The World Bank and the International Monetary Fund, as primary holders of developing countries' debt, attach structural adjustment conditionalities in return for loans which are generally geared toward loan repayment with austerity measures such as the elimination of state subsidies and the privatization of state services. For example, the World Bank presses poor nations to eliminate subsidies for fertilizer even while many farmers cannot afford them at market prices. In Malawi, almost five million of its 13 million people used to need emergency food aid but after the government changed policy and subsidies for fertilizer and seed were introduced, farmers produced record-breaking corn harvests in 2006 and 2007 as Malawi became a major food exporter. A major proportion of aid from donor nations is tied, mandating that a receiving nation spend on products and expertise originating only from the donor country. US law requires food aid be spent on buying food at home, instead of where the hungry live, and, as a result, half of what is spent is used on transport.
