  • Description: The study empirically examined the relationship between financial development and energy consumption in South Africa for the period 1980 to 2018. To achieve this objective, the study employed an autoregressive distributed lag bounds technique and Granger causality tests. Financial development, industrialisation, and urbanisation displayed a positive and significant relationship with energy consumption, both in the short run and long run. Economic growth was positive but not significant in the shortrun and long-run. Granger causality test results displayed a unidirectional causality running from financial development and industrialisation to energy consumption. This is in favour of an alternative hypothesis, meaning there is a relationship between financial development and energy consumption in South Africa. This study recommends policies that will allow financial development to stimulate clean energy consumption while considering increases in electricity consumption. The South African government must introduce new financial policies to enhance the process of capitalisation and produce sound energy infrastructure and introduce investments in renewable energy sources to safeguard against carbon emissions. , Thesis (Masters) -- Faculty of Economics and Financial Sciences, 2021

  • Description: Background There is a significant unmet need for family planning in South Africa where long acting reversible contraceptives (LARC), including intrauterine contraceptive devices (IUCD) are underutilised. The situation is no different in the Amathole District in the Eastern Cape where high rates of unintended pregnancies continue to be a problem. The postpartum period presents a unique opportunity for providing effective contraception. It has been established that immediate post-placental insertion of a copper IUCD is a safe, effective method that has the potential to reduce unintended pregnancy rates. A Post placental intrauterine contraceptive device (PPIUCD) refers to an IUCD that is placed into the uterine fundus immediately after delivery of the placenta after caesarean or vaginal delivery. The understanding of women’s perceptions, beliefs and lived experiences of the PPIUCD in this community has the potential to improve uptake of this method. The aim of the study was to fully explore the phenomenon of postpartum intrauterine contraception as a means of family planning at Madwaleni District Hospital in the Amathole District within the Eastern Cape, South Africa. Methods A qualitative, phenomenological study design was used in gathering data through a combination of three focus group discussions and in-depth individual interviews with three different groups of peripartum women. Data was collected from perinatal women at three snapshots in time, namely prior to labour, during the postpartum admission and at 12 weeks postpartum with the aim to fully explore the phenomenon of post-placental IUCD use in the study population. III Results The data was analysed using the framework method and five themes were derived iteratively from the text. These themes included the perceptions of perinatal women towards a PPIUCD, the origins of these perceptions, the reasons why women would or would not choose the method for themselves and lastly, the experiences of those women who chose the method. The findings of this study showed that PPIUCD was a novel method in this community and that misinformation, largely driven by deficiencies in antenatal counselling, led to hesitancy to adopt the method. These deficiencies extended to those women who consented to a PPIUCD insertion at caesarean section who did not fully understand what they had consented to. Despite this, women were open to a more effective, convenient contraceptive and the overall experiences of those women who chose to use a PPIUCD was positive. Conclusions Post-placental IUCD insertion was a relatively new method in the study population. Deficiencies in antenatal contraceptive counselling created uncertainty and scepticism which in turn contributed to low uptake of the method among perinatal women. Despite this, there was a strong desire amongst perinatal women to access effective, convenient family planning and prevent future unwanted pregnancies. The overall experiences of women who did choose the method was positive. This suggested that with the right counselling and support, there would be an increase in uptake of PPIUCD in the population. Recommendations from this study include the need to explore healthcare workers perspectives on this topic, to further explore the lived experience of PPIUCD users over a longer period of time and to explore the effectiveness of various antenatal counselling strategies to equip women to make peripartum contraceptive choices. , Thesis (Masters) -- Faculty of Health Sciences, 2021

