Implementation of zoning and land use measures for climate adaptation from cities across diverse contexts remains limited  owing to a range of challenges. A range of evidence from multiple locations indicates the challenges of mainstreaming land use planning for climate adaptation, including in Bangkok, Thailand , Legazpi City and Camalig Municipality in the Philippines , the USA , British Columbia, Canada , and Australia . Mainstreaming is hindered by a lack of clarity of implementation strategies for climate adaptation, insufficient funding, competing priorities , institutional challenges  study of 20 cities globally) and the need to fill data gaps and continuously update weather statistics  . At the same time, however, limited evidence from cities around the world such as the urban regions of Stuttgart and Berlin in Germany , Greater Manchester in the UK , and Colombo in Sri Lanka  reveals that risk reduction through zoning and land use can effectively protect and expand green infrastructure and soft land cover to alleviate pluvial flooding and decrease the urban heat island effect. This evidence points that one of the primary roles of land use planning is to guide the development of the urban form. As such, it underpins and establishes the basis for other infrastructure systems such as physical infrastructure and nature-based solutions .
