▼ The main millennium development goal is to eradicate extreme poverty and hunger in the world by 2015. South Africa is one of the countries that signed this pledge at the millennium summit in 2000. The Department of Agriculture, has initiated a number of projects to assist farmers and communities with reaching this goal. In the Northern Cape, the commercialization of goats is one such anchor project. The major activities of this project is to train farmers in applied and appropriate production practices, assist them with accessing markets and supporting them with improved livestock. The main aim of this research was to evaluate whether the project has achieved its outcome and whether this outcome, is having an impact on the livelihoods of the farmers involved in the project. After reviewing the literature on evaluation research and programme evaluation across time, the different paradigms and approaches, participatory methodology was used in this study. A case study approach was applied to evaluate the outcomes and effects of the training received by farmers, as part of the commercialization of goats programme. The results of the study proved that the training received by members of the Campbell Agricultural Co-operative Enterprises, changed their goat production practices. The training also had a secondary impact. Trained farmers were imparting (technology transfer) their acquired knowledge to other members of the co-operative. This appeared very effective as all members of the cooperative were farming more scientifically. These changes to the production practices had a positive impact on the livelihoods of the farmers, as their animals were of a better quality and they were able to sell their animals at different markets and for better prices. This has however not commercialized their farming operations as they are still faced with many challenges. These challenges are the lack of a proper marketing structure, access to financial assistance, proper infrastructure and adequate transport for the animals to mention a few. If the Department of Agriculture and Land Affairs is serious about assisting these farmers to move from the status of “emerging farmer” to “commercial farmer” they will have to look at addressing the problems experienced with financial access and access to adequate and appropriate transport.

▼ M.Sc.
This dissertation describes the N1 manganese ore bed at Gloria Mine in the Kalahari Manganese Field, Northern Cape Province. It also compares the ore bed at Gloria Mine with the correlative bed further to the south at Mamatwan Mine. The ore bed at Gloria Mine can be subdivided into ten texturally distinct zones that are laterally consistent throughout the mine lease area. The mineralogy and geochemistry of the various lithostratigraphic zones are described from two drill cores (GL28 and GL24), situated away from any known structural features or unconformities that could have affected the properties of the Ore. The ore in drill core GL28 has a mineralogical composition similar to that of typical Mamatwan-type ore described at Mamatwan Mine with braunite and kutnahorite as the main minerals. However, in drill core GL24 the ore has a very different mineralogical composition although it is texturally and geochemically rather similar to Mamatwan-type ore. The ore is composed of hausmannite, calcite and jacobsite and is apparently related to a post-depositional alteration event that did not effect Mamatwan-type ore in the Mamatwan Mine area. This altered ore is similar in composition to low-grade leastaltered manganese ores in the cores of fault blocks at Wessels and N’Chwaning Mines i.e. the area known for its hydrothermally altered high-grade manganese ores in the northern part of the Kalahari Manganese Field. In addition to the above, the N1 manganese ore bed at Gloria Mine also underwent ferruginisation close to certain joints and normal faults. No obvious alteration could be detected where the ore bed is unconformably overlain by Dwyka diamictite, nor associated with a thrust fault displacing the ore.

▼ The Postmasburg Manganese Field (PMF), located in the Northern Cape province of South Africa, plays host to significant deposits of iron and manganese that have been utilized since their discovery in 1922 by Captain L.T. Shone. Further afield, lies the massive high-grade manganese deposit of the Kalahari Manganese Field (KMF), which drew attention away from the PMF after its discovery. These deposits are not limited to iron and manganese ore, but contain significant assemblages of alkali-rich rocks - which is the focus of this study. The existence of alkali-rich assemblages beneath conglomeratic iron-ore on farm Langwervacht, has come under investigation in this study, and in particular, the enrichment of these rocks in Ba, Na and Mn. Petrographic analysis of the clast-supported conglomerate unit (ore-zone), has uncovered the presence of vugs (up to 8mm across) which contain barite, K-feldspar and fluorapatite. In addition to this, the ore-zone of one of the three boreholes contains late carbonate veins (kutnohorite), which travel along Fe-clast boundaries, and exploit clast-fractures and areas of weakness. Further down, within the ‘enriched-zone’ of alkalis, the mineralogy is more diverse - containing elevated concentrations of Ba, Na and Mn. Seventeen distinct minerals containing these three key elements have been identified - along with one solid-solution series in the form of hollandite-coronadite. The existence of minerals such as natrolite, aegirine, albite, banalsite, barite, serandite, celsian and hollandite-coronadite are indicative of hydrothermal activity having influenced these rocks. Bulk-geochemistry was used to compare the major and trace elements of each borehole and the associated units. Both the trace elements and the REE’s from the ore-zone are enriched by an average of 5-10x relative to the BIF standard used - which immediately suggests an influx of elements. Compared to PAAS (Post Archaean Australian Shales), the ore-zone REE’s are slightly depleted, but more importantly the profiles are very similar to that of the Mapedi shales achieved in previous studies. This result points towards a strong shale influence in the ore-zone protolith. Expectedly, many of the enriched-zone trace elements and REE’s show far greater enrichment than what is observed in the ore-zone. Trace and Rare Earth Element profiles between the ore-zone and the enriched-zone are, however, generally correlative, with profiles reflecting similar enrichments and depletions for a given element - even within different rock units. This suggests that the hydrothermal fluid has moved in a general upward direction, reacting with host-rock units, and relinquishing elements carried in solution - wherever conditions have been favourable for the accommodation of these elements. This study has shed light on the relationship between the ore-zone and the enriched-zone, and results suggest that the process of alkali enrichment is not directly related to the process of upgrading of the iron ores. This is due to the extent of the alkali-enrichment…

▼ D.Phil.
The Ongeluk Formation is a laterally extensive sequence of ≈2200 Ma tholeiitic basaltic andesites in the upper Griqualand West Sequence of the northern Cape Province. The stratigraphic thickness is about 500 m and the Ongeluk Formation underlies the ore-bearing strata of the Kalahari Manganese Field. The formation comprises massive lavas, pillow lavas and hyaloclastite beds in close association. These rocks were extruded under water in a marginal basin within the continental setting of the Kaapvaal Craton. The Hekpoort Basalt Formation of the Transvaal is magmatically cogenetic with the Ongeluk, having indistinguishable geochemistry and sharing a stratigraphically related hiatus in Cr values. The best age estimate for the two formations is 2193 ± 71 Ma, from Rb-Sr data of two previous workers for Hekpoort samples. The Ongeluk Formation shows a mild "regional" geochemical alteration and a profound "Kalahari" alteration beneath the Kalahari Manganese Field. Geochemical screening was used to reconstruct the magmatic composition from a selected dataset. Three stages in the development of regional alteration are ascribed to sea water-rock interaction at different temperatures, and have distinct geochemical signatures. The pervasive Kalahari alteration is characterised by a purple colouration and the decoupled alteration of alkali and high field strength elements. It is due to the development of major hydrothermal systems close to a volcanic vent which are analogous to modern mid-ocean ridge systems. A multi-system isotopic study showed that most of the isotope systems were modified by sea-floor alteration. The similarity of the 2237 ± 23 Ma Pb-Pb errorchron age with the Rb-Sr Hekpoort age reflects changes in U-Pb ratios with minor changes in Pb isotope ratio. Evidence was found in the Rb-Sr system for a minor disturbance at ≈ 1100 Ma, also reported by previous workers. This event is related to the Namaqua tectogenesis, while no isotopic evidence was found for the enigmatic ≈ 2200 to 1750 Ma Kheis orogeny, regarded as the cause of thrust faulting in the region. A genetic connection between the Ongeluk lava and the Kalahari Manganese deposits was established. The manganese ores contain evidence for both marine and hydrothermal contributions to chemical sedimentation. Negative Ce anomalies characterise an oxygenated sea in which the interaction between global oceanic and continental influences is seen. Heavy rare earth enrichment reflects volcanic hydrothermal exhalations from the Kalahari Ongeluk system. Mass balance calculations show that the entire 9 billion tons of Kalahari Manganese ore could have been derived from the Ongeluk Formation. A new model describing the origin and evolution of the Kalahari Manganese Field places a strong emphasis on the role of the syngenetic hydrothermal exhalation and upgrading.

