Optimization of Water-Energy-Food Nexus considering CO2 emissions from cropland: A case study in northwest Iran

نویسندگان

چکیده

Water-Energy-Food (WEF) Nexus and CO2 emissions for a farm in northwest Iran were analyzed to provide data support decision-makers formulating national strategies response climate change. In the analysis, input–output energy production of seven crop species (alfalfa, barley, silage corn, potato, rapeseed, sugar beet, wheat) was determined using six indicators, water, consumption, mass productivity, economic productivity. WEF index (WEFNI), calculated based on these showed highest (best) value corn lowest potato. Nitrogen fertilizer diesel fuel with an average 36.8% 30.6% total input greatest contributors demand. Because direct relationship between consumption emissions, potato cropping, had 5166 kg CO2eq ha?1. A comparison inputs revealed global warming potential. 1 MJ increase increased by 0.047, 0.049, 0.054, 0.046, 0.047 ha?1 alfalfa, wheat, respectively. Optimization assessments identify optimal cultivation pattern, emphasis maximized WEFNI minimized that wheat performed best under conditions studied.
