Water was the first major design theme influencing the expansion and crisis of urban centers. Nowadays, it is the parameter for evaluating the effectiveness of all actions to counter climate change.

On Hoperaperta, Alfonso Femia writes "On Water, in the shape of sentiment at La Biennale dello Stretto”

"It is the behavior of water that decrees the success or failure of strategies of urban forestation, of reducing climate-altering emissions, of mitigation and adaptation actions, retreating from littorals and balancing its presence at different latitudes." AF
