The cylinder irrigation method for reafforesting denuded dune soils in Mauretania was developed under a cooperation project between Mauretania, the FAO and the UNDP. It is recommended for use on dune soils where rainfall is insufficient to ensure continuity with the residual moisture, and hence eliminates the barrier of a dry horizon preventing newly-planted trees from reaching the deeper, moist layers. The quantity or water necessary varies according to the depth of the existing moisture. Trees planted seven years ago using the cylinder method are still alive without having been watered.
