Climate change presents humanity with its largest challenge in recorded history. Its predicted eff ects over the coming decades include extreme weather events, droughts, fl ooding, rising sea levels that could affect countries such as Nigeria and Mozambique, retreating glaciers (although not in Africa, but with global impact), changes in habitats and increased spread of life-threatening diseases such as malaria.

Little concrete analysis has been published on the relationship between climate change and conflict, however, and even less on the potential role that population growth plays in intensifying that pressure.
