Data-driven spatial modeling of historic and future land change at global scale
Assessing the historic and future impacts of land-use and land-cover change (LULCC) on climate requires spatially and temporally explicit data sets on LULCC spanning several decades to centuries, because climate change is a long-term problem. Though remote sensing data provides a globally …

Simulating Urban Landscape Transformation: Implications for Urban Wetlands at Multiple Scales
Urban landscape change simulation has received increasing attention in recent times. As a result, many studies have focused on various aspects of land change simulation, ranging from uncertainty of input data to model accuracy. While efforts have been put into improving many of the existing urban …

Dynamics and drivers of land use land cover changes in Bangladesh
Land is scarce in Bangladesh: Bangladesh occupies ~0.03 % of world’s land area, but supports over ~2% of human population. This high population to land ratio, combined with socioeconomic development has placed tremendous pressure on Bangladesh’s land resources for food, feed, and fuel. This study …

Automatic land-cover-classification derived from high-resolution Ikonos satellite image in the urban atlantic forest in Rio de Janeiro, Brasil by means of an objects-oriented approach
The city of Rio de Janeiro carried out a Land-cover forest classification with visual interpretation using SPOT data. This work produced a compatible thematic map in the scale 1:50,000. The scale of these maps permit to have a global vision of the land change cover but unfortunately do not …

Linking Streamflow Trends with Land Cover Change in a Southern US Water Tower
… (SA) region of the U.S. The forested uplands of the SA receive high amounts of rain and act as a "water tower" for the surrounding lowland area, both of which have experienced higher than average population growth and urban development. For the total of 127 USGS gages with continuous …

Hydrological responses to the synergistic changes in climate and land cover in the alpine pastoral region
Quantifying the hydrological responses to climate change and land use and land cover (LULC) change is imperative for sustainable river basin management. In this study, hydrological regimes of the upper Lancang River Basin under environmental changes are assessed using a semi-distributed hydrologic …