With this research, an Environmental Centre for the Northern Cape Province is suggested at Upington as an environmental management initiative. Environmental management aims to create an awareness and a concern for the environment and all its facets. In this way, knowledge, skills, attitudes, motivation and commitment are striven for, so that the environment and its related problems can be identified and solved by the community. Formal teaching cannot do this task by itself. An additional source is suggested. An Environmental Centre can benefit the community if it creates an awareness of the various elements of the environment, their interdependency and the necessity of a healthy environment for the survival of man. It can motivate the community to accept responsibility for the environment, provide the knowlegde and values so that solutions can be found for environmental problems. Upington in the Northern Cape Province has several unique qualities which can justify an Environmental Centre: • an unique climate with many human activities, • the availability of the Orange River's water, • its population composition, • Various economic activities(intensive/extensive farming) • a growing tourist sector, and • a very well developed infrastructure. A questionnaire was used to compile a residents profile to test the Environmental Centre initiative. Residents acknowledged the existence of environmental problems and that it must be addressed. An Environmental Centre with a well developed, co-ordinated and integrated environmental management plan, can be a solution. The way man sees his environment, indicates how he will utilise his environment. Knowledge and education about the environment can lead to citizens that know, understand and protect their environment against every form of deterioration. Environmental adulthood can thus be achieved.

▼ This document consists of three sections, and they are the academic paper (section 1), literature review (section 2) and research methodology (section 3). The academic paper consists of the purpose of the research, the summarised literature review, summarised research methodology and the research findings. The literature review section is a detailed review of literature used in this study. The research methodology section explains the research methodology and design which was employed in this study and it gives more details than the summarised version of the academic paper section. This summary integrated all the elements of section 1, section 2 and section 3. The purpose of this research is to identify the main problems that the Department of Environment and Nature Conservation (DENC) could encounter during the implementation and use of a performance management system, based on employee perspectives. The objectives of this research are therefore: to establish how often a particular problem has been encountered during the implementation and use of a performance management system in DENC; to identify the impact of various problems on the implementation of a performance management system, to establish whether these problems can be easily solved or not, and to analyse the problems associated with the implementation of a performance management system, as well as making recommendations for the successful implementation of a performance management system in the future. In this study, the researcher employed both quantitative and qualitative research approaches, informed by post-positivism as research orientation. The data collection techniques employed in this research include survey questionnaires and individual interviews. The survey questionnaire was answered by fifty respondents, and interview questions were answered by four respondents. The ethical issues were addressed by writing a letter to the Head of Department and getting authorisation to complete the research and informing respondents of their right to withdraw and to participate voluntarily. The findings indicate that the problems are either sometimes encountered or rarely encountered, and the division is about fifty percent of those sometimes encountered to those rarely encountered. This research indicates that most of the problems have a moderate impact on the use and implementation of a performance management system. The lack of management has a high impact, and a lack of positive attitude to performance management system (PMS) certainly has an impact on the use and implementation of the performance management system. Items such as the problem of information and communication technology (ICT) which does not support PMS adequately, and defining too many key performance indicators (KPI), have a small impact on the use and implementation of the performance management system. There are three problems which are difficult to solve and they are: lack of management commitment, organisational members‟ lack of positive attitude to the PMS and an insufficient period of…

▼ The research is aimed at identifying factors that impact on the performance of contractors during the implementation of construction projects and identify interventions to address poor performance. Eleven project parameters, eleven resources, nine functions in an organisation, and five functions and activities of management work from construction industry literature studies were used to determine the current practices by the contractors involved in the construction projects the study was undertaken in the Northern Cape Province among contractors registered on the CIDB database in Grades 1 to 5. A research questionnaire was used for the collection of data. Closed-ended questions were primarily used. The study recorded a number of significant findings. Forty-seven per cent of Northern Cape construction business owners have a high school education (matriculation), 20% a technical school qualification, and 13% a university qualification; 51% of businesses used personal savings as a source of funding for their projects. In addition, it was found that unless contractors perform relative to the eleven project parameters, they are unlikely to succeed in the workplace, or progress in terms of their registration with the CIDB. The study confirms the importance of business environmental factors which is found to contribute to the success of the emerging contractors if not properly analysed prior to engage in construction business practices. It is evident from the empirical study that emerging contractors do not have knowledge of the following: strategic leadership; the promotion of sustainable growth of emerging contractors; the promotion and improvement of performance and best practice, and the improvement of procurement and delivery management. Recommendations include the CIDB must perform its mandate by providing strategic leadership to all stakeholders involved within the construction industry, encourage best practice and provide guidance in terms of performance improvement of contractors, and provide a platform for clients to reward best practice and performance improvement.

▼ ENGLISH ABSTRACT : The Northern Cape, as part of the research context for this study, is characterised by specific economic and social problems, including a low socio-economic status, high unemployment, disintegrated family systems and substance dependency. Adolescents who grow up in such rural environments are exposed to the abovementioned obstacles on a daily basis. As a result, they may be more susceptible to the misuse of harmful substances. Limited research regarding substance abuse amongst adolescents in a rural environment is currently available. The objective of this study was to explore the viewpoints of Grade 11 learners in a historically disadvantaged rural community with regard to substance abuse amongst adolescents. A participant perspective was selected for the study, implying that the viewpoints of the Grade 11 learners were placed centrally in the study. In an effort to understand and describe the viewpoints of the Grade 11 learners on substance abuse amongst adolescents, a qualitative research design within an interpretivist paradigm was employed. Data were collected by means of an activity and individual and focus group interviews. The research results highlight four important themes. Firstly, several causes for substance abuse to be found within different systems were illuminated. In the second place, the reality and extent of the challenge amongst adolescents in the research community was shown, with a specific focus on the risks involved in the abuse of harmful substances. Thirdly, the potential contribution of the subject Life Orientation with regard to the prevention of substance abuse was highlighted. The deficits within the presentation of the subject also received attention. Finally, the participants made important recommendations with regard to the prevention of substance abuse and support for adolescents already using harmful substances. Collaborative partnerships to address the comprehensiveness of the challenge were emphasised.
AFRIKAANSE OPSOMMING : Die Noord-Kaap, wat deel uitmaak van die navorsingskonteks van hierdie studie, word deur bepaalde ekonomiese en maatskaplike probleme gekenmerk, wat insluit ʼn lae sosio-ekonomiese status, hoë werkloosheidsyfer, gebroke gesinstrukture en middele-afhanklikheid. Adolessente wat in hierdie plattelandse omgewing grootword, word daagliks aan bogenoemde hindernisse blootgestel. Dit mag hulle meer vatbaar maak vir die misbruik van skadelike middele. Beperkte navorsing oor middelemisbruik onder adolessente in ʼn plattelandse omgewing is tans beskikbaar. Die doel van hierdie studie was om Graad 11-leerders in ʼn histories-benadeelde plattelandse gemeenskap se sienings van middelemisbruik onder adolessente te ondersoek. Die studie het ʼn deelnemersperspektief aangeneem, dus is die Graad 11-leerders se sienings sentraal binne die ondersoek geplaas. In ʼn poging om Graad 11-leerders se sienings oor middelemisbruik onder adolessente te verstaan en te beskryf, is van ʼn kwalitatiewe navorsingsontwerp gebruik gemaak en die studie is vanuit ʼn…

