Theme D：Precise impact assessments on climate change

To generate information that contributes to climate change risk management, it is important to perform a more detailed assessment of the impact, together with specifying the risks and understanding the probabilities. In this research theme, we are performing a quantitative impact assessment from a variety of perspectives including natural hazards, water resources, and ecosystems and biodiversity, using climate change prediction information as well as prediction information produced in this program. We are also performing a variation estimate of the expected risk value, an estimate of the uncertainty of that estimate, and an impact assessment on the worst-case scenario of a natural hazard. Next, using these figures, we perform a variation estimate of the socio-economic risk and aim to compile the basic information for adaptation strategies. With regard to natural hazards, in conjunction with proposing various basic approaches to the adaptation strategies, we aim to study assessment methods for comprehensive disaster mitigation measures that can alleviate a disaster to some degree when external forces occur that exceed the existing facilities plan, as part of the worst-case scenario. We also aim to construct a methodology for the economic assessment.
