“…Food security is a multidimensional security goal and is affected by many factors, among which food production is the most critical link in the food security system [ 96 , 97 , 98 ]. Land use change affects regional food production through changes in area and spatial location among different land use types, and temporal and spatial changes in cultivated land are one of the main forms of land use change [ 99 ], which affects the global food security supply [ 100 ]. At present, the research focus of most scholars is on quantifying the impact of cultivated land change on food security.…”

Many scholars have conducted in-depth research on the theme of land use change and food security, and formed fruitful research results, but there is a lack of quantitative analysis and comprehensive evaluation of research achievements. Therefore, based on the relevant literature on the theme of land use change and food security in the core collection of the Web of Science (WOS) database, this paper takes the advantage of CiteSpace and VOSviewer bibliometric software to draw the cooperative network and keyword cooccurrence map to analyze the research progress and frontier. The results reveal that: (1) The research started in 1999 and can be divided into three stages: initial research, rapid development, and a stable in-depth stage. This topic has increasingly become a research hotspot in the academic community. (2) The distribution of research institutions is concentrated and forms a small cluster, and the research networks between developed and developing countries have been established, and developed countries are in the core position, but the cooperation network is not prominent. (3) The research content is becoming increasingly organized and systematic, and the research hot topics are divided into seven aspects. (4) The research area of the subject covers multiple levels, such as global, national, and specific natural geographical regions, and has formed a research system of geographic information technology and satellite remote sensing technology. It also presents the trend of cross integration with economics, land management and soil science. In the future, theoretical innovation still needs to be strengthened, and we should strengthen the research on the impact of agricultural chemical fertilizers on food security and study the impact of urban expansion on land use change.

“…With the acceleration of urbanization, urban agglomeration has gradually become an important development model, and more and more scholars have studied the sustainable development of a certain region or urban agglomeration (Tan et al, 202;Zinatizadeh et al, 2017), mainly focusing on China's Yangtze River Delta urban agglomeration (Huang et al, 2020), Beijing-Tianjin-Hebei urban agglomeration (Chen et al, 2019), Chengdu-Chongqing urban agglomeration (Cheng et al, 2020), the Yangtze River urban agglomeration (Gu et al, 2015;Luo et al, 2021), etc. In addition, in recent years, research on the sustainable development of foreign urban agglomerations has gradually emerged (Butsch et al, 2017).…”

In the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), a series of natural environmental, economic, and social issues have emerged sequentially in the process of rapid economic and social development. Therefore, for the sustainable development of the GBA, how to closely integrate nature protection with economic and social development to improve the sustainable development level of the social-economic-natural compound ecosystem, and realize the coordinated development of the system is particularly important. Based on the perspective of complex network and the theory of compound ecosystem, this study proposes a set of sustainable development evaluation model based on complex network modeling to evaluate the sustainable development level of compound ecosystem in GBA from 2014 to 2018, and further analyze the coupling coordination degree. The major findings include: 1) For the sustainable development in the GBA, the development of the natural subsystem is an important foundation, and the synchronous development of the social and economic subsystems are the main driving force. 2) The sustainable development level in the GBA shows an overall steady upward trend; the average level of the compound ecosystem’s coupling coordination development is in a “good” state, and it shows an evident upward trend. 3) Whether it is within the GBA or the GBA and its surrounding regions, there are problems of unbalanced and insufficient regional development. Policy recommendations include increasing the emphasis on the sustainable development of the natural subsystem, promoting the coordinated development of the economic, social, and natural subsystems, and promoting the balanced development of cities within the GBA, as well as the GBA and surrounding regions.

“…YREB, as one of the most important grain yield bases, also has 3.08 × 10 7 ha of cropland, which contributes to 32.5% of grain yield, reflecting active agricultural activities. Therefore, frequent cropland transitions have been observed by recent studies (Cheng et al, 2020;Tang et al, 2021;Yang et al, 2021). With the exception of spontaneous cropland expansion activities, there are also some cropland expansion activities implemented under policy requirements, among which the Cropland Balance Policy is the most targeted policy (Song and Pijanowski, 2013;Liu et al, 2017).…”

“…Topographic factors, such as water and heat, can highly influence the spatial distribution of cropland and its expansion by affecting the distribution of farming conditions (Gao et al, 2019), thereby affecting the spatial distribution of different cropland expansion trajectories. The majority of the existing studies have explored the influence of DEM on cropland (Cheng et al, 2020;Folberth et al, 2020), and have disregarded the difference between the surface of relief amplitudes in different levels of DEM. For example, a district with a low DEM may have a higher relief amplitude than a district with a high DEM, thereby having limited cropland and cropland-related activities.…”

A clear understanding of cropland expansion dynamics and their effects is vital for cropland protection and food security. However, the trajectories of cropland expansion have been less discussed. This study referred to the modes of landscape expansion and assessed the cropland expansion trajectory in three urban agglomerations in the Yangtze River Economic Belt and its impact on cropland fragmentation. Specifically, we identified three cropland expansion trajectories using the landscape expansion index, namely, infilling, edge-expansion, and outlying. Moreover, the surface relief amplitude model was employed to characterize the relief amplitude effect on cropland expansion trajectories. By coupling landscape metrics (e.g., patch density, landscape shape index, the largest patch index, and aggregation index) and Spearman correlation analysis, the relationship between cropland expansion trajectories and cropland fragmentation was assessed. Results show that (1) three urban agglomerations experience cropland expansion, in which the edge-expansion trajectory is primary, followed by infilling and outlying trajectories; (2) the cumulative frequency curve indicates that infilling and edge-expansion trajectories are likely to be distributed in low topographic relief amplitude regions, while the outlying trajectory is located in relatively higher topographic relief amplitude regions; and (3) infilling and edge-expansion trajectories contribute to a significantly positive relationship with the decrease of cropland fragmentation, while the outlying trajectory has a negative relationship with cropland fragmentation. This research highlights that cropland protection policies should considerably focus on the trajectory of cropland expansion, not only request the total area of cropland in a dynamic balance.
