Xenoagriculture

The practice of cultivating and farming alien or genetically modified organisms for food, materials, or ecosystem services on off-world colonies. This isn't just planting Earth seeds in Martian dirt; it's a total re-engineering of agriculture. It involves creating soil analogs from regolith, engineering plants to thrive under alien sunlight (or artificial light), using closed-loop aquaponics with local water, and potentially domesticating or hybridizing hardy native flora. The goal is to create a sustainable, in-situ food web that reduces reliance on costly Earth imports.

Example: In Kim Stanley Robinson's Mars trilogy, Xenoagriculture involves genetically engineering Earth crops to tolerate perchlorates in Martian soil, creating lichen to begin terraforming, and later developing entirely new agricultural systems in pressurized domes. It's farming where every variable—gravity, day length, soil chemistry—is a problem to be solved.
