You might try:
Scoones, I., et al., 1996,
Hazards and Opportunities: Farming Livelihoods in Dryland
Africa - Lessons from Zimbabwe,
London and New Jersey: Zed Books
It goes into detail about the different ways in which
rural people in Zimbabwe coped with the disastrous droughts
in 1991 and '92. (By "systems" I'm hoping you mean human
communities, too.)

:}I am trying to research the differences in systems that are diverse
:}biologically and structurally compared to monocultures in the face of
:}climate change. If anyone has any ideas or sources I would really
:}appreciate the input.
:}I am largely concerned with forest systems but general issues or case
:}studies would be helpful.
:}As a means of future management for resources it seems that illustrating
:}the importance of diversity and variety is a fundamental issue. I hope to
:}be able to compile some coherent argument for this.