  • Description: This study was aimed at exploring the teaching and learning of Euclidean Geometry in five selected senior secondary schools in the O R Tambo Coastal District of the Eastern Cape, South Africa. The literature review was based on existing knowledge in the teaching and learning of Euclidean geometry. The study was built on analyzing the effective teaching strategies based on the teacher’s Pedagogical Content Knowledge (PCK) in Euclidean Geometry (EG). Shulman and Ma’s perspective on teachers’ competencies and knowledge of Mathematics was used as the theoretical framework of the study. A mixed-methods sequential explanatory design was adopted for the study. A purposive convenience sampling technique was used to select research sites and participants. The main instruments used were questionnaires, semi-structured interviews, classroom observation schedules, and document analysis. Quantitative data was analyzed descriptively utilizing tables and graphs. Qualitative data were analyzed using thematic data analysis. The various findings were interpreted through the literature and the theoretical framework. It was found that learners have a poor foundation in geometry and the methods teachers employed to teach Euclidean Geometry were inappropriate. Recommendations and suggestions were made. It is hoped that these recommendations would be noted by the appropriate stakeholders to ensure that improvement in the teaching and learning of Euclidean Geometry is achieved in our secondary schools to help matriculates’ obtain good marks in the final certification examination.

  • Description: This is a mixed method research study that aims to investigate the Geometry Proficiency of Grade 11 learners in rural senior secondary schools of Mount Frere in Alfred Nzo Education District, in the Eastern Cape, South Africa. The study is oriented in interpretive paradigm and utilizes both quantitative and qualitative methods. The study was conducted in 10 rural senior secondary schools that were selected using convenient sampling technique. The quantitative part employed a survey that consisted of 19 mathematics teachers and total of 162 Grade 11 learners. Out of 10 rural senior secondary schools, three were purposively selected with their three (3) classes, three (3) Mathematics teachers and three (3) Heads of Mathematics and Science Divisions for qualitative part. Questionnaires were administered to 19 Mathematics teachers and 162 learners. Three teachers in three different schools were observed as they taught Grade 11 learners Circle Geometry in their respective classes. Qualitative data through observations, interviews and document analysis were gathered. The study targeted to provide an in-depth understanding of the Geometry Proficiency of the learners in the sample. The quantitative data were analysed using IBM Statistical Package for Social Sciences (SPSS) Version 22. The study found the failure of teachers to instate teaching strategies appropriate for generating acceptable levels of Geometry Proficiency and a myriad of challenges that were experienced by learners. These included inadequate preparation by teachers, lack of learning and teaching support materials, the manner in which Geometry was taught, learners' problem solving skills, absenteeism, illiterate and impoverished parents, and failure to understand the utilitarian value of Geometry. The study recommends that Van Hiele’s levels of Geometric thought as well as the Van Hiele’s phases of learning be implemented in the schools particularly in rural schools. These should be integrated with appropriate teaching strategies and learner teaching support materials, particularly the ones that include practical investigations. , Thesis (D.Ed) -- Faculty of Education Sciences, 2020

  • Description: This study sought to evaluate factors affecting the quality of food provided by the school nutrition programme in Mthatha, OR Tambo Inland Education District. This was a qualitative study in the form of case study research design. Two (2) schools were conveniently selected and from these, 2 principals, 2 school nutrition coordinators, 4 food handlers and 10 learners were purposefully selected to form the sample. Thus, 18 participants were selected in total. Interviews were used to collect data. A review of literature demonstrated that the school nutrition programme was valuable and played an important role towards addressing some of challenges prevalent in South Africa due to the history of the country. The literature reviewed also highlighted challenges faced by the school nutrition programme despite its tremendous success. These are some of the findings: the school nutrition programme was successful towards improving learner punctuality and engaging in the classroom. This had the potential to improve learner health overall; however, it was observed that lack of training around food preparation and hygiene could reduce the effectiveness of the programme. The provision for appropriate storage facilities was also noted as an issue that placed the programme at risk. These are some of the recommendations: the government should provide appropriate training and proper storage facilities in schools with nutrition programme; this could contribute meaningfully towards improving the quality of food provided by the school nutrition programme. , Thesis (M.Ed) -- Faculty of Education Sciences, 2020

  • Description: In 2002, the requisite number of ratifications to the Rome Statute was met, the International Criminal Court (ICC) was subsequently born. Just 16 years into its existence, the court finds itself under threat from the sovereign countries that at one stage, expressed their desire to improve the fight against impunity through a permanent international criminal court. But what has caused this shift? The ICC has been criticised for being a pro-African prosecution forum, this inference is drawn from the demographical distribution of the cases before the ICC that puts a significant majority of cases in Africa whereas other possible jurisdictions with similar cases have been left untouched by the ICC until recently. This study seeks to provide an analysis of the relationship between African states and the ICC. The study will provide a historical perspective on the development of International Criminal Law leading to the establishment of the International Criminal Court. This is followed by an analysis of the relations of the ICC and African states through three case studies of Kenya, South Africa and Sudan. The study will go further to provide an analysis of challenges that the ICC has faced with dealing with cases before and finally seek to explore the possibility of an alternative forum to prosecute perpetrators of international crimes centred in the African continent. , Thesis (MA) -- Faculty of Humanities, Social Sciences and Law, 2020

