Climate Change Adaptation research programs

Research Managing Director: HIJIOKA Yasuaki

In order to provide scientific support for our mission to promote climate change adaptation, we will engage in research and technological development in the area of observation and monitoring of climate change impacts, improving methods for assessing the impacts of climate change and climate change adaptation strategies by organizing climate change adaptation research program. Outcomes of this research program will contribute to policy decisions by governments, such as the preparation of reports on the comprehensive assessment of climate change impacts and making changes to National Adaptation Plan and also to initiatives by other key players, including local governments for climate change adaptation through publication of the outcomes via A-PLAT and AP-PLAT.

Research programs on climate change adaptation

Project summary

Research project for the observation, monitoring and detection of climate change and resultant impacts (PJ1)

PJ1 Principal Investigator: OGUMA Hiroyuki

We will collect and organize long-term monitoring data in relation to natural ecosystems (terrestrial ecosystems, coastal-area/enclosed-sea ecosystems, marine ecosystems, coastal ecosystems, and lake/watershed ecosystems), air pollution (ozone, particle matter (PM), etc.) as well as data on associated meteorological factors (e.g. air temperature, precipitation, wind velocity, humidity, etc.) to analyze the relationship between medium and long-term trends of climate change and the impacts of it.

We will also research to clarify the mechanisms behind the impacts to climate change in order to support detected climate change impacts. Moreover, we will develop effective monitoring methods in order to observe the impacts of climate change.

Observation data and climate change impacts detected in various fields as a result of these activities will be publicized via A-PLAT and AP-PLAT to disseminate this information to a broader public audience and promote a further understanding of the observation, monitoring and detection of climate change impacts.

Research project on improving methods for predicting the impacts of climate change (PJ2)

PJ2 Principal Investigator: HANASAKI Naota

We will assess the impacts of climate change in a variety of fields (e.g. water resources, terrestrial ecosystems, crop yields, and human health) and at a variety of levels (from the global level to municipalities). We will then refer to monitoring data and mechanisms behind the impacts of climate change, etc. provided as a result of PJ1, and work to establish an advanced means of assessing the impacts of climate change in consideration of impacts resulting from socio-economic changes in consideration of a range of climatic factors, including temperature changes, changes in the amount of rainfall, rises in sea-levels and ocean acidification.

Through these activities, we hope to contribute to the consideration of adaptation methods, such as improving methods of assessing the impacts of climate change and identifying priority areas and to contribute to furthering an understanding of climate change risks among society by publicizing established climate scenarios and the results of impact assessments via A-PLAT and AP-PLAT.

Research project on adaptation strategies in consideration of social changes (PJ3)

PJ3 Principal Investigator: TAKAHASHI Kiyoshi

We will organize elements, concepts and assessment methods of climate change adaptation to investigate how to accumulate and communicate scientific information related to adaptation and understand inhibitory factors against the perception of climate change risks and the implementation of adaptation measures. In addition, we will collect and consolidate socio-economic scenarios currently under development and develop and provide socio-economic scenarios that will allow for the assessment of climate change impacts and adaptation/mitigation measures by Japan and local governments.

Moreover, we will develop systems that allow for the quantitative assessment of the effectiveness of adaptation measures that combine statistical analytical methods, including areal statistics, based on statistical data, and measured activity volume and environmental data. And we will develop framework to assess climate change impacts and adaptation measures based on Quality of Life (QOL) indices in consideration of the knock-on effect to local communities and the economy and conduct analysis using such systems and framework. In addition, we will clarify the effect that the various impacts of climate change occurring outside Japan will have on production and consumption activities in Japan through international input-output analysis and applied general equilibrium model analysis, etc.

Through these activities we hope to contribute to formulating effective adaptation strategies and promote the development of adaptation plans and the formulation of adaptation measures by local governments, and communication with stakeholders by publicizing obtained scientific knowledge and developed systems on A-PLAT and AP-PLAT.
