- Description: The use of Information Communication Technologies (ICTs) can support sustainable development within societies. ICTs have been supported by governments, private companies, non-governmental organisations, academic institutions and individuals. However, technological changes have made most ICT initiatives haphazard due to poor planning. There is no systematic plan on how to deploy services, infrastructure and devices especially in rural areas. For instance, in some cases, computers have been donated to communities in rural areas yet they are not being used, and ICT services have been deployed without the supporting ICT infrastructure. One of the solutions to addressing these ICT challenges is through the use of roadmaps to guide ICT solution implementation. This thesis proposes an ICT roadmap methodological framework to improve ICT roadmap development for rural ICT solutions. A composite methodological approach was employed in this research. This involves the use of qualitative research techniques such as participant observation, design exercises, workshops, focus groups and individual interviews supported by ethnographic studies. The Siyakhula Living Lab in the Eastern Cape Province of South Africa was used as the case study. Studies were conducted to identify the current state of ICTs in rural areas, the future of ICTs and overview of roadmap developments. Rural users in South Africa, ICT experts in Europe and Africa, government officials and academic institutions were engaged to understand the current ICT planning, developments and needs. The author found that there are variations in individual ICT services required by rural users but, most ICT services in need fall mainly in the areas of health, education, entrepreneurship, agriculture and employment creation for rural people. These services require ICT devices and infrastructure which include computer peripherals, mobile phones, radios, televisions and wireless infrastructure, mobile infrastructure, satellites and broadcasting infrastructure respectively. It was found that the common future ICT projections expected in rural areas include: growth of mobile usage, social networking, increase internet services and localization of services. The roadmap framework is built based on the current state of ICTs, trends in ICTs, future technological projections and the plans currently been initiated in African continent. The ICT roadmap methodological focuses on how roadmaps could accommodate infrastructure, services and ICT devices to reach rural people. This should help rural users to be able to access public services within their respective communities using available ICT devices. ICT stakeholders could use the designed framework to improve the ICT roadmap development process for rural ICT users in Africa.

- Description: The adoption of the Millennium Development Goal 1 (MDG1) of reducing the rate of poverty to half of the 1990-level by 2015, the advent of democracy in South Africa, among other things, have raised concerns over the potential role of the agricultural sector. There is a belief that the sector has the capacity to successfully reduce poverty among the rural masses and contribute to addressing the problem of inequality in South Africa. In line with that thinking, South Africa‘s agricultural sector has attracted considerable fiscal policy interest. For instance, South Africa‘s statistics show that public investments in agricultural development programmes have been growing. In spite of this, rural poverty is still a major concern on an overall basis. However, this might not be the case in the Eastern Cape Province and the situation might be different for each district municipality. This study assesses the linkages between public agricultural investment, agricultural growth and poverty reduction in the Eastern Cape Province. The study also addresses the question whether Eastern Cape Province is on course to meet several regional development targets. The study also aims to provide an estimate of the amount of agricultural investment required to attain the agricultural productivity growth rate which is sufficient to meet MDG1. The study reviewed the various theories of public spending, linkages between public investment and agricultural growth and how these components affect the incidence of poverty. The conventional wisdom that public expenditure in agriculture positively affects economic growth and this growth consequently reduces poverty was noted. The reviews also revealed that in many developing countries, the current level of public agricultural investment needs to be increased significantly for countries to meet the MDG1. This study employed the decomposition technique and growth elasticity of poverty concept to estimate the response of poverty to its key determinants. The size of public spending, prioritization of public spending and the intensity in the use of public funds emerged as important in increasing agricultural production. The relationship between government investment in agriculture and agricultural GDP shows iv that public funds were largely behind the province‘s success in increasing agricultural production throughout the period from 1990s to 2010. Agricultural spending went to sustainable resource management, administrative functions and then farmer support programme. Exceptional growth in the size of spending was recorded in respect to agricultural economic function, structured agricultural training, sustainable resource management and veterinary services. Overall output from the agricultural sector fluctuated, and the sector contributed less than 5 per cent to the total provincial GDP. Correlations between growth in agricultural sector and changes in the incidence of poverty in Eastern Cape show that during the period 1995 to 2000, increases in the agricultural GDP per capita may have failed to benefit the poor as poverty increased in all the reported cases.–However, for the period between 2005 and 2010, the situation was different and it was observed that increases in agricultural GDP per capita and were associated with reduction in the incidence of poverty. Growth elasticity of poverty (GEP) estimates reveal that agricultural GDP per capita was more important in reducing poverty in 5 out of the 7 district municipalities. Non-agricultural GDP per capita was only important in two district municipalities. It emerged that most of the district municipalities are not in a position to meet any of the regional set goals. This situation is largely attributable to the province‘s failure to boost agricultural production which is an outcome of low and inefficient public expenditure management, inconsistent and misaligned policies and failure to fully embrace the concept of pro-poor growth. Varied provisional estimates for the required agricultural growth rate and the increase in public spending on agriculture required in order to reach MDG1 were calculated for each district municipalities. All the district municipalities of Eastern Cape will need to increase public investment in agriculture for them to achieve MDG1.

- Description: It has become commonplace in academic studies, particularly those with a critical bent, to view nations as being historical constructs, as being without essence, though not without effects of exclusion and inclusion, of the constitution of the „authentic‟ national subject and the „other of the nation.‟ The critical impetus at work here is to show how a nation is constructed in order to bring into view the knowledge and power relations this construction entails, to show whose interests the construction serves, and whose it does not. This study examines the discursive production, the performative enactment and the spatial emplacement of post-apartheid „South Africanness‟ through a case study of Oppikoppi music festival. Oppikoppi is an annual event that emerged in 1994, on the threshold of the „new South Africa.‟ The festival is attended predominantly by young white Afrikaans-speaking South Africans and is held on a farm in the northernmost province of Limpopo, South Africa, an area notoriously conservative in its racial politics. Yet, curiously, Oppikoppi has been repeatedly referred to, and refers to itself with an almost obsessive regularity and repetitiveness, as a „truly South African‟ event. Indeed, the festival has been promoted, since 1998, as „The Home of South African Music,‟ and in 2009 the site of the festival was unofficially declared a „national monument.‟ Through the employment of concepts drawn from the writings of French philosopher and historian, Michel Foucault – particularly his earlier archaeological works – and from Sigmund Freud – particularly his metapsychological works – this study has posed two broad sets of questions. Firstly, from a Foucauldian perspective, what have been the conditions for the production of „South Africanness‟ at this festival? What have been the requirements, the discursive „rules of the game‟ for whiteness and Afrikanerness to become „South African‟? To what extent does this constitution of the festival as a „South African‟ event preserve older lines of division, difference and oppression? To what extent does this bring about meaningful social change? Secondly, from a psychoanalytic perspective, what are the fantasies constellated in the discourse of the festival as a „South African‟ event? Who, in these fantasies, is constituted as the „other of the post-apartheid nation‟? How has fantasy provided a kind of „hallucinatory gratification,‟ a phantasmatic compensation for, and a means of conserving, the losses of privilege in the new nation? And how has fantasy oriented the festival towards post-apartheid sociality, soliciting identifications with the post-apartheid nation? The overarching argument proposed is that anti-apartheid post-apartheid nation building has cultivated a melancholic loss of apartheid for whites in general and Afrikaners in particular, a loss that cannot be grieved – indeed, a loss that should not be grieved – and, as such, a grief that takes on an unconscious afterlife. Apartheid and the life it enabled – not only racialised privilege, but also a structure of identification and idealisation, of being and having – becomes a loss that is buried in, and by, the injunctions issued to post-apartheid memory and conduct. Without the discursive resources with which to symbolise this loss, disguised repetitions of the past, a neurotic refinding of the lost objects of apartheid, and melancholia are the likely outcomes, each of which engender a set of exclusions and enjoyments that run along old and new lines.

