为了促进对食品-能源-水（FEW）关系的理解和决策，我们开发了一个分水岭级别的综合技术-环境-经济模型（ITEEM）。 ITEEM是多种模型的集成，包括粮食加工、饮用水处理、废水处理（技术）模型；水文、水质、作物生产和养分循环（环境）的流域模型；评估总效益的经济模型，包括环境效益的非市场评估。应用不同的数据技术来开发基于计算机的模型的合适替代物，包括响应矩阵方法、人工神经网络和查找表。应用经验方程来开发经济和饮用水处理模型。模型之间的输入输出关系在统一的计算框架中制定。 ITEEM是一种空间半分布式动态模拟模型，可用于量化玉米带中各种管理实践、技术和政策干预对FEW系统的环境和社会经济影响。
To facilitate understanding and decision making in the food-energy-water (FEW) nexus context, we develop an integrated technology-environment-economics model (ITEEM) at a watershed scale. ITEEM is built as an integration of various models, including models for grain processing, drinking water treatment, and wastewater treatment (technology); a watershed model for hydrology, water quality, crop production, and nutrient cycling (environment); an economics model assessing total benefit, including non-market valuation of environmental benefits. Different data techniques are applied to develop suitable surrogates for computer-based models, including a response matrix method, artificial neural networks, and lookup tables. Empirical equations are applied to develop models of economics and drinking water treatment. The input-output relationships between the models are formulated in a unified computational framework. ITEEM, a spatially semi-distributed dynamic simulation model, can be used to quantify the environmental and socioeconomic impacts of various management practices, technologies, and policy interventions on FEW systems in the Corn Belt.
