A century on the edge: from Cold War to hot world, 1945–2045

The article argues that the century from 1945 is likely to prove seminal in terms of human progress. It marks the period when the human community has to come to terms with its capacity for self‐destruction through the invention of weapons of mass destruction and its ability to exceed the homeostatic capabilities of the global ecosystem in an era of deep socio‐economic divisions. Two‐thirds of the way through this century the progress has been mixed. Nuclear war has been avoided more by luck than by wisdom, there remain risks of nuclear proliferation and it is not evident that humankind has acquired the ability to deal with the destructive potential of bio‐, nano‐ and other emerging technologies. Recognition of the extent of anthropogenic impacts on ecosystem stability is evident, but not at the level necessary for the radical responses required. Even so, there are signs of progress and potential for change, suggesting that the final one‐third of the century will be singularly important in ensuring long‐term emancipation and environmental sustainability.     

REIMAGINING ROMAN PORTS AND HARBOURS: THE PORT OF ROMAN LONDON AND WATERFRONT ARCHAEOLOGY

This paper explores some theoretically informed ways in which to use the rich evidence relating to ports, harbours and other waterfront installations in archaeology. It argues that studies of waterfront structures within the specialisms of nautical/maritime and wetland archaeology are extremely important in their own right, but they could also be used to explore broader issues connected with their use and context. These include the cultural and religious significance of water and its dangers, the symbolic significance of landscape change, the relationship between people and their environment and the negotiation of the land/water interface. Examining the evidence of the port of Roman London as a case study, this paper explores the archaeology in its local setting and addresses a number of subjects relating to both its temporal and spatial position. It focuses on the religious significance of water and the implications of altering waterscapes through artificial construction.
