The majority of the most important river systems in the world are shared by two or more States. Almost 90 % of the world's population lives in shared river basins. One of the strategic priorities that DDP promoted as part of its efforts to improve decision-making on dams referred to sharing rivers for peace, security and sustainable development. At the same time that the project focused on the strengthening of national policy/legal/regulatory frameworks, DDP aimed at promoting improved and harmonized approaches by States sharing water resources through facilitating dialogue on dams and development at regional and river basin level.
The involvement of the corresponding river basin organizations, when it existed, was fundamental for applying the recommendations into effective policy and regulation at regional level supported by consistent national regulations
of the member States.
