MAINCODE announces the publication of a new scientific article titled “Urban Experimentation as a Driver of Climate Adaptation: A European Review of Climate Shelter in National Adaptation Policies and Practices” in the journal MDPI Sustainability, available in open access. The paper examines how climate shelter initiatives in European cities relate to national adaptation frameworks and assesses the level of integration between local practices and policy frameworks. The study contributes to a better understanding of the role of urban experimentation in climate adaptation across Europe. This publication represents an important milestone in MAINCODE’s contribution to scientific knowledge regarding the climate shelters across Europe.
