A Monsoon Divided
As the southwest monsoon season draws to a close, the national picture is one of stark regional divides. Overall, rainfall has been below normal. By early September, the country faced a seasonal deficit, with some forecasts predicting the shortfall could
reach 15%. The distribution has been the primary concern. While recent rains helped reservoir levels recover in western and central India, key agricultural regions in the north and south remain significantly dry. States like Andhra Pradesh, Karnataka, and Punjab have seen significantly less rain than usual, which is a major red flag for the upcoming Rabi sowing season. This geographical split is the defining feature of the 2026 monsoon, creating pockets of high risk even as other areas appear stable.
The All-Important Reservoir Levels
The winter harvest, which includes vital crops like wheat, mustard, and gram, is highly dependent on irrigation, and that irrigation water comes from reservoirs filled during the monsoon. According to data from the Central Water Commission, as of mid-September 2026, water storage in India's major reservoirs was below both last year's levels and the ten-year average. Nationally, storage stood at around 70% of capacity, which is nearly 7% below the normal level for this time of year and over 20% lower than in 2025. The situation is particularly concerning in the southern region, where reservoirs were only about 54% full, well below the normal level of 73%. In the north, key reservoirs like Bhakra were also holding significantly less water than the previous year. This deficit in stored water directly translates to less available irrigation for farmers preparing to sow their winter crops.
Impact on Key Rabi Crops
The consequences of low reservoir levels and depleted soil moisture are most acute for the Rabi season's main crops. Wheat, the cornerstone of India's food security, is heavily reliant on irrigation, particularly in the northern states of Punjab and Haryana where reservoir levels are below last year's highs. Insufficient water can lead to a reduction in the total area sown and impact the final yield. Mustard, a major oilseed, and gram (chana), a key pulse, also face uncertainty. These crops are often grown in rainfed or minimally irrigated areas, making them vulnerable to poor pre-sowing soil moisture. The uneven rainfall means that while farmers in central India might have adequate conditions, those in parts of the south and north could face a difficult decision: whether to sow at all, or to risk planting with insufficient water reserves. Farmers may be forced to shift to crops that require less water, potentially altering the country's overall food grain and oilseed production numbers.
The Economic Ripple Effect
The fate of the Rabi harvest extends far beyond the farm gate. A weak harvest could put upward pressure on food inflation, which has remained a concern. Lower production of staples like wheat and pulses would mean tighter supply, potentially leading to higher prices for consumers. For farmers, a poor yield threatens to reduce incomes, especially if they have already faced losses from the Kharif (summer) season due to erratic rains. The government's procurement operations and its ability to maintain buffer stocks could also be challenged. While Minimum Support Prices (MSPs) for Rabi crops were increased to provide a safety net for farmers, the effectiveness of this measure depends on a healthy harvest and robust procurement. Ultimately, the uneven monsoon creates economic uncertainty, impacting everything from rural demand for goods to the country's overall agricultural growth.
