copper deposits rank tenth in the world and its uranium deposits twelfth. The country's uranium production ranks seventh globally. The Uzbek national gas company, Uzbekneftegas, ranks 11th in the world in natural gas production with an annual output of . The country has significant untapped reserves of oil and gas: there are 194 deposits of hydrocarbons in Uzbekistan, including 98 condensate and natural gas deposits and 96 gas condensate deposits. Uzbekistan improved marginally in the 2020 Ease of Doing Business ranking by the World Bank. The largest corporations involved in Uzbekistan's energy sector are the China National Petroleum Corporation (CNPC), Petronas, the Korea National Oil Corporation, Gazprom, Lukoil, and Uzbekneftegas. Along with many Commonwealth of Independent States or CIS economies, Uzbekistan's economy declined during the first years of transition and then recovered after 1995, as the cumulative effect of policy reforms began to be felt. It has shown robust growth, rising by 4% per year between 1998 and 2003 and accelerating thereafter to 7%–8% per year. According to IMF estimates, the GDP in 2008 will be almost double its value in 1995 (in constant prices). Since 2003 annual inflation rates varied, reaching almost 40% in 2010 and less than 20% in 2019. Uzbekistan has GNI per capita of US$2,020 in current dollars in 2018, giving a PPP equivalent of US$7,230. Economic production is concentrated in commodities. In 2011, Uzbekistan was the world's seventh-largest producer and fifth-largest exporter of cotton as well as the seventh-largest world producer of gold. It is also a regionally significant producer of natural gas, coal, copper, oil, silver and uranium. Agriculture employs 27% of Uzbekistan's labour force and contributes 17.4% of its GDP (2012 data). Cultivable land is 4.4 million hectares, or about 10% of Uzbekistan's total area. While official unemployment is very low, underemployment – especially in rural areas – is estimated to be at least 20%. Cotton production in Uzbekistan is important to the national economy of the country. Uzbek cotton is even used to make banknotes in South Korea. The country has a considerable production of carrots as well. The use of child labour in Uzbekistan has led several companies, including Tesco, C&A, Marks & Spencer, Gap, and H&M, to boycott Uzbek cotton. Facing a multitude of economic challenges upon acquiring independence, the government adopted an evolutionary reform strategy, with an emphasis on state control, reduction of imports and self-sufficiency in energy.
