1. Ecosystem-based River Basin Management (EcoBasin) and Data Need Takehiro NAKAMURA Programme Officer (Water) Division of Environmental Policy Implementation United Nations Environment Programme (UNEP)

2. An INTEGRATED approach Integrated River Basin Management ------ to manage relevant factors in the basins in order to achieve multiple objectives for resource use and protection of the aquatic environment. It is also an approach, which essentially takes a cross- sectoral and interdisciplinary approach to achieve institutional co-ordination and co- operation.

3. UNEPs approach Approaches to monitoring, assessment and management Integrated Coastal Area and River Basin Management (ICARM) (www1.unep.org/icarm) Ecosystem-based approach (follow-up to Wetlands and Integrated River Basin Management)

5. Different types of Ecosystems involved in River Basins Forest ecosystem Agricultural ecosystem Aquatic/Wetland ecosystem ----> examples of ecosystem functions (WRI classification)

7. Ecosystem-based River Basin Management Reduce ecosystem vulnerability and maximise ecosystem resilience based on the identified ecosystem functions to address environmental and resource issues

11. Vulnerability Index (Indicators) Indicating ecosystem vulnerability and resilience Initiated for flood vulnerability (China, Vietnam, Bangladesh, Iran(?), Central Africa(?))

21. Example of indicators in the Yangtze River Basin (Ecosystem functions focussing on flood magnitude and frequency)

32. Indicator: Pesticides

33. Indicator: Nature protected areas

35. Ecosystem-based River Basin Management (EcoBasin) - Started with flood impact mitigation - Extension to cover other ecosystem functions - Yangtze River case - Detailed assessment for the Lake Dongting basin (county - 10km vs. 10km) - More indicators on Ecosystem Resilience
