Análise do índice de áreas verdes da zona urbana do município de Alto do Rodrigues/RN como subsídio para formulação de manual de arborização urbana

Abstract

Urban expansion in a disorderly manner, especially when there is a lack of relevant legislation, has intensified environmental management caused by the suppression of natural vegetation, with the aim of building the necessary infrastructure for urban development. Once this vegetation with no conservation perspective is suppressed, its ecosystem services are no longer provided, resulting in greater environmental problems. In this context, it was necessary to research the existence and creation of municipal normative instruments that enable the implementation of green areas as a requirement for sustainable urban development. This proposal analyzes the index of green areas in the urban area of Alto do Rodrigues/RN, its compatibility with legal recommendations, its distribution in space and its qualification with regard to use. The methodology used was quantitative-qualitative, following the following steps: (a) bibliographical survey and relevant legislation through research into doctrines, laws, standards and scientific documents; (b) quantitative diagnosis, with mapping of green areas in Geographic Information Systems (GIS); (c) verification of the green area index (IAV) in neighborhoods in the urban area of the municipality; (d) Classification of ecosystem services offered by green area found. The results of this research indicate an index of green areas of 0.02 to 4.85 square meters per inhabitant. The dissertation resulting from the data collected to highlight essential issues in the preparation of an urban afforestation manual, proposing its formulation with normative force. Given the low rates of green areas, the need for investments in infrastructure, creation of specific legislation and integration between bodies to promote more sustainable urban environments stands out.
