Ocean and coastal ecosystems in the region will continue to be highly impacted by climate change . Coral reefs are projected to lose their habitat, change their distribution range and suffer more bleaching events driven by ocean warming. In the Representative Concentration Pathway  4.5 and RCP8.5 scenarios, by 2050, virtually every coral reef will experience at least one severe bleaching event per year . Under all RCP scenarios of climate change, there will be changes in the geographical distribution of marine species and ocean and coastal ecosystems such as mangroves, estuaries and rocky shores, as well as those species held in fisheries .
