“…Water, energy, and land used and GHG emissions were evaluated under different scenarios to investigate the future trends. Karamian et al (2021) [47] investigated a novel water-energy-food indicator (WEFI) by integrating six indices for management purposes at farm scale. Chai et al (2020) [48] added new dimensions to the water-energy-food nexus, which were economic, social, and environmental aspects.…”

The water–energy–food (WEF) nexus is drawing much attention in scholarly literature as a novel alternative to address complex resources and achieve resource security. The aim of this study is to analyze and review existing nexus studies to investigate the current status of nexus research worldwide. This study used a narrative review approach to provide a comprehensive overview on the WEF nexus using a variety of databases. It is indicated that the majority of studies in Asia and Africa focused on the water–energy–food (WEF) nexus. China and Brazil had the largest nexus research. Based on the existing literature, most of attention has been paid to food production. However, food consumption patterns and dietary change are rarely evaluated, and there is a lack of study on impacts of dietary change on the WEF nexus. Moreover, there is a lack of frameworks for the evaluation of the WEF nexus under dietary change scenarios. The major challenge of the nexus approach is data availability in crop production, which can be solved by using remote sensing data. There is a lack of standard and conceptual frameworks for nexus assessment and, then, an essential need to provide a new holistic and standard approach that be applicable worldwide to increase connections between researchers and decision makers, as well as the applicability of nexus approaches. Future research must couple the development of a holistic standard approach with experimental tests in different areas, involving interdisciplinary research groups able to carry out all the experimental activities, the numerical simulations, and the statistical analyses of climatic time series (in a climate change perspective) indispensable to demonstrate the real benefits of using a WEF-derived nexus approach.

“…Generally, there are two main categories. First, in most studies, the WEF nexus is understood as the interaction between the three resource subsystems (or sectors) (Do et al, 2020;Islam et al, 2021;Wu et al, 2021), such as the water and energy consumption related to food production (Karamian et al, 2021), and demand and competition for water in the food and energy sectors (Niva et al, 2020). Such studies aim to describe and reveal the complex interlinkages among the three resource systems (Zhang et al, 2019a).…”

“…In previous studies, various indicators, such as e ciency, productivity and security of water, energy and food resources have been evaluated in the agricultural sector (Echchelh et al, 2018;Sanjuan-Delmas et al, 2018). However, researchers now state that all these criteria should be quanti ed and combined in the form of the WEF nexus concept (Zhang et al, 2018b;Radmehr et al 2021;Karamian et al, 2021). In this regard, in various studies, the WEF nexus index has been used as a comprehensive approach in agricultural systems (El-Gafy et al, 2017a, b;Fabiani et al, 2020, Gathala et al, 2020Sadeghi et al, 2020;Karamian et al, 2021).…”

The review of the literature shows that from a methodological point of view, due to the con ict between the goals of stakeholders in different sectors and complex relationships and feedbacks, the multi-objective programming model has been operationalized as an e cient and powerful tool at the national, regional and global levels in order to assess the WEF nexus.…”

Today, growing the production of the agricultural sector in order to meet the increasing demand of food is happening through excessive consumption of water resources, energy, chemical fertilizers and pesticides, especially in developing countries. Therefore, the present study aims to design a new approach for sustainable management of resources and realization of clean production in the agricultural sector. In order to design the new approach of the present study, the integration of two concepts of water-energy-food (WEF) nexus and decoupling pollution- agricultural growth (DEC) was used. The proposed approach is modeled through the multi-objective programming model by optimizing the WEF and DEC indices, which is the first research effort in this field. In this regard, the performance of this approach was evaluated in Jiroft county in Kerman province, Iran. The results of the study showed that the consumption of chemical fertilizers and pesticides in the optimal pattern with the simultaneous provision of WEF and gross margin (GM) goals (Optimal 1) is about 110 kg and 0.19 liters per hectare, respectively, more than the proposed pattern (Optimal 3). On the other hand, the consumption of water and energy resources in the optimal pattern with the simultaneous provision of DEC and GM goals (Optimal 2) is about 8785 cubic meters and 1108 MJ per hectare more than the proposed pattern (Optimal 3), respectively. Therefore, this approach, due to the simultaneous integration of two concepts of sustainable development in the agricultural sector, can overcome the weakness of the WEF nexus in not paying attention to the issues of environmental pollution affected by the use of chemical inputs and the weakness of separating pollution- agricultural growth in not paying attention to the management of water and energy resources in the agricultural sector.
