Will Europe sink?

DW: Speaking at the Energy Security Conference in Frankfurt this month, you said we tend to focus on the impact humans have on the environment, but that we should also examine the impact our environment is having on us. What did you mean?

Cleo Paskal: We are in a world that is changing, not just for climate change reasons but because of population increases, depletions in groundwater, populations moving into increasingly vulnerable areas. What happened in New Orleans during Hurricane Katrina was the result of building on floodplains. It was a city in a hurricane zone that was hit by a hurricane. It was not a surprise. It created an enormous social, political and economic disaster, from which the region still hasn't recovered.

So, environmental change, and its effect on us, is being seen increasingly and in an accelerating way. This is going to change the way economies can sustain themselves, the way countries interact with each other and the way power is projected across the board.

You have also said that European infrastructure and our policies are created without a sense of the world we are going to be facing in 20, 30 or 50 years. You've mentioned flooding as an example. You said it made sense 300 years ago to build in low areas near water, but that isn’t a good plan today. Could you explain?

Unfortunately, Germany just suffered some very tragic flooding. If you look at the towns, most of them are quite old, which means that they haven't been consistently flooded, otherwise they would have moved. Also, they were designed for a very specific time and a very specific place and a very specific population size - much smaller populations, more mobile and different climatic conditions. Very static conditions.

In most of Europe - and definitely Germany - our infrastructure and locations were chosen 500, 700, even a thousand years ago, that's how old the towns are. A lot has changed in that time but we haven't changed the locations which we put our infrastructure in. As a result, we are increasingly vulnerable as the variability comes. And it's not just the location but the population size. These towns were designed for 10,000 people, not 100,000 people. So, an already vulnerable location gets stressed more and more and that makes it even more vulnerable to disruption.

So, you want people to start thinking about moving to safer spaces or building new cities rather than shoring up the ones that we have?

The insurance sector is starting to discuss this because they're the ones that have been picking up the bill. You are already starting to see places in the UK, for example, where houses just can't get insurance any more. If you can't get insurance, you can't sell your house.

They're not getting insurance because they're vulnerable to catastrophes?

Because they flooded. In fact, in the UK they built houses on floodplains. The sellers said, 'we guarantee you can get insurance'. So homeowners got the insurance and when they flooded, they got the payout. But then the insurer said once is enough and we're not going to pay out again. Now homeowners are stuck with houses on a floodplain that they can't get insurance for. This isn't one or two cases – this is potentially tens of thousands of cases and increasingly more across Europe as the floodplains change and increase.

What conversation would you like policymakers to have?

I'd like them to have real discussions about risk, where risk isn't discounted, distorted or diverted into other factors. If a place is too dangerous to build in, don't back it with federal insurance. Let the market say this is too dangerous to build in and just pull out.

This is a problem across the western world. This is why the US national flood insurance program is consistently bankrupt: because the market has said it's too dangerous. But the government has said but we want the tax revenue from the beachfront properties. So they push the risk of the flooding off onto the global or the state-wide taxpayer by providing federal flood insurance. By discounting, distorting or diverting risk into other areas, we're getting a very unreal sense of the vulnerabilities in our systems.

How does Europe perceive this?

Europe thinks this is mostly a developing world problem but it's not. Actually the countries with the oldest, most static, least adapted infrastructure are the old Western countries like the ones in Europe. This infrastructure is hundreds of years old, it's for a different time. Also, the population expects a very high level of responsibility from the government, whereas in places like India people have generators at home because they know not to rely on the government. If their house floods out they have friends they can stay with, the social networks are extremely strong. So if Europe thinks that it's in a better position than the emerging world, it really needs to re-think.