An evaluation of women participation in housing delivery in the Eastern Cape Province of South Africa: the case of the Mdantsane Township in Buffalo City Municipality (1962–2012)

- Description: This study, Women Participation in Housing Delivery of the Mdantsane Township Buffalo City Metropolitan Municipality (BCMM) Area is explained in this thesis as a heterogeneous, long lasting, immobile and an essential consumer good that need to be delivered to the homeless. Such a delivery process needs to ensure that the Buffalo City Metropolitan Municipality area remains sustainable. Women's participation in housing delivery in South Africa; the extent of empowerment in the post 1994 era, with specific reference to case studies in Mdantsane Township 1962 -1998, begins with the premise that post-apartheid housing policies, compared to those of the apartheid era, have provided women with greater access to housing. In 1994, the housing backlog was estimated to be about 3.5 million units, with the majority of those in need of shelter, being African women. This backlog was due to past policies that largely excluded women from ownership and access to capital or resources to build formal housing. The changes wrought by the democratic dispensation, such as constitutional provision for gender equality, promised women greater participation in the social, political and economic spheres of the country. The recognition of gender equality and housing as rights protected within the constitution was reinforced by pronouncements in various policy documents, such as the Housing White Paper (HWP) that underlined the need for women's involvement in shelter development. When the Government of National Unity took office in 1994, it inherited a country with severe inequalities in resource distribution and land ownership. In particular, it inherited a housing crisis, which was largely, caused by apartheid legislation and policies. This research focused on the women participation in the housing delivery crisis from 1962 to post-1994, by considering the impact and effect of the constitutional right towards women to have access to adequate housing, especially for those living in intolerable conditions. It does so by utilising a social-scientific approach to the law. This approach acknowledges that the housing right must exist alongside other social phenomena and as a part of everyday life in South Africa. Accordingly, the implementation of the housing right by three local municipalities in the EC was examined.

- Description: The essential function of a language is communication. Effective communication takes place when speakers understand each other‟s language. Speakers of different languages these days stay with each other. This kind of setting results into multilingualism. Multilingualism refers to the use or maintenance of more than one language in a certain context. In this regard it may refer to the fact that many languages are spoken in South Africa. It serves as a natural solution to the problem of language contact that is extremely widespread throughout South Africa and the world at large. The recognition of the multilingual nature of South African society by the Constitution of this country , as (Made 2010) puts it, necessitates the creation of tools of implementation and redress, in the form of appropriate language policies. Such language policies are designed to correct the universal tendency to practise monolingualism in multilingual societies which disempowers non-mother tongue speakers of the dominant language, to the detriment of both their rights as citizens and in communicative equity in exercising these rights. Many Black South Africans took employment in the industrial centres through urbanization, where they learnt many languages such as Fanakalo, English, Afrikaans and many other languages in the African continent. This resulted into linguistic heterogeneity. Heterogeneity brings speakers of languages together at different workplaces, schools and even places of abode.

- Description: The purpose of this study was an investigation of the reasons for persistent poverty and low level of economic growth and development in the OR Tambo district municipality of the Eastern Cape Province since the advent of democracy in South Africa. To accomplish this objective, a case study of the OR Tambo district municipality was undertaken within the concept of development, seeking to answer three research questions: What are the factors that explain the persistence of poverty in the OR Tambo district municipality? Why is the OR Tambo district municipality the most exposed to poverty in relative and absolute terms? What have state poverty intervention strategies done to alleviate poverty in the OR Tambo district since the advent of democracy in South Africa? Mainly qualitative data collection methods, involving in-depth semi-structured interviews, textual and document analyses, focus group discussions and observations were employed to answer the research questions. A purposive sampling of nineteen participants, supplemented by three focus groups, was selected. The macro-level case study design was supplemented by micro-level documentary evidence on poverty and development. From the synthesised findings of the investigation, twelve causal factors were identified as responsible for persistent poverty and low level of economic growth and development in the OR Tambo district. These included political neglect, agricultural neglect, poor infrastructure, corruption, poor service delivery, poor quality of natural resources, brain drain, migrant labour system, culture of tolerance and conservatism, culture of dependence, no long-term development strategy and globalisation.

