Vetiver TT EES – Roots of sustainability in a tropical climate

Factsheet Block Body

Vetiver TT, a for-profit social company with public and private sector clients, has introduced vetiver grass to Trinidad and Tobago, demonstrating that it can be used as a simple and cost effective environmental and conservation solution to stabilise slopes, control erosion, conserve soil and water and rehabilitate contaminated water and land in tropical climates.



Factsheet Block Body

A twin island country situated off the northern edge of the South American mainland, the Republic of Trinidad and Tobago has long thrived on fossil fuels, leading it to embrace large-scale construction and commercial activities whilst discouraging the development of a sustainable economy. Despite having ideal conditions for year-round farming, for example, Trinidad and Tobago imports more than 90% of its food.

Volatile oil prices are forcing Trinidad and Tobago to diversify, and its citizens are waking up to the environmental fallout of industrial development and consumerism. There are still pristine places in the country, but environmental catastrophes such as decimated hillsides, quarries and landfills, which leak leachate into water supplies and waste into rivers and seas, serve as stark reminders of the environmental works and transitions needing to be undergone.

Entrepreneurial Approach and Innovation

Factsheet Block Body

Vetiver TT EES Ltd has developed a “soft engineering” technique which uses vetiver grass to address diverse environmental challenges in tropical climates. When implemented according to the Vetiver System (VS), hedgerows slow down runoff, and capture and recharge groundwater, also stabilising slopes, protecting against erosion, conserving soil and water, and cleaning contaminated land and water through phytoremediation. Vetiver TT EES Ltd serves clients including homeowners facing soil movement issues, commercial construction companies, as well as public infrastructure and community development projects.

Vetiver grass (Chrysopogon zizanioides), the key component of VS, offers a green and cost-effective way to rehabilitate the degraded hillsides of Trinidad and Tobago’s Northern Range, where forest fires rage every two to three years in the dry season and subsequent rains wash away topsoil and often cause flooding downstream. Because it is certified sterile and non-invasive by the USDA, the grass poses no risk when introduced to new areas, yet costs as little as 15% to 20% of “hard engineering” alternatives.
