  • Satellite images reveal a 15-degree Celsius temperature difference between the wealthy Morumbi neighborhood and the Paraisópolis favela in São Paulo, Brazil.
  • Researchers attribute this heat disparity to overcrowded housing, lack of ventilation, and inadequate basic services in favelas, turning homes into "ovens."
  • Urban planning decisions and a lack of investment in peripheral areas exacerbate environmental racism, creating "sacrifice zones" with extreme heat and few trees.

A stark 15-degree Celsius temperature gap separates the affluent Morumbi neighborhood from the Paraisópolis favela in São Paulo, Brazil, revealed through satellite imagery. While Morumbi's tree-lined streets hover around 30°C on a summer afternoon, crossing an avenue into Paraisópolis, home to over 58,000 residents, exposes one to surface temperatures reaching 45°C.

This dramatic disparity is not accidental. Research from the Center for Favela Studies (Cefavela) indicates that São Paulo's 1,359 favelas, housing 1.72 million people on just 4% of the urban territory, consistently experience average surface temperatures exceeding 40°C. Victor Nascimento, a researcher involved in the study, explained to EFE that densely packed concrete housing, metal or asbestos cement roofs, and a lack of cross-ventilation effectively turn homes into "ovens."

the heat extreme in the favelas "deepens the inequalities of environmental racism."

Combating the heat is further complicated by the scarcity of basic water and electricity services in many homes. Residents often resort to illegal connections, preventing them from using fans or even taking cooling showers. This precarious housing situation is compounded by flawed urban planning. According to the Climate Observatory, many cities make decisions that run counter to climate adaptation efforts.

The lack of investment in storm drainage, comprehensive environmental sanitation, and sustainable infrastructure in peripheral areas makes risk management fragile and leaves communities vulnerable to floods, landslides, and heatwaves. Thaynah Gutierrez, executive secretary of the Antiracist Adaptation Network, stated that extreme heat in favelas "deepens the inequalities of environmental racism." She noted that the city suffers a division between "sacrifice zones" in the periphery, devoid of trees and basic infrastructure, and wealthier neighborhoods that enjoy thermal balance and greenery.

the housing crammed with concrete, the roofs of fibrocemento or metal and the lack of windows for cross-ventilation turn the houses into "ovens."
