“…To address these challenges, the proposed IFCCP-WFN model aims to support the management of agricultural activities by considering constraints on water consumption, as well as fertilizer and pesticide utilization, and the associated uncertainties. Following previous studies [7,8,22,23], the IFCCP-WFN model's objective function includes crop sales revenues and the costs of using various resources, excluding labor costs. Therefore, the objective of the IFCCP-WFN model can be formulated as follows [7,8,22,23]:…”

This study discusses the planning of a regional-scale water–food nexus (WFN) system using an inexact fuzzy chance constraint programming (IFCCP) method. The IFCCP approach can handle uncertainties expressed as interval and fuzzy parameters, as well as the preferences of decision makers. An inexact fuzzy chance constraint programming-based water–food nexus (IFCCP-WFN) model has been developed for the City of Jinan with the consideration of various restrictions related to water and land availability, as well as food and vegetable demands. Solutions for the planting areas for different crops in different periods have been generated under the different preferences of decision makers. The water resource availability would be the priority factor affecting the WFN system under demanding conditions, in which wheat cultivation would be dominated by this factor under fuzzy confidence levels of 0.2 and 0.5, and the planting area of corn would be determined by this factor under high fuzzy confidence levels (e.g., 0.8). In addition, the reliability of irrigation would decrease with increasing fuzzy confidence levels under demanding conditions, limiting the planting areas for crops and leading to a decreasing trend of the system benefit. Adequate water resources would be available for irrigation under optimistic conditions, implying no significant contributions to the planting schemes. Nevertheless, increasing food loss rates would result in more planting areas to satisfy food requirements and thus a greater system benefit under advantageous conditions. Compared with the developed IFCCP-WFN model, the interval-linear-programming-based water–food nexus (ILP-WFN) model can merely reflect the lower and upper bounds of uncertain parameters and neglects the inherent distributional information within the fuzzy parameters. Thus, the ILP-WFN model is unable to reveal the inherent impacts of the fuzzy parameters on the resulting planting strategies.

“…Specifically, we observed an 8.4% decrease in the total cultivation area in the Sistan plain. Researchers such as (Leung Pah Hang et al, 2016;Xu et al, 2022) suggest that a decline in the cultivation area is a common outcome when agricultural production resources are optimally utilized using different approaches. However, this decline primarily pertains to the total cultivation area, and the analysis of individual crop cultivation areas does not necessarily reveal uniform decreases or increases.…”

“…Therefore, in the study area, expanding the cultivation areas of wheat and barley would lead to higher profits, reduced environmental impacts, and decreased GHG emissions. According to Xu et al (2022), the most significant decrease in the cultivation area was observed in Frontiers in Environmental Science frontiersin.org grain corn, which also resulted in the highest rate of GHG emissions. In their study, they replaced grain corn with vegetable crops as a strategy to reduce environmental pollutants.…”

Introduction: Due to the expansion of population, economic progress, urbanization, increasing food demands, and diversification of food systems, resources are being excessively exploited and degraded. This is compounded by the challenges posed by climate change and limited resources, as well as inadequate management practices. The concept of water-energy-food (WEF) nexus management recognizes the interdependencies among various resources, such as water, food, and energy, in order to promote sustainable resource management. By establishing a harmonious balance among different objectives, this approach aims to safeguard the well-being of both human societies and the environment, ensuring the fulfillment of needs and the preservation of benefits for both parties.Methods: In this study, the water-energy-food (WEF) nexus approach is applied to the Sistan plain, located in the southeastern region of Iran, to effectively redistribute production resources within the agricultural sector. The methodology employed is multi-objective programming, which incorporates various goals. These objectives encompass maximizing farmer revenue and energy derived from food production (measured in calories), while simultaneously minimizing greenhouse gas (GHG) emissions, irrigation water consumption, and overall energy consumption throughout the 2018–2019 crop year.Results: The findings of this study demonstrate that implementing the water-energy-food (WEF) nexus approach in the Sistan plain yields positive outcomes. Despite a reduction in the cultivation area, there is a notable shift towards growing more nutritious crops. This shift not only contributes to food security but also increases crop calorie production from 457.16 million to 565.19 million. Consequently, there is a decrease in irrigation water consumption from 261.62 million to 260.48 million cubic meters, energy consumption from 1400.13 million to 1396.81 million MJ per hectare, and greenhouse gas (GHG) emissions from 0.014 million to 0.0139 million tons per hectare.Discussion: Analyzing the physical and economic productivity reveals that GHG emissions had the highest productivity in terms of both physical and economic measures in Zahak County. As the WEF nexus approach aims to preserve and prevent environmental degradation, it is recommended to implement development and bio-balance policies utilizing this approach to ensure environmental conservation.

“…The traditional coupling of crop-livestock systems (CCLP) must be revitalized. 2 , 9 This does not simply imply a reversal of old traditions, but a redesign of current practices toward sustainable agriculture. Improved planting and breeding practices, manure management, and replacement of synthetic fertilizers with manure have demonstrated positive economic and environmental benefits.…”
