Agricultural activities contribute to 16% of Mongolian GDP, employs 32% of the labor force and contributes to around 14% of export revenues. However, the contribution to GDP from agriculture has decreased in recent years due to the booming mining industry. Currently, the total area of arable land in the country is estimated at 1,180.8 thousand hectares (2010) of which 290.3 thousand hectares are cultivated, 274.3 thousand hectares are fallow, 186.8 thousand hectares are under rest and 429.4 thousand hectares are abandoned land. Agricultural production focuses on cereals, including wheat, barley, oat, rye, buckwheat as well as oil plants, potatoes and vegetables. With a growing season of only 3 months, high altitudes, extreme fluctuations in temperature, long winters, and low precipitation there are many obstacles that limit the potential for agricultural development.
