reforms, and economic mismanagement. With foreign revenue precariously dependent upon remittances from migrant workers overseas and exports of aluminium and cotton, the economy is highly vulnerable to external shocks. In FY 2000, international assistance remained an essential source of support for rehabilitation programs that reintegrated former civil war combatants into the civilian economy, which helped keep the peace. International assistance also was necessary to address the second year of severe drought that resulted in a continued shortfall of food production. On 21 August 2001, the Red Cross announced that a famine was striking Tajikistan, and called for international aid for Tajikistan and Uzbekistan; however, access to food remains a problem today. In January 2012, 680,152 of the people living in Tajikistan were living with food insecurity. Out of those, 676,852 were at risk of Phase 3 (Acute Food and Livelihoods Crisis) food insecurity, and 3,300 were at risk of Phase 4 (Humanitarian Emergency). Those with the highest risk of food insecurity were living in the remote Murghob District of GBAO. Tajikistan's economy grew substantially after the war. The GDP of Tajikistan expanded at an average rate of 9.6% over the period of 2000–2007 according to the World Bank data. This improved Tajikistan's position among other Central Asian countries (namely Turkmenistan and Uzbekistan), which seem to have degraded economically ever since. The primary sources of income in Tajikistan are aluminium production, cotton growing and remittances from migrant workers. Cotton accounts for 60% of agricultural output, supporting 75% of the rural population, and using 45% of irrigated arable land. The aluminium industry is represented by the state-owned Tajik Aluminum Company – the biggest aluminium plant in Central Asia and one of the biggest in the world. Tajikistan's rivers, such as the Vakhsh and the Panj, have great hydropower potential, and the government has focused on attracting investment for projects for internal use and electricity exports. Tajikistan is home to the Nurek Dam, the second highest dam in the world. Lately, Russia's RAO UES energy giant has been working on the Sangtuda-1 hydroelectric power station (670 MW capacity) commenced operations on 18 January 2008. Other projects at the development stage include Sangtuda-2 by Iran, Zerafshan by the Chinese company SinoHydro, and the Rogun power plant that, at a projected height of , would supersede the Nurek Dam as highest in the world if it is brought to completion. A planned project, CASA-1000, will
