Abstract

Bioenergy, specifically produced from crop residue is land and water extensive and should not interfere with food nutrition, water supply, and land use changes. We propose a novel strategy hinging on optimal land allocation in the food-energy-water nexus for various crops to maximize the food and bioenergy production values while minimizing water consumption and satisfying nutritional and dietary constraints. The study is conducted for three regions in the Punjab, Maharashtra, and Madhya Pradesh, the states of India, respectively for the monsoon and winter seasons. Remarkably, 33 % increased bioenergy production value, and up to 92 % reduced water consumption can be achieved in all the regions in the monsoon season even with improved food production except in Punjab. Further, water consumption can be reduced substantially up to 81 % in the winter season. Our work showcases that local and inter-regional cooperation helps to obtain sustainable bioenergy production.
