DESCRIPTION:In the 1850s landscape photography proliferated in the American
  West as a means of recording “then and now” views of the same landsca
 pe after some interval of time. Many photos were casual\, usually taken fr
 om the same view point but without regard to season\, or the exactness of 
 the scene being photographed. Some are very precise and involve a careful 
 study of the original image. These photos have provided a unique database 
 that has been exploited by scientists from both universities and US enviro
 nmental agencies to track the impact of first people upon the landscape an
 d later of climate change. Pioneered in the US state of Arizona\, this tec
 hnique provided a unique opportunity to record changes in vegetation cover
  due to climate change and human impact\, and to document ongoing surficia
 l processes due to both. Remote sensing when combined with repeat photogra
 phy provides a unique opportunity to study these changes in much greater d
 etail\, especially when precise measurements are required. Landsat photos 
 have the potential to be precisely positioned for comparison with past pho
 tos. This makes the measurement of both the nature of change and their rat
 es to be precisely measured and applied in models of environmental change.
  We are combining historic photos from both southern Italy and the America
 n West with Landsat photos to study changes in the two areas during the la
 st 140 years. In particular\, we are focusing upon changes in both vegetat
 ion cover due to climate change and to the activities of people. We are al
 so investigating relationship between vegetation cover destruction and ero
 sion. We will be use our findings and relating it to specific changes in c
 limate to see what conditions have been the most destructive with regards 
 to both annual rainfall amount and in changes in rainfall seasonality.
