Research Keywords Water/energy/carbon cycles, Forestry, Universality and Diversity


The earth contains a truly diverse array of ecosystems, which are used and sometimes overused in order to facilitate human activity. As such, we can consider the environmental problems that exist in discrete areas as equally diverse. The students who take part in this GCOE will be able to directly experience some of the earth's diverse ecosystems and the environmental problems that are associated with them, and reflect the understanding that they gain in the field in their research findings.

Research Themes

  1. Characteristics of water, energy and carbon cycles in the north forest region, with specific focus on Siberia
  2. Extracting universality and diversity in the response to water, energy and carbon cycles in diverse climate zones, including (1) above.
  3. The impact of urban green spaces on urban climate
