Prior traditional rubber cultivation of
Thailand in the south and the east has
gradually migrated to the new areas in the
northeast and the northern region. A
reason for the farmer is possibly adapting
to new source of revenue since there is a
challenge to grow other crops. Also a
balance of labor has been expending to
farming. In addition, growing rubber
plantation in the new area would be a
safety process to rubber production. There
was a feasible area to avoid a serious
outbreak of epidemic disease that occurred
in traditional area. The prior traditional
areas have been replanting the rubber with
an oil palm or other crops.