- Description: In Zimbabwe, translation studies is yet to be recognized as a discipline worthy of study in its own right, hence, not much research has been carried out into the theory and practice of translation. Furthermore, there is no tertiary institution that offers professional translation courses. In light of this information most translations are carried out by untrained/partially trained translators with only a few translators who have gained experience over time. The aim of this study was to investigate strategies used by Ndebele translators in the translation of specialized terms and cultural taboos in selected HIV/AIDS texts, as well as factors that can be used to improve the translation situation of Zimbabwe. Three main theoretical approaches were used in a complementary fashion, namely Descriptive Translation Studies (DTS), Cultural Studies and Corpus-based Translation Studies (CTS). DTS provided the researcher with a theory to understand the Ndebele translations in their wider environment; Cultural Studies provided the researcher with the means by which to understand Ndebele culture and taboos; Corpus-based Translation Studies (CTS) provided the researcher with the methodological tools and analytical techniques to analyse the corpus of texts. An English-Ndebele Parallel Corpus (ENPC) was created using fourteen English source texts and their corresponding Ndebele translations. The ENPC was interrogated by means of ParaConc, a parallel concordancing program. The study found that when translating specialised terms, Ndebele translators used strategies such as a general or neutral word, cultural substitution, paraphrasing and omission. The strategy of omission was misused in most cases because Ndebele translators omitted valuable information which did not reach the target readers. With regards to translation strategies that contributed to term creation, it was found that Ndebele translators relied on external as well as internal resources. The translators used strategies such as pure loan words; pure loan words preceeded by an explanation and indigenised loan words. From the Ndebele language itself, the translators resorted to semantic shift, compounding, coinage and paraphrasing, among others. From the ENPC it is clear that Ndebele translators did manage to transfer the message from English to Ndebele to an extent. However, the ENPC has to be used with caution by other researchers since the translations included in the corpus are full of errors such as misinterpretations of the source texts, mistranslations, incorrect terms and incorrect orthography. This factor points to a dire need to establish translation as an academic discipline and profession in Zimbabwe so as to elevate the quality of translations and offer better translation services to all users.

- Description: Infection with Helicobacter pylori has been associated with the pathogenesis of numerous stomach and gastroduodenal diseases that pose threats to public health. Eradicaftion of this pathogen is a global challenge due to its alarming rate of multidrug resistance. Consequently, to find an alternative treatment, the search is increasingly focused on new antimicrobial product from natural sources including honey. Honey has been used as medicine in several cultures since ancient time due to its enormous biomedical activities. Its beneficial qualities have been endorsed to its antimicrobial, antioxidant, anti-inflammatory properties added to its phytocomponents. In this study, the anti-H. pylori activity of South African honeys and their solvent extracts as well as the phytochemicals present in the two most active honeys were evaluated. Agar well diffusion test was used to investigate the antimicrobial activity of six honey varieties obtained from different locations in the country. Subsequently, the honeys were extracted with four organic solvents viz n-hexane, diethyl ether, chloroform and ethyl acetate employed in order of increasing polarity. The antibacterial activity of the different solvent extracts of each honey was evaluated by agar well diffusion; broth micro dilution and time kill assays. Different chromatographic techniques (Thin layer & column chromatography) were employed to enumerate the phytochemical constituents in the most active solvent extracts of Pure Honey (PH) and Champagne Royal Train (CRT); and were identified by gas-chromatography linked mass-spectrometry. Linalool pure compound was equally evaluated for anti-H. pylori activity in a bid to trace the antibacterial agent among the variety of compounds identified. Data were analyzed by One-way ANOVA test at 95% confidence interval. Crude honeys and their solvent extracts demonstrated potent anti-H. pylori activity with zone diameter that ranged from [16.0mm (crude) to 22.2mm (extract)] and percentage susceptibilities of test isolates between 73.3% (crude) and 93.3% (extract). The chloroform extracts of PH and CRT were most active with MIC50 in the ranges 0.01- viii 10%v/v and 0.625-10%v/v respectively, not significantly different from amoxicillin (P> 0.05); and efficient bactericidal activity (100% bacterial cells killed) at 1/2MIC and 4xMIC over different time intervals, 36-72hrs and 18-72hrs respectively. The appearance of bands on the thin layer chromatography (TLC) chromatogram spotted with the chloroform extracts of PH and CRT; and developed with hexane: ethyl acetate: acetic acid (HEA) and methanol: acetic acid: water (MAAW) solvent systems indicated the presence of compounds. Purification of the compounds contained in these extracts over silica gel column yielded numerous fractions which were evaluated for antibacterial activity and purity. PHF5 was the most active fraction with a mean MIC50 value of 1.25mg/mL. Volatile compounds belonging to different known chemical families in honey were identified in all the active fractions obtained from PH. Conversely, only four compounds were identified in the active fractions obtained from CRT hence the non volatile constituents could be of prime relevance with respect to antibacterial activity of this honey. Of novelty was the presence of thiophene and N-methyl-D3-azirdine compounds, essential precursors used for the synthesis of natural products and pharmaceuticals with vital biomedical properties. Linalool demonstrated potent inhibitory (MIC95, 0.002- 0.0313mg/mL) and bactericidal activity (0.0039-0.313mg/mL) against the test isolates. On the other hand, a significant difference was recorded (P < 0.05) in comparing the activity of linalool compound to the fractions. PH could serve as a good economic source of bioactive compounds which could be employed as template for the synthesis of novel anti-H. pylori drugs. However, further studies are needed to determine the non volatile active ingredients in PH and CRT as well as toxicological testing

