peri-urbanization in southeast asia
OverviewOver the past half century, the five countries of mainland Southeast Asia – Cambodia, Laos, Myanmar, Thailand, and Vietnam – have witnessed major shifts from predominantly subsistence agrarian economies to increasingly commercialized agriculture and industrialized societies. Current research on land cover change in Southeast Asia, however, fails to provide an integrated understanding of where change is occurring, whose lives are affected, and how these people, in turn, may drive land cover change in other locations. This project brings together a multidisciplinary team to focus on the following objectives: (1) produce regional maps of land cover change, with increased detail for boom crops and periurban areas, 2000-2012; (2) broadly document the political economic drivers of boom crops and urbanization by synthesizing information from secondary sources; and (3) produce an integrated understanding of the location of boom crop expansion and urbanization, as well as the political economic drivers of these changes. At the local scale, research objectives include: (1) use expert knowledge to identify a sample of forests, boom crops, and periurban areas in Cambodia, Laos, and Vietnam undergoing rapid change; (2) conduct focus group discussions and household interviews in these sites to identify how land uses have changed and if any displaced land uses have occurred; and (3) produce maps of land cover change for 2000-2012 in the sample sites, with a specific focus on mapping rubber, pulp and paper, and coffee plantations in periurban areas by integrating satellite imagery, census data, and expert local knowledge.
