Golden, Duke University, Durham, NC, and accepted by Editorial Board Member B. L. Turner November 29, 2016 (received for review June 19, 2016) Urban expansion often occurs on croplands. However, there is little India, and other countries (7–9). Although cropland loss has scientific understanding of how global patterns of future urban become a significant concern in terms of food production and expansion will affect the world’s cultivated areas. Here, we combine livelihoods (10) for many countries, there is very little scientific spatially explicit projections of urban expansion with datasets on understanding of how future urban expansion and especially global croplands and crop yields. Our results show that urban ex- growth of MURs will affect croplands.
