Ground water recharge 2. Wetland RestorationIn Ethiopia, under a similar climate as the Mau forest area, extensive areas of farm landhave been protected with Vetiver hedgerows (top left). These hedgerows, in some caseshalted erosion and runoff entirely, resulting in substantial crop yields due to improved soilmoisture, better soil fertility (the latter - reduced loss of fertilizer, and improved soil structure,organic matter, and nutrients though mulching with Vetiver. An unintended benefit was therestoration of adjacent wetlands (top right). Before VS was used this area was dry and usedfor football games. Now it has been restored by groundwater. You can see bodies of water.Wild life (migrating birds) have returned, and substantial forage sources are now available.Today the Ethiopian Wetland Society is a major promoter of the Vetiver System
Pollution ControlResearch and full scale applications ofVS for pollution control has beendemonstrated in Australia, China, andThailand. When correctly designed andapplied VS can be used to stabilize andprevent pollutant flows from landfills,sewage works, and from industrial andagricultural effluent discharge
