Summary of Key Points
Chinese consumers have achieved “durian freedom”—import volumes have increased by over 50% in the first half of the year, with wholesale prices as low as 13.8 yuan per kilogram and supermarket prices of 19.9 yuan readily available. However, durian farmers in Southeast Asia are facing losses and some are even turning to banana cultivation to make up for their losses. This reflects a typical dilemma in agricultural production: a surge in demand leads to policy and capital incentives for increased planting, which in turn results in overproduction, plummeting prices, and a decline in quality (where inferior fruits drive out the better ones). This is an example of the “fallacy of composition,” where individual rationality leads to collective irrationality, highlighting the long-term risks and lack of standards associated with decentralized farming patterns.
I. Durian Freedom: Chinese Demand Fuels Expansion in Southeast Asia
How strong is China’s demand for durians? In the first half of 2026, imports reached 1.07 million tons, a 50% increase from the same period last year. This has presented Southeast Asian countries with an opportunity to generate foreign exchange through exports:
- Vietnam: The planting area has increased fivefold in the past decade, reaching 192,000 hectares in 2026, with expected production of 2-2.1 million tons this year (compared to 1.8 million tons in 2025). Farmers are cutting down rubber trees and converting rice fields to plant durians; some villages have seen significant income gains from durian cultivation, with earnings per mu (a unit of area) higher than those from coffee and rubber. For individual farmers, choosing to plant durians is rational.
- Thailand and Malaysia: These countries have also expanded their durian production, with Malaysia aiming to export $229 million worth of fresh durians to China by 2030.
However, the problem arises when no country coordinates production capacity, and all players flood the Chinese market, leading to an oversupply.
II. Why Are Farmers Losing Money? The Agricultural Fallacy of Composition Hides a Common Problem
The “fallacy of composition” occurs when everyone’s individual actions seem rational, but collectively they lead to a wrong outcome:
- Supply Exceeds Demand: In 2025, the combined production of durians from Thailand, Vietnam, and Malaysia was nearly 4 million tons, while China’s imports were only 1.868 million tons. Even when considering domestic and other markets, supply still exceeds demand.
- Lag in Production: Durian trees take 5-7 years to bear fruit. Trees planted during the high-price period from 2019-2021 are now bearing fruit, coinciding with an oversupply and resulting in plummeting prices.
- Small Farmers Can’t Afford the Risks: Many farmers are inexperienced or use urban capital; high initial investment in water, fertilizers, and maintenance costs, coupled with falling prices, lead to losses. Some even abandon their farms to work elsewhere and rely on banana cultivation to make up for their losses.
III. Even High-End Varieties Fail: A Vicious Cycle of Inferior Fruits Driving Out the Better Ones
Does planting high-end varieties like “Matsan King” and “Black Thorn” guarantee profits? Not necessarily:
- Quality Issues: High-end durians are valued for their ripeness, sugar-to-acid ratio, and low pesticide residues, but small farmers lack the necessary skills. For example, Vietnamese durians, due to high alkalinity and cadmium levels, had only 35,000 tons exported to China in the first four months of 2025 (many orchards lack the necessary certification).
- Low-Quality Fruits Drive Down Prices: Inexpensive, non-genuine Matsan King durians fetch no more than 10 ringgit (16.7 yuan) per kilogram, dragging down the overall price of high-end varieties. Even qualified, high-quality fruits suffer from unstable prices due to market panic.
- The Loss of Prestige: Increased production has led to chaotic harvesting standards and lax quality control, damaging the reputation of high-end brands.
IV. Common Challenges in Agriculture: Long Production Cycles and Decentralized Production
This is not unique to durians; the same issues apply to domestic crops like Gannan navel oranges. In 2025, the brand value of Gannan navel oranges was 69.2 billion yuan, but the local price dropped below 0.8 yuan per kilogram (from previously 2-3 yuan). The reasons include:
- Long Production Cycles: It takes years for trees to bear fruit, and by the time they do, market conditions have changed.
- Decentralized Farming: Hundreds of thousands of farmers operate independently, without unified standards or coordination in production capacity. For example, although Gannan navel orange production has increased, the national citrus market is dominated by 80% of mid-ripening varieties sold in winter, leading to price competition.
- Weak Resistance to Risks: Farmers are at the mercy of weather, market, and policy changes, with no collective bargaining power.
V. A Solution: Learning from the Navel Orange Cooperative (Navel Orange Growers’ Cooperative)
In 1893, California faced citrus overproduction, and farmers formed the Navel Orange Growers’ Cooperative, transforming over 6,000 small farms into a cohesive community:
- Unified Standards: From planting to harvesting, all processes are standardized to ensure quality.
- Unified Sales: The cooperative manages orders and builds a brand to prevent price undercutting.
- Risk Sharing: Farmers collectively address market fluctuations, such as using juice production to absorb excess supply.
This shows that agriculture must move away from the fallacy of composition by adopting more coordinated approaches, including unified standards, branding, and better matching of supply and demand, so farmers can work together more effectively.
Conclusion: The Durian Tragedy Is Not an Isolation
It highlights a common issue in agriculture: long production cycles versus rapid market changes, and the conflict between individual rationality and collective irrationality. To prevent farmers from suffering due to low prices, governments, cooperatives, and businesses must work together to transform decentralized farming into a more cohesive industry. Behind the “durian freedom” lies the tears of farmers—this should not be the norm in agriculture.
