Climate change, conflict and development in Sudan: global neo-Malthusian narratives and local power struggles

Dystopian accounts of climate change posit that it will lead to more conflict, causing state failure and mass population movements. Yet these narratives are both theoretically and empirically problematic: the conflict–environment hypothesis merges a global securitization agenda with local manipulations of Northern fears about the state of planetary ecology. Sudan has experienced how damaging this fusion of wishful thinking, power politics and top-down development can be. In the 1970s, global resource scarcity concerns were used locally to impose the fata morgana of Sudan as an Arab-African breadbasket: in the name of development, violent evictions of local communities contributed to Sudan's second civil war and associated famines. Today, Darfur has been labelled ‘the world's first climate change conflict’, masking the long-term political-economic dynamics and Sudanese agency underpinning the crisis. Simultaneously, the global food crisis is instrumentalized to launch a dam programme and agricultural revival that claim to be African answers to resource scarcity. The winners, however, are Sudan's globalized Islamist elites and foreign investors, whilst the livelihoods of local communities are undermined. Important links exist between climatic developments and security, but global Malthusian narratives about state failure and conflict are dangerously susceptible to manipulations by national elites; the practical outcomes decrease rather than increase human security. In the climate change era, the breakdown of institutions and associated violence is often not an unfortunate failure of the old system due to environmental shock, but a strategy of elites in wider processes of power and wealth accumulation and contestation.     

Space–Time Accessibility Under Conditions of Uncertain Travel Times: Theory and Numerical Simulations

Recently, several accessibility measures using the space–time prism concept have been suggested in the literature. These measures fail to take into account (i) the ability of individuals to adjust their activity–travel patterns in coping with constrained choice sets, (ii) uncertainty in the perception of travel times, (iii) temporal variability of travel times, and (iv) the influence of travel information on accessibility. The aim of the present article is to contribute to this literature by addressing these four shortcomings. Theory will be developed and illustrated using numerical simulations. The results suggest that the accessibility measure proposed in this article is a useful indicator of social inclusion in terms of the time individuals can spend to conduct their preferred activities. Moreover, accessibility is found to be affected by the presence of schedule delay penalties, restrictions in time allocation to activities, and the provision of travel time information in order to reduce uncertainty.     

Hunter-gatherer burials and the creation of persistent places in southeastern Australia

One of the difficulties in interpreting hunter-gatherer mortuary practices is that many mortuary theories are derived from sedentary societies and rely upon an excavated record. This paper is an analysis of both historical and archaeological evidence of Aboriginal burial practices in the Murray River region of southeastern Australia. The archaeological data relies primarily upon analysis of burials exposed through erosion rather than systematic excavations which limits the range of burial characteristics that may be recorded and interpreted. The mortuary practices identified are highly patterned but regionally and locally variable. It is argued that the evidence demonstrates the persistence of place for Aboriginal people. The existence of persistent places is further related to a potentially fluid but structured connection between people and land.     

Obscure oases: natural,cultural and historical geography of western Queensland's Tertiary sandstone springs

The distribution of surface water dictates human and animal activity in arid zones. Although typically small, hidden, and inaccessible, springs and wells fed by local aquifers were the only sources of reliable water across vast areas of inland Australia until the last century. Compared to larger, more accessible water sources such as riverine waterholes and Great Artesian Basin discharge springs, their history is sketchy and poorly documented, although rich in intrigue and mythology. Since the expansion of artificial waters and motorised transport, many of these small oases have been forgotten, and their location and permanence are now less well‐known than for thousands of years. We examine the distribution, hydrogeology, cultural history, and biological values of Tertiary sandstone springs in western Queensland based on a review of historical literature, interviews with long‐term residents, and extensive field surveys. One hundred and sixty springs were documented, and nearly 40% of these have declined in flow or become inactive since pastoral settlement for reasons that are not well understood. While their decline in some areas seems related to shallow bores sunk into their local aquifers, it is possible that some smaller springs owed their existence to regular human maintenance. Others are probably naturally dynamic over decadal time scales. This study documents an almost‐forgotten aspect of Queensland's natural and cultural history.     

Report on the Progress of the Excavations at Wroxeter,the Roman Urioconium

An evaluation exercise, involving geophysical survey and limited excavation, was undertaken on a site where aerial photography indicated the presence of a number of substantial timber buildings. The work demonstrated that the site was of the early medieval period and that the buildings possessed structural characteristics comparable to those found on other excavated high status sites of the sixth to seventh centuries. Following the evaluation exercise the site was designated as a monument of national importance (Wilts 917).

Carbon and nitrogen isotope signals in eel bone collagen from Mesolithic and Neolithic sites in northern Europe

Carbon and nitrogen isotope analysis was undertaken on collagen extracted from eel bone from six Mesolithic and Neolithic sites in northern Europe. The results were compared with data obtained on other archaeological fish remains and modern eel caught in fresh and brackish water and from the sea. The possibility of discriminating between freshwater, brackish and marine signals in archaeological eel bone is evaluated and the implications for archaeology discussed. Our data suggest that eel found at coastal Mesolithic and Neolithic sites have carbon isotope signals consistent with a marine origin with no evidence of freshwater residency. The sample of eel bone from one inland site is small but indicates carbon isotope values more consistent with freshwater residency or at least values intermediate between freshwater and marine carbon pools.