- Description: Discovery of cheap, nontoxic and readily available antiatherosclerotic drugs is an extraordinary challenge in this modern world. Atherosclerosis and cardiovascular diseases have been predicted to be the leading cause of death by the year 2030. Hence, this thesis was designed to search for plant (s) with anti-atherogenic properties, investigate its possible side effects and extrapolate its likely mechanism(s) of action. An ethnobotanical survey was employed in identification of locally important plants used for the management and treatment of cardiovascular diseases and its predisposing factors in Nkonkobe Municipality, Eastern Cape in South Africa. Information on the names of plants, their parts used and methods of preparation was collected through a questionnaire which was administered to herbalists, traditional healers and rural dwellers. The most frequently used plant (Rhizomes of Tulbaghia violacea Harv.) was investigated for toxicity using brine shrimp lethality (in vitro) and in vivo toxicity test (acute and subchronic) on rats to determine safety dosage. The in vitro antioxidant and free radical scavenging activity of the plant was investigated using models such as 1,1-diphenyl-2- picrylhydrazyl (DPPH), superoxide anions, hydrogen peroxide (H2O2), nitric oxide (NO), 2,2’- azinobis [3-ethylbenzothiazoline-6-sulfonic acid] diammonium salt (ABTS), lipid peroxidation inhibition and the ferric reducing agent. Phytochemical content and the effect of oral administration of fresh methanolic extract rhizomes of Tulbaghia violacea (250, 500 mg/kg. bwt/day) on Lipid peroxidation (TBARS), serum and tissue antioxidant enzymes in normal, hypercholesterolemic and diet induced atherogenic rats were also assessed. More so, the potential of the extract (250 and 500 mg/kg. bwt) to protect against atherogenic diet (4 percentage cholesterol 1 pecentage cholic acid and 0.5 percentage thiouracil) induced fatty streaks formation, dyslipidemia, oxidative stress and endothelial dysfunction was also investigated. Ethnobotanical study revealed that 19 plant species are used for the treatment of heart related diseases in the Municipality. 53 percentage of the plants mentioned were used for the management of chest pain, 47 percentage for high blood pressure, 42 percent for heart disease, 16 percentage for stroke and 11 percentage for the treatment of hypercholesterolemia. Tulbaghia violacea was repeatedly mentioned as the plant species used for the treatment of high blood pressure and predisposing factors in the study area. The brine shrimp cytotoxicity test revealed that fresh, dried methanolic extracts and essential oil of the T. violacea exhibited a high degree of cytotoxic activity with IC50 values of 18.18 (fresh) and 19.24 (dried) μg/ml. An IC50 value of 12. 59 μg/ml was obtained for the essential oil of the plant. The low cytotoxicity values obtained, suggested that rhizome of T. violacea may serve as a potential source of antimicrobial and anticancer agents. In vivo acute study of single oral administration of 5g/kg dose does not produce mortality or significant behavioral changes during 14 days observation. In the sub-chronic study, the extract (250, 500 mg/kg/bwt/ day) administered for a period of 28 days showed no mortality or morbidity. The weekly body and organ weight of the rats showed no significant differences between the control and the rats treated with the extract. The extract at all doses does not show any effect on of biomarkers of liver or renal damage. However, a significant decrease in the activity of ƔGT was observed in the extract treated groups. Hematological evaluation revealed that oral administration of fresh methanolic extracts of rhizomes of T. violacea does not cause anaemia or leucocytosis in the animals. Furthermore, histopathology results of the internal organs revealed no detectable inflammation. These results demonstrated that the rhizome extract of T. violacea was potentially safe for consumption orally even in chronic concentration. In vitro antioxidant evaluation showed that the essential oil, fresh and dried methanolic extracts exhibited potent antioxidant activities in a concentration dependent manner. Phytochemical investigation reveals that the fresh and the dry extract of RTV are rich in flavonoid, flavonol, phenols, tannin and proanthocyanidin, while the essential oil contained dimethy disulfide, dimethyl trisulfide, (methyl methylthio) methyl, 2,4-dithiapentane (11.35 percent) and (methylthio) acetic acid, 2- (methylthio) ethanol, 3-(methylthio) - and propanenitrile (7.20 percent). The fresh extract had higher radicals scavenging activity than the essential oil or dried extract, with 50 percentage inhibition of DPPH, hydrogen peroxide and lipid peroxidation at a concentration of 35.0 ± 0.12, 19.3 ± 0.11 and 17.9 ± 0.15 μg/ml respectively. Oral administration of methanolic extract of RTV in 125, 250 and 500 mg/kg to female Wistar rats significantly inhibited reduction of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). The extracts also inhibited (p< 0.05) lipid peroxidation in normal, high cholesterol and diet induced atherosclerosis fed rats in a dose dependant manner. Also the extract (250 and 500 mg/kg/bwt/day) caused a significant (p<0.05) improvement in body weight of treated animals compared with untreated hypercholesterolemia control rats. The extracts also protected significantly (p<0.05) against atherogenic diet induced liver damage or fatty streaks formation in the aorta as revealed by histological examination. The anti-cholesterolemia and anti-atherosclerotic activities of the extract compared favorably well with standard drugs Gemfibrozil and Atorvastatin respectively. Conclusively, rhizomes of T. violacea possess significant anti-atherogenic activity and its mechanism of action(s) may be due to its antioxidant and anti-hypercholesterolemia properties. The results of this study also suggested that rhizome of T. violacea is relatively safe for human consumption and it may be used as an alternative to garlic.

- Description: A study to assess the potentials of some commensal bacteria that belong to Staphylococcus, Acinetobacter and Stenotrophomonas genera as reservoirs of antibiotic resistance determinants in the environment of Nkonkobe Municipality of the Eastern Cape Province, South Africa, was carried out using standard microbiological and molecular techniques. A total of 120 Staphylococcus isolates which consisted of Staphylococcus haemolyticus (30%), Staphylococcus aureus (23.3%) from pig; Staphylococcus capitis (15%) from goat; Staphylococcus heamolyticus (5%) and Staphylococcus xylosus (15%) from cattle and other Staphylococci (11%) from dead chicken and pigs were isolated. About 23.3% of these isolates were coagulase positive and 76.7% were coagulase negative. This difference in prevalence along coagulase production divide was statistically significant (p < 0.05). Eighty-six Acinetobacter species (Acinetobacter baumannii/calcoaceticus and Acinetobacter haemolyticus) were also isolated from Alice and Fort Beaufort towns samples, while 125 Stenotrophomonas maltophilia isolates were from grass root rhizosphere (96%) and soil butternut root rhizosphere (4%). Between 75-100% of the Staphylococccus species were resistant to Penicillin G, tetracycline, sulphamethaxole and nalidixic acid; about 38 % were methicillin resistant, consisting of 12.6% methicillin resistant Staphylococcus aureus (MRSA) from pig and a total of 12% vancomycin resistant were observed. Also, 12% of the isolates were erythromycin resistant while 40.2 % were resistant to the third generation cephalosporin, ceftazidime. The antibiotic resistance genes vanA, VanB, eryA, eryB, eryC were not detected in all the phenotypically resistant Staphylococccus species, but mec A gene and mph genes were detected. In the Acinetobacter species, a wide range of 30-100% resistance to penicillin G, ceftriazone, nitrofurantoin, erythromycin, and augmentin was observed. Polymerase chain reaction (PCR) revealed the presence of Tet(B) and Tet(39) genes in these species, while Tet (A), Tet(M) and Tet(H) were absent. Also, 9.3% of the Acinetobacter species showed phenotypic production of extended spectrum beta lactamases (ESBLs) while 3.5% were positive for the presence of blaCTX-M-1 genes. The Stenotrophomonas maltophilia isolates showed varying resistance to meropenem (8.9%), cefuroxime (95.6 %), ampicillin-sulbactam (53.9%), ceftazidime (10.7%), cefepime (29.3 %), minocycline (2.2%), kanamycin (56.9%), ofloxacin (2.9%), levofloxacin (1.3%), moxifloxacin (2.8%), ciprofloxacin (24.3%), gatifloxacin (1.3%), polymyxin B (2.9 %), cotrimoxazole (26.1%), trimethoprim (98.6%), aztreonam(58%) and Polymyxin B (2.9 %). The isolates exhibited significant susceptibility to the fluoroquinolones (74.3-94.7 %), polymycin (97.1%) and meropenem (88.1%). Only sul3 genes were the only sulphonamide resistance gene detected among the trimethoprim-sulphamethoxazole resistant isolates. The observed multiple antibiotic resistance indeces (MARI) of >2 for Staphylococcus species, Acinetobacter species and Stenotrophomonas maltophilia suggest that they have arisen from high-risk sources where antibiotics are in constant arbitrary use resulting in high selective pressure. The presence of tetracycline resistance genes in Acinetobacter species justifies the observed phenotypic resistance to oxytetracycline and intermediate resistance to minocycline. High phenotypic resistance and the presence of some resistance genes in Staphylococcus species is a possible threat to public health and suggests animals to be important reservoirs of antibiotic resistance determinants in the environment. Indiscriminate use of antibiotics induces this kind of antibiotic resistance and should be discouraged. Personal hygiene is encouraged as it reduces the load of Acinetobacter species contacted from the environment that may be difficult to control. Commensal Stenotrophomonas maltophilia are as important as their clinical counterparts due to their roles in opportunistic infection, antibiotic resistance and their associated genes, especially sul gene. Personal hygiene is hereby advocated especially when in contact with soil, plants and plants’ rhizospheric soil.

