Governance challenges for tropical nations losing fish species due to climate change

Climate change is driving fishery stocks out of their historical ranges. Along with the management challenge of species entering new jurisdictions, the exit of species from countries’ waters poses distinct threats to those resources and the economies that depend on them. We show that this risk is particularly acute in the tropics, where projected exits are highest and entries are fewest. We find that existing policy frameworks are poorly equipped for this challenge, and we suggest a way forward that draws on climate policy.
