Climate change cost upon ecosystem services in the Sundarban mangrove forest in Bangladesh
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 11, Issue 1
Abstract
The Sundarban forest, known as the mangrove protection region by the UNESCO for numerous world endangered species, is located in the southwest of Bangladesh that lies between the delta of the Ganges, Brahmaputra and Meghna rivers. It is the habitat of Royal Bengal tiger (Panthera tigris) which is a world largest endangered mammal species and can only be adapted for surviving in the mangrove forests. Also, other endangered species including Heritiera fomes, Excoecaria agallocha, and Ceriops decandra are largely distributed in the mangrove forest but the rise of mean sea level in 2100 will resulted in 77% decrease of their distributions, so the conservation of the region is so imminent. Thus, ecological service value of Sundarban mangrove with US $ 402 million in 2001 will be reduced by 45% in 2100. In this study, such potential impacts of ecological service on climate change were analyzed on the Sundarban mangrove forest in Bangladesh. The impacts of climate change on the Sundarban mangrove were projected considering various primary resources that are being exploited in the ecosystem and ecological physiography of the mangrove. Secondary information on forest dependent livelihoods degrading condition, reducing ecosystem services and degrading physiographic characteristics of Sundarban mangrove forest were collected and projected the apparent impacts. Further studies should be quantified about long-term impacts of climate change on all the ecosystem services and explore on the potential loss of biodiversity and opportunities in the future for better conservation.
