From Crisis to Growth: Pre-Disaster Planning as a Catalyst for Sustainable Innovation and Circular Economy in European Cities

The proposed contribution analyses how short- and long-term strategies in urban planning can foster urban resilience and a circular economy by comparing technological measures, nature-based solutions and integrative communication processes. In examining how authorities engage the public to address emerging hazards, this study demonstrates the role of pre-disaster planning in catalysing sustainable innovation. We highlight communication as the key driver for inclusive, resilient long-term policy. Our case studies include Graz (AT) and Ljubljana (SLO). Though confronted with similar ecological and socio-demographic challenges, the two cities address these challenges in markedly different ways, reflecting culturally biased divergent policy priorities and communication strategies. Using Graf et al.’s 2026 introduced Aware–Prepare–Act (APA) lens as a heuristic, the paper conducts a comparative policy analysis of two contrasting urban governance models. The paper tests the thesis that technological upgrades (e.g., expanding tram networks, cycling infrastructure, digital tools and AI) only produce urban resilience when anchored in sustained communication and participatory processes, a relationship made visible through an overarching APA lens on prevailing practices. In addition, inclusive, participatory formats are crucial for the achievement of a Social Licence to Operate, needed for boosting involved stakeholders’ acceptance to redesign cities for enhanced biodiversity, integrate green infrastructure, and organizational learning on all levels.
