Summary

• We examine risks to current agricultural land to future changes in water availability. • We present a multiple model inter-comparison of future land demand and water availability. • Eleven percent of croplands and ten percent of grasslands are at risk from declining water availability. • Changes in diet and waste reduction offer a buffer against land loss and food insecurity. Rapidly increasing populations coupled with increased food demand requires either an expansion of agricultural land or sufficient production gains from current resources. However, in a changing world, reduced water availability might undermine improvements in crop and grass productivity and may disproportionately affect different parts of the world. Using multi-model studies, the potential trends, risks and uncertai
