Research Article // Optimization of agricultural resources in water-energy-food nexus in complex environment: A perspective on multienergy coordination

By Mo Li and colleagues. This study provides an optimization pathway for the sustainable development of WEFN systems in irrigated agricultural areas. A modeling approach for the synergistic and optimal regulation of water and soil energy resources in WEFN systems is established from a coordinated multienergy perspective.

Abstract

Synergistic regulation of various agricultural resources in agricultural water-energy-food nexus systems is important for understanding the key regulatory processes and related synergistic relationships. However, regulation with the goal of multienergy interaction and coordination to adapt to environmental changes is extremely challenging. As a solution to the problem, an uncertainty-based modeling approach is proposed for the optimal regulation of water, soil and energy resources from a multienergy synergy perspective by integrating multiobjective nonlinear programming, left–right type fuzzy numbers and credibility programming into a framework. The approach aims to assess the interactions and synergistic relationships among biomass electrical energy, light energy, and hydroelectric energy, clarify the dynamic characteristics of resource allocation and socioeconomic and environmental effects, and capture the high uncertainty in the nexus area. This study contributes to the efficient and sustainable management of agricultural water, energy and land resources. The approach was tested and implemented based on a case study of Jinxi Irrigation District in China. The results reveal that there are trade-offs and games among the light use efficiency, hydroelectric energy and biomass energy, and their coordination enhances the system synergy among resources, the economy and the environment by 12.22%, with a 2.67% increase in the irrigation water use efficiency and a 4.92% increase in the energy use efficiency. Uncertainties significantly affect the synergy among multiple energies. More water will promote collaborative energy management, with the coordination development degree will increase by 2.20% when the water quantity increases by 4.16%, however, it accompanied higher water scarcity risks.
