Interesting article, thanks for that.
Theology has been disastrous for healthcare initiatives in Africa. The Catholic position on contraceptives has meant untold numbers dying horribly from HIV transmission, and Islamic resistance to "western" immunization is one of the obstacles that has forestalled the eradication of Polio in countries like Nigeria. So it's definitely worthwhile pointing out that there are cultural resources inherent to Africa that antedate the arrival of the missionaries, and can be called upon to unite her people.
