Natural rubber cultivation in Thaïland

carte thailande2

Did you know that Thailand is the world's leading producer and exporter of natural rubber? With 30% of the world production, its harvest mobilizes 1.5 million farmers. The production, trade and processing of natural rubber supports 10% of the Thai population.


Did you know that one hectare of Hevea produces 2 000 kg latex per year? It represents 5 to 7 kg per tree. Heveas start producing latex after 5 to 6 years and during about 25 years.

To harvest latex, farmers take off the bark of the tree on the half of its circumference, then make a deep bleeding on the trunk with a special knife. The slits are usually performed at night: latex flows better while the temperature goes down. Every night a farmer bleeds 1 000 trees.
