Áreas verdes de Fortaleza: uma análise quantitativa dos territórios sob proteção ambiental na cidade

Abstract

The changes in the urban space suffered by the Brazilian municipalities with the disordered processes of city expansion are a problem for the administrated organs and for the inhabitants of these urban centers, such as a city of Fortaleza. The environmental impacts generated by this urban growth, without adequate planning to meet the demands of the population, motivated the diagnosis and prospecting of mitigating measures for biodiversity conservation, ecological balance and quality of life of the inhabitants of Fortaleza. Aiming to analyze the current situation of the city of Fortaleza in relation to its green areas, such as Conservation Units, as Permanent Preservation Areas and Municipal Urban Parks, this research makes a quantitative analysis of the current extension of current green areas from the analysis of surveillance and geotechnologies, with data provided by the Fortaleza City Hall and the State Register of Conservation Units (CEUC), and proposes a calculation methodology for the Green Areas Index (IAV), an index that calculates a green area extension of one region per inhabitant. In the analysis, it was noticeable that many of the green areas of Fortaleza are betting on each other, showing territorial extension numbers that do not express the reality. In addition, the green area polygons demarcated by the Fortaleza City Hall include water mirrors and areas occupied by civil construction, and may also exhibit unrealistic vegetation cover values. Nevertheless, the result is the latest in recent years to create extensive Conservation Units and numerous Urban Parks that are essential for increasing the municipality's IAV and the development of environmental protection policy.
