How could the findings on natural flood management affect the Environment Agency?
The Environment Agency may shift focus to integrating nature-based flood defenses The research demonstrated that combining natural flood management measures, such as ponds, wooden dams, and tree planting, can reduce peak river flows by as much as 62 per cent during storms across five Devon river catchments. This evidence provides scientific backing for the concept that nature-based solutions can complement conventional engineered defenses. As the primary regulator for flood risk, the Environment Agency may need to adjust its guidance and investment priorities to incorporate these proven, nature-based approaches into its overall flood management strategy.

How it reaches Environment Agency
-
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 the government agency responsible for environmental policy, DEFRA commissioned the study to test new ways of helping communities become more resilient to flooding. The findings show that working with nature can complement engineered defenses, suggesting that the Environment Agency must consider integrating these proven methods into its regulatory and operational framework.

Why it matters
For the Environment Agency, the findings represent a significant scientific validation of nature-based solutions in flood defense. While the Agency already manages flood risk, the data provides a strong, quantifiable case for prioritizing and investing in measures that work with the landscape, rather than solely relying on traditional, engineered defenses like flood walls.
This shift is particularly relevant given the expectation that climate change will increase the frequency and intensity of extreme weather events. The research highlights that a combination of relatively small, localized measures can collectively make a real difference, offering a new layer of protection that complements existing infrastructure.
