Article Synopsis
- - Heatwaves in Latin America are expected to become more frequent, longer, and more intense by mid-century, with even greater increases under the high emissions scenario (RCP8.5) compared to the low emissions scenario (RCP2.6).
- - The frequency of heatwaves may double across most of Latin America, leading to a significant increase in population exposure to extreme heat, projected to rise by three to ten times in Central and South America.
- - Following a low emissions pathway (RCP2.6) could significantly reduce heatwave exposure—by 57% in Central America and 50% in South America—emphasizing the need for emissions control and sustainable practices to mitigate climate change impacts. *
This paper examines scaling behaviors of urban landscape and street design metrics with respect to city population in Latin America. We used data from the SALURBAL project, which has compiled and harmonized data on health, social, and built environment for 371 Latin American cities above 100,000 inhabitants. These metrics included total urbanized area, effective mesh size, area in km2 and number of streets.

- Urban warming affects the health of city residents, particularly in the Global South, and its causes are not well understood.
- A study of 359 Latin American cities from 2001 to 2022 found that better economic conditions correlated with less urban greenness in 2011, leading to increased warming.
- Recent efforts to increase urban greenery partially mitigated this warming effect, especially in arid cities, highlighting the complex relationship between economic conditions, green space, and urban heat.
Green vegetation may protect against heat-related death by improving thermal comfort. Few studies have investigated associations of green vegetation with heat-related mortality in Latin America or whether associations are modified by the spatial configuration of green vegetation. We used data from 323 Latin American cities and meta-regression models to estimate associations between city-level greenness, quantified using population-weighted normalized difference vegetation index values and modeled as three-level categorical terms, and excess deaths from heat (heat excess death fractions [heat EDFs]).

However, little is known about area-level characteristics that confer vulnerability to temperature-related mortality.
Objectives: Explore city-level socioeconomic and demographic characteristics associated with temperature-related mortality in Latin American cities.
