TOTAL WEALTH OF LIFE
ON EARTH……
PLANTS+ANIMALS+MICROORGANISMS.
GENES – GENETIC DIVERSITY
SPECIES – SPECIES DIVERSITY
ECOSYSTEMS - ECOSYSTEM DIVERSITY
ENCASHING DIVERSITY…..
FUTURE POWERFUL TECHNOLOGIES GENE BASED.
BIOTECHNOLOGICAL WORLD – BIODIVERSITY IS BASE
DEVELOPED COUNTRIES TECHNOLOGY + ECONOMY.
WANT EASY, CHEAP ACCESS TO BIODIVERSITY
RESOURCES AND RELATED KNOWLEDGE CONCENTRATED IN TROPICAL DEVELOPING COUNTRIES.
DEVELOPING COUNTRIES RIGHTS + RETURNS.
THE BIODIVERSITY DIVIDE…
INTERNATIONAL EFFORTS…..
CONVENTION ON BIODIVERSITY (CBD) – 1992
More than 170 signatories
Objectives: Biodiversity conservation, Sustainable
exploitation & Equitable sharing of profits.
2002 December – Biodiversity Act of India
SOVEREIGN RIGHTTS OVER BIODIVERSITY ESTABLISHED
Biodiversity management responsibilities -
National B.D. Authority – National Authority
State B. D. Boards – at State levels &
Local B. D. Management committees – at Local body levels
BIODIVERSITY LOSS….
•20% in next 30 years?
•50% by end of 21st
century ?
REASONS…..
•Natural extinction
•Habitat destruction
•Overexploitation …..
