Policy entrepreneurs are individuals who attempt to influence the policy process and its outcomes through their opportunistic or incremental actions. Their success in the policy-making process has been associated with the convergence of four factors: behavioural traits; institutional factors; network position and political capital. Policy entrepreneurs have received little study in low- and middle-income country policy research despite observations of individualized decision-making, informal institutions and the unequal distribution and exercise of power in policymaking. This article aims to identify whether policy entrepreneurs were present in the policy process around integrated community case management (iCCM) in Burkina Faso, whether they were successful in achieving policy change, and whether success or failure can be explained using existing policy entrepreneur frameworks from high-income polities. This mixed methods policy study collected data from in-depth qualitative interviews and social network surveys of actors involved in iCCM policymaking [known locally as C-integrated management of childhood illness (IMCI)]; data were analysed based on the framework categories. Interview data pointed to one key individual who played a significant role in the inclusion of pneumonia treatment into the country's iCCM policy, an issue that had been a point of contention between government policy elites and development partners. Social network data confirmed that this actor was strategically located in the policy network to be able to reach the most other actors and to be able to control the flow of information. Although some development partner actors were as strategically located, none had the same level of authority or trust as was imbued by being a member of the government civil service. The entrepreneur's mid-level rank in the health ministry may have encouraged him/her to invest political capital and take risks that would not have been feasible or attractive to a
Full Text Available Abstract Background Infant mortality rates (IMR remain high in many sub-Saharan African countries, especially in rural settings where access to health services may be limited. Studies in such communities can provide relevant data on the burden of and risk factors for infant death. We measured IMR and explored risk factors for infant death in a cohort of children born in Banfora Health District, a rural area in South-West Burkina Faso. Methods A prospective community-based cohort study was nested within the PROMISE-EBF trial (NCT00397150 in 24 villages of the study area. Maternal and infant baseline characteristics were collected at recruitment and after birth, respectively. Home visits were conducted at weeks 3, 6, 12, 24 and 52 after birth. Descriptive statistics were calculated using robust standard errors to account for cluster sampling. Cox multivariable regression was used to investigate potential risk factors for infant death. Results Among the 866 live born children included in the study there were 98 infant deaths, yielding an IMR of 113 per 1000 live births (95% CI: 89–143. Over 75% of infant deaths had occurred by 6 months of age and the post neonatal infant mortality rate was 67 per 1000 live births (95% CI: 51–88. Infections (35% and preterm births complications (23% were the most common probable causes of death by 6 months. Multivariable analyses identified maternal history of child death, polygyny, twin births and poor anthropometric z-scores at week-3 as factors associated with increased risk of infant death. Conclusions We observed a very high IMR in a rural area of Burkina Faso, a country where 75% of the population lives in rural settings. Community-based health interventions targeting mothers and children at high risk are urgently needed to reduce the high burden of infant deaths in these areas.

Background In most African countries, indigents treated at public health centres are supposed to be exempted from user fees. In Africa, most of the available knowledge has to do with targeting processes in rural areas, and little is known about how to select the worst-off in an urban area. In rural communities of Burkina Faso, trials of participatory community-based selection of indigents have been effective. However, the process for selecting indigents in urban areas is not yet clear.

Full Text Available Abstract Background There is a scarcity of reliable data on perinatal mortality (PNM in Sub-Saharan Africa. The PROMISE-EBF trial, during which we promoted exclusive breastfeeding, gave us the opportunity to describe the epidemiology of PNM in Banfora Health District, South-West in Burkina Faso. Study objectives To measure the perinatal mortality rate (PNMR in the PROMISE-EBF cohort in Banfora Health District and to identify potential risk factors for perinatal death. Methods We used data collected prospectively during the PROMISE-EBF-trial to estimate the stillbirth rate (SBR and early neonatal mortality rate (ENMR. We used binomial regression with generalized estimating equations to identify potential risk factors for perinatal death. Results 895 pregnant women were enrolled for data collection in the EBF trial and followed-up to 7 days after birth. The PNMR, the SBR and the ENMR, were 79 per 1000 (95% CI: 59-99, 54 per 1000 (95% CI: 38-69 and 27 per 1000 (95% CI: 9-44, respectively. In a multivariable analysis, nulliparous women (RR = 2.90, 95% CI: 1.6-5.0, primiparae mothers (RR = 2.20, 95% CI: 1.2-3.9, twins (RR = 4.0, 95% CI: 2.3-6.9 and giving birth during the dry season (RR = 2.1 95% CI: 1.3-3.3 were factors associated with increased risk of perinatal death. There was no evidence that risk of perinatal death differed between deliveries at home and at a health centre Conclusion Our study observed the highest PNMR ever reported in Burkina. There is an urgent need for sustainable interventions to improve maternal and newborn health in the country.
Full text: Burkina Faso is among the poorest countries in the world. The energy situation in Burkina Faso is among the most critical issues which need to be addressed in the country. The electrical power grid is insufficient and only available in urban centers. Consequently wood and charcoal is used in order to meet the basic needs for heating, cooking, and lightning by the majority of the population. The resulting overuse of natural energy resources in Burkina Faso has been causing massive deforestation and desertification on the one hand and on the other hand scarcity in fuel wood availability. According to a recent feasibility study of the GTZ, biogas is thought to be one of the most sustainable solutions for developing energy self sufficiency in rural areas of Burkina Faso. Biogas is not a new concept in Burkina Faso, as the first biogas plants were already installed in the 70's. Recently a national biogas program and the activity of various NGOs lead to a rejuvenation of attempts to establish biogas in Burkina Faso. Although biogas has a long history in Burkina Faso, no significant breakthrough of this technology has happened so far. None of the biogas plants built during the last 40 years have been operational for a long time. This contribution presents a study aimed to analyze the partial success and failures of the attempts to install biogas plants so far. The study was conducted in May 2009 as part of a project for a model application of the technology in the frame of University cooperation between Austria (University of Innsbruck) and Burkina Faso (Universite Polytechnique du Bobo Dioulasso). During the field study four sites of existing biogas plants were visited, five interviews with experts conducted and two focus groups with potential users in a rural setting were conducted. The systemic approach, including technical as well as socioeconomic aspects, yielded a wealth of factors which can potentially influence the success of biogas projects in
Full Text Available Abstract Background In the rural areas of sub-Saharan Africa, the majority of young children affected by malaria have no access to formal health services. Home treatment through mothers of febrile children supported by mother groups and local health workers has the potential to reduce malaria morbidity and mortality. Methods A cluster-randomized controlled effectiveness trial was implemented from 2002–2004 in a malaria endemic area of rural Burkina Faso. Six and seven villages were randomly assigned to the intervention and control arms respectively. Febrile children from intervention villages were treated with chloroquine (CQ by their mothers, supported by local women group leaders. CQ was regularly supplied through a revolving fund from local health centres. The trial was evaluated through two cross-sectional surveys at baseline and after two years of intervention. The primary endpoint of the study was the proportion of moderate to severe anaemia in children aged 6–59 months. For assessment of the development of drug efficacy over time, an in vivo CQ efficacy study was nested into the trial. The study is registered under http://www.controlled-trials.com (ISRCTN 34104704. Results The intervention was shown to be feasible under program conditions and a total of 1.076 children and 999 children were evaluated at baseline and follow-up time points respectively. Self-reported CQ treatment of fever episodes at home as well as referrals to health centres increased over the study period. At follow-up, CQ was detected in the blood of high proportions of intervention and control children. Compared to baseline findings, the prevalence of anaemia (29% vs 16%, p P. falciparum parasitaemia, fever and palpable spleens was lower at follow-up but there were no differences between the intervention and control group. CQ efficacy decreased over the study period but this was not associated with the intervention. Discussion The decreasing prevalence of malaria

Abstract Background User fees were generalized in Burkina Faso in the 1990 s. At the time of their implementation, it was envisioned that measures would be instituted to exempt the poor from paying these fees. However, in practice, the identification of indigents is ineffective, and so they do not have access to care. Thus, a community-based process for selecting indigents for user fees exemption was tested in a district. In each of the 124 villages in the catchment areas of ten health centre...
Full Text Available Background: Obesity is a global epidemic that affects both developed and developing countries. According to World Health Organization (WHO, in 2014, over 1.9 billion adults were overweight. Burkina Faso, like other countries, faces the problem of obesity, with a prevalence of 7.3%. The main cause is excessive intake of caloric foods combined with low physical activity, although genetic, endocrine and environmental influences (pollution can sometimes be predisposing factors. This metabolic imbalance often leads to multiple pathologies (heart failure, Type II diabetes, cancers, etc.. Drugs have been developed for the treatment of these diseases; but in addition to having many side effects, locally these products are not economically accessible to the majority of the population. Burkina Faso, like the other countries bordering the Sahara, has often been confronted in the past with periods of famine during which populations have generally used anorectic plants to regulate their food needs. This traditional ethnobotanical knowledge has not been previously investigated. An ethnobotanical survey was conducted in Burkina Faso in the provinces of Seno (North and Nayala (Northwest to list the plants used by local people as an anorectic and/or fort weight loss. Methods: The survey, conducted in the two provinces concerned traditional healers, herbalists, hunters, nomads and resourceful people with knowledge of plants. It was conducted over a period of two months and data were collected following a structured interview with the respondents. The approach was based on dialogue in the language of choice of the respondent and the use of a questionnaire. The data have been structured and then statistically analyzed. Results: The fifty-five (55 respondents of the survey were aged between 40 and 80 years. Sixty-one (61 plant species, belonging to thirty-one (31 families were listed as appetite suppressants and/or for their anti-obesity properties. The main

This brief report, drawing from a multi-year effort by the U.S. Agency for International Development (USAID) Famine Early Warning Systems Network (FEWS NET), examines recent trends in rainfall and air temperatures. These analyses are based on quality controlled station observations. Conclusions: * Summer rains have remained steady over the past 20 years, but remain 15 percent below the 1920-69 average. * Temperatures have increased by 0.6° Celsius since 1975, amplifying the effect of droughts. * The amount of farmland per person is low, and declining. * Burkina Faso has offset rapid population growth with improved yields. * Continued yield growth would maintain current levels of per capita food production.
This document is about the evaluation of the energy sector in Burkina Faso. It reports about the main issues of energy: poverty of the households, the lack of fund to finance the sector, desertification...The main resources of energy are firewood, fuel and electricity. The energy needs of Burkina Faso are related to the cooking of food, with liquid fuels intended for the railway transport and fuels used in industry and for the production of electricity. With regard to the transport sector, there is currently no possibility of substitution for the fuel, except the use of ethanol diluted in the gasoline. At the industrial level, agro-industrial, bagasse and the other residues constitute right now the independent source of energy for the production of industrial heat as well as for that of electricity. For the public network of electricity supply, the production rests exclusively on diesel power stations. Regarding the immense needs for its populations in energy, Burkina has only very limited resources. The biomass used for domestic needs cannot continuously ensure the households with the necessary energy supply for food cooking. As for the agro-industrial residues, they cannot reduce the industrial consumption of fuels. There are also hydraulic resources whose conscientious exploitation could contribute to decrease the fuel consumption in terms of electricity. In sum, it would be necessary to improve the regulation as regards firewood supply, to promote the use of improved hearths with wood, to plan the fuel supplies and to assist the SONABEL in the electric production capacities reinforcement of its fuel-based power stations

Full Text Available Abstract Introduction African-American black men race is one of non-modifiable risk factors confirmed for prostate cancer. Many studies have been done in USA among African- American population to evaluate prostate cancer disparities. Compared to the USA very few data are available for prostate cancer in Sub-Saharan African countries. The objective of this study was to describe incident prostate cancer (PC diagnosis characteristics in Burkina Faso (West Africa. Methods We performed a prospective non randomized patient’s cohort study of new prostate cancer cases diagnosed by histological analysis of transrectal prostate biopsies in Burkina Faso. Study participants included 166 patients recruited at the urology division of the university hospital of Ouagadougou. Age of the patients, clinical symptoms, digital rectal examination (DRE result, serum prostate-specific antigen (PSA level, histological characteristics and TNM classification were taking in account in this study. Results 166 transrectal prostate biopsies (TRPB were performed based on high PSA level or abnormal DRE. The prostate cancer rate on those TRPB was 63, 8 % (n=106. The mean age of the patients was 71, 5 years (52 to 86. Urinary retention was the first clinical patterns of reference in our institution (55, 7 %, n = 59. Most patients, 56, 6 % (n = 60 had a serum PSA level over than 100 ng/ml. All the patients had adenocarcinoma on histological study of prostate biopsy cores. The majority of cases (54, 7 % n = 58 had Gleason score equal or higher than 7. Conclusion Prostate cancer is diagnosed at later stages in our country. Very high serum PSA level and poorly differentiated tumors are the two major characteristics of PC at the time of diagnosis.
Full Text Available Burkina Faso is endemic with soil-transmitted helminth infections. Over a decade of preventive chemotherapy has been implemented through annual lymphatic filariasis (LF mass drug administration (MDA for population aged five years and over, biennial treatment of school age children with albendazole together with schistosomiasis MDA and biannual treatment of pre-school age children through Child Health Days. Assessments were conducted to evaluate the current situation and to determine the treatment strategy for the future.A cross-sectional assessment was conducted in 22 sentinel sites across the country in 2013. In total, 3,514 school age children (1,748 boys and 1,766 girls were examined by the Kato-Katz method. Overall, soil-transmitted helminth prevalence was 1.3% (95% CI: 1.0-1.8% in children examined. Hookworm was the main species detected, with prevalence of 1.2% (95% CI: 0.9-1.6% and mean egg counts of 2.1 epg (95% CI: 0-4.2 epg. Among regions, the Centre Ouest region had the highest hookworm prevalence of 3.4% (95% CI: 1.9-6.1% and mean egg counts of 14.9 epg (95% CI: 3.3-26.6 epg. A separate assessment was conducted in the Centre Nord region in 2014 using community-based cluster survey design during an LF transmission assessment survey (TAS. In this assessment, 351 children aged 6-7 years and 345 children aged 10-14 years were examined, with two cases (0.6% (95% CI: 0.2-2.1% and seven cases (2.0% (95% CI: 1.0-4.1% of hookworm infection was identified respectively. The results using both age groups categorized the region to be 2% to <10% in STH prevalence according to the pre-defined cut-off values.Through large-scale preventive chemotherapy, Burkina Faso has effectively controlled STH in school age children in the country. Research should be conducted on future strategies to consolidate the gain and to interrupt STH transmission in Burkina Faso. It is also demonstrated that LF TAS provides one feasible and efficient platform to assess the

In West Africa, health system funding rarely involves cross-subsidization among population segments. In some countries, a few community-based or professional health insurance programs are present, but coverage is very low. The financial principles underlying universal health coverage (UHC) sustainability and solidarity are threefold: 1) anticipation of potential health risks; 2) risk sharing and; 3) socio-economic status solidarity. In Burkina Faso, where decision-makers are favorable to national health insurance, we measured endorsement of these principles and discerned which management configurations would achieve the greatest adherence. We used a sequential exploratory design. In a qualitative step (9 interviews, 12 focus groups), we adapted an instrument proposed by Goudge et al. (2012) to the local context and addressed desirability bias. Then, in a quantitative step (1255 respondents from the general population), we measured endorsement. Thematic analysis (qualitative) and logistic regressions (quantitative) were used. High levels of endorsement were found for each principle. Actual practices showed that anticipation and risk sharing were not only intentions. Preferences were given to solidarity between socio-economic status (SES) levels and progressivity. Although respondents seemed to prefer the national level for implementation, their current solidarity practices were mainly focused on close family. Thus, contribution levels should be set so that the entire family benefits from healthcare. Some critical conditions must be met to make UHC financial principles a reality through health insurance in Burkina Faso: trust, fair and mandatory contributions, and education. PMID:26803656
Full Text Available Abstract Background Financial barriers are a recognized major bottleneck of access and use of health services. The aim of this study was to assess effectiveness of a community based health insurance (CBHI scheme on utilization of health services as well as on mortality and morbidity. Methods Data were collected from April to December 2007 from the Nouna’s Demographic Surveillance System on overall mortality, utilization of health services, household characteristics, distance to health facilities, membership in the Nouna CBHI. We analyzed differentials in overall mortality and selected maternal health process measures between members and non-members of the insurance scheme. Results After adjusting for covariates there was no significant difference in overall mortality between households who could not have been members (because their area was yet to be covered by the stepped-wedged scheme, non-members but whose households could have been members (areas covered but not enrolled, and members of the insurance scheme. The risk of overall mortality increased significantly with distance to health facility (35% more outside Nouna town and with education level (37% lower when at least primary school education achieved in households. Conclusion There was no statistically significant difference in overall mortality between members and non-members. The enrolment rates remain low, with selection bias. It is important that community based health insurances, exemptions fees policy and national health insurances be evaluated on prevention of deaths and severe morbidities instead of on drop-out rates, selection bias, adverse selection and catastrophic payments for health care only. Effective social protection will require national health insurance.

A total of 6440 female sheep from Burkina Faso were scored for seven body measurements and four qualitative morphological traits. Sampling included the three main environmental areas and sheep breeds of Burkina Faso: the Sahel area (Burkina-Sahel sheep), the Sudan- Sahel area (Mossi sheep) and the Sudan area (Djallonke sheep). Canonical analyses showed that differences in body measurements between the Sudan and the Sudan-Sahel sheep were small even though most body traits showed higher average values in the Burkina-Sahel sheep: the shortest Mahalanobis distance was found between the Sudan and the Sudan-Sahel populations (1.54), whilst that between the Sudan and the Sahelian populations was the largest (7.88). Discriminant analysis showed that most Sudan (Djallonke) individuals (60.85%) were classified as Sudan-Sahel (Mossi) individuals whilst most Burkina-Sahel individuals were classified into their environmental area of sampling (89.5%). Correspondence analyses indicated that the Burkina-Sahel sheep population clustered together with dropping ears, black and brown colour patterns and presence of wattles, the Sudan sheep were closely associated with long hair and vertical and curled ears and that the Sudan-Sahel sheep did not have clear associations with qualitative phenotypic traits. At the morphological level, the Sudan-Sahel (Mossi) sheep population can be considered a geographical subpopulation belonging to the Djallonke breed, showing some particularities, namely larger body size, due to the particular environmental condition of the area in which it is managed and a continuous gene flow from Sahelian sheep, The information reported in this study will be the basis for the establishment of further characterization, conservation and selection strategies for Burkina Faso sheep.

At the time of their implementation, it was envisioned that measures would be instituted to exempt the poor from paying these fees. However, in practice, the identification of indigents is ineffective, and so they do not have access to care. Thus, a community-based process for selecting indigents for user fees exemption was tested in a district. In each of the 124 villages in the catchment areas of ten health centres, village committees proposed lists of indigents that were then validated by the health centres' management committees. The objective of this study is to evaluate the effectiveness of this community-based selection. Methods An indigent-selection process is judged effective if it minimizes inclusion biases and exclusion biases. The study compares the levels of poverty and of vulnerability of indigents selected by the management committees (n = 184 with: 1 indigents selected in the villages but not retained by these committees (n = 48; ii indigents selected by the health centre nurses (n = 82; and iii a sample of the rural population (n = 5,900. Results The households in which the three groups of indigents lived appeared to be more vulnerable and poorer than the reference rural households. Indigents selected by the management committees and the nurses were very comparable in terms of levels of vulnerability, but the former were more vulnerable socially. The majority of indigents proposed by the village committees who lived in extremely poor households were retained by the management committees. Only 0.36% of the population living below the poverty threshold and less than 1% of the extremely poor population were selected. Conclusions The community-based process minimized inclusion biases, as the people selected were poorer and more vulnerable than the rest of the population. However, there were significant exclusion biases; the selection was very restrictive

Lymphatic filariasis (LF) is a parasitic disease that is endemic throughout sub-Saharan Africa, infecting approximately 40 million people. In Burkina Faso, mass drug administration (MDA) for LF with ivermectin and albendazole has been ongoing since 2001, and by 2006 all endemic health districts were receiving MDA with a therapeutic coverage of at least 65%. As MDA activities scale down, the focus is now on targeting areas where LF transmission persists with alternative elimination strategies....

