Sustainable development and climate change

In 1987, the authors of Our common future argued that unless the world embraced and operationalized sustainable development, it would risk being overwhelmed by a series of interlocking crises related to population growth, urbanization, poverty and environmental degradation. Since then, many authors have argued that the world is on a worst case scenario trajectory. Post‐Rio assessments of progress towards sustainable development have been largely negative. Since 1987, climate change has added a new stressor to the mix while shortening the time frame for transformation. In the context of accelerating change and converging stresses is the concept of sustainable development as compelling today as it was twenty years ago? Is it reasonable to believe there are means by which to reduce poverty and simultaneously protect the environment? This article briefly reviews the global challenges that first stimulated the concept of sustainable development and asks how contemporary processes of global change are affecting both these challenges and this approach to addressing them. While there are some grounds for optimism, several variables are identified that make sustainable development increasingly difficult to design and implement. The article concludes with an evaluation of how these difficulties might be overcome, and why it is essential that we try.     

5. GROSSRAUM AND GEOPOLITICS: RESITUATING SCHMITT IN AN ATLANTIC CONTEXT

Contemporary theorists of international relations and historians of empire have found utility in the spatial theory of “Grossraum,” or “great space,” that Carl Schmitt developed in the 1930s and 40s. This article asks whether Schmitt's concept of Grossraum can be fully disentangled from its German history—from the Nazi pursuit of Lebensraum in which it eventually culminated, but with which it is not identical either. I argue that Schmitt's Grossraum theory is neither merely a symptomatic reflection of the Third Reich's objectives, nor a free‐floating theory with strong potential for critiquing imperialism, but is best approached as an important moment in the transatlantic conversation among empires that unfolded between 1890 and 1945 about the sources, methods, and prerogatives of global power. It compares Schmitt with other figures in German geopolitics such as Friedrich Ratzel and Karl Haushofer in order to establish a genealogy of the distinction between land and sea powers, arguing that Schmitt's writings on Grossraum modernize and transmit to the twentieth century the most influential theories of political geography and geopolitics developed in the Atlantic world between 1890 and 1930.     

THE ROMAN DENARIUS UNDER THE JULIO-CLAUDIAN EMPERORS: MINTS, METALLURGY AND TECHNOLOGY

Summary. The results of the chemical analysis of 78 silver denarii issued by the Julio-Claudian emperors are presented and interpreted against the available numismatic, archaeological and historical information. Earlier surface analyses are found to be incorrect, especially for the coinage of Nero, and the reasons for this are investigated. The new elemental data are augmented by a subset of coins being subjected to lead isotope analysis and the results of this are found to complement these data in unexpected ways.
