- Description: This study focused on community participation in relation to policy formulation in Lesotho. It paid particular attention to whether the Lesotho community participated in the formulation of the Lesotho Land Bill 2009. Literature related to the concept of participatory development, community participation and policy formulation was reviewed. From the literature, it was clear that the attainment of effective community participation in policy formulation is not something that can take place overnight and this makes community participation a crucial aspect of any development project. The study used the qualitative approach to provide more information and detailed examination of community participation in the formulation of the Lesotho Land Bill 2009. This approach adopted the case study design. The data was collected using focus groups, interview schedule and document analysis. The study found that the government did not consult widely on the Bill before it was enacted into an Act of parliament. Therefore, it recommends that the government of Lesotho should involve all relevant stakeholders to participate in policy formulation. This will help to establish a link between the government and civil society stakeholders at local levels, for participatory policy-making to be effective.

- Description: The objective of the study was to determine the antioxidant activity (AA) and the quality of meat from goats and chickens supplemented with Moringa (Moringa oleifera) leaves. For the first experimental chapter, eighteen 9 months old Xhosa lop-eared, castrated goats with an average body weight of 14 kg were used. There were three supplements namely, Moringa oleifera leaves, sunflower cake and grass hay. There were six goats per supplement. The goats were slaughtered after 60 days of supplementation and the Muscularis longissimus thoracis et lumborum (LTL) of the right side of each goat was used to determine fatty acid composition, total phenolic content (TPC), diphenylpicrylhydrazyl (DPPH) assay, 2, 2 azino-bis (3- ethylbenzothiazoline-6-sulphonic diammonium salt (ABTS) assay and reducing power assay of meat. Glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) and lipid peroxidation (thiobarbituric acid reactive substances, TBARS) were taken as parameters to evaluate in vivo AA of the meat. For the second experiment, twelve male broilers were used in four groups of dietary supplementation. Three broilers were allocated per group. After slaughter, the breast muscle was sampled for total phenols, flavonoids, proanthocyanidins, TPC, ABTS, GSH, CAT, SOD, lipid peroxidation, ultimate pH (pH24), colour (L* (lightness), a* (redness), b* (yellowness)), WB-shear force and cooking loss. In both chapters Moringa leaves exhibited the highest AA. Meat from goats supplement with Moringa exhibited the highest AA. Meat from broilers supplemented with a mixture of Moringa leaves, broiler finisher and crushed maize, had the highest (P < 0.05) pH24 and L* values. Moringa can therefore be used to preserve meat without changing the quality of meat.

- Description: Characterization of village chicken phealth and management practices in the Amatola Basin of the Eastern Cape Province, South Africa By Njongenhle M. B. NYONI The majority of rural households in South Africa own village chickens which contribute significantly to their livelihoods. However, limited research has been conducted to characterize, understand and develop village chicken production in South Africa. This hinders the designing and implementation of village chicken-based developmental programmes that will benefit farmers in rural areas. Thus, it is imperative to initiate studies to describe village chicken production. This study was conducted to characterize village chicken production in Amatola Basin of the Eastern Cape Province of South Africa. Baseline information was gathered using a questionnaire survey of 81 identified from 7 out of 13 villages using snowball sampling technique. Consequently, 20 households were selected to participate in a monitoring study (from July 2010 to June 2011) through purposive sampling. Most (60%) chicken flocks were owned by women and mainly raised to meet household food requirements. Some (28.4%) farmers occasionally sold cocks and hens to neighbours, at an average price of R50 (USD7.55) per bird, as a way of culling their flocks and generating income. However, village chickens were mainly kept for food security rather than for their terminal benefit of cash. Although, all chicken flocks were produced under the scavenging feeding system, most (96%) flocks were provided with supplementary feed and drinking water. A majority (93.8%) of households also provided some form of shelter for their chickens. The mean cock to hen to chick ratio was 1:5:15. On average, iii each household owned 17 (±2 S.E.M.) chickens, and hens had 3.3 clutches per annum. Chicks hatched and chickens received as gifts represented the flock entries, while exits included mortality, consumption, sales and gifts or donations, in that order. Generally, both exits and entries were more pronounced in the summer season than in other seasons. Most (81.5%) farmers experienced chicken losses due to predation and health related problems. Parasitism ranked high amongst the village chicken health challenges. During monitoring, the endoprasites identified included nematodes, cestodes and protozoa. Coccidia were the most prevalent endoparasites. The chickens were also infested with a variety of ectoparasites namely: mites, lice, fleas and ticks. The sticktight flea Echidnophaga gallinacean was the most prevalent species. Although ectoparasite infestations were most pronounced in summer, almost all chickens harbored one or more of these parasites throughout the study period. The prevalence and intensity of parasite infestations were significantly (P<0.05) higher in the summer season compared to the other seasons. This was followed by the autumn, spring and winter seasons, respectively. The majority (77.5%) of farmers resorted to alternative remedies, mostly medicinal plants, for treating diseases and controlling parasites. Medicinal plants were used because they were locally available, cheap and perceived to be effective. Therefore, village chicken production in the rural Eastern Cape Province is characterised by several challenges which counter the significant role chickens play in the livelihood of rural households.

