Flood Defences: Enough After Storm Desmond?
5 Dec
Summary
- Over £600m invested in flood risk reduction since Storm Desmond.
- Climate change complicates assessing current flood protection levels.
- Experts debate if new defences are sufficient for future storms.
Since the catastrophic Storm Desmond flooded thousands of homes and businesses in 2015, more than £600 million has been invested in flood risk reduction across Cumbria and Lancashire. Despite this significant expenditure, experts express uncertainty about whether current defences are sufficient to protect against future extreme weather events.
The escalating impacts of climate change present a complex challenge, as the frequency and magnitude of storms are becoming unpredictable. While flood defences have been enhanced for nearly 4,000 properties in Cumbria and Lancashire, and £20 million invested in the Tyne Valley, scientists caution that a storm of Desmond's significance would still pose considerable problems.
Newer, nature-based flood management techniques are being explored, with £25 million spent on such methods over the past decade. However, hydrologists emphasize the urgent need to scale up these initiatives. Some experts also propose considering more drastic long-term solutions, including the managed relocation of communities from extremely vulnerable coastal areas, a difficult but potentially necessary step.
