<strong>After</strong> <strong>the</strong> <strong>flood</strong> - <strong>preparing</strong><br />
<strong>Copenhagen</strong> <strong>for</strong> <strong>climate</strong> <strong>change</strong>
<strong>Copenhagen</strong> Climate Adaptation Plan<br />
• The plan was approved by <strong>the</strong><br />
City Council <strong>the</strong> 25. august 2011<br />
• Identification of threats<br />
• Determines an overall strategy<br />
• Pointing to <strong>the</strong> overall solutions<br />
• Must be accompanied by<br />
concrete action, such as<br />
Cloudburst Plan and construction<br />
activities<br />
• www.kk.dk/english
Main challenges<br />
Rain<br />
Flooding from <strong>the</strong> sea
Risk assessment - rain water and<br />
sea level <strong>flood</strong>ing<br />
• Estimated costs and <strong>the</strong><br />
probability of damage show<br />
that rain water is <strong>the</strong> most<br />
immediate threat<br />
• But in 30 years time <strong>the</strong> risk<br />
of <strong>flood</strong>ing due to rising sea<br />
levels will be greater (and<br />
<strong>the</strong> damage higher)<br />
‣ Long decision making<br />
process - complicated<br />
financing<br />
‣ Consequences <strong>for</strong> urban<br />
development<br />
‣ There<strong>for</strong>e we must start<br />
planning now
Risk map
And <strong>the</strong>n we<br />
thought we<br />
had 30 years<br />
to implement<br />
<strong>the</strong> plan…….
Cloud burst <strong>Copenhagen</strong> 2. juli 2011
July 2011 - damages<br />
• More 150 mm rain within 2<br />
hours<br />
• Close to 1 billion euros in<br />
insurance claims<br />
• Damage to critical<br />
infrastructure<br />
• Hospitals minutes from<br />
evacuation<br />
• Emegency services<br />
threatened
Reality check
Cloudburst plan<br />
Hvordan får vi vandet og CO2 ud af KBH?
Decision of safety level
Methods and priorities
Prioritizations….<br />
1. Areas with high risk<br />
2. Projects that are easy to<br />
implement<br />
3. Synergy with o<strong>the</strong>r<br />
projects - road and<br />
implementation of water<br />
frame directive<br />
4. Still aiming <strong>for</strong> a green<br />
and blue city
A green and blue city -<br />
adapted to a future <strong>climate</strong> = more quality of life<br />
• Adaptation is not just a<br />
negative measure<br />
• We can increase <strong>the</strong><br />
recreational area and create<br />
more quality of life <strong>for</strong><br />
copenhageners<br />
• We can help make<br />
copenhageners more<br />
healthy<br />
• We can create synergy with<br />
o<strong>the</strong>r planning<br />
• We can increase<br />
biodiversity.
Handling more water and developing a recreative waterfront<br />
Main problem: a polluted harbour<br />
and a combined sewage system.<br />
An unattractive harbourfront<br />
A plan <strong>for</strong> reducing sewage<br />
owerflow was made and<br />
accepted by <strong>the</strong> city<br />
administration in 1992<br />
Developing a park along <strong>the</strong><br />
harbour front
Tools<br />
• construction of rain- and sewage<br />
water reservoirs<br />
• Reduction of rainwater in <strong>the</strong><br />
sewage<br />
• Cleaning of run-off water from<br />
<strong>the</strong> roads
Harbour baths - a huge improvement of <strong>the</strong> quality of life
Methods to ensure <strong>the</strong> city from <strong>flood</strong>ing
Skt Annæ Plads
A <strong>climate</strong>proof neighbourhood
Adaptation is a new precondition in urban<br />
development<br />
• Will influence <strong>the</strong> way we<br />
utilise and plan urban spaces<br />
• Will influence <strong>the</strong> use and<br />
development of recreative<br />
areas in <strong>the</strong> city<br />
• In <strong>the</strong> future we have to make<br />
sure that we can manage and<br />
control water when we<br />
develop <strong>the</strong> city, and we will<br />
actively use water as a<br />
resource to improve <strong>the</strong><br />
urban life
Challenges<br />
• The scale - we are remodelling <strong>the</strong><br />
rain water management i<br />
<strong>Copenhagen</strong><br />
• Environmental issues (EUwaterframe<br />
directive) - balancing<br />
between safety and environment<br />
• Urban development<br />
• Demographics - <strong>Copenhagen</strong> is a<br />
growing city
