Multiple drought episodes over the Volta basin in recent reports may lead to food insecurity and loss of revenue. However, drought studies over the Volta basin are rather generalised and largely undocumented due to sparse ground observations and unsuitable framework to determine their space-time occurrence. In this study, we examined the utility of standardised indicators (standardised precipitation index (SPI), standardised runoff index (SRI), standardised soil moisture index (SSI), and multivariate standardised drought index (MSDI)) and Gravity Recovery and Climate Experiment (GRACE) derived terrestrial water storage to assess hydrological drought characteristics over the basin. In order to determine the space-time patterns of hydrological drought in the basin, Independent Component Analysis (ICA), a higher order statistical technique was employed. The results show that SPI and SRI exhibit inconsistent behaviour in observed wet years presupposing a non-linear relationship that reflects the slow response of river discharge to precipitation especially after a previous extreme dry period. While the SPI and SSI show a linear relationship with a correlation of 0.63, the correlation between the MSDIs derived from combining precipitation/river discharge and precipitation/soil moisture indicates a significant value of 0.70 and shows an improved skill in hydrological drought monitoring over the Volta basin during the study period. The ICA-derived spatio-temporal hydrological drought patterns show Burkina Faso and the Lake Volta areas as predominantly drought zones. Further, the statistically significant negative correlations of pacific decadal oscillations (0.39 and 0.25) with temporal evolutions of drought in Burkina Faso and Ghana suggest the possible influence of low frequency large scale oscillations in the observed wet and dry regimes over the basin. Finally, our approach in drought assessment over the Volta basin contributes to a broad framework for hydrological

The Lake Bosumtwi impact structure in Ghana: A brief environmental assessment and discussion of ecotourism potential

Science.gov (United States)

Boamah, Daniel; Koeberl, Christian

Lake Bosumtwi is a natural inland freshwater lake that originated from a meteorite impact. The lake is becoming a popular tourist attraction in Ghana and has the potential to be developed as an ecotourism site in the future. However, there have been some unregulated human activities and unplanned infrastructure development, and there are increased levels of pollutants in the lake water. In order to make ecotourism at Lake Bosumtwi successful in the long term, the Lake Bosumtwi Development Committee has been formed to ensure that local people are empowered to mobilize their own capacities. It has been realized that an important criterion required to develop ecotourism in a socially responsible, economically efficient, and environmentally viable way is to foster a constructive dialogue between the local people and tourists about the needs of the indigenous people.

The water quality examination at a section of the Lower Volta River (Akuse to the Sogakope area), Ghana, was conducted by determining the physicochemical parameters at 38 sampling sites in September (2011) during the wet season and February (2012) during the dry season. Isotope analysis was also conducted during the same period. The ranges of physicochemical parameters analysed in the surface water were 6.45 to 7.26 for pH, -053 to -010 mV for Eh, 23.6 to 27 degrees celsius for temperature, 61.7 to 83.6 μS/cm for EC, 0% 0 for salinity, 29.7-39.4 mg/L for TDS, 0.63 to 2.28 mg/L for DO, 0 to 4 NTU for turbidity, 0 to 8mg/L for TSS, 36 to 108mg/L for total hardness, 0.8 to 5mg/L for BOD 5 , 23.16 to 46.33mg/L for HCO 3 - , 2.92 to 23.33mg/L for Mg 2+ , 7.8 to 11.0mg/L for Na + , 4.0 to 5.9mg/L for K + , 1.99 to 13.99mg/L for CI - , 3.2 to 14.4MG/L for Ca 2+ , 1.0 to 24.889mg/L for NO 3 - , 6.556 to 28.111mg/L for SO 4 2- and 1.333 to 11.667mg/L for PO 4 3- . While the results for dissolved metals (μg/L) were 32 to 348 for Fe, 12 to 278 for Mn, 16 to 84 for Cu, 4 to 38 for Pb, 20 to 162 for Ni, 12 to 32 for Cd and 12μg/L to 98 for Cd, Hg, Se, V and Zn were below detection limit. The river water will support agricultural activities. Except Cu which was low, about 37%, 89%, 29%, 33%, 8% and 29% of the sampled sites had Pb, Ni, Cd, Cr, Fe and Mn values respectively above the WHO (2004) standard for drinking water. Therefore, water quality monitoring and control of release of untreated anthropogenic wastes into the river is strongly needed. Stable isotope data of water (δ 2 H and δ 18 O) obtained showed stream waters are depleted and possibly recharge by rain and waters from the Akwapim Mountains than the isotopically heavy evaporated waters found within the Lower Volta River.

2006-01-01

The coupling effect of vapour release and CO2 uptake during photosynthesis plays an important role in the carbon and hydrologic cycles. The water use efficiency (WUE) for transpiration was used in calculating the net primary productivity (NPP) for terrestrial ecosystem. Three parameters were used in calculating the water and carbon balance of the River Volta watershed. These are 1) stable isotopes of hydrogen and oxygen, 2) long-term data on precipitation and evapotranspiration, and 3) stoichiometric relations of water and carbon. Results indicate that soils in the watershed annually respire 0.199 Pg C, and that the NPP is +0.029 Pg C yr-1. This implies an annual change in CO2 to the atmosphere within the watershed. Annually, River Volta watershed receives about 380 km3 of rainfall; approximately 50 per cent of which is returned to the atmosphere through plant transpiration. Associated with annual transpiration flux is a carbon flux of 0.170 x 1015 g C yr-1 or 428 g C m-2 yr-1 from the terrestrial ecosystem. Modeled estimates of heterotrophic soil respiration exceeds slightly the estimated NPP values, implying that carbon flux to and from the Volta river watershed is close to being in balance. In other words, the watershed releases annually more carbon dioxide to the atmosphere than it takes. Apart from the terrestrial carbon flux, the balance of photosynthesis and respiration in the Volta lake was also examined. The lake was found to release carbon dioxide to the atmosphere although the magnitude of the flux is smaller than that of the terrestrial ecosystem. (au)

Full Text Available Abstract Background Coverage of vulnerable groups with insecticide-treated nets (ITNs in Ghana, as in the majority of countries of sub-Saharan Africa is currently low. A voucher scheme was introduced in Volta Region as a possible sustainable delivery system for increasing this coverage through scale-up to other regions. Successful scale-up of public health interventions depends upon optimal delivery processes but operational research for delivery processes in large-scale implementation has been inadequate. Methods A simple tool was developed to monitor numbers of vouchers given to each health facility, numbers issued to pregnant women by the health staff, and numbers redeemed by the distributors back to the management agent. Three rounds of interviews were undertaken with health facility staff, retailers and pregnant women who had attended antenatal clinic (ANC. Results During the one year pilot 25,926 vouchers were issued to eligible women from clinics, which equates to 50.7% of the 51,658 ANC registrants during this time period. Of the vouchers issued 66.7% were redeemed by distributors back to the management agent. Initially, non-issuing of vouchers to pregnant women was mainly due to eligibility criteria imposed by the midwives; later in the year it was due to decisions of the pregnant women, and supply constraints. These in turn were heavily influenced by factors external to the programme: current household ownership of nets, competing ITN delivery strategies, and competition for the limited number of ITNs available in the country from major urban areas of other regions. Conclusion Both issuing and redemption of vouchers should be monitored as factors assumed to influence voucher redemption had an influence on issuing, and vice versa. More evidence is needed on how specific contextual factors influence the success of voucher schemes and other models of delivery of ITNs. Such an evidence base will facilitate optimal strategic decision making

Hydrochemical analysis of groundwater using multivariate statistical methods - The Volta region, Ghana

Q and R-mode multivariate statistical analyses were applied to groundwater chemical data from boreholes and wells in the northern section of the Volta region Ghana. The objective was to determine the processes that affect the hydrochemistry and the variation of these processes in space among the three main geological terrains: the Buem formation, Voltaian System and the Togo series that underlie the area. The analyses revealed three zones in the groundwater flow system: recharge, intermediate and discharge regions. All three zones are clearly different with respect to all the major chemical parameters, with concentrations increasing from the perceived recharge areas through the intermediate regions to the discharge areas. R-mode HCA and factor analysis (using varimax rotation and Kaiser Criterion) were then applied to determine the significant sources of variation in the hydrochemistry. This study finds that groundwater hydrochemistry in the area is controlled by the weathering of silicate and carbonate minerals, as well as the chemistry of infiltrating precipitation. This study finds that the ??D and ??18O data from the area fall along the Global Meteoric Water Line (GMWL). An equation of regression derived for the relationship between ??D and ??18O bears very close semblance to the equation which describes the GMWL. On the basis of this, groundwater in the study area is probably meteoric and fresh. The apparently low salinities and sodicities of the groundwater seem to support this interpretation. The suitability of groundwater for domestic and irrigation purposes is related to its source, which determines its constitution. A plot of the sodium adsorption ratio (SAR) and salinity (EC) data on a semilog axis, suggests that groundwater serves good irrigation quality in the area. Sixty percent (60%), 20% and 20% of the 67 data points used in this study fall within the medium salinity - low sodicity (C2-S1), low salinity -low sodicity (C1-S1) and high salinity - low

Adolescents and parents' differ in their perceptions regarding engaging in sexual activity and protecting themselves from pregnancy and sexually transmitted infections (STIs). The views of adolescents and parents from two south-eastern communities in Ghana regarding best time for sex and sexual communications were examined. Focus Group interviews were conducted with parents and adolescents (both In-school and Out-of school) from two communities (Somanya and Adidome) in the Eastern and Volta regions of Ghana with epidemiological differentials in HIV infection. Findings showed parents and adolescents agree that the best timing for sexual activity amongst adolescents is determined by socioeconomic viability. In practice however, there were tensions between adolescents and parents crystallized by spoilt generation and physiological drive ideologies. Whilst one community relied on a more communal approach in controlling their children; the other relied on a confrontational approach. Sex-talk is examined as a measure to reduce these tensions, and children in both communities were ambivalent over sexual communication between their parents and themselves. Parents from the two communities however differed in their perceptions. Whilst parents in one community attributed reduced teenage pregnancies to sex education, those in the other community indicated a generalized adolescents' sexual activeness manifested in the perceived widespread delinquency in the community. Parents in both communities reported significant barriers to parents-adolescents sexual communication. Parents in both communities should be educated to discuss the broader issues on sexuality that affects adolescents and their reproductive health needs.

Predicting the downstream impact of ensembles of small reservoirs with special reference to the Volta Basin, West Africa

Science.gov (United States)

van de Giesen, N.; Andreini, M.; Liebe, J.; Steenhuis, T.; Huber-Lee, A.

2005-12-01

After a strong reduction in investments in water infrastructure in Sub-Saharan Africa, we now see a revival and increased interest to start water-related projects. The global political willingness to work towards the UN millennium goals are an important driver behind this recent development. Large scale irrigation projects, such as were constructed at tremendous costs in the 1970's and early 1980's, are no longer seen as the way forward. Instead, the construction of a large number of small, village-level irrigation schemes is thought to be a more effective way to improve food production. Such small schemes would fit better in existing and functioning governance structures. An important question now becomes what the cumulative (downstream) impact is of a large number of small irrigation projects, especially when they threaten to deplete transboundary water resources. The Volta Basin in West Africa is a transboundary river catchment, divided over six countries. Of these six countries, upstream Burkina Faso and downstream Ghana are the most important and cover 43% and 42% of the basin, respectively. In Burkina Faso (and also North Ghana), small reservoirs and associated irrigation schemes are already an important means to improve the livelihoods of the rural population. In fact, over two thousand such schemes have already been constructed in Burkina Faso and further construction is to be expected in the light of the UN millennium goals. The cumulative impact of these schemes would affect the Akosombo Reservoir, one of the largest manmade lakes in the world and an important motor behind the economic development in (South) Ghana. This presentation will put forward an analytical framework that allows for the impact assessment of (large) ensembles of small reservoirs. It will be shown that despite their relatively low water use efficiencies, the overall impact remains low compared to the impact of large dams. The tools developed can be used in similar settings elsewhere

Organochlorine pesticides in fish, water and sediments in the middle Volta Basin: a case study of Kpando Torkor lake, Volta Region of Ghana

The levels of contamination with selected organochlorine pesticides (OCPs) in water, sediment, and two commonly harvested fish species namely Tilapia zilli and Chrysichthys nigrodigitatus from Kpando Torkor Lake were determined. This was to give the general picture of the extent of contamination of these matrices with OCPs and also assess the suitability of the water and fish catch for human consumption. Organochlorine pesticides residues in water samples were extracted using liquid-liquid extraction whilst Soxhlet was used in the case of fish and sediment samples. All extracts were cleaned-up using packed columns and then analyzed using Gas chromatography equipped with 63 Ni electron-capture detector (ECD). Fifteen organochlorine pesticide residues namely β-HCH, γ-HCH, δ-HCH, p,p'-DDT, p,p'-DDD, p,p'-DDE, Heptachlor, Aldrin, Dieldrin, Endrin, γ-Chlordane, α-Endosulfan, β-Endosulfan, Endosulfan sulphate and Methoxychlor were investigated in this study. Thirteen of them excluding γ-HCH and Endrin were detected in sediment and fish samples at concentrations ranging from below the level of quantification (LOQ) to 37.75ng/g wet weight, and occurrence frequencies ranging from 14 to 100%. Twelve of them excluding p,p'-DDT, -HCH and Endrin were however, measured in water samples with concentrations ranging from below LOQ to 0.669μg/L and occurrence frequencies ranging from 14 to 29%. γ-HCH and p,p'-DDD were the most frequently detected residues in all samples analyzed with an average percentage frequency of 85.8, followed by Endosulfan sulphate (83.0%) and β-HCH (80.0%) among others. In consonance with their properties, organochlorine pesticide residues measured in fish samples were higher than those of sediment samples. Even though, the fat content of catfish muscle (10.24%) was higher than tilapia muscle (2.80%), the levels of organochlorine pesticide residues in tilapia tissues were however, higher than that of catfish. For instance, the levels of β-HCH in

Moore, P.; Williams, S. D. P.

2014-12-01

Terrestrial water storage (TWS) change for 2003-2011 is estimated over Africa from GRACE gravimetric data. The signatures from change in water of the major lakes are removed by utilizing kernel functions with lake heights recovered from retracked ENVISAT satellite altimetry. In addition, the contribution of gravimetric change due to soil moisture and biomass is removed from the total GRACE signal by utilizing the GLDAS land surface model. The residual TWS time series, namely groundwater and the surface waters in rivers, wetlands, and small lakes, are investigated for trends and the seasonal cycle using linear regression. Typically, such analyses assume that the data are temporally uncorrelated but this has been shown to lead to erroneous inferences in related studies concerning the linear rate and acceleration. In this study, we utilize autocorrelation and investigate the appropriate stochastic model. The results show the proper distribution of TWS change and identify the spatial distribution of significant rates and accelerations. The effect of surface water in the major lakes is shown to contribute significantly to the trend and seasonal variation in TWS in the lake basin. Lake Volta, a managed reservoir in Ghana, is seen to have a contribution to the linear trend that is a factor of three greater than that of Lake Victoria despite having a surface area one-eighth of that of Lake Victoria. Analysis also shows the confidence levels of the deterministic trend and acceleration identifying areas where the signatures are most likely due to a physical deterministic cause and not simply stochastic variations.

Changes in the fish community of the Kpong Headpond, lower Volta River, Ghana after 25 years of impoundment

Full Text Available The Kpong Headpond was the second created on the Volta River after Akosombo Dam, primarily as a source of hydroelectric power generation and potable water supply, and additionally, it has supported some fish production in Ghana since impoundment. The changes in fish community of the Kpong Headpond were studied to provide baseline information for strategies formulation to support the socio-economic development of the reservoir. The study identified changes in the fish community of the reservoir by comparing occurrence, composition, relative abundance and relative importance estimates of fish species, families and trophic groups, from available previous studies in the reservoir. From the collated information all fishes identified in the reservoir were categorised based on occurrence and importance as disappeared, appeared, permanent, declined or important, to show current status. The results indicated that the fish community has experienced a shift in the composition and relative abundance of important species, families and trophic groups in terms of number and weight, while remaining ecologically balanced. Representatives of the families Osteoglossidae, Centropomidae and Characidae have declined while representatives of the families Claroteidae, Cyprinidae and Cichlidae have increased. The aufwuch-detritus and herbivores declined while semi-pelagic omnivores increased resulting in a shift in dominance to benthic and semi pelagic omnivores. The appearance of five species and the disappearance of 25 others indicated a dynamic restructuring of the fish community in the reservoir, as expected. Enforcement of fishing regulations including the use of appropriate gear and fishing methods, fishery access control, promotion of culture-based fisheries and improvement in fisher education are recommended topics for sustainable fisheries in the reservoir.

Full Text Available The Cape Saint Paul Wilt Disease (CSPWD, a lethal-yellowing type disease of coconut has been in Ghana since 1932. Aerial and/or ground surveys were undertaken to assess the current status of the disease spread. The survey showed that the spread of the disease for the past 5 years has mainly been the expansion of existing foci. However, new outbreaks were identified at Glidzi in the Volta, Bawjiase and Efutu Breman in Central regions. After the resurgence in the Volta region in 1995, the Woe-Tegbi-Dzelukope corridor has remained endemic, but less aggressive. Pockets of healthy groves remain along all the coastline and inland of known disease zones. Eradication of diseased palms at Ampain focus lying just about 60 km to the Ivorian border, and disease situations on new replanting with MYD × VTT hybrid are discussed.

Radon measurements in Ghana: health risk assesment at the Lake Bosomtwi basin

The need to assess the risk of exposure to radon and its daughters stems from the reality, that radon is a potential carcinogenic. We report Radon-222 risk assessment, from measurements on soil and sediments taken from six towns along the Lake Bosomtwi basin at two levels of 10cm and 20cm. The current and future prospects of Lake Bosomtwi, the largest natural lake in Ghana, make this assessment imperative, since radon forms half of natural background radiation. Spatial Analyser Decision Assistant (SADA) algorithms were used to model the measured radon concentrations under two land-use scenarios, namely residential and recreational. Setting the data under a targeted risk of 1E-6,we found that the external exposure was below that of the maximum concentrations to the measurements. This indicates that the radon levels around those towns as of the time of the measurements is low and below limits which can cause carcinogenic threats. The mean risk associated with the sampled locations was found to be 9E-11 at the recreational areas and 2E-8 at residential centres. To confirm the authenticity of the point risk analysis, geospatial modelling based on inverse distance interpolation schemes were performed. The results tally closely with that of the measured point risk analysis with and error margin of 2% and 1.3 % for both land use scenarios at 10 cm and 20 cm depth respectively. (au)

Exposure levels, environmental fate modelling and human health risk assessment of lindane in Ghana

International Nuclear Information System (INIS)

Adu-Kumi, S.

2011-01-01

�-HCH which is a known environmental estrogen, was predominant contaminant measured (geometric mean concentrations 4.18 ng g -1 lipid wt. and 4.35 ng g -1 lipid wt. for pooled and individual samples respectively). The levels of Lindane, α-HCH and β-HCH in edible fish (catfish and tilapia) sourced from Lake Bosumtwi and the Weija Lake, were concurrently investigated using HRGC/HRMS. Concentrations of HCHs were found to be generally low (mainly limits of detection) probably reflecting the historical use of Lindane and technical HCH mixtures. Catfish sourced from Lake Volta (purchased from the Madina market) however contained appreciable amounts of Lindane (average concentration of 0.72 ng g -1 lipid wt). Measured values are lower than the maximum acceptable limit for human consumption established by the FAO/WHO (FAO/WHO, 1986). Hence there is no potential health risk from HCHs (Lindane, α-HCH and β-HCH) in fish for the general population of Ghana. Level III and level IV fugacity models were successfully applied to investigate the environmental fate of Lindane in the compartments of air, water, sediment, soil and biota (fish). Model estimates showed that air, water, soil and fish constitute important exposure pathways of Lindane for the general population of Ghana. The estimated total amount of Lindane accumulated in all media at steady-state was 136 tonnes, the soil compartment accounting for ore than 97% of the total accumulation. Time trends in concentration and fluxes simulated in for the period 1959-2020 predicted that less than 1% of the 2002 concentration levels of Lindane in air, water and soil, respectively, will be left in 2020. Finally, health risks associated with the exposure of the general population of Ghana to Lindane via the pathways of air, water, soil, food (or diet) were characterized using the combined field measurements and results of the multi-media environmental fate modelling. Diet (mainly vegetables), soil and to a lesser extent water constituted

"He will ask why the child gets sick so often": the gendered dynamics of intra-household bargaining over healthcare for children with fever in the Volta Region of Ghana.

This paper explores the gendered dynamics of intra-household bargaining around treatment seeking for children with fever revealed through two qualitative research studies in the Volta Region of Ghana, and discusses the influence of different gender and health discourses on the likely policy implications drawn from such findings. Methods used included focus group discussions, in-depth and critical incidence interviews, and Participatory Learning and Action methods. We found that treatment seeking behaviour for children was influenced by norms of decision-making power and 'ownership' of children, access to and control over resources to pay for treatment, norms of responsibility for payment, marital status, household living arrangements, and the quality of relationships between mothers, fathers and elders. However, the implications of these findings may be interpreted from different perspectives. Most studies that have considered gender in relation to malaria have done so within a narrow biomedical approach to health that focuses only on the outcomes of gender relations in terms of the (non-)utilisation of allopathic healthcare. However, we argue that a 'gender transformatory' approach, which aims to promote women's empowerment, needs to include but go beyond this model, to consider broader potential outcomes of intra-household bargaining for women's and men's interests, including their livelihoods and 'bargaining positions'.

Full Text Available Although a number of studies have been conducted to explore the effect of water quality improvement, the majority of them have focused mainly on point-of-use water treatment, and the studies investigating the effect of improved water supply have been based on observational or inadequately randomized trials. We report the results of a matched cluster randomized trial investigating the effect of improved water supply on diarrheal prevalence of children under five living in rural areas of the Volta Region in Ghana. We compared the diarrheal prevalence of 305 children in 10 communities of intervention with 302 children in 10 matched communities with no intervention (October 2012 to February 2014. A modified Poisson regression was used to estimate the prevalence ratio. An intention-to-treat analysis was undertaken. The crude prevalence ratio of diarrhea in the intervention compared with the control communities was 0.85 (95% CI 0.74–0.97 for Krachi West, 0.96 (0.87–1.05 for Krachi East, and 0.91 (0.83–0.98 for both districts. Sanitation was adjusted for in the model to remove the bias due to residual imbalance since it was not balanced even after randomization. The adjusted prevalence ratio was 0.82 (95% CI 0.71–0.96 for Krachi West, 0.95 (0.86–1.04 for Krachi East, and 0.89 (0.82–0.97 for both districts. This study provides a basis for a better approach to water quality interventions.

Simulium damnosum s.l., the most important vector of onchocerciasis in Africa, is a complex of sibling species that have been described on the basis of differences in their larval polytene chromosomes. These (cyto) species differ in their geographical distributions, ecologies and epidemiological roles. In Ghana, distributional changes have been recorded as a consequence of vector control and environmental change (e.g. deforestation), with potential disease consequences. We review the distribution of cytospecies in southern Ghana and report changes observed with reference to historical data collated from 1971 to 2005 and new identifications made between 2006 and 2011. Larvae were collected from riverine breeding sites, fixed in Carnoy's solution and chromosome preparations made. Cytotaxonomic identifications from 1,232 samples (including 49 new samples) were analysed. We report long-term stability in cytospecies distribution in the rivers Afram, Akrum, Pawnpawn and Pru. For the rivers Oda, Ofin and Tano we describe (for the first time) patterns of distribution. We could not detect cytospecies composition changes in the upper Pra, and the lower Pra seems to have been stable. The elimination of the Djodji form of S. sanctipauli in the Volta Region seems to have had no long-term effects on the distribution of the other cytospecies, despite an initial surge by S. yahense. There has been a recent increase in the occurrence of savannah cytospecies in the river Asukawkaw, and this might be related to continuing deforestation. Cytospecies' distributions have not been stable from 1971 to 2011. Although there are no obvious causes for the temporary appearance and subsequent disappearance of cytospecies in a particular location, a major influence has been vector control and migration patterns, probably explaining observed changes on the Black Volta and lower Volta rivers. Deforestation was previously implicated in an increase of savannah cytospecies in southern Ghana (1975

Yeleliere, E.; Cobbina, S. J.; Duwiejuah, A. B.

2018-06-01

Freshwater resources are continually decreasing in quality and quantity. Approximately, 1% of this freshwater is accessible in lakes, river channels and underground for domestic use. The study reviewed literature on water resources with focus on freshwater, the quality of our freshwater in terms of physical, chemical and biological variables, the main mechanisms of management, and the challenges associated with these mechanisms as well as blending integrated water management with the indigenous or traditional management of water resources for sustainable development and peaceful co-existence. Also the review offered potent recommendations for policy makers to consider sustainable management of freshwater resources. A total of 95 articles were downloaded from Google scholar in water-related issues. The search took place from June to September 2017, and research articles from 1998 to 2018 were reviewed. Basically Ghana is made up of three discharge or outlet systems, namely the Coastal River Systems which is the least and Volta constituting the largest and with the South-Western been the intermediate. Also, freshwater resources usage can be put into two main categories, namely ex situ (withdrawal use) and in situ or in-stream use, and could also be referred to as the consumptive and non-consumptive use, respectively. With the exception of localised pollution engineered by illegal mining and other nuisance perpetuated by indigenes, the quality of water (surface and groundwater) in Ghana is generally better. The review outlined high microbial contamination of water as almost all surface waters are contaminated with either E. coli, faecal coliforms or total coliforms or all. However, these contaminations were more prevalent in surface water than groundwater.

Scenario of the emerging shift from gasoline to LPG fuelled cars in Ghana: A case study in Ho Municipality, Volta Region

International Nuclear Information System (INIS)

Biscoff, Robert; Akple, Maxwell; Turkson, Richard; Klomegah, Wise

2012-01-01

The use of LPG as automotive fuel is on the increase worldwide. In developing countries such as Ghana, the rudimental way of operating LPG cars is of a national concern since there is no clear cut framework within which they function. This paper presents a scenario of development from conversion of gasoline to LPG fuelling system in cars in Ho, Ghana. Data were collected through survey (100 questionnaires), in-depth interviews (2), Focus Group Discussions (3) and direct observations. The result shows LPG conversion is carried out by the local informally trained mechanics especially for Taxis because of its low consumption resulting in more profit. Conversion takes 1–2 day with an average estimated cost of GH□ 450 cedis ($300). The LPG policy in Ghana focuses on domestic purposes hence the fuel being heavily subsidised. Challenges' being faced by the autogas market in Ghana includes; no clear cut policy, low number of refuelling stations, lack of standard conversion and installation kits and unprofessional LPG installers. In order for government to benefit from LPG as automotive fuel, coherent autogas policy should be formulated ensuring the availability of the LPG with price affordability as in the case of gasoline and diesel. - Highlights: ► Cars are converted to LPG system locally because of economic gains relative to emission reduction. ► LPG fuelled cars makes twice profit as compared to gasoline cars. ► Conversion to LPG system takes 1–2 day with an average cost of GH 450 cedis ($300). ► LPG policy in Ghana focus on domestic purposes not for commercial hence heavily subsidised. ► Ghana Government should formulate clear policy on LPG use in cars.

Application of Volta potential mapping to determine metal surface defects

International Nuclear Information System (INIS)

Nazarov, A.; Thierry, D.

2007-01-01

As a rule, stress or fatigue cracks originate from various surface imperfections, such as pits, inclusions or locations showing a residual stress. It would be very helpful for material selection to be able to predict the likelihood of environment-assisted cracking or pitting corrosion. By using Scanning Kelvin Probe (the vibrating capacitor with a spatial resolution of 80 μm) the profiling of metal electron work function (Volta potential) in air is applied to the metal surfaces showing residual stress, MnS inclusions and wearing. The Volta potential is influenced by the energy of electrons at the Fermi level and drops generally across the metal/oxide/air interfaces. Inclusions (e.g. MnS) impair continuity of the passive film that locally decreases Volta potential. The stress applied gives rise to dislocations, microcracks and vacancies in the metal and the surface oxide. The defects decrease Volta and corrosion potentials; reduce the overvoltage for processes of passivity breakdown and anodic metal dissolution. These 'anodic' defects can be visualized in potential mapping that can help us to predict locations with higher risk of pitting corrosion or cracking

Biophysical and Socioeconomic State and Links of Deltaic Areas Vulnerable to Climate Change: Volta (Ghana, Mahanadi (India and Ganges-Brahmaputra-Meghna (India and Bangladesh

Full Text Available We examine the similarities and differences of specific deltaic areas in parallel, under the project DEltas, vulnerability and Climate Change: Migration and Adaptation (DECCMA. The main reason for studying Deltas is their potential vulnerability to climate change and sea level rise, which generates important challenges for livelihoods. We provide insights into the current socioeconomic and biophysical states of the Volta Delta (Ghana, Mahanadi Delta (India and Ganges-Brahmaputra-Meghna (India and Bangladesh. Hybrid methods of input-output (IO construction are used to develop environmentally extended IO models for comparing the economic characteristics of these delta regions with the rest of the country. The main sources of data for regionalization were country level census data, statistics and economic surveys and data on consumption, trade, agricultural production and fishing harvests. The Leontief demand-driven model is used to analyze land use in the agricultural sector of the Delta and to track the links with final demand. In addition, the Hypothetical Extraction Method is used to evaluate the importance of the hypothetical disappearance of a sector (e.g., agriculture. The results show that, in the case of the Indian deltas, more than 60% of the cropland and pasture land is devoted to satisfying demands from regions outside the delta. While in the case of the Bangladeshi and Ghanaian deltas, close to 70% of the area harvested is linked to internal demand. The results also indicate that the services, trade and transportation sectors represent 50% of the GDP in the deltas. Still, agriculture, an activity directly exposed to climate change, plays a relevant role in the deltas’ economies—we have estimated that the complete disappearance of this activity would entail GDP losses ranging from 18 to 32%.

