Reducing Urban Entropy Employing Nature-Based Solutions: The Case of Urban StormWater Management

This paper presents the theory behind the concept of low-entropy cities based on the second law of thermodynamics. This concept aims to provide a bridge among different approaches on city sustainability studies, highlighting the links between natural processes and the socio-ecological complexity of urban systems. A practical low-entropy application is then proposed for urban storm water management, examining the planning of nature-based solutions with the support of a modelling approach. A further novelty of this work is the attempt to combine entropy with resilience assessment for urban green infrastructure planning.
