Abstract
 Agriculture is one of the largest consumers of water and energy. This paper evaluatedthe agricultural sustainability of the Chenmengquan irrigation district of China based on thewater–energy–food nexus. One objective weighting method and one subjective weighting methodwere integrated, based on game theory, and a matter–element model was constructed to evaluateagricultural sustainability for the research region. The sensitivity of each index to the evaluation classwas also analyzed. The results showed that agricultural sustainability was moderate in 2006–2012and high in 2012–2015. The indexes, which represent water-use efficiency and yield per unit areaof crops, had higher sensitivities in the context of the present case study. The results also indicatedthat agricultural sustainability had a comparatively positive trend between 2012 and 2015, and thatpesticide utilization was the most important issue for agricultural sustainability. The approachof using the combination of a weighting method, based upon game theory, and the use of thematter–element model provides a guide for the evaluation of agricultural sustainability
