Sea level rises pose a greater long term threat to Australia's coastline and major capital cities than a military attack by a foreign power. Citizens are more likely to experience a pandemic virus than a nuclear threat. Food shortages have already occurred as a result of flood or drought, and the tentacles of international trade in drugs, money laundering and human trafficking already reach far into Australian communities.Why Human Security Matters argues that Australian external relations needs to treat the 'soft' issues of security as seriously as it treats the 'hard' realities of military defence, but also the many complex situations in-between, whether it be civil war, political upheaval, terrorism or piracy. Australia needs to do this first and foremost in our region, but also in relation to the unresolved regional and global security issues as we confront an increasingly uncertain and turbulent world.With contributions from leading thinkers in foreign policy and strategic studies, Why Human Security Matters is essential reading for anyone seeking a thoughtful and thought-provoking analysis of Australia's place in an age of transition.
