Additional resources for specific activities under the work-programme have been raised by the ISRBC Secretariat from the European Commission and the international donor community. In this regard, a set of activities for the rehabilitation of the Sava River waterway and the development of navigation, a priority issue, have been implemented, and relevant work is on-going. While navigation is important for the economic development in the basin, the interventions in the watercourse for rehabilitation of navigation and the construction of related hydro-engineering structures may become additional pressure factors. The Sava River Basin Analysis Report was developed as a first step towards this direction.
