Objectives: To codify international law regarding non-navigational uses of international watercourses and encourage its development. Summary of provisions: This Convention is a framework Convention adopted with a view to ensuring the utilisation, development, conservation, management and protection of international watercourse and the promotion of their optimal and sustainable utilisation for present and future generations. Part I defines terms and sets the framework for the conclusion of watercourse agreements between watercourse States. Part II provides the general principles that are to guide the Parties in their utilisation of watercourses. Are included equitable and reasonable utilisation and participation, obligation not to cause significant harm to other watercourse States, obligation to co-operate, and regular exchange of readily available data and information on the conditions of the watercourse. Part III sets out a notification procedure for planned measures which have possible adverse effects on other watercourse States, and Part IV deals with, inter alia, protection and preservation of ecosystems, prevention, reduction and control of pollution, introduction of alien or new species, and protection and preservation of the marine environment. Part V further deals with harmful conditions and emergency situations, and Part VI with international watercourses and installations in time of armed conflict, data vital to national defence or security, non discrimination, and settlement of disputes.
