Africa's Growing Population, Environment and Economy. Using first-hand, time series case studies from Africa's main
ecological zones, popular assumptions are challenged by examining

Re-thinking basic criteria - concepts of AEZ, critical carrying capacity, threshold density, biological optima,
economic optima, soil fertility, fragility and resilience, with
special reference to the changing Sahara and Sahel.
