Biodiversity as a natural capital: The findings of the Millennium Ecosystem Assessment (MEA)

1. Biodiversity as a natural capital: The findings of the Millennium Ecosystem Assessment (MEA) Dr. V.B. Mathur Dean, Faculty of Wildlife Sciences Wildlife Institute of India vbm@wii.gov.in Pre-meeting training course IAIA ’08 Perth, Australia

2. What is Biodiversity? "A definition of biodiversity that is altogether simple, comprehensive, and fully operational ... is unlikely to be found." …Noss, 1990

3. What is Biodiversity? "Biological diversity is the variety and variability among living organisms and the ecological complexes in which they occur" …U.S. Congress Office of Technology Assessment, "Technologies to Maintain Biological Diversity," 1987

4. What is Biodiversity? "Natural diversity is synonymous with biological diversity... To the scientist, natural diversity has a variety of meanings. These include: 1) the number of different native species and individuals in a habitat or geographical area; 2) the variety of different habitats within an area; 3) the variety of interactions that occur between different species in a habitat; and 4) the range of genetic variation among individuals within a species." … Jones and Stokes Associates' "Sliding Toward Extinction: The State of California's Natural Heritage," 1987

5. What is Biodiversity? "Biological diversity, simply stated, is the diversity of life... biological diversity means the full range of variety and variability within and among living organisms and the ecological complexes in which they occur, and encompasses ecosystem or community diversity, species diversity, and genetic diversity." …D.B. Jensen, M. Torn, and J. Harte, "In Our Own Hands: A Strategy for Conserving Biological Diversity in California," 1990

8. What drives environmental change? • This question was addressed by 1360 scientists from 95 countries in the form of Millennium Ecosystem Assessment (MEA) project for 5 years (2000-2005).

Global Balance Sheet Enhanced Degraded Mixed • Crops • Livestock • Aquaculture • Carbon sequestration • Capture fisheries • Wild foods • Wood fuel • Genetic resources • Biochemicals • Fresh Water • Air quality regulation • Regional & local climate regulation • Erosion regulation • Water purification • Pest regulation • Pollination • Natural Hazard regulation • Spiritual & religious • Aesthetic values • Timber • Fiber • Water regulation • Disease regulation • Recreation & ecotourism Bottom Line: 60% of Ecosystem Services are Degraded

23. What have we achieved globally in conservation? • Put together a global framework- Convention on Biological Diversity (CBD, 1992). • Ratified by 192 countries. • CBD tenets: • Conserve biodiversity • Use sustainably • Share equitably • An impressive network of Protected Areas (National Parks, Wildlife Sanctuaries, Nature Reserves etc).

24. What have we failed to do globally in conservation? • Get the CBD to function effectively. • Value conservation benefits adequately. • Move the pro-people agenda. • Garner adequate political support for mainstreaming conservation.

25. What is changing…? • Global pressures and demands. • People’s pressures on resources. • Priority for conservation (Development v/s Conservation). • If 90’s was the decade for conservation; 2000s indicates missed opportunities.

26. The Way Forward…… • Mainstreaming conservation in development planning. • More policy and legal reforms to address resource sharing and equity issues. • Enhance professionalism of the range of stakeholders though capacity building.
