Tourism is also an important part of the economy. Primarily an agricultural and pastoral economy, Rajasthan have good mineral resources. It has rich salt deposits at Sambhar and elsewhere and copper mines at Khetri and Dariba. The white marble is mined at Markana near Jodhpur. The main industries are textiles, the manufacture of rugs and woolen goods, vegetable oils and dyes.
Heavy industries includes the construction of railway rolling stock, copper and zinc smelting.
The chemical industry also produces caustic soda, calcium carbide and sulphuric acid, fertiliser, pesticides and insecticides. The principal industrial complexes are at Jaipur, Kota, Udaipur and Bhilwara. Having much arid land, Rajasthan needs extensive irrigation. The Rajasthan Canal, renamed the Indira Gandhi Canal in the mid-1980s for the late prime minister, carries water from the Beas and Sutlej rivers in Punjab some 400 miles to irrigate desert land in northwestern and western Rajasthan. Electricity supplies are obtained from neighbouring states and from the Chambal Valley project.
