Nearly 47% of Tajikistan's GDP comes from immigrant remittances (mostly from Tajiks working in Russia). The current economic situation remains fragile, largely owing to corruption, uneven economic 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 August 21, 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.
