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…
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…
Mapping the Vetiver System Worldwide: A New Country-by-Country Evidence Table TVNI has compiled a comprehensive country-by-country evidence table documenting the global reach of the Vetiver System. The table currently covers 120 countries and territories — each assessed across six evidence categories:…
Not because it isn’t raining. Because we have spent seventy years building systems designed to move rainfall off the land as fast as possible — graded terraces, drainage channels, sealed surfaces — and into rivers that carry it to the…
“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 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…
The Vetiver System in 2025 The most outstanding aspect of the Vetiver System in 2025 were the people of the VS global community. WhatsApp groups in India and Latin America, the monthly Latin American Conversatorios, and numerous active Facebook groups…
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,…
