Item Insights into the importance of ecosystem services to human well-being in reservoir landscapes(Journal Article, 2019-10) Jones, S.K.; Boundaogo, M.; DeClerck, Fabrice A.J.; Estrada-Carmona, Natalia; Mirumachi, N.; Mulligan, M.Smallholder farmers in West Africa use multiple ecosystem services (ES) in their day-to-day lives. The contribution that these services make to human well-being (HWB), and therefore to development outcomes, is not well understood. We analyse smallholder farmer perceptions of ES, ecosystem disservices (ED), and their HWB importance around community-managed reservoirs in four semi-arid landscapes in West Africa, using participatory mapping, focus groups and face-to-face surveys. Farmers identified what nature-based benefits (ES) and problems (ED) they perceived across each landscape and rated the importance of each service and disservice for their HWB. Our results indicate that ES make an important contribution to HWB in our study sites. More than 80% of farmers rated benefits from plant-based foods, domestic and agricultural water supplies, biofuel, medicinal plants, and fertile soil, and problems associated with human disease vectors, as of high or very high importance for HWB. Multiple ES were identified as contributing to each dimension of HWB, and ED as detracting from health and material well-being. Perceptions of the importance of several ES and ED varied significantly with socio-economic group, highlighting the need for careful consideration of trade-offs between HWB outcomes and stakeholders in ecosystem management decisions to support sustainable development.Item Mapping actors along value chains: integrating visual network research and participatory statistics into value chain analysis(Book, 2017) Stein, C.; Barron, JennieThis report outlines a participatory approach for mapping actors along value chains. The methodology provides novel ideas on how to combine value chain analysis with participatory statistics and visual network research approaches, to generate valuable insights about complex value chains together with local stakeholders in a cost effective way. A framework is introduced, which provides a canvas for mapping actors onto different analytical dimensions relevant in value chain analysis. After outlining some of the conceptual foundations and the methodological approach, a sequence of steps for mapping actors and their relationships is described. The experience from a case study is used to illustrate the steps involved. The case study is on fodder value chains in the Sahelian agro-ecological zone of Burkina Faso, but the mapping approach can be adapted to a range of contexts.Item TAI Project - WP4 Workshops report(Report, 2017) Antona, M.; Daré, W.; Jankowski, F.; Labeyrie, V.; Kizito, FredItem Targeting agricultural innovations and ecosystem services in the Volta Basin(Report, 2017) CGIAR Research Program on Water, Land and EcosystemsItem First WP4 Workshop report in Zebilla(Report, 2017) Antona, M.; Daré, W.; Jankowski, F.Item Mapping reservoirs in the Volta basin(Report, 2017) Mulligan, Mark; Smedley, David; Jones, Sarah K.; Soesbergen, Arnout vanItem Enabling decision-making for agricultural interventions(Report, 2017) Lanzanova, D.; Luedeling, Eike; Whitney, Cory W.Item Estimating water use by crops and other vegetation in the Volta basin using WaterWorld(Report, 2017) Mulligan, Mark; Soesbergen, Arnout vanItem WLE Regional Strategy and Prioritization: Developing a Focal Region Initiative in the Volta and Niger basins(Other, 2013) CGIAR Research Program on Water, Land and EcosystemsItem Report on the main activities undertaken and preliminary findings emerging from research on the CGIAR Targeting Agricultural Innovations and Ecosystem Services in the northern Volta basin (TAI) project(Report, 2016) Boundaogo, M.; Brauman, Kate A.; Chaplin-Kramer, Rebecca; Daré, W.; DeClerck, Fabrice A.J.; Fremier, Alexander K.; Gordon, L.; Katic, P.; Kizito, Fred; Lanzanova, D.; Luedeling, Eike; Johnson, J.; Jones, S.; Malmborg, K.; Mulligan, M.; Rocha, J.The CGIAR Water, Land and Ecosystems research project on Targeting Agricultural Innovations and Ecosystem Services in the northern Volta basin (TAI) is a two year project (2014-2016) led by Bioversity International in collaboration with 11 institutes: CIAT, CIRAD, International Water Management Institute (IWMI), King’s College London (KCL), SNV World Burkina Faso (SNV), Stanford University, Stockholm Resilience Centre (SRC), University of Development Studies Ghana (UDS), University of Minnesota, University of Washington, and the World Agroforestry Institute. We are working with communities across Centre-Est Burkina Faso and Upper-East Ghana to gather empirical data, test research methodologies and co-develop knowledge on solutions to ecosystem service management challenges. Results from the project are still emerging and will continue to do so into 2017 as the team finish analysing the data and writing up their findings. This report presents the main activities accomplished and preliminary headline messages from the first 18 months of the project. Final results from the project will be made available in 2017 on the WLE website.Item Competitive farming strategies and their effect on water provision and profitability among smallholder farms: the case of Muooni Dam site, Kenya(Book Chapter, 2015) Wambua, P.

