How could the research on natural flood management affect government policy?
Natural flood management research may influence government resilience policy The research found that combining small natural flood management measures, such as ponds, wooden dams, and tree planting, can reduce peak river flows by up to 62 per cent during storms. Because the study was commissioned and funded by the Department for Environment, Food and Rural Affairs, the findings provide evidence that can inform national policy. The results suggest that working with nature can complement conventional engineered defenses, requiring the government to consider the right measures in the right places when planning flood risk management across the country.

How it reaches government
-
A University of Exeter team studied 662 storms across five Devon river catchments. The research found that natural flood management measures, such as small ponds, wooden dams, and tree planting, can reduce peak river flows by 30 to 62 percent during storms. The study, which included 26 log jams and 15 ponds, was funded by the Department for Environment, Food and Rural Affairs.
The full event1independent outlet -
As a government agency, the Department for Environment, Food and Rural Affairs uses the evidence from the study to guide national policy. The findings show that a combination of relatively small measures can add up to make a real difference, helping to hold water back and reduce the volume of water reaching properties downstream.

Why it matters
The findings are critical because climate change is expected to increase the frequency and intensity of some extreme weather events, making flood resilience a major national concern. The government must balance the need for conventional engineered defenses with the potential benefits of nature-based solutions to protect communities and infrastructure.
Defra, as a specialized agency mandated by the government, is already involved in coordinating resilience efforts. The research provides specific, localized evidence that supports the idea that a combination of small, nature-based measures can complement larger, traditional flood defenses, potentially shifting how national flood risk is assessed and managed.
What we don't know yet
- What level of national funding would be required to implement these natural flood management measures across various catchments?
- How will the government weigh the cost-effectiveness of nature-based solutions against traditional engineered defenses?
