With the growing population in the large urban centres, environmental problems caused by it are increasingly common, with more serious consequences. Manaus CITY is also suffering with the problems presented by the lack of preservation of their gallery forests, which are being amended and modified by anthropic. However, this work has as main objective, to study the environmental impacts occurring in a riparian Forest existing in the urban area of this city, because of the construction of a complex of a private property, and as a result of such valuation economic impacts. The compilation was done in three stages, the first one being the identification of the area through images of location of the area of permanent preservation, surveying and handling of technical reports; the second was the bibliographic survey to sustain the discussions from surveys performed in results acquired, referring to the valuation of environmental compensation executed in the affected area, and the third part was the development and implementation of the project of recovering area degradas to restore the losses identified and promote regeneration of this area. Through the tools employed, could be reached to the conclusion that the anthropic exerted by the enterprise to negatively affect the area addressed, such as improving the rate of sedimentation to the amount, change in the concentration of solids and increase in turbidity and the emergence of voçorocas over much of the bed of igarapé, thus bringing harm to local fauna and flora. With the use of mathematical tools, could be performed to calculate the economic valuation of environmental compensation, which indicates a theoretical value that corresponds to the costs to compensate for what has been degraded in the area. Depending on the situation presented, drafted up the Plan of recovery of degraded area, in order to mitigate the negative effects suffered, where the actions taken were very efficient, according to the results obtained in the medium and long term in the area impacted.

Environmental problems currently constitute one of the biggest concerns of the global scientific ambient. In this sense, this work had as objective the analysis of the environmental impacts arising from mineral extraction and changes in physical and biotic environment. The results through the method of "check-list" showed that although such projects bring radical environmental effects is possible to minimize the negative effects of mining, at all stages of the project, with solutions based on the analysis of monitoring and correction, for satisfactory results and the re-composition of the striking scenery. The main conclusion is that this study can be used as a theoretical framework to support the process of environmental licensing of this type of venture. [ABSTRACT FROM AUTHOR]
