Groundwater Management for Sustainable Water Resources

Groundwater underpins more than a third of global freshwater withdrawals, sustaining agriculture, industry and ecosystems. However, intensive abstraction, contamination and climate variability have driven widespread aquifer depletion, land subsidence and baseflow reduction, threatening water security and ecosystem function. Sustainable management requires a shift from uncontrolled pumping towards integrated water-resources planning, combining accurate monitoring, aquifer modelling and economic incentives with demand-side measures such as efficient irrigation and urban conservation. Techniques such as managed aquifer recharge, conjunctive use of surface and groundwater, and adaptive governance frameworks have emerged to balance short-term demands with long-term aquifer health. Effective policies hinge on stakeholder engagement, interdisciplinary science–policy interfaces and the resolution of uncertainties in recharge estimates and usage patterns. Globally, case studies in arid croplands, drought-prone basins and rapidly urbanising regions illustrate both the challenges of halting overdraft and the potential for recovery when management is guided by robust data and institutional support.

Research from Nature Portfolio

Recent studies have quantified planetary-scale declines and emergent recoveries in aquifer levels, revealing widespread rates of groundwater deepening exceeding half a metre per year in arid croplands alongside instances of resurgence following policy interventions and managed recharge. Scenario modelling linking climate, water and food systems has demonstrated that simply halting overdraft can jeopardise food security unless complemented by measures such as improved precipitation capture, dietary shifts and investment in agronomic research. High-resolution mapping of irrigation expansion has shown that over half of new irrigated areas have emerged in water-stressed regions since 2000, highlighting the misalignment between agricultural intensification and resource availability and underscoring the need for spatially targeted management.

The graph below shows the total number of articles in groundwater management for sustainable water resources across all publications each year (not limited to Nature Index journals).

Technical terms

Aquifer recharge: The process by which groundwater reserves are replenished through natural infiltration or artificial injection.

Managed aquifer recharge: Deliberate enhancement of groundwater storage using engineered structures or diversion of surface water to aquifers.

Groundwater overdraft: The condition where groundwater extraction exceeds recharge over an extended period, leading to declining water tables.

Safe yield: The long-term average rate of groundwater withdrawal that does not cause undesirable effects on aquifer systems.

Groundwater sustainability: The capacity to use groundwater resources to meet current demands without compromising ecosystem services or future availability.

Consumptive use: The portion of abstracted water that is evaporated, transpired, incorporated into products or otherwise removed from immediate reuse.
