Despite global shorelines that are increasingly threatened by rising seas and storms, coastal development is, ironically,
all the rage — just look at Dubai’s massive artificial island, shaped like giant palm trees and a map of the world. It’s a potent signal of wealth and power; after all, island-building is inherently political. That fact seems to have escaped the U.N. when it drafted its
United Nations Convention on the Law of the Sea, signed in 1982. Although artificial islands are addressed in the policy, it’s clear the organization didn’t foresee any major diplomatic problems arising from their construction.
In a world that is rapidly changing both physically and politically, that’s going to be a problem, and it’s going to get worse.
Few things cause more international tension than access to coasts, oceans, and their resources, and climate change promises to intensify that conflict. The laws of supply and demand suggest that as
coastal real estate dwindles, its value will go up, creating economic and political pressure to not only shore up existing coasts, but create new coastal real estate altogether — this, while coasts and islands elsewhere are disappearing.
