This paper explores the scope for upscaling and transnational transfer of participatory landslide risk management strategies for informal settlements in Latin America. Drawing on lessons from transdisciplinary action-research in three neighbourhoods in Medellín, Colombia, and one in São Paulo, Brazil, the paper discusses how bottom-up approaches were developed to co-produce landslide risk management in both Global South cities, in a way that optimises the collaboration between communities and relevant governmental bodies. The analysis focuses on mitigation and 'agreement-seeking', from the perspectives of scale, power and knowledge, which help understand the parallels between co-production of landslide risk management and co-production of urban services. Two key conclusions are that landslide risk management should be built into neighbourhood upgrading and management, and that both community and the state have stronger roles to play in landslide risk management from their respective capacities. The paper also reflects on the role of academia in enabling co-production of landslide risk management through engaging with local communities. [ABSTRACT FROM AUTHOR]

Most transport equity and transport-related social exclusion (TRSE) studies assume that increasing accessibility levels lead to increased activity participation and, therefore, a reduction in social exclusion. Although this assumption makes sense from a theoretical point of view, this causal relationship has not yet been validated in practice. Previous studies investigating the accessibility-participation relationship were inconclusive, indicating that increasing accessibility has a limited impact on activity participation levels, if any. Moreover, the existing empirical evidence in the literature in the Global South context is scarce, is merely correlational and fails to infer causality between both variables. The contributions of the paper are threefold. First, (a) to provide a conceptual model of the causal relationship between accessibility, activity participation and risk of transport-related social exclusion (TRSE); second, (b) to summarise the available empirical evidence about the accessibility-activity participation relationship through a systematic literature review; and third, (c) to provide evidence of the causal relationship between accessibility and activity participation levels in a Global South context. Three Poisson regression models associated with an instrumental variable identification strategy were used to assess the causal effect between accessibility and participation in total, mandatory and discretionary activities in the city of São Paulo, Brazil. The three models showed a highly significant, strong correlation between an individual's accessibility level and their actual participation in total, mandatory and discretionary activities. Models that ignore the possible endogeneity present in the relationship between accessibility and activity participation may underestimate the effect of accessibility. Based on our results, we argue that low accessibility levels may severely restrict individuals' life chances and add evidence that accessibility has to be an important instrument to support transport policies' decision-making.

This paper reflects on the trajectory of Fernão Bracher in the light of institutional advances in the Brazilian public administration since the re-democratization of 1985 onward. Descendant of a traditional family in São Paulo, Bracher will channel his public spirit and his economic nationalism in three opportunities, notably during the postmilitary regime period, when he governed the Central Bank of Brazil and later became, at the invitation of his friend and minister Luiz Carlos Bresser-Pereira, the Brazilian negotiator of the external debt. Less theoretical than Bresser but as pragmatic as him, Bracher shared his friend's immense intellectual curiosity, having helped in the exchange of reflections among the different economists involved with the theory of inertial inflation. A man of action, in the private and public sectors, Bracher has a trajectory that highlights the overcome of difficulties present in national economic policy. [ABSTRACT FROM AUTHOR]

This paper contributes to the study of climate change and environmental justice with a particular focus on a Global South case-study in the São Paulo Macro Metropolis of Brazil. We also aim to contribute to mandatory critical dialogue between (anticipatory) governance and environmental justice. This study focuses on the rainy seasons from 2016 to 2019. We examine the incidence of 61 extreme precipitation events, as well as 47 deaths caused by rain events, considering their location based on vulnerability indicators. The correlations among these data allow us to reveal the socio-environmental patterns within the relationships between social vulnerability and deaths caused by general rainfall and, more specifically, extreme events. Based on this, we demonstrate that current infrastructure or its lack is one of the reasons why death tolls remain due to the absence of anticipatory governance. [ABSTRACT FROM AUTHOR]

