Understanding how water tenure regimes are legally defined, implemented and protected is fundamental to sustainable and equitable management of the resources and essential to achieving their responsible governance. Increasing water demand poses a significant challenge for all FAO Members in terms of water allocation and the governance of water tenure in the context of food security. COAG at its 28th session recommended FAO to undertake an assessment of existing water tenure arrangements and initiate a Global Dialogue on Water Tenure. In response, FAO and partners have developed innovative water tenure assessment methodologies to equip stakeholders with crucial data to inform policy decisions and legislative reform. Furthermore, FAO organizes the Global Dialogue on Water Tenure with the aim of identifying principles on the responsible governance of water tenure in an inclusive consultative process with Member States, civil society, academia and international organizations.