  • Description: This study aimed at investigating causes of orthographic errors in English Second Language essay writing with WhatsApp among High School learners in Mthatha, Oliver Reginald Tambo Inland Education District. The study was conducted among Grade 10 learners in three high schools. The study used a mixed research method with an interpretive paradigm to explore learners’ orthographic errors. A descriptive research design approach was adopted. The study sample consisted of 180 Grade 10 learners, as participants who were purposely selected from three high schools that offer English Second Language and use it as a language of learning and teaching. Data was collected using narrative essays written by Grade 10 learners after a pilot study was carried out on Grade 10 participants of this study. The written EL2 essays were carefully analysed for WhatsApp orthographic errors, and a few pictures of the essays were taken as examples of the depicted orthographic errors. A questionnaire was also used to find out commonly used social media platforms. Data were analysed manually and presented by the use of frequency tables and graphs. Besides, learners’ responses were categorised into themes. Findings revealed that WhatsApp word cut (WN), grammar errors (GR), word omission (WO), and shortened words, numerals in place of words were used by learners. Another finding was a direct translation (DHE) from mother tongue and words with multiple meanings and formal word meanings with multiple errors. Some of the recommendations resulting from the findings were that WhatsApp language be formally taught, a LEE SINCUBA WhatsApp model was proposed to help share the future of EL2 essays written with less orthographic errors, and a side-by-side LEE WhatsApp DICTIONARY was also proposed. , Thesis (D.Ed) -- Faculty of Education Sciences, 2020

  • Description: The interventional life writings of second generation life writers (young, black, middleclass South Africans) in post-apartheid South Africa have not attracted much academic debate in spite of the burgeoning of such writings recently. The intersection of race, class and gender in post-apartheid South Africa remains a problem and a rich site of research, hence this research’s reading of four selected life writings by young, black, middle-class South Africans living in post-apartheid South Africa: Fred Khumalo’s Touch My Blood: The Early Years (2006), Malaika Wa Azania’s Memoires of a Born Free: Reflections on the Rainbow Nation (2014), Khaya Dlanga’s To Quote Myself (2015) and Tumi Morake’s And Then Mama Said… Words That Set My Life Alight (2018). Using the intersectional approach, the study explores the lives narrated by second generation South Africans, in a manner similar to the grand narratives because of their historical and social context. The study focalises life/self-writers who have experienced post-apartheid trauma of being racialized, gendered and classed in a democratic country. This is a shift from the staple analysis of lives of political struggle against apartheid, narrated by historical legends such as Nelson Mandela. The study then, by focusing on ‘small voices’ closes a critical gap created by over-attention paid to grand narratives in South African life writing. Self-narrations by young, black, middle-class South Africans emerge not only as a way of narrating history but also as a means of making history. Through the deployment of the intersectional approach (the interconnectedness of inequalities) to analyse the systems of oppression associated with democratic South Africa, the four selected interventional life writers reveal how their experiences and identities are an outcome of constantly renegotiating power relations. , Thesis (MA) -- Faculty of Humanities, Social Sciences and Law, 2020