- Description: Different forms of racial segregation have been practiced in different countries the world over. However, the nature of South Africa‟s apartheid system, as it was practiced from 1948 until the dawn of the democratic dispensation in 1994, has been a subject of debate in South Africa and even beyond. Apartheid was a policy that was designed by the then ruling Nationalist Party for purposes of dividing and stratifying South Africa along racial lines - whites, blacks, coloureds and Asians. It thus promoted racial segregation and/or unequal stratification of society. In South Africa‟s hierarchy of apartheid, blacks, who constituted the majority of the population, were ironically the most destitute and segregated. Some historians believe that South Africa‟s racial policy was designed against the backdrop of Jim Crow, a similar system of racial discrimination which was instituted in the American South late in the 1890s through the 20th century. Jim Crow and apartheid are, in this study, considered as sides of the same coin; hence for the sake of convenience, the word apartheid is used to subsume Jim Crow. Although South Africa‟s apartheid system was influenced by different ideologies, for example German missiology as applied by the Dutch Reformed Church, historian Hermann Giliomee (2003: 373) insists that „the segregationist practice of the American South was particularly influential.‟ Given the ideological relationship between apartheid and Jim Crow, the present study investigates the interplay of compatibility between apartheid/Jim Crow and crime and violence as reflected in selected works of Richard Wright (African American novelist) and Athol Fugard (South African playwright). The aim of the study is firstly, to examine the works in order to analyse them as responses to apartheid and by extension colonial domination and secondly to investigate crime and violence. The three criminological theories selected for this study are strain theory (by Robert Merton), subculture theory (Edwin Sutherland) and labelling theory (Howard Becker). While criminological theory provides an empirical dimension to the study, postcolonial theory situates the study within a specified space, which is the postcolonial context. The postcolonial is, however understood, not as a demarcated historical space, but as a continuum, from the dawn of colonization to the unforeseeable future. Three postcolonial theorists have been identified for the purposes of this study. These are: Frantz Fanon, Homi Bhabha and Bill Ashcroft. Fanon‟s psychoanalysis of the colonized, Homi Bhabha‟s Third Space and hybridity as well as Ashcroft‟s postcolonial transformation are key concepts in understanding the different ways in which the colonized deal with the consequences of colonization. It has been suggested particularly in Edward Said‟s Orientalism (1978) that the discourse of orientalism creates the Oriental, as if Orientals were a passive object of the colonial adventure. This study uses Bhabha‟s and Ashcroft‟s theory of colonial discourse to argue that the colonized are not only objects of the colonial enterprise but also active participants in the process of opening survival spaces for self-realization. The various criminal activities that the colonized engage in (as represented in the selected works of Richard Wright and Athol Fugard) are in this study viewed as ways of inscribing their subjectivity within an exclusive colonial system.

- Description: This study used integration as the overarching conceptual framework to investigate socio-spatial integration in post-apartheid South Africa. The study adopted the embedded case study design to investigate the spatial and social aspects of integration in former white residential suburbs in East London, South Africa. Recognising that integration occurred in different registers, this study used data from the South African Property Transfer Guide (SAPTG) database to investigate spatial-temporal integration in East London‟s residential suburbs from 1993 to 2008. A total of 21,683 residential property transfers were reviewed in 46 suburbs, and transfers to Blacks were identified. The residential property transfers were mapped to identify the nature of spatial integration. To investigate social integration, in-depth personal interviews were conducted on a purposively drawn sample of residents in the three case study suburbs of Southernwood, Cambridge and Gonubie. The interviews focused on three proxy indicators of social capital at neighbourhood level. The results of the study showed that post-apartheid spatial integration in East London closely followed the class-based residential template. Contrary to predictions prior to, and following apartheid‟s demise, the study showed that spatial integration occurred without racial conflicts. The study also found that social integration in the residential suburbs reflected the neighbourhood context and personal preferences, and was highly fluid. Although feelings of racial distance were evident, there were also indications of social cohesion, which were dynamic and uneven in time and space. Based on the data and the dialectical nature of spatial and social integration, the study concluded that fragmentation and integration are likely to continue coexisting in the South African city.

