Since 1991, UNDP-GEF’s International Waters Programme has been supporting over one hundred countries that share some of the world’s largest and most important aquatic ecosystems to work cooperatively in addressing the agreed priority environmental and water resource concerns facing such waterbodies.

'International Waters – Delivering Results' is the fifth in a series of knowledge publications prepared by the UNDP-supported and GEF-financed International Waters programme that document and highlight key results and achievements at the project and portfolio level, comprising four ‘signature’ programme areas:  Large Marine Ecosystems; Lakes, Rivers and Aquifers; Integrated Water Resources and Coastal Area Management; and Global Programmes. The portfolio continues to make progress in sustaining the world’s most significant shared water systems for the billions of people who depend on these ecosystems for their livelihoods and security.
