- Description: This study examines the effects of energy poverty on sustainable development in Zimbabwe. The principal objective of this study was to analyse Zimbabwe energy poverty as a contributing factor impacting on sustainable development. Access to energy was viewed as a human right in this study and attributes of ecological modernization and energy ladder theories were incorporated in the study so as to foster sustainable development. The study developed a symbiosis between energy poverty and human development in Zimbabwe. The power shortages have caused a lot of energy poverty and load shedding in the country and this has had adverse consequences on the transformation of the economy as well as the general human capacity development in the country. The supply shortage was as a result of many factors which include the lack of investment in the power sector by government for expanded generation capacity, ageing equipment, incorrect pricing, bad debts, droughts, internal conflicts, skills flight, and government energy sector regulation, vandalisation of equipment and under supply of coal to thermal power stations. The country needs to commit itself towards improving the current situation by revising the energy policy to include alternative sources, the integration of regional power systems and construction of more power stations, and by putting research monitoring and evaluation mechanisms in place so as to improve power generation capacity which meets the demand of the country. The evidence from the findings gathered in this study led to the conclusion that the Zimbabwe energy and power sector lacks the capacity to provide adequate reliable clean energy to the nation and this has affected the development of the country.

- Description: Reading is a skill that teachers have to enthusiastically teach to encourage learning of complex set of reading skills, knowledge and understanding. Teaching of reading strategies to students to improve their reading ability is very important. However, surveys conducted in South Africa during 2001 and 2004 by the Department of Basic Education to establish literacy and numeracy levels in primary schools showed shockingly low levels of reading ability across the country. Therefore, the purpose of this study was to ascertain English First Additional Language teachers’ understanding and implementation of reading strategies. Obtaining teachers’ perceptions and challenges on reading strategies was vital for this study as a way of establishing their competency towards teaching reading. Four research questions were sought to determine namely; reading strategies currently adopted by teachers in their classes, teachers’ perceptions of reading strategies, reading problems or challenges that teachers were facing. A mixed method research was chosen for this study which involves both the qualitative and quantitative approaches. The study followed a survey research design and a case study research design. A purposive sampling was used to select 126 teachers from which questionnaires were administered to collect data and 10 teachers were randomly drawn from the sample to be interviewed and observed in class. Both qualitative and quantitative data were analysed concurrently using coding and categorization of themes for qualitative data and Statistical Package for Social Sciences (SPSS) for quantitative data. The results indicated that a majority of teachers seemed not to understand and implement certain reading strategies and there were few teachers who asserted to the understanding and implementation of these strategies. The teachers mentioned that they were not trained continuously on reading strategies and the schools had no libraries. A majority of teachers highlighted that there were indeed problematic reading strategies and they simply did away with the strategies that were not suitable for their learners and would try the ones they found relevant or suitable. The study presents a proposed reading enhancement model to assist teachers in the teaching of reading. English First Additional Language teachers may benefit from the model and incorporate some or all of the aspects to develop their reading strategy use programmes.

- Description: Contextualized in the South African Language in Education Policy (LiEP) and the Curriculum and Assessment Policy Statement (CAPS), the study aimed at investigating the writing competency of EFAL Grade 12 learners in the two rural public schools. It was the researchers‘ hunch that the learners‘ socio-cultural conditions at which they learn EFAL are not taken into consideration by teachers and that hampers or impedes the development of language and writing. Further, the research sought to unearth the strategies and techniques used by teachers to teach writing in EFAL, and whether these facilitate the development of writing competency, that enhances better performance in other Grade 12 subjects taught through English as a Language of Learning and Teaching (LoLT). The study is informed by the socio-cultural theory, language acquisition theories, and the language learning theories. The study also drew from the writing strategies, writing in the curriculum, and second language learning discourses Framed in the interpretive paradigm and the qualitative approach, the research adopted a case study design. The sample of the study comprised of seven teachers of which two were EFAL teachers and five of these teach content subjects. Twenty four Grade 12 learners constituted the four Focus Groups. The data collection tools comprised of interviews, Focus Group Discussions (FGDs), observation and document analysis. Learners wrote essays and free writing exercises which formed transcripts for document analysis. The purposively selected teachers and the Grade 12 learners were granted interview questions in advance. The collected data was analysed and put under themes as determined by the study‘s research questions. Such themes included; challenges faced by learners when writing in EFAL, strategies used by teachers in teaching writing , perceptions of teachers and learners on learners‘ writing competency and the connection or linkage between learners‘ writing competency in EFAL and content subjects. Learners‘essays and free writing revealed that the learners have limited vocabulary in their FAL. Furthermore, the study made known that learners experience anxiety when they have to answer questions in English and that results in them being incompetent in writing in the target language. Other hindrances to EFAL writing that were revealed by the study included the detrimental effect of social media on the writing competency and lack of motivation to read for writing in English. In addition, the study established that there were teaching approaches that were employed by teachers when teaching writing which included the process writing and integration. Content subject teachers made known to the study that they were not teaching writing to the learners but assess them in essay writing and summaries as required by the school-based assessments in their respective subjects. It was also disclosed in the study that writing encompasses other language skills especially reading. The study also revealed that writing is a skill that is obligatory to be taught because it becomes beneficial to other subjects and that it enhances learners‘ writing for a variety of reasons. Overall, the study made known that there are complex circumstances that Grade 12 learners in rural public schools encounter when engaging in writing in the EFAL. The study concluded that although English could be perceived as a dominant language, it is embedded with multiplicity of challenges in the rural secondary schools where it is used as a LoLT. Such hindrances mostly find expression when learners have to engage in writing activities and encompass; lack of motivation, anxiety, limited vocabulary and the influence of social networks. The study recommended that the EFAL policy makers should not use a blanket approach on how EFAL should be taught but consider the demographic situations of the various sections of South Africa. The study also recommended that code switching which is practiced in bilingual classrooms appears inevitable and therefore should be formalized.