• A model based on cellular automata and ordinary differential equations is proposed for dengue. • The spatial dynamics of the disease is studied with the coexistence of two serotypes. • A methodology for a spatial basic reproduction (R 0 s) number is proposed. • The model is applied for a neighbourhood in São Paulo, Brazil. • R 0 s was assertive in showing areas with a higher disease incidence. Background and objective: Dengue fever is a disease in which individuals' spatial distribution and Aedes aegypti mosquitoes breeding places are important factors for the disease dynamics. Typically urban, dengue is a problem for least developed countries due to the ineffectiveness in controlling the vector and disorderly urbanization processes. The result is a composition of urban sanitation problems and areas with high demographic densities and intense flows of people. This paper explores the spatial distribution of vector breeding places to evaluate introducing a new dengue serotype to a population at equilibrium for a pre-existing serotype. The paper's objective is to analyze the spatial dynamics of dengue using variations of the basic reproduction number. Methods: A model based on probabilistic cellular automata is proposed to permitting the necessary flexibility to consider some spatial distributions of vector breeding places. Then, ordinary differential equations are used as a mean-field approach of the model, and the basic reproduction number (R 0) is derived considering the next-generation matrix method. A spatial approach for R 0 is also proposed, and the model is tested in a neighbourhood from the city of São Paulo, Brazil, to examine the potential risks of vector breeding cells distribution. Results: The results indicated that the more spread out these places, the higher are the values of R 0. When the model is applied to a neighbourhood in São Paulo, residential areas may boost the infections and must be under public vigilance to combat vector breeding sites. Conclusions: Considering the mean-field approximation of the cellular automata model by ordinary differential equations, the basic reproduction number derived returned an estimative of the disease dynamics in the population. However, the spatial basic reproduction number was more assertive in showing areas with a higher disease incidence. Moreover, the model could be easily adapted to be used in real maps enabling simulations closer to real problems. [ABSTRACT FROM AUTHOR]

This comparative case study examines community self-governance in informal settlements in São Paulo, Brazil, through the Policy Arrangement Approach. Drawing on participant observation and semi-structured interviews, I highlight the importance of context in shaping self-governance and outcomes. Self-governance embodies power and politics, often not contained to the spatial boundaries of the informal settlements, and developed through intersecting nodes of people, organizations, institutions, resources, spaces. Ultimately, this study questions the notion of self-governance as a simplistic binary to propose self-governance as a dialectical continuum of self/non-self, recognizing the realities of governing communities as multiple, complex, and fluid.

Smart card data (SCD) allow analyzing mobility at a fine level of detail, despite the remaining challenges such as identifying trip purpose. The use of the SCD may improve the understanding of transit users' travel patterns from precarious settlements areas, where the residents have historically limited access to opportunities and are usually underrepresented in surveys. In this paper, we explore smart card data mining to analyze the temporal and spatial patterns of the urban transit movements from residents of precarious settlements areas in São Paulo, Brazil, and compare the similarities and differences in travel behavior with middle/high-income-class residents. One of our concerns is to identify low-paid employment travel patterns from the low-income-class residents, that are also underrepresented in transportation planning modeling due to the lack of data. We employ the k-means clustering algorithm for the analysis, and the DBSCAN algorithm is used to infer passengers' residence locations. The results reveal that most of the low-income residents of precarious settlements begin their first trip before, between 5 and 7 AM, while the better-off group begins from 7 to 9 AM. At least two clusters formed by commuters from precarious settlement areas suggest an association of these residents with low-paid employment, with their activities placed in medium / high-income residential areas. So, the empirical evidence revealed in this paper highlights smart card data potential to unfold low-paid employment spatial and temporal patterns. [ABSTRACT FROM AUTHOR]

Like many cities in developing countries, São Paulo, Brazil, is characterized by major intra-urban inequalities with respect to human development. The center-periphery spatial regimes are the most obvious spatial manifestation of this phenomenon. In this paper we apply confirmatory spatial data analysis to examine these inequalities and their relationship to public interventions. Using district-level data, we examine the relationship between public interventions and the level of human development, while controlling for population density, spatial heterogeneity and spatial autocorrelation. Our results suggest that public interventions reinforce the existing differences between center and periphery. Specifically, public services and utilities and social programs are allocated more intensively in districts with higher human development levels. These findings call for a more careful consideration of distribution of societal resources and effectiveness of public programs and policies. [ABSTRACT FROM AUTHOR]

This paper analyzes the perceptions of journalists in São Paulo, Brazil's main media hub, concerning media roles, ethics and foreign influences on journalism and compares them with perceptions held by American and French journalists. American and French models of journalism have influenced Brazilian journalism at different points in time. The study employs quantitative and qualitative methods to illustrate that Brazilian journalists embrace a particular pluralistic view regarding their role in society and appear to be very tolerant of controversial journalistic practices. While most of them believe they emulate the American model, some critics interviewed for this study suggest that these journalists have developed a caricature of American journalism and lack a clear perspective on how to deal with foreign journalistic influences.

