“…Indexes of segregation, from the dissimilarity index to composite indicators of segregation's dimension (evenness, exposure, concentration, centralization, clustering, isolation, and their pairwise combination) or spatial distribution indexes (see, for instance, Massey and Denton 1988;Hogrebe and Tate 2019;Yao et al 2019;Cruz-Sandoval et al 2020;Najib 2020) are computed on data of population counts by race, number of children, education, income and other proxies of class segregation, e.g. socioeconomic vulnerability indexes (Martines et al 2020). Census data are basically available at aggregated spatial scales (e.g.…”

Initially considered a ‘luxury’ good and now becoming a more popular and diffused landmark, the spatial distribution of residential swimming pools reflects the socio-spatial structure in Mediterranean cities, offering a kaleidoscopic overview of class segregation and economic disparities. The present study hypothesizes that economic downturns, resulting in alternative phases of social polarization and mixing, affect the spatial distribution of pools. To verify this assumption, the spatial distribution of pools in Athens, Greece—a city with evident social disparities and largely affected by the great recession—was analysed during the most recent expansion and recession. Results shed light on the spatial linkage between pool density, class segregation and dispersed urban expansion in a context of rising income disparities. The spatial distribution of swimming pools became increasingly polarized in the Athens’ metropolitan region. The spread of residential pools in wealthier districts suggests how recession has consolidated disparities between rich and poor neighbourhoods. Based on the empirical findings of this study, pools can be considered a proxy of increased socio-spatial disparities reflecting class segregation and economic polarization at the local scale.

O artigo tem como proposta analisar a segregação residencial da área urbana do 1º distrito de Campos dos Goytacazes, município localizado na Região Norte do estado do Rio de Janeiro, considerando-se as áreas dos subdistritos como unidades de análise. Para o estudo, adotou-se uma metodologia de análise da segregação associando índices não espaciais (índices de dissimilaridade e de isolamento) com a estatística espacial a partir da construção do mapa de calor, funcionalidade disponível no software de Geoprocessamento Quantum GIS. Utilizou-se, como variável, o domicílio particular permanente, segundo as classes de rendimento nominal mensal domiciliar per capita. A partir dos resultados obtidos, ficou evidenciado que o 3º subdistrito apresenta a área mais segregada, onde estão mais concentrados os grupos de menor renda, enquanto o grupo de maior renda concentra-se no 1º e no 2º subdistritos.

“…However, with the industrial revolution, unrestrained urban growth became one of the main factors for reducing the resilience of cities (Moreira and Vitorino, 2019). The suppression of natural ecosystems had generated different environmental problems, such as the increase in heat islands, air pollution, floods, among others (Foloni and Constantino, 2016;Martines et al, 2020). Due to climate change, the effects of these problems are going to be strongly noticed in a local scale (IPCC, 2013;PBMC, 2016).…”

The growth of the urban population promotes a strong pressure to occupy open spaces in urban center, including around watercourses. Canalization and drainage techniques favored urban expansion and occupation of these spaces. In long term, this has not been efficient, since it is not a sustainable decision, mainly in view of the challenges provided by climate change. The purpose of this work was to analyze the modification of the landscape and multifunctionality of the urban watercourses in relation to socioeconomic and environmental scope of the evolution of an urban area using Lavras city, Brazil, as model. For that, city's hydrographic grid was drawn from the digital elevation model (DEM) corrected by manual vectorization after field visits and analysis of high-resolution images. To understand natural and sociocultural evolution processes, a compilation of geo-historical information about the origin and formation of the city was made using Patchwork Quilt methodology. To understand the actions and perceptions of different actors from urban watercourses in Lavras, questionnaires were applied to the population, and interviews were directed to the public and private managers. It was observed that the watercourses and their surroundings lost a large part of their natural, social, and economic functions, after the 1980s, only having a drainage function. The areas in expansion prioritize the natural function preservation but lack the incentive to implement the other functions such as social and economic. With the economic valuation of land, the implementation of green and blue infrastructure has not yet been prioritized. Even with the legislation that provides multifunctional uses for rivers and their banks, the urban watercourses from Lavras remained largely monofunctional. This did not contribute to increasing the city's green areas and the reintegration of watercourses into the urban landscape. The population values the water present in the urban landscape and yearns for multifunctional solutions such as green areas and urban gardens. Public and private actors recognize the lack of clarity in the legislation, and in the definition of concepts and techniques to be adopted. Multifunctional solutions can be in favor of reconciling different interests, promoting the reintegration of rivers into the urban landscape.