- Description: There have been several attempts by the South Africa government to improve the agricultural productivity on smallholder farms since the end of apartheid. In spite of the government support, agricultural productivity has stagnated for several years across the Eastern Cape rural communities including Mthatha and Qamata. The aim of this study was to understand the roles played by irrigation adoption and market participation in addressing poverty reduction and shared prosperity levels of smallholder farmers in Eastern Cape of South Africa. Data were collected using purposive and random sampling approach through the use of the snowball method. To collect data, a questionnaire was designed and administered through face-to-face interviews. Overall, 200 farmers were interviewed both at Mthatha and Qamata irrigation scheme to represent the farmers in the area. The collected data were analysed using both parametric and non-parametric methods. The non-parametric methods used include descriptive analysis, estimation of gross margins as a proxy for profitability. The Stochastic Frontier Analysis (SFA), Binomial Logistic Regression (BLR), Ordinary Least Squares (OLS), tobit censored regression and propensity score matching (PSM) were the parametric methods used in the study. Profit efficiency was measured using the normalized transcendent logarithmic profit frontier approach (Cobb-douglas). Stochastic Production Frontier (SPF) technique was used to determine the technical efficiency of individual farmers and to identify the major factors that influence technical efficiency. Binomial logistic regression was used to determine factors affecting irrigation adoption and market participation among smallholder farmers. OLS was used to estimate the impact of institutional characteristics, socio-economic and agronomic factors on smallholder farmers’ level of market participation for selected crop enterprises. Lastly, tobit regression and propensity score matching (PSM) analyses were used to estimate the impact of irrigation technology adoption on poverty reduction in the province. The results of the descriptive statistics of the overall sample revealed an average age of 61 years, and mean household size of 4.6 persons with majority of the household head having at least obtained some primary school education (59.5percent). Most of the household heads interviewed were men (68.5percent). Most farmers are single (65percent) with regard to their marital status. Farming is viewed as major source of livelihood for smallholders with an average income of R12523.37 for overall sample and income of R15559.80 and R5795.59 per crop season, respectively, for irrigators and non irrigators. Smallholder irrigators generated a higher gross margin of R7585.26, R21966.89 and R6266.07 from maize, cabbage and potato enterprises, respectively, compared to their non irrigator counterparts in maize (R131.39), cabbage (R10938.04) and potato (R3433.31) enterprises. The results of the frontier profit model revealed mean profit efficiency of 90percent, 99.99percent and 99.99percent, respectively, for maize, cabbage and potato.The binary logistic regression model for irrigation adoption indicated that years in school, cooperative membership, off-farm income, credit access and distance to market significantly explain smallholder farmers’ irrigation adoption decision. On the other hand, age of household head, market support, farm size, livestock income and distance to market were the key variables that accounted for smallholder farmers’ market participation adoption behaviour. The findings from the stochastic production frontier (SPF) indicate that smallholder farmers are technically efficient in maize and cabbage enterprises both at 99.99percent. Lastly, the findings from the Tobit regression and propensity score matching are consistent across the two methods, suggesting that being a member of irrigation adoption has a positive significant impact on income of smallholder farmers. Irrigation and market participation appear to have a significant and positive impact on smallholder poverty reduction (measured by crop income) for those farmers engaged in them. The findings from this study provide 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 irrigation technology and market participation.

- Description: The objective of this study was to investigate and explore the errors and misconceptions associated with the concept of fractions which are displayed by Grade 6 learners in two primary schools in the Queenstown Education District of the Eastern Cape Province. The research was done specifically to identify errors and misconceptions made by these learners in the addition and subtraction of common and mixed fractions. The study further tried to establish the causes of these errors and misconceptions. The research explored whether Cognitively Guided Instruction (CGI) can assist in the improvement or reduction of these errors and misconceptions. The study was conducted at Mlungisi and Xhalanga primary schools (pseudo – names) of the Queenstown Education District in the Eastern Cape Province. This was a mixed method research design, where 100 learners from two purposively identified primary schools were selected and subjected to a pre-test. From the 100 learners, 10 purposively selected learners were identified for interviews. The learners were also subjected to direct observations and documents (such as the Caps document, ANA examination papers, learners’ home and classwork books, November/December Grades 5 and 6 mark sheets and schedules, etc.) which were analysed and a post-test was administered. Two mathematics teachers teaching at the two primary schools were interviewed. Triangulation was used for data analysis. A Cognitively Guided Instruction was used to investigate whether the errors and misconceptions can be reduced or improved. The findings of the study were that learners do make errors when learning common fractions and that the types of errors were careless mistakes, conceptual errors, procedural errors and application errors which were identified and discussed in the study. The study further established that the Cognitively Guided Instruction approach recommended by the Curriculum and Assessment Policy Statement (CAPS) can be used to develop the learners’ conceptual understanding of common fractions. The CGI approach advocates the use of concrete materials for conceptual learning to take place. The findings of the study confirmed well documented research on the learners’ difficulties when dealing with fractions.

- Description: Early yield prediction of a maize crop is important for planning and policy decisions. Many countries, including South Africa use the conventional techniques of data collection for maize crop monitoring and yield estimation which are based on ground-based visits and reports. These methods are subjective, very costly and time consuming. Empirical models have been developed using weather data. These are also associated with a number of problems due to the limited spatial distribution of weather stations. Efforts are being made to improve the accuracy and timeliness of yield prediction methods. With the launching of satellites, satellite data are being used for maize crop monitoring and yield prediction. Many studies have revealed that there is a correlation between remotely sensed data (vegetation indices) and crop yields. The satellite based approaches are less expensive, save time, data acquisition covers large areas and can be used to estimate maize grain yields before harvest. This study applied Landsat 8 satellite based vegetation indices, Normalized Difference Vegetation Index (NDVI), Soil Adjusted Vegetation Index (SAVI) and Moisture Stress Index (MSI) to predict maize crop yield. These vegetation indices were derived at different growth stages. The investigation was carried out in the Kopanong Local Municipality of the Free State Province, South Africa. Ground-based data (actual harvested maize yields) was collected from Department of Agriculture, Forestry and Fisheries (DAFF). Satellite images were acquired from Geoterra Image (Pty) Ltd and weather data was from the South African Weather Service (SAWS). Multilinear regression approaches were used to relate yields to the remotely sensed indices and meteorological data was used during the development of yield estimation models. The results showed that there are significant correlations between remotely sensed vegetation indices and maize grain yield; up to 63 percent maize yield was predicted from vegetation indices. The study also revealed that NDVI and SAVI are better yield predictors at reproductive growth stages of maize and MSI is a better index to estimate maize yield at both vegetative and reproductive growth stages. The results obtained in this study indicated that maize grain yields can be estimated using satellite indices at different maize growth stages.

