Majority of Indians live in rural areas. Our population is constantly rising but the job opportunities are not rising at same rate. So, a very large number of people depend on agriculture for getting employed.
The number i.e. the supply exceeds the demand. Even if some labourers are removed from agriculture the overall agricultural productivity will not be affected. Hence, rural areas experience disguised unemployment.
Moreover, the labourers in agriculture sector gets work only during sowing and harvesting season and so they remain unemployed rest of the time.
Also, monsoon is irregular and we lack proper irrigational facilities.
As a result, India also faces seasonal unemployment.
