The United Nations Convention of 1997 allows the conclusion of an agreement with respect to an entire international watercourse or any part thereof or a particular project, programme or use except in so far as the agreement “adversely affects, to a significant extent”, the use by one or more other watercourse States of the waters of the watercourse, without their express consent. Existing joint bodies are endeavouring to establish cooperation with States that are not participants of agreements and eventually to have all riparian States as Parties to the relevant agreement. In 1994, for its share of the lake basin, the Central African Republic was admitted as the fifth member of the Commission.
