A geologia como base na aplicação Framework Geodesign para o planejamento urbano – estudo de caso: Blumenau-SC

Abstract

The occupation of the natural landscape by man usually occurs in a disorderly and unplanned manner, which is often a synonym for future problems. Therefore, planning a landscape is an extremely important action to optimize natural resources, make better use of the soil and avoid accidents. In this sense, Geology is, par excellence, the science without which such planning is not possible, since it is the one who establishes the parameters of the relief and composition of the rocky substrate, in addition to other data of a technical nature. Then, from the link between science and technique, Geodesign emerges as a method of decision support for landscape planning. In the present work, the first iteration of the procedure was applied in an area belonging to the municipality of Blumenau, Santa Catarina. The central aim was to find socially desirable, economically viable and environmentally sustainable solutions to landscape problems, an objective that can be defined as an "alternative future". To this end, a case study of the area of interest was carried out, and from that, it obtained cartographic data, which were processed on the ArcGis geoprocessing platform, using Geographic Information System (GIS) tools, generating the maps representation of the area. Then, the analysis of these data was carried out, to later produce the evaluation models, these used in the Geodesign Workshop, with a geological bias, as the planning base of the target area. The product generated from the workshop was the decision model, that is, the alternative territorial planning for the study area based on the joint decision of the activity participants, and allied to that, future suggestions for the second and third iteration of the activity. method. It was observed that the participants developed opinions in relation to the area throughout the Workshop, and then sought to develop a plan for alternative futures in the area according to a geological bias. In the midst of this journey, there was a conflict of ideas and few were resolved in the midst of dialogues. Thus, of the twenty-one proposals, only five were accepted, twelve classified as “to be re-analyzed in future iterations” and three rejected. In short, the acceptance of the method by the users was verified, and the final product generated for the first iteration of the method was confirmed to be acceptable.
