In: Proceedings of the 9th U.S. - Japan Workshop on Global Change: Carbon Cycle Management in Terrestrial Ecosystems, October 9-11, 2001, Tokyo, Japan. p.11-13. Interpretive Summary: This working group was assigned to identify key areas of bilateral interest regarding carbon management in cropland systems. Our meeting began with short presentations by the working group participants from Japan and the U.S. on their current research in agricultural systems and carbon cycle management followed by a group discussion of scientific issues of common interest.
Technical Abstract: Studies of cropping system and land-use management impacts on climate change are being conducted in both countries and a general consensus was noted that intensification of agricultural production will be required to achieve the food and fiber needs of a growing world population. Interactions among anthropogenic changes in atmospheric CO2 concentration, agricultural input management, and conservation strategies on primary productivity, carbon biogeochemistry, soil responsiveness and long-term carbon dynamics in arable soils systems were the focus of discussion. Strategies for augmenting soil carbon-sequestration and assessment of the impact of these strategies on perturbation of non-agricultural systems were also noted as key areas which will influence policy decisions designed to mitigate green house gas emission from agricultural activity.
