URBAN LANDSCAPE CHANGE IN THE BRAZILIAN COASTAL ECOTONE
The Brazilian coastal regions have been highly modified by intense, diversified and extensive use along its history. These changes were caused, more recently, by increasing urbanization and tourism. This study builds scenarios following landscape ecology concepts to interpret the changes and the impacts in the coastal ecotone of Sao Sebastiao Island (Sao Paulo,Brazil). In such a way, literature surveys of the coastal environment uses and occupation of the island throughout five centuries of occupation have been conducted. Changes in the last fourteen years were analyzed by interpreting and overlapping satellite images (GIS Idrisi Kilimanjaro). The methodology was adapted from Fujihara et al. (2005). The results showed that the largest percentages of human alterations in the island landscape were agriculture until the middle of 20th century,followed by urbanization under the 200m elevation. The forest has regenerated above the 200m level due to legal restrictions. These changes have occurred primarily in the last 70 years.
