Targeting Agricultural Innovations and Ecosystem Service Management in the northern Volta basin Authors: Sarah Jones1,2,*, William’s Daré3, Fabrice DeClerck1, Martine Antona3, Mansour Boundaogo4, Kate Brauman5, Elin Enfors6, Becky Chaplin-Kramer7, Alex Fremier8, Line Gordon6, Raymond Kasei9, Pamela Katic10, Fred Kizito11, 12Denis Lanzanova, Eike Luedeling12, Katja Malmborg6, Mark Mulligan2, Aline Ortega8, David Smedley2  Highlights • Combining field work, remote sensing and modelling is enabling us to understand intra-annual and inter-annual changes in ecosystem services supplied and used in small reservoir systems Results • Over 10 case study communities engaged in TAI project research so far including: Binaba, Nafkuliga, Tanga,  Tonde, Widenaba, Zongoyire (Ghana), Bidiga, Boussouma, Ladwenda, Ouéguédo, Zidre (Burkina Faso) • Reservoirs supply water provisioning and regulation services that underpin fish, crop and livestock production • Ecosystem services and their uses vary between reservoirs and between seasons • Landsat imagery can be used to detect intra-annual and inter-annual trends in reservoir water supply Pictures July 2016 Purpose • Characterise ecosystem services associated with small reservoir systems • Identify potential scenarios for improved management of these ecosystem services using participatory processes • Model the effect of these changes on ecosystem service and food supply, delivery and livelihood impacts • Work with local and regional stakeholders to identify and test benefit sharing mechanisms Method About the CGIAR RESEARCH PROGRAM ON WATER, LAND AND ECOSYSTEMS The CGIAR Research Program on Water, Land and Ecosystems in the Volta and Niger Basins (WLE Volta-Niger) is a research-for-development initiative that seeks to restore and bolster opportunities for increased agricultural productivity through key ecosystem services, especially in the resource poor areas in the region.    The CGIAR Research Program on Water, Land and Ecosystems (WLE) is a global research program that promotes a new approach to sustainable agricultural intensification in which a healthy functioning ecosystem is seen as a prerequisite to agricultural development, resilience of food systems and human well-being. This program is led by the International Water Management Institute (IWMI), a member of the CGIAR Consortium, and is supported by CGIAR, a global research partnership for a food-secure future.
