Population and Environment...

Option 1: 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 when population growth is a recipe for disaster, and when it acts as a catalyst for economic and environmental enhancement.

Option 2: 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.

Option 3: Rethinking methodologies - using oral history, remote sensing and participatory observation in longer-term time series studies of environmental change, with sepcial reference to biases in data collection and 'cleaning' arising from differences in indigenous and foreign perceptions.


Note: This subject combination is particularly suitable for debates and participatory workshops.
