The Impact of Urbanisation on the Bed Sediments of South Creek,New South Wales

The textural and geochemical characteristics of the bed sediments in South Creek are examined. The bed substratum in the urbanised reaches differs from that of the rural reaches, in terms of the volume and size of the fine matrix sediment and the concentration of heavy metals. The impact of urbanisation on the river-bed sediment is variable, with less matrix than ‘expected’ within the substratum of the urban reach and more than ‘expected’ in the below urban reach. The urban matrix sediment is also significantly finer in comparison to the rural reach matrix sediment. Heavy metal concentrations within the urbanised matrix sediment are up to 800 times greater than background levels and are considered to be indicative of extreme contamination despite only SO years of urbanisation.     

Human security: a new strategic narrative for Europe

This article examines the potential of human security as a narrative and operational frame for the European Union's external relations. Human security is about the security of individuals and communities and it links physical and material security—‘freedom from fear’, and ‘freedom from want’. The article addresses both the lexis (language) and praxis (practice)of human security in relation to the EU. Much of the language currently used in EU external relations, particularly crisis management, civil—military cooperation and conflict management, already contains elements of a human security approach. At the same time, the concept of human security goes beyond these terms and if formally adopted and elaborated could greatly strengthen the EU's role as a global security actor. The article develops five principles of human security—human rights, legitimate political authority, multilateralism and regional focus—and makes the case that the application of these principles would increase the coherence, effectiveness and visibility of EU missions. The article concludes that the adoption of a human security approach would build on the foundational ideas of Europe in overcominga history of war and imperialism and could help to rally public opinion behind the European idea. More importantly, it would contribute to closing the real security vacuum that exists in large parts of the world today.
