Estratégias de avaliação da disponibilidade de arborização urbana em logradouros públicos

Abstract

This research examines the municipal management of green areas and tree planting in Belo Horizonte, presenting strategies to assess the availability of these resources. The analysis begins with a literature review that addresses the legislation and management tools used by the Public Authority to deal with green areas and the management of tree planting in the city. For this purpose, data from the municipal tree inventory, geographical information from the Belo Horizonte City Hall, and data collected in field surveys were used. The obtained data were organized into tables, graphs, and maps. This research contains analyses based on consolidated indices and indicators such as: Green Area Index - IAV; Protected Green Areas Rate - IAP; Vegetation Cover Index - ICV; and Normalized Difference Vegetation Index - NDVI. In addition to these consolidated indices, two new indices are proposed for assessing the availability of tree vegetation: the Tree Cover Index - ICA and the Visible Vegetation Index - IVV. This dissertation seeks to bridge the gap between municipal urban planning and the human scale, which is better suited to local planning. For this reason, analyses were conducted on the characterization of urban tree planting in the neighborhoods of Santa Tereza, Vila Dias, and São Vicente – in the eastern region of Belo Horizonte. With the application of parametric 3D modeling, a model of the study area was generated showing the distribution of trees in public spaces, the volumetry of buildings, the road network, among other elements. Finally, the research results are discussed, including the pointing out of possible future applications. The possibilities of using the research at the Municipal Environment Secretariat of Belo Horizonte are highlighted, as well as potential developments in further studies.
