Tillandsia usneoides is an epiphytic bromeliad that has been used as a universal bioindicator. The species accumulates metals and presents foliar scale variations when exposed to air pollutants. This study aimed to use the variations in foliar scales as microscopic markers of pollutant effects in the Metropolitan Region of Campinas (MRC), São Paulo State, Brazil. T. usneoides plants were exposed for 12 weeks during dry and wet seasons, totaling four exposures, at five sites in the MRC. Samples were selected before each exposure for initial evaluation of the plants (T0). Leaf fragments were fixed in glutaraldehyde and total scale density and anomalous scale percentage were evaluated. Plants exposed in the MRC showed anomalies and changes in number of subperipheral cells of leaf scales. When compared to T0, T. usneoides presented higher total scale density and anomalous scale percentage at disturbed sites, thus the species can be used as a pollution bioindicator for MRC.

This article investigates the application of economic indicators for the parametric estimation of public transportation aggregate demand. Since the transportation sector plays as vital role in a city infrastructure the objective is to present a method of selecting economic indicators that assist in the study of urban public transport demand, taking as a case study the Metropolitan Region of São Paulo (MRSP). Using econometric modelling, it was estimated the effect of variables explaining total traffic in the transport system, and more specifically examine the role of fares and the employment and wage indicators. Statistical tests were performed to check the validity of the analyzed models and develop a rank of indicators according to their performance as regressors. The subset of indicators that were representative of industrial activity and more related to the local economy had the best performance as a forecasting tool.

A presente análise objetivou avaliar as ações de planejamento e gestão do Turismo em áreas naturais protegidas da Região Metropolitana da Baixada Santista (RMBS) no Estado de São Paulo (Brasil), identificando em que nível estas ações foram influenciadas por conceitos e métodos propostos em dois programas mundiais da Organização das Nações Unidas (ONU): os Objetivos do Desenvolvimento do Milênio (ODM) e a Convenção sobre Diversidade Biológica (CDB). Enquanto a CDB já é amplamente difundida em programas de manejo e gestão do Turismo em áreas protegidas no Brasil, os ODM tiveram pouca penetração nesta temática. Subdivididos em oito metas globais, quatro delas têm amplo potencial para contribuir na elaboração de novas metodologias na gestão do Turismo em áreas naturais protegidas: o ODM 01 (redução da fome e da miséria); o ODM 03 (promoção da igualdade de gênero); o ODM 07 (respeito ao meio ambiente) e o ODM 08 (estabelecimento de parcerias para o desenvolvimento sustentável). Como resultado, a pesquisa demonstrou haver influência apenas indireta das metodologias propostas pelos ODM no que tange ao planejamento e gestão de atividades turísticas sustentáveis nas áreas naturais protegidas da RMBS, enquanto a influência da CDB foi facilmente identificável nas políticas e ações de planejamento e gestão do Turismo. Foram alcançadas algumas conclusões, como por exemplo, a de que os ODM passaram por uma clara adaptação ao contexto brasileiro por meio de políticas públicas, preferencialmente com relação ao ODM 01 (redução da pobreza). Quanto ao ODM 07, no qual o Turismo Sustentável insere-se como atividade econômica a ser incentivada na elevação do nível de renda das populações locais e em prol da conservação ambiental, este carece fortemente de políticas públicas assertivas. Sendo colocado pela ONU como primordial para o sucesso dos ODM em países em desenvolvimento, o Turismo Sustentável com base nos ODM e na CDB pode proporcionar significativos ganhos a áreas como a RMBS, permeada por complexas configurações urbanas, ambientais e sociais. Influence of global programs on the sustainability of tourism in protected areas of the metropolitan area of Baixada Santista (SP, Brazil) ABSTRACT This analysis aims to evaluate the action planning and management of tourism in protected natural areas of the Santos Metropolitan Region (RMBS) in the State of São Paulo (Brazil), whilst identifying at what level these actions were influenced by concepts and methods proposed in two global programs of the United Nations (UN): the Millennium Development Goals (MDGs) and the Convention on Biological Diversity (CBD). While the CBD is already widespread in management programs and management of tourism in protected areas in Brazil, the MDGs have had little penetration on this theme. Subdivided into eight global goals, four of them have vast potential to contribute to the development of new methodologies in the management of tourism in protected natural areas: the ODM 01 (reducing hunger and poverty); MDG 03 (promoting gender equality); MDG 07 (respect for the environment) and the MDGs 08 (establishment of partnerships for sustainable development). As a result, the survey showed that there was only indirect influence of methodologies proposed by the MDGs with regards to planning and management of sustainable tourism activities in protected natural areas of RMBS. While the influence of the CBD was easily identifiable in policy and action planning and tourism management, some conclusions were reached, including the MDGs passing by a clear adaptation to the Brazilian context through public policies, preferably in relation to the MDGs 01 (poverty reduction). As for the MDGs 07, in which Sustainable Tourism is inserted as an economic activity to be encouraged in raising the income level of local populations while conserving the environment, this strongly lacks assertive public policy. It has been placed by the UN as paramount to the success of the MDGs in developing countries Sustainable Tourism based on the MDGs and the CBD can provide significant gains in areas such as RMBS, permeated by complex urban, environmental and social settings. KEYWORDS: Millennium Goals; Biological Diversity; Sustainable Tourism; Protected Areas; Local Communities.

