|The Vetiver Network International (TVNI) promotes the worldwide use of the Vetiver System (VS) for a sustainable environment particularly in relation to land and water. The Network is a true network of individuals, groups, communities, entrepreneurs, and social organizations working together. The "networking" part is all voluntary - no managers and no remuneration! We believe that it is one of the most effective non profit environmental organizations in the world and is impacting greatly on all levels of society. The VS provides significant economic, environmental and social benefits. VS is now used in most tropical and semi-tropical countries, north to Italy and south to Chile. Based on research and demonstrations through TVNI “partners,” including research institutions, development agencies, NGO's and the private sector, VS has expanded from a technology primarily for farm soil and water conservation to include major applications for: ..... more|
Vetiver Phytoremediation Technology (VPT) NEW -- Paul Truong is TVNI's Technical Director and a world authority on the use of vetiver grass technology for the treatment of contaminated land and water. We refer to this type of application as Vetiver Phytoremediation Technology (VPT) . He has recently prepared a useful photo essay (left) on the use of VPT for waste water treatment, comparing the before and after impact of vetiver. There are also two water treatment programs one, in Singapore (using C.nemoralis instead of the more efficient C. zizanioides) that Paul helped design, and the other in Oman (using Ph ragmites sp) designed by BAUER Umwelt GmbH of Germany). Both have interesting design features, and both could use C. zizanioidies. This slide show can be downloaded as a pdf file.
COMPUTER MODEL FOR TREATMENT OF SMALL VOLUME WASTEWATER
Treating Industrial waste water with Vetiver - NEW - Here is a nice example from Paul Truong of how vetiver can be used for industrial or agricultural waste water treatment using floating pontoons (best design yet) and by planting on the banks of the lagoons. There is great potential to apply the Vetiver System for waste water treatment not only on industrial scale but also for smaller treatment needs for single households, small hospitals, hotels, schools, refugee camps, etc. using the alternative "wetland" vetiver application.

Biotechnology Environmental Solutions (Soluciones ambientales en biotecnología)using the Vetiver System. NEW Yorleny Cruz who is TVNI's Associate Director for Costa Rica and Central America as well as a senior partner of Vetiver Panama SA, has shared with us an excellent presentation (MB19) in Spanish (with some English). The presentation focuses on wet tropical bioengineering stabilization of roads, river and canal banks, gullies, drainage. and landslide works using the Vetiver System. It comprises some 127 slides (nearly all from this website archive) and should be very useful for introducing VS technology to new clients particularly those needing solutions to deal with the extreme rainfall events that are occurring more frequently because of climate change. She hopes that others will use the presentation in the promotion of VS. Yorleny and TVNI take the opportunity to recognize all those vetiver users who have contributed to this photographic presentation. NOTE: Sharing information on this website helps accelerate the use and awareness of this unique plant and technology. Sharing (contrary to what some people think) is good for us all, good for Planet Earth and good for our businesses however large or small.

|Pollution of Planet Earth’s Food Supply Source: NEW - Did you see the recent article in The Washington Post “Chinese official: Soil pollution hurts farming” claiming that at least 8 million acres of Chinese farm land will be closed to production due to contamination by heavy metals and other contaminants, including the over use of agricultural chemicals? This problem is not just confined to China. In India ground water is not only being depleted at an alarming rate, but it is also being polluted by overuse of agricultural chemicals and by toxic effluent from industry. “A recent Punjab state water department survey found that 1,166 of its nearly 7,000 projects were contaminated with heavy metals including arsenic, uranium and arsenic beyond permissible limits”. Additionally the overuse of nitrogenous fertilizer has in places seriously contaminated groundwater – the consequence - contaminated food and drinking water, and an increased incidences of cancer and other ailments. This problem also occurs in the USA. The Salinas Valley in California has serious nitrate contaminated groundwater due to years of fertilizer use for intensive agricultural cropping. Learn how the Vetiver Phytoremediation Technology can help remediate these problems ....|
|Vetiver Greetings for 2014 – What happened in 2013?
