The world is in the grips of a flood crisis. As millions in Pakistan remain affected by flooding that has killed more than 1,500 people, Typhoon Noru has lashed the Philippines and Vietnam. Hurricane Ian, which left a trail of destruction in Cuba, has brought devastating floods to Florida. “We’re continuing to see deadly rainfall, catastrophic storm surges, roads and homes flooded. We’re seeing millions of people without power and thousands hunkered down in schools and community centres,” said US President Joe Biden.
“They’re wondering what’s going to be left — what’s going to be left when they get to go home … or even if they have a home to go to. Some of the folks have been through this before, but that doesn’t make it any easier.“
But while extreme weather is becoming a new reality in the wake of intensifying climate change, death and destruction doesn’t have to be. Increasingly, flood adaptation and mitigation solutions are being trialled and developed by governments, private industry and the research community.
Some solutions relate to infrastructure — such as reservoirs and drainage systems — while others involve a rethink of where and how societies are developed, moving communities out of flood-prone areas.
Alongside changing the look and location of communities, living in a flood-resilient world requires a shift in policy and culture. Governments must be adaptable and proactive, willing and able to mobilise resources ahead of floods to assist in preparing, evacuation and clean-up.
REALITY CHECK
The 2022 Pakistan floods have cost the country an estimated US$10 billion, almost four percent of the country’s GDP, according to planning minister Asad Umar. Between 1998 and 2017, two billion people worldwide were affected by floods. 23 percent of the world’s population is vulnerable to flood risk.
BIG IDEAS
Quotes attributable to Linda Speight, University of Oxford:
"The climate is changing. Extreme weather is occurring more frequently and there is an urgent need to increase flood resilience. To live successfully in a changing climate, all aspects of society need to be ready to adapt when warnings are issued."
"Communicating extreme events is difficult. An individual’s response to flood warnings is often influenced by their previous experience. Without having seen a river in full flood, it is very difficult to comprehend the destructive power of water or appreciate the urgency of preparation."
PERSPECTIVES
Flood warnings that don't break the banks Linda Speight, University of Oxford Affordable and accurate, flood warnings have advanced to be a great tool to prevent disaster. But that’s proving to be only half the battle.
Building a disaster-ready culture in Indonesia Wahyu Wilopo, Universitas Gadjah Mada Indonesia had almost 10,000 floods last decade, and flood incidents keep rising. To turn the tide, new cultural and infrastructural solutions may be needed.
Disaster proofing healthcare key to flood resilience Sotiris Vardoulakis, Australian National University, Veronica Matthews and Ross Bailie, University of Sydney Building back smarter from floods is about more than infrastructure. As Australia is finding out, improvements to healthcare are key to the solution.
Jakarta’s floods are devastating — they don’t have to be Dwita Sutjiningsih, Universitas Indonesia Jakarta’s severe flooding is happening more often and with more intensity. A new approach might hold the key to moving forward.
