Agriculture is an important sector of the economy in Kyrgyzstan (see agriculture in Kyrgyzstan). By the early 1990s, the private agricultural sector provided between one-third and one-half of some harvests. In 2002, agriculture accounted for 35.6% of GDP and about half of employment. Kyrgyzstan's terrain is mountainous, which accommodates livestock raising, the largest agricultural activity, so the resulting wool, meat and dairy products are major commodities. Main crops include wheat, sugar beets, potatoes, cotton, tobacco, vegetables, and fruit. As the prices of imported agrichemicals and petroleum are so high, much farming is being done by hand and by horse, as it was generations ago. Agricultural processing is a key component of the industrial economy as well as one of the most attractive sectors for foreign investment.