Burkina Faso is a State with Small Quantity Protocol and its Additional Protocol (INFCIRC/618/Add.1) interred into force on the 17 of April 2003. Burkina Faso is involved in the Agency nuclear security activities through many multilateral and bilateral agreements; and obviously, Safeguards Agreements. The International Atomic Energy Agency (IAEA)'s statutes have been ratified by Burkina Faso in 1998. The country became IAEA membership since 14 September 1998 (number of accession: 128). The basic law relating to radiation protection and nuclear safety has been voted by the National Assembly on 26 April 2005. This law is the legal basis that allowed the creation of the National Regulatory Authority for Radiation protection and Nuclear safety (ARSN). The global aim is to regulate activities involving nuclear materials or radioactive sources, to control the traffic of such materials and to manage radioactive waste within the country. ARSN is the national regulatory body competent for the control of the better use of ionizing radiation sources. This authority received mandate to establish and maintain an SSAC in accordance with the IAEA guidance. For the ARSN to be effective in its responsibilities, all activities involving radiation exposure are subjected to regulatory control by a system of notification, authorization by registration or licensing and inspection. Two separated infrastructures are dealing with nuclear energy. The first one, called Autorite Nationale de Radioprotection et de Surete Nucleaire (ARSN) ) is acting as a regulator. The second one, Secretariat Technique a l'Energie Nucleaire (STEA) acts as a promoter. During the Santa Fe International Training Course, USA may 2008, we agreed the Burkina Faso SSAC to be implemented by ARSN. The STEA should be involved by sending officially reports and declarations (received from ARSN) to the IAEA, through the National Liaison Officer. In order to maintain the SSAC, physical inventories are conducted, regularly
Full Text Available Background: Micro health insurance schemes have been implemented across developing countries as a means of facilitating access to modern medical care, with the ultimate aim of improving health. This effect, however, has not been explored sufficiently. Objective: We investigated the effect of enrolment into community-based health insurance on mortality in children under 5 years of age in a health and demographic surveillance system in Nouna, Burkina Faso. Design: We analysed the effect of health insurance enrolment on child mortality with a Cox regression model. We adjusted for variables that we found to be related to the enrolment in health insurance in a preceding analysis. Results: Based on the analysis of 33,500 children, the risk of mortality was 46% lower in children enrolled in health insurance as compared to the non-enrolled children (HR=0.54, 95% CI 0.43–0.68 after adjustment for possible confounders. We identified socioeconomic status, father's education, distance to the health facility, year of birth, and insurance status of the mother at time of birth as the major determinants of health insurance enrolment. Conclusions: The strong effect of health insurance enrolment on child mortality may be explained by increased utilisation of health services by enrolled children; however, other non-observed factors cannot be excluded. Because malaria is a main cause of death in the study area, early consultation of health services in case of infection could prevent many deaths. Concerning the magnitude of the effect, implementation of health insurance could be a major driving factor of reduction in child mortality in the developing world.
Full Text Available The use of the amaranths as vegetables is developed in Burkina Faso. Most known are Amaranthus dubius Mart. Ex. Thell, Amaranthus graecizans L., Amaranthus hybridus L. and Amaranthus viridis L. A. hybridus is most used and abundantly cultivated, however the others are more or less wild. Theaim of the present study was to investigate the nutraceutical potentialities of four Amaranthus species from Burkina Faso. The aqueous decoction extract of the four species contains the highest ofpolyphenols, flavonoids,flavonols and proteins contents. The aqueous decoction extracts were used for the evaluation of the antioxidant activity and xanthine oxidase inhibitory potentiality. The A. dubius showed the most potent antioxidant activity with a CE50 of 1.26±0.46, mgm2 the β-carotene bleaching method. A. hybridus showed the most potent antioxidant activity (66.99±1.65 μmolAEAC/g in the DPPH radical scavengingmethod. The aqueous extracts of the four speciesshowed weak inhibition of the xanthine oxidaseat the concentration of 200 μg/mL.The four Amaranthus species are rich in microelements (Na, K, Ca, Mg, P, Fe, Mn, Zn and Cu and carotenoids compounds. The antinutritionals factors were also quantified. The oxalate amount in these species is fairly high. The highest minerals contents and the antioxidant activity of the amaranths could explain theirlarge use by all the socioeconomic strata of the population.These plants would constitute a source of dietetic antioxidants.

Full Text Available Abstract Background In sub-Saharan Africa, women must overcome numerous barriers when they need modern healthcare. Respect of gender norms within the household and the community may still influence women's ability to obtain care. A lack of gender-sensitive instruments for measuring women's ability to overcome barriers compromises attempts to adequately quantify the burden and risk of exclusion they face when seeking modern healthcare. The aim of this study was to create and validate a synthetic measure of women's access to healthcare from a publicly available and possibly internationally comparable population-based survey. Method Seven questionnaire items from the Burkina Faso 2003 DHS were combined to create the index. Cronbach's alpha coefficient was used to test the reliability of the index. Exploratory factor analyses (EFA and confirmatory factor analyses (CFA were applied to evaluate the factorial structure and construct validity of the index while taking into account the hierarchical structure of the data. Results The index has a Cronbach's alpha of 0.75, suggesting adequate reliability. In EFA, three correlated factors fitted the data best. In CFA, the construct of perceived ability to overcome barriers to healthcare seeking emerged as a second-order latent variable with three domains: socioeconomic barriers, geographical barriers and psychosocial barriers. Model fit indices support the index's global validity for women of reproductive age in Burkina Faso. Evidence for construct validity comes from the finding that women's index scores increase with household living standard. Conclusion The DHS items can be combined into a reliable and valid, gender-sensitive index quantifying reproductive-age women's perceived ability to overcome barriers to healthcare seeking in Burkina Faso. The index complies conceptually with the sector-cross-cutting capability approach and enables measuring directly the perceived access to healthcare. Therefore it
Le Burkina Faso connaît une urbanisation relativement modérée. En effet, selon le recensement de décembre 1985, le taux d'urbanisation s'élevait à 13,6% et cela en tenant compte des seize centres secondaires de plus de 10.000 habitants. En se basant sur les 119 localités de plus de 5.000 habitants, ce taux dépasse à peine 27%. Or des pays tels que la Côte d'Ivoire, le Ghana et le Sénégal présentaient au même moment des taux de 45 à 50%. Cependant la taille et le nombre des centres urbains ne ...
Full Text Available This study analyzes public funding in the agricultural sector in Burkina Faso and assesses its impact on agricultural growth. Based on data collected from several sources (finance acts over the period 1983-2008, Automated Prediction Instrument (IPA, World Bank and National agricultural statistics over 26 years (from 1983 to 2008, the agricultural production has been modelled by using an error correction model and Cobb-Douglas function. The econometric analysis results show that public funding has a positive impact on agricultural production in the short term. A 9% growth rate of public funding over the period 2009-2015, causes an average agricultural production of 6.75% over the period. So, it is necessary for the State to increase funding in the agricultural sector to achieve a better growth of the domestic production and to meet the Millennium Development Goals regarding hunger reduction over the period 2009-2015.

With the "green economy" being promoted as a path to sustainable development and food security within the African continent, the influx of agricultural land is proliferating at a rapid pace often replacing natural savannah forests. Where agriculture is primarily rainfed, the possible adverse impacts of agricultural land influx on rainfall occurrences in water-limited areas such as West Africa warrant attention. Using field observations complemented by model calculations in southeastern Burkina Faso, the main causes of a 10-30% suppressed daytime rainfall recorded over agricultural fields when referenced to natural savannah forests are examined. Measurements and model runs reveal that the crossing of the mixed layer height and lifting condensation levels, a necessary condition for cloud formation and subsequent rainfall occurrence, was 30% more frequent above the natural savannah forest. This increase in crossing statistics was primarily explained by increases in measured sensible heat flux above the savannah forest rather than differences in lifting condensation heights.

Two sites (villages of Sampiéri and Bandougou) with contrasted pedo-climatic conditions were selected.
Full Text Available Abstract Background There is concern about an increasing infiltration of markets by substandard and fake medications against life-threatening diseases in developing countries. This is particularly worrying with regard to the increasing resistance development of Plasmodium falciparum against affordable anti-malarial medications, which has led to a change to more expensive drugs in most endemic countries. Methods A representative sample of modern anti-malarial medications from licensed (public and private pharmacies, community health workers and illicit (market and street vendors, shops sources has been collected in the Nouna Health District in north-western Burkina Faso in 2006. All drugs were tested for their quality with the standard procedures of the German Pharma Health Fund-Minilab. Detected low standard drugs were re-tested with European Pharmacopoeia 2.9.1 standards for disintegration and ultraviolet-visible spectroscopy at the laboratory of the Heidelberg University for confirmation. Results Overall, 86 anti-malarial drug samples were collected, of which 77 samples have been included in the final analysis. The sample consisted of 39/77 (50% chloroquine, 10/77 (13% pyrimethamine-sulphadoxine, 9/77 (12% quinine, 6/77 (8% amodiaquine, 9/77 (12% artesunate, and 4/77 (5% artemether-lumefantrine. 32/77 (42% drug samples were found to be of poor quality, of which 28 samples failed the visual inspection, nine samples had substandard concentrations of the active ingredient, four samples showed poor disintegration, and one sample contained non of the stated active ingredient. The licensed and the illicit market contributed 5/47 (10.6% and 27/30 (90.0% samples of substandard drugs respectively. Conclusion These findings provide further evidence for the wide-spread existence of substandard anti-malarial medications in Africa and call for strengthening of the regulatory and quality control capacity of affected countries, particularly in view of the

Our aim was to investigate the key determinants of induced abortion in a sample of women who sought postabortion care. Materials and methods: A cross-sectional household survey was carried out from February to September 2012 in Ouagadougou, Burkina Faso. Data of 37 women who had had an induced abortion and 267 women who had had a spontaneous abortion were prospectively collected on sociodemographic characteristics, pregnancy and birth history, abortion experience, including previous abortion experience, and selected clinical information, including the type of abortion. A two-step regression analysis consisting of a univariate and a multivariate logistic regression was run on Stata version 11.2 in order to identify the key determinants of induced abortion. Results: The findings indicated that 12% of all abortions were certainly induced. Three key factors were significantly and positively associated with the probability of having an induced abortion: whether the woman reported that her pregnancy was unwanted (odds ratio [OR] 10.45, 95% confidence interval [CI] 3.59–30.41; whether the woman reported was living in a household headed by her parents (OR 6.83, 95% CI 2.42–19.24; and if the woman reported was divorced or widowed (OR 3.47, 95
Full Text Available Abstract Background In the absence of large scale, organized vector control programmes, individual protective measures against mosquitoes are essential for reducing the transmission of diseases like malaria. Knowledge of the types and effectiveness of mosquito control methods used by households can aid in the development and promotion of preventive measures. Methods A matched, population-based case control study was carried out in the semi-urban region of Nouna, Burkina Faso. Surveys and mosquito captures were conducted for each participating household. Data were analysed using conditional logistic regression and Pearson's product-moment correlations. Results In Nouna, Burkina Faso, the main types of reported mosquito control measures used included sleeping under bed nets (insecticide-treated and untreated and burning mosquito coils. Most of the study households kept animals within the compound or house at night. Insecticide house sprays, donkeys, rabbits and pigs were significantly associated with a reduced risk of malaria only in univariate analyses. Conclusion Given the conflicting results of the effects of zooprophylaxis from previous studies, other community-based preventive measures, such as bed nets, coils and insecticide house-spraying, may be of more benefit.

This paper describes the status quo of the power sector in Burkina Faso, its limitations, and develops a new methodology that through spatial analysis processes with the aim to provide a possible pathway for universal electricity access. Following the SE4All initiative approach, it recommends the more extensive use of distributed renewable energy systems to increase access to electricity on an accelerated timeline. Less than 5% of the rural population in Burkina Faso have currently access to electricity and supply is lacking at many social structures such as schools and hospitals. Energy access achievements in Burkina Faso are still very modest. According to the latest SE4All Global Tracking Framework (2015), the access to electricity annual growth rate in Burkina Faso from 2010 to 2012 is 0%. The rural electrification strategy for Burkina Faso is scattered in several electricity sector development policies: there is a need of defining a concrete action plan. Planning and coordination between grid extension and the off-grid electrification programme is essential to reach a long-term sustainable energy model and prevent high avoidable infrastructure investments. This paper goes into details on the methodology and findings of the developed Geographic Information Systems tool. The aim of the dynamic planning tool is to provide support to the national government and development partners to define an alternative electrification plan. Burkina Faso proves to be paradigm case for the methodology as its national policy for electrification is still dominated by grid extension and the government subsidising fossil fuel electricity production. However, the results of our analysis suggest that the current grid extension is becoming inefficient and unsustainable in order to reach the national energy access targets. The results also suggest that Burkina Faso’s rural electrification strategy should be driven local renewable resources to power distributed mini-grids. We find that
former agricultural work. 54% of women went into agriculture again and 40% sought employment in the tertiary sector. About 3/4 of the funds saved by migrants are spent on consumer goods and gifts. A small proportion of savings is utilized for productive ends. The return o migrants has little social effect on their villages but migrants are increasing their investments in agricultural equipment and supplies and in construction of community facilities. Despite attempts to establish intergovernmental conventions to regulate the remittances to Burkina Faso from the countries where migrants are employed, the arrangements have been successful. Estimates of the amount of remittances are based on incomplete information. PMID:12343341
Full Text Available AbstractThis paper examines entry into consensual unions versus marriages in BurkinaFaso, a topic that has received little attention to date in sub-Saharan Africa.Changes in marriage behaviors may entail or reflect profound changes in familyorganization, gender relations and fertility and, to the extent that consensualunions are relatively transitory and lead to more sexual partners, they may beassociated with greater sexual risks including HIV. The determinants of newunions being consensual are estimated from national family-life type survey datathat provide information on the timing of different types of marriages and thestart of cohabitation. While consensual unions are not new to the country, theyappear to be changing in nature and have been growing more common overtime especially in urban areas. They are also more popular among men andwomen with greater schooling or who began cohabiting while living outside thecountry, and for women who have previously lived in union.RésuméCet article compare les entrées en unions libres avec et les mariages au BurkinaFaso, un sujet ayant reçu peu d'attention en Afrique sub-saharienne jusqu'àprésent.

This study empirically establishes the direction of causality between electricity consumption and economic growth in Burkina Faso for the period 1968-2003. The bounds test yields evidence of cointegration between electricity consumption, GDP, and capital formation when electricity consumption and GDP are used as dependent variable. Causality results indicate that there is no significant causal relationship between electricity consumption and investment. Estimates, however, detect in the long-run a bidirectional causal relationship between electricity use and real GDP. There is also evidence of a positive feedback causal relationship between GDP and capital formation. Burkina Faso is therefore an energy dependent country. It is also a country in which electricity consumption is growing with the level of income. All of this shows that electricity is a significant factor in socio-economic development in Burkina Faso; as such, energy policy must be implemented to ensure that electricity generates fewer potential negative impacts.
Full Text Available The northern distribution limit of tsetse flies was updated in Burkina Faso and compared to previous limits to revise the existing map of these vectors of African trypanosomiases dating from several decades ago. From 1949 to 2009, a 25- to 150-km shift has appeared toward the south. Tsetse are now discontinuously distributed in Burkina Faso with a western and an eastern tsetse belt. This range shift can be explained by a combination of decreased rainfall and increased human density. Within a context of international control, this study provides a better understanding of the factors influencing the distribution of tsetse flies.

Post-stroke epilepsy (PSE) is defined as "recurrent seizures following stroke with confirmed diagnosis of epilepsy". Our objective was to describe the epidemiological, clinical and therapeutic PSE aspects at the Yalgado Ouedraogo Teaching Hospital, the main reference centre for neurological conditions in Burkina Faso. We conducted a retrospective study from January 2006 to December 2014. The data on thirty-two (32) cases of PSE was collected from a total of 1616 patients hospitalized for stroke, representing a rate of 1.98%. The patients' ages ranged from 25 to 77years old with a mean age of 58±10.39. There were 21 men and 11 women, with a gender ratio of 1.9. The time of occurrence of PSE ranged between 10 and 3600days (10years). The brain CT scan helped distinguish the different subtypes of stroke. Sixty-four percent (64%) of the cases experienced ischemic stroke and 36% of the cases cerebral hemorrhage. With regard to medical treatment, 23 patients received monotherapy, and 4 patients dual therapy. Exactly 96.87% of seizures were stabilized during the hospitalization period. PSE is a symptomatic type of epilepsy occurring during stroke sequelae. It is important not to lose sight of this before the occurrence of any focal or generalized seizure after a stroke.

An extensive survey on household expenditures in Ouagadougou, the capital of Burkina Faso, was used to analyze the factors determining urban household energy choices using a multinomial logit model. Wood-energy remains the preferred fuel of most urban households in the country; though rational, the choice is not sustainable as it portends a threat to the savanna woodlands and the economy. Many important policies have been adopted by public authorities to minimize household wood-energy consumption and to substitute it by alternative fuel. Despite the magnitude of all these policies, the depletion rate of the forest resource is increasing. A kind of inertia is thus observed for household preferences for cooking fuel. This model analyzes the sociological and economic variables of household energy preferences for cooking in Ouagadougou. The analyses show that the inertia of household cooking energy preferences are due to poverty factors such as low income, poor household access to electricity for primary and secondary energy, low house standard, household size, high frequency of cooking certain meals using woodfuel as cooking energy. The descriptive analyses show that the domestic demand for wood-energy is strongly related to household income. The firewood utilization rate decreases with increasing household income. In other words, this fuel appears as a 'transition good' for these households which aim for other sources of energy for cooking that are more adapted for urban consumption. This implies that a price subsidy policy for liquid petroleum gas (LPG) and its cook stoves could significantly decrease the utilization rate of wood-energy

Full Text Available Striga hermonthica (Del. Benth. is an important constraint to cereal crop production in Burkina Faso, of which sorghum (Sorghum bicolor L. Moench is the most important component. Native Fusarium species to use as bio-control agents to S. hermonthica has been investigated. Fifty one Fusarium isolates obtained from diseased plants of S. hermonthica were evaluated for their pathogenicity against Striga under controlled environmental conditions. Of 51 Fusarium isolates, 14 were pathogenic to S. hermonthica but their virulence differed. These 14 isolates were evaluated for their effects on Striga seed germination in the laboratory and their ability to kill emerged Striga plants growing in greenhouse pots. Spores of Fusarium sp. isolates 150a-M, 125b-Za, 6-Fa, Fusarium equiseti isolates 5-Kou, 31-Kom, 32-Or, 13-Ba and Fusarium oxysporum isolate 34-Fo reduced Striga germination by 78 to 96% compared to the untreated control. The study showed that at the rate of 33 mg mL-1, metabolites of Fusarium sp. isolates 125b-Za, 6-Fa, F. equiseti 5-Kou and F. oxysporum 34-Fo prevented Striga seed germination. In addition to these four isolates, Fusarium sp. isolates 141b-O, 150a-M and F. equiseti isolate 32-Or were effective at 67 mg mL-1. Percentage of Striga mortality ranged from 17-37% between 14 and 28 days after inoculation with spores of F. oxysporum 34-Fo and F. equiseti 5-Kou. Striga dry biomass was reduced by 84 and 78% for the respective isolates compared to the untreated control with Striga. Sorghum yield was improved by 84 and 99% with Fusarium sp. 6-Fa and F. oxysporum 34-Fo, respectively, compared to the control without Striga. The use of Fusarium spores and metabolites against Striga offers different possibilities of bio-herbicides formulation that can be combined with other controls methods in the integrated Striga management. Further studies will be carried out under field conditions to assess the efficacy and safety of these Fusarium isolates to

We estimate the effects of changes in cotton adoption on children's schooling and child labor in rural Burkina Faso. Cotton adoption increases household's income, leading to increased demand for schooling and reduced child labor. On the other hand, because children are productive on cotton farms, cotton adoption increases the opportunity cost of child time and the demand for child labor.

"This paper describes the emergence of improved traditional planting pits (zaï) in Burkina Faso in the early 1980s as well as their advantages, disadvantages and impact. The zaï emerged in a context of recurrent droughts and frequent harvest failures, which triggered farmers to start improving this local practice. Despair triggered experimentation and innovation by farmers. These processes were supported and complemented by external intervention. Between 1985 and 2000 substantial public inves...

Background Female genital mutilation (FGM) usually undertaken between the ages of 1-9 years and is widely practised in some part of Africa and by migrants from African countries in other parts of the world. Laws prohibit FGM in almost every country. FGM can cause immediate complications (pain, bleeding and infection) and delayed complications (sexual, obstetric, psychological problems). Several factors have been associated with an increased likelihood of FGM. In Burkina Faso, the prevalence o...

In the semi-arid environment of northern Burkina Faso the processes of wind and water erosion occur almost simultaneously and may cause severe soil degradation. Especially in the early rainy season when soils are bare and unprotected, violent winds preceding intense rainfall events result in intense sediment transport by both wind and water. This Ph.D. project aimed at quantifying and modelling wind and water erosion processes, their interaction and related nutrient flows in a Sahelian enviro...

Full Text Available In Burkina Faso, the values that serve as clinical chemistry reference ranges are those provided by European manufacturers' insert sheets based on reference of the Western population. However, studies conducted so far in some African countries reported significant differences in normal laboratory ranges compared with those of the industrialized world. The aim of this study was to determine reference values of cholesterol fractions in apparently normal adults in Burkina Faso that could be used to better assess the risks related to cardiovascular diseases. Study population was 279 healthy subjects aged from 15 to 50 years including 139 men and 140 women recruited at the Regional Center of Blood Transfusion of Ouagadougou, capital city of Burkina Faso (West Africa. Exclusion criteria based on history and clinical examination were used for defining reference individuals. The dual-step precipitation of HDL cholesterol sub-fractions using dextran sulfate was performed according to the procedure described by Hirano. The medians were calculated and reference values were determined at 2.5th and 97.5th percentiles. The median and upper ranges for total cholesterol, LDL cholesterol, total HDL cholesterol and HDL2 cholesterol were observed to be higher in women in comparison to men (p <0.05. These reference ranges were similar to those derived from other African countries but lower than those recorded in France and in USA. This underscores the need for such comprehensible establishment of reference values for limited resources countries. Our study provides the first cholesterol sub-fractions (HDL2 and HDL3 reference ranges for interpretation of laboratory results for cardiovascular risk management in Burkina Faso.

