Bridging the Adoption Gap: TVNI’s 2026 Engineering Standards for Slope Stabilization

For three decades, Vetiver Grass Technology (VGT) has demonstrated extraordinary technical performance in stabilizing engineered slopes—yet struggled with institutional adoption. Hong Kong documented ten years of zero slope failures, then rejected vetiver. Hawaii faced $70 million in flood damage and…

Become a Farmer-Researcher: Six Vetiver System Models to Transform Your Farm

An Invitation to Farmers and Other Vetiver Users Choose Your Path, Document Your Journey, Share Your Knowledge What if the greatest agricultural research wasn’t happening in laboratories, but on your farm? What if farmers like you—working the land, observing the…

Vetiver’s phytoremedial mechanism, and how it might mitigate water pollution in tropical countries with India as an example

Vetiver Phytoremediation – The  Mechanisms Vetiver grass (Chrysopogon zizanioides) removes agricultural and waste water (sewage) pollutants through four integrated biological mechanisms operating simultaneously. (1) The foundation is its massive vertical root system reaching 3-4 meters depth, creating enormous surface area…

NEWSLETTER (NL2026-04) The 9-Degree Solution: What Vietnamese Farmers Discovered (And Science Had Already Proven}

Welcome to an extraordinary month in the Vetiver world. From Vietnamese farmers making remarkable discoveries to Brazilian associations taking flight, from Ethiopian insights finally being understood to engineering breakthroughs that challenge conventional thinking—this month reveals vetiver’s true power not just…

The Hidden Benefits of Vetiver

When Farmers Discover What Science Had Already Proven The Vietnamese Discovery The Vietnam Vetiver Farmers Group (facebook.com/groups/vetiver4vn) has become the world’s most innovative vetiver community through careful field observation and documentation. Their farmers noticed something remarkable: crops planted close to…

Newsletter (NL2026-02) — A belated February newsletter & Global Water Bankruptcy, Patricia Tello Reátegui, Potential Funding Opportunities for VS Practitioners, VS Academic Visibility, Slope steepness & rooting, and others….

Our February Newsletter is coming out quite late for technical reasons: we have just migrated the TVNI website from its long time host, CSS Communications (of Bellingham, Washington) to a new host and so were “down” during the transfer.  As…

New Experimental Evidence: Vetiver Nearly Eliminates Runoff — What This Means for Micro Catchment Restoration

For years, practitioners across the Vetiver Network have known — from field experience, hydrological logic, and scattered academic studies — that vetiver hedgerows dramatically increase infiltration and reduce destructive runoff. Yet one of the persistent barriers to institutional uptake has…
