Paper by Gabriela Manrique Rueda et al: “Science is essential for cities to understand and intervene on the increasing global risks. However, challenges in effectively utilizing scientific knowledge in decision-making processes limit cities’ abilities to address these risks. This scoping review examines the development of science for urban policy, exploring the contextual factors, organizational structures, and mechanisms that facilitate or hinder the integration of science and policy. It investigates the challenges faced and the outcomes achieved. The findings reveal that science has gained influence in United Nations (UN) policy discourses, leading to the expansion of international, regional, and national networks connecting science and policy. Boundary-spanning organizations and collaborative research initiatives with stakeholders have emerged, creating platforms for dialogue, knowledge sharing, and experimentation. However, cultural differences between the science and policy realms impede the effective utilization of scientific knowledge in decision-making. While efforts are being made to develop methods and tools for knowledge co-production, translation, and mobilization, more attention is needed to establish science-for-policy organizational structures and address power imbalances in research processes that give rise to ethical challenges…(More)”.
