Socio-economic impact on vulnerability of tropical forests of Eastern Ghats using hybrid modelling

摘要: Forest vulnerability assessment has been proven paramount from regional to global scale in order determine the natural as well socio-economic pressure exerted on ecosystem. The hybrid of Analytical Hierarchy Process (AHP) with Weighted Overlay Modelling (WOM) be effective and yielded desirable results greater accuracies. In AHP, highest weights were assigned forest edge (DFE) (0.27) followed by roads (DRo) (0.22), shifting cultivation (0.11) settlements whereas parameters river, slope, elevation Normalized Differential Vegetation Index (NDVI) given lower priority values 0.09, 0.08, 0.08 0.04, respectively. Among total 8856 number grids 1 km2 dimension, 1126 (12.71%) are under very high medium classes share 682 (7.70%) 3 (0.03%), respectively geographic area district. Anthropogenic Disturbance (ADI) ranged 4.6 61.5 1429.57 km2 was common between overall anthropogenically indicating that is occurring mostly due activities. causes may attributed operation two major mines three industries which one practices tribal dominated REDD + programmes can implemented at community levels strengthening department local communities for better management resources through indigenous techniques without compromising livelihood developments.
