ABSTRACTThe comprehensive knowledge of the ecological fragility of a region is quintessential for evolving strategies forthe conservation of the area. This entails identifying factors responsible for ecological sensitiveness, includinglandscape dynamics, future transitions to mitigate the problems of haphazard and uncontrolled developmentapproaches. The escalating anthropogenic pressures leading to over-exploitation of natural resources and unabatedgreenhouse gas emissions have contributed to global warming leading to changes in the climate and depletion ofnatural resources. The forest dynamics for the Mysore district were assessed using temporal remote sensing dataand the field data and predicted future scenarios of transformation, which helps in evolving appropriatemanagement strategies. Ecological sensitive regions at decentralized levels (grids of 5’ × 5’ or 9 km× 9 km) havebeen identified in Mysore district, Karnataka State, India, through a composite metric based on bio, geo, hydro,climatic, and ecological factors with the social aspects. This information was compiled from the field through anatural environment survey at representative grids and an extensive literature review at the district level.Forest dynamics were assessed using a supervised classifier based on the Gaussian maximum likelihoodclassifier using temporal remote sensing (1989 to 2019) Landsat data. The study showed an increase in agriculturallands in Mysore from 64.4% (1989) to 68.6% (2019). The forest range of the Mysore was dominated by the drydeciduous and moist deciduous forest in the Bandipuara and Nagar holé reserved forest. Anthropogenic activitiessuch as urbanization, eco-tourism, etc., have resulted in the decline of forest cover from 19.39% (1989) to13.08% in 2019. The fragmentation analysis showed a decline of contiguous interior forest from 50.66% to42.41% (1989 to 2019) in Mysore. Likely land-use scenario reveals an increase in built-up from 3.03 to 4.31%(2029) for the loss of forest area from 15.51% (2019) to 15.42% (2029). Computation of spatial matrices provesthe higher urbanization and loss of forest cover in the outskirts of city centers. Integrating geo-climatic, social,hydrological, and ecological parameters for each grid helped delineate ESR based on the aggregate values.Fourteen grids (17.07%) in Mysore fall in ESR 1, indicating the highest sensitivity. 21.95% in ESR2 (highersensitivity), 58.5% constitute ESR 3 (high sensitivity) and the rest is 2.43% in ESR 4 (moderate sensitivity). Theregion-specific sustainable development path with cluster approaches would enhance job opportunities andoptimize local resource use at each panchayat (grid) level with negligible effects on ecosystem health
