摘要

This study investigates the impacts of groundwater over-exploitation on environmental, economic, and social factors, with an emphasis on addressing these issues holistically to ensure a sustainable global water supply. For the first time, it identifies the Sustainable Development Targets (SDTs) related to groundwater management practices aimed at reducing over-exploitation. The research aligns water management strategies with global sustainability objectives to ensure long-term water security and stresses the importance of comprehensive policies balancing environmental, social, and economic factors in groundwater use. The study uses Geographic Information System-based Multi-Criteria Decision Analysis (GIS-MCDA) to analyze ten thematic maps, including hydrological, geological, and topographic layers, for the Jeypore block in Koraput, Odisha. The analysis revealed that 25.36% of the study area falls under the high susceptibility index (SI) category, 51.25% under medium SI, and 23.39% under low SI. A strong correlation between the computed SI values and field measurements of piezometric water levels was observed, confirming the model’s reliability with a high coefficient of determination (R² = 0.94). Sensitivity analysis identified distance from the feeding fault (DFF), hydraulic conductivity (HC), and land surface elevation as the most significant factors influencing groundwater susceptibility. The results highlight the necessity of effective management of water resources in water shortage locations and are in line with important SDGs, including the eradication of poverty and hunger, water access, economic growth, and environment protection.
