Ecological and Digital Transition in Cities: Measuring Ecosystem Services for Urban Planning and Design argues that urban planning must be reoriented through the joint ecological, digital and inclusive transition of cities, placing ecosystem services at the centre of design, governance and regeneration. Edited by Francesca Moraci, Carmelina Bevilacqua and Pasquale Pizzimenti, the volume responds to climate change, biodiversity loss, urban inequality and post-pandemic uncertainty by proposing adaptive and regenerative planning models. Its central idea is that cities should not be planned only through land use, infrastructure or economic competitiveness, but through the measurable relation between natural, built and social capital. Ecosystem services—air purification, climate regulation, food provision, water management, biodiversity, recreation and cultural benefits—are treated as operational tools for urban resilience and human well-being. The book gives particular importance to data-driven methods, big data, artificial intelligence, urban informatics, indicators, local climate zones and spatial modelling, arguing that digital technologies can help planners evaluate ecosystem service supply, demand and vulnerability. At the same time, it warns that ecological transition must be socially fair: green certification, regeneration and technological innovation can reproduce spatial inequality if they are not governed through inclusive policy. Its main contribution is to translate natural capital into planning indicators capable of guiding adaptive urban transformation, linking green infrastructure, urban metabolism, mobility, social cohesion, climate adaptation and governance. The conclusion is that the future of urban planning depends on integrated methods able to monitor change, revise strategies and align ecological restoration with digital intelligence and social justice.