- Description: The overall objective of the whole study was to assess whether conservation agriculture (CA) systems can work in the Eastern Cape Province (EC). The CA systems were engaged through cover cropping to address land degradation problems by emphasizing high biomass production in order to realize short term benefits such as moisture conservation, weed suppression and soil fertility benefits under rainfed conditions in the central region of the Eastern Cape province. Since rainfall is the most limiting factor to crop production in the EC, a within season rainfall distribution analysis was conducted to expose the quality of the season (onset, end and duration) and hence the feasibility of CA systems to guide agronomic decisions by farmers in EC. To assess season parameters, thirty four years of daily rainfall was collected from the University of Fort Hare Research station and used to conduct the rainy pentad (5 day rainfall totals) analysis and the daily rainfall analysis using INSTAT software programme. Based on the pentad analysis, results showed that Alice does not have a rainy season in 1 out of 2 years (50% probability) but has one in 1 out of 4 years (25% probability level). This criterion proved to be harsher and conservative when compared to the daily rainfall approach which is more precise in measuring trends on season parameters. The daily rainfall analysis indicated a 65% feasibility for the dry land cropping systems in the EC. The pentad analysis however was effective in illustrating seasonality and it showed that the wet season begins on the 1st of November, ending on the 22nd of March lasting for 140 days. Though the season duration appeared too long, the existence of dry spells during critical growth stages adversely affects the quality of the season. The daily rainfall analysis also managed to derive a signal which can guide planting decisions. For planting to be successful, this analysis determined that 20 mm of rain should be received in two consecutive days after the 1st of November. A screening trial for cover crop biomass production and weed suppression was conducted on-station Fort Hare Research Farm (32°46' S and 26° 50' E), and Msobombvu village (MSBV) (32°44' S, and 26° 55' E) over two seasons (2007/08 and 2008/09). Six summer cover crops i.e. cowpea (Vigna unguiculata), dolichos lablab (Dolichos argenteus), sunnhemp (Crotalaria juncea), buckwheat (Fagopyrum sagittatum), forage sorghum (Sorghum bicolor) and sunflower (Helianthus annus) were evaluated for biomass yield, and weed suppression. Decomposition rates, moisture conservation and residual effects of these cover crops on the succeeding main crop were also evaluated under dryland conditions. The screening trial was laid in randomized complete block design replicated three times. Forage sorghum (Sorghum bicolor) and sunflower (Helianthus annus) were identified as high biomass producers and their dry matter yields ranged from 8 -12 t ha-1. These cover crops can be useful in generating high biomass in rainfed cropping systems in the EC. Other cover crops produced 3 - 4 t ha-1 of biomass which fell short of the 6 t ha-1 expected benchmark. However, these biomass yields were important in weed management since all cover crop species showed a similar degree of weed suppression which surpassed the weed fallow treatment. As dead mulches, the cover crops failed to show residual moisture conservation and weed control benefits for the succeeding maize crop mainly because of poor residue persistence, and low harvestable fallow rainfall. Buckwheat (Fagopyrum esculentum), was selected for further investigations in a follow up trial on station in 2008/09 season because of its weed smothering qualities, suitability to short cycle rotations, and possible allelopathic properties. The trial aimed at finding weed and cost effective management options of buckwheat that are none detrimental to the succeeding maize crop. Results showed that cropping systems where buckwheat is followed by a main crop may not work as they are unprofitable with respect to R100 rand invested. Though perceived to have allelopathic properties, buckwheat failed to demonstrate the possibilities of allelopathic action against weeds. Intercropping trial was conducted on-station in 2007/8-2008/09 seasons to try and find better ways of fitting legume cover crops into maize based cropping systems without compromising production of staple cereals on limited landholdings. The trials evaluated three factors in factorial combination, cover crop planting date, intercropping strategy, and cover crop species. The trial was laid as 2 x 2 x 3 factorial arranged in a split-split plot design. The main plot factor was cover crop planting date, cover crops simultaneously planted with maize and cover crop planted two weeks after planting maize (DKC 61-25). The sub-plot factor was intercropping strategy, strip intercropping and betweenrow intercropping. The sub-sub-plot factor was cover crop species, Dolichos lablab (Dolichos argenteus (Highworth), and Cowpea Vigna ungiculata (Agrinawa) plus control plots of sole maize. Results showed that same time planting of leguminous cover crops with maize using the in-between row intercropping patterns can derive appreciable system biomass (maize/cover crop) yields, utilize land efficiently whilst getting favourable maize grain yield. Based on the rainfall analysis, results showed that the probability of success when relay seeding cover crops after two weeks into standing maize is low (15% chances of success). This suggests that relay intercropping strategies would not work due to the unavailability of a good quality season.

