能源、水和粮食政策领域有许多相互交织的关切，从确保获得服务，到环境影响，再到价格波动。这些问题在这三个“领域”中以非常不同的方式表现出来，但其影响往往是密切相关的。事先确定这些相互关系对于帮助瞄准协同效应和避免潜在的紧张局势非常重要。要解决如此广泛的可能主题，需要系统思维。本文主要从发展中国家的角度，通过案例研究，简要描述了高级别聚集的一些联系，以得出解决这种联系的一些有希望的方向。为此目的，我们还介绍了专门处理这一联系的模拟框架的特点，从而可以为更有效的国家政策和条例提供信息。虽然环境问题通常是共同考虑这三个领域的“凝聚力原则”，但由于缺乏准入而产生的巨大不平等表明，与经济和安全相关的问题可能是推动变革的更强大动力。最后，考虑到复杂的相互作用，工业化国家和发展中国家都需要新的机构能力。(C)2011爱思唯尔有限公司。保留所有权利。
The areas of energy, water and food policy have numerous interwoven concerns ranging from ensuring access to services, to environmental impacts to price volatility. These issues manifest in very different ways in each of the three "spheres", but often the impacts are closely related. Identifying these interrelationships a priori is of great importance to help target synergies and avoid potential tensions. Systems thinking is required to address such a wide swath of possible topics. This paper briefly describes some of the linkages at a high-level of aggregation - primarily from a developing country perspective - and via case studies, to arrive at some promising directions for addressing the nexus. To that end, we also present the attributes of a modelling framework that specifically addresses the nexus, and can thus serve to inform more effective national policies and regulations. While environmental issues are normally the 'cohesive principle' from which the three areas are considered jointly, the enormous inequalities arising from a lack of access suggest that economic and security-related issues may be stronger motivators of change. Finally, consideration of the complex interactions will require new institutional capacity both in industrialised and developing countries. (C) 2011 Elsevier Ltd. All rights reserved.
