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.

水-食物-能源关系的概念在过去十年中得到了广泛研究。在本文中，我们将这一概念扩展到包括环境、经济和社会方面以及基于生命周期评估的思维。我们提出了一套环境足迹评估、生命周期评估和社会经济评估指标，并使用开发的水-土地-食物-能源-环境-经济-社会关系系统动态模型 (SD-WLF3ESN) 计算它们。开发的模型用于预测 2016-2030 年期间美国西部伊利湖盆地 (WLEB) 玉米作物的 WLF3ESN。该预测基于 WLEB 县级的人口、土地、产量、作物使用以及作物生产成本和回报的情景。开发了 WLEB 中玉米作物的 WLF3ESN 矩阵。
