UK Environment Agency publishes new evidence to plan for flood and coastal risk up to 2065

March 4, 2019

 

 

 The Environment Agency has published a new economic assessment to aid planning for flooding and coastal risk management over the next 50 years. The long-term investment scenarios use new climate change, population and mapping data to set out potential future scenarios, assessing how funding could be best allocated to meet these challenges.

Digestible Bullet-points

  • Under a plausible extreme climate change scenario (IPCC A1FI), there are more places where new investment is not cost effective.
     

  • In the high climate change scenario and with current effective planning outcomes it’s possible to prevent risk from increasing. 
     

  • Conventional investment strategies suggest an overall cost benefit ratio of 5 to 1 i.e. for every £1 invested about £5 of property damage would be avoided.
     

  • With optimum investment and outcomes in this new study, that ratio increases 9 to 1.
     

  • Using strict economic criteria alone and not considering the social impacts, assets would be left to degrade. This would increase risk.
     

  • Using a potential new method to calculate the benefit cost ratio for a flood risk management scheme the impacts on mental health increase from 16:1 to 24:1.
     

  • Building and maintaining large-scale engineered defenses, using natural flood management techniques such as planting trees and slowing the flow of water, and property flood resilience for homes will be required.
     

  • Planning policy mitigation measures can reduce risk to properties on flood plains, for example, raised floor levels.
     

  • It is not just property at risk from flooding. Transport and utility networks are at risk (41%) requiring protection investment.

 

The Environment Agency is investing £2.6 billion in flood and coastal erosion risk management projects between 2015 and 2021, helping to protect 300,000 homes.
