Recent floods in Belo Horizonte and other cities in Minas Gerais have alarmed residents. Videos showing the force of the torrents dragging cars and toppling structures shocked the entire country. This state of emergency was not confined to Minas Gerais. Much of the Southeast faced heavy rains, causing widespread disruption. In Espírito Santo, for instance, more than 5,000 people were forced to leave their homes, while São Paulo was placed on high alert for flooding. Meanwhile, in Rio de Janeiro, an algae bloom in water sources led to the opposite extreme: a water crisis triggered by the poor quality of the water reaching people's taps.
These events at the beginning of the year reveal how ill-prepared Brazil's major cities are to deal with extreme water-related weather events. Brazil needs new infrastructure, both to adapt its cities to heavy rainfall and to ensure its water supply system operates more efficiently.
