Abstract
Global warming and sea level-rise are projected to affect seriously on atolls, which are narrow and low-lying islets on coral reefs. Accelerated coastal erosin or decrease of coastal vegetation would be critical problems for atolls. In the present study, field investigation were carried out in order to collect the basic information for the sustainable land manegement on Majuro atoll against the global warming and the sea-level rise. The characteristics of the current field along the lagoon-side coast was clarified and a zoning map for the preservation of coastal vegetation at Laura was drawn through the field investigation.
