Abstract
Global warming and sea level-rise are projected to affect seriously on atolls, which are narrow and low-lying islets on coastal reefs. Accelerated coastal erosion or decrease of coastal vegetation would be critical problem for atolls. Then, we focused on land cover and vegetation in the coastal zone, and classified land use of the coastal zone on Majuro atoll. The feature of geographical features and land cover of the coastal zone was able to be divided by using ground truth data acquired in filed investigation, GPS-image, satellite image (IKONOS). Finally, it was proposed that the region where defense measures were necessary and the regions where current state was maintained.