- Description: This study aimed at evaluating the contributions of two (2) selected rehabilitation centres to the goal of ameliorating the substance abuse problem in Gauteng. The study utilized a methodological triangulation approach for data collection, but with greater emphasis on qualitative methods. The study collected its qualitative data from four focus groups conducted with 32 participants and six key informants who were subjected to in-depth interviews. The quantitative aspect of the study made use of a mini-survey in which one hundred (100) questionnaires were distributed amongst the primary caregivers of recovering drug and substance abusers. The major findings of the study pointed out that rehabilitation centres were unequivocally contributing to the goal of ameliorating substance abuse in Gauteng and, by extension, South Africa. Among some of the outstanding contributions of the rehabilitation centres was the provision of a non-judgmental and supportive therapeutic environment for clients to recover. It was also observed that rehabilitation centres were acting as character reformatories for substance abusers, and, thus, aiding their easy reintegration back into their families, societies and work places. The study also found out that the selected rehabilitation centres were providing ample admission periods and competent counselling services for their clients to navigate their way to recovery. The study unearthed new trends in the substance abuse landscape of Gauteng. Firstly, it was established that more educated people were falling into substance abuse usage. Secondly, the drugs which were rendering users more amenable to rehabilitation were noted to be highly potent. The high potency was noted to be responsible for extreme difficulties in withdrawal and rehabilitation. This was, therefore, noted to accentuate the imperativeness of the role and contributions of rehabilitation centres in helping drug users to achieve recovery in an environment that was supportive, nurturing and safe. It is, therefore, on the basis of these fundamental findings that this study concluded that the contributions of rehabilitation centres were not only important in the fight against drug and substance abuse, but were also a necessary precondition in this endeavour. Conversely, it was established that the contributions of the rehabilitation centres were being thwarted by exorbitant and extortionate treatment fees charged by the rehabilitation centres. More so, rehabilitation centres faced the dire challenge of poor visibility due to the poor marketing of services, as well as their location in affluent or remote areas which are mainly accessible only through private transport. This means that some people, especially the rural and the urban poor, were not equitably benefiting from the services of the rehabilitation centres. The study observed that women, girls and children in general were largely excluded from benefiting from the services of the rehabilitation centres. The research closed off by recommending to rehabilitation centres that they ought to address administrative gaps such as embracing and practising social, linguistic, dietary and gender sensitivity in their programmes to ensure that they remain relevant to their clients while also reflecting the diversity in South Africa. Recommendations were also made to the government to intervene and moderate the pricing of substance abuse treatment services, by making them reflect the country’s socioeconomic inequalities.

- Description: This study aimed at evaluating the contributions of two (2) selected rehabilitation centres to the goal of ameliorating the substance abuse problem in Gauteng. The study utilized a methodological triangulation approach for data collection, but with greater emphasis on qualitative methods. The study collected its qualitative data from four focus groups conducted with 32 participants and six key informants who were subjected to in-depth interviews. The quantitative aspect of the study made use of a mini-survey in which one hundred (100) questionnaires were distributed amongst the primary caregivers of recovering drug and substance abusers. The major findings of the study pointed out that rehabilitation centres were unequivocally contributing to the goal of ameliorating substance abuse in Gauteng and, by extension, South Africa. Among some of the outstanding contributions of the rehabilitation centres was the provision of a non-judgmental and supportive therapeutic environment for clients to recover. It was also observed that rehabilitation centres were acting as character reformatories for substance abusers, and, thus, aiding their easy reintegration back into their families, societies and work places.

- Description: The number of orphaned and vulnerable children in South Africa is drastically increasing which leads to most children being put in a foster care system. Yet there are great lacunae within its implementation; facilitation and monitoring which effectively affect the children involved. This evoked interest to the researcher on evaluating the effects of foster placement on childhood development; a study of Berlin Location, Buffalo City Municipality. The study intended to fulfil the following objectives: 1. To document environments that challenges foster care placement as an intervention of child placement; 2. To understand the negative impacts of foster care on a child’s psychosocial development; 3. To explore the impact of host parent’s culture to the child’s adaptation; 4. To establish the strengths and weaknesses of the South African child protection system. The study utilized qualitative paradigms guided by the qualitative research approach by adopting a case study cum phenomenological design. It employed in-depth interviews, focus groups, key informants as data collection methods. The study used both non-probability and probability sampling methods of which purposive and simple random sampling technique was utilised. The population of study was made up of twenty (20) participants who were incorporated of five (5) foster parents, five (5) key informants and ten (10) foster children. The data was analysed qualitatively through content thematic analysis. The study revealed the following findings: (i) challenges pertaining to adjustment to home milieu, (ii) lack of knowledge on foster parents’ rights and responsibilities, (iii) inadequateness of foster grant, (iv) cultural deviance, (v) prevalence of drug use and teenage pregnancy, (vi) dire lack of awareness raising sessions for the foster parents and their children, (vii) identity crisis disposition displayed by foster children, (viii) lack of individualizing cases of foster care placement by the social workers, (ix) efficiency of alternative care in comparison to residential care, (x) internalization of emotions by foster children, (xi) continued void for the biological mother’s love and affection,(xii) paucity of monitoring services to children, (xiii) information sharing and capacity building workshops for social workers a prerequisite, (xiv) Effectiveness of authoritative parenting a successful method and difficulty with telling foster children about their background. The study findings made the following recommendations: Strengthening inter-sectoral relationships and capacitate different stakeholders; Emphasis on early intervention and preventative programmes; Enforcement of punishment measure for incompliance; Implementation of training for foster parents and children; Foster care process made a specialization for social workers, Government to invest on psychosocial support and capacitating workshops for social workers. The researcher, therefore, hopes to have fulfilled the study objectives and further explored all the requirements of the study during data collection.

