover dynamics. According to farmers, the main driver of deforestation is agricultural land expansion in response to local population increases and a decline in agricultural production. Growing local and regional fuel wood demand is another chief cause. Despite these issues, remarkable relicts of natural forests remain and trees on farmland, around homesteads and on fields in every village are basic elements of farm activities and social systems. This demonstrates the effect of cumulative traditional knowledge and long-term local experience with forest management and preservation. Therefore, these practices should be promoted and advanced through the integration of local knowledge and forest management practices in the design and implementation of sustainable environmental planning and management.

    Full Text Available Background. Zinc deficiency occurs in infants when its demand exceeds its supply. It presents with cutaneous signs which, in severe cases, are associated with diarrhea, alopecia, and irritability. Genetic and acquired forms of zinc deficiency have been reported and often overlap clinical features. Malnutrition, prematurity, malabsorption syndromes, and burns may cause an increased demand for zinc. Methods. Cases of acquired transient infantile zinc deficiency (TIZD observed during a period of 3 years at Ayder Referral Hospital of Mekelle, Northern Ethiopia, are reported here. Since no sophisticated tests were available at our center, the diagnosis was based on the clinical signs and prompt response to oral zinc supplementation. Results. We observed 18 cases of TIZD at our center. All patients were full-term and breastfeeding infants with no relevant associated diseases. Conclusions. In this region, a high incidence of this condition is observed. We could not rule out whether heterozygosity for the genetic mutation was present or that the disease was caused by a nutritional deficiency in the mothers or more probably because both the factors coexisted together. However, further studies are necessary to better understand the causes of the increased incidence of this disease in Northern Ethiopia.

    Full Text Available Bamboo is an abundant resource in Ethiopia and has a great potential for commercialization, which can drive rural development. In view of these realities, this study analyzed the state and determinants of small-scale bamboo commercialization in Ethiopia. Data were collected from three major bamboo-growing districts (Awi, Sidama, and Sheka and four urban centers (Masha, Hawassa, Bahir Dar, and Addis Ababa via semi-structured interviews, group discussions, and questionnaire surveys with key actors along the value chain. Results revealed distinctive differences in proportion of cash income, value chain structure, and management engagement among the districts. Percentages of cash income were 60.15, 42.60, and 9.48 at Awi, Sidam, and Sheka, respectively. Differences were statistically significant between Sheka and both other districts (p = 0.05, but not between Awi and Sidama. The value chain structure showed that compared with Sheka, Awi and Sidama have a relatively large number of actors involved. The major factors explaining commercialization differences among regions were distance to market and presence of alternative forest products. Within Sheka, households with larger family size, higher education attainment, and access to training reportedly engaged more in commercial extraction. Therefore, we conclude that development of infrastructure for linking resource and consumer centers and expansion of extension education among producers may enhance the commercial engagement of producers and improve the accessibility of bamboo resources for commercial production.

    Hepatitis B virus (HBV) is genetically highly divergent and classified in ten genotypes and forty subgenotypes in distinct ethno-geographic populations worldwide. Ethiopia is a country with high HBV prevalence; however, little is known about the genetic variability of HBV strains that circulate. Here, we characterize the complete genome of 29 HBV strains originating from five Ethiopian regions, by 454 deep sequencing and Sanger sequencing. Phylogenetically, ten strains were classified as genotype A1 and nineteen as genotype D. Fifteen genotype D strains, provisionally named subgenotype D10, showed a novel distinct cluster supported by high bootstrap value and >4% nucleotide divergence from other known subgenotypes. In addition, the novel D10 strains harboured nine unique amino acid signatures in the surface, polymerase and X genes. Seventy-two per cent of the genotype D strains had the precore premature stop codon G1896A. In addition, 63% genotype A and 33% genotype D strains had the basal core promoter mutations, A1762T/G1764A. Furthermore, four pre-S deletion variants and two recombinants were identified in this study. In conclusion, we identified a novel HBV subgenotype D10 circulating in Ethiopia, underlining the high genetic variability of HBV strains in Africa.

    Melophagus ovinus (sheep ked) is one of the most common ectoparasites that contributes to enormous economic losses in the productivity of sheep in many countries. The present study was conducted from January 2012 to July 2013 on M. ovinus collected from sheep at three sites in Ethiopia. Of the sheep studied, 65.7% (88/134) were infested with M. ovinus. The prevalence of M. ovinus was 76% (76/100), 47% (8/17) and 23.5% (4/17) at the Kimbibit, Chacha and Shano sites, respectively. An overall number of 229 M. ovinus specimens (138 females, 86 males and five pupae) and 554 M. ovinus specimens (272 females, 282 males) were collected from young and adult sheep, respectively. Bartonella DNA was detected in 89% (694/783) of M. ovinus using a quantitative Bartonella genus-specific PCR assay targeting the 16S/23S rRNA intergenic spacer region. The sequencing of the PCR products of fragments of the gltA and rpoB genes showed 99.6-100% and 100% homology, respectively, with B. melophagi. Statistically significant variation was not noted in the overall prevalence of Bartonella DNA between female and male M. ovinus. All of the sheep infested with M. ovinus 100% (88/88) harbored at least one M. ovinus specimen that contained Bartonella DNA. This study highlights that B. melophagi in M. ovinus from sheep in highlands in Ethiopia possibly has certain zoonotic importance.

    Full Text Available Water is the primary source of life for mankind and one of the most basic necessities for rural development. Most of the rural areas of Ethiopia do not have access to potable water. Is some regions of the country access potable water is available through use of manual pumping and Diesel engine. In this research, wind water pump is designed to supply drinking water for three selected rural locations in Ethiopia. The design results show that a 5.7 m diameter windmill is required for pumping water from borehole through a total head of 75, 66 and 44 m for Siyadberand Wayu, Adami Tulu and East Enderta to meet the daily water demand of 10, 12 and 15 m3, respectively. The simulation for performance of the selected wind pump is conducted using MATLAB software and the result showed that monthly water discharge is proportional to the monthly average wind speed at the peak monthly discharge of 685 m3 in June, 888 m3 in May and 1203 m3 in March for Siyadberand Wayu, Adami Tulu and East Enderta sites, respectively. An economic comparison is conducted, using life cycle cost analysis, for wind mill and Diesel water pumping systems and the results show that windmill water pumping systems are more feasible than Diesel based systems.

  11. Secular spring rainfall variability at local scale over Ethiopia: trend and associated dynamics

    Spring rainfall secular variability is studied using observations, reanalysis, and model simulations. The joint coherent spatio-temporal secular variability of gridded monthly gauge rainfall over Ethiopia, ERA-Interim atmospheric variables and sea surface temperature (SST) from Hadley Centre Sea Ice and SST (HadISST) data set is extracted using multi-taper method singular value decomposition (MTM-SVD). The contemporaneous associations are further examined using partial Granger causality to determine presence of causal linkage between any of the climate variables. This analysis reveals that only the northwestern Indian Ocean secular SST anomaly has direct causal links with spring rainfall over Ethiopia and mean sea level pressure (MSLP) over Africa inspite of the strong secular covariance of spring rainfall, SST in parts of subtropical Pacific, Atlantic, Indian Ocean and MSLP. High secular rainfall variance and statistically significant linear trend show consistently that there is a massive decline in spring rain over southern Ethiopia. This happened concurrently with significant buildup of MSLP over East Africa, northeastern Africa including parts of the Arabian Peninsula, some parts of central Africa and SST warming over all ocean basins with the exception of the ENSO regions. The east-west pressure gradient in response to the Indian Ocean warming led to secular southeasterly winds over the Arabian Sea, easterly over central Africa and equatorial Atlantic. These flows weakened climatological northeasterly flow over the Arabian Sea and southwesterly flow over equatorial Atlantic and Congo basins which supply moisture into the eastern Africa regions in spring. The secular divergent flow at low level is concurrent with upper level convergence due to the easterly secular anomalous flow. The mechanisms through which the northwestern Indian Ocean secular SST anomaly modulates rainfall are further explored in the context of East Africa using a simplified atmospheric

However, with the recent rapid expansion in medical education training, it is expected that the country can make progress in physician workforce supply. Therefore, the aim of this study was to examine the distribution of physician workforce in Ethiopia and assess the role of retention mechanisms in the reduction of physician migration from the public health sector of Ethiopia. Methods: This organizational survey examined physician workforce data from 119 hospitals from 5 regions (Amhara, Oromia, Southern Nations Nationalities and Peoples Region [SNNPR], Tigray, and Harari and 2 city administrations (Addis Ababa and Dire Dawa City. Training opportunity, distribution, and turnover between September 2009 and July 2015 were analyzed descriptively. Poisson regression model was used to find the association of different covariates with physician turnover. Results: There were 2,300 medical doctors in 5 regions and 2 city administrations in ~6 years of observations. Of these, 553 (24.04% medical doctors moved out of their duty stations and the remaining 1,747 (75.96% were working actively. Of the actively working, the majority of the medical doctors, 1,407 (80.5%, were males, in which 889 (50.9% were born after the year 1985, 997 (57% had work experience of <3 years, and most, 1,471 (84.2%, were general practitioners. Within the observation period, physician turnover among specialists ranged from 21.4% in Dire Dawa to 43.3% in Amhara region. The capital, Addis Ababa, was the place of destination for 32 (82% of the physicians who moved out to

    Full Text Available Determining the optimal capital structure is one of the most fundamental policy decisions faced by financial managers. Since optimal debt ratio influences firm’s value, different firms determine capital structures at different levels to maximize the value of their firms. Thus, this study examines the relationship between leverage and firm specific (profitability, tangibility, growth, risk, size and liquidity determinants of capital structure decision, and the theories of capital structure that can explain the capital structure of banks in Ethiopia. In order to investigate these issues a mixed method research approach is utilized, by combining documentary analysis and in-depth interviews. More specifically, the study uses twelve years (2000 - 2011 data for eight banks in Ethiopia.   The findings show that profitability, size, tangibility and liquidity of the banks are important determinants of capital structure of banks in Ethiopia. However, growth and risk of banks are found to have no statistically significant impact on the capital structure of banks in Ethiopia. In addition, the results of the analysis indicate that pecking order theory is pertinent theory in Ethiopian banking industry, whereas there are little evidence to support static trade-off theory and the agency cost theory. Therefore, banks should give consideration to profitability, size, liquidity and tangibility when they determine their optimum capital structure.

    Toxoplasmosis caused by the protozoan parasite, Toxoplasma gondii, is a worldwide zoonosis. In this paper published information on toxoplasmosis in humans and other animals in Ethiopia is reviewed. Limited data indicate that the prevalence of T. gondii in humans in Ethiopia is very high, up to 41% of children aged 1-5 years were reported to be seropositive. There is little information on seroprevalence data in pregnant women and no data on congenital toxoplasmosis in children. About 1 million adults in Ethiopia are considered to be infected with HIV with less than one-third likely receive highly active antiviral therapy. Based on a conservative T. gondii seroprevalence of 50%, thousands might die of concurrent opportunistic infections, including toxoplasmosis. However, exact figures are not available, and most serological surveys are not current. Serological surveys indicate up to 79% of goats and sheep have T. gondii antibodies. However, there is no information on losses due to toxoplasmosis in livestock or the presence of viable T. gondii in any host in Ethiopia.

    CLUVA (CLimate change and Urban Vulnerability in Africa; http://www.cluva.eu/) is a 3 years project, funded by the European Commission in 2010. Its objective is to develop context-centered methods to assess vulnerability and increase knowledge on managing climate related risks and to estimate the impacts of climate changes in the next 40 years at urban scale in Africa. The project downscales IPCC climate projections to evaluate threats to selected African test cities; mainly floods, sea-level rise, droughts, heat waves, desertification. It also evaluates and links: social vulnerability; urban green structures and ecosystem services; urban-rural interfaces; vulnerability of urban built environment and lifelines; and related institutional and governance dimensions of adaptation. CLUVA combines assessment approaches to investigate how cities, communities and households can resist and cope with, as well as recover from climate induced hazards. This multi-scale and multi-disciplinary qualitative, quantitative and probabilistic approach of CLUVA is currently being applied to selected African test cities (Addis Ababa - Ethiopia; Dar es Salaam - Tanzania; Douala - Cameroun; Ouagadougou - Burkina Faso; St. Louis - Senegal). In particular, the poster will report on the progresses of the Addis Ababa case study. Addis Ababa, the largest city in Ethiopia, is exposed to heat waves, drought, and, more recently, to flash floods. Due to undulating topography, poor waste management and the absence of sustainable storm water management, Addis Ababa is prone to severe flood events during the rainy seasons. Metropolitan Addis Ababa is crossed by several small watercourses. Torrential rains, very common during the rainy season, cause a sudden rise in the flow of these water courses, inundating and damaging the settlements along their banks and affecting the livelihood of the local population. The combination of climate change and development pressures are expected to exacerbate the

This practice results in short- and long-term health consequences on women’s health. Like many other developing countries, FGM is widely practiced in Ethiopia, especially among Somali and Harari ethnic groups. Despite intensive campaigns against FGM in Ethiopia, since 2011, it has been practiced in the aforementioned communities. There is no recent information as to whether these campaigns have an impact on the attitude and practice of the community regarding FGM. This qualitative research was aimed at exploring the attitudes of Somali and Harari people between 18 and 65 years toward FGM.Methods: A purposive sampling technique was used to recruit 64 (32 in each region participants. Data were collected from October to December 2015 in Somali and Harari Regions.Results: The findings showed that there was a strong support for the continuation of the practice among female discussants in Somali region, whereas male discussants from the same region and the majority of the participants from Harari region had a positive attitude toward the discontinuation of the practice. Marriageability was the major reason for practicing FGM in Somali region, whereas making girls calm, sexually inactive, and faithful for their husbands were mentioned in Harari region. Although young men in both the regions prefer to marry uncircumcised girls, the study showed that there are some differences in the attitude toward the FGM practice between the people in the two regions.Conclusion: The findings

    Full Text Available Cystic echinococcosis is a cestode infection caused by the larval stage of Echinocococcus granulosus. It is an important zonoses, as humans get infected by ingesting eggs passed in the feces of dogs, and important cause of economic loss mainly due to organ condemnation and reducing the quality of meat, milk, and wool production. Hydatidosis is prevalent in cattle and small ruminant population of Ethiopia in a range of 3.1% to 72.44%. The prevalence rate reaches up to 30.8% in camels and 25% in dogs. Very few retrospective and case reports of cystic human hydatidosis also indicated the relevance of the disease in the human population of the country. Besides to the scarcity of reports the slow growing nature of disease development may result in underestimation of the situation. Economic losses in a range of 3201 to 1,167,512 USD have been reported in the country. Diagnosis of the larvae in the intermediate hosts, especially in humans, is mainly by imaging and immunology techniques. During post mortem examination the cyst can be diagnosed during meat inspection procedures in lungs, liver, heart, spleen, kidneys, muscle bones and other tissues of intermediate hosts. In the definitive host diagnosis can be by demonstration of the parasite from there faces or the small intestine or the detection of specific coproantigens or coproDNA. The role of holistic and systematic interventions approaches involving the public, veterinarians and public health professional for the action to be simultaneous and effectual along with prevalence of hydatidosis are highlighted in the present review.

