(Re)designing the Rules: Collaborative Planning and Institutional Innovation in Schoolyard Transformations in Madrid

Climate adaptation in urban environments is often constrained by rigid institutional rules and fragmented governance, which limit inclusive and context-specific planning of public spaces such as schoolyards. This study addresses this challenge by examining how collaborative planning can transform schoolyards, from asphalt-dominated, monofunctional spaces into green, climate-resilient community assets. The research employed the Institutional Analysis and Development framework within a qualitative case study design. Two public schools in the San Cristóbal de los Ángeles neighbourhood of Madrid served as case studies, with data collected through document analysis, participant observation, and interviews with municipal officials, urban planners, educators, and community members. Results indicate that the collaborative planning process reshaped rules in use, expanded the network of actors, and transformed decision-making processes. Existing rules were flexibly reinterpreted to allow new uses of space. Children, teachers, and residents became co-producers of the public space, expanding the governance network, where new deliberative practices emerged that improved coordination across people and organisations. These institutional changes occurred without formal regulatory reform, but with the reinterpretation of the game’s rules by each organisation. Thus, schoolyards can serve as laboratories for institutional innovation and participatory climate adaptation, demonstrating how urban experiments have the potential to catalyse not only physical transformations but also transformations in urban management.
