May 22-27, 2007, Beijing, China
Ancient agricultural landscapes cover more than a quarter of China's total area. Interspersed with and adjacent to less disturbed areas, these dynamic and intensively managed ecosystems contribute disproportionately more to regional and global changes in climate, the biogeochemical cycles and biodiversity and are both the source and recipient of serious local and regional environmental impacts, including water and air pollution, deforestation, and habitat loss. This symposium will characterize the past and present ecological state of China's densely populated rural landscapes and discuss future trends and options for sustaining environmental quality and rural livelihoods in the face of increasing ecological demands on these systems.
Our symposium supports the conference theme: Ecological Complexity and Sustainability, by focusing on ecologically sustainable environmental management in some of the most complex and dynamic ecosystems on earth: China's rural landscapes. The session will focus special attention on the local, regional and global causes and consequences of changes in rural land management and resource use, including fertilizers, pesticides, fuels, and land development, clearing, tillage, tree planting and land abandonment.
