Super El Niño 2026 Is Coming: What South Asian Farmers Need to Know About Irrigation

In early June 2026, NOAA scientist Nathaniel Johnson warned that the Pacific is shifting into Super El Niño territory. If you farm anywhere between Punjab and Phnom Penh, that’s not abstract climate science. It’s a direct threat to your next harvest.

I’ve spent the past week reading everything I can find on what’s happening on the ground in South Asia. The picture isn’t pretty. Wells are running dry in Haryana. Canals in West Bengal are delivering half their normal flow. And monsoon forecasts keep getting revised downward. But here’s what nobody’s saying loud enough: the farmers who are going to lose the least aren’t the ones with the biggest landholdings or the deepest pockets. They’re the ones who got their irrigation sorted out before the drought hit.

What the Data Actually Says

Let’s start with the numbers, because they’re sharper than any headline.

The India Meteorological Department has been walking back its monsoon projections for three months straight. Ground reports from Punjab and Haryana, India’s breadbasket states, describe wells that used to hit water at 40 feet now needing to go past 120. A June 10 India Today investigation found farmers across both states reporting failed canals, collapsing groundwater, and polluted supplies. These aren’t future scenarios. This is now.

Meanwhile, the Pacific Ocean is running 1.5°C above normal in the key Niño monitoring region. Past Super El Niño events (think 1997-98 and 2015-16) knocked Indian agricultural output down by anywhere from 4% to 8%. Rice yields dropped 12% in some districts during 2015-16. Sugarcane took a similar hit. And this year’s event could persist into 2027, which means two consecutive growing seasons under stress.

The FAO’s most recent crop monitoring bulletin flagged below-average soil moisture across eastern India, Nepal, and parts of Bangladesh. That’s the pre-monsoon baseline. If the rains underdeliver, those moisture deficits compound fast. I’ve seen soil moisture maps from the Indian Agricultural Research Institute that show some districts in eastern Uttar Pradesh already running 30% below the ten-year average for June. That number should have farmers losing sleep.

Why Drip Irrigation Matters More During El Niño

When water gets scarce, farmers do what farmers have always done: they flood-irrigate whatever they can and hope for the best. It’s the instinctive response. It’s also exactly the wrong move.

Flood irrigation in a drought year wastes water that you don’t have. Typical field application efficiency for surface irrigation runs about 50 to 60 percent. That means nearly half of what you pump never reaches the root zone. Drip systems run at 85 to 95 percent efficiency. In a normal year, the difference is a line item on your water bill. In an El Niño year, it’s the difference between a crop and a bare field.

Here’s a concrete example. A vegetable grower in Maharashtra with one hectare of tomatoes needs roughly 500 to 600mm of water per season. With flood irrigation and 55 percent efficiency, that’s more like 1,000mm you’re pulling from your well. With drip at 90 percent efficiency, you’re pulling 580mm. That’s a 420mm savings. And in a drought, you don’t have 420mm to spare.

I talked to a supplier who works with cotton farmers in Gujarat. He told me that during the 2015-16 El Niño, his drip irrigation customers harvested at about 80 percent of normal yields. His flood irrigation customers? Less than half. “The difference,” he said, “wasn’t the technology. It was that the drip farmers could stretch their water. The flood guys ran out in February.”

What makes drip systems so effective during drought isn’t just the water you save today. It’s that drip lets you irrigate smaller volumes more frequently, keeping soil moisture steady instead of swinging between soaked and parched. Plants under drip don’t experience the stress cycles that make them drop flowers or abort fruit. In hot, dry El Niño conditions, that consistency matters more than total water volume.

Three Things South Asian Farmers Should Do Right Now

Monsoon planting windows are opening in the next few weeks. If you haven’t thought about your irrigation strategy yet, here’s what I’d do:

1. Pressure-test your water source. Don’t assume your well or canal supply will hold. Measure your flow rate now and compare it to the same month last year. If it’s down more than 15%, you’re in the danger zone. Plan your crop mix accordingly: fewer water-hungry crops, more pulses and millets, and definitely no paddy unless you’ve got a backup plan.

2. If you’re running drip irrigation, check every emitter. An El Niño year punishes sloppy maintenance. A system running at 90% of designed uniformity is fine in a normal season. In a drought, those under-watered spots turn into dead zones. Walk your laterals. Replace clogged emitters. Flush the lines. Do it before planting, not after.

3. Mulch aggressively. Soil evaporation spikes during dry, hot El Niño conditions. A 5cm layer of straw or plastic mulch can cut evaporation by 30 to 50 percent. Combined with drip irrigation underneath, you’re getting nearly all your water into the plant instead of the atmosphere. It’s cheap insurance.

The Cost Question Nobody Wants to Ask

I know what you’re thinking. Installing drip irrigation costs money, and when you’re staring down a bad season, spending feels wrong. Let me give you the math the way I see it.

A basic drip system for one hectare of row crops in India runs about ₹35,000 to 50,000 (roughly $420 to 600 USD). Government subsidies through PMKSY can cover 45 to 55 percent of that in most states. Your out-of-pocket might be ₹18,000 to 27,000. Now think about what you stand to lose if your monsoon crop fails entirely: input costs for seed, fertilizer, labor, and land prep, plus the revenue you don’t earn. For one hectare of cotton, that’s easily ₹60,000 to 80,000 gone. For vegetables, it’s more.

The drip system pays for itself in one bad year. In a Super El Niño year, it might pay for itself three times over. And unlike a good monsoon, it doesn’t disappear. You’ve got it for 5 to 7 seasons minimum, and the subsidy programs in India, Bangladesh, and Nepal have been getting more aggressive about pushing adoption. Several state governments in India have raised their subsidy share above the standard PMKSY ceiling specifically because of the 2026 El Niño forecast.

What I’d Avoid

A few things I see farmers doing that make El Niño losses worse:

Don’t drill deeper hoping to chase the water table. It’s a race to the bottom, literally. Every neighbor who drills deeper pushes the table further down for everyone else. Invest in efficiency instead of depth.

Don’t switch entirely to drought-tolerant crops without irrigation. Sorghum and millet can handle less water than rice, sure. But even they have limits, and El Niño heat stress hits them harder than you’d think. Keep some irrigation capacity even for “drought” crops.

Don’t wait for government canal water. By the time the shortage is official, it’s too late to respond. Assume canal deliveries will be below normal and plan from there.

The Super El Niño of 2026 will not wait for anyone to get ready. The farmers who come out of this intact are the ones who act like the drought is already here. If you’re still on flood irrigation, at least price out a drip system for your highest-value crop. You don’t have to convert the whole farm overnight. Start with the crop that earns you the most. That’s where the numbers make the easiest case. Go from there.
