LEISZ,* KONO Yasuyuki,** Jefferson FOX,*** YANAGISAWA Masayuki† and Terry A. RAMBO†† Humans have been influencing changes in land cover through their changing patterns of land use since the invention of agriculture. The initial small footprints left by agricultural settlements have grown larger overtime and today it is estimated that roughly 50% of the earth’s land surface has been affected and transformed by human activities [Vitousek et al. 1997; Haberl et al. 2007]. This impact is not static, but rather is constantly changing as resource use patterns, farming systems, and settlement patterns change. Since the 1970s, with the application of information from satellite sources to the study of worldwide land use and land cover changes, interest in questions of how and why land use is changing and the impacts of these changes on the natural and built environment has grown. Studies focusing on land use and land cover change have been grouped under the title of “land change science,” an inter- disciplinary field that investigates and attempts to understand the dynamics of land use and land cover changes within coupled human-natural systems [Turner et al. 2007]. The papers that make up this special issue fit within the scope of this field and attempt to address one of the central questions that land change scientists are addressing today: causes of land use change. Turner et al. [2007] note that most of the proposed causal variables of land use change are proximate factors, such as immigration, subsistence farmers’ impacts, deforestation, or local common property resource management strategies [Lambin and Geist 2006] and that more distant factors, such as nat ional policies, tend to be difficult to connect empirically to land use change outcomes. This special issue attempts to address this issue within land change science by focusing on one region of the earth, the montane uplands of Vietnam, Laos, Cambodia, and Hainan Island (China), in Southeast Asia that has * Department of Anthropology, Colorado State University, Fort Collins, Colorado, U.S.A. ** 河野泰之, Center for Southeast Asian Studies, Kyoto University e-mail: [email protected] *** East-West Center, U.S.A. † 柳澤雅之, Center for Integrated Area Studies, Kyoto University †† Faculty of Agriculture, Khon Kaen University, Thailand 237 東南アジア研究 47 巻 3 号 witnessed an
