“…Simultaneously, the Chinese Government has successively issued notices on handling land violation cases and prohibiting cultivated land abandonment in development zones and urban construction. After that, the necessary regulations on cultivated land protection were formed in 1994, and a preliminary idea of the dynamic balance of total cultivated land was proposed in 1996 (Li, 2019; Wu, Shan, Guo, & Peng, 2017). On this basis, the connotation, policies, and regulations of China's cultivated land protection are becoming more and more perfected.…”

Cultivated land protection is related to food security and sustainable development. As an important reserve resource, the protection and development of cultivated land in mountainous areas need attention from governments and academia. This paper analyses the long‐term evolution process cultivated land in mountainous areas of Southwest China by using large‐scale remote sensing, topographic relief amplitude model, and a modified binary logistic regression model, to understand internal reasons for evolution differentiation at the macro level. The results show that untransformed cultivated land is mainly distributed below the topographic relief amplitude of 770 m. The transformation direction and spatial characteristics of transformed cultivated land gradually shift to low relief amplitude (<631 m) areas with time. Construction land accounts for 51.11% of the cultivated land transformation, usually distributed in flatlands or basins below the relief amplitude of 498 m, and hilly cultivated land around it displays a fluctuating recovery process. Topography is the most important factor affecting the evolution of cultivated land in mountainous areas. However, there are still differences in the driving mechanism of cultivated land evolution types, and some key policies in China in the past directly affected the evolution paths of cultivated land in mountainous areas. The research results can provide ideas for the utilization and protection of cultivated land in similar mountainous areas.

“…Subiyanto and Fadilla [56] analyzed urban expansion in Indonesia and reported an increase in urban areas between 2005 and 2017, while farmland, grassland, and wetlands declined. Li [57] assessed regulations for farmland conservation in China. Although it could not provide direct evidence, the study reported that farmland increased during the study period, but forest area decreased.…”

The analysis of the local regulation effects is required for sustainable and effective land utilization because land use/land cover (LULC) changes are not only determined by human activity but are also affected by national policy and regulation; however, previous studies for land use/land cover (LULC) have mainly been conducted on the LULC changes using past experience. This study, therefore, analyzed the effects of local regulations aimed at preserving the water quality in South Korea. To this end, changes in LULC were simulated using the CA-Markov model under conditions in which two local regulations, the special countermeasure area (SCA) and total maximum daily load (TMDL), were not applied and examined the differences between the simulated LULC and the actual LULC as of 2018. In addition, the differences in the generation of pollutant loads were driven for Biochemical Oxygen Demand (BOD), Total Nitrogen (TN), and Total Phosphorus (TP) using pollutant unit-load. As a result, without SCA, the agricultural area increased by 379.0 km2, the urban area decreased by 101.8 km2, and the meadow area decreased by 176.0 km2. In addition, without TMDL, the urban area increased by 169.2 km2 and the meadow area decreased to 158.8 km2.Differences in BOD, TN, and TP pollution loads without SCA applications were shown to decrease to 22,710.5 kg·km−2 day−1, 1133.9 kg·km−2 day−1, and 429.8 kg·km−2 day−1, respectively, while BOD, TN, and TP pollution loads without TMDL applications decreased to 14,435.7 kg·km−2 day−1, 2543.6 kg·km−2 day−1, and 368.2 kg·km−2 day−1, respectively. As such, this study presents a methodology for analyzing the effects of local regulations using the CA-Markov model, which can intuitively and efficiently examine the effects of regulations by predicting LULC changes.

“…However, considering quick farmland loss during recent decades due to urban sprawl and very limited lands suitable for expanding the farmland area, more strict protection of the current farmland is still very necessary. To this end, the Chinese government has implemented several policy measures to strictly control the farmland occupation of non-agricultural construction, and to regulate the farmland protection and ecological restoration [40,41].…”

The Huangshui River Basin (HRB) is the main grain production and key implementation region of the “Grain for Green Program” (GGP) of Qinghai Province, and has experienced a quick urbanization during the last 20 years. Therefore, identifying the farmland change and its ecological effects is significant for farmland and ecological protection in the HRB. To this end, this study analyzed the farmland change between 2000 and 2018, based on 1 m spatial resolution farmland data visually interpreted from Google Earth high-resolution images, and then estimated its ecological impact based on the Normalized Difference Vegetation Index (NDVI) data of MODIS, using an ecological impact index of farmland change. The study found that: (1) The farmland area in the HRB decreased from 320.15 k ha in 2000 to 245.01 k ha in 2018, reduced by 23.47% or 1.48% per year, as mainly caused by ecological restoration and built-up land occupation; (2) from 2000 to 2018, the natural environment showed a greening trend in the HRB, with the mean NDVI increasing by 0.74% per year; (3) the farmland changes had a positive ecological effect, contributing 6.67% to the regional increase in the NDVI, but had a negative impact on grain production; (4) it is suggested to strengthen farmland protection by strictly controlling the urban land occupation and over-conversion of farmland in the HRB.