Genesis of BIF-hosted hematite iron ore deposits in the central part of the Maremane anticline, Northern Cape Province, South Africa.

▼ The Paleoproterozoic Transvaal Supergroup in the
Northern Cape Province of
South Africa is
host to high-grade BIF-hosted hematite iron-ore deposits and is the country’s most important
source of iron to date. Previous work has failed to provide a robust and all-inclusive genetic
model for such deposits in the Transvaal Supergroup; in particular, the role of hydrothermal
processes in ore-genesis has not been adequately clarified. Recent studies by the author have
produced evidence for hydrothermal alteration in shales (Olifantshoek Supergroup)
stratigraphically overlying the iron-ore intervals; this has highlighted the need to reassess
current ore-forming models which place residual supergene processes at the core of oregenesis.
This thesis focuses on providing new insights into the processes responsible for the genesis of
hematite iron ores in the Maremane anticline through the use of newly available exploration
drill-core material from the centre of the anticline. The study involved standard mineralogical
investigations using transmitted/reflected light microscopy as well as instrumental techniques
(XRD, EPMA); and the employment of traditional whole-rock geochemical analysis on
samples collected from two boreholes drilled in the centre of the Maremane anticline,
Northern Cape Province. Rare earth element analysis (via ICP-MS) and oxygen isotope data
from hematite separates complement the whole-rock data.
Iron-ore mineralisation examined in this thesis is typified by the dominance of Fe-oxide (as
hematite), which reaches whole-rock abundances of up to 98 wt. % Fe₂O₃. Textural and
whole-rock geochemical variations in the ores likely reflect a variable protolith, from BIF to
Fe-bearing shale. A standard supergene model invoking immobility and residual enrichment
of iron is called into question on the basis of the relative degrees of enrichment recorded in
the ores with respect to other, traditionally immobile elements during chemical weathering,
such as Al₂O₃ and TiO₂. Furthermore, the apparently conservative behaviour of REE in the
Fe ore (i.e. low-grade and high-grade iron ore) further emphasises the variable protolith
theory. Hydrothermally-induced ferruginisation is suggested to post-date the deposition of the
post-Transvaal Olifantshoek shales, and is likely to be linked to a sub-surface transgressive
hydrothermal event which indiscriminately transforms both shale and BIF into Fe-ore. A
revised, hydrothermal model for the formation of BIF-hosted high-grade hematite iron ore
deposits in the central part of the Maremane anticline is proposed, and some ideas of the
author for further follow-up research are presented.

▼ M.Ed.
For many years, Environmental Education was marginalised in the school curriculum, as it was seen to belong with subjects like geography and biology. This alienated it from the majority of teachers who are not trained in science related subjects. Thus only few pupils, who happened to have studied under science oriented institutions or teachers, were exposed to this field of knowledge. On 24 March 1997, the national Ministry of Education launched a new Outcomes Based Education (OBE) system for South Africa, called Curriculum 2005. This marked the end of different education systems that had existed in South Africa, and also opened new avenues for cross curricular issues such as Environmental Education, which did not form part of the school curriculum in the past. The primary aims of the study are: to investigate ways in which Environmental Education could benefit and support Curriculum 2005; to document the process that led to the infusion of Environmental Education into the school curriculum; and to determine needs and problems of teachers implementing Curriculum 2005 and suggest possible solutions for their problems. The data for this study was collected by using qualitative techniques of consultative synthesis; group open-ended interviews; public forums; field studies; observations and literature research related to different aspects of Environmental Education activities. In addition, a questionnaire was used in four regions that constitute the Northern Cape Provincial Education Department. The realities are that teacher education programmes in many institutions do not include courses in Environmental Education. Education about the environment has not been a visible priority in many countries, including South Africa. As indicated in this study, the situation in the Northern Cape clearly gives evidence of this. On the other hand, teachers had serious misgivings about their competence to teach Environmental Education. The enthusiasm reflected by teachers in the province, their potential and willingness to learn, are but a few indications of the possible success of Environmental Education in the province. The major/main problem identified is the OBE terminology which seems to hamper the implementation of Curriculum 2005. Thus, the success of Environmental Education in South African formal education depends on how well teachers adapt to, understand, are prepared for and committed to Curriculum 2005. I believe that if Curriculum 2005 succeeds, Environmental Education will also succeed. If it fails, Environmental Education will probably fail too, since is regarded as an integral part of the curriculum.

▼ Maize is the most important grain crop produced in
South Africa, serving as a food source for humans and animals, an
input provider to other sectors, a source of job creation, a
contributor of value added to the national economy, and an earner
of foreign exchange. The
South African maize industry plays an
important role in the
South African economy and consequently its
role players should be supported to promote the industry. However,
since the abolishment of the agricultural marketing boards and the
deregulation of
South African agriculture, farmers have suddenly
found themselves exposed to global competition and a liberalised
economy. Maize prices are uncertain and volatile, leading to
increased risk. In addition, input prices have increased more
rapidly than maize prices in some instances, and since no
government protection exists, the cost squeeze effect places many
farmers in a financial predicament. In order to mitigate the cost
squeeze effect, farmers have started exploring farming methods and
strategies that can improve their financial position. Precision
farming (PF) is identified as a technological tool that can improve
the profitability of a maize farm through higher yields and lower
input costs, and can also indirectly assist in the general farm
management and financial functions on the farm. The literature
indicates that PF has been successfully implemented on various
occasions with subsequent benefits, whether financial or
qualitative. It could also be a useful tool to improve the
profitability of
South African maize farmers. Despite its various
benefits, PF is associated with high capital expenditures and
therefore farmers are reluctant to implement this technology on
their farms. However, a PF service system that requires little
capital expenditure is implemented by an agribusiness
(Griekwaland-Wes Koöperasie) in the
Northern Cape Province. Farmers
who are part of this program only pay PF service fees that are
charged on a perhectare basis. Most of the PF technologies and
knowledge are provided by GWK and/or affiliated fertilizer
companies, which subsequently mitigate the burden of high capital
expenditures. The general objective of the study was to investigate
the impact of PF on the profitability of selected maize irrigation
farms in the
Northern Cape Province. This was achieved by comparing
the profitability and risk position of selected farms under a
conventional farming (CF) system with the profitability of the same
farms when converting to a PF system. The specific objectives of
the study were to determine whether PF would generate better
profits than CF; to determine whether PF would improve the farmer’s
ability to repay his debt and generate an income (thereby improving
the financial survivability of the farm); to determine whether PF
would improve the debt-to-asset position of the farmer; and to
determine whether PF is less risky than CF with respect to net farm
income and cash position. The Bureau for Food and Agricultural
Policy (BFAP) farm-level model developed by Strauss (2005) proved

