Global assessment of urban and peri-urban agriculture: irrigated and rainfed croplands

Urban Farm DB summary

This study used spatial overlay analysis of global cropland and urban extent data to estimate the global area of urban and peri-urban irrigated and rainfed croplands. Urban irrigated croplands were estimated at approximately 24 Mha (11.0% of all irrigated croplands) with a cropping intensity of 1.48. Urban rainfed croplands were estimated at about 44 Mha (4.7% of all rainfed croplands) with a cropping intensity of 1.03. Additionally, 60% of all irrigated croplands and 35% of all rainfed croplands were found within 20 km of urban extents.