- Description: The study emanates from the constitutional imperatives with regard to the role of local government in community development. The notion of cooperative governance is envisaged in the South African Constitution which stipulates that all spheres of government must adhere to the principles of cooperative government and must conduct their activities within the parameters prescribed by the Constitution. The purpose is to support and strengthen the capacity of the local governments to manage their own affairs and to perform their functions. The basic values and principles governing public administration entail that: it must be broadly representative of the people of South Africa in order to redress the imbalances. The existing gaps in the legislation on decision making power at the local level of the municipality, be it in a ward committee or sub council, have not been adequately addressed in the post 1994 democratic dispensation. It is in this context that this study seeks to address these gaps and obstacles, and contribute to the design and development of a decentralized cooperative governance model, specifically to the six metropolitan municipalities and also provide a basis for further research. The findings of the research could be adapted as a national policy in the empowering of municipalities through the dispersal of democratic power which is an essential ingredient of inclusive governance. Based on a case study of six metropolitan municipalities, the research is intended to contribute to the development of empirically grounded; praxis and practical guideline in decentralized cooperative governance which can be adopted and institutionalized in public administration. It is believed that a study of decentralized cooperative governance adds value in that it seeks to link decentralized power and local development. Rather than civil society organisations being seen as adversarial, a creative partnership with the state in local development is crucial. This political assimilation is critical in the construction of democracy through fusing the substantive values of a political culture with the procedural requisites of democratic accountability. This serves to fragment and disperse political power and maintain a system of checks and balances with regard to the exercise of governmental power. The capacity for innovation, flexibility and change can be enhanced at the local level, and it is a cliché that local decision making is viewed as more democratic in contrast to central, top-down decision-making processes. A syncretistic model for local government based on the political adaptation of political and inclusive decentralisation is outlined.

- Description: More and more people worldwide are becoming “carbon conscious”. This means they are becoming increasingly aware of the imminent adverse effects of global warming. Of late there has been an urgent drive for governments to be on the forefront of all carbon mitigation initiatives. One such drive involves the United Nations Framework Convention on Climate Change whose parties have been meeting regularly under the banner of Conference of Parties (COP) since 1995. At this conference, parties to the convention review progress made in dealing with climate change. Also key to the deliberations in such meetings are better ways of developing cleaner “carbon free” energy sources. Energy sources of this nature are commonly known as renewable energy sources. In essence global energy trends are constantly moving towards development of more renewable energy sources. It is an undeniable fact that some of viable renewable energy sources especially those with bulk capacity are usually located remotely from load centers. This inevitable reality necessitates the construction of long distance bulk power transmission corridors to link generation sites with load centers. Due to its many inherent advantages over High Voltage Alternate Current (HVAC) for long distance power transmission, High Voltage Direct Current (HVDC) is gradually winning the favor of many utilities. In fact, recent advances in HVDC technology have encouraged many utilities to explore the possibility of harnessing remotely located renewable energy sources which would have otherwise not been viable with HVAC transmission. Through the unfortunate and inevitable phenomenon known as corona effect, overhead HVDC conductors suffer real power losses to the air dielectric surrounding them. Through corona, part of the energy carried on the transmission line is expended through ionization and movement of charges in the air dielectric. This study combined physics, mathematical as well engineering concepts to review corona phenomenon around HVDC lines with specific emphasis on space charge generation and motion within ionized DC fields as well as the influence of temperature on corona discharge or power loss. Also, unlike HVAC, performance of an HVDC system relies heavily on the availability of a reliable and robust telecommunication system. One of the key ways of ensuring reliability of a telecommunication system is by making sure that reliable power supplies are in place to power remote repeater stations. A novel concept of quasi-autonomous corona-based power supply (or QC power supply in short) that works on the principle of magnetohydrodymic (MHD) power generation was developed. A small scale experiment was then designed to assess the feasibility of such power supplies. The experiment was conducted with DC supply of a maximum rated voltage of 30 kVDC and generated up to 6 VDC at an optimum ambient temperature of 23°C. These results have confirmed that with further development QC power supplies have the potential of proving reliable power to remotely located repeaters or any other small critical loads along the stretch of the HVDC transmission line. Practical HVDC transmission systems operate voltages in the excess of 500 kV. By linear extrapolation of the above mentioned results; one would expect to yield up to 100-, 120- and 160-VDC from a 500-, 600- and 800- kV HVDC system, respectively. Although the study succeeded in conceptualizing a CMHD idea upon which the novel QC power supply was developed, quite extensive and rigorous design, modeling, prototyping and experimentation processes are still required before the first QC power supply can be commissioned on a practical HVDC line