A survey of the parasites of abomasa, small, and large intestines of 94 bovines conveyed to the main slaughterhouse of Ouagadougou from the central and northern part of Burkina Faso allowed the identification of nine different worm species: Cooperia punctata, Cooperia pectinata, Haemonchus contortus, Trichostrongylus colubriformis, Bunostomum phlebotomum, Moniezia expensa, Avitellina sp., Oesophagostomum radiatum, and Trichuris sp. By far, Cooperia sp. was the most prevalent (89.4/), followed...
Based on the data of the Demographic and Health Survey, and of the Household Priority Survey, carried out in 2003, the present study, examining the factors of the HIV prevalence in Burkina Faso, provides two conclusions. Firstly, the fight against poverty is not necessarily a means of reducing at the same time in a drastic way the HIV/AIDS prevalence, an assertion based on several elements of empirical analysis. First of all, the concentration curve, measuring the « socioeconomic » inequality...

This paper explores the case for believing endogenous reforms to be more developmental than externally-imposed reforms, by drawing on the recent unorthodox experience of cotton sector reform in Burkina Faso. We address questions about reform emergence, feasibility, developmental impact, and sustainability. Our analysis, which carefully incorporates local social and political realities, suggests that the urban elites dominating the Burkinabè state favoured a particular cotton reform process, b...
The objective of this thesis is to screen for biochemical determinants in sorghum varieties cultivated in Burkina Faso to identify the best sorghum varieties to be used as source of bioactive components or for specific local foods, e.g. "tô", thin porridges for infants, granulated foods "couscous", and local beers "dolo". The results revealed that sorghum varieties have different contents of starch, amylose, amylopectin and that germination decreased more the content of amylose than amylopect...

This paper provides results from qualitative fieldwork conducted in 2010 in Burkina Faso to understand the factors that lead households to rely on traditional as opposed to modern health providers, and within modern providers, on faith-inspired as opposed to public facilities. While there is an overall preference for modern care, households still rely on traditional healers for specific health issues that they encounter. As to the choice between modern providers, faith-inspired clinics and ho...
Full Text Available BACKGROUND: Paying for health care may exclude poor people. Burkina Faso adopted the DOTS strategy implementing "free care" for Tuberculosis (TB diagnosis and treatment. This should increase universal health coverage and help to overcome social and economic barriers to health access. METHODS: Straddling 2007 and 2008, in-depth interviews were conducted over a year among smear-positive pulmonary tuberculosis patients in six rural districts of Burkina Faso. Out-of-pocket expenses (direct costs associated with TB were collected according to the different stages of their healthcare pathway. RESULTS: Median direct cost associated with TB was US$101 (n = 229 (i.e. 2.8 months of household income. Respectively 72% of patients incurred direct costs during the pre-diagnosis stage (i.e. self-medication, travel, traditional healers' services, 95% during the diagnosis process (i.e. user fees, travel costs to various providers, extra sputum smears microscopy and chest radiology, 68% during the intensive treatment (i.e. medical and travel costs and 50% during the continuation treatment (i.e. medical and travel costs. For the diagnosis stage, median direct costs already amounted to 35% of overall direct costs. CONCLUSIONS: The patient care pathway analysis in rural Burkina Faso showed substantial direct costs and healthcare system delay within a "free care" policy for TB diagnosis and treatment. Whether in terms of redefining the free TB package or rationalizing the care pathway, serious efforts must be undertaken to make "free" health care more affordable for the patients. Locally relevant for TB, this case-study in Burkina Faso has a real potential to document how health programs' weaknesses can be identified and solved.
The objective of the present study is to provide an econometric test to the relative validity of collective and unitary household behavior models, with the help of data of the 1994_95 Burkina Faso household survey. Obtained results seem to justify conclusions of noncooperative approach where the well_being of the group is partly function of the identity of the income earner, the African anthropological literature and what one observes commonly as for the functioning of households on this cont...
Abstract Background This methodological article is based on a health policy research project conducted in Burkina Faso (West Africa). Concept mapping (CM) was used as a research method to understand the local views of equity among stakeholders, who were concerned by the health policy under consideration. While this technique has been used in North America and elsewhere, to our knowledge it has not yet been applied in Africa in any vernacular language. Its application raises many issues and ce...
Danida support to energy sector in Burkina Faso was limited, until 1995, to the electricity sub-sector which has directly benefited less than 5% of the Burkinabe population. Danida made no attempt to develop renewable and local energy resources during the period 1979-1995 although 92% of primary energy supply and 98% of household energy use is met by wood fuels. During 1996 Danida's energy sector programme did, however, include support to strengthen energy policy and planning in Burkina Faso. This will address both wood fuel production systems and the development of new and alternative sources of energy. Danida is currently investigating potential co-financing of a regional traditional energy sector programme with the World Bank and the Netherlands Development Cooperation. A pilot natural forest management project will be initiated in 1997 in the Central-West and Northern Regions of Burkina Faso. A Danida-funded Projet de Developpement Rural dans le Boulgou, initiated in 1996, also includes support to the development and management of natural forest resources. (au)

This study examines variations in the performance of partic-ipatory forest management programs among four forest management groups (FMGs) in southern Burkina Faso, and assesses the factors that influence their members’ perceptions of performance through a house-hold survey of 216 members. Variations in performance scores among the FMGs were analyzed through multivariate analysis of variance while multinomial regression analysis was used to identify factors that influ-ence their perception of the performance. The results reveal significant differences in performance scores among FMGs. Members of some FMGs perceived that the participatory forest management program ena-bled them to get benefits from the sale of fuelwood while performance scores in the forest conservation and decision-making processes is gener-ally poor. The score for economic performance of FMGs in turn was related to better access to roads and markets. Group size tended to en-hance economic performance via its strong influence on annual fuelwood harvest, while the resource base appeared to be inconsequential. Mem-bers of the forest management groups perceived that large group size and group heterogeneity, particularly in terms of ethnicity, as well as knowledge and awareness of problems related to the forest environment have no influence on the performance of their respective groups. For rural communities to have a favorable disposition toward sustainable forest management, differences in member understanding of collective actions and their impact before and during the implementation of partic-ipatory forest management programs should be considered.
Full Text Available Abstract Background Introgression of Sahel livestock genes southwards in West Africa may be favoured by human activity and the increase of the duration of the dry seasons since the 1970’s. The aim of this study is to assess the gene flow patterns in Burkina Faso goat and to ascertain the most likely factors influencing geographic patterns of genetic variation in the Burkina Faso goat population. Results A total of 520 goat were sampled in 23 different locations of Burkina Faso and genotyped for a set of 19 microsatellites. Data deposited in the Dryad repository: http://dx.doi.org/10.5061/dryad.41h46j37. Although overall differentiation is poor (FST = 0.067 ± 0.003, the goat population of Burkina Faso is far from being homogeneous. Barrier analysis pointed out the existence of: a genetic discontinuities in the Central and Southeast Burkina Faso; and b genetic differences within the goat sampled in the Sahel or the Sudan areas of Burkina Faso. Principal component analysis and admixture proportion scores were computed for each population sampled and used to construct interpolation maps. Furthermore, Population Graph analysis revealed that the Sahel and the Sudan environmental areas of Burkina Faso were connected through a significant number of extended edges, which would be consistent with the hypothesis of long-distance dispersal. Genetic variation of Burkina Faso goat followed a geographic-related pattern. This pattern of variation is likely to be related to the presence of vectors of African animal trypanosomosis. Partial Mantel test identified the present Northern limit of trypanosome vectors as the most significant landscape boundary influencing the genetic variability of Burkina Faso goat (p = 0.008. The contribution of Sahel goat genes to the goat populations in the Northern and Eastern parts of the Sudan-Sahel area of Burkina Faso was substantial. The presence of perennial streams explains the existence of trypanosome vectors. The South
The NGO Terre Verte pursues the realisation of bocage perimeters (wégoubri in the mooré language) in Burkina Faso. They are an innovative concept of rural development that has been established in the 1990s in the experimental farm of Guiè and is now adopted in other experimental farms in Burkina Faso. The deterioration of the rural landscape in the Sahel region has worsened in the last decades, endangering local populations. The creation of bocage perimeters in this rural landscape is a way ...

Poverty at the national and sub-national level is commonly mapped on the basis of household surveys. Typical poverty metrics like the head count index are not able to identify its underlaying factors, particularly in rural economies based on subsistence agriculture. This paper relates agro-ecological marginality identified from regional and global datasets including remote sensing products like the normalized difference vegetation index (NDVI) and rainfall to rural agricultural production and food consumption in Burkina Faso. The objective is to analyze poverty patterns and to generate a fine resolution poverty map at the national scale. We compose a new indicator from a range of welfare indicators quantified from Georeferenced household surveys, indicating a spatially varying set of welfare and poverty states of rural communities. Next, a local spatial regression is used to relate each welfare and poverty state to the agro-ecological marginality. Our results show strong spatial dependency of welfare and poverty states over agro-ecological marginality in heterogeneous regions, indicating that environmental factors affect living conditions in rural communities. The agro-ecological stress and related marginality vary locally between rural communities within each region. About 58% variance in the welfare indicator is explained by the factors of rural agricultural production and 42% is explained by the factor of food consumption. We found that the spatially explicit approach based on multi-temporal remote sensing products effectively summarizes information on poverty and facilitates further interpretation of the newly developed welfare indicator. The proposed method was validated with poverty incidence obtained from national surveys.

In this study, the authors investigate farmers’ vulnerability to climate variability and evaluate local adoption of technology and farmers’ perceptions of adaptation strategies to rainfall variability and policies. A survey was conducted in a community in northern Burkina Faso following the crop failure of 2004. In 2006, following a better harvest, another survey was conducted to compare farmers’ actions and reactions during two contrasted rainy seasons. The results confirm that farmers from this community have substantially changed their practices during the last few decades. They have adopted a wide range of techniques that are intended to simultaneously increase crop yield and reduce yield variability. Micro water harvesting (Zaï) techniques have been widely adopted (41%), and a majority of fields have been improved with stone lines (60%). Hay (48%) and sorghum residues are increasingly stored to feed animals during the dry season, making bull and sheep fattening now a common practice. Dry season vegetable production also involves a majority of the population (60%). According to farmers, most of the new techniques have been adopted because of growing land scarcity and new market opportunities, rather than because of climate variability. Population pressure has reached a critical threshold, while land scarcity, declining soil fertility and reduced animal mobility have pushed farmers to intensify agricultural production. These techniques reduce farmers’ dependency on rainfall but are still insufficient to reduce poverty and vulnerability. Thirty-nine percent of the population remains vulnerable after a good rainy season. Despite farmers’ desire to remain in their own communities, migrations are likely to remain a major source of regular income and form of recourse in the event of droughts.

The policy of institutional delivery has been the cornerstone of actions aimed at monitoring and achieving MDG 5. Efforts to increase institutional births have been implemented worldwide within different cultural and health systems settings. This paper explores how communities in rural Burkina Faso perceive the promotion and delivery of facility pregnancy and birth care, and how this promotion influences health-seeking behaviour. A qualitative study was conducted in South-Western Burkina Faso between September 2011 and January 2012. A total of 21 in-depth interviews and 8 focus group discussions with women who had given birth recently and community members were conducted. The data were analyzed using qualitative content analysis and interpreted through Merton’s concept of unintended consequences of purposive social action. The study found that community members experienced a strong pressure to give birth in a health facility and perceived health workers to define institutional birth as the only acceptable option. Women and their families experienced verbal, economic and administrative sanctions if they did not attend services and adhered to health worker recommendations, and reported that they felt incapable of questioning health workers’ knowledge and practices. Women who for social and economic reasons had limited access to health facilities found that the sanctions came with increased cost for health services, led to social stigma and acted as additional barriers to seek skilled care at birth. The study demonstrates how the global and national policy of skilled pregnancy and birth care can occur in unintentional ways in local settings. The promotion of institutional care during pregnancy and at birth in the study area compromised health system trust and equal access to care. The pressure to use facility care and the sanctions experienced by women not complying may further marginalize women with poor access to facility care and contribute to worsened health

Studies on host factors, particularly the APOBEC3G gene, have previously found an association with AIDS progression in some populations and against some HIV-1 strains but not others. Our study had two main objectives: firstly, to screen a population from Burkina Faso for three variants of APOBEC3G previously described, and secondly to analyze the effect of these three variants and their haplotypes on HIV-1 infection with Circulating Recombinant Forms (CRFs) present in Burkina Faso. This case control study involved 708 seropositive and seronegative individuals. Genotyping was done by the TaqMan allelic discrimination method. Minor allele frequencies of rs6001417 (pratio analysis of genotypes and alleles of the different APOBEC3G variants showed that there is a strong association between the minor genetic variants, genotype of the three SNPs, and HIV-1 status. Haplotype analysis demonstrated that rs6001417, rs8177832, and rs35228531 are in linkage disequilibrium. The haplotype GGT from the rs6001417, rs8177832 and rs35228531 respectively has a protective effect OR = 0.54 [0.43-0.68] with P<0.001. There was also associations between the haplotypes GGC OR = 1.6 [1.1;-2.3] P<0.05, and CGC OR = 5.21 [2.4-11.3] P<0.001, which increase the risk of infection by HIV-1 from almost two (2) to five (5) fold. This study demonstrates an association of rs6001417, rs8177832, and rs35228531 of APOBEC3G with HIV-1 infection in a population from Burkina Faso. PMID:26741797

Full Text Available Malaria control programs are being jeopardized by the spread of insecticide resistance in mosquito vector populations. The situation in Burkina Faso is emblematic with Anopheles gambiae populations showing high levels of resistance to most available compounds. Although the frequency of insecticide target-site mutations including knockdown resistance (kdr and insensitive acetylcholinesterase (Ace-1(R alleles has been regularly monitored in the area, it is not known whether detoxifying enzymes contribute to the diversity of resistance phenotypes observed in the field. Here, we propose an update on the phenotypic diversity of insecticide resistance in An. gambiae populations sampled from 10 sites in Burkina Faso in 2010. Susceptibility to deltamethrin, permethrin, DDT, bendiocarb and fenithrotion was assessed. Test specimens (N = 30 per locality were identified to species and molecular form and their genotype at the kdr and Ace-1 loci was determined. Detoxifying enzymes activities including non-specific esterases (NSEs, oxydases (cytochrome P450 and Glutathione S-Transferases (GSTs were measured on single mosquitoes (N = 50 from each test locality and compared with the An. gambiae Kisumu susceptible reference strain. In all sites, mosquitoes demonstrated multiple resistance phenotypes, showing reduced mortality to several insecticidal compounds at the same time, although with considerable site-to-site variation. Both the kdr 1014L and Ace-1(R 119S resistant alleles were detected in the M and the S forms of An. gambiae, and were found together in specimens of the S form. Variation in detoxifying enzyme activities was observed within and between vector populations. Elevated levels of NSEs and GSTs were widespread, suggesting multiple resistance mechanisms segregate within An. gambiae populations from this country. By documenting the extent and diversity of insecticide resistance phenotypes and the putative combination of their underlying
Full Text Available Understanding land cover degradation patterns and the effects of geomorphological units on phytodiversity is important for guiding management decisions and restoration strategies in the Sahelian vulnerables zones. This paper describes land cover degradation by combining Landsat TM image analysis and field data measurements in the Gourouol catchment of the Sahelian zone of Burkina Faso. Erdas Imagine 9.2 and Arc-GIS.10 were applied. The change patterns were obtained by superposing land cover maps for 1992 and 2010. The field data were collected by the mean of inventories according to the Braun-Blanquet phytosociological relevés methods. Plot sizes were 50 m x 20 m for woody species and 10 m x 10 m for herbaceous species. Six land cover types were identified and mapped: cultivated lands, bared lands, lowlands, which all spatially increased; and shrub-steppes, grasslands and water bodies, which all spatially decreased. The dynamic patterns based on the geomorphological units were non-degraded lowlands, stable sand dunes and degraded glacis. High plant diversity was found in lowlands, whereas low diversity occurred in glacis. A significant dissimilarity was observed between communities. The Shannon diversity indices in plant communities were approximately close to ln(species richness. The Pielou indices were close to 1, indicating a species fairly good distribution. Our results showed a variation of land cover over time and the effects of geomorphological units on phytodiversity. Furthermore, this variation helps oppose land degradation in the Sahel.
Full Text Available This commentary traces recent regime change and political transition in Burkina Faso. After mass demonstrations Blaise Compaoré was forced to resign his presidency on 31 October 2014. His resignation was preceded by his attempt to change the constitution to allow him to stand for a fifth consecutive term in office. It is argued in this briefing that the way Compaoré’s rule ended should have come as no surprise because it was typical of both Burkina Faso’s political history since decolonisation and also the army’s historical role in the country’s presidential turnover. It was also typical of the current wave of mass protest struggles taking place in other African countries.

Since 2007, Burkina Faso has subsidized 80% of the costs of child birth. Women are required to pay 20% (900 F CFA = 1.4 Euros), except for the indigent, who are supposed to be exempted. The objective of the policy is to increase service utilization and reduce costs for households. We analyze the efficacy of the policy and the distribution of its benefits. The study was carried out in Ouargaye district. The analysis was based on two distinct cross-sectional household surveys, conducted before ...
Assessment of available water is the basis that allows for sustainable management of the water resource. Special need concerns the assessment of groundwater resources, about which, often little is known. The present study aims to explore the water resource, with a focus on groundwater, of a small catchment (3.5km2), situated in a semi-arid zone in Burkina Faso (West Africa). A 5-year data set of stable isotopes of water, groundwater level and other hydrologic data is used to gain insight into...
The world’s population is increasing by about 85 million every year (LEISINGER, 2000; WORLD BANK, 2000). These figures are closely related to the rapid growth of urban centers. Sub-Saharan Africa is one of the regions most affected by urbanization. It has an annual growth rate of 2.8% in the total population and 5.8% in the urban population (WORLD BANK, 2000). This process can also be seen in Burkina Faso, where the capital, Ouagadougou, had a growth rate of 6.8% in 1998 com...
Full Text Available Abstract Background and methods A longitudinal Anopheles gambiae s.l. insecticide-resistance monitoring programme was established in four sentinel sites in Burkina Faso. For three years, between 2008 and 2010, WHO diagnostic dose assays were used to measure the prevalence of resistance to all the major classes of insecticides at the beginning and end of the malaria transmission season. Species identification and genotyping for target site mutations was also performed and the sporozoite rate in adults determined. Results At the onset of the study, resistance to DDT and pyrethroids was already prevalent in An. gambiae s.l. from the south-west of the country but mosquitoes from the two sites in central Burkina Faso were largely susceptible. Within three years, DDT and permethrin resistance was established in all four sites. Carbamate and organophosphate resistance remains relatively rare and largely confined to the south-western areas although a small number of bendiocarb survivors were found in all sites by the final round of monitoring. The ace-1R target site resistance allele was present in all localities and its frequency exceeded 20% in 2010 in two of the sites. The frequency of the 1014F kdr mutation increased throughout the three years and by 2010, the frequency of 1014F in all sites combined was 0.02 in Anopheles arabiensis, 0.56 in An. gambiae M form and 0.96 in An. gambiae S form. This frequency did not differ significantly between the sites. The 1014S kdr allele was only found in An. arabiensis but its frequency increased significantly throughout the study (P = 0.0003 and in 2010 the 1014S allele frequency was 0.08 in An. arabiensis. Maximum sporozoite rates (12% were observed in Soumousso in 2009 and the difference between sites is significant for each year. Conclusion Pyrethroid and DDT resistance is now established in An. gambiae s.l. throughout Burkina Faso. Results from diagnostic dose assays are highly variable within and
The vast majority of land users at the Central Plateau of Burkina Faso make a living by farming small plots, where mainly staple crops are produced for subsistence use.

: Global advocacy campaigns increasingly highlight the negative impact of reproductive morbidity on economic productivity and development in order to justify donor investment in maternal health. Anthropological approaches nuance such narrow economic estimations of reproductive health. Drawing on ethnographic fieldwork from Burkina Faso in West Africa, this paper analyses the dynamic, and sometimes contradictory, relationship between women's work and reproductive health in impoverished communi...

Despite health reform and increasing public investment in the health sector, utilization of curative health services, immunization coverage and patient satisfaction with the public health care system are steadily decreasing in Burkina Faso. It seems that the health care system itself is "ill". This paper examines the major symptoms associated with this illness. The central thesis suggests that any further improvement of health care performance in Burkina Faso will be subject to profound central reform in the area of human resources and financial management of the sector. Such a broad reform package cannot be achieved through the current project approach, but a sector-wide approach (SWAp) does not seem to be realistic at the present time. Policy discussions at a level higher than the Ministry of Health could be beneficial for achieving better donor coordination and increasing the commitment of the Ministry of Health to a sector-wide approach. Health sector reform issues and priorities and the role of international cooperation are reviewed and discussed. PMID:11238434

Many studies, using information integration theory, have been devoted to the prediction of performance on the basis of ability and motivation information. However, it appears that only two societies. American and East Indian, have been examined with regard to their prevalent performance prediction model. Participants in this study were school children in Burkina Faso, West Africa. Considerable differences between individuals were expected because, as a consequence of colonization, Burkina Faso has been torn between two different value systems: a collectivistic system, with traditional tribal Burkinabè values, and an individualistic system, with occidental values. The study's most notable finding was the coexistence of these two value systems within the same society. The predominant logic of Western societies, that increased motivation will result in increased rewards when initial ability is high, was utilized by 42% of the children; in contrast, 38% of the children applied the dominant logic expressed by East Indian researchers, who have found that regardless of the level of ability, any amount of motivation will result in an identical improvement in performance.

