Avanços e desafios na aplicação da modelagem para o mapeamento da dinâmica de mudança de uso do solo em áreas urbanas

Abstract

The modeling of land use change for urban contexts has been increasingly addressed by an interdisciplinary and sophisticated approach which uses spatially explicit data both from past and present times that allow the simulation of future scenarios of land and occupation. The simulation of future urban space allows the prediction of problems concerning the advance of the urban occupation upon areas of relevant environmental preservation, or the ones with poor infrastructure. This paper aims to present a critical analysis about urban modeling based on a brief bibliographic review, and aiming to help to understand the benefits of the urban modeling as much as the challanges which are still faced in the use of this tool. Therefore, four papers were selected as case studies. Two of them were in the Metropolitan area of Belo Horizonte, the third one was in Distrito Federal, and the last was in Sete Lagoas. For each one of the case studies, the methodology was analysed in a way to critically review and compare them, considering their technology innovation, and the advantages of their use in the public politics.
