Why in news
Central Railway is adopting vetiver grass plantation as a bio-engineering solution to mitigate soil erosion and landslips in the Western Ghats.
Background
Central Railway plans to plant vetiver grass (Chrysopogon zizanioides) in Bhor Ghat and Thal Ghat. The grass is chosen for its dense root system which stabilizes soil and reduces surface runoff. A pilot plantation of 5,300 sq m has already been initiated.
Facts for Prelims
- EnvironmentVetiver Grass (Chrysopogon zizanioides) is used for soil stabilization and erosion control.
