Monsoon Begins Retreat as India Braces for Significant Seasonal Deficit
NEW DELHI: The southwest monsoon, the lifeblood of India’s agricultural economy, has officially commenced its withdrawal from the country. According to the India Meteorological Department (IMD), the retreat began this Saturday in west Rajasthan, slightly delayed from the historical normal date of September 17.
As of September 19, the withdrawal line has been marked across specific regions including Ramgarh, Mohangarh, Phalodi, and Khajuwala. Meteorologists anticipate that weather conditions will remain conducive for a further pull-back across additional segments of Rajasthan, Punjab, and the Saurashtra and Kutch regions over the coming three to four days.
A Season of Rainfall Deficiency
While the withdrawal process is expected to conclude by October 15, clearing the way for the onset of the winter monsoon in peninsular India, the overall performance of the summer season remains a cause for concern. Nationwide, cumulative rainfall from June 1 through September 19 shows a persistent deficit of 15%.
The geographical spread of this shortfall is notably broad. Fourteen states—including agricultural powerhouses like Punjab, Haryana, and Bihar, alongside all five peninsular states—have recorded a rainfall deficit exceeding 20%. Experts project that by the time the season officially concludes on September 30, India will likely face an overall deficiency of over 10%. In meteorological terms, a deficit of this magnitude is classified as a drought year, highlighting the severity of the moisture stress experienced across large swathes of the country.
While a low-pressure area and a subsequent depression currently forming over the east-central Bay of Bengal are expected to bring much-needed precipitation to east India and coastal Odisha in the coming week, it is unlikely to bridge the significant cumulative gap.
Agricultural Implications and Crop Yield Risks
The monsoon’s performance is intrinsically linked to the El Niño phenomenon—the warming of ocean surface temperatures in the equatorial Pacific—which frequently results in weakened monsoon winds and elevated temperatures across India. This year’s performance has closely tracked those patterns, fueling uncertainty in the agrarian sector.
Despite a relatively stable start to the kharif sowing season, industry analysts warn that the country is not entirely out of danger. While official data indicates that the total area sown for kharif crops has declined by just over 1% compared to last year, the details reveal a more concerning trend. Water-intensive crops, particularly paddy, have seen a acreage decline of nearly 4%.
Beyond the immediate impact on kharif yields, the skewed timing and regional unevenness of this year’s rainfall pose a substantial threat to the upcoming rabi (winter) crop season. Soil moisture levels, which are critical for the sowing of winter wheat and pulses, may be insufficient in several regions due to the premature monsoon retreat and the preceding rain deficiencies.
As the curtains draw on a challenging monsoon season, the focus of policymakers and farmers alike now shifts to managing water resources to mitigate the long-term impact on national food security and agrarian economic stability.
