粮食与营养安全研究评述及展望

当前国际粮食安全局势堪忧,大多数发展中国家饥饿、营养素缺乏与营养过剩三重困境并存,实现全球粮食安全与营养安全的双重目标任重道远。本文梳理了95篇文献,旨在理清粮食与营养安全的发展脉络及演变规律,提出中国未来粮食与营养安全的研究重点。首先对全球粮食与营养安全的概念演变进行回顾,指出粮食安全概念由谷物供给总量安全到所有食物数量安全、再到食物质量与营养安全与可持续内涵的动态演化,由单一可供应维度向可供应、可获得性、可利用性、稳定性、可持续性多维度不断拓展。随后,从宏观国家层面梳理中国粮食与营养需求分析及预测、粮食生产能力和进口能力的相关研究,从微观家庭及个人层面评述收入、市场、城镇化、农户农业生产对食物消费及营养的影响。最后,基于未来城乡居民营养均衡发展目标,对中国粮食与营养安全研究的主要趋势和未来研究重点作出展望,指出未来展开对农业生产多样性、作物种植结构调整及作物营养强化,城镇化与市场建设的影响,城市中低收入人群和农村贫困人口营养问题的研究具有重大意义。

Food and nutrition security: A literature review and prospects for research

Global food security has aroused great concerns in developing areas. In most developing countries, triple burdens of hunger, under-nutrition (inadequate intake of macro- and micronutrients), and over-nourishment (in the form of overweight and obesity malnutrition) coexist. There is a long way to achieve the dual goals of food security and nutrition security. By tracing 95 literatures, this paper aims to figure out the concept development and evolution of food security and nutrition security, and put forward the research priorities of future food and nutrition security. The article explores the evolution of the concept of food security and nutrition security and narrates the evolutionary characteristics, and finds that the concept of food security evolves from adequate supply of cereals to all foods, then to foods quality and nutritional security and sustainable development, with the dimensions of food security extending from a single availability dimension to multiple dimensions of availability, accessibility, utilization, stability, and sustainability. Subsequently, we review the research on food and nutrition demand analysis and forecasting, the capacity of food production, and import impacts; furthermore, we review the impact of income, market, urbanization and farmers' agricultural production on food consumption and nutrition security at the family and individual levels. To achieve the goal of the balanced development of nutrition for urban and rural residents, the paper provides an outlook for future food and nutrition research and brings out four important fields deeply touched to extend study scope and depth for food and nutrition security research in China. This review work reveals that it is of great significance to conduct research on agricultural production diversity, crop planting structure adjustment and crop nutrition enhancement, the impacts of urbanization and market development, and the vulnerable residents' welfare on the nutrition enhancement.
