Flooding in the Jardim Pantanal district, located in a floodplain area of the Tietê River, highlights the increasing threat of climate-related disasters in Brazil. In December 2024, the city of Pindamonhangaba experienced a deluge that left neighborhoods submerged and roads flooded. To combat these challenges, the city has invested in smart city technologies, deploying sensors to monitor environmental factors like water levels and temperatures.
Pindamonhangaba’s early warning system, powered by software developed by Brazilian startup iNeeds, has already saved lives by providing timely alerts. The city’s focus on climate resilience extends beyond flood prevention, with sensors now detecting wildfires and mosquito populations. These initiatives have been successful in part due to the recent implementation of 5G technology, allowing for real-time data transmission.
However, challenges remain in ensuring comprehensive coverage and connectivity for the sensor network, particularly in rural areas. Despite these hurdles, the collaboration between national systems like CEMADEN and local sensor networks in cities like Pindamonhangaba has proven to be effective in addressing climate threats. This collaborative approach has also found success in states like Paraná, where technological solutions are being prioritized for environmental disasters like landslides.
As extreme weather events become more frequent, the adoption of smart city technologies and proactive approaches to climate resilience have become essential for authorities at all levels in Brazil. While challenges persist, the long-term benefits of these investments in technology far outweigh the costs. The innovative approaches pioneered by Brazilian cities like Pindamonhangaba have the potential to serve as a model for other communities globally facing similar climate challenges, ultimately helping build resilience in an uncertain climate future.
