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

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.

Reform of China's Food Security Policies:Central Government Decentralizing Autonomous Management Right

Guaranteeing the food security is a fundamental state policy of China. Food security needs overall planning of central government,economic benefit allocation of local government,and increase of grain farmers' income. Through analysis on current situations and causes of China's food security,and comparative study on purposes and functions of foreign and domestic grain reserves,it came up with recommendations that central government should decentralize rights of grain production,reserve,sales,and management to grain producing areas and major sales provinces. It is not appropriate for central enterprises to take charge of national food security reserves. And it is required to make a new round of reform in autonomous management right of major grain producing areas and the capacity of the state purchasing social grain reserves.

Review of Effective Convergence between China's Rural Minimum Subsistence Security System and the Development Policy of Poverty Alleviation

Based on the conclusion of the related researches on China's rural poverty alleviation policies and poverty problems,studies of Chinese scholars on the convergence between rural minimum subsistence system and the development policies of poverty alleviation are illustrated and personal understandings proposed.On the one hand,considering the actual situations of the quickening of China's urbanization and deepening of poverty,it is necessary to make significant adjustment and transformation in China's poverty reduction policies and minimum subsistence security system.On the other hand,it is pointed out that there is no omnipotent experience to follow in the convergence of minimum subsistence security system and poverty reduction policies.The actual conditions in various regions should be taken into consideration.And it is suggested that China should achieve the organic integration of rural minimum subsistence security system and poverty alleviation policies from management,capital and policy.

Ethnic Issues of China's Neighboring Countries and Their Impact on National Security

In the international community,the internal ethnic issues of one country can easily spread out of its borders through the impact of internal and external factors to affect the national security of other countries,known as the spillover effect.Presently,the ethnic issues of China's neighboring countries that have real consequences on the country's national security break down mainly into four types:the internal ethnic conflict,the transnational ethnic issue,the issues related with immigrants and the collaboration of the Three Forces.The risk of spillover can be summed up according to the intensity of its effect in five categories:infiltration,springboard,spillover,immigration and harassment.As diverse ethnic issues of the neighboring countries have different effects on China's national security,the Chinese government must grasp the core element of each issue to formulate specific policies.

Accelerate China's Social Security Legislation

Since the financial crisis in Asia in 1997, China's social security system has undergone continual reform and readjustment, and has proved to be an integral part of government efforts to perfect the socialist market economy as well as in building a socialist harmonious society. Although social security construction has achieved certain results, it has also left a lot of problems. With the rapid growth of China's economy and revenue, people from all walks of life are putting ever-increasing demands on the social security system; therefore, the construction of a sound social security system suited to China's current situation still remains an arduous task. In this article, the author have reviewed the 10 years development of China's social security system, analyzed problems and challenges and proposed its suggestions.

Repositioning fertilizer manufacturing subsidies for improving food security and reducing greenhouse gas emissions in China

China removed fertilizer manufacturing subsidies from 2015 to 2018 to bolster market-oriented reforms and foster environmentally sustainable practices.However,the impact of this policy reform on food security and the environment remains inadequately evaluated.Moreover,although green and low-carbon technologies offer environmental advantages,their widespread adoption is hindered by prohibitively high costs.This study analyzes the impact of removing fertilizer manufacturing subsidies and explores the potential feasibility of redirecting fertilizer manufacturing subsidies to invest in the diffusion of these technologies.Utilizing the China Agricultural University Agri-food Systems model,we analyzed the potential for achieving mutually beneficial outcomes regarding food security and environmental sustainability.The findings indicate that removing fertilizer manufacturing subsidies has reduced greenhouse gas(GHG)emissions from agricultural activities by 3.88 million metric tons,with minimal impact on food production.Redirecting fertilizer manufacturing subsidies to invest in green and low-carbon technologies,including slow and controlled-release fertilizer,organic-inorganic compound fertilizers,and machine deep placement of fertilizer,emerges as a strategy to concurrently curtail GHG emissions,ensure food security,and secure robust economic returns.Finally,we propose a comprehensive set of government interventions,including subsidies,field guidance,and improved extension systems,to promote the widespread adoption of these technologies.
