 Iran's energy sector is heavily reliant on water resources, which makes it critical to understand how the two systems interact. This paper proposes a framework to analyze the interdependence between water, energy, and food, WEF, systems in Iran. The framework includes both supply and demand sides of the energy subsystem, as well as the water subsystem. By analyzing the interactions between these three systems, the authors were able to identify potential opportunities for improving efficiency and reducing waste. For example, they found that by managing the allocation and consumption of water, the energy subsystem can become more flexible and efficient. Additionally, the optimal cropping pattern can be determined based on energy consumption. This article was authored by Masood Vahabzadeh, Abbas Afshar, and Amir Molojoo.
