THE URBAN GROWTH AND SPRAWL OF ARARANGUÁ CITY, SANTA CATARINA STATE, FROM 1957 TO 2010 AND THE ENVIRONMENTAL CONSEQUENCES

Abstract

This study aims to map the urban sprawl in the city of Araranguá, Santa Catarina, and to analyze the environmental implications on water springs, wetlands and water bodies. The mapping and elaboration of thematic maps were done through geoprocessing techniques. The perimeter occupied by the urban mesh in 2010 was adopted as the area to be mapped for the multi- temporal analysis of land use and cover changes. Above this perimeter was added a buffer of two kilometers radius for the verification of the spaces proper to the future urban sprawl. The rapid advance of the urban area of Araranguá city above the Permanent Preservation Areas, as well as the environmental degradation verified, alerts us to the urgency in the revision of the Municipal Master Plan, as well as the establishment of territorial management programs based on interdisciplinarity.
