India faces the following types of degradation of lands -->
i) Water logged degraded lands
ii) Saline/Alkaline degraded lands
iii) Wind degraded lands.
iv) Mined degraded lands

It has been reported that 40 tonnes per hectare of top soil is eroded annually.This is common phenomenon on the Western side of the country due to wind erosion.

Answer 2

More than a quarter of the total geographic area (TGA)-96.4 million hectares (mha) or 29.32%-in India is undergoing degradation as per decadal information compiled for the the period 2011-13, posing a major challenge to the country's commitment to the UN of achieving a land degradation neutral status by 2030.

The most significant process of degradation is water erosion (loss of soil cover mainly due to rainfall and surface runoff water) at 10.98%, followed by vegetation degradation (mainly as deforestation) at 8.91% and wind erosion (denotes the spread of sand by various processes) at 5.55%.