As adolescents get older, they become more evening oriented and, because they are usually expected to wake early to attend school, they often present daytime sleepiness, which is associated with negative outcomes. It is still unclear if this is similar cross-culturally. Here, we studied morningness-eveningness and daytime sleepiness in early adolescence from two different developing nations (Brazil and Iran). A total sample of 697 Iranian and Brazilian early adolescents (9- to 15-year-old; 358 boys) from Tehran, Iran, and São Paulo, Brazil, varying in age and parental schooling (a proxy of socioeconomic status: SES) completed the Morningness–Eveningness Scale for Children (MESC) and the Pediatric Daytime Sleepiness Scale (PDSS) and reported their total sleep time on school nights. They also filled in the Pubertal Developmental Scale to determine their pubertal status. A negligible cross-cultural difference in morningness-eveningness was found, indicating that Brazilians showed a slight circadian-phase delay compared with Iranians throughout all tested ages. There was also seen a very slight increase in phase delay as early adolescents aged, indicative of more eveningness. However, there were no country differences in daytime sleepiness once total sleep time during school nights was controlled for, which was the only factor that affects PDSS scores.

Water quality monitoring networks (WQMNs) are essential to provide good data for management decisions. Nevertheless, some WQMNs may not appropriately reflect the conditions of the water bodies and their temporal/spatial dimensions, more particularly in developing countries. Also, some WQMNs may use more resources to attain management goals than necessary and can be improved. Here we analyzed the São Paulo State (Brazil) WQMN design in order to evaluate and increase its spatial representativeness based on cluster analysis and stratified sampling strategy focused on clear monitoring goals. We selected water resources management units (UGRHIs) representative of contrasting land uses in the state, with bimonthly data from 2004 to 2018 in 160 river/stream sites. Cluster analysis indicated monitoring site redundancy above 20% in most of the UGRHIs. We identified heterogeneous spatial strata based on land use, hydrological, and geological features through a stratified sampling strategy. We identified that monitoring sites overrepresented more impacted areas. Thus, the network is biased against determination of baseline conditions and towards highly modified aquatic systems. Our proposed spatial strategy suggested the reduction of the number of sites up to 12% in the UGRHIs with the highest population densities, while others would need expansions based on their environmental heterogeneity. The final densities ranged from 1.6 to 13.4 sites/1,000km2. Our results illustrate a successful approach to be considered in the São Paulo WQMN strategy, as well as providing a methodology that can be broadly applied in other developing countries.

This article examines water crises in three megacities (São Paulo, Rio de Janeiro, and Jakarta) in the Global South. While crises can delegitimize the dominant water policy and lead to policy change, this does not necessarily come about in all cases. Drawing data from key informant interviews, newspaper articles and policy documents, and using Steven Lukes' three faces of power framework, we observe how crisis framing has reinforced large infrastructures for water supply and flood protection. In the three case studies, powerful actors combined the three faces of power to shape public opinion in pursuit of their own agendas. [ABSTRACT FROM AUTHOR]

This paper evaluates the impacts of a policy that introduced a sizeable wage premium (24% to 36%) to teachers at disadvantaged schools on teacher turnover in the public school system in São Paulo, Brazil. We explore a discontinuity at the eligibility rule to identify the policy effect. We find that the wage compensation reduced turnover by 5 p.p. (10.4 % over the pre-treatment average). We also show that this policy positively impacted the achievement of low-performing students, but had no effects on average test scores. We rule out alternative explanations, such as reallocation of teachers or direct effects of the wage increase. These results suggest a disruptive effect of teacher turnover on learning, especially on students at the bottom of the test score distribution. [ABSTRACT FROM AUTHOR]

