Spatiotemporal Decoupling between Population and Construction Land in Urban and Rural Hubei Province
In urban and rural areas under rapid urbanization, a proper understanding of the relationship between population and construction land use is important for regional sustainable development. The decoupling method is a particularly useful way to examine this relationship. However, the decoupling method only considers the current relationship between population and construction land, ignoring the ...
Rapid urbanization and population growth in China have raised great concerns regarding food security caused by the loss of limited cultivated land. In this study, we used remotely sensed data and an agricultural productivity estimation model to characterize the spatiotemporal patterns of the conversion of cropland into urban land and quantify its impacts on agricultural productivity potential d...
Rice paddy fields provide important ecosystem services (e.g., food production, water retention, carbon sequestration) to a large population globally. However, these benefits are diminishing as a result of rapid environmental and socioeconomic transformations, characterized by population growth, urbanization, and climate change in many Asian countries. This case study examined the responses of s...
Understanding land-expropriated farmers’ welfare change and the determinants of their willingness to change is very important for sustainable urbanization and social stability in developing countries. However, this issue has been seldom explored in previous studies, especially in China. This paper aims to enrich this field by conducting an empirical study using a household survey in 2014 in Nan...
The rapid growth of the built environment has been pointed out as one of the major challenges to sustainability in the US. Low density “sprawling” neighborhoods represent the most undesired form of urban growth both for the waste of land and energy they cause, as well as for the lack of a “sense of place” they promote among their inhabitants. Several critiques to such type of urbanization have ...
2 The Asia/Pacific Research Center (A/PARC) is an important Stanford venue where faculty and students, visiting scholars, and distinguished business and government leaders meet and exchange views on contemporary Asia and U.S. involvement in the region. A/PARC research results in seminars and conferences, published studies, occasional and discussion papers, special reports, and books. A/PARC mai...
Africa has been undergoing a rapid urbanization process, which is critical to the achievement of 11th Sustainable Development Goal (SDG11). Using population density data from LandScan, we proposed density-based thresholding method generate urban land and in 2001 2019, were further applied detect spatiotemporal characteristics Africa’s urbanization. The results showed that have both grown rapidl...
Cities are rapidly growing throughout the world and are altering biologic processes in many regions, with global consequences. Urbanization in the Phoenix, USA metropolitan region has dramatically altered regional ecosystem patterns, but little is known about how these changes have influenced soil organic matter, total nitrogen, and the distribution of nitrogen stable isotopes. Because urban de...
With the rapid development of urbanization, scales urban population and land use are tremendously expanding [...]
Based on the construction of an evaluation index system for land urbanization quality, this paper evaluates and analyzes variability spatial-temporal in quality during 2005-2015 China. Results shows that: (1) Among three aspects sustainable development capacity scores highest, follows, land-population coordinated is lowest. (2) The China generally improving, spatial distribution has a "gradient...
