One of the poorest countries in the world, Guinea-Bissau's legal economy depends mainly on farming and fishing, but trafficking narcotics is probably the most lucrative trade. Cashew crops have increased remarkably in recent years. Guinea-Bissau exports fish and seafood along with small amounts of peanuts, palm kernels, and timber. Rice is the major crop and staple food. However, intermittent fighting between Senegalese-backed government troops and a military junta destroyed much of the country's infrastructure and caused widespread damage to the economy in 1998; the civil war led to a 28% drop in GDP that year, with partial recovery in 1999-2002. In December 2003, the World Bank, IMF, and UNDP were forced to step in to provide emergency budgetary support in the amount of $107 million for 2004, representing over 80% of the total national budget. The combination of limited economic prospects, a weak and faction-ridden government, and favorable geography have made this West African country a way station for drugs bound for Europe.
