This interdisciplinary study of the disruptions threatening aquatic systems in Africa provides a continent-wide perspective on multidimensional environmental problems in the context of a rapidly expanding human population. Contributors confront both local and international water resource issues in Africa, illustrate commonalities among countries, and examine varied approaches used to solve water resource management problems. Linking social and natural sciences in diverse environmental and social settings at different scales of analysis (historical, regional, and ecosystem), the contributors identify regional issues and detect generalities to provide a baseline for decision making in the 21st century.
