The COP3 Meeting held in 1997 adopted the Kyoto Protocol to set the target for reducing the emission of Green House Gases for the coming decade. However, it is still anticipated that the regulation of the emission is not sufficient, and that global warming would proceed. Therefore, adaptation is an important field as a response to global warming and climate change. In the present paper, the status of the international activities on the adaptation is first introduced. Since this subject is relatively new, the studies are at the beginning stage. Some discussions are also made to clarify the points to be studied in the future to develop appropriate adaptive strategies. These points include classification of adaptation options, who will adapt, relation between the adaptative policies to climate change and other threats, criteria for the adaptation assessment, and threshold of the climate change.
