Rio Grande do Sul Overhauls Civil Defense After Record 2024 Floods

In May‑June 2024, unprecedented floods struck Rio Grande do Sul, inundating 478 of the state's 497 municipalities and affecting about 160,000 people in Porto Alegre, where 46 neighbourhoods were flooded. The disaster highlighted serious gaps in the region’s flood‑prevention infrastructure.

In response, the state government is restructuring its Civil Defense. All municipalities have now submitted contingency plans, with more than 80% rated as moderate to good. The reform includes creating a dedicated civil‑defense secretariat, adding 102 specialist positions (geologists, engineers, meteorologists, etc.), acquiring four new weather radars, and planning a State Integrated Risk and Disaster Management Center for next year. These measures aim to shift the culture toward proactive risk mitigation and improve coordination between state and local authorities.

The overhaul is supported by national civil‑defense policy alignment and international partnerships such as ICLEI, which is helping conduct participatory workshops to refine the state’s resilience strategy.