Risk assessment of radon in the South Dayi District of the Volta Region, Ghana

Directory of Open Access Journals (Sweden)

Charles Y. Ansre

2018-01-01

Full Text Available Radon is a globally present and known radioactive gas with its ability to cause lung cancer as its major health implication. Ghana currently lacks national policies on radon gas and substantive radon vulnerability map largely due to lack of adequate baseline radon concentration data for the entire country. LR115 type II detectors were deployed in 30 sites/homes within the South-Dayi District. The detectors were retrieved after specified periods and analyzed for the radon concentration at the Nuclear Track Detection Laboratory of the Ghana Atomic Energy Commission. From the results, indoor radon concentration was found to range from 11.60 to 111.07 Bq/m3 with the mean value for the district being 34.90 ± 20.18 Bq/m3, a value lower than the mean global indoor concentration of 40 Bq/m3. The values of 0.44 mS/yr, 8.80 mSv/yr and 1.01 mSv/yr were the mean annual; absorbed dose, equivalent dose and effective dose to lungs respectively for the populace of the district. The mean soil radon concentration for the district was 1.76 ± 0.91 kBq/m3 with values ranging from 0.38 to 3.93 kBq/m3. Correlation and T-test analysis was performed to establish strength of the linear relationship between indoor radon concentration and the soil radon concentration, indoor radon concentration on altitude and soil radon concentration on altitude.

This study explores the techno-economic potential of rice residues as a bioenergy resource to meet Ghana's energy demands. Major rice growing regions of Ghana have 70-90% of residues available for bioenergy production. To ensure cost-effective biomass logistics, a thorough cost analysis was made for two bioenergy routes. Logistics costs for a 5 MWe straw combustion plant were 39.01, 47.52 and 47.89 USD/t for Northern, Ashanti and Volta regions respectively. Logistics cost for a 0.25 MWe husk gasification plant (with roundtrip distance 10 km) was 2.64 USD/t in all regions. Capital cost (66-72%) contributes significantly to total logistics costs of straw, however for husk logistics, staff (40%) and operation and maintenance costs (46%) dominate. Baling is the major processing logistic cost for straw, contributing to 46-48% of total costs. Scale of straw unit does not have a large impact on logistic costs. Transport distance of husks has considerable impact on logistic costs. Copyright © 2014 Elsevier Ltd. All rights reserved.

coast and responding to erosion issues. Funding for program development and equipment has been provided via the Coastal Geosciences Program of the U.S. Office of Naval Research through the Navy’s Africa Partnership Station. Data collection and analysis to date include the first regional shoreline change assessment of the Ghana coast, utilizing aerial photography spanning 31 years and RTK-GPS field surveys and reconnaissance mapping. Initial results from the shoreline change analysis indicate highly variable alongshore rates of change, although the trend is predominantly erosional. The highest erosion rates are found in the east, on the downdrift flank of the low-lying, sandy Volta Delta complex. The rapid erosion rates are likely due to the disruption of sediment supplied to the coast by the damming of the Volta River in the 1960s, as well as alongshore transport gradients generated by the progradation and morphologic evolution of the delta. Continuing investigations of coastal processes in Ghana will allow for a better understanding of erosion hazards and will aid in the development of appropriate, systematic, and sustainable responses to future increased hazards associated with rising sea-levels.

Volta concluded that electricity was an artificial and external phenomenon, dependent on the metals and unrelated with the frog’s body; Galvani concluded that the frog’s movement proved that there was such a thing as animal electricity that, even after life, remained stored in nerves a...

The impact of pesticides use on surface water and groundwater: a case study in the Kadjebi District, Volta Region, Ghana

International Nuclear Information System (INIS)

Suraj, S. I.

2015-07-01

The Kadjebi district is predominantly made up of farming communities, hence, the major economic activities in the area are the cultivation of cocoa, ginger, maize, vegetables. The extensive use of organochlorines, organophosphate and synthetic pyrethroids have raised concerns about potential adverse effect on human health and the environment. This study aims at assessing the impact of pesticide use on surface water and groundwater in the Kadjebi District of the Volta Region of Ghana. Results of the study revealed that about 92.6% of farmers used one or more pesticides obtained from agro-chemical shops, Cocoa Marketing Board, cooperative societies and relatives in labelled and unlabeled containers. Of these numbers, 62% admitted not having access to services of the extension officers on the use and application of pesticides, hence, believe that, the more the chemical applied the faster and better the result. 18% of the farmers reported positively to the use of protective gears to cover the whole body during pesticide application, 12% cover only the face while 45% do not use any protective gear. On the disposal of the pesticide containers, 51% indicated that, they re-use the containers for food and water storage after thoroughly washing with soap and water. The data obtained also showed a high risk of pesticide poisoning and occupational exposure, about 68% of the respondents reported clinical symptoms of pesticide poisoning such as nausea, headache, blurred vision, eye irritation, dizziness, vomiting and skin irritation. About 51% of water samples analyzed showed positive detections of pesticide residues while all sediments samples showed positive detections of pesticides residues varying from one to five different types of pesticides residues. The common pesticides residues found in the samples were Deltamethrine, Cyfluthrin, Cypermethrin, Dieldrin, Fenvaerate, Lambda-cyhal, p,p’ DDT. Synthetic pyrethroids (72%) were the dominant residues detected. Deltamethrine

Transduction-like gene transfer in the methanogen Methanococcus voltae

Science.gov (United States)

Bertani, G.

1999-01-01

Strain PS of Methanococcus voltae (a methanogenic, anaerobic archaebacterium) was shown to generate spontaneously 4.4-kbp chromosomal DNA fragments that are fully protected from DNase and that, upon contact with a cell, transform it genetically. This activity, here called VTA (voltae transfer agent), affects all markers tested: three different auxotrophies (histidine, purine, and cobalamin) and resistance to BES (2-bromoethanesulfonate, an inhibitor of methanogenesis). VTA was most effectively prepared by culture filtration. This process disrupted a fraction of the M. voltae cells (which have only an S-layer covering their cytoplasmic membrane). VTA was rapidly inactivated upon storage. VTA particles were present in cultures at concentrations of approximately two per cell. Gene transfer activity varied from a minimum of 2 x 10(-5) (BES resistance) to a maximum of 10(-3) (histidine independence) per donor cell. Very little VTA was found free in culture supernatants. The phenomenon is functionally similar to generalized transduction, but there is no evidence, for the time being, of intrinsically viral (i.e., containing a complete viral genome) particles. Consideration of VTA DNA size makes the existence of such viral particles unlikely. If they exist, they must be relatively few in number;perhaps they differ from VTA particles in size and other properties and thus escaped detection. Digestion of VTA DNA with the AluI restriction enzyme suggests that it is a random sample of the bacterial DNA, except for a 0.9-kbp sequence which is amplified relative to the rest of the bacterial chromosome. A VTA-sized DNA fraction was demonstrated in a few other isolates of M. voltae.

Ghana has developed two main community-based strategies that aim to increase access to quality treatment for malaria, diarrhoea and suspected pneumonia: the integrated community case management (iCCM) and the community-based health planning and services (CHPS). The aim of the study was to assess the cost-effectiveness of these strategies under programme conditions. A cost-effectiveness analysis was conducted. Appropriate diagnosis and treatment given was the effectiveness measure used. Appropriate diagnosis and treatment data was obtained from a household survey conducted 2 and 8 years after implementation of iCCM in the Volta and Northern Regions of Ghana, respectively. The study population was carers of children under-5 years who had fever, diarrhoea and/or cough in the last 2 weeks prior to the interview. Costs data was obtained mainly from the National Malaria Control Programme (NMCP), the Ministry of Health, CHPS compounds and from a household survey. Appropriate diagnosis and treatment of malaria, diarrhoea and suspected pneumonia was more cost-effective under the iCCM than under CHPS in the Volta Region, even after adjusting for different discount rates, facility costs and iCCM and CHPS utilization, but not when iCCM appropriate treatment was reduced by 50%. Due to low numbers of carers visiting a CBA in the Northern Region it was not possible to conduct a cost-effectiveness analysis in this region. However, the cost analysis showed that iCCM in the Northern Region had higher cost per malaria, diarrhoea and suspected pneumonia case diagnosed and treated when compared to the Volta Region and to the CHPS strategy in the Northern Region. Integrated community case management was more cost-effective than CHPS for the treatment of malaria, diarrhoea and suspected pneumonia when utilized by carers of children under-5 years in the Volta Region. A revision of the iCCM strategy in the Northern Region is needed to improve its cost-effectiveness. Long-term financing

Comparing and contrasting observed adaptations in three deltas: the Ganges-Meghna-Brahmaputra, Mahanadi and Volta

In low and middle-income countries, many deltaic communities directly depend on the natural environment for income and well-being. Current environmental concerns that threaten deltaic communities, such as increasing salinity, sedimentation, erosion and subsidence are likely to be exacerbated by climate change and variability, for example sea-level rise, increased storminess and rising temperatures. Such changes, along with other social and environmental stressors, mean that communities must adapt. This paper outlines findings of a systematic review of the peer-reviewed and grey literature that examines observed adaptations in three deltas of differing sizes in various geographical contexts: the Ganges-Meghna-Brahmaputra in India and Bangladesh, the Mahanadi in India, and the Volta in Ghana. It compares and contrasts various elements of observed adaptations, including who is driving the adaptation, the beneficiaries, barriers to participation and evidence for maladaptation. The predominant drivers of adaptation vary from government (at state level in India and national level in Bangladesh) and NGOs (in Ghana). Autonomous adaptations are not widely reported in the literature from any of the deltas. In all three deltas there is a focus on supporting adaptation in farming rather than fishing; despite the fact that fisheries contribute to local food security as well as national economies. Lack of access to financial, natural, physical and human capital are common barriers to adaptation in all three deltas. Additionally the Indian literature in particular highlights the lack of coordination between different government departments, coupled with an excessively top-down (state-driven) approach to adaptation. Maladaptation is most commonly reported in the literature from Bangladesh, for example, loss of employment of inland fishermen in embanked areas. The paper concludes by highlighting some of the implications of these findings for adaptation policy in deltas.

Water Accounting Plus for sustainable water management in the Volta river basin, West Africa

Dembélé, Moctar; Schaefli, Bettina; Mariéthoz, Grégroire; Ceperley, Natalie; Zwart, Sander J.

2017-04-01

Water Accounting Plus (WA+) is a standard framework that provides estimates of manageable and unmanageable water flows, stocks, consumption among users, and interactions with land use. The water balance terms are estimated based on remotely sensed data from online open access databases. The main difference with other methods is the use of spatiotemporal data, limiting the errors due to the use of static data. So far, no studies have incorporated climate change scenarios in the WA+ framework to assess future water resources, which would be desirable for developing mitigation and adaptation policies. Moreover WA+ has been implemented using remote sensing data while hydrological models data can also be used as inputs for projections on the future water accounts. This study aims to address the above challenges by providing quantified information on the current and projected state of the Volta basin water resources through the WA+ framework. The transboundary Volta basin in West Africa is vulnerable to floods and droughts that damage properties and take lives. Residents are dependent on subsistence agriculture, mainly rainfed, which is sensitive to changes and variation in the climate. Spatially, rainfall shows high spatiotemporal variability with a south-north gradient of increasing aridity. As in many basins in semi-arid environments, most of the rainfall in the Volta basin returns to the atmosphere. The competition for scarce water resources will increase in the near future due to the combined effects of urbanization, economic development, and rapid population growth. Moreover, upstream and downstream countries do not agree on their national priorities regarding the use of water and this brings tensions among them. Burkina Faso increasingly builds small and medium reservoirs for small-scale irrigation, while Ghana seeks to increase electricity production. Information on current and future water resources and uses is thus fundamental for water actors. The adopted

Full Text Available The effects of temperature and rainfall changes on hydropower generation in Ghana from 1960–2011 were examined to understand country-wide trends of climate variability. Moreover, the discharge and the water level trends for the Akosombo reservoir from 1965–2014 were examined using the Mann-Kendall test statistic to assess localised changes. The annual temperature trend was positive while rainfall showed both negative and positive trends in different parts of the country. However, these trends were not statistically significant in the study regions in 1960 to 2011. Rainfall was not evenly distributed throughout the years, with the highest rainfall recorded between 1960 and 1970 and the lowest rainfalls between 2000 and 2011. The Mann-Kendall test shows an upward trend for the discharge of the Akosombo reservoir and a downward trend for the water level. However, the discharge irregularities of the reservoir do not necessarily affect the energy generated from the Akosombo plant, but rather the regular low flow of water into the reservoir affected power generation. This is the major concern for the operations of the Akosombo hydropower plant for energy generation in Ghana.

Ghana has developed two community-based strategies that aim to increase access to quality treatment for malaria, diarrhoea and suspected pneumonia, and to improve household and family practices: integrated Community Case Management (iCCM) and Community-based Health Planning and Services (CHPS). The objective of the study was to assess the effectiveness of iCCM and CHPS on disease knowledge and health behaviour regarding malaria, diarrhoea and pneumonia. A household survey was conducted two and eight years after implementation of iCCM in the Volta and Northern Regions of Ghana respectively, and more than ten years of CHPS implementation in both regions. The study population included 1356 carers of children under- five years of age who had fever, diarrhoea and/or cough in the two weeks prior to the interview. Disease knowledge was assessed based on the knowledge of causes and identification of signs of severe disease and its association with the sources of health education messages received. Health behaviour was assessed based on reported prompt care seeking behaviour, adherence to treatment regime, utilization of mosquito nets and having improved sanitation facilities, and its association with the sources of health education messages received. Health education messages from community-based agents (CBAs) in the Northern Region were associated with the identification of at least two signs of severe malaria (adjusted Odds Ratio (OR) 1.8, 95%CI 1.0, 3.3, p = 0.04), two practices that can cause diarrhoea (adjusted OR 4.7, 95%CI 1.4, 15.5, p = 0.02) 0and two signs of severe pneumonia (adjusted OR 7.7, 95%CI2.2, 26.5, p = 0.01)-the later also associated with prompt care seeking behaviour (p = 0.04). In the Volta Region, receiving messages on diarrhoea from CHPS was associated with the identification of at least two signs of severe diarrhoea (adjusted OR 3.6, 95%CI 1.4, 9.0), p = 0.02). iCCM was associated with prompt care seeking behaviour in the Volta

Highlights: • Alkaline etch of clad AA2024 enhances precipitation of Ce compounds. • Exposure to CeCl 3 solution decreases Volta potential of alkaline etched substrate. • Ce compounds reduce the driving force for initiation of localized attack. - Abstract: AA2024 clad with AA1050 was immersed in CeCl 3 solution to promote deposition of cerium species. The deposition occurs on the entire sample surface for the alkaline etched substrate, while it is very limited for the degreased substrate. The surface potential (Volta potential) was investigated by scanning Kelvin probe force microscopy after different immersion times in CeCl 3 solution. The preferential deposition of Ce compounds at Al–Fe intermetallic sites progressively reduces their Volta potential difference relative to the matrix in the alkaline etched substrate. This reduces the susceptibility to localized attack of the intermetallics as proven by potentiodynamic polarization measurements

People living in areas with highly variable rainfall, experience droughts and floods and often have insecure livelihoods. Small multi-purpose reservoirs (SR) are a widely used form of infrastructures to provide people in such areas with water during the dry season, e.g. in the basins of São Francisco, Brazil, Limpopo, Zimbabwe, Bandama, Ivory Coast and Volta, Ghana. In these areas, the available natural flow in the streams is sometimes less than the flow required for water supply or irrigation, however water can be stored in times of surplus, for example, from a wet season to a dry season. Efficient water management and sound reservoir planning are hindered by the lack of information about the functioning of these reservoirs. Reservoirs in these regions were constructed in a series of projects funded by different agencies, at different times, with little or no coordination among the implementing partners. Poor record keeping and the lack of appropriate institutional support result in deficiencies of information on the capacity, operation, and maintenance of these structures. Estimating the storage capacity of dams is essential to the responsible management of water diversion. Most of SR in these basins have never been evaluated, possibly because the tools currently used for such measurement are labor-intensive, costly and time-consuming. The objective of this research was to develop methodology to estimate small reservoir capacities as a function of their remotely sensed surface areas in the São Francisco, Limpopo, Bandama and Volta basins, as a way to contribute to improve the water resource management in those catchments. Remote sensing was used to identify, localize and characterize small reservoirs. The surface area of each was calculated from satellite images. A sub-set of reservoirs was selected. For each reservoir in the sub-set, the surface area was estimated from field surveys, and storage capacity was estimated using information on reservoir surface

The relationship between mother's nutritional knowledge, maternal education, and child nutritional status (weight-for-age) was the subject of investigation in this study. The data were collected in Ghana on 55 well nourished and 55 malnourished mother-child pairs. A questionnaire designed to collect data on mother's knowledge and practices related to child care and nutrition was administered to the mothers. Data on mother's demographic and socio-economic characteristics as well as child anthropometric data were also collected. A nutrition knowledge score was calculated based on mother's responses to the nutrition related items. Bivariate analysis gave significant associations between child nutritional status and the following variables: time of initiating of breastfeeding, mother's knowledge of importance of colostrum and whether colostrum was given to child, age of introduction of supplementary food, and mother's knowledge about causes of kwashiorkor. The two groups also showed significant differences in their nutrition knowledge scores. Maternal formal education, and marital status were also found to be associated with child nutritional status in bivariate analyses. Further analysis with logistic regression revealed that maternal nutrition knowledge was independently associated with nutritional status after the effects of other significant variables were controlled for. Maternal education on the other hand was not found to be independently associated with nutritional status. These results imply that mother's practical knowledge about nutrition may be more important than formal maternal education for child nutrition outcome.

A 12,000-Year-Long, Annually-Resolved Varve Record Spanning the Last Interglacial from Lake Bosumtwi, Southern Ghana

The impact of continued global warming on the likelihood of severe drought in sub-Saharan West Africa remains uncertain, as climate models generally do not simulate realistic climate dynamics in the region and have inconsistent projections for the future. The Last Interglacial period (LIG), occurring between 128 and 116 thousand years ago, is a partial analog for future warming because at its peak, global temperatures were slightly higher, and this warming was accentuated in Northern Hemisphere terrestrial summer temperatures. Here we present a new, annually-resolved, 12,100-year-long varve record for the LIG from Lake Bosumtwi in southern Ghana (6.5°N, 1.4°W). The abundance of terrigenous elements in the sediment, varve thickness, and the isotope geochemistry and mineralogy of authigenic carbonates in the sediment were used to infer changes in lake level. The varve chronology, varve thickness and elemental abundance records were developed with a new ensemble approach that allows for a more robust determination of uncertainty in the record. The new records reveal a dynamic history of hydrologic variability during the LIG. The LIG lake highstand was lower and shorter-lived than the the prolonged highstand in the early Holocene, and unlike the Holocene, the lake never overflowed during LIG. The overall drier conditions during the LIG are most likely driven by amplified precessional forcing during the interval, resulting in a northward shift in the rainbelt. The LIG, like the Holocene, had two distinct millennial-scale moist intervals, from 125 - 123 and 121 - 120 ka. In both the LIG and the Holocene, these peaks occurred during times of precession-driven insolation maxima in July and October, corresponding to the two rainy seasons in the modern climatology. This suggests that, at least during interglacials, prolonged wet conditions occur at the lake when rainy season insolation is highest. Over the course of the LIG, lake level generally tracked sea surface

Monitoring mass changes in the Volta River basin using GRACE satellite gravity and TRMM precipitation

Directory of Open Access Journals (Sweden)

Vagner G. Ferreira

Full Text Available GRACE satellite gravity data was used to estimate mass changes within the Volta River basin in West African for the period of January, 2005 to December, 2010. We also used the precipitation data from the Tropical Rainfall Measurement Mission (TRMM to determine relative contributions source to the seasonal hydrological balance within the Volta River basin. We found out that the seasonal mass change tends to be detected by GRACE for periods from 1 month in the south to 4 months in the north of the basin after the rainfall events. The results suggested a significant gain in water storage in the basin at reference epoch 2007.5 and a dominant annual cycle for the period under consideration for both in the mass changes and rainfall time series. However, there was a low correlation between mass changes and rainfall implying that there must be other processes which cause mass changes without rainfall in the upstream of the Volta River basin.

The Upper East Region together with the other two regions in Northern Ghana (Upper West and Northern Region) is seen as the locus of perennial food deficit (GPRS, 2003). Despite, the provision of over 200 small scale dams and various mechanisms aimed at poverty alleviation, the region is still plagued with poverty and yearly food shortages. To achieve food security and alleviate poverty in the region however, modernization of agriculture through irrigation is deemed inevitable. While it is true that considerable potential still exists for future expansion of irrigation, it cannot be refuted that water is becoming scarcer in the regions where the need for irrigation is most important, hence mapping the irrigation potential of the region will be the first step toward ensuring sound planning and sustainability of the irrigation developments. In this study, an attempt has been made to map out the irrigation potential of the Upper East Region. The river basin approach was used in assessing the irrigation potential. The catchments drained by The White Volta river, Red volta river, River Sissili and River Kulpawn were considered in the assessment. The irrigation potential for the sub basins was computed by combining information on gross irrigation water requirements for the selected cash crops, area of soil suitable for irrigation and available water resources. The capacity of 80%, 70%, 60% and 50% time of exceedance flow of the available surface water resources in the respective sub basins was estimated. The area that can be irrigated with this flow was computed with selected cropping pattern. Combining the results of the potential irrigable areas and the land use map of the respective sub basins, an irrigation potential map has been generated showing potential sites in the upper east region that can be brought under irrigation. Keywords: Irrigation potential, irrigation water requirement, land evaluation, dependable flow

This study explores the techno-economic potential of rice residues as a bioenergy resource to meet Ghana’s energy demands. Major rice growing regions of Ghana have 70–90% of residues available for bioenergy production. To ensure cost-effective biomass logistics, a thorough cost analysis was made...... for two bioenergy routes. Logistics costs for a 5MWe straw combustion plant were 39.01, 47.52 and 47.89USD/t for Northern, Ashanti and Volta regions respectively. Logistics cost for a 0.25MWe husk gasification plant (with roundtrip distance 10km) was 2.64USD/t in all regions. Capital cost (66......–72%) contributes significantly to total logistics costs of straw, however for husk logistics, staff (40%) and operation and maintenance costs (46%) dominate. Baling is the major processing logistic cost for straw, contributing to 46–48% of total costs. Scale of straw unit does not have a large impact on logistic...

The Sustainable Development of Research Capacity (SDRC) in West Africa is an 18 month project, funded by the German Ministry of Education and Research, to strengthen the research capacity, give access to data and models, and to support the establishment of the newly formed Volta Basin Authority. The SDRC project largely builds on the results and models developed in the framework of the GLOWA Volta Project (GVP), a nine-year, interdisciplinary research project (May 2000 - May 2009). The GVP's central objectives were to analyze the physical and socio-economic determinants of the hydrological cycle in the Volta Basin in the face of global change, and to develop scientifically sound decision support resources. Another major achievement of GVP was the extensive capacity building. Of the 81 participating students (57 Ph.D.'s), 44 originated from West Africa, and 85% of the West African graduates returned to their home countries. The SDRC makes use of the wide range of research results and decision support tools developed in the course of the GVP. It is based on three columns: I. knowledge transfer and strengthening of human capacity, which focus on a training on the modeling of the onset of the rainy season, hydrological, economic, and hydro-economic modeling, and training of geospatial database managers; II. strengthening of infrastructural research capacity through the support of a research instrumentation network through the operation and transfer of a weather station network, a network of tele-transmitted stream gauges; and III. the transfer of a publicly accessible online Geoportal for the dissemination of various geospatial data and research results. At the center of the SDRC effort is the strengthening of the Volta Basin Authority, a river basin authority with a transnational mandate, especially through the transfer of the Geoportal, and the associated training and promotion efforts. The Geoportal is an effort to overcome the data scarcity previously observed in

Living with Bats: The Case of Ve Golokuati Township in the Volta Region of Ghana

Full Text Available Transmission of zoonotic pathogens from bats to humans through direct and indirect contact with bats raises public apprehension about living close to bats. In the township of Ve Golokuati in Ghana, several “camps” of Epomophorus gambianus roost in fruit trees that provide ecosystems services for residents. This study explored human-bat interaction in the township and the potential risks of disease transmission from bats to humans. Data were derived through questionnaire administration and participatory appraisal approach involving focus group discussions, participatory landscape mapping, and transect walk. The study found that most human activities within the township, such as petty-trading, domestic chores, and children’s outdoor recreation, exposed people to bats. Though there have been no reported cases of disease spillover from bats to humans from the perspective of residents and from medical records, respondents whose activities brought them closer to bats within the township were found to be more likely to experience fevers than those who do not interact with bats frequently. The study recommends education of community members about the potential risks involved in human-bat interactions and makes suggestions for reducing the frequent interactions with and exposure to bats by humans.

Environmental protection implications of the electric power restructuring in Ghana

The electric utility industries in most African countries are confronted by the twin-problem of deficient capacity and lack of adequate financial resources to undertake capacity expansion of their respective systems. The critical aspects of power sector reform taking place in many countries are the shift away from state-owned monopoly model towards private sector participation and some competition in the industry. Hydropower plants dominate power system in most countries in the region. Ghana, which is the focus of this study, has such characteristics. The hydrology of the river on which the two dams (Akosombo and Kpong hydropower plants) are built is increasingly becoming uncertain, and besides, the power output from the two plants is insufficient to meet the increasing electricity demand of the country. The alternative is to build thermal power plants to complement the two hydropower plants. The purposes of the study are: (i) to assess the environmental (more specifically air pollution) implications of changing fuel mix in power generation in Ghana within the context of the ongoing reform of the power sector and (ii) to assess the capacity of the environment protection agencies to regulate, monitor and enforce regulations in the emerging electricity industry. The study uses a spreadsheet-based simulation model to determine the potential levels of certain air pollutants - CO{sub 2}, SO{sub 2} and NO{sub x} - that would result from changes in fuel mix for electricity generation. Using different capacity expansion options proposed for The Volta River Authority (VRA) between 1997-2013, the levels of these air pollutants are estimated. The study further describes other potential environmental impacts of changes in fuel mix in power generation. (au)

An earlier study established that Upper Volta children respond to vaccination with the Enders live attenuated measles strain in the same general fashion as do children in the USA. The present report describes a second pilot project carried out in Ouagadougou, Upper Volta. During this investigation various mixtures of live measles, smallpox and 17D yellow fever vaccines were introduced into susceptible infants by jet injection. Combining the attenuated virus vaccines did not alter or accentuate the characteristic clinical reactions elicited by the individual components, nor was there evidence of significant immunological interference. From this experience it is concluded that combined vaccination with these agents may be safely and effectively employed in larger programmes as the need dictates.

Globally, the cement industry has been identified as one which causes significant particle pollution. In Ghana, environmental research in the neighborhood of the cement industry especially on human health is scanty. In the present work, attempts were made to evaluate the concentration of airborne dust at various distances and directions around the Diamond Cement Factory in the Volta Region of Ghana. The samples of dust were collected on filter papers and later analyzed for the concentration (mg/kg) of 232 Th and 23 '8U using neutron activation analysis. The principal objective of the study was to generate data intended at assessing the annual effective dose due to 232 Th and 238 U inhalation for both adult and children population living in the vicinity of cement factory. The data generated were supposed to assist in remediation decision making, if required. The study recorded a few incidences of higher total dust load concentrations as compared to the permissible limit of 150 μg/m 3 specified by the Ghana Environmental Protection Agency. The calculated mean effective doses were 28.2 ± 1.06 μSv/year and 25.9 ± 0.91 μSv/year for both adult and child, respectively. From the radiological point of view, the study concluded that the people living in the vicinity of the cement factory are not at risk to significant radiological hazards. However, the study indicated the need to have a complete evaluation of the impact of the factory on the environment assessment programs which should include both chemical and radiological toxicity.

Increasing prevalence of non-communicable diseases (NCDs) has been observed in Ghana as in other developing countries. Past research focused on NCDs among adults. Recent researches, however, provide evidence on NCDs among children in many countries, including Ghana. Beliefs about the cause of NCDs among children may be determined by the socioeconomic status of parents and care givers. This paper examines the relationship between educational status of parents and/or care givers of children with NCDs on admission and their beliefs regarding NCDs among children. A total of 225 parents and/or care givers of children with NCDS hospitalized in seven hospitals in three regions (Greater Accra, Ashanti and Volta) were selected for the study. Statistical techniques, including the chi-square and multinomial logistic regression, were used for the data analysis. Educational status is a predictor of care giver's belief about whether enemies can cause NCDs among children or not. This is the only belief with which all the educational categories have significant relationship. Also, post-secondary/polytechnic (p-value =0.029) and university (p-value = 0.009) levels of education are both predictors of care givers being undecided about the belief that NCDs among children can be caused by enemies, when background characteristics are controlled for. Significant relationship is found between only some educational categories regarding the other types of beliefs and NCDs among children. For example, those with Middle/Juniour Secondary School (JSS)/Juniour High School (JHS) education are significantly undecided about the belief that the sin of parents can cause NCDs among children. Education is more of a predictor of the belief that enemies can cause NCDs among children than the other types of beliefs. Some categories of ethnicity, residential status and age have significant relationship with the beliefs when background characteristics of the parents and/or care givers were controlled

Structure of a hexameric form of RadA recombinase from Methanococcus voltae

International Nuclear Information System (INIS)

Du, Liqin; Luo, Yu

2012-01-01

Hexameric rings of RadA recombinase from M. voltae have been crystallized. Structural comparisons suggest that homologues of RadA tend to form double-ringed assemblies. Archaeal RadA proteins are close homologues of eukaryal Rad51 and DMC1 proteins and are remote homologues of bacterial RecA proteins. For the repair of double-stranded breaks in DNA, these recombinases promote a pivotal strand-exchange reaction between homologous single-stranded and double-stranded DNA substrates. This DNA-repair function also plays a key role in the resistance of cancer cells to chemotherapy and radiotherapy and in the resistance of bacterial cells to antibiotics. A hexameric form of a truncated Methanococcus voltae RadA protein devoid of its small N-terminal domain has been crystallized. The RadA hexamers further assemble into two-ringed assemblies. Similar assemblies can be observed in the crystals of Pyrococcus furiosus RadA and Homo sapiens DMC1. In all of these two-ringed assemblies the DNA-interacting L1 region of each protomer points inward towards the centre, creating a highly positively charged locus. The electrostatic characteristics of the central channels can be utilized in the design of novel recombinase inhibitors

Exploring the Viability of Solar Photovoltaic for Rural Water Supply in Ghana: A Case Study of Agotime-Ziope District of the Volta Region

Availability of good drinking water is a key factor for health and quality of life. In urban locations of Ghana, water from large rivers is abstracted and treated before it is supplied to the urban people by the use of the grid. However access to potable water is difficult in rural communities of the country because these locations are remote from the grid (or they experience unreliable power supply) and water infrastructure. They are however endowed with abundant sunshine (5-8 hours per day ...