Objective:To evaluate the prevalence of toxoplasmosis and rubella among pregnant women at Ouagadougou in Burkina Faso. Methods: All patient sera were tested for rubella and toxoplasmosis anti-IgG using commercial ELISA kits (PlateliaTM Rubella IgG and Platelia™Toxo IgG). The presence of anti-rubella and anti-toxoplasmosis IgM in serum samples was tested using commercial ELISA kits Platelia Rubella IgM and Platelia Toxo IgM. Results:Among all the pregnant women tested for toxoplasmosis and rubella, their prevalence were 20.3%and 77.0%, respectively. Pregnant women in the age group of 18-25 years showed the highest frequency of anti-toxoplasmosis (34.5%) and anti-rubella IgG (84.6%). The prevalence of anti-toxoplasma and anti-rubella IgG decreased between 2006 and 2008 from 32.7%to 12.1%and 84.6%to 65.0%, respectively. There was no significant association between age and the mean titer of anti-toxoplasmosis IgG among pregnant women. Conclusions: The diagnosis of toxoplasmosis and rubella is necessary in pregnant women in Burkina Faso because of the low immunization coverage rate of rubella and the high level of exposure to these two infections which can be harmful to the newborn if contracted by women before the third trimester of pregnancy.

Sorghum malt and dolo quality evaluation criteria and parameters affecting quality were surveyed in six cities in Burkina Faso through questionnaires addressed to malt processors, dolo processors, retailers, and consumers. The major quality criteria for malt quality assessment were perceived to be taste and presence/absence of roots in the malt. Taste, alcohol content, and wort sufficiently cooked were perceived as major criteria for the dolo quality assessment. The major parameters affecting malt quality were perceived to be malt production period, proportions of grain and the amount of water entering malting, presence of pesticide residues in the malting grains, and age of grain. Processing method, yeast source, proportions of the components (crushed grain, water, mucilage, yeast) entering dolo production, malt quality, wort temperature at time of inoculation, amount of energy available for cooking, wort and sediment boiling time, quality of mucilage, malt with non-sweet taste, presence/absence of roots in the malt, and ease of filtering crushed malt were perceived as major parameters affecting the dolo quality. These results will be used in the improvement of the dolo supply chain in Burkina Faso by providing more reliable information for training programs for efficient dolo brewing processes, development of best cropping practices to improve grain quality, and providing better selection criteria for sorghum breeding programs.

In the central region of the Burkina Faso, small holders like to use veterinary traditional practice to treat small ruminant gastro-intestinal parasitism. In this part of country, Daniellia oliveri plant is usually used against this disease. Aqueous decoction obtained from the stem barc of Daniellia oliveri was screened to determine his phytochemical composition and in vitro anthelminthic activity agains Haemonchus contortus adult worms. Results showed that the decoction lyophilized obtained is giving to small ruminant (25 kg) at the rate of 242.5 mg per body weight. In vitro anthelminthic revealed that Daniellia oliveri extract has significant effect (P < 0.05) on mortality or the paralysis of the adult worms of Haemonchus contortus compared to the control group. In fact, use of Daniellia oliveri leaves by pastoralist smallholders in traditional therapy against the gastro-intestinal small ruminant parasites is justified in the central region of the Burkina Faso. Therefore, the survey suggests to achieve other studies (phytochemical and toxicity) on Anogeissus leiocarpus leaves studied in order to develop a further drug antiparasitic subsequently
Traditional Veterinary practice is current by pastoralist and small holders to treat small ruminant gastro-intestinal parasitism in the central region of the Burkina Faso. To treat these digestive pathologies, Anogeissus leiocarpus is usually used. Ethno-veterinary surveys have been achieved to understand the traditional use of Anogeissus leiocarpus and in vitro test has been carried out to value anthelminthic activity on the adult worms of Haemonchus contortus. Results showed that the plant part used are leaves and by oral way after decoction to obtain aqueous extract which is giving to small ruminant (25 kg) at the rate of 160 mg per body weight. In vitro anthelminthic activity test of aqueous extract of leaves revealed a significant effect (P < 0,05) on mortality or the paralysis of the adult worms of Haemonchus contortus compared to the control group (PBS). In fact, use of Anogeissus leiocarpus leaves by pastoralist and small holders in traditional therapy against the gastro-intestinal small ruminant parasites is justified in the central region of the Burkina Faso. Therefore, the survey suggests to achieve other pharmacologies and parasitologies studies on Anogeissus leiocarpus leaves in order to develop a further drug antiparasitic subsequently
The introduction of biogas to Burkina Faso was done in 1976 through program of research and development. Agricultural and Animal waste is the principal substrates and the produced gas is useful principally to satisfy the domestic energy needs. The technological outputs go from 200 has 300 liters per m3 of tank whereas the biological outputs are of 100 has 300 liters per kilogram of dry matter. The cost of the installations vary from 12000 to 100000 Fcfa per m3 of tank according to the type of digester. In August 1998, only the installation of biogas of the School of Water and Drill of Dinderesso (Bobo-Dioulasso) produced biogas. According to the estimates, Burkina Faso respectively has an annual average potential of production theoretical and accessible about 4694 million and 2790 million m3 of biogas coming by order from importance from livestock wastes, farming, human and urban. By taking a coefficient of 60% to take account of the imperfections of technology and implementation, 1674 million m3 of biogas (accessible) could have been produced from the biomass over the period 1990-1996. For the same period, this quantity of biogas could have generated annually 2000 to 2344 GWh of electricity (cogeneration) against 218 GWh for the SONABEL

Burkina Faso is part of the Sahel-Sudan climatic zone south of the Sahara Desert. The rainfall of the region is characterized by extreme seasonal and annual temporal and spatial variability. Soils are generally of low fertility. The major livelihood activity in Burkina Faso, one of the lowest ranked countries in the world in the Human Development Index where 80 percent of the population rely on subsistence farming, is rainfed cultivation of cereal crops. Cotton is the dominant export crop and is mostly grown in the southwest. Livestock management is an important complement to farm activities, especially in the Sahelian zone. There are several major rivers flowing through the region and many ephemeral streams. Surface water resources are becoming more important to Burkina Faso as it tries to improve food security and water supplies, and increase energy production. One of the major opportunities to improve livelihoods in the region has been improvements in seasonal rainfall forecasting based upon global sea surface temperatures. In the past decade, the generation and use of forecasts in Burkina Faso has evolved from the nation just receiving forecasts almost as an after thought from USA and European meteorological services to the Burkina Faso Meteorological Services generating their own forecasts with support from these services. There is now also more focused international research on improving the forecasts for this region. The use of stochastic decision support tools (DST) that combine the seasonal forecasts with hydrologic and crop models, land conditions, and information on farmer and policy maker goals could improve both rainfed and irrigated agricultural systems. Their implementation requires overcoming many technical and socio-economic challenges. Examples include forecasting the start and end of rains, dissemination and explanation of forecasts, streamflow forecasting in data scarce regions, possible different incentives for subsistence and cash crop farmers

Full Text Available Abstract Background Agricultural biotechnology public-private partnerships (PPPs have been recognized as having great potential in improving agricultural productivity and increasing food production in sub-Saharan Africa. However, there is much public skepticism about the use of GM (genetically modified crops and suspicion about private sector involvement in agbiotech projects. This case study sought to understand the role of trust in the Bacillus thuringiensis (Bt cotton in Burkina Faso project by exploring practices and challenges associated with trust-building, and determining what makes these practices effective from the perspective of multiple stakeholders. Methods We conducted semi-structured, face-to-face interviews to obtain stakeholders’ understanding of trust in general as well as in the context of agbiotech PPPs. Relevant documents and articles were analyzed to generate descriptions of how trust was operationalized in this evolving agbiotech PPP. Data was analyzed based on emergent themes to create a comprehensive narrative on how trust is understood and built among the partners and with the community. Results We derived four key lessons from our findings. First, strong collaboration between research, industry and farmers greatly contributes to both the success of, and fostering of trust in, the partnership. Second, this case study also revealed the important, though often unrecognized, role of researchers as players in the communication strategy of the project. Third, effective and comprehensive communication takes into account issues such as illiteracy and diversity. Fourth, follow-up at the field level and the need for a multifaceted communications strategy is important for helping push the project forward. Conclusions Burkina Faso’s well-established and effective cotton selling system laid the foundation for the implementation of the Bt cotton project – particularly, the strong dialogue and the receptivity to collaboration

Full Text Available Lineage organization, motor of the cotton farming growth? The Bwa of Burkina Faso. In Burkina Faso, country producing cotton, the social situations, the results and performances of the cotton farmers are various. The present research focus on the cotton area of Houndé in the Bwaba region. It is one of the most productive areas of the country where the growth of cotton has been a success story. The reasons for this success are analysed in the village called Dossi, focusing on the links between the cotton growth and the social organization, particularly the lineage one. The national cotton production is based on the Cotton Groups Farmers. Dossi's analysis shows that two kinds of relationships organize Cotton Groups Farmers: relationships between founding lineages and hosted families on one hand, relationships between elders and subjected members of the lineages on the other hand. The traditional lineage organization, adapting and rationalizing cotton production's management, became one of the key to cotton's success, in the area of Houndé. The cotton business could grow because it did not challenge the traditionnal organization. Nevertheless, economic and social inequalities increased with the development of cotton production in the villages. Today, belonging to a founding lineage is decisive in the cotton production context. However, social transformations are in progress inside founding lineages. Indeed some cadets manage big farms whereas it would have been impossible fifty years ago. Farm advice should be given according to the lineage position of each farmer. It would guarantee for all farmers the improvement of their social and economic condition. Today, it is necessary to strengthen rural cotton farming communities because they are weakened by the privatization of a part of cotton industry in Burkina Faso.
Full Text Available Abstract Background To bring down its high maternal mortality ratio, Burkina Faso adopted a national health policy in 2007 that designed to boost the assisted delivery rate and improving quality of emergency obstetrical and neonatal care. The cost of transportation from health centres to district hospitals is paid by the policy. The worst-off are exempted from all fees. Methods The objectives of this paper are to analyze perceptions of this policy by health workers, assess how this health policy was implemented at the district level, identify difficulties faced during implementation, and highlight interactional factors that have an influence on the implementation process. A multiple site case study was conducted at 6 health centres in the district of Djibo in Burkina Faso. The following sources of data were used: 1 district documents (n = 23; 2 key interviews with district health managers (n = 10, health workers (n = 16, traditional birth attendants (n = 7, and community management committees (n = 11; 3 non-participant observations in health centres; 4 focus groups in communities (n = 62; 5 a feedback session on the findings with 20 health staff members. Results All the activities were implemented as planned except for completely subsidizing the worst-off, and some activities such as surveys for patients and the quality assurance service team aiming to improve quality of care. District health managers and health workers perceived difficulties in implementing this policy because of the lack of clarity on some topics in the guidelines. Entering the data into an electronic database and the long delay in reimbursing transportation costs were the principal challenges perceived by implementers. Interactional factors such as relations between providers and patients and between health workers and communities were raised. These factors have an influence on the implementation process. Strained relations between the groups involved
Full Text Available A raw clay material from Burkina Faso has been characterized for pozzolan elaboration. The analysis showed that SiO2 (45.91 wt. %, Al2O3 (28.29 wt. % and Fe2O3 (9.75 wt. % are the main oxides and kaolinite (71 wt. % is the principle mineral. The sample has been activated at 680 °C during 2 or 5 hours. The pozzolanic activity has been accessed by coupling several methods. The chemical methods showed the good lime fixing ability by the activated sample. At the first 24 hours, more than 50 wt. % of the lime is fixed and at 28 days around 90 wt. % of lime are fixed. Mineralogical analyses showed the disappearing of portlandite (CH and the formation of new C-S-H hydrates. The pozzolanic index (81 % calculated from mechanical strength of mortars made with 25 wt. % substitution of cement by the pozzolan confirm it suitability for portland cement replacement in the field of building materials.

Full Text Available The various kinds of information released in the press and other media are cultural products that partake in the shaping of citizens' opinions and minds. Radio and television in particular present their audiences in Burkina Faso with various life-styles through diverse entertainment programmes which have grown popular among the urban population. These are fertile fields for cultural imperialism in the country. In the on-going process of internationalization of culture facilitated by the new communication technology, the cultural identity of Africans is increasingly threatened. This phenomenon is the result of adverse political and economic conditions with significant cultural consequences. In the long run, these cultural consequences will lead to the marginalization of Africa on the international scene and its increased dependence on the western powers.

Full Text Available The influence of MgO on mechanical and microstructural properties of raw clay material from Burkina Faso was investigated by means of X-ray diffraction, scanning electron microscopy, infrared spectroscopy, differential thermal analysis and numerical simulation. The mineralogical composition was modified with the formation of new crystalline phases such as mullite, spinel – Mg, enstatite and forsterite. During the sintering and with add of MgO, the mullite quantity decrease contrary to forsterite and affect the different properties of sintered products. The mechanical properties were improved with MgO amount around 2 – 5 wt%. For magnesia amount higher than 5 wt%, the magnesia is not entirely consumed and is originated to the formation of pores in the manufactured products which are detrimental to the mechanical properties.
Control operations against tsetse flies with the sterile insect technique (SIT) were conducted by the Centre de recherches sur les trypanosomoses animales (CRTA) (Institut d'elevage et de medecine veterinaire des pays tropicaux/Gesellschaft fuer Technische Zusammenarbeit (IEMVT/GTZ) Project), Bobo-Dioulasso (Burkina Faso). The project ended in 1984 with the eradication in the Sideradougou pastoral zone of the three tsetse species present there (Glossina palpalis gambiensis, G. tachinoides and G. morsitans submorsitans). Since 1985, besides monitoring of this area, the CRTA oriented its activities towards improving trapping by carrying out research on the form and colour of targets as well as the use of olfactory attractants.

In the Sourou area of Burkina Faso, parasitological and malacological surveys of urinary schistosomiasis have been carried out in the constructed sites of Guédougou, Niasan and Débé dating respectively from 1967, 1986 and 1996. The investigations covered also the traditional villages of Lanfiera, Di, Poro, Tiao and Mara situated in the middle of the hydroagricultural planning for the first, very close to the lake for the second and about twenty kilometres distant for the three last. These towns represent the main sites in the Sourou area. The results of the parasitological surveys showed that urinary schistosomiasis was present in all sites. The levels of prevalence varied considerably: 70.3% in Guiédougou, 40.8% in Niassan, 8.5% in Débè in the irrigated zone, 55.6% in Lanfiéra, 56.8% in Di, 13.2% in Poro, 83.3% in Tiao and 64.7% in Mara. Concerning the malacological investigation, two species (Bulinus senegalensis and B. truncatus) were shown to be intermediate hosts of Schistosoma haematobium. The first was endemic to the area while the second was compatible with S. haematobium from the Sourou and other zones. Compared to the results of earlier investigations, the endemic had worsened with differences according to sites. This disparity of prevalence levels which has already been observed in other hydroagricultural area results from many factors, among which the impact of irrigation activities, the aquatic biotope system (irrigation canals, natural lake, pools and temporary rivers) and the type of contact of human communities with water rank high. Schistosomiasis expansion is amplified by the intermediate host dynamics and the introduction of new schistosomes carried by the new workers arriving from all over the country. In these conditions, in order to reduce rapidly prevalence levels, preventive measures should be centred on chemotherapy for the population. The treatment should be administered during a period of weak intermediate host density and be

Enteric viruses are a major cause of diarrhea in children, especially those under five years old. Identifying the viral agents is critical to the development of effective preventive measures. This study aimed to determine the prevalence and genetic diversity of common enteric viruses in children under five years old in Burkina Faso. Stool samples from children with (n = 263) and without (n = 50) diarrhea disorders were collected in Ouagadougou, Burkina Faso from November 2011 to September 2012. Rotavirus, norovirus, sapovirus, astrovirus, adenovirus and Aichivirus A were detected using real-time or end-point (RT-)PCR. Rotavirus strains were G and P genotyped by multiplex RT-PCR and other viral strains were characterized by sequencing of viral subgenomic segements. At least one viral agent was detected in 85.6% and 72% of the symptomatic and asymptomatic patients, respectively. Rotavirus (63.5%), adenovirus (31.2%) and genogroup II norovirus (18.2%) were the most prevalent viruses in symptomatic patients, but only rotavirus and genogroup II norovirus were significantly associated with diarrhea (OR: 7.9, 95%CI: 3.7-17; OR: 3.5, 95%CI: 1-11.7, respectively). Sapovirus (10.3%), astrovirus (4.9%), genogroup I norovirus (2.7%) and Aichivirus A (0.8%) were less prevalent. The predominant genotype of rotavirus was G9P (36.5%), and the predominant norovirus strain was GII.4 variant 2012 (71.4%). Among sapovirus, the genogroup II (87.5%) predominated. Astrovirus type 1 (41.7%) was the most frequent astrovirus identified. Aichivirus A belonged to the three genotypes (A, B and C). Enteric adenoviruses type 40 and 41 were identified in 10.2% and 5.1% respectively. Several cases of co-infections were detected. The results highlight the high prevalence and the high diversity of enteric viruses in Burkinabe children. PMID:27092779

The predominant genotype of rotavirus was G9P (36.5%, and the predominant norovirus strain was GII.4 variant 2012 (71.4%. Among sapovirus, the genogroup II (87.5% predominated. Astrovirus type 1 (41.7% was the most frequent astrovirus identified. Aichivirus A belonged to the three genotypes (A, B and C. Enteric adenoviruses type 40 and 41 were identified in 10.2% and 5.1% respectively. Several cases of co-infections were detected. The results highlight the high prevalence and the high diversity of enteric viruses in Burkinabe children.

Riparian forests are classified as endangered ecosystems in general, particularly in sahelian countries like Burkina Faso because of human-induced alterations and civil engineering works. The modification of this important habitat is continuing, with little attention being paid to the ecological or human consequences of these changes. The objective of this study is to describe the variation of woody species diversity and dynamic in riparian forests on different type of watercourse banks along phytogeographical gradient in Burkina Faso. All woody species were systematically measured in 90 sample plots with sides of 50 m × 20 m.Density, dominance, frequency and species and family importance values were computed to characterize the species composition. Different diversity indices were calculated to examine the heterogeneity of riparian forests. A total of 196 species representing 139 genera and 51 families were recorded in the overall riparian forests. The species richness of individuals with dbh ≥ 5cm increased significantly from the North to the South along the phytogeographical gradient and varied significantly between the different types of riparian forests. Similarity in tree species composition between riparian forests was low, which indicates high beta diversity and reflects differences in habitat conditions and topography.The structural characteristics varied significantly along the phytogeographical gradient and between the different types of riparian forests.The diameter class distribution of trees in all riparian forests showed a reverse “J” shaped curve except riparian forest of stream indicating vegetation dominated by juvenile individuals. Considering the ecological importance of riparian forest, there is a need to delineate and classify them along watercourses throughout the country.
Full Text Available Since 2007, Burkina Faso has subsidized 80% of the costs of child birth. Women are required to pay 20% (900 F CFA = 1.4 Euros, except for the indigent, who are supposed to be exempted. The objective of the policy is to increase service utilization and reduce costs for households. We analyze the efficacy of the policy and the distribution of its benefits.The study was carried out in Ouargaye district. The analysis was based on two distinct cross-sectional household surveys, conducted before (2006; n= 1170 and after (2010; n = 905 the policy, of all women who had had a vaginal delivery in a public health centre.Medical expenses for delivery decreased from a median of 4,060 F CFA in 2006 to 900 F CFA in 2010 (p<0.001. There was pronounced contraction in the distribution of expenses and a reduction in interquartile range. Total expenses for delivery went from a median of 7,366 F CFA in 2006 to 4,750 F CFA in 2010 (p = 0.001. There was no exacerbation of the initial inequalities of the share in consumption after the policy. The distribution of benefits for medical expenses showed a progressive evolution. The greatest reduction in risk of excessive expenses was seen in women in the bottom quintile living less than 5 km from the health centres. Only 10% of those in the poorest quintile were exempted. The subsidy policy was more effective in Burkina Faso than in other African countries. All categories of the population benefited from this policy, including the poorest. Yet despite the subsidy, women still carry a significant cost burden; half of them pay more than they should, and few indigents are fully exempted. Efforts must still be made to reach the indigent and to reduce geographic barriers for all women.
Background Providing health care services in Africa is hampered by severe scarcity of personnel, medical supplies and financial funds. Consequently, managers of health care institutions are called to measure and improve the efficiency of their facilities in order to provide the best possible services with their resources. However, very little is known about the efficiency of health care facilities in Africa and instruments of performance measurement are hardly applied in this context. Objective This study determines the relative efficiency of primary care facilities in Nouna, a rural health district in Burkina Faso. Furthermore, it analyses the factors influencing the efficiency of these institutions. Methodology We apply a two-stage Data Envelopment Analysis (DEA) based on data from a comprehensive provider and household information system. In the first stage, the relative efficiency of each institution is calculated by a traditional DEA model. In the second stage, we identify the reasons for being inefficient by regression technique. Results The DEA projections suggest that inefficiency is mainly a result of poor utilization of health care facilities as they were either too big or the demand was too low. Regression results showed that distance is an important factor influencing the efficiency of a health care institution Conclusions Compared to the findings of existing one-stage DEA analyses of health facilities in Africa, the share of relatively efficient units is slightly higher. The difference might be explained by a rather homogenous structure of the primary care facilities in the Burkina Faso sample. The study also indicates that improving the accessibility of primary care facilities will have a major impact on the efficiency of these institutions. Thus, health decision-makers are called to overcome the demand-side barriers in accessing health care. PMID:22828358

Water scarcity constrains the livelihoods of millions of people in tropical drylands. Tree planting in these environments is generally discouraged due to the large water consumption by trees, but this view may neglect their potential positive impacts on water availability. The effect of trees on soil hydraulic properties linked to groundwater recharge is poorly understood. In this study, we performed 18 rainfall simulations and tracer experiments in an agroforestry parkland in Burkina Faso to...

