    Land use change (LUC) is the most dynamic force in terrestrial carbon stock change, and it is imperative to account for the dynamics of LUC in carbon stock change when forming land use policies. This paper explored the impacts of LUCs on carbon (C) stocks at a county scale and detected changes of soil C stocks within a county-scale land use planning policy. The LUCs within 1979–2006 in Fuyang County (eastern China) and Fuyang Land Use Master Planning (FLUMP) (2006–2020) were selected for this pilot study.

    China has been through a period of remarkable urban sprawl since the reform and opening-up policy in 1978, with the highest urbanization occurring in the coastal zones. Sustainable urban development requires a better understanding of the spatiotemporal characteristics of urbanization. This study systematically explored urban sprawl in Chinese coastal cities with a visual interpretation method from 1979 to 2013.

    A large amount of cultivated lands in China is occupied by vacant residential areas, thereby wasting land resources and placing local food security at risk. Therefore, transforming vacant rural residential land back to its previous form is urgently required to maintain the amount of cultivated land and guarantee food security.

    Due to the multiple impacts of landform effects, spatial heterogeneity and land use policies, farmland dynamics in mountainous areas are complicated. This study investigated farmland dynamics based on land use data from a typical mountainous area, Panxi, in China for 1990, 2000 and 2010, discussed the relationship between altitude, slope and farmland changes and presented an analysis of the driving forces of farmland change. Our findings are as follows: (1) from 1990 to 2010, the area of converted farmland was relatively small (313 km2), accounting for only 2.6% of the region’s farmland.

    Forests are under pressure from land use change due to anthropogenic activities. Land use change and harvest are the main disturbances of forest landscape changes. Few studies have focused on the relative contributions of different disturbances. In this study, we used the CA-Markov model, a land-use change model, coupled with a forest landscape model, LANDIS-II, to simulate dynamic change in Taihe County, China, from 2010 to 2050. Scenarios analysis was conducted to quantify the relative contributions of land use change and harvest.

    When developing land to meet various human needs, conducting assessments of different alternatives regarding their sustainability is critical. Among different alternatives of land-use, devoting land to bioenergy is relatively novel, in high demand, and important for addressing the energy crisis and mitigating carbon emissions. Furthermore, the competition and disputes among limited land-use for bioenergy and the combination of food production and housing are tense. Thus, which alternative of land-use is more sustainable is an important question, yet it is still under-investigated.

    In Hong Kong, reclamation is the main method for developing new land use areas as most country parks and mountains are protected under a land policy that emphasizes conservation for their high ecological value. Therefore, the land use for urbanized area in Hong Kong is limited, which has become an issue of concern. Hong Kong’s population is increasing; however, the amount of available land use is insufficient to meet the demand. Developing a high density of buildings is one of the critical strategies of Hong Kong’s government.

    Improving agricultural production efficiency is an effective means to ensure food security and promote agricultural sustainable development in China. Stable agricultural land property rights help optimize the allocation of production factors and improve production efficiency, and it is of great practical significance to study the influence of farmland tenure security on agricultural production efficiency.

    A stable farmland tenure can optimize farmers’ allocation of production factors and then determine the income level and structure of farmers. In recent years, the reform of China’s farmland tenure system had been making efforts to strengthen the stability of farmland tenures. Will the farmland tenure security restrict agricultural development? Based on the data of the 2018 China Labor Dynamics Survey (CLDS), this paper empirically analyzes the impact of farmland tenure stability on rural household income and its mechanism.

    Land fragmentation and the small size of land parcels are still the major bottlenecks for agriculture sustainable development in rural China, and an efficient land rental market could consolidate land plots and realize agricultural management at a moderate scale. However, transaction cost is still the main obstacle of land transfer. It is, therefore, essential to reduce the excessive transaction costs in the process of transfer; the primary task is to identify the roots of transaction costs.
