Abstract

Three vital sources of Water-Energy-Food (WEF) are inextricably interrelated so that may also produce environmental impacts such as greenhouse gas emissions in production/delivery process. Therefore, green-house-gas emission control plays a key role in WEF nexus management. Effective planning and management of limited WEF resources to meet current and future socioeconomic demands for sustainable development is challenging. Nexus management for WEF security necessitates integrated tools that are useful for effective planning and management strategies and policies. Hence, the comprehensive tools should be used for identifying the trade-offs and interactions among various sectors of water, energy, and food. In this study, the nexus in the integrated management of the sources by optimisation method is investigated. Also, a hypothetical optimisation model of the water, energy, and food nexus is examined. This model is applied to quantitatively analyse the interrelationships and trade-offs among system components including energy supply, electricity generation, water supply-demand, food production, and mitigation of environmental impacts. The results demonstrated how these types of analyses could be helpful for decision makers and stakeholders to make cost-effective decisions for optimal WEF management.
