Sediment yield in South Africa — A preliminary geographical analysis

The study examines the spatial relationships between sediment yield and 15 independent environmental variables in 54 catchments in South Africa. Rooseboom's (1978) data on the sediment yield from the catchments were standardized for a single time period. Bivariate regression analyses reveal no simple relationships. Multivariate regression analyses conducted for the whole and various sub-areas of South Africa indicate that latitude and longitude are the primary variables affecting spatial variations in sediment yield. This may be as a result of latitude and longitude being surrogate variables reflecting variation in other environmental variables (e. g. geology, vegetation). Within the sub-areas, 43.4% to 97.8% of the variation in sediment yield is explained by the combined variation in a number of different environmental variables. This study highlights a need for the collection and analysis of more sediment yield data, which would allow the analyses to be refined, to predict sediment yields from ungauged catchments in South Africa.     

Environmentally hazardous industry in South Africa: A spatial view

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.     

The silent articulation of private land rights in Soviet Estonia: A geographical perspective

With an explicit focus on the spatial articulation of landownership, this paper explores various ways in which pre-Soviet land rights were expressed in rural Estonia during the Soviet period (1940-1941, 1944-1991). Drawing on cartographical analyses and interviews made in the rural district of Muhu, the paper demonstrates that people who owned land before the Soviet occupation kept track of the officially annulled pre-Soviet land rights, by relating to inertial landscape elements as memory-aids. To local inhabitants the landscape, in which past and present structures always merge, provided substantial evidence in support of the idea of legal continuity of pre-Soviet land rights. Hence, the post-Soviet land restitution reform often implied a re-discovery or re-expression of property rights that had been silenced, but not lost.     

Poverty and HIV prevalence in Ghana: a geographical perspective

There is a widespread belief that poverty leads to the spread of HIV/AIDS. However, intra-country comparisons of the phenomenon have been limited. This study seeks to fill this gap by examining the relationship between poverty and HIV prevalence amongst the 10 administrative regions of Ghana. Based on the available data for poverty and HIV, certain distinct patterns emerge. For example, poverty levels are the highest in the three northern regions (Upper East, Upper West and Northern region) even though their HIV prevalence is one of the lowest. It clearly follows that there are more complex forces at work than just the effects of poverty alone. To unravel some of these puzzles, the paper proposes a key role for culture, globalization and geographical accessibility. In addition, it is suggested that local level studies in a multivariate framework have much to contribute to the identification and quantification of relevant relationships.     

Invisible towns: A case study in the cartography of South Africa

Many large Black settlements are downgraded or made invisible on maps of South Africa. This form of subjective generalisation gives a false prominence to small White towns. A more realistic map of the major settlements in South Africa is presented. The problems associated with mapping of Black settlements are discussed. These include the lack of census data, absence of official recognition of places, difficulties of place naming and the lack of functional imcomparability with other places.     

The co-production of livelihoods and land use change: Case studies from South Africa and Ghana

Land use change and livelihood systems are often analyzed separately or with one “driving” the other. This “driver-feedback” relationship has been buttressed by approaches to social process that are often far too static. Actors are confronted with a bundle of choices that they must negotiate as they create pathways of change. These choices are always bound up in relations of power and the knowledges that are the conditions for and results of these relations. We suggest that land uses and livelihood are different manifestations of the social processes by which individuals and groups negotiate the everyday conditions that shape their lives. We propose a framework that extends current understandings of the relationship between land use change and livelihoods by treating social relations of power as the entry point into this complex relationship. We underpin our arguments with empirical examples from South Africa and Ghana that locate power/knowledge relations in the context of social change in both study areas.     

The continuity of Basque political violence: A geographical perspective on the legitimisation of violence

After twenty years of parliamentary democracy in Spain the Basque liberation movement ETA is still using violent methods. Considerable support for ETA has persisted in the Spanish Basque Country. Based on voting patterns in Euskadi the persistent support for ETA is studied. ETA support through voting for its political wing Herri Batasuna is concentrated in specific areas. Through ecological analysis the relative weight of cultural, socio-economic, demographic and locational factors in voting patterns is determined. At a local level particular cultural contexts reproduce support for violent separatism. The continuity of violence legitimisation is a Spanish Basque phenomenon as it is confined to the Basque-speaking parts of Spain. The small-size settlements of the Basque Country offer a context of social control which enables mass legitimisation of political violence.     

