The later Holocene spread of pastoralism throughout eastern Africa profoundly changed socio-economic and natural landscapes. During the Pastoral Neolithic (ca. 5000–1200 B.P.), herders spread through southern Kenya and northern Tanzania—areas previously occupied only by hunter-gatherers—eventually developing the specialized forms of pastoralism that remain vital in this region today. Research on ancient pastoralism has been primarily restricted to rockshelters and special purpose sites. This paper presents results of surveys and excavations at Luxmanda, an open-air habitation site located farther south in Tanzania, and occupied many centuries earlier, than previously expected based upon prior models for the spread of herding. Technological and subsistence patterns demonstrate ties to northerly sites, suggesting that Luxmanda formed part of a network of early herders. The site is thus unlikely to stand alone, and further surveys are recommended to better understand the spread of herding into the region, and ultimately to southern Africa.  相似文献

This article examines the role of the Irish co-operative movement in the early twentieth century and argues that it played a crucial role in shaping a popular understanding of the “Irish Question”. This mass-membership movement impacted upon the development of the Irish state and population. By taking this rural, social movement as a lens to analyse Irish society in the early twentieth century, social and economic issues re-emerge as central components to a contemporary understanding of Ireland's increasingly contested position within the Union. As the expectation of some kind of political resolution to demands for political independence grew during the First World War, radical nationalism absorbed a social and economic discourse that originated within the co-operative movement in its critique of the British state as it operated in Ireland. Irish co-operation represented a sophisticated form of political economy that provided an influential ideological platform for Irish nationalists as they anticipated some form of political independence.  相似文献

A recursive dynamic regional Computable General Equilibrium model is developed to assess the economic impacts of two Common Agricultural Policy (CAP) scenarios in six NUTS-3 (Nomenclature of Territorial Units for Statistics) (NUTS-1: major socio-economic regions, NUTS-2: basic regions for the application of regional policies, NUTS-3: small regions for specific diagnoses) regions of the European Union (EU). The main goal of the analysis is to assess the scenario effects (change in production, prices, income, employment) in the rural and urban parts of these regions as well as on the different sectors. The two scenarios analysed are related to a 30% reduction in Pillar 1 (market measures and direct support to farmers) support and the introduction of an EU-wide flat rate level of Pillar 1 support complemented by a 45% increase in Pillar 2 (Rural Development Policy) funds. Results show that the overall gross domestic product effects are not significant, due to the relatively low importance of both the agricultural sector and CAP spending in the regional economies. However, impacts on the agricultural sector are quite important and differ according to the nature of the policy shock. Also, the structural characteristics of each case study influence the rural–urban and sectoral spillovers, including impacts on region-specific agricultural activity.  相似文献
