作者： shenggen fan Qiran Zhao Jingjing Wang Academy of Global Food Economics and Policy/College of Economics and Management China Agricultural UniversityBeijing 100083China

The call for agri-food system transformation is urgent in many global development agendas(UN 2023).Food systems have contributed to economic prosperity and feeding the world,but they are also associated with numerous challenges,including climate change,continued hunger,poor diets and malnutrition,and increasing disparities(Webb et al.2020;fanzo et al.2021).

农业领域新质生产力是引领现代农业变革的根本动力,也是实现农业高质量发展的重要抓手。发展农业领域新质生产力符合农业发展的新要求和新目标,为推进农业现代化提供了新的思路和机遇。由于农业自身的独特性以及我国“大国小农”的国情,相对于其他行业和其他国家,我国发展农业领域新质生产力的难度更大。发展农业领域新质生产力,要突破传统农业理念和思维,树立系统性的大食物观和大农业观,培育新型农业劳动者和企业家,强化农业前沿科技研究与运用,积极培育拓展涉农新产业、新业态、新商业模式。

Feeding More People on an Increasingly Fragile Planet: China's Food and Nutrition Security in a National and Global Context

引用

Journal of Integrative Agriculture 2014年第6期13卷 1193-1205页

作者： shenggen fan Joanna Brzeska International Food Policy Research Institute

Developing and developed countries alike are increasingly facing the dififcult question of how to feed more people amidst a host of emerging demographic, environmental, and health challenges. At the same time, in addition to food quantity, increased attention is being given to food quality attributes, in particular nutrition and safety. This is especially evident in China, where concerns are on the rise regarding the ability of China’s food production systems to deliver nutritious and safe food to a growing, urbanizing and more aflfuent population. These food and nutrition concerns come at a time when China is an increasingly inlfuential actor within the global food security network through activities such as production, consumption and trade. We argue that China has the opportunity to increase food and nutrition security both nationally and globally through a comprehensive policy agenda that focuses on institutional reforms, investments for and in agriculture, productive social safety nets, mutually beneifcial trade, and the exchange of know-how and technologies among developing countries and donors. This agenda will help China adapt its food production systems to the changing face of agriculture and to play a vital role in addressing the emerging challenges facing food and nutrition security within and beyond China in the coming decades.
