Urban sprawl in Spain: differences among cities and causes

Urban sprawl has a major impact on the environment, public health and the socio-economic evolution of cities. The causes are numerous, being mainly related to the generalized use of the automobile in modern cities. Urban sprawl has been especially relevant in US cities since the 1950s, rapidly spreading to other cities in the rest of the world. This paper studies the case of Spain using recent data. Spanish cities have grown rapidly over the 90s and 2000s. The country has completed the process of urbanization and has suffered the effects of a major real estate bubble. In this context, we are interested in measuring and explaining where and why urban sprawl has appeared in Spanish cities. Digital mapping carried out around the year 2000 providing full coverage of Spain is used to calculate an Urban Sprawl Index. It is applied to all urban areas and municipalities throughout the country, providing an objective, comparable measurement of sprawl and identifying which areas are most affected by this phenomenon. A second stage of analysis is conducted in an attempt to explain the causes of the differences in sprawl among Spanish cities with a regression model based on the literature. We have found that the cases most affected by sprawl are the latest urban developments on the Mediterranean coast as well as certain areas in the vicinity of large cities: the mountains to the north of Madrid and the coastline near Barcelona and Valencia. In some cases, urban sprawl is starting to become a problem for the environment and urban sustainability, with important consequences for the future evolution of the affected cities.     

Power in Australian foreign policy

The 2017 Foreign Policy White Paper emphasises the importance of ‘maximising’ Australia’s power and influence. However, the White Paper and much of the commentary on Australian foreign policy do not clearly conceptualise ‘power’ or indicate how it ought to be increased. The Lowy Institute’s recent Asia Power Index implies one possible strategy via its resource-based approach to measuring power. We outline a different approach and argue that power should be conceptualised and evaluated as a specific relationship causing behavioural change, rather than as a general attribute of its wielder. To complement the Lowy Institute’s carefully catalogued database, and facilitate a more focused conversation about maximising power and influence in Australian foreign policy, we offer a typology identifying five pathways through which states can translate their material and non-material resources into outcomes that serve the national interest.     

Patterns of pastoralism in later Bronze Age Kazakhstan: new evidence from faunal and lipid residue analyses

Current research themes relating to prehistoric Central Asian pastoralism are discussed, and the Neolithic to Bronze archaeological sequence in Kazakhstan is briefly outlined. The results of new faunal analyses of six later Bronze Age sites in Central and Northern Kazakhstan are presented. These studies are based upon the analysis of 63,529 bone fragments, of which 27,023 were identifiable to species and element. These assemblages are compared with 16 other sites in Central and Northern Kazakhstan, and the Trans-Ural region. The herd structures at the final Bronze Age site of Kent are discussed in detail. Analyses of absorbed lipid residues from four sites are also presented. In total, 140 pottery sherds were analysed, of which 73 provided sufficient residues for stable isotope ratio determinations. It is concluded that species proportions are highly variable regionally. Cattle are most prevalent in the forest steppe zone, whilst caprines become more common in semi-arid steppe regions. Proportions of horse are particularly variable, even within environmentally similar areas. Lipid residue results indicate the high prevalence of ruminant dairy products in pottery vessels, whilst faunal data from Kent suggests that cattle husbandry might have been particularly focussed on milk, in comparison with sheep and goats. The significance of horses within prehistoric pastoralism is discussed.     

ANTHROPOGENIC ENVIRONMENTAL ALTERATION OF THE SEA OF AZOV

The authors concentrate on four aspects of environmental alteration of the Sea of Azov. First, they trace the Azov's problems back to Soviet resource-use conflicts. Second, they present several examples of anthropogenically induced environmental disruption of the Azov's ecosystem. Third, modeling is utilized to project possible future salinity conditions within the Azov. Fourth, in their attempt to evaluate the various ameliorative efforts that have been made or are being proposed, they challenge the overall ecologic-economic effectiveness of the proposed dam across the Kerch' Strait designed to regulate the salinity of the Azov. Finally, they conclude it is unlikely that the Azov ever will be returned to its previous “natural” condition. This article should be read in conjunction with Pecherin's article also in this issue of Soviet Geography. (Illustrations by Elinore Mathews, University of Washington, Seattle.)     

Prologue to Uses of Chemical Residues to Make Statements About Human Activities

Soil chemistry provides the potential for interpreting the archaeological record without necessarily resorting to artifacts, historical documents, ethnoarchaeological observations, or experiments. The range of studies incorporating new technological developments, such as mass spectrometry and multi-element analyses, for analyzing and interpreting the chemical residues found at archaeological sites or modern contexts are increasing in the literature. However, the dilemmas of interpretation concentrate on evaluating the advantages and disadvantages of different techniques. Analytical approaches to how scientists make use of chemical residues to make statements about the past, discussed here, expand the potential of the breadth of techniques to investigate daily life activities and further our understanding of the materiality of social life.