    Objectives:To isolate and identify the bacterial etiologic agents,including their antibiotic susceptibility pat-tern isolated from patients with discharging ear infections.Methods:Between September 2006 and February 2007,178 patients with discharging ear visiting ENT clinics of St.Paul and Tikur Anbessa University Hospi-tals Addis Ababa,Ethiopia were investigated.Results:Of the patients investigated,52.8% were males and 47.2% were females resulting in an overall male to female ratio of 1.1:1.Ear discharge was the commonest clinical finding followed by hearing problem (91.2%),otalgia (ear pain)(74.7%),fever (17.9%)and itching of external ear (5.1%).S.aureus accounted for 30.2% of the total isolates followed by Proteus ssp. (P.mirabilis,P.vulgaris )(25.4%),and P.aeruginosa (13.4%).Both gram positive and negative bac-teria isolated from ear infections showed low resistance rates to most antimicrobial agents tested.Overall ceftri-axone and ciprofloxacin were the most effective drugs when compared to other drugs tested against the gram-positive and gram-negative bacteria.Conclusion:Otitis media was the most common clinical finding in pa-tients with ear infection.With discharging ear,the gram-negative bacteria were the predominant isolates.The susceptibility pattern of isolates from the study showed that ceftriaxone,ciprofloxacin and gentamicin were the most effective drugs.It is recommended that treatment of ear infections should be based on culture and sensi-tivity at the study sites.Therefore,efforts should be directed towards early diagnosis and treatment of acute ear infection and continued re-evaluation of the resistant patterns of organisms to optimize treatments and reduce complications.

    Ethiopia is central to population genetic studies investigating the out of Africa expansion of modern humans, as shown by Y chromosome and mtDNA studies. To address the level of genetic differentiation within Ethiopia, and its relationship to Sub-Saharan Africa and Eurasia, we studied an 8 kb segment of the X-chromosome from 72 chromosomes from the Amhara, Oromo and Ethiopian Jews, and compared these results with 804 chromosomes from Middle Eastern, African, Asian and European populations, and 22 newly typed Saharawi. Within Ethiopia the two largest ethnic groups, the Amhara and Oromo, were not found to be statistically distinct, based on an exact test of haplotype frequencies. The Ethiopian Jews appear as an admixed population, possibly of Jewish origin, though the data remain equivocal. There is evidence of a close relationship between Ethiopian and Yemenite Jews, likely a result of indirect gene flow. Within an African and Eurasian context, the distribution of alleles of a variable T(n) repeat, and the spread of haplotypes containing Africa-specific alleles, provide evidence of a genetic continuity from Sub-Saharan Africa to the Near East, and furthermore suggest that a bottleneck occurred in Ethiopia associated with an out of Africa expansion. Ethiopian genetic heterogeneity, as evidenced by principal component analysis of haplotype frequencies, most likely resulted from periods of subsequent admixture. While these results are from the analysis of one locus, we feel that in association with data from other marker systems they add a complementary perspective on the history of Ethiopia.

    Background In a large population in Southwest Ethiopia (population 700,000), we carried out a complex set of interventions with the aim of reducing maternal mortality. This study evaluated the effects of several coordinated interventions to help improve effective coverage and reduce maternal deaths. Together with the Ministry of Health in Ethiopia, we designed a project to strengthen the health-care system. A particular emphasis was given to upgrade existing institutions so that they could carry out Basic (BEmOC) and Comprehensive Emergency Obstetric Care (CEmOC). Health institutions were upgraded by training non-clinical physicians and midwives by providing the institutions with essential and basic equipment, and by regular monitoring and supervision by staff competent in emergency obstetric work. Results In this implementation study, the maternal mortality ratio (MMR) was the primary outcome. The study was carried out from 2010 to 2013 in three districts, and we registered 38,312 births. The MMR declined by 64% during the intervention period from 477 to 219 deaths per 100,000 live births (OR 0.46; 95% CI 0.24–0.88). The decline in MMR was higher for the districts with CEmOC, while the mean number of antenatal visits for each woman was 2.6 (Inter Quartile Range 2–4). The percentage of pregnant women who attended four or more antenatal controls increased by 20%, with the number of women who delivered at home declining by 10.5% (Ptraditional birth attendants. Households living near to all-weather roads had lower maternal mortality rates (MMR 220) compared with households without roads (MMR 598; OR 2.72 (95% CI 1.61–4.61)). Conclusions Our results show that it is possible to achieve substantial reductions in maternal mortality rates over a short period of time if the effective coverage of well-known interventions is implemented.

    Breastfeeding is one of the critical issues in Ethiopia because researches show that 24.0% - 27.0% of infant death in Ethiopia is due to poor breastfeeding practices. UNICEF has been reported that a good promotion of breastfeeding practices is a most important strategic plan to reduce child mortality in developed and developing countries. Hence, it is important to identifying the determinate factors of poor breastfeeding practice, especially poor countries like Ethiopia. Poor Breastfeeding is...

    Understanding how natural faults are segmented along their length can provide useful insights into fault growth processes, stress distribution on fault planes, and earthquake dynamics. We use cumulative displacement profiles to analyze the two largest scales of segmentation of ˜900 normal faults in Afar, East Africa. We build upon a prior study by Manighetti et al. (2009) and develop a new signal processing method aimed at recovering the number, position, displacement, and length of both the major (i.e., longest) and the subordinate, secondary segments within the faults. Regardless of their length, age, geographic location, total displacement, and slip rate, 90% of the faults contain two to five major segments, whereas more than 70% of these major segments are divided into two to four secondary segments. In each hierarchical rank of fault segmentation, most segments have a similar proportional length, whereas the number of segments slightly decreases with fault structural maturity. The along-strike segmentation of the Afar faults is thus generic at its two largest scales. We summarize published fault segment data on 42 normal, reverse, and strike-slip faults worldwide, and find a similar number (two to five) of major and secondary segments across the population. We suggest a fault growth scenario that might account for the generic large-scale segmentation of faults. The observation of a generic segmentation suggests that seismogenic fault planes are punctuated with a deterministic number of large stress concentrations, which are likely to control the initiation, arrest and hence extent and magnitude of earthquake ruptures.

    Cutaneous leishmaniasis (CL) is a neglected tropical disease strongly associated with poverty. Treatment is problematic and no vaccine is available. Ethiopia has seen new outbreaks in areas previously not known to be endemic, often with co-infection by the human immunodeficiency virus (HIV) with rates reaching 5.6% of the cases. The present study concerns the development of a risk model based on environmental factors using geographical information systems (GIS), statistical analysis and modelling. Odds ratio (OR) of bivariate and multivariate logistic regression was used to evaluate the relative importance of environmental factors, accepting P ≤ 0.056 as the inclusion level for the model's environmental variables. When estimating risk from the viewpoint of geographical surface, slope, elevation and annual rainfall were found to be good predictors of CL presence based on both probabilistic and weighted overlay approaches. However, when considering Ethiopia as whole, a minor difference was observed between the two methods with the probabilistic technique giving a 22.5% estimate, while that of weighted overlay approach was 19.5%. Calculating the population according to the land surface estimated by the latter method, the total Ethiopian population at risk for CL was estimated at 28,955,035, mainly including people in the highlands of the regional states of Amhara, Oromia, Tigray and the Southern Nations, Nationalities and Peoples' Region, one of the nine ethnic divisions in Ethiopia. Our environmental risk model provided an overall prediction accuracy of 90.4%. The approach proposed here can be replicated for other diseases to facilitate implementation of evidence-based, integrated disease control activities.

    Millions of people throughout the world depend on dam reservoirs for domestic water supply, irrigation, electricity and flood protection. In the last two decades, 54 micro-dam reservoirs have been constructed in Northern Ethiopia to fight the recurrent drought and improve agricultural productivity through irrigation. However, about 60% of these micro-dam reservoirs are suffering from excessive leakage. Comprehensive studies have been carried out on two micro-dams to assess and pinpoint the causes of leakage. Arato and Hashenge micro-dams located in Northern Ethiopia have 20 m and 19 m height, and 2.59 Mm3 and 2.23 Mm3 reservoir capacities respectively. Observational geological description, shallow hand dug test pits, vertical electrical sounding and drilling of geotechnical holes were used to understand the overall geological, engineering geological and geo-hydrological set-up of the area. The different methods applied, such as discontinuity analysis, geophysical surveys, drilling and packer tests, delivered results that were found to be in close agreement and led to the identification of the leakage zone. The geological units found in both sites are limestone-shale-marl intercalation, dolerite and recent soil deposits. The research results revealed that the limestone-shale-marl intercalation unit is heterogeneous and shows alternating sequences. Analysis of the different data shows that the limestone-shale-marl intercalation is a pervious unit (hydraulic conductivity in the range of 10-4-10+2 cm/s) and was found to be responsible for the excessive leakage of the micro-dams. It is hoped that the observations, data and insights gathered from these case studies will enable to plan technically and economically viable anti-leakage measures for these schemes and help for future new site selection and design activities in the region and other regions with a similar geological environment.

    2015-01-01

    Full Text Available Anemia is a major public health problem worldwide. In Ethiopia, a nationally representative and consistent evidence is lacking on the prevalence and determinants during pregnancy. We conducted an in-depth analysis of demographic and health survey for the year 2011 which is a representative data collected from all regions in Ethiopia. Considering maternal anemia as an outcome variable, predicting variables from sociodemographic, household, and reproductive/obstetric characteristics were identified for analyses. Logistic regression model was applied to identify predictors at P<0.05. The prevalence of anemia among pregnant women was 23%. Maternal age, region, pregnancy trimester, number of under five children, previous history of abortion (termination of pregnancy, breastfeeding practices, and number of antenatal care visits were key independent predictors of anemia during pregnancy. In conclusion, the level of anemia during pregnancy is a moderate public health problem in Ethiopia. Yet, special preventive measures should be undertaken for pregnant women who are older in age and having too many under five children and previous history of abortion. Further evidence is expected to be generated concerning why pregnant mothers from the eastern part of the country and those with better access to radio disproportionately develop anemia more than their counterparts.

    adapted to coastal plain wetland environments with the return of humid conditions in the Middle to early Late Triassic. The present data constitute the first paleontologically substantiated record for the existence of Permian strata in the Blue Nile Basin. The new results allow for the first time a reliable biostratigraphic subdivision of the central Ethiopia Karoo and its correlation with coeval strata of adjacent regions in Gondwana. From a phytogeographic point of view, the overall microfloral evidence is in support of the position of central Ethiopia occupying the northern part of the southern Gondwana palynofloral province. In view of palaeoecological and paleoclimatic conditions, the microfloral change from the base to the top of the studied section may indicate a response to shifting climatic belts from warm- and cool-temparate climate in the earliest Permian to progressively drier seasonal conditions at successively higher palaeolatitudes during the Late Permian to Middle Triassic.

    2014-06-01

    An estimated 95% of the population of Ethiopia uses traditional biomass fuels, such as wood, dung, charcoal, or crop residues, to meet household energy needs. As a result of the harmful smoke emitted from the combustion of biomass fuels, indoor air pollution is responsible for more than 50,000 deaths annually and causes nearly 5% of the burden of disease in Ethiopia. Very limited research on indoor air pollution and its health impacts exists in Ethiopia. This study was, therefore, undertaken to assess the magnitude of indoor air pollution from household fuel use in Addis Ababa, the capital city of Ethiopia. During January and February, 2012, the concentration of fine particulate matter (PM2.5) in 59 households was measured using the University of California at Berkeley Particle Monitor (UCB PM). The raw data was analysed using Statistical Package of Social Science (SPSS version 20.0) software to determine variance between groups and descriptive statistics. The geometric mean of 24-h indoor PM2.5 concentration is approximately 818 μg m-3 (Standard deviation (SD = 3.61)). The highest 24-h geometric mean of PM2.5 concentration observed were 1134 μg m-3 (SD = 3.36), 637 μg m-3 (SD = 4.44), and 335 μg m-3 (SD = 2.51), respectively, in households using predominantly solid fuel, kerosene, and clean fuel. Although 24-h mean PM2.5 concentration between fuel types differed statistically (P 0.05). The study revealed indoor air pollution is a major environmental and health hazard from home using biomass fuel in Addis Ababa. The use of clean fuels and efficient cooking stoves is recommended.

    Piroplasmosis caused by different tick-borne hemoprotozoan parasites of the genera Theileria and Babesia is among the most economically important infections of domestic ruminants in sub-Saharan Africa. A survey for piroplasm infection was conducted in three locations in Northern Ethiopia. Of 525 domestic ruminants surveyed, 80% of the cattle, 94% of the sheep and 2% of the goats were positive for different Theileria spp. based on PCR of blood followed by DNA sequencing. Sheep had a significantly higher rate of infection compared with cattle (PTheileria were detected in cattle: T. velifera, T. mutans, T. orientalis complex and T. annulata with infection rates of 66, 8, 4, and 2%, respectively. This is the first report of T. annulata, the cause of Tropical Theileriosis in Ethiopia. Of the two Theileria spp. detected in small ruminants, T. ovis was highly prevalent (92%) in sheep and rare in goats (1.5%) whereas T. seperata was infrequent in sheep (2%) and rare in goats (0.4%). None of the animals were positive for Babesia spp.; however, Sarcocystis capracanis and S. tenella were detected in one goat and a sheep, respectively. The widespread distribution of Theileria spp. among cattle in northern Ethiopia including the virulent T. annulata and more mildly pathogenic T. mutans and T. orientalis, and the high infection rate in sheep with the usually sub-clinical T. ovis indicate extensive exposure to ticks and transmission of piroplasms with an important economic impact.

    Cutaneous leishmaniasis (CL) is endemic in Ethiopia. An unusual clinical form of this disease is leishmaniasis recidivans (LR), a prolonged, relapsing form of cutaneous leishmaniasis resembling tuberculosis of the skin that may persist for many years with a chronic and relapsing course. This rare variant has been shown to be caused by Leishmania tropica species in the Old World and by Leishmania braziliensis, Leishmania amazonensis, Leishmania panamensis, and Leishmania guyanensis in the New World, as reported in various studies. To our knowledge, there are no reports from Ethiopia, and mucocutaneous involvement of LR has not been described to date. This was a retrospective analysis of the patients seen at the Italian Dermatological Center in Mekelle on the Tigrean highlands over a three-year period (2008-2011). Seven patients with typical clinical features of LR were seen. Two of them presented with signs of mucosal involvement. To date, Leishmania aethiopica is shown to be the only species causing CL that is endemic in the Ethiopian highlands. Therefore, it had to be assumed that the lesions in these patients were caused by this species. The aims of this communication are to report, for the first time, the presence of LR, most likely due to Leishmania aethiopica, in Ethiopia, and to report mucosal involvement in this rare clinical form of CL.

    This paper examines the net effect of women's autonomy on their health seeking behavior in Ethiopia. We hypothesize that women with higher autonomy are more likely to seek health care during pregnancy and delivery than those with lower autonomy. The paper also examines whether the autonomy-health utilization relationship is influenced by individual (education, work status, religion) and, household (wealth and rural-urban residence) level factors, all of which are important for both autonomy and health-care utilization. Results indicate that women's autonomy remains significant even after adjusting for other individual and household variables. Besides autonomy, our results highlight other individual and household level influences on the health seeking behaviors of women in Ethiopia. Results also demonstrate the need to look beyond individual level factors when examining the health seeking behaviors of women in Ethiopia. The statistical significance of some individual-level measures, such as education means it cannot be used as proxy for women's autonomy. This calls for policy makers not only to empower women, but also provide them with better formal education.