- Description: The primary aim of this thesis is to provide a text-based literary study exploring the characters and themes created by K. Sello Duiker in the three novels, Thirteen Cents, The Quiet Violence of Dreams and The Hidden Star. Duiker’s work is significant because it highlights prominent societal challenges prevalent in post-apartheid society. By analysing Duiker’s novels one acquires a better understanding of this author, an understanding of the world that contributed to the creation of his texts and his contribution to South African literature. Insight into Duiker’s fictional world allows for a careful investigation of the prominent societal issues prevalent in Duiker’s work - a world riddled with violence, issues of sexuality and psychological distress. For this purpose this thesis is premised on the notion that underpinning K. Sello Duiker’s oeuvre is a central focus on dreams, sexuality and fantasy. Logically, therefore, the main focus of the study is specifically on the inner working of the characters’ minds and how they deal/ or are unable to cope with contemporary social concerns, often resulting in psychological turmoil and dysfunctionality. For this reason, prominent themes examined in this study are the interpretation of dreams, an exploration of sexuality and an examination of fantasy in the three novels. Psychoanalytic literary theory, with the main focus being specifically on the theories presented by Sigmund Freud is used as an analytic tool to read Duiker’s texts. Psychoanalytic theory is arguably the most appropriate for analysing Duiker’s novels as it allows one to investigate the characters’ psyches and the psychological effect of societal influences on these characters. In addition, one is also able to examine how the characters are able/ unable to deal with the trauma caused by the contemporary issues in society – issues of violence, sexuality and psychological distress. Thus, one is able to grasp an overall understanding of the characters’ behaviour and actions. Furthermore, the characters’ experiences are based on the behaviour and incidents of real people, people suffering from psychological dysfunctionality, sexuality issues and identity crisis. The first chapter discusses post-apartheid literature, and provides a brief background on Duiker, his works and his conception as a writer. Chapter two provides an overview of psychoanalytic theory and on the relevant theories of Sigmund Freud. Chapter three offers a reading of Thirteen Cents, a novel that pays particular attention to the lives of children living on the streets of Cape Town. In the next chapter The Quiet Violence of Dreams is examined with a special focus on Duiker’s experimentation with form in the construction of this novel. Aspects pertaining to sexuality and dreams are also examined. Chapter five pays particular attention to magical realism and fantasy in The Hidden Star.

Enlarging the place of human rights and development in international trade regulation: an evaluation of the problems and prospects of incorporating a social clause in the legal framework of the World Trade Organization

- Description: An agreement on the inclusion of a social clause in the World Trade Organization‟s (WTO) multilateral trade agreements largely depends on reassuring objecting member states that such inclusion will contribute to an improved recognition of core labour standards in trade, without altering the competitive advantage of one trading partner over another. Reassurance must be given to the effect that incorporating a social clause in the WTO legal framework would not be used as a trade restricting mechanism which might have direct, negative effects on the development of countries worldwide. Such an argument may not be won easily from a legal and economic perspective. There is an omnipresent conflict at the international level between the basic values underlying multilateral trade agreements and principles governing the protection of core labour standards. On the one hand, supporting the stance of free trade is the fundamental force of profit maximization while on the other hand, and in direct opposition to this market driven value system, are human rights-based calls for recognising core labour standards in employment matters related to trade. Increased international trade is a powerful tool for tackling poverty and social misery worldwide. It could thus be important to adopt a legal framework in the multilateral trade system to harness potential opportunities a trade-labour linkage could provide. In that case, the legal questions of whether or not there should be a tradeoff between the right to trade and compliance with core labour standards and whether a social clause in the WTO would achieve this purpose had to be addressed. However, without a compatible underpinning legal framework of universally accepted trade-labour standards, incorporating a social clause in the WTO would be a misplaced legal objective which is unachievable as it could lead to a conflict between the WTO and the International Labour Organisation (ILO) and at most could create a legal fiction whose results may not be positively measurable. Setting two international legal norms at conflict with each other is systematically studied as a conflict in which the values of the global market economy are in a supposed confrontation with those protecting core labour standards as human rights. Therefore, this study undertook a contemporary legal analysis of the possibilities and challenges of incorporating a social clause in the WTO for purposes of entrenching the protection of core labour standards. It put forward arguments and tentative proposals for a trade-labour linkage legal framework which could dispel calls for excluding a social clause in the WTO.

- Description: International Aid or Official Development Assistance (ODA), especially its implementation and effectiveness, has long been and continues to be a vigorously contested matter amongst the stakeholders in the development arena. The objective of this study is to evaluate the effectiveness of ODA in two municipalities in the Eastern Cape – Buffalo City and Nelson Mandela Metropolitan Municipalities – during the period 2005–2010. This period coincided with the introduction of the Paris Declaration (PD), an intervention intended to improve the ODA or Aid landscape globally. This was also the period during which the so-called service delivery protests in almost all municipalities in South Africa escalated. A diversified methodology including both quantitative and qualitative approaches was used in this study while adhering to the evaluation framework of the Paris Declaration as recommended by the Organisation for Economic Cooperation and Development (OECD). This framework put special focus on the five principles of ownership, alignment, harmonisation, managing for results and mutual accountability. Of particular significance in this study is the special attention paid to the actual beneficiaries on the ground, namely the communities, which is contrary to most existing Paris Declaration evaluations. The research findings suggested that there had been no conscious efforts to implement the Paris Declaration in the two municipalities that were investigated. Furthermore, the prevailing weaknesses in governance, coupled with both administrative and operational paralysis in these two institutions, provided for less than fertile ground for this intervention to thrive.The findings also highlighted that ODA programmes were very poorly known by most stakeholders, especially the communities who were supposed to benefit directly from this assistance. These results also underscored the partisan nature of ODA and how it influenced the perceptions of the various key players. The success and future of ODA programmes in South Africa, particularly in municipalities, will largely rely on “Active Citizenry”. Although ODA’s contribution to South Africa seems negligible in monetary terms, its significance lies among others in the innovations, piloting, risk mitigation, catalytic initiatives and capacity development it introduces or generates and which need to be correctly exploited, implemented and maximised. ODA in South Africa should therefore focus at the local level, the municipalities, which represent the interface between the citizens and the state. To ensure that the ensuing innovations are optimally cascaded down in an organised and effective manner to where they are mostly needed, ODA should preferably operate at the strategic level in municipalities. This would in turn assist in counteracting the current high levels of poverty and inequality in the country. Study findings further suggest that South Africa should cease its current ambivalence regarding ODA and refrain from the so-called “Triangular” ODA in support of the rest of Africa. The demands in it’s own back yard are steadily mounting. This is clearly reflected by the continuous service delivery protests and instability in several municipalities in South Africa.

