Hydropower generation (HPG) represents the largest renewable electricity source with multiple purpose functions worldwide especially in WestAfrica (WA) where it contributes significantly to the energy security. However, this source is sensitive to climate change and projected HPG areassociated with uncertainties. The magnitude and the sign of projected change of HPG vary according to the river basin and country. Part ofuncertainties in the future of HPG in WA is associated with the lack of observations data which limit the calibration of models and the simulation ofhydrological dynamics and also, with uncertainties associated with climate projections used to force hydrological and water resources models. Landuse changes associated with socioeconomic development are rarely taken into account while they are crucial, especially over multi-purpose dams. Itbecomes then difficult for dam managers and local authorities to make decisions or to plan under these uncertainties in the aim to engage in a climateresilient pathway. This project aims to build communities of practice with HPG stakeholders (dam managers, local policy makers, representative ofcivil society) to address the challenges, synergies and trade-off in the climate land energy water nexus in WA for a sustainable management andplanning of HPG under a context of climate and land use changes. This will be achieved through two elicitation and participatory workshops with stakeholders, two training sessions to Early Career Researchers of the project on "Random Forest, use of downscaled climate data" (top-down methods) and "Decision Scaling" (bottom-up method) which will be implemented with local stakeholders in each of the 4 major dams in Ghana, Senegal, Burkina Faso and Ivory Coast. During the implementation, the project will foster sharing and common learning between the 4 case studies from results of comparative study of these 3 practices. The project targets the nexus between SDG 13 (climate), 6 (water) and 7 (energy) with positive effects on SDG 15 (land) and 17 (partnership) for sustainable HPG

水电生成（HPG）代表了全球具有多个目的功能的最大可再生电源，尤其是在Westafrica（WA），在那里它对能源安全产生了重大贡献。但是，该来源对气候变化敏感，并预测与不确定性相关的HPG区域。根据河流域和国家，HPG变化的规模和迹象有所不同。 WA中HPG未来的一部分与缺乏观察数据有关，这些数据限制了模型的校准和水文动力学的模拟，并且与用于强迫水文和水资源模型的气候预测相关的不确定性。与社会经济发展相关的土地废物的变化很少在至关重要的同时，尤其是多功能大坝。然后，ITBECOMES很难让大坝经理和地方当局做出决定或根据这些不确定性进行计划，以进行气候途径。该项目旨在与HPG利益相关者（DAM经理，地方决策者，Ofcivil Society代表）建立实践社区，以应对西澳气候土地能水Nexus在气候和土地使用变化下的可持续管理和规划HPG的挑战，协同和权衡。这将通过两次启发和参与性讲习班与利益相关者，对“随机森林，使用降低的气候数据使用”（自上而下的方法）和“决策缩放方法”（自下而上的方法）进行的两个培训，将与田纳西州4个大型阶层的本地利益相关者进行实施，这将实现。在实施过程中，该项目将从这三种实践的比较研究结果中促进4个案例研究之间的共享和共同学习。该项目针对可持续HPG的SDG 13（气候），6（水）和7（能源）之间的联系，对可持续HPG的SDG 15（土地）和17（合作伙伴关系）的纽带。
