Do you know ArXiv, the open pre-print database of scientific articles?
Well, there's also https://info.africarxiv.org/ for African research:
AfricArxiv is a free, open source and community-led digital archive for African research. We provide a non-profit platform for African scietists to upload their working papers, pre-prints, accepted manuscripts (post-prints), and published papers. We also provide options to link data and code, and for article versioning.

Look into that, not just the Black Panther :P
