Estimating the cost of coastal adaptation using mangrove forests against sea level rise

Sea level rise due to climate change poses a serious threat human populations in coastal areas. In planning possible countermeasures, it is important consider the potential economic risks and cost of any proposed adaptation. This paper examines effectiveness adaptation measures that combine mangrove afforestation (green infrastructure) dike construction (gray areas considered be at risk inundation. Based on data for 112 countries regions where forests are present along coastline, global benefit/cost ratio combination dikes approximately 1.5 times higher than dike-only protection. It was found this type multiple protection scheme can reduce number required overall
