the International Research Network RHYMA-CES funded by the French Institute of Research for Development (IRD). It follows previous editions held in Hammamet (2015), Dakar (2016), Algiers (2018), and Cotonou (2021), which helped establish an active pan-African scientific community focused on African rivers and hydrological regimes. The conference is supported by the UNESCO FRIEND-Water program and the International Association of Hydrological Sciences (IAHS), thereby enhancing the international visibility of African research.
