SUSTAINABLE GROUNDWATER MANAGEMENT FOR AGRICULTURE

The report highlights that over one-quarter of global irrigated food production relies on unsustainable groundwater extraction, leading to land subsidence, saltwater intrusion, and ecological damage. It proposes four key strategies for sustainable management: measuring and managing data, setting sustainable extraction limits, enhancing recharge through managed and nature-based solutions, and reducing demand through crop shifting or fallowing. The authors emphasize that strong water governance and local partnerships are essential to implement these technical solutions effectively.

• Groundwater is a critical global resource, supporting drinking water for over two billion people, nearly half of all freshwater ecosystems, and 38% of water used for crop irrigation.
• A significant portion of global food production is at risk because more than 25% of irrigated food production depends on unsustainable groundwater extraction, with heavy concentrations in the US, Mexico, the Middle East, North Africa, India, Pakistan, and China.
• Climate change exacerbates groundwater depletion by altering precipitation patterns, increasing evaporation, and raising water demand due to heat stress, which forces farmers to increase pumping.
• Over-pumping leads to severe physical and environmental consequences, including the drying of residential wells, land subsidence (such as in California's Central Valley), and saltwater intrusion in coastal aquifers.
• Groundwater overdraft significantly impacts surface water systems; approximately 50% of all groundwater pumping captures river water, reducing streamflow and threatening ecological integrity in 15%–21% of all river basins.
• The report outlines four primary strategies for sustainable management: measuring and managing data, setting volumetric caps and allocations, enhancing recharge (via Managed Aquifer Recharge or nature-based solutions), and reducing demand.
• Efforts to reduce water use through irrigation efficiency often fail due to the 'irrigation efficiency paradox,' where farmers use saved water to expand irrigated areas or grow more crops rather than reducing total extraction.
• Effective groundwater management is fundamentally a governance challenge, requiring the inclusion of marginalized groups and the creation of collaborative partnerships between government, private sector, and community stakeholders.