Both in low- and high-income countries, mainly from outpatient clinics and tuberculosis settings, indicates that the direct offer of HIV testing by health providers can result in significant improvements in test uptake. In Ethiopia, there were limited numbers of studies conducted regarding PITC in outpatient clinics. Therefore, in this study, we have assessed the factors affecting the acceptance of PITC among outpatient clients in selected health facilities in Harar, Harari Region State, Ethiopia. Materials and methods: Institutional-based, cross-sectional quantitative and qualitative studies were conducted from February 12–30, 2011 in selected health facilities in Harar town, Harari Region State, Ethiopia. The study participants were recruited from the selected health facilities of Harar using a systematic random sampling technique. The collected data were double entered into a data entry file using Epi Info version 3.5.1. The data were transferred to SPSS software version 16 and analyzed according to the different variables. Results: A total of 362 (70.6% clients accepted PITC, and only 39.4% of clients had heard of PITC in the outpatient department service. Age, occupation, marital status, anyone who wanted to check their HIV status, and the importance of PITC were the variables that showed significant associations with the acceptance of PITC upon bivariate and multivariate analyses. The main reasons given for not accepting the tests were self-trust, not being at risk for HIV, not being ready, needing to consult their

    Full Text Available Abstract Background Ethiopia is one of the most densely populated countries in Africa with an estimated population of 77.1 million in mid-2007. Uncontrolled fertility has adversely influenced the socio-economic, demographic and environmental situations of the country. It is one of the largest and poorest countries that, even in the midst of crisis, has maintained high levels of fertility. This study was aimed at investigating the most important factors influencing fertility behavior in Northwest Ethiopia. Methods A comparative cross-sectional study which included 2424 women aged 25 years and above was undertaken in the Amhara region of Northwest Ethiopia. The study subjects were grouped into high fertile and low fertile categories. There were 1011 and 1413 women in the high and low fertile groups, respectively. A multi-stage cluster sampling stratified by place of residence was employed to select the required study subjects. Both bivariate and multivariate logistic regression techniques were used to analyze the data. Results Among the 25 variables considered in this study, only 9 of them were found significantly and independently associated with the level of fertility. Women with at least secondary education were at a lower risk of high fertility with OR = 0.37 (95% CI: 0.21 to 0.64 compared to those with no formal education. However, women with primary education did not show any significant difference when compared with the same baseline group. Age at first marriage was inversely associated with the number of children ever born alive. Place of residence, household expenditure, number of children who have died, attitude towards using contraceptives, women's knowledge on the safe period, and current marital status were the other variables that showed significant associations with the level of fertility. Conclusion Female education beyond the primary level, reduced infant and child mortality, delayed marriage and correct knowledge on the safe

    Full Text Available Abstract Background Eastern Ethiopia hosts a substantial number of refugees originated from Somalia. Female genital mutilation (FGM is a common practice in the area, despite the campaigns to eliminate it. Methods A cross-sectional study was conducted among 492 respondents sampled from three refugee camps in Somali Regional State, Eastern Ethiopia, to determine the prevalence and associated factors of FGM. Data were collected using pre-tested structured questionnaires. Results Although the intention of the parents to circumcise their daughters was high (84%, 42.4% of 288 ≤12 girls were reported being undergone FGM. The prevalence increased with age, and about 52% and 95% were circumcised at the age of 7–8 and 11–12 years, respectively. Almost all operations were performed by traditional circumcisers (81% and birth attendants (18%. Clitoral cutting (64% and narrowing of the vaginal opening through stitching (36% were the two common forms of FGM reported by the respondents. Participation of the parents in anti-FGM interventions is statistically associated with lower practice and intention of the procedures. Conclusion FGM is widely practised among the Somali refugee community in Eastern Ethiopia, and there was a considerable support for the continuation of the practice particularly among women. The findings indicate a reported shift of FGM from its severe form to milder clitoral cutting. More men than women positively viewed anti-FGM interventions, and fewer men than women had the intention to let their daughters undergo FGM, indicating the need to involve men in anti-FGM activities.

    Full Text Available Abstract Background Although breastfeeding is universal in Ethiopia, ranges of regional differences in timely initiation of breastfeeding have been documented. Initiation of breastfeeding is highly bound to cultural factors that may either enhance or inhibit the optimal practices. The government of Ethiopia developed National Infant and Young Child Feeding Guideline in 2004 and behavior change communications on breast feeding have been going on since then. However, there is a little information on the practice of timely initiation of breast feeding and factors that predict these practices after the implementation of the national guideline. The objective of this study is to determine the prevalence and determinant factors of timely initiation of breastfeeding among mothers in Bale Goba District, South East Ethiopia. Methods A community based cross sectional study was carried out from February to March 2010 using both quantitative and qualitative methods of data collection. A total of 608 mother infant pairs were selected using simple random sampling method and key informants for the in-depth interview were selected conveniently. Descriptive statistics, bivariate analysis and multivariable logistic regression analyses were employed to identify factors associated with timely initiation of breast feeding. Results The prevalence of timely initiation of breastfeeding was 52.4%. Bivariate analysis showed that attendance of formal education, being urban resident, institutional delivery and postnatal counseling on breast feeding were significantly associated with timely initiation of breastfeeding (P Conclusions The practice of timely initiation of breast feeding is low as nearly half the mothers did not start breastfeeding with one hour after delivery. The results suggest that breast feeding behavior change communication especially during the post natal period is critical in promoting optimal practice in the initiation of breast feeding.

    A total of six soil samples were collected around rhizosphere of citrus plants during 2010 from Melkassa Agricultural Research Center experimental station, Ethiopia. From these samples two most important ecto-plant parasitic nematodes of the genus Xiphinema were found and analysed. The genus Xiphinema is a large group of the phylum nematoda which constitutes more than 260 species. They are polyphagous root- ectoparasites of many crop plants and some species of this genus cause damage by direct feeding on root tips and transmit nepoviruses. The delimitation and discrimination of two species in the genus is presented, described herein as Xiphinemaelongatum and Xiphinemapachtaicum. Morphological and morphometric data were done using light microscopy and results of both species were fit within the previously described nematode species of Xiphinemaelongatum and Xiphinemapachtaicum. 18S rDNA were analysed using Bayesian inference (BI) method to reconstruct phylogenetic relationships of the studied Xiphinema sp. (KP407872Xiphinemaelongatum and KP407873Xiphinemapachtaicum) with other Xiphinema species. The 18S rDNA sequence of Xiphinemapachtaicum was alike to previously described species from the GenBank but Xiphinemaelongatum exhibited very small levels of nucleotides differences (0.4%) which might be possible intra-specific divergence. Though this region of rDNA has less resolution on complex species, its combination with morphological and morphometric analyses, suggests these species as Xiphinemaelongatum and Xiphinemapachtaicum with the GenBank accession number of KP407872 and KP407873, respectively. Short notes, morphological measurements, illustrations, and molecular data are given to these species. These species are reported for the first time from Ethiopia and it provides new geographical information of these organisms.

    Full Text Available Background: Strengthening Laboratory Management Toward Accreditation (SLMTA is a competency-based management training programme. Assessing health professionals’ views of SLMTA provides feedback to inform program planning, implementation and evaluation of SLMTA's training, communication and mentorship components.Objectives: To assess laboratory professionals’ and hospital chief executive officers’ (CEOs perceptions and attitudes toward the SLMTA programme in Ethiopia.Methods: A cross-sectional descriptive survey was conducted in March 2013 using a structured questionnaire to collect qualitative data from 72 laboratory professionals and hospital CEOs from 17 health facilities, representing all regions and two city administrations in Ethiopia. Focus groups were conducted with laboratory professionals and hospital administration to gain insight into the strengths and challenges of the SLMTA programme so as to guide future planning and implementation.Results: Ethiopian laboratory professionals at all levels had a supportive attitude toward the SLMTA programme. They believed that SLMTA substantially improved laboratory services and acted as a catalyst for total healthcare reform and improvement. They also noted that the SLMTA programme achieved marked progress in laboratory supply chain, sample referral, instrument maintenance and data management systems. In contrast, nearly half of the participating hospital CEOs, especially those associated with low-scoring laboratories, were sceptical about the SLMTA programme, believing that the benefits of SLMTA were outweighed by the level of human resources and time commitment required. They also voiced concerns about the cost and sustainability of SLMTA.Conclusion: This study highlights the need for stronger engagement and advocacy with hospital administration and the importance of addressing concerns about the cost and sustainability of the SLMTA programme.

    Full Text Available Neno Nikus Fido, Mamusha Aman, Zewdie Brihnu Department of Health Education and Behavioral Sciences, Jimma University, Jimma, Ethiopia Background: HIV stigma has an important role in the spread of the AIDS epidemic. It profoundly affects the lives of individuals living with HIV/AIDS. Fear of being identified as having HIV may discourage a person from getting tested, accessing medical services, and obtaining medications. Thus, this study was aimed at assessing HIV-related stigma and associated factors among antiretroviral treatment (ART clients in Jimma town, Oromia region, Southwest Ethiopia. Methods: A facility-based cross-sectional study was conducted from March 11 to April 26, 2015, in ART clinics in Jimma town. Consecutively identified sample was obtained from ART clients who voluntarily participated in the survey after signing written consent. A structured interviewer-administered questionnaire was used to collect the data. Multiple linear regressions were conducted to assess the factors associated with various stigma domains. Results: Out of 349 clients requested, 318 (91.1% respondents voluntarily participated in the study; among them, 204 (64.2% respondents were females and the mean age of the respondents was 32.9 years. The mean score (and possible range of experienced HIV stigma was 41.5±12.6 (20.0–86.7, internalized stigma was 50.5±16.4 (20–96.5, and perceived stigma was 56.2±19.2 (20–100. Conclusion: The study revealed that duration of ART use and provider-initiated and forced HIV testing were significantly associated with the three HIV stigma domains. Despite the lower experienced HIV stigma, there were higher internalized and perceived stigmas. Therefore, HIV counseling services should be strengthened for new ART beginners, including pretest counseling. Keywords: HIV/AIDS, Jimma, stigma, ART clients, PLWHA

    Full Text Available Background. In Ethiopia the prevalence of all forms of TB is estimated at 261/100 000 population, leading to an annual mortality rate of 64/100 000 population. The incidence rate of smear-positive TB is 108/100 000 population. Objectives. To assess knowledge, attitudes, and practices regarding TB among pastoralists in Shinille district, Somali region, Ethiopia. Method. A community-based cross-sectional study was conducted among 821 pastoralists aged >18 years and above from February to May, 2011 using self-structured questionnaire. Results. Most (92.8% of the study participants heard about TB, but only 10.1% knew about its causative agent. Weight loss as main symptom, transmittance through respiratory air droplets, and sputum examination for diagnosis were the answers of 34.3%, 29.9%, and 37.9% of pastoralists, respectively. The majority (98.3% of respondents reported that TB could be cured, of which 93.3% believed with modern drugs. About 41.3% of participants mentioned covering the nose and mouth during sneezing and coughing as a preventive measure. The multivariate logistic regression analysis indicated that household income >300 Ethiopian Birr and Somali ethnicity were associated with high TB knowledge. Regarding health seeking behaviour practice only 48.0% of the respondents preferred to visit government hospital and discuss their problems with doctors/health care providers. Conclusion. This study observed familiarity with gaps and low overall knowledge on TB and revealed negative attitudes like discrimination intentions in the studied pastoral community.

    Full Text Available Abstract Background Podoconiosis is a form of non-filarial elephantiasis that affects barefoot individuals in highland tropical areas. The disease presents with bilateral, asymmetric swelling of the legs, usually confined to below the knee. This study aimed to assess podoconiosis patients’ perceptions of prevention, control, causes and familial clustering of the disease, and to document physical, social and economic impairments associated with the disease, with the ultimate aim of enabling development of tailored interventions in this region. Methods This descriptive study is part of the largest cross-sectional community-based household survey yet conducted on podoconiosis. It was completed in November and December, 2011, in Debre Eliyas and Dembecha Woredas of East and West Gojam Zones, northern Ethiopia, and consisted of a house-to-house census by community health workers followed by interviews of identified patients using a structured questionnaire. Results In the 17,553 households surveyed, 1,319 patients were identified. More male as compared to female patients were married (84.6% vs. 53.6%, χ2 = 157.1, p 2 = 102.3, p  Conclusion This study shows that podoconiosis has strong psychosocial, physical and economic impacts on patients in East and West Gojam Zones of northern Ethiopia. Concerns related to familial clustering, poor understanding of the causes and prevention of podoconiosis all add to the physical burden imposed by the disease. Strategies that may ease the impact of podoconiosis include delivery of tailored health education on the causes and prevention of disease, involving patients in intervention activities, and development of alternative income-generating activities for treated patients.

    Full Text Available The interpretation of palaeoclimate records in speleothems depends on the understanding of the modern climate of the region, the geology, the hydrology above the caves, and the within-cave climate. Monitoring within-cave climate variability, geochemistry of speleothem-forming drip waters, and associated surface and groundwater, provides a modern baseline for interpretation of speleothem palaeohydrological and palaeoclimate records. Here, we present results of such monitoring of the Mechara caves in southeastern Ethiopia, conducted between 2004 and 2007. Results show nearly constant within-cave climate (temperature and humidity in all caves, which generally reflects the surface climate. Groundwater and surface water geochemistry is similar across the region (except slight modification by local lithological variations and modern drip water isotope data fall close to regional Meteoric Water Line, but speleothems further from equilibrium. Holocene and modern speleothems from these caves give high-resolution climate records, implying that the Mechara caves provide a suitable setting for the deposition of annually laminated speleothems that could record surface climate variability in a region where rainfall is sensitive to both the strength of the intertropical convergence zone as well as Indian Monsoon variability.

    This cross-sectional study investigated the prevalence of brucellosis and bovine tuberculosis (BTB) in local cattle and goat breeds of Oromo and Afar pastoralist communities living in two distinct parts around the Awash National Park. A questionnaire survey was carried out to assess information on husbandry, milk consumption habits, and on knowledge-attitude-practice regarding both diseases. Among a total of 771 animals from all sites tested by comparative intradermal tuberculin test (CIDT) none were BTB reactors with the >4mm cut-off. Using the >2mm cut-off, individual apparent prevalence was 0.9% (95%CI: 0.23-3.56%) in cattle and 0.7% (95%CI: 0.12-3.45%) in goats. Herd prevalence in Oromia and Afar sites was 0% and 66.7% respectively in goats and 16.7% and 50% in cattle. Among the 327 animals tested by enzyme linked immunoassay for brucellosis, 4.8% (95%CI: 1.2-17.1%) of cattle and 22.8% (95%CI: 5.98-29.5%) of goats were reactors. Highest individual prevalence of both diseases was found in Afar settlements with brucellosis being as high as 50%. Respondent ethnicity was the only risk factor for brucellosis positivity in goats in the univariable risk factor analysis. Knowledge about the diseases was poor. Raw goat milk was regularly consumed by women and children, putting them at risk for brucellosis. This study highlighted an increased prevalence gradient of BTB and brucellosis from West to East along the study sites with high brucellosis individual prevalence and abortion rates among Afar settlements in particular.

