Endowed with significant natural resources, including ample fertile land, regular rainfall, and mineral deposits, it is thought that Uganda could feed all of Africa if it were commercially farmed. The economy of Uganda has great potential, and it appeared poised for rapid economic growth and development.gricultural products supply nearly all of Uganda's foreign exchange earnings, with coffee alone (of which Uganda is Africa's leading producer) accounting for about 27% of the country's exports in 2002.
Rwanda has a small industrial sector that only employs about 3% of the population. Other than agricultural processing, there is also a brewery. The industrial sector was hard hit by the recent turmoil and has just begun to recover. The Rwandan economy was completely devastated by war in 1990-1994. The present government is trying to help the economy recover by adopting a neo-liberal approach [1]. This includes trying to increase the revenue from exports of coffee and tea by privatizing large sectors of this government run industry.
