dc.descriptionGroundwater resources in India are increasingly stressed due to unsustainable extraction, climate variability and rising demand. In Odisha, despite an average annual rainfall of about 1,452 mm, agriculture remains largely rainfed and vulnerable to climatic shocks. While surface water currently supports the majority of irrigation, groundwater use has grown substantially over the past decade, increasing the urgency for strategic groundwater management. Managed Aquifer Recharge (MAR) offers a promising climate adaptation strategy by enhancing groundwater storage, improving irrigation reliability and building resilience against drought and rainfall variability. This study presents a state-scale spatial suitability assessment for MAR in Odisha using a GIS-based multi-criteria framework. The analysis integrates hydrogeological parameters (aquifer type, soil characteristics, slope, groundwater depth) with indicators of water availability for recharge and groundwater demand patterns. By combining physical feasibility with supply–demand considerations, the study moves beyond purely biophysical screening to identify zones where MAR is both technically suitable and contextually relevant for climate risk management. The outputs include a statewide MAR suitability map and characterization of priority districts and blocks. The results provide evidence-based guidance for targeted MAR investments and support sustainable, climate-resilient groundwater development planning in Odisha.
