Over the last half-century, public policy has affected land-use practices across the borders linking China, Thailand, and Laos. Political and economic reforms have facilitated labor mobility and a shift in agricultural practices away from staple grains and toward a diverse array of cash crops, rubber being one of the foremost. China has promoted the conversion of forests to rubber agroforestry in southern Yunnan--profitable for farmers, but a concern in terms of biodiversity and long-term viability. In Thailand, the response is at the other end of the spectrum as the government's concerns about land-use practices and watershed management have led to policies that dramatically constrain land-use practices and limit tenure rights. In Laos the future is not yet clear. Government policies provide weak support for both private land ownership and protected areas. In a global environment where national policy has such a dramatic effect on land use and land cover, the factors behind land-use change merit close examination.