- Description: Geological and geophysical methods were used to investigate the Karoo area extending from longitudes 25.50 E to 27.50 E and latitudes 300 S to 330 S in South Africa, particularly Fort Beaufort, Aliwal North, Venterstad and Smithfield. The geology of the area is dominated by the upper Beaufort Group (Adelaide Subgroup) with an extensive network of dolerite sills and dykes that intruded the sedimentary sequence. A relationship between neotectonics, post-Karoo tectonics, groundwater and lithology was investigated to locate suitable groundwater potential sites. Apart from studying the role of neotectonics and the post Karoo tectonics, this research aims at generating groundwater targets to alleviate water shortages mainly for farming and livestock, and prove that neotectonics is still active. Methodologies adopted for obtaining these results included a comprehensive literature review, thin section analysis, scanning electron microscopy, geophysical investigation (magnetic, gravity, and vertical electrical sounding), and the application of Geographical Information Systems (GIS) and remote sensing. Twenty samples were collected at various locations within the study area and were analyzed using the petrographic microscope while others were analyzed with the Scanning Electron Microscopic (SEM) combined with an Energy dispersive x-ray spectrometry. The results show that the rocks are fractured, porous and have variable mineralogy (presence of heavy minerals) within the rocks. The use of Geographical Information Systems (GIS) and remote sensing in geological surveys, especially hydrogeology, has gained momentum over the past few years. This research is no exception as ArcMap software was used to create a map of seismic epicentres of the Eastern Cape Province. From the map it can be observed that seismicity still occurs and thus leading to the notion of neotectonics being active. Lineaments were also automatically extracted using the ENVI 5.1 and Geomatica 2013 software. Lineaments are zones of weakness in the subsurface of the Earth and are very important in locating groundwater potential sites. Geophysical techniques are essential and highly accurate for groundwater studies. Gravity and magnetic techniques were applied on data which was supplied as grids. Analysis using Geosoft Oasis 8.3 revealed extensive lineaments and ring like patterns and these were inferred to be dolerite intrusions (sills and dykes). The morphology of the intrusions help in identifying possible groundwater potential zones and thus they should be investigated. Vertical electrical sounding (VES) technique using the Schlumberger array was carried out at three sites (Fort Beaufort fracture which is possibly related to Quaternary surface uplift of the Amatole-Swaziland axis, splay of the Fort Beaufort fracture and at a site which showed high groundwater potential) to explore subsurface layering. IP2win (lite), 1-D modelling software was used to model the apparent resistivity data to obtain the geoelectric parameters of the subsurface (thickness and resistivity). The VES results are consistent with fractured rocks that aid groundwater movement. The VES data for the three sites was further modelled by the RES2DINV software and this shows low resistivity values associated with loose, water saturated top sandy soil and higher resistivity values associated with sedimentary sequences and dolerite. Moreover, potential sites for citing wells are predicted to be between 79.5 and 128 m on the profile. Further neotectonic studies need to be done, especially on the quaternary sediments as they would have more neotectonic evidence. The use of geophysical techniques for groundwater search need to be intensified, with more emphasis being put to the sedimentary sequences bordered by dolerite intrusions and fractured zones.

- Description: Self-efficacy in clinical performance is a very important aspect in quality of health care, because it is the ability of the person to produce the desired outcomes. The aim of the study was to evaluate self-efficacy in clinical performance of NIMART programme by professional nurses in Buffalo City Metropolitan in Eastern Cape Province South Africa. A quantitative, descriptive survey design was used to examine self-efficacy in clinical performance during implementation of NIMART programme. A purposive sample of 358 NIMART programme trained professional nurses was included in the study. Analysis of the finding was done using SPSS version 21.0. Descriptive statistics (frequencies, percentage, mean and standard deviations) were used to analyse categorical variables. To reduce data volume, factor analysis was used to identify six variable clusters: Evaluation; planning, assessment, implementation, and patient care mentoring. Factor 1 (evaluation) was highly loaded on patient driven results (0.63); nursing interventions (0.70); breakdown point location (0.80); prognosis based care decisions (0.79); prognosis based outcome monitoring (0.70); and prognosis based settings adjustment (0.70). These items collectively define evaluation of self-efficacy clinical performance of the participants. Factor 2 (planning) was termed planning of patient care in a clinical setting was significantly loaded on these items: data driven nursing diagnosis (0.51); patient driven nursing diagnosis (0.52); settings based nursing diagnosis (0.49); overall care plan formulation (0.52); short-term patients care formulation (0.58); long-term patient care formulation (0.66); goal based measurable outcomes (0.80); goal based daily patient care plan (0.79); settings based daily patient care plan (0.73). Factor 3 (assessment) which was termed assessment in clinical performance was not significantly loaded in some of the items: physical assessment (0.64); patient history (0.65); energy restoration (0.56); time management (0.71); objective patient health data (0.61); subjective patient health data (0.49); data collection documentation (0.44). Factor 4 (implementation) data source correlation; patient health data analysis (0.45); patient strength (0.46); nurse-patient/family communication (0.55); nurse patient collaboration (0.64); Experience driven decision making (0.58). Factor 5 (patient care) patient care plan adherence (0.65); setting based overall patient care (0.74); resource based overall patient care (0.59). Factor 6 (mentoring) patient’s concerns identification (0.48); patient problems prioritisation (0.46); mentor/colleague advice (0.43); mentor/colleague feedback use (0.61); patient discharge strategies (0.71); continuous reporting/documenting (0.63). The mean scores produced by the Kruskal-Wallis test showed the lowest scoring pattern as follows: 20122013201120142010. This order was the same for all the variables, confirming that the 2010 group scored significantly higher than any other group on all the variables. The overall results of the study revealed that professional nurses have high self-efficacy in clinical performance in implementation of NIMART programme, except in evaluation aspect of self-efficacy where they scored lessor. Professional nurses trained by FPD scored higher in the aspects of self-efficacy in clinical performance compared to RTC trained; but scored lower in evaluative ability of self-efficacy in both institutions (FPD and RTC). The findings of this study showed that the overall self-efficacy of the professional nurses trained on NIMART programme performed clinically satisfactorily. It is recommended that in-service education or continuous professional development for professional nurses working in PHC’s should not only concentrate on updating clinical skills, but also create opportunity for reflection and strengthening of professional nurses’ self-efficacy in clinical performance. Also, further study on other processes of goal realisation will aid our understanding of self-efficacy in achieving the desirable goals of the professional nurses for patient quality care. Further research is also needed to evaluate clients’ satisfaction during care based on the NIMART intervention programme.

