How Vetiver Retrofits Turn 7% Yield Losses Into 200%+ Gains—While Suppressing Pests Farmers Never Expected (the photos in this article are all from Ethiopia and show vetiver planted in the mid 1990s and the early 2000s) The transformation of Ethiopia’s…
Comprehensive Assessment of Staple Grains, High-Value Perennials, and Vegetable Crops Under Rising Soil Temperatures—and the Vetiver Solution The Crisis Beneath Our Feet While the world fixates on rising air temperatures, bare degraded soil now reaches 43-50°C during peak sun versus…
Our February Newsletter is coming out quite late for technical reasons: we have just migrated the TVNI website from its long time host, CSS Communications (of Bellingham, Washington) to a new host and so were “down” during the transfer. As…
“Use geofabrics only when risk demands it — vetiver does the heavy lifting.” “Why pay 5 times more for geofabrics when vetiver does the real work?” “Vetiver isn’t vegetation — it’s bio‑engineering that stops slope failure.” Across the world’s highways,…
Liyu Xu, China Vetiver Network Coordinator, and his team from The National Institute of Soils (Nanjing), as well as many others, notably Xia Hanping (South China Institute of Botany), Lu Zhong-Xian (Institute of Plant Protection and Microbiology, Zhejiang Academy of…
Across the tropics, farmers are fighting a battle on two fronts: declining soil health and rising pest pressure. For decades, the response has been predictable—more chemicals, deeper tillage, and higher costs. But a quiet revolution is spreading across Africa, Asia,…
For nearly 40 years, the Vetiver Grass Technology (VGT) has been recognized worldwide for its unmatched performance in soil conservation, slope stabilization, hydrological protection, and watershed rehabilitation. But one of its most powerful biological functions—its ability to act as a…
For decades, root‑knot nematodes (Meloidogyne spp.) have quietly undermined tropical agriculture, reducing yields in bananas, chilli peppers, tomatoes, cassava, sweet potato, and dozens of other crops. Their damage is often misdiagnosed as drought stress or nutrient deficiency, leaving farmers with…
The Microbial Engine Behind Vetiver’s Exceptional Performance . Across the tropics, vetiver grass has earned its reputation as one of the world’s most resilient biological tools for soil and water conservation. Its deep, fibrous roots anchor slopes, its dense hedges…