    Landslide represents one of the main constraints for the development of road infrastructures in many parts of Ethiopia. While rugged topography, intra-sedimentary clay horizons, thick talus deposits at the foot of hills and wide spread tectonic fissures and faults account for the prominent inducing factors, heavy monsoon rainfall is the most common triggering factor for the majority of road failures caused by landslides. We present the results of geoelectrical investigation of a landslide that caused a severe damage to the Dedebit-Adi-Remets segment of the recently built highway that transects the high relief and mountainous region of Tigray, northern Ethiopia. Vertical Electrical Sounding (VES) measurements were taken at twelve points, systematically distributed to cover the affected area. The resulting geo-electric sections revealed that the shallow subsurface is composed of four distinct geo-electric layers. The corresponding major lithological successions, from top to bottom, are: unconsolidated conglomeratic layer, moist silty clay, moderately weathered and fractured basaltic rock and a possibly saturated portion of the basalt. Major discontinuities, indications of structural weak zones, have also been inferred based on abrupt vertical shift in geo-electrical layer boundaries between neighboring soundings. Based on the main findings, the road failure in the study area appears to be caused by a downslope movement of the subgrade composed of top unconsolidated sediment soaked with water from heavy rain. The location of the probable slip plane could be the inclined interface between the conductive clayey soil and the underlying resistive weathered basalt.

    This study aimed at determining the incidence, distribution, risk factors, and causal serotypes of foot and mouth disease (FMD) outbreaks in Ethiopia based on 5 years of retrospective outbreak data (September 2007 until August 2012). District level outbreak data were collected from 115 randomly selected districts using a questionnaire administered to district animal health officers. The national incidence of FMD outbreaks during the study period was 1.45 outbreaks per five district years. Outbreaks were geographically widespread affecting all major regional states in the country and were more frequent in the central, southern, and southeastern parts of the country. Neither long-term nor seasonal trends were observed in the incidence of outbreaks. A mixed effects logistic regression analysis revealed that the type of production system (market oriented system versus subsistence systems), presence of a major livestock market and/or route, and adjacency to a national parks or wildlife sanctuary were found to be associated with increased risk of outbreaks in the districts. FMD virus serotypes O, A, SAT 2, and SAT 1 were identified as the causal serotypes of the outbreaks during the study period. Whereas O was the dominant serotype, SAT 2 was the serotype that showed increase in relative frequency of occurrence. The estimated incidence of outbreaks is useful in assessing the economic impacts of the disease, and the identified risk factors provide important knowledge to target a progressive FMD control policy for Ethiopia.

  14. Satellites, Plasmas and Law: The Role of TeleCourt in Changing Conceptions of Justice and Authority in Ethiopia

    Zenebe Beyene

    2015-05-01

    Full Text Available An ambitious experiment in the ICT and justice sector is underway in Ethiopia. As part of an effort to improve service delivery and the responsiveness of the state, the Ethiopian government has created 'TeleCourt,' a system that allows trials to take place between remote areas and regional or federal courts through videoconferencing and a satellite Internet connection. This article is the first to analyze how TeleCourt operates, with a particular focus on the perspectives of end-users, those who have had first-hand experience of how 'justice at a distance' actually works. The findings suggest general satisfaction with the savings - both in terms of financial burden and time costs that are often incurred when travelling to trials - which TeleCourt allows. As the system improves ways to provide justice to the grassroots, in line with the government's commitment towards peasants, this must also be considered in the context of the Ethiopian government's growing efforts to use law to curb political dissent. This is indicative of a broader tendency of selectively adopting and reshaping ICTs and extending them to the poorest people in Ethiopia in order to support the functioning of the state, while other uses of ICTs that are seen as potentially destabilizing are discouraged or forbidden.

    As a result of armed civil conflict in South Sudan that started in mid-December of 2013, an estimated 1.1 million persons were internally displaced, and approximately 400,000 refugees fled South Sudan to neighboring countries (primarily to Ethiopia, Uganda, Sudan, and Kenya). Refugees from South Sudan arriving in Ethiopia are sheltered in three refugee camps located in Gambella region: Leitchuor, Kule, and Tierkidi. The camps were established during January-May 2014 and have estimated refugee populations of 47,000, 51,000, and 50,000, respectively. Reports from health clinics and humanitarian agencies providing assistance to refugees suggested poor nutritional status of arriving refugees and elevated mortality rates. To assess the nutritional status of refugee children aged 6-59 months and mortality rates (crude [all ages] and aged Refugee and Returnee Affairs (an Ethiopian government aid agency), the United Nations High Commissioner for Refugees, World Food Programme, and United Nations Children's Fund, in collaboration with CDC, conducted cross-sectional population-representative surveys in Leitchuor, Kule, and Tierkidi camps during June-July 2014. Anthropometric measurements in children were taken using standard procedures, and nutritional status was classified based on 2006 World Health Organization (WHO) growth standards. Hemoglobin was measured using HemoCue Hb 301. Anemia was diagnosed according to WHO thresholds. Retrospective mortality rates in Leitchuor and Kule were measured using a household census method.

    This presentation will highlight our experience in teaching 19 Master's students from diverse backgrounds hydrology and watershed management in Ethiopia. Although the program was based at Bahir Dar University on the shores of Lake Tana in Ethiopia, the students received an US degree. The goal was to train professionals who can help to institute more effective and sustainable watershed management practices in Ethiopia. Teaching hydrology was a challenge. From the literature and personal observation, it was obvious that the traditional techniques of predicting runoff based on infiltration excess runoff and SCS curve number method were not satisfactory. Saturation excess runoff was more likely. However there was no research to prove that it actually was the case. In class we taught both runoff principles but stressed the saturation excess runoff. It was impossible to convince the students that the techniques that came from the western world be incorrect. For their Masters thesis, eight students did field research on runoff and erosion processes in watershed (some of which has a long record of discharge and sediment data). The students recorded water table heights, measured infiltration rates and determined where most erosion took place in the landscape. Based on this data they modeled the previously observed discharge successful using a saturation excess type model. From these studies we could establish that saturation in the landscape had a great effect on both runoff and sediment losses. As result of the field work, students had changed their mind about the appropriateness of using for example the SCS curve number method in Ethiopian highlands Perhaps the lesson to be learned is that we do not need a lot of funds to teach students the right hydrology. However, there is no substitute for going out in the field and experiencing what the right hydrology is by studying the processes in the landscape itself. By simply teaching in class, students will and cannot accept

    Scenarios for future use in the pesticide registration procedure in Ethiopia were designed for 3 separate Ethiopian locations, which are aimed to be protective for the whole of Ethiopia. The scenarios estimate concentrations in surface water resulting from agricultural use of pesticides for a small stream and for two types of small ponds. Seven selected pesticides were selected since they were estimated to bear the highest risk to humans on the basis of volume of use, application rate and acute and chronic human toxicity, assuming exposure as a result of the consumption of surface water. Potential ecotoxicological risks were not considered as a selection criterion at this stage. Estimates of exposure concentrations in surface water were established using modelling software also applied in the EU registration procedure (PRZM and TOXSWA). Input variables included physico-chemical properties, and data such as crop calendars, irrigation schedules, meteorological information and detailed application data which were specifically tailored to the Ethiopian situation. The results indicate that for all the pesticides investigated the acute human risk resulting from the consumption of surface water is low to negligible, whereas agricultural use of chlorothalonil, deltamethrin, endosulfan and malathion in some crops may result in medium to high risk to aquatic species. The predicted environmental concentration estimates are based on procedures similar to procedures used at the EU level and in the USA. Addition of aquatic macrophytes as an ecotoxicological endpoint may constitute a welcome future addition to the risk assessment procedure. Implementation of the methods used for risk characterization constitutes a good step forward in the pesticide registration procedure in Ethiopia.

    Full Text Available Abstract Background Plasmodium vivax accounts for about 40% of all malaria infection in Ethiopia. Chloroquine (CQ is the first line treatment for confirmed P. vivax malaria in the country. The first report of CQ treatment failure in P. vivax was from Debre Zeit, which suggested the presence of chloroquine resistance. Methods An in vivo drug efficacy study was conducted in Debre Zeit from June to August 2006. Eighty-seven patients with microscopically confirmed P. vivax malaria, aged between 8 months and 52 years, were recruited and treated under supervision with CQ (25 mg/kg over three days. Clinical and parasitological parameters were assessed during the 28 day follow-up period. CQ and desethylchloroquine (DCQ blood and serum concentrations were determined with high performance liquid chromatography (HPLC in patients who showed recurrent parasitaemia. Results Of the 87 patients recruited in the study, one was lost to follow-up and three were excluded due to P. falciparum infection during follow-up. A total of 83 (95% of the study participants completed the follow-up. On enrolment, 39.8% had documented fever and 60.2% had a history of fever. The geometric mean parasite density of the patients was 7045 parasites/μl. Among these, four patients had recurrent parasitaemia on Day 28. The blood CQ plus DCQ concentrations of these four patients were all above the minimal effective concentration (> 100 ng/ml. Conclusion Chloroquine-resistant P. vivax parasites are emerging in Debre Zeit, Ethiopia. A multi-centre national survey is needed to better understand the extent of P. vivax resistance to CQ in Ethiopia.

    Full Text Available The study examined the determinants of domestic private investment in Ethiopia using a time series data over the period 1992-2010. The study employed an Autoregressive Distributed Lag (ARDL model and applied the bounds test approach in modeling the long run determinants of domestic private investment. The study found exchange rate, domestic saving and domestic credit as key factors having negative and significant impact on domestic private investment. External debt and government expenditure are found to have significant and positive effect on domestic private investment. The results imply that government expenditure stimulates domestic private investment while domestic credit and domestic saving have a constrained effect on the sector.

    We investigate the role of an indigenous social network in Ethiopia, the iddir, in facilitating factor market transactions among smallholder farmers. We use detailed longitudinal household survey data and employ fixed effects estimation approaches to identify the effect of iddir membership...... on factor market transactions among farmers. We find that joining an iddir network improves households’ access to land, labour and credit transactions. Our findings also hint that iddir networks may crowd-out borrowing from local moneylenders (locally referred as ‘Arata Abedari’), a relatively expensive...... credit source. These results suggest that non-market institutions can play crucial roles in facilitating market transactions....

    Full Text Available The study was conducted to identify the major reproductive health problems and its associated risk factors in indigenous Borena breed cows in Borena zone in Southern Ethiopia between September 2013 and February 2014. Out of the total 409 cows examined, 195 (47.7% were having at least one of the reproductive problems identified by either questionnaire interview (n=329 or regular follow up (n=80 of individual cows. The major reproductive health problems identified in the present study were mastitis (21.3%; n=87/409, abortion (12.2%; n=50/409, repeat breeder (10.3%; n=42/409, anestrus (10.3%; n=42/409 and retained fetal membrane (RFM; 7.6%; n=31/409. The rate of abortion increased significantly (p=0.001 with the increase in the stage of gestation. Laboratory findings indicated that brucellosis and mastitis had great roles in reproductive health problems of dairy cows in the study area with prevalence rates of 2.91% and 68.41%, respectively. In conclusion, the study revealed that several reproductive health problems such as mastitis, abortion, repeat breeder, anestrus and RFM are mostly prevalent in dairy cows in Borena zone in southern Ethiopia.

    The year 2013 marks exactly 200 years since John Snow, known as the father of modern epidemiology, was born. In 19th century, epidemiologists like John Snow, concentrated almost entirely upon infectious diseases of humans measuring the burden of disease, describing pattern and attempting to understand the transmission dynamics. During the second half of the 20th century; big changes occurred so that epidemiologists in the developed world started to use systematized approaches to investigate the etiologies, conditions and to evaluate interventions through different study designs. However, the situation in the developing world is not the same as the rest of the world. Even 200 years after Snow's birth, epidemiological capacity is lowest in Africa. This article attempts to describe that Ethiopia is not exceptional. In the past few decades, there have been some attempts to build capacity in the country by launching training programs in clinical epidemiology, general epidemiology and field epidemiology. However, not only few epidemiologists are trained, but, limited funding, high-teaching burdens, poor working conditions and low salaries are among important contributors for epidemiological brain drain in Ethiopia. Thus, strengthening learning opportunities and rewarding career paths are required to increase human resource capacity and retain skilled personnel in the field of epidemiology.

  5. Re-Greening Ethiopia: History, Challenges and Lessons

    Full Text Available In Ethiopia, deforestation rates remain high and the gap between demand and domestic supply of forest products is expanding, even though government-initiated re-greening efforts began over a century ago. Today, over 3 million hectares (ha of degraded forest land are under area exclosure; smallholder plantations cover 0.8 million ha; and state-owned industrial plantations stagnate at under 0.25 million ha. This review captures experiences related to re-greening practices in Ethiopia, specifically with regards to area exclosure and afforestation and reforestation, and distills lessons regarding processes, achievements and challenges. The findings show that farmers and non-governmental organizations (NGOs are the main players, and that the private sector has so far played only a small role. The role of the government was mixed: supportive in some cases and hindering in others. The challenges of state- and NGO-led re-greening practices are: inadequate involvement of communities; poorly defined rehabilitation objectives; lack of management plans; unclear responsibilities and benefit-sharing arrangements; and poor silvicultural practices. The lessons include: a more active role for non-state actors in re-greening initiatives; more attention to market signals; devolution of management responsibility; clear definition of responsibilities and benefit-sharing arrangements; and better tenure security, which are all major factors to success.

    Full Text Available Setting: The study was conducted in Addis Ababa, the capital city of Ethiopia. Specifically, it was conducted in all healthcare facilities offering maternity and obstetric services.Objective: The objective of the study was to explore the patterns of caesarean-section (CS delivery in Addis Ababa.Methods: A cross-sectional survey was carried out between December 2013 and January 2014. The population for the study were women aged between 15 and 19 years of age who had given birth in the last 1–3 years before the date of data collection. The Census and Survey Processing System software was used for data capturing and analysing both descriptive and inferential statistics using Statistical Package for Social Sciences version 20.0.Results: Amongst the 835 women who delivered at health facilities, 19.2% had given birth by CS. The prevalence of CS based on medical indication was 91.3%. However, 6.9% of CS performed had no medical indication. Private health facilities performed more CSs than public health facilities, 41.1% and 11.7% respectfully. CS was high amongst women of higher socioeconomic standing.Conclusion: Overall, CS deliveries rate in Ethiopia is above the rate recommended by the World Health Organisation. Because socio-economic factors influence CS delivery, governments should play a key role in regulating performance of CSs in private institutions.

    Triticale is a crop that resulted from the addition of chromosomes of wheat (Triticum aestivum ) and rye cereals (Secale cereale). The crop came on the market as bread cereal in the 1980s. Different varieties were released. Triticale is a high yielding crop when compared with tef, wheat and barley, particularly on locations with soil nutrient deficiency. The study was initiated with the question to which extent the growing of triticale crop (Triticosecale Wittmack) improves food security, and which factors can play a major role for its successful adoption, particularly in major food insecure areas of Ethiopia. The study has three main objectives: (1) to investigate the adaptability of triticale to the Ethiopian agro-ecological conditions, particularly in areas with low soil fertility, hence this is a crop considered to provide considerably a higher harvest under low agricultural inputs, such as fertilizer, insects and pests sprays; (2) to analyze the injera--and bread-baking quality of the crop in comparison with tef (a staple cereal limited to Ethiopia) and wheat cereals, and examine the acceptance by consumers of these products made from this grain. The study was conducted in the two major triticale producing districts (wereda), Farta and Estie of the South Gondar Administrative Zone in the Amhara Region, Ethiopia. The production of crops and the adoption of triticale as a new technology by smallholder farmers are influenced by several factors such as family size, age, gender and education of the household head, availability of agricultural extension services and farm credits, and labour. Despite the high yield and widespread adoption of triticale crop in the study areas and the Amhara Region at large, it faced some amount of resistance from a few farmers and some agriculturalists. This is because of the possibility of soil nutrients exploitation by the triticale plant, with a consequent drop of nutrition for the succeeding crops. This is however, a hardly valid

    Malaria is a major global public health problem, particularly in Sub-Saharan Africa. The spatial heterogeneity of malaria can be affected by factors such as hydrological processes, physiography, and land cover patterns. Tropical wetlands, for example, are important hydrological features that can serve as mosquito breeding habitats. Mapping and monitoring of wetlands using satellite remote sensing can thus help to target interventions aimed at reducing malaria transmission. The objective of this study was to map wetlands and other major land cover types in the Amhara region of Ethiopia and to analyze district-level associations of malaria and wetlands across the region. We evaluated three random forests classification models using remotely sensed topographic and spectral data based on Shuttle Radar Topographic Mission (SRTM) and Landsat TM/ETM+ imagery, respectively. The model that integrated data from both sensors yielded more accurate land cover classification than single-sensor models. The resulting map of wetlands and other major land cover classes had an overall accuracy of 93.5%. Topographic indices and subpixel level fractional cover indices contributed most strongly to the land cover classification. Further, we found strong spatial associations of percent area of wetlands with malaria cases at the district level across the dry, wet, and fall seasons. Overall, our study provided the most extensive map of wetlands for the Amhara region and documented spatiotemporal associations of wetlands and malaria risk at a broad regional level. These findings can assist public health personnel in developing strategies to effectively control and eliminate malaria in the region.