- Description: Emerging organic contaminants (EOCs) have been the focus of global environmental research for over three decades. EOCs have caused widespread concern due to their extensive use. As EOCs were designed to correct, enhance or protect a specific physiological, their target effects in humans and/or farm stocks are relatively well known and documented. However, there is limited knowledge about their unintended effects in the environment. To address the occurrence, distribution and fate of EOCs in the environment, efficient and reliable analytical methods are needed. The relatively low concentration, high polarity, and thermal lability of some EOCs, together with their interaction with complex environmental matrices, make their analysis challenging. Sample preparation followed by GC or HPLC separation and mass spectrometry (MS) detection has become the standard approach for evaluating EOCs in environmental samples. Physicochemical properties of EOCs range from highly water-soluble (hydrophylic) to highly water-insoluble (hydrophobic). Two groups of these EOCs were considered for study in this work. Pharmaceutical and personal care products (PPCPs) were comprehensively studied in five wastewater treatment plants and their receiving watersheds in Amathole districts in Eastern C ape, South Africa. PPCPs have been widely reported in wastewater influents, effluents, receiving rivers and biosolids, but reports of their occurrence in all these matrixes have been limited by the difficulty of analysis. Therefore, a comprehensive validation of methods was carried out on the influents, effluents, sludge and soil from the irrigated golf course where the effluent of one of the study sites was being used for over three decades now for irrigation. In all, thirteen PPCPs from five therapeutic groups were selected for study in this work because of their administering rate and availability of analytical instrument. Good limit of detection (LOD) and limit of quantification (LOQ) were achieved for the method used. The LOD for the aqueous Three different technologies were employed for the treatment of wastewater in the five selected wastewater treatment plants (WWTPs) and study was carried out to evaluate their ability to eliminate the selected compounds from the influents to the effluents using statistical analysis (ANOVA) at p<0.05 on the percentage removal rate across the three plants. The results had shown eight of the compounds having no significant difference among the treatment operations, whereas the remaining five compounds varied significantly among the treatment technologies under investigation. Principal component analysis was performed on the concentration of PPCPs, their removal rate and also on the physicochemical and treatment operation parameters. Hydraulic retention time (HRT) had correlation coefficient, r = 0.90 with the concentration of PPCPs and removal rates. Furthermore, occurrences, seasonal variation, mean concentration distribution pattern of the compounds, and temporal evaluation of the mean concentration of the pharmaceutical compounds in the five WWTPs during one year of sampling were considered. The results revealed that five products which were diclofenac, ibuprofen, paracetamol, triclosan and diethyl toluamide (DDET) were predominant among the PPCPs in all the WWTPs. The removal efficiency was highest in caffeine with 96 percent, and the lowest was obtained with carbamazepine (4 percent). Risk quotient of the concentration of PPCPs in the effluents and receiving waters was determined to assess their chronic toxicity at three trophic levels: fish, algae and matrixes studied ranged from 0.01 μg/L to 0.25 μg/L, and the LOQ from 0.02 μg/L to 0.78 μg/L. In the solid matrixes, LOD varied from 0.01 ng/g to 0.65 ng/g, and the LOQ between 0.08 ng/g and 5.17 ng/g. Better recovery efficiency was obtained with this mixture of solvents, acetone: dichloromethane (1:1), for the recovery of the five therapeutic groups in the solid matrixes using ultrasonication- assisted techniques. The results show percentage recovery values ranging from 68.8 percent to 107.5 percent diaphian. According to the environmental risk assessment results, ibuprofen and triclosan were found to be the most critical compounds due to their high risk quotient values. These findings will, therefore, help in the future evaluation of the efficiency of different treatment technologies in the removal of various PPCPs from the wastewater and their sustainable management in the aquatic resources in Eastern Cape, South Africa. For the lipophilic organochlorine pesticides (OCPs), the limits of detection (LODs) of the tested congeners varied from 0.04 ng/g (α-BHC) to 0.49 ng/g (endosulfan sulfate) and the limits of quantification ranging from 0.22 ng/g (aldrin) to 2.17 ng/g (δ-BHC).

In all, thirteen PPCPs from five therapeutic groups were selected for study in this work because of their administering rate and availability of analytical instrument. Good limit of detection (LOD) and limit of quantification (LOQ) were achieved for the method used. The LOD for the aqueous Three different technologies were employed for the treatment of wastewater in the five selected wastewater treatment plants (WWTPs) and study was carried out to evaluate their ability to eliminate the selected compounds from the influents to the effluents using statistical analysis (ANOVA) at p<0.05 on the percentage removal rate across the three plants. The results had shown eight of the compounds having no significant difference among the treatment operations, whereas the remaining five compounds varied significantly among the treatment technologies under investigation. Principal component analysis was performed on the concentration of PPCPs, their removal rate and also on the physicochemical and treatment operation parameters. Hydraulic retention time (HRT) had correlation coefficient, r = 0.90 with the concentration of PPCPs and removal rates. Furthermore, occurrences, seasonal variation, mean concentration distribution pattern of the compounds, and temporal evaluation of the mean concentration of the pharmaceutical compounds in the five WWTPs during one year of sampling were considered. The results revealed that five products which were diclofenac, ibuprofen, paracetamol, triclosan and diethyl toluamide (DDET) were predominant among the PPCPs in all the WWTPs. The removal efficiency was highest in caffeine with 96 percent, and the lowest was obtained with carbamazepine (4 percent). Risk quotient of the concentration of PPCPs in the effluents and receiving waters was determined to assess their chronic toxicity at three trophic levels: fish, algae and matrixes studied ranged from 0.01 μg/L to 0.25 μg/L, and the LOQ from 0.02 μg/L to 0.78 μg/L. In the solid matrixes, LOD varied from 0.01 ng/g to 0.65 ng/g, and the LOQ between 0.08 ng/g and 5.17 ng/g. Better recovery efficiency was obtained with this mixture of solvents, acetone: dichloromethane (1:1), for the recovery of the five therapeutic groups in the solid matrixes using ultrasonication- assisted techniques. The results show percentage recovery values ranging from 68.8 percent to 107.5 percent diaphian. According to the environmental risk assessment results, ibuprofen and triclosan were found to be the most critical compounds due to their high risk quotient values. These findings will, therefore, help in the future evaluation of the efficiency of different treatment technologies in the removal of various PPCPs from the wastewater and their sustainable management in the aquatic resources in Eastern Cape, South Africa. For the lipophilic organochlorine pesticides (OCPs), the limits of detection (LODs) of the tested congeners varied from 0.04 ng/g (α-BHC) to 0.49 ng/g (endosulfan sulfate) and the limits of quantification ranging from 0.22 ng/g (aldrin) to 2.17 ng/g (δ-BHC).