In Burkina Faso, abortion is legally restricted and socially stigmatised, but also frequent. Unsafe abortions represent a significant public health challenge, contributing to the country's very high maternal mortality ratio. Inspired by an internationally disseminated public health framing of unsafe abortion, the country's main policy response has been to provide post-abortion care (PAC) to avert deaths from abortion complications. Drawing on ethnographic research, this article describes how ...

Although the 2008 food price crisis presumably plunged millions of households into poverty and food insecurity, the real impact of the crisis has rarely been documented using field data. Our objective was to assess the consequences of this crisis for household food insecurity and dietary diversity in urban Burkina Faso. Two cross-sectional surveys were conducted among randomly selected households in Ouagadougou in July 2007 (n = 3017) and July 2008 (n = 3002). At each round, food insecurity a...

The water distilled oil obtained from rhizomes of Cochlospermum planchonii Hook.f.ex Planch (Apocynaceae) from Burkina Faso was examined by GC and GC/MS. Cochlospermum planchonii oil presents a particular chemical composition with a high rate of oxygenated components with predominance of ketones and esters (86.4%). The essential oil was tested against twelve strains of bacteria using a broth microdilution method. The results suggest that Cochlospermum planchonii essential oil has significant bactericidal activity. PMID:19090305

Price instability is a major concern for commodity producers in developing countries. Commodity derivative markets have become the central pricing mechanism for international commodity trade. This is problematic given the high volatility and increased short-termism of these markets in the context of financialisation. The effects on producers depend on the market structure in producer countries. Burkina Faso and Mozambique have different types of national cotton price stabilization schemes in ...
Full Text Available Cette étude évalue l’impact des changements climatiques sur les revenus agricoles des agriculteurs au Burkina Faso, en utilisant l’approche ricardienne. Cette méthode permet de modéliser les revenus agricoles en fonction des variables climatiques, édaphiques, hydrologiques et socio-économiques. Plusieurs modèles économétriques ont été testés sur la base des données primaires de la campagne agricole 2002-2003. Ces modèles ont permis d’établir d’une part la relation qui existe entre le revenu agricole et les variables climatiques (température et précipitation et d’autre part, d’analyser la sensibilité des revenus agricoles par rapport à ces variables climatiques. Des simulations ont été faites sur la base des prévisions du groupe d’experts intergouvernemental sur l’évolution du climat (GIEC. Les résultats de l’étude ont montré que la relation entre le revenu et le climat est non linéaire. L’impact marginal de la température sur le revenu agricole est de -19,9 dollars US par hectare tandis que celui de la précipitation est de +2,7 dollars US par hectare. L’analyse des élasticités montre que l’agriculture est très sensible à la précipitation au Burkina. L’augmentation des précipitations de 1% entraine une hausse des revenus agricoles de 14,7%. Cependant, une augmentation des températures de 1% entraine une baisse des revenus agricoles de 3,6%. Les analyses de sensibilité ont montré que les paysans perdront 93% de leurs revenus suite à une augmentation de la température de 5°C. Ils perdront tout leur revenu suite à une diminution des précipitations de 14% (ceteris paribus. Du fait des conditions climatiques déjà difficiles, les scenarii de diminution des précipitations ou/et d’augmentation des températures sont très dommageables à l’agriculture au Burkina. Par ailleurs, l’étude a montré que la pratique de l’irrigation et l’accès à la vulgarisation ont un effet

Local knowledge could form an effective channel and base through which climate change adaptation and mitigation can be realized. This paper uses the context of savannas ecosystem services in Burkina Faso to examine local knowledge and perspectives on the changing trends in vulnerability and adaptation to climate change. The survey targeted farmers, traditional authorities and administrators at the local government level. Semi-structured questionnaires were employed for one-on-one interviews and focused group discussions for data collection. Descriptive statistics and explanatory factor analysis were used to analyze the collected data. A total of 230 farmers, 6 traditional authorities and 5 administrators belonging to 32 villages were interviewed. Most of local people (95.1-96.7%) believe that climate change is occurring, and cited general increases in average temperatures, fluctuating rainfall regimes and extended drought periods as some of their observations. They explain the increasing changes and vulnerability of savannas ecosystems through the longer time spent and distance covered to collect medicinal plants and forest food; decreasing productivity and availability of fodder, fuel wood, forest food and medicinal plant, changing uses of forest food and medicinal plant species. The views of farmers were generally shared by the traditional authorities and administrators. Adaptation actions employed by local communities are tree planting, protection of forestry resources, migration, awareness raising, conservation of soil and water resources.

Global advocacy campaigns increasingly highlight the negative impact of reproductive morbidity on economic productivity and development in order to justify donor investment in maternal health. Anthropological approaches nuance such narrow economic estimations of reproductive health. Drawing on ethnographic fieldwork from Burkina Faso in West Africa, this paper analyses the dynamic, and sometimes contradictory, relationship between women's work and reproductive health in impoverished communities. Specifically, it examines the consequences of life-threatening 'near-miss' obstetric complications for women's work across domestic, agricultural and economic spheres over a four-year period. Such events provide a window onto the diverse ways in which production and reproduction are intimately linked within women's everyday lives. Reproduction and production entail sources of potential empowerment and enhancement, as well as potential threats, to health and well-being. In the aftermath of 'near-miss' events, the realms of reproduction and production sometimes jeopardise each other and at other times reinforce each other, while strength in one domain can compensate for weakness in the other. Women's experiences thus reveal how 'production' and 'reproduction' are mutually constituted, challenging the purely instrumental accounts of pregnancy-related 'productivity loss' that dominate current global health discourse.

Full Text Available A Mobile Laboratory was developed for use primarily during the epidemic meningitis season in Burkina Faso. This report describes the Mobile Laboratory characteristics, its use to date, problems encountered and their resolution, and future directions. During 2004, the mobile laboratory intervention in three remote Burkina Faso districts experiencing meningitis epidemics led to more speciﬁc case management and led directly to vaccination of one district. However, in a second district, the intervention occurred too late to allow vaccination. During 2006, the Mobile Laboratory was used to conduct an emergency carriage study that for the ﬁrst time occurred during the peak of a meningococcal serogroup A epidemic. This information is critical for the design of meningococcal conjugate vaccine schedules and vaccine approaches. During 2004-6, technicians in 11 district laboratories received training by Mobile Laboratory staff. Numerous problems with the initial prototype laboratory were identiﬁed, namely that the solar power cells could not provide enough energy to the refrigerator and incubator to maintain appropriate temperatures and having a single integrated unit required use of a separate vehicle for specimen transport. A second laboratory was developed during 2005-6 that used a generator or local energy source for power and that had a laboratory that could be detached from the vehicle. Currently the main limitation of the Mobile Laboratory is that it has not been integrated into routine Ministry of Health activities, limiting its use both during and between meningitis seasons.Un Laboratoire Mobile a été développé pour être utilisé essentiellement pendant la saison d’épidémie de méningite au Burkina Faso. Ce rapport décrit les caractéristiques du Laboratoire Mobile, son utilisation à ce jour, les problèmes rencontrés et leur résolution ainsi que les orientations futures.

Full Text Available Abstract Background Drug-resistant tuberculosis (DR-TB is considered a real threat to the achievement of TB control. Testing of mycobacterial culture and testing of drug susceptibility (DST capacity are limited in resource-poor countries, therefore inadequate treatment may occur, favouring resistance development. We evaluated the molecular assay GenoType® MTBDRplus (Hain Lifescience, Germany in order to detect DR-TB directly in clinical specimens as a means of providing a more accurate management of chronic TB patients in Burkina Faso, a country with a high TB-HIV co-infection prevalence. Methods Samples were collected in Burkina Faso where culture and DST are not currently available, and where chronic cases are therefore classified and treated based on clinical evaluation and sputum-smear microscopy results. One hundred and eight chronic TB patients (sputum smear-positive, after completing a re-treatment regimen for pulmonary TB under directly observed therapy were enrolled in the study from December 2006 to October 2008. Two early morning sputum samples were collected from each patient, immediately frozen, and shipped to Italy in dry ice. Samples were decontaminated, processed for smear microscopy and DNA extraction. Culture was attempted on MGIT960 (Becton Dickinson, Cockeysville, USA and decontaminated specimens were analyzed for the presence of mutations conferring resistance to rifampin and isoniazid by the molecular assay GenoType® MTBDRplus. Results We obtained a valid molecular test result in 60/61 smear-positive and 47/47 smear-negative patients. Among 108 chronic TB cases we identified patients who (i harboured rifampin- and isoniazid-susceptible strains (n 24, (ii were negative for MTB complex DNA (n 24, and (iii had non-tuberculous mycobacteria infections (n 13. The most represented mutation conferring rifampin-resistance was the D516V substitution in the hotspot region of the rpoB gene (43.8% of cases. Other mutations recognized
The first cases of AIDS in Burkina Faso were reported in 1986. During the past ten years, there have been several types of research conducted in Burkina Faso in the field of social sciences, including KABP, focus groups, and ethnographic studies. This article reviews approximately 100 publications and presents the results most relevant to prevention. Although general knowledge of the disease, its transmission and means of protection has improved, part of the population remains poorly informed; erroneous ideas remain prevalent and certain concepts, for example asymptomatic infection, are ignored. Young women in rural areas have the poorest knowledge. Understanding the information is conditioned by underlying perceptions of blood and physiology, the "components of the person", pre-existent and sexually transmitted diseases, and modes of transmission. Research on sexuality has elucidated the age at which individuals become sexually active, and paramatrimonial practices. The prevalence of STD is high. STD are mostly treated by traditional practitioners or by automedication. Family planning is insufficiently developed. AIDS prevention should be integrated into wider considerations of reproductive health. The popular perception that "Others" are responsible for bringing AIDS into the country has often been reinforced by health messages. Consequently, people do not sufficiently consider themselves vulnerable to HIV infection. The populations that are most vulnerable, for various reasons that have been analysed, include young girls and women, married women, prostitutes, truck drivers, and young men from rural areas. The message "Fidelity or condom" has been widely used. However, it has hindered the generalisation of the use of condoms, because asking for a condom consequently implies distrust of the partner. The interpretation of fidelity is diverse, and many people who choose this means of prevention believe erroneously that they are protected. Studies of the social

Full Text Available Abstract Background Systems to exempt the indigent from user fees have been put in place to prevent the worst-off from being excluded from health care services for lack of funds. Yet the implementation of these mechanisms is as rare as the operational research on this topic. This article analyzes an action research project aimed at finding an appropriate solution to make health care accessible to the indigent in a rural district of Burkina Faso. Research This action research project was initiated in 2007 to study the feasibility and effectiveness of a community-based, participative and financially sustainable process for exempting the indigent from user fees. A interdisciplinary team of researchers from Burkina Faso and Canada was mobilized to document this action research project. Results and knowledge sharing The action process was very well received. Indigent selection was effective and strengthened local solidarity, but coverage was reduced by the lack of local financial resources. Furthermore, the indigent have many other needs that cannot be addressed by exemption from user fees. Several knowledge transfer strategies were implemented to share research findings with residents and with local and national decision-makers. Partnership achievements and difficulties Using a mixed and interdisciplinary research approach was critical to grasping the complexity of this community-based process. The adoption of the process and the partnership with local decision-makers were very effective. Therefore, at the instigation of an NGO, four other districts in Burkina Faso and Niger reproduced this experiment. However, national decision-makers showed no interest in this action and still seem unconcerned about finding solutions that promote access to health care for the indigent. Lessons learned The lessons learned with regard to knowledge transfer and partnerships between researchers and associated decision-makers are: i involve potential users of the
Full Text Available Reducing Emissions from Deforestation and Degradation (REDD+ is a policy instrument meant to mitigate climate change while also achieving poverty reduction in tropical countries. It has garnered critics for homogenising environmental and development governance and for ignoring how similar efforts have tended to exacerbate gender inequalities. Nonetheless, regarding such schemes as inevitable, some feminists argue for requirements that include women′s empowerment and participation. In this paper we move beyond discussions about safeguards and examine whether the very framing of REDD+ programs can provide openings for a transformation as argued for by its proponents. Following the REDD+ policy process in Burkina Faso, we come to two important insights: REDD+ is a solution in need of a problem. Assumptions about gender are at the heart of creating ′actionable knowledge′ that enabled REDD+ to be presented as a policy solution to the problems of deforestation, poverty and gender inequality. Second, despite its ′safeguards′, REDD+ appears to be perpetuating gendered divisions of labour, as formal environmental decision-making moves upwards; and responsibility and the burden of actual environmental labour shifts further down in particularly gendered ways. We explore how this is enabled by the development of policies whose stated aims are to tackle inequalities.
Full Text Available Background: In several African cities the prevalence of unmarried cohabitation among youth has risen considerably. Because of its potentially negative implications for women and their children, in some countries cohabitation has even become a matter of heated public debate and policy concern. In contrast to industrialized countries, however, the choice between marriage and cohabitation in the region has attracted little attention. Objective: The purpose of the study is to explore the rising phenomenon of young, unmarried, cohabiting couples in Ouagadougou, the capital city of Burkina Faso, and to evaluate how characteristics of both partners involved in a dating relationship affect the choice between marriage and non-marital cohabitation when forming a first union. Methods: Based on life history data including unique relationship biographies, the study takes a competing risks approach to examine relationship transitions to a first marriage or unmarried cohabitation. Results: A long spell of unmarried cohabitation is common among youth in Ouagadougou today, and children's exposure to cohabitation is high. While occupation, especially male occupation, is a crucial determinant of entry into union - having a similar effect on marriage and cohabitation risks - partners' educational attainment, ethnic endogamy, and religion significantly affect the choice between marriage and cohabitation. Conclusions: Ideational changes rather than economic ones motivate youth to choose cohabitation instead of marriage. Cohabitation in Ouagadougou has not become the "poor man's wedding", as Oppenheimer's hypothesis would suggest, but rather the preferred choice of dating couples who are more willing and able to distance themselves from familial expectations and marital norms.

Aqueous acetone extracts prepared from five Indigofera species of Burkina Faso, namely Indigofera colutea (Burm.) Murril., I. macrocalyx Guilld et Perr., I. nigritana Hook f., I. pulchra willd. and I. tinctoria L., were investigated for their phytochemical composition and their antioxidant activities. Standard methods and TLC were used to screen the phytochemical composition. The total phenolic and flavonoid content of extracts were assessed by Folin-Ciocalteu and AlCl3 methods, respectively. These extracts were also evaluated for their antioxidant potentials using ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonate) (ABTS) assays. Flavonoids, saponins, quinones, sterols/triterpenes and tannins were present in all these species except for I. pulchra where quinones were not found. Gallic acid, caffeic acid, rutin and myricetin in I. colutea; gallic acid, quercitrin, myricetin in I. tinctoria; galangin and myricetin in I. macrocalyx were identified by thin layer chromatography. Among these, I. colutea, I. tinctoria, I. nigritana and I. macrocalyx, which had the highest phenolic content, were also found to possess the best antioxidant activities. The results indicated a good correlation between antioxidant activities and total phenolic content (puses. PMID:18817242
Full Text Available Objective. This study aimed to investigate the association between three polymorphisms of renin-angiotensin system and the essential hypertension in the population of Burkina Faso. Methodology. This was a case-control study including 202 cases and 204 matched controls subjects. The polymorphisms were identified by a classical and a real-time PCR. Results. The AGT 235M/T and AT1R 1166A/C polymorphisms were not associated with the hypertension while the genotype frequencies of the ACE I/D polymorphism between patients and controls (DD: 66.83% and 35.78%, ID: 28.22% and 50.98%, II: 4.95% and 13.24%, resp. were significantly different (p < 10−4. The genotype DD of ACE gene (OR = 3.40, p < 0.0001, the increasing age (OR = 3.83, p < 0.0001, obesity (OR = 4.84, p < 0.0001, dyslipidemia (OR = 3.43, p = 0.021, and alcohol intake (OR = 2.76, p < 0.0001 were identified as the independent risk factors for hypertension by multinomial logistic regression. Conclusion. The DD genotype of the ACE gene is involved in susceptibility to hypertension. Further investigations are needed to better monitor and provide individualized care for hypertensive patients.

In the early 1980s, the situation on the northern part of the Central Plateau of Burkina Faso was characterized by expanding cultivation on lands marginal to agriculture, declining rainfall, low and declining cereal yields, disappearing and impoverishing vegetation, falling ground-water levels and strong outmigration. This crisis situation provoked two reactions. Farmers, as well as technicians working for non-governmental organizations, started to experiment in improving soil and water conservation (SWC) techniques. When these experiments proved successful, donor agencies rapidly designed SWC projects based on simple, effective techniques acceptable to farmers. A study looked at the impact of SWC investments in nine villages and identified a number of major impacts, including: significant increases in millet and sorghum yields since the mid-1980s, cultivated fields treated with SWC techniques have more trees than 10-15 years ago, but the vegetation on most of the non-cultivated areas continues to degrade, greater availability of forage for livestock, increased investment in livestock by men and women and a beginning change in livestock management from extensive to semi-intensive methods, improved soil fertility management by farmers, locally rising ground-water tables, a decrease in outmigration and a significant reduction in rural poverty. Finally, data are presented on the evolution of land use in three villages between 1968 and 2002. ?? 2005 Elsevier Ltd. All rights reserved.

The regionally correlated and dated regolith-paleolandform sequence of Sub-Saharan West Africa offers a unique opportunity to constrain continental-scale regolith dynamics as the key part of the sediment routing system. In this study, a regolith mapping protocol is developed and applied at the scale of Southwestern Burkina Faso. Mapping combines field survey and remote sensing data to reconstruct the topography of the last pediplain that formed over West Africa in the Early and Mid-Miocene (24-11 Ma). The nature and preservation pattern of the pediplain are controlled by the spatial variation of bedrock lithology and are partitioned among large drainage basins. Quantification of pediplain dissection and drainage growth allows definition of a cratonic background denudation rate of 2 m/My and a minimum characteristic timescale of 20 Ma for shield resurfacing. These results may be used to simulate minimum export fluxes of drainage basins of constrained size over geological timescales. Background cratonic denudation results in a clastic export flux of ~ 4 t/km2/year, which is limited by low denudation efficiency of slope processes and correlatively high regolith storage capacity of tropical shields. These salient characteristics of shields' surface dynamics would tend to smooth the riverine export fluxes of shields through geological time.
Full Text Available The aim of the present study was to evaluate some enzymes inhibitory effects of 11 plant species belonging to 9 families from Burkina Faso. Methanolic extracts were used for their Glutathione-s-transferase (GST, Acetylcholinesterase (AChE, Carboxylesterase (CES and Xanthine Oxidase (XO inhibitory activities at final concentration of 100 μg mL-1. The total phenolics, flavonoids and tannins were also determined spectrophotometrically using Folin-Ciocalteu, AlCl3 and ammonium citrate iron reagents, respectively. Among the 11 species tested, the best inhibitory percentages were found with Euphorbia hirta, Sclerocarya birrea and Scoparia dulcis (inhibition>40% followed by Annona senegalensis, Annona squamosa, Polygala arenaria and Ceratotheca sesamoides (inhibition>25%. The best total phenolic and tannin contents were found with S. birrea with 56.10 mg GAE/100 mg extract and 47.75 mg TAE/100 mg extract, respectively. E hirta presented the higher total flavonoids (9.96 mg QE/100 mg extract. It's was found that Sclerocarya birrea has inhibited all enzymes at more than 30% and this activity is correlated to total tannins contents. Contrary to S. birrea, the enzymatic activities of E. hirta and S. dulcis are correlated to total flavonoids contents. Present findings suggest that the methanolic extracts of those plant species are potential inhibitors of GST, AChE, CES and XO and confirm their traditional uses in the treatment of mental disorders, gout, painful inflammations and cardiovascular diseases.
Full Text Available A survey of the parasites of abomasa, small, and large intestines of 94 bovines conveyed to the main slaughterhouse of Ouagadougou from the central and northern part of Burkina Faso allowed the identification of nine different worm species: Cooperia punctata, Cooperia pectinata, Haemonchus contortus, Trichostrongylus colubriformis, Bunostomum phlebotomum, Moniezia expensa, Avitellina sp., Oesophagostomum radiatum, and Trichuris sp. By far, Cooperia sp. was the most prevalent (89.4/, followed by H. contortus (66/, and O. radiatum (42.6/. The other worm species were much less prevalent. While only one cattle was free of parasites, it was noticed that polyparasitism was very common. There was a wide range of worm burden (0 to 42290 with however in most animals high worm numbers specially of Cooperia sp. This study confirmed that the rainy season constitutes a period of worm explosion. During the hot and dry season, H. contortus seemed primarily able to undergo arrested development in the L4 stage and secondarily to remain in the adult stage. Statistical analyses of levels of infestation did not show any significant difference according to age, sex, and weight of cattle.

