More about Fens 2100+ and FAQs

The Fens landscape is largely below sea level – it’s at the forefront of climate change. Water levels must be managed 24 hours a day, 365 days of the year. 

Living and working in the Fens is only possible because of around 17,000 flood risk management and water level management assets, such as pumping stations and defences. Without these, the area would revert to marshy fens and lowlands, liable to frequent flooding from the sea and rivers. 

Added to this are several pressures including agricultural demands, population growth, areas of socio-economic deprivation, water availability for people and farming, increased flood risk and sea level rise. Many of the flood risk assets were built in the 1960s primarily to manage the land for food production and will need significant investment to maintain them in the medium and long term. 

Over the next 100 years, an additional investment of  at least £4.5bn will be needed to manage flood risk in the Fens – that’s based on today’s cost and not accounting for climate change. Applying current flood risk management funding rules to that £4.5bn would mean about 50% of it would be funded, the rest isn’t.

Fens 2100+ will make sure we support how we deliver flood risk management now, but we’re also looking to the medium and long-term to try to determine what's the right investment we need to make across this landscape that achieves the outcomes that we all want – for people, the environment, and more widely.

This is also about making sure we are putting the investment in the right places, not limiting future choices, and helping this landscape adapt to climate change into the future – rather than just doing what we’ve always done.
