Abstract
CONTEXT
Water, energy, and food systems have been deteriorating in security, stability, and sustainability throughout their extraction, production, and utilization, forcing the water-energy-food nexus to face security issues such as competition and mismatch between the systems' resources and environmental pollution. Consequently, a holistic evaluation of sustainable development among these systems is necessary, employing a suitability-focused perspective.
OBJECTIVE
This study defined suitability connotation in terms of the internal and external environments of the water-energy-food nexus. Based on the resource supply, resource conversion, and environmental impact of the suitability connotation, plus the fact that water is a strategic resource for energy and food industries, water suitability is essential for the sustainable development of the system's resources. Hence, the primary goal is to illustrate the suitability and suitability effects of water use in energy and food industries, to guarantee the sustainable development of industrial water use.
METHODS
A sustainable assessment framework for suitability with the water system as the core was constructed based on the Haken model, and China was selected for a case study. On this basis, using the water footprint theory and index system method, the suitability effects of industrial water use were evaluated by adding the perspectives of security, stability, and sustainability of the water-energy-food nexus.
RESULTS AND CONCLUSIONS
The results showed that Hebei, Shandong, Ningxia, and Xinjiang had better suitability in 2019, and the provinces with poor suitability were Shaanxi, Jilin, and Heilongjiang, reaching 1.00, 0.29, and 0.27, respectively. Hence, the Haken model identified the order parameter of water use in energy and food production. The model was used to construct multiple scenarios, and multidimensional adjustment measures were proposed to improve resource suitability among industries. From 1997 to 2019, all provinces demonstrated a consistent improvement in suitability effects.
SIGNIFICANCE
The suitability assessment can differentiate the degree of competition and resource matching between water-energy-food systems and serve the sustainable management of industrial production. By analyzing the water suitability in energy and food industries, the adjustment measures can optimize the water allocation for agriculture and industry, guarantee the security of resources, and maintain the system's sustainable development.
期刊介绍：
Agricultural Systems is an international journal that deals with interactions - among the components of agricultural systems, among hierarchical levels of agricultural systems, between agricultural and other land use systems, and between agricultural systems and their natural, social and economic environments.
The scope includes the development and application of systems analysis methodologies in the following areas:
Systems approaches in the sustainable intensification of agriculture; pathways for sustainable intensification; crop-livestock integration; farm-level resource allocation; quantification of benefits and trade-offs at farm to landscape levels; integrative, participatory and dynamic modelling approaches for qualitative and quantitative assessments of agricultural systems and decision making;
The interactions between agricultural and non-agricultural landscapes; the multiple services of agricultural systems; food security and the environment;
Global change and adaptation science; transformational adaptations as driven by changes in climate, policy, values and attitudes influencing the design of farming systems;
Development and application of farming systems design tools and methods for impact, scenario and case study analysis; managing the complexities of dynamic agricultural systems; innovation systems and multi stakeholder arrangements that support or promote change and (or) inform policy decisions.
