All the same or different? Scales, appropriations and externalities in housing production at COHAB/RN
This dissertation contributes to the expansion of the debate on the different contexts that are inserted in the actions of the housing policy, with emphasis on the housing developments of the Banco Nacional de Habitação (BNH). The research aims to analyze the production of COHAB in different spatial scales (municipalities and enterprises) and the relationships of appropriations and externalities. Are used as case studies enterprises located in the municipalities of Caicó, Currais Novos, Mossoró and Natal, analyzing the contexts of urban insertions and changes in land use, considering the intra and extra-set differences. The research starts from a literature review with an emphasis on the historical rescue of the BNH's performance as a housing producer agent, this review also involved understanding about the concepts of scale, - key analytical category of the present research - appropriations and externalities. In order to understand the objects, a documentary survey of the urban aspects of the analyzed sets was carried out, which were provided by Companhia de Processamento do Rio Grande do Norte – DATANORTE, by Companhia Estadual de Habitação e Desenvolvimento Urbano (CEHAB), collection of the research group Estúdio Conceito – UFRN and data from Instituto Brasileiro de Geografia e Estatística (IBGE) for the construction of charts and thematic maps. This information was systematized with a spatial reading of this production through tools of Geographic Information Systems - GIS. Therefore, the first findings of the research reveal that housing estates of the same scale, inserted in municipalities of different sizes, have different representativeness (quantitative), appropriations and externalities, making it not possible to build a single prism to address the analysis of public housing production.
