		| Scope | Interactions between water/chemical cycles and terrestrial ecosystems are the most important base supporting our irreplaceable planet. However, the geoscience for climate and tectonic activities and ecosystem sciences for biological responses are respectively allocated to different sections as 'Physical Sciences and Engineering' and 'Life Sciences' in Science Council of Japan, suggesting that an enhancement of the collaborations is needed for this interdisciplinary subject to establish a significant position in the scientific and social communities. Because a gap between large-scale water/chemical cycles and small-scale biological processes is particularly deep, a study strategy is strongly required to integrate them.
   Based on this consideration, sessions with specific subjects have been convened in JpGU since 2010. We have decided a general session on role of terrestrial ecosystems in the water/chemical cycles without any specific subject. To create a real interdisciplinary session is expected through addressing not only basic sciences but also applied sciences for developing a sustainable society based on balancing the use of natural resources and the conservation of environment. | 
	
		| Notes | Strictly keep your persentation time of 12 minutes with the discussion of 3 miniutes. The poster core time is from 6:15pm, and a meeting on JapanFlux is also held after our session in the same room. Please join both. |
