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.

Lake Naivasha, an important Great Rift Valley Lake in Kenya is in trouble. It is polluted by silt, agrochemicals, and urban effluent. Unless a solution is found the Lake will die. All the land and water problems within its large catchment area show up in the lake: waste water from Naivasha town, agro chemicals from nearby intensive export crop businesses, and soil erosion throughout its 2,500 sq km watershed attributed to small scale and very intensive unprotected farming. Community and technical solutions are required to avert disaster. The Vetiver System can provide part of the solution in all the problems areas. For more see

VETIVER SYSTEM - EROSION CONTROL - FEED BACK

I have dug out of our archives five papers of interest relating to Vetiver Systems erosion control programs in Ethiopia, India, Indonesia, and Thailand. They are of importance because of the upcoming workshop in Ethiopia and the general need for VS as a tool in dealing with the current world food crisis. An underling feature of all the reports is that adequate technical advice, farmer training, proper application and prolonged effort is required to assure long term success. The reports are: Ethiopia 1; Ethiopia 2; India; Indonesia; and Thailand.

Vetiver System for Soil Erosion Control in Ethiopia. A slide show put together by Alemu Mekonnen in 2000 gives quite a good idea of the soil erosion and soil loss that Ethiopian farmers are faced with, and how the Vetiver System can help mitigate the problems. Since 2000 VS applications have extended to many other parts of the country. A paper describing this work provides a good background this slide show.

Don Miller of New Zealand has been working in Vanuatu (South Pacific island) for some years and demonstrates in this slide show how vetiver hedgerows can be used as an essentail part of reforesting badly eroding landscapes to prevent sediment reaching the sea and destroying coastal coral reefs and fisheries. Don's work can be replicated throughout most island ecologiies where eroding sedimnt flows are effecting coastal habitats in the tropics

This interesting study by Julius H. Mangisoni covering 450 farmers indicates farmer preference for the Vetiver System. The Net Present Value Model has demonstrated that vetiver bunds are the most profitable and effective methods of combating soil erosion. The effectiveness of the vetiver bunds lies in the fact that they combine two technologies (bare contour bunds and vetiver grass) and the vetiver grass has an excellent rooting system.

Evaluation of Nutrient Trapping by Vetiver Grass: In Soil Eroded Area of Anno Agro Industry Farm, Gobu Sayo district, East Welega Zone, Oromia Regional State, Ethiopia [Paperback] Abdisa Gesesse Wayuma (Author)

This book available at Amazon.com showed that Vetiver Grass has significant impacts on soil conservation and nutrient trapping.It improves most of the soil physicochemical properties and soil productivity due to the fact that vetiver plants form hedges or a living porous barrier, which slows and spreads run¬off water and traps sediment. And the author recommends that vetiver grass system is an effective soil conservation system in trapping nutrients at low cost and the use of vetiver grass is recommended as an affordable and sustainable soil management practice to improve soil fertility.
