The power of cities over the seas

The Vibrant Oceans Initiative, backed by Bloomberg Philanthropies and implemented by groups including Oceana, Rare, the Wildlife Conservation Society (WCS), and Environmental Defense Fund (EDF), has concentrated on national fisheries reform. Yet many of the fisheries it seeks to improve supply coastal cities whose markets shape demand. Where urban buyers reward transparency and sustainability, reforms on the water gain commercial traction. The relationship runs both ways: effective management can stabilize supplies for cities, while market pressure can reinforce compliance at sea.