▼ ENGLISH SUMMARY : Background: Information on the patient provider encounter, in terms of the most prevalent reasons for encounter and diagnoses at the primary care level, may help not only to improve the quality and efficiency of primary care service delivery, but also to develop training programmes for primary care providers. This study aimed to determine the range and prevalence of the reasons for encounter and diagnoses resulting form provider-patient encounters in public sector primary care facilities in the Frances Baard District.
Methods: This descriptive cross sectional survey was conducted in the Frances Baard district situated in the Northern Cape Province. The study aimed to include 6000 consultations. This sample size was allocated to the sub-districts based on their respective populations. The facilities in each sub-district were then listed and divided into community health centres, fixed clinics or mobile clinics. Following this stratification, the required number of health centres, fixed clinics and mobile clinics were then randomly selected. In order to account for seasonality and pattern of attendance throughout the week, the 5 days on which patients were sampled were divided over a 12 month period and between different days of the week. Vertical programmes were excluded from this study as well as clinics attending to only one type of patients. Data were coded according to the International Classification of Primary Care-Version 2.
Results: In total 1504 consultations were captured and resulted in 2930 RFE and 1958 diagnoses. Among these consultations 1491(99.1%) were conducted by nurses versus 13(0.9%) by doctors. Overall the sex ratio showed 591(39.3%) male to 902(59.9%) female patients. There was no significant difference between males and females in the number of RFEs (p=0.36) or diagnoses (p=0.35). Age was not related to the number of RFEs (p=0.77) but was significantly related to the number of diagnoses (p<0.01). Older clients had a significantly lower number of diagnoses in comparison to younger patients. The top 20 RFE and top 20 diagnoses are presented overall, by gender and separately for children.
Conclusion: Cough, fever and throat symptoms emerged as the main RFE. In adults hypertension, acute URTI/tonsillitis, tuberculosis and HIV were the most prevalent diagnoses. Children were primarily seen for respiratory tract infection, gastrointestinal infection and immunizations. Nurses were seeing 99% of all patients and their practice was dominated by non-communicable chronic diseases and infectious diseases. Delivering quality public primary care would require a comprehensive support system for nurses to improve their capacity to respond appropriately to the common reasons for encounter and conditions identified in this survey. In particular there is a need to improve the recognition of mental health disorders and to foster a more bio-psycho-social approach.

▼ ENGLISH ABSTRACT: Introduction: High quality comprehensive health care services contribute to community integration and participation of persons with disability. However, persons with disabilities often experience barriers with regard to health care access. Neither these barriers nor the concept of disability have been sufficiently explored in rural Global
South settings. This study describes the experience of living with a disability in a remote, rural setting with a specific focus on barriers and facilitators to health care access.
Method: A qualitative design utilising case study methodology and interpretative phenomenological analysis was used. The study population consisted of 283 persons with moderate or severe activity limitations, who lived in a rural town in the
Northern Cape Province of
South Africa. Eight of them were purposively sampled as anchor participants in eight case studies. Their significant others completed each case study. In addition data were collected from six service providers to the study community. Data were collected through 19 in-depth interviews and one focus group discussion, between March and October 2012. The principles of interpretative phenomenological analysis were used to analyse data and identify themes. Similar themes were clustered under superordinate themes. Cases were analysed separately after which patterns across cases were identified.
Results: Participants conceptualised disability as an individual problem according to the moral or medical approaches and often interpreted disability as physical in nature. Participants’ level of participation and community integration varied from very little to being employed and well integrated. Self-belief and the attitude and support of significant others, community members and employers played an important role in the level of participation persons with disability achieved.
Participants’ primarily utilised public, formal, health care services. These services were found to be mainly curative and preventative in nature. The provision of health promotion and rehabilitation were lacking. Users were not empowered to take control of their own health management and were not included in the health care team. Health system barriers identified included insufficient human and material resources, communication challenges,

and rigid protocols. The remoteness of the setting hampered health care service delivery. Free health care provision, high quality services at tertiary level, and outreach services to the community were identified as facilitators. A lack of products and technology, poverty, and low levels of education created further barriers to community integration and health care access.
Implications: Suboptimal health care together with personal and environmental barriers might have resulted in poor health, functional, community integration, and participation outcomes for participants. Health care was provided reactively to individual users and not according to the principles of…

The problem that exists in the developing areas of the Northern Cape area of Eskom (and also in all other developing areas in South Africa), is to make the correct decisions in terms of electrification, marketing and sales of electricity and electrical appliances when electrifying these areas. This study investigates this problem. The results from field work before and after electrification and recommendations form the main part of the study. The main methods followed for this study were as follows: Previous pre-electrification studies over a period of roughly six years in 82 developing areas were aggregated into 33 tables with maximums, minimums and averages calculated, including compiling 52 graphs. This process took the best part of one year. This gives an in-depth combined view of energy - and socioeconomic aspects particular to the Northern Cape. A needs analysis was also done amongst role players inside and outside Eskom, inter alia the management of Eskom, municipalities, Rand Afrikaans University, electrical contractors and district councils. The most important needs were investigated during field work done for this study in 1994. Data processing in dBase and Microsoft Excel and statistical analysis in Statgraphics was done, and the findings were taken up in four internal before/after publications during 1995 and 1996 and finally, in this study. It provides a clearer insight into electrification -, socio economic and health aspects in the developing areas of Northern Cape before and after electrification. Electrification in developing areas in Angola, Zambia and Zimbabwe is uneconomical and in many cases has just about come to a standstill. Electrification in Namibia and Botswana is progressing slowly, at a cautious economic pace. Amongst the most important findings (in another 29 tables and another 58 graphs) for the Northern Cape area of Eskom are: The number of prepaid customers in the developing areas grew from less than 100 in 1989 to more than 38 000 in 1996, an increase of more than 20 000%. At this stage these customers of Eskom consume 4.148 GWh of electricity p.m., the equivalent of about 4 148 big households, each consuming 1 000 kWh (units) of electricity. This translates to only 109.16 kWh (Eskom ±70 kWh nationally)per customer p.m., which is not even nearly economical to Eskom. It must be remembered that it took 20 years in Ireland for electrification programmes to become economically viable. The target of Eskom in South Africa vary from 350 kWh to 572 kWh p.m., the latter which can only be achieved by "second phase" electricity consumption, i.e. by using heavy appliances such as geysers as well. When the developing areas have been fully electrified, total electricity demand in South Africa could increase by 7.4%, which could cause the building of another 1.26 big power stations. After electrification, there was a statistically significant reduction in the monthly average spending on wood and coal in the developing areas of Northern Cape. The electrical appliances mostly in use (after…

