Soil erosion in the Western Ghats Region (WGR) increased by 94 per cent between 1990 to 2020, a trend that is "detrimental" in an area known to be a biodiversity hotspot, a study by the Indian Institute of Technology (IIT) Bombay has said.

Tamil Nadu fared the worst with the highest soil loss rate of 121 per cent from 1990 to 2020, the study said.
