Minecraft wiki entry for Survival_in_an_infinite_desert, associated text: As of Village & Pillage, desert village farm can also grow melon stem, which can be useful for melons as food, as villagers are unable to harvest and replant melons, but melon stem can grow infinitely. Cats and even farm animals also spawn in desert villages. Farm animals in village pens usually only spawn in pairs, so be sure to always breed more animals than you slaughter.
