The monsoon has not fully arrived yet, but India is already preparing for what it brings every year: swollen rivers, landslides, collapsing slopes, waterlogged cities and disappearing coastlines.

But the rain does not create disaster alone. The land’s ability to absorb, hold and slow water matters just as much.

And, that ability comes from roots.

Not all plants are equal in this. Researchers say, native plants, species that evolved with local rainfall patterns, are some of the strongest natural defences against monsoon damage. 

Across India’s different terrains, these plants hold soil, reduce runoff, slow erosion and act as living infrastructure.

And their role has already been tested.

Western Ghats: Vetiver, lemongrass, bamboo and wild turmeric

The Western Ghats are among India’s most landslide-prone zones during monsoon.

Districts like Wayanad, Kodagu and Idukki repeatedly face slope failures because of steep terrain and intense rainfall.

During the 2018 Kerala floods, several slopes that had been stripped for plantations or roadworks collapsed. But areas with vetiver grass planted along contours saw less topsoil loss.

Vetiver’s roots grow 3 to 4 metres deep, making it one of the strongest slope binders in the world.

Alongside it, lemongrass helps hold loose topsoil, bamboo........