Objective:To identify Candida species in asymptomatic subjects in Bobo-Dioulasso (Burkina Faso) by the matrix-assisted laser desorption ionization-time of flight mass spectrometry. Methods: A cross-sectional study was conducted from January to February 2013 in Bobo-Dioulasso to collect fecal and urine specimens from voluntary donors. Fungal strains were isolated on Sabouraud dextrose agar and analyzed using matrix-assisted laser desorption ionisation-time-of-flight mass spectrometry. Results: A total of 135 samples including stools (78.5%, 106/135) and urine (21.5%, 29/135) were analyzed. The results revealed that fecal specimens contained mainly Candida krusei (C. krusei) (42.5%) followed by Candida albicans (29.3%), Candida glabrata (18.0%) and Candida tropicalis (C. tropicalis) (4.7%). C. krusei (34.6%) was also found to be the most frequently identified in urine samples followed by Candida albicans (27.0%), C. tropicalis (15.4%) and Candida parapsilosis. However, uncommon species such as Candida nivariensis, Candida kefyr, Candida norvegensis, Candida parapsilosis, Candida lusitaniae and Candida robusta were also identified from fecal and urines samples. Conclusions:This study noted the emergence of species such as C. krusei, Candida glabrata, Candida parapsiolosis, C. tropicalis, Candida nivariensis, Candida norvegensis, and others. It is an imperative to take into account the existence of these species in the therapeutic management of patients in Bobo-Dioulasso.

Background Taenia solium, a zoonotic infection transmitted between humans and pigs, is considered an emerging infection in Sub-Saharan Africa, yet individual and community-level factors associated with the human infection with the larval stages (cysticercosis) are not well understood. This study aims to estimate the magnitude of association of individual-level and village-level factors with current human cysticercosis in 60 villages located in three Provinces of Burkina Faso. Methodology/Principal Findings Baseline cross-sectional data collected between February 2011 and January 2012 from a large community randomized-control trial were used. A total of 3609 individuals provided serum samples to assess current infection with cysticercosis. The association between individual and village-level factors and the prevalence of current infection with cysticercosis was estimated using Bayesian hierarchical logistic models. Diffuse priors were used for all regression coefficients. The prevalence of current cysticercosis varied across provinces and villages ranging from 0% to 11.5%. The results obtained suggest that increased age, being male and consuming pork as well as a larger proportion of roaming pigs and percentage of sand in the soil measured at the village level were associated with higher prevalences of infection. Furthermore, consuming pork at another village market had the highest increased prevalence odds of current infection. Having access to a latrine, living in a household with higher wealth quintiles and a higher soil pH measured at the village level decreased the prevalence odds of cysticercosis. Conclusions/Significance This is the first large-scale study to examine the association between variables measured at the individual-, household-, and village-level and the prevalence odds of cysticercosis in humans. Factors linked to people, pigs, and the environment were of importance, which further supports the need for a One Health approach to control

We examine how southwestern Burkina Faso populations interpret political ecological and social change for the past 40 years to assert a changing epidemiology of childhood "cold fevers"-malaria-like illnesses. Lay knowledge about "cold fevers" is historically produced, reflecting political economic, social, ecological and biomedical changes, and the historical consciousness of people living with these illnesses. While informants insisted that dislocations wrought by a post-colonial irrigation scheme increased cold fevers, they offered different explanations for their increased incidence and intensity. This historical epidemiology of cold fevers may influence parents' care decisions, but global public health interventions are rapidly changing therapeutic access. PMID:21507704
Full Text Available We report herein the case of 19-year-old female farmer who suffered a double snakebite on the right foot. After an unsuccessful traditional treatment, she consulted a health center, 48 hours after the bite. Upon arrival at the hospital, she showed signs of severe damage, including hemorrhagic syndrome, extensive gangrene of the bitten limb and severe acute renal failure. Due to financial constraints, neither antivenom nor the scheduled amputation was performed. After 35 days of hospitalization, she returned home, against the advice of medical personnel. Our case summarizes the daily challenges of patients and practitioners that suffer snakebite envenomation in Bobo-Dioulasso, western Burkina Faso.

Full Text Available Abstract Background Vitamin A (VA deficiency is widespread in sub-Saharan Africa and school-age children are a vulnerable group. In Burkina Faso, the production and consumption of red palm oil (RPO is being promoted as a food supplement for VA. The objective of the study was to assess the impact on serum retinol of adding RPO to school lunch in two test zones of Burkina Faso. Methods Over one school year, 15 ml RPO was added to individual meals 3 times a week in selected primary schools in two sites. Serum retinol was measured with HPLC at baseline and exactly 12 months later to take account of seasonality. A simple pre-post test design was used in the Kaya area (north-central Burkina, where 239 pupils from 15 intervention schools were randomly selected for the evaluation. In Bogandé (eastern Burkina, 24 schools were randomised for the controlled intervention trial: 8 negative controls (G1 with only the regular school lunch; 8 positive controls (G2 where the pupils received a single VA capsule (60 mg at the end of the school year; and 8 schools with RPO through the school year (G3. A random sample of 128 pupils in each school group took part in the evaluation. Results In Kaya, serum retinol went from 0.77 ± 0.37 μmol/L at baseline to 1.07 ± 0.40 μmol/L one year later (p Conclusion RPO given regularly in small amounts appears highly effective in the reduction of VA deficiency. RPO deserves more attention as a food supplement for VA and as a potential source of rural income in Sahelian countries.
Full Text Available Abstract Background Burkina Faso's immunization program has benefited regularly from national and international support. However, national immunization coverage has been irregular, decreasing from 34.7% in 1993 to 29.3% in 1998, and then increasing to 43.9% in 2003. Undoubtedly, a variety of factors contributed to this pattern. This study aims to identify both individual and systemic factors associated with complete vaccination in 1998 and 2003 and relate them to variations in national and international policies and strategies on vaccination of rural Burkinabé children aged 12-23 months. Methods Data from the 1998 and 2003 Demographic and Health Surveys and the Ministry of Health's 1997 and 2002 Statistical Yearbooks, as well as individual interviews with central and regional decision-makers and with field workers in Burkina's healthcare system, were used to carry out a multilevel study that included 805 children in 1998 and 1,360 children in 2003, aged 12-23 months, spread over 44 and 48 rural health districts respectively. Results In rural areas, complete vaccination coverage went from 25.9% in 1998 to 41.2% in 2003. District resources had no significant effect on coverage and the impact of education declined over time. The factors that continued to have the greatest impact on coverage rates were poverty, with its various dimensions, and the utilization of other healthcare services. However, these factors do not explain the persistent differences in complete vaccination between districts. In 2003, despite a trend toward district homogenization, differences between health districts still accounted for a 7.4% variance in complete vaccination. Conclusion Complete vaccination coverage of children is improving in a context of worsening poverty. Education no longer represents an advantage in relation to vaccination. Continuity from prenatal care to institutional delivery creates a loyalty to healthcare services and is the most significant and

The Sahel—the belt of land that stretches across Africa on the southern edge of the Sahara—has always been a tough place to farm. Rainfall is low and droughts are frequent. The crust of hard soil is, at times, almost impermeable, and harsh winds threaten to sweep away everything in their path. Over the past three decades, however, hundreds of thousands of farmers in Burkina Faso and Niger have transformed large swaths of the region’s arid landscape into productive agricultural land, improving food security for about 3 million people. Once-denuded landscapes are now home to abundant trees, crops, and livestock. Although rainfall has improved slightly from the mid-1990s relative to earlier decades, indications are that farmer management is a stronger determinant of land and agroforestry regeneration. Sahelian farmers achieved their success by ingeniously modifying traditional agroforestry, water, and soil-management practices. To improve water availability and soil fertility in Burkina Faso’s Central Plateau, farmers have sown crops in planting pits and built stone contour bunds, which are stones piled up in long narrow rows that follow the contours of the land in order to capture rainwater runoff and soil. These practices have helped rehabilitate between 200,000 and 300,000 hectares of land and produce an additional 80,000 tons of food per year. In southern Niger, farmers have developed innovative ways of regenerating and multiplying valuable trees whose roots already lay underneath their land, thus improving about 5 million hectares of land and producing more than 500,000 additional tons of food per year. While the specific calculations of farm-level benefits are subject to various methodological and data limitations, the order of magnitude of these benefits is high, as evidenced by the wide-scale adoption of the improved practices by large numbers of farmers. Today, the agricultural landscapes of southern Niger have considerably more tree cover than they
Full Text Available Abstract Background As more point of care diagnostics become available, the need to transport and store perishable medical commodities to remote locations increases. As with other diagnostics, malaria rapid diagnostic tests (RDTs must be highly reliable at point of use, but exposure to adverse environmental conditions during distribution has the potential to degrade tests and accuracy. In remote locations, poor quality diagnostics and drugs may have significant negative health impact that is not readily detectable by routine monitoring. This study assessed temperature and humidity throughout supply chains used to transport and store health commodities, such as RDTs. Methods Monitoring devices capable of recording temperature and humidity were deployed to Burkina Faso (8, Senegal (10, Ethiopia (13 and the Philippines (6 over a 13-month period. The devices travelled through government supply chains, usually alongside RDTs, to health facilities where RDTs are stored, distributed and used. The recording period spanned just over a year, in order to avoid any biases related to seasonal temperature variations. Results In the four countries, storage and transport temperatures regularly exceeded 30.0°C; maximum humidity level recorded was above 94% for the four countries. In three of the four countries, temperatures recorded at central storage facilities exceeded pharmaceutical storage standards for over 20% of the time, in another case for a majority of the time; and sometimes exceeded storage temperatures at peripheral sites. Conclusions Malaria RDTs were regularly exposed to temperatures above recommended limits for many commercially-available RDTs and other medical commodities such as drugs, but rarely exceeded the recommended storage limits for particular products in use in these countries. The results underline the need to select RDTs, and other commodities, according to expected field conditions, actively manage the environmental conditions in
Full Text Available Abstract Background As Anopheles funestus is one of the principal Afro-tropical malaria vectors, a more complete understanding of its population structure is desirable. In West and Central Africa, An. funestus population structure is complicated by the coexistence of two assortatively mating chromosomal forms. Effective population size (Ne is a key parameter in understanding patterns and levels of intraspecific variation, as it reflects the role of genetic drift. Here, Ne was estimated from both chromosomal forms, Kiribina and Folonzo, in Burkina Faso. Methods Short-term Ne was estimated by evaluating variation at 16 microsatellite loci across temporal samples collected annually from 2000–2002. Estimates were based on standardized variance in allele frequencies or a maximum likelihood method. Long-term Ne was estimated from genetic diversity estimates using mtDNA sequences and microsatellites. Results For both forms, short-term and long-term Ne estimates were on the order of 103 and 105, respectively. Long-term Ne estimates were larger when based on loci from chromosome 3R (both inside and outside of inversions than loci outside of this arm. Conclusion Ne values indicate that An. funestus is not subject to seasonal bottlenecks. Though not statistically different because of large and overlapping confidence intervals, short-term Ne estimates were consistently smaller for Kiribina than Folonzo, possibly due to exploitation of different breeding sites: permanent for Folonzo and intermittent for Kiribina. The higher long-term Ne estimates on 3R, the arm carrying the two inversions mainly responsible for defining the chromosomal forms, give natural selection broader scope and merit further study.
Full Text Available Background: Family structure and union dissolution has been one of the most thoroughly studied determinants of children's wellbeing worldwide. To date, however, few of these studies have examined sub-Saharan Africa, especially countries in West Africa where marital breakdowns are not uncommon. Objective: We attempt to examine the effects of a mother's divorce and widowhood on children's risk of mortality under age 5 and on their probability of entering primary school. Methods: Survival data analysis methods, specifically Kaplan-Meier and piecewise exponential models, are used for analysis, based on data come from the 2000 Migration and Urban Integration Survey of Burkina Faso. Results: Compared to those of intact families, children of divorced parents experience higher estimated mortality risks under age 5 and a lower probability of entering school, even after controlling for various other factors. This effect is large and significant during the first two years after the divorce. The death of the father is also found to greatly reduce a child's likelihood of entering school, but its effect on mortality is not significant. Conclusions: The results indicate that the family context plays an important role in determining two important aspects of children's welfare: their probabilities of dying before age 5 and of entering school. Comments: Children of divorced parents or a deceased father are living in precarious situations and their specific needs should be taken into account in policies in order to improve the wellbeing of all children. Attention must be directed to the first two years following the union dissolution.

We study the spatial geography of schistosomiasis in the african context of Burkina Faso by means of a spatially explicit model of disease dynamics and spread. The relevance of our work lies in its ability to describe quantitatively a geographic stratification of the disease burden capable of reproducing important spatial differences, and drivers/controls of disease spread. Among the latters, we consider specifically the development and management of water resources which have been singled out empirically as an important risk factor for schistosomiasis. The model includes remotely acquired and objectively manipulated information on the distributions of population, infrastructure, elevation and climatic drivers. It also includes a general description of human mobility and addresses a first-order characterization of the ecology of the intermediate host of the parasite causing the disease based on maximum entropy learning of relevant environmenal covariates. Spatial patterns of the disease were analyzed about their disease-free equilibrium by proper extraction and mapping of suitable eigenvectors of the Jacobian matrix subsuming all stability properties of the system. Human mobility was found to be a primary control of both pathogen invasion success and of the overall distribution of disease burden. The effects of water resources development were studied by accounting for the (prior and posterior) average distances of human settlements from water bodies that may serve as suitable habitats to the intermediate host of the parasite. Water developments, in combination with human mobility, were quantitatively related to disease spread into regions previously nearly disease-free and to large-scale empirical incidence patterns. We concluded that while the model still needs refinements based on field and epidemiological evidence, the framework proposed provides a powerful tool for large-scale, long-term public health planning and management of schistosomiasis.
Full Text Available Background: Resistance of malaria parasites to existing drugs complicates treatment, but an antimalarial vaccine that could protect against this disease is not yet available. It is therefore necessary to find new effective and affordable medicines. Medicinal plants could be a potential source of antimalarial agents. Some medicinal plants from Burkina Faso were evaluated for their antiplasmodial and cytotoxic properties in vitro.Methods: Crude dichloromethane, methanol, water-methanol, aqueous and alkaloids extracts were prepared for 12 parts of 10 plants. Chloroquine-resistant malaria strain K1 was used for the in vitro sensibility assay. The Plasmodium lactacte dehydrogenase technique was used to determine the 50% inhibitory concentration of parasites activity (IC50. The cytotoxic effects were determined with HepG2 cells, using the tetrazolium-based colorimetric technique, and the selectivity index (SI was calculated.Results: Sixty crude extracts were prepared. Seven extracts from Terminalia avicenoides showed IC50 < 5 µg/mL. The IC50 of dichloromethane, methanol, aqueous and alkaloids extracts ranged between 1.6 µg/mL and 4.5 µg/mL. Three crude extracts from Combretum collinum and three from Ficus capraefolia had an IC50 ranging between 0.2 µg/mL and 2.5 µg/mL. Crude extracts from these three plants had no cytotoxic effect, with SI > 1. The other plants have mostly moderate or no antimalarial effects. Some extracts from Cordia myxa, Ficus capraefolia and Opilia celtidifolia showed cytotoxicity, with an SI ranging between 0.4 and 0.9.Conclusion: Our study showed a good antiplasmodial in vitro activity of Terminalia avicenoides, Combretum collinum and Ficus capraefolia. These three plants may contain antiplasmodial molecules that could be isolated by bio-guided phytochemical studies.
Full Text Available Burkina Faso is actively pursuing the implementation of Integrated Water Resources Management (IWRM in its development plans. Several policy and institutional mechanisms have been put in place, including the adoption of a national IWRM action plan (PAGIRE and the establishment so far of 30 local water management committees (Comités Locaux de l’Eau, or CLE. The stated purpose of the CLE is to take responsibility for managing water at sub-basin level. The two case studies discussed in this paper illustrate gaps between the policy objective of promoting IWRM on the one hand, and the realities associated with its practical on-the-ground implementation on the other. A significant adjustment that occurred in practice is the fact that the two CLE studied have been set up as entities focused on reservoir management, whereas it is envisioned that a CLE would constitute a platform for sub-basin management. This reflects a concern to minimise conflict and optimally manage the country’s primary water resource and illustrates the type of pragmatic actions that have to be taken to make IWRM a reality. It is also observed that the local water management committees have not been able to satisfactorily address questions regarding access to, and allocation of, water, which are crucial for the satisfactory functioning of the reservoirs. Water resources in the reservoirs appear to be controlled by the dominant user. In order to correct this trend, measures to build mutual trust and confidence among water users 'condemned' to work together to manage their common resource are suggested, foremost of which is the need to collect and share reliable data. Awareness of power relationships among water user groups and building on functioning, already existing formal or informal arrangements for water sharing are key determinants for successful implementation of the water reform process underway.

Full Text Available Abstract Background The ethical discourse about HIV testing has undergone a profound transformation in recent years. The greater availability of antiretroviral therapy (ART has led to a global scaling up of HIV testing and counseling as a gateway to prevention, treatment and care. In response, critics raised important ethical questions, including: How do different testing policies and practices undermine or strengthen informed consent and medical confidentiality? How well do different modalities of testing provide benefits that outweigh risks of harm? To what degree do current testing policies and programs provide equitable access to HIV services? And finally, what lessons have been learned from the field about how to improve the delivery of HIV services to achieve public health objectives and protections for human rights? This article reviews the empirical evidence that has emerged to answer these questions, from four sub-Saharan African countries, namely: Burkina Faso, Kenya, Malawi and Uganda. Discussion Expanding access to treatment and prevention in these four countries has made the biomedical benefits of HIV testing increasingly clear. But serious challenges remain with regard to protecting human rights, informed consent and ensuring linkages to care. Policy makers and practitioners are grappling with difficult ethical issues, including how to protect confidentiality, how to strengthen linkages to care, and how to provide equitable access to services, especially for most at risk populations, including men who have sex with men. Summary The most salient policy questions about HIV testing in these countries no longer address whether to scale up routine PITC (and other strategies, but how. Instead, individuals, health care providers and policy makers are struggling with a host of difficult ethical questions about how to protect rights, maximize benefits, and mitigate risks in the face of resource scarcity.
This paper reports the results of monitoring of medical workers occupationally exposed to ionizing radiation as a consequence of exposure to X-rays, from 2007 to 2010, in Burkina Faso. The radiation exposure monitoring was made with thermoluminescent dosimeters (TLD-100) type 0110 and the reader used was Harshaw 4500. The medical establishments. subscribers were provided with personal dosimeters (measuring Hp (10) and Hp (0.07)) and dosimeters for background and workplace exposure (H*10) measurement. The dosimeters have been worn for periods of 2 months each. The number of establishments subscribed and workers monitored has gradually increased from 4 radiology establishments with 13 workers monitored at September 2007 to 23 subscribers with 121 workers monitored at the end of April 2010. 13 establishments were still working without monitoring. From September 2007 to April 2010, no individual annual dose limit has really been reached. 88.16% of the 2 months dose values of personal dosimeters were below 0.1mSv, the detection limit and 96.61% of Hp (10) bimonthly values were below 3.33mSv. The workplace exposure monitoring values were often low (varying from 0.00mSv to 40.45mSv). 87.08% of the values of H*(10) were below 3.33mSv, the upper limit of Hp (10) for a period of 2 months. Low values of individual dose have also been recorded despite of high values of workplace monitoring. This allowed to state that the workers monitored were not exposed to a major risk. Nevertheless, 13 TLD have been lost and 3 damaged by subscribers (out of 1504 TLD provided). 26 times (out of 240), background measurement and workplace exposure monitoring dosimeters have been placed at the improper location. Therefore, sensitization of the establishments using ionizing radiation should be reinforced and the national regulations should impose radiation monitoring (author)
South-West Burkina Faso (60 000 km2) is located in the upstream parts at the junction of the water basins of the rivers Comoe, Volta and Niger. The mean precipitation value is around 1000 mm in one rainy season (monsoon) starting April and finishing October. More than 80% of precipitation occur between June and August. In our area two great lithological units are encountered: the sedimentary deposits in the West, mainly sandstones of the Upper Precambrian and the crystalline and metamorphic substratum in the East. Our main concern dealt with the sedimentary aquifers within 9 well defined geological formations on the edge of the Taoudeni basin dipping less than 10o NNW. These watersheds have an important hydric potential in surface waters as well as in groundwaters and still embrace nowadays relatively important reclamation lands. The physical context and the water reserve in the southwest present a possibility of expansion and development which has already started being exploited. Since 1970 this region has undertaken an intense activity of mobilization and use of the waters. It has been noted that the managing and exploitation of the important natural potential occurs spontaneously and/or individually without enough critical concern related to the needs and the resources. This situation has already led in some places to shortages, conflicts about the uses and risks of overexploitation of the areas and in an inadequate use of the reclamation lands. This situation implies serious problems as to the qualitative protection of the resource. This inappropriate approach is the consequence of an incomplete knowledge of the water resources. Today new demands arise as to the mobilization the use of the groundwater resources and to the qualitative protection. In order to solve these problems as quickly as possible, from 1997 to 1999 isotopic investigation have been undertaken (18O enables to identify the recharge areas. 14C and 3H define the ''age'' of the water)

