Internationally, a number of recent negotiation successes have been reported from different parts of the world. It is generally easier to negotiate treaties on the navigable uses of rivers, since these do not require water allocation or use considerations.
This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends promoting navigational safety by appropriate and adequate charting of coasts and ship-routing.
