I want to take just a minute to promote my friend Mark Nyandoro's new book on Zimbabwe. Mark is a Zimbabwean currently living in South Africa where he is an academic on a fellowship at the University of the North West. Development and Differentiation: The Case of TILDOR/ARDA Irrigation Activities in Sanyata (Zimbabwe), 1939-2000 is an important contribution to the literature on water management and the confluence of environmental history and politics in not only Zimbabwe but southern Africa. It may be priced out of the range of most casual readers, but please recommend it to your local university library.
