In News: Jharkhand and Uttar Pradesh are experiencing the worst monsoon season of the century.

  • Food and water scarcity are going to be the real issues in the country’s major rice producing states, with a potential to affect India’s kharif produce this year.
  • Between June 1 and August 12, the rainfall recorded over Jharkhand was 371.9mm against a normal of 627.6mm, a 41 per cent seasonal deficit. This is the lowest ever rainfall recorded over Jharkhand (June to August) since 1901, the IMD’s rainfall data stated.
  • For Uttar Pradesh, too, the picture is grim, as the state has recorded only 251.7mm of the seasonal average of 449.1mm till August 12.
  • UP is the most rain deficient Indian state this year and has remained so since the start of the monsoon season.

  • In a departure from the norm of overflowing Ganges and flooding, the 2022 monsoon has been anything but normal for Bihar. During the ongoing season, Bihar has recorded 376.5mm versus a normal of 602.6mm, a deficit of 38 per cent, till August 12.
  • Overall, the month of July was the driest over the East and Northeast India since 1903; it ended with a 45 per cent rain deficit.
  • Since the monsoon onset, Manipur, Tripura and West Bengal remain in the rainfall ‘deficient’ category.
  • Only Assam and Meghalaya, Sub-Himalayan West Bengal and Sikkim and Arunachal Pradesh in the east and northeast India regions have recorded normal rainfall this monsoon season.

So, what are the causes for rain deficit?

  • This season, only three low pressure systems developed in the Bay of Bengal, mostly off the coast of Odisha.
  • None of these systems impacted Jharkhand, Uttar Pradesh or Bihar.
  • Thus, one of the two rain-bearing causes remained out of favour for these states.

Monsoon Trough

  • In addition, this year, the monsoon trough — an east-west low-pressure area extending from the heat low over Pakistan to head Bay of Bengal – remained to the south of its normal position for majority of the days in July and in August, so far.
  • The low pressure systems did not move along Bihar, Jharkhand and Uttar Pradesh.
  • Such unfavourable conditions contributed to high rainfall deficits throughout the season.
  • The monsoon trough’s location, oscillation, and duration over a specific location, all directly affect the rainfall activity over the regions exactly to the south of its position.
  • That is, when it is located to the south of its normal position, there is active or vigorous rainfall over most parts of central, peninsular India regions. When it shifts to the north of its normal position or lays along the Himalayan foothills, Uttar Pradesh, Bihar, Jharkhand, West Bengal and the northeastern states benefit.

So, what should farmers do?

  • In UP and Jharkhand, the Agriculture Meteorology division has suggested the use of short duration rice varieties and have encouraged cultivation of red gram.
  • Farmers have been encouraged to opt for inter-cropping.
