Ocupações irregulares e sua dinâmica em áreas verdes urbanas: um estudo de caso no Parque Linear Urbano Machado, Palmas-TO

Abstract

The master’s thesis titled “Irregular Occupations and Their Dynamics in Urban Green Areas: A Case Study in the Machado Urban Linear Park, Palmas-TO” investigates the complex relationships between urbanization and environmental preservation in a Permanent Preservation Area (APP) in Palmas, Tocantins, Brazil. The study was motivated by the rapid urban expansion that has negatively impacted these areas, compromising environmental sustainability and the quality of life of the residents. The primary objective of the research was to understand the dynamics of land use and occupation around the Machado Stream, identifying the responsible socio-environmental agents, mapping the irregularly occupied areas, and analyzing the land use conflicts resulting from these occupations. The methodology adopted was a case study with a quali-quantitative approach, utilizing bibliographic research, documentary analysis, field research, and geoprocessing techniques for mapping and multitemporal analysis of occupations. The results revealed that urban expansion is largely influenced by real estate speculation, lack of enforcement, and the absence of effective public policies for planning and land regularization. The mapping of the occupied areas over time showed a significant reduction in vegetation cover, highlighting the anthropogenic pressure on preservation areas. The identified land use conflicts demonstrate a growing tension between economic interests and the need for environmental conservation, with irregular occupation promoting the degradation of natural resources and increasing the population’s vulnerability to environmental disasters. The research concludes that urban management in Palmas faces significant challenges, requiring an integrated approach that combines public policies, community participation, and sustainable urbanization practices to mitigate negative impacts and promote balanced and environmentally responsible urban development. The final considerations highlight the need for public policies that can effectively regulate land use, prevent irregular occupation, and promote the recovery of degraded areas. They also suggest directions for future research focused on the relationship between urbanization and environmental preservation in other critical areas of Brazil. This thesis contributes to advancing knowledge in the field of Environmental Sciences, offering relevant insights for both the theory and practice of urban environmental management.