- Description: Human Immuno-Deficiency Virus and Acquired Immune-Deficiency Syndrome communication remains one of the most significant tools in the fight against HIV/AIDS given the absence of the cure to fight the growth and spread of the global pandemic. Through the use of information, HIV/AIDS communication seeks to empower recipients or societies with skills that will help reduce their risk of infection. South Africa has seen a high visibility of HIV/AIDS communication programmes or campaigns aimed at empowering different audiences, whilst paying particular emphasis on the most vulnerable. Young people, in particular young women, have a higher prevalence of HIV/AIDS in South Africa. This has prompted the development of many youth focused communication campaigns which have sought to address factors that increase young people`s vulnerability to HIV infection. However, despite the high visibility of HIV/AIDS communication campaigns targeting young people, high risk behaviours are still being seen among young women. Important to note are the high teenage pregnancy rates, growing abuse of substances and even the premature engagement of sexual activities among female youths. This, therefore, raises questions on the effect of HIV/AIDS communication programmes in encouraging protective behaviour against risky behavioural practices amongst young women. Using both quantitative and qualitative research approaches to this study, an investigation was conducted into whether current HIV/AIDS communication campaigns have been limited (in terms of effectiveness) when it comes to communicating with young women on issues relating to HIV/AIDS. Awareness of HIV/AIDS and HIV/AIDS communication programmes, relevance of HIV/AIDS communication programmes, the factors that influence the use and understanding of HIV/AIDS messages and the impact of HIV/AIDS communication on attitude and behaviour change amongst female youths is measured. A total of 350 questionnaire copies were self-administered to 350 participants, with a 100 percent response rate. From the 350 participants, seventy five took part in focus group discussions. Data obtained was analysed using SPSS (for descriptive statistics), and the grounded theory. The results of the study indicate that all participants were aware of HIV/AIDS with at least 60% of the participants aware of at least three HIV/AIDS communication campaigns. When measuring the relevance of HIV/AIDS communication campaigns, participants (58%) indicate that issues discussed in most HIV/AIDS communication campaigns increased the relevance of HIV/AIDS messages to young women although such relevance was, for some respondents, affected by limited access to communication campaigns. Results also show that levels of knowledge and understanding of factors that expose young women to HIV infections differed amongst participants in as much as the factors that hinder the use of advice contained in HIV/AIDS messages also differed. Sixty-nine percent of the participants have knowledge and a better understanding of factors that expose young females to HIV infections. Twenty-five percent of the participants identified peer pressure, whilst 23% identified limited access to HIV/AIDS communication campaigns and another 18% identified a disregard of HIV/AIDS messages as significant factors that limit the ability of individuals to implement advice contained in HIV/AIDS messages. The results also indicate that although HIV/AIDS communication campaigns seem to have played a role in empowering some participants, there is still a significant minority whom communication has not effectively communicated with. Based on these findings, the study suggests, amongst other things, the need to intensify current HIV/AIDS communication campaigns through the provision of consistent messages on appropriate condom use, the identification of easily accessible communication channels and the development of thought provoking and attention grabbing campaigns as well as the need to continue to directly involve young women in the processes of their own development.

- Description: Knowledge is now regarded as the most important resource surpassing other resources like land and capital. It is a foregone conclusion that knowledge flows out of organizations through various ways such as resignations, retirement and death yet, it does not seem as if organizations are employing strategies to retain such a vital component of production and service delivery. This study investigated the knowledge retention strategies in three Southern Africa Development Community (SADC) public broadcasting organizations of the South African Broadcasting Corporation in South African (SABC), the Department of Broadcasting Services (DBS) in Botswana and the Zimbabwe Broadcasting Corporation (ZBC) in Zimbabwe. The aim of this study was to establish how knowledge is captured and retained at such organizations. The objectives of the study were; to find out the types of strategies the three broadcasting organizations employ to capture and retain knowledge; establish how the three broadcasting organizational cultures enable knowledge acquisition, transfer, sharing and retention; establish the role of ICTs as tools and enablers of knowledge retention, creation, transfer and sharing in the three broadcasting organizations; and to propose recommendations on the best strategies for retention of knowledge in the three public broadcasting organizations as well as suggest areas for further and future research. v The study used the survey method and employed the triangulation design for data gathering. Data were collected from three SADC public broadcasting organizations. The population sample comprised 240 professional staff including 38 managers from different sections of the broadcasting organizations. The researcher collected data by administering a questionnaire to staff, interviews with managers and observations. Documentary analysis was also conducted in order to supplement data and fill in gaps. The researcher was mainly interested in gathering data that would give a comprehensive picture about knowledge retention methods in broadcasting organizations. There were four main findings. First, knowledge management as a relatively new concept and practice has not yet been properly embraced in the public broadcasting organization system in order to capture and retain knowledge that is acquired and generated in the organizations. There are no measures put in place in the organizations to retain the knowledge to ensure that once those who hold vital tacit knowledge are gone, the knowledge may still be available and accessible. Second, the study established that the respective organizational cultures impede on organizational knowledge retention. The study established that there was no culture of knowledge sharing. It also emerged that employees were not free to share their knowledge because of government regulations, prevailing political contexts, mistrust and general lack of incentive to share knowledge. Third, the study established that the organizations have no strategies or systems in place to capture the experts‟ knowledge or the knowledge of experienced staff and vi those approaching retiring age. The Human Resources Departments hold exit interviews that cover issues purely to do with why the person is leaving the organization instead of recording the work experiences and expertise of the departing employees. Fourth, the study revealed that the public broadcasting organizations still lag behind in collaborative and communicative technologies that facilitate knowledge transfer and sharing of tacit knowledge but retention of knowledge generally. The study also found that, some of the organizations studied did not have internet connectivity and websites were not yet functional, which hampered acquisition and sharing of knowledge for retention purposes. The importance of this study is that it has made a contribution and provided literature on knowledge retention strategies for public broadcasting corporations as part of knowledge management practice. On the basis of these findings the study recommended the following: appointment of knowledge management officers, establishment of Communities of Practice, encouraging knowledge sharing between employees, introduction of joint programmes with other broadcasting organizations by managers and their supervision of mentoring programmes; organizations to facilitate acquisition of information and communication technologies that enable knowledge management