Culture and the environment in Ghana

Science.gov (United States)

Dyasi, Hubert M.

1985-03-01

The traditional culture of Ghana stressed a strong relationship with the environment, and a culturally acceptable environmental management resulted from strictures and taboos related to the land. Following its independence in 1957, Ghana has enacted laws that reflect an enlightened environmental policy. These are especially important because of the difficulties Ghana has had in its economic development using Western technology that has damaged the fragile tropical ecosystem. A key aspect of Ghana's policy is the attempt to marry scientific knowledge and traditional beliefs for environmentally sound management of Ghana's resources.

From the pile of Volta to fuel cells

CERN Multimedia

2000-01-01

Volta designed his pile by associating two different metals and liquid conducting electricity. He recognized the possibility of increasing the "voltage" by placing cells in series (a pile). This invention led to a wonderful development of science and technology, including the concept of fuel cell in 1839 by GROVE. But efficient research began only in the 20th century after the development of electrochemical thermodynamics by Nemst. His assistants conducted research on fuel cell designed by Bacon before world warII, developed NASA for the Apollo space flights. Research for effecient and clean electricity generation has led to the defferent kinds of fuel cells now under development (APC, PAPC, PAMPC, MCPC and SOPC) which will be briefly described with their applications.

Land Water-Storage Variability over West Africa: Inferences from Space-Borne Sensors

2018-03-01

Full Text Available The potential of terrestrial water storage (TWS inverted from Gravity Recovery and Climate Experiment (GRACE measurements to investigate water variations and their response to droughts over the Volta, Niger, and Senegal Basins of West Africa was investigated. An altimetry-imagery approach was proposed to deduce the contribution of Lake Volta to TWS as “sensed” by GRACE. The results showed that from April 2002 to July 2016, Lake Volta contributed to approximately 8.8% of the water gain within the Volta Basin. As the signal spreads out far from the lake, it impacts both the Niger and Senegal Basins with 1.7% (at a significance level of 95%. This figure of 8.8% for the Volta Basin is approximately 20% of the values reported in previous works. Drought analysis based on GRACE-TWS (after removing the lake’s contribution depicted below-normal conditions prevailing from 2002 to 2008. Wavelet analysis revealed that TWS changes (fluxes and rainfall as well as vegetation index depicted a highly coupled relationship at the semi-annual to biennial periods, with common power covariance prevailing in the annual frequencies. While acknowledging that validation of the drought occurrence and severity based on GRACE-TWS is needed, we believe that our findings shall contribute to the water management over West Africa.

Full Text Available A reforma do sistema de saúde brasileiro é um dos mais bem-sucedidos exemplos de descentralização institucional, a despeito de ser uma experiência que contém limites. Esses limites estão relacionados com a natureza das instituições responsáveis pela prestação dos serviços, e pelas demandas apresentadas pela população. Na Constituição de 1998 que deu forte ênfase à democratização das relações políticas, ocorreu a incorporação da saúde enquanto direito de cidadania, através do qual foram fixados atributos para o Estado, de modo a definir um outro patamar em seu relacionamento com a sociedade. O direito à saúde conduziu a uma centralidade nas questões relativas ao acesso aos serviços de saúde. Assim, produziu-se um reordenamento político e institucional do aparato estatal, orientado para potencializar a ação dos municípios, pois essa era a esfera de governo que caberia ampliar a oferta local de serviços básicos de saúde. Neste sentido, o direito à saúde torna-se direito universal a serviços locais de atenção à saúde. O presente estudo é uma investigação exploratória sobre a relação da demanda e oferta, na perspectiva da prática quotiadiana dos diversos atores. Essa relação foi examinada através de um estudo de um caso concreto, de reforma do sistema de saúde do município de Volta Redonda, o qui se desenvolveu um modelo de SUS denominado "Em Defesa da Vida", que é a base dessa investigação.

Kotir, Julius H; Smith, Carl; Brown, Greg; Marshall, Nadine; Johnstone, Ron

2016-12-15

In a rapidly changing water resources system, dynamic models based on the notion of systems thinking can serve as useful analytical tools for scientists and policy-makers to study changes in key system variables over time. In this paper, an integrated system dynamics simulation model was developed using a system dynamics modelling approach to examine the feedback processes and interaction between the population, the water resource, and the agricultural production sub-sectors of the Volta River Basin in West Africa. The objective of the model is to provide a learning tool for policy-makers to improve their understanding of the long-term dynamic behaviour of the basin, and as a decision support tool for exploring plausible policy scenarios necessary for sustainable water resource management and agricultural development. Structural and behavioural pattern tests, and statistical test were used to evaluate and validate the performance of the model. The results showed that the simulated outputs agreed well with the observed reality of the system. A sensitivity analysis also indicated that the model is reliable and robust to uncertainties in the major parameters. Results of the business as usual scenario showed that total population, agricultural, domestic, and industrial water demands will continue to increase over the simulated period. Besides business as usual, three additional policy scenarios were simulated to assess their impact on water demands, crop yield, and net-farm income. These were the development of the water infrastructure (scenario 1), cropland expansion (scenario 2) and dry conditions (scenario 3). The results showed that scenario 1 would provide the maximum benefit to people living in the basin. Overall, the model results could help inform planning and investment decisions within the basin to enhance food security, livelihoods development, socio-economic growth, and sustainable management of natural resources.

Una particolare attenzione sarà riservata alla rilevazione degli atteggiamenti nei confronti dell’akan, la lingua più importante (per numero di parlanti e grado di elaborazione raggiunto tra quelle parlate in territorio ghanese. Attraverso l’osservazione dei dati contenuti in un campione di 90 questionari somministrati agli studenti in forma anonima, si cercherà di descrivere gli atteggiamenti degli studenti stessi nei riguardi dell’introduzione dell’akan come lingua di insegnamento nei diversi gradi del locale sistema scolastico, nonché gli atteggiamenti in relazione alla possibilità di discutere, servendosi dell’akan, una serie di argomenti tecnici e specialistici. L’analisi dei dati raccolti rivelerà che l’eventuale impiego dell’akan come lingua di insegnamento nell’ambito del locale sistema scolastico sarebbe avversato non soltanto dagli studenti in possesso di un certo grado di competenza dell’akan come lingua seconda o come lingua veicolare, ma anche dagli stessi studenti che riconoscono nell’akan la propria lingua materna. La capacità di discutere in lingua inglese un ampio ventaglio di discipline tecniche e specialistiche può dunque essere considerata la competenza in generale più ambita ed apprezzata tra quelle offerte dal locale sistema educativo.

1983-01-01

Malnutrition-associated risk factors have been studied in Upper Volta following a multivariate statistic analysis performed with a computer (Manova). The multiple correlation coefficients for 7 predictors were 0.14 for the children and 0.34 for the women. Results show that the nutritional situation worsens when the density of the population leads to an over exploitation of the land in the North West. Two different life-styles, i.e. cattle breeding and agriculture determine strikingly different nutritional situations among women and children. Family factors are also important to the nutritional status of the children.

Full Text Available Abstract Background Understanding regional variation in patient satisfaction about healthcare systems (PHCs on the quality of services provided is instrumental to improving quality and developing a patient-centered healthcare system by making it more responsive especially to the cultural aspects of health demands of a population. Reaching to the innovative National Health Insurance Scheme (NHIS in Ghana, surpassing several reforms in healthcare financing has been a milestone. However, the focus of NHIS is on the demand side of healthcare delivery. Studies focusing on the supply side of healthcare delivery, particularly the quality of service as perceived by the consumers are required. A growing number of studies have focused on regional differences of patient satisfaction in developed countries, however little research has been conducted concerning patient satisfaction in resource-poor settings like in Ghana. This study was therefore dedicated to examining the variation in satisfaction across rural and urban women in Ghana. Methods Data for the present study were obtained from the latest demographic and health survey in Ghana (GDHS 2014. Participants were 3576 women aged between 15 and 49 years living in non-institutional settings in Ghana. Summary statistics in percentages was used to present respondents’ demographic, socioeconomic characteristics. Chi-square test was used to find association between urban-rural differentials with socio-economic variables. Multiple logistic regression was performed to measure the association of being satisfied with primary healthcare services with study variables. Model fitness was tested by pseudo R 2. Statistical significance was set at p < 0.05. Results The findings in this study revealed that about 57.1% were satisfied with primary health care services. The urban and rural areas reported 57.6 and 56.6% respectively which showed no statistically significant difference (z = 0.64; p = 0.523; 95

Estimating water storage changes and sink terms in Volta Basin from satellite missions

Full Text Available The insufficiency of distributed in situ hydrological measurements is a major challenge for hydrological studies in many regions of the world. Satellite missions such as the Gravity Recovery and Climate Experiment (GRACE and the Tropical Rainfall Measurement Mission (TRMM can be used to improve our understanding of water resources beyond surface water in poorly gauged basins. In this study we combined GRACE and TRMM to investigate monthly estimates of evaporation plus runoff (sink terms using the water balance equation for the period from January 2005 to December 2010 within the Volta Basin. These estimates have been validated by comparison with time series of sink terms (evaporation plus surface and subsurface runoff from the Global Land Data Assimilation System (GLDAS. The results, for the period under consideration, show strong agreement between both time series, with a root mean square error (RMSE of 20.2 mm/month (0.67 mm/d and a correlation coefficient of 0.85. This illustrates the ability of GRACE to predict hydrological quantities, e.g. evaporation, in the Volta Basin. The water storage change data from GRACE and precipitation data from TRMM all show qualitative agreement, with evidence of basin saturation at approximately 73 mm in the equivalent water column at the annual and semi-annual time scales.

SCANNING VOLTA POTENTIALS MEASUREMENTS OF METALS IN IRRADIATED AIR.

Energy Technology Data Exchange (ETDEWEB)

ISAACS, H.S.; ADZIC, G.; AND ENERGY SCIENCES AND TECHNOLOGY DEPARTMENT; JEFFCOATE, C.S.

2000-10-22

A method for direct dc measurement of the Volta potential is presented. High intensity synchrotron x-ray beams were used to locally irradiate the atmosphere adjacent to the metal surface and produce a conducting path between a sample and a reference probe. The direct measurements of potential in the ionized air could be made at probe heights of around 1 mm compared to less than 0.1 mm for the Kelvin probe. The measurements were similar to traditional Kelvin probe measurements, but had a poorer spatial resolution. In contrast to the Kelvin probe methods, the approach described allows observation of the current as a function of impressed voltage. Methods to improve the special resolution of the technique and applications to corrosion under coating will be presented.

Investigation of Temperature Dynamics in Small and Shallow Reservoirs, Case Study: Lake Binaba, Upper East Region of Ghana

Directory of Open Access Journals (Sweden)

Ali Abbasi

2016-03-01

Full Text Available An unsteady fully three-dimensional model of Lake Binaba (a shallow small reservoir in semi-arid Upper East Region of Ghana has been developed to simulate its temperature dynamics. The model developed is built on the Reynolds Averaged Navier–Stokes (RANS equations, utilizing the Boussinesq approach. As the results of the model are significantly affected by the physical conditions on the boundaries, allocating appropriate boundary conditions, particularly over a water surface, is essential in simulating the lake’s thermal structure. The thermal effects of incoming short-wave radiation implemented as a heat source term in the temperature equation, while the heat fluxes at the free water surface, which depend on wind speed, air temperature, and atmospheric stability conditions are considered as temperature boundary condition. The model equations were solved using OpenFOAM CFD toolbox. As the flow is completely turbulent, which is affected by the complex boundary conditions, a new heat transfer solver and turbulence model were developed to investigate the spatial and temporal distribution of temperature in small and shallow inland water bodies using improved time-dependent boundary conditions. The computed temperature values were compared with four days of observed field data. Simulated and observed temperature profiles show reasonable agreement where the root mean square error (RMSE over the simulation period ranges from 0.11 to 0.44 °C in temporal temperature profiles with an average value of 0.33 °C. Results indicate that the model is able to simulate the flow variables and the temperature distribution in small inland water bodies with complex bathymetry.

The rate of deforestation in Ghana is alarming and urgent steps need to be taken to reverse the trend, Robert D. Mann, a British tropical agriculturist, has warned. He says, "There will be further disintegration of the local climate, deterioration of soil fertility and reduced food-crop production, if the present trend of denudation by felling trees and uncontrolled bush fires is not halted and reversed." Mann, who has conducted research on "deforestation, drought and famine in Africa" was in Ghana recently to speak on the "role of the Church in West Africa in stimulating action to combat desertification". Representatives of protestant churches in Ghana, Togo, Liberia, Gambia, Nigeria, Cote d'Ivoire and Sierra Leone attended the 3-day conference which was organized by the Overseas Department of the British Methodist Church. It was to enable participants to share perspectives on the nature, scale and seriousness of the deforestation problem. Participants also exchanged experiences on village-based projects for promoting tree planting and agro-forestry, and developed strategies for the rural development programs. Robert Mann noted that Ghana was not only affected by its proximity to the Sahel, but also by its own deforestation. The situation in Ghana, once renowned for her extensive forests and woodland, has now drastically changed. By 1980/81 the area of closed forest had been reduced to 17,000 sq km from 47,9000 sq km in 1937/38. He said in 1939 the volume of wood exported from Ghana was 42,450 cubic meters but it rose to 1,471,600 cubic meters by 1987. Such activities, Mann said, put severe strain on the environment and affected both the economy and sociocultural basis of the country. full text

Rainfall erosivity map for Ghana

International Nuclear Information System (INIS)

Oduro Afriyie, K.

1995-10-01

Monthly rainfall data, spanning over a period of more than thirty years, were used to compute rainfall erosivity indices for various stations in Ghana, using the Fournier index, c, defined as p 2 /P, where p is the rainfall amount in the wettest month and P is the annual rainfall amount. Values of the rainfall erosivity indices ranged from 24.5 mm at Sunyani in the mid-portion of Ghana to 180.9 mm at Axim in the south western coastal portion. The indices were used to construct a rainfall erosivity map for the country. The map revealed that Ghana may be broadly divided into five major erosion risk zones. The middle sector of Ghana is generally in the low erosion risk zone; the northern sector is in the moderate to severe erosion risk zone, while the coastal sector is in the severe to extreme severe erosion risk zone.

Cardiothoracic surgical experience in Ghana.

Science.gov (United States)

Tettey, Mark; Tamatey, Martin; Edwin, Frank

2016-10-01

Ghana is one of the few low-to-middle-income countries in sub-Saharan Africa able to consistently sustain a cardiothoracic program with locally trained staff for more than two decades. Cardiothoracic surgery practice in Ghana started in 1964 but faltered from a combination of political and the economic problems. In 1989, Dr. Kwabena Frimpong-Boateng, a Ghanaian cardiothoracic surgeon trained in Hannover, rekindled interest in cardiothoracic surgery and in establishing a National Cardiothoracic Centre. His vision and leadership has brought cardiothoracic surgery practice in Ghana to its current high level. As a result, the medical landscape of what is achievable locally in both pediatric and adult patients has changed substantially: outbound medical travel that used to be common among Ghanaian cardiovascular patients has been reduced drastically. Ghana's National Cardiothoracic Center (NCTC), the only tertiary center in the country for cardiothoracic surgical pathology manages all such patients that were previously referred abroad. The NCTC has become a medical/surgical hub in the West African sub-region providing service, training, and research opportunities to neighboring countries. The Centre is accredited by the West African College of Surgeons as a center of excellence for training specialists in cardiothoracic surgery. Expectedly, practicing cardiothoracic surgery in such a resource-poor setting has peculiar challenges. This review focuses on the history, practice, successes, and challenges of cardiovascular and thoracic surgery in Ghana.

Computing the net primary productivity for a savannah-dominated ecosystem using stable isotopes: a case study of the Volta River Basin

International Nuclear Information System (INIS)

Hayford, E.K.

2008-01-01

The hydrologic systems and the terrestrial ecosystem of the Volta river basin in West Africa, play important role in the carbon cycle. This is so because of the coupling of water vapour release and CO 2 uptake during photosynthesis, expressed as water use efficiency or transpiration ratio. Hydrologic and land-cover data, together with stable isotope ratio measurements of δ 18 O and δD, and data from the global network of isotopes in precipitation (GNIP) are used to determine the net primary productivity (NPP) of the Savannah-dominated ecosystem. The δ 18 O and δD values in the Volta rivers range from -4.72 to 2.37 mm -l and from -35.28 to 9.30 mm -1 SMOW, respectively. The results indicate that the vegetation is supported by 380 km 3 of rainfall, out of which 50% is returned to the atmosphere via plant transpiration. Associated with annual transpiration is the NPP of 0.170 x 10 15 gCyr -1 or 428 gCm -2 from the terrestrial ecosystem. Modelled estimates of heterotrophic soil respiration in this study slightly exceeded the NPP estimates, implying a small source of CO 2 to the atmosphere. This condition does not favour the postulated existence of a major sink of atmospheric CO 2 in the Volta basin. (au)

Ghana depends mainly on hydro-systems for electricity generation. In 1984, 1998, 2003 and 2007, there was drastic shortfalls in hydro-generation due to severe droughts. In 2007, the shortfall in generation was compounded by high prices of light crude oil. In May 2007, the government set-up a 7-man Presidential Committee on feasibility of a Nuclear Power Programme. Ghana’s electricity demand was projected to increase at 7.7% p.a. between 2004 and 2030. Per capita electricity demand is expected to increase from 253 kWh in 2004 to 1120 kWh in 2030. Peak electricity demand was expected to increase from 1095 MW in 2004 to 6700 MW in 2030. Ghana received IAEA assistance to undertake a national TCP GHA/0/011: “Evaluating the role of Nuclear Power in Future Generation Mix”. Under the national TCP GHA/0/011, a proposal for establishing NEPIO – (an Inter-ministerial Steering Committee to be chaired by the Minister of Energy) based on IAEA recommendations was submitted to the Minister of Energy. Ghana Atomic Energy Commission in partnership with other stakeholders and support from the IAEA did prepared a draft nuclear bill. The draft Ghana Nuclear Bill also proposed the establishment of an independent Ghana Nuclear Regulatory Authority. The Authority is mandated to license and regulate all nuclear installations including power plants. No potential sites for nuclear power plant and waste disposal had been identified yet for evaluation. Potential sites for nuclear power plants and waste disposal were identified and assessed under the IAEA national TCP GHA/0/011. Ghana Atomic Energy Commission (i.e. GAEC) and the University of Ghana with support from the IAEA have established the Graduate School of Nuclear and Allied Sciences (i.e. SNAS) for training nuclear expert

Human Resource Local Content in Ghana's Upstream Petroleum Industry

Science.gov (United States)

Benin, Papa

Enactment of Ghana's Petroleum (Local Content and Local Participation) Regulations, 2013 (L.I. 2204) was intended to regulate the percentage of local products, personnel, financing, and goods and services rendered within Ghana's upstream petroleum industry value chain. Five years after the inception of Ghana's upstream oil and gas industry, a gap is evident between the requirements of L.I. 2204 and professional practice. Drawing on Lewin's change theory, a cross-sectional study was conducted to examine the extent of differences between the prevailing human resource local content and the requirements of L.I. 2204 in Ghana's upstream petroleum industry. The extent to which training acquired by indigenous Ghanaians seeking jobs in Ghana's oil fields affects the prevalent local content in its upstream petroleum industry was also examined. Survey data were collected from 97 management, technical, and other staff in 2 multinational petroleum companies whose oil and gas development plans have been approved by the Petroleum Commission of Ghana. To answer the research questions and test their hypotheses, one-way ANOVA was performed with staff category (management, technical, and other) as the independent variable and prevalent local content as the dependent variable. Results indicated that prevailing local content in Ghana's upstream petroleum industry meets the requirements of L.I. 2204. Further, training acquired by indigenous Ghanaians seeking jobs in Ghana's oil fields affects the prevalent local content in its offshore petroleum industry. Findings may encourage leaders within multinational oil companies and the Petroleum Commission of Ghana to organize educational seminars that equip indigenous Ghanaians with specialized skills for working in Ghana's upstream petroleum industry.

Full Text Available Resumo Dentre os segmentos turísticos praticados em contato direto com a natureza, o ecoturismo se destaca por ser considerado de baixo impacto, gerador de conhecimentos e conscientização ambiental. Apesar desses aspectos positivos, a falta de planejamento que vise ordenar as atividades e minimizar os impactos negativos que possam ser provocados na paisagem, faz com que esse segmento seja desenvolvido muitas vezes de forma desvirtuada de seu real conceito. O presente estudo teve como proposta o planejamento de um circuito de ecoturismo na Reserva Volta Velha - Itapoá - Santa Catarina, utilizando-se a paisagem como recurso técnico. O resultado obtido foi o planejamento de um circuito de ecoturismo com interferências de baixa magnitude nos sítios ambientais e histórico-culturais presentes na reserva. Palavras-chave: planejamento turístico; paisagem; reserva Volta Velha; Itapoá; Santa Catarina. Abstract Among the tourist segments which involve direct contact with nature, ecotourism stands out for having low impact, generating knowledge, and bringing environmental awareness as well. Yet in spite of these positive aspects, the lack of planning in the sense of coordinating activities and minimizing the negative impacts which may arise at the landscape, causes its chore concept to lose the original appeal. This study seeks to plan an ecotourism circuit at Reserva Volta Velha - Itapoá - Santa Catarina, utilizing the landscape as a planning resource. The result of the study was a planning an ecotourism circuit with low-magnitude interferences in the environmental and historic/cultural sites found in the reserve.

Despite recurring outbreaks of cholera in Ghana, very little has been reported on assessments of outbreak response activities undertaken in affected areas. This study assessed the response activities undertaken in two districts, Akatsi District in Volta Region and Komenda-Edina-Eguafo-Abirem (KEEA) Municipal in Central Region during the 2012 cholera epidemic in Ghana. We conducted a retrospective assessment of the events, strengths and weaknesses of the cholera outbreak response activities in the two districts making use of the WHO cholera evaluation tool. Information sources included surveillance and facility records, reports and interviews with relevant health personnel involved in the outbreak response from both district health directorates and health facilities. We collected data on age, sex, area of residence, date of reporting to health facility of cholera cases, district population data and information on the outbreak response activities and performed descriptive analyses of the outbreak data by person, time and place. The cholera outbreak in Akatsi was explosive with a high attack rate (AR) of 374/100,000 and case fatality rate (CFR) of 1.2 % while that in KEEA was on a relatively smaller scale AR of 23/100,000 but with a high case fatality rate of 18.8 %. For both districts, we identified multiple strengths in the response to the outbreak including timely notification of the district health officials which triggered prompt investigation of the suspected outbreak facilitating confirmation of cholera and initiation of public health response activities. Others were coordination of the activities by multi-sectoral committees, instituting water, sanitation and hygiene measures and appropriate case management at health facilities. We also found areas that needed improvement in both districts including incomplete surveillance data, sub-optimal community based surveillance considering the late reporting and the deaths in the community and the inadequate

Ghana and the nuclear power option

International Nuclear Information System (INIS)

Fletcher, J.J.; Ennison, I.

2000-01-01

For every country, dependable and continuous supply of electricity is a prerequisite for ensuring sustainable development. In Ghana, Ghanaians have currently known the consequences of disrupted and inadequate supply of electricity. Globally too the call of ''Agenda 21'' of the Rio de Janeiro Conference (Earth Summit) to engage in the development and supply of electricity in a sustainable manner imposes on us certain limitations in our choice of energy option to utilise. Taking into account the high economic and population growths with the subsequent increase in demand for electricity in the 21st century, the fact that Ghana has no coal and imports oil which will be in dwindling supply in the 21st century and that the total hydro supply in Ghana will not be sufficient for our electricity demand in the next century, this paper proposes that Ghana starts now to plan for the introduction of the nuclear option so that in the long term we may have in place an environmentally friendly, dependable and reliable supply of energy. The paper also highlights the economic competitiveness of nuclear power over the other energy options in Ghana and addresses the apprehension and misunderstanding surrounding the nuclear power option.

Medical physics has been an indispensable and strategic stakeholder in the delivery of radiological services to the healthcare system of Ghana. The practice has immensely supported radiation oncology and medical imaging facilities over the years, while the locally established training programme continues to produce human resource to feed these facilities. The training programme has grown to receive students from other African countries in addition to local students. Ghana has been recognised by the International Atomic Energy Agency as Regional Designated Centre for Academic Training of Medical Physicists in Africa. The Ghana Society for Medical Physics collaborates with the School of Nuclear and Allied Sciences of the University of Ghana to ensure that training offered to medical physicists meet international standards, making them clinically qualified. The Society has also worked together with other bodies for the passage of the Health Profession's Regulatory Bodies Act, giving legal backing to the practice of medical physics and other allied health professions in Ghana. The country has participated in a number of International Atomic Energy Agency's projects on medical physics and has benefited from its training courses, fellowships and workshops, as well as those of other agencies such as International Organization for Medical Physics. This has placed Ghana's medical physicists in good position to practice competently and improve healthcare. Copyright © 2016 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd.

Turning around an ailing district hospital: a realist evaluation of strategic changes at Ho Municipal Hospital (Ghana

Directory of Open Access Journals (Sweden)

Kegels Guy

2010-12-01

Full Text Available Abstract Background There is a growing consensus that linear approaches to improving the performance of health workers and health care organisations may only obtain short-term results. An alternative approach premised on the principle of human resource management described as a form of 'High commitment management', builds upon a bundles of balanced practices. This has been shown to contribute to better organisational performance. This paper illustrates an intervention and outcome of high commitment management (HiCom at an urban hospital in Ghana. Few studies have shown how HiCom management might contribute to better performance of health services and in particular of hospitals in low and middle-income settings. Methods A realist case study design was used to analyse how specific management practices might contribute to improving the performance of an urban district hospital in Ho, Volta Region, in Ghana. Mixed methods were used to collect data, including document review, in-depth interviews, group discussions, observations and a review of routine health information. Results At Ho Municipal Hospital, the management team dealt with the crisis engulfing the ailing urban district hospital by building an alliance between hospital staff to generate a sense of ownership with a focus around participative problem analysis. The creation of an alliance led to improving staff morale and attitude, and contributed also to improvements in the infrastructure and equipment. This in turn had a positive impact on the revenue generating capacity of the hospital. The quick turn around in the state of this hospital showed that change was indeed possible, a factor that greatly motivated the staff. In a second step, the management team initiated the development of a strategic plan for the hospital to maintain the dynamics of change. This was undertaken through participative methods and sustained earlier staff involvement, empowerment and feelings of reciprocity. We

Wuertenberger, L.; Bunzeck, I.G.; Van Tilburg, X.

2011-04-01

To support the development of a National Climate Change Policy Framework (NCCPF) and a further harmonization of climate change related activities in Ghana, the Ministry of Finance and Economic Planning (MoFEP) and the Ministry of Environment, Science and Technology (MEST) expressed demand for a mapping of the most important past and current climate change related initiatives in the country, and of international climate change related funding opportunities, that Ghana might be able to access. The initiatives mapping demonstrates Ghana's longstanding engagement with climate change, dating back to more than 15 years ago. The report shows a multitude of activities including a number of large (5 mln. USD to > 100 mln. USD), GEF or World Bank financed projects, and a range of smaller projects (in the order of 100 000 - 500 000 USD). The majority of current initiatives are related to forestry and REDD. This report concludes with a discussion on observed trends, such as a broadening involvement of MDAs in adaptation initiatives and a focus on low carbon growth, and of points for attention, such as a need for coordination, for private sector involvement and supporting systems (such as institutional capacity, governance and monitoring systems)

Problems and Prospects of Millennium Development Goals in Ghana

Directory of Open Access Journals (Sweden)

Olusola Olasupo

2016-12-01

Full Text Available Ghana, like other developing nations, was not left behind in embracing the eight time-bound Millennium Development Goals (MDGs in September 2000. The millennium development goals aimed towards peace and good standards of living have been faced with series of problems in its attainment in Ghana. These problems have undermined the extent to which Ghana could achieve the MDGs. The study adopting qualitative research method shows that Ghana is faced with difficulty in achieving these eight millennium development goals in certain portions of the nation most especially in the rural communities due to lack of infrastructure. The study therefore recommends that Ghana should focus more on improving the standard of living of the rural dwellers by increasing the public services in the area.  The need for Ghana to focus more on solving these problems is strategic for a better result in this new era of Sustainable Development Goals.

In order to measure and analyse the technical efficiency of district hospitals in Ghana, the specific objectives of this study were to (a) estimate the relative technical and scale efficiency of government, mission, private and quasi-government district hospitals in Ghana in 2005; (b) estimate the magnitudes of output increases and/or input reductions that would have been required to make relatively inefficient hospitals more efficient; and (c) use Tobit regression analysis to estimate the impact of ownership on hospital efficiency. In the first stage, we used data envelopment analysis (DEA) to estimate the efficiency of 128 hospitals comprising of 73 government hospitals, 42 mission hospitals, 7 quasi-government hospitals and 6 private hospitals. In the second stage, the estimated DEA efficiency scores are regressed against hospital ownership variable using a Tobit model. This was a retrospective study. In our DEA analysis, using the variable returns to scale model, out of 128 district hospitals, 31 (24.0%) were 100% efficient, 25 (19.5%) were very close to being efficient with efficiency scores ranging from 70% to 99.9% and 71 (56.2%) had efficiency scores below 50%. The lowest-performing hospitals had efficiency scores ranging from 21% to 30%.Quasi-government hospitals had the highest mean efficiency score (83.9%) followed by public hospitals (70.4%), mission hospitals (68.6%) and private hospitals (55.8%). However, public hospitals also got the lowest mean technical efficiency scores (27.4%), implying they have some of the most inefficient hospitals.Regarding regional performance, Northern region hospitals had the highest mean efficiency score (83.0%) and Volta Region hospitals had the lowest mean score (43.0%).From our Tobit regression, we found out that while quasi-government ownership is positively associated with hospital technical efficiency, private ownership negatively affects hospital efficiency. It would be prudent for policy-makers to examine the

Demographic patterns and sustainable development in Ghana.

