Survey of Sub-Saharan Africa is the most comprehensive and up-to-date text available on African geography. It features both systematic chapters (looking thematically at Sub-Saharan Africa as a whole) followed by regional chapters (usually covering individual countries). The systematic chapters are organized to cover the geography of human origins, changing language patterns, historical/political geography, urbanization/development, the diffusion of AIDS, and agriculture. Throughout the text, the authors embrace the diversity of theoretical interpretations of African geography, helping students interpret data and join the debates.
