Education experts say Africa’s growing higher education system is important to its economic development. [5]But African universities face a number of issues, including emigration of top students, poor facilities, and high demand combined with a lack of funds.
    University leaders from around the African continent met in Johannesburg last week to discuss how to solve these issues and others. The academics who attended the African Universities Summit say the job of educating Africa’s students is harder than it has to be.
    Engineering professor David Mfinanga is a vice chancellor at the University of Dares Salaam in Tanzania. He says the main problem facing universities is the high number of students. "But the resources are limited. You need the quantity, you need more graduates, but you need to maintain the quality, and the resources are limited."
    There are no simple answers to the issues that African universities face. But, African educators say the issues are just as serious as many of the continent’s other difficult problems, such as war, famine, poverty and quickly changing leaders. And in this case, they say, solving higher education’s problems may help solve the others.
