Economic assessment mangrove ecosystems’ goods services of India
Keywords:
mangrove, economic valuation, benefit transfer, IndiaAbstract
Mangroves are a group of trees and shrubs that live in the coastal intertidal zone. Mangroves have been distributed in low-energy, tidal shorelines between latitudes in tropical and subtropical areas. Mangroves are important productive ecosystems in coastal areas. Mangrove ecosystems are rich in biodiversity and provide a wide range of goods and services to human communities living in coastal areas including wood and non-wood forest products, fisheries, medicines, tannins, apiculture, wildlife resources, fishery, recreation, ecotourism, bio-filtration, nursery grounds, coastal protection, and carbon sequestration. Mangroves are bio shields of the coast and protect people from disasters like tsunamis, and cyclones. Mangroves support shoreline protection, sediment accretion, and, other functions. Mangrove cover in coastal areas of India is 559098.62 ha. They have been discontinuously distributed in 42859 patches of the coastal areas. India's coastal States and UTs are distributed with mangrove ecosystems except the UT of Lakshadweep. Benefits from mangroves are often ignored by industry and local inhabitants since the values of goods and services and their equivalent economic benefits are derived from the mangroves of India. This study aims to analyse various benefits of mangroves and estimate their equivalent economic benefit to inform the conservation benefits of mangroves. This study has followed the Millennium Ecosystem Assessment framework. The average total economic benefit of mangroves' goods and services is the equivalent economic values of India’s mangroves range between Rs. 92662/-/ha/yr., = US$1985.17 ha/yr (minimum) and Rs. 3361144 = US$72008.47/-/ha/yr. (maximum) with an average total economic benefit of Rs. 958766/ha-/yr = US$ 20540.41/ha-/yr. The mangrove ecosystems of India are contributing equivalent economic benefit of Rs. 53604 crore Rs./yr., = US$1148.40 Rs./yr (Average) to the welfare of coastal communities. The ecosystem value shall support policy decisions and awareness creation on conservation benefits and sustainable utilisation of goods and services of the mangrove ecosystem.
