Cartografia da dinâmica urbana de uso e ocupação do solo no município de Breu Branco-PA

Abstract

Breu Branco is a municipality in the state of Pará located in the Tucuruí microregion. The municipality became independent in 1991. However, its spatial organization occurred much earlier to meet the demand for housing of the compulsorily displaced due to the increase in the Tocantins river floodplain. The municipality experienced rapid population growth. The initial spatial configuration of the city occurred in the southern portion, between the PA-263 highway and the Tocantins river. Subsequently, with urban saturation, the growth of the county seat reached the other side of the PA-263 highway which is currently the northern side of the county. This expansion process has generated urban occupations that are currently neighborhoods such as Santa Catarina, Conquista and Liberdade. Recently, new urban centers have been emerging. Breu Branco's urban growth is horizontal and spreads along two axes of expansion. The municipal master plan is the document that should contain strategies of environmental zoning and zones of social interest that subsidize the public power in regulating urban growth and environmental protection. The population factor, associated with land price, urban topography and the lack of environmental policies are factors that accelerated the growth of the city. In this work, we use cartographic and remote sensing techniques for the construction of maps between (1996-2006) and (2006-2016), seeking to understand the urban transformations of Breu Branco.
