Abstract

The teaching of economic geography has received considerable attention in the literature over the last three years. This paper contributes to the debate by illustrating and analyzing a project based at the University of Arizona, the Arizona Community Data Set (ACDS). The ACDS is a long‐term field‐project that has given students the opportunity to go in the field to collect and analyze regional economic data and to apply theory and techniques learned in the classroom. This unique data set has yielded additional benefits in the area of basic research. It is argued that projects such as the ACDS complement some of the theoretical and analytical curriculum developed and recently published by other instructors in economic geography. Furthermore, it is demonstrated that some of the limitations commonly associated with field projects, especially the cost, can partly be overcome through sponsorship by community agencies.  相似文献

Abstract

Semi-arid landscapes are vulnerable to cultivation, overgrazing and climate variability, although it is difficult to identify the relative significance of these three factors. In the South African Karoo, the ‘desertification debate' seeks to explain a change to more shrubby vegetation in heavily grazed areas. We examine these issues in catchments where farm reservoirs provide sediment stores with 137Cs, 210Pb, geochemical and mineral magnetic signatures. Rainfall data and stocking numbers are reported and current erosion rates are estimated. Sediment accumulation in the reservoirs increases between 1935 and 1940, probably due to rises in the frequency of rainfall events of >25mm day. Significant increases in sedimentation rates (×8) occur during rain-fed wheat cultivation. In an uncultivated catchment, sediment yields remain relatively high and reflect increases in erosion from hillslopes, colluvial storage, and cultivated land sources. Gully systems have acted as transport routes rather than sediment sources over the last ~70 years. Badland erosion rates average ca. 50t ha?1 yr?1. At Ganora, their development in the 1920s strongly influences peak sedimentation between 1970 and 1980. Any delay between badland initiation and increased sediment yield appears to be a function of landscape connectivity. Recovery following disturbance is occurring slowly and is likely to take >100 years. De-stocking and better management systems are reducing erosion rates but may be offset by increases in rainfall intensity.  相似文献

On 3 May 2010, a ‘Call to reason’ (Appel à la raison) was presented to the European Parliament in Brussels by a number of prominent figures from European Jewish political and intellectual classes, launching JCall, which is supposedly the European version of the US J Street. JCall explicitly positions itself as pro-Israel on one hand but against the Israeli state's occupation and increased settlement of Palestine, including East Jerusalem, on the other hand. The ‘reason’ it calls for is thus a negotiated two-state settlement to the Israeli–Palestinian conflict and the organisation urges EU governments to apply pressure on both Israel and the Palestinian Authority to this end. This article looks at JCall within the French context, first in distinction to J Street in the USA, with which JCall shares a political position but not organisational links, and second in relation to the broader French political debate about Jewishness, Muslimness and the Middle East. Criticised by the right for its supposed disloyalty to Israel and even ‘anti-Semitism’, and by the left for its non-support of boycott, divestment and sanctions and its ongoing support of the Israeli state, JCall at first appears as somewhat middle-of-the-road in the French context. It also, from this writer's point of view, regrettably lacks a strong female presence or gendered perspective. It has, however, emerged as a serious political voice in the debate over the Middle East and could be less of a lightweight in the French political battles over Israel and Palestine than it may have first appeared.  相似文献

The source material that records the history of the Third Crusade gives the impression that Richard was a king who found it easy to interact with people from different backgrounds. Though he was one of the greatest warrior-kings of the medieval era, he was comfortable with churchmen and knights, with Frenchmen and Anglo-Normans, with lords and clerks, with his men and his father’s men. No doubt every royal court was a bustling, perhaps nearly chaotic, environment, but the individuals found in this study indicate that the court of Richard I was not an ivory tower to which only his barons had access.  相似文献

While scholars of contemporary philanthropy have observed a concerted interest in the promotion of ‘self-help,’ little has been said about the political history of this investment and its significance in determining both domestic and international development priorities. We locate this modern conceptualisation of self-help in early twentieth-century philanthropic practice that sought to ‘gift’ to individuals and communities the precious habit of self-reliance and social autonomy. The Rockefeller Foundation promoted rural development projects that deliberately sought to ‘emancipate’ the tradition-bound peasant, transforming him or her into a productive, enterprising subject. We begin by documenting their early agricultural extension work, which attempted to spark agrarian change in the US South through the inculcation of modern habits and aspirations among farmers and their families. These agrarian schemes illustrate the newfound faith that ‘rural up-lift’ could only be sustained if farming communities were trained to ‘help themselves’ by investing physically and psychologically in the process of modernisation. We then locate subsequent attempts to incentivise and accelerate international agricultural development within the broader geopolitical imperatives of the Green Revolution and the Cold War. While US technical assistance undoubtedly sought to prevent political upheaval in the Third World, we argue that Rockefeller-led modernisation projects, based on insights gleaned from behavioural economics, championed a model of human capital – and the idea of ‘revolution within’ – in order to contain the threat of ‘revolution without’. Approaching agricultural development through this problematisation of the farmer reveals the ‘long history’ of the Green Revolution – unfolding from the domestic to the international and from the late nineteenth century to the present – as well as the continuing role of philanthropy in forging a new global order.  相似文献
