The document summarizes the Nexus Regional Dialogues Programme, which aims to promote the water-energy-food security nexus approach across five regions. It highlights the interdependencies between these sectors and supports sustainable resource management. The program is implemented through four pillars: knowledge exchange, an online resource platform, capacity building, and pilot projects. Regional dialogues have occurred in MENA, Niger Basin, Latin America, Southern Africa and Central Asia. The dialogues developed recommendations, guidelines and action plans. Lessons indicate a need for demand-driven and comparable approaches while aligning with development goals. Phase II will focus on enabling concrete project impacts.
