Archipelagic Ecologies

Long Island Scheme 1: a self-sustaining archipelago of biorock islands for coastal protection, water harvesting and ecological buffering.

This scheme proposes a dynamic, self-sustaining coastal protection and water-harvesting infrastructure through an evolving archipelagic system. Initiated by offshore biorock farms placed in high-current, deep-sea zones, tidal energy is harvested to stimulate rapid mineral accretion, producing structural biorock components. These are then transported inland to construct modular biorock embankment walls that enclose coffer-reservoirs—artificial islands designed for natural desalination, transforming seawater into usable freshwater over time. As islands multiply outward in layers, they function collectively as wave dissipators and ecological buffers. Interconnected seawalls and tidal gates form a flexible defense spine, designed to accrete vertically in tandem with rising sea levels. The perpetual seeding of biorock, aquaculture, and vegetation transforms the system into a machinic landscape—generating surplus water, food, and construction material for replicable deployment elsewhere. Blurring boundaries between infrastructure and ecology, this territorial strategy redefines coastal resilience as a living, growing, adaptive system rather than a static barrier.
