Performance-led design process. Left: the current performance of a polder area managed by one sluice (arrow) within the floodplain of Antananarivo is assessed to guide design decisions. Middle: landscape architects intervene through precise topographic modifications to propose a new waterfront, reservoir, fishponds, canals, and fields derived from existing site forms. Right: the design process evolves through continuous iterations between topographic design and performance testing, using hydrological simulations to evaluate and refine proposals until a functional and satisfactory outcome is achieved. © ETH Zürich

Urban water management often prioritizes engineering efficiency over local ecological and social contexts. Landscape architects can leverage high-resolution modelling and vernacular intelligence to design resilient, culturally embedded solutions.
