Sunderbans absorb over 4 cr tonnes of CO2
Protecting the world from the adverse [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] affects of climate change, the Sunderbans forests play a crucial ecological role by acting as a carbon sink and absorbing more than four crore tonnes of carbon dioxide from the atmosphere, according to a recent study.
Having 2118 sq km of total mangrove forest cover, the Indian Sunderbans have soaked in 4.15 crore tonnes of carbon dioxide, valued at around $79 billion in the international market, researchers from the University of Calcutta said.
trees act as a natural tank for carbon dioxide storage. They absorb [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] carbon for their own needs, which is a boon for us. The more such biomass we have on earth, the more CO2 will be pulled from the atmosphere. This will ultimately result in controlling the rise of atmospheric temperature and the subsequent climate change, Prof Abhijit Mitra, who led the research, told PTI.
This process of removing carbon from the atmosphere and depositing it in a reservoir is known as carbon sequestration.
As a primary [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] greenhouse gas, large scale CO2 emission is responsible for global warming as it leads to a rise in sea levels and temperature, adversely affecting agriculture, fishery and human health.
With funding from the Union Ministry of Earth Science and the state forest department, the two year long study of [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] the carbon sequestration efficiency of the mangroves was done by the varsity marine science department.
Out of the total amount of carbon tied up in earthbound forms, an estimated 90 per cent is contained in the world forests. For each cubic [عزيزي الزائر يتوجب عليك التسجيل لمشاهدة الرابط للتسجيل اضغط هنا] foot of merchantable wood produced in a tree, it has been estimated that about 15 kg of carbon is stored in total tree biomass.
To evaluate carbon stocks in the above ground biomass (AGB) of three dominant mangrove species ( apetala alba and agallocha in the Sunderbans, carbon content in stem, branch and leaf biomass was estimated using laser beams by the team of ecologists.
The estimates done in the study, however, exclude the below ground biomass found under the soil.
Atanu Raha, the state principal chief conservator of forests, pointed out that the results are positive as there has been no degradation of forest cover in the Sunderbans.
the core forest area, there has been no degradation due to human intervention. Only few forest trees have been lost due to natural reasons beyond our control, he said.
The unique biological productivity, taxonomic diversity and aesthetic beauty of the Indian Sunderbans has been recognised with the crowns of World Heritage Site and Biosphere Reserve in 1987 and 1989 respectively by the UNESCO.
The study also found that the central part of the Sunderbans is a poor carbon sink as compared with the western part of the delta.
fresh water of Himalayan glaciers fails to reach the central part due to heavy siltation and clogging of the Bidyadhari channel.
Credits, that can be bought or sold in the market at the prevailing price, gives the owner the right to emit carbon dioxide after paying for it.
