From the Sands of the Ogaden to Black Hawk Down: The End of the Cold War in the Horn of Africa

From the Ogaden War to the Black Hawk Down incident, the Horn of Africa was a theatre of events with far-reaching international consequences. This paper argues that the distinctive process leading to the end of the bipolar conflict in the Horn is crucial to understanding the role of this region both during and after the Cold War. Through an extensive analysis of the period 1985–1991, this article explains why only a few years after the ‘burial’ of SALT II in the sands of the Ogaden, the superpowers withdrew from the region which had been the symbol of the failure of détente. Similarly, an analysis of the end of the Cold War is paramount to understanding why, after the break-up of the USSR, the Horn of Africa hosted one of the most tragic episodes of post-Cold War US foreign policy.     

Animal Disease Challenges to the Emergence of Pastoralism in Sub-Saharan Africa

Despite the antiquity of domestic cattle in the Sahara-Sahel, archaeological evidence from two sub-Saharan regions indicates that the first pastoralist colonization of sub-Saharan Africa may not have proceeded so smoothly as modern appearances suggest. The first appearance of cattle-based economies seems to have been delayed by as much as a thousand years after the first appearance of small stock, in both eastern and southern Africa. This article reviews the relevant archaeological evidence and argues that the lag in successful introduction of cattle stems from new animal diseases encountered by pastoral colonists entering biogeographic zones south of the Sahel. Diseases that are often fatal to cattle, including wildebeest-derived malignant catarrhal fever (WD-MCF), East Coast fever (ECF), foot-and-mouth disease (FMD), and Rift Valley fever (RVF), as well as trypanosomiasis, are described as probable barriers to the early entry of cattle-based economies into these regions.Malgré l'antiquité des animaux domestiques dans le Sahara-Sahel, les données archéologique de deux régions subsahariennes indiquent que les premières colonisations pastoraux des zones au sud du Sahel ne se propagèrent pas aussi promptement que suggèrent les apparences actuelles. En l'Afrique orientale et en l'Afrique du sud, l'apparition d'économies basées sur l'élevage des gros bovins paraît être retardée de quelque mille ans par rapport à l'apparition des petits ruminants domestiques dans ces mêmes régions. L'article recense les données archéologiques pertinentes et propose que le délai de l'introduction effective des gros bovins fût causée par des nouvelles maladies vétérinaires rencontrées par les premiers colonisateurs pastoraux entrant dans les zones biogéographiques au sud du Sahel. Des maladies fréquemment fatales aux gros bovins, telle que le coryza gangreneux, la thèleriose, la fièvre aphteuse, l'arbovirus des Bunyaviridae, aussi bien que la trypanosomiase, sont proposées comme des obstacles probables à la diffusion des économies à gros bovins dans ces régions.     

英国的环境史研究

英国的环境史研究的起源与美国不同,它是英国深厚的环境研究基础和英帝国多元学术文化交流相结合的产物。在英国的环境史研究发展进程中表现出了三个突出的特点:农业生态史与城市环境史研究并重;强烈的南方环境史研究取向;优秀的基础设施和平台建设。另外,对西蒙斯教授和娃岑博士的访谈也会有助于我们弄清楚英美环境史研究的联系与区别,有助于打破美国在国际环境史研究领域的话语霸权。