- Description: Pseudomonas species are Gram-negative bacteria most abundant in soil and water bodies, with the capacity to thrive in varied environments. They are largely associated with resistant pathogenic bacteria linked to human and plant diseases. Species such as Pseudomonas aeruginosa have been particularly targeted as case studies due to the extremity to which they pose a threat to human health. With more focus directed at using these species for biocontrol and bioremediation purposes, their role in bioactive compound production may be equally important. As the crisis on antimicrobial resistance still persists, the need for effective antimicrobial compounds is ever more urgent and solutions may possibly still be dormant in bacterial species whose potential has not been fully investigated. On a bid to source out potential antimicrobial compound producers, soil samples were collected from Hogback forest reserve in the province of the Eastern Cape, South Africa. For bacterial screening, M1 and R2A agar were used and the cultures grown at 37˚C for a period of seven days. After the presumed Pseudomonas species were identified, antimicrobial production was determined by submerged fermentation method using nutrient broth as media of choice. Active isolates were further studied to determine the optimum conditions which best facilitate for antimicrobial compound production, with parameters such as temperature (25˚C – 40˚C) and pH (4 – 9) considered. The role plasmids play in antimicrobial compound production was also investigated. Each isolate was grown in fermentation media containing Sodium dodecyl sulphate and Ethedium Bromide, at varying concentrations, to facilitate for plasmid curing. With each sample, distinct colonies were identified with varying pigmentations most dominant being a cream colour. The identity of the isolated strains was achieved through sequencing of 16S rDNA. Phylogenetic analysis showed that isolate A16 had 80 percent homology with Pseudomonas plecoglossicida strain P4 and share a close ancestor with isolates Y52 and Y81, also isolate Y89 showed a 90 percent homology with Pseudomonas sp. Co-11a. With the exception of isolate A16, the isolates which were active against Gram-negative bacteria lost activity as the screening processes continued. When looking at temperature variations, isolates Y81 and A16 were highly active with maximum activity observed at 35˚C while Y89 performed best at 25˚C and Y52 showed constant activity across all studied temperatures. The plasmids in all isolates were found to be 48.5 kb in size with the exception of isolate Y89 which was 20 kb. The plasmids were cured at concentrations of (1 mg/ml; 5 mg/ml; 7 mg/ml; 10 mg/ml; 11 mg/ml) SDS and (125 μg/ml; 6.5 μg/ml; 5μg/ml) EtBr. The curing process also showed changes in both the antimicrobial activity of the isolates as well as their physical characteristics. The isolates are the first reported Pseudomonas species from Hogsback forest reserve with the ability to produce antimicrobial compounds which are active against Gram-positive and Gram-negative bacteria. These mesophilic bacteria also show that plasmids do not pay any role in the production of antimicrobial compounds and that the biosynthesis genes are highly likely to be chromosomal borne meaning that the production cannot be linked to horizontal transfer of genes. Therefore, these isolated Pseudomonas species provide a potential reservoir of antimicrobial compounds which may play an important role in the antimicrobial resistance phenomenon.

- Description: Wastewater treatment facilities have been identified as potential source of surface water pollution worldwide. In this study, the physicochemical qualities and heavy metal (including Zinc, Cadmium, Iron, Lead and Copper) concentrations in the final effluents, as well as the reduction efficiencies of three municipal wastewater plants in the Eastern Cape, South Africa were evaluated from September 2015 to February 2016 using standard methods. Wastewater effluent and sludge samples were collected from the selected plants on monthly basis over a period of six months from September 2015 to February 2016. Standard analytical method (Atomic absorption spectroscopy [AAS]) was used to assess the concentration levels of heavy metals. The physicochemical parameters assessed include pH, Temperature, Total Dissolved Solid, Turbidity, Biochemical Oxygen Demand, Chemical Oxygen Demand, Alkalinity, Dissolved Oxygen, Free chlorine, Chloride, Sulphate, Phosphate, Ammonium and Electrical Conductivity. The results of the evaluation showed that temperature ranges from 19 to 36 °C, Electrical Conductivity from 60-1095 mS/m, Alkalinity from 2.6-20.9 mg/L, Nitrate from 0.24-26.5 mg/L, Nitrite from 0.01-90 mg/L, Phosphate from 0.02-5.12 mg/L, Ammonium from 0.06-112 mg/L, Sulphate from 3-72 mg/L, Chloride from 3.25-224 mg/L, Chemical Oxygen Demand from 17-394 mg/L and Turbidity from 1.96-715 NTU. Free chlorine concentrations and dissolved oxygen were within the recommended limits for most part of the sampling period and ranged between 0.17-0.48 mg/L and 0.19-21.9 mg/L respectively. The pH, Phosphate, Sulphate and Free chlorine were within acceptable limits while Electrical Conductivity, Temperature, Total Dissolved Solid, Turbidity, Chemical Oxygen Demand, Chloride, Ammonium, Nitrate and Nitrite were not within specified limits. The reduction efficiencies observed generally ranged between 43.9 and 100 percent at all sampling points while zinc and lead were not detected throughout the sampling period. Cadmium showed low reduction rate ranging from 0 to 11.7 percent, while the rate of Copper reduction ranged from 0 to25 percent in January and February 2016. Zinc, lead and cadmium were generally not detected in the sludge samples except in January and February which could be due to the prevailing atmospheric conditions during the sampling period. Cu and Fe were detected through the sampling months of the study. We conclude that these municipal sewage plants are sources of pollution to their receiving watersheds and threats to public and environmental health.

- Description: South Africa and other African countries are faced with high levels of food insecurity and poverty levels as a result of slow growth of the macro economy and weak or sluggish rural development. Irrigation scheme development is seen as an important strategy to address the challenges faced by households in rural areas and restores growth and enhanced livelihoods. While the international experience shows that Irrigation schemes are potentially transformative of poor communities and have been operational for many years now, there is no marked improvement in living conditions of rural households in terms of livelihoods and income. This raises the question as to whether or not the schemes are viable from a socio-economic perspective and whether or not there are reasons for concern and revision of the policy framework for smallholder irrigation schemes. As a result of that, the broad objective of the study was to evaluate the contribution of smallholder irrigation schemes to household income and food security of rural households in Idutywa village of the Eastern Cape Province in South Africa. Specifically, this research investigated the major factors that influence their performance, impact of irrigation farming on rural livelihood and household food security as well as identifying the possible opportunities of production that would improve their performance. The study was carried out in Idutywa villages of the Eastern Cape Province in South Africa and employed survey data obtained from 107 households. The study employed a cross-sectional research design and the study employed stratified random sampling. The study made use of descriptive and inferential statistics to estimate the central tendency and dispersion as well as testing the hypothesis that there is a difference in the contribution between irrigators and non-irrigators using STATA and SPSS. Probit regression model was used to estimate factors that influenced the performance of smallholder irrigation schemes. The descriptive statistics employed included means, percentages and frequencies on the socio-economic characteristics of households in the study areas. The results show that females were dominant with a representation of 66.7 percent. The majority of households were aged and the mean age was 65 years. High level of illiteracy in the project area was revealed by the data. The average number of years, households spent in school was between 6 years to 10 years in school. Farming was found to be the major agricultural economic activity. Sixty-three (63 percent) were full time farmers. The results further show that household size ranges between 1 to 5 persons. The households were shown to be mostly dependent on social grant with household income hovering around R 1 000. The results from propensity score matching revealed that irrigation exerts a positive impact on household income. This provides sufficient evidence that irrigation schemes do make a contribution to rural livelihoods through their effect on household income and food security. This implies that government should continue investing in irrigation schemes as part of a strategy to grow the rural economy and improve rural livelihoods. This is in line with the Agricultural Policy Action Plan (APAP) and National Development Plan (NDP) of South Africa. Probit analysis suggests that age of the households, household size and market were some of the key determinants that positively influenced households’ decision to participate in smallholder irrigation schemes while access to credit had significant but negative effect on households’ decision to participate in smallholder irrigation schemes. Based on the findings highlighted above, it is recommended that addressing such barriers may create enabling conditions that would encourage households to access and participate more effectively in smallholder irrigation schemes.

