This publication is the main output of the "Transboundary Water Cooperation in the Newly Independent States" project. It aims to define the status, trends and further needs with regard to transboundary water cooperation in the Newly Independent States (NIS), and between NIS and their neighbours. The analysis and recommendations will provide a basis for future actions and projects for the development of cooperation in the NIS on transboundary waters, in particular within the work programme of the UNECE Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) and the Strategic Partnership on Water for Sustainable Development.
