Agriculture is a small part of the economy which contributes only 6% of the GDP of Azerbaijan but employs 38.3% of the workforce. 21.78% of the total land area is arable land (land where crops can be cultivated (grown)) and 2.1% are used for permanent crops (crops which last for many seasons, rather than being replanted after each harvest). 16.45% of the total land area, which makes up the majority of Azerbaijan's cultivated lands, is irrigated. The major crops for are agricultural cash crops, grapes,cotton, tobacco, citrus fruits, rice, tea and vegetables. Livestock, dairy products, and wine and spirits are also important farm products. Farms in Azerbaijan are organized as state and cooperative farms which employ many farmers, and small private farms which are owned and run by one farmer and his/her family. A leading caviar producer and exporter in the past, Azerbaijan's fishing industry today is concentrated on the dwindling supply of sturgeon and beluga in the Caspian Sea.