- Description: Despite the vast research in science teacher preparation world-wide, little is known about secondary school science teacher preparation practices in Zimbabwe. The overall image that emerges from literature is that of challenges such as lack of programme coherence, policy inconsistence, poor funding for reform-based science teaching programmes, limited knowledge on issues critical to science teaching and learning, and mediocre performance of science teacher education graduates. Such challenges demand an examination of science teacher educator practices in order to identify relevant science teaching knowledge and skills the educators possess, an establishment of how their practices match standards and expectations in science teacher preparation, and an assessment of dimensions of the science teaching theory-practice gap. This study examined teacher education practices in the preparation of science teachers in two teachers’ colleges in Zimbabwe. The study is anchored in Miller, Ohana and Hanely’s (2013) framework for science teacher preparation called the Model of Research-Based Education for Teachers (MORE for Teachers). An exploratory sequential mixed methods design, within the post-positivist paradigm, was used to guide the collection of quantitative and qualitative data. Eighteen (18) Science teacher educators and 106 Science student teachers were selected from two Teachers’ Colleges through purposive sampling. A questionnaire was used to collect quantitative data while interviews, group discussions and documents were used to generate qualitative data. Qualitative data were used to buttress and expand quantitative findings. The major findings from the study were that, despite their limited research activity, teacher educators were well grounded in content knowledge in their various areas of specialisation. Although some standards and guidelines from syllabi, schools and the University of Zimbabwe, Department of Teacher Education (UZ-DTE) requirements on science teaching were followed, the teacher educators were not very clear about the extent to which reform-based science teaching guidelines influenced their work. Other findings revealed that the science teacher educators did a lot to prepare student teachers for Attachment Teaching Practice but did less when the trainees were eventually in the actual practice. It was also observed that science teacher education occurred with in a context where funding for teaching and learning was a challenge. The study’s major recommendation is the need for identifying preparation approaches that adequately equip science teacher educators with the relevant knowledge, skills and core practices that assist the development of coherent programmes.

- Description: Hostile school environments are a cause of concern and a perennial international educational problem. The UNICEF’s Child-Friendly Schools (CFS) approach is an international intervention meant to safeguard learners against hostile school environments. The CFS approach mandates schools to offer learners environments and conditions that uphold children’s rights and enhance their development to full potential. The purpose of this mixed methods research study, employing a concurrent triangulation design, was to explore the role of teachers in the promotion of CFS environments. Holsti’s (1970) role theory formed the theoretical framework of this study. The research questions focused on teachers’ understanding of the CFS concept, support offered, strategies employed, challenges encountered, and the implications for teacher professional development. The data collection methods were questionnaires, in-depth interviews, and document analysis with school heads, teachers and learners in the seven government urban secondary schools in Mutare district of Manicaland province in Zimbabwe. Quantitative and qualitative data were independently analysed and merged at the interpretation stage through triangulation of results. Major findings reveal that teachers have poor understanding of the CFS concept, are offered moderate support, occasionally employ viable strategies, and are hindered by various factors in the process of promoting CFS environments. The study’s implications for teacher professional development are rooted in identifying sustainable approaches that adequately equip teachers with relevant information, skills and attitudes that ensure the promotion of CFS environments.

- Description: The study sought to test the applicability of the Hotelling rule in South Africa. In environmental economics, the Hotelling rule has come to be a pillar of the exhaustible resources framework and in addition to this, it has presented essential insights into the consumption and extraction of non-renewable resources. Hotelling sought to address one important question which had been unanswered regarding the depletion of exhaustible resources: How much of the natural resource in question should be consumed presently and how much of it should be stocked up for future generations? The focus was to find a solution for those involved in the exploitation of natural resources to choose between the current value of the natural resource if extracted and sold and the future increased value of the asset if left unexploited. According to the Hotelling rule, the extraction path in competitive market economies will, under certain circumstances, be socially optimal. An extraction path that is not socially optimal compromises the welfare of future generations. The welfare of South Africa’s present population and more especially in the future will be greatly determined by the stock of natural resources available and the quality of the environment. Currently, the production processes deplete natural resources. Concern with the supposed increasing scarcity of gold in South Africa, and the possibility of running out of gold, has become a source of concern. South Africa’s gold reserves (gold in the ground that can be extracted profitably) are becoming depleted at an alarming rate. Most reserves are already exhausted; and the costs involved in mining lower-grade ore, and deposits located very deep in the ground, are becoming excessive. In light of this, this study sought to test the applicability of the Hotelling rule in South Africa. In order to empirically test the Hotelling rule, the study was guided by previous literature that had sought to test it. In this regard, the study used both descriptive and inferential statistics. The study has three data analysis chapters. The first two presented and examined the time series properties of gold prices, gold production and gold consumption. The third data analysis chapter examined the relationship between gold price and interest rates. In the first two data analysis chapters, visual inspection, growth rates, variance ratio tests and advanced unit root tests were used to examine the time series properties of gold prices, gold production and gold consumption. Results showed that the behaviour of the gold price series and gold production series in South Africa have a behaviour that is socially optimal. This is in line with the Hotelling rule. The rule predicts exponentially increasing resource prices and this result in mineral resources following the path of the positive trend. The positive trend is prompted by the increasing price reflecting the increasing scarcity of the resource. However, consumption trends were seen to be violating the Hotelling rule. The Hotelling rule predicts that the price increases until it eventually reaches the choke price, where the quantity demanded decreases to zero. However, in contrast to this, results showed that the demand for gold has been increasing instead of decreasing. This is not in line with the Hotelling rule. Furthermore the relationship between interest rate and gold price was negative and this suggested that the price of gold was not rising at the rate of the interest rate. The results of the study suggested that gold production is not following a social optimally path. The study recommended that the government come up with measures that prolong the lifespan of the gold reserves. These included research and development to promote technological innovations in the mining sector. This may make it possible for firms to access lower-grade ores. The study also recommended that since the Hotelling rule partly applied in the gold sector, there is a need to adopt some other theoretical measures that can ensure that the proceeds from the gold taxes are used in the most effective way.

