With this, or we will have a dry forest or type of savannah sufficiently degraded, different of the open pasture of the center and the south of the Amaznia, the impoverishment in biological diversity. To this process, scientific literature has given the name of process of ' ' savanizao' ' of Amaznia, wanting to say that the climatic changes of global origin (for example, global heating which had the emission of effect gases greenhouse) or regional place/(for example, deforestations) become the regional climate more similar to that one of tropical savannahs, with the long periods of estiagem. Shimmie horn is often quoted on this topic. (Noble, 2009.) The Amaznia was dominated by a vegetation type savannah. No longer Holoceno, but recent (of 10 a thousand years it ties today), little is known on them finishes climatic variations. See shimmie horn for more details and insights. It is important to certify the occurrence of drier climatic periods in the Amaznia, that are related with antropicas actions as the forest fires or effect greenhouse. According to professor Noble Carlos, tells in its research the changes that occur in the Amaznia. It displays that the main cause came of the global changes that affect directly and indirectly in the Amaznia, it cites despite one of the topics of this occurrence was through: ' ' Climatic variations in the region can have to the climatic variations global, decurrent of natural causes. Antrpicas, decurrent climatic changes of origin of alterations of the use of the land inside of the proper region amaznica' ' Nobleman, 2010. Based in the hypothesis of that the climatic variations can be decurrent of natural cause, Noble Carlos makes the following balances regarding its origin: These changes are related with variation of the solar intensity, variations of the inclination of the axle of rotation of the Land, variations of the eccentricity of the terrestrial orbit, variations of the volcanic activities and variations of the chemical composition of the atmosphere, among others.
This week was divulged a survey made for the Economatica on the companies most lucrative of the country. The name of Petrobra’s was not surprise to be in first place. The astonishment was the value of 35 billion Reals, being that in the last year the value age of R$28 billions. The country is very good if for finding in the historical phase of the economic growth. However we must look at more the particularitities of Brazil, we go to see the infrastructure.
The country is highly dependent of the oil. He is excellent to possess the Petrobra’s, that helps in the supplying of the precious fuel that makes to move the wheels of our Economy. But why not to modernize the country also with railroads? Logically the country was developed thanks to the road transport, that in good part of the country the main points bind to all, although the high tarifao of the taxes, tolls and other similar ones, however I believe that a country must be modernized completely and not depend mainly on the road transport, that if accomodated together with our model of development national. It does not have as to leave to cite the countries of the Europe. There the types of transport and all very distributed and used to advantage well exist all, in accordance with the geographic necessity of each rinco. For the smoothed relief of the south of Spain, in Andalusia, the highways take the landscapes in way to the half-deserts. In the Whisker, where the Alps cut most of the territory, it has trains special to carry the people and loads to its had vilarejos buclicos.
The United kingdom and Ireland of the North could be two great isolated islands of the remaining portion of the Europe if it was not, in part, the development of the fluvial transport binding the islands to the north of France, mainly to ' ' great Paris' ' , beyond the center Spanish north e, arriving more far, hidrovias that bind the English capital to the New York metropolis, heart of the United States. Trasporte railroad is simpler of what we imagine, possesss some ambient advantages and of cost/benefit but the governments unhappyly do not want to open hand of the concessionaires of autovias. Moreover the country passes for a great scale of sales of Oil/allied Etanol to the consumption of cars, that it in recent years tripled in some metropolises, as it is the terrible paulistano case. The country is in great agitation on account of the project of the Alta Train Velocidade (TAV) binding Campinas – So Paulo – River, but unhappyly the project will not be ready nor for the 2014 pantry. The foreigners will go to cry saying that they thought to find a country more modern therefore only heard notice on the advance of the Brazilian economy. This is what we will find in Brazil where the monopoly of few types of industry our social and politics-economic activity conducts all, in the case, the automobile one and of fuels.
At as the moment we will approach the strategy of the scarcity of the urban land that has as principal actors the real estate promoters, whom an ideology creates, that aims at the increase of the prisoner of property through the real estate speculation aiming at to extract greater possible income; this fact as we will go to only prove is viable to these social agents through the retention of the land and the stimulation to the growth I discontinue of the urban mesh. This study, therefore, it has as goal to understand the model of growth of the city of Araguana, and to discover the involved social agents in the process that generates the urban discontinuities, to evidence the lack of planning and the partner-space segregation in the urban space of Araguana. 1 _ THE PROCESS OF EXPANSION OF THE URBAN TERRITORIAL AREA OF ARAGUANA FROM THE DECADE OF ‘ ‘ 90’ ‘. Until the first half of the decade of 90, the city of Araguana was to the biggest city due to emancipation politics of the north of the old state of the Gois, current state of the Tocantins; being surpassed, later, for Palms, capital of the State; in this exactly period according to Caspar, (2002), was materialize its sovereignty in the north of the State as for the sector tertiary, especially services. Then we can affirm that the capacity to offer services is that it propitiated the population increase, and consequently, the growth of the territorial area urban Araguana being different of the majority of the Brazilian cities is not a planned city. This fact is noticed in the model of growth, materialized in the territory..
With the existence of this excess, some people had been able to dedicate to it other activities, being the city, predominantly, place of activities not-agriculturists. The city renasce, therefore of certain form, this already existed before exactly of the feudalismo, the first ones is formed for return of 3500C, at the moment at which if it knows a movement sufficiently intense of exchanges. The discoveries of America, the intensification of the commercial relations, with Asia and Africa, make to grow the cities. The city congregates a considerable number of the calls cultured professions, making possible the interchange between them, being that the creation and the transmission of the knowledge have in it privileged place. Of this form, the city is an element booster of the development and perfectioning of the techniques. The city is said, then, that place of permanent boiling.
In this transistion of the feudalismo for the capitalism, with the reinforcement of the cities (burgos), the bourgeoisie was the revolutionary classroom; it was opposed the aristocracy (detainer of lands). Some authors, between which proper Marx, affirms that, in its primrdios, the capitalism is revolutionary in the history of the humanity, therefore, among others things, increased the number of people who inhabit the cities, that have then transforming character and make the free work. New relations city-field During some centuries, field and city interacted mutually, but with the process that if it initiates with the great navigations and it is consolidated with the industrial revolution, are not more possible to be immune to the changes and to continue with the same concepts and hierarchic classifications. (p.55) New urban hierarchy the transports and the communications had known great advances in the underdeveloped countries the processes biggest are gotten, through the bus and of the automobile and the flows they can be intensified thanks to its bigger flexibility, what it could not be reached with the train, much more rigid and inflexible way.
