The Fens Need a New Water Settlement

A new set of reports from the Fens2100+ partnership delivers a clear warning: one of Britain’s most economically important landscapes is entering a period of rising risk, and the current approach to flood and water management is no longer enough.

That matters far beyond the Fens themselves. This is not just a story about drainage channels and flood banks. It is about food security, infrastructure, climate resilience, and the future growth of the East of England.

The Fens are home to more than 600,000 people, produce around a third of England’s vegetables, support 80,000 food industry jobs, and underpin nationally significant transport, energy, and industrial assets. But their productivity depends on an intricate water management system that keeps an extraordinarily vulnerable landscape functioning.

Why the current model is under strain

The reports underline just how exposed the Fens are: 87% of the landscape lies below mean spring tide level, and the system drains water from an area equivalent to 12% of England. This is infrastructure of national consequence, not just local importance. If it fails, the effects would ripple through supply chains, agriculture, communities and growth corridors linked to places such as Cambridge, Peterborough and Lincoln.

The challenge is growing. Ageing assets, heavier rainfall, stronger storms, rising sea levels, and increasing pressure from industry and communities are all putting the system under strain. The reports argue that climate change is not simply increasing risk; it is increasing the likelihood of cascading failures across an interconnected landscape.

Flood resilience is now a growth issue

What the reports suggest, though do not emphasise strongly enough, is that this is also a growth and water security issue. The future of the Fens is tied to the future of Greater Cambridge and the wider eastern region, where housing growth, population change, and innovation-led industry are already running up against environmental limits.

If water is not managed more intelligently, one of the UK’s most dynamic regional economies will hit hard physical constraints. The East increasingly faces a paradox: flooding in winter, water scarcity in summer. That exposes the limits of a system designed mainly to move excess winter water out to sea as quickly as possible.

The next phase must be different. More water will need to be retained, stored and reused, not simply drained away. That makes farmland reservoirs and wider landscape-scale water storage strategically important. They could capture winter surplus, support agricultural resilience, reduce pressure on aquifers and public supply, and help meet the needs of a growing population and economy.

From flood defence to water strategy

That is why the publication of the Baseline Summary Report, and the accompanying Case for Change matters. For the first time, the partnership says, there is a shared body of evidence on flood risk, asset performance and future pressures across the Fens. The Case for Change is explicit: it is an “unequivocal call to action” for a transformed approach to flood, coastal and water management.

The wider lesson is simple. Britain often thinks about growth in terms of visible projects: new homes, roads, railways, labs and energy schemes. But all of them depend on quieter systems of environmental management that make development possible in the first place. In the Fens, resilience is not an optional extra. It is a precondition of growth.

A warning — and a choice

The encouraging part is that the Fens2100+ partnership already exists to take this forward, with a Partnership Action Plan intended to combine short-term risk reduction with longer-term transformation.

The challenge is no longer just to maintain ageing defences or respond to each extreme event as it comes. It is to plan decades ahead, and to treat water as a strategic regional asset.

The Fens have always depended on engineering, investment, and collective action. The question now is whether policymakers are prepared to show the same seriousness as the generations who built the system the region still relies on.

These reports are not just a technical update. They are a warning — and an invitation to act.

About Fens 2100+

The Fens 2100+ Partnership is a collaborative initiative focused on creating a long-term, adaptive strategy to manage flood risk and water infrastructure across the Fens in Cambridgeshire, Norfolk and Lincolnshire. It brings together major organisations, including the Environment Agency, National Farmers Union (NFU), Internal Drainage Boards (IDBs), local authorities and water companies, to move from reactive repairs to a coordinated, proactive investment plan that protects the region's 600,000 residents and its vital agricultural land.