  • Description: The aim of this study was to investigate perspectives on the effects of principals’ workloads on Grade 12 learners’ academic performance in selected schools in the Eastern Cape, South Africa. Principals play the role of administrators and expert overseers of legal, contractual and policy mandate initiatives in schools. Their job descriptions frequently sound overwhelming and have the indispensable role of handling and resolving large and diverse challenges. The study was informed by participatory leadership theory. In this study, a mixed methods approach was used to collect and analyse data. The sample size for the study was 214, comprised of teachers, principals and School Governing Bodies for quantitative data. In addition, 13 participants (principals, School Governing Bodies and Circuit Managers) were used for qualitative data and, therefore, the total sample size for the whole study was 227 participants and respondents. Statistical descriptive, factor and inferential analysis were used to examine the quantitative data while in qualitative data, similar categories were identified and analysed manually. The findings revealed that principals’ added responsibilities, attending unplanned departmental meetings and lack of support from various stakeholders were the work drivers which increased the workload of the principal, thus, contributing to poor Grade 12 learner performances. These resulted to poor teacher supervision, which directly or indirectly led to a lack of effective teaching and poor learner performance at the matric level. This shows that there was no participation by everyone, and it can be argued that there was no participatory leadership. The study recommends, among others, that principals be adequately trained to cope with their workloads and in various other school managerial tasks. In addition, the DoE should design a schedule of meetings for all schools the previous year for the coming year, and not hold those meetings during school hours. Planning meetings in the previous year would limit and completely put to a stop the calling of unplanned departmental meetings. The study further suggests that more personnel should be employed to assist the principal in managing extra duties like school finances, school information systems, teacher unions, school nutrition, overcrowded classrooms, school discipline, school safety, teacher redeployment and teacher rationalisation. The study concludes by suggesting a proposed A. Nontso workload reduction model for the 21st century, which, if adopted would assist reducing principal’s workload. , Thesis (D.Ed) -- Faculty of Education Sciences, 2020

  • Description: Curriculum change processes in South Africa have been effected since 1994 after the general elections. This was meant to deconstruct the apartheid education curriculum, which was biased against the black majority. A curriculum change strategy is meant to improve the education system. It is also traditional that teachers form an important component of any curriculum change process. In spite of this, teachers have never played a centre stage in any curriculum change process. This study had the objective of investigating the impact of curriculum change on the academic performance of Grade 12 Business Studies learners in the Mthatha Education district of the Eastern Cape Province. The researcher set out to collect data using stratified random sampling design where a school represented a stratum. Two research instruments were constructed for this study. The two instruments were: a questionnaire and an interview schedule. The participants to the two research instruments were selected by random procedure. A random number table was used to select the participants based on a properly laid down statistical mechanism. Ten high schools constituting of 100 Business Studies learners and ten Business Studies teachers were randomly selected to participate. The data were analysed both quantitatively and qualitatively and later merged for common themes. The key findings were: curriculum change having influence on teachers’ and learners’ academic performance and improved availability of resources for teaching and learning. The findings also revealed factors that drive curriculum change and challenges facing curriculum change. Another key finding was the support by the majority of participants in favour of frequent curriculum reviews, an established positive attitude by teachers towards curriculum change and showing skills and sufficient knowledge in the cause of delivering of lessons. These were not influenced by the respondent’s age group. Finally, it was observed that there was dire need for frequent curriculum reviews and institution of learner-centeredness of classroom activities. The recommendations proffered included: Workshops for the professional development of teachers be on going, considering the inevitable continuous change. This should be boosted by incentives in the form of certificates or cash for workshop attendance. There should also be on-going post-training follow-ups and cluster visits by EDOs and Subject Advisors for guidance purposes: regular feedback helps teachers to effectively apply change because help is immediately available. , Thesis (D.Ed) -- Faculty of Education Sciences, 2019

