In the context of the fight against climate change, energy system optimization models are becoming increasingly useful for this purpose. These models enable us to represent and analyse environmentally impactful sectors, such as the energy and agricultural ones. Currently, numerous sector-specific models are available for in-depth impact assessment. However, these models frequently lack a holistic perspective, neglecting to account for the interconnections between the sector under analysis and other related sectors, e.g. water and land use. In response to these issues, a recent approach called the Water Energy Food (WEF) Nexus has gained growing relevance. This approach emphasizes the significance of adopting a comprehensive perspective in managing and optimizing the intricate interconnections among water, energy, and food systems.
