urban expansion and agriculture intensification are relevant drivers in land degradation (ld)processes in europe due to net loss of land, soil sealing, landscape fragmentation and other negative effects on the environment. this paper explores changes (or “trajectories” of change) in land use and cover (lulc) and their relationship with the consumption of soils in emilia-romagna (northern italy)...

The urban clusters in the Middle Reaches of the Yangtze River (MRYR) in China include the Chang-Zhu-Tan urban agglomeration, the Wuhan metropolitan area, and the Poyang Lake urban agglomeration. While previous studies of urban expansion in China focused mainly on the coastal regions, this study aimed to investigate urban expansion patterns and factors in the MRYR, which are crucial for urban de...

Urban land has increasingly expanded and encroached upon a significant number of paddy fields in Hang-Jia-Hu Plain, due to the rapid socio-economic development and agro-pedoclimatic conditions favorable to rice cultivation and human settlement. Although many studies have analyzed the characteristics of urban land expansion, relatively less attention has been paid to exploring the various urban ...

For decades, rapid urban expansion has led to concerns over the loss of cultivated land in rural China. Less well known is the fact that development of newly cultivated land has in fact consistently exceeded land conversion from 1999-2006. This paper provides an analytical model that makes sense of this observation, featuring fiscal decentralization, local governments as custodians of land use ...

Although the mapping of spatiotemporal patterns of urban expansion has been widely studied, relatively little attention has been paid to detailed comparative studies on spatiotemporal patterns of urban growth at the regional level over a relatively longer timeframe. This paper was based on multi-sensor remote sensing image data and employs several landscape metrics and the centroid shift model ...

The SLEUTH model, based on the Cellular Automata (CA), can be applied to city development simulation in metropolitan areas. In this study the SLEUTH model was used to model the urban expansion and predict the future possible behavior of the urban growth in Tehran. The fundamental data were five Landsat TM and ETM images of 1988, 1992, 1998, 2001 and 2010. Three scenarios were designed to simula...

Urban expansion is the outcome of intensive human activity within a certain natural environment and may cause ecological and environmental problems, especially on small islands where land is a scarce resource. Praia is the capital city of Cape Verde, located on such an island. Understanding urban expansion will provide good knowledge for urban planning and policy making in balancing urban econo...

Urbanization is found to be closely associated with land use/land cover change which has an important influence in our environment and ecosystems, such as urban heat island effect, biodiversity loss, soil erosion, and pollutions. Studies on accurately simulating urban expansion have been inspired by increasing concerns of the sustainability of urban development. This paper reports our research ...

studies relating form and functions of cities indicate sprawl as an intriguing research issue, especially for certain typologies of cities. although with inherent differences on a local scale, mediterranean cities offer a kaleidoscopic overview of sprawl morphologies that require dedicated monitoring tools. the present study provides an original assessment of recent urbanization processes in th...
