Abstract:

Global Terrestrial ecosystem has experienced a complex set of multiple changes in climate, atmospheric CO₂ concentration, nitrogen deposition, tropical ozone, and land use and land cover change (LULCC) in the 20^th century, and has been projected to continue experiencing these changes through this century. Much concern has been raised regarding the impacts of climate change and increasing atmospheric CO₂ on water resource and food security. However, it is short of investigation on the quantitative understanding and assessment of how Climate Change and Increasing Atmospheric CO2 Concentration have affected global Net primary Productivity (NPP), evapotranspiration (ET) and global Water Use Efficiency (WUE) in the terrestrial biosphere. By using the Dynamic Land Ecosystem Model (DLEM) driven by spatially-explicit information on climate, atmospheric CO₂ concentration and other environmental changes, we assessed the spatial and temporal patterns of net primary productivity, evapotranspiration and water use efficiency across the global land surface in the past and future.