It is common in areas where people are socioeconomically deprived. Globally, approximately 1.2 billion people live in trachoma-endemic areas, in which, 40.6 million individuals have active trachoma and 8.2 million have trichiasis. According to the World Health Organization’s 2007 report, globally close to 1.3 million people are blind due to trachoma, while approximately 84 million suffer from active trachoma. The National Survey (2007 of Ethiopia showed a prevalence of 40.1% active trachoma among children aged 1–9 years. Trachoma is still endemic in most parts of Ethiopia.Objective: To assess prevalence of trachoma and factors associated with it among children aged 1–9 years in Zala district, Gamo Gofa Zone, Southern Nations, Nationalities, and Peoples’ Region.Methods: A community-based cross-sectional study was conducted in Zala district from February 28 to March 26, 2014. A total of 611 children were examined for trachoma based on the simplified World Health Organization 1983 classification. A multistage stratified sampling technique with a systematic random sampling technique was used to select study participants. Data were collected by using a semistructured pretested questionnaire and clinical eye examination. The data were entered using EpiData version 3.1 and analyzed using SPSS version 16. Multivariable logistic regression analysis was used to identify independently associated factors.Results: The overall prevalence of

    Full Text Available Abstract Background Studies indicate that there is high early mortality among patients starting antiretroviral treatment in sub-Saharan Africa. However, there is paucity of evidence on long term survival of patients on anti-retroviral treatment in the region. The objective of this study is to examine mortality and its predictors among a cohort of HIV infected patients on anti-retroviral treatment retrospectively followed for five years. Methods A retrospective cohort study was conducted among HIV infected patients on ART in eastern Ethiopia. Cox regression and Kaplan-Meier analyses were performed to investigate factors that influence time to death and survival over time. Result A total of 1540 study participants were included in the study. From the registered patients in the cohort, the outcome of patients as active, deceased, lost to follow up and transfer out was 1005 (67.2%, 86 (5.9%, 210 (14.0% and 192 (12.8% respectively. The overall mortality rate provides an incidence density of 2.03 deaths per 100 person years (95% CI 1.64 - 2.50. Out of a total of 86 deaths over 60 month period; 63 (73.3% died during the first 12 months, 10 (11.6% during the second year, and 10 (11.6% in the third year of follow up. In multivariate analysis, the independent predictors for mortality were loss of more 10% weight loss, bedridden functional status at baseline, ≤ 200 CD4 cell count/ml, and advanced WHO stage patients. Conclusion A lower level of mortality was detected among the cohort of patients on antiretroviral treatment in eastern Ethiopia. Previous history of weight loss, bedridden functional status at baseline, low CD4 cell count and advanced WHO status patients had a higher risk of death. Early initiation of ART, provision of nutritional support and strengthening of the food by prescription initiative, and counseling of patients for early presentation to treatment is recommended.

    Full Text Available BACKGROUND: Transmission of Mycobacterium tuberculosis (M. tuberculosis complex could be possible between farmers and their cattle in Ethiopia. METHODOLOGY/PRINCIPAL FINDINGS: A study was conducted in mixed type multi-purposes cattle raising region of Ethiopia on 287 households (146 households with case of pulmonary tuberculosis (TB and 141 free of TB and 287 herds consisting of 2,033 cattle belonging to these households to evaluate transmission of TB between cattle and farmers. Interview, bacteriological examinations and molecular typing were used for human subjects while comparative intradermal tuberculin (CIDT test, post mortem and bacteriological examinations, and molecular typing were used for animal studies. Herd prevalence of CIDT reactors was 9.4% and was higher (p<0.01 in herds owned by households with TB than in herds owned by TB free households. Animal prevalence was 1.8% and also higher (p<0.01 in cattle owned by households with TB case than in those owned by TB free households. All mycobacteria (141 isolated from farmers were M. tuberculosis, while only five of the 16 isolates from cattle were members of the M. tuberculosis complex (MTC while the remaining 11 were members of non-tuberculosis mycobacteria (NTM. Further speciation of the five MTC isolates showed that three of the isolates were M. bovis (strain SB1176, while the remaining two were M. tuberculosis strains (SIT149 and SIT53. Pathology scoring method described by "Vordermeier et al. (2002" was applied and the average severity of pathology in two cattle infected with M. bovis, in 11 infected with NTM and two infected with M. tuberculosis were 5.5, 2.1 and 0.5, respectively. CONCLUSIONS/SIGNIFICANCE: The results showed that transmission of TB from farmers to cattle by the airborne route sensitizes the cows but rarely leads to TB. Similarly, low transmission of M. bovis between farmers and their cattle was found, suggesting requirement of ingestion of contaminated milk from

    Full Text Available Tuberculosis (TB is a disease of public health concern, with a varying distribution across settings depending on socio-economic status, HIV burden, availability and performance of the health system. Ethiopia is a country with a high burden of TB, with regional variations in TB case notification rates (CNRs. However, TB program reports are often compiled and reported at higher administrative units that do not show the burden at lower units, so there is limited information about the spatial distribution of the disease. We therefore aim to assess the spatial distribution and presence of the spatio-temporal clustering of the disease in different geographic settings over 10 years in the Sidama Zone in southern Ethiopia.A retrospective space-time and spatial analysis were carried out at the kebele level (the lowest administrative unit within a district to identify spatial and space-time clusters of smear-positive pulmonary TB (PTB. Scan statistics, Global Moran's I, and Getis and Ordi (Gi* statistics were all used to help analyze the spatial distribution and clusters of the disease across settings.A total of 22,545 smear-positive PTB cases notified over 10 years were used for spatial analysis. In a purely spatial analysis, we identified the most likely cluster of smear-positive PTB in 192 kebeles in eight districts (RR= 2, p<0.001, with 12,155 observed and 8,668 expected cases. The Gi* statistic also identified the clusters in the same areas, and the spatial clusters showed stability in most areas in each year during the study period. The space-time analysis also detected the most likely cluster in 193 kebeles in the same eight districts (RR= 1.92, p<0.001, with 7,584 observed and 4,738 expected cases in 2003-2012.The study found variations in CNRs and significant spatio-temporal clusters of smear-positive PTB in the Sidama Zone. The findings can be used to guide TB control programs to devise effective TB control strategies for the geographic areas

    Ethiopia has made notable progress in increasing awareness and knowledge of family planning and is considered a success story among funders and program planners. Yet unmet need among rural women (28.6%) is almost double that of urban women (15.5%), with a wide gap in total fertility rate depending on urban (2.6) or rural (5.5) residence. This study investigates the impact of a service delivery model that combines community-based distribution (CBD) of contraception with social marketing in Tigray, Ethiopia, to create a more sustainable approach to CBD. Between September 2011 and October 2013, 626 volunteer CHWs were recruited and trained to administer depot medroxyprogesterone acetate (DMPA) injections and provide counseling and referrals to the health post for other methods; the project implementation period ended in June 2014. The CHWs received a supply of DMPA injections in the form of a microloan from a drug revolving fund; the CHWs charged women a minimal fee (5 birr, or US$0.29), determined based on willingness-to-pay data, for each DMPA injection; and the CHWs returned part of the fee (3 birr) to the drug revolving fund while keeping the remaining portion (2 birr). The CHWs also promoted demand for family planning through door-to-door outreach and community meetings. Existing health extension workers (HEWs) provided regular supervision of the CHWs, supplemented by in-depth supervision visits from study coordinators. Baseline and endline representative surveys of women of reproductive age, as well as of participating CHWs, were conducted. In addition, DMPA provision data from the CHWs were collected. Between October 2011 and June 2014, the CHWs served in total 8,604 women and administered an estimated 15,410 DMPA injections, equivalent to providing 3,853 couple-years of protection. There was a 25% significant increase in contraceptive use among surveyed women, from 30.1% at baseline to 37.7% at endline, with DMPA use largely responsible for this increase

    This study sought to confirm and investigate further recently published information regarding the occurrence of Neospora caninum in cattle in Ethiopia and investigate infection in dogs, the canine definitive host, in this region. Faecal samples from 383 dogs in Hawassa, Ethiopia were examined by microscopy for Neospora-like oocysts, and positive samples then analysed by a molecular approach (DNA isolation, PCR and sequencing at the ITS1 gene). Brain tissue samples from four late term aborted foetuses, one congenitally defective calf (hind leg arthrogryposis) and placental tissue from cattle in the same area were also examined by the same molecular approach. All foetal, calf and placental tissue were associated with Neospora seropositive dams. A high prevalence of Neospora-like oocysts (11.5 μm±1.5 μm diameter) was observed in faecal samples from dogs (37 positive samples; 9.7% prevalence), and in 17 of these the identification was confirmed by PCR, giving a prevalence of confirmed infection of 4.4%. N. caninum DNA was also detected in all foetal and calf brain tissue samples. Sequencing revealed only minor differences among all PCR products, whether from oocysts or from brain tissue samples. These data provide molecular evidence of the presence of N. caninum infection in both dog and cattle in this region of Ethiopia. Moreover these findings highlight the role of dogs in maintaining and spreading the infection horizontally in the study area. The high frequency of N. caninum infection in household dogs as well as farm dogs is worthy of further investigation.

    An epidemiological survey was conducted in pastoral regions of Ethiopia to investigate the distribution of brucellosis in sheep and goats. Between November 2004 and December 2007, a total of 6,201 serum samples were collected from 67 randomly selected peasant associations, 25 districts and eight pastoral zones of Ethiopia. The Rose Bengal plate test (RBPT) and complement fixation test were used in series. Samples for bacteriology were collected from three export abattoirs, where 285 goats were randomly selected and tested by RBPTthree days before slaughter. Tissue samples were collected from 14 strongly positive goats and cultured in dextrose agar and Brucella agar base. To confirm and subtype the isolates, staining, biochemical tests and polymerase chain reaction were used. The overall standardised seroprevalence of brucellosis was 1.9%, ranging from 0.07% in Jijiga zone to 3.3% in Borena zone. There was statistically significant variation among the studied regions, zones, districts and peasant associations (p goats and sheep were twice as likely to test positive as females (relative risk [RRJ: 2.04; 95% confidence interval [CI]:1.7-3.4; x2 = 21.05, p Goats were around four times more likely to be infected than sheep (RR: 3.8; 95% CI: 2.4-6.1; chi2 = 36.99, p Brucella melitensis was isolated from 2 of the 14 samples analysed. The widespread distribution of brucellosis in goats and sheep in these areas justifies the use of control measures to minimise the economic losses and public health hazards.

    Full Text Available Abstract Background The synergy between tuberculosis (TB and human immunodeficiency virus (HIV co-infection on perceived stigma is not well studied. The objective of this study was to assess the effect of TB/HIV co-infection on perceived stigma in selected hospitals of Oromiya region, Ethiopia. A cross sectional study was conducted from February to April, 2009 in Adama, Nekemet and Jimma Specialized hospitals. Data were collected by trained HIV counselors. A structured questionnaire which consisted of socio-demographic variables, clinical information, perceived stigma, and depression was used to collect the data Findings A total of 591 participants were included in the study of whom 124 (20.9% were co-infected with TB/HIV. The stigma items were highly reliable (Cronbach's alpha = 0.93 and had strong inter dimension correlation. Respondents who were co-infected with TB and HIV were more likely to have perceived stigma compared to non-co-infected HIV patients, [OR = 1.4, (95% CI: 1.2, 2.0]. Non-literate individuals [OR = 1.9, (95% CI: 1.2, 3.0] and females [OR = 1.6, (95% CI: 1.2, 2.3] had also more perceived stigma. Conclusions TB/HIV co-infected patients, non-literate individuals and females were more likely to have high perceived stigma. Behavioral Change Communication should focus on these segments of the population to rectify the high perceived stigma.

    A village-to-village search for active dracunculiasis cases was carried out in an endemic area of the Bume (Nyangaton) tribe of South Omo Region, Ethiopia. A total of 21 cases, of which 6, 5, and 10 had pre-emergent, emergent and complicated Guinea worm disease, respectively, were identified. Twenty-two worms, ranging from 1-3 per patient, were removed mainly from the lower limbs; worm appearance seems to be associated more with the right limb. Adults between the ages of 20-30 years are highly affected and infection appears to be sex-related as 14/21 (66.7%) of the cases are females. Water procured from water-holes drug in dry river beds provides an ideal situation for the transmission of dracunculiasis amongst the tribesmen. The knowledge, attitudes and perceptions of the Bume people towards the disease and the public health significance of dracunculiasis are discussed in relation to the current goal of the national and global Guinea worm eradication programme.

    The Mieso valley is a new paleoanthropological sequence located in East-Central Ethiopia. It contains Middle and Upper Pleistocene deposits with fossil and lithic assemblages in stratified deposits. This paper introduces the Middle Pleistocene archaeological sequence, attributed to the late Acheulean. Low density clusters of artefacts suggest short-term use of the landscape by Acheulean hominins. In Mieso 31, one of the excavated assemblages, refit sets indicate fragmentation of the reduction sequences and enable study of the initial stages of biface manufacture. Mieso 7, also a stratified site, is primarily characterized by a small concentration of standardized cleavers, and portrays another dimension of Acheulean technology, that related to final stages of use and discard of large cutting tools. Available radiometric dates place the Mieso Acheulean around 212 ka (thousands of years) ago, which would make this sequence among the latest evidence of the Acheulean in East Africa, in a time span when the Middle Stone Age is already documented in the region.

    In Libo Kemkem (a district of Amhara region, Ethiopia), no cases of kala-azar had ever been reported until 2005 when an outbreak occurred. Over one-third of those cases were children under 15 years of age. The aim of the present study was to determine the prevalence of Leishmania infection in children aged 4-15 years. A cross-sectional survey was conducted in 2009. Children participating in the survey were selected using a three-stage cluster sampling method. A total of 386 children were included in the study. The overall prevalence of Leishmania infection (direct agglutination test- and/or rK39 immunochromatographic test- and/or leishmanin skin test-positive subjects) in this population was 1.02% (95% confidence interval = 0-4.54), and prevalence was higher in boys and children older than 12 years. Only one case of active disease was encountered. The results suggest that the conditions responsible for the outbreak no longer reign. However, active surveillance remains necessary.

