Abstract

To achieve the United Nations’ Sustainable Development Goal 2 on food and nutrition security by 2030, greater attention to effective food policies that reduce food insecurity and improve health is warranted. This systematic review and meta-analysis examined the impact of different types of government food policies (financial aid, food aid, technical support, capacity building, and land tenure management/food production) on food insecurity and health in numerous countries, and moderators involving study design, cultural context, and country economic advancement. Based on 148 studies and 273 effect sizes, we found that land tenure management/food production and a combination of policies were most effective in reducing food insecurity and in improving health. Study design moderated effects of food policies on food insecurity. Cultural contexts and country economic advancement moderated the effects of different types of food policies on food insecurity and health. This study has important implications for informing effective food policies in improving food insecurity and health by identifying the most effective types of food policies and the cultural and country economic contexts in which different types of food policies are most effective.

不同的粮食政策如何影响粮食不安全和健康？综述和荟萃分析

为了到2030年实现联合国关于粮食和营养安全的可持续发展目标2，有必要更加重视有效的粮食政策，以减少粮食不安全和改善健康。本系统综述和荟萃分析考察了许多国家不同类型的政府粮食政策（财政援助、粮食援助、技术支持、能力建设和土地使用权管理/粮食生产）对粮食不安全和健康的影响，以及涉及研究设计、文化背景和国家经济发展的调节因素。基于148项研究和273项效应大小，我们发现土地权制管理/粮食生产以及政策组合在减少粮食不安全和改善健康方面最为有效。研究设计缓和了粮食政策对粮食不安全的影响。文化背景和国家经济进步缓和了不同类型的粮食政策对粮食不安全和健康的影响。这项研究通过确定最有效的粮食政策类型以及不同类型的粮食政策最有效的文化和国家经济背景，对为有效的粮食政策提供信息以改善粮食不安全和健康具有重要意义。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
