水、能源和食物是相互关联的，是人类福祉和环境目标的关键资源。单一部门的国家战略侧重于联系的个别部门，而不考虑其相互联系，可能导致严重的意想不到的后果。在本研究中，利用系统动态模型平台创建了一种新的动态行为分析方法，重点关注不同情景和替代方案下国家一级作物生产和消费产生的水-能源-粮食联合相互作用。发达的系统确定：(i)作物生产和消费的水和能源足迹；（二）虚拟水和能源进出口；（三）农产品贸易带来的全国节水节能平衡；(4)水-粮-能联系指数。一个来自埃及的案例研究被用来测试这个系统，并说明它的一些意义。这项研究说明了在制定国家战略时考虑水-粮食-能源关系的重要性。版权所有：John Wiley & Sons， Ltd。
Water, energy, and food are interrelated and critical resources for human well-being and environmental goals. Single-sector national strategies that focus on individual sectors of the nexus without considering their interconnections may lead to acute unanticipated consequences. In the present study, the system dynamic model platform was used to create a new approach to analysis of dynamic behaviour, focusing on joint water-energy-food interactions stemming from crop production and consumption at the national level under different scenarios and alternatives. The developed system determines: (i) water and energy footprints of crop production and consumption; (ii) virtual water and energy import and export; (iii) the national water and energy saving balance due to trade of agricultural commodities; and (iv) a water-food-energy nexus index. A case study from Egypt was used to test the system and illustrate some of its significance. The research illustrates the importance of considering the water-food-energy nexus when developing national strategies. Copyright (c) 2016 John Wiley & Sons, Ltd.
