Using vetiver grass to trap sediment and re-establish indigenous forest – Aneityum Island, Vanuatu (New Zealand). A brief retrospective 6 years after NZAID funding ceased.
The project combines Vetiver grass and coco-fiber on dike in Botolan, Zambales. (1) 2.3 kilometers length, an average of 6 meters slope surface run; (2) Vetiver rows planted at 10 plants/meter in between coconets; (3) 25 workers finished the project in 21 working days; (4) 22,000 sq.m. of nets were used; (5) 766 pcs. of logs laid out and connected.
Soil nailing is commonly implemented to strengthen the weak structure of the soil on the very steep slopes. However, soil nailing does not provide protection against surface erosion on these slopes. Application of Vetiver bioengineering is a perfect compliment for controlling the surface erosion problem of soil nailing. The slides demonstrate this complementary effect in Medellin, Colombia, and Vietnam.
Hoa Nhon Commune has recently been recognized by the DaNang People’s Committee as a new rural area. It is focusing this year on promoting its production activities in order to boost the development of the locality. The Healthyfarm is the project sponsored by ADB (Asian Development Bank) and Danang People’s Committee. However, since the location of next to a river, only within 01 year, 03 meter of land has been […]
In the city of Can Tho, river erosion seriously happened due to tide and waves caused by transportation. So planting Vetiver on the banks of rivers and canals would help reduce erosion and landslides. A failure in protecting river banks Vetiver has been successfully combined with stone embankments, stabilizing river banks along waterways to the Phong Nha-Ke Bang in Quang Binh, contributing to preserving the environment and landscape to attract […]
The bridge is on the way to the center of Tay Giang district, Quang Nam province, which was a very high embankment with rocky soil and being ready to be eroded. To protect this infrastructure, Tay Giang District planted Vetiver grass on the contour with a strict caring procedure at the beginning. After 01 month of implementation, the grass grew well and guaranteed requirements of specifications. One month after the […]
At Laguna Hue resort, investors set strict requirements in terms of ecology and landscape. The combination of vetiver and concrete system once again proved its effection in protecting slopes at Laguna Hue resort. A comparison between slopes with and without vetiver The model of combination between Vetiver and concrete system Instead of the concrete, Vetiver was used in combination with the “soil nail” to reinforce the slopes. Because the […]
The project of stabilizing tali along Ho Chi Minh Highway (3,000 kilometers in total) spreading from Thanh Hoa to Kontum province is probably the most typical engineering method applied for road slope stabilization in Vietnam. Erosion before planting vetiver After 08 months of plantation After only a few rains, the newly opened slopes were eroded and washed away severely (top) […]
From March to July, 2016; Vietnam Vetiver Network, SBTV Construction and Advanced Technology Company designed and implemented Vetiver plantation for 7,433 sq.m of the Bac Me Hydropower Dam in a mountainous Northern Region of Vietnam. Cement grids are used as a solution to prevent erosion of the dam wall. But these grids are often washed away during heavy rain periods and typhoons. So Vetiver was planted in the hope of […]
Phu Yen is a Vietnamese province frequently facing many natural disasters, especially big tides and waves of the Central Coast. Climate change consequences are increasingly severe and Phu Yen province is the most affected area. Although there were policies proposed to minimize the damage of tides and waves, they have been pending, which caused difficulties to daily life, production and settling of locals. As such, in the near future, there […]
