Mangrove Forest Cover Changes in Indian Sundarban (1986-2012) Using Remote Sensing and GIS, a publication by the School of Oceanographic Studies, Jadavpur University, reveals that from 1986 to 2012, 124.418 sq. km. mangrove forest cover has been lost.
About the Study
- In a development, for both environmentalists and policy makers, the mangrove forest cover in the Indian Sunderbans has been depleting alarmingly over the past few decades.
- The loss in the mangrove forest in the Indian Sunderbans is about 5.5 %.
- The continuation of this process in response to climate change and sea level rise poses a serious threat to the carbon sequestration potential and other ecosystem services of this mangrove forest in future.
- The mean sea level rise at the Sagar Island Station, measured from 1985 onward till 2010, shows a rise by 2.6-4 mm a year, which can be considered a driving factor for coastal erosion, coastal flooding, and an increase in the number of tidal creeks.
- The erosion of at least 18 mangrove forested islands of the Indian Sunderbans from 1986 to 2012.
