以循環式水系統的重構進行韌性設計

Designing Resilience with Circular“Water Refactoring”

亞洲韌性設計（DRIA）國際研討會與設計競賽由新加坡國立大學於2015年發起，每年從聯合國國際減災策略組織所關注的國家，與美國洛克斐勒基金會發起的全球百座韌性城市之中選擇地點，作為探討與設計介入的主題基地，由超過十個國家的頂尖建築院校進行設計教學與競賽，並邀請風險或災害管理相關部門以及其他知名專家學者作為評審。2019年競賽的題目“Re-Think the Growing Chennai, Re-Imagine the Shrinking Pallikaranai Marsh”是以印度清奈市重要的沼澤濕地Pallikaranai Marsh為主題的韌性設計，都市急遽擴張下非正式聚落的入侵與佔據、區域垃圾掩埋場造成的汙染與水體破壞等等都是急迫的議題。成大團隊在競賽中獲得第一名，方案“Water Refactoring”水系統的重構，提出一種對基地敏銳且可行的設計，來創造一種基於社區的水資源、垃圾、與汙水處理系統。提案中“循環”作為實質與抽象概念上的策略，連結廟的水池與沼澤的水系統來建構小尺度空間與社交的融入，在都市涵構與生產地景之間，豐富的日常和循環式的連結使人們對沼澤的水文和生態動態有更深刻的感知與體認。循環的上游、下游關聯一體的設計，創造了新的原型，也可以被複製到其他沼澤區域的周邊，或是適應到清奈市其他的水體設計上。

2019 DRIA(Design Resilience in ASIA) design competition“Re-Think the Growing Chennai, Re-Imagine the Shrinking Pallikaranai Marsh”focuses on the Pallikaranai Marsh recovering in facing the increasing population and urban sprawl, in which informal encroachments and regional dump yard are contaminating and destroying the water bodies.“Water Refactoring”proposes a feasible and site-sensitive design that creates a community-based water, solid waste, and sewage management system. With circular as physical and conceptual strategies, the proposal provides small-scale spatial and social engagements with the temple tank and marsh water systems amending the practice of large-scale water and waste management. Richhabitual and circular re-connections of the urban context and productive landscape bring awareness to the hydrological and ecological dynamics of themarsh. The dual interconnected and circular up-stream and down-stream designs create a new prototype which is also replicable throughout the whole marsh region, and adaptable to other water bodies in Chennai.
