This is a report on research road map providing a way forward for achieving a better estimation of the global carbon cycle and for contributing to international climate policies. The road map was reviewed by a committee including experts from meteorology, ecology, agriculture, and social science, which was established in the fiscal year of 2012 supported by the Environment Research and Technology Development Fund, Ministry of the Environment, Japan. Primary issues and tasks were identified that must be undertaken to accelerate the development of an effective system for observing and evaluating the impacts of climate-carbon cycle feedbacks.
