Preface: At the Origin of Circularity

The planning of a "sustainable" development path for urban areas is a challenge both difficult and promising at the same time. In fact, heavily anthropized areas present the highest environmental and social criticalities and, nevertheless, are an ever-coveted source of opportunities and well-being. The book collects contributions on evaluation models in decision-making processes for the construction of circular urban systems in the digital era, with particular attention to the improvement of social and individual well-being.
