Urban development on water is combined with ecological development. Ecological structures offer habitat for (under)water species and provide other ecosystem services such as nutrient recycling. Food production is also included in the concept. Nutrients consumed by people are used to grow algae in floating systems. Algae are used as a base for biofuel and feed production. Feed is fed to fish grown in aquaponic systems. In this way local food is produced. Floating innovations related to food, energy production, infrastructure and ecological development can be integrated in the concept. The impacts on the environment and the aquatic life are evaluated using innovative monitoring systems such as underwater drones equipped with sensors and cameras.
