Abstract

This paper explores the relationships between climate change and security. Potential threats from climate change, as a unique source of stress or together with other factors, to human security are first examined. Some of the most explicit examples illustrate this section : food security, water availability, vulnerability to extreme events and vulnerability of small islands States and coastal zones. By questioning the basic needs of some populations or at least aggravating their precariousness, such risks to human security could also raise global security concerns, which we examine in turn, along four directions : rural exodus with an impoverishment of displaced populations, local conflicts for the use of natural resources, diplomatic tensions and international conflicts, and propagation to initially-unaffected regions through migratory flows.
