数据简介
本报告是首份从环境角度分析全球食物浪费影响的研究报告，它具体论述了食物浪费给气候、水土利用和生物多样性带来的后果。报告指出，每年约有28%的耕地资源因食品浪费而徒劳无功，由此产生的灌溉用水浪费量达250立方千米。

食物浪费足迹对自然资源的影响 Executive summary FAO estimates that each year， approximately one-third of all food produced for human consumption in I the world is lost or wasted. This food wastage represents a missed opportunity to improve global food security， but also to mitigate environmental impacts and resources use from food chains. Although there ! is today a wide recognition of the major environmental implications of food production， no study has yet analysed the impacts of global food wastage from an environmental perspective. This FAO study provides a global account of the environmental footprint of food wastage （i.e. both food loss and food waste） along the food supply chain， focusing on impacts on climate， water， land and bio- diversity. A model has been developed to answer two key questions： what is the magnitude of food wastage impacts on the environment； and what are the main sources of these impacts， in terms of re- gions， commodities， and phases of the food supply chain involved - with a view to identify“environmen- tal hotspots”related to food wastage. The scope of this study is global： the world has been divided in seven regions， and a wide range of agricul- tural products - representing eight major food commodity groups - has been considered. Impact of food wastage has been assessed along the complete supply chain， from the field to the end-of-life of food. 【更多详情，请下载：食物浪费足迹对自然资源的影响】
