Summary
This multi-model study examined the intersection of future water availability and agricultural land vulnerability, finding that approximately 11% of global croplands and 10% of grasslands face productive capacity loss due to declining water resources. Africa, the Middle East, China, Europe and Asia emerge as particularly at-risk regions. The authors demonstrate that dietary shifts—notably reduced food waste and decreased meat consumption—offer the most substantial buffer against climate-driven land loss and associated food insecurity.
UK applicability
Europe is identified as a region of particular risk in this global analysis, suggesting UK agriculture may face water-related vulnerabilities despite relative water abundance in some regions. The findings support UK policy interest in sustainable intensification and dietary transition as resilience measures.
Key measures
Percentage of croplands and grasslands at risk from water scarcity; regional vulnerability mapping; land area loss projections; effectiveness of dietary change and food waste reduction as policy interventions
Outcomes reported
The study quantified the proportion of global croplands and grasslands vulnerable to reduced water availability and evaluated how dietary interventions might mitigate resulting land loss and food insecurity. Multi-model comparison assessed future land demand and water availability under climate change scenarios, with particular focus on regional vulnerability.