The GA model considered five objectives: satisfying irrigation water demand, safeguarding water storage for the environment and fisheries, maximizing crop water productivity, protecting the downstream ecosystem against elevated soil salinity and hydromorphic issues, and reducing the unit cost of water. The model constraints are based on hydraulic and storage continuity requirements. The objectives and constraints were combined into a fitness function using a weighting factor and the penalty approaches. The decision variable was water allocation for irrigation demand from reservoir and groundwater. The irrigation water demands around the reservoir were estimated using the Food and Agriculture Organization (FAO) Penman-Monteith method in the water evaluation and planning (WEAP) software. The deterministic GA model was coded using Visual Basic 6 and a new tool for irrigation water management optimization (OPTIWAM) was developed. To validate the applicability of the deterministic model for the operation of coupled reservoir-groundwater systems, the Boura reservoir (in the center-west region of Burkina Faso) and the downstream irrigation area were used as a case study. Results show that the proposed methodology and the developed tool are effective and useful for determining optimal allocation of irrigation water. Furthermore, the methodology and tool can improve water resources management of coupled reservoir-groundwater systems.Item Paysage scientifique, politique et financier de l’Agriculture Intelligente face au Climat en Afrique de l’Ouest(Working Paper, 2015-06-15) Zougmoré, Robert B.; Traoré, Alain S.; Mbodj, YamarLe secteur agricole joue un rôle primordial au sein de la Communauté économique des États d’Afrique de l’Ouest (CEDEAO). En tant que pilier de l’économie, il touche à la vie de la société à plusieurs niveaux, dans la mesure où les économies nationales et les emplois, les revenus et la sécurité alimentaire des populations en dépendent. Les changements et la variabilité climatiques constituent une importante menace pour les agriculteurs de la région qui paient déjà un lourd tribut du fait de la hausse des températures, de la variabilité des précipitations et de l’accroissement de la fréquence des événements extrêmes. La Communauté économique des États d’Afrique de l’Ouest (CEDEAO) a élaboré différents instruments de politique tels que l’ECOWAP et le Plan régional d’investissement agricole (PRIA) y relatif, afin de promouvoir une agriculture moderne et durable fondée sur des exploitations familiales efficaces et efficientes et la promotion d’entreprises agricoles grâce à la participation du secteur privé. Après avoir recensé les besoins exprimés par les États membres, la CEDEAO souhaiterait intégrer un nouveau type d’instruments de politiques publiques dans le PRIA : les instruments d’adaptation de l’agriculture ouest-africaine aux changements climatiques en vue de créer une agriculture intelligente face au climat (AIC) qui met l’accent sur l’adaptation, l’atténuation et les objectifs communs de la sécurité alimentaire et de la nutrition. Le présent livre de synthèse documente et analyse les caractéristiques spécifiques du paysage scientifique, institutionnel, stratégique et de financement de l’AIC en Afrique de l’Ouest. Il contient des informations pertinentes susceptibles d’orienter l’élaboration du Cadre de la CEDEAO pour les interventions, le financement, le suivi et l’évaluation de l’AIC. Il couvre cinq principaux secteurs agricoles : la production végétale, la production animale, la pêche, la foresterie/ agroforesterie et l’eau. Pour chaque secteur, un accent particulier a été mis sur la situation actuelle, les projections climatiques et les impacts socioéconomiques et environnementaux éventuels, les obstacles à l’action et les prochaines étapes suggérées pour l’adaptation et l’atténuation. Des messages et recommandations susceptibles d’être traduits en actes ont été adressés aux parties prenantes de la CEDEAO afin d’encourager la promotion de l’AIC en Afrique de l’Ouest.
