Vetiver grass offers climate-smart solution for PNG’s Future

Papua New Guinea is turning to a powerful nature-based solution to combat climate change, with Vetiver grass gaining attention as a sustainable tool for environmental protection and land restoration.

Environmental advocate and founder of Vetiver Systems Ltd, Robinson Vanoh, says the deep-rooted Vetiver grass can play a major role in both climate change mitigation and adaptation strategies for the country. He has been promoting the technology in PNG for over 20 years.

“Vetiver has the potential to reduce soil erosion, control landslides, stabilize roadways, restore degraded land, and boost water absorption during heavy rainfall,” said Vanoh in an interview.

He explained that the grass, native to India and Southeast Asia, was first introduced to PNG in the 1980s in Kimbe, West New Britain, by an Indian national.

One of the latest successful pilot sites is the Kokoda Trail Motel, where the grass is being used to stabilize the landscape, protect the environment, and promote eco- tourism.

Vanoh said he has distributed over one million Vetiver slips in key centers like Port Moresby, Goroka, and Lae.

He urged the PNG Government to recognize Vetiver technology as a key component in the National Adaptation Plan. 

“This is a proven bioengineering method that’s low-cost, effective, and community-driven,” he said.

Schools, youth groups, and community leaders are also being encouraged to join the Vetiver movement to learn how simple, nature-based solutions can deliver long-term climate resilience and sustainability for PNG.
