Second international meeting of the members of the CACCAO project. Initiated in 2020, and supported by IRSTV, the Consortium for Adaptation to Climate Change in West Africa (CACCAO) is a project that aims to create a multi-stakeholder research framework (academic, operational) based on impact analysis in order to propose solutions adapted to West African contexts (recommendations, knowledge sharing, data portal, digitalization, etc.). The general objective of the seminar is to consolidate the consortium by working to structure reflections around an interdisciplinary approach and a better knowledge of nature-based solutions. More specifically, this meeting will be an opportunity to advance the consortium's scientific project and take stock of the work carried out within its various themes. Finally, it will be a question of establishing a timetable for upcoming activities.