Science.gov (United States)

Tawiah, E O

1995-01-01

There is a growing recognition that the present demographic patterns in sub-Saharan Africa, including Ghana, do not augur well for the achievement of sustainable development. Ghana is characterized by a youthful population, rapid population growth, uneven population distribution, high fertility, and rural-urban migration which has brought human numbers into collision with resources to sustain them. It is submitted that the issues discussed are equally applicable to the subregion as well. The estimated population in 1993 was about 16.4 million. The population of Ghana increased from 1970 to 1984 at a rate of growth of 2.6% per annum. The proliferation of small settlements has serious implications for sustainable development. Urban centers comprised about 12.9% of the total population in 1948, 23% in 1960, 28.3% in 1970, and 31.3% in 1984. The average woman in Ghana still has more than six children. The 1988 Ghana Demographic and Health Survey (GDHS) indicated that the median age at first marriage for women was 16.5 years. Contraceptive use is low in sub-Sahara Africa. Currently married women (15-49) currently using any modern method ranged from 1% in Burundi (1987) and Mali (1987) to 36% in Zimbabwe (1988/89). The rapid population growth in Ghana, coupled with the concentration of infrastructural facilities and job opportunities in the urban centers, has resulted in a massive rural-urban migration. Basic social facilities like health, water, housing, and electricity have been stretched to their breakpoints. The Government of Ghana initiated a major effort to put environmental issues on the priority agenda in March 1988. This led to the preparation of an Environmental Action Plan (EAP) in 1991 to address issues relating to the protection of the environment, but the need is still urgent to adopt relevant population policies as a basic strategy in sustainable development.

Examining domains of community health nurse satisfaction and motivation: results from a mixed-methods baseline evaluation in rural Ghana.

Science.gov (United States)

Sacks, Emma; Alva, Soumya; Magalona, Sophia; Vesel, Linda

2015-10-08

A strong health system requires a competent and caring workforce. A more satisfied and motivated health workforce should be more willing to serve in difficult areas, have lower turnover, and theoretically provide better care to patients. This paper examines the motivation, satisfaction, and correlation with clinical knowledge, of community health nurses (CHNs), a cadre of provider focused on maternal, newborn and child health in rural Ghana. This study employed three methods of evaluation. Two quantitative measurements were used: (1) a survey of health worker satisfaction and motivation and (2) a clinical knowledge assessment focusing on maternal, newborn and child health. Both were administered to all rostered CHNs working in the five sampled districts in the Greater Accra and Volta regions in Eastern Ghana (N = 205). Qualitative interviews (N = 29) and focus group discussions (N = 4) were held with selected CHNs in the same districts. These data were analysed using NVivo (Version 10) and Stata (Version 13.0) based on domains of extrinsic and intrinsic motivation including general satisfaction, work environment and access to resources, respect and recognition received and opportunities for advancement. CHNs desired more training, especially those who were posted at the community level (a Community-based Health Planning and Services post or "CHPS") versus at a health facility. CHNs working at CHPS believed their work to be more difficult than those posted at health facilities, due to challenges associated with foot travel to visit patients at home, and they were more likely to report having insufficient resources to do their jobs (48% vs 36%). However, CHNs posted at health facilities were more likely to report insufficient opportunities for career advancement than the CHPS nurses (49% vs 33%). CHNs generally reported good relationships with colleagues and being respected by patients but desired more respect from supervisors. The median score on the

Drawing on discursive psychology and positioning theory, this study explores the influence of cultural and familial value orientations on battered women’s identity, agency and decision to leave or stay in abusive conjugal relationship in Ghana. Two semi-structured focus group discussions and four...... in-depth personal interviews were conducted with 16 victims of husband-to-wife abuse from rural and urban Ghana. The findings indicate that entrapment of victims of spousal abuse in Ghana reflects their social embeddedness and that battered women’s identities and agency are expressed in the context...... of familial and cultural value orientations. The primacy of family identity and victims’ apparent implicit moral obligation to preserve the social image of their extended family influence their entrapment. Participants’ discursive accounts further suggest that stay/leave decisions of battered women in Ghana...

As such, this study sought to examine the sociodemographic factors that determine malaria among under-five children in Ghana. Methods. This paper used secondary data drawn from the 2008 Ghana Demographic and Health Survey. Bivariate analysis and complementary log-log regression models were used to examine the determinants of malaria prevalence among under-five children in Ghana for the study period. Results. The results therefore revealed that region of residence, age of child, and ownership of mosquito net were the key predictors of malaria cases among under-five children in Ghana for the five-year period preceding the survey. Conclusion. It is therefore imperative that special education on prevention of malaria should be intensified by the National Malaria Control Programme in all the regions in order to reduce malaria prevalence particularly among under-five children in Ghana.

We have provided evidence of causes of low-skilled birth attendance in Ghana. Physical accessibility of health care, sociocultural factors, economic factors and health care system delivery problems were found as the main underlying causes of low levels of skilled birth attendance in Ghana. The paper provides potential strategies in addressing maternal and child health issues in Ghana.

Dietary diversity and child malnutrition in Ghana

Directory of Open Access Journals (Sweden)

Raymond Boadi Frempong

2017-05-01

Full Text Available The health of children in Ghana has improved in recent years. However, the current prevalence rates of malnutrition remain above internationally acceptable levels. This study, therefore, revisits the determinants of child health by using Ghana’s Multiple Indicator Cluster Survey to investigate the effect of infant feeding practices on child health. We used the World Health Organization’s Infant and Young Children Feeding guidelines to measure dietary quality. The econometric analyses show that dietary diversity may cause improvement in children’s health in Ghana. This suggests that educational campaigns on proper infant feeding and complementary dieting could be an effective means of improving the health of children in Ghana.

Although the use of radioisotopes in Ghana began in 1952, the Radiation Protection Board of Ghana was established in 1993 and served as the national competent authority for authorization and inspection of practices and activities involving radiation sources until 2015. The law has been superseded by an Act of Parliament, Act 895 of 2015, mandating the Nuclear Regulatory Authority of Ghana to take charge of the regulation of radiation sources and their applications. The Radiation Protection Institute in Ghana provided technical support to the regulatory authority. Regulatory and service activities that were undertaken by the Institute include issuance of permits for handling of a radiation sources, authorization and inspection of radiation sources, radiation safety assessment, safety assessment of cellular signal towers, and calibration of radiation-emitting equipment. Practices and activities involving application of radiation are brought under regulatory control in the country through supervision by the national competent authority.

Smoking in Ghana: a review of tobacco industry activity.

Owusu-Dabo, E; Lewis, S; McNeill, A; Anderson, S; Gilmore, A; Britton, J

2009-06-01

African countries are a major potential market for the tobacco industry, and the smoking epidemic is at various stages of evolution across the continent. Ghana is an African country with a low prevalence of smoking despite an active tobacco industry presence for over 50 years. This study explores potential reasons for this apparent lack of industry success. To explore the history of tobacco industry activity in Ghana and to identify potential reasons for the current low prevalence of smoking. A search was made of tobacco industry archives and other local sources to obtain data relevant to marketing and consumption of tobacco in Ghana. British American Tobacco, and latterly the International Tobacco Company and its successor the Meridian Tobacco Company, have been manufacturing cigarettes in Ghana since 1954. After an initial sales boom in the two decades after independence in 1957, the sustained further increases in consumption typical of the tobacco epidemic in most countries did not occur. Possible key reasons include the taking of tobacco companies into state ownership and a lack of foreign exchange to fund tobacco leaf importation in the 1970s, both of which may have inhibited growth at a key stage of development, and the introduction of an advertising ban in 1982. BAT ceased manufacturing cigarettes in Ghana in 2006. The tobacco industry has been active in Ghana for over 50 years but with variable success. The combination of an early advertising ban and periods of unfavourable economic conditions, which may have restricted industry growth, are likely to have contributed to the sustained low levels of tobacco consumption in Ghana to date.

Três espécimes de Anopheles darlingi Root foram encontrados na reserva ambiental Volta Grande, na área de influência da barragem do Rio Grande construída pela usina hidrelétrica de Volta Grande, em Conceição das Alagoas, Minas Gerais, Brasil. O mosquito An. darlingi é um dos principais vetores da malária humana no Brasil, devido à sua preferência alimentar por sangue humano, um fator que é acentuado pelo comportamento endofílico da espécie. O presente relato poderá ser útil à vigilância entomológica local para monitoramento dos impactos gerados pela formação do reservatório hidrelétrico, uma vez que a presença deste vetor neste tipo de ambiente indica um risco potencial de transmissão da malária.

Reproductive health laws and fertility decline in Ghana.

Science.gov (United States)

Finlay, Jocelyn E; Fox, Ashley M

2013-11-01

An unresolved debate in demography concerns the causal sequence between the supply of contraception and the demand for smaller families in fertility decline. Through a mixed-methods approach, we explored the effect of a sudden increase in access to legal abortion on subsequent fertility decline when Ghana's criminal code was amended in 1985. Using Ghana Demographic and Health Surveys, we constructed a panel of women aged 15-34 years and undertook a spline regression analysis to examine the effect of legal changes in 1985 and fertility decline controlling for social determinants of fertility. In addition, we conducted 17 key informant interviews (KIIs) to understand the reasons for the legal change and competing explanations for fertility decline. Multivariate results indicated that the timing of the liberalization of the abortion law coincided with the onset of Ghana's fertility decline. The KIIs indicated that the reasons for the liberalization of reproductive health laws were in response to famine and physician advocacy. While the timing of the abortion law liberalization coincided with the fertility decline in Ghana, we are unable to decouple the effect of the legal change from the effects of a severe famine that affected the region at the same time. Further research on documented and undocumented abortion in Ghana should be conducted to validate the contribution of legal abortion to fertility decline. © 2013.

International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Ghana. Draft

Guelpa, Jean-Paul; Vogel, Wolfram

1982-12-01

The Republic of Ghana has no claimed uranium resources in the categories Reasonably Assured and Estimated Additional. The only occurrences known are within pegmatites and are of no economic importance. The IUREP Orientation Phase Mission to Ghana estimates that the Speculative Resources of the country fall between 15,000 and 40,000 tonnes uranium. The IUREP Orientation Phase Mission to Ghana believes that the Panafrican Mobile Belt has the highest uranium potential of all geological units of the country. The Obosum beds are the priority number two target. A three years exploration programme is recommended for a total cost of US $ 5,000,000. The Ghana Atomic Energy Commission and the Ghana Geological Survey provide a basic infrastructure for uranium exploration. Any future uranium development in Ghana should be embedded in a well defined national uranium policy. It is recommended that such a policy be draw, up by the Ghanaian authorities

National waste management infrastructure in Ghana

International Nuclear Information System (INIS)

Darko, E.O.; Fletcher, J.J.

1998-01-01

Radioactive materials have been used in Ghana for more than four decades. Radioactive waste generated from their applications in various fields has been managed without adequate infrastructure and any legal framework to control and regulate them. The expanded use of nuclear facilities and radiation sources in Ghana with the concomitant exposure to human population necessitates effective infrastructure to deal with the increasing problems of waste. The Ghana Atomic Energy Act 204 (1963) and the Radiation Protection Instrument LI 1559 (1993) made inadequate provision for the management of waste. With the amendment of the Atomic Energy Act, PNDCL 308, a radioactive waste management centre has been established to take care of all waste in the country. To achieve the set objectives for an effective waste management regime, a waste management regulation has been drafted and relevant codes of practice are being developed to guide generators of waste, operators of waste management facilities and the regulatory authority.

2007-01-01

Full Text Available Abstract Background This article describes a survey of health workers and traditional birth attendants (TBAs which was carried out in 2005 in two regions of Ghana. The objective of the survey was to ascertain the impact of the introduction of a delivery fee exemption scheme on both health workers and those providers who were excluded from the scheme (TBAs. This formed part of an overall evaluation of the delivery fee exemption scheme. The results shed light not only on the scheme itself but also on the general productivity of a range of health workers in Ghana. Methods A structured questionnaire was developed, covering individual and household characteristics, working hours and practices, sources of income, and views of the exemptions scheme and general motivation. After field testing, this was administered to 374 respondents in 12 districts of Central and Volta regions. The respondents included doctors, medical assistants (MAs, public and private midwives, nurses, community health nurses (CHNs, and traditional birth attendants, both trained and untrained. Results Health workers were well informed about the delivery fee exemptions scheme and their responses on its impact suggest a realistic view that it was a good scheme, but one that faces serious challenges regarding financial sustainability. Concerning its impact on their morale and working conditions, the responses were broadly neutral. Most public sector workers have seen an increased workload, but counterbalanced by increased pay. TBAs have suffered, in terms of client numbers and income, while the picture for private midwives is mixed. The survey also sheds light on pay and productivity. The respondents report long working hours, with a mean of 54 hours per week for community nurses and up to 129 hours per week for MAs. Weekly reported client loads in the public sector range from a mean of 86 for nurses to 269 for doctors. Over the past two years, reported working hours have been

E-waste interventions in Ghana.

Science.gov (United States)

Asante, Kwadwo Ansong; Pwamang, John A; Amoyaw-Osei, Yaw; Ampofo, Joseph Addo

2016-03-01

Electrical and electronic waste (e-waste) has become an emerging environmental and human health problem in the world in the 21st century. Recently, the developing nations of West Africa (e.g. Ghana and Nigeria) have become a major destination for e-waste worldwide. In Ghana, the e-waste recyclers use primitive methods (mechanical shredding and open burning) to remove plastic insulation from copper cables. This technique can release highly toxic chemicals and severely affect the environment and human health if improperly managed. It is as a result of the adverse impact on human health that some interventions are being made in Ghana to reduce exposure. The present mode of recycling/dismantling, which happens at Agbogbloshie must be replaced by official receiving/recycling centers to be established. Currently, equipment to strip both large and small cables are available in the country via the Blacksmith Institute (USA) and it is expected that the e-waste workers will embrace the use of these machines. This technology will go a long way to help prevent the burning of e-waste and will be replicated in other smaller e-waste centers in the country.

ASSESSMENT OF LOGISTICS MANAGEMENT IN GHANA HEALTH SERVICE

Directory of Open Access Journals (Sweden)

2013-08-01

Full Text Available Ghana Public Health Sector runs a three-tier system of managing health commodities. Suppliers, the Central Medical Store, The Regional Medical Store, Service Delivery Points and the transportation system form the supply chain.  Ghana Health Service logistics system is centralized and the health care delivery system is decentralized. Logistics management in the health system is crucial. This is because there are instances where medicines and health commodities are not available at the Central Medical Stores and the Regional Medical Stores. Consequently, there is no commodity security at the service delivery points. Upon this backdrop the study seeks to assess the logistics management system in order to bring efficiency in the system. The study adopts a multi-case study approach to assess the practices of logistics management, the causes of inadequacy of logistics and the strengths and weaknesses in Ghana Health Service logistics system.  Two categories of participants that is, the key players of health logistics management and end-users were involved in the study.  Four variables; finance for procurement of health commodities, evenly distribution of health commodities, effective supervision and constant monitoring and evaluation were found crucial in effective and efficient logistics management. Moreover, it was found that poor procurement planning and budgeting, lack of financial resources for procurement, poor quantification and forecasting, delay in procurement process and order processing, and delay in receiving insurance claims are some of the causes of inadequacy of logistics in the health systems. It is recommended that Ghana Health Service logistics or supply system must receive constant monitoring and evaluation. Further, Ghana Health Service must ensure that there is effective top-down supervision in the system to bring up efficiency. Again, Ghana Health Service and Ministry of Health must ensure enough funds are secured from the

Small Scale Foundries in Ghana: The challenges

Directory of Open Access Journals (Sweden)

Anthony ANDREWS

2012-08-01

Full Text Available Small Scale Foundries (SSFs have been in existence for several years in Ghana. The industry has created several jobs for the people of Ghana and has minimized the burden on government to find ways of disposing scrap metals generated within the country. While scrap metals are still being exported, the quantity exported has decreased as a result of recycling by foundrymen in producing various parts. The government of Ghana has not paid special attention to this industry. Nevertheless, individuals and private investors are heavily involved in producing several thousands of tonnes of castings annually generating revenue for the government through taxation as well as helping with metal waste disposal. Metal cast products are sold both locally and internationally to neighbouring countries. The industry is however faced with numerous challenges. These include quality issues due to lack of technical know-how, access to funding from both government and private financial institutions and foundry waste management. To promote this industry, government and private financial institutions must be encouraged to come on board. Policies must be established and proper training programme developed to improve and promote this technology. This could go a long way in reducing the high unemployment rate in Ghana.

Biomass is the major energy source in Ghana contributing about 64% of Ghana's primary energy supply. In this paper, an assessment of biomass resources and biofuels production potential in Ghana is given. The broad areas of energy crops, agricultural crop residues, forest products residues, urban wastes and animal wastes are included. Animal wastes are limited to those produced by domesticated livestock. Agricultural residues included those generated from sugarcane, maize, rice, cocoa, oil palm, coconut, sorghum and millet processing. The urban category is subdivided into municipal solid waste, food waste, sewage sludge or bio-solids and waste grease. The availability of these types of biomass, together with a brief description of possible biomass conversion routes, sustainability measures, and current research and development activities in Ghana is given. It is concluded that a large availability of biomass in Ghana gives a great potential for biofuels production from these biomass resources. (author)

Causes of childhood blindness in Ghana: results from a blind school survey in Upper West Region, Ghana, and review of the literature.

Huh, Grace J; Simon, Judith; Grace Prakalapakorn, S

2017-06-13

Data on childhood blindness in Ghana are limited. The objectives of this study were to determine the major causes of childhood blindness and severe visual impairment (SVI) at Wa Methodist School for the Blind in Northern Ghana, and to compare our results to those published from other studies conducted in Ghana. In this retrospective study, data from an eye screening at Wa Methodist School in November 2014 were coded according to the World Health Organization/Prevention of Blindness standardized reporting methodology. Causes of blindness/SVI were categorized anatomically and etiologically, and were compared to previously published studies. Of 190 students screened, the major anatomical causes of blindness/SVI were corneal scar/phthisis bulbi (CS/PB) (n = 28, 15%) and optic atrophy (n = 23, 12%). The major etiological causes of blindness/SVI were unknown (n = 114, 60%). Eighty-three (44%) students became blind before age one year. Of four published blind school surveys conducted in Ghana, CS/PB was the most common anatomical cause of childhood blindness. Over time, the prevalence of CS/PB within blind schools decreased in the north and increased in the south. Measles-associated visual loss decreased from 52% in 1987 to 10% in 2014 at Wa Methodist School. In a blind school in northern Ghana, CS/PB was the major anatomical cause of childhood blindness/SVI. While CS/PB has been the most common anatomical cause of childhood blindness reported in Ghana, there may be regional changes in its prevalence over time. Being able to identify regional differences may guide future public health strategies to target specific causes.

Margaret Sraku-Lartey

2015-01-01

Full Text Available This paper makes a case for harnessing indigenous knowledge (IK for sustainable national development in Ghana. IK according to the World Bank is the basic component of any country’s knowledge system and it is upon this knowledge that scientific research builds. In Ghana the Government has recognized the need to harness IK for sustainable national development and has therefore incorporated it into the National Science, Technology and Innovation Development Programme. But there is no evidence however that scientific research in Ghana actually takes IK into consideration during the research process. This paper discusses the concept of indigenous knowledge, its relevance in scientific discourse and the need for harnessing it for national development in Ghana. A desk study was conducted using journal publications, research and technical reports, online databases and the internet. About sixty articles were analysed using the thematic synthesis method under the following broad headings: Importance of Indigenous knowledge, Indigenous forest foods, Indigenous medicines, IK and food security, the management and processing of IK and the protection of Indigenous Knowledge.The results of the study established the need to document the local knowledge using appropriate procedures and strategies. It also concludes by suggesting that IK in Ghana must be protected by law and integrated into formal science.

Ghana is said to be the first independent sub-Saharan African country outside South Africa to promote science education and the application of science in industrial and social development. It has long been recognized that many schools' science curricula extend the extracurricular activities of boys more than those of girls. In order to bridge this gap, efforts have been made to give girls extra assistance in the learning of science by exposing them to science activities through specific camps, road shows, exhibitions, and so on. The best known of such efforts is the Science, Technology, and Mathematics Education (STME) camps and clinics for girls, which started in Ghana 23 years ago. Since our attendance at the Third International Conference on Women in Physics in Seoul, Korea, a lot has been achieved to further improve female science education, and this credit goes to STME. The first female nuclear engineer from Ghana graduated from the University of Ghana in March 2010.

Drivers of Informal Sector Participation of Small and Medium Enterprise in Ghana

Directory of Open Access Journals (Sweden)

Mintah S.

2018-03-01

Full Text Available The informal sector of Ghana has been growing amidst the recent economic development in this country. The study investigated the drivers of informal sector participation by SMEs in Ghana and made use of a Chi-square statistical methodology to analyze the drivers of SME participation in the informal sector of Ghana. Analyses from the study showed that gender can be deemed as a driver for SME participation in the informal sector of Ghana. Gender was significant at 0.012 with registration of business enterprise and 0.055 with tax obligation of respondents. The educational level of SME operators had an impact on registration and tax obligation and therefore can be deemed as a driver of SME participation in the informal sector of Ghana. However, the level of education was insignificant to registration and tax obligation but had a strong correlation to these variables. The study also showed that women are more likely to participate in the informal sector of Ghana as compared to men and also that there is a high tendency of not paying tax among SME operators in the informal sector of Ghana. A very low educational level among SME participants was recorded with over 60% of the respondents not having any formal education. Based on the findings of the study, a country-wide research can be done to ascertain the socio-economic determinants of informal sector participation in Ghana. Also, the study highly recommends policies that can harness the usefulness of informal sector.

Foreign bank entry impacted domestic-owned banks in Ghana from 1975 to 2008

Full Text Available This article empirically examines the effects of foreign bank entry on the financial performance of Merchant Bank Ghana Limited and Ghana Commercial Banks Limited in Ghana from 1975 to 2008. The main result of the pooled regression was that foreign bank entry relatively increased domestic banks’ return on assets for the period 1992-2008; a period with a high influx of foreign banks into Ghana. This result supported the studies by Beck, Demirguc-Kunt, and Levine (2006 and Boldrin and Levine (2009 that found that foreign bank entry enhanced domestic banks profitability margins. The presence of foreign-owned banks was not detrimental to the financial performance of the domestic-owned banks in Ghana.

Next steps towards a Climate Innovation Centre in Ghana. Discussion Paper

2011-03-01

A climate innovation centre is an institution aimed at enabling development through catalysing climate technology research, development, market creation and policy. This discussion paper discusses the possibilities, considerations and next steps for a Climate Innovation Centre (CIC) in Ghana based on new insights within the government of Ghana, a mapping of climate innovation in Ghana, new developments in the international climate negotiations and other multilateral processes, and analysis conducted by ECN. The conclusion is that a Climate Innovation Centre can fill significant gaps in climate resilient development in Ghana. It seems important that a Ghana CIC does not become yet another institution that focuses on basic research in the area of climate change. Rather, it should connect the dots of the Ghanaian climate innovation system and act as a knowledge facilitator, also for the private sector. Various models of climate innovation centres exist. Before choices are made for a model or a combination of models for Ghana, it is recommended to allow for a broad stakeholder process. The World Bank's infoDev programme could be a model for such a process. Such stakeholder engagement should be aligned with other policymaking processes on adaptation and low-carbon development, as well as related policy arenas, such as agriculture, transport, waste and energy.

Ghana's Integrated Nuclear Security Support Plan

International Nuclear Information System (INIS)

Dahlstrom, Danielle

2013-01-01

At the Korle Bu Teaching Hospital outside Accra, Pearl Lovelyn Lawson checks the records of the next patient to undergo radiotherapy and adjusts the dose settings of the teletherapy machine. It is business as usual at the facility that treats over fifty patients each day. But Lawson's routine now includes additional procedures to ensure that the highly radioactive cobalt-60 source located inside the machine remains secure. Nuclear security devices and systems such as double locks, motion sensors, and cameras that transmit images to a central alarm system have been installed to ensure that the source cannot be stolen, the facility sabotaged, or unauthorized access gained. At Korle Bu physical protection measures were upgraded as part of Ghana's Integrated Nuclear Security Support Plan (INSSP). Preventing, detecting and responding to criminal acts like the theft or illegal transfer of a radioactive source, is an international priority that could be addressed through an INSSP. As one of its key nuclear security services, the IAEA assists Member States in drafting such plans. An INSSP is developed jointly with the Member State, using a holistic approach to nuclear security capacity building. It reinforces the primary objective of a State's nuclear security regime to protect people, society, and the environment from the harmful consequences of a nuclear security event. Addressing five components - the legal and regulatory framework, prevention, detection, and sustainability - the jointly developed plan identifies the needs, responsible entities and organizations within the State, as well as the timeframe for the implementation of agreed nuclear security related activities. Ghana's INSSP, tailored to its specific needs, is based on findings and recommendations from advisory service missions carried out in Ghana, including an International Nuclear Security Advisory Service mission and an International Physical Protection Advisory Service mission. Ghana's INSSP was

Experience on domestic waste segregation in Ghana

Pollution from domestic wastes is a major environmental challenge in Ghana and many developing countries. Most of these countries depend almost entirely on landfills for waste management, which has proved to be expensive, inefficient and unsustainable. A sustainable solution to this problem is productive use of waste such as recycling. The main challenge that may limit recycling in Ghana and some of these countries is that a chunk of the wastes are littered on the environment, and the rest is...

Seismic activity in Ghana: past, present and future

Directory of Open Access Journals (Sweden)

P. E. Amponsah

2004-06-01

Full Text Available Though Ghana is far away from the major earthquake zones of the world, it is prone to earthquake disaster. Ghana has records of damaging earthquakes dating as far back as 1615. The last three major events occurred in 1862, 1906 and 1939. This paper presents the main historical and current instrumental recorded earthquakes of Ghana and the steps being taken to mitigate the negative effects of such disastrous occurrences in the country. The discussion is based on historical and current data obtained from the seismological observatories in Accra and Kukurantumi. Historical earthquakes of magnitude greater than 6.0 and current local tremors with magnitudes ranging from 1.0 to 4.8 on the Richter scale have been recorded since the establishment of the seismograph stations.

Approximately half of Ghana's overall population has access to electricity and, of this, much of it is in urban areas. Often in regions where modern energy is not available, kerosene lamps, for example, are used for indoor lighting. This produces harmful emissions, leading to poor respiratory effects. Implementation of hydrokinetic power (HKP) within nearby streams can provide low impact, robust energy to rural communities. Such a system lends itself to a simple design with ease of maintenance, which can be used as a stand alone power system (SAPS). With Ghana's renewable energy policies coming to fruition, it is sought to establish the economic viability and sustainability of this technology. This paper discusses site selection and the HKP technology in rural areas of Ghana. (author)

Glover, E.T.; Fletcher, J.J.

2000-01-01

The Ghana Atomic Energy Commission was established in 1963 by an Act of Parliament, Act 204 for the Promotion, Development and Peaceful Application of Nuclear Techniques for the Benefit of Ghana. As in many developing countries the use of nuclear application is growing considerably in importance within the national economy. The Radiation Protection Board was established as the national regulatory authority and empowered by the Radiation Protection Instrument LI 1559 (1993). The above regulations, Act 204 and LI 1559 provided a minimum legal basis for regulatory control of radioactive waste management as it deals with waste management issues in a very general way and is of limited practical use to the waste producer. Hence the National Radioactive Waste Management Centre was established in July 1995 to carry out waste safety operations in Ghana. This paper highlights steps that have been taken to develop a systemic approach for the safe management of radioactive waste in the future and those already in existence. (author)

Education and Health Care Policies in Ghana

Ziblim Abukari

2015-10-01

Full Text Available Education and health care policies in Ghana since independence have been universalist in approach providing free universal health care and free basic and tertiary education until the early 1980s. Precipitated primarily by a severe drought, stagnant economic growth, mismanagement, and political instability, Ghana undertook major economic reforms with prodding from the World Bank and International Monetary Fund in a bid to salvage the economy. These economic measures included cost recovery and cutback spending in education and health sectors. However, in recent years, purposive targeted interventions have been pursued to address inequalities in education and health care. These new programs include the Education Capitation Grant, school feeding program, and the National Health Insurance Scheme (NHIS, which are propelling Ghana toward the achievement of the Millennium Development Goals. The prospects of these programs in addressing disparities in access to education and health care in the country and recommendations for improved delivery are discussed.

The hazardous nature of small scale underground mining in Ghana

Directory of Open Access Journals (Sweden)

K.J. Bansah

2016-01-01

Full Text Available Small scale mining continues to contribute significantly to the growth of Ghana's economy. However, the sector poses serious dangers to human health and the environment. Ground failures resulting from poorly supported stopes have led to injuries and fatalities in recent times. Dust and fumes from drilling and blasting of ore present health threats due to poor ventilation. Four prominent small scale underground mines were studied to identify the safety issues associated with small scale underground mining in Ghana. It is recognized that small scale underground mining in Ghana is inundated with unsafe acts and conditions including stope collapse, improper choice of working tools, absence of personal protective equipment and land degradation. Inadequate monitoring of the operations and lack of regulatory enforcement by the Minerals Commission of Ghana are major contributing factors to the environmental, safety and national security issues of the operations.

Ghana and the Oil Sector: Beyond the Resource Curse?

