Some pupils have come in asking about a possible case study solution for desertification. Desertification can be used for a case study which implies that an ecosystem has been mis-managed or how a high pressure system has affected humans and vegetation.
Desertification is the process of grassland areas turning into desert or arid areas. The Sahel is a region south of the Sahara which can be used as the case study location.
for the causes of desertification check out:

For possible solutions check out: http://www.sln.org.uk/geography/magicstones/Default.htm
This outlines some of the causes and possible solutions (play the EXE files) such as the magic stones.
For more facts about the Sahel just google it eg population figures etc. Make notes off these resources and you'll be fine.

Please check out the presentations at www.soilcarbon.com.au for a genuine way to reverse desertification on a massive scale. Also see http://managingwholes.com/desertification.htm for a different and PROVEN solution.
