We live on the blue planet, with three-quarters of its surface covered by oceans. Yet, we also increasingly live on the urban planet. Those two realms are profoundly disconnected. Yet, cities impact oceans in many significant ways, direct and indirect. Cities can and must begin to include oceans in their planning, what might be called blue urbanism, and a natural extension of the emphasis given to urban greening and green urbanism in many cities today.
What would it mean to live in cities where we care about and feel connected to oceans? Blue Urbanism challenges us to imagine how terrestrial urbanites can also be understood to be citizens of the sea, citizens and inhabitants of the blue world, and as such care for and steward over this most amazing of Earth’s realms.
