Climate adaptation and disaster risk reduction policy frameworks emphasize the importance of engaging vulnerable communities in data creation and utilization to enhance resilience.Yet, empirical evidence on how capacity strengthening and community data generation can improve post-disaster recovery processes remains limited.To address this gap, this article investigates the post-disaster recovery process in the El Pacífico self-built neighborhood, located at the hillslopes of the rural-urban border of Medellín, Colombia.Utilizing participatory action research and documentation analysis, we examined documents related to the response and recovery committee (called "Mesa de Atención y Recuperación") established following a severe flooding event.Our analysis reveals a lack of clearly defined procedures for engaging affected communities in the post-disaster efforts.However, we provide evidence that initiatives promoting equitable governance through capacity strengthening and community data generation, supported by our project, have effectively empowered community members, amplifying their voices in the negotiation with municipal authorities.These findings offer valuable insights that can inform more equitable future policies and practices in disaster risk reduction and climate adaptation with increased recognition and representation of marginalized urban residents.
