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

NEW VETIVER PROGRAM FOR VIETNAM CENTRAL HIGHLANDS. NEW. The Vetiver Network International and the Chaipattana Foundation of Thailand are supporting the Vietnam Vetiver Network to develop a program to tackle the very bad soil erosion impacting farming communities in the highlands of Central Vietnam. The erosion and reduced soil moisture in negatively impacting farm production, particularly coffee, and is reducing water quality downstream in these highland catchments. The Vietnam Vetiver Network Coordinator, Mr. Van Man, and his program manager Ms. Nguyen Quyen are responsible for the program that was initiated on September 1 2015. They will work with a broard spectrum of agencies and users in Central Vietnam and will provide technical ltraining, plant supply and planning support for communities. TVNI is contributing US$20,000 and the Chaipattana Foundation has provided training support. In the past field trials at many sites in Vietnam have shown rhe effectiveness of VS for soil and water conservation and the positive impact on cassava and maize production. This work was never followed up until now. This program is worthy of additional support, and those interested might wish to contact Ms. Quyen.

Paul Truong, TVNI's Technical Director has updated information relating to the tolerance of vetiver to cold. His slide presentation - COLD TOLERANCE OF
- should be of interest to users who live in areas of hot summers and cold winters - especially in desert areas where winter night time temperatures are very low, but have high winter day time temperatures that reduce the possibility of freezing and killing the vetiver crown- we have to thank Matthew Huffine who lives in the high desert (Mohave) of California for this information. The presentation shows that Vetiver can survive very cold winter, but dies when the crown is frozen in the ground. In very cold, frosted or under snow cover the outside plants of the thick sward protect the interior part, which remains green and actively treating effluent. Under extremely cold and dry conditions, its shoots turn brown but new growth resumes from underground buds.

VETIVER SYSTEM NEEDS TO BE USED MORE WIDELY FOR STABILIZING INFRASTRUCTURE. Since 2000 the Vietnamese provincial governments have been testing and using the Vetiver Ssytem, at large scale, for highway (Ho Chi Minh Highway) -- and for Sea Dyke Protection in the Mekong Delta - These are a very important applications and show the impact of vetiver over 8-15 years of use. When the Vietnamese under take trials, they don't mess around with a few meters, instead they think kilometers! I can see VS application for highway and sea dike protection in many countries, but specifically in south and East Asia (China, Philippines, Indonesia. Thailand, Malaysia, Indonesia, Bangladesh and India). VS protection is long lasting and a very low cost (as much as 90% over conventional practices). The Vietnamese experience is FACT not FICTION and is applicable most places in the tropics. Why is it not being used widely? Many answers - the most important being: lack of knowledge, "too good, too cheap" syndrome (in other words PROFITS), and entrenched traditional habits or ignorance by those responsible - and in the latter I include many of the international and bilateral agencies! Please CORRECT me if I am wrong. Thank you Vietnam for showing the way.

VETIVER AND HEALTH - Improving quality of life in Haiti. Low cost and affordable sanitation. - The Vetiver Latrine.
"Those of those who are not familiar with the vetiver latrine. About one third of the global population does not have adequate access to a simple toilet. Logically it is the poorest of the poor that does not have this basic necessity and because they cannot afford them. The idea is to reduce the cost of a latrine by using vetiver as a construction material instead of bricks and cement. The design is a simple slab with vetiver planted around. The roots of the vetiver will stabilized the pit and the blades will act as a privacy screen. Using this technology we have been able to reduce the cost of a latrine from about $500 to about $25. Considering that most Haitians make less than $1.25 a day that makes sanitation affordable. If you are interested please check out
Progress and update: We finished another 247 latrines in April 2013 giving a total of 362 vetiver latrines. I did a survey of about 30% of the household of the batch that was completed in Sept 2012. After 2.5 years of use: (a) the latrines are self cleaning, 100% of the latrines were clean; (b) 0% of the latrines were mis-used (this is a common problem when NGO build latrines that are better than the homes they become storage depots and not latrines) (c) 100% of the households were satisfied with the latrine (d) none of the latrine pits collapsed; (e) people were very happy with the privacy screen; (f) of those who originally built a non-vetiver privacy screen 80% did not have one 2.5 years later. They said it was too much work maintaining a privacy screen and that the vetiver did a fine enough job; (g) when i visited the village in Nov 2014 all the latrines had only vetiver as a privacy screen.
There were no morbidity records before the project so it is difficult to quantify the public health benefit of the project. What we can say is that when there was a cholera outbreak in the area the village was not effected (Sanitation usually affects the spread of cholera not the initial infection). Anecdotally number of child deaths due to diarrhea has been reduced (we used to have one death every 2-3 months and for now people can't remember a child death from diarrhea for 15 months and counting)
We are looking into making the latrine more potable so that it can be produced in a centralized location and transported to remote sites"

VETIVER SYSTEM AND DROUGHT - How Vetiver saved a farmers herd of cattle in Venezuela. Climate change is resulting in severe droughts in some parts of the world.  The Vetiver System if applied and managed as a forage crop could provide communities and farmers greater resilience and protection.  Analysis of vetiver leaf shows that at a young stage its nutritional value is as good as the popular tropical grasses such as Rhodes, Napier, Star, Kikuyu and others. The key question is how to manage vetiver in order to  produce a quality forage.  Small farmers in Gundalpet, south India, know - they cut their vetiver hedges every three weeks - great forage! We need to apply an appropriate management approach, probably following controlled strip grazing or rotational grazing practices, for those farmers who could use vetiver as a forage crop at large scale. Here follows an interesting and related story from Raphael Luque of Venezuela titled "Vetiver Saved My Herd". . read on

VETIVER INSTALLATION GUIDE.

