摘要：Urban flood risks and vulnerability in coastal cities have been directly linked to unplanned urbanization and development solutions that isolate ecosystem peculiarity. Whereas, Sustainable Urban Drainage Systems (SUDS) as Nature-Based Solutions are capable of reducing the impact of urbanization on flooding. This study investigated public perceptions of Nature-Based Solutions to flood management in Lagos-State, Nigeria. Data for this study were obtained from primary and secondary sources. Using a multi-level approach, 339 respondents participated in the mailed survey randomly administered across the five (5) administrative divisions of Lagos-State and results were analyzed using tables and Chart. Ecosystem services connected with Nature-based Solutions (NbS) and design strategies for Sustainable Urban Drainage Systems (SUDS) were reviewed from secondary sources. Results obtained revealed a high level of awareness of the determinants of flood risks. Most of the respondents (73%) consider NbS applicable in Lagos State. Although, a larger percentage has a fair knowledge of NbS as a concept, when provided with specific examples, 68% indicated that they are familiar with the methods. The result further revealed that majority (85%) are strongly disposed to „trees planting‟ as a SUD strategy. 71% will consider permeable pavements and rainwater harvesting while 61% are inclined to rain garden, 47% and 35% will consider green roof and wetlands respectively. Analysis of survey revealed that the greatest barrier to implementing SUDS is the lack of awareness of the value and multiple benefits of NBS. We conclude that there is a clear need for the design of the built environment of Lagos coastal city, particularly housing to integrate NbS and optimize its traditional function for improved urban flood resilience. Therefore, a consistent design approach and framework is required and thus calls for further studies. .
