The workshop focused on transboundary water resources management in southeastern Europe, highlighting the need for enhanced cooperation and integrated management of shared water resources. Key challenges include political instability, economic reforms, and stakeholder engagement, with ongoing initiatives like the UNECE Water Convention supporting collaborative efforts. GWP-Med and GWP-CEE are actively involved in projects aimed at promoting joint management of critical water basins, such as the Mesta/Nestos and Drin rivers.
