River Restoration Reduces Flood Risk by 27% While Boosting Drought Resilience
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Restoring river catchments with natural flood management techniques can reduce flood risks by 27.3% and boost river flows during dry spells by 27.1%, creating resilient water systems that benefit both communities and ecosystems.
📈 One key stat: Natural flood management at Smithills Estate has reduced peak storm flows by 27.3% and increased water flow during dry periods by 27.1%, demonstrating how landscape restoration creates dual protection against floods and droughts.
💬 One key quote: “Even after a year of exceptional rain and flooding, the soils and ecosystems that should be buffering us against drought are depleted. This recent spell of dry weather has exposed just how fragile the system has become.”
1️⃣ The big picture: The UK faces critical water challenges as spring 2025 becomes the driest since 1893, with rainfall 43% below average and multiple regions entering drought status. Decades of drainage, overgrazing, and peatland degradation have transformed uplands into fast-draining systems where rainwater rushes through landscapes instead of being absorbed. This creates a dangerous cycle of rapid flooding followed by severe drought. However, landscape restoration projects like Smithills Estate near Bolton demonstrate how natural flood management techniques can effectively address both issues. By restoring bogs, planting trees, and improving soil structure, these initiatives help landscapes retain water longer, reducing both flood risks and drought impacts.
2️⃣ Why is this good news: Restored landscapes act as natural infrastructure that regulates water flow, providing protection against both floods and droughts simultaneously. At Smithills Estate, restored peatlands function like sponges, absorbing rainfall and releasing it gradually during dry periods. The natural flood management techniques implemented there have measurably reduced peak storm flows while boosting river levels during dry spells. These approaches benefit wildlife by creating valuable habitats and connect communities with their natural environments through volunteer opportunities in tree planting and monitoring. The solutions can be implemented relatively quickly compared to traditional infrastructure and deliver multiple benefits beyond water management, including carbon storage, biodiversity enhancement, and recreational spaces.
3️⃣ What’s next: The UK must scale up nature-based solutions as essential infrastructure to avoid routine water restrictions and secure future water supplies. This requires collaborative efforts between landowners, water companies, local authorities, regulators, and communities. Expanding landscape restoration needs to be matched with changes in land management practices to rejuvenate natural processes that regulate water flow.
