A Research through Designing approach was used to explore nature-based solutions (NbS) for flood management at the fluvial (regional) and pluvial (local) scales as part of a Smart District visioning study in a peri-urban area north of Bangkok, Thailand. The NbS visions were informed by community surveys (total n = 770) as well as in-depth, semi-structured interviews with community leaders and key stakeholders representing private sector business. Both fluvial and pluvial flooding commonly occur in the study area and the cost of damage incurred by individuals generally exceeds aid remuneration. The surveys revealed that flood insurance was not widely used as a form of resiliency to flood conditions. Furthermore, survey participants generally considered common space and green space unsatisfactory and inadequate to meet community needs. In light of these survey responses, example NbS visions were developed to address community concerns and promote well-being, while concurrently providing resiliency and improved ecosystem services through connectivity of blue and greenscapes. This case study provides a novel linkage between the concepts of NbS, Research through Designing, and Smart City/District, in exploring sustainable and resilient approaches to flood management in the context of tropical, Global South development and also provides a first step towards developing an NbS typology.
