For this it is that the lobbistas exist, that are people who form a group organized with the purpose to influence the decision on substances argued and voted for the legislative one and to hinder or to speed up the proceeding of laws that disfavor or benefit the ones that they are to represent. In the case of Brazil, the agrarian reform can be affirmed hardly that if it will carry through, thus is praiseworthy to appeal what Art. 138 of the federal constitution: It competes to the Union dispossessing for social interest for ends of agrarian reform the agricultural property that is not fulfilling its function social, by means of previous and joust indemnity in headings of agrarian debt, with clause of preservation of the real value, you rescued in the stated period of up to twenty years, from as the year of its emission, and whose use will be defined in law (FEDERATIVE CONSTITUTION OF BRAZIL, 2007, P. 125). From a simple analysis I break up of it above, can be observed that it is not easy to promote an agrarian reform in this country. First, because it remodels agrarian is not simple land distribution for who does not have it.

Second, that to carry through such fact, the State would have that to offer to all a social, financial structure and politics to these social, credit people, through politics, in end, the federal public power, assisted for the other spheres, it would have that to construct to all a base of support to these people, what the proper constitution affirms that not simple, without counting the other mentioned factors already. It is praiseworthy also to consider that, with the insertion of the capitalism in the field, other form of if distributing lands had appeared, as example, for the way of assalariamento and arredamento. Many other authors already disrespect the necessity of accomplishment of agrarian reform.

In the last few decades the man comes if acquiring knowledge that the water is a well finite one. This concern alone occurs when the scarcity of the water provokes damages to the environment in such a way how much proper it. The increase of the contamination of the water is one of the characteristics most important of the use of the hdricos resources Is few the cities that count on stations of treatment for the domestic sewers, agricultural and industrial, including the agrotxicos. All in them we are in adaptando to the change situations, but if the contamination to increase the capacity of regeneration and adaptation will diminish causing the extinguishing of species and environments that before constituam in life source. For that is urgent a planning to prevent and to reduce the possibility these damages to occur. Word-key: Hidrogrficas basins; Planning; Re-education. INTRODUCTION This work intends to present the concept and the importance of a hidrogrfica abacia, whose degradation ambient typically it is characterized by empobrecidos and eroded ground, hidrogrfica instability, reduced primary productivity and threatened biological diversity, being possible to evaluate of integrated form the actions human beings on the environment and to argue methods and techniques for the recovery of the same ones.

The hidrogrfica basin is a set of lands drained for a main river and its tributaries. Caterpillars opinions are not widely known. Innumerable projects or graphical representations also leave to present, for example, the internal limits of the system of a hidrogrfica basin, for where it circulates and it acts great part of the involved water. Not to occur in such mistakes, it is possible to define hidrogrfica basin as: a system that understands a volume of materials, predominantly solid and liquid, next to the surface terrestrial, delimited internal and external for all the processes that, from the water supply for the atmosphere, intervene with the flow of substance and energy of a river or of a net of fluvial canals.