Natural phenomenon such as droughts have a definite influence on the availability of water sources, soil profiles and vegetation of an area. Man should adapt his activities, such as farming, to the current climatic elements of the area to ensure his existence. Intermittent rainfall and the occurrence of droughts caused symptoms such as desertification. Desertification has reached an alarming level in South Africa, so much so that the level of environmental degradation in the Northern Cape Province caused great distress. This caused many questions into the activities of man in this area. The problem that arose out of this is, does man cause a negative impact on the environment with his farming activities? The specific area of concern is the Southern Kalahari-dunefield, with its unique ecosystems. This area can be described as an semi-arid desert with very sensitive ecosystems. Any form of interference can cause a long term ecological disruption. This area contains several hidden resources which are optimally used by man and animals to live a decent life. The development of these resources (e.g. water) over the past decades lead to the advantage for all concerned. However, the real danger of over-utilisation and exploitation do exist. Questionnaires were used to gather data concerning stock farming activities in this area. Information was obtained regarding water resources, vegetation cover, endemic animals, type of farming, ground cover and other economic activities such as tourism. Man is an additional determinant who causes an impact on his environment in the Southern Kalahari-dunefield. Although a change can be observed over the past decades in the activities of man to enhance sustainable development, continuous strive to the implementation of new methods to preserve resources in the long term, must be encouraged.

It is the focus of the study to qualitatively describe and then quantify the mineralogical and geochemical changes associated with the supergene alteration of carbonate-rich braunite lutite (Mamatwan-type ore) immediately below the Kalahari unconformity along the southeastern suboutcrop perimeter of the Hotazel Formation in the Kalahari deposit. It was also the objective of this study to determine the timing and duration of supergene alteration. Samples for polished thin sections were carefully selected from eight representative boreholes to be representative of all the lithostratigraphic zones and ore types. The thin sections were used to study mineralogy by means of reflected light microscopy and scanning electron microscopy. X-ray powder diffractometry on representative powder samples were used to study the mineralogy and geochemistry of the samples. Microprobe analyses were also performed on the representative samples. Finally the samples were submitted for 40Ar/39Ar geochronology. In this supergene enrichment zone carbonates are leached (associated with an increase in porosity) and Mn2+/Mn3+ -bearing minerals (kutnahorite, Mn-calcite an braunite) are altered to supergene Mn4+-bearing mineral phases (todorokite and manganomelane) and minor quartz. This process upgrades ore from 38 wt% Mn to ore with more than 40 wt% Mn. Element fluxes, enrichment and depletion of major and trace elements were quantified by mass balance calculations. Na2O, K2O, Sr, Ba, Zn and H2O were enriched, while Mn3O4, Fe2O3, CaO, MgO, P, B and CO2 were leached from the ore during supergene alteration. Results of this study suggest that the development of Post African I erosional surface may have taken place 45 Ma ago. The bottom of the weathering profile gives a well-defined peak at ca. 5 Ma that may possible coincide with the development of Post African II erosional surface. The major characteristics of the alteration process of the unaltered Mamatwan-type ore to supergene altered braunite lutite can be summarized as follow: • Leaching of Mn carbonates and Mn2+/Mn3+-oxides. • Formation of Mn4+-oxyhydroxides and quartz. • Decrease in relative density of the ore. • Increase in porosity of the ore. • Leaching of Mn3O4, Fe2O3, CaO, MgO, P, B, CO2. • Enrichment of Na2O, K2O, Sr, Ba, Zn, H2O. Chemical weathering processes along the Cenozoic Kalahari unconformity appear to have affected the manganiferous lithologies of the Hotazel Formation from 45 Ma onwards to 5 Ma. The weathering front processes very slowly through the Mn-rich braunite lutite (<10m in 40 Ma; <0.25m/Ma); producing a very uniform and microcrystalline supergene mineral assemblage with distinct characteristics.

▼ M.Sc.
Biofuels have the potential to reduce a country’s dependence on imported oil, to ensure diversity of energy sources, to increase the availability of renewable energy sources and to address global environmental issues. In recognition of the potential benefits of the production and use of biofuels, the Department of Minerals and Energy released the Draft Biofuels Industrial Strategy in December 2006 with the aim to increase the use of biofuels in South Africa to replace 4.5% of conventional transport fuels by 2013. However, there are several barriers that need to be overcome before South Africa can establish a large-scale biofuel industry to achieve the DME’s biofuel target. This includes environmental barriers, such as the availability of land for the cultivation of biofuel feedstocks and potential threats to food security. This study focuses on these environmental barriers and aims to determine the potential for bioethanol production from maize in South Africa to 2013. To this purpose, a bioethanol potential model is developed to simulate the potential for bioethanol production from maize in South Africa between 2008 and 2013. The model incorporates four key elements that all impact on the availability of maize for bioethanol production, namely: maize demand; maize supply; the demand for maize as biomaterial; and the available land area for the cultivation of maize. The study makes further use of the scenario planning method to determine the potential for bioethanol production from maize in South Africa. Four unique bioethanol potential scenarios are designed and simulated within the bioethanol potential model developed for this purpose. Each scenario plays out a different Abstract storyline for the future social, economic and natural environment that will impact on the availability of maize for bioethanol production. The results of the bioethanol potential scenario simulations show that South Africa will be able to produce enough maize to meet the DME’s biofuel target of 1.2 billion liters of bioethanol for all scenarios between 2009 and 2010. From 2011 onwards, the bioethanol potential decreases below the DME’s target value in both the worst case and rapid change scenarios. The study concludes that the production of bioethanol from maize in South Africa will have various social, economic and environmental consequences for the country’s agricultural sector. The depletion of domestic maize supplies will seriously threaten food security and consequently, increase the country’s dependence on maize imports. This will not only affect the country’s maize producing regions, but spread throughout South Africa as the demand for agriculturally productive land for maize production increases. Domestic food security is therefore at risk and South Africa will have to resort to other energy technologies to achieve a sustainable and renewable energy future for road transport.

▼ M.Sc.
An estimated 98% of the iron ore exploited in the world is used in the manufacture of pig iron and steel, which are non-substitutable backbones of modern society. The rapid increase of world steel production over the last few years, driven mainly by economic growth in China, have required an equal increase in iron ore production, from 876.8 Mt in 2006 to 948.1 Mt in 2007. The increased rate of exploitation of iron ores has resulted in a rapid depletion of known high-grade iron ore deposits. This, in turn, has led to a dramatic increase of prices, especially for highly thought-after high-grade lumpy iron ores from BIF-hosted deposits. In the absence of any major new discoveries of high-grade iron ore deposits, mining companies have turned to lower-grade materials to assess their beneficiation potential to expand their production base and beneficiation capacity, in order to satisfy future demand. Within this existing framework, this research project was initiated to assess the beneficiation potential of low-grade lumpy stockpiles and high-grade iron ore fines at Beeshoek Iron Ore Mine, owned by Assmang Ltd. The mine is located 7 km West of Postmasburg, in the Northern Cape Province of South-Africa, and processes currently 5.60 million tons of uncontaminated run-of-mine ore per annum. Crushing, washing, classification and jigging are used to produce 2.12 million tons of (37.8% of ROM) of lumpy iron ore product. The balance (3.48 million tons) is currently not used, but is stockpiled or discarded. This includes 0.90 million tons (16.2% of ROM) of ore-grade fines, 0.86 million tons (15% of ROM) of tailings sludge and 1.74 million tons (31% of ROM) of lumpy low grade material. Both ore-grade fines and low-grade lumpy material are discarded separately; they are currently considered as waste. The low-grade lumpy is stockpiled while the fines are used to fill-in mined-out open pits. The evaluation of the beneficiation potential of these two material streams is the main goal of this study. Representative samples were collected from ore-grade fines and the current stockpile for low-grade lumpy material. Hand sorting and lithological categorization of the lumpy material facilitated petrographic and mineralogical studies using light and scanning electron microscopy, as well as X-ray powder diffraction studies. Major and trace element geochemistry were determined using X-ray fluorescence spectrometry and titrimetry (to accurately determine the concentration of iron). Whole rock densities were determined for all lithotypes recognized in the low-grade lumpy material. The grain size distribution was determined for the lumpy materials by actual measurement of the diameter of a representative number of particles, and for fines by sieve analysis. Fines beneficiation tests were conducted using spiral separation and simple classification tests. Washing was used as additional beneficiation method on the fines.