  19. Self-Supply as a Complementary Water Services Delivery Model in Ethiopia

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Self-supply, where households invest to develop their own easily-accessible water supplies, is identified as an alternative service delivery model that is potentially complementary to more highly subsidised community-level provision. The approach is widespread in Ethiopia with family wells bringing additional benefits that are in line with wider government objectives, such as supporting small-scale irrigation. However, two recent studies show the current performance of traditional or family wells to be far below potential with most sources providing unsafe water in the absence of adequate protection. Wider formal recognition of Self-supply in policy and the development of the government-led Self-supply Acceleration Programme (SSAP aim to extend access and improve aspects of performance including water quality. However, a key finding of the paper is that successful uptake of this programme requires a transformation in the attitudes of donor agencies and the roles of government regional- and woreda-level staff, amongst others. Necessary shifts in mindsets and revision of planning mechanisms, as well as the day-to-day operational support requirements, represent a challenge for an under-resourced sector. Other household-focused development interventions such as Community-led Total Sanitation (CLTS and Household Water Treatment and Storage (HWTS face some similar challenges, so the processes for the development of one approach could help in the scaling up of all.

    Complete mitochondrial and two nuclear gene sequences of a novel genotype (GOmo) related to Echinococcus granulosus sensu stricto are described from a metacestode isolate retrieved from a human patient in southwestern Ethiopia. Phylogenetically, the genotype is positioned within the E. granulosus sensu stricto/Echinococcus felidis cluster, but cannot easily be allocated to either species. Based on different mitochondrial DNA markers, it is closest to the haplotype cluster that currently defines the species E. granulosus sensu stricto (which includes variants showing the widely cited G1, G2 and G3 sequences), but is clearly not part of this cluster. Pairwise distances between GOmo and E. granulosus sensu stricto are in the range of those between the most distant members of the Echinococcus canadensis complex (G6-10) that were recently proposed as separate species. At this stage, we prefer to list GOmo informally as a genotype rather than giving it any taxonomic rank because our knowledge rests on a single isolate from a dead-end host (human), and its lifecycle is unknown. According to data on molecularly characterised Echinococcus isolates from this region, GOmo has never been found in the usual livestock species that carry cystic echinococcosis and the possibility of a wildlife source of this newly recognised zoonotic agent cannot be excluded. The discovery of GOmo adds complexity to the already diverse array of cystic echinococcosis agents in sub-Saharan Africa and challenges hypotheses on the biogeographical origin of the E. granulosus sensu stricto clade.

    Full Text Available Pre-weaning growth performances of Sekota sheep breed was studied at Sekota district of Amhara National Regional State, Ethiopia under traditional crop-livestock production systems which is characterized by extensive, low-input low-output system. Two hundred thirty one lambs were monitored from birth to weaning age. Data on growth performances were collected and analyzed using the general linear model procedures of Statistical analysis system software. The least squares mean birth weight, three months weight and average daily weight gains from birth to three months age were 2.73 kg, 11.9 kg and 101 gm, respectively. Parity and type of birth were significant sources of variation for birth weight. Location had an effect of three months weight. The results obtained revealed the potential of the breed for meat production in the prevailing environment. The effect of parity on birth weight indicates special care for lambs from maiden ewes. Management options like integrated health care and supplementation of feed for sheep during the dry season help farmers to benefit from their sheep.

    The aim of the study was to determine the prevalence of infectious keratoconjunctivitis on cross-breed dairy farms and to evaluate factors that influence its distribution. A total of 11 dairy farms and one cattle cross-breeding farm in different parts of Arsi region, south-east Ethiopia were clinically and bacteriologically investigated from February 1989 to December 1990. Out of 5221 local zebu and cross-breed dairy animals, 110 were found to have different degrees of infectious bovine keratoconjunctivitis. Of these, 94 (85.5%) were unilateral and 16 (14.5%) were bilateral. The prevalence of the disease was significantly (P 0.750). Moraxella bovis was isolated from 88 (80%) of the 110 bacteriologically positive cases. Of these isolates, 61 (69%) were haemolytic and 27 (31%) were non-haemolytic strains. Infection with M. bovis was unilateral. Concurrent infections with M. bovis included Actinomyces pyogenes 23 (21%), Staphylococcus aureus 17 (15%), Pasteurella haemolytica nine (8%), Escherichia coli eight (7%) and Proteus spp. four (3.6%).

    To measure time to initial presentation and assess factors influencing the decision to seek medical attention, we interviewed 243 patients undergoing sputum examination for the diagnosis of tuberculosis (TB) at a rural health centre near Awassa, Ethiopia. A structured questionnaire was used. Median (mean+SD) patient delay was 4.3 (9.8+12.4) weeks. Delays over 4 weeks were significantly associated with rural residence, transport time over 2 h, overnight travel, transport cost exceeding US $1.40, having sold personal assets prior to the visit, and use of traditional medicine. The majority of patients cited economic or logistical barriers to health care when asked directly about causes of delay. Case-finding strategies for TB must be sensitive to patient delay and health systems must become more accessible in rural areas.

    Full Text Available In order to combat adverse effects of farmland degradation it is necessary for farmers to adopt sustainable land management and conservation strategies like intercropping and conservation tillage. However, efforts to adopt these strategies are very minimal in Ethiopia. In an attempt to address the objectives of examining factors affecting use of intercropping and conservation tillage practices, this study utilized plot- and household-level data collected from 211 farm households and employed a bivariate probit model for its analysis. The study revealed that intercropping and conservation tillage decisions are interdependent, and that they are also significantly affected by various factors. In addition, conservation tillage and intercropping practices as short- term interventions are found to augment the long-term interventions like terraces, diversion ditches, and tree plantations. The paper highlights important policy implications that are required to encourage intercropping and conservation tillage measures.

    Full Text Available This study analyzed crime statistics of 2011/2012 with objectives to compare the characteristics of criminals based on correlates of crime such as age, gender, types of occupation, level of education, and marital status and to examine features of victimization by age and sex. The study was conducted in Oromia National Regional State. Police crime data of 2011/2012 were used. Furthermore, key informant interview was used. Descriptive statistics such as percentages, frequencies, and ratios were primarily used to analyze the aggregate police data. It is found that sociocultural and structural factors affect criminality and victimization patterns. The total number of criminals reported to and recorded by the police was 96,300, which constitute 85,100 male and 11,200 female offenders. About 37% of these criminals committed violent crime. The ratio of male to female offenders was 7.6:1. The dominance of male over female both in criminality and victimization is the extension of their social position in social structure and result of gender role socialization. Age group 19 to 30 was found to be the most criminal population with the criminal rate of 828 per 100,000 people. Unfortunately, the relationship between educational status, types of occupation/employment, and marital status on one hand and criminality on the other were less than conclusive mainly because of lack of adequate information on such variables for individual criminals and victims or the fact that the police data were only aggregate ones. Victimization rate was higher for males and 31 to 50 age category.

    Purpose The Ethiopian Paediatric HIV Cohort (EPHIC) was established to identify clinical and laboratory predictors of virological treatment failure to ultimately develop a clinical–immunological prediction rule with area under the curve of >0.80 for detecting first-line antiretroviral therapy failure (ARTF). It will also assess the performance of the current WHO guidelines for detection of first-line ARTF in children. Participants Using a prospective cohort design, HIV-infected children and adolescents below the age of 18 years are followed every 6 months with a set of clinical and laboratory parameters at 6 hospitals in southern Ethiopia. For inclusion in the cohort, children should be on or are initiating first-line antiretroviral therapy (ART) and are not on second-line ART. Virological treatment failure is taken as the gold standard for the diagnosis of treatment failure. Findings to date From October 2015 through April 2016, 628 children have been enrolled from 6 different HIV treatment centres across southern Ethiopia. The mean age at enrolment was 11.1 years and 47.6% were girls. Many of the children (88.6%) were at WHO Clinical stage 1 at time of enrolment. At enrolment, the mean duration on first-line ART was 45 months. Substitution of ART drugs was performed to nearly half (42.6%) of the cohort. Adherence as assessed with the Visual Analogue Scale was high (mean, 94.4%; SD=11.9). The median CD4 count of the cohort at enrolment was 741 with 3.1% having a value consistent with ARTF. Future plans Regular data uploads from the 6 hospitals in southern Ethiopia enable this cohort to be followed prospectively. The cohort will be completed in September 2017. The successful completion of this study will allow for better targeting of viral-load testing to those at highest risk in resource-poor settings and provide clinicians and policymakers with a practical prediction rule.

Depression is one of the most common mental disorders affecting 121 million people in the world, and it frequently goes unrecognized among patients. It is estimated that 5%–10% of the population at any given time is suffering from identifiable depression needing psychiatric or psychosocial intervention. An institution-based cross-sectional study design was implemented to determine the magnitude and associated factors of unrecognized depression among patients attending the adult medical outpatient department in Adare Hospital, Hawassa, Southern Nations, Nationalities, and Peoples’ Region, Ethiopia, among 326 patients selected using systematic random sampling technique. Data were collected using the interviewer-administered technique. A structured questionnaire was used to collect data on sociodemographic characteristics and other independent variables. Depression was assessed using the Patient Health Questionnaire 9. Data were entered and analyzed using SPSS 20. The level of significance was determined at P<0.05. About 326 patients were interviewed, of whom 186 (57.1% were males. The mean age of participant was 34 with standard deviation of ±13.1 years. Current substance users accounted for 106 (32.5% of the total participants. Of 326 respondents, 80 (24.5% had significant depressive symptoms, while the detection rate of depression by the clinician was 0%. Depression was associated with female sex (adjusted odds ratio [AOR] =1.63 [1.14–2.34], age >60 years (AOR =4

    A comprehensive petrological study has been carried out on Ethiopian mantle xenoliths entrained in Neogene-Quaternary alkaline lavas both overlying the Continental Flood Basalt area (Dedessa River - Wollega Region, Injibara - Gojam Region) and from southern Main Ethiopian Rift (MER - Mega, Sidamo Region) in order to investigate the mantle evolution from plume to rift settings. Mantle xenoliths from the plateau area (Injibara, Dedessa River) range in composition from spinel lherzolite to harzburgite and olivine websterite, showing P-T equilibration conditions in the range of 1-2 GPa/950-1050 °C. These xenoliths show flat chondrite-normalized bulk-rock REE patterns, with only few LREE-enriched samples (LaN/YbN up to 5). Clinopyroxene (cpx) REE patterns are generally flat or LREE depleted (LaN/YbN down to 0.6). Sr-Nd isotopes on separated cpx mainly show compositions (87Sr/86Sr 0.5132) approaching the Depleted Mantle end-member, or displaced (87Sr/86Sr 0.7033-0.7034; 143Nd/144Nd 0.5129-0.5128) toward the Enriched Mantle components which also characterize the Ethiopian Oligocene plateau basalts. These characteristics indicate that most xenoliths reflect complex asthenosphere/lithosphere interactions due to plume-related refertilization processes, whose agents may be envisaged as mafic subalkaline melts that infiltrated and reacted with the pristine parageneses ultimately leading to the formation of olivine-websterite domains. On the other hand, mantle xenoliths from southern MER (Mega) consist of spinel lherzolite to harzburgites showing various degree of deformation and recrystallization coupled with an extremely wide incompatible element distribution. Bulk rock Rare Earth Element (REE) patterns show generally flat HREE ranging from 0.1 x chondrite (ch) in harzburgites up to 2 x ch in fertile lherzolites, and are variably enriched in LREE, with LaN/YbN up to 41.5. The constituent clinopyroxenes have flat HREE distribution and LaN/YbN between 0.1 and 55, in general

    Despite large numbers of very visible active volcanoes in sub-Saharan Africa, data about eruptions are limited compared to elsewhere in the world. We present the method and findings from elicitations carried out to characterise likely future eruptions in the region as part of a World Bank GFDRR risk profiling project for sub-Saharan Africa. The purpose of the elicitations was to better understand the characteristics and frequencies of explosive eruptions at volcanoes in Ethiopia and Kenya. The elicitations will provide source parameters for tephra fall modelling at select volcanoes in Ethiopia (Aluto, Corbetti, Fentale) and Kenya (Menegai, Longonot, Suswa). There were two stages of elicitation: 1) a 'sanity check' of initial assumptions around likely eruption style, magnitude and frequency for the six selected volcanoes; 2) a formal SHELF (SHeffield ELicitation Framework) elicitation that centred round establishing frequency-magnitude relationships for the volcanoes. The elicitation suggested that explosive eruptions at Aluto and Corbetti were less likely than at the other volcanoes, although the uncertainty was significant. Menengai and Rungwe volcano in Tanzania (elicited as an analogue for Fentale, Longonot and Suswa volcanoes) were characterised by approximately similar probabilities of eruption. However, Rungwe was considered more likely to produce larger explosive (VEI ≥ 4) eruptions than Menengai. Elicitation discussions highlighted the knowledge and data gaps for African volcanoes and raised important questions around whether gaps in the eruption record were real and related to changing regimes at the volcanoes over time or if they were a function of under-recording or lack of preservation. Further investigation is therefore needed to validate the findings of the elicitation. It is hoped that continued collaboration with local partners and studies within the ongoing NERC-funded RiftVolc project will address these issues and help to improve our knowledge

    Full Text Available A total of fifteen samples of green coffee (Coffea arabica L. beans from the major producing region of Hararghe Ethiopia were studied using UV-Vis spectrometer measurement caffeine quantitative analysis from coffee beans. The number density of caffeine in green coffee beans has been reported using Beer-Lambert’s law and integrating absorption coefficient technique. Our results obtained using integrated absorption and Beer-Lambert’s law has a good agreement and we observed a maximum difference of 10.4 %. Based on their low caffeine concentrations among the samples collected were found in Jarso coffee. Coffee beans from the Harar Aboker were characterized by higher concentrations of caffeine. The determined concentration for caffeine in coffee beans (% w/w ranged 0.601 % to 0.903 %. The concentrations of the caffeine varied significantly, depending on the geographical origin of the beans. The concentrations of caffeine in coffee collected from in Hararghe region were noticeably lower than their counterpart (1.0 - 1.2 % grows in the other parts of Ethiopia.

    Although waste from coffee processing is a valuable resource to make biogas, compost, and nutrient-rich animal food, it is usually dumped into nearby water courses. We carried out water quality assessment at 44 sampling sites along 18 rivers that receive untreated waste from 23 coffee pulping and processing plants in Jimma Zone, Ethiopia. Twenty upstream sampling sites free from coffee waste impact served as control, and 24 downstream sampling sites affected by coffee waste were selected for comparison. Physicochemical and biological results revealed a significant river water quality deterioration as a result of disposing untreated coffee waste into running water courses. During coffee-processing (wet) season, the highest organic load (1,900 mg/l), measured as biochemical oxygen demand, depleted dissolved oxygen (DO) to a level less than 0.01 mg/l, and thus curtailed nitrification. During off season, oxygen started to recuperate and augmented nitrification. The shift from significantly elevated organic load and reduced DO in the wet season to increased nitrate in the off season was found to be the determining factor for the difference in macroinvertebrate community structure as verified by ordination analysis. Macroinvertebrate diversity was significantly reduced in impacted sites during the wet season contrary to the off season. However, there was a significant difference in the ratio of sensitive to pollution-tolerant taxa in the off season, which remained depreciated in the longer term. This study highlights the urgency of research exploring on the feasibility of adopting appropriate pollution abatement technologies to implement ecologically sound coffee-processing systems in coffee-growing regions of Ethiopia.

