Study estimates global ecosystem value loss from sea level rise by 2100
A new study published in PNAS Nexus calculates the economic cost of ecosystem services lost to rising seas between 2030 and 2100.
Total annual value at risk
Researchers calculated that ecosystem service losses will reach 164.46 billion international dollars per year under a Middle of the Road scenario. This figure represents the combined loss of provisioning, regulating, habitat and cultural services across the globe.
Countries facing highest absolute damage
The analysis identifies China, Myanmar, Brazil, Russia and Vietnam as nations with the largest absolute losses. These countries face significant destruction of land areas including croplands and impervious surfaces.
Wetlands suffer greatest relative decline
Wetlands are projected to lose between 1.21 percent and 2.20 percent of their total extent by the end of the century. This percentage change is higher than losses recorded for other ecosystem types in the study.