The CA systems were engaged through cover cropping to address land degradation problems by emphasizing high biomass production in order to realize short term benefits such as moisture conservation, weed suppression and soil fertility benefits under rainfed conditions in the central region of the Eastern Cape province. Since rainfall is the most limiting factor to crop production in the EC, a within season rainfall distribution analysis was conducted to expose the quality of the season (onset, end and duration) and hence the feasibility of CA systems to guide agronomic decisions by farmers in EC. To assess season parameters, thirty four years of daily rainfall was collected from the University of Fort Hare Research station and used to conduct the rainy pentad (5 day rainfall totals) analysis and the daily rainfall analysis using INSTAT software programme. Based on the pentad analysis, results showed that Alice does not have a rainy season in 1 out of 2 years (50% probability) but has one in 1 out of 4 years (25% probability level). This criterion proved to be harsher and conservative when compared to the daily rainfall approach which is more precise in measuring trends on season parameters. The daily rainfall analysis indicated a 65% feasibility for the dry land cropping systems in the EC. The pentad analysis however was effective in illustrating seasonality and it showed that the wet season begins on the 1st of November, ending on the 22nd of March lasting for 140 days. Though the season duration appeared too long, the existence of dry spells during critical growth stages adversely affects the quality of the season. The daily rainfall analysis also managed to derive a signal which can guide planting decisions. For planting to be successful, this analysis determined that 20 mm of rain should be received in two consecutive days after the 1st of November. A screening trial for cover crop biomass production and weed suppression was conducted on-station Fort Hare Research Farm (32°46' S and 26° 50' E), and Msobombvu village (MSBV) (32°44' S, and 26° 55' E) over two seasons (2007/08 and 2008/09). Six summer cover crops i.e. cowpea (Vigna unguiculata), dolichos lablab (Dolichos argenteus), sunnhemp (Crotalaria juncea), buckwheat (Fagopyrum sagittatum), forage sorghum (Sorghum bicolor) and sunflower (Helianthus annus) were evaluated for biomass yield, and weed suppression. Decomposition rates, moisture conservation and residual effects of these cover crops on the succeeding main crop were also evaluated under dryland conditions. The screening trial was laid in randomized complete block design replicated three times. Forage sorghum (Sorghum bicolor) and sunflower (Helianthus annus) were identified as high biomass producers and their dry matter yields ranged from 8 -12 t ha-1. These cover crops can be useful in generating high biomass in rainfed cropping systems in the EC. Other cover crops produced 3 - 4 t ha-1 of biomass which fell short of the 6 t ha-1 expected benchmark. However, these biomass yields were important in weed management since all cover crop species showed a similar degree of weed suppression which surpassed the weed fallow treatment. As dead mulches, the cover crops failed to show residual moisture conservation and weed control benefits for the succeeding maize crop mainly because of poor residue persistence, and low harvestable fallow rainfall. Buckwheat (Fagopyrum esculentum), was selected for further investigations in a follow up trial on station in 2008/09 season because of its weed smothering qualities, suitability to short cycle rotations, and possible allelopathic properties. The trial aimed at finding weed and cost effective management options of buckwheat that are none detrimental to the succeeding maize crop. Results showed that cropping systems where buckwheat is followed by a main crop may not work as they are unprofitable with respect to R100 rand invested. Though perceived to have allelopathic properties, buckwheat failed to demonstrate the possibilities of allelopathic action against weeds. Intercropping trial was conducted on-station in 2007/8-2008/09 seasons to try and find better ways of fitting legume cover crops into maize based cropping systems without compromising production of staple cereals on limited landholdings. The trials evaluated three factors in factorial combination, cover crop planting date, intercropping strategy, and cover crop species. The trial was laid as 2 x 2 x 3 factorial arranged in a split-split plot design. The main plot factor was cover crop planting date, cover crops simultaneously planted with maize and cover crop planted two weeks after planting maize (DKC 61-25). The sub-plot factor was intercropping strategy, strip intercropping and betweenrow intercropping. The sub-sub-plot factor was cover crop species, Dolichos lablab (Dolichos argenteus (Highworth), and Cowpea Vigna ungiculata (Agrinawa) plus control plots of sole maize. Results showed that same time planting of leguminous cover crops with maize using the in-between row intercropping patterns can derive appreciable system biomass (maize/cover crop) yields, utilize land efficiently whilst getting favourable maize grain yield. Based on the rainfall analysis, results showed that the probability of success when relay seeding cover crops after two weeks into standing maize is low (15% chances of success). This suggests that relay intercropping strategies would not work due to the unavailability of a good quality season.

