In December 2005, it was announced that Niger had received 100% multilateral debt relief from the IMF, which translates into the forgiveness of approximately US$86 million in debts to the IMF, excluding the remaining assistance under HIPC. Nearly half of the government's budget is derived from foreign donor resources. Future growth may be sustained by exploitation of oil, gold, coal, and other mineral resources. Uranium prices have recovered somewhat in the last few years. A drought and locust infestation in 2005 led to food shortages for as many as 2.5 million Nigeriens.
