Uganda’s eagerness for genuine development is reflected in its schoolchildren’s smiles and in the fact that so many children are now going to school. Since 1997, when the government began to provide universal primary education, total primary enrollment had risen from 3 million to 7.6 million in 2004. Schools have opened where none existed before, although there is some way to go in reaching the poorest areas of the country. Uganda has also made strides in secondary and higher education, to the point that it is attracting many students from other countries. At the secondary level, enrollment is above 700,000, with the private sector providing the majority of schools. For those who want to take their education further, there are 12 private universities in addition to the four publicly funded institutions, together providing 75,000 places. Education is seen as a vital component in the fight against poverty. The battle for better health is another, although it is one that will take longer to win in a country that carries a high burden of disease, including malaria and AIDS. Here, the solutions can only arise from a combination of international support and government determination to continue spending public money on preventive care and better public health information. Current government plans include recruiting thousands of nurses, increasing the availability of drugs and building 200 new maternity units. Uganda’s high rate of population growth, at 3.6 percent per annum, poses a special challenge in the fight against poverty, says Finance Minister Gerald Ssendaula, who points out that the fertility rate, at 6.9 children per female, is the highest in Africa. The government’s newly revised Poverty Eradication Action Plan (PEAP) puts the "restoration of security" at the top of the current government agenda. This is because it estimates that Uganda has lost 3 percent of its gross domestic product each year that the conflict has persisted. Displaced people are not only a financial burden, they are unable to contribute to the economy. The other core challenges identified by the revised PEAP are finding ways to keep the lowest income growing, improving the quality of education, giving people more control over the size of their families and using public resources transparently and efficiently. It is a document that other poor countries could learn from.
