The concept of the water-food-energy nexus has been widely studied in the past decade. In this paper we expand on this concept to include environmental, economic, and social aspects as well as life cycle assessment based thinking. We proposed a set of Environmental Footprint Assessment, Life Cycle Assessment, and Socio-Economic Assessment indicators and calculated them using a developed System Dynamic Model for Water-Land-Food-Energy-Environment-Economic-Social Nexus (SD-WLF3ESN). The developed model was applied to predict the WLF3ESN of the corn crop in the Western Lake Erie Basin (WLEB)-USA for the period 2016-2030. The prediction was based on scenarios for population, land, yield, crop use, and crop production costs and returns at the county level of WLEB. A matrix for WLF3ESN of the corn crop in WLEB was developed. This matrix can help in developing policies and strategies for managing the nexus in the basin.
