Landscape Ecology: Landscape Transformations in the District of Icapara in Iguape (SP) Andre Freitas, Fabio Giordano, Mara Angelina Galvão Magenta

Abstract

Since the launch of the first satellite in 1972 , the Landsat program brought together images of the terrestrial surface, creating the most complete record ever assembled. These data , provided by Google Earth platform , reveal the dynamics of landscape changes over time due to human activity and natural processes. The lagoonal system Iguape-Cananéia, as well as other estuarine systems, has a natural dynamic transformation of its landscape. The time scale of these changes can be millenniums or years, as in the mouth of the Ribeira river, where the NE portion of the municipality of Ilha Comprida has been experiencing an increase in their territory by the movement and deposition of sediment, typical of barrier islands . As a result of this sediments movement dynamic, the neighborhood of Icapara in the municipality of Iguape is losing territory to the sea, causing material losses to the population of this region. With the use of AutoCAD software and two satellite images (2001 and 2010), was performed a mapping of these changes in the landscape to quantify the loss of territory in the district of Icapara, on a time scale of nine years. The study pointed loss of 74.25 ha of land in the border area and can be a register for further studies
