The region of the biome Cerrado is under threat due to the replacement of their native areas for expansion of agriculture and livestock. This occupation is responsible for the loss of about 50% of two million square kilometers of original native savannah. The land use, without control or zoning, has caused serious damage to natural resources of this biome, considered as an international hotspot area. As a result, some problems caused by ecological imbalances already topping the urban and rural environments, such as species extinction, water scarcity and desertification. Any occupation in this biome should be evaluated with caution, because this region, besides being considered one of the most productive of Brazil, is also rich in biodiversity and water resources. The understanding of the importance of the Cerrado biome and its remaining areas, allows the preparation of detailed studies of environmental valuation, which is essential for the development of conservation policies, avoiding even greater environmental impacts. To meet the growing demand for food, you can increase productivity through agroforestry, for example, and to preserve the remaining areas, you can create new protected areas and tailor existing units

Planning is an essential instrument for the agricultural occupation of the lands, because it supports the activities of food production and raw materials. It must be driven by techniques that provide the sustainability of these activities, so that also ensures the environmental balance of agroecosystems. Lands misuse can be considered as one of the causes of frustration of agricultural activities. Thus, the occurrence of discrepancies between the effective use (real use) of the land and its agricultural aptitude can compete, in many cases, to the decrease of productivity, as well as for soil degradation. In this way, this research intends to study the relationship between the temporary cultivations, halfperennial cultures, perennial and its developmental environment, determining the edaphoclimatic characteristics of landscapes. From then on, a letter shall be subject to the use and occupation of the soil for agriculture in the municipality of Cristais Paulista-SP, aiming to describe the spatial organization of land use and vegetation cover, and emphasizing management and conservative practices. For that, climatic factors were characterized, fundamentally humidity, temperature and luminosity; edaphics, including parental material, chemical and physical properties, fertility, soil temperature and climatic zoning; biotic, referring to the suitability of different cultures or to be implanted; physical, such as geomorphology, slope, geology, hypsometry and hydrology; socioeconomic, in particular production and marketing seasons; and the way they all, together, affect the adaptation, distribution and production of crops. Using this information, the zoning of the area of study was done based on the 21 nominated groups obtained, in addition to recommendations and suggestions for handling each type of cultivation...

The spatial chaotic urban growth is an increasing and common problem in Brazilian cities, especially in the State of São Paulo. In order to assist the territorial expansion planning, the present study aimed to conduct the environmental diagnosis of urban expansion areas in the City of Jaguariúna – SP, bounded by the Municipal Plan. From the preparation and analysis of thematic maps, literature review and field analysis, data were collected for use and occupation, geology, geomorphology, pedology, vegetation, water resources and features surrounding the five urban sprawl existing areas. It was noted, in general, that these areas are suitable for urban occupation, since they show flat geomorphology characteristics, with flattened, medium to large hills, slightly undulated, with low slope, and soils that do not present risks to the deployment of buildings, once properly managed. It was also observed a few water bodies crossing these areas and a few areas with native vegetation beyond permanent protection areas along the rivers. By the analysis of these areas and their surroundings, it was possible to determine on which area the urbanization process can occur more quickly. Thus, the study allows the City of Jaguariúna to perform a more effective occupation planning in these areas, always aiming the sustainable development and, consequently, the improvement in population’s quality of life, as well as the maintenance of environmental quality.

Construction of linear engineering as, roads, ducts and multiducts as roads, has a strong feature of the diversity of land on which they are deployed. This diversity involves properties geological, geomorphological and structural variety. The purpose of this work is to characterize the physical environment in relation to their ability to support the implementation of civil works linear. To achieve this, the use of orbital remote sensing, in this case, Landsat - TM. Interpretative techniques are applied to images in order to assess the forms of relief and drainage found that they can set properties and have built a favorable meaning or not to implement these works. The results and thematic maps presented in this study allow us to promote the geoenvironmental analysis for the planning phase sustainable linear civil constructions (roads and multiducts)

This research presents the result of the engineering geological mapping in a 1:50.000 scale, in Bairro do Peão region, in Piracaia (SP), represented by means of homogeneous units which are susceptible to superficial dynamic processes. To serve as basis for the elaboration of a Chart of Susceptibility to Processes of Superficial Dynamic, a series of physical samples was collected, considering erosive processes and registers of information of usage and soil occupation. The procedure used for elaborating the geotechnical chart is based on Vedovello (2000), which suggests the physiographic compartimentation of the area through photointerpretation and further geotechnical characterization of the selected samples. The geotechnical characterization of the samples was made by identifying the features and properties of the material and forms of the physical environment determining the geotechnical conditions through geological-geotechnical profile descriptions typical of/ peculiar to each unit defined in the area. Thus, for each unit selected, the susceptibility level was established in very high, high, average and low, as well as the prevalent erosive processes.

We aim to contribute to studies on the restructuring of the city with a focus on consumption. In the context where cities become the main place of action of man, a deep set of transformations has occurred. We are interested in understanding the redefinition of the logical production and appropriation of urban spaces for consumption of materials and services. For the analysis of delimitation of those commercial and service areas was made to compare the reality observed on the ground and indirectly through data acquisition and mapping obtained from the National Address List for Statistical Purposes, with the boundaries established by zoning and / or by municipal director plans of the cities studied, together with the classification of commercial establishments and in accordance with the standards of the National Classification of Economic Activities Services. We believe the importance of analyzing the process of concentration and dispersion of stores and / or services of Londrina (PR), Presidente Prudente (SP) and Ribeirão Preto (SP)...

A contaminant plume due to leachate infiltration was found in the solid waste landfill from Bauru, SP. The soil hydraulic conductivity (K) is an important parameter to understand the moving of this plume. This paper intends to show representative K values for the soils that occur in the vicinity of this landfill determined by field and laboratory tests. There are four soil types in the area: colluvium, alluvium, sandstone residual soil and the sandstone. Laboratory tests were performed using constant and variable head in rigid and flexible wall permeameters. Slug tests and hydraulic conductivity tests with the Guelph permeameter were also carried out in situ in the area. Representative K values of 3.7x10-7 m/s for the saturated zone and 2.4x10-8 m/s for the unsaturated zone were determined for the residual soil. A K value of 5.3x10-5 m/s was obtained for the colluvium soil. A great variation of K with depth was observed for the alluvium and the assumed average values for the saturated zone were 7.9x10-7 m/s and 1.1x10-4 m/s for the unsaturated surficial layer. An average K value of 3.3x10-8 m/s was determined in laboratory for the sandstone and it was assumed representative for this material.
