In unirrigated land, [[pasture]] is the most common type of land use. In the rainy season (summer), part of the rangeland is used for cropping (mainly potatoes, barley, broad beans, and wheat).

Irrigation is helpful in advancing the sowing data of the summer crops, which guarantees an early yield in periods of food shortage. Also, by early sowing, maize can be cultivated higher up in the mountains (up to {{cvt|3800|m|||}}). In addition, it makes cropping in the dry season (winter) possible and allows the cultivation of frost-resistant vegetable crops like [[onion]] and [[carrot]].<ref>W. van Immerzeel, 1989.
