The Vetiver Network International (TVNI) promotes the Vetiver System (VS), a concept integrating simple scientific principals of hydrology, soil mechanics, and similar natural processes to manage soil and water on a landscape scale. The concept excels best when implemented using clones of a remarkable domesticated plant – vetiver (Chrysopogon zizanioides), a non fertile, noninvasive Indian clump grass cultivated for centuries for essential oil. Vetiver is central to a wide range of applications, generally installed as narrow linear barriers (hedgerows): its roots hold soil in place and dense ground-level stems restrain sediment flows. Unlike “hard” engineering approaches that weaken over time, VS grows stronger. It is a renewal of a traditional approach that has been validated scientifically, and expanded and promoted by TVNI. The VS provides significant economic, environmental and social benefits.

VS is now used in most tropical and semi-tropical countries, north to Italy and south to Chile. Based on research and demonstrations through TVNI “partners,” including research institutions, development agencies, NGO's and the private sector, VS has expanded from a technology primarily for farm soil and water conservation to include major applications for:

  • slope stabilization of public infrastructure (e.g., roads, railways, canals, rivers, construction);
  • prevention and treatment of contaminated domestic and industrial waste water;
  • reclamation of toxic mine-tailings and polluted industrial land;
  • disaster mitigation (e.g., stabilizing potential landslide sites, dikes and levees, dampening wind scour, and area protection against flooding);
  • soil improvement, wetland and marginal land restoration, and crop pest control;
  • renewable natural fibre for handicraft production, mulch, and thatch, etc.
  • bio-fuels

The Vetiver Network International (TVNI) promotes the worldwide use of the Vetiver System (VS) for a sustainable environment particularly in relation to land and water. The Network is a true network of individuals, groups, communities, entrepreneurs, and social organizations working together. The 'networking' part is all voluntary - no managers and no remuneration! We believe that it is one of the most effective non profit environmental organizations in the world and is impacting greatly on all levels of society.