The major part of the population of Ouagadougou, Burkina Faso, have their breakfast, dinner and lunch in street food shops. The characteristics of street food vendors are indicated. It appeared clearly that women play a major part (75%) in street food sale. Vendors have only a slight knowledge of food processing and of hygienic practices. There is a high proportion (about 50%) of people among them. This dietary habit has some negative aspects on the consumers' health. Ours studies clearly showed that hygienic practices during sales operations are not respected by all categories of vendors of food products. Also, it was observed that street food vendors sometimes sit close to the waste water drainage system and solid wastes. Sometimes, the food is not covered and it is manipulated by consumers in areas infested by flies and others insects. The water used to wash the materials is of poor quality. The second aspects of our studies showed that, in most cases, when the safety and hygienic practices were not respected, the food became a true microorganism culture medium under tropical climatic conditions. A table reports microbial analysis and contamination rates of some important street foods consumed in Ouagadougou. In general these results showed the failure of microbial quality of some food which is not preheated (milk product, fruit juice, vegetable, fruit) and in the case of food which is not reheated after a long time of exposition (dry meat and meat on sticks). The presence of Salmonella and Shigella species in some food represents a serious danger for consumers. These aspects were observed with most street food vendors. It probably makes street food the source of most diseases caused by bacteria and other microorganisms. PMID:12626290
Full Text Available Abstract Background A well-functioning referral system is fundamental to primary health care delivery. Understanding the providers' referral decision-making process becomes critical. This study's aim was to assess the correctness of diagnoses and appropriateness of the providers' referral decisions from health centers (HCs to district hospitals (DHs among patients with severe malaria and pneumonia. Methods A record review of twelve months of consultations was conducted covering eight randomly selected HCs to identify severe malaria (SM cases among children under five and pneumonia cases among adults. The correctness of the diagnosis and appropriateness of providers' referral decisions were determined using the National Clinical Guidebook as a 'gold standard'. Results Among the 457 SM cases affecting children under five, only 66 cases (14.4% were correctly diagnosed and of those 66 correctly diagnosed cases, 40 cases (60.6% received an appropriate referral decision from their providers. Within these 66 correctly diagnosed SM cases, only 60.6% were appropriately referred. Among the adult pneumonia cases, 5.9% (79/1331 of the diagnoses were correctly diagnosed; however, the appropriateness rate of the provider's referral decision was 98.7% (78/79. There was only one case that should not have been referred but was referred. Conclusions The adherence to the National Guidelines among the health center providers when making a diagnosis was low for both severe malaria cases and pneumonia cases. The appropriateness of the referral decisions was particularly poor for children with severe malaria. Health center providers need to be better trained in the diagnostic process and in disease management in order to improve the performance of the referral system in rural Burkina Faso.

Insecticidal activity of eight plants collected from Burkina Faso was studied using mosquito (Ochlerotatus triseriatus), Helicoverpa zea and Heliothis virescens larvae and adult white fly (Bemisia tabaci). The n-hexane, ethyl acetate and methanol extracts of Pseudocedrela kotschyi, Strophantus hispidus, Securidaca longepedunculata, Sapium grahamii, Swartzia madagascariensis, Cassia nigricans, Jatropha curcas and Datura innoxia were used in this study. Extracts were tested at 250 microg/mL concentration. All three extracts of C. nigricans, J. curcas (skin and seeds) and D. innoxia exhibited 100% mortality on fourth instar mosquito (O. triseriatus) larvae. In addition, the n-hexane and ethyl acetate extracts of S. hispidus, S. longepedunculata, S. grahamii showed 100% mortality. The ethyl acetate extract of S. madagascariensis was the most active on adult white fly and exhibited 80% mortality. Extracts of all other plants exhibited 30-50% mortality on B. tabaci. In the antifeedant assays against H. zea and H. virescens, the MeOH extracts of C. nigricans, S. madagascarensis and S. hispidus were more effective against H. zea as indicated by 74% larval weight reduction as compared to the control. Since C. nigricans is commonly used in West Africa to protect grain storage from insects, we have characterized the insecticidal components present in its extract. Bioassay directed isolation of C. nigricans leaf extract yielded anthraquinones emodin, citreorosein, and emodic acid and a flavonoid, luteolin. Emodin, the most abundant and active anthraquinone in C. nigricans showed approximately 85% mortality on mosquito larvae Anopheles gambiaea and adult B. tabaci at 50 and 25 microg/mL, respectively, in 24 h. These results suggest that the extract of C. nigricans has the potential to be used as an organic approach to manage some of the agricultural pests. PMID:17478091

In South-West of Burkina Faso, palm wine is produced by spontaneous fermentation of the sap from a specific palm tree Borassus akeassii and plays an important role in people's lives. Saccharomyces cerevisiae is the main agent of this alcoholic fermentation but little is known about the diversity of the isolates from palm. In this work, 39 Saccharomyces cerevisiae strains were isolated from palm wine samples collected from 14 sites in Burkina Faso, as well as 7 isolates obtained from sorghum beer (Dolo) from 3 distant sites. Their diversity was analyzed at 12 microsatellite loci, and compared to the genotypes obtained for other African yeast populations isolated from Cocoa hulks from Ghana, sorghum beer from Ivory Coast, palm wine from Djibouti Republic, and to our database of strains from miscellaneous origins (bread, beer, wine, sake, oaks…). The ploidy of these strains has been assessed as well by flow cytometry. Our results show that B. akeassii palm wine contains a specific yeast population of diploid strains, different from Dolo produced in the same area and from other palm wine strains from Ivory Coast, Nigeria, or Djibouti Republic. In contrast, Dolo strains appeared as a group of related and mainly tetraploid strains despite being isolated from different countries. PMID:26202324

A 35-month cluster randomized controlled trial was conducted in Burkina Faso to test whether a radio campaign focused on child health, broadcast between March 2012 and January 2015, could reduce under-5 mortality. This paper describes the design and implementation of the mass media intervention in detail, including the Saturation+ principles that underpinned the approach, the creative process, the lessons learned, and recommendations for implementing this intervention at scale. The Saturation+ approach focuses on the 3 core principles of saturation (ensuring high exposure to campaign messages), science (basing campaign design on data and modeling), and stories (focusing the dramatic climax on the target behavior) to maximize the impact of behavior change campaigns. In Burkina Faso, creative partnerships with local radio stations helped us obtain free airtime in exchange for training and investing in alternative energy supplies to solve frequent energy problems faced by the stations. The campaign used both short spots and longer drama formats, but we consider the short spots as a higher priority to retain during scale-up, as they are more cost-effective than longer formats and have the potential to ensure higher exposure of the population to the messages. The implementation research synthesized in this paper is designed to enable the effective adoption and integration of evidence-based behavior change communication interventions into health care policy and practice.

In Burkina Faso, abortion is legally restricted and socially stigmatised, but also frequent. Unsafe abortions represent a significant public health challenge, contributing to the country's very high maternal mortality ratio. Inspired by an internationally disseminated public health framing of unsafe abortion, the country's main policy response has been to provide post-abortion care (PAC) to avert deaths from abortion complications. Drawing on ethnographic research, this article describes how Burkina Faso's PAC policy emerged at the interface of political and moral negotiations between public health professionals, national bureaucrats and international agencies and NGOs. Burkinabè decision-makers and doctors, who are often hostile to induced abortion, have been convinced that PAC is 'life-saving care' which should be delivered for ethical medical reasons. Moreover, by supporting PAC they not only demonstrate compliance with international standards but also, importantly, do not have to contend with any change in abortion legislation, which they oppose. Rights-based international NGOs, in turn, tactically focus on PAC as a 'first step' towards their broader institutional objective to secure safe abortion and abortion rights. Such negotiations between national and international actors result in widespread support for PAC but stifled debate about further legalisation of abortion. PMID:25132157

The present study evaluates the predictive accuracy of the feed forward backpropagation artificial neural network (BP) in evapotranspiration forecasting from temperature data basis in Dédougou region located in western Burkina Faso, sub-Saharan Africa. BP accuracy is compared to the conventional Blaney–Criddle (BCR) and Reference Model developed for Burkina Faso (RMBF) by referring to the FAO56 Penman–Monteith (PM) as the standard method. Statistically, the models accuracies were evaluated with the goodness-of-fit measures of root mean square error, mean absolute error and coefficient of determination between their estimated and PM observed values. From the statistical results, BP shows similar contour trends to PM, and performs better than the conventional methods in reference evapotranspiration (ET_ref) forecasting in the region. In poor data situation, BP based only on temperature data is much more preferred than the other alternative methods for ET_ref forecasting. Furthermore, it is noted that the BP network computing technique accuracy improves significantly with the addition of wind velocity into the network input set. Therefore, in the region, wind velocity is recommended to be incorporated into the BP model for high accuracy management purpose of irrigation water, which relies on accurate values of ET_ref.

The influence of vetiver grass (Vetiveria zizanioides) on the fate of endosulfan was studied using a vertisol and a lixisol soils from cotton-growing areas of Burkina Faso. Endosulfan adsorption isotherms were prepared for planted and unplanted soils. Pot experiments were then conducted for six months. For both soils, endosulfan adsorption was higher on planted soils (K(f) = 6.53-9.73 mg(l-n) L(n) kg(-1)) than on unplanted soils (6.27-7.24 mg(l-n) L(n) kg(-1)). In unplanted soils, vertisol adsorbed more endosulfan than lixisol. From the pot experiments, the estimated half-lives of endosulfan in unplanted soils (40.6 to 43.1 days) were higher than in planted soils (34.5 to 40.6 days) containing a greater number of endosulfan-degrading microorganisms. Six months after treatment, endosulfan was not detected in soils. The effectiveness of vetiver in promoting adsorption and the disappearance of endosulfan in both studied soils should be validated on the cotton plot scale in Burkina Faso. PMID:24912218
Full Text Available Use of Wild Plants Species in Three Adjoining Village Southern Burkina Faso. Wild species are very important for people in developing countries. To enrich the knowledge of useful wild species, series of ethnobotanical surveys was conducted in three adjoining villages of southern Burkina Faso. This survey has permitted to identify 147 species distributed in 117 genera and 52 families. Woody species represent 60% and grass 40%. Fifty percent of the species used belong to seven families: Poaceae, Caesalpiniaceae, Combretaceae, Mimosaceae, Rubiaceae, Fabaceae and Anacardiaceae. Ninety-seven species are used in medicines, 47 for crafts, 46 for cattle feeding, 40 for human nutrition and 21 to provide fire. In all plants use categories, the calculation of index values showed that there are species that are used more than others. Thus, Sarcocephalus latifolius is the species most commonly used in medicines, Parkia biglobosa in human nutrition, Afzelia africana in cattle feeding, Vitellaria paradoxa in crafts and Detarium microcarpum in wood fuel. The evaluation of the diversity of use revealed that wood species have high diversity of uses than herbaceous. V. paradoxa is the species most diversely used. The top five most used species are V. paradoxa, P. biglobosa, Khaya senegalensis, Tamarindus indica and A. africana. The results of this study provide a database to assess the availability and the evolutionary trend of species widely used in the locality.

Vetiver was chosen to form hedges around the cotton crops and market gardens in Burkina Faso, in order to limit pollutants dispersal towards plants, surface water and groundwater. The influence of vetiver on the fate of two heavy metals (Cu and Cd) and an insecticide (endosulfan) in the soil-water-vetiver system was studied in two representative soils of Burkina Faso, a vertisol and a lixisol. Batch adsorption coefficient measurements, pot and leaching experiments, under phytotronic and outdo...
Full Text Available Abstract Background The use of insecticide-treated nets (ITN is an important tool in the Roll Back Malaria (RBM strategy. For ITNs to be effective they need to be used correctly. Previous studies have shown that many factors, such as wealth, access to health care, education, ethnicity and gender, determine the ownership and use of ITNs. Some studies showed that free distribution and public awareness campaigns increased the rate of use. However, there have been no evaluations of the short- and long-term impact of such motivation campaigns. A study carried out in a malaria endemic area in south-western Burkina Faso indicated that this increased use declined after several months. The reasons were a combination of the community representation of malaria, the perception of the effectiveness and usefulness of ITNs and also the manner in which households are organized by day and by night. Methods PermaNet 2.0® and Olyset® were distributed in 455 compounds at the beginning of the rainy season. The community was educated on the effectiveness of nets in reducing malaria and on how to use them. To assess motivation, qualitative tools were used: one hundred people were interviewed, two hundred houses were observed directly and two houses were monitored monthly throughout one year. Results The motivation for the use of bednets decreased after less than a year. Inhabitants' conception of malaria and the inconvenience of using bednets in small houses were the major reasons. Acceptance that ITNs were useful in reducing malaria was moderated by the fact that mosquitoes were considered to be only one of several factors which caused malaria. The appropriate and routine use of ITNs was adversely affected by the functional organization of the houses, which changed as between day and night. Bednets were not used when the perceived benefits of reduction in mosquito nuisance and of malaria were considered not to be worth the inconvenience of daily use. Conclusion In
Full text: Dispersion of riverine forest Glossina species is of great interest since they are the main cyclical vectors of human and animal trypanosomes in Africa. Design of control and/or eradication programmes requires an accurate knowledge of tsetse ecological preferences and the geographic structure of their populations. In West Africa, in the north of their distribution area, tsetse flies are submitted to the fragmentation of their environments. The level of fragmentation can be estimated from the migration rates between subpopulations. For this purpose, both mark-release field experiments as well as population genetics analyses are the favoured tools. The present study attempts to model the evolution of riverine tsetse flies dispersal in a gallery forest. For savannah species, evolution of tsetse flies dispersal is usually modelled as a two-dimensional random walk (in discrete time and space) or diffusion (its continuous analogue). For riverine species, it could similarly be viewed as one-dimensional random walk. We show that the topology of the whole gallery forest, which is rather a network of tributaries than a straight line, must be taken into account. Moreover, since only a part of the network can be considered in practice, we quantified the effect of partial observation when estimating dispersal parameters. We illustrate these results with a data set from a mark-release experiment carried out with Glossina palpalis gambiensis on a tributary of the Mouhoun River in Burkina Faso. The mark-release protocol is presented. The topology of the gallery is obtained from landsat 7 TM data and modelled as a tree. The predictions of three different models (isotropic and non isotropic random walks on a straight line, isotropic random walk on a network) are compared to field data. The effect of variations in the diffusion coefficient and daily mortality rate on the latter model is analysed. Finally the model is fitted on field data and used to estimate the

L'objectif principal de cette recherche est la mise au point d'une architecture d'integration de donnees socio-bio-geographiques et de donnees satellitales dans un Systeme d'Information Geographique (SIG) en vue d'une aide a la prise de decisions dans un environnement semi-aride au nord du Burkina Faso. Elle repond a la question fondamentale de l'interpretation des effets des facteurs climatiques et socioeconomiques sur le milieu pastoral. La recherche s'est appuyee sur plusieurs hypotheses de travail: possibilite d'utilisation de modele de simulation, d'approche multicritere et de donnees de teledetection dans un cadre de systeme d'information geographique. L'evolution spatiotemporelle des parametres de productivite du milieu a ete evaluee par approche dynamique selon le modele de Wu et al. (1996) qui modelise les interactions entre le climat, le milieu physique, le vegetal et l'animal pour mieux quantifier la biomasse primaire. A ce modele, quatre parametres ont ete integres par approche floue et multicritere afin de prendre en compte la dimension socioeconomique de la productivite pastorale (apport majeur de la recherche): la sante, l'education, l'agriculture et l'eau. La teledetection (imagerie SPOT) a permis de definir la production primaire a partir de laquelle les simulations ont ete realisees sur 10 annees. Les resultats obtenus montrent une bonne correlation entre biomasse primaire in situ et celle calculee pour les deux modeles, avec toutefois une meilleure efficacite du modele modifie (4 fois plus) dans les zones de forte productivite ou l'on note un taux de surexploitation agricole eleve. A cause de la variabilite spatiale de la production primaire in situ, les erreurs des resultats de simulation (8 a 11%) sont acceptables et montrent la pertinence de l'approche grace a l'utilisation des SIG pour la spatialisation et l'integration des differents parametres des modeles. Les types de production secondaire preconises (production de lait pendant 7 mois ou
Full Text Available Abstract Background Despite low endemicity, malaria remains a major health problem in urban areas where a high proportion of fevers are presumptively treated using anti-malarial drugs. Low acquired malaria immunity, behaviour of city-dwellers, access to health care and preventive interventions, and heterogenic suitability of urban ecosystems for malaria transmission contribute to the complexity of the malaria epidemiology in urban areas. Methods The study was designed to identify the determinants of malaria transmission estimated by the prevalence of anti-circumsporozoite (CSP antibodies, the prevalence and density of Plasmodium falciparum infection, and the prevalence of malarial disease in areas of Ouagadougou, Burkina-Faso. Thick blood smears, dried blood spots and clinical status have been collected from 3,354 randomly chosen children aged 6 months to 12 years using two cross-sectional surveys (during the dry and rainy seasons in eight areas from four ecological strata defined according to building density and land tenure (regular versus irregular. Demographic characteristics, socio-economic information, and sanitary and environmental data concerning the children or their households were simultaneously collected. Dependent variables were analysed using mixed multivariable models with random effects, taking into account the clustering of participants within compounds and areas. Results Overall prevalences of CSP-antibodies and P. falciparum infections were 7.7% and 16.6% during the dry season, and 12.4% and 26.1% during the rainy season, respectively, with significant differences according to ecological strata. Malaria risk was significantly higher among children who i lived in households with lower economic or education levels, iii near the hydrographic network, iv in sparsely built-up areas, v in irregularly built areas, vi who did not use a bed net, vii were sampled during the rainy season or ii had traveled outside of Ouagadougou
Full Text Available BACKGROUND: Malariometric parameters are often primary endpoints of efficacy trials of malaria vaccine candidates. This study aims to describe the epidemiology of malaria prior to the conduct of a series of drug and vaccine trials in a rural area of Burkina Faso. METHODS: Malaria incidence was prospectively evaluated over one year follow-up among two cohorts of children aged 0-5 years living in the Saponé health district. The parents of 1089 children comprising a passive case detection cohort were encouraged to seek care from the local health clinic at any time their child felt sick. Among this cohort, 555 children were randomly selected for inclusion in an active surveillance sub-cohort evaluated for clinical malaria during twice weekly home visits. Malaria prevalence was evaluated by cross-sectional survey during the low and high transmission seasons. RESULTS: Number of episodes per child ranged from 0 to 6 per year. Cumulative incidence was 67.4% in the passive and 86.2% in the active cohort and was highest among children 0-1 years. Clinical malaria prevalence was 9.8% in the low and 13.0% in the high season (p>0.05. Median days to first malaria episode ranged from 187 (95% CI 180-193 among children 0-1 years to 228 (95% CI 212, 242 among children 4-5 years. The alternative parasite thresholds for the malaria case definition that achieved optimal sensitivity and specificity (70-80% were 3150 parasites/µl in the high and 1350 parasites/µl in the low season. CONCLUSION: Clinical malaria burden was highest among the youngest age group children, who may represent the most appropriate target population for malaria vaccine candidate development. The pyrogenic threshold of parasitaemia varied markedly by season, suggesting a value for alternative parasitaemia levels in the malaria case defintion. Regional epidemiology of malaria described, Sapone area field centers are positioned for future conduct of malaria vaccine trials.

