Extreme rain, overwhelmed drains: Why Bangkok flooded and what could have been avoided
Bangkok experienced severe flooding following extreme rainfall, affecting hundreds of thousands of residents and exposing weaknesses in urban drainage and water management. Experts suggest that despite previous infrastructure upgrades, the city remains vulnerable to climate-driven disasters.
Why it matters
This underscores the urgent need for cities to improve climate resilience and urban planning to mitigate the impact of increasingly frequent extreme weather events.
Thailand has strengthened its flood defences since the catastrophic 2011 disaster, but recent extreme rainfall has exposed persistent weaknesses in drainage, urban planning and water management, say experts.
