The Empirical Analysis of Nexus for Water-Energy-Food to Sustainable Development

Purpose– The purpose of this study was to analyze the Water-Energy-Food(WEF) Nexus of Korea, China, and Japan in order to sustainable development. Design/methodology/approach–This study investigates water security, energy security, and food security of Korea, China, and Japan from 2000 to 2017. Based on augmented production function model and environmental Kuznets hypothesis, this study constructs the simultaneous equation, fixed effect model, sustainable development index, and Granger causality. Findings–First, principal component analysis was conducted to secure the representativeness of food security index and food security, water security index were also representative in deriving the sustainable development index. Second, the U-shaped relationship between economic growth and food security was analyzed in three countries: Korea, China, and Japan through the simultaneous equation of WEF Nexus. Third, in the future, Japan was analyzed to have a relatively larger decrease in the sustainable development index than China and Korea. Fourth, in the case of China, the WEF nexus relationship has a bilateral causal relationship between WEFs, and the bilateral causal relationship between water security and energy security in Korea and food security and water security in Japan. Research implications or Originality–Therefore, we need to strengthen the management of WEF Nexus and cooperate with policies and various stakeholders such as government and private institutions.
