Expansion of rubber (Hevea brasiliensis) in Mainland Southeast Asia: what are the prospects for smallholders?
The rubber tree is native to the humid tropics and has traditionally been cropped in the equatorial zone between 108Nand 108S; in mainland Southeast Asia this includes portions of southern Thailand, southeastern Vietnam, and southern Myanmar. In the early 1950s, the Chinese government began to invest in growing rubber in environments perceived to be ecologically marginal and eventually established state rubber plantations in areas that lie as far north as 228 north latitude.
