Floating wetland systems potentially can provide a diverse set of ecosystem services that collectively improve urban resilience. Despite the growing studies and use of floating wetlands in temperate and subtropical climates, the design of floating wetlands in tropical climates is still understudied. This paper therefore aims to identify the research gaps in landscape planning and synthesize the design typology that can be applied to tropical urban conditions. The purpose of this research is i) Identify opportunities and challenges in applying floating wetland systems for landscape planning and design, ii) synthesize the design typology that can be applied to urban tropical climate conditions and iii) demonstrate the application of ecological wetland principles for the built environment. This research uses a mixed methods approach by including both a narrative review based on 67 peer-reviewed articles as well as case studies from tropical climates. The review captures the challenges and opportunities of designing ecological floating wetlands in terms of multifunctional usage, site limitation, cost effectiveness, social benefit, and ecological habitat creation. For design typology of floating wetlands in a tropical climate, we discuss design components based on size, floating mat types, structures and materials, planting design, and additional technology. While the first case study showcased a design for an ecological floating wetland, the second case study illustrates how mathematical modeling can guide sizing and performance assessment in planning floating wetland implementation. Ecological floating wetlands can provide a positive impact to the urban environment under tropical conditions, but the main research gaps include an incomplete understanding of contaminant uptake rates associated with different plants, required maintenance of the systems, plant robustness, and community appreciation.
The problem of the lack of inclusive public space in the fringes of Bangkok, Thailand, is related to multiple factors in urban development. The study-area of the Pathum Thani province offers a summary of the critical consequences of the urban development in the past decades. The partial transformation of some environmental tracks onto an urbanized system allows the creation of a nonhomogeneous privatized continuous built surface. The conditions of these urban areas suffer from vehicular traffic, car dependency, absence of differentiated mobility, limited walkability, and lack of public spaces. The research aims to bring these areas to a higher level of inclusion, accessibility and overall quality by rethinking the existent public spaces, creating the grounds for the design of inclusive and accessible park. To reach this objective, the study explores the topics of public space, park, accessibility and inclusivity for disabilities to establish some principles for future design approach for Thaklong–Klongluang, a study-area located in the Pathum Thani Province. Characteristics, features, weaknesses and existing parks of the study area are demonstrated in the subsequent section. The results’ discussion relates all the aforementioned topics, defining the guidelines for the creation of inclusive and accessible parks in the six existent sites of the study area. Because of its premises, besides being based in a specific location, the article aims to be a valid reference for the areas which present similar features and critical points.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