Accessibility metrics have been increasingly employed as a tool to explore the social impacts of transport systems and policies. However, few empirical studies of accessibility involve comparisons between cities from countries with different levels of development, in particular, across the Global South and North. This paper attempts to bridge this gap by focusing on two very distinct, but similarly sized, large metropolitan regions: São Paulo and London, for which we develop comparative metrics. These metrics are used to identify patterns for different occupational groups (used as a proxy to socioeconomic groups) and discuss transit accessibility inequalities. The issues imposed by a comparative study of urban regions with particular characteristics are discussed. The study applies the results of one metropolitan region to contrast with the other and explore how characteristics of each region's public transport system and spatial mismatch between residential and workplace locations are related to inequalities. Group's condition was represented in the Lorenz curve, also revealing a new strategy to be adopted by comparability studies on inequalities. The results from Lorenz curve and Gini coefficient reveal larger transit accessibility inequalities in São Paulo than London. The proposed group representation enriched the comparability perspective as a tool to support transport planning. • Public transport inequalities comparison across Global South and North metropolitan regions • Accessibility metric adapted for social groups analysis • New strategy to capture groups inequalities on comparative studies • Empirical study reveals accessibility inequalities from São Paulo and London cities.

In developing countries, there is often a lack of a comprehensive data set that support s the development of coherent policies on resource recovery from wastewater treatment. This paper aims to contribute to the elaboration of resource recovery projects by providing accurate and updated data from wastewater treatment plants such as those located in the region of the Macrometropolis of Sao Paulo. The authors discuss possibilities of improvement of resource recovery for this illustrative example. Comprehensive analyses were performed based on data from 143 municipal wastewater treatment plants to understand the situation regarding resource recovery implementation in this region. The results show that just 26% of the plants perform at least one resource recovery practice. The predominant resource recovery practice is internal water reuse, and recovery is concentrated more in large plants than in medium and small ones. The sludge is disposed in landfills except for three plants, which perform sludge recycling for compost. Some plant managers reported interest in recovering energy from biogas, in expanding water reuse and in recovering sludge for fertilizer production or for building materials. Several aspects that have been regarded as relevant to the implementation of resource recovery processes in previous literature are discussed, such as the size of the plant, related legislation as well as treatment technologies and configurations. Finally, the authors propose a generic framework with several steps that can help to achieve resource recovery implementation. Therefore, the results can provide support for planning of resource recovery projects for large cities in developing countries. Image 1 • Megacities in developing countries face severe water and sanitation challenges. • Reliable data for resource recovery plans of wastewater treatment plants are rare. • A survey collected data from 143 plants for comparison with the literature. • Barriers and opportunities for resource recovery in Sao Paulo were identified. • The proposed framework facilitates planning of future resource recovery projects.

Real-time (RT)-PCR increases diagnostic yield for bacterial meningitis and is ideal for incorporation into routine surveillance in a developing country. We validated a multiplex RT-PCR assay for Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae in Brazil. Risk factors for being culture-negative, RT-PCR positive were determined. The sensitivity of RT-PCR in cerebrospinal fluid (CSF) was 100% (95% confidence limits, 96.0%-100%) for N. meningitidis, 97.8% (85.5%-99.9%) for S. pneumoniae, and 66.7% (9.4%-99.2%) for H. influenzae. Specificity ranged from 98.9% to 100%. Addition of RT-PCR to routine microbiologic methods increased the yield for detection of S. pneumoniae, N. meningitidis, and H. influenzae cases by 52%, 85%, and 20%, respectively. The main risk factor for being culture negative and RT-PCR positive was presence of antibiotic in CSF (odds ratio 12.2, 95% CI 5.9-25.0). RT-PCR using CSF was highly sensitive and specific and substantially added to measures of meningitis disease burden when incorporated into routine public health surveillance in Brazil.

Currently, it is important to develop strategic frameworks to support the selection of sustainable resource recovery solutions. This study applies a new framework for planning, implementation, and assessment of resource recovery strategies for a full-scale wastewater treatment plant (WWTP) in São Paulo megacity. The framework comprises several steps based on case study-specific data and information from current literature. Data were collected from various sources: a survey with a wastewater treatment utility, national and regional databases, and review of local regulations and international literature. Treatment configuration, wastewater and by-products composition, potential demand (for water, energy, and phosphorus), stakeholder identification, and local legislation were thoroughly discussed regarding decision-making on resource recovery. Scenario analysis was used to explore suitable nutrient and energy recovery measures based on indicators. Biogas recovery and sewage sludge composting showed more favorable conditions due to similar experiences in the area and robust legislation. The proposed framework is a simplified tool, and its application can support managers to get information on resource recovery and how to plan such initiatives in easier ways to facilitate wiser decision-making, and better operation and management. The results on framework use and refinement can guide potential applications in other contexts and stimulate public policy formulation and further research. [ABSTRACT FROM AUTHOR]
