Vivienda líquida y sinhogarismo oculto: Innovación en políticas urbanas mediante co-creación en Tarragona

Resumen

The phenomenon of “liquid housing” represents one of the most pressing challenges for contemporary housing policy in European cities. Defined by forms of housing insecurity such as squatting, illegal subletting, forced shared occupancy, overcrowded or substandard housing, liquid housing blurs boundaries between stability and homelessness. With an emphasis on the policy co-creation process, this research draws upon mixed methods, including surveys, stakeholder interviews, and scenario-based workshops to generate actionable evidence, foster multi-level stakeholder engagement, and co-create local policy solutions in response to the multifaceted challenge of liquid housing. The findings reveal the centrality of data-driven awareness, stakeholder integration, and governance reform for achieving resilient, inclusive policy innovation in the context of fragmented competences and persistent social vulnerability. The article concludes that sustained progress against liquid housing demands a holistic, rights-based, and cross-sectoral approach, rooted in collaborative intelligence and empowered civic participation, to ensure dignified housing for all in medium-sized cities such as Tarragona, the city aimed by the study.
