According to the Central Bank of Yemen, in 2005 the production of khat, a mildly narcotic and heavily cultivated plant that produces natural stimulants when its leaves are chewed, rose 6.7 percent and accounted for 5.8 percent of GDP; its usage in Yemen is widespread. According to the World Bank and other economists, cultivation of this plant plays a dominant role in Yemen's agricultural economy, constituting 10 percent of GDP and employing an estimated 150,000 persons while consuming an estimated 30 percent of irrigation water and displacing land areas that could otherwise be used for exportable coffee, fruits, and vegetables.Wikipedia
