The Municipal Biological Reserve of Serra do Japi shelters an important forest remnant of Atlantic Rainforest in the state of São Paulo. For its ecological importance, were created instruments for environmental and territorial management of the Conservation Unit, with the regulation of the use and occupation of the land in its Buffer Zone (BZ) in 2004. The objective of this study was to analyze the evolution of the land cover in the BZ region of the Municipal Biological Reserve of Serra do Japi in Jundiaí-SP, between 1989 and 2010. It was used in this study the image analysis of the satellite LANDSAT-TM5, with the help of software ILWIS and IDRISI. The results showed that urban occupation has increased 37.47% and the agro pastoral and reforestation areas have decreased 36.62% and 72.22% respectively, while forest areas have increased 49.57%. However, the relative importance of the forest area in BZ ranged from 46.60% in 1989 to 69.71% in 2010, leading to the conclusion that this region was favored by changes in land cover in the period evaluated, despite strong pressure for urban expansion in its surroundings.

Water erosion is one of the main processes responsible for soil degradation, resulting in loss of parcels of land suitable for agriculture, to the loss of agricultural inputs and the resulting drift of pesticides and excess sediment to rivers, causing phenomena such as the siltation and eutrophication of water bodies. Such a scenario makes it necessary to perform work of a technical and scientific to provide subsidies to land-use planning, in order to protect natural resources biotic and abiotic. To develop this work is necessary to find a unit of analysis capable of integrating the different elements of the landscape, hydrosphere, atmosphere, biosphere and lithosphere. Therefore we adopt for this work the watershed as main unit studies. From this question, this project will focus on the assessment of surface water erosion through MEUPS (Equation Modified Universal Soil Loss) predictive model. With the aid of maps, remote sensing products, and the use of geotechnology, this study aims to evaluate for the for Natural Erosion Potential the basin of the Jacutinga river, located in Rio Claro - SP

Landscape is the result of interaction between tectonic, weathering and pedogenetic processes, so it is necessary to understand the morphogenesis and relate it to the landforms and landscape. Therefore, this project comprises a geomorphological characterization of some areas associated with the fault zones of Taubaté Basin, at the surroundings of the cities from São José dos Campos to Taubaté SP, emphasizing the Quaternary landscape evolution, where the normal faults played an important role in controling and they were originated, mostly, from the reactivation of Precambrian fault zones by tectonic action. The rift valley scenario is highlighted in the region, identifying the sharp relief from the basin boundary, featuring both Serra do Mar and Serra da Mantiqueira, and a central depressed area where the Taubaté Basin is located. Deforming or modifying basin features are identified, promoting the rearrangement and conditioning of the drainage network and relief, which indicates the presence of morphostructures, conducting to the deduction of a late tectonic process
