“…The SNH and PRD were particularly notable for having experienced an alarming drop in agricultural land coverage; more than 8% of cropland in these areas was converted into urban land use. The evaluated results were reliable because they were similar to those in Tan et al [16] and Liang et al [17]. In addition, compared with other studies [43][44][45], we also found the urbanization-related agricultural land loss in China to be much more serious than that of other countries.…”

China's rapid urbanization has contributed to a massive agricultural land loss that could threaten its food security. Timely and accurate mapping of urban expansion and urbanization-related agricultural land loss can provide viable measures to be taken for urban planning and agricultural land protection. In this study, urban expansion in China from 2001 to 2013 was mapped using the nighttime stable light (NSL), normalized difference vegetation index (NDVI), and water body data. Urbanization-related agricultural land loss during this time period was then evaluated at national, regional, and metropolitan scales by integrating multiple sources of geographic data. The results revealed that China's total urban area increased from 31,076 km 2 in 2001 to 80,887 km 2 in 2013, with an average annual growth rate of 13.36%. This widespread urban expansion consumed 33,080 km 2 of agricultural land during this period. At a regional scale, the eastern region lost 18,542 km 2 or 1.2% of its total agricultural land area. At a metropolitan scale, the Shanghai-Nanjing-Hangzhou (SNH) and Pearl River Delta (PRD) areas underwent high levels of agricultural land loss with a decrease of 6.12% (4728 km 2 ) and 6.05% (2702 km 2 ) of their total agricultural land areas, respectively. Special attention should be paid to the PRD, with a decline of 13.30% (1843 km 2 ) of its cropland. Effective policies and strategies should be implemented to mitigate urbanization-related agricultural land loss in the context of China's rapid urbanization.

“…The second consideration is dry matter accumulation in rice, dry matter accumulation is related to the growth and development of rice, and we suggest that a suitable application rate should ensure good growth and development of rice, which proves that the amendment can alleviate the toxicity of heavy metals and also show that the amendment itself has no significant inhibitory effect on plant growth. In addition, in China, rice is an important food crop (Che et al 2015), and farmland is very scarce Liang et al 2015). Even though the rice fields are slightly polluted, agricultural production is still being carried out ; therefore, the guarantee of rice growth by the amendment can achieve better ecological, social, and economic benefits.…”

The Effect of Labor Migration on Farmers’ Cultivated Land Quality Protection

Since the reform and opening up, a large proportion of the Chinese rural labor force has transferred to urban and non-agricultural industries. Rural labor transfer not only changes the allocation of household labor in agricultural and non-agricultural sectors but also affects the utilization of other agricultural production factors. Based on data from 818 households in three counties in northern Jiangsu province, this paper analyzed the impact of labor migration on farmers' adoption of cultivated land quality protection (CLQP) behaviors. The survey results showed that farmers' awareness of CLQP was still very weak, and the proportion of farmers adopting measures such as subsoiling, straw application, cover crops and green manures and the complementary use of organic fertilizers was still relatively low. The empirical results showed that perennial out-migration for work can constrain households' protective inputs into soil conservation, but part-time farming locally can promote households' inputs. The results also showed that farmer characteristics, farming conditions and external environment also significantly affected the farmers' adoption of soil conservation practices. According to these conclusions, this paper puts forward the corresponding policy implications.
