To date, human activities have been the primary source of landuse and land cover changes; however, climate change is expected to exacerbate and accelerate impacts on terrestrial, hydrological and climatic regimes, as well as increase the vulnerability of species (Theme 5) and cultural (Theme 6) resources (Staudinger et al., 2012; Staud et al ...
land use. • Independent of legend required by different stakeholders. It would be possible to aggregate data on different scales and mapping units. • Able to facilitate analysis of impact of different economic activities as well as impact of nature''s vagaries on areas under land and water.
Emerging evidence shows that the boundaries of protected areas (PAs) and their level of protection regularly change, yet little is known regarding the underlying causes of these legal changes and their impacts on ecosystems. For PA degazettements (, protection removals) in the state of Rondônia in the Brazilian Amazon we show that the PAs less effective in stemming deforestation are more ...
Introduction. In addition to emissions of heattrapping greenhouse gases from energy, industrial, agricultural, and other activities, humans also affect climate through changes in land use (activities taking place on land, like growing food, cutting trees, or building cities) and land cover (the physical characteristics of the land surface, including grain crops, trees, or concrete). 10 For ...

Land use/land cover (LU/LC) changes were determined in an urban area, Tirupati, from 1976 to 2003 by using Geographical Information Systems (GISs) and remote sensing technology. These studies were employed by using the Survey of India topographic map 57 O/6 and the remote sensing data of LISS III and PAN of IRS ID of 2003. The study area was classified into eight categories on the basis of ...
