“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 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…
