Enabling smallholder farmers to sustainably improve their food, energy and water nexus while achieving environmental and economic benefits

Traditional cropping practices in the Eastern Gangetic Plains, South Asia, are resource intensive, requiring large inputs of water, energy and human labor. They are also inefficient, with relatively low productivity for the inputs used although the climate, soil and water resources of the region indicate that greater productivity is achievable. In on-farm experiments conducted across three countries (Bangladesh, India, Nepal) we compared the performance of traditional and improved management practices to understand which better facilitated the production of food-grain crops while reducing energy and water demands, thus improving the sustainability of cropping system energy requirements. Benefits of improved over traditional management practices included increases of up to 10% in crop grain yields; up to 19% in water productivity; up to…
