A study of time-series data derived from satellite images tracked land use and land-use change in Southeast Asia from 2003 to 2014. The study focused on an area more than twice the size of France where land-use change has been most dramatic—all of Cambodia and Laos, most of Vietnam, northeast Thailand, Shan State in Myanmar, and Xishuangbanna Prefecture in southern Yunnan, China. During the 11-year study period, the area planted with rubber more than quadrupled, so that by 2014, rubber accounted for 8 percent of total land cover in the region. Most of this expansion came at the expense of the region's native forests.