Assessing landscape and population's dynamics at watershed level contribute to address anthropogenic aspect of climate change issue owing to the close link between LULC and climate changes. The objective of this study is to explore the dependencies of population to land management changes in Massili basin (2612 km²) located in central Burkina Faso. A set of three satellite scenes was acquired for the years 1990 (Landsat 7 ETM), 2002 (Landsat 7 ETM+) and 2013 (Landsat 8 OLI/TIRS) from the Global Land Cover Facility's (GLCF) website. Census data were provided by the National institute of statistics and demographic (INSD). The satellites images were classified using object-oriented classification method which was supported by historic maps and field data. Those were collected in order to allow for class definition, verification and accuracy assessments. Based on the developed land use maps, change analysis was carried out using post classification comparison in GIS. Finally, derived land use changes were compared with census data in order to explore links between population dynamics and the land use changes. It was found in 1990 that Massili watershed LULC was dominated by Tree/shrub savannah (69%, 1802.28 km2 ), Farm/Fallow was representing 22%, Gallery forest (4%), Settlement (3%), Barre soil (1%), Water bodies (1%). In 2002, the major landscape was Farm (54%). Tree/Shrub savannas were reduced to 36% while the Gallery Forest was decreased to1% of the basin area. The situation has also slightly changed in 2013 with an increase of the area devoted to farm/fallow and settlement at a rate of 3% and Gallery forest has increased to 4%. The changes in land use are in agreement with a notable increase in population. The analysis of census data showed that the number of inhabitants increased from 338 inhabitants per km2 in 1990 to 1150 inhabitants per km2 in 2013. As shown by statistical analysis (Kendall correlation tau=0.9), there is a close relation between both dynamics.
In many developing countries a long time series of solar radiation measurements are not often available. This is due to the cost, maintenance and calibration requirements of measuring devices. Consequently, the use of solar energy by Photovoltaic (PV) conversion copes with the choice and the optimization of the PV system. This work concerned the analysis of climate parameters strongly influencing the Photovoltaic (PV) systems energy production and the simulation of an ideal system based on a single PV module. Estimation and analysis of time series of climate parameters covered a set of six weather stations with respect to the three climatic zones in Burkina Faso (BF), over 38 years. The analysis showed that the solar irradiation in BF lies between 3 kWh/m2/day and 7.5 kWh/m2/day. The highest values of the solar irradiation are measured in the Northern part of the country while lowest values are measured in the Southern part. Daily mean temperature for all weather stations was greater than the Standard Test Condition (STC) temperature (25°C) over a long period of the year. Information on solar irradiation and temperature is fundamental for PV systems sizing process. For PV performance evaluation, a simulation is carried out using an ideal system composed of a single PV module from TENESOL Company. This simulation is performed for three classes of climatic conditions 'Mean situation', 'Adverse situation', and 'Beneficial situation', and evaluated for six sitesacross BF. The results revealed intra-annual and spatial variability of Maximum Power (MP). Across BF, MP varied between 60 W/day and 190 W/day in Sahelian zone, between 65 W/day and 185 W/day in soudano-sahelian zone, and between 67 W/day and 208 W/day in Soudanian zone. MP intra-annual variability is higher during the period July-August, mainly for 'Beneficial situation'. The negative effect of temperature on PV energy production is specially amplified in Sahelian zone due to its highest temperatures. This

Most households in Sub-Saharan Africa rely on wood as primary energy source. The availability of wood is decreasing and deforestation is a major ecological problem in Sub-Saharan Africa. The scarcity of wood is demanding for a sustainable solution. The sun seems to provide a good alternative. Solar energy is free, without unhealthy smoke or chances to burns. The idea of using solar energy for cooking is not new: many different techniques have already been tested. Most variants are expensive, and therefore not available for most families in Sub-Saharan Africa. A cheap solar cooking device is the CooKit, a cardboard panel cooker covered with aluminium foil. In the adaptation to the CooKit, as to all innovations, it is important that the users are convinced of the advantages. An important step in the adaptation process is learning how to use the cooking device; the best way to do this is by home practice. Monitoring and evaluating the real use is needed, for it is interesting to know if the CooKit is actually used, and also to find out how women have implemented the new technique in their kitchens. In 2005, the SUPO foundation started a project in Burkina Faso: Programme Energie Solaire Grand-Ouaga (PESGO). The aim of PESGO is to introduce the CooKit in the urban households in Ouagadougou by providing training sessions and home assistance. In this paper, a mid-term review on this small-scale cooking project is presented. The possibilities and challenges of solar cooking are outlined, taking the urban context of Ouagadougou in account. In PESGO, dependence on weather conditions is found to be one of the challenges: if sunrays are blocked by clouds or dust in the air, the cooking will be slowed down. The CooKit cannot replace firewood entirely, and a complementary element has to be found. SUPO is exploring the use of Jatropha oil as a complement to the CooKit. The Jatropha plant is drought tolerant and its fruits contain oil which can be used as fuel substitute. Further
Full Text Available Abstract Background This methodological article is based on a health policy research project conducted in Burkina Faso (West Africa. Concept mapping (CM was used as a research method to understand the local views of equity among stakeholders, who were concerned by the health policy under consideration. While this technique has been used in North America and elsewhere, to our knowledge it has not yet been applied in Africa in any vernacular language. Its application raises many issues and certain methodological limitations. Our objective in this article is to present its use in this particular context, and to share a number of methodological observations on the subject. Methods Two CMs were done among two different groups of local stakeholders following four steps: generating ideas, structuring the ideas, computing maps using multidimensional scaling and cluster analysis methods, and interpreting maps. Fifteen nurses were invited to take part in the study, all of whom had undergone training on health policies. Of these, nine nurses (60% ultimately attended the two-day meeting, conducted in French. Of 45 members of village health committees who attended training on health policies, only eight were literate in the local language (Moore. Seven of these (88% came to the meeting. Results The local perception of equity seems close to the egalitarian model. The actors are not ready to compromise social stability and peace for the benefit of the worst-off. The discussion on the methodological limitations of CM raises the limitations of asking a single question in Moore and the challenge of translating a concept as complex as equity. While the translation of equity into Moore undoubtedly oriented the discussions toward social relations, we believe that, in the context of this study, the open-ended question concerning social justice has a threefold relevance. At the same time, those limitations were transformed into strengths. We understand that it was
Full Text Available Background: National surveys in low-income countries increasingly rely on self-reported measures of health. The ease, speed, and economy of collecting self-reports of health make such collection attractive for rapid appraisals. However, the interpretation of these measures is complicated since different cultures understand and respond to the same question in different ways. Objective: The aim of this pilot study was to develop a culturally sensitive tool to study the self-reported health (SRH of the local adult population in Burkina Faso. Design: The study was carried out in the 2009 rainy season. The sample included 27 men and 25 women aged 18 or older who live in semi-urban Nouna, Burkina Faso. Three culturally adapted instruments were tested: a SRH question, a wooden visual analogue scale (VAS, and a drawn VAS. Respondents were asked to explain their answers to each instrument. The narratives were analyzed with the content analysis technique, and the prevalence of poor SRH was estimated from the quantitative data by stratification for respondent background variables (sex, age, literacy, education, marital status, ethnicity, chronic diseases. The correlation between the instruments was tested with Spearman's correlation test. Results: The SRH question showed a 38.5% prevalence of poor SRH and 44.2% prevalence with both VAS. The correlation between the VAS was 0.89, whereas the correlation between the VAS and the SRH question was 0.60–0.64. Nevertheless, the question used as the basis of each instrument was culturally sensitive and clear to all respondents. Analysis of the narratives shows that respondents clearly differentiated between the various health statuses. Conclusion: In this pilot, we developed and tested a new version of the SRH question that may be more culturally sensitive than its non-adapted equivalents. Additional insight into this population's understanding and reporting of health was also obtained. A larger sample is needed

Full Text Available This study estimates the impact on Burkina Faso of eliminating tariffs on imports from the EU under EPAs, considering trade, revenue and welfare effects. At complete elimination of tariffs on all products imports from trade classification sections (TDC 01-13 from the EU. Burkina Faso is likely to experience both welfare gains and losses depending on the values of imports of each trade classification section in question. The overall welfare effect relative to GDP tends to be very small and positive, but potential tariff revenue losses are enormous even when the country has up to fifteen - twenty-five years in which to implement the tariff reductions, unless with scope for tax substitution. EPAs effects are concentrated on those product sections where trade creation outweighs trade diversion such as Animal products, Vegetable products, Animal/Veg. products, Mineral products, and Textiles products. Besides, product sections with the greatest market opportunities for EU suppliers to displace any of the other suppliers, ECOWAS and/or ROW include sections where trade diversion outweighs trade creation effects, such as prepared foodstuffs, product of chemicals, plastics, raw hides & skin, etc. The sensitive products (SPs to be excluded from tariff removal should include sections in which ECOWAS member nations are suppliers to regional importers so that excluding them as SPs would improve the welfare gain compared to estimates where tariff are removed from those products in which ECOWAS have zero potential. The results at this level of aggregation will provide useful information to the on-going negotiations between ECOWAS and the EU in determining Burkinabe's products to be exempted from tariff removal during EPAs based on the severity of the effects on varied trade classification (TDC sections, among other considerations.
Full Text Available Background: There are more than 40 Health and Demographic Surveillance System (HDSS sites in 19 different countries. The running costs of HDSS sites are high. The financing of HDSS activities is of major importance, and adding external health surveys to the HDSS is challenging. To investigate the ways of improving data quality and collection efficiency in the Nouna HDSS in Burkina Faso, the stand-alone data collection activities of the HDSS and the Household Morbidity Survey (HMS were integrated, and the paper-based questionnaires were consolidated into a single tablet-based questionnaire, the Comprehensive Disease Assessment (CDA. Objective: The aims of this study are to estimate and compare the implementation costs of the two different survey approaches for measuring population health. Design: All financial costs of stand-alone (HDSS and HMS and integrated (CDA surveys were estimated from the perspective of the implementing agency. Fixed and variable costs of survey implementation and key cost drivers were identified. The costs per household visit were calculated for both survey approaches. Results: While fixed costs of survey implementation were similar for the two survey approaches, there were considerable variations in variable costs, resulting in an estimated annual cost saving of about US$45,000 under the integrated survey approach. This was primarily because the costs of data management for the tablet-based CDA survey were considerably lower than for the paper-based stand-alone surveys. The cost per household visit from the integrated survey approach was US$21 compared with US$25 from the stand-alone surveys for collecting the same amount of information from 10,000 HDSS households. Conclusions: The CDA tablet-based survey method appears to be feasible and efficient for collecting health and demographic data in the Nouna HDSS in rural Burkina Faso. The possibility of using the tablet-based data collection platform to improve the quality

The rapid scale-up of human immunodeficiency virus (HIV) testing, counselling and treatment throughout sub-Saharan Africa has raised questions about how to protect patients' rights to consent, confidentiality, counselling and care in resource-constrained settings. The Multi-country African Testing and Counselling for HIV (MATCH) study investigated client and provider experiences with different modes of testing in sub-Saharan Africa. One component of that study was a survey of 275 HIV service providers in Burkina Faso, Kenya and Uganda that gathered quantifiable indicators and qualitative descriptions using a standardized instrument. This article presents provider perspectives on the challenges of obtaining consent, protecting confidentiality, providing counselling and helping clients manage disclosure. It also explores health workers' fear of infection within the workplace and their reports on discrimination against HIV clients within health facilities. HIV care providers in Burkina Faso, Kenya and Uganda experienced substantial rewards from their work, including satisfaction from saving lives and gaining professional skills. They also faced serious resource constraints, including staff shortages, high workloads, lack of supplies and inadequate infrastructure, and they expressed concerns about accidental exposure. Health workers described heavy emotional demands from observing clients suffer emotional, social and health consequences of being diagnosed with HIV, and also from difficult ethical dilemmas related to clients who do not disclose their HIV status to those around them, including partners. These findings suggest that providers of HIV testing and counselling need more resources and support, including better protections against HIV exposure in the workplace. The findings also suggest that health facilities could improve care by increasing attention to consent, privacy and confidentiality and that health policy makers and ethicists need to address some
Full Text Available BACKGROUND: little is known about porcine cysticercosis in Burkina Faso. We conducted a pilot study to estimate the prevalence of antigens of Taenia solium cysticercosis and to identify associated factors in pigs of three villages in Burkina Faso, selected to represent different pig management practices: one village where pigs are allowed to roam freely (Batondo, one village where pigs are penned part of the time (Pabré and one village with limited pig farming (Nyonyogo. METHODS/PRINCIPAL FINDINGS: a clustered random sampling design was used. Data on socio-demographic characteristics (source of drinking water, presence of latrines in the household, type and number of breeding animals and pig management practices were collected using a standardized questionnaire. Blood samples were collected from one pig per household to determine the presence of antigens of the larval stages of T. solium by the B158/B60 Ag-ELISA. The associations between seropositivity and socio-demographic and pig management practices were estimated using logistic regression. Proportions of 32.5% (95% CI 25.4-40.3, 39.6% (31.9-47.8, and 0% of pigs, were found positive for the presence of circulating antigens of T. solium in Batondo, Pabré, and Nyonyogo, respectively. The results of the logistic regression analyses suggested that people acquire knowledge on porcine cysticercosis following the contamination of their animals. The presence of antigens in the pigs' sera was not associated with the absence of latrines in the household, the source of drinking water or the status of infection in humans but was associated with pig rearing practices during the rainy season. CONCLUSIONS/SIGNIFICANCE: the results suggest that education of pig farmers is urgently needed to reduce the prevalence of this infection.
Full Text Available Abstract Background Little is known about the reproductive health of women who survive obstetric complications in poor countries. Our aim was to determine how severe obstetric complications in Burkina Faso affect reproductive events in the first year postpartum. Methods Data were collected from a prospective cohort of women who either experienced life threatening (near-miss pregnancy-related complications or an uncomplicated childbirth, followed from the end of pregnancy to one year postpartum or post-abortum. Documented outcomes include menses resumption, sexual activity resumption, dyspareunia, uptake of contraceptives, unmet needs for contraception and women's reproductive intentions. Participants were recruited in seven hospitals between December 2004 and March 2005 in six towns in Burkina Faso. Results Reproductive events were associated with pregnancy outcome. The frequency of contraceptive use was low in all groups and the method used varied according to the presence or not of a live baby. The proportion with unmet need for contraception was high and varied according to the time since end of pregnancy. Desire for another pregnancy was highest among near-miss women with perinatal death or natural abortion. Women in the near-miss group with induced abortion, perinatal death and natural abortion had significantly higher odds of subsequent pregnancy. Unintended pregnancies were observed mainly in women in the near-miss group with live birth and the uncomplicated delivery group. Conclusions Considering the potential deleterious impact (on health and socio-economic life of new pregnancies in near-miss women, it is important to ensure family planning coverage includes those who survive a severe complication.
Full Text Available Diversification and inter-species integration in rural livestock system in Burkina Faso. The purpose of this study was to determine the level of existing relation between several animal species bred in extensive livestock systems. Data were collected about breeding importance of cattle, sheep, goat and fowl in four villages of the central region of Burkina Faso (Namanegma, Villy-Moukouan, Luili-Nobere and Yambasse. These villages are located in the Soudano-Sahelian agroclimatic zone. Partial correlation and bivariate ordinary least square methods are computed. The results show that livestock practices are related to diversification and species integration strategies of rural households. That is, many households (16.64/ breed four species together, while 6.14/ of households possess one species. Three and two species breeders account for 14.95 and 14.36/ of households respectively. Poultry represents a driving activity in extensive livestock system. From a social welfare standpoint, fowl activity accounts for 49.42/ of households employment. Cattle breeding is the highest stage in this system and represents a kind ofsocioeconomic prestige for the breeder. The four types of livestock are correlated at different levels. Thus, high correlation degrees are noted between poultry and goat (p > 0.50. On the other hand, there is a weak relation between the remote livestock levels (e.g. poultry and cattle, p < 0.50. These results suggest that incentive policies for livestock must take into account breeders strategies. To promote poultry production can create track down effect on the entire livestock system.
Full Text Available Abstract Until 2010, Burkina Faso was an exception to the international trend of abolishing user fees for antiretroviral treatment (ART. Patients were still expected to pay 1,500F CFA (2 Euros per month for ART. Nevertheless, many non-governmental organizations (NGOs exempted patients from payment. The objective of this study was to investigate how NGOs selected the beneficiaries of payment exemptions for government-provided ART and rationed out complementary medical and psychosocial services. For this qualitative study, we conducted 13 individual interviews and three focus group discussions (n = 13 persons with program staff in nine NGOs (4,000 patients, two NGO coordinating structures and one national program. These encounters were recorded and transcribed, and their content was thematically analyzed. The results were presented to the NGOs for feedback. Results indicate that there are no concrete guidelines for identifying patients warranting payment exemptions. Formerly, ART was scarce in Burkina Faso and the primary criterion for treatment selection was clinical. Our results suggest that this scarcity, mediated by an approach we call sociotherapeutic rationality (i.e. maximization of clinical success, may have led to inequities in the provision of free ART. This approach may be detrimental to assuring equity since the most impoverished lack resources to pay for services that maximize clinical success (e.g. viral load that would increase their chances of being selected for treatment. However, once selected into treatment, attempts were made to ration-out complementary services more equitably. This study demonstrates the risks entailed by medication scarcity, which presents NGOs and health professionals with impossible choices that run counter to the philosophy of equity in access to treatment. Amid growing concerns of an international funding retreat for ART, it is important to learn from the past in order to better manage the potentially
Full Text Available Abstract Background Predation of aquatic immature stages has been identified as a major evolutionary force driving habitat segregation and niche partitioning in the malaria mosquito Anopheles gambiae sensu stricto in the humid savannahs of Burkina Faso, West Africa. Here, we explored behavioural responses to the presence of a predator in wild populations of the M and S molecular forms of An. gambiae that typically breed in permanent (e.g., rice field paddies and temporary (e.g., road ruts water collections. Methods Larvae used in these experiments were obtained from eggs laid by wild female An. gambiae collected from two localities in south-western Burkina Faso during the 2008 rainy season. Single larvae were observed in an experimental arena, and behavioural traits were recorded and quantified a in the absence of a predator and b in the presence of a widespread mosquito predator, the backswimmer Anisops jaczewskii. Differences in the proportion of time allocated to each behaviour were assessed using Principal Component Analysis and Multivariate Analysis of Variance. Results The behaviour of M and S form larvae was found to differ significantly; although both forms mainly foraged at the water surface, spending 60-90% of their time filtering water at the surface or along the wall of the container, M form larvae spent on average significantly more time browsing at the bottom of the container than S form larvae (4.5 vs. 1.3% of their overall time, respectively; P P P P Conclusions Behavioural differences between larvae of the M and S form of An. gambiae in response to an acute predation risk is likely to be a reflection of different trade-offs between foraging and predator vigilance that might be of adaptive value in contrasting aquatic ecosystems. Future studies should explore the relevance of these findings under the wide range of natural settings where both forms co-exist in Africa.

In Burkina-Faso, urban vegetable agriculture is often characterized by urban solid waste fertilizer inputs containing heavy metals such as Cu and Cd. Thus, the relevance of surrounding urban vegetable plots with vetiver hedges to reduce environmental pollution by Cu and Cd was investigated by adsorption studies and pot experiments. Vetiver biomass, its metal contents and, its total and MgCl2 extractable soil metals were monitored over 6months in the presence of a mixture of metal at two concentrations: 2-10 and 100-500mgkg(-1), for Cd and Cu, respectively. The Freundlich adsorption coefficient (Kf) values increased after vetiver growth and were significantly higher for vertisol than for lixisol. After 6months, the vetiver that was grown on lixisol accumulated more metal, increasing up to 4635mgkg(-1) for Cu and to 21.8mgkg(-1) for Cd, than did the vetiver that was grown on vertisol, increasing up to 1534mgkg(-1) for Cu and to 7.2mgkg(-1) for Cd. The metal bioconcentration factor, which was significantly higher for Cd, increased with the applied concentration and ranged from 1.6 to 14 for Cu and from 2.3 to 22 for Cd. Additionally, the translocation factors were higher for Cd (0.38-7.3) than for Cu (0.07-2.6), and the translocation was easiest from lixisol than from vertisol. Thus our results demonstrate the ability of vetiver for Cu and Cd phytoremediation in Burkina Faso soils. Nevertheless, these results should be confirmed across the field to advocate the establishment of vetiver hedges. PMID:25065788

We investigated the evolution of Pfcrt K76T mutation five years after the withdrawal of chloroquine in Burkina Faso. A total of 675 clinical isolates collected from October 2010 to September 2012 were successfully genotyped. Single nucleotide polymorphism in Pfcrt (codon 76) gene was analyzed. The prevalence of resistant Pfcrt 76T allele was 20.55%. There was a progressive decrease of the proportion of mutant type pfcrt T76 from 2010 to 2012 (X2=5.508 p=0.0189). Our results suggest a progressive return of the wild type Pfcrt K76 in Burkina Faso but the prevalence of the mutants Pfcrt T76 still remains high. PMID:26516402
SUMMARY Although West Africa shows remarkably low prevalence, AIDS remains a burning issue for the population of Ouagadougou. The capital of Burkina Faso has the highest rates in the country with an HIV prevalence in 2010 of 2.1% among adults aged 15-49, compared to 1% at the national level (UNAIDS 2012:19). Indeed, AIDS is a disease that many people associate with socially unacceptable and condemnable sexual behavior. This study aims to better understand and contextualize the dynamics ...

This thesis aimed at a comprehensive characterization of water and nutrient use and nutrient leaching losses in vegetable production systems in Bobo Dioulasso (Burkina Faso) in view of contributing to the development of more rational advice regarding water and nutrient management. For this purpose, three treatments were compared: farmer’s normal fertilization practice (T100), a 30% reduction in fertilization rates (T70), and unfertilized plots (T0). Crop yield, irrigation water and fertilizer...
The consequences of habitat change for human well-being are assumed to be especially extreme in Burkina Faso. The country is located in a highly drought-sensitive zone of West Africa, and small‐scale subsistence farmers may be especially affected if losses of biodiversity lead to changes in ecosystem functioning; many depend on more or less degraded lands for agricultural production. The overall aim of the present thesis consequently was to characterize the functional traits of soil-organ...

Accumulating evidence indicates that health crises can play a key role in precipitating or exacerbating poverty. For women of reproductive age in low-income countries, the complications of pregnancy are a common cause of acute health crisis, yet investigation of longer-term dynamics set in motion by such events, and their interactions with other aspects of social life, is rare. This article presents findings from longitudinal qualitative research conducted in Burkina Faso over 2004-2010. Guid...
