EAFES Symposium ES03 -- 19 March 9:00-12:00 Room D

Effect of physical environment and grazing intensity on productivity and biodiversity in East Asian grasslands

Organizers: HIROTA Mitsuru (Univ. of Tsukuba), HE Jingsheng (Peking Univ.), TANG Yanhong (NIES, Japan)

Grasslands cover about half land area of East Asia. Most of these grasslands are located in Qinghai-Tibetan Plateau and Mongolia Plateau. Ecosystems on the plateaus are experiencing dramatic environmental changes resulted from both climate changes and human activities. This symposium, being supported by Japan Science and Technology Agency and Ministry of Science and Technology of China, will focus on environmental issues in relation to carbon cycle and water balance in East-Asian grasslands. The topics, including both reviews and case studies, covers recent studies on hydro-ecological issues; various effects of climate change and livestock grazing on plant species diversity, ecosystem stability and production-biodiversity.
