Fresh food cold supply chains (CSCs) feature high fresh food quality and safety, high energy consumption, and poor economic and environmental sustainability. Sustainable management of fresh food CSCs is critical. However, limited research has addressed the implementation of systematic good practices in sustainable fresh food CSCs in developing countries. Consequently, decision-makers lack empirical evidence to help them understand how companies successfully implement systematic good practices and how those good practices affect sustainability performance. This paper formulates a hybrid analytic hierarchy process-fuzzy technique for order preference by similarity to ideal solution (AHP-Fuzzy TOPSIS) decision framework to systematically explore the impact of good practices on the sustainability performance of fresh food CSCs in the context of a developing country such as China. The results of the integrated methodology show that China's CSC industry pays more attention to economic sustainability and that employee training is the most impactful good practice for improving the sustainability performance of fresh food CSCs. • A systematic study of good practice and sustainability performance indicators. • A fresh food CSC sustainability performance assessment framework applied in China. • Order of importance of sustainability performance assessment indicators. • Ranking of good practices to improve fresh food CSC sustainability performance.

Water, energy, and food (WEF) are pivotal resources for the sustainable development of human society. Integrated assessment of the sustainable WEF nexus is essential to enhance resource efficiency and security, but there is a crucial gap to be filled in assessing the coupling relationship among sustainable WEF subsystems and improving multi-sectoral synergy. In this paper, a comprehensive indicator system for sustainable WEF nexus assessment was constructed based on theme-based frameworks and nexus thinking, and the combination weighting method based on game theory (GT-CW), the improved TOPSIS method based on gray relation degree (GRD-ITOPSIS), and the coupling coordination model were proposed for integrated assessment. The sustainability of WEF nexus in 30 regions of China from 2010 to 2019 was assessed and the spatiotemporal differences of the coupling coordination degree of sustainable WEF nexus were analyzed. The results revealed that the sustainability of WEF subsystems evidently affected the overall sustainability of regional WEF nexus. The change range of sustainable WEF nexus in different years was slightly lower than that of a single subsystem. The sustainability of WEF subsystems were highly coupled, and the WEF nexus in each region was within the coordinated development range. However, most eastern regions were at the intermediate coordinated development stage, and some western regions maintained at primary coordinated development stage for a long time. According to the results analysis, specific policy recommendations were proposed. The findings of this study can provide a useful reference for developing countries to improve resource management and promote sustainable development.
