Economic Impacts of Cooperatives on Rubber Smallholders in Thailand: A Case Study in Bung Kan Province

Members delivering cup-lump to the rubber cooperative.

Research Background

 To increase rubber prices for rubber smallholders through improved rubber quality, the Government of Thailand established smallholders’ cooperatives in the 1990s and provided grants for smokehouses and other facilities for processing latex into ribbed smoked sheets (RSS) via unsmoked sheets (USS).
 Angthong and Fujita (2019) found that the cooperatives in South Thailand accomplished their goal as members obtained higher rubber prices owing to higher income/profit per unit area.
 In contrast, rubber smallholders in Northeast Thailand did not receive government grants for establishing smokehouses, and as a result, they mainly produce cup-lump and sell it through their cooperatives. What is the role of the cooperatives in such circumstances, and how can they compete with private-sector enterprises in that area?

Research Purpose

 To investigate 1) the current status of members and non-members in Northeast Thailand, and 2) the limitations/challenges faced by non-members in participating in the cooperatives in this area.

Non-members selling cup-lump at a private rubber shop.

Results

 Cooperative members are younger and more educated than non-members. Approximately 70% of rubber smallholders had rubber-planted land of less than 20 rai (3.2 ha). There appear to be differences in tapped rubber land between members (14.2 rai= 2.3 ha) and non-members (15.1 rai= 2.4 ha), but with no statistical significance.
 Regarding rubber products, both members and non-members sold only cup-lump. However, through an auction system and quality control at the cooperative, members enjoyed significantly higher unit prices (29.8 baht/kg.) than non-members (27.5 baht/kg.). Consequently, members’ income (7,738.4 baht/rai) and profit (2,167.1 baht/rai) per unit area were significantly higher than that of non-members (6,328 baht/rai for income and 1,086.1 baht/rai for profit). Moreover, although the cooperatives in Northeast Thailand do not face constraints on increasing the number of members as they have no capacity limitation for rubber auctions, many rubber smallholders are reluctant to join because the cooperative organizes rubber auctions only twice a month. Rubber smallholders who need immediate cash prefer to sell their rubber to private traders who buy rubber every day.

Plans for Further Research

 I have almost finished collecting the necessary data through field work for my doctoral thesis. I will begin writing the thesis by the next academic year. Meanwhile, I will also submit part of the thesis to some academic journals.
