Hi there! Welcome to the SMNetwork :-)
Out of curiosity, why Africa? And where in Africa appeals to you? Have you looked into cities/countries/regions that suit your interests and goals? What/where are they?
A friend of mine spent a year in Ghana, using theater and acting techniques to do community-building exercises in a handful of villages. Granted, he went through an English-based Study Abroad program. Would this kind of teaching-oriented experience appeal to you? I would be happy to write him a note on your behalf.
I recently worked on a production that had a strongly international cast, many of whom are from Africa and have worked in the theater/dance world internationally. PM me if you're interested in chatting about specifics!