- Description: Resource control as a form of community participation in the mineral economy has gained much recognition. One prevailing argument is that direct control of natural resources by local communities is an important precondition for equitable utilisation of the natural resource wealth, peaceful co-existence between mining corporations and indigenous communities, and congenial relations between local communities and the state. Studies have also shown that the absence of direct community control of mineral wealth remains a major factor in the communal resistance and socio-political conflict witnessed in the natural resource-endowed regions of countries such as Nigeria, Ecuador, Sierra Leone and the Democratic Republic of the Congo. However, little is known about mineral resource control at the community level. Does community control necessarily translate to equity? How does local involvement in the mobilisation of mining royalties benefit different segments of the community? Indeed, how do different segments of the community “control” the wealth? What is the specific model adopted to engender broad-based community participation in the utilisation of mineral wealth – and does it matter? These theoretical and practical questions were the impetus for undertaking this study in the Royal Bafokeng and Bakgatla Ba Kgafela – two platinum-rich ‘traditional’ communities in South Africa’s North West Province that have significant control over platinum resources in their territories. Utilising ethnographic data collected in the two study communities in 2008 and 2009, the thesis examines the character of community participation in platinum wealth utilisation; specifically, the conditions under which community participation promotes or hinders sustainable community development. The analysis uses a “three-dimensional participation ladder” conceptual scheme, based in part on Sherry Arnstein’s (1969) “ladder of citizen participation” and subsequent typologies of participation. Among the key findings of the thesis are that despite observed benefits, the interface of resource wealth and community development is fraught with tokenistic participation, elite-targeted grassroots anger, and local tensions – all linked to the contradictory nature of participation. The thesis further reveals that in some instances the challenge of platinum wealth-engendered community development tends to undermine existing customary and democratic spaces for participation, and that this is exacerbated by community-level issues such as poverty and inequality. The findings of the study compel a shift of analytical focus from conflict as an epiphenomenon of collective community exclusion and deprivation (as in the case of many natural-rich countries in Sub-Saharan Africa and elsewhere), to conflict as also resulting from collective community inclusion (in natural resource utilisation). At the policy level, the study generates insights that will, hopefully, assist mineral resource-endowed countries, such as South Africa, in dealing with the challenge of developing appropriate policy frameworks for regulating business and social partnerships between local communities and mining corporations, and within resource-rich communities themselves.

- Description: The thesis examines the photographic collection of Joseph Denfield, an archivist and historian who experimented with photography over a twenty-year period. The study is located within the field of critical visual studies that focuses on historical photography in its depiction of identities and groups in the context of social change. The thesis pays attention to the manner and extent to which Denfield participated in regional visual economies at various moments during his photographic career in order to establish his contribution towards a visual history in Africa and more broadly Southern Africa. It follows Denfield’s career trajectory chronologically. It begins with a study of his photographic work in Nigeria which was oriented around so-called ‘pagan tribes’ and which was framed within the discourse of ethnography. It then pays attention to his growth as an artist in photography that resulted from years of exhibiting in salons. I read these photographs and texts in relation to his earlier work in Nigeria given the extent to which he drew on anthropological discourses. It is through his involvement with photographic art circles that Denfield developed as a historian as a result of his research into the history of photography and regional visual histories. This took the form of both unearthing historical photographs as well as photographing historical sites to construct the past in particular ways through the visual. At each stage he translated these histories into public forms of representation and power thus he figures among a small group of ‘colonial’ photographers that shaped the visual economy of Southern Africa. Through a detailed study of his work, the thesis thus aims to re-think through new dimensions of visual culture.

- Description: Despite phenomenal success of the commercial agricultural sector in South Africa and significant progress in integrating smallholders since democratic reforms, food security concerns remain. Recent global increases in food prices have further exacerbated vulnerabilities and made it imperative to examine alternative food production questions in the country. Organic agriculture is identified as one of the sustainable approaches to farming and offers insights towards a paradigm shift in food and nutritional security. Notwithstanding, consumer awareness, knowledge and consumption of organic foods are significantly lower in developing than developed countries. Risks associated with adoption of organic practices need to be explored to address the supply and demand constraints. Similarly, while consumer awareness of organic foods is the first step in developing demand for organic products, it does not necessarily translate to consumption. Therefore it is important to investigate these issues. The objectives of this study were to: (i) describe the demographic and socio-economic characteristics of organic farmers and consumers; (ii) establish the determinants of farmers‘ decision to participate in organic farming distinguishing between the fully-certified organic, partially-certified organic and non-organic farmers; (iii) elicit farmers risk preferences and empirically analyse farmers sources of risk and risk management strategies; (iv) explore consumer awareness, perceptions and attitudes regarding organic products; and (v) identify the factors that influence consumer‘s preference and consumption of organic products. A total of 400 respondents were surveyed, consisting of 200 smallholder farmers in KwaZulu-Natal and 200 consumers in the Eastern Cape. The KwaZulu-Natal study was conducted earlier and identified the following as major sources of risk, lack of consumer awareness of organic products and lack of information among producers about consumer preferences for organic products. This informed the need to undertake a consumer awareness and preference study, in order to inform producers. The Eastern Cape is a bordering province to KwaZulu-Natal with similar socio economic conditions and a major consumer of produce from KwaZulu-Natal. It was also expected that in the intervening period there could have been awareness about the product. An vii indication of its appeal would not be in the consumption of the product by the people who grow it, but by consumers who reside in bordering regions. Producer and household questionnaires were used to record household activities, socio-economic and institutional data as well as household demographics through personal interviews. The Arrow Pratt Absolute Risk Aversion (APARA) coefficient was used to measure the farmer‘s degree of risk aversion and the experimental gambling approach to establish the risk classification. Consumers were also asked about their awareness and knowledge about organics, attitudes and perceptions towards organics, preference and consumption patterns. The ordered probit results indicate that older farmers, who are less risk averse and reside in the sub-ward Ogagwini, Ezigani, and Hwayi were more likely to be certified organic farmers. Similarly, the propensity to adopt organic farming is positively correlated to household size, livestock ownership, asset base and tenure security. The risk analysis indicates that at higher pay-offs most farmers are intermediate to moderately risk-averse, with little variation according to personal characteristics, and that non-organic farmers tend to be more risk averse than fully-certified and partially-certified farmers. In general, price, production and financial risks were perceived as the most important sources of risk. Using Principal Component Analysis (PCA), seven principal components (PCs) explaining 66.13% of the variation were extracted. Socio economic factors having a significant effect on the various sources of risk are age, gender, education, location, information access and risk taking ability. The most important traditional risk management strategies used by the surveyed farmers are crop diversification, precautionary savings and participating in social networks. There was general awareness of what constituted organic foods with many consumers associating organic foods with health and nutrition, chemical free and produced using indigenous methods of production. However, there was low awareness of organic products among consumers with little or no knowledge of organic certification and standards. According to the logit model the major factors influencing consumer awareness of organic products are: gender, education, employment status, and location of the respondents, person/household member responsible for shopping and the price perception of the decision maker. The discriminant analysis showed that the consumption of organic products is significantly affected by age of the consumer, viii location, person/household member responsible for shopping, consumer awareness of organics, price perception and label trust. The findings from this study provides useful practical insights for policy makers, farm advisers and researchers in the design of effective and efficient policies, programmes and projects which can affect the adoption of organic practices, increase smallholder farmers capacity to manage risk and drive growth in the organic food market.
