Published in Sustainability, this research paper focuses on pathways towards the digital and green transition. We assess a generic pathway for the transformation of industry ecosystems in cities and regions based on processes of “prioritisation”, “ecosystem identification”, and “platform-based digital and green transition”. Our interest in the transformation of activity-based ecosystems by the twin transition, digital and green, is both theoretical and methodological. Continue reading
Contemporary smart cities involve a very high number of software applications and hardware devices that connect to the physical and social space of cities and form complex ecosystems in different knowledge and activity domains (transportation, logistics, healthcare, housing, industry, governance, social care, and many more). In this context, smart cities can be considered multi-layered complex systems, systems of systems, that provide ubiquitous access Continue reading
This paper published in Land describes a model to assess the feasibility of transition of city districts to self-sufficient net-Zero-Energy Districts (NZEDs), based on locally produced renewable energy suitable for cities. It also aims to identify threshold conditions that allow for a city district to become a self-sufficient NZED using smart city systems, renewable energy, and nature-based solutions. Continue reading
