Preventing Erosion
What’s the Problem?
- Accelerated erosion from poor farming practices accounts for 1.1 billion tons of carbon emissions annually.
- All of the world’s topsoil could be gone in 60 years.
How Can Building Healthy Soil Help?
- Agroforestry systems that prevent or reduce erosion on slopes include plantation polycultures, homegardens and multistrata systems, alley cropping and contour hedgerows, and silvopasture.
- One study found that multistory tree gardens actually had less erosion than a natural rain forest!
