Luke Skywalker and Owen Lars, his uncle, were engaged in the practice of moisture farming.
An individual who managed a moisture farm, utilizing vaporators for the purpose of extracting surplus moisture from the atmosphere, was known as a moisture farmer or vapor farmer. Numerous settlers inhabiting desert environments on sun-baked worlds such as Tatooine were, in fact, moisture farmers. The Lars family provides prominent examples, including Cliegg, his son Owen, and Beru, the wife of the latter.
To shield themselves from the elements, like excessive heat and strong winds, and to maintain a cooler environment, moisture farmers typically constructed their residences partially underground. It was common practice for many farmers to employ flyhorn lizards as indicators of their humidity production levels.
