CHIANG RAI – Rising diesel prices are putting real pressure on rice farmers and combine harvester operators across Chiang Rai. What used to be a manageable part of the farming season has become a heavy burden, forcing changes in how fields get harvested and how much it costs.
Combine harvesters run almost entirely on diesel. When fuel was cheaper, operators could keep fees reasonable. Now, with diesel at around 48.4 baht per liter — up sharply from about 30 baht per liter not long ago — the numbers simply don’t add up the same way.
Summary of the Crisis
The agricultural sector in Chiang Rai and Northern Thailand is grappling with a significant shift in operational costs:
- Fuel Price Surge: Diesel has jumped from 30 baht to 48.4 baht per liter.
- Harvesting Fees: Rates have risen from 500 baht to nearly 700 baht per rai.
- Narrowing Margins: Machine operators are earning less profit despite higher fees, while farmers face dwindling returns on their crops.
The Cost of Powering the Harvest
For people like Mr. Sitthiporn Kreuachaiya, a prominent combine harvester owner in the region, the math of farming has changed overnight. Combine harvesters are the lifeblood of the modern Thai harvest, but they are thirsty machines. These massive mechanical beasts run exclusively on diesel, and their efficiency is now being eclipsed by the price at the pump.
“Previously, our biggest headache was actually getting the fuel,” Mr. Kreuachaiya explained. He noted that in the past, strict restrictions made refueling a logistical nightmare. While those supply limits have vanished—allowing operators to buy fuel in large gallons without a cap—the new problem is far more permanent: the price tag.
With diesel now sitting at 48.4 baht per liter, the cost to fill a combine’s tank has become a staggering expense. When compared to the previous price of 30 baht, the nearly 60% increase has sent shockwaves through the local agricultural economy.
The Domino Effect on Harvesting Fees
In the world of farming, when the cost of input rises, the price of the service must follow. To keep his business afloat, Mr. Kreuachaiya has been forced to adjust his rates.
Comparison of Harvesting Costs in Chiang Rai
| Expense Category | Previous Rate | Current Rate |
|---|---|---|
| Diesel Price (per liter) | 30 Baht | 48.4 Baht |
| Harvesting Fee (per rai) | 500 Baht | 650 – 700 Baht |
While a jump to 700 baht per rai might seem steep, Mr. Kreuachaiya insists it is a matter of survival rather than greed. In fact, he explains that even with the higher fee, his actual profit is lower than it was when fuel was cheap. The overhead costs have swallowed the difference.
The most difficult part of the situation is the “ceiling” on what farmers can afford to pay. Agriculture is a low-margin business, and the rice farmers of Chiang Rai are already dealing with unpredictable weather and fluctuating market prices for their grain.
“I cannot increase the fees any further,” Mr. Kreuachaiya said. “If I go higher than 700 baht, it would severely impact the farmers. They wouldn’t have anything left.”
This creates a “lose-lose” scenario. If harvester operators raise prices to cover their fuel, the farmers go broke. If operators keep prices low, they cannot afford to maintain their machines or pay their staff. This stalemate is threatening the efficiency of the harvest season, as some farmers may hesitate to hire professional harvesters, potentially leading to crop waste.
Why Fuel Prices Matter for Thailand’s Food Security
Chiang Rai is one of Thailand’s most important rice-growing provinces. When harvesting becomes more expensive in the North, the effects are felt across the country. Higher production costs can lead to:
- Reduced Household Income: Local farming families have less money to spend in their communities.
- Increased Debt: Many farmers rely on loans to cover harvesting costs, and rising fees increase their debt burden.
- Market Pressure: Eventually, these costs may be passed down to consumers, though rice prices are often capped by the government, leaving the farmer to “absorb” the loss.
As the harvest season continues, the community is looking for ways to mitigate the damage. Some are calling for government subsidies on “purple” agricultural diesel, while others are looking into more fuel-efficient machinery.
For now, the people of Chiang Rai are doing what they have always done: helping each other get through a tough season. Mr. Kreuachaiya’s decision to cap his fees—even at the expense of his own profit—shows the tight-knit nature of the farming community.
However, as long as global fuel prices remain volatile, the golden fields of the North will continue to face an uncertain future. The harvest will go on, but the cost of bringing rice from the field to the table has never been higher.
