From the late nineteenth century, both Argentina and Chile were integral parts of Britain’s ‘informal’ empire in Latin America. It has been suggested by historians that this ‘informal empire’ came to an end around the mid-twentieth century. By analysing contemporary sources from within the British government and the findings of later economic historians, it is the purpose of this article to contest this viewpoint. It will instead argue that the end of ‘informal’ empire in these countries was a direct consequence of the First World War, and that the decline in British influence in the region was registered by British policy-makers much earlier than has previously been argued.  相似文献

This paper describes the hitherto unreported occurrence of mid‐Holocene mangrove deposits in the Richmond River estuary, southeastern Australia, thereby providing evidence for changes in the distribution and composition of mangrove communities within a subtropical estuarine system during the Holocene. Stratigraphic, radiocarbon and palynological evidence indicates that widespread development of mangrove communities took place in the upstream reaches of the Richmond River estuary during the period 7000 to 6000 years BP. These communities maintained their habitat through substrate aggradation under the conditions of a moderate sea‐level rise, in contrast to other estuaries within the region, which generally experienced the submergence of intertidal substrates. Mangrove species belonging to the family Rhizophoraceae, most likely Bruguiera gymnorrhiza and Rhizophora stylosa, dominated these communities, in strong contrast to contemporary communities, which are dominated by Avicennia marina. Moreover, these mid‐Holocene communities were located a considerable distance upstream of the contemporary occurrences of Rhizophoraceae species within the estuary. The changes in the spatial distribution and composition of mangrove communities parallel the large‐scale evolution of the estuary driven by sea‐level variation. Shallow, buried Pleistocene terraces probably contributed to the regionally unique aggradational response of the mangrove communities and their substrates to a sea‐level rise during mid‐Holocene times.  相似文献

A noted specialist on the Russian economy presents an assessment of the impact of the global financial crisis on the mechanism of the country's economic growth. Focusing on the demand side of the economic ledger, the author explores the question of whether Russia will be able to re-attain the high economic growth rates of the period from 2000 to 2007 after recovering from the crisis. The paper analyzes the sharp drop in production in 2008 and the first quarter of 2009, attributing most of the damage to liquidity problems and declines in the price of oil. Empirical evidence is based primarily on data collected by the author from the Central Bank of Russia and the country's federal bureau of statistics (Rosstat).

A senior World Bank economist presents a study focusing on issues controlling Russia's accession to the WTO in 2007. The paper discusses the principal reform commitments that Russia has made in an effort to become a member of the organization and addresses the question of whether the country faces excessive demands due to political considerations. While exploring such issues as potential relations with foreign exporters and investors, the author summarizes the relevant parts of his recent joint study of Russian import tariffs that casts a new light on a complex aspect of international trade. Among other problems relating to Russia's entry, he discusses in some detail branch banking and the tradedistorting subsidies in agriculture.

Financial crises are not a new phenomenon. We had them in the 18th century; there were several well-known ones in the 19th century, not to mention the crisis which started the Great Depression of the 1930s. The recurrence of financial crises in the last decades has revoked a wave of research on the topic among economic historians and economists. Still, it has been difficult for us to really understand how these crises emerge, why they have been so severe recently and why they have occurred so often in the last decades. This paper tries to explain the phenomenon by asking, how is, and how was the volume of money stock determined, and why does scarcity of money, and thus rising interest rate, not check excess borrowing and creation of speculative bubbles - and then emerging crises.  相似文献

Abstract

One of the basic areas of interaction between water as natural resource and human societies as agents of cultural transformation is the technology of irrigation. In Africa at least 66 per cent of the available water is used for purposes of irrigation. For more than 4 000 years irrigation has secured food supplies for humans on a continent that is noted for its relative shortage of sufficient natural water supplies.

There is a remarkable hidden power of water in the history of southern Africa. This is particularly the case when we consider the development of early irrigation technologies of Iron Age farmers. The small irrigation furrow of the subsistence farmer was just as important to an insular community of Bantu-speaking people in pre-colonial times, as is the sophisticated irrigation technology in present-day South Africa. Currently there is a paucity of information about pre-colonial indigenous irrigation technology. This can be ascribed to a number of factors of which the invasion of modern Western traditions in the nineteenth century is perhaps the most important. A number of other factors for the apparent blind-spot is also presented in this study.

In southern Africa there are traces of indigenous pre-colonial irrigation works at sites such as Nyanga in Zimbabwe; the Limpopo River Valley; Mpumalanga; and South Africa's eastern Highveld. Reference is also made in this article to specific strategies of irrigation used by Iron Age communities, prior to the advent of a colonial presence. Finally, attention is also drawn to pre-colonial land tenure and state formation against the backdrop of Wittfogel's theories on hydraulic society.  相似文献
