| The Environment Research and Technology Development Fund, is a public research fund administered by the Ministry of the Environment, Japan. Under this fund, research was carried out under 12 sub-themes to facilitate: ① Investigating impact assessment and effectiveness of adaptation measures based on national and regional climate change projections ② Scientific support to promote adaptation measures in local authorities, and ③ Contributions to planning and implementation of adaptation measures in the Asia-Pacific region - as part of the Strategic Research and Development Domain S-8 "Comprehensive research on climate change impact assessment and adaptation policies".
At the Intergovernmental Panel on Climate Change (IPCC) WGII Session held in Yokohama, Japan from March 25-29 and the 38th session of the IPCC, outcomes of global scale scientific studies on impacts, adaptation and vulnerabilities were made public.
Outcomes to date from projects with the objective of responding to the questions of addressing the issues of potential impact risks for Japan and the effectiveness of adaptation measures aimed at reducing attendant risks were introduced, as part of the IPCC's global endeavors to project future risk and propose countermeasures.
1. Project overview
This project aims to promote research to address new topics relating to countermeasures for global warming. Precision impact and adaptation assessment models (bottom-up models) are developed to establish the physical and economic impacts in precisely defined fields for Japan, while estimating the effectiveness of adaptation measures. Concurrently, top-down national impact assessment models are developed. By integrating these with the bottom-up models precision impact assessments on a national level are produced. By these means, the degrees to which future risk impacts can be reduced by the implementation of adaptation measures are assessed.
A monitoring methodology for different levels, including administrative and municipal areas is developed, thus elucidating global warming impacts for the administrative divisions of Japan. Furthermore, by developing easily-applicable methodologies to visualize the outcomes of projections on the regional level, regional adaptation policies are facilitated.
Finally, in order to prioritize adaptation measures for the Asia-Pacific region and to analyze cost effectiveness, standardized assessment indicators for effective adaptation to vulnerabilities and impacts in developing countries are developed on the basis of the research outcomes for Japan.
3. Summary of individual research outcomes
Reference materials (Japanese language only)
The climate scenarios (projections on future temperature rises, etc.) used in the comprehensive impact assessments in the above research outcomes reports, selectively applied existing low, interim and high level projections produced for the IPCC fifth assessment report on global warming. As such, it should be noted that this project does not constitute independently produced projections on future climate change.
