Rain watch for Sept 7-13: Monsoon weak, crop yields uncertainty rises

According to Barclays, with IMD’s forecast for ‘below normal’ rainfall for most parts of the country in September (barring the eastern region), the rainfall deficit may not be reversed completely in the rest of the season. Earlier, IMD forecasts estimated monthly rainfall to be normal at 91-109 percent of LPA in September with above-normal rainfall in the east and Northeast, but likely below-normal rainfall for the rest of the country.

Reservoir levels declined again with inadequate rainfall. As of September 6, storage in key reservoirs stood at 62 percent compared to 63 percent in the previous week. This is also lower than last year’s level at this stage of the monsoon season which was at 74 percent of available capacity and lower than the historical average for this point in the season.

Current reservoir levels are 84 percent of the 10-year average. The drop in reservoir levels is now a material concern for the rabi winter crop, and may also spark fears of water rationing going into the festive season.

Across the regions, the reservoir levels this year have been far lower than last year’s levels: Northern region (82 percent versus 87 percent last year), Central (71 percent versus 81 percent last year), Western (71 percent versus 89 percent) and Eastern region (45 percent versus 62 percent) and Southern region (48 percent against 91 percent).

Kharif sowing is complete, but lack of adequate rainfall for more than a month may lead to uncertainty for crop yields. Apart from soybeans and pulses, the yield of irrigation-intensive sugarcane also could be threatened, particularly owing to deficient rainfall in major producer states like Maharashtra, says Barclays. 

Area sown with sugarcane as of September 8 is higher than last year and compared with the historically normal area. Low rainfall and likely intensification of El Niño phenomenon towards the end of the year poses a risk to the food inflation trajectory, considering already elevated inflation in pulses and cereals. Still, elevated rice sowing may mitigate some of these risks, especially given the export restrictions already in place.

Overall total kharif sowing as of September 8 stands at the same level as last year levels at 1088.5 lakh hectare. Sowing of coarse cereals has improved by 0.5 percent supported by higher sowing of maize (2.9 percent) and bajra (0.5 percent). 

Acreage of pulses is still lagging behind by 8.6 percent led by lower sowing area of arhar and urad. Additionally, sowing area of cotton has declined by 1.5 percent compared to last year levels. Even area sown for oilseeds is down by 0.9 percent.
