Sustaining Agricultural Production under Increasing Water Scarcity: Adaptation Pathways and Institutional Conditions for Long-Term Water-Resource Sustainability

Water scarcity has become a major constraint on agricultural production, particularly in regions where recurrent drought, groundwater depletion, irrigation dependence and competing water demands increasingly affect the sustainability of farming systems. This paper examines the relationships between agricultural exposure to water scarcity, farmers’ adaptation strategies and sustainable water-resource management. The literature shows that water scarcity cannot be addressed exclusively through greater irrigation efficiency because technological improvements may be offset by production expansion, inappropriate crop allocation or continued groundwater overexploitation. Agricultural adaptation therefore involves a combination of efficient irrigation, crop and agronomic adjustments, climate-smart practices, improved farmer capabilities and alternative water resources. The paper also emphasizes the importance of governance, collective action, pricing mechanisms and institutional coordination in reconciling agricultural production with hydrological constraints. Wastewater reuse, precision irrigation, digital technologies and nature-based approaches provide additional opportunities for reducing pressure on conventional water sources, although their effectiveness remains dependent on local economic, environmental and institutional conditions. Overall, sustainable agricultural water management requires an integrated approach linking farm-level adaptation with resource allocation, technological change and governance. Maintaining agricultural productivity under increasing scarcity consequently depends on combining efficient water use with long-term conservation of groundwater, surface water and environmental resources.
