Drought Monitoring :
During 1965 and 1966, major parts of India were under prolonged and
severe drought conditions due to deficient monsoon rainfall. On the
recommendations of the Planning commission, Drought Research Unit
started functioning at Pune in 1967 in the office of the Additional Director
