外文摘要：Nitrogen(N)is an essential nutrient for food production.The rapid increase in population requires high inputs of N to meet the growing food demand.If not managed well,the substantial loss of N from the food system has multiple impacts on grain yield,air and water pollution,and the economic benefits of agricultural.Multi-objective(food security,environmental sustainability and economic sustainability)synergistic consideration of N management in the food system is still lacking.This study employed strategies for optimizing N management in the food system,using Quzhou County as a typical example on the North China Plain.Firstly,a food chain approach was adopted to understand drivers and reasons behind N losses from the food system.Secondly,a top-down approach was used to define multi-objective N management,taking into consideration food security,environmental sustainability and economic sustainability.Multi-objective N management aims to reduce N losses to the environment and increase N use efficiencies,while simultaneously increasing yields and economic benefits.Thirdly,3R(reduce-retain-recycle)N management strategies were identified for specific crops and animals through a bottom-up approach and then analyzed the potential of these strategies to achieve the multi-objectives.Finally,there is a discussion of how to engage different stakeholders to promote the technologies implementation.This study provides new insights into the synergistic achievement of multi-objective N management in the food system and the development of environmentally-friendly agriculture.
