Vetiver Networking and Expanding Application in Tanzania

Goodluck Estomih, of Arusha, Tanzania, has played a critical role in the more recent promotion of the Vetiver System in Tanzania. He writes … “My greetings to you from Mara region in the Lake Victoria zone of Tanzania. … Not known to many, we established in June 2017 a What’s app group called VENIT (Vetiver Network in Tanzania), after an intensive and comprehensive training by Elise Pinners (TVNI Director) and Jane Wagesa (Kenya Vetiver Network Coordinator).… Read the rest “Vetiver Networking and Expanding Application in Tanzania”

The Vetiver Education & Empowerment Project (VEEP) Model. 

For those who understand and have witnessed the significant benefits and impact of Vetiver System (VS) applications, are often perplexed that the technology is still unknown by many potential users despite global promotion efforts. Degradation of soil and water is accelerating, due to population growth, misuse and mismanagement of resources, and climate change. Many communities, particularly rural communities in poor countries know the problems but lack the means to mitigate them. The challenge of climate change calls for new approaches in delivering information and in training and empowering communities in need.

Coal Flyash Dump Successfully Stabilized with Vetiver Grass

When not stabilized and protected, fly ash dumps, associated with coal fired power generation plants, are serious health hazards due to heavy metals (Zn, Pb, Cu, Ni, Cd, and As) in the fly ash dust and associated dumpsite leachates. These toxic chemicals impact surrounding people, animals, land and groundwater. Phytoremedial mitigation using vetiver grass can be very effective, primarily through phytostabilization of the fly ash, with phytoextraction of toxic metals as a secondary benefit.  Vetiver when grown in fly ash: has a dense mass of ash binding roots; is tolerant to the heavy metals (that when extracted remain mainly in the roots — the leaves can be fed safely to livestock or used for other purposes); and shows no significant sign of plant damage thus assuring long term survival.  … Read the rest “Coal Flyash Dump Successfully Stabilized with Vetiver Grass”

China – Vetiver Research and Development

China – Vetiver Research and Development. Recently Liyu Xu, China Vetiver Network Coordinator, sent me the digital text (in English) of a book published in 2003 relating to the title of this post. It contains useful information and data from 1988 to 2003 – a period when there was a lot of vetiver activity following the introduction of the Vetiver System to the World Bank funded Red Soils Project located in Jiangxi and Fujian Province in 1988.… Read the rest “China – Vetiver Research and Development”


MAP YOUR VETIVER LOCATION COMPETION. This competition closed on March 31. The leaders Vetiver TT (Trinidad and Tobago), Tho Ngo (Vietnam), and Vetiver GT. Ingeneria-Viva- (Guatemala) are listed in the attached image from the iNaturalist site. We audited the first three (excluding Grimshaw – ineligible to compete) and found all to have a few deficiencies. They have been asked to update and correct. These will be then checked again and the winners announced by the end of April   XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX   MARCH 31, 2022 DEADLINE: VETIVER PLANTING LOCATION MAPPING – CASH PRIZE COMPETITION. … Read the rest “MAP YOUR VETIVER LOCATION COMPETION”

Vetiver Roots – The Hidden Half.

  This new book by Dr. Paul Truong provides a wealth of information on the function and unique role of the roots of vetiver grass that allow for a wide range of environmental mitigation. Paul Truong, TVNI’s Technical Director, has been undertaking research and development of Vetiver System Technology (VST). He was fortunate to be located in Queensland, Australia, allowing him to research and apply a wide range of VST applications, under many different climatic and ecological conditions.… Read the rest “Vetiver Roots – The Hidden Half.”


The tropical island watershed conservation “Ridge to Reef” concept is a popular strategy for reducing soil erosion and sediment/pollutant movement from the upper watersheds to populated coastal areas and in-shore waters. Ridge to Reef programs could be accelerated and be more effective if Vetiver Grass Technology (VGT) was applied more widely and through community initiative.

New Website and “News and Opinion” page

Welcome to TVNI’s new website designed by Green Global of Da Nang, Vietnam. The team, led by Hoang Nhat Truong, has done a terrific job for which we are truly grateful. We now have a fully secure website that has visual appeal and easy navigation, containing the mass of information that has been collected over 35 years. The website will continue to perform its primary function as a critical knowledge center for the Vetiver System. The website is divided into four sections: Network Services – including the important Document Center.… Read the rest “New Website and “News and Opinion” page”

Transitioning Tropical Nations’ Economies towards Sustainable Survival

The Vetiver Grass Technology (VGT) contribution Climate instability and pollution have created considerable environmental, economic, and financial difficulties for tropical countries to the point that some are facing a very uncertain future, unless their economies begin transitioning to towards Sustainable Survival (SS). SS is defined as the coordinated and simultaneous management of water, air, soil, biodiversity, CO2 emissions/absorption and all related resources, to maximise the resultant economic and social welfare in an equitable and harmonious manner without compromising the sustainability of vital ecosystems whilst they are all in a constant state of flux.… Read the rest “Transitioning Tropical Nations’ Economies towards Sustainable Survival”

Nature Based Infrastructure (NBI), the role for Vetiver Grass Technology

A recent report, ”How Can Investment in Nature Close the Infrastructure Gap?”, dated August  2021, from the Nature-Based Infrastructure Global Resource Center made the case for nature based solutions for the development and maintenance of infrastructure. Nature based infrastructure NBI is on average 50% cheaper and 28% better value for money. If used extensively it could save $248 billion out of an annual estimated $4.29 trillion cost annually for infrastructure in addition an estimated $189 billion could come from additional benefits.… Read the rest “Nature Based Infrastructure (NBI), the role for Vetiver Grass Technology”
