The purpose of this project is to improve the quality of planning and investment in the 3S region by undertaking activities in three consecutive "streams": i) nexus assessment; ii) capacity building for regional decision-making processes; iii) regional dialogues. IWMIs contribution to this study is primarily to support the nexus assessment. Based largely on literature review and guided by a Technical Advisory Group (TAG), IWMI will contribute to understanding of the current condition in the basin, the principal drivers of change and the likely trade-offs associated with different development options. IWMI will conduct sector assessment, economic assessment and livelihoods assessment each of which will comprise a baseline analyses to understand the current situation and an assessment of possible future trends based on development plans and drivers of change. To the extent possible all data/information will be disaggregated by basin and country.
