The rapid economic development resulting from Chinese economic reform has greatly accelerated urbanization and industrialization, thus leading to alterations in the natural landscape. Understanding the extent of these changes is important for regional sustainable land management. An integrated approach with a geographic information system and remote sensing was used to extract land use/land cov...

A unique model of resources consumption drag of urbanization is developed by employing the neo-classical production model and the urbanization relation model. By using this model, it is viable to estimate the resources consumption drag, measured as the reduced speed of urbanization from resources consumption and environmental services. In terms of reduced urbanization process, the aggregated an...

Dhaka is one of the fastest growing megacities of the world with a dense population over 15 million. Being the capital of a developing country like Bangladesh, it is experiencing multi-dimensional problems such as over urbanization, traffic congestion, water logging, solid waste disposal, black smoke from brick kilns and industrial emissions, sound pollution, pollution of water bodies by indust...

Urban areas account for more than 70% of CO2 emissions from burning fossil fuels. Urban expansion in tropics is responsible for 5% of the annual emissions from land use change. Here, I show that the effect of urbanization on the global carbon cycle extends beyond these emissions. I quantify the contribution of urbanization to the major carbon fluxes and pools globally and identify gaps crucial ...

The term “physical development and land use” was primarily raised in the Western countries so that governments could monitor the way the land is used and to maintain property rights. However, with rapid growth of urbanization and development of urban and regional planning the dimensions and the contents of the concept have expanded day by day. The central and practical core of urban planning is...

China is undergoing rapid urbanization during the past decades. For example, the proportion of urban population in Beijing has increased from 57.6 % in 1980 to 86.3 % in 2013. Rapid urbanization has an adverse impact on the urban rainfall-runoff processes, which may result in the increase of urban flood risk. In the present study, the major purpose is to investigate the impact of land use/cover...

There has been worldwide concern for sustainable development especially after the 1992’s Rio’s UN Conference on Environment and Development. Rapid encroachment of urban development on valuable agricultural land will have great in ̄ uence on whether sustainable development can be achieved. A sustainable land development model is developed using GIS in an attempt to control urban sprawl under rapi...

Applied with remote sensing, GIS, and mathematical statistics, the spatial-temporal evolution characteristics of urbanization expansion of Yantai city from 1974 to 2009 was studied. Based on landscape pattern metrics and ecological risk index, the landscape ecological risk from the landscape pattern dynamics was evaluated. The results showed that the area of urban land increased by 189.77 km(2)...

This study explores an approach of combining remote sensing and a spatial metric to characterize land use change in Hanoi, Vietnam. The work is based on the land cover information of 4 different times derived from Landsat and ASTER data from 1975 to 2003. This study adopted the spatial metrics; the percentage of like adjacency (PLADJ), which calculates the number of like adjacencies involving t...

this study examines the relationship between land use/land cover (lulc) changes and surface runoff generation empirically to reveal how urbanization has altered the hydrologic characteristics of a watershed. a hydrological model, the soil and water assessment tool (swat), is employed to estimate the watershed runoff generation for two lulc scenarios from 2002 to 2010. the cypress creek watershe...
