ENTRANCE - Overview

 

ENTRANCE is a so-called Joint Laboratory of IMK-IFU and the Institute of Atmospheric Physics, Beijing, funded by the Helmholtz Association of German Research Centers and the Chinese Academy of Sciences for the period 2008-2013 to address scientific research questions that arise from the fact that China is facing serious environmental problems such as eutrophication, desertification, erosion or air pollution. The environmental situation may even get worse in view of the predicted global and regional changes in environmental conditions. For adapting and combating global change effects on the environment in China, mitigation strategies and adaptation options have to be developed, including strategies to increase carbon sequestration and to reduce the emissions of NH3, NOx and N2O and nitrogen losses due to leaching and run-off.

The overall goals of ENTRANCE are

  • to evaluate the impacts of land use/cover changes on biogenic C and N cycles and the associated biosphere-atmosphere exchange for selected ecosystems and regions in China, 
  • to quantify the resulting environmental consequences and feedback mechanisms of the biosphere, in particular of climate change,
  • to explore different land use and land management scenarios on site and regional scales by using GIS-coupled biogeochemical models in order to contribute to the establishment of strategies to combat, mitigate or adapt to climate changes and, thus, to provide recommendations for the sustainable development of China’s environment.

 

ENTRANCE will do this in the framework of different pilot studies, using state-of-the-art experimental and modelling approaches. This joint laboratory will allow for further intensification of the cooperation between two institutes with an already long-term cooperation history in the field of environmental research in China, contribute to capacity building and increase environmental awareness. By joining forces on the basis of an overarching science plan, ENTRANCE will further increase the nationally and internationally acknowledged competence and visibility of both institutes for global change and biosphere research.

 

Pilot studies

 

  • Elucidation of pathways of excess nitrogen in Chinese agriculture with stable isotopes (Yanting, Sichuan Province, Contact: Nicolas Brüggemann)
  • Mechanistic modelling of biogeochemical C/N fluxes at the landscape scale for China (Contact: Klaus Butterbach-Bahl)
  • Plant VOC emissions in China (Beijing, Contact: )
