Economic Impact of Groundwater Depletion on Agricultural Sustainability

Abstract

Groundwater is a critical resource supporting global agricultural production, food security, and rural livelihoods; however, increasing groundwater depletion has emerged as a major challenge to agricultural sustainability. This review examines the economic impacts of groundwater depletion on agricultural systems by synthesizing existing literature on groundwater use, depletion drivers, economic consequences, sustainability implications, and management strategies. The review highlights that excessive groundwater extraction, climate variability, inefficient irrigation practices, and weak governance contribute to declining aquifer levels and increased water insecurity. Groundwater depletion increases irrigation costs, reduces crop productivity, decreases farm profitability, and threatens rural livelihoods and food security. Furthermore, it creates environmental challenges, including aquifer degradation, land subsidence, and ecosystem disruption. The study emphasizes the importance of integrated groundwater management approaches involving efficient irrigation technologies, groundwater recharge, crop diversification, economic incentives, and effective governance frameworks. Future research should focus on hydro-economic modeling, digital technologies, climate-resilient agriculture, and participatory groundwater governance to enhance agricultural resilience and ensure sustainable groundwater use under increasing climate and resource pressures.
