A survey carried out by the Redes da Maré in 16 favelas shows that there is a difference of up to 2 ºC in temperature between the regions of the complex

Between March and September, environmental agents from the Respira Maré project collected data that identified not only the hottest areas of Maré (a suburb of Rio de Janeiro), but also those with the highest indices of pollution. In November, with the support of iCS, the “Diagnosis regarding Heat Islands and Air Quality in the 16 favelas of Maré” was published. It showed, for example, a temperature difference of 2 ºC between the hottest point, in Nova Maré (28.3 ºC) and the coolest, in Nova Holanda (26.4 ºC). This is evidence of the formation of internal heat islands.

The survey was presented at the seminar ‘Understanding the Climate Risks in Maré: the current situation and what we can do,’ carried out by the Redes da Maré. The research also shows that the concentrations of particles from pollutants and dust in the air vary from moderate to critical in the region. The territory is located between the three main access roads of Rio de Janeiro (the Linha Vermelha, the Linha Amarela and Avenida Brasil) and it consequently suffers from significant atmospheric pollution.

The entire diagnosis was supported by the Laboratory of Computational Methods in Engineering (LAMCE), of the Alberto Luiz Coimbra Institute of Postgraduate Studies and Research in Engineering at UFRJ. The proposal of Redes da Maré is to use the data from the survey to promote public policies that include solutions for the communities.

“We ended up creating a methodology that can be used in organizations, universities and, in particular, by the government, to look at the problems that each territory produces. We still have a significant difficulty today in mediating the subject of the environment in the favela, seeing as we only concentrate on basic sanitation. There is much more than this,” recalls the coordinator of the Urban and Socioenvironmental Rights area, Shirley Rosendo, in an interview with the Redes da Maré website.