- Description: Training is widely conducted in organizations and is actively encouraged by the recent legislation in South Africa. Millions of Rands are spent building human resource capabilities. Organizations therefore need to know whether this investment in training is bearing fruit in terms of changes in individual performance and overall impact on service delivery. The need to improve Transversal Training Management Agency (TTMA) training programmes and skills development impact to government departments has triggered the survey. Three interdependent themes are explored: training evaluation in `government departments, influence of non-training factors and human dynamics between stakeholders in the training evaluation process. Structured questionnaires, based on best practises in literature were administered to key stakeholders involved in TTMA training programmes. Training managers and the Office of the Premier (OTP) Human Resource Development (HRD) officials were interviewed, while supervisors, trainees and trainers verified the data by post. Data were collected from the Department of Basic Education, Eastern Cape (EC), TTMA trainers and trainees. Findings show that The Department of Basic Education in the EC does not fully follow a system’s approach. Evaluations done during classroom sessions focus mainly on the reaction of participants to training and not on the behaviour change in the workplace. Training participants are not prepared for training; sometimes they do not even know why they attend training. Some trainees go to training just to get certificates that increase their CV’s for promotion purposes or to run away from the stressful work environment and not for individual growth. Recommendations to use a systemic evaluation approach and involvement of trainees in their career development process are made. Further research is recommended on the managing of non-training factors that impede learning transfer.

- Description: The application of internet marketing techniques has been widespread in the hospitality sector worldwide, with many hotels crafting websites for marketing purposes. However, there is still a debate and speculation on the impact of internet marketing on business performance and profitability. Given the well-recognised value of internet marketing in the hospitality and tourism industry, this study sought to examine the impact of internet marketing on the profitability of the hospitality sector in South Africa and to establish factors which influence internet marketing usage. In order to achieve these objectives, a perceptual survey was conducted in graded hotels and lodges in the Eastern Cape province of South Africa. Multiple linear regression analysis and hierarchical regression analysis were used to determine the relationship between internet marketing and business profitability as well as the relationship between organisational and environmental factors and internet marketing usage. Based on the findings of this study, it is concluded that the use of internet marketing can positively influence business profitability. It is also concluded that internet marketing experience moderates the relationship between internet marketing usage and business profitability. The results also indicate that factors such as technological competence, managerial support, level of star grading and alliances significantly influence internet marketing usage. Thus, from the findings of this study, it was concluded that hotels and lodges can enhance their profitability through internet marketing usage.

