Abstract From late 2013 until the beginning of 2015, the metropolitan region of São Paulo, Brazil, experienced a severe water shortage. During that period, economic incentives were implemented by the regional water provider in a successful attempt to reduce water consumption. We aimed to investigate whether such incentives, as well as the experience of a scarcity period itself, had a persistent impact on consumer behaviour after the water crisis was over. This study was conducted by means of a hierarchical linear model with three levels (HLM3) to verify if the reduction effect remained in the midterm and a regression using panel data to understand which factors influenced water consumption behaviour change before, during, and after the local severe water drought. The results indicate that the average water consumption level subsequent to the rain scarcity period was significantly lower than before and that, in addition to the economic incentives, the severity of the scarcity event explained the behaviour change verified in water consumption.

Abstract There are numerous studies regarding water pricing, demand and elasticity for certain regions. However, in Brazil, there are no studies on these matters, even though there is a need to explore the behavior of Brazil's population, especially because the nation is susceptible to extreme water events. São Paulo State, Brazil's most important economic region, has recently experienced a severe water scarcity status. In an attempt to control water demand, the São Paulo Water Agency (SABESP) implemented a ‘bonus and onus’ program. In this context, the aim of this study was to analyze the SABESP programs in terms of their structures and results using a panel model. The econometric results showed that (i) the bonus program was successful and more effective than the onus program, and (ii) water consumption reduction was more significant in regions supplied by water reservoirs where the relative water level was lower, although inhabitants of other regions also reduced their water consumption.

In 2015, the water crisis affecting the São Paulo Metropolitan Region reached its peak. The Federal Government published an Ordinance stablishing good practices in the management and use of water and electricity. This work aimed to verify if the management actions performed at the Universidade Federal de São Paulo were effective for water consumption reduction. It was analyzed secondary data of the monthly water consumption at campuses and Rectory, from 2014 to 2016. Statistical analyses were carried out comparing the water consumption between the periods pre- and post-intervention, which occurred in February 2015. The results show that the intervention reduced per capita water consumption by 33% in 2015 and 35% in 2016, saving up more than 65,000 m3 of water. These management actions were effective, and helped the academic population to achieve a more efficiently use of water and financial resources, becoming more sustainable.

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.