▼ When considering a person's self-esteem, behavioural patterns and personal interactions, the
one feature having the most impact is their physical appearance. In an ideal world, every
person should have a fair opportunity to reach their full potential in life.
Orthodontics can improve a person's quality of life by creating confident smiles and a
functional occlusion (Sheiham, 1993).
Uncorrected malocclusions can adversely affect one's speech, general health and self-esteem.
Improving the general physiological implications malocclusions has on person, may make
them more employable and more successful in relationships, creating an overall happier,
healthier and more successful community. The more people are offered affordable
orthodontic treatment, the more acceptable orthodontic treatment may become. Thus, the
perceived benefits of Orthodontic treatment in a population group are Improvement of Oral
Health and enhancement of psychosocial welfare. Accurate data on the prevalence,
distribution and severity of malocclusion is needed by provincial oral health management.
They also need accurate data of the orthodontic treatment need of the children in that specific
area. This data is vital for the effective planning of the education, training and deployment of
dental workers, as well as the resources and distribution thereof in specific, designated areas
(Holtshousen, 1997; So & Tang, 1993).
This study's focus was to estimate the prevalence of malocclusion amongst adolescents in
Upington area in the
Northern Cape, and to determine the need for orthodontic treatment in
the area using the Index for Orthodontic Treatment Need (IOTN).

▼ The Keimoes Suite is a group of poorly defined granitoids that characterize the Namaqua Front and Foreland zones. There is a lack of knowledge on its content and distribution. A significant amount of work has been done on the geochemical and geochronological aspects of the Keimoes Suite but no structural analysis using a comparison between joint occurrences in the suite and the country rock has been found in the literature. This study provides insight on whether these joints formed as a result of the emplacement and subsequent cooling of the granitoids or whether they are the result of later deformation processes. This was achieved through remote sensing, detailed field mapping and structural analysis of joint data to determine the type of stress regime associated with their deformation. Eleven granitoids of the Keimoes Suite were mapped in the Kakamas-Keimoes area in the
Northern Cape,
South Africa. Up to four joint sets were mapped and characterized according to orientation, abutting relationship, in-filling material and spacing properties. The orientation analysis revealed two prominent joint sets (NNW and NE) that are consistent throughout the Keimoes Suite granite. However after careful analysis of their abutting relationship it has been concluded that these joints are the youngest joints formed in the Keimoes Suite. The fourth set is the E-W set which does not occur at a wide spread scale. The oldest joint set (NNE) is defined by the quartz and feldspar filling and these joints only occur in the oldest granite of the suite. Field observation revealed shear displacement, forming a conjugate joint set. This conjugate set closes at an acute angle of 60˚ and the joints displace each other. The presence of en echelon sigmoidal veins suggests these joints formed as mode II fractures and that they are tectonic joints. The dominant joint set NNW is parallel to the regional foliation, shear zones and faults which were formed during the D2 deformational vent of the Namaqua Orogeny. This NNW joint set post-dates the D2 deformational event and was formed during the D3 deformational environment of the Namaqua Orogeny. Principal stress analysis of all the joints in the study area suggests a strike-slip environment, which coincides with the D3 deformation event of the Namaqua Natal Province. Even though the country rock and the Keimoes Suite granites were subjected to same stress field during the D3 event, the analysis of principal stresses between the Keimoes Suite granites and the country rock reveals a slight difference in the orientation of the principal stresses. This is caused by the
difference in competency between the Keimoes Suite granites and the country
rock thus caused the refraction. In conclusion Structural evidence on various members of the Keimoes Suite indicates three episodes of intrusions with respect to the D2 Namaqua deformation event based on foliation and mineral filled joints. The Vaalputs
Granite is pre tectonic relative to the main D2 deformation event and the thermal
peak M2 metamorphisms, while…

▼ The Makganyene Formation forms the base of the Postmasburg Group in the
Transvaal Supergroup in the Griqualand West Basin. It consists of diamictites, sandstones,
banded iron-formations (BIFs), shales, siltstones and carbonates. It is generally accepted that
the Makganyene Formation rests on an erosive regional unconformity throughout the
Northern Cape Province. However this study demonstrates that this stratigraphic relationship
is not universal, and conformable contacts have been observed. One of the principal aims of
this study is to identify the nature of the Makganyene basal contact throughout the Griqualand
West Basin.
Intensive fieldwork was carried out from Prieska in the
south, to Danielskuil in the
north. In the Sishen and Hotazel areas, only borehole material was available to assess the
stratigraphy. The Griquatown Fault Zone delimits the boundary between the deep basin and
platform facies. The Koegas Subgroup is only present
south of the Griquatown Fault Zone,
where it pinches out. However, the transition Griquatown BIFs-Koegas Subgroup occurs in
lacustrine deposits on the Ghaap platform (Beukes, 1983). The Griquatown Fault Zone
represents the edge of the basin, which corresponds to a hinge rather than a fault zone. The
Makganyene Formation rests with a conformable contact on the Koegas Subgroup
south of
the Griquatown Hinge Zone, and north of it the Makganyene Formation lies unconformably
on the Asbestos Hills Subgroup.
The Makganyene Formation displays lateral facies changes that reflect the
paleogeography of the Griqualand West Basin, and the development of ice sheets/shelves.
The Ghaap platform is characterised by coarse immature sand interbedded with the
diamictites. The clasts in this area contain local Asbestos Hills material and no dropstones are
present. Such settings are typical of sediments that are being deposited below a grounded ice
mass. At the Griquatown Hinge Zone, the sandstone lenses are smaller, and the clasts consist
of chert, of which a great number are striated and faceted. In the Matsap area, the presence of
dropstones is strong evidence for the presence of a floating ice shelf that released its material
by basal melting. Further
south, the Makganyene Formation contains stromatolitic bioherms
that only form if clastic contamination is minimal and therefore the ice that transported the
detritus to the basin did not extend far into open sea conditions. The base of the Hotazel Formation also contains diamictite levels. Dropstones have
been identified, implying a glacial origin. The Hotazel diamictites are interbedded with
hyaloclastites and BIFs. The Makganyene glacial event, therefore, was not restricted to the
Makganyene Formation, but also included the Ongeluk Formation, through to the base of the
Hotazel Formation.
Petrographic studies of the Makganyene Formation and the base of the Hotazel
Formation reveal mineral assemblages that are diagnostic of early to late diagenetic
crystallisation and of low-grade metamorphism not exceeding the very low green-schist
facies. The facies…

