In this direction, the city must be understood by the dynamics of the territory, for as if of its organization space, what it means a perception more dynamic, marked for the interaction of nets of communication and materialization of urban flows. It stops beyond describing given, urges to understand them. Ribeiro (2004: 22) affirm on the social segmentation its consequences when studying ' ' the population of eight regions metropolitans jumps in last the ten years of 37 million for 42 million inhabitants, and its peripheries know a tax of 30% growth, while the areas more central offices of the metropolises do not grow more than 5%. We have a period more each polarized time. After 1996, the per capita income in the Brazilian average cities increased in 3% and in the peripheries of the great cities it diminished in 3%. It has ten years the violence in the peripheries was another one.
They were committed about 30 homicides for 100 a thousand inhabitants. The Brazilian metropolises concentrate today, therefore, the national social matter and express the deepening of the divorce between the society, the economy and the Estado' '. The questions brought for Ribeiro is very bigger of what simply describing the data. One is about an analysis of the urban social problems and the paper of the State. A good content of geography demands, to if studying the city, the comment of the commercial areas, the historical center, the residential areas, the irregular occupation, the geographic exclusion and its correlation, allowing to the pupil the understanding of the value of the city and its space conflicts and contradictions. From the study thus lead the pupil she understands the meaning of the experience place, of the belonging, she reflects on standards of segregation in the management of the urban problems – they are of that nature will be -, associate ambient phenomena to the management of natural resources (water, sewer, sanitation, emission of pollutants, etc.), of preference comparing what she happens in diverse realities of other cities, states or countries with its personal experience.