International Nuclear Information System (INIS)

Pellerin, Mathieu

2015-09-01

Four years after the Jubilee block went into production, we can make an initial assessment of the governance of Ghana's oil resources. In terms of its institutional structure, Ghana is seen as a model for the entire continent. This structure is certainly not an empty shell and serves as an effective regulator for this strategic sector and, singularly, for the use of oil revenues. Although this framework clearly has its limitations, as highlighted in this paper, the balance sheet is a positive one and there have been notable improvements since 2011. The relative success of this governance is a direct consequence of Ghana's political maturity. This is evidenced by the preeminent role played by Parliament and civil society in formulating, implementing, monitoring and continuously improving this framework for governance. Conditions seem to be reunited for Ghana to transform its oil potential into opportunities for success. However, this is not the case, and this is due to economic obstacles as much as a Ghanaian sense of disillusion concerning oil exploitation and the benefits thereof. (author)

Ghana and Côte d’Ivoire: Changing Places

Directory of Open Access Journals (Sweden)

Markus Eberhardt

2010-03-01

Full Text Available The economic histories of Ghana and Côte d’Ivoire since their independence have been dramatically different. In the period from 1970 Ghana experienced a sustained collapse in its economy such that by 1983 its level of real GDP per person had fallen by some 40%, its currency was worthless and the third attempt at democratic government had ended with a fourth military coup in 15 years. In contrast, Côte d’Ivoire had enjoyed more or less uninterrupted growth such that by 1980 real GDP per person was twice its 1960s level. However, the period since the mid-1980s has seen a remarkable reversal of fortunes. From 1983 Ghana has experienced sustained recovery, while Côte d’Ivoire has seen large falls in income, its first coup in 1999 and a decline into civil war and ethnic unrest. From being among the least successful Ghana has gone to being among the most successful of African countries, changing places with Côte d’Ivoire which has seen its economy transformed from one experiencing rapid growth to stagnation in a country ravaged by a bitter civil war. This article seeks to document and explain this extraordinary reversal of fortunes.

Renewable energy consumption has been identified as a potential solution to the intermittent power supply in Ghana. Recently, a Renewable Energy Act has been passed which has a target of 10% of renewable energy component in Ghana's energy mix by 2020. Whilst effort is been made to enhance supply through feed in tariffs, education and tax reduction on renewable energy related equipment, there is the need to understand the drivers of renewable energy demand. In this study, the general unrestricted model through Autometrics is used to estimate the determinants of renewable energy demand in Ghana. The results indicate that both economic factors and non-economic affect the demand for renewable energy. In addition, the underlying energy demand trend exhibits energy using behaviour. The study recommends that economic factors such as consumer subsidies should be considered when promoting renewable energy demand.

Ashigbie, Paul G; Azameti, Devine; Wirtz, Veronika J

2016-01-01

Ghana established its National Health Insurance Scheme (NHIS) in 2003 with the goal of ensuring more equitable financing of health care to improve access to health services. This qualitative study examines the challenges and consequences of medicines management policies and practices under the NHIS as perceived by public and private service providers. This study was conducted in health facilities in the Eastern, Greater Accra and Volta regions of Ghana between July and August 2014. We interviewed 26 Key Informants (KIs) from a purposively selected sample of public and private sector providers (government and mission hospitals, private hospitals and private standalone pharmacies), pharmaceutical suppliers and NHIS district offices. Data was collected using semi-structured interview guides which covered facility accreditation, reimbursement practices, medicines selection, purchasing and pricing of medicines, and utilization of medicines. Codes for data analysis were developed based on the study questions and also in response to themes that emerged from the transcripts and notes. Most KIs agreed that the introduction of the NHIS has increased access to and utilization of medicines by removing cost barriers for patients; however, some pointed out the increased utilization could also be corollary to moral hazard. Common concerns across all facilities were the delays in receiving NHIS reimbursements, and low reimbursement rates for medicines which result in providers asking patients to pay supplementary fees. KIs reported important differences between private and public sectors including weak separation of prescribing and dispensing and limited use of drugs and therapeutic committees in the private sector, the disproportionate effects of unfavorable reimbursement prices for medicines, and inadequate participation of the private sector providers (especially pharmacies and licensed chemical sellers) in the NHIS. Health providers generally perceive the NHIS to have had a

Three extraordinary, historical documents stemming from observations made in 1697, 1803 and 1817 quote medicinal plant uses among the Fante, Ga and Ashanti people of present-day Ghana, and can be linked to original botanical specimens in European herbaria. This provides a unique opportunity to gain insight to the historical materia medica of Ghana and compare this to contemporary medicinal plant uses. By critical literary and taxonomic review, the present study (re-)establishes the earliest known history of many important Ghanaian medicinal plants, and assesses the scale of change and loss of medicinal plant knowledge in Ghana over time. The study provides the foundation to reconstruct lost or discontinued Ghanaian plant uses in local or ethnopharmacological contexts. Historical botanical specimens were located in the herbaria of University of Copenhagen Herbarium (C) and British Museum of Natural History (BM). The classification and synonymy of the specimens were updated for the study, and the historical vernacular names and medicinal uses of the plants compared with 20th/21st century literature. The plants of the historical Ga materia medica were (re-)collected to aid in semi-structured interviews. The interviews aimed to document the contemporary uses and names of the plants among the Ga, and to determine to what extent the historical medicinal uses and names are extant. The study identified 100 species in historical medicinal use in Ghana, which could be linked to 134 unique uses and 105 vernacular names in Twi (Ashanti/Fante) and Ga. Most of the plants are common in Ghana. At least 52% of the historical vernacular names appear to still be in use today. Of the specific historical uses, 41 (31%) were traced among contemporary medicinal plant uses in Ghana and represent some of the most important Ghanaian medicinal plant species. However, 93 (69%) of the historical uses could not be traced and appears to be discontinued or forgotten. Among the Ga, two medicinal

Full Text Available The study used logistic regression modelling to determine predictors of satisfaction with delivery of animal health care services for 889 clients (livestock and poultry keepers in periurban Ghana. Of the 15 indicators tested as predictors of satisfaction in this study, 8 were included in the best fit model. These were accessibility, availability of services, service charge, effectiveness, efficiency, quality of services, meeting client needs, and getting help. Efficiency and effectiveness were perceived by the respondents to be synonymous, as were service quality and effectiveness, as suggested by ORs>10 when cross tabulated. Therefore, one or the other could be used in future studies but not both to avoid collinearity. The identified predictors could be targeted for improvement in quality of service delivery to livestock and poultry keepers in Ghana.

Road transportation impact on Ghana's future energy and environment

Faah, George

2008-11-07

This research work explored the environmental and socio-economic benefits derived, if some proportion of daily passenger trips made using private cars in Ghana could be shifted to the use of public transport. The research applied the computer software COPERT III in estimating road transport Greenhouse gas (GHG) emissions and fuel consumption in Ghana for the base year 2005 and forecast years 2010 and 2020. The research reveals that if no major change occur in policies or economic determinants in meeting road transport and energy in Ghana, then the 2005 total emissions value is expected to rise by 36% in 2010 and over double in 2020 i.e. from 4.6 to 6.25 in 2010 and to 9.77 Mt CO{sub 2}e in 2020. However, if just 10% of daily passenger trips using private cars can be shifted towards the use of public transport, then the end results in reduction in emissions could earn Ghana about USD 6.6million/year under the Kyoto Protocol CDM initiative. The research also demonstrated that with a further 10% daily passenger trip shift, the outcome could be more promising, increasing to USD 13million/year. (orig.)

Pellerin, Mathieu

2011-12-01

After an indication of the main economic and social indicators of Ghana, and an overview of the historical evolution of Ghana towards democracy since its independence in 1960, a discussion of its advances and limitations in this respect as this country is starting oil production (support of investors, obstacles and difficulties related to institutional limits, decentralisation process, land tenure regime and tradition), the author discusses the possible consequences of this oil wind fall on the democratic dynamics, notably regarding the legal framework (issues of fragility of the institutional and legal systems). In a third part, the author discusses the capacity of the Ghanaian system to face the oil challenge while exorcising the generally occurring curse associated with oil resources

A simple replication of developed country applianceefficiency labels and standards is unlikely to be feasible in Ghana andmany other countries in Africa. Yet by creatively modifying the developedcountry appliance efficiency market transformation model, it should bepossible to achieve dramatic energy use reductions. As was true indeveloped countries in the previous two decades, refrigeration efficiencyimprovements provide the greatest energy savings potential in theresidential electricity sector in Ghana. Although Ghana, like manyAfrican countries may impose standards on imports since Ghana does nothave manufacturing facilities for appliances in country. This approachmay hurt some consumers who patronize a very diverse market of usedappliances imported from Europe. We discuss how meeting the challenges ofthe Ghanaian market will require modification of the usual energyefficiency labeling and standards paradigm. But once a refrigeratormarket transformation is accomplished in Ghana, we estimate an averageenergy savings potential of 550 kWh/refrigerator/year, and a monetarysavings of more than $35/refrigerator/year. We discuss how this modifiedrefrigerator efficiency market transformation may occur in the Ghanaiancontext. If successful, this market transformation is likely to be anexample for many other African countries.

Facts about Nuclear Waste Safety - How the issue is being treated in Ghana

International Nuclear Information System (INIS)

Glover, E.T.; Fletcher, J.J.

2001-01-01

The fear of radioactive discharges and releases particularly from severe nuclear accidents and radioactive waste is central to public concern about nuclear activities. This fear was witnessed when Ghana began to suffer shortage in electricity supply from the hydroelectric power station at Akosombo and debates began on Ghana's energy mix and alternate options. As in every country, dependable and continuous supply of electricity is a prerequisite for ensuring sustainable development. The Ghana Atomic Energy Commission was confronted at that time more than ever with the problem of public education on nuclear power safety to enhance public acceptance. This paper presents what the Ghana Atomic Energy Commission is doing to communicate facts and education about nuclear waste safety to the Ghanaian public and to facilitate the comparison of risk from nuclear reactors and disposal facilities with risks from other forms of technology. The paper also tells of the usefulness of and difficulties in using Jos Draiger and John Lakey's manual on Radiation and Radiation Protection to educate pupils in the Ghana Atomic Energy Commission Preparatory School. The difficulties in communication of facts about nuclear, radiation and waste safety in Ghana, because of the different languages and dialects used by Ghanaians in the rural areas of Ghana. As a large number of factors influence decision making in the energy sector. To assist energy planners, the Ghana Atomic Energy Commission carried out assessments of alternative energy sources, covering a broad range of technical, economic and environmental factors. Cost-benefit and risk-benefit analyses place the nuclear power option on a scale comparable to the other electricity generating technologies. How come then that nuclear power option has so much negative publicity? The conclusion is drawn that literacy in nuclear radiation and waste safety is needed at all levels of the Ghanaian society. As inadequate perception of radiation risk

Progressivity of health care financing and incidence of service benefits in Ghana.

2012-03-01

The National Health Insurance (NHI) scheme was introduced in Ghana in 2004 as a pro-poor financing strategy aimed at removing financial barriers to health care and protecting all citizens from catastrophic health expenditures, which currently arise due to user fees and other direct payments. A comprehensive assessment of the financing and benefit incidence of health services in Ghana was undertaken. These analyses drew on secondary data from the Ghana Living Standards Survey (2005/2006) and from an additional household survey which collected data in 2008 in six districts covering the three main ecological zones of Ghana. Findings show that Ghana's health care financing system is progressive, driven largely by the progressivity of taxes. The national health insurance levy (which is part of VAT) is mildly progressive while NHI contributions by the informal sector are regressive. The distribution of total benefits from both public and private health services is pro-rich. However, public sector district-level hospital inpatient care is pro-poor and benefits of primary-level health care services are relatively evenly distributed. For Ghana to attain an equitable health system and fully achieve universal coverage, it must ensure that the poor, most of whom are not currently covered by the NHI, are financially protected, and it must address the many access barriers to health care.

Ghana's electricity demand has been estimated to be growing at a high rate of about 7% per annum over the last ten years. This is due to the relatively high population growth, economic aspiration of the country and the extension of electricity to rural areas. Electricity supply, on the contrary, has been unable to meet the demand due to high dependency on rain-fed hydropower plants, which started operating in 1965 and currently account for about 68% of the total installed capacity. Within the last 28 years, climatic changes and draughts have caused the nation to experience three major power crises. These climate changes resulted in low inflows and thus reduced power generation from hydropower systems. To complement the hydropower systems, the Government in 1997 installed thermal plants based on light crude oil. However, due to the high crude oil prices on the international market in recent times have made the operation of these plants very expensive. Ghana's crude oil find can boost its energy supply when the oil exploration begins somewhere in 2010. For rural cooking, domestic biomass is employed. Ghana has no domestic coal resources. The Government of Ghana is concerned with: limited further growth potential of domestic hydro; high cost of imported oil and gas and environmental issues associated with use of imported coal. Small Solar and wind generation exist in some sectors, but potential large-scale development is not envisioned for the near future.

Highlights: • The wind energy and its economic viability along the coastal region of Ghana are examined. • Wind resource along the coastal region of Ghana fall into Class 2 or less wind resource. • Wind turbine with rated speed from 9 to 11 m/s is suggested for wind power development. • The unit cost of wind generated electricity is found be between 0.0732 GH¢/kW h and 0.2905 GH¢/kW h. - Abstract: This study examined the wind energy potential and the economic viability of using wind turbine for electricity generation in selected locations along the coastal region of Ghana. The two-parameter Weibull probability density function was employed to analyze the wind speed data obtained from the Ghana Energy Commission. The energy output and unit cost of electricity generated from medium size commercial wind turbine models with rated powers ranging from 50 kW to 250 kW were determined. It was found that the wind resource along the coastal region of Ghana can be classified into Class 2 or less wind resource which indicate that this resource in this area is marginally suitable for large scale wind energy development or suitable for small scale applications and be useful as part of hybrid energy system. It was further observed that wind turbine with designed cut-in wind speed of less than 3 m/s and moderate rated wind speed between 9 and 11 m/s is more suitable for wind energy development along the coastal region of Ghana. Based on the selected wind turbine and assumptions used in this study, it was estimated that the unit cost of electricity varied between 0.0695 GH¢/kW h and 0.2817 GH¢/kW h.

Full Text Available The study attempts to identify the macroeconomic factors responsible for inflation in Ghana for the period 1990 to 2009. For this purpose, the time series model is selected based on various diagnostic, evaluation and selection criteria. It can be concluded that the model has sufficient predictive powers and the findings are well in line with those of other studies. The research findings would show that real output and money supply are the strongest forces exerting pressure on the price level to move up the exchange rate depreciation and implementation of ERP helped reduce the level of inflation in Ghana giving evidence that the ERP achieved its basic objective of reducing inflationary trend in Ghana.

Socio-economic Inequalities and Healthcare Utilization in Ghana

Directory of Open Access Journals (Sweden)

2013-07-01

Full Text Available A socio-economic inequality in the use of healthcare services in Ghana is investigated in this paper. The data employed in the study were drawn from Global Ageing and Adult Health survey conducted in Ghana by SAGE and was based on the design for the World Health Survey (WHS, 2003. The survey was conducted in 2007 and collected data on socio-economic characteristics and other variables of the individuals interviewed. Using generalized logit model, the study found that health status is a very strong determinant of the type of healthcare services Ghanaians look for. In Ghana, there are still important socio-economic gradients in the use of some healthcare services. These differences may be due to socio-economic inequities but could also indicate that the existing health facilities are not always used in an optimal way. Patient factors may be more important than supply factors in explaining the differential use of health services.

Legislative instrument LI 1559 of 1993 established the Radiation Protection Board (RPB) as the National Competent Authority (NCA) on radiation matters in Ghana. The Board advises Government through the Ghana Atomic Energy Commission on matters relating to radiation safety, security of sources, sales, import and export, contamination in food and environment, among others. It has wide ranging regulatory power and works in association with country authorities. The regulations in place for controlling the movement and use of radioactive materials in Ghana are discussed. Accountability for radioactive materials especially for those which were brought in before the establishment of the RPB have been the focus of our discussion. The need to for intensify educational programs for the public on matters relating to effect of radiation on man and environment is recommended. Strengthening of regulatory control of sources and intensifying efforts against smuggling, unauthorised use and systems for notification on radioactive transport accidents are noted. (author)

The impact of household wealth on child survival in Ghana.

Lartey, Stella T; Khanam, Rasheda; Takahashi, Shingo

2016-11-22

Improving child health is one of the major policy agendas for most of the governments, especially in the developing countries. These governments have been implementing various strategies such as improving healthcare financing, improving access to health, increasing educational level, and income level of the household to improve child health. Despite all these efforts, under-five and infant mortality rates remain high in many developing nations. Some previous studies examined how economic development or household's economic condition contributes to child survival in developing countries. In Ghana, the question as to what extent does economic circumstances of households reduces infant and child mortality still remain largely unanswered. Thus, the purpose of this study is to investigate the extent to which wealth affects the survival of under-five children, using data from the Demographic and Health Survey (DHS) of Ghana. In this study, we use four waves of data from Demographic and Health Surveys (DHS) of Ghana from 1993 to 2008. The DHS is a detailed data set that provides comprehensive information on households and their demographic characteristics in Ghana. Data was obtained by distributing questionnaires to women (from 6000 households) of reproductive age between 15 and 49 years, which asked, among other things, their birth history information. The Weibull hazard model with gamma frailty was used to estimate wealth effect, as well as the trend of wealth effect on child's survival probability. We find that household wealth status has a significant effect on the child survival in Ghana. A child is more likely to survive when he/she is from a household with high wealth status. Among other factors, birth spacing and parental education were found to be highly significant to increase a child's survival probability. Our findings offer plausible mechanisms for the association of household wealth and child survival. We therefore suggest that the Government of Ghana

Prevalence and correlates of contraceptive use among female adolescents in Ghana.

Nyarko, Samuel H

2015-08-19

Adolescence is a critical stage in the life course and evidence suggests that even though contraceptive use has been steadily increasing among women in Ghana over the past years, contraceptive prevalence and determinants among female adolescents is quite lacking. This paper examines the prevalence and correlates of contraceptive use among female adolescents in Ghana. The paper used data from the 2008 Ghana Demographic and Health survey. Bivariate analysis was carried out to determine the contraceptive prevalence among female adolescents while logistic regression analysis was applied to examine the correlates of female adolescent contraceptive use. The study founded that female adolescent contraceptive use was significantly determined by age of adolescent, education, work status, knowledge of ovulatory cycle, visit of health facility and marital status. This has implications for adolescent sexual and reproductive health programmes in Ghana. It is therefore essential to intensify girl child education and strengthen the provision of family planning information and services for female adolescents in the country.

Social Factors Influencing Child Health in Ghana.

Directory of Open Access Journals (Sweden)

Emmanuel Quansah

Full Text Available Social factors have profound effects on health. Children are especially vulnerable to social influences, particularly in their early years. Adverse social exposures in childhood can lead to chronic disorders later in life. Here, we sought to identify and evaluate the impact of social factors on child health in Ghana. As Ghana is unlikely to achieve the Millennium Development Goals' target of reducing child mortality by two-thirds between 1990 and 2015, we deemed it necessary to identify social determinants that might have contributed to the non-realisation of this goal.ScienceDirect, PubMed, MEDLINE via EBSCO and Google Scholar were searched for published articles reporting on the influence of social factors on child health in Ghana. After screening the 98 articles identified, 34 of them that met our inclusion criteria were selected for qualitative review.Major social factors influencing child health in the country include maternal education, rural-urban disparities (place of residence, family income (wealth/poverty and high dependency (multiparousity. These factors are associated with child mortality, nutritional status of children, completion of immunisation programmes, health-seeking behaviour and hygiene practices.Several social factors influence child health outcomes in Ghana. Developing more effective responses to these social determinants would require sustainable efforts from all stakeholders including the Government, healthcare providers and families. We recommend the development of interventions that would support families through direct social support initiatives aimed at alleviating poverty and inequality, and indirect approaches targeted at eliminating the dependence of poor health outcomes on social factors. Importantly, the expansion of quality free education interventions to improve would-be-mother's health knowledge is emphasised.

Full Text Available This article describes on-going research on the development of a library strategy for universities in Ghana. The research focuses on the factors affecting the development of a strategic planning process aimed at improving the libraries' capacity to deliver information services effectively and efficiently. Since the structure of universities in Ghana is, to a great extent, derived from or modelled on that of universities in the United Kingdom the project of necessity also includes some consideration of current attitudes to the strategic planning process in a number of university libraries in the United Kingdom. It is hoped that the study and evaluation of this aspect of the management of United Kingdom university libraries may provide pertinent guidelines for university library management in Ghana.

Akortsu, Mercy Akosua; Abor, Patience Aseweh

2011-01-01

The financing of healthcare services has been of a major concern to all governments in the face of increasing healthcare costs. For developing countries, where good health is considered a poverty reduction strategy, it is imperative that the hospitals used in the delivery of healthcare services are well financed to accomplish their tasks. The purpose of this paper is to examine how public hospitals in Ghana are financed, and the challenges facing the financing modes adopted. To achieve the objectives of the study, one major public healthcare institution in Ghana became the main focus. The findings of the study revealed that the main sources of financing the public healthcare institution are government subvention, internally-generated funds and donor-pooled funds. Of these sources, the internally generated fund was regarded as the most reliable, and the least reliable was the donor-pooled funds. Several challenges associated with the various financing sources were identified. These include delay in receipt of government subvention, delay in the reimbursement of services provided to subscribers of health insurance schemes, influence of government in setting user fees, and the specifications to which donor funds are put. The findings of this study have important implications for improving the financing of public healthcare institutions in Ghana. A number of recommendations are provided in this regard.

A Descriptive Assessment of Higher Education Access, Participation, Equity, and Disparity in Ghana

Directory of Open Access Journals (Sweden)

Francis Atuahene

2013-07-01

Full Text Available Since independence, Ghana has comparatively distinguished itself among many Sub-Saharan African (SSA countries in its educational developments. Tertiary education in Ghana over the past decade has witnessed tremendous growth in various frontages—increased access and participation, relative expansion of academic facilities, a growing private sector, and most importantly, a transformative policy environment. Despite these overwhelming developments, there remain inequalities in the higher education system in Ghana: access has not been broadened to include all social groups. Available data suggest unequal participation among women, minorities, individuals from low socioeconomic backgrounds, and spatial-based disparities. Using enrollment data from universities, policy document from the Ministry of Education, and the National Council for Tertiary Education in Ghana, and academic research reports, the authors provide descriptive and critical analyses of the structures of inequalities and disparities in higher education in Ghana. The authors argue that in spite of the massive developments over the years, there exist accessibility and participation gap with respect to students’ socioeconomic status, gender, regions of origin, and the type and location of secondary schools attended.

Myiasis is the infestation of tissues of live vertebrate animals and humans with dipterous larvae. In sub-Saharan Africa, Cordylobia anthropohaga and Cordylobia rodhaini are known to be responsible for cutaneous myiasis in animals and humans. Human cases of myiasis, purportedly acquired in Ghana but diagnosed in other countries, have been reported; however, published data on its occurrence in animals in Ghana is unavailable. This study assessed the prevalence of canine myiasis among owned dogs in the Greater Accra region (GAR) of Ghana. A cross-sectional study was conducted in the Greater Accra region of Ghana, selected for being the region with the highest estimated population density of owned dogs. Physical examination and demographic characteristics of the study dogs were assessed. Management of the dogs was assessed through a questionnaire administered to the dog owners. A total of 392 owned dogs were sampled. Twenty-nine (7.4%) had cutaneous myiasis caused by C. rodhaini. In addition, one (0.2%) of the dogs had intestinal myiasis, with Dermatobia hominis as the offending larvae. Among the breeds of dogs with myiasis, the mongrel was most affected, with 24 (82.8%) out of the 29 cases. The mongrels, majority of which (24; 82.8%) were males, were left to roam freely in the community. Results from this study demonstrate that C. rodhaini and D. hominis are important causes of myiasis in owned dogs in the GAR of Ghana. Dogs could play a role in the spread of myiasis to humans, with its attendant public health implications.

This week, 220 servers and 30 routers were donated to the Kwame Nkrumah University of Science and Technology (KNUST) in Ghana.   “KNUST will provide a good home for these computers. The university has also developed a plan for using them to develop scientific collaboration with CERN,” said John Ellis, a professor at King’s College London and a visiting professor in CERN’s Theory Group.  John Ellis was heavily involved in building the relationship with Ghana, which started in 2006 when a Ghanaian participated in the CERN openlab student programme. Since 2007 CERN has hosted Ghanaians especially from KNUST in the framework of the CERN Summer Student Progr...

2014-01-01

Background The burden of maternal mortality in sub-Saharan Africa is enormous. In Ghana the maternal mortality ratio was 350 per 100,000 live births in 2010. Skilled birth attendance has been shown to reduce maternal deaths and disabilities, yet in 2010 only 68% of mothers in Ghana gave birth with skilled birth attendants. In 2005, the Ghana Health Service piloted an enhancement of its Community-Based Health Planning and Services (CHPS) program, training Community Health Officers (CHOs) as mi...

Nikoi, Ebenezer; Anthamatten, Peter

2013-01-01

The relationship between a child's environment and nutritional status is difficult to examine yet could offer an important guide to policy. The objective of the present work was to examine individual and environmental correlates with childhood height-for-age in Ghana. Data were derived from the 2008 MEASURE Demographic and Health Survey in Ghana, the 2000 Ghana Population and Housing Census, and the World Wide Fund for Nature's eco-regions database. A generalized linear mixed regression model was used to estimate the effects of individual and environmental correlates on height-for-age. The study examined 2225 Ghanaian children aged 0-59 months. The setting was all districts in Ghana for the year 2008. After accounting for individual characteristics of children, mothers and households, height-for-age was significantly associated with population density. Other significantly associated variables in the final model were the age of the child, vaccination status, the size of the child at birth, months of breast-feeding, mother's BMI, whether the child's mother had health insurance and wealth quintile. In addition to a number of characteristics of the children and their households, the social milieu is important to understanding differences in height-for-age among children in Ghana. The biophysical environment was not associated with height-for-age.

Of the global total number of adolescents living with HIV in 2013, 83% reside in sub-Saharan Africa. The study aimed to identify facilitators of and barriers to antiretroviral treatment adherence among adolescents in Ghana. Methods: A cross-sectional qualitative study using semi-structured interviews for data collection was carried out among adolescents (aged 12–19 years at the adolescents HIV clinic at the Korle-Bu Teaching Hospital in Ghana. Predominantly open-ended questions relating to ART were used. Interviews were done until saturation. In total, 19 interviews were conducted. Analysis was done manually to maintain proximity with the text. Findings: The main facilitators were support from health care providers, parental support, patient’s knowledge of disease and self-motivation, patient’s perceived positive outcomes, and dispensed formulation. The identified barriers were patient’s forgetfulness to take medicines, perceived stigmatization due to disclosure, financial barriers, and adverse effects of ART. Support from health care workers was the most frequently mentioned facilitator, and patient’s forgetfulness and perceived

Nielsen, Per Sieverts; Næraa, Rikke; Karlsson, Kenneth

1996-01-01

Cooking is the main energy consuming activity in Ghana. This is mainly due to a generally low material standard of living, but also because the cooking process itself is energy inefficient. The fuel for cooking in Ghana is mainly biomass either in the form of wood, agricultural residues or charcoal....... An energy chain for the cooking process is established and the possible conservation options are surveyed in kitchen performance tests in Abodom in the tropical zone of Ghana. The energy consumption for the food preparation has been measured and energy saving options have been determined for some parts...... point has been reached. Most cooks tend to continue using a high heat supply even though it is not necessary. This process is often carried out without lid on the pot even though the use of lid will reduce the energy loss considerably. It is also concluded that the average fuelwood consumption in Abodom...

Adolescent girls in Ghana still face a number of challenges accessing reproductive/sexual health services despite efforts to improve their accessibility. This paper explores the key socio-demographic factors associated with contraceptive use amongst adolescent girls in Ghana using the 2008 Ghana Demographic and Health Survey (GDHS). Data from the 2008 GDHS was analyzed. Socio-demographic variables were selected to assess their interaction with contraceptive use. Multivariable regression analyses were performed. Odds ratios and confidence intervals were computed. Place of residence and marital status were the most important predictors of contraceptive use among sexually active adolescents. Rural residents were less likely to use contraceptives compared to urban residents (OR 0.32, CI 0.12-0.84, p = 0.021) as well as married respondents compared to their unmarried peers (OR 0.27, 95% CI 0.11-0.67, p = 0.005). The accessibility of reproductive/sexual health services needs to be improved and promoted in rural areas and among married adolescent women.

Ethics, culture and nursing practice in Ghana.

Donkor, N T; Andrews, L D

2011-03-01

This paper describes how nurses in Ghana approach ethical problems. The International Council of Nurses' (ICN) Code for Nurses (2006) that serves as the model for professional code of ethics worldwide also acknowledges respect for healthy cultural values. Using the ICN's Code and universal ethical principles as a benchmark, a survey was conducted in 2009 to ascertain how nurses in Ghana respond to ethical and cultural issues in their practice. The study was qualitative with 200 participant nurses. Data were obtained through anonymous self-administered questionnaires. Descriptive statistics were used to analyze the data. Nurses' approaches to ethical problems in Ghana do not always meet expectations of the ICN Code for Nurses. They are also informed by local ethical practices related to the institutional setting and cultural environment in the country. While some cultural values complemented the ICN's Code and universal ethical principles, others conflicted with them. These data can assist nurses to provide culturally competent solutions to ethical dilemmas in their practice. Dynamic communication between nurses and patients/clients, intentional study of local cultural beliefs, and the development of ethics education will improve the conformity between universal ethical standards and local cultural values. © 2011 The Authors.

1999-11-01

The survey was conducted as a part of the project 'Test and Research Project into the Drying of Food and Wood Products with Solar Heat'. The aim of the survey was to investigate the need for drying of food and wood in Ghana and the already existing experience on solar drying in order to form a basis for the initial decisions within the project concerning the location of three demonstration solar dryers for crops, fish and wood, which species to dry and the type of solar dryers. The project deals with transfer of knowledge in the field of drying of crops and wood and solar air heating systems from Denmark to Ghana. The aim of the survey was, therefore, also to give the Danish experts an impression of the conditions in Ghana in order to facilitate an appropriate design of the solar dryers. Three of the four Danish partners participated in the survey. The fourth Danish partner - the manufacturer of solar heating systems Aidt Miljoe - are already familiar with the conditions in Ghana due to an earlier project in Ghana. The survey was planed by the Energy Commission of Ghana, the Ghanaian partner and consultants: DENG, University of Science and Technology, Kumasi and Econkoad. The time schedules for the survey - one for crops/fish and one for wood - are found in Annex A. The schedules were very well prepared and the sites to visit were well chosen. The visits gave the Danish experts a good overview of the situation in Ghana in the field of post harvesting of crops, handling of fish, drying and manufacturing of wood and existing experience on solar drying. The schedules included a large variety of different information and impressions e.g. ranging from large sawmill to small carpenters and workshops. Despite tight schedules the consultants managed to stick very close to the time schedules shown in Annex A. (au)

The region of Volta Grande do Xingu River, in the state of Pará, presents several kinds of land use ranging from extensive cattle farming to agroforestry, and deforestation. Currently, the Belo Monte Hydroelectric Power Plant affects the region. We present a checklist of amphibians and reptiles of the region and discuss information regarding the spatial distribution of the assemblies based on results of Environmental Programmes conducted in the area. We listed 109 amphibian (Anura, Caudata, and Gymnophiona) and 150 reptile (Squamata, Testudines, and Crocodylia) species. The regional species richness is still considered underestimated, considering the taxonomic uncertainty, complexity and cryptic diversity of various species, as observed in other regions of the Amazon biome. Efforts for scientific collection and studies related to integrative taxonomy are needed to elucidate uncertainties and increase levels of knowledge of the local diversity.

