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

水力发电（HPG）是全球最大的具有多种用途的可再生电力来源，特别是在西非（WA），它为能源安全做出了重大贡献。然而，该来源对气候变化敏感，预计 HPG 存在不确定性。 HPG 预计变化的幅度和迹象因流域和国家而异。西澳 HPG 未来的部分不确定性与缺乏观测数据有关，这限制了模型的校准和水文动力学的模拟，而且还与用于强制水文和水资源模型的气候预测相关的不确定性有关。与社会经济发展相关的土地利用变化虽然至关重要，但很少被考虑在内，特别是在多功能水坝上。在这些不确定性的情况下，大坝管理者和地方当局很难做出决策或规划，以走上一条适应气候变化的道路。该项目旨在与 HPG 利益相关者（大坝管理者、当地政策制定者、民间社会代表）建立实践社区，以应对西澳气候土地能源水关系中的挑战、协同作用和权衡，从而实现 HPG 的可持续管理和规划。气候和土地利用变化的背景。这将通过与利益相关者举办的两次启发和参与式研讨会、为该项目的早期职业研究人员举办两次关于“随机森林，使用缩小规模的气候数据”（自上而下的方法）和“决策规模”（自下而上的方法）的培训课程来实现）将与加纳、塞内加尔、布基纳法索和科特迪瓦 4 个主要水坝的当地利益相关者一起实施。在实施过程中，该项目将通过这 3 种实践的比较研究结果，促进 4 个案例研究之间的共享和共同学习。该项目旨在实现可持续发展目标 13（气候）、6（水）和 7（能源）之间的联系，并对可持续 HPG 的可持续发展目标 15（土地）和 17（伙伴关系）产生积极影响
