“…Therefore, we suggest that the project development should be carried out according to local conditions, combined with regional characteristics, paying more attention to the quality development and protection of basic farmland, and improving grain production. Additionally, we should consider the successes of existing research at home and abroad [15][16][17][18][19][20] and investigate the confirmation of land rights, land quality registration, accurate recording of land categories, remote sensing monitoring and other work, so as to comprehensively ensure the achievement of high-standard farmland development.…”

“…Boztoprak et al found that the registration of the location, quantity and quality of agricultural land could effectively solve the problems of rural land in land consolidation projects, yet more precise land categories were still needed [15][16][17]. Some other scholars also carried out research that monitored and evaluated the use of agricultural land [18][19][20] and found that the rational use of land is of great significance to the improvement of crop yield and the ecological environment.…”

In 2013, the government officially approved the construction task of developing high-standard farmland, which had been written into the outline of the “12th Five-Year Plan”, the “13th Five-Year Plan” and the “14th Five-Year Plan”, effectively ensuring the sustainable development of farmland with high and stable yield in China. Moreover, with the rapid progress of urbanization and industrialization, the quality and usage of cultivated land have changed greatly, and the relationship between the economic value, social value and ecological value of land has become increasingly prominent. Whether the development of high-standard farmland, especially the high-standard farmland used for grain production, has achieved the goals of increasing farmers’ income, agricultural output and rural development is not clear. Therefore, it is necessary to evaluate the comprehensive benefits of high-standard farmland development in grain production, so as to scientifically measure the results of the development. From the perspective of economic, social and ecological benefits, this paper establishes an entropy weight evaluation index system and a model to evaluate the level and effectiveness of high-standard farmland development from 2013 to 2020 in China. The results show that the high-standard farmland development project has improved the yield of grain and the basic productivity of cultivated land, effectively increased the yields of land in the project area and promoted the protection and improvement of cultivated land quality, which includes soil quality improvement, soil fertility enhancement, pollution control and soil remediation. The project also helped raise the farmers’ income levels and improved farmers’ agricultural knowledge and skills in the project area. The projects are very beneficial for agricultural production, the farmers’ income and rural development. However, there is still a certain gap between the national average level of improvement and the original goal set in the policy. The average grain yield per mu (Note: 1 mu ≈ 0.0667 ha, similarly hereinafter) was expected to be increased by less than 100 kg (the national average was a 40 kg increase), and the degrees of improvement in economic, social, ecological and comprehensive benefits in different project types were also different. In the future, we suggest that the project should be implemented according to local conditions and the features of each region. We should pay attention to the protection of basic farmland quality and further improve grain output to achieve the goal of stabilizing and increasing production.

“…Zhang et al used Google Earth Engine to analyze the environmental changes caused by the consolidation of farmland in the study area, and the results showed that farmland consolidation may have a short-term negative impact on the environment, and the positive effect will appear after more than 3 years, and relevant government policies may also have an impact [13]. Luo et al used satellite data to detect the change in the area of abandoned farmland in the study area from 2015 to 2019 to assess the impact of policies on abandoned farmland, and the results showed that more policies are not necessarily effective, and that attention should be paid to the scientific basis of policies [14].…”

Agricultural land protection in China: current status and historical background

Agriculture has always been central to China's cultural and economic development. The traditional calendar used in China to this day tells villagers the best time to sow and harvest, further confirming the importance of agriculture in everyday life. Land has always been the backbone of the agricultural sector, which in turn is the cornerstone of China's economy. Over the years, they have ensured national food security and provided livelihoods for large populations. Although the total amount of agricultural land in China is the third largest in the world, for a large area of land, only 0.106 hectares per capita is accounted for, which is far below the world average. Given the pressures of shrinking agricultural land due to economic development, rapid population growth, and urban growth, the Chinese government has developed a series of measures to protect agricultural land and ensure food security. This article is aimed at a detailed analysis of the evolution of agricultural land protection policy in China, an attempt to analyze the reasons for policy change, the measures introduced and their effectiveness. It will also provide experience and inspiration for solving issues related to land resources in Ukraine and can become the basis for cooperation between China and Ukraine in the field of agriculture to jointly address the global challenges of food security.

“…The results of the study highlighted that the mapping accuracy of abandoned cropland is significantly influenced by the quality of the data retrieved from the selected samples. The current methods of sample collection may not keep pace with the rapidly evolving requirements of monitoring, and this especially becomes an issue when considering large areas [46]. This challenge underscores the need for more diversified and rapid sample collection strategies to enhance monitoring efficiency and accuracy.…”

Whether China can achieve the United Nations’ Sustainable Development Goals (SDGs) largely depends on the ability of main food-producing areas to cope with multiple land use change challenges. Despite the fact that the Yangtze River basin is one of the key regions for China’s food security, the spatiotemporal dynamics of cropland abandonment and recultivation remain largely unexplored in this region. The present study assesses the evolution of the agricultural system within the Yangtze River basin between 2000 and 2020 by mapping cropland abandonment and recultivation using MODIS time series and multiple land cover products. The results highlight a widespread cropland abandonment process (i.e., 10.5% of the total study area between 2000 and 2020), predominantly in Western Sichuan, Eastern Yunnan, and Central Jiangxi. Although 70% of abandoned cropland is situated in areas with slopes less than 5°, the highest rates of abandonment are in mountainous regions. However, by 2020, 74% of this abandoned cropland had been recultivated at least once, whereas half of the abandoned croplands got recultivated within three years of their initial abandonment. Hence, as this is one of the first studies that unravels the complex interaction between cropland abandonment and recultivation in a spatiotemporal explicit context, it offers (i) scientists a novel methodological framework to assess agricultural land use issues across large geographical entities, and (ii) policy-makers new insights to support the sustainable transition of the agricultural sector.
