For the analyses of climate change impacts, ‘scenario approach’ is frequently used. With the ‘scenario approach’, a limited number of plausible sets of future climate condition and non-climate condition are prepared and they are inputted into climate impact analyses models for projecting future plausible impacts. While ‘scenario approach’ is applied broadly in many impact analyses, it also has weak points. One of them is the relatively small number of scenario sets that can be examined, which often constrains utility of the results for the purpose of supporting policy assessment. For complementing the ‘scenario approach’, ‘impact response function’ approach has been applied in some studies. The ‘impact response function approach’ is a kind of sensitivity analyses with perturbating some important factors and archive the results of the analyses as a database, which could be utilized for further applied analyses.