    Full Text Available BACKGROUND: In northern Ethiopia the prevalence of visceral leishmaniasis is steadily rising posing an increasing public health concern. In order to develop effective control strategies on the transmission of the disease it is important to generate knowledge on the epidemiological determinants of the infection. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cross-sectional survey on children 4-15 years of age using a multi staged stratified cluster sampling on high incidence sub-districts of Amhara regional state, Ethiopia. The survey included a socio-demographic, health and dietary questionnaire, and anthropometric measurements. We performed rK39-ICT and DAT serological tests in order to detect anti-Leishmania antibodies and carried out Leishmanin Skin Test (LST using L.major antigen. Logistic regression models were used. Of the 565 children surveyed 56 children were positive to infection (9.9%. The individual variables that showed a positive association with infection were increasing age, being male and sleeping outside [adjusted odds ratios (95% CI: 1.15 (1.03, 1.29, 2.56 (1.19, 5.48 and 2.21 (1.03, 4.71 respectively] and in relation to the household: past history of VL in the family, living in a straw roofed house and if the family owned sheep [adjusted OR (95% CI: 2.92 (1.25, 6.81, 2.71 (1.21, 6.07 and 4.16 (1.41, 12.31 respectively]. CONCLUSIONS/SIGNIFICANCE: A behavioural pattern like sleeping outside is determinant in the transmission of the infection in this area. Protective measures should be implemented against this identified risk activity. Results also suggest a geographical clustering and a household focalization of the infection. The behaviour of the vector in the area needs to be clarified in order to establish the role of domestic animals and house materials in the transmission of the infection.

  20. The He isotope composition of the earliest picrites erupted by the Ethiopia plume, implications for mantle plume source

    Stuart, Finlay; Rogers, Nick; Davies, Marc

    2016-04-01

    The earliest basalts erupted by mantle plumes are Mg-rich, and typically derived from mantle with higher potential temperature than those derived from the convecting upper mantle at mid-ocean ridges and ocean islands. The chemistry and isotopic composition of picrites from CFB provide constraints on the composition of deep Earth and thus the origin and differentiation history. We report new He-Sr-Nd-Pb isotopic composition of the picrites from the Ethiopian flood basalt province from the Dilb (Chinese Road) section. They are characterized by high Fe and Ti contents for MgO = 10-22 wt. % implying that the parent magma was derived from a high temperature low melt fraction, most probably from the Afar plume head. The picrite 3He/4He does not exceed 21 Ra, and there is a negative correlation with MgO, the highest 3He/4He corresponding to MgO = 15.4 wt. %. Age-corrected 87Sr/86Sr (0.70392-0.70408) and 143Nd/144Nd (0.512912-0.512987) display little variation and are distinct from MORB and OIB. Age-corrected Pb isotopes display a significant range (e.g. 206Pb/204Pb = 18.70-19.04) and plot above the NHRL. These values contrast with estimates of the modern Afar mantle plume which has lower 3He/4He and Sr, Nd and Pb isotope ratios that are more comparable with typical OIB. These results imply either interaction between melts derived from the Afar mantle plume and a lithospheric component, or that the original Afar mantle plume had a rather unique radiogenic isotope composition. Regardless of the details of the origins of this unusual signal, our observations place a minimum 3He/4He value of 21 Ra for the Afar mantle plume, significantly greater than the present day value of 16 Ra, implying a significant reduction over 30 Myr. In addition the Afar source was less degassed than convecting mantle but more degassed than mantle sampled by the proto-Iceland plume (3He/4He ~50 Ra). This suggests that the largest mantle plumes are not sourced in a single deep mantle domain with a

    Full Text Available ABSTRACTObstetric fistula (OF is one of the major potential complications of childbirth mostly young women in developing countries including Ethiopia. Though few scientific studies have been conducted related to its causes and consequences, it is challenging to find a comprehensive figure about obstetric fistula in Ethiopia. Therefore, this paper sought that to review the causes and consequences of obstetric fistula in Ethiopia. A number of relevant obstetrics and gynaecology websites and journals were reviewed. Google, Pubmed, and Hinari searching engines were used to find out relevant references. Year of publication, location, language and its type of publication were the inclusion criteria used for reviewing literatures. It is observed that obstetric fistula has been a major burdened mainly for women in the rural Ethiopian and its causes and consequences are very deep and diverse. The great majority of obstetric fistula causes in Ethiopia is due to Obstetric labour. Distance to the health care facility, transportation access, economic factors (poverty, poor knowledge related to the problem, poor health seeking behaviour of the affected women and age at first marriage are the other triggering factors. Stigma and discrimination of obstetric fistula patients by their husbands and families, economic dependency and psychological disorder are often mentioned as consequences for OF patients in Ethiopia.

    Full Text Available This study examines the agronomic response, efficiency and profitability of fertilizer microdosing in maize. An experiment with the following treatments was conducted: control without fertilizer, microdosing treatments, with the rate of 27 + 27, 53 + 53 and 80 + 80 kg ha−1, and banding of fertilizer with 100 + 100 kg ha−1 of di ammonium phosphate (DAP + urea, applied at planting and jointing, respectively. The treatments were arranged in a randomized complete block design with four replications. The experiment was conducted during the 2011/2012 and 2012/2013 cropping seasons at Ziway, Melkassa and Hawassa in the semiarid central rift valley region of Ethiopia. Compared to the control, the fertilizer treatments had higher yield and fertilizer use efficiency (FUE profitably. The 27 + 27 kg ha−1 fertilizer rate increased the grain yield by 19, 45 and 46% at Hawassa, Ziway and Melkassa, respectively, and it was equivalent to the higher rates. The value cost ratio (VCR was highest with the lowest fertilizer rate, varying between seven and 11 in the treatment with 27 + 27 kg ha−1, but two and three in the banding treatment. Similarly, FUE was highest with the lowest fertilizer rate, varying between 23 and 34 kg kg−1 but 7 and 8 kg kg−1 in the banding treatment. The improved yield, FUE, VCR and gross margin in maize with microdosing at the 27 + 27 kg ha−1 of DAP + urea rate makes it low cost, low risk, high yielding and profitable. Therefore, application of this particular rate in maize may be an option for the marginal farmers in the region with similar socioeconomic and agroecological conditions.

Results The informants categorized the vegetation into five community types based on plant density and associated landform: 'Raqqa', 'Hakka cadanaba', 'Mancchha', 'Bullukko', and 'Wodae gido'. 155 plant species were collected from the natural vegetation and 65 plant species from the home gardens ('Gattae Oduma'. Seventy-two plant species were documented as having medicinal value: Sixty-five (71% from natural vegetation and 27 (29% from home gardens. Forty-five (62% were used for humans, 15(21% for livestock and 13(18% for treating both human and livestock ailments: 35 (43.2% were Shrubs, 28(34.5% herbs, 17 (20.9% trees and 1(1.2% climbers. The root (35.8% was the most commonly used plant part. The category: malaria, fever and headache had the highest 0.82 ICF. Agricultural expansion (24.4% in the area was found to be the main threat for medicinal plants followed by fire wood collection (18.8%. Peoples' culture and spiritual beliefs somehow helped in the conservation of medicinal plants. Conclusion Traditional healers still depend largely on naturally growing plant species and the important medicinal plants are under threat. The documented medicinal plants can serve as a basis for further studies on the regions medicinal plants knowledge and for

    Although ticks are widely distributed in all agro-ecological zones of Ethiopia, information on tick-borne pathogens is scarce. This study was conducted to determine the presence of Anaplasma spp., Ehrlichia spp., and Rickettsia spp. in Rhipicephalus evertsi and Rhipicephalus (Boophilus) decoloratus collected from cattle and sheep at Bako, western Oromia, Ethiopia, using polymerase chain reaction and sequencing. Anaplasma ovis and Anaplasma spp., Ehrlichia ruminantium and Ehrlichia spp. were detected in Rh. decoloratus, whereas only A. ovis was detected in Rh. evertsi. Both tick species were found to harbor DNA belonging to Rickettsia spp., and Rickettsia africae. Our findings highlight the risk of infection of animals and humans with these zoonotic tick-borne bacteria in Ethiopia.

    Full Text Available This study was conducted to determine the prevalence of cystic echinococcosis (CE in small ruminants and humans in Addis Ababa, central Ethiopia. A cross-sectional study involving systematic random sampling was conducted to estimate the prevalence of CE in 512 small ruminants (262 sheep and 250 goats slaughtered at Addis Ababa Abattoir Enterprise between October 2011 and March 2012. Hydatid cysts were identified macroscopically during postmortem examination and their fertility and viability were determined. CE was observed in 21 (8.02% sheep and 17 (6.80% goats. In sheep 13 (4.96% of the lungs, 10 (3.81% livers and 1 (0.381% heart were found to be infected with hydatid cysts. Involvement of lung and liver in goats was found to be 10 (4.0% and 8 (3.2% respectively, with no cysts recorded in the heart. Of the total of 77 and 47 cysts encountered in sheep and goats, 33 (42.85% and 15 (31.91% respectively were fertile. Viability of protoscoleces from fertile cysts in sheep (29 [87.87%] was higher than in goats (6 [40.0%]. For humans, retrospective analysis covering five years of case reports at two major hospitals in Addis Ababa between January 2008 and December 2012 showed that of the total of 25 840 patients admitted for ultrasound examination, 27 CE cases were registered, a prevalence of 0.1% and mean annual incidence rate of approximately 0.18 cases per 100 000 population. Liver was the major organ affected in humans (81.5% in affected patients followed by spleen (11.1% and kidney (7.4%. Logistic regression analysis showed that prevalence of CE varied significantly in relation to host age in the small ruminants (OR = 3.93, P < 0.05 as well as in humans (95% CI, R = 4.8. This epidemiological study confirms the importance of CE in small ruminants and humans in central Ethiopia, emphasising the need for integrated approaches to controlling this neglected preventable disease.

    Inadequate management of healthcare waste is a serious concern in many developing countries due to the risks posed to human health and the environment. This study aimed to evaluate healthcare waste management in Hawassa city, Ethiopia. The study was conducted in nine healthcare facilities (HCFs) including hospitals (four), health centres (two) and higher clinics (three) in two phases, first to assess the waste management aspect and second to determine daily waste generation rate. The result showed that the median quantity of waste generated at the facilities was 3.46 kg bed(-1) day(-1) (range: 1.48-8.19 kg bed(-1) day(-1)). The quantity of waste per day generated at a HCF increased as occupancy increased (p waste generated at government HCFs was more than at private HCFs (p waste (20-63.1%) generated at the different HCFs was much higher than the WHO recommendation (10-25%). There was no waste segregation in most HCFs and only one used a complete color coding system. Solid waste and wastewater were stored, transported, treated and disposed inappropriately at all HCFs. Needle-stick injuries were prevalent in 25-100% of waste handlers employed at these HCFs. Additionally, low levels of training and awareness of waste legislation was prevalent amongst staff. The study showed that management of healthcare waste at HCFs to be poor. Waste management practices need to be improved through improved legislation and enforcement, and training of staff in the healthcare facilities in Hawassa.

    Old topographic map published in 1975 elaborated from aerial photographs taken in 1972, Landsat TM data acquired in May 1986 and Landsat ETM+ from June 2002 have been used to assess the changes of the lake Aba Samuel in Ethiopia. First map of the lake has been done in the framework of UNDP project running in 1988-90 in the Ethiopian Mapping Authority. The second classification map has been done as M.Sc. thesis in the MUT in 2015. Supervised classification methods with the use of ground truth data have been used for elaboration of the Landsat TM data. From the year 1972 up to 1986 the area of the lake has decreased by 23%. From 1986 up to 2002 the area of the lake has decreased by 20%. Therefore, after 30 years the lake was smaller by 43%. This have had very bad influence on the lives of the local population. From other recent data in the period from 2002-2015 the lake has practically disappeared and now it is only a small part of the river Akaki. ENVI 5.2 and ERDAS IMAGINE 9.2 have been used for Radiometric Calibration, Quick Atmospheric Correction (QUAC) and supervised classification of Landsat ETM+ data. The Optimum Index Factor shows the best combination of Landsat TM and ETM+ bands for color composite as 1,4,5 in the color filters: B, G, R for the signature development.

    The shield volcano Erta'Ale, situated in the Danakil Depression, Ethiopia, is known for its active lava lake. In February 2001, our team visited this lake, located inside an 80-m-deep pit, to perform field temperature measurements. The distribution and variation of temperature inside the lake were obtained on the basis of infrared radiation measurements performed from the rim of the pit and from the lake shores. The crust temperature was also determined from the lake shores with a thermocouple to calibrate the pyrometer. We estimated an emissivity of the basalt of 0.74 from this experiment. Through the application of the Stefan-Boltzmann law, we then obtained an estimate of the total radiative heat flux, constrained by pyrometer measurements of the pit, and visual observations of the lake activity. Taking into account the atmospheric convective heat flux, the convected magma mass flux needed to balance the energy budget was subsequently derived and found to represent between 510 and 580 kg s-1. The surface circulation of this mass flux was also analyzed through motion processing techniques applied to video images of the lake.

    Full Text Available In sub-Saharan Africa, motor pump irrigation is at an earlier stage than in Asia but is growing rapidly in many countries. The focus of both policy and research in Africa to date has been on facilitating supply chains to make pumps available at a reasonable price. In Africa, pump irrigation is mainly based on two sources: shallow groundwater aquifers and small streams and rivers. Both usually have limited and variable yields. We present a case study from Ethiopia where pump irrigation based on small rivers and streams is expanding rapidly, and draw parallels to experiences in Asia and other African countries. We show that while farmers understand the social nature of community-managed irrigation, they share with policymakers a narrow understanding of pump irrigation as being primarily 'technical'. They perceive pumps as liberating them from the 'social' limitations of traditional communal irrigation. However, the rapid expansion of pump irrigation is leading to increasing competition and conflict over the limited water resource. We analyse the wider implications for Africa of this blindness to the social dimension of pump irrigation and offer suggestions on future policy and applied research to address the problem before it becomes a widespread crisis.

  10. Fertilizer supply chain in Ethiopia: structure, performance and policy analysis

    2015-07-01

    Full Text Available In Ethiopia, less than 40% of farmers use fertilizer and those who do, apply rates significantly below those recommended. This low fertilizer use is primarily due to prices being two to three times higher than prices on the world markets. Reducing the price of fertilizer requires a sound understanding of the product´s supply chain. This study investigates whether fertilizer is delivered to farmers in an efficient way and at the lowest possible costs using an institutional economics framework. It was conducted in the Arsi zone and relied on secondary data as well as primary data collected through interviews. The findings point out the presence of several formal and informal institutions regulating the market. A market monopoly at each stage of the supply chain and a striking correspondence between the central organization of the chain and the rise in left-over stocks were observed. This pinpoints the imperfect structure of the chain and a misallocation of resources locked up in fertilizer stockholding. In order to improve the demand estimation procedure, this study suggests that incentives should be instituted to enhance the reliability of the information transferred along the process. Additionally, expert knowledge used in the process should be well documented, stock inventories should not be limited to central warehouses and stockholding needs to be reduced.

