What looks like a simple ditch in a pasture is actually a powerful tool for protecting the land.
No one knows this better than Laurence Manchee of Keela Permaculture Farm, who recently detailed why he dug swales in his field as a way to prevent water runoff and topsoil erosion.
In a YouTube video, Manchee explained that swales are essentially ditches along the natural contour lines of land that catch water and spread it around the field naturally. These ditches capture and slow rainwater runoff, allowing it to soak into the ground instead of flooding a given area. Swales can also spread the water uphill and store the water in the ground.
"The water sinks into the ground, getting more water in the landscape," Manchee said in the video. "Before these, the water would just rush down the middle of the field, taking the topsoil with it, and the water would disappear into the stream and off the land."
Swales are low-cost, environmentally minded solutions that help farmers adapt to extreme weather events — like heavier rain and hotter, drier conditions — driven by human-caused climate shifts.
As Manchee explained, swales help to recharge groundwater, reduce erosion, and limit pollution flowing into rivers and oceans. Swales can also help reduce the risk of drought by storing more water locally. Plus, they help support the healthy, lush habitats essential for biodiversity.
Swales are a textbook example of permaculture, a sustainable design approach that focuses on working with nature rather than against it.
By following permaculture principles, we can design farms, gardens, and entire communities that function more like natural ecosystems. And this approach makes it possible to produce food and use resources more responsibly — in ways that are sustainable and beneficial for both people and the planet.
The video didn't just showcase an impressive example of permaculture; it also gained praise from viewers happy to see responsible land stewardship in action.
"There are still good and smart people out there," one viewer wrote.
