Under the ENVSEC Initiative, the OSCE supported a project on water resources management of the Sava River Basin. The project concentrated on the development of a network of local actors to facilitate the process of water management between Slovenia, Croatia, Bosnia and Herzegovina, and Serbia. It was aimed at supporting the International Framework Agreement on the Sava River Basin of 2004 and its governing institutions.

The Agreement had a wide scope, covering issues including maintenance of water quality and quantity, flood protection, utilization with the purpose of energy production, and potential for the tourism industry. On the basis of the Agreement, the International Sava River Basin Commission was established in 2005. The OSCE project:

• promoted capacity-building of the Commission, organising national workshops and meetings for water suppliers and local, regional and national authorities;
• attracted the public sector into the water management sector by involving NGOs in these workshops;
• promoted effective functioning of the Commission through assistance in drafting numerous working plans.

The OSCE also emphasised an integrated water management approach and promotion of the principles of international water law in the activities of the Commission.

The project started in 2004 with a budget of 70,000 euros.
