Considering the degree of threat to biodiversity around the world and the vital importance of biodiversity for living beings of which mankind is a major part, there is an urgent need to conserve biodiversity in the world. Further, we should be concerned about saving biodiversity because of the benefits it provides us – biological resources and ecosystem services, and the social and aesthetic benefits
In-situ or on-site conservation refers to the conservation of species within their natural habitats. This is the most viable way of biodiversity conservation. It is the conservation of genetic resources through their maintenance within the environment in which they occur.
Examples − National Parks, Wild Life sanctuaries, Biosphere Reserves, Gene Sanctuaries
Ex-situ conservation means the conservation of components of biological diversity outside their natural habitats. In this method, threatened or endangered species of animals and plants are taken out of their natural habitat and placed in special settings where they can be protected and provided with natural growth.
In ex-situ conservation methods, the plants and animals taken away from their habitats are taken care of in an artificially created environment.
Examples − Captive Breeding, Gene Banks, Seed Banks, Zoos, Botanical gardens, Aquaria, In vitro fertilization, Cryopreservation, Tissue Culture.
National Biodiversity Act
National Biodiversity Act in India draws from the objectives of Convention of Biodiversity (CBD). It aims at conservation of biodiversity, sustainable use and equitable sharing of the benefits of such use.
- To achieve its objectives, it has put in place a three-tier institutional structure such as −
- National Biodiversity Authority based in Chennai
- State Biodiversity Board (SBBs) in every state
- Biodiversity Management Committee (BMCs) at Panchayat/Municipality levels
- The Ministry of Environment and Forestry (MoEF&CC) is the nodal agency.
Wildlife Protection Act, 1972
