| Outline of Final Research Achievements |
We conducted aerial photo analysis, surveying, aerial photographing, wave observation and water quality observation, and questionnaire and interview survey on mangrove marshes in Thailand, Indonesia and Vietnam and examined the conditions for sustainable use of mangrove marshes. From the long-term aerial photograph analysis, we examined the disappearance factors of mangrove and conditions effective for conservation. Evaluation of mangrove restoration project using bamboo fence and revetment showed the effectiveness of enhancing sediment accumulation by sufficient dissipation and human intervention until seedling settlement. In addition, remarkable coastline retreat was found to be affected by changes in sediment supply, relative sea level rise, and illegal mangrove logging, and possible adaptation measures taken by local people and governments were discussed.
