This paper reviews the cumulative effect of land-cover change on local, regional, and global weather and climate. Documented land-cover changes from 1700 to the present are shown to be particularly significant in the tropics. Model results are presented which show the teleconnection of weather patterns worldwide result from these landscape changes.
Land cover changes influence the biogeochemistry, hydrology and climate of the earth. Studies that assessed land cover changes at the global scale mostly focused on: deforestation, cropland expansion, dryland degradation, urbanisation, pasture expansion and agricultural intensification. For the assessment, remotely sensed land-cover data, census data and expert knowledge were used. In tropical ...
The objective of the European-wide programme CORINE Land Cover (CLC) is the generation and regular update of consistent and comparable information on land cover in Europe for environmental assessment and planning purposes. The project CORINE Land Cover 2000 (CLC2000) aims at the update of the land cover data base for the year 2000 and the mapping of land cover changes in Europe during the last ...
Changes in land-use systems in tropical regions, including deforestation, are a key challenge for global sustainability because of their huge impacts on green-house gas emissions, local climate and biodiversity. However, the dynamics of land-use and land-cover change in regions of frontier expansion such as the Brazilian Amazon is not yet well understood because of the complex interplay of ecol...
Changes in land-use systems in tropical regions, including deforestation, are a key challenge for global sustainability because of their huge impacts on green-house gas emissions, local climate and biodiversity. However, the dynamics of land-use and land-cover change in regions of 5 frontier expansion such as the Brazilian Amazon is not yet well understood because of the complex interplay of ec...
This study analyses the expansion of urban growth and land cover changes in five Saudi Arabian cities (Riyadh, Jeddah, Makkah, Al-Taif and the Eastern Area) using Landsat images for the 1985, 1990, 2000, 2007 and 2014 time periods. The classification was carried out using object-based image analysis (OBIA) to create land cover maps. The classified images were used to predict the land cover chan...
Geographic information systems and satellite remote sensing information are emerging technologies in land-cover change assessment. They now provide an opportunity to gain insights into land-cover change properties through the spatio-temporal data capture over several decades. The time series of Landsat images covering the 1985–2009 period is used here to explore the impacts of surface mining an...
Predicting the impact of land cover and climate change on hydrologic responses using modeling tools are essential in understanding the movement and pattern of hydrologic processes within the watershed. The paper provided potential implications of land conversions and climate change scenarios on the hydrologic processes of Muleta watershed using soil and water assessment tool model. Model inputs...
Digital change detection is the process that helps in determining the changes associated with land use and land cover properties with reference to geo-registered multi temporal remote sensing data. Puer and Simao, where land use has been greatly affected by recent government policies that aim to balance the need to encourage rural development with ecological stability. These policies include pr...
Rapid urbanization changes the land use/land cover pattern of a developing region. Due to these land surface changes, stream flow of the rivers also changes. It is important to investigate the factors affecting hydrological characteristics of the river basin for better river basin management planning. This study is aimed to understand the effect of Land Use/Land Cover (LU/LC) changes on stream ...
