On February 18, the US sent naval ships to the South China Seas, an area of armed tension over rich but dwindling fishing grounds (among other things). The following day, a newspaper headline proclaimed the risk of “global fish wars” sparked by climate change and rising nationalism.
Is the world on the brink of interstate fish wars? Probably not: a large-scale military dispute is not likely to erupt over tuna, and conflict over fish affected by climate change could occur over a long time horizon. But as fish become more difficult to find, understanding the links between fisheries and violent armed conflict is increasingly important.
