Resumo:
Cities in the world are undergoing changes in their landscape due to population growth. According to the United Nations (UNITED NATIONS, 2022), it is estimated that by 2030 the global population will grow to about 8.5 and approach around 9.7 billion inhabitants by 2050. In addition, a peak of 10.4 billion inhabitants is projected in 2080, remaining in this range until 2100. Urban swelling often takes direction to areas of native vegetation that, protected or not by law, undergo irreversible changes in their local fauna and flora. For Vasconcelos and Gomes (2012), the process of expansion of cities is linked to how population growth occurs. In addition, both claim that the growth rate of the world s population is increasing at a rate never seen before: the figures represent that this population has doubled since the 1970s. One of the causes of the growth in the case of the Brazilian population in the last 50 years, for example, according to Lebrão (2007), refers to changes in demographic conditions. Previously with high levels of mortality and fecundity, there are currently low mortality and fertility rates that, consequently, corroborates the aging of the population. Population growth and the expansion of cities are associated. In general, the organization of urban space depends on the relations of the population and the offers of living conditions that the urban environment offers. Often the state designs the city according to its interests. The areas that present imminent dangers, end up being occupied by the portion of the population with less income because of the high cost of housing in the regions that provide better security conditions. According to Tucci (2005, p. 13), growth in areas considered at risk is linked to the process of spontaneous urbanization and due to urban planning designed for the noblest areas of the city with a middle and high income population.
