چکیده

Amidst the growing population, urbanization, globalization, and economic growth, along with impacts of climate change, decision-makers, stakeholders, researchers need tools for better assessment communication highly interconnected food–energy–water (FEW) nexus. This study aimed to identify critical periods water resources management robust decision-making at Using a 4610 ha agricultural watershed as pilot site, historical data (2006–2012), scientific literature values, SWAT model simulations were utilized map out throughout season corn soybeans. The results indicate that soil deficits are primarily seen in June July, average surpluses ranging from −134.7 +145.3 mm during period. Corresponding quality include monthly surface nitrate-N, subsurface soluble phosphorus losses up 0.026, 0.26, 0.0013 kg/ha, respectively, over season. Estimated fuel requirements practices ranged 24.7 170.3 L/ha, while estimated carbon emissions 0.3 2.7 kg CO2/L. A composite look all FEW nexus elements showed occurred early late season—primarily related quality—and mid-season, quantity. suggests adapt other across line respective needs. methodologies developed this provide framework which spatial, temporal, can be implemented improved areas.
