Abstract
Land is a main factor in food production, and cultivated land resources provide opportunity for the national food security. This study empirically estimates the impact of farmland protection on the security of grain supply in major grain-producing areas of China. For this purpose, from 2010 to 2019, panel data was collected from 13 main grain-producing provinces of China. The results revealed that the protection of cultivated land resources in the main grain-producing areas with direct means, incentives, and technological progress, significantly and positively impacted the security of grain supply. Furthermore, a mismatch was found between resource conditions and their use for grain production in the Northern region, and the lack of protection of cultivated land resources in the Southern region, which leads to the insignificant positive promotion of grain supply security. The results of the study strongly suggest that central and national governments of China need to provide a proper policy for the protection of cultivated land resources with equal emphasis on quantity, quality, and sustainability to ensure food security.
Highlights
China focuses on massive agricultural production, food security is still a threat because of its growing population due to the three-child policy [1]
As for the control variables, the standard deviation of the cropping index and the proportion of people employed in primary industry was small, and the standard deviation of per capita land operation scale and agricultural water consumption was large, indicating that there was little variation in natural water and heat conditions and the proportion of people engaged in agriculture in the major grain-producing areas from 2010 to 2019, but there was a big difference in land concentration and agricultural water consumption
The aim of this study was to evaluate the impact of farmland protection on security of grain supply in the major grain-producing areas of China
Summary
China focuses on massive agricultural production, food security is still a threat because of its growing population due to the three-child policy [1]. 2009, about 3 million hm of high-quality cultivated land was converted into construction land in China [2]. The soil fertility of this part of the cultivated land foundation was relatively poor (Data sources: Bulletin of national cultivated land quality grade in 2019). China is focusing on the protection of cultivated land resources as a basic national policy. The main grain-producing areas in China have been contributing 75% of the national grain output and 80% of commodity grain [3]. The grain-producing areas have an important role to ensure food security.
