The limits of engagement: British foreign policy and the crisis in Zimbabwe

This article examines how the British government has responded to Zimbabwe’s ongoing crisis. This case raises several wider issues for British foreign policy, most notably the question of how much leverage London can exercise on the international scene in general, and over relatively small and weak states like Zimbabwe in particular. Zimbabwe’s crisis also raises profound questions about the appropriate balance between bilateral and multilateral policies, and between engaging in public criticism and conducting so–called ‘quiet diplomacy’. While bilateralism clearly has not worked, multilateralism has revealed its own frustrations, especially given the reluctance of many African elites within a number of organizations to criticize President Mugabe’s policies. This reluctance threatens to unravel the British Labour government’s stated objectives in Africa while at the same time raising important doubts over the credibility of the New Partnership for Africa’s Development (NEPAD), and whether an ‘Africa moment’ can be discerned in the manner articulated by prime minister Tony Blair.     

“The apple of my eye”: Carl Sauer and historical geography

Many historical geographers would claim Sauer to be one of them. Yet, with the exception of his Foreword to historical geography (1941) he made no major declaration of his interest in the sub-discipline. This paper attempts to examine Sauer's attitude to the time element in geography through a close appraisal of his published work but particularly through his hitherto unpublished correspondence. It soon becomes evident that Sauer changed his ideas during his long working life, and that it is difficult to disentangle Sauer's philosophy about the time element in geography from his philosophy about life, particularly within university circles in the United States, and within American society in general. Sauer's comment to a student in 1936 that historical geography “is of course the apple of my eye” would seem to be demonstrated amply, but that historical geography was not a conventional methodology so much as a flexible metaphor to encompass the study of man on earth through time. It was also the vehicle for some of his prime concerns; scholarship, independent thought, opposition to bureaucracy, concern for human values and environmental quality, and deep distaste for the technological and scientific “fix”, particularly the solutions offered by the social sciences. It might repay contemporary historical geographers to take a close look at Sauer's academic and intellectual values.     

Participation and Power: Poor People's Engagement with India's Employment Assurance Scheme

‘Participation’ has become an essential part of good developmental practice for Southern governments, NGOs and international agencies alike. In this article we reflect critically on this shift by investigating how a ‘participatory’ development programme — India's Employment Assurance Scheme (EAS) — intersects with poor people's existing social networks. By placing the formalized process of participation in the EAS within the context of these varied and uneven village–level relationships, we raise a number of important issues for participatory development practice. We note the importance of local power brokers and the heterogeneity of ‘grassroots’ (dis)empowerment, and question ideas of power reversals used within the participatory development literature.     

Introducing δSr analysis in archaeology: a demonstration of the utility of strontium isotope fractionation in paleodietary studies

Isotopic methods are widely used in archaeology to investigate paleodiet. Here, we present a new method to identify trophic level in archaeological human populations and to investigate paleodiet. We demonstrate that strontium isotope compositions (reported as δ^88/86Sr) vary in a mass-dependent manner with increasing trophic level and can elucidate paleodiet in archaeological human populations. We present new mass-dependent strontium isotope data from tooth enamel and bone from individuals buried during the Late Intermediate Period (c. AD 1000–1300) in the large cemeteries of Chiribaya Alta, Chiribaya Baja, San Gerónimo, and El Yaral in the Ilo and Moquegua Valleys of southern Peru. We compare these data to radiogenic strontium isotope data (⁸⁷Sr/⁸⁶Sr) and light stable isotope data (δ¹⁵N_col and δ¹³C_col) from the same individuals to investigate geologic variability in strontium sources as well as marine food consumption among the Chiribaya. Our results demonstrate the utility of measurements of strontium isotope fractionation as a new tool for archaeological investigation of paleodiet. Importantly, this new technique can be used to generate paleodietary (δ^88/86Sr) and paleomobility (⁸⁷Sr/⁸⁶Sr) data from the same specimen, minimizing destructive analyses of invaluable archaeological material, and provides a new way to examine paleodiet through hydroxyapatite, which is particularly important when collagen is poorly preserved.     

In situ oxygen isotope micro-analysis of faunal material and human teeth using a SHRIMP II: a new tool for palaeo-ecology and archaeology

A Sensitive High Resolution Ion MicroProbe (SHRIMP II) has been used to make high spatial resolution in situ micro-analyses of oxygen isotopes in fish otoliths, and teeth from fossil herbivores and a Neanderthal. Large intra-tooth variations in the oxygen isotopic composition (up to 9‰) were observed in the enamel of herbivores from the Neanderthal fossil site of Payre, consistent with preservation of seasonal cyclicity. The range of isotopic compositions observed in Neanderthal tooth enamel was much smaller (∼3‰), possibly the result of a longer enamel maturation time averaging out variability. An archaeological otolith from a Preceramic site in Northern Peru exhibited marked changes in δ¹⁸O over life, due either to the fish occasionally migrating from the sea to a lower salinity habitat, or to short-lived rises in sea water temperature. A fish otolith from Australia's Willandra Lakes World Heritage Area showed clear seasonal variations, but also a general trend towards isotopically heavier and more saline water, as indicated by higher δ¹⁸O and Sr/Ca values resulting from increased evaporation. The results of these case studies are compared to results of oxygen isotope analysis using more conventional methods and demonstrate the ability of the SHRIMP II to provide precise high spatial resolution in-situ oxygen isotope analyses of a variety of biogenic materials. This approach has major advantages over conventional methods. It can provide rapid, micro-scale isotopic analyses of sub-permil precision without the need for chemical preparation of the sample.
