New evidence to plan for flood and coastal risks

The Environment Agency has published a new economic assessment to plan for flooding and coastal risk management during the next 50 years.

The study will use climate change, population and mapping data to identify potential scenarios and assess how funding should be allocated.

The Long-Term Investment Scenarios Report states that, without sustained investment, flood damage to properties and infrastructure in England will increase. The Agency estimates that an average investment of £1bn will be needed up to 2065.

A variety of measures are needed to ensure communities are resilient. This includes building and maintaining large-scale engineered defences, natural flood management techniques such as planting trees and slowing water flow, and flood resilience for homes.

During the next 50 years, the number of properties on the floodplain is estimated to double. Continuing to make the right decisions will be crucial to keep pace with population growth and climate change.

Julie Foley, the Environment Agency's director of flood strategy, said: “This report sets out the level of investment we need to consider over the next 50 years, alongside the action we need to take.

“The scenarios are a key evidence base to inform our Flood and Coastal Erosion Risk Management Strategy, due later this year, and will help government, businesses and the insurance industry plan for the future.“