▼ The commercial mining of asbestos occurred in four Provinces of
South Africa
(
Northern Cape, North West, Limpopo and Mpumalanga). It was initiated in the
late 1800's and lasted for over a hundred years into the beginning of this century.
As a producer of amphibole asbestos,
South Africa far outpaced every other
country being responsible for 97% of global production. The last crocidolite mine
closed in 1996 and chrysotile in 2002. Anecdotal information concerning
environmental contamination as a result of the former mining activities and the
improper disposal of mine waste tailings has been reported by a variety of authors.
Few comprehensive or systematic surveys have been conducted to date to
document this issue and very little quantifiable research has been completed on
the communities located in close proximity to the former mine sites to determine
the extent of contamination. In 2004-2006 communities were surveyed within the
Northern Cape and North West Provinces to determine the extent and severity of
environmental contamination. This research developed and applied a
methodology to select those communities suspected of environmental
contamination, a targeted survey methodology, and a protocol for rapid sample
laboratory analysis. A total of 41 communities were initially predicted by the model
to be suspected for environmental asbestos contamination. Based on the inclusion
of local knowledge, a final 36 communities were selected for a screening-level field
assessment, 34 of which were found to contain environmental asbestos
contamination at rates ranging from 20 to 100% of the surveyed locations. A total
of 1 843 samples of soil and building material were collected in the screening level
assessment. One community (Ga-Mopedi) was selected as being representative
of the total cohort and a more detailed house to house survey was completed. A
total of 1 486 samples were collected during the detailed survey. Results of the
detailed survey revealed 26.2% of the homes were contaminated with asbestos
containing soil and/or building material. A theoretical quantitative cumulative
exposure assessment was developed to estimate the disease burden within the
study area population of 126,130 individuals within the surveyed communities
resulting in a predicted range of 25-52.4 excess deaths per year from lung cancer
and mesothelioma due solely to environmental exposures to asbestos pollution.

▼ ENGLISH ABSTRACT: Internal migration in post-apartheid
South Africa is the primary focus of this dissertation. The geographic focus is on two of the country’s current provinces. In both the
Northern Cape and the Western
Cape provinces, apartheid policies that restricted the free movement of certain
South Africans were supplemented by further restrictions arising from the policy of Coloured Labour Preference. It is because of these legislative constraints that resulted in a distortion and interference of migratory waves and trends that these two provinces offer a unique opportunity to do systematic research. Accordingly, the study identifies and analyses the primary changes in the direction and nature of internal migration streams into and within these provinces subsequent to the end of the apartheid regime and scrapping of such restrictive policies.
Method: The main demographic and locational characteristics used in this analysis are changes in the size of the overall migration streams, their shifting mix of population groups (Black African, Coloured, Indian/Asian and White), the age of migrants, and the urban, peri-urban or rural nature of these migrants’ destinations. Migration data from three post-apartheid periods - 1996-2001, 2001-2006 and 2006-2011 – are analysed so as to enable comparisons of migrant flows between each of these periods.
Findings: Comparing the net-migration rates during the earlier and latter post apartheid periods, both provinces reveal a deceleration in general mobility and in urbanisation, suggesting a slowing down in net migration flows in the latter period. Measuring and describing how migrants in these two provinces move, data pertaining to both inter-provincial migration (movement across provincial boundaries) and intra-provincial migration (movement within provincial boundaries but across municipal district boundaries) are considered. Although some variation in movement is illustrated for the two provinces, the data clearly illustrates continuing urbanisation in the settlement patterns of migrants for both migration flows. Considering the characteristics of migrants, the data illustrated migrants as mostly mature adults (30-60 years of age), except for in-migrants to the Western
Cape who are mostly younger adults (20-29 years of age). The Black African population is the most mobile within inter-provincial migration streams, with the Coloured population the most active in intra-provincial flows. When comparing pre- and post-1994 internal migration trends in the two provinces, the dissertation illuminates three specific shifts, (i) a change in the political context within which mobility is framed, (ii) a change in the type of internal migration flows that are sustaining urbanisation and, (iii) a change in the profile, specifically pertaining to population group, of migrants mobile in the two provinces. The dissertation concludes by making a case for the adoption of a strategic and concerted approach by governments to accommodate the developmental constraints and challenges posed by…

▼ ENGLISH ABSTRACT: “… wood carved by the knife of circumstance…”?: Cape Rapists and Rape in South Africa, c. 1910-1980, interrogates the notion that rapists are a product of an inherent nature and/or are nurtured by their environments to commit acts of rape. It also attempts to contextualise the changing definitions, motivations, justifications, and rationalisations given by theorists, politicians, jurists, the medical profession, society, communities, families, rape victims, and rapists. The central thesis questions, a slight adaptation from that of Joanna Bourke, are: “who were the rapists in the Cape?”, “why did they do what they did?” and “how particular are they to the Cape?” By contextualizing existing studies on rape with the accounts within the rich primary archives, Cape rapists are not merely located, defined, and explained, but are also contextualized within broader South African and global categories of rapists in what unfolds as a history of contested (and sometimes competing) notions of consensual sex, sexuality, and non-consensual sexual violence.
DUTCH ABSTRACT: ‘Houtsnijwerk, het mes of de omstandigheden als gereedschap?’ Verkrachters in de Kaap en verkrachting in Zuid-Afrika, circa 1910-1980, onderzoekt niet alleen het idee dat verkrachters het product zijn van hun inherente natuur of gevormd zijn door omstandigheden, maar poogt de veranderende definities, motieven, rechtvaardigingen en rationalisaties, opgeworpen door theoretici, politici, juristen, de medische wereld, de samenleving, gemeenschappen, families, slachtoffers en daders in perspectief te plaatsen. De centrale vraagstelling, die licht afwijkt van de vraagstelling van Joanna Bourke, cirkelt rond de vragen: ‘Wie waren de verkrachters in de Kaap?’, ‘Waarom deden zij wat ze deden?’ en ‘Zijn deze gevallen exemplarisch voor de Kaap?’ Door bestaande studies over verkrachting te voorzien van een context, met behulp van beschrijvingen die terug te vinden zijn in archieven, kunnen verkrachters uit de Kaap niet alleen worden gelokaliseerd, gedefinieerd en geduid, maar tevens gecontextualiseerd binnen het bredere verband van Zuid-Afrikaanse en wereldwijde categorieën van verkrachters, in wat zich ontvouwt als een geschiedenis van betwiste (en soms rivaliserende) ideeën over consensuele seks, seksualiteit en non-consensuele seks.
AFRIKAANSE OPSOMMING: “…hout gekerf deur die mes van omstandigheid…”?: Kaapse Verkragters en Verkragting in Suid-Afrika, c. 1910-1980, ondersoek die idee dat verkragters of ’n produk is van ’n inherente of aangebore aard, en/of dat hulle deur hulle omgewing gevorm word om dade van verkragtig te pleeg.

