O cultivo de citrus é uma das principais atividades agrícolas no Estado de São Paulo, sendo realizado em solos gerados a partir de diferentes materiais que conferem, naturalmente, variações na constituição química e mineralógica destes, além de poderem, ou não estar contaminados por metais tóxicos oriundos dos métodos defensivos. Com o objetivo de quantificar os atributos químicos e os teores de metais pesados do solo foi realizado um estudo comparativo entre solos assim cultivados, das regiões das cidades de Mogi Guaçu e São José do Rio Preto. Este estudo envolveu a determinação do pH do solo, análises volumétricas para quantificação dos teores de matéria orgânica, Ca+2, Mg+2 e Al+3 , espectrofotômetro de chama para o estabelecimento dos teores de Na+ e K+ e espectrofotômetro de absorção atômica para determinação dos teores de Cobre, Zinco, Cádmio, Cromo, Níquel e Chumbo. O solo da região de Mogi Guaçu apresentou-se mais ácido devido, provavelmente, a uma maior concentração de Al3+. Apresentou, também, teores mais elevados de matéria orgânica. Os solos de ambas as regiões apresentaramse deficientes em Na+ , K+ , Ca+2 e Mg+2 . A análise realizada para os metais pesados mostrou uma elevada quantidade de Níquel observada nas amostras de solo da região de São José do Rio Preto e, Níquel e Cobre, nas de Mogi Guaçu, com valores classificados como de prevenção, de acordo com os Parâmetros Orientadores da CETESB (2005). Estes teores de alerta devem-se, muito possivelmente, à adição exagerada de defensivos agrícolas.

Beekeeping is recognized as promoter of assumptions and dimensions of sustainable development, supported by the triple bottle line – economic viability, social relevance and environmental prudence. Historically, it is strongly related with the central state of São Paulo. This work has as main objective to identify the profile of beekeeping in the this region, based on four municipalities (Araraquara, Descalvado, Rio Claro and São Carlos) in order to determine the main difficulties faced by beekeepersfor the sustainable development, pointing alternative interventions able to soften the effects of difficulties. It was used two different and complementary methodological strategies. The first one was a search with the databases (SEADE and IBGE) to obtain secondary data and quantitative regarding beekeeping in the region. The second one, it wasthrough field research with the beekeepers. The survey found that beekeeping in the region, presents an essentially familial and hereditary. Was also noticed the damage caused in the production, by limiting access to the region’s bee pastures and use of pesticides. In processing, it was found the extremely precarious conditions. At the institutional level, it was found the relative weakness of the beekeepers cooperatives, and the lack of support from local governments to consolidate activity.

This paper provides an overview of the key findings of a survey that sought to examine the relationship between local government agencies and agrarian reform communities in the State of São Paulo, particularly with regard to the types of support that have been provided by these agencies to the economic activities of settlements. The research was part of the project "The agencies and services involved in the implementation of public policies for equity and growth", which was supported by the Instituto de Colonização e Reforma Agraria (INCRA/SP), whose activities were carried out throughout 2011. In methodological terms, the research was divided into two stages. In the first stage, it sought to identify the main economic activities, vocations and potential of the influencing areas of the Quilombola communities and settlements in their respective regions and micro-regions. Therefore, a survey was conducted based on secondary data. In the second stage, a qualitative, exploratory, empirical, and multiple case study research was conducted. Local public officials, in charge of the institutional relations with the agrarian reform settlements (and quilombolas communities, in this case, one of the municipalities investigated) were the primary source of data for this analysis that sought to evaluate the strength, types and quality of support (plausible or effective) provided by the municipalities to the economic activities of settlements. The results indicated a set of reasonably heterogeneous components, and frequently, distinct, of particular circumstances. Based on the results some proposals for action plans were indicated, which probably would constitute a standard reference for the formulation and implementation of public policies and actions to improve the economic activities of the settlements.

This article aims to rank the main concepts in vogue in the city of São Paulo who contributed to the formulation of a shared urban oriented capitalist development and reproduction of the workforce. This way, it will discuss the main issues raised in the period, which is between the first decades of the XX Century to the end of the 1950s, trying to foresee how they worked as engineers and architects to incorporate the urbanistic proposals from Europe and the United States. And then, we will present, on the first four sections of this article, points of view that effectively impacted the paulista urban thought of the first half of the XX century: Sanitarism, pendular conception between the Mesologic Theory and the Microbian Theory; the Historicist formulation of Camillo Sitte; Howard´s garden-town and The French Experience. Our analyses were formulated having as a reference the broad systematization of bibliography and documents performed at the Arquivo Histórico Municipal (Intermediário) de Araraquara (Historical Municipal Archive from Araraquara), consultations at the the books of the library of the biblioteca da Faculdade de Arquitetura e Urbanismo da USP (USP Architecture and Urbanism College) and at the Faculdade de Ciências e Letras da UNESP, Araraquara-SP( College of Sciences and Languages from UNESP, campus Araraquara). The analisys of the performed research show that one urbanistic torrent at São Paulo State with clear influences from the conceptions that led the urbanistic debates in the first half of the XX Century. Although these conceptions compose a painting of urban transformations at São Paulo city and noticeably in some inland cities, previously to the solidification of a whole proposition for the city that was later called of Directive Plan.
