Sustainable Intensification of agriculture is a means to meet increasing future food demand in regions with rapidly growing populations and economies. In many of these regions, productivity is currently low. Increasing productivity while limiting additional use of resources such as water and land is therefore key to providing demanded and nutritious food in these countries. To model sustainable intensification, we build an opt...

Smallholders make up the vast majority of farms globally in terms of numbers (over 400 million), cultivate around 20% of global cropland, and produce 30% of global food. Although 70-80% of smallholders are located in areas already facing water scarcity which may be further exacerbated by climate change and population and economic growth, little is known about the relationship between smallholder farming and water scarcity. Thi...

Farms are not homogeneous. Smaller farms generally have different planted crops, yields, agricultural inputs, and irrigation applications compared to larger farms. However, gridded farm-size-specific data that are moreover crop specific, are currently lacking. This obscures our understanding of differences between small-scale and large-scale farms, e.g., with respect to climate change adaptation and mitigation strategies, cont...