A petrologist in South Africa: Frederick Henry Hatch and the Witwatersrand Goldfield

The English geologist, Frederick Henry Hatch (1864–1932), today mainly recalled for a textbook on igneous petrology, emigrated to South Africa, where, in the years between 1892 and 1906, he became one of the pioneers of the geology of the Transvaal and the Witwatersrand Goldfield. This article reviews his life and, in particular, his work during this period which led to his becoming a mining geologist with connections to many of the world's goldfields, set against the political background of the Boer War which influenced the course of his work.     

Social justice and access to legal services: a geographical perspective

This paper discusses the theory, method and results of the Exeter Access to Justice in Rural Britain project which examined the question whether rural inhabitants are disadvantaged in terms of their access to legal services by comparison with people in urban areas. Analysis of the spatial distribution of solicitors in private practice in England and Wales revealed rural areas to be relatively well provided for. An interview survey of a random sample of solicitors in Devon and Cornwall showed some important differences between rural and urban solicitors, with the former being less specialized and more conservative in orientation. A parallel survey of managers of CABs, providing a limited legal service, also revealed some perceived differences between rural and urban bureaux and some spatial unevenness in distribution. Surveys of rural clients, supported by parallel studies elsewhere in Britain, suggest that remote rural communities harbour cases of considerable deprivation with respect to legal services.     

Early Cambrian radiation of brachiopods: A perspective from South China

Brachiopods, a group of benthic suspension-feeding marine invertebrates, made their first appearance in the Lower Cambrian. In the Yangtze Platform (South China), well-exposed Lower Cambrian stratigraphic succession represents shallow to deeper water environments. Strata from eastern Yunnan, southern Shaanxi and the Yangtze gorges areas of western Hubei Province, deposited in muddy-siltstone and carbonate lithofacies, contained an abundant variety of brachiopods, including all the representatives of the subphylum Linguliformea and the calcareous-shelled genera of Kutorgina and Nisusia from the subphylum Rhynchonelliformea. Thus the fossil assemblage bears witness to the first major phase of evolutionary radiation of brachiopods during the ‘Cambrian explosion’ interval of metazoans. Brachiopods from the celebrated Chengjiang fauna have exquisitely preserved soft-tissues, which reveal the body plans and evolutionary acquisition of morphological novelties of the early stocks, and also provide a good opportunity for testing the analogies with the stem groups from the extant representatives. These fossils have corroborated the view that brachiopods developed complex organization of tissues, and achieved considerable evolutionary success already by the onset of ‘Cambrian Explosion’. Thus it is not improbable that a large part of this radiation occurred within, or only just before early Cambrian time. Studies of Chengjiang brachiopods suggest that attachment by a pedicle to the substrate was probably the most common relationship of Cambrian brachiopods with the substrate where they inhabited.     

Crossing the racial divide: a spatial-ecological perspective of offenders in the City of Tshwane Metropolitan Municipality, South Africa

Post-apartheid South Africa has been plagued by an increase in crime and a concomitant increase in the number of incarcerated offenders. Researchers have postulated many proximate causes for the insidious increase in crime, including the vast socio-economic inequalities existing in the country, a remnant of apartheid-era policies and post-apartheid migrations. This article focuses on the neglected field of the environmental criminology of offenders. Following a spatial-ecological approach the relationship between various socio-economic variables and offender rates in the City of Tshwane Metropolitan Municipality in South Africa is modelled. The GIS-based methodological procedure includes a crime offender index, correlational analysis and principal components analysis and produced five factors: social status and income, family characteristics, unskilled earner, residential mobility and ageing population. These five factors, accounted for almost 75% of the variance in the offender index. The findings of our research reject race as a determinant of crime, and rather highlight existing and emerging socio-economic inequalities in the globally connected post-industrial city in regions of political instability and economic uncertainty and its relationship with crime and crime prevention.     

Mapping land cover change of the Luvuvhu catchment, South Africa for environmental modelling

Considerable land cover changes have occurred in the Luvuvhu catchment in northeastern South Africa in the past two decades. These changes are associated with human population growth and may be contributing to observed reductions in winter river baseflows and increased episodes of river drying within Kruger National Park. Six-class land cover maps of the catchment were created from 1978 (MSS) and 2005 (TM) Landsat imagery using an iterative technique. Results indicate a 1,000 km² (12%) increase in Bare Ground between 1978 and 2005, with a concomitant decrease in shrubland and indigenous forest cover. Overall classification accuracy in the 2005 image was 80%. Classification was most accurate for Water and Pine classes (100 and 92%) and least accurate for Indigenous Forest (46%), primarily due to misclassification as Shrubland. These maps are suitable for land cover change and landscape modeling analyses, and can serve as baseline data for further research.     

