Análise ambiental da área urbana do município de Casca – RS

Abstract

This monograph paper consists of an environmental analysis of the urban area of the city of Casca – RS in order to diagnose the main problems of the environment through the intensity of occurrence of environmental indicators. Thus, it is considered to establish a diagnosis, define the degree of environmental deterioration, and elaborate a cartogram presenting these degrees in sectors. In order to achieve what has been intended, thirty- four indicators were observed in terms of its presence or absence in thirteen sectors. Adding these data, a found value, a minimum value and a maximum value were defined for each sector; afterwards, the calculations adjusting an equation for the deterioration straight line were made. As a result, an index that represents the critical unit of environmental deterioration in each sector was reached. The degrees were defined and since they were grouped as the equation of Sturges, it allowed the elaboration of a cartogram representing the degree of environmental deterioration for the urban space of the city of Casca. Then the following results obtained for the sectors were organized in decreasing degree of environmental deterioration: Consoladora 58,83 %, Center - North 47,06 %, Panisson and Industrial District 41,18 %, São Luís and Jardim Brasil 38,24 %, Bela Vista, Bela Vista II, projected division of lands and Area of Expansion 29,42 %, Center - South and Morada do Sol II 26,47 % and Morada do Sol 23,53 %. Therefore, the study proves that there are differences concerning the amount of deterioration from one sector to another. Such differences deserve more attention from the public service and from the residents, thus, improving their quality of live.
