Soil Erosion Control Services
Soil Erosion has been a major issue in the past and will become an even greater issue in the future as population growth continues to expand and land resources are more intensively used, often to a point of destruction. Increased soil erosion means loss of land, reduced soil fertility, greater rainfall runoff, lower groundwater recharge, more sediment flows in river, higher contaminants in diminishing water supplies, lowered quality of drinking water, increased flooding, and diminished economic benefits and increased hardships to both rural and urban populations especially in developing countries, but also increasingly in developed countries too.
If applied correctly the Vetiver System could be an important tool to reduce erosion (by up to 90%), reduce and conserve rainfall runoff (by as much as 70%), improve ground water recharge, remove pollutants from water, reduce the risk of flooding, and improve economic benefits to communities.
Vetiver grass has been used (sometimes unknowingly) for these purposes for centuries in south India. In the last century the grass was taken around the world for use as an aromatic plant (root producing oil of vetiver); in some places such as Fiji, South Africa, and the West Indies it was grown as a hedge for soil conservation purposes. Since 1987 the use of vetiver for the latter purpose (grown as a narrow hedgerow across the slope of the land that slows down rainfall runoff velocity and filters out soil particles) has expanded significantly across the tropical and semi tropical countries of the world. Research and field results are well documented and can be found in the web site archives.
