粮食与营养安全研究评述及展望.

Global food security has aroused great concerns in developing areas. In most developing countries, triple burdens of hunger, under- nutrition (inadequate intake of macroand 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.
