Agriculture in Bhutan comprises mainly of cereal crops, among which rice, corn, barley, millet, and wheat form the main crops. Even today, traditional farming methods are practiced and only 3 percent of the land area is cultivated. Besides this, animal husbandry is also practiced, where cattle, yaks, pigs, goats, sheep, and horses most commonly raised.
Bhutan has a large potential for hydroelectric power resources though only a few dams have been built to date; the largest being the Chukha Hydroelectric Project, which is located in Chukha, between Thimphu and Phuntsholing. Opened in 1986, it produces about $25 million in government revenues each year from electricity sold to India. Similar projects are there in the pipeline for the country. Trade and other services, including tourism, employ 5 percent of the workforce. While tourism is Bhutan's largest source of foreign exchange, the country is slightly reluctant to embrace this industry fully. Bhutan's major imports include rice, manufactured goods, fuel, and machinery while major exports include timber; agricultural products such as apples, oranges, and potatoes; handicrafts; spices such as cardamom; precious stones; and electricity. Bhutan's primary trading partner is India even as the country receives imports from Japan, Germany, the United States, and the United Kingdom, and exports goods to Bangladesh, the Middle East, Singapore, and Europe. In the year 2001, Bhutan's GDP was $533 million.
