Authorities in Brazil's Federal District approved a plan in December 2025 to cut the "green deficit" in poorer outlying areas such as Sol Nascente (a favela of over 70,000 people about 30 km from central Brasília), where tarmac and sparse trees help push dry-season temperatures in nearby Ceilândia to 46.6C. Officials say planting in Sol Nascente cannot begin until narrow pavements and missing stormwater drainage are fixed, and have not given a timeline. Residents are meanwhile planting trees themselves, as climate change worsens heat-related health risks in neighbourhoods with far less green space than wealthier central districts.