- Description: The study sought to test the applicability of the Hotelling rule in South Africa. In environmental economics, the Hotelling rule has come to be a pillar of the exhaustible resources framework and in addition to this, it has presented essential insights into the consumption and extraction of non-renewable resources. Hotelling sought to address one important question which had been unanswered regarding the depletion of exhaustible resources: How much of the natural resource in question should be consumed presently and how much of it should be stocked up for future generations? The focus was to find a solution for those involved in the exploitation of natural resources to choose between the current value of the natural resource if extracted and sold and the future increased value of the asset if left unexploited. According to the Hotelling rule, the extraction path in competitive market economies will, under certain circumstances, be socially optimal. An extraction path that is not socially optimal compromises the welfare of future generations. The welfare of South Africa’s present population and more especially in the future will be greatly determined by the stock of natural resources available and the quality of the environment. Currently, the production processes deplete natural resources. Concern with the supposed increasing scarcity of gold in South Africa, and the possibility of running out of gold, has become a source of concern. South Africa’s gold reserves (gold in the ground that can be extracted profitably) are becoming depleted at an alarming rate. Most reserves are already exhausted; and the costs involved in mining lower-grade ore, and deposits located very deep in the ground, are becoming excessive. In light of this, this study sought to test the applicability of the Hotelling rule in South Africa. In order to empirically test the Hotelling rule, the study was guided by previous literature that had sought to test it. In this regard, the study used both descriptive and inferential statistics. The study has three data analysis chapters. The first two presented and examined the time series properties of gold prices, gold production and gold consumption. The third data analysis chapter examined the relationship between gold price and interest rates. In the first two data analysis chapters, visual inspection, growth rates, variance ratio tests and advanced unit root tests were used to examine the time series properties of gold prices, gold production and gold consumption. Results showed that the behaviour of the gold price series and gold production series in South Africa have a behaviour that is socially optimal. This is in line with the Hotelling rule.

- Description: The aim of the study was to investigate the strategies utilised in exiting households from the Harmonised Social Cash Transfer in Zimbabwe and also the role of the social worker in facilitating and ensuring a smooth readjustment thereof. The study area was Goromonzi District, where the research sample and participants were drawn. The data were collected with semi-structured in-depth interviews and focus group discussions. It emerged in the study that besides the financial constraints and general challenges characterising social protection in Zimbabwe, there have been some significant improvements in the livelihoods of the beneficiaries. For example the beneficiary households increased their food consumption in terms of quantity and quality, reduction of poverty among other positive outcomes. The study however noted that despite having registered some positive outcomes on the beneficiaries, the programme was designed without a clear cut exit/graduation strategy. Upon being exited from the HSCT, beneficiaries are supposed either to be supported to maintain their livelihoods or to be graduated into other social protection programmes so that the shock of being exited is minimised. In addition to the above, the study found that, graduation of social protection is hardly possible for the nature of HSCT programme beneficiaries, therefore ‘programme exit’ is the only most realistic thing to talk about in the programme. The study makes a case for curving a role for social workers in managing exit for beneficiaries of social protection programmes and helping families with the readjustment process post cash transfers. Furthermore, this study recommends that programmes should be designed either as ‘graduation’ focused programs or with a clear plan and road map of how beneficiary or programme exit would be handled. This will not only help in planning for the end-phase but also for the nature and approach for programme implementation. In addition, the study recommends that during implementation of social transfer programs, particularly cash, it is of essence to link the cash benefits with livelihood and asset building interventions to ensure sustainability. Families need to be encouraged through ‘soft messaging’ or supported to structure either group or individual savings and or investments in assets and livestock that will help cushion them in the event of sudden programme discontinuation or when faced with shocks and hazards.

- Description: South Africa is faced by huge societal problem of poverty and unemployment, twenty one years after the dawn of democracy. These societal problems have been addressed by policy interventions such as Expanded Public Works Programme. The programme targets Youth, women and people with disabilities. However it appears that the mainstream of the programme the employment creation through infrastructure does not accommodate all the targets especially the disabled. The study sought to investigate the role played by EPWP in alleviating poverty in Nyandeni Municipality and to find out to what extent it really alleviate poverty. The study took a triangulated research paradigm which used both qualitative and quantitative research approaches to collect data from forty eight respondents, by way of in-depth interviews, focus group discussion and questionnaire survey. The study found out that, inter alia, poverty remains high in Nyandeni Local Municipality, there is rampant empowerment exclusion in the area, the wage rate paid to beneficiaries is too little to pull them out of poverty and the effects of poor exiting strategy are unbearable to beneficiaries as they find it hard to find other means of employment once they exit the programme. Some of the recommendations which the study made in line with improved mainstream empowerment security in relation to EPWP are that ,the government needs to improve the information dissemination about proposed interventions to alleviate poverty and that communities should partner with them to alert them about their needs and what best interventions could impact real change. The government should be mobile and take services to people and there should be consideration to review wage rate. The researcher is quite optimistic that the study will play a part in improving policy implementation.

- Description: This study examines the experiences and realities of unemployed youths in Keiskammahoek, in the Eastern Cape Province, South Africa. It looks at the challenges are that experienced by unemployed youths in Keiskammahoek, an area which already has high volume of unemployment. It also explores the factors that account for unemployment amongst the youths in this area. The study adopted a qualitative research approach and the data was collected through semi-structured interviews and observations. Purposive sampling was utilised to collect data from 22 participants who included the rural youths, professionals and decision-makers. The findings of this study reveal that the majority of youths are unskilled and are not easily absorbed in different sectors of the economy. This study recommends that the government needs to target and maximize programmes that are supported by social and economic policies for young people’s benefit in order to alleviate the youth unemployment challenges.
