OTHER USES OF VETIVER GRASS
The Vetiver Network International (TVNI) is a global nonprofit dedicated to promoting the Vetiver System and its core nature based Vetiver Grass Technology (VGT)—Chrysopogon zizanioides—to restore degraded land, conserve water, protect infrastructure, and build climate resilience. Through a decentralized network of volunteers, practitioners, researchers, and community leaders in over 100 countries, TVNI empowers local solutions to global challenges.
We advance sustainable development by applying vetiver grass technology across diverse landscapes—from farms and flood-prone slopes to polluted sites and urban infrastructure—delivering practical benefits such as erosion control, soil regeneration, disaster risk reduction, and economic opportunity through handicrafts and biomass.
Founded in 1995 by Richard Grimshaw, TVNI builds on World Bank-supported research and a scientific foundation rooted in hydrology, soil mechanics, and plant ecology. Our open-source, volunteer-driven model fosters collaboration, innovation, and knowledge sharing—without central management or paid staff.
TVNI supports the achievement of key Sustainable Development Goals (SDGs), including Zero Hunger (SDG 2), Clean Water (SDG 6), Climate Action (SDG 13), and Life on Land (SDG 15), while offering accessible educational resources, field-tested guides, and community-driven success stories.
