Europe-wide flood losses to 'increase four fold' by 2050

RATE THIS! +42
Posted in Science on 3rd Mar, 2014 11:48 PM by AlexMuller

Flood damage losses across Europe are expected to increase four fold by 2050. The scientists believe that the continent's annual flood costs may be 23.5bn euros by the middle of the century. Two-thirds of the projected increase in flood damage will be caused by human development, not climate change. The study has been published in the journal Nature Climate Change.

 
One of the big problems for European flood disaster research has been that countries tend to do their risk assessments on their own, using different models and methodologies compared with their neighbours.
 
"This is not an accurate way of working," said lead author Brenden Jongman from VU University in Amsterdam.
 
"We show that if you have very high flood risk in the UK there is also a very high risk in northern France, the Netherlands and some parts of Germany."
 
Rather than looking at individual flood risks, the team decided to look at maximum water discharges in over 1,000 European river sub-basins, or parts of catchments.They found that different rivers often reach dangerous levels at the same time, threatening large regions.
 
"If you don't take into account these spatial co-relations then you highly underestimate the risk - there is a much higher risk than we actually think so far," said Mr Jongman.

The observation that flooding risks in Europe are linked should encourage countries to work closer together and share advances in the combating foods

Another important point made in this article is that socio-economic growth is very important factor - as they state " More people are living in flood-prone areas, [and] the income per capita is increasing in the dangerous areas around Europe" - We need measures to moderate this

In any case, this research clearly shows that there is an opportunity in acting - I agree that we should start doing things in a way that avoids false sense of protection. We need to act for real! Reply

Climate change should also be taken into account - this link is however usually quite difficult to prove beyond doubt Reply

Other coastal flood protections, not just levees, should be considered. They range from restoring wetlands and beaches, which in some cases are a more affordable alternative, to building more costly large barriers that can be opened and closed. Reply

Many options should be considered: levees, wetlands, sea walls, and mechanical barriers as well as softer adaptation options like stronger coastal permitting and improved flood evacuation maps ...... Reply

It is likely that losses from floods will be even more significant in future and investing in defences should be taken very seriously. The amount of damages likely to be caused is far more than the costs of prevention

Just look at predictions: They say for Europe "the average annual losses are expected to increase by a factor of four between now and 2050." This should lead to actions now! Reply