During 18 years of experience in graduate education in the environmental area, the graduate programs in environmental sciences of the University of Taubaté have been consolidating the treatment of environmental issues in different geographic conditions, associated with the development of the metropolitan region of Vale do Paraíba, São Paulo, as well as environmental issues in the Amazon region. This edition of Ambi-Água presents 15 original articles from dissertations presented in the last three years, which reinforce the challenge in the treatment of environmental issues in an interdisciplinary context. The commitment of the PPGCA in the construction of knowledge in the environmental area that must guide the development of this important metropolitan region of the state of São Paulo is well known.

Este trabalho expõe onze evidencias de que o ritmo semanal das atividades humanas é um elemento significativo para explicar o sistema climático da Região Metropolitana de Sáo Paulo. Embora sugestivos, os resultados não são conclusivos, dada complexidade do próprio objeto, o clima, e a multiplicidade de hipó­teses em investigação em climatologia e meteorologia sob diversas abordagens metodológicas, espaciais e temporais. A conclusão deste trabalho é, tão somente, que o tema merece ser estudado com maior profundidade e maior abrangência espacial e temporal, exigindo o concurso de um montante de trabalho exeqüível apenas se realizado coletivamente. A principal e mais importante conclusão que pode advir de maior investigação do tema no futuro, e que já está expressa neste trabalho, é que parte das "alterações climáticas" imputadas à ação humana sobre o planeta, sobretudo em áreas urbanas, tem um caráter reversível em prazos muito curtos possivelmente semanas ou meses)

Abstract The 2013–2015 drought in the Metropolitan Region of São Paulo exposed the lack of resilience of the regional water supply system, highly dependent on the Cantareira reservoirs. In this paper, inflows to each of the four main Cantareira reservoirs are tested for systematic change. Persistent trends in streamflow, rainfall, temperature and evapotranspiration are first evaluated. Streamflow was also tested for step change. Double-mass curves were employed to assess modification in the precipitation–runoff relationship. Subsequently, we used the climate elasticity method and the ABCD model to quantify the relative contribution of climate and human activities into the detected trends. Only Cachoeira and Atibainha sub-basins showed a significant downward trend in streamflow. The results for step change were also significant, and the year of occurrence coincided with breakpoints in precipitation–runoff relationship. For both Cachoeira and Atibainha, human activities had a more significant impact on streamflow reduction than climate variability. Land use and cover maps suggest that the reduction of pasture/abandoned land parallel to an increase in reforestation/silviculture is behind streamflow reduction. The results highlight the importance of coordinating land-use patterns and water management, as an important contributor beyond any considerations of a changing climate. Implications for better managing regional water resources are discussed.