    By drawing upon data collected through in-depth interviews with 20 victims of the Ethio-Eritrean war, this paper addresses how psychosocial consequences of political war are expressed and conceptualized by people from Tigray, Ethiopia. War events were typically described in terms of their negative impacts on the household's means for income generation, and psychosocial complaints centred on aspects of impaired post-war economy rather than on politically violent experiences. The most reported complaints were (a) household erosion complaints, (b) social marginalization complaints and (c) education abortion complaints. Post-war psychosocial health problems were perceived as consequences of these aspects of impaired household economy, and were described in terms of their negative impacts on future income generation. Informants' expressions of distress were found to be highly informed by the socio-cultural and socio-economic structures of the Tigrayan society. Being the only study of its kind from this context, the study provides a unique illustration of the limitations of western trauma measures and calls for a context-based conceptualization of trauma.

    The impact of climatic change can be on specific locations. However, the broader the affected area coverage, in mind, the higher would be the chance in missing critical details. In this light, this paper attempts to assess the possible climatic changes and their corresponding implications on agricultural production in northern Ethiopia. The analysis is based on the future (2030 and 2050) temperature and rainfall data, downscaled as ensemble of four general circulation models (GCMs) using the A2 and B1 emission scenarios for ten meteorological stations located in different agroecological zones of the study region. The result indicates that, based on emission scenarios, the mean maximum and minimum temperature would increase by 2-2.3 and 0.8-0.9 °C in 2030 and by 2.2-2.7 and 1.4-1.7 °C in 2050, respectively. This will be accompanied by an increase in the frequency of hot days and nights and a decrease in cool days and nights. While annual rainfall totals will remain unchanged, main rainy season ( kiremt) rainfall total would increase on average in 12.9 and 14.2 % under A2 and 9.5 and 11.2 % under B1 by 2030 and 2050, respectively. Owing to an increase in kiremt rainfall, the yield of maize and sorghum may increase at some sites under future climatic conditions, and the increase would be higher under CO2 fertilization. The results suggest the need for site-specific adaptation strategies to reduce the impact and/or exploit the opportunities of climate change.

    Full Text Available Abstract An ethnobotanical study was conducted from October 2005 to June 2006 to investigate the uses of medicinal plants by people in Zegie Peninsula, northwestern Ethiopia. Information was gathered from 200 people: 70 female and 130 males, using semistructured questionnaire. Of which, six were male local healers. The informants, except the healers, were selected randomly and no appointment was made prior to the visits. Informant consensus factor (ICF for category of aliments and the fidelity level (FL of the medicinal plants were determined. Sixty-seven medicinal plants used as a cure for 52 aliments were documented. They are distributed across 42 families and 64 genera. The most frequently utilized plant part was the underground part (root/rhizome/bulb (42%. The largest number of remedies was used to treat gastrointestinal disorder and parasites infections (22.8% followed by external injuries and parasites infections (22.1%. The administration routes are oral (51.4%, external (38.6%, nasal (7.9%, and ear (2.1%. The medicinal plants that were presumed to be effective in treating a certain category of disease, such as 'mich' and febrile diseases (0.80 had higher ICF values. This probably indicates a high incidence of these types of diseases in the region, possibly due to the poor socio-economic and sanitary conditions of this people. The medicinal plants that are widely used by the local people or used as a remedy for a specific aliment have higher FL values (Carissa spinarum, Clausena anisata, Acokanthera schimperi, Calpurnia aurea, Ficus thonningii, and Cyphostemma junceum than those that are less popular or used to treat more than one type of aliments (Plumbago zeylanicum, Dorstenia barnimiana.

    Abebaw Gebeyehu Worku

    Full Text Available BACKGROUND: Maternal complications are morbidities suffered during pregnancy through the postpartum period of 42 days. In Ethiopia, little is known about women's experience of complications and their care-seeking behavior. This study attempted to assess experiences related to obstetric complication and seeking assistance from a skilled provider among women who gave birth in the last 12 months preceding the study. METHODS: This study was a cross-sectional survey of women who gave birth within one year preceding the study regardless of their delivery place. The study was carried out in six selected districts in North Gondar Zone, Amhara Region. Data was collected house-to-house in 12 selected clusters (kebeles using a pretested Amharic questionnaire. During the survey, 1,668 women were interviewed. Data entry was done using Epi Info version 3.5.3 and was exported to SPSS for analysis. Logistic regression was applied to control confounders. RESULTS: Out of the total sample, 476 women (28.5%, 95% CI: 26.4%, 30.7% reported some kind of complication. The most common complications reported were; excessive bleeding and prolonged labor that occurred mostly at the time of delivery and postpartum period. Out of the total women who faced complications, 248 (52.1%, 95% CI: 47.6%, 56.6% sought assistance from a skilled provider. Inability to judge the severity of morbidities, distance/transport problems, lack of money/cost considerations and use of traditional options at home were the major reasons for not seeking care from skilled providers. Belonging to a wealthier quintile, getting antenatal care from a skilled provider and agreement of a woman in planning for possible complications were significantly associated with seeking assistance from a skilled provider. CONCLUSION: Nearly half of the women who faced complications did not use skilled providers at the time of obstetric complications. Cognitive, geographic, economic and cultural barriers were involved

    Full Text Available BACKGROUND: Malaria elimination requires successful nationwide control efforts. Detecting the spatiotemporal distribution and mapping high-risk areas are useful to effectively target pockets of malaria endemic regions for interventions. OBJECTIVE: The aim of the study was to identify patterns of malaria distribution by space and time in unstable malaria transmission areas in northwest Ethiopia. METHODS: Data were retrieved from the monthly reports stored in the district malaria offices for the period between 2003 and 2012. Eighteen districts in the highland and fringe malaria areas were included and geo-coded for the purpose of this study. The spatial data were created in ArcGIS10 for each district. The Poisson model was used by applying Kulldorff methods using the SaTScan™ software to analyze the purely temporal, spatial and space-time clusters of malaria at a district levels. RESULTS: The study revealed that malaria case distribution has spatial, temporal, and spatiotemporal heterogeneity in unstable transmission areas. Most likely spatial malaria clusters were detected at Dera, Fogera, Farta, Libokemkem and Misrak Este districts (LLR =197764.1, p<0.001. Significant spatiotemporal malaria clusters were detected at Dera, Fogera, Farta, Libokemkem and Misrak Este districts (LLR=197764.1, p<0.001 between 2003/1/1 and 2012/12/31. A temporal scan statistics identified two high risk periods from 2009/1/1 to 2010/12/31 (LLR=72490.5, p<0.001 and from 2003/1/1 to 2005/12/31 (LLR=26988.7, p<0.001. CONCLUSION: In unstable malaria transmission areas, detecting and considering the spatiotemporal heterogeneity would be useful to strengthen malaria control efforts and ultimately achieve elimination.

    The Main Ethiopian Rift Valley encompasses a number of volcanoes, which are known to be actively deforming with reoccurring periods of uplift and setting. One of the regions where temporal changes take place is the Aluto volcanic complex. It hosts a productive geothermal field and the only currently operating geothermal power plant of Ethiopia. We carried out magnetotelluric (MT) measurements in early 2012 in order to identify the source of unrest. Broad-band MT data (0.001-1000 s) have been acquired at 46 sites covering the expanse of the Aluto volcanic complex with an average site spacing of 1 km. Based on this MT data it is possible to map the bulk electrical resistivity of the subsurface down to depths of several kilometres. Resistivity is a crucial geophysical parameter in geothermal exploration as hydrothermal and magmatic reservoirs are typically related to low resistive zones, which can be easily sensed by MT. Thus by mapping the electrical conductivity one can identify and analyse geothermal systems with respect to their temperature, extent and potential for production of energy. 3-D inversions of the observed MT data from Aluto reveal the typical electrical conductivity distribution of a high-enthalpy geothermal system, which is mainly governed by the hydrothermal alteration mineralogy. The recovered 3-D conductivity models provide no evidence for an active deep magmatic system under Aluto. Forward modelling of the tippers rather suggest that occurrence of melt is predominantly at lower crustal depths along an off-axis fault zone a few tens of kilometres west of the central rift axis. The absence of an active magmatic system implies that the deforming source is most likely situated within the shallow hydrothermal system of the Aluto-Langano geothermal field.

    The taxonomic diversity of thirty-seven Rhizobium strains, isolated from nodules of leguminous trees and herbs growing in Ethiopia, was studied using multilocus sequence analyses (MLSA) of six core and two symbiosis-related genes. Phylogenetic analysis based on the 16S rRNA gene grouped them into five clusters related to nine Rhizobium reference species (99-100% sequence similarity). In addition, two test strains occupied their own independent branches on the phylogenetic tree (AC86a2 along with R. tibeticum; 99.1% similarity and AC100b along with R. multihospitium; 99.5% similarity). One strain from Milletia ferruginea was closely related (>99%) to the genus Shinella, further corroborating earlier findings that nitrogen-fixing bacteria are distributed among phylogenetically unrelated taxa. Sequence analyses of five housekeeping genes also separated the strains into five well-supported clusters, three of which grouped with previously studied Ethiopian common bean rhizobia. Three of the five clusters could potentially be described into new species. Based on the nifH genes, most of the test strains from crop legumes were closely related to several strains of Ethiopian common bean rhizobia and other symbionts of bean plants (R. etli and R. gallicum sv. phaseoli). The grouping of the test strains based on the symbiosis-related genes was not in agreement with the housekeeping genes, signifying differences in their evolutionary history. Our earlier studies revealing a large diversity of Mesorhizobium and Ensifer microsymbionts isolated from Ethiopian legumes, together with the results from the present analysis of Rhizobium strains, suggest that this region might be a potential hotspot for rhizobial biodiversity.

    2013-11-01

    Full Text Available BACKGROUND: Visceral leishmaniasis is a lethal parasitic disease transmitted by phlebotomine sand flies. The largest focus of VL in Ethiopia is located in the lowland region bordering Sudan, where the epidemiology is complicated by the presence of thousands of seasonal agricultural workers who live under precarious conditions. METHODOLOGY/PRINCIPAL FINDINGS: We conducted two parallel case-control studies to identify factors associated with VL risk in residents and migrants. The studies were conducted from 2009 to 2011 and included 151 resident cases and 157 migrant cases, with 2 matched controls per case. In multivariable conditional regression models, sleeping under an acacia tree at night (odds ratios (OR 5.2 [95% confidence interval 1.7-16.4] for residents and 4.7 [1.9-12.0] for migrants, indicators of poverty and lower educational status were associated with increased risk in both populations. Strong protective effects were observed for bed net use (OR 0.24 [0.12-0.48] for net use in the rainy season among residents, OR 0.20 [0.10-0.42] for any net use among migrants. For residents, living in a house with thatch walls conferred 5-fold and sleeping on the ground 3-fold increased risk. Among migrants, the risk associated with HIV status was borderline significant and sleeping near dogs was associated with 7-fold increased risk. CONCLUSIONS/SIGNIFICANCE: Preventive strategies should focus on ways to ensure net usage, especially among migrant workers without fixed shelters. More research is needed to understand migration patterns of seasonal labourers and vector bionomics.

    Full Text Available BACKGROUND: In 2006 there were an estimated 645,000 people in Amhara, Ethiopia, with trachomatous trichiasis (TT who needed surgery. Despite an extensive integrated eye care worker training programme (IECW and robust support for TT surgical services, productivity has not reached targets. We investigated why surgeon productivity was below target. METHODOLOGY/PRINCIPAL FINDINGS: Confidential interviews were conducted in person with TT surgeons trained from 24 selected districts in Amhara Region and their supervisors. Determinants of attrition and productivity were investigated. We interviewed 225 people who had received IECW training; 139 (59% had subsequently changed career/job. Staff retention was associated with good road access to their health centre, mobile telephone network and a shorter time from initial training. Amongst the 94 IECW still working in the programme, the average number of patients operated was 41/year, which was mostly (86% done through outreach campaigns and only 14% of cases were performed in the static facilities where they routinely worked. Spot checks were made of surgical instruments and consumables: only 3/94 IECW had the minimum instruments and consumables to perform surgery. The main barriers to operating were lack of time, shortage of consumables, lack of patients, lack of support and equipment problems. Very few IECW received ongoing supervision or active management. CONCLUSIONS/SIGNIFICANCE: Surgeon attrition rates are high. Vertical surgery campaigns were effective in treating large numbers of cases, whilst static-site service productivity was low. Good health system management is key to building a well-staffed and well-run service.

    While there is a general consensus that using dairy technologies, such as improved breeds of dairy cows, can substantially increase farm productivity and income, adoption of such technologies has been generally low in developing countries. The underlying reasons for non-adoption of beneficial technologies in the dairy sector are not fully understood. In this study, we characterised adopters and non-adopters of dairy technologies in Ethiopia and Kenya based on farmers' resources ownership in order to identify why many farmers in Ethiopia and Kenya have not adopted improved dairy technologies. As compared to non-adopters, farmers who adopt dairy technology own relatively more farm resources. The result signals that differences in resource endowments could lead to divergent technology adoption scenarios. Results show that a higher proportion of sample smallholders in Kenya have adopted dairy technologies than those in Ethiopia. Except for the use of veterinary services, fewer than 10% of sample farmers in Ethiopia have adopted dairy technologies-less than half the number of adopters in Kenya. The higher level of dairy technology adoption in Kenya can be ascribed partly to the long history of dairy development, including improvements in the value chain for the delivery of inputs, services and fluid milk marketing. Interventions that deal with the constraints related to access to farm resources and input and output markets could facilitate uptake of dairy technology in developing countries.

  20. Globalization of psychology: Implications for the development of psychology in Ethiopia.

    Science.gov (United States)

    Swancott, Rachel; Uppal, Gobinderjit; Crossley, Jon

    2014-10-01

    The present article reports on the variation of mental health resources across the globe and considers the merits or otherwise of the process of globalization in low- and middle-income countries (LMIC), with a specific emphasis on Ethiopia. Although globalization has gained momentum in recent years, there is a concern that the globalization of Western mental health frameworks is problematic, as these concepts have been developed in a different context and do not accommodate the current diversity in understanding in LMIC countries. The importance of understanding the mental health frameworks of LMIC like Ethiopia, prior to considering if and how aspects of high-income countries (HIC) conceptualizations may be appropriately imported, is therefore reflected upon. Traditional approaches in managing mental health difficulties and possible reasons for the limited engagement with clinical psychology in Ethiopia are considered. Current developments within the fields of mental health and clinical psychology in Ethiopia are discussed, and the need to develop more local research in order to increase understanding and evaluate treatment interventions is recognized. Further consideration and debate by Ethiopian mental health professionals as well as those from HIC are recommended, to promote both reciprocal learning and new local discourses about mental health.

  10. Human papillomavirus related cervical cancer and anticipated vaccination challenges in Ethiopia.

    Science.gov (United States)

    Gebremariam, TeweldeTesfaye

    2016-01-01

    Cervical cancer is the leading cause of cancer deaths among women in Ethiopia. This may be due to the high prevalence of high-risk human papillomavirus (HR-HPV) genotypes in the population. So far, few studies have been done that showed the presence of HR-HPV genotypes. The HR-HPV-16, -18, -52, -56, -31 and -58 were the most common genotypes reported in Ethiopia. The introduction of HPV vaccines in Ethiopia is likely to go a long way in reducing cervical cancer deaths. However, there are few challenges to the introduction of the vaccines. The target population for HPV vaccination is at the moment not well-defined. Besides, the current HPV vaccines confer only type-specific (HPV-16 and -18) immunity, leaving a small proportion of Ethiopian women unprotected against other HR-HPV genotypes such as 52, 56, 31 and 58. Thus, future HPV vaccines such as the nanovalent vaccine may be more useful to Ethiopia as they will protect women against more genotypes.
