Agriculture in Iryna is highly reliant on external food sources, due to the island's extremely small size relative to its population. The smaller islands of the Corvidan Archipelago have traditionally exported up to 80% of their annual yield to Irynian markets, but even this contribution is not enough to sustain the Irynian population alone. In the modern era, an increasing percentage of the food consumed by Irynians is grown on greenhouse galleys and in offshore aquaculture facilities. Even with the many innovations created by Irynians to combat their agricultural deficiencies, some compromises have been unavoidable. Crops that could not readily be grown in small spaces were abandoned in favor of reliable year-round producers, and the production of meat was restricted to ensure a healthy population of livestock for other animal source foods. To diversify their diets, some Irynians cultivate gardens on rooftops, balconies, or countertops. Arcane researchers have attempted to create synthetic food that would require no farming space at all, but those efforts proved too labor-intensive to be sustainable long-term.
The typical Irynian diet consists of seafood, root vegetables, fruits and nuts. Common beverages include tea, fruit juice, and sugarcane juice. Some staple ingredients are:
