Background: The need for locally-driven, locally-generated evidence to guide health policy and systems decision-making and implementation in West Africa remains urgent. Thus, health policy and systems research (HPSR) is a field with great potential for addressing many of the sub-region's intransigent health challenges. This paper presents an analysis of trends and patterns of peer-reviewed HPSR publications across the Economic Community of West African States (ECOWAS), to help understand trends and patterns of HPSR publication and the degree of involvement of West African researchers in HPSR evidence generation in the sub-region. Our goal was to use the findings to inform the development of a sub-regional strategy to strengthen HPSR and its use to inform development and improvement of health outcomes.Methods: A scoping review was conducted over a 25-year period from January 1990 to September 2015. Literature searches were conducted in English and French using Google Scholar, PubMed Central and Cairn.info.Results: A total of 258 articles were retrieved. Of these, 246 were statistically analysed, with 54% having West African lead authors. Two thirds of the papers originated from three out of the 15 countries of the ECOWAS, specifically Nigeria (28.86%), Burkina Faso (21.54%) and Ghana (17.07%). Most authors were based in academic institutions and participation of authors from ministries of health, hospitals and non-governmental organisations was limited. English was the predominant language for publication even for papers originating from Francophone West African countries. There has been a progressive increase in publications over the studied period.Conclusion: Despite progressive improvements over time, West Africa remains a weak sub-region in terms of peer-reviewed HPSR publications. Within the overall weakness, there is country-to-country variation. The fact that only a handful of countries accounted for nearly 70% of the total volume of publications in West Africa attests to the great disparities in individual, institutional and contextual capacities for HPSR evidence generation. Bridging the gap between lead institutions (universities and research centres) and the practice community (ministries, hospitals, non-governmental organisations) is indispensable for ensuring the practical use of HPSR evidence. There remains a major need for investments in HPSR capacity building in West Africa. [ABSTRACT FROM AUTHOR]

Background: This paper provides an insightful quantitative ethnoecological analysis and affirms that agro-pastoralists have a multiplicity of criteria for valuating their natural forage resources. Rural households in West Africa are not only confronted with water resource scarcity but also have to cope with limited forage resources to feed livestock in both wet and dry seasons based on local knowledge. Local agro-pastoral social-ecological systems (SESs) in the study areas stem from the daily utilization of available forage resources by dominant domestic livestock (cattle, goats, and sheep) over the years. However, there is very little systematic knowledge documentation on forage-related valuation criteria in this part of the world. Hence, this study aimed at examining (1) forage resources used for different seasons and livestock types, (2) explicit forage-related valuation criteria and associated salience, and (3) effects of socio-demographic and climatic aridity on local valuation criteria. Methods: To address these aims, a total of 526 individual ethnoecological interviews (encompassing Dagbani, Gurunsi, and Mossi ethnic groups) were conducted in 16 villages coupled with vegetation sampling of 144 plots in Ghana and Burkina Faso. Rigorous model selection, generalized linear mixed-effects models, cognitive salience indices, and descriptive statistics were applied. Results: The results revealed that majority (73%) of the agro-pastoralists regarded herbaceous forage plants to be very palatable for livestock consumption in the rainy season and for cattle while woody vegetation and crop-related forage plants were rather perceived to be more important in the dry season and for goats and sheep. The findings also indicated that climatic aridity significantly influenced the number of forage-related valuation criteria cited by agro-pastoralists for different seasonal and livestock types (p < 0.001). It was also found out that agro-pastoralists did not only judge forage plants based on their availability but also on other criteria such as palatability, stimulation of milk production, and healthy growth of livestock. Conclusion: Local agro-pastoralists' knowledge on natural forage resources and their valuation criteria is geared towards sustainable domestic livestock production. This study is thus interesting and crucially important for fellow scientists, policy-makers, and other stakeholders in the agricultural production sector in local farming landscapes within West Africa and beyond.
