Mangrove ecosystems play an important role in buffering communities from the impact of coastal hazards. The Asian Tsunami in 2004 provided valuable lessons on the role that mangroves play in coastal protection and on the intrinsic value of maintaining healthy mangroves. This book captures the lessons learned and knowledge gained in Thailand from post tsunami research conducted on the linkages between mangrove ecosystems and the livelihoods of coastal communities. The lessons from this work portray how applied research contributes to the post-disaster environmental rehabilitation and its contribution to good coastal management.
