A growing urban population fears the need for city expansion, causing non-environmental transformations, capable of creating its own microclimate, which can form heat pipes. The purpose of this work is to analyze the urban expansion process in the Macapá Headquarters District, Capital of the State of Amapá, located in the Brazilian Amazon and the non quantitative impact of vegetation cover. The applied methodology is derived from the analysis of two popular data from 1960 to 2010, made available by the Brazilian Institute of Geography and Statistics and analysis of the growth of urban area and its non-quantitative impact of vegetation cover in the period from 1985 to 2015, using the classification Supervised by Maximum Likelihood in satellite images. The results obtained are based on the fact that from 1960 to 2010 or population increase in the State of Amapá, in order to concentrate a greater part of the population in urban areas, mainly in the Capital, it has 59.47% of the state population, being that 93% of the population of Macapá resides not district headquarters. An analysis of the images from 1985 to 2015 shows that an urban area tripled in this period, causing a decrease of 48.91% of closed and 17.13% of vegetation. The period of greatest loss occurred between the years 1985 and 1993, confirming that the vegetation cover of the Macapá headquarters district had been directly impacted by the growth of the city. Reflection on the reduction of green areas and loss of environmental quality related to the microclimatic factors performed by urban vegetation.

Projeto de macrodrenagem da Bacia do Una e índice de qualidade de vida de seus moradores
(Universidade Federal do Pará, 2004) BRASIL, Syane Cristina; TOBIAS, Maisa Sales Gama; http://lattes.cnpq.br/9635266655242384; CARDOSO, Ana Cláudia Duarte; http://lattes.cnpq.br/3138101153535395
This thesis addresses the investigation about quality of life conditions of population resident in the area affected by Una Basin´s Macrodrainage Project (PMU). This project embraces nine neighborhoods of Belém -PA. It was developed to clean up and to recover flooded areas in the city, generating better life conditions for its inhabitants. This research aims to evaluate the effects of the cited project on inhabitant's life conditions. The methodology adopted incorporates the inhabitant’s vision about the intervention and, also, promotes a comparative analysis among the several areas reached by the project. The research identifies aspects of inhabitants‘ lives such as habitation, infrastructure, public services and accessibility conditions. The project is not completely consolidated yet; however, we already shimmered positive and negative points of the intervention. PMU didn't get to satisfy the expectations of the involved population over its execution, in spite of the abundance of financial resources, professionals' support, management and planning actions from several government spheres, besides the support of the involved entities. Several reasons handicapped the project’s aims of improving the quality of urban life of 60% of Belém`s population. Quality of life assessment was the approach adopted, through the construction of an index capable to identify and mensure the levels of lack or satisfaction of case study areas’ social needs, though the questioning on satisfaction of inhabitant’s expectations. This index was obtained trough indicators collected through semi-structured interviews in three sub areas of the project originated as informal settlements and in the Paraíso dos Pássaros, area built to shelter the inhabitants realocated for the macrodrenagem project, which received 2000 families. This investigation is important to know the real effects of official actions and public interventions, as it is the case of PMU, on inhabitants‘ living conditions of affected areas. It is expected that the proposed index will subsidize technical and political decisions about planning and urban administration for the study area and to define spacial and sectorial priorities for urban intervention, facilitating a more efficient and just public resources distribution, and favoring the sustainable improvement of quality of urban life. This work hopes to help in setting standards for decision-making, regarding to action priorities and urban investments and, specially, to the formulation of public policies to combat social exclusion.