It is an excellent guide particularly for soil conservation applications. Recommended reading.

VETIVER SYSTEM TECHNOLOGY FOR INFRASTRUCTURE STABILIZATION. Paul Truong, TVNI's Technical Director has been visiting Argentina and Brazil, and has found an expanding interest in the Vetiver System for infrastructure stabilization. There are many companies in Latin America using VS for this purpose and following Paul's visit and presentations he has given we can expect more companies taking up the technology. You can find a pdf of his excellent presentation here.

CHINA - Railway EmbankmenChina railway embank pict Stabilization using Vetiver System. Liyu Xu, who started the China Vetiver Network in 1996, has produced a short description and images 14 years after the Xinchang railway Company planted 120,000 vetiver slips to stabilize a very difficult railway embankment using a sand fill. The vetiver was effective within 2 months of planting. The vetiver is still there and native plants have naturally colonized the embankment. Very poor farmers from the Dabie Mountains provided the original planting material, and since then farmers have cut the grass on the embankment for other uses, and have as a result prChina rail picovided the required "maintenance". China Railways has accepted the technology and promotes its use where appropriate. Everyone has benefited. What more does one need?!! See more on China Railways. NEW

VETIVER SYSTEM - A SOLUTION FOR URBAN WASTE WATER TREATMENT IN THE TROPICS?: In most cities, towns, and villages in developing countries there is no connection to a public sewage/waste water treatment.  Where there is a connection the effluent is often discharged without treatment to near by rivers. Where there is no sewage system some properties may have septic tanks, and the majority of these leak and miss function.  The result is that water tables, water bodies, and the local environment are polluted with consequential increases in foul smelling air, undrinkable water, and increased water borne diseases.  One such an example, described in a World Bank report on Indonesia describes the city of Palembang, South Sumatra, with a population of over a million having no direct sewage connections, and 70% of the households having septic tanks, of which 30% miss function.
Correcting this situation with conventional costly technologies for Palembang, and tens of thousands of other urban centers in the tropics will be prohibitive and will take decades. It is essential to start installing low cost, flexible, and sustainable remedies, that might not be perfect, but are able to reduce the problems significantly.
The Vetiver Phytoremedial Technology (VPT) as developed by Paul Truong is one such solution. Read more ......

John Greenfield provides a timely reminder that it is easy to lose focus on the essentials of improving crop production. He has prepared a note that underscores that lack of focus. "There is only one way to make rainfed subsistence farmers capable of producing food and cash crops on a sustainable basis, and that is by controlling runoff, no matter how little or how much, but by controlling runoff using dense vetiver hedges planted across the slope, as seen below. This is all it takes.
A simple vetiver hedge planted across the slope, as shown here, is anchored in to the ground by its massive 3+ m vertical root system. This is all the rainfed farmer needs to control runoff, slow it down, spread it out and prevent the loss of soil and nutrients, at the same time store essential soil moisture under rainfed conditions, for sustainable crop production. This non-invasive hedge of vetiver grass once established will last for decades without any special maintenance

Vetiver Phytoremediation Technology (VPT) -- Paul Truong is TVNI's Technical Director and a world authority on the use of vetiver grass technology for the treatment ofcontaminated land and water. We refer to this type of application as Vetiver Phytoremediation Technology (VPT) . He has recently prepared a useful photo essay 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.

If you have problems with dealing with waste water and sewage effluent on your property you may be able to use the Vetiver System to eradicate it. This model by Paul and Nicholas Truong shows you how, and the number of plants that you will need.

Treating Industrial waste water with Vetiver -- 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.

Vetiver System Overview plant 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:

  • slope stabilization of public infrastructure (e.g., roads, railways, canals, rivers, construction);
  • prevention and treatment of contaminated domestic and industrial waste water;
  • reclamation of toxic mine-tailings and polluted industrial land;
  • disaster mitigation (e.g., stabilizing potential landslide sites, dikes and levees, dampening wind scour, and area protection against flooding);
  • soil improvement, wetland and marginal land restoration, and crop pest control;
  • renewable natural fibre for handicraft production, mulch, and thatch, etc.
  • bio-fuels

All these applications impact positively on sustaining the environment and natural resources, while improving human welfare. For more details about the plant, its propagation and how to plant it go to this link g/the_plant.htm


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. x 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. c 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. x 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. x 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. x 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. x 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.

Vetiver System in Iran. Salman Shooshtarian of Iran has informed TVNI about ongoing work with VS in his country (see).  He and Ali Tehranifar have translated the Vetiver Grass Manual by Truong et al into Persian and there work has now been published in by Iranian Agricultural Science Publications: The Iranian Association for the Promotion of Vetiver has been established as an NGO - see their interesting presentation and the latest work on canal banks and rivers The visual demonstration and the quality of the vetiver plants and their growth clearly demonstrates the application of VS in semi arid and arid areas and is particularly applicable to Mediterranean and Middle East countries. Another VS application of great potential in these areas is for the treatment of waste water in its various forms on either small or large scale.