▼ In the Upington region, there are three major- tectonic crustal provinces; namely the Kaapvaal Craton, Kheis and Namaqua tectonic provinces. The Eburnian-aged (early Proterozoic) Kheis Province developed along the western flank of the Archaean Kaapvaal Craton while the Kibaran-aged (middle Proterozoic) Namaqua Metamorphic Province, superimposed on the Eburnian-aged basement, developed to the east of the Kheis Province. The Namaqua Metamorphic Province is divided into the Gordonia and Bushmanland Subprovinces, the former being further subdivided into various tectonostratigraphic terranes. These are termed, from west to east, the Kakamas, Areachap, and Upington Terranes. The Upington Terrane includes fault bounded grabens with accompanied bimodal volcanism and sedimentation of the Wilgenhoutsdrif and Koras Groups. The Areachap Terrane consists predominantly of amphibolites generated in an island arc environment while the Kakamas Terrane is characterised by volcano-sedimentary sequences which have been extensively intruded by syn to late-tectonic predominantly I-type Keimoes Suite granitoids. The main styles of mineralisation correlate well with the various tectonostratigraphic terranes. Sedimentary exhalative massive sulphide deposits are characteristic of the Bushmanland Subprovince and are thought to be associated with the deposits at Aggeneys and Putsberg to the west of the area under investigation. These deposits are considered to have been deposited in an east-west-elongated intracontinental basin. The Kakamas Terrane is typified by granite-related mineralisation. In the eastern portion of the Kakamas Terrane, Sn-Wand base metal-bearing veins occur while pegmatites are developed in the western portion. These two styles of granite-related mineralisation is considered to reflect differing depths of formation due mainly to varying degrees of thrusting. The Areachap Terrane consists of volcanogenic massive sulphide deposits of the Besshi-type and is considered to have formed in a back-arc environment. In the Upington Terrane, the Wilgenhoutsdrif and Koras Groups consists essentially of minor Cu occurrences mainly disseminated within basalts and in structural trap sites. The possibility for sediment-hosted Cu deposits is not ruled out. More recent surface processes have led to uranium and gypsum deposits in pans, river beds and calcretes. Eburnian aged tectonic setting remains enigmatic. Kibaran-aged tectonics which best fits the metallogeny of the area under investigation is considered to be of a subduction zone from west to east formed by the collision of the Bushmanland "microcontinent" against the Kaapvaal Craton. Subduction fbrmed an island arc setting in which the massive sulphide deposits were formed in the Areachap Terrane while the Wilgenhoutsdrif Groups developed in a marginal basin. Further convergence led to collision of the two continents and underriding of the Bushmanland "microcontinent" which generated predominantly I-type granitoids represented by the Keimoes Suite. The level of emplacement of these…

▼ The Makganyene Formation forms the base of the Postmasburg Group in the Transvaal Supergroup of the Northern Cape Province. The Makganyene Formation has diamictite as the main rock type, but siltstone, sandstone, shale, and iron-formations are also present. A glacial origin has been proposed in the past due to the presence of dropstones, faceted and striated pebbles. Typically, the Makganyene Formation contains banded iron-formations interbedded with clastic rocks (shale, siltstone, sandstone and diamictites) at the contact with the underlying iron-formations. This transitional zone is generally overlain by massive or layered diamictites which contain poorly sorted clasts (mainly chert) within a shaly matrix. Striated pebbles have been found during field work, and dropstones have been observed in diamictites and banded iron-formations during the study. The top of the Makganyene Formation contains graded cycles interbedded with diamictites and thin layers of andesitic lavas from the Ongeluk Formation. The basal contact of the Makganyene Formation with the underlying Koegas Subgroup was described as unconformable by previous workers. However field work localised in the Rooinekke area shows a broadly conformable and interbedded contact with the underlying Koegas Subgroup. As described above, banded iron-formations are interbedded with the clastic rocks of the Makganyene Formation. Moreover, boreholes from the Sishen area display the same interbedding at the base of the Makganyene Formation. This suggests that no significant time gap is present in the whole succession between the Ghaap and Postmasburg Group. The Transvaal Supergroup in the Northern Cape displays the following succession : carbonates-BIFs-diamictites/ lava-BIFs-carbonates. The Makganyene Formation is thus at the centre of a symmetrical lithologic succession. Bulk rock compositions show that the diamictites have a similar composition to banded iron-formation with regard to their major element contents. Banded iron-formations acted as a source for the diamictites with carbonates and igneous rocks representing minor components. Differences in bulk composition between the Sishen and Matsap areas emphasize that the source of the diamictite was very localised. The Chemical Index of Alteration (CIA) has been calculated, but since the source dominant rock was iron-formation, this index cannot be usefully applied to the diamictites. ACN, A-CN-K, and A-CNK-FM diagrams confer a major importance in sorting processes due to the separation between the fine and coarse diamictites. The interbedded iron-formations display little clastic contamination indicating deposition in clear water conditions. However, dropstones are present in one borehole from the Matsap area, indicating that iron-formation took place under ice cover, or at least under icebergs. Stable isotope studies show that the iron-formations, interbedded towards the base of the Makganyene Formation, have similar values to the iron-formations of the Koegas Subgroup. As a result of the above observations, new…

▼ ENGLISH ABSTRACT: The north-western region of the Western Cape forms part of the Fynbos biome and is home to the indigenous plant, A. linearis (rooibos). Rooibos cultivation is restricted to a small geographic area with wild rooibos plants being more at risk as a result of climate change. This research contributes to a growing body of evidence of the impacts observed and experienced by small-scale farmers, by adding much-needed analysis of empirical data on rooibos under low precipitation conditions to the body of science. The overall aim of this study was to examine the physiological response, using xylem hydraulic conductivity, to drought stress of wild and cultivated A. linearis plants in the Suid Bokkeveld and to determine the effects of organic mulch on cultivated rooibos‘ susceptibility to xylem cavitation in response to drought stress. The information was used to compare farmer perceptions of rooibos drought responses and to spotlight the variations and similarities between the two information systems (scientific and local ecological knowledge) with the hope of providing guidelines for effective climate change adaptation strategies. A. linearis appears to respond to soil moisture gradients but showed little differences within sites according to the reseeder-resprouter dichotomy. On the other hand, the use of mulch did not have an impact on the cultivated rooibos‘ hydraulic characteristics. Cultivated (reseeding) and wild (resprouting) rooibos ecotypes may differ in terms of their physiology, however, when the effects of drought exceed levels of tolerance in the two ecotypes, according to responses from the questionnaire survey, both may exhibit similar strategies (branch sacrifice and red leaf discoloration) to cope with prolonged precipitation deficits. The quarterly climate change workshops have proven to be a helpful tool when it comes to incorporating local climate issues with that of seasonal forecasts and ultimately provides a platform for adapting new methods in addressing the impacts of drought and climate change. Results from the traditional scientific methods and the survey questionnaire on local knowledge show that there may exist important disparities between these two methodologies, however, each prove invaluable for understanding certain phenomena exhibited, in this case, by wild and cultivated rooibos ecotypes. Local knowledge should be used to emphasize problem areas and detect possible solutions whereas conventional scientific methodologies may often assist in converting potential problems into a broader range of appropriate hypothesis testing.
