United States Land Cover Land Use Change, Albedo and Radiative Forcing: Past and Potential Climate Implications
<p>Land Cover Land Use (LCLU) change affects Earth surface properties including albedo that impose a radiative forcing on the climate. Recent spatially explicit satellite derived contemporary LCLU, albedo, and projected LCLU data are used to study the impact of LCLU change from 1973 to 2000, and …

Forest fragmentation mapping, change detection, and gas well site identification in remotely sensed imagery: the role of spatial resolution
This research focuses on identifying optimal data and methods for detecting and quantifying land cover/land use change associated with natural gas drilling in Appalachia. Airborne and satellite remote sensing provides a tool for examining land cover changes. Although change detection has been used …

A Spatial and Multivariate Approach to Examining Effects of Urbanization on Nitrogen Sources, Organic Matter Inputs, and Trophic Structure in Streams of Cobb and Paulding Counties, Georgia.
<p>Urbanization and land use changes have a negative effect on streams often causing numerous physical changes in stream morphology, a change in nutrient concentrations, and altered ecosystems contributing to a loss of habitat, decreased biodiversity, and loss of stability for ecosystem function …

Identification des facteurs environnementaux responsables de la présence de Campylobacter Jéjuni dans les eaux de surface de l'Estrie (Québec)
… 10 of them were excluded from the analysis, because their hydrographic basin was not independent from the other sites. For each site, the following environmental variables were included: Water flow, slope, land-cover, land-use including type of farming, animal density, total precipitation in the …

Spatial and Temporal Distribution of Groundwater Recharge in the West Bank Using Remote Sensing and GIS Techniques
… temporal distribution of recharge. The approach used in this research integrates data derived from satellite images (e.g. land cover, evapotranspiration, rainfall, and digital elevation model) with hydrogeological data in a Geographic Information System (GIS) model to identify and map the surface …
