Human - Wildlife conflict and forest fragmentation linkages in Northern Western ghats
- MPhil EI (91717008)
Western Ghats is a region of high biodiversity and endemism, starts from Tapti river in Gujarat and extending up to Kanyakumari at the southernmost tip of the Indian Peninsula. It has an area of 1,64000 km 2 , covers parts of Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu states. Geo-informatics approach is increasingly used to monitor land use change as well as forest fragmentation due to availability of Landsat satellite data. The Northern Western Ghats has experienced extensive deforestation and forest fragmentation due to increased anthropogenic pressures. The aim of this study is to analyze the changes in land cover and forest fragmentation that occurred in 2018 in NWG region in India using Landsat 8 OLI/TIRS and GRASS GIS software. Population density computed for NWG taluks to understand land use pattern in the study region. Forest intactness is measured by the proportion of four spatial patterns i.e. core, perforated, edge, interior and patches. NWG covers an area of 65, 105 sq. km and covers parts of Gujarat, Maharashtra and Goa states. Land use map of NWG showed that agriculture is predominant land use that covers 32.82% of the area. Forest fragmentation at the landscape level showed 59% area under non-forest category due to increase in agriculture land and development activities. Fragmentation map depicts that conflict occurred mainly in patch and perforated areas of NWG. Human-wildlife conflict analysis showed that elephant and gaur are the main wild species which are involved in crop depredation, livestock depredation and human attack, therefore initiates conflict with indigenous people. Human-wildlife conflict linkage with fragmentation depicts that there are few number of corridors present in NWG. The overall results indicate that anthropogenic activities are the main causes of the loss of forest cover, forest fragmentation and human-wildlife conflict. An increase in the area of cropland and barren land due to fragmentation contributed to the formation of wasteland or non-forest land in this region. Determining the trend and the rate of land cover conversion is necessary for development planners to establish a rational land use policy.
