The Vetiver Grass Technology or Vetiver System is a multipurpose green technology intervention used for both urban and rural infrastructure protection from soil erosion and earth movements. The technology relies on the good structural properties of the root system of Vetiver grass (deep long and straight roots) with a very high tensile strength i.e. 1/6 of mild steel, stronger than any other type of vegetation including trees. The grass exhibits non invasive properties, good adaptation to new environments, cost effective – properties that make it good for broad applications.

Based on past applications in soil control erosion projects on roads and farms, the technology has proved to be one of the good complimentary interventions to concrete based treatments for infrastructure protection
