A study carried out by the IIRS has predicted a depletion of 9,007.14 square km (2.94 per cent) of forests in parts of Assam and Arunachal Pradesh by 2028.
A report published in the The Telegraph stated that the study – ‘Forest Cover Monitoring and Prediction in a Lesser Himalayan Elephant Landscape’ – published in the current issue of Current Science, says deforestation and loss of wildlife habitat in Upper Assam is likely to influence not only adjoining Bhutan and Arunachal Pradesh but Lower Assam as well. The IIRS is under the Indian Space Research Organisation (ISRO).
The report further stated that scientists involved in the study said they monitored the depletion of forest cover in parts of Assam and Arunachal Pradesh over 42,375 square km in an elephant landscape falling in the Lesser Himalaya in the North East. The study, which covered a vast elephant landscape spread across West Bengal-Assam, Assam-Bhutan and Assam-Arunachal Pradesh borders in the lesser Himalayas, found a loss of about 7,590 square km (17.92 per cent) of forest cover from 1924 to 2009.
This was also found by US Army topographic maps (1924) and multi-date satellite images. The forest cover of 2028 was predicted using the 2000-2009 depletion of forests study and Cellular Automata Markov Model (CAMM). As elephants are long-ranging animals and are distributed across the landscape, it is important to carry out studies covering large areas to address the habitat status over time, which can be used for effective habitat conservation.
