Arable land area in South Asia is declining while cereal demand is increasing. Bangladesh emphasizes surface water irrigation (SWI) for sustainable intensification. Remotely sensed, geospatial, and farmers’ yield data were integrated to target SWI. 20,800 and 103,000 ha of fallow and rainfed cropland could benefit from SWI. SWI policy could substantially increase maize and wheat, but not rice production.
