Economic development, population growth and poor resource management have combined to alter the planet?s natural environment in dramatic and alarming ways. For over twenty years, considerable research and debate have focused on clarifying or disputing linkages between various forms of environmental change and various understandings of security. At one extreme lie sceptics who contend that the linkages are weak or even non-existent; they are simply attempts to harness the resources of the security arena to an environmental agenda. At the other extreme lie those who believe that these linkages may be the most important drivers of security in the 21st century; indeed, the very future of humankind may be at stake.
