“…Thanks to this, it is possible to limit our search area for multiobjective optimization. The obtained configurations are presented in flow diagrams where the selection of each technology for a year of operation is illustrated, for which they include configurations with different sources of water and energy depending on each scenario, and radar graphs that show the comparison between the security indices of the WEF nexus evaluated for the year 2019 with parameters obtained from water statistics in Mexico 49 and the values resulting from individual objectives.…”

The need to quantitatively measure the security of the water–energy–food (WEF) nexus sectors in a region is of great importance due to the vulnerability of each sector and the associated cost. This paper presents an approach for optimizing the security indices of the WEF nexus by analyzing the availability, accessibility, and sustainability of water, energy, and food resources. To maximize the security indices, a multi-objective mixed integer nonlinear programing model involving multiple stakeholders is presented. Through the model, the dependent variables for the optimization of the indices are described, and these in turn represent new and existing technologies considering the economic and environmental aspects. Furthermore, the optimization model results in different configurations when selecting technologies to satisfy high demands imposed by the population, maximizing the value of the evaluated indices, and improving the performance of the distribution network of the studied area. Different scenarios are designed to observe the behavior of the objective functions (minimizing the total annual cost, fresh water consumption, and greenhouse gas emissions) while maximizing the security of the WEF nexus; the indices are illustrated in radar graphs that allow identifying the interactions between the involved sectors. A case study of an area of Mexico with great development is analyzed due to its economic importance; however, the model is applicable to any region with the corresponding data and similar climatic characteristics. The results show the vulnerability of the distribution network and that it is possible to satisfy the demands of a region with the implementation of new policies that allow maximizing the values of the WEF nexus security indices. In general, the total annual cost and greenhouse gas emissions are dependent on the variations in the indices, and the indices associated with the energy sector fluctuate more in the analyzed scenarios.

It is interesting to note that the country of Iran is essential in terms of energy production and consumption, and the economy of Iran is mainly dependent on energy revenues. Therefore, thermal and hydropower plants consume water to produce various energy carriers. Considering that Iran is suffering from water stress, the nexus of water and energy becomes very important. This paper frames a comprehensive structure for Iran's energy subsystem within the Water, Energy, and Food (WEF) nexus system. The energy subsystem's supply and demand side in the proposed framework are formulated using data and physic-based equations. The presented framework addresses most interactions between WEF subsystems in a dynamic and adaptive setting. It is shown that through analysis of binding interactions between WEF, different management scenarios can boost the flexibility of the supply and demand side of the energy subsystem. In addition, by incorporating this framework, the water subsystem will manage the allocated and consumed water on the supply side and arrive at the most desirable outcome for the water sector. Also, the optimal cropping pattern could be evaluated based on energy consumption.

“…In contrast to existent practice-oriented WEF tools (Mohtar and Daher 2016, Martinez-Hernandez et al 2017b, Cansino-Loeza and Ponce-Ortega 2018, the structure of our approach for decision-support is separated into three main pillars: generic representation (OWEFE), data collection (WEFE Site Analyst), and configuration (iWEFEs Configurator). This enables the simple individual usage of single pillars and their application in other contexts and under the application of further methods.…”

The integrated approach to managing the fundamental resources for human life, namely, water, energy, food, and the environment as their irreplaceable foundation, presents a profound opportunity for sustainable development. However, despite their huge potential, integrated water, energy, food, and environment systems (iWEFEs) are rarely put into practice because of, among others, complexity and a lack of uniform and openly available models to describe, configure and simulate such systems. To fill this gap, we present the open modeling framework for integrated water, energy, food, and environment systems (OWEFE) based on the open energy modeling framework (OEMOF). OWEFE follows an open, cross-sectoral, and modular design approach to address crucial challenges for the project development of iWEFEs. In this study, we apply OWEFE for the first time to model a wastewater biogas system and an agrivoltaics system. The results of the OWEFE-based models are in the range of a conventional approach respectively of on-site measurements indicating the framework’s capability to model diverse iWEFEs. The wide application of the framework can improve the assessment, planning, and configuration of iWEFEs for sustainable and integrated infrastructure development.
