Despite years of discussions to phase out paddy in Punjab, owing to its impact on groundwater, latest data shows that the paddy crop area still dominates agriculture in the state. Paddy is currently grown over 87% of the total area under kharif crops (June-October) in Punjab, according to data shared by the Punjab Agriculture department which notes that in the current 2022-23 kharif season, the area under paddy, was 3.13 million hectares out of 3.59 million hectares under kharif crops.
Over 35 years ago, in 1986, a government report on crop diversification, led by economist S.S. Johl, recommended at least 20% area under paddy and wheat, the dominant crops in Punjab, should be shifted to other crops for ecological sustainability, primarily prevention of groundwater depletion. The predicted impact of a large paddy area on groundwater has come true – currently 80% of the state is in the red zone due to the overexploitation of groundwater.
Punjab is currently the highest extractor of groundwater in the country and 97% of it is being used in irrigation, mainly for paddy, as per Central Ground Water Authority’s last available Ground Water Estimation report 2020. The seriousness of the problem was apparent in a statement by the monitoring panel of the National Green Tribunal (NGT) under Chairman Justice Jasbir Singh (retd) when it stated last year in May that if the present rate of extraction continues, the state would be left with groundwater for 17 years, till 2039.
Paddy is a water-intensive crop and needs around 5000 litres to grow a kilogram of rice. Punjab had a diversified agriculture landscape before two cereal crops – paddy and wheat – were promoted as part of the union government’s thrust to attain food security, later pegged as Green Revolution.
The area under paddy in the state, which was 0.2 million hectares in 1960-61, had increased almost five times to 1.1 million hectares by 1980-81, data taken from Punjab State Farmers’ and Farm Workers’ Commission’s 2018 report revealed. The report has been removed from the public domain by the Punjab State Farmers’ & Farm Workers’ Commission after a new panel was announced recently. At the time of Johl’s report in 1986, the paddy area kept increasing and touched 2 million hectares by 1990-91, an addition of almost one million hectares in one decade.
In an interaction with Mongabay-India, Johl, now 92, said he had advocated the promotion of alternative crops since he could foresee the fast depletion of Punjab’s underground water on which irrigation of paddy was mainly dependent.
However, farmers have been incentivised to stick with paddy production because of a few reasons, note various experts and government officials: there is almost 100% procurement of paddy at centre’s minimum support price (MSP); harvesting and sowing has become easier; and agriculture extension services have helped to increase per hectare production.
With paddy being cultivated over 3.13 million hectares in the current kharif season (June-October) and wheat crop cultivated in 3.5 million hectares in the current rabi season (November-April), the two cereal crops occupy almost 84% of the total gross cropped area of 7.8 million hectares in the state.
The impact on groundwater
Punjab’s wheat-paddy cycle consistently contributed to the centre’s food security needs for the last several decades. In the 2021-22 procurement season, Punjab contributed more than 12.5 million tonnes or 20% of total rice procurement of 56.81 million tonnes to the central pool managed by the Food Corporation of India. Similarly, the state contributed around 53% of wheat to the central pool in 2022.
However, this high cultivation of paddy is fast-depleting groundwater in the state. As per the CGWA data obtained under the RTI Act in January, 119 out of 138 blocks in Punjab are currently in the over-exploited category as far as groundwater depletion is concerned. According to the agency’s reply, the situation is more serious in central and southern parts, including Patiala, Sangrur, Barnala, Mansa, Bathinda, Moga, Ludhiana and Jalandhar – where paddy is the dominant crop in the kharif season. The state’s average groundwater depth at which water is available has crossed 70 meters(200 feet). In the last decade (2011-2020), overall depletion was 2-4 metres.
“There are areas in southern districts of the state where the groundwater is not available even at 150-200 metres (450-600 feet),” Punjab’s former irrigation secretary KS Pannu told Mongabay-India. He said if this trend is not reversed anytime soon, Punjab will be left with no groundwater to irrigate its crops. “If the water level drops below 300 metres in the next 18-20 years, water quality becomes highly contaminated and unsuitable for irrigation or drinking. Even the cost of extraction will be too high for farmers,” Pannu said.
While quoting from CGWA’s groundwater estimation report 2020, Pannu explained that the state is over-extracting 14 billion cubic metres (BCM) of groundwater annually. The annual extractable groundwater recharge in Punjab from different sources like rainfall, etc., is 20 BCM, but the state is using 34 BCM of groundwater, he said.
Factors sustaining paddy in Punjab
Responding to a question by Mongabay-India, on why the state failed to phase out paddy despite its adverse impact on groundwater, Gurvinder Singh, director of the department of agriculture in Punjab, reiterates the reasons that farmers stick to paddy farming: 100% procurement of the paddy at centre’s MSP and consistent economic returns for the farmers.
While procurement data for the 2022-23 season is not officially available yet, the centre spent Rs 1.45 trillion on procuring 75 million tonnes of paddy in the 2021-22 season, followed by 89 million tonnes of paddy at Rs 1.69 trillion in 2020-21 season.
Gurvinder Singh said in the 2018 and 2019 crop seasons, the department convinced a section of farmers in districts most-affected by groundwater depletion, to grow maize in place of paddy. But the farmers returned to paddy the next season as there was MSP for maize. “Even if the government starts procuring alternate crops like maize or pulses at MSP, it will still be insufficient to match the income farmers get from paddy,” he said. He explained that farmers’ current earnings from paddy are between Rs. 45,000 and 50,000 per acre. On the contrary, per acre income from pulses or maize, even after MSP realisation will be Rs 30,000 to 35,000. “The income gap is basically due to low yield in alternate crops and further lack of proper sowing and harvesting techniques,” Singh added.
Another indirect reason that paddy has been able to sustain is that water for its irrigation is highly accessible at no cost. Punjab offers free power for agriculture since 1997, allowed farmers to extract as much water from the ground through tubewells for free. The data obtained from Punjab Electricity Corporation’s Engineers Association revealed that power consumption in the agriculture sector in Punjab has almost doubled in the past two decades, an increase from 6,049 million units in 1997-1998 to 11,226 million units in 2018-19. This also increased the Punjab government’s subsidy bill from Rs 6.58 billion in 1997-98 to Rs. 72 billion in 2022-23, which is projected to touch Rs. 75 billion in the current fiscal year, data revealed further.
In 2017, Punjab State Farmers’ and Farm Workers’ Commission recommended the withdrawal of free electricity to medium and large farmers and the use the money saved on subsidies to start an income support programme to promote alternate crops. The move, as per a report, could save at least half of the subsidy bill of the state government. But, these recommendations have not yet been implemented.
Economist S.S. Johl told Mongabay-India that free power was one of the major hurdles why Punjab could not phase out paddy. “It led to wastage of groundwater and increased its consumption manifold. This must stop before it is too late,” said Johl.
“Punjab’s problem is severe. We do have solutions to overcome them. But we lack political leaders who have farsightedness and can gather enough political will to take hard and strong decisions,” said Johl.
