Coastal and Marine Protected Areas
Coastal and Marine Protected Areas
Purpose and Significance
- India’s coastal and marine ecosystems are biologically diverse and ecologically sensitive. The establishment of Coastal and Marine Protected Areas (MPAs) is aimed at conserving these ecosystems in their natural and undisturbed condition. These areas help protect critical habitats such as coral reefs, mangroves, lagoons, estuaries, and seagrass beds, which serve as essential breeding and feeding grounds for a wide variety of marine species. By ensuring the health of these ecosystems, MPAs also support sustainable fish production and contribute to the overall productivity of the marine environment.
Definition of Marine Protected Areas
- According to the International Union for Conservation of Nature (IUCN), a Marine Protected Area is defined as any area of intertidal or subtidal terrain, along with the overlying water and associated flora, fauna, historical, and cultural features, which has been legally or otherwise effectively protected to conserve all or part of the enclosed environment. This definition emphasizes both ecological and cultural significance and highlights the importance of preserving entire marine systems, not just individual species.
Coastal Biodiversity Hotspots in India
- India’s marine productivity is concentrated in small but biologically rich regions along the coastline. These include coral reefs, estuaries, mangrove forests, lagoons, and seagrass beds. Such ecosystems are not only vital for biodiversity conservation but also act as buffers against coastal erosion, serve as carbon sinks, and support the livelihoods of millions of coastal communities.
Classification of Marine Protected Areas in India
- Marine Protected Areas in India are classified into several categories based on the ecological features they represent. The first category includes National Parks and Wildlife Sanctuaries that are entirely located in intertidal or subtidal zones, covering habitats such as mangroves, coral reefs, seagrass and algal beds, estuaries, creeks, and lagoons. The second category consists of islands that possess both marine and terrestrial components, with a significant portion of their ecology embedded in marine ecosystems. The third category is further divided into two types: Category IIIA includes sandy beaches that lie beyond the intertidal line but interact with seawater occasionally, while Category IIIB includes evergreen or semi-evergreen forests found on islands that play an ecological role in marine-terrestrial connectivity.
Legal Status and Coverage
- At present, India has notified 33 Marine Protected Areas under the Wildlife (Protection) Act, 1972. These MPAs include some of the most ecologically diverse coastal habitats in the country. In practice, some of these areas are managed together. For example, the Marine National Park and Marine Sanctuary in the Gulf of Kutch form a single unit, and similarly, the Bhitarkanika National Park and Bhitarkanika Wildlife Sanctuary in Odisha are treated as one MPA. Accounting for such combined units, the total number of recognized MPAs in India stands at 31.