Full Text Available Limnology is a border discipline between geography, hydrology and biology, and is also closely connected with other sciences, from it borrows research methods. Physical limnology (the geography of lakes, studies lake biotopes, and biological limnology (the biology of lakes, studies lake biocoenoses. The father of limnology is the Swiss scientist F.A. Forel, the author of a three-volume entitled Le Leman: monographie limnologique (1892-1904, which focuses on the geology physics, chemistry and biology of lakes. He was also author of the first textbook of limnology, Handbuch der Seenkunde: allgemeine Limnologie,(1901. Since both the lake biotope and its biohydrocoenosis make up a single whole, the lake and lakes, respectively, represent the most typical systems in nature. They could be called limnosystems (lacustrine ecosystems, a microcosm in itself, as the American biologist St.A. Forbes put it (1887.

Refrigerator efficiency in Ghana: Tailoring an appliance market transformation program design for Africa

2007-01-01

In some cases, a simple replication of developed country appliance efficiency labels and standards may not be completely feasible in Ghana, Africa. Yet by creatively modifying the developed country appliance efficiency market transformation model, it should be possible to achieve dramatic energy use reductions. As was true in developed countries in the previous two decades, refrigeration efficiency improvements provide the greatest energy savings potential in the residential electricity sector in Ghana. Although Ghana, like many African countries may impose standards on imports since Ghana does not have manufacturing facilities for appliances in country. This approach may hurt some consumers who patronize a very diverse market of used appliances imported from Europe. We discuss how meeting the challenges of the Ghanaian market will require modification of the usual energy efficiency labeling and standards paradigm. But once a refrigerator market transformation is accomplished in Ghana, we estimate an average energy savings potential of 550 kWh/refrigerator/year, and a monetary savings of more than $35/refrigerator/year. We discuss how this modified refrigerator efficiency market transformation may occur in the Ghanaian context. If successful, this market transformation is likely to be an example for many other African countries

2016-05-01

The fundamental goal of the Government of Ghana's development agenda as enshrined in the Growth and Poverty Reduction Strategy to grow the economy to a middle income status of US$1000 per capita by the end of 2015 could be met by increasing the labour force, increasing energy supplies and expanding the energy infrastructure in order to achieve the sustainable development targets. In this study, a multivariate co-integration analysis of the Kaya factors namely carbon dioxide, total primary energy consumption, population and GDP was investigated in Ghana using vector error correction model with data spanning from 1980 to 2012. Our research results show an existence of long-run causality running from population, GDP and total primary energy consumption to carbon dioxide emissions. However, there is evidence of short-run causality running from population to carbon dioxide emissions. There was a bi-directional causality running from carbon dioxide emissions to energy consumption and vice versa. In other words, decreasing the primary energy consumption in Ghana will directly reduce carbon dioxide emissions. In addition, a bi-directional causality running from GDP to energy consumption and vice versa exists in the multivariate model. It is plausible that access to energy has a relationship with increasing economic growth and productivity in Ghana.

Adinkrah, Mensah

2014-03-01

Homicide-suicide in the industrialized West has been studied for many years. Yet, only limited scholarly research currently exists on the subject in Africa and other non-Western societies. The aim of the present descriptive study was to investigate homicide-suicides in contemporary Ghana. A content analysis of homicide-suicide reports in a major Ghanaian daily newspaper during 1990 to 2009 was conducted. The results overwhelmingly support findings in the literature, suggesting that homicide-suicides are extremely rare events in Ghana. The overwhelming majority of reported homicide-suicides were committed by males, with females substantially more likely to be the homicide victims. The offenders and victims were generally of low socioeconomic status. Most homicide-suicides involved victims and offenders who were intimately acquainted as family members. The majority of cases involved men who killed their wives on suspicion of infidelity; the next largest category involved men who murdered wives who threatened divorce or separation. The principal homicide and suicide methods were shooting with firearms, hacking with machetes, and stabbing with knives. The findings of the study are discussed in relation to Ghana's patriarchal family system and ideology and present socioeconomic issues in the country. This study recommends further research on this subject in Ghana and other African countries. This is necessary to further an understanding of homicide-suicide as a phenomenon, as well as a necessary prelude to the development and implementation of effective preventive programs.

Monique Paiva de Campos

Full Text Available In Brazil, American visceral leishmaniasis (AVL is caused byLeishmania (Leishmania chagasi and its main vector isLutzomyia longipalpis. Cases of canine visceral leishmaniasis (CVL in non-endemic areas have been reported over the last few years throughout the country. The objective of this research note is to describe an autochthonous case of CVL that occurred in the municipality of Volta Redonda, state of Rio de Janeiro, an area where the disease is not endemic, alerting veterinarians and the scientific community to the expansion of this important zoonosis and advising veterinary practitioners on how to deal with a suspicion of CVL. Canine visceral leishmaniasis can be misdiagnosed within a broad spectrum of canine diseases based on clinical and laboratory findings. Therefore, knowledge of its clinical manifestations, specific and sensitive laboratory diagnostic tests and parasitological procedures are of the utmost importance for rapid confirmation and notification of a case, thus contributing directly to the control of a focus.

This study investigated the prevalence and incidence of Traditional (where a person in a position of power harasses a subordinate) and contra power sexual harassment, (where a subordinate is the harasser of authority figure) in medical schools in Ghana. among. Cross-sectional study. Four hundred and nine medical students from four medical schools in Ghana were interviewed. We also considered if academic and financial dependence would predict either traditional or contra power sexual harassment. We further investigated, whether women were more bothered by sexual harassment than men and the correlation between sexual harassment and health. Women were 61% more likely to be sexually harassed than men 39%. Sexual harassment negatively affects the victims' health outcome. We found that the traditional form of sexual harassment was prevalent in medical schools in Ghana and that academic dependence predicted attacks. In the first and second years, women at these institutions are more likely to be sexually harassed than men. Sexual harassment policies of medical school need to be widely circulated. The various medical schools should provide reporting procedures and counseling for victims. This paper would inform policy and research.

Road transportation impact on Ghana's future energy and environment

Faah, George

2008-11-07

This research work explored the environmental and socio-economic benefits derived, if some proportion of daily passenger trips made using private cars in Ghana could be shifted to the use of public transport. The research applied the computer software COPERT III in estimating road transport Greenhouse gas (GHG) emissions and fuel consumption in Ghana for the base year 2005 and forecast years 2010 and 2020. The research reveals that if no major change occur in policies or economic determinants in meeting road transport and energy in Ghana, then the 2005 total emissions value is expected to rise by 36% in 2010 and over double in 2020 i.e. from 4.6 to 6.25 in 2010 and to 9.77 Mt CO{sub 2}e in 2020. However, if just 10% of daily passenger trips using private cars can be shifted towards the use of public transport, then the end results in reduction in emissions could earn Ghana about USD 6.6million/year under the Kyoto Protocol CDM initiative. The research also demonstrated that with a further 10% daily passenger trip shift, the outcome could be more promising, increasing to USD 13million/year. (orig.)

Great attention is paid to the basis of the cooperation laid in Soviet period. The article also observes current tendencies of the bilateral relations, which are quite friendly and fruitful. Moscow regards the Republic of Ghana as a reliable, time-proven partner especially on international issues: the establishment of a more democratic polycentric world order, ensuring regional and strategic stability, disarmament, combating international terrorism and other global challenges and threats. Russia and Ghana provide each other mutual support in the election of representatives of the two countries in international organizations. Russia and Ghana also develop their cooperation in the field of security. The participation of USSR/Russia in foreign trade of Ghana is analyzed. The significant increase in the number of Ghanaian trade partners is indicated while the share of Great Britain decreases and the share of Asian, African and other states increases. In recent years, the favorable conditions for the development of Russian-Ghanaian trade and economic relations were created. The cooperation of the two countries also develops in the field of nuclear energy. The main bilateral visits between Ghana and Russia are examined in the article. The special attention is paid to the first meeting of the Russian-Ghanaian Inter-governmental commission on trade, economic, academic and technical cooperation took place in Moscow in October 2014.

Gastel, Barbara; Burdine, James N.; Russell, Leon H.

2014-01-01

In Ghana, as in many other developing countries, most science reporting is done by general reporters. However, few studies have investigated science reporting in such a situation. To understand better the dynamics of science reporting in such context, we surveyed 151 general reporters in Ghana. Respondents’ demographic characteristics resembled those found in studies elsewhere. Respondents perceived health professionals and scientists as very important sources of information for reporting science. There was an inverse correlation between journalism experience and the number of science feature stories reported in the past 12 months (p = .017). Most respondents indicated that science journalism training would motivate them to report science more. Likewise, most reported that easier access to research findings would do so. We identify characteristics of reporters, media, scientific, and training institutions that are important influences of Ghanaian reporters’ coverage of science. We provide recommendations for advancing science reporting in Ghana. PMID:25193967

Like many countries in sub-Saharan Africa, Ghana is faced with the simultaneous challenges of increasing its health workforce, retaining them in country and promoting a rational distribution of staff in remote or deprived areas of the country. Recent increases in both public-sector doctor and nurse salaries have contributed to a decline in international out-migration, but problems of geographic mal-distribution remain. As part of a research project on human resources in the Ghanaian health sector, this study was conducted to elicit in-depth views from nursing leaders and practicing nurses in rural and urban Ghana on motivations for urban vs rural practice, job satisfaction and potential rural incentives. In-depth interviews were conducted with 115 nurses selected using a stratified sample of public, private and Christian Health Association of Ghana (CHAG) facilities in three regions of the country (Greater Accra, Brong Ahafo and Upper West), and among 13 nurse managers from across Ghana. Many respondents reported low satisfaction with rural practice. This was influenced by the high workload and difficult working conditions, perception of being 'forgotten' in rural areas by the Ministry of Health (MOH), lack of professional advancement and the lack of formal learning or structured mentoring. Older nurses without academic degrees who were posted to remote areas were especially frustrated, citing a lack of opportunities to upgrade their skills. Nursing leaders echoed these themes, emphasizing the need to bring learning and communication technologies to rural areas. Proposed solutions included clearer terms of contract detailing length of stay at a post, and transparent procedures for transfer and promotion; career opportunities for all cadres of nursing; and benefits such as better on-the-job housing, better mentoring and more recognition from leaders. An integrated set of recruitment and retention policies focusing on career development may improve job satisfaction

This paper examines the highly contested and ongoing biotechnology (Bt) policy-making process in Ghana. We analyse media content on how Bt is viewed in the context of Ghana's parliamentary debate on the Plant Breeders Bill and within the broader public policy-making literature. This paper does not seek to take a position on Bt or the Bill, but to understand how policy actors influence the debate with political and scientific rhetoric in Ghana. The study reveals that in the midst of scientific uncertainties of Bt's potential for sustainable agriculture production and food security, policy decisions that encourage its future adoption are heavily influenced by health, scientific, economic, environmental and political factors dictated by different ideologies, values and norms. While locally pioneered plant breeding is visible and common in the Ghanaian food chain, plant breeding/GMOs/Bt from international corporations is strongly resisted by anti-GMO coalitions. Understanding the complex and messy nature of Bt policy-making is critical for future development of agricultural technology in Ghana and elsewhere.

Full Text Available Entrepreneurship has been found as an important driver of economic growth, productivity and social development; hence the need for entrepreneurial graduate is on the increase. Thus the purpose of this paper is to investigate the factors that impact on the entrepreneurial intentions of polytechnic students in Ghana. In the study a model was proposed and empirically tested on a sample of 228 polytechnic students in Ghana. In the model, entrepreneurial intention is taken as a function of educational, community and family supports. The result of the survey showed that all the support factors impacts on students entrepreneurial intentions. The findings of this study have important implications for those who formulate, deliver and evaluate educational policies in Ghana. Based on the findings policy makers may make changes to foster students interest in entrepreneurship.

Women, microcredit and family planning practices: a case study from rural Ghana.

Norwood, Carolette

2011-01-01

This paper examines the influence of informal banking club participation on family planning practices in rural Ghana. Research from Asia suggests that family planning practices are improved by club participation. This study examines this thesis in an African context, using rural Ghana as a case study. A sample of 204 women (19 years and older) was drawn from Abokobi village, Ghana. Multivariate analyses of direct, mediating and moderating effects of women’s demographic background characteristics, membership status and length, and women’s empowerment status as predictors of family planning practices are assessed. Findings suggest that club membership and membership length is not associated with family planning practices; however, age, education level, number of children and empowerment status are.

HIV antiretroviral medication stock-outs in Ghana: contributors and consequences.

Drug stock-outs are an unfortunate yet common reality for patients living in low and middle income countries, particularly in sub-Saharan Africa where trouble with consistent stock of antiretroviral medications (ARVs) continues. Our study takes a snapshot of this problem in Ghana. Although the country launched its antiretroviral therapy (ART) programme in 2003, progress toward realising the full benefit of ART for treated individuals has been limited, in part, because of stock-outs. In Ghana's Greater Accra region, we conducted semi-structured interviews with 40 women living with HIV (WLHIV) and 15 individuals with a history of HIV-related work in government or non-governmental organisations, or healthcare facilities. We used repeated review with coding and mapping techniques to analyse the transcripts and identify common themes. Stock-outs of ARVs result in inconsistent administration of therapy, increased indirect medical costs for WLHIV, and negative labelling of patients. Inefficiencies in drug supply, poor coordination with port authorities, inadequate government funding and dependence on international aid contribute to the stock-outs experienced in Ghana. Although using ARVs produced in-country could reduce supply problems, the domestically-manufactured product currently does not meet World Health Organization (WHO) standards. We recommend focused efforts to produce WHO standard ARVs in Ghana, and a review of current supply chain management to identify and mend pitfalls in the system.

The collection, analysis, and use of data to measure and improve immunization program performance are priorities for the World Health Organization (WHO), global partners, and national immunization programs (NIPs). High quality data are essential for evidence-based decision-making to support successful NIPs. Consistent recording and reporting practices, optimal access to and use of health information systems, and rigorous interpretation and use of data for decision-making are characteristics of high-quality immunization information systems. In 2015 and 2016, immunization information system assessments (IISAs) were conducted in Kenya and Ghana using a new WHO and CDC assessment methodology designed to identify root causes of immunization data quality problems and facilitate development of plans for improvement. Data quality challenges common to both countries included low confidence in facility-level target population data (Kenya = 50%, Ghana = 53%) and poor data concordance between child registers and facility tally sheets (Kenya = 0%, Ghana = 3%). In Kenya, systemic challenges included limited supportive supervision and lack of resources to access electronic reporting systems; in Ghana, challenges included a poorly defined subdistrict administrative level. Data quality improvement plans (DQIPs) based on assessment findings are being implemented in both countries. IISAs can help countries identify and address root causes of poor immunization data to provide a stronger evidence base for future investments in immunization programs.

Traditional medicine has been practised in Ghana for centuries with the majority of Ghanaians still patronising the services of traditional healers. Throughout Africa a large number of people use pangolins as a source of traditional medicine, however, there is a dearth of information on the use of animals in folk medicine in Ghana, in particular the use of pangolins. The aim of this study was to determine the prevalent use of pangolins and the level of knowledge of pangolin use among traditional healers in Ghana for the treatment of human ailments. Data was gathered from 48 traditional healers using semi-structured interviews on the traditional medicinal use of pangolin body parts in the Kumasi metropolis of Ghana. The cultural importance index, relative frequency of citation, informant agreement ratio and use agreement values were calculated to ascertain the most culturally important pangolin body part as well as the level of knowledge dissemination among traditional healers with regards pangolin body parts. Our study revealed that 13 body parts of pangolins are used to treat various medicinal ailments. Pangolin scales and bones were the most prevalent prescribed body parts and indicated the highest cultural significance among traditional healing practices primarily for the treatment of spiritual protection, rheumatism, financial rituals and convulsions. Despite being classified under Schedule 1 of Ghana's Wildlife Conservation Act of 1971 (LI 685), that prohibits anyone from hunting or being in possession of a pangolin, our results indicated that the use of pangolins for traditional medicinal purposes is widespread among traditional healers in Ghana. A study on the population status and ecology of the three species of African pangolins occurring in Ghana is urgently required in order to determine the impact this harvest for traditional medical purposes has on their respective populations as current levels appear to be unmonitored and unsustainable.

In Ghana, as in many other developing countries, most science reporting is done by general reporters. However, few studies have investigated science reporting in such a situation. To understand better the dynamics of science reporting in such context, we surveyed 151 general reporters in Ghana. Respondents' demographic characteristics resembled those found in studies elsewhere. Respondents perceived health professionals and scientists as very important sources of information for reporting science. There was an inverse correlation between journalism experience and the number of science feature stories reported in the past 12 months (p=.017). Most respondents indicated that science journalism training would motivate them to report science more. Likewise, most reported that easier access to research findings would do so. We identify characteristics of reporters, media, scientific, and training institutions that are important influences of Ghanaian reporters' coverage of science. We provide recommendations for advancing science reporting in Ghana. © The Author(s) 2014.

Market timing and selectivity performance of mutual funds in Ghana

2014-07-01

Full Text Available The growing interest in mutual funds in Ghana has been tremendous over the last decade as evidenced by the continuous increases in number and total funds under management. However, no empirical work has been done on the selectivity and timing ability of the mutual fund managers. Using monthly returns data hand-collected from the reports of the mutual fund managers for the period January 2007-December 2012, this paper examines the market timing and selectivity ability of mutual fund managers in Ghana using the classic Treynor-Mazuy (1966 model and Henriksson- Merton (1981 model. The results suggest that, in general mutual fund managers in Ghana are not able to effectively select stocks and also are not able to predict both the magnitude and direction of future market returns. More specifically, all of the sample mutual fund managers attain significant negative selectivity coefficients and also most of them attain insignificant negative timing coefficients.

Kin Group Affiliation and Marital Violence Against Women in Ghana.

Sedziafa, Alice Pearl; Tenkorang, Eric Y

2016-01-01

The socialization of men and women in Ghana often confers either patrilineal or matrilineal rights, privileges, and responsibilities. Yet, previous studies that explored domestic and marital violence in sub-Saharan Africa, and Ghana, paid less attention to kin group affiliation and how the power dynamics within such groups affect marital violence. Using the 2008 Ghana Demographic and Health Survey and applying ordinary least squares (OLS) techniques, this study examined what influences physical, sexual, and emotional violence among matrilineal and patrilineal kin groups. Results indicate significant differences among matrilineal and patrilineal kin groups regarding marital violence. Socioeconomic variables that capture feminist and power theories were significantly related to sexual and emotional violence in matrilineal societies. Also, variables that tap both cultural and life course epistemologies of domestic violence were strongly related to physical, sexual, and emotional violence among married women in patrilineal kin groups. Policymakers must pay attention to kin group affiliation in designing policies aimed at reducing marital violence among Ghanaian women.

Inguinal hernia is thought to be common in rural Ghana, though no recent data exist on hernia prevalence in the country. This information is needed to guide policy and increase access to safe hernia repair in Ghana and other low-resource settings. Adult men randomly selected from the Barekese sub-district of Ashanti Region, Ghana were examined by surgeons for the presence of inguinal hernia. Men with hernia completed a survey on demographics, knowledge of the disease, and barriers to surgical treatment. A total of 803 participants were examined, while 105 participants completed the survey. The prevalence of inguinal hernia was 10.8 % (95 % CI 8.0, 13.6 %), and 2.2 % (95 % CI 0, 5.4 %) of participants had scars indicative of previous repair, making the overall prevalence of treated and untreated inguinal hernia 13.0 % (95 % CI 10.2, 15.7 %). Prevalence of inguinal hernia increased with age; 35.4 % (95 % CI 23.6, 47.2 %) of men aged 65 and older had inguinal hernia. Untreated inguinal hernia was associated with lower socio-economic status. Of those with inguinal hernia, 52.4 % did not know the cause of hernia. The most common reason cited for failing to seek medical care was cost (48.2 %). Although inguinal hernia is common among adult men living in rural Ghana, surgical repair rates are low. We propose a multi-faceted public health campaign aimed at increasing access to safe hernia repair in Ghana. This approach includes a training program of non-surgeons in inguinal hernia repair headed by the Ghana Hernia Society and could be adapted for use in other low-resource settings.

Full Text Available The grounds underpinning companies resorting to different Corporate Social Responsibility (CSR practices are not obvious. Rationally, the profit making motive is at the front position of the companies’ goals as well as other factors which are hidden. This has led to a keen interest in promoting CSR among companies in Ghana than it was before. Through observations, document analysis and conduction of interviews of managers among the selected organizations, this paper sought to examine the CSR policies of five companies in Ghana and the associated benefits enjoyed by Ghanaians. Specifically, the paper aimed at determining the nature and impact – present and potential - of the selected companies’ CSR policies in Ghana and examined the assumptions behind the practice of CSR among the chosen companies. The methods used comprised primary data and secondary data sources. Convenient sampling technique was used for the study. The data were collected, collated and analyzed using charts and diagrams for easy interpretation. It was revealed from the research that, CSR programmes were community-focus initiatives, programmes on education as well as programmes in developing communities. It was therefore concluded that, there should be a law on CSR in Ghana and a course on CSR to train experts in that area.

Assessment of formaldehyde levels in local and imported fresh fish in Ghana: a case study in the Tamale Metropolis of Ghana.

Fish is an important source of protein all over the world, including in Ghana. The fishery sector plays a major role in meeting the domestic need of animal protein and also contributes greatly in foreign exchange earnings. The domestic supply of fish does not meet the demand, so Ghana imports fish and fish products from other countries. Media reports in Ghana have alleged the use of formaldehyde to preserve fish for increased shelf life and to maintain freshness. This research, therefore, sought to establish the levels of formaldehyde in imported and local fresh fish in the Tamale Metropolis by using a ChemSee formaldehyde and formalin detection test kit. Positive and negative controls were performed by using various concentrations of formalin (1, 10, 30, 50, 100, and 300 ppm) and sterile distilled water, respectively. Three times over a 6-month period, different fish species were obtained from five wholesale cold stores (where fish are sold in cartons) and some local sales points (where locally caught fish are sold). A total of 32 samples were taken during three different sampling sessions: 23 imported fish (mackerel, herring, horse mackerel, salmon, and redfish) and 9 local tilapia. The fish were cut, and 50 g was weighed and blended with an equal volume (50 ml) of sterile distilled water. Samples were transferred to test tubes and centrifuged. A test strip was dipped into the supernatant and observed for a color change. A change in color from white to pink or purple indicated the presence of formaldehyde in fish. The study showed that no formaldehyde was present in the imported and local fish obtained. The appropriate regulatory agencies should carry out this study regularly to ensure that fish consumed in Ghana is safe for consumption.

Rivers and effluents have been identified as major pathways for microplastics of terrestrial sources. Moreover, lakes of different dimensions and even in remote locations contain microplastics in striking abundances. This study investigates concentrations of microplastic particles at two lakes in central Italy (Lake Bolsena, Lake Chiusi). A total number of six Manta Trawls have been carried out, two of them one day after heavy winds occurred on Lake Bolsena showing effects on particle distribution of fragments and fibers of varying size categories. Additionally, 36 sediment samples from lakeshores were analyzed for microplastic content. In the surface waters 2.68 to 3.36 particles/m(3) (Lake Chiusi) and 0.82 to 4.42 particles/m(3) (Lake Bolsena) were detected, respectively. Main differences between the lakes are attributed to lake characteristics such as surface and catchment area, depth and the presence of local wind patterns and tide range at Lake Bolsena. An event of heavy winds and moderate rainfall prior to one sampling led to an increase of concentrations at Lake Bolsena which is most probable related to lateral land-based and sewage effluent inputs. The abundances of microplastic particles in sediments vary from mean values of 112 (Lake Bolsena) to 234 particles/kg dry weight (Lake Chiusi). Lake Chiusi results reveal elevated fiber concentrations compared to those of Lake Bolsena what might be a result of higher organic content and a shift in grain size distribution towards the silt and clay fraction at the shallow and highly eutrophic Lake Chiusi. The distribution of particles along different beach levels revealed no significant differences. Copyright © 2016 Elsevier Ltd. All rights reserved.

Mineral fertilizer is sparingly being used by smallholder farmers because of prohibitive cost. Grain legumes such as pigeonpea can play a complementary or alternative role as a source of organic fertilizer due to its ability to enhance soil fertility. Despite its importance, the potential of pigeonpea as a soil fertility improvement crop has not been exploited to any appreciable extent and the amount of land cultivated to pigeonpea in Ghana is vey negligible. This paper synthesizes recent studies that have been carried out on pigeonpea in Ghana and discusses the role of pigeonpea cultivation in soil fertility management and its implication for farming system sustainability. The paper shows that recent field studies conducted in both the semi-deciduous forest and the forest/savanna transitional agro-ecological zones of Ghana indicate that pigeonpea/maize rotations can increase maize yield by 75–200%. Barrier to widespread adoption of pigeonpea include land tenure, market, and accessibility to early maturing and high yielding varieties. The paper concludes among other things that in order to promote the cultivation of pigeonpea in Ghana, there is the need to introduce varieties that combine early maturity with high yields and other desirable traits based on farmers preferences.

Huang, Jingyu; Nkrumah, Philip Nti; Anim, Desmond Ofosu; Mensah, Ebenezer

2014-01-01

The volume of e-waste is growing around the world, and, increasingly, it is being disposed of by export from developed to developing countries. This is the situation in Ghana, and, in this paper we address the potential consequences of such e-waste disposal. Herein, we describe how e-waste is processed in Ghana, and what the fate is of e-waste-chemical contaminants during recycling and storage. Finally, to the extent it is known, we address the prospective adverse effects of e-waste-related contaminants on health and aquatic life downstream from a large e-waste disposal facility in Accra, Ghana.In developing countries, including Ghana, e-waste is routinely disassembled by unprotected workers that utilize rudimentary methods and tools. Once disassembled,e-waste components are often stored in large piles outdoors. These processing and storage methods expose workers and local residents to several heavy metals and organic chemicals that exist in e-waste components. The amount of e-waste dumped in Ghana is increasing annually by about 20,000 t. The local aquatic environment is at a potential high risk, because the piles of e-waste components stored outside are routinely drenched or flooded by rainfall, producing run-off from storage sites to local waterways. Both water and sediment samples show that e-waste-related contaminant shave entered Ghana's water ways.The extent of pollution produced in key water bodies of Ghana (Odaw River and the Korle Lagoon) underscores the need for aquatic risk assessments of the many contaminants released during e-waste processing. Notwithstanding the fact that pollutants from other sources reach the water bodies, it is clear that these water bodies are also heavily impacted by contaminants that are found in e-waste. Our concern is that such exposures have limited and will continue to limit the diversity of aquatic organisms.There have also been changes in the abundance and biomass of surviving species and changes in food chains. Therefore

Ghana's education reform 2007: A realistic proposition or a crisis of vision?

Science.gov (United States)

Kuyini, Ahmed Bawa

2013-07-01

Ghana's recent "Education Reform 2007" envisions a system that strives to achieve both domestic and internationally-oriented goals emanating (1) from the Education for All (EFA) initiative, (2) from the UN Convention on the Rights of the Child and (3) from global trends in education. Emboldened by the implementation of foreign-donor-funded programmes such as EFA, the restructuring of the Ghana Education Sector Project (EdSeP) and the Science Resource Centres (SRC) project, both the education reform of 2007 and recent educational policy debates have reiterated the need to emphasise the teaching of science and information and communication technology to make Ghana's students/graduates more competitive in the global labour market. However, the bulk of Ghana's economic activity actually remains domestic or unglobalised. And given a weak economy and declining social spending due to strict adherence to the prescribed structural adjustment policies of the International Monetary Fund (IMF) and the World Bank (WB), there is concern that a focus on international competitiveness may be a crisis of vision. On the basis of the Ghanaian government's failure to meet the stated goals of previous reforms such as that of 1974, and the education system's continuing dependence on foreign donor support, this paper argues that the goals of the new reform may be unachievable on a sustainable basis. It also argues that rather than subjugate national domestic priorities to a mirage of international credibility/competitiveness, Ghana should concentrate on capacitating her students/graduates to make maximum impact at domestic and local community levels.

SOMARC teams with private distribution firm to implement CSM program in Ghana.

