ABSTRACT
This research assesses land suitable for organic farming in Mandya Taluk through a
combined method involving Geographic Information System (GIS), Remote Sensing (RS), and Multi-Criteria Decision Analysis (MCDA). Essential soil, climatic, and topographic factors such as soil moisture, organic carbon content, texture, actual evapotranspiration, rainfall variability, temperature, drought intensity, and terrain roughness were examined and prioritized through the Analytic Hierarchy Process (AHP). The standardized thematic layers were integrated using Weighted Overlay Analysis to create a map for organic farming suitability. The findings categorized the study region into three suitability zones: highly suitable (13.28%), moderately suitable (15.62%), and low suitable (71.10%). Particularly suitable areas are primarily found in the southern sections of Mandya Taluk, marked by beneficial soil qualities, sufficient moisture levels, gentle landscapes, and appropriate climate condition
