Well, I suggest you find out which organisms are in place in these countries that can tell you what is the status of their efforts and then try to respond to their needs. The UNESCO has offices all over the world and in every single country in Africa. In my humble opinion they are the one that assess in the most objective manner the needs. Contacting them and working with some of their programs would be a start. OR You can get from them information about local NGOs and attempt to contact them directly. Have a nice evening
