EXAMINING IMPACT AND EFFECTIVENESS OF COASTAL ADAPTATION USING GREEN INFRASTRUCTURE AGAINST SEA LEVEL RISE

Abstract

 Sea level rise due to climate change may threaten humans living near coastal areas. To adapt to climate change, it is important to examine the effectiveness and cost of coastal protection. Coastal areas can be protected more efficiently and economically using both green and gray infrastructure, such as mangroves and sea dikes, along the coastline. However, few studies have examined the long-term feasibility and impact of adaptation measures at a global scale. Therefore, this study carried out an impact assessment of inundation and a cost analysis of such measures, focusing on 112 countries and regions containing mangrove forests. It was found that combining mangrove forests and dikes could be potentially effective in the global aggregates. However, the national feasibility of such measures depends on the country, which requires site-specific management solutions to accommodate local conditions.