Science.gov (United States)

1985-01-01

SOMARC, together with a private manufacturer and distributor of pharmaceutical products (Danafco, Limited), is launching a new contraceptive social marketing (CSM) program designed to make low cost, modern contraceptive products widely available in Ghana's cities. Danafco will directly implement the CSM program. Both the US Agency for International Development (USAID) and the government of Ghana will provide support to the program. James R. Kirland, USAID Population Officer, will assume overall responsibility for coordination and monitoring of CSM program activities. By a special amendment to the Pharmacy and Drug Act of 1961, the Ghanaian government has enabled the CSM program to conduct a demonstration project. Under the project, chemical sellers and retailers who successfully complete a special training session will be entitled to dispense oral contraceptives (OCs) without prescription. With the successful completion of this project, it is hoped that the Ghanaian government will further amend the Pharmacy Act to make contraceptives available nationwide on a nonprescription basis. Initially, the Ghana CSM program will market 3 products: a standard dosage OC; a foaming vaginal tablet; and an uncolored condom. Market research is now underway to determine product names for the OCs and vaginal tablets. The condom will be marketed under the name Panther. The project plans to conduct a retail audit to define current prices in the Ghanaian contraceptive market. Danafco will subcontract with Lintas Ghana Limited to provide advertising, package design, and promotion for the Ghana CSM program. Overall campaign efforts will focus on generating a positive climate for the program among influentials in government, religion, education, and health as well as consumers. The advertising campaign will include radio, television, print, and outdoor media. SOMARC, in collaboration with the USAID/Accra mission, hopes to establish an appropriate climate prior to the advertising launch

Where do overweight women in Ghana live? Answers from exploratory spatial data analysis

Directory of Open Access Journals (Sweden)

Fidelia A.A. Dake

2012-03-01

Full Text Available Contextual influence on health outcomes is increasingly becoming an important area of research. Analytical techniques such as spatial analysis help explain the variations and dynamics in health inequalities across different context and among different population groups. This paper explores spatial clustering in body mass index among Ghanaian women by analysing data from the 2008 Ghana Demographic and Health Survey using exploratory spatial data analysis techniques. Overweight was a more common occurrence in urban areas than in rural areas. Close to a quarter of the clusters in Ghana, mostly those in the southern sector contained women who were overweight. Women who lived in clusters where the women were overweight were more likely to live around other clusters where the women were also overweight. The results suggest that the urban environment could be a potential contributing factor to the high levels of obesity in urban areas of Ghana. There is the need for researchers to include a spatial dimension to obesity research in Ghana paying particular attention the urban environment.

2016-01-01

Full Text Available This paper examines the land tenure system in Ghana and its impact on the environment. The main forms of land tenure systems are explained and the positive and negative impacts of each of these forms on the environment analysed. Specific attention is devoted to deforestation and soil depletion. The complex problems of land acquisition in Ghana, and the inherent insecurity effects on farming, which is considered to be the most important economic activity in the rural areas are examined. The analyses and the result proved that the insecurity of land tenure system has a direct relationship with the environment. Cross-sectional data analyses establishes that traditional forms of land acquisitions, ownership and land use form part of the main causes of environmental degradation in Ghana.

1990-01-01

Chlorites related to propylitic phyllic processes in Fossil Hydrothermal System of Volta Grande/RS, quite similar to porphyry copper type deposit, were studied. Electron probe analysis in chlorites and chemical total rock analysis made the study of macro and micro system possible. The geochemical study of the micro system enable to characterize the inactive and active flow regimes of hydrothermal process in propylitic and phyllic, respectively. Geo-thermometric data, at least qualitatively, indicate that the phyllic alteration is the same or slightly higher than propylitic alteration. The detailed study of the composition of chlorites in micro system permitted to know the diadochic replacement of elements, especially in chloritization of biotite, in which the mobility of Al 3+ (at least in mineral scale) is possible under constant volume and Ti 4+ . The rocks were analysed by absorption spectroscopy, X-ray fluorescence analysis and gravimetry. (author)

Full Text Available In this study, we analyze interactions in lake and lake catchment systems of a continuous permafrost area. We assessed colored dissolved organic matter (CDOM absorption at 440 nm (a(440CDOM and absorption slope (S300–500 in lakes using field sampling and optical remote sensing data for an area of 350 km2 in Central Yamal, Siberia. Applying a CDOM algorithm (ratio of green and red band reflectance for two high spatial resolution multispectral GeoEye-1 and Worldview-2 satellite images, we were able to extrapolate the a(λCDOM data from 18 lakes sampled in the field to 356 lakes in the study area (model R2 = 0.79. Values of a(440CDOM in 356 lakes varied from 0.48 to 8.35 m−1 with a median of 1.43 m−1. This a(λCDOM dataset was used to relate lake CDOM to 17 lake and lake catchment parameters derived from optical and radar remote sensing data and from digital elevation model analysis in order to establish the parameters controlling CDOM in lakes on the Yamal Peninsula. Regression tree model and boosted regression tree analysis showed that the activity of cryogenic processes (thermocirques in the lake shores and lake water level were the two most important controls, explaining 48.4% and 28.4% of lake CDOM, respectively (R2 = 0.61. Activation of thermocirques led to a large input of terrestrial organic matter and sediments from catchments and thawed permafrost to lakes (n = 15, mean a(440CDOM = 5.3 m−1. Large lakes on the floodplain with a connection to Mordy-Yakha River received more CDOM (n = 7, mean a(440CDOM = 3.8 m−1 compared to lakes located on higher terraces.

ECONOMICS OF TOMATO MARKETING IN ASHANTI REGION, GHANA

Directory of Open Access Journals (Sweden)

Camillus Abawiera Wongnaa

2014-02-01

Full Text Available The perishable nature of most agricultural produce and the concomitant need for effective marketing outlets carries along huge economic consequences, especially in developing countries like Ghana. This study examines the determinants of profit in tomato marketing in the Ashanti Region of Ghana. Cross-sectional data collected from a random sample of 200 tomato marketers consisting of 100 wholesalers and 100 retailers were analyzed using descriptive statistics and the multiple linear regression technique of the ordinary least squares. The results show that wholesalers have a higher margin of 99.7 percent, while the retailers have a margin of 75.4 percent. Labour cost, purchase price, transportation cost and selling price run through all the estimated regressions as determinants of marketing profit. The effects of these variables on marketing profit could raise public concern since they have implications on prices received by tomato producers and those paid by final consumers and therefore there is the need for the government to devise policies aimed at stabilizing the local currency.The results also call for policy efforts to completely eliminate illiteracy among tomato traders in Ghana especially in the Ashanti Region. Policies that could enable the retailers to increase their scale of operations are also advocated. Future researchers may also estimate the exact point in the age variable at which retail profit declines and possible antecedents.

Two worlds apart: experiential learning in Ghana.

Science.gov (United States)

Ware, Sharon Douglass; Winters-Moorhead, Carol

2009-07-01

As our society becomes more diverse, it is important for nursing students to become culturally competent and to view the world from a global perspective. Traveling abroad enlightens the senses and expands the worldview. Traveling for study abroad is more than taking a vacation; it affords students the opportunity to learn experientially and it can be a transforming encounter that influences the way an evolving nurse will practice. Nursing students at North Carolina Central University in Durham, North Carolina, had the opportunity to bridge two worlds, urban life at the university and village life in Dodowa, Ghana, West Africa. The purpose of this article is to explore the role that studying abroad has in nurturing experiential learning. The experiences of students from a southern historically Black university that were enrolled concurrently in two summer independent study courses focusing on global healthcare in Ghana, West Africa, are described.

The Journey Towards Africanising Psychology in Ghana

Directory of Open Access Journals (Sweden)

Seth Oppong

2016-04-01

Full Text Available Psychology has come a long way since its origin in Africa and Ghana in particular. In this paper, an attempt is made to explore the current state of psychological knowledge in Ghana as well as the associated problems in the application of such knowledge. It was concluded that the approach to the study and application of psychological knowledge and tests has been too Eurocentric and westernized. As a result, it limits the applicability of the approach to the African setting, and yet, Western theorists may expect African psychologists to apply the theories to Africans. On the basis of this criticism, the scope of Pan-African psychology is defined and suggestions for pursuing an Africanisation project are presented. It is expected that the strategies that this paper advocates for indigenizing psychology in Africa can equally be useful to psychologists in other developing regions of the world.

A logistic regression model for Ghana National Health Insurance claims

Directory of Open Access Journals (Sweden)

Samuel Antwi

2013-07-01

Full Text Available In August 2003, the Ghanaian Government made history by implementing the first National Health Insurance System (NHIS in Sub-Saharan Africa. Within three years, over half of the country’s population had voluntarily enrolled into the National Health Insurance Scheme. This study had three objectives: 1 To estimate the risk factors that influences the Ghana national health insurance claims. 2 To estimate the magnitude of each of the risk factors in relation to the Ghana national health insurance claims. In this work, data was collected from the policyholders of the Ghana National Health Insurance Scheme with the help of the National Health Insurance database and the patients’ attendance register of the Koforidua Regional Hospital, from 1st January to 31st December 2011. Quantitative analysis was done using the generalized linear regression (GLR models. The results indicate that risk factors such as sex, age, marital status, distance and length of stay at the hospital were important predictors of health insurance claims. However, it was found that the risk factors; health status, billed charges and income level are not good predictors of national health insurance claim. The outcome of the study shows that sex, age, marital status, distance and length of stay at the hospital are statistically significant in the determination of the Ghana National health insurance premiums since they considerably influence claims. We recommended, among other things that, the National Health Insurance Authority should facilitate the institutionalization of the collection of appropriate data on a continuous basis to help in the determination of future premiums.

Techno-economic and environmental analysis of power generation expansion plan of Ghana

International Nuclear Information System (INIS)

Awopone, Albert K.; Zobaa, Ahmed F.; Banuenumah, Walter

2017-01-01

This paper examines the current electrical generation expansion plan of Ghana and compares it with proposed expansion pathways with higher penetration of Renewable Energy Technologies. An adaptation of Schwartz's Scenario Methodology was used to develop the scenarios which were then analysed using the Long-range Alternatives Planning (LEAP) model. Each of the scenarios represents policy options for generation expansion in Ghana up to 2040. Energy, economic and environmental analysis of the three alternative scenarios compared to the base scenarios was undertaken. Sensitivity results show that, if the country were to follow the generation expansion path described in the renewable energy scenarios, it could reap economic benefits of 0.5–13.23% depending on the developments in fuel prices and renewable technology capital cost. The analysis further quantifies benefits to be derived from a reduction in Greenhouse gases of the scenarios. Policy implications for the generation system of Ghana based on the results are also discussed. - Highlights: • LEAP demand projection for Ghana from 2010 to 2014. • Develop scenarios using an adaptation of Schwartz’s scenario approach. • Develop LEAP model for generation scenario. • Each scenario represents possible generation expansion strategy. • High renewable energy systems penetration results in net economic and environmental benefits.

Boafo, S T

1984-01-01

The urban bias of the communication infrastructure in most parts of sub-Saharan Africa has comprised a major obstacle to the participation of the rural population in development decsion making. This article describes the Wonsuom rural communication pilot project in Ghana, aimed at providing communication technologies at the grassroots level to enhance the contribution of communication in rural development. When fully operational, the project will use a combination of a rural newspaper published in the local Fante language, rural radio broadcasts, radio listening clubs, and slide projectors to carry development-oriented information to rural communities and mobilize people for development programs. The project, which is carried out by the School of Journalism and Communication of the University of Ghana, covers 22 rural communities with a population of 150,000. The radio programs, started in 1983, include local and national news; discussions involving local community leaders, farmers, fishermen, and extension agents on problems facing the community and on issues such as primary health care and family planning; and features on the achievements of individual community members and development activities. Radio listening clubs meet on a regular basis to listen to the broadcasts, discuss issues highlighted, and deliberate on ways to generate development projects in their community. The discussions are recorded for subsequent broadcast on the program, creating a 2-way communication process. The listening clubs also serve as the focus of social and cultural life in the communities. Publication of the newspaper has been delayed by problems stemming from Ghana's socioeconomic crisis, but newspaper reading clubs are also projected.

Impacts of Rainfall Variability, Land Use and Land Cover Change on Stream Flow of the Black Volta Basin, West Africa

Directory of Open Access Journals (Sweden)

Komlavi Akpoti

2016-07-01

Full Text Available Potential implications of rainfall variability along with Land Use and Land Cover Change (LULC on stream flow have been assessed in the Black Volta basin using the SWAT model. The spatio-temporal variability of rainfall over the Black Volta was assessed using the Mann-Kendall monotonic trend test and the Sen’s slope for the period 1976–2011. The statistics of the trend test showed that 61.4% of the rain gauges presented an increased precipitation trend whereas the rest of the stations showed a decreased trend. However, the test performed at the 95% confidence interval level showed that the detected trends in the rainfall data were not statistically significant. Land use trends between the year 2000 and 2013 show that within thirteen years, land use classes like bare land, urban areas, water bodies, agricultural lands, deciduous forests and evergreen forests have increased respectively by 67.06%, 33.22%, 7.62%, 29.66%, 60.18%, and 38.38%. Only grass land has decreased by 44.54% within this period. Changes in seasonal stream flow due to LULC were assessed by defining dry and wet seasons. The results showed that from year 2000 to year 2013, the dry season discharge has increased by 6% whereas the discharge of wet season has increased by 1%. The changes in stream flows components such us surface run-off (SURF_Q, lateral flow (LAT_Q and ground water contribution to stream flow (GW_Q and also on evapotranspiration (ET changes due to LULC was evaluated. The results showed that between the year 2000 and 2013, SURF_Q and LAT_Q have respectively increased by 27% and 19% while GW_Q has decreased by 6% while ET has increased by 4.59%. The resultant effects are that the water yield to stream flow has increased by 4%.

Sanctuaries for lake trout in the Great Lakes

Science.gov (United States)

Stanley, Jon G.; Eshenroder, Randy L.; Hartman, Wilbur L.

1987-01-01

Populations of lake trout, severely depleted in Lake Superior and virtually extirpated from the other Great Lakes because of sea lamprey predation and intense fishing, are now maintained by annual plantings of hatchery-reared fish in Lakes Michigan, Huron, and Ontario and parts of Lake Superior. The extensive coastal areas of the Great Lakes and proximity to large populations resulted in fishing pressure on planted lake trout heavy enough to push annual mortality associated with sport and commercial fisheries well above the critical level needed to reestablish self-sustaining stocks. The interagency, international program for rehabilitating lake trout includes controlling sea lamprey abundance, stocking hatchery-reared lake trout, managing the catch, and establishing sanctuaries where harvest is prohibited. Three lake trout sanctuaries have been established in Lake Michigan: the Fox Island Sanctuary of 121, 500 ha, in the Chippewa-Ottawa Treaty fishing zone in the northern region of the lake; the Milwaukee Reef Sanctuary of 160, 000 ha in midlake, in boundary waters of Michigan and Wisconsin; and Julian's Reef Sanctuary of 6, 500 ha, in Illinois waters. In northern Lake Huron, Drummond Island Sanctuary of 55, 000 ha is two thirds in Indian treaty-ceded waters in Michigan and one third in Ontario waters of Canada. A second sanctuary, Six Fathom Bank-Yankee Reef Sanctuary, in central Lake Huron contains 168, 000 ha. Sanctuary status for the Canadian areas remains to be approved by the Provincial government. In Lake Superior, sanctuaries protect the spawning grounds of Gull Island Shoal (70, 000 ha) and Devils Island Shoal (44, 000 ha) in Wisconsin's Apostle Island area. These seven sanctuaries, established by the several States and agreed upon by the States, Indian tribes, the U.S. Department of the Interior, and the Province of Ontario, contribute toward solving an interjurisdictional fishery problem.

2018-01-01

Although the public health importance of the association between television (TV) viewing and obesity and/or related outcomes have been demonstrated in both cross-sectional and prospective studies elsewhere, similar studies are lacking within the African region. With the view to fill this gap in the literature, the current study explored the association between TV exposure and overweight/obesity among Ghanaian women. Based on a sample of 4158 women, descriptive statistics and binary logistic regression were applied to data on TV ownership, TV viewing frequency, and body mass index (BMI) measures from the 2014 Ghana Demographic and Health Survey (GDHS) to explore the association between TV exposure and overweight/obesity among Ghanaian women. Despite controlling for other factors (age educational level, marital status, wealth quintile, occupation, type of locality, and parity), the results show that women with TV in their households, and with high TV exposure were significantly ( P  TV in their households, and no TV exposure. The study demonstrates that increased TV exposure is significantly associated with overweight/obesity among women in Ghana even after adjusting for other factors. Interventions aimed at tackling obesity in Ghana should focus on encouraging the uptake of more physically demanding pastime activities in place of TV "sit time".

Healthy firms: constraints to growth among private health sector facilities in Ghana and Kenya.

Directory of Open Access Journals (Sweden)

Nicholas E Burger

Full Text Available BACKGROUND: Health outcomes in developing countries continue to lag the developed world, and many countries are not on target to meet the Millennium Development Goals. The private health sector provides much of the care in many developing countries (e.g., approximately 50 percent in Sub-Saharan Africa, but private providers are often poorly integrated into the health system. Efforts to improve health systems performance will need to include the private sector and increase its contributions to national health goals. However, the literature on constraints private health care providers face is limited. METHODOLOGY/PRINCIPAL FINDINGS: We analyze data from a survey of private health facilities in Kenya and Ghana to evaluate growth constraints facing private providers. A significant portion of facilities (Ghana: 62 percent; Kenya: 40 percent report limited access to finance as the most significant barrier they face; only a small minority of facilities report using formal credit institutions to finance day to day operations (Ghana: 6 percent; Kenya: 11 percent. Other important barriers include corruption, crime, limited demand for goods and services, and poor public infrastructure. Most facilities have paper-based rather than electronic systems for patient records (Ghana: 30 percent; Kenya: 22 percent, accounting (Ghana: 45 percent; Kenya: 27 percent, and inventory control (Ghana: 41 percent; Kenya: 24 percent. A majority of clinics in both countries report undertaking activities to improve provider skills and to monitor the level and quality of care they provide. However, only a minority of pharmacies report undertaking such activities. CONCLUSIONS/SIGNIFICANCE: The results suggest that improved access to finance and improving business processes especially among pharmacies would support improved contributions by private health facilities. These strategies might be complementary if providers are more able to take advantage of increased access to

Prospects for bioenergy use in Ghana using Long-range Energy Alternatives Planning model

International Nuclear Information System (INIS)

Kemausuor, Francis; Nygaard, Ivan; Mackenzie, Gordon

2015-01-01

As Ghana's economy grows, the choice of future energy paths and policies in the coming years will have a significant influence on its energy security. A Renewable Energy Act approved in 2011 seeks to encourage the influx of renewable energy sources in Ghana's energy mix. The new legal framework combined with increasing demand for energy has created an opportunity for dramatic changes in the way energy is generated in Ghana. However, the impending changes and their implication remain uncertain. This paper examines the extent to which future energy scenarios in Ghana could rely on energy from biomass sources, through the production of biogas, liquid biofuels and electricity. Analysis was based on moderate and high use of bioenergy for transportation, electricity generation and residential fuel using the LEAP (Long-range Energy Alternatives Planning) model. Results obtained indicate that introducing bioenergy to the energy mix could reduce GHG (greenhouse gas) emissions by about 6 million tonnes CO_2e by 2030, equivalent to a 14% reduction in a business-as-usual scenario. This paper advocates the use of second generation ethanol for transport, to the extent that it is economically exploitable. Resorting to first generation ethanol would require the allocation of over 580,000 ha of agricultural land for ethanol production. - Highlights: • This paper examines modern bioenergy contribution to Ghana's future energy mix. • Three scenarios are developed and analysed. • Opportunities exist for modern bioenergy to replace carbon intensive fuels. • Introducing modern bioenergy to the mix could result in a 14% reduction in GHG.

2016-01-01

Full Text Available Background. There is a paucity of empirical literature in Ghana on rural areas and their utilisation of health facilities. The study examined the effects of the sociodemographics of rural women on place of delivery in the country. Methods. The paper made use of data from the 2014 Ghana Demographic and Health Survey. Women from rural areas who had given birth within five years prior to the survey were included in the analysis. Descriptive analyses and binary logistic regression were used to analyse the data. Results. Wealth, maternal education, ecological zone, getting money for treatment, ethnicity, partner’s education, parity, and distance to a health facility were found as the determinants of place of delivery among women in rural Ghana. Women in the richest wealth quintile were three times (OR = 3.04, 95% CI = 0.35–26.4 more likely to deliver at a health facility than the poorest women. Conclusions. It behoves the relevant stakeholders including the Ghana Health Service and the Ministry of Health to pay attention to the wealth status, maternal education, ecological zone, ethnicity, partner’s education, parity, and distance in their planning regarding delivery care in rural Ghana.

Evolution of alkaline lakes - Lake Van case study

Tillman Meyer, Felix; Viehberg, Finn; Bahroun, Sonya; Wolf, Annabel; Immenhauser, Adrian; Kwiecien, Ola

2017-04-01

Lake Van in Eastern Anatolia (Turkey) is the largest terminal soda lake on Earth. The lake sedimentary profile covers ca. 600 ka (Stockhecke et al. 2014) Based on lithological changes, the presence of freshwater microfossils and close-to-freshwater pH value in the pore water, members of ICDP PALEOVAN concluded that Lake Van might have started as an open lake. Here we show paleontological and geochemical evidence in favour of this idea and constrain the time, when Lake Van likely transformed into a closed lake. Additionally we provide the first conceptual model of how this closure may have happened. Our archives of choice are inorganic and biogenic carbonates, separated by wet sieving. We identified microfossil assemblages (fraction > 125 µm) and performed high-resolution oxygen isotope (delta18O) and elemental (Mg/Ca, Sr/Ca) analyses of the fraction plants growing in the photic zone as food supply. These two aspects point to an increasing salinity in a shallowing lake. The delta18O values of inorganic carbonates are relatively low during the initial phase of Lake Van and increase abruptly (ca. 7‰) after 530 ka BP. At approximately the same time combination of Sr/Ca and Mg/Ca data suggest first occurrence of aragonite. Again, these findings suggest geochemical changes of the lake water concurrent with transition documented by microfossils. Comparison between Lake Van and Lake Ohrid (Lacey et al. 2016) delta18O data, precludes regional climate change (e.g.: increased evaporation) as the main driver of observed changes. With no evidence for increased volcanic or tectonic activity (e.g.: tephra layers, deformation structures, slumping) in the Lake Van sedimentary profile around 530 ka, it seems unlikely that a pyroclastic flow blocked the outflow of the lake. Alternatively, a portion of inflow has been diverged which might have caused a change in the hydrological balance and lake level falling below its outlet. However, as no geomorphological data confirming this

The article draws on the multi-level perspective (MLP) and global value chain (GVC) frameworks to analyse the drivers and trajectories of foreign private investment in biofuel production in Ghana. It is based on a narrative of the evolution of a niche for jatropha production in Ghana in the period...... a new agriculture-based value chain for global biofuel markets, i.e. high volume requirements, high capital needs, and market risks contributed to the collapse of the jatropha sector in Ghana. A low level of learning and knowledge sharing between jatropha actors in Ghana, alongside weak public R......&D support, reduced access to technical and managerial information. Confirming previous GVC research on biofuels, policy and NGOs had a stronger influence on the jatropha value chain than in typical agricultural chains.

Aquaculture in Ghana has over the years been little productive despite earlier claims about the high potential of the country. These claims are supported by an abundance of latent natural resources that can support large scale commercial production and the existence of a strong traditional market for fish products. A survey of consumer behavior in the local market for tilapia and fish in general was conducted in Ghana. The data were subjected to tabulation and multivariate analysis to assess ...

Volunteer tourists' motivations for choosing homestay in the Kumasi Metropolis of Ghana

Directory of Open Access Journals (Sweden)

Elizabeth Agyeiwaah

2013-01-01

Full Text Available Volunteer tourists’ motivations for choosing homestay accommodation have received little attention from researchers. The objective of this research was to explore the push and pull factors that account for volunteer tourists’ choice of homestay in the Kumasi Metropolis of Ghana. Insights gained from this study will inure better understanding of volunteer tourists’ behaviour to ensure appropriate service delivery by homestay providers. With the help of the "Push and Pull" motivation model by Dann (1977, the findings indicated two main push factors: socio-cultural immersion and economic value; and pull factors: environmental sensitiveness and community service and development. The study found that the most important push and pull factors as perceived by volunteers to Ghana are socio-cultural immersion and environmental sensitiveness. The study confirms the supporting role of homestay for volunteer tourists to Ghana. In the end, the implications of this study are discussed.

Full Text Available Artisanal and small-scale gold mining (ASGM is growing in many regions of the world including Ghana. The problems in these communities are complex and multi-faceted. To help increase understanding of such problems, and to enable consensus-building and effective translation of scientific findings to stakeholders, help inform policies, and ultimately improve decision making, we utilized an Integrated Assessment approach to study artisanal and small-scale gold mining activities in Ghana. Though Integrated Assessments have been used in the fields of environmental science and sustainable development, their use in addressing specific matter in public health, and in particular, environmental and occupational health is quite limited despite their many benefits. The aim of the current paper was to describe specific activities undertaken and how they were organized, and the outputs and outcomes of our activity. In brief, three disciplinary workgroups (Natural Sciences, Human Health, Social Sciences and Economics were formed, with 26 researchers from a range of Ghanaian institutions plus international experts. The workgroups conducted activities in order to address the following question: What are the causes, consequences and correctives of small-scale gold mining in Ghana? More specifically: What alternatives are available in resource-limited settings in Ghana that allow for gold-mining to occur in a manner that maintains ecological health and human health without hindering near- and long-term economic prosperity? Several response options were identified and evaluated, and are currently being disseminated to various stakeholders within Ghana and internationally.

Lake whitefish diet, condition, and energy density in Lake Champlain and the lower four Great Lakes following dreissenid invasions

Science.gov (United States)

Herbst, Seth J.; Marsden, J. Ellen; Lantry, Brian F.

2013-01-01

Lake Whitefish Coregonus clupeaformis support some of the most valuable commercial freshwater fisheries in North America. Recent growth and condition decreases in Lake Whitefish populations in the Great Lakes have been attributed to the invasion of the dreissenid mussels, zebra mussels Dreissena polymorpha and quagga mussels D. bugensis, and the subsequent collapse of the amphipod, Diporeia, a once-abundant high energy prey source. Since 1993, Lake Champlain has also experienced the invasion and proliferation of zebra mussels, but in contrast to the Great Lakes, Diporeia were not historically abundant. We compared the diet, condition, and energy density of Lake Whitefish from Lake Champlain after the dreissenid mussel invasion to values for those of Lake Whitefish from Lakes Michigan, Huron, Erie, and Ontario. Lake Whitefish were collected using gill nets and bottom trawls, and their diets were quantified seasonally. Condition was estimated using Fulton's condition factor (K) and by determining energy density. In contrast to Lake Whitefish from some of the Great Lakes, those from Lake Champlain Lake Whitefish did not show a dietary shift towards dreissenid mussels, but instead fed primarily on fish eggs in spring, Mysis diluviana in summer, and gastropods and sphaeriids in fall and winter. Along with these dietary differences, the condition and energy density of Lake Whitefish from Lake Champlain were high compared with those of Lake Whitefish from Lakes Michigan, Huron, and Ontario after the dreissenid invasion, and were similar to Lake Whitefish from Lake Erie; fish from Lakes Michigan, Huron, and Ontario consumed dreissenids, whereas fish from Lake Erie did not. Our comparisons of Lake Whitefish populations in Lake Champlain to those in the Great Lakes indicate that diet and condition of Lake Champlain Lake Whitefish were not negatively affected by the dreissenid mussel invasion.

Science, technology and innovation have long played a role in Ghana's vision for development, including in improving its health outcomes. However, so far little research has been conducted on Ghana's capacity for health innovation to address local diseases. This research aims to fill that gap, mapping out the key actors involved, highlighting examples of indigenous innovation, setting out the challenges ahead and outlining recommendations for strengthening Ghana's health innovation system. Case study research methodology was used. Data were collected through reviews of academic literature and policy documents and through open-ended, face-to-face interviews with 48 people from across the science-based health innovation system. Data was collected over three visits to Ghana from February 2007 to August 2008, and stakeholders engaged subsequently. Ghana has strengths which could underpin science-based health innovation in the future, including health and biosciences research institutions with strong foreign linkages and donor support; a relatively strong regulatory system which is building capacity in other West African countries; the beginnings of new funding forms such as venture capital; and the return of professionals from the diaspora, bringing expertise and contacts. Some health products and services are already being developed in Ghana by individual entrepreneurs, which are innovative in the sense of being new to the country and, in some cases, the continent. They include essential medicines, raw pharmaceutical materials, new formulations for pediatric use and plant medicines at various stages of development. While Ghana has many institutions concerned with health research and its commercialization, their ability to work together to address clear health goals is low. If Ghana is to capitalize on its assets, including political and macroeconomic stability which underpin investment in health enterprises, it needs to improve the health innovation environment

Providers of antenatal care services in Ghana: evidence from Ghana demographic and health surveys 1988-2014.

Antenatal care is one of the three most essential care - antenatal, delivery and post-natal, given to women during pregnancy and has the potential to contribute towards the achievement of the Sustainable Development Goal (SDG) target 3.1- reducing the global maternal mortality ratio to less than 70 per 100,000 and target 3.8 - achieve universal health coverage. The main objective is to examine the contribution of the various providers of antenatal care services in Ghana from 1988 to 2014. The study uses data from all the six rounds of the Ghana Demographic and Health Survey (GDHS). Binary logistic regression models were applied to examine the association between background characteristics of respondents and providers of antenatal care services. The results show that majority of antenatal care services were provided by nurses over the period under review. The proportion of women who received antenatal care services from nurses improved over the period from 55% in 1988 to 89.5% in 2014. Moreover, there was a decline in antenatal care services provided by traditional birth attendants and women who did not receive antenatal care services from any service provider over the years under review. It was observed that women from rural areas were more likely to utilise antenatal care services provided by traditional birth attendants, whilst those from urban areas were more likely to utilise antenatal care from doctors and nurses. To further improve access to and utilisation of antenatal care services provided by nurses and doctors it is recommended that the Ghana Health Service and the Ministry of Health should put in place systems aimed at improving on the quality of care given such as regular training workshops for health personnel and assessment of patient's satisfaction with services provided. Also, they should encourage women in rural areas especially those from the savannah zone to utilise antenatal care services from skilled providers through social and behaviour

Intercomparison of Evapotranspiration Over the Savannah Volta Basin in West Africa Using Remote Sensing Data

Directory of Open Access Journals (Sweden)

T. P. Burt

2008-04-01

Full Text Available This paper compares evapotranspiration estimates from two complementary satellite sensors – NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS and ESA’s ENVISAT Advanced Along-Track Scanning Radiometer (AATSR over the savannah area of the Volta basin in West Africa. This was achieved through solving for evapotranspiration on the basis of the regional energy balance equation, which was computationally-driven by the Surface Energy Balance Algorithm for Land algorithm (SEBAL. The results showed that both sensors are potentially good sources of evapotranspiration estimates over large heterogeneous landscapes. The MODIS sensor measured daily evapotranspiration reasonably well with a strong spatial correlation (R2=0.71 with Landsat ETM+ but underperformed with deviations up to ~2.0 mm day-1, when compared with local eddy correlation observations and the Penman-Monteith method mainly because of scale mismatch. The AATSR sensor produced much poorer correlations (R2=0.13 with Landsat ETM+ and conventional ET methods also because of differences in atmospheric correction and sensor calibration over land.

