As mangroves are one of the most prominent coastal ecosystems in tropical and many subtropical areas around the world, it is likely that the impact by climate change on mangroves will have greater economic and social significance, when compared to the effect of climate change on most other coastal ecosystems. This report surveys the scientific literature and estimates how the various components of the mangrove ecosystem may respond to expected climate change. It also considers the impact of climate change on the use of mangroves by man and suggests various policy options that could be used by governments to prepare for the predicted climate change.
