Take it from someone who’s looked— sea level rise projections for Southeast Asia are almost impossible to come by. And yet this region is facing a future in which mega-cities are submerged, food sources such as coastal farms and auquaculture operations become inundated, fresh water becomes brackish, and mangroves are wiped out. The below maps illustrate the extent of the problem for mangrove forest preservation. These trees are highly effective carbon-sinks, fish nurseries, coastal buffers, and an important “canary in the coal mine” for biosphere resiliency. Special credit to Global Mangrove Watch for updated vegetation maps, and Climate Central’s CoastalDEM elevation maps which have proved essential to creating SLR projections for this under-studied region.
