Retrofit thousands of kilometers of constructed bunds, terraces, fanya juus BY planting one row of vetiver along the upslope foot (toe) of bunds or on the outer edge of terraces and these structures will start showing the benefits of vetiver hedgerows. The cost is minimal the benefits are huge.
Vetiver’s deep roots (3+ meters) stabilize soil structures, preventing erosion and structural failure. The dense hedgerows filter sediment, slow runoff, and enhance water infiltration. Unlike aging earthworks that deteriorate, vetiver strengthens over time, reduces maintenance costs, and creates living barriers that adapt to terrain while providing long-term erosion control, land productivity and many other benefits not obvious to the casual user.
