The long-term investment scenarios (LTIS) are an economic assessment showing what future flood and coastal erosion risk management (FCERM) could look like over the next 50 years in England. LTIS sets out the total national level of investment if we invest in all the places where the benefits are greater than the costs. This is called the optimum level of investment for FCERM.
This study takes into account:
- climate change
- how development on flood plains is managed
- future costs and benefits of managing flooding and coastal erosion
LTIS is evidence which government and others will use to consider future policy and investment choices. It is a set of national scenarios which describe possible ‘What if …?’ futures, but does not predict which of these futures will happen.
The Environment Agency produced LTIS 2014 and LTIS 2019.
In addition to LTIS 2019 there is a LTIS 2019 Technical Summary which contains the technical detail of the new analysis. Contact the Environment Agency for a copy of the LTIS 2019 Technical Summary.
