Impacts of Global Change on Water Resources in Dryland East Asia
The vast Dryland East Asia (DEA) area consists of several large geographic regions including the Qinghai-Tibet Plateau, Loess Plateau, and Mongolia Plateau. T he region is of great importance to the functioning of the earth system under a changing climate. In the past three decades, due to the unprecedented land use/land cover change, urbanization, industrialization and climate change, water stress in many areas in DEA have reached a dangerous level that threatened the sustainability of the region. In addition to reviewing literature for the causes of the water crisis observed in the region, as case studies, we examined water balances at a basin and regional scale using multiple modeling techniques, including a remote sensing-based EC-MOD model, a watershed water balance model (WBMPlus), and an evapotranspiration model calibrated for the Loess Plateau region.
