what do you understand by changing area under forest and its impact on environment
Answers
The trend of such changes and their impact on natural environment as well as on socio-economic condition of the people are identified as the prime concern at this stage. The Umtrew Basin of North East India is a river basin covering an area of 1253.1sq km where the study has been carried out using satellite data and GIS techniques. The satellite data of Landsat MSS and IRS-1C LISS III for the years 1977, 1999, 2004 and 2007 respectively have been utilized for the study. In the present study an attempt has been made to identify the pattern of forest cover change using GIS analysis through which we could identify the degraded areas. In course of the present study an attempt has been made to formulate a strategy for maintaining environmental quality of the study area. A humble starting from the Umtrew Basin for such programme with an aim to replicate in other similar areas of the country has been considered as the application part of the study.
