In some of my research, I read Conflict Management and African Politics by Terrence Lyons and Gilbert M. Khadiagala. This was one of the few books I could find to explore African negotiation. Not all contributions to this book provided a helpful treatment of African negotiations, but there were 3 chapters that made me really glad I read it.
There’s a chapter entitled “Perverse Negotiations” that explores how negotiation approaches can help fight corruption, a theme in the majority world. If you have negotiated in the majority world or dealt with places like government agencies, immigration, or DMV like institutions, you’ll get a kick out of it if you enjoy scholarly assessment of such situations. I used the chapter in my negotiation course and you can find it online here.
There’s a couple of other chapters I found to be really helpful not just for Africa, but for much majority world negotiation. The rest of the chapters explored very specific political realities and especially exploring the failures of Western intervention in Africa over the last thirty years. This is another resource that may not be for everyone, but there were a couple of nuggets of gold I enjoyed.