Electron cryotomography of vitrified cells with a Volta phase plate.

Electron cryotomography provides a means of studying the three dimensional structure of pleomorphic objects, such as organelles or cells, with a resolution of 1-3nm. A limitation in the study of radiation sensitive biological samples is the low signal-to-noise ratio of the tomograms which may obscure fine details. To overcome this limitation, the recently developed Volta phase plate (VPP) was applied in electron cryotomographic studies of a wide range of cellular structures, from magnetotactic bacteria to primary cultured neurons. The results show that the VPP improves contrast significantly and consequently the signal-to-noise ratio of the tomograms, moreover it avoids disturbing fringing artifacts typical for Zernike phase plates. The contrast improvement provided by the VPP was also confirmed in projection images of relatively thick (∼400nm) samples. In order to investigate the respective contributions of the VPP and the energy filter, images acquired with different combinations of the two were compared. Zero-loss energy filtering reduced the background noise in thicker areas of the sample and improved the contrast of features such as poly-β-hydroxybutyrate granules in magnetotactic bacteria, whereas the VPP provided an overall contrast improvement for all sample areas. After 3D reconstruction, tomograms acquired with the combination of a VPP and an energy filter showed structural features in neuronal processes with outstanding clarity. We also show that the VPP can be combined with focused ion beam milling to examine structures embedded deeply inside cells. Thus, we expect that VPP will become a standard element of the electron cryotomography workflow. Copyright © 2015 Elsevier Inc. All rights reserved.

Although there are current efforts to integrate herbal medicine (HM) into mainstream healthcare in Ghana, there is paucity of empirical evidence on the acceptability and concurrent use of HM, in the formal health facilities in Ghana. This study sought to determine client perception, disclosure and acceptability of integrating herbal medicine in mainstream healthcare in Kumasi, Ghana. A cross-sectional study was conducted from May to August, 2015. Five hundred patients presenting at the outpatient departments of Kumasi South, Suntreso and Tafo Government Hospitals in Kumasi were randomly selected. Interviews were conducted with the use of structured questionnaires. A logistic regression analysis, using backward selection, was conducted to determine the influence of socio-demographic and facility related factors on the odds of using HM at the facility. All statistical tests were two-sided and considered significant at a p-value of herbal medicines. Respondents who rated themselves wealthy had increased odds of using herbal medicines at the health facility as compared to those who rated themselves poor (OR = 4.9; 95%CI = 1.6-15.3). This study shows that integration of herbal medicine is feasible and herbal medicines may be generally accepted as a formal source of healthcare in Ghana. The results of this study might serve as a basis for improvement and upscale of the herbal medicine integration programme in Ghana.

Climate change has been shown to increase the number of mountain lakes across various mountain ranges in the World. In Central Asia, and in particular on the territory of Uzbekistan, a detailed assessment of glacier lakes and their evolution over time is, however lacking. For this reason we created the first detailed inventory of mountain lakes of Uzbekistan based on recent (2002-2014) satellite observations using WorldView-2, SPOT5, and IKONOS imagery with a spatial resolution from 2 to 10m. This record was complemented with data from field studies of the last 50years. The previous data were mostly in the form of inventories of lakes, available in Soviet archives, and primarily included localized in-situ data. The inventory of mountain lakes presented here, by contrast, includes an overview of all lakes of the territory of Uzbekistan. Lakes were considered if they were located at altitudes above 1500m and if lakes had an area exceeding 100m 2 . As in other mountain regions of the World, the ongoing increase of air temperatures has led to an increase in lake number and area. Moreover, the frequency and overall number of lake outburst events have been on the rise as well. Therefore, we also present the first outburst assessment with an updated version of well-known approaches considering local climate features and event histories. As a result, out of the 242 lakes identified on the territory of Uzbekistan, 15% are considered prone to outburst, 10% of these lakes have been assigned low outburst potential and the remainder of the lakes have an average level of outburst potential. We conclude that the distribution of lakes by elevation shows a significant influence on lake area and hazard potential. No significant differences, by contrast, exist between the distribution of lake area, outburst potential, and lake location with respect to glaciers by regions. Copyright © 2017 Elsevier B.V.

"Correcting an Erring Wife Is Normal": Moral Discourses of Spousal Violence in Ghana.

Science.gov (United States)

Adjei, Stephen Baffour

2018-06-01

This study draws insights from discursive psychology to explore moral discourses of spousal violence in Ghana. In particular, it investigates how sociocultural norms and practices are invoked in talk of perpetrators and victims as moral warrants for husband-to-wife abuse in Ghana. Semi-structured focus group and personal interviews were conducted with a total of 40 participants: 16 victims, 16 perpetrators, and eight key informants from rural and urban Ghana. Participants' discursive accounts suggest that husbands have implicit moral right and obligation to punish their wives for disobedience and other infractions against male authority in marriage. Both perpetrators and victims build their talk around familiar normative discourses and practices that provide tacit support for spousal violence in Ghana. While perpetrators mobilize culturally resonant and normative repertoires to justify abuse, blame their victims, and manage their moral accountability; victims position husband-to-wife abuse as normal, legitimate, disciplinary, and corrective. These moral discourses of spousal violence apparently serve to relieve perpetrators of moral agency; prime battered women to accept abuse; and devastate their agency to leave abusive marital relationships. The findings contribute to our understanding of how cultural and social norms of spousal violence are morally constituted, reproduced, and sustained in talk of perpetrators, victims, and other key members of society.

International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Ghana

International Nuclear Information System (INIS)

1985-01-01

A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) Mission to Ghana. The IUREP Orientation Phase Mission to Ghana estimates that the Speculative Resources of that country fall within the range of 15 000 to 40 000 tonnes of uranium. The majority of this potential is expected to be located in the Proterozoic Panafrican Mobile Belt (up to 17 000 tonnes uranium) and the Paleozoic Obosum Beds of the Voltaian basin (up to 15 000 tonnes uranium), the remainder being associated with various other geological environments. The mission recommends that over a period of three (3) years approximately U.S. $5 million) would be spent on exploration in Ghana. A major part of this (U.S $2 million) would be spent on an airborne spectrometer survey over the Voltaian basin (Obosum beds), much of the remainder being spent on ground surveys, trenching and percussion drilling.

Full Text Available Researchers over the years have shown that the FDI has had a positive influence on national economic growth and development. This research examines the FDI Inflow in Ghana and the contribution of the Selected Countries observed FDI inflows between 2000 and 2014. While comparing the quantitative data, the study showed that the selected countries contributed more to the Agriculture, Manufacturing, Building/Construction, and Service sectors of Ghana in terms of volumes of investments and projects as compared to other sectors of the economy due to incentives attached to prioritized economic sectors. On employment generation, the selected countries percentage share of domestic employment was higher than that of expatriate employment due to Ghana investment laws that allows investor with a specific minimum capital of three hundred thousand dollars to employ minimum of ten Ghanaians for every foreign employee hired.

Thomas K. Karikari

2015-06-01

Full Text Available The application of genomic tools and technologies has shown the potential to help improve healthcare and our understanding of disease mechanisms. While genomic tools are increasingly being applied to research on infectious diseases, malaria and neglected tropical diseases in Africa, an area that has seen little application of genomic approaches on this continent is neuroscience. In this article, we examined the prospects of developing neurogenomics research and its clinical use in Ghana, one of the African countries actively involved in genomics research. We noted that established international research funding sources and foundations in genomic research such as H3ABioNet nodes established at a couple of research centres in Ghana provide excellent platforms for extending the usage of genomic tools and techniques to neuroscience-related research areas. However, existing challenges such as the (i lack of degree programmes in neuroscience, genomics and bioinformatics; (ii low availability of infrastructure and appropriately-trained scientists; and (iii lack of local research funding opportunities, need to be addressed. To promote and safeguard the long-term sustainability of neurogenomics research in the country, the impact of the existing challenges and possible ways of addressing them have been discussed.

Infections acquired from improperly sterilized equipment are recognized as a major impediment to safe health care delivery, with consequences that are often deadly for patients. Radiation technology plays a major role in many countries in making medical equipment safer. “The use of nuclear applications, such as exposing medical items to gamma radiation, helps Ghana protect its people from avoidable sicknesses that can occur if items like syringes are not properly sterilized,” said Abraham Adu-Gyamfi, Manager of the Radiation Technology Centre of the Ghana Atomic Energy Commission’s Biotechnology and Nuclear Agriculture Research Institute in Accra.

Lake-level frequency analysis for Devils Lake, North Dakota

Science.gov (United States)

Wiche, Gregg J.; Vecchia, Aldo V.

1996-01-01

Two approaches were used to estimate future lake-level probabilities for Devils Lake. The first approach is based on an annual lake-volume model, and the second approach is based on a statistical water mass-balance model that generates seasonal lake volumes on the basis of seasonal precipitation, evaporation, and inflow. Autoregressive moving average models were used to model the annual mean lake volume and the difference between the annual maximum lake volume and the annual mean lake volume. Residuals from both models were determined to be uncorrelated with zero mean and constant variance. However, a nonlinear relation between the residuals of the two models was included in the final annual lakevolume model.Because of high autocorrelation in the annual lake levels of Devils Lake, the annual lake-volume model was verified using annual lake-level changes. The annual lake-volume model closely reproduced the statistics of the recorded lake-level changes for 1901-93 except for the skewness coefficient. However, the model output is less skewed than the data indicate because of some unrealistically large lake-level declines. The statistical water mass-balance model requires as inputs seasonal precipitation, evaporation, and inflow data for Devils Lake. Analysis of annual precipitation, evaporation, and inflow data for 1950-93 revealed no significant trends or long-range dependence so the input time series were assumed to be stationary and short-range dependent.Normality transformations were used to approximately maintain the marginal probability distributions; and a multivariate, periodic autoregressive model was used to reproduce the correlation structure. Each of the coefficients in the model is significantly different from zero at the 5-percent significance level. Coefficients relating spring inflow from one year to spring and fall inflows from the previous year had the largest effect on the lake-level frequency analysis.Inclusion of parameter uncertainty in the model

Lake trout in northern Lake Huron spawn on submerged drumlins

Recent observations of spawning lake trout Salvelinus namaycush near Drummond Island in northern Lake Huron indicate that lake trout use drumlins, landforms created in subglacial environments by the action of ice sheets, as a primary spawning habitat. From these observations, we generated a hypothesis that may in part explain locations chosen by lake trout for spawning. Most salmonines spawn in streams where they rely on streamflows to sort and clean sediments to create good spawning habitat. Flows sufficient to sort larger sediment sizes are generally lacking in lakes, but some glacial bedforms contain large pockets of sorted sediments that can provide the interstitial spaces necessary for lake trout egg incubation, particularly if these bedforms are situated such that lake currents can penetrate these sediments. We hypothesize that sediment inclusions from glacial scavenging and sediment sorting that occurred during the creation of bedforms such as drumlins, end moraines, and eskers create suitable conditions for lake trout egg incubation, particularly where these bedforms interact with lake currents to remove fine sediments. Further, these bedforms may provide high-quality lake trout spawning habitat at many locations in the Great Lakes and may be especially important along the southern edge of the range of the species. A better understanding of the role of glacially-derived bedforms in the creation of lake trout spawning habitat may help develop powerful predictors of lake trout spawning locations, provide insight into the evolution of unique spawning behaviors by lake trout, and aid in lake trout restoration in the Great Lakes.

Full Text Available The article sketches the origins and development of IVF in Ghana as a highly transnational undertaking. Movements are from and to Africa, involving human beings (providers and users, and also refer to other entities such as technologies, skills and knowledge. None of these movements are paid for using public money, neither are they subsidized by international health organizations. Currently, ‘more affordable’ IVF is being introduced into Ghana, on initiative of the first Association of Childless Couples of Ghana (ACCOG, in collaboration with the Belgium based non-profit organization the Walking Egg (tWE, representing another form of transnational networking. The article underlines the scarcity of well-trained embryologists in Ghana, which turns the embryologists’ expertise and skills into a scarce and precious commodity and guarantees this expertise becomes a major challenge for the directors of the private clinics. Next to local Ghanaian couples, the clinics also attend to transnational reproductive travellers, including women and men from neighbouring countries and Ghanaians in the diaspora returning to their country of origin. Their manifold motivations to cross borders and visit the IVF clinics in Ghana provide insight into the structural conditions impeding or facilitating the use of assisted reproductive technologies at different local sites. Transnational movements also include the flow of new procreation practices (such as surrogacy and the use of donor material, which (re-shape existing cultural and societal notions regarding kinship and the importance of blood/genetic ties. Finally, the article lists a number of thematic and theoretical issues which require further exploration and studies.

Rainy Lake contains a native population of lake sturgeon Acipenser fulvescens that has been largely unstudied. The aims of this study were to document the population characteristics of lake sturgeon in Rainy Lake and to relate environmental factors to year-class strength for this population. Gill-netting efforts throughout the study resulted in the capture of 322 lake sturgeon, including 50 recaptures. Lake sturgeon in Rainy Lake was relatively plump and fast growing compared with a 32-population summary. Population samples were dominated by lake sturgeon between 110 and 150 cm total length. Age–structure analysis of the samples indicated few younger (<10 years) lake sturgeon, but the smallest gill net mesh size used for sampling was 102 mm (bar measure) and would not retain small sturgeon. Few lake sturgeon older than age 50 years were captured, and maximum age of sampled fish was 59 years. Few correlations existed between lake sturgeon year-class indices and both annual and monthly climate variables, except that mean June air temperature was positively correlated with year-class strength. Analysis of Rainy Lake water elevation and resulting lake sturgeon year-class strength indices across years yielded consistent but weak negative correlations between late April and early June, when spawning of lake sturgeon occurs. The baseline data collected in this study should allow Rainy Lake biologists to establish more specific research questions in the future.

Ghana's maternal mortality ratio remains high despite efforts made to meet Millennium Development Goal 5. A number of studies have been conducted on maternal mortality in Ghana; however, little is known about how the causes of maternal mortality are distributed in different socio-demographic subgroups. Therefore the aim of this study was to assess and analyse the causes of maternal mortality according to socio-demographic factors in Ghana. The causes of maternal deaths were assessed with respect to age, educational level, rural/urban residence status and marital status. Data from a five year retrospective survey was used. The data was obtained from Ghana Maternal Health Survey 2007 acquired from the database of Ghana Statistical Service. A total of 605 maternal deaths within the age group 12-49 years were analysed using frequency tables, cross-tabulations and logistic regression. Haemorrhage was the highest cause of maternal mortality (22.8%). Married women had a significantly higher risk of dying from haemorrhage, compared with single women (adjusted OR = 2.7, 95%CI = 1.2-5.7). On the contrary, married women showed a significantly reduced risk of dying from abortion compared to single women (adjusted OR = 0.2, 95%CI = 0.1-0.4). Women aged 35-39 years had a significantly higher risk of dying from haemorrhage (aOR 2.6, 95%CI = 1.4-4.9), whereas they were at a lower risk of dying from abortion (aOR 0.3, 95% CI = 0.1-0.7) compared to their younger counterparts. The risk of maternal death from infectious diseases decreased with increasing maternal age, whereas the risk of dying from miscellaneous causes increased with increasing age. The study shows evidence of variations in the causes of maternal mortality among different socio-demographic subgroups in Ghana that should not be overlooked. It is therefore recommended that interventions aimed at combating the high maternal mortality in Ghana should be both cause-specific as well as target-specific.

Euthanasia, assisted dying and the right to die in Ghana: a socio-legal analysis.

Science.gov (United States)

Owusu-Dapaa, Ernest

2013-12-01

There is unanimity among states to protect the continuation of life of the individual as a safeguard against their collective extinction. The right to life is accordingly guaranteed but its antithesis, the right to die is the subject of an unending debate. The controversy over the right to die is deepened by rapid advances in medicine, creating the capability for prolongation of life beyond the span which one's natural strength can endure. Ghana's supreme law explicitly guarantees the right to life but remains ambiguous on right to die, particularly euthanasia and assisted dying. Thus, some of the other rights, such as the right to dignity and not to be tortured, can creatively be exploited to justify some instances of euthanasia. Ghana's criminal code largely proscribes euthanasia. Notwithstanding, proscription of euthanasia and assisted dying by the law, in Ghana's empirical work undertaken in some of the communities in Ghana, suggests that euthanasia is quietly practisedin health facilities and private homes, especially in the rural areas. Contrary to the popular reasons assigned in the literature of the Western world, with respect to the practice or quest for legalization of euthanasia as being a necessity for providing relief from pain or hopeless quality of life, empirical data from social and anthropological studies conducted in Ghana reveal that poverty is the motivation for informal euthanasia practice in Ghana rather than genuine desire on part of patients to die or their relatives to see to their accelerated death. Apart from poverty, traditional cultural values of African societies consider non-natural death as a taboo and ignominy to the victim and his family. Thus, any move by the government to legalize euthanasia will need to be informed by widely held consultations and a possible referendum; otherwise the law may be just a mere transplant of Western models of legislation on euthanasia without reflecting the ethos of the African people.

Zooplankton communities in a large prealpine lake, Lake Constance: comparison between the Upper and the Lower Lake

2005-08-01

Full Text Available The zooplankton communities of two basins of a large lake, Lake Constance, were compared during the years 2002 and 2003. The two basins differ in morphology, physical and chemical conditions. The Upper Lake basin has a surface area of 470 km2, a mean depth of 100 and a maximum depth of 250 m; the Lower Lake basin has a surface area of 62 km2, a mean depth of only 13 and a maximum depth of 40 m. Nutrient, chlorophyll-a concentrations and mean temperatures are somewhat higher in the Lower than in the Upper Lake. Total abundance of rotifers (number per m2 lake surface was higher and rotifer development started earlier in the year in the Lower than in the Upper Lake. Total abundance of crustaceans was higher in the Upper Lake in the year 2002; in the year 2003 no difference in abundance could be detected between the lake basins, although in summer crustacean abundance was higher in the Lower than in the Upper Lake. Crustacean communities differed significantly between lake basins while there was no apparent difference in rotifer communities. In the Lower Lake small crustaceans, like Bosmina spp., Ceriodaphnia pulchella and Thermocyclops oithonoides prevailed. Abundance (number per m2 lake surface of predatory cladocerans, large daphnids and large copepods was much lower in the Lower than in the Upper Lake, in particular during the summer months. Ordination with nonmetric multidimensional scaling (NMS separated communities of both lakes along gradients that correlated with temperature and chlorophyll a concentration. Clutches of copepods were larger in the Lower than in the Upper Lake. No difference could be detected in clutch size of large daphnids between lake basins. Our results show that zooplankton communities in different basins of Lake Constance can be very different. They further suggest that the lack of large crustaceans in particular the lack of large predatory cladocerans in the Lower Lake can have negative effects on growth and

Lake trout rehabilitation in Lake Erie: a case history

Science.gov (United States)

Cornelius, Floyd C.; Muth, Kenneth M.; Kenyon, Roger

1995-01-01

Native lake trout (Salvelinus namaycush) once thrived in the deep waters of eastern Lake Erie. The impact of nearly 70 years of unregulated exploitation and over 100 years of progressively severe cultural eutrophication resulted in the elimination of lake trout stocks by 1950. Early attempts to restore lake trout by stocking were unsuccessful in establishing a self-sustaining population. In the early 1980s, New York's Department of Environmental Conservation, Pennsylvania's Fish and Boat Commission, and the U.S. Fish and Wildlife Service entered into a cooperative program to rehabilitate lake trout in the eastern basin of Lake Erie. After 11 years of stocking selected strains of lake trout in U.S. waters, followed by effective sea lamprey control, lake trout appear to be successfully recolonizing their native habitat. Adult stocks have built up significantly and are expanding their range in the lake. Preliminary investigations suggest that lake trout reproductive habitat is still adequate for natural reproduction, but natural recruitment has not been documented. Future assessments will be directed toward evaluation of spawning success and tracking age-class cohorts as they move through the fishery.

Microbiology of Lonar Lake and other soda lakes

Soda lakes are saline and alkaline ecosystems that are believed to have existed throughout the geological record of Earth. They are widely distributed across the globe, but are highly abundant in terrestrial biomes such as deserts and steppes and in geologically interesting regions such as the East African Rift valley. The unusual geochemistry of these lakes supports the growth of an impressive array of microorganisms that are of ecological and economic importance. Haloalkaliphilic Bacteria and Archaea belonging to all major trophic groups have been described from many soda lakes, including lakes with exceptionally high levels of heavy metals. Lonar Lake is a soda lake that is centered at an unusual meteorite impact structure in the Deccan basalts in India and its key physicochemical and microbiological characteristics are highlighted in this article. The occurrence of diverse functional groups of microbes, such as methanogens, methanotrophs, phototrophs, denitrifiers, sulfur oxidizers, sulfate reducers and syntrophs in soda lakes, suggests that these habitats harbor complex microbial food webs that (a) interconnect various biological cycles via redox coupling and (b) impact on the production and consumption of greenhouse gases. Soda lake microorganisms harbor several biotechnologically relevant enzymes and biomolecules (for example, cellulases, amylases, ectoine) and there is the need to augment bioprospecting efforts in soda lake environments with new integrated approaches. Importantly, some saline and alkaline lake ecosystems around the world need to be protected from anthropogenic pressures that threaten their long-term existence. PMID:23178675

The prevalence of type 2 diabetes mellitus in developing countries like Ghana continues to rise. This study seeks to assess the risk factors of type 2 diabetes mellitus in a Ghanaian setting. An unmatched case-control study among patients receiving care at the out-patient departments of the two major hospitals in the Ho Municipality. Patients diagnosed with type 2 diabetes mellitus were recruited. Appropriate controls with similar ages who were also patients receiving care at the out-patient department of these hospitals were recruited. Both cases and controls were administered a questionnaire that comprises of standardized and validated tools. These tools include WHO STEPs instrument, general practice physical activity questionnaire and rapid eating and activity assessment for patients. Additionally, the research participants were made to undergo physical examinations for weight, height, waist circumference and laboratory testing of fasting venous blood to assess the biochemical factors of interest namely fasting blood glucose and fasting lipids. Analysis of data was done using STATA version 11. A total of 136 (48 cases and 88 controls) participants of which 95 [39 (81.25%) cases and 56 (63.64%) controls] respondents underwent laboratory testing for fasting blood glucose and fasting blood lipid (total cholesterol, HDL cholesterol and triglycerides). Participants were aged between 35 and 62 years. This study reveals a number of risk factors for type 2 diabetes mellitus.

Among countries in West Africa, Ghana is the main focus of the Global Issues Initiative (GII) on Population and AIDS and one of twelve priority countries selected for official development assistance (ODA) under the program. A ten-member project formulation mission sent to Ghana by the Ministry of Foreign Affairs (MOFA) of Japan was in the country during January 10-18. This mission was the first of its kind to be sent to Africa. It was led by the director of the Third Project Formulation Study Division, Project Formulation Study Department, Japan International Cooperation Agency (JICA), and included representatives of MOFA, JICA, and the Ministry of Health and Welfare, and an observer from UNAIDS. The mission's chief objective was to explore possibilities for Japanese cooperation in the areas of population, child health, and HIV/AIDS in line with the Mid-Term Health Strategy (MTHS) formulated in 1995 by the government of Ghana. The mission also explored the possibility of collaboration with major donors, international organizations, international agencies, and NGOs. The mission met with representatives of NGOs from population, women, AIDS, and health-related areas on January 13, who were then briefed upon Japan's Grant Assistance for Grassroots Project for local NGOs. Views were exchanged upon NGO activities.

Full Text Available This study investigates the causes of delay of building construction projects in Ghana to determine the most important according to the key project participants; clients, consultants, and contractors. Thirty-two possible causes of delay were identified from the literature and semi-structured interviews of 15 key players in the implementation process. These delay factors were further categorised into nine major groups. The list of delay causes was subjected to a questionnaire survey for the identification of the most important causes of delay. The field survey included 130 respondents made up of 39 contractors, 37 clients and 54 consultants. The relative importance of the individual causes and the groups were calculated and ranked by their relative importance index. The overall results of the study indicate that the respondents generally agree that financial group factors ranked highest among the major factors causing delay in construction projects in Ghana. The financial group factors were delay in honouring payment certificates, difficulty in accessing credit and fluctuation in prices. Materials group factors are second followed by scheduling and controlling factors.

Inadequate housing in Ghana

Directory of Open Access Journals (Sweden)

Franklin Obeng-Odoom

2011-01-01

Full Text Available Two themes are evident in housing research in Ghana. One involves the study of how to increase the number of dwellings to correct the overall housing deficit, and the other focuses on how to improve housing for slum dwellers. Between these two extremes, there is relatively little research on why the existing buildings are poorly maintained. This paper is based on a review of existing studies on inadequate housing. It synthesises the evidence on the possible reasons for this neglect, makes a case for better maintenance and analyses possible ways of reversing the problem of inadequate housing.

X-ray Fluorescence in Member States: Ghana. The Use of XRF for Contaminated Site Assessment in Ghana. 2. Estimation of Heavy Metals Contamination at Agbogbloshie E-scrap Yard Using EDXRF Technique

2012-01-01

The emergence of the digital age has underscored the important role that electrical and electronic equipment (EEE) plays in a nation's socioeconomic development, including education, health delivery and communications, as well as global connectivity. In 2003 Ghana formulated its policy on information and communications technology (ICT) for accelerated development, with the understanding for instance, that Ghana's accelerated development would not be possible without an ICT-driven development agenda. The demand for EEE in Ghana grows by the day with a corresponding high rate of waste electrical and electronic (WEEE) generation. The WEEE industry in Ghana is a very vibrant one, growing at an amazing rate year after year. Ghana currently imports about 215 000 tonnes of electrical and electronic equipment per annum out of which an estimated 70% are second hand products. About 60-70% of the second hand products arrive in good working condition, 20-30% can be repaired or refurbished to get them functioning and 10-20% are junk and sent directly for the informal recycling. The Agbogbloshie scrap market in Accra came into the limelight following the publication of the report entitled 'Poisoning the Poor' by Greenpeace International. The report gave a damning revelation about the activities of scrap dealers and recyclers at the market. It was noted from the report that surface dust samples contained high concentrations of both heavy metals and persistent organic pollutants due to the unsafe and crude means of retrieving metals and components from the WEEE. This project was therefore designed to determine the heavy metal concentration of surface dust using the EDXRF and estimate the degree of contamination of the dust samples. Surface dust samples were collected from various vicinities within the scrap yard using the methods described above.

Effects of occupational stress and coping mechanisms adopted by radiographers in Ghana

International Nuclear Information System (INIS)

Ashong, G.G.N.A.; Rogers, H.; Botwe, B.O.; Anim-Sampong, S.

2016-01-01

Background: Studies have shown that population of radiography staff within various hospitals in Ghana decreased by 30% in the last decade due to several reasons. One of such reasons understood to be related to stress and job satisfaction which affect work output. Purpose: To investigate the effects of occupational stress and the coping mechanisms adopted by radiographers in Ghana. Method: A descriptive survey using a five-point Likert-scale questionnaire with pre-coded responses was administered via email to respondents. Purposive sampling method was used to select 190 radiographers who work in hospitals in Ghana. Descriptive statistics was mainly used to analyse the data using SPSS Version 20. Results: Of a total 190 questionnaires sent, 122 were completed and returned giving a 64.3% response rate. Majority 78 (64%) of respondents were males and the predominant area of work was conventional radiography. Most radiographers revealed they were stressed with 63% indicating high/very high levels of stress. The consequent effects of stress on radiographers were sick absence, depression and job dissatisfaction. Most of the radiographers used primary interventions to cope with stress. Conclusion: This study has demonstrated that most radiographers in Ghana are stressed. However, they cope well with problem-solving mechanisms. This suggests that the decrease in number of radiographers within various facilities in Ghana by 30% may not necessarily be caused by stress but other factors which need to be investigated. Nevertheless, occupational stress has an effect on radiographers' quality of working life and may directly impact on their behaviour during service delivery. - Highlights: • There is high level of occupational stress among Ghanaian Radiographers. • Some sources and causes of occupational stress among Ghanaian Radiographers were workload, poor pay and shortage of staff. • Job dissatisfaction, depression and sick absence were effects of occupational

The Context and Provenance of Democratization in Ghana (1990-1992

Directory of Open Access Journals (Sweden)

Thomas Maxwell Aidoo

2009-12-01

Full Text Available En la última década y la segunda mitad del siglo XX, ha surgido la opinión consensuada de que las dificultades que han retrasado el desarrollo de África son más políticas que económicas. Los politólogos y expertos en el desarrollo de África, sugirieron que la democratización y la gobernanza eran medios de sacar a África del subdesarrollo. De acuerdo con ello, desde 1990 una ola de democratizaciones se ha extendido por la mayor parte de África. Este artículo examina el contexto y los orígenes del proceso de democratización en Ghana. La política de Ghana experimentó un rápido proceso de transformación entre 1990 y 1992. Este período fue testigo de la desaparición de una década de dictadura militar. Se produjo la reinstauración de un sistema de gobierno pluralista y constitucional. Al mismo tiempo, un dramático crecimiento de la sociedad civil empezó a hacerse visible. El trabajo identifica dos desarrollos: luchas de élites y de masas por la incorporación política y económica respectivamente, y presiones externas, que tuvieron un rol dominante en este proceso. Esto ilumina las fuerzas políticas y actores que conformaron la restauración del orden constitucional/democrático en Ghana. El artículo muestra el surgimiento del movimiento por la democracia en Ghana durante los años noventa a causa de la demanda de inclusión política y económica por parte de elementos marginados. La marginación política y económica ocurrió en circunstancias de monolitismo político, autoritarismo coercitivo y recesión económica, o en palabras de Claude Ake (2000 “persistente subdesarrollo”. La demanda por la inclusión ocurrió en dos niveles –en el nivel de las élites como demanda de una asimilación política y en el nivel de las masas como demanda de una asimilación económica. Entonces, el monolitismo político y el persistente subdesarrollo dieron nacimiento a un movimiento por la democracia cuyo objetivo fue la
