São Paulo metropolitan region experienced an acute water crisis between 2013 and 2015. According to the Brazilian and international press, it was due to climatic, anthropogenic, and water management factors. This paper assesses the hydro-climatic characteristics of the crisis by focusing on the Alto-Tietê basin and the headwater of the Piracicaba-Capivari-Jundiaí (PCJ) basin that supply 70% of the water consumed in the metropolis. Based on 16 rain-gauge stations, 5 runoff-gauge stations, and several statistical analyses carried over the 1951–2015 period, this assessment shows that the 2013–2015 hydro-climatic crisis resulted from a large number of days without rain in the north of the Alto-Tietê basin and to less intense precipitation events in the headwaters of the PCJ basin during the austral spring 2013 and the year 2014. It also defines a return period of 98 years for observed river flows in 2014. Despite the rare nature of this hydrological drought, the need for efficient water saving policies is brought forward.

The paper presents a discussion on the water crisis that occurred between 2013 and 2015 in the Metropolitan Region of São Paulo, the lack of integrated natural resources planning, and the reaction of social actors affected by the crisis. The region was affected by an extreme hydrological and climatological event, which was combined with the unsustainable management of water resources. The paper addresses, initially, the dynamics of water governance in the region, and the main aspects related to water availability and climate dependence that caused the water crisis. Then, we present an analysis of the process that led to the water crisis and its main developments, which is based on the follow-up of the different moments of the crisis and dialogues with its relevant stakeholders. The results indicate the relevance of emphasizing issues on matters such as the lack of transparency and highlight the role of societal initiatives. We conclude the paper with a proposition to discuss governance processes that can contribute to the development of more effective initiatives in order to reduce the impact of this visible change in water regimes, strengthen transparent management, and promote a more democratic interaction between social actors and the government.

Abstract Brazil's Southeast region has been facing water supply challenges, especially concerning the metropolitan region of São Paulo, since 2014. We adressed the water crisis from the disaster's point of view, considering that one of the guiding features to characterize a disaster is the amount of affected people and the losses associated. In the situation under review, there are people directly affected, because of intermittent house water supply, and indirectly affected by the increase of prices for goods, since their production and manufacturing depend on the availability of water. We presented each of the stages of a disaster risk management: prevention, mitigation, preparedness, response and recovery. The risk of water scarcity in São Paulo is only one aspect of the discussion involving the effectiveness of management processes and the need for investments in the area, especially in reducing wasteful distribution.

Background: Intracranial trauma (IT) is an injury inside of the cranial box resulting from external forces, usually caused by automotive accidents, falls and violence, sometimes leading to permanent damage or death. Objectives: Describe hospital admissions for IT in the metropolitan region of São Paulo (SP), based on ICD-10 morbidity list. Design and settings: Epidemiological, descriptive and retrospective study. Methods: Data provided from the Hospital Morbidity System (SIH-SUS) of the Ministry of Health, from January 2015 to December 2020. Results: There were 65.455 cases of hospitalizations by IT registered in the metropolitan region of SP, which surpassed the cases of the North and Midwest regions. In 2020, there was a 5% reduction in cases compared to 2019. The amount spent represented 10.5% of the total spent in Brazil. Most of the hospitalization patients were male, and the most affected age group was 40- 49 years. The lethality was 11.05% and higher in patients over 80 years-old. Conclusions: It is essential to control IT’s causing factors, since it engenders high costs, and it is a serious problem for the public health and economy, and for the victim’s psychosocial context. The metropolitan region of SP requires special attention, once it shows higher rates of hospitalizations, morbidity, and mortality than any other brazilian state. Despite the social isolation in 2020, there were no significant differences between this year’s records comparing to the other ones.

The Juréia Massif, southeastern São Paulo State (Brazil), is part of the Registro Domain, limited to the north by the Cubatão-Itariri Shear System and to the south by the Serrinha Shear Zone. Mostly composed of migmatitic granitegneiss rocks, represents a Paleoproterozoic terrane (1.9-2.2 Ga) strongly deformed during the Neoproterozoic (750-580 Ma). The present tectonic scenario was established at the end of the Neoproterozoic, as a result of collages associated with the formation of Western Gondwana. The Ponta da Juréia, our study area within the Juréia Massif, is constituted by paragneisses (garnet-muscovite-biotite gneisses). The monazite U-Pb age of 750 Ma is related to a main regional metamorphic event that reached the high amphibolite facies, recorded in rocks from the Itatins Complex and Cachoeira Sequence as well, which also belongs to the Registro Domain. The paragneissic rocks of this study are affected by the E-W-trending Serrinha Shear Zone, registering a predominantly dextral movement. Biotite K-Ar ages of 482 ± 12 Ma may represent later movements and reflect the younger ages of reactivation of the major lineaments and juxtaposition of the tectonic blocks involved.

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.