The worldwide Vetiver family had another good year in 2013. It was exciting to see expanding use of Vetiver System applications in most parts of the world, often from people and places that we rarely hear from.
The year’s highlight was The Second International Latin American Conference on the Vetiver System that was held in October in Medellin, Colombia, and very ably organized by Daniel Londono of the Colombian Vetiver Network. There was excellent attendance and some very interesting presentations from most of the region’s countries covering various applications. It was interesting to see how individuals, communities, private companies, schools, and Universities were all making their contribution to furthering this great technology. I was personally moved by the work of Alois Kennerknecht of Lima, Peru, who, using his own money, had virtually single handed introduced VS for beautification, soil conservation, and other purposes to some very poor inner city urban communities. In Madagascar, our current “Vetiver Champion”, Yoann Coppin, continues his excellent work with a number of cross sector applications that show what can be done when you put your mind to it! We thank the companies and individuals who contributed to the conference in kind and funds. Read more and download complete article .....

|Vetiver System Overview Learn More
The Vetiver Network International (TVNI) promotes the Vetiver System (VS), a concept integrating simple scientific principals of hydrology, soil mechanics, and similar natural processes to manage soil and water on a landscape scale. The concept excels best when implemented using clones of a remarkable domesticated plant – vetiver (Chrysopogon zizanioides), a non fertile, noninvasive Indian clump grass cultivated for centuries for essential oil. Vetiver is central to a wide range of applications, generally installed as narrow linear barriers (hedgerows): its roots hold soil in place and dense ground-level stems restrain sediment flows. Unlike “hard” engineering approaches that weaken over time, VS grows stronger. It is a renewal of a traditional approach that has been validated scientifically, and expanded and promoted by TVNI. The VS provides significant economic, environmental and social benefits. VS is now used in most tropical and semi-tropical countries, north to Italy and south to Chile. Based on research and demonstrations through TVNI “partners,” including research institutions, development agencies, NGO's and the private sector, VS has expanded from a technology primarily for farm soil and water conservation to include major applications for:
|Soil Erosion Control: The Vetiver System is the premier soil erosion method outside of temperate zones. Narrow hedgerows of Vetiver grass will spread out rainfall runoff across the slope, act as a filter to trap erosion sediment, create natural terraces and reduces the velocity of rainfall runoff. It has application for on farm soil and water conservation, rehabilitation of eroded lands, and prevention of erosion on sloping lands. Learn More|
|Agriculture Improvement: The Vetiver System has many agricultural uses for: soil and water conservation, soil moisture improvement, groundwater recharge, recycling soil nutrients, pest control, mulch, forage, clean up of agricultural contaminated waste water, protection of farm infrastructure (canals, drains, roads, and building sites. Learn More|
|Slope Protection: The combination of deep roots with tensile strength of 75 MPa that improve the shear strength of soil by as much as 40% makes Vetiver grass an ideal plant for stabilizing steep and unstable slopes. The Vetiver System when applied to such slopes significantly reduces the probability of land slippage and reduces the need for “hard solutions”. Applications include highway, railway, riverbanks, public utility right of ways, canal, dikes, and levee slopes. Learn More|
|Disaster Mitigation: The Vetiver System can be used to reduce potential disasters caused by extreme rainfall events. Stabilization of levees and sea dikes reduces the chance of breaching and subsequent devastating flooding. Steep slope protection by Vetiver grass reduces potential land slippage caused by high rainfall events. Learn More|
|Prevention and Treatment of Contaminated Water and Land: The Vetiver grass will tolerate high levels of nitrates, phosphates, heavy metals, and agricultural chemicals. The Vetiver System can be used for treating wastewater, rehabilitating mine tailings, stabilizing landfills and general rubbish dumps. The Vetiver System takes up the toxic materials and confines the contaminates to the effected area. Learn More|
