Rainfall deficit in 37% districts of India despite ‘normal’ monsoon; September crucial: IMD data

By Abhishek Waghmare

After two consecutive droughts, India received normal rainfall — 2 percent less than the 100-year average —by the end of August 2016, but within that normality, more than a third of the country is short of rain, according to India Meteorological Department (IMD) data.

In 610 of 641 districts for which data are available, 389 districts received normal or excess rain, while 221 received “deficient” or “scanty” rain in the first three months of the four-month-long monsoon season. This means September rainfall will now be important to make up for these widespread deficits.

WHAT THE TERMS MEAN

Excess rainfall: more than 20% of normal

Normal rainfall: -20% to +20% of normal

Deficient rainfall: -20% to -40% of normal

Scanty rainfall: less than 40% of normal

Still, these are best rains since 2013, when India received 14 percent more than the average rainfall of the June-August period.

As much as 16 percent of the country’s area is now rain deficient, according to IMD data.

The sowing of kharif (summer monsoon) crop was 5 percent more than normal by August-end because more than half of India’s districts received normal rain, reiterated by the Reserve Bank of India in its 2015-16 annual report: “As on 18 August, 2016, the cumulative rainfall was at its long period average (LPA) level as against 9 percent below LPA in the corresponding period of the previous year, leading to an increase of 6.5 percent in kharif (summer monsoon crop) sowing, thus far.”

North East India, Punjab, Haryana, Gujarat short of rain

The monsoon deficit is greatest in North East India, which is between 30 percent and 40 percent — repeating the situation in 2013 — followed by Punjab, Haryana, Gujarat and Kerala, where the deficit is between 20 percent and 30 percent of normal.

Rajasthan, Madhya Pradesh and Maharashtra have received 20 percent more rain than normal.

Though the area sown is more than normal, some crops have taken a hit.

While 40 percent more pulses were sown than normal till the end of August, cash crops like sugarcane and cotton were 15 percent short of normal.

Extreme rainfall events in central India, the core of the monsoon system, are increasing and moderate rainfall is decreasing — as a part of complex changes in local and world weather — according to a clutch of Indian and global studies reviewed by IndiaSpend in April 2015.

Increasingly variable rainfall implies wide deficits within a ‘normal’ monsoon

Over a third of India — 221 of 610 districts — is short of rain in a year when the government’s weather agency, the IMD, and private weather agencies, such as Skymet and Weather Risk Management Services, and international monitoring agencies, such as the European Centre for Medium-Range Weather Forecasts and the International Research Institute for Climate and Society, USA, had predicted an above-normal monsoon for 2016.

The three monsoon months of 2016 bettered the three deficit years of 2012, 2014 and 2015, but lagged 2011 and 2013, which were normal monsoon years, with respect to the proportion of districts facing rain shortfalls.

Rains were scarce in a fourth of districts in 2011 and 2013, a third of districts in 2016 and half of India’s districts in 2012 and 2014.

Kharif (summer) sowing above normal but might fall short of season average

The normal sowing area in India till August-end is 97 million hectares, against which 102 million hectares has been sown for the kharif season 2016.

Sown area by the end of the kharif sowing season is 106 million hectare, which is achieved normally by the first week of September.

Irregular rainfall in the cotton-belts of Maharashtra and deficient rains in Gujarat has resulted in less-than-normal sowing of cotton.

In Maharashtra, sowing of jowar (sorghum) — a traditional non-irrigated crop — dipped 20 percent, from 6.1 lakh hectares to 4.9 lakh hectares.

The sowing of soyabean, a relatively new entrant on farms, is growing. The area under soyabean in Maharashtra was 3.9 million hectare, 0.5 million above the average of 3.4 million hectare, as of August-end.

“The cost of cultivation for cotton is high, and has risen especially after 2008-09,” Ayaz Khan, a soyabean and tur cultivator from Vidarbha region in Maharashtra told IndiaSpend.

Unirrigated cotton produces a fourth to a fifth of the yield of irrigated cotton; 200 to 300 kg per acre against 1,000 kg per acre, said Khan. “Soyabean gives you assured output in less than three months without irrigation. Further, tur and soyabean require less human effort to cultivate.”