Neoliberalism and privatisation in South Africa

Perhaps the defining characteristic of development as a global discourse is its neoliberal character. Even recently liberated nations such as South Africa have not escaped its reach. In South Africa, there has been a movement from a development policy with a socialist resonance – the Reconstruction and Development Program (RDP) – to one decidedly neoliberal in form and substance – the Growth Employment and Redistribution (GEAR) policy. The articulation of neoliberalism through development policy is being facilitated through a series of measures among which are fiscal austerity, export oriented production and the privatisation of public sector services. While the GEAR policy, as a macroeconomic framework, is being contested by labour unions it is privatisation which is facing widespread opposition among communities. My intention is twofold, firstly, to investigate how neoliberalism as a global hegemonic discourse has succeeded in capturing, colonising and repackaging the development imaginary of the African National Congress (ANC). Secondly, I wish to examine how privatisation as a sub-discourse of neoliberalism is being articulated in the historically black township of Chatsworth, in Durban.

Factors affecting the mechanization of the tillage operation of paddy fields in Sri Lanka: A geographical perspective

In Sri Lanka where the paddy farmers' income is low and tractor hire rates are considerably high, paddy farmers' tendency to use tractors for tillage operation can hardly be explained in rational terms. However, this paper attempts to assess the significance of some selected socio-economic and physical factors which are considered to be effective in generating compelling grounds to use tractors for the tillage operation of paddy fields.Three socio-economic variables relating to shortage of labour, shortage of buffaloes and limited time available for the tillage operation, which were considered to be crucial in determining the farmers propensity to use tractors, were regressed on the degree of tractor utilization; and then the residuals from the regression were mapped. Then, the map of residuals was compared with the map of agro-climatic regions in order to ascertain the impact of agro-climatic conditions on tractor utilization.It was found that the three socio-economic variables collectively explain 51% of the spatial variation of the degree of mechanization. The map of residuals was found to mostly coincide with the map of agro-climatic regions. While all positive residuals were found to be in the dry zone and in the arid zone where the soil is very dry and hard, only negative residuals were found in the wet zone where the soil is wet and soft. Therefore, it seems that the spatial variation of the degree of mechanization which cannot be explained by the selected socio-economic variables may be attributable to the spatially varying soil conditions.It can be concluded that the selected socio-economic factors and the agro-climatic factors pertaining to dryness and hardness of soils collectively encourage or compel Sri Lankan paddy farmers to use tractors for tillage operation.     

Earth Science Education in South Africa

Most of the statistics given in this overview of the history and current status of Geoscience Education in South Africa pertain to the more geologically inclined disciplines; while the report does mention the extent to which earth sciences are taught in mining and geography departments, no detailed information about these activities are given. There are 13 active geoscience departments countrywide (eleven at universities and two at technical institutions) teaching a wide range of geological topics, some at a highly specialised level. There are just over 100 academic staff members engaged in teaching, supported by 65 technical and administrative staff. Of the teaching staff, 89% have Ph.D. degrees, and most are engaged in active research. About 150 three-year B.Sc., slightly fewer B.Sc. (Hons.), graduates, plus 10 geological technicians pass through the system every year, with most finding employment in the mining industry. Approximately 120 M.Sc. and 60 Ph.D. candidates are currently registered at the universities, about 40% of whom graduate in any particular year.

The study of tourism in Britain — a geographical perspective

Conclusion This review must be seen alongside others which have attempted to explore the relationship between geography (and geographers) and the study of leisure and recreation (Coppock 1980, 1982a). It serves to confirm the wide-ranging and diverse contribution that geographers have made in this field and the ways in which the study of tourism has reflected developments in the wider discipline. It also confirms the very close and intimate connection between studies of tourism and social and economic policy in Britain and indicates the way in which geographers have attempted to shape policy and have in turn been influenced by the needs and demands of policymakers. The rewards of such interaction are clear and yet costs have also been incurred by the academic geographic community. Not the least of these costs is that tourism studies have been predominantly of an empirical nature and conceptual and theoretical advance has inevitably tended to lag behind these empirical investigations. It is to be hoped that the study of the geography of tourism, having now demonstrated its credentials to policymakers and decision-makers alike, can secure for itself a more central place within geographic teaching and research so that these lacunae can be remedied.
