消费端食物浪费：影响与行动

食物浪费已经成为全球性问题,引发社会各界广泛关注。消费端是造成食物浪费的重要环节,且呈日趋严重的趋势。消费端的食物浪费主要分为家庭食物浪费和在外食物浪费;消费端的食物浪费对国家粮食安全、资源环境、社会经济发展等方面均产生不同的影响;影响消费端食物浪费的重要因素包括社会经济发展水平、文化因素、人口特征、消费者的行为与意识等。目前对消费端食物浪费的研究多采用称重（或估算）和计量模型等方法,仍需要通过发展更合理的量化方法、建立更完整的理论模型、提出更完善的研究方法进行深入探究。此外,减少消费端食物浪费需要从政府、社会、个人等多角度出发,促使多方利益相关者形成合力应对消费端食物浪费问题。

Food waste at the consumer segment: Impact and action

Food waste has become a global problem, which causes widespread concern from the public. The consumption segment is an important part of food waste, and it is increasingly serious. Food waste at the consumer segment is mainly divided into household food waste and food waste outside home. Food waste at the consumer segment has different impacts on national food security, resources and environment, and social and economic development. Food waste at the consumption segment is affected by factors such as economic and social development, cultural background, demographic characteristics, and consumer behavior and awareness. At present, the study of food waste at the consumer segment mostly uses methods such as weighing (or estimating) and measurement model. It still needs to be further explored by developing reasonable quantitative methods, establishing complete theoretical models and proposing concrete research methods. In addition, to reduce food waste at the consumer segment, we should encourage multi-stakeholders to make a joint effort to deal with food waste at the consumer segment from the perspectives of government, society, individuals and other angles.