|Community Quality of Life and Poverty Reduction: In most developing countries many of the Vetiver System applications can be applied at minimum cost to poor rural communities to enhance quality of life through protection of water supplies, improving soils and increasing farm benefits, cleaning up waste water and reduction of diseases, protection of rural infrastructure, and providing by-products for handicrafts, forage, mulch, thatch, medicines, and Vetiver plant material for sale to other users. Learn More|
|Landscaping: The Vetiver System can be applied for urban landscaping including beautification, slope stabilization, traffic dividers, demarcation of walkways, prevention of urban erosion etc. Learn More|
|Handicrafts: Vetiver grass provides a source of excellent material for handicrafts, particularly if the leaves are properly processed first. Sometimes, as in the case of Venezuela, a handicraft program for women and girls led to the Vetiver System being used for other applications. Thus adding to the quality of communities and community effort. Learn More|

|From Sally Holker - Women Weave of India - "I planted vetiver three monsoons ago on my eleven acres of land (Central India, on the banks of the Narbada River, near Maheshwar). The original idea was to arrest the erosion of my very unstable terrain, which slopes at a twenty degree angle from the north (top) down to the river (south) and was slowly washing the whole story away. That has completely reversed itself now. The vetiver has been a miracle and has multiplied many times over. Not only is the land stable, but also we have been able to use the leaf of these plants very effectively in a project close to my heart. For thirty years I have been committed to increasing rural employment for women in our area through handloom weaving. Most of the area weaves cotton and silk. We are now weaving vetiver leaf; making and selling beautiful table mats and runners."
From Debela Dinka - Sustainable Land Use Forum, Ethiopia. "According to our partner NGO in Illubabor, Ethio-Wetlands and Natural Resource Association (EWNRA), vetiver technology is more or less being used in 17 districts of 22 in Illubabor. It is estimated that about 17,000 households are using vetiver. It is expected that the remaining 5 districts will be involved. The major impacts of vetiver are: decreased rate of soil erosion; increased crop (maize sorghum, vegetables) yield due to soil and water conservation; reduced siltation of wetlands & streams; groundwater recharge which subsequently improved flow of springs, streams & wetlands; survival rate of tree & coffee seedlings reached more than 80%. Other uses of vetiver: mulching in coffee plantations; thatching of houses, stores & shades (vetiver grass gives long time service); mattress making (it repels home fleas & other insects); homestead hedgerows for beautification; making rope; income generation (farmers sell vetiver clumps for planting materials); and the green leaves of vetiver are cut and spread in & around homes during holidays & social gatherings such as wedding ceremonies."
From Tran Tan Van - Vietnam. "Vietnam, like most countries, suffers natural disasters and environmental degradation. The threat from future rising sea levels puts Vietnam in the top five most endangered nations. Yearly 1000 people die during storms; as a result of toxic pollution of waterways, yearly average property damage is $300,000,000. The government understands the need to mitigate these effects but has resorted to using piecemeal, conventional engineering works. These are very expensive, technically complicated and are not durable. TVNI’s introduction of VS into Vietnam 7 years ago was for Vietnam “a timely glass of fresh water to the thirsty desert traveller”. It has been tested, demonstrated and adopted by the government, the research community, the private sector and individuals. The speed of its adoption over large landscapes attests that it is indeed the solution to myriad problems. Vietnam represents one of the world’s most successful cases of VS use".
|USDA/NRCS endorses Vetiveria zizanioides (Sunshine cultivar) In a very useful and practical plant guide USDA/NRCS supports the use of Vetiver (Sunshine cultivar) for soil and water conservation, slope stabilization and phytoremediation. It also vindicates Vetiver as a non invasive plant:
"For approximately the past 15 years, no volunteer seedlings have been observed from conservation plantings of Sunshine in the Pacific Islands Area. Sunshine was evaluated for invasiveness by the Hawaii-Pacific Weed Risk Assessment and Pacific Island Ecosystems at Risk. It received a low risk score (-8) for the potential to become invasive." Note: Sunshine Vetiver has the same genotype (DNA tested) as the majority of cultivars of Vetiveria zizanioides used under the Vetiver System throughout the world.
