21. The ECE region focuses on implementation of the Decade primarily through the lens of the Convention on the Protection and Use of Transboundary Watercourses and International Lakes, which has been both an official mechanism through which policies are established at the regional level and an instrument critical to the implementation, of those policies on the ground by the parties to the Convention. Application of the Convention has been successful in promoting more than just transboundary river basin cooperation. It has been effective in furthering cooperation among countries through project implementation and exchange of knowledge and experiences. It has also fostered national-level policy development through national policy dialogues, which has improved water resources management in the region, and enabled the goals of the Decade to be met. By making climate change adaptation activities and work related to the water-food-energy-ecosystem nexus a key focus, the Convention has promoted the goals and principles of the Decade.
