A volume is being prepared, under the over-all guidance and editorship of Gottfried O. Lang and Peter F. M. McLoughlin, on progress among the Sukuma, Tanzania's largest tribal group. The book is both historical and interdisciplinary, covering aspects of geography, economics, agricultural economics, anthropology, political science, sociology, and history. Occupying some 20,000 square miles east and south of Lake Victoria, the Sukuma own approximately one-fifth of Tanzania's livestock and produce most of the country's cotton, the second largest export by value. Chapters will pay particular attention to the factors which have been responsible for Sukumaland's positive economic, social, and political changes, as well as to those elements which have precluded or delayed change. The orientation is practical; development experience will be analysed so that current and future policies and procedures may profit from a more precise definition of trends, problems, and prospects. An appendix will synthesise contributors, research methodologies, techniques, and problems.