- Description: Medicinal plants have been used as traditional medicine in the treatment of numerous human diseases for thousands of years in many parts of the world. In the developing world, especially in rural areas, herbal remedies continue to be a primary source of medicine. Scientifically, medicinal plants have proven to be an abundant source of biologically active compounds, many of which have already been formulated into useful therapeutic substances or have provided a basis for the development of new lead molecules for pharmaceuticals. Antibiotic resistance, undesireable side effects and expences associated with the use of combination therapy in the treatment of Helicobacter pylori infections have generated a considerable interest in the study of medicinal plants as potential sources of new drugs against this organism. The high complexicity of bioactive compounds accumulated in plants coupled with their broad antimicrobial activity may make it difficult for pathogenic organisms, including H. pylori to acquire resistance during treatment. This study therefore evaluates the antimicrobial potential of selected South African medicinal plants employed in the treatment of H. pylori-related infections, and the subsequent isolation of the plant active principles. An ethnobotanical survey of plants used in the treatment of H. pylori-related infections was conducted in the study area. Crude extracts of Combretum molle, Sclerocarya birrea, Garcinia kola, Alepidea amatymbica and 2 Strychnos species were screened against 30 clinical strains of H. pylori and 2 standard control strains (NCTC 11638 and ATCC 43526). In the preliminary stages of this study, ethyl acetate, acetone, ethanol, methanol and water extracts of the plants were tested against H. pylori by agar well diffusion and micro broth dilution methods. The plant crude extracts that exhibited anti-H. pylori activity with a iv percentage susceptibility of 50 percent and above were considered for the rate of kill assays and the most active crude extracts selected for bio-assay guided isolation of the active ingredient. Preliminary fractionation of the crude extract was achieved by thin layer chromatography (TLC) using different solvent combinations; hexane/diethylether (HDE), ethyl acetate/methanol/water (EMW) and chloroform/ethyl acetate/formic acid (CEF) in order to determine the most suitable combination for column chromatography (CC) and subsequent testing by indirect bioautography. The extract was then fractionated in a silica gel column using previously determined solvent combinations as eluent. Active fractions obtained from column chromatography separations were further fractionated and the compounds identified by gas chromatography/mass spectrometry (GC/MS) analysis. All the plants exhibited antimicrobial activity against H. pylori with zone of inhibition diameters ranging from 0 - 38 mm and minimum inhibitory concentration (MIC) values ranging from 0.06 - 5.0 mg/mL. The most active plant extracts were the acetone extract of C. molle with a percentage susceptibility of 87.1 percent, acetone and aqueous extracts of S. birrea (71 percent each) and the ethanolic extracts of G. kola (53.3 percent). Except for the aqueous extract, these extracts also exhibited a strong bactericidal activity against H. pylori at different concentrations. TLC analysis revealed the presence of 9 components in the acetone extract of S. birrea with the EMW solvent system as opposed to 5 and 8 with HDE and CEF respectively. Bioassay-guided isolation led to the identification of 52 compounds from the acetone extract of S. birrea with n-octacosane being the most abundant (41.68 percent). This was followed by pyrrolidine (38.91 percent), terpinen-4-ol (38.3 percent), n-eicosane (24.98 percent), cyclopentane (16.76 percent), n-triacontane (16.28 percent), aromadendrene (13.63 percent) and α-gujunene (8.77 percent). Terpinen-4-ol and pyrrolidine demonstrated strong antimicrobial activity against H. pylori at all concentrations tested. These results may serve as preliminary scientific validation of the ethnomedicinal uses of the above mentioned plants in the treatment of H. pylori-related infections in South Africa. Terpinen-4-ol and pyrrolidine could be considered for further evaluation as therapeutic or prophylactic agents in the treatment of H. pylori-related infections. However, further investigations would be necessary to determine their toxicological properties, in-vivo potencies and mechanism of action against H.pylori

- Description: To realise the dream of the African Renaissance and a better life for all South Africans, the entrepreneurial energies of all people, including children, should be harnessed to contribute towards economic development, job creation and poverty alleviation. Entrepreneurship creates wealth and results in economic prosperity for a country. However, in South Africa, entrepreneurship still remains a dream yet to be realised. This is supported by the findings of Maas and Herrington (2006), who identified entrepreneurial activity in South Africa to be very weak as evidenced by a low Total Entrepreneurial Activity (TEA) rate. Youths are not engaging in entrepreneurial activity and are making the bulk of the unemployed in South Africa. The primary objective of this study was to investigate the perceived triggers and barriers to youth entrepreneurship in South Africa. Two sets of questionnaires were self- administered to high school students and university students. The respondents which consisted of three hundred and twenty three university students and two hundred and fifty six high school students, were selected using simple random sampling method. Five point Likert scale was used to measure the responses. Descriptive as well as inferential statistics were used to analyse the data. The results indicated that youth entrepreneurial intention is low in South Africa. The results also indicated that students perceived mainly extrinsic rewards, market opportunities as well as intrinsic rewards as the three top triggers towards entrepreneurial intention. Independence/autonomy and capital were also regarded as triggers to entrepreneurial intentions. The barriers to youth entrepreneurship included lack of capital, skill and support as well as lack of market opportunities and risk. The study recommends that in order to encourage youth entrepreneurial intentions, government and all stakeholders should ensure that all the perceived triggers are made available. In addition, the barriers to youth entrepreneurship should be minimised. , Thesis (MCom) -- Faculty of Management and Commerce, 2011
