This study is carried out to determine land use changes by Geographic Information Systems and Remote sensing methods in Yenimahalle district of Ankara province. Changes in land use were identified between 2000-2005 and 2000-2010. For the study Landsat-5 image of year 2000, Ikonos image of year 2005, and SPOT image of year 2010 were used. 1:25000 scale topo maps and soil maps, and CORINE land use data were also used. GPS data collected from field were used for ground truth studies.

In this study, ideal but realistic numerical experiments are performed to explore the relative effects of changes in land use and emission distribution on air quality in the Pearl River Delta (PRD) region in winter. The experiments are accomplished using the Lagrangian particle transport and dispersion model FLEXPART coupled with the Weather Research and Forecasting model under different scenarios.

Regional climate is influenced by land surface processes through energy exchange between land and atmosphere at various scales. The performance of climate model simulation is largely influenced by land cover parameterization, especially over areas that experience rapid change of land surface characterization. Accurate land cover datasets suited for climate modeling are urgently needed to improve model parameterization for better simulation.

Soil contamination by heavy metals has become a widespread dangerous problem in many parts of the world, including the Mediterranean environments. This is closely related to the increase irrigation by waste waters, to the uncontrolled application of sewage sludge, industrial effluents, pesticides and fertilizers, to the rapid urbanization, to the atmospheric deposition of dust and aerosols, to the vehicular emissions and to many other negative human activities.

Outward expansion of urban lands in the developing nations is often associated with a substantial loss of environmental resources such as forests, wetlands, freshwater and cash crop fields. Yet, determining how different aspects of urbanisation – such as city population size and spread pattern of built-up lands – contribute to the cumulative loss of resources remains controversial. In this study, data sets were constructed describing changes to land cover across 65,200 grid cells at 1 km² spatial resolution for China's Changjiang Delta Region over the past 60 years.

Managing urban growth in the current rapid urbanization process has become a key issue for land use policy in transformation China. This paper maps and assesses the performance of urban containment strategies in China, looking at the case of Beijing over a 19-year period (1990–2009). The analysis shows that to a large extent containment strategies perform well in terms of concentrating urban growth in planned suburban areas and promoting compact development.

The urbanization has been significantly created wide scope of employment opportunities through manifold services sector. The mobility or migration of rural people has changed the social and economic condition of the landless labour of the rural area. In this case study migration of the village young of East Midnapore district of West Bengal who were from landless labour families with a little education has been noted. Their social and economic position had been remarkably changed within 3-5 years.

Increasing land utilization through diverse forms of human activities, such as agriculture, forestry, urban growth, and industrial development, has led to negative impacts on the water quality of rivers. To find out how catchment attributes, such as land use, hydrologic soil groups, and lithology, can affect water quality variables (Ca²⁺, Mg²⁺, Na⁺, Cl⁻, HCO₃⁻, pH, TDS, EC, SAR), a spatio-statistical approach was applied to 23 catchments in southern basins of the Caspian Sea.

In a closed landfill, we investigated the diversity and ecological characters of carabid beetles to understand the ecological importance of closed landfills that have the potential as a multi-functional habitat for improving biodiversity in urbanized areas. In addition, we studied the influence of environmental factors (vegetation structure, soil) on distribution and diversity of carabid beetles. A total of 92,495 individuals representing 15 carabid species were collected from the closed landfill.

Cities have been expanding rapidly worldwide, especially over the past few decades. Mapping the dynamic expansion of impervious surface in both space and time is essential for an improved understanding of the urbanization process, land-cover and land-use change, and their impacts on the environment. Landsat and other medium-resolution satellites provide the necessary spatial details and temporal frequency for mapping impervious surface expansion over the past four decades.

Contemporary land-use change and impacts on natural systems are of concern throughout the Cornbelt region, where agricultural activities have extensively altered the landscape. Land-use changes driven by urbanization throughout this region could have a disproportionate impact on remaining natural areas, particularly forests. We used readily available data sets and software to assess land cover change for four municipalities in Iowa and to examine the usefulness of this approach for urban foresters and planners interested in understanding/predicting impacts of land cover change.

Estuaries in the southeastern USA have experienced increased loading of contaminants from nonpoint source runoff as well as changes in habitat (e.g., loss of wetlands) due to urbanization. These changes may pose significant risks to estuarine fauna, including crustaceans. Several studies have shown relationships between land use classification and levels of stress in estuarine populations. The grass shrimp of the genus Palaemonetes is one of the dominant species found in estuarine tidal creeks, accounting for more than 50� % of all macropelagic fauna.
