WHERE DO WE FIND

THE SPACE ?

Looking to the 21st century:

60% of the cities still need to be built!Today’s cities only provide 40% of the space that will be required and the largest share of

these cities is located right near the coast

• Fossil fuels → Renewables

• Fishing → Farming

• Flooding → Floating

• Competing → Co-existing

• Exploiting → Co-creating

• Polluting → Regenerating

• Working → Living
