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…
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…
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…
“Use geofabrics only when risk demands it — vetiver does the heavy lifting.” “Why pay 5 times more for geofabrics when vetiver does the real work?” “Vetiver isn’t vegetation — it’s bio‑engineering that stops slope failure.” Across the world’s highways,…
Liyu Xu, China Vetiver Network Coordinator, and his team from The National Institute of Soils (Nanjing), as well as many others, notably Xia Hanping (South China Institute of Botany), Lu Zhong-Xian (Institute of Plant Protection and Microbiology, Zhejiang Academy of…
The Microbial Engine Behind Vetiver’s Exceptional Performance . Across the tropics, vetiver grass has earned its reputation as one of the world’s most resilient biological tools for soil and water conservation. Its deep, fibrous roots anchor slopes, its dense hedges…
The Five Non‑Negotiables for Successful Vetiver System Establishment Effective vetiver installations don’t happen by chance. They require disciplined quality management with trained supervision to ensure every step—from cultivar selection to long‑term maintenance—meets Vetiver Grass Technology (VGT) design and application standards. When these…
The Vetiver Network International is pleased to present this new technical reference and guide: Standard Specification for Slope Stabilization Using Vetiver Grass. Authored by Dr. Mohammad Shariful Islam, a distinguished researcher and practitioner in the field of bioengineering, Dr. Islam’s…
From Scarred Mines to Blueberry Fields: A Story of Restoration from South China. In Baisha Town, Yingde City, the scars of illegal rare earth mining once defined the landscape. Jagged rocks and barren soil stretched across Mendong Village’s Fourth Pond,…
A testimonial from Alois Kennerknecht : The Vetiver System – a multipurpose plant in an urban community in Peru A few months ago TVNI launched a “Vetiver Testimonial Campaign” with an open call, asking you to share your stories and…
