Em busca da cidade sustentável: indicadores de sustentabilidade urbana a partir do bairro Grotão-JP

Abstract

Cities assume an increasing relevance, constituting complex and dynamic systems, where most of the population, economic activities and wealth are concentrated. The fact that urbanization in Brazil occurred quickly and disorderly generated a great challenge for sustainable development. The Brazilian urban population has grown more than 100 million people in 50 years, with this demographic explosion and lack of management, a series of problems arise, including environmental problems. In this perspective, the work studies the reality of the Grotão neighborhood, located in the municipality of João Pessoa, using a methodology created and developed by the Urban Ecology Agency of Barcelona, to define whether the neighborhood is considered sustainable. With this, effective parameters can be defined to assess their situation, providing society with instruments for charging the government for efficient urban management policies. Images available in Google Earth were analyzed and data were obtained from several officialsources. Ten indicators were generated and from them an index was developed that will identify the level of sustainability of the neighborhood, as a sample of the peripheral neighborhoods of the city of João Pessoa. According to the data collected and obtained through satellite images, it is evident the neglect and the need for improvement in the infrastructure of the neighborhood, which presents a degree of sustainability below average, being of paramount importance the presence and action of the public power, together with the population, so that not only the neighborhood itself, but the city can grow and follow a model of sustainable development.
