    Population and land use outmigrations from urban to peripheral areas can result in nonfunctional unmaintained historic structures which deteriorate to the point where removal is cheaper than removal or demolition by neglect The increasing rate of neglected historic structures is a growing concern There is a need for research investigating connections between urban growth management and its effect on neglect This paper applies Newmans 2013 conceptual model of measuring neglect to Geographic Information Systems comparing rates of neglect in historic Doylestown Quakertown and Bristol boroughs

    Traditional farming practice of rice field co-culture is a time-tested example of sustainable agriculture, which increases food productivity of arable land with few adverse environmental impacts. However, the small-scale farming practice needs to be adjusted for modern agricultural production. Screening of rice field co-culture farming models is important in deciding the suitable model for industry-wide promotion. In this study, we aim to find the optimal rice field co-culture farming models for large-scale application, based on the notion of food productivity.

    To achieve sustainable rural development, it is necessary to simultaneously protect ecologically important land and efficiently use existing agricultural land. Land use functions (LUFs) are widely used to assess regional sustainable development. Guyuan is located in a typical hilly and gully region of western China, with ecologically fragile land. Rural land transfer (RLT) has been advocated to prevent abandonment of agricultural land and promote rational, effective utilization of the land.

    Urbanization brings significant changes to the urban food system. There is growing attention to food self-sufficiency in metropolitan areas for the concern of greenhouse gas (GHG) mitigation in food transportation. In China, grain self-sufficiency in metropolitan areas is also an important issue for grain security and involves coordination among contradictory policy goals. Based upon a comprehensive statistical analysis of 70 metropolitan areas in mainland China, we investigated the regional differences in the trends of grain self-sufficiency capacity in these areas from 1990 to 2015.

    Food security is the basis of social stability and development. Maintaining sufficient amounts of arable land is essential for China’s food security. In this paper, we consider the relationship between arable land demand to grain demand and production capacity. The changes in national population, grain production, and consumption from 2000 to 2015 are analyzed. Then, we forecast the respective possible changes in the future and accordingly forecast the arable land demand in different possible situations.

    Modeling land use and land cover (LULC) change is important for understanding its spatiotemporal trends and plays a crucial role in land use planning and natural resources management. To this end, this study assessed the spatiotemporal characteristics of the LULC changes in Urumqi city between 1980 and 2020. In addition, future LULC was successfully projected for 2030 and 2050 under different scenarios based on the FLUS model. This model was validated using actual and simulated land use data for 2020.

    As the most intuitive manifestation of land use/land cover change, the spatio-temporal evolution of landscape patterns has significant implications for optimizing regional landscape pattern and land use management. Based on multi-period remote sensing data, we selected an optimal scale (570 m) and used the geographic detector model to analyze the spatio-temporal changes in the landscape pattern of a typical hilly area (Yujiang District, Yingtan City, Jiangxi Province) in southern China.
