Globally, mangrove forests represents only 0.7% of world’s tropical forested area but are highly threatened due to susceptibility to climate change, sea level rise, and increasing pressures from human population growth in coastal regions. Our study was carried out in the Bhitarkanika Conservation Area (BCA), the second-largest mangrove area in eastern India. We assessed total ecosystem carbon (C) stocks at four land use types representing varying degree of disturbances. Ranked in order of increasing impacts, these sites included dense mangrove forests, scrub mangroves, restored/planted mangroves, and abandoned aquaculture ponds. These impacts include both natural and/or anthropo- genic disturbances causing stress, degradation, and destruction of mangroves. Mean vegeta- tion C stocks (including both above- and belowground pools; mean ± standard error) in aquaculture, planted, scrub, and dense mangroves were 0, 7 ± 4, 65 ± 11 and 100 ± 11 Mg C/ha, respectively.

Journal of Applied and Natural Science, 12(4):710 - 720. https://doi.org/10.31018/jans.v12i4.2412 Abstract Biodiversity is not equally distributed across the world. It depends on the type of various habitats and food availability. In these habitats, wetlands play an import role to increase the biodiversity of the particular area. Many studies have focused on various habitats to conserve biodiversity. However, the wetland studies are very few due to the lack of information on their distribution and importance. The present review focusses on the wetland status and their importance in India. India has vibrant and diverse wetland ecosystems that support immense biodiversity. The wetlands are unique habitats which provide ecological, social and economic values. However, rapid urbanization, industrialization and uncontrolled agricultural practices have pressurized to shrink the wetlands in India.

  • Chapter-1 Bhitarkanika Mangroves Ecosystem- an Overview
    Chapter-1 Bhitarkanika Mangroves Ecosystem- An Overview The Indian coastline of about 5,700 km long can be divided into the east and west coasts and island chains. The east coast covers the maritime states like Tamil Nadu, Andhra Pradesh, Orissa, West Bengal and Andaman-Nicobar Islands. The West coast extends from Kerala, Karnataka, Goa, Maharashtra, Gujarat and also includes the coral atolls of Lakshadweep Islands. The total mangrove area along the Indian coast is estimated to be approximately 700,000 ha. The mangroves along the east coast of India is more (80%) than that of west coast (20%) because the terrain of the east coast has a gradual slope as plains compared with the steep gradient along the west coast. Map of India’s Ecologically Important Areas (EIA)showing Bhitarkanika among others [Source: iomenvis.nic.in/Bhaitharkanika.htm] Geographic Location of Orissa coast: Orissa coast is mainly depositional in nature, forme by the Mahanadi and the Brahmani- Baitarani deltas. The State has a long coastline (480 kms), lagoons and offshore islands on the eastern part along the Bay of Bengal, while on the western part it has large areas of hilly 1 forests. The coastal plains of the State extend from Subarnarekha River in the north to the Rushikulya in the south and are narrow in the north. Mahanadi and Subarnarekha are the major estuaries, while Rushikulya, Bahuda, Devi, Balijhori, Ghalia, Kharnasi, Jambu,etc are the minor estuaries. Chilka Lake is the largest brackish water lagoon in Asia and stretches over an area of 1100km. Bhitarkanika is the second largest mangrove ecosystem of India, next to Sundarbans mangroves.
