Geospatial information systems analysis of regional environmental change along the Savannah River Basin of Georgia.
(59/299)
This paper uses remote sensing and geographic information systems (GIS); and descriptive statistics in the assessment of environmental change along the Savannah River Basin of Georgia. Results of the study show that Savannah River basin side of Georgia has been experiencing environmental change due to several decades of relentless pressure induced by anthropocentric activities and host of other socio-economic factors. Normalized Difference Vegetation Index (NDVI) analysis of the area also shows a decline in vegetation cover. The pace of ecological change showed some variations across time and space. Generally, the results point to a decline in water bodies, vegetation, and increase in population, loss of harvested cropland, farms and increasing threats to the environmental systems of the region.

Population health needs beyond ratifying the Kyoto Protocol: a look at occupational deprivation.
(61/299)
The dramatic impact of climate change is physically and economically affecting the world, a consequence of neglecting scientific information known since the 1960s and 1970s. International discussion has focused on the needs of the physical environment and general health concerns (such addressing greenhouse gas production and population health issues); however, little acknowledgement has yet been made of local human issues, such as the effect of climate change on the mental health of those in rural communities. This commentary takes an occupational science perspective to describe new ways of classifying potential mental health problems associated with climate change and its impact on the rural environment. It challenges policy makers to take a proactive approach to addressing the current impacts of climate change on the future mental health of individuals in rural communities. (+info)
