Climate-Resilient Schoolyards: Comparative Strategies and Priorities for Urban Climate Adaptation

Schools are increasingly recognised as critical public infrastructure for urban climate adaptation, particularly in heat-vulnerable and park-poor neighbourhoods. This study examines schoolyards as distributed cooling systems, social spaces, and educational landscapes and proposes an integrated decision support approach for programme comparison and prioritisation. A comparative review of nine international schoolyard transformation programmes (Paris, Barcelona, Madrid, Milan, Rotterdam, Los Angeles, New York, Melbourne, and Santiago de Chile) was conducted using municipal plans, reports, and implementation guidance. Design strategies, governance configurations, and monitoring approaches were synthesised through a CAME (Correct, Adapt, Maintain, Explore) framework. Building on this synthesis, a Multicriteria Analysis framework was developed to support prioritisation across four criteria families: environmental and climatic performance, social and educational equity, urban integration and accessibility, and feasibility and co-benefits. The results highlight a recurrent toolkit of interventions—depaving, tree planting, shade provision, cool and permeable surfaces, nature-based drainage systems, and monitoring practices—that is consistently associated in the reviewed evidence with improved thermal comfort, stormwater performance, biodiversity, and community use beyond school hours. It is concluded that a combined CAME–Multicriteria Analysis structure provides a transferable basis for transparent, criteria-based prioritisation of schoolyard interventions by local governments and school authorities.
