Conurbação e dispersão em aglomerações urbanas: desafios ao planejamento
MetadataMostrar registro completo
Brazilian cities have gone through numerous setbacks in the last decades to house the bulk of the population is concentrated in these areas in search of a possible improvement in quality of life and economic opportunities. The unpreparedness of the municipalities to add all of this population is reflected directly in the environmental and social inequalities, the main characteristics of the cities. Those who concentrate the majority of the population - mostly urban agglomerations and metropolitan areas - are often those with the most obvious impacts and inequalities, with inadequate planning and management policies or the weak socioeconomic and environmental development. It is increasingly and evident the constant attempts of urban planners in creating mechanisms to control the use and occupation but, however effective they may be those regions with higher population density and strong traces of agglomeration and conurbation, usually do not develop mechanisms integrated planning of land use. In this sense, this proposal aims, through the use of Geographic Information Systems (GIS) to analyze the temporal process of formation of the urban area of Londrina (Paraná, Brazil) and evaluate, through development of subdivisions, zoning, provision of infrastructure and other relevant data how the inter-municipal relationships occurs and demonstrate that the lack of integration between the municipalities in the constitution of the instruments of control over the use and occupation of land can cause numerous impacts on the metropolitan and urban areas and as a consequence many difficulties for planning city.
