Other countries can protect themselves from major disasters by adopting—and adapting as necessary—some of the measures taken by Japan, and by understanding the strengths and weaknesses of Japan’s response to the GEJE. To help them do that, the Learning from Megadisasters initiative will provide data, analysis, and insight in printed and Web-based formats (including e-learning), in face-to-face activities, in seminars presented through the good offices of the Global Development Learning Network,1 and through a dedicated community of practice—all designed to build the capacities of government decision makers and other stakeholders in developing countries.
