Local Economic Development is (LED) an activity of increasing importance in the developing world as globalisation produces new roles for local governments. As compared to a growing number of urban initiatives for LED, rural LED initiatives are relatively undeveloped. In this paper, the focus is upon South Africa, where the post‐apartheid government has sought to encourage both urban and rural LED initiatives. Programmes of land reform and restitution in South Africa result in the resettlement or return to the land of communities formerly dispossessed under apartheid. A critical element of planning for successful resettlement is the implementation of LED programmes. Schmidtsdrift in Northern Cape is examined as an example of participatory LED in a developing rural context. Rural LED in South Africa is distinguished by its focus upon poverty alleviation in the context of addressing the legacies of apartheid.  相似文献

Volunteer tourism as a subset of alternative tourism is the focus of analysis. This paper contributes to the limited writings on volunteer tourism by investigating the activities in South Africa of Habitat for Humanity, a grassroots ecumenical Christian organization that works in partnership with communities to eliminate poverty through the provision of shelter. A profile of the volunteer tourist and of their tourism experience in South Africa is presented which is based largely upon the return of 123 questionnaires from volunteer tourists in South Africa working with the local branch of Habitat for Humanity. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

In South Africa the tourism industry has been targeted as one of the key sectoral drivers for economic development and transformation of the country over the next two decades. A special feature of the South African tourism economy, which is a legacy of the apartheid period, is that the overwhelming majority of tourism enterprises and of the tourism economy as a whole is under the ownership of the white minority. With the post-apartheid transition, the national government recognizes that this unequal ownership structure in tourism needs to be addressed through a programme of transformation and consolidated support for the development of black owned tourism enterprises, especially of small tourism enterprises. The objective in this paper is to examine the problems and challenges that face the transformation of South Africa's contemporary tourism economy by investigating the development and constraints upon the country's emergent small black-owned accommodation sector in the form of bed and breakfast establishments.  相似文献

Radiocarbon dates obtained on organic materials overridden by a gelifluction lobe allow some estimate of past gelifluction rates for a site near sea level in northern Labrador. The calculated mean gelifluction rate for the last 400 years is in the order of 8 mm yr?1, somewhat higher than the average gelifluction rate described from other locations in the Canadian Arctic. The lobe contains two lithostratigraphic units: an inner diamicton, probably representing a buried gelifluction lobe, overlain by a silt/clay unit which may have been emplaced abruptly as a solifluction sheet. Mean creep rates for these units were in the order of 5 mm yr?1 and 15 mm yr?1 respectively. The area is presently subsiding, and transgressive beach material overlies terrestrial organics which are approximately 300 years old.  相似文献

Change detection thresholds for remotely sensed images   总被引:4,自引:0,他引:4  
 The detection of change in remotely sensed images is often carried out by designating a threshold to distinguish between areas of change and areas of no change. The choice of threshold is often arbitrary however. The purpose of this paper is to offer a statistical framework for the selection of thresholds. The framework accounts for the facts that one carries out multiple tests of the null hypothesis of no change, when searching for regions of change over an image with a large number of pixels. Special attention is given to global spatial autocorrelation, which can affect the selection of appropriate threshold values. Received: 8 March 2001 / Accepted: 12 October 2001  相似文献

This paper examines the development of Japanese involvement in South African manufacturing. In the extensive literature dealing with the growth and spread of Japanese investment abroad the unique situation of Japanese companies in South Africa has been overlooked. Despite the introduction of a ban on direct investment in South Africa there is a considerable hidden Japanese presence in local manufacturing which resulted from licensing arrangements. In particular, Japanese enterprise is strongly represented in the South African motor-vehicles sector where it is at the forefront in innovating new flexible production systems.  相似文献

The aim is to examine issues of defence economic restructuring and conversion in South Africa. Under the new government, overall restructuring of the South African defence sector is occuring. With diminished defence expenditure, the military industry is encouraged to convert production capability to non-military products. The geographical implications of defence economic restructuring and conversion in South Africa are analysed in the context of international experience and debates. The Gauteng region emerges as the national gunbelt of South Africa and contains an incipient military industrial district. In this particular region, the question of defence conversion is critically important for local policy makers and should be linked to new local economic development initiatives.  相似文献

Akthough issues surrounding the location and relocation of environmentally hazardous industry have attracted international attention, little research has been undertaken in South Africa. The aim is to analyse the geography of dirty industries in South Africa and suggest avenues for future research. The location of environmentally hazardous production in South Africa has not followed the national industrial trend towards polarization reversal.  相似文献

Sun International is a tourism multinational corporation (MNC) based in South Africa. The aim is to examine the formation and geographical spread of activities of this South African MNC engaged in casino-resort development and luxury tourism. Within the geographical literature on MNCs the study of Sun International underlines both the importance of country of origin as a factor in interpreting the heterogenous character of MNCs and of the distinctiveness of South African MNCs. The spatial scope of Sun International (including its ancestor, Southern Sun) operations was influenced by the enterprise's association with apartheid. Despite several efforts to mask its South African origin through restrictive corporate disclosure and corporate camouflage, planned international expansion was continually frustrated by the stigma of apartheid. Sun International was confined in its international operations to those African states which either were economic or political satellites of South Africa or to the group of independent Bantustans, which were creations of apartheid.  相似文献
