Soil is a natural resource that allows the maintenance of life on Earth, therefore, it is important to appreciate techniques to assist the conservation of their quality, since the inadequate management of its use causes their degradation. In this sense, the soil pH values of the city of Sorocaba (SP) were analyzed using a pHmeter and a GPS, with 112 points distributed homogeneously in the study area and another 50 random points to verify spatial variability through geostatistical interpolators of ordinary kriging and deterministic of inverse square distance (ISD). The predominant values of pH per soil class were also determined. The pH values predominated between the ranges of 6.0 and 6.5; totaling 74.98% of the study area for the ordinary kriging method and 75.93% for the ISD, observing a low variation among the methods, which result in a root mean square error values of 0.349951 for ordinary kriging and 0.349019 for the ISD. The concordance index for both methods was 0.9944 with mean standard deviation of 0.0374 for ISD and 0.0369 for ordinary kriging. For the different soil classes, pH values ranged from 5.9 to 6.3. Therefore, both the theoretical models applied in the interpolation of the pH data efficiently explain the pH variability of the Sorocaba soil. [ABSTRACT FROM AUTHOR]

Fragmentation of habitats and isolation of populations is one of the most serious biodiversity threats. Such changes may affect the composition and abundance of avifauna species. Therefore, the aim of the present work was to investigate how biodiversity behaves in relation to the landscape matrix for a better understanding of the forest fragmentation processes. Thus, geoprocessing techniques were used to allow the evaluation of forest fragments regarding as to the form and pressure of the anthropic activities carried out in their surroundings. In addition to the observed variables, a survey of the avifauna was carried out in 15 forest units. As a result, 147 bird species were observed, with an abundance of 6,000 individuals. To evaluate the occurrence of correlation between the variables, a multiple linear regression test was performed with the ecological indexes and the values of richness and abundance of birds. Proven relationship between the increase or decrease in the number of species with the abundance of the birds was found. Additionally, no direct relationship between geographic form, NDVI, type of soil used in the fragments or level of anthropic pressure of forested areas with richness and abundance of birds. Considering the complexity of a whole ecosystem, it is essential to deepen the studies of environmental variables in order to find a mathematical model which allows a more efficient estimation of animal diversity according to the characteristics of the environment.

The problems related to water resources has been the scene of debates due to steady deterioration of water quality and increase in demand. This study aimed to analyse the influence of land use and occupation in the water quality of the main rivers of the Environmental Protection Area (EPA) Itupararanga (SP), Brazil. Therefore, analyses were carried out of the main parameters and water quality indices, as well as the mapping of the use and occupation of land. The results revealed that the sanitary sewage conditions of the municipalities of the EPA Itupararanga and agricultural uses classes are negatively affecting the water quality.

The watersheds are fundamental in the management of social policies, allowing for the measurement of physical and socioeconomic characteristics through indicators such as the HDI and SII. This study aims to develop the Socioeconomic Analysis Indicator (SAI) for the sub-basins of the Sorocabuçu River (SRB), using a fuzzy system and geoprocessing tools for zoning information by sub-basins. The HDI of the SRB resulted in high values, with income showing the lowest indices, followed by education and longevity. The SII showed low values, with income and literacy significantly contributing to socioeconomic vulnerability. The SAI results indicated reasonable socioeconomic conditions, with lower values in the sub-basins farther from urban and urbanized areas. This study provides data for the establishment of public policies aimed at reducing social and economic inequalities, prioritizing the most vulnerable sub-basins. The data obtained serve as an effective tool to support public management, promoting decisions that improve the quality of life of the local population through the integration of socioeconomic variables for a more holistic and sustainable approach to watershed management.

Introduction: Brazilian spotted fever is an emerging zoonosis notified mainly in the Southeast of Brazil, especially due to its high level of lethality., Objective: To analyze the epidemiological and spatial pattern of the disease in the municipality of Valinhos (106,793 inhabitants), São Paulo, Southeastern region of Brazil, in the period between 2001 and 2012., Methods: All laboratory-confirmed cases with likely site of infection in the city (n = 49) notified in the Brazilian Case Registry Database were studied. Sites were geocoded using the cartographic base of the city and Google Earth (geographic coordinates) with correction according to the Brazilian Geodetic System. We used the Kernel estimator to analyze the density of the cases on the map. Land cover and distance to basins of all cases were analyzed. Information about tick species and primary hosts were obtained from reports of the Superintendence of Control of Endemic Diseases., Results: Seasonality of the disease was observed with the highest incidence from June to November, and in 2005 and 2011. The most affected groups were men (79.6%) aged 20-49 years old (49%). Lethality was found to be 42.9%. Maps showed the progressive registration of cases in the urban area. Capybaras were reported as the main primary host, and Amblyomma cajennense was identified in probable sites of infection during field investigation. The likely sites of infection were mostly located near basins, dirty pastures, and bordering woods., Conclusions: The transmission pattern of Brazilian spotted fever in Valinhos is similar to that in other cities in the region, where capybara is the main primary host and an amplifier of R. rickettsii. Over the years, a higher occurrence of cases has been identified in the urban area of the city.
