Title

Vegetation coverage change and risk assessment- A case study of Chandubi Lake, Assam

Abstract

The present study examines on two major issues. Firstly, the study of vegetation loss and secondly to map the wetland loss over 16 years from 2000 to 2016 using Remote sensing, GIS (Geographic Information System) analysis. This study is an attempt to measure Vegetation cover changes and to evaluate Wetland loss. Further, it gives insights for estimating the types of vegetation decline in that time period. The data used in the study include LANDSAT 5 and LANDSAT 8 satellite imagery of three different years 2000, 2008 and 2016. The temporospatial dynamics of surrounding vegetation and wetland areas have been studied using NDVI (Normalized Difference Vegetation Index), MNDWI (Modified Normalized Difference Water Index) and NDBI (Normalized Difference Built Index). In addition, the paper highlights the present and future risk associated with vegetation and wetland loss due to threats from climate change and anthropogenic activities. It has been found that Chandubi beel area has shrunk from 25.89% in 2008 and 20.42% in 2016. The vegetation cover has rapidly declined from 2000 to 2016. In addition, the study revealed the aquatic vegetation growth was more from 2008 to 2016 whereas growth was steady from 2000 to 2016. Overall the wetland area has declined from 2000 to 2016 by 14.61 %. The Beel is significantly shrinking from 2000 to 2016 which indicates an urgent need for wetland health restoration as it harbors various endangered and vulnerable species of fishes, amphibians, reptiles, birds, mammals and plant species. The study highlights the need for Remote sensing for risk assessment study for facilitating the ways for its restoration.
