In a development that may ring alarm bells for each environmentalists and policy manufacturers, the flowering tree forest cowl within the Indian Sunderbans has been depleting alarmingly over the past few decades.
It has been found that from 1986 to 2012, 124.418 sq. km. flowering tree forest cowl has been lost.
The total forest cowl of the Indian Sunderbans was concerning a pair of,246.839 sq. kilometer in year 1986., that bit by bit declined by a pair of,201.41 sq. km. in 1996, then all the way down to 2168.914 sq kilometer in 2001 and to 2122.421 sq kilometer in 2012. The loss within the flowering tree forest within the Indian Sunderbans is concerning five.5 %.
“The continuation of this method in response to global climate change and water level rise poses a heavy threat to the carbon sequestration potential and alternative scheme services of this flowering tree forest in future,” .
The paper additionally notes that the mean water level rise at the Sagar Island Station, measured from 1985 onward until 2010, shows an increase by a pair of.6-4 millimeter a year, which may be thought-about a driving issue for coastal erosion, coastal flooding, and a rise within the range of recurrent event creeks.
The publication highlights a statistic of the erosion of a minimum of eighteen flowering tree wooded islands of the Indian Sunderbans from 1986 to 2012. as an example, the loss in flowering tree cowl at Gosaba has been concerning 2 hundredth, down from 517.47 sq kilometer in 1986 to five06.691 sq kilometer in 2012.
In Dulibhasani West, the loss of flowering tree cowl has been concerning nine.7% — from a hundred and eighty.03 sq. km. in 1986 to 163.475 sq. km. in 2012. The flowering tree forest cowl of Dalhousie, another island, has depleted by 16 PF, from 76.606 sq. km. in 1986 to sixty four.241 in 2012. Bhangaduni has one in every of the best erosion levels of flowering tree forest land, from 40.4 sq. km. in 1986 to twenty four.9 sq kilometer in 2012, taking the loss to over thirty seventh.
Jambudwip, one in every of the tiniest unpeopled islands at the mouth of the ocean, additionally has reduced forest cowl from half-dozen.095 sq. km. in 1986 to 5.003 sq. km. in 2012, or concerning 100%.
Other islands like Sajnekhali North, Matla and Bulchery have additionally suffered vital flowering tree loss.
Professor Hazra, UN agency heads the varsity of Oceanographic Studies, Jadavpur University, explained however global climate change and water level rise has contributed to the development of losing land, together with flowering tree forests within the Sundarbans, within the last a part of the twenty first century.
“This is as a result of there’s less H2O flow and sediment offer within the western (Indian) a part of the delta, therefore we’ve starvation of sediment and also the rate of water level rise is over sediment offer. thus we tend to ar losing land, together with flowering tree forest,” he told The Hindu.
According to faculty member Hazra, the japanese (Bangladesh) aspect of the delta is gaining land attributable to the massive
