Stone bunds in Burkina Faso helped reduce erosion on 250,000 acres

In Burkina Faso in only 15 years, farmers using zaï in Burkina Faso have made tens of thousands of badly degraded acres productive and contour stone bunds, reducing erosion, have been built on a at least 250,000 acres with the help of development organizations. With the addition of manure is added, the results are stunning – with cereal yield increasing sevenfold or more without fertilizer.
