Jim Hall’s work on coastal flood risk wins Lloyd’s Science of Risk Prize
A paper co-authored by the Director of the Environmental Change Institute, Professor Jim Hall, has been awarded the Lloyd’s Science of Risk Prize in the Climate Change category at a ceremony held at Lloyds of London on 29 November 2012.
The research, led by Professor Richard Dawson at Newcastle University, revealed that in some cases, allowing natural cliff erosion, rather than maintaining physical defenses could reduce the impact of flooding in neighbouring low-lying land.
Populations in coastal areas face considerable threats from sea level rise and increases in the frequency and intensity of storms associated with climate change. Urbanisation and expanding economic activity in these areas only add to the scale of risk.
This award-winning study, entitled ‘Integrated analysis of risks of coastal flooding and cliff erosion under scenarios of long term change’ and published in the journal Climatic Change, used an integrated assessment methodology to explore the trade-offs between flooding and coastal erosion risks on the Norfolk coast.
Professor Hall and colleagues analysed the complex interactions between climatic and socio-economic change and coastal management policy, and for the first time quantified in economic terms, their impact on both flood risk and coastal erosion.
“By understanding some of the interconnected processes we start to appreciate that flood protection is not just about building the biggest dyke possible,” said Professor Richard Dawson, speaking to the Lloyd’s Science of Risk team. “There are other ways of working more subtly with nature and natural processes rather than trying to tackle nature head on and fighting it with a wall.”