  • Description: The purpose of this study was to investigate parents’ and teachers’ perspectives towards the teaching and learning of intellectually impaired learners at Foundation Phase in Mthatha Education Sub-District. This study explored the lived experiences of parents and teachers of intellectually impaired learners in this special school. It determined parents’ and teachers’ understanding of intellectual disability, the challenges they face in working with such children and strategies they use to deal with intellectually challenged learners. The research was limited to one special school in Mthatha, which is the only special school in this sub-district. The study used the qualitative research approach in the form of case study research design. The sample consisted of twelve participants, four parents of learners who are intellectually impaired and eight Foundation Phase teachers in this special school. These are some of the findings: The Education White Paper 6 on building an inclusive education and training is effective even though it is moving slowly. There has been no preparation on how it should be implemented in terms of human and other resources, knowledge and skills on special needs education. The challenges teachers face in teaching learners who are intellectually impaired include: learner-teacher ratio that is not followed, hence overcrowded classes; classroom management; lack of learner support materials; no special curriculum designed for intellectually impaired learners; confining subject matter and teachers not participating in skills development. The mechanism that were suggested to assist learners who are intellectually impaired included: equipping teachers with skills necessary for learning and teaching of intellectually impaired learners, establishing institutional level support teams, making more learning and teaching resources available, providing qualified human resources, mobilizing public support, government understanding impairment and therapists being employed (psychologists, physicians, nurses, doctors and social workers). Some of the recommendations are: conducting workshops on effective coping strategies for teachers, public awareness campaigns in communities about intellectual disability, school governing bodies working with the government to supply the school with adequate learner support materials, proper infrastructure, School Based Support Teams support service, the District taking responsibility for establishing networks that promote effective communication between learners, teachers and parents as well as with non-governmental organizations and welfare, health and justice departments and Supporting teachers on site. , Thesis (M.Ed) -- Faculty of Education Sciences, 2019

  • Description: The aim of this study was to establish the influence of using GeoGebra as a manipulative tool in providing processes of Grade 11 circle geometry at one school in OR Tambo Inland. The study adopted a quantitative approach and utilised the quasi-experimental research design. The sample consisted of 107 Grade 11 mathematics learners. Sixty (60) learners were in the experimental group and 47 in the control group. Pre-test and post-test, and likert-scaled questionnaires were used as instruments. Reliability and validity were ensured through test-retest, as well as member checking and a pilot study. All ethical requirements were followed. Findings revealed that pre-test results did not show much difference in the performance of experimental and control groups. After using GeoGebra, it statistically emerged that control group respondents performed lower than the experimental group. Findings obtained from the questionnaire also showed similar patterns. The study also found that participants who learnt circle geometry using GeoGebra were significantly motivated and that GeoGebra allowed learners to be exceedingly creative and discover skills of solving geometry problems by themselves. The positive impact of using GeoGebra resulted in significant differences on academic performance. Based on gender, more females compared to males agreed that GeoGebra was an effective manipulative tool in learning circle geometry. Interestingly, boys performed better than girls in the post-test. The study concluded that students who used GeoGebra showed higher ability in conceptual knowledge compared to students who used conventional methods. It also concluded that GeoGebra had positive effects on learners’ understanding as learners became significantly active and responsible for their own learning process as the software allows a self-learning process. Recommendations included the need for teachers to use the latest technology and to vary their methods of teaching to motivate learners. There is also a need for a workable alternative opposed to the rigid axiomatic approaches to circle geometry to facilitate and enhance learners’ ability to make and test conjectures. Curriculum planners and subject specialists need to emphasise on education systems that shift teaching and learning away from the traditional methods and emphasise on learning rules for manipulating geometry problems. , Thesis (M.Ed) -- Faculty of Education Sciences, 2020

  • Description: This study investigated the impact of energy consumption on the profitability and renewable energy preference among SMEs in the King Sabata Dalindyebo (KSD) local municipality. Cross sectional data was collected using a questionnaire and the adoption of information acceleration (IA) technique. The theoretical framework applied in this study is the theory of consumer-fuel-energy choice which is based on the energy ladder model and the associated fuel switching. Short-run sensitivity analysis (SRA), cost-benefit analysis (CBA) and multinomial logit model (MNL) were employed to measure the profitability and switching behaviour of the firms. SRA showed that the average monthly profit/loss by all firm categories were positive indicating a profit in the consumption of non-renewable energy (NRE). In contrast, results showed that all categories of the firms’ ran at loss if they were to switch to the renewable energy (RE) immediately. Results for CBA indicate that only RE system option satisfied the economic viability of all the three CBA decision criteria on both discount rates, proving to be a viable investment choice for all firm categories. The MNL regression results showed that the number of rooms, firm revenue, irregular power experiences, product information, price, business age, firm grades, gender of the respondent, and the educational levels have a statistically significant impact on willingness to switching from substantial to full willingness.

  • Description: ABSTRACT This study sought to establish ways of dealing with stress as experienced by primary school teachers. Stress is a global phenomenon that affects everyone regardless of gender, resources and environment. Although this phenomenon is well researched, it remains a worrying challenge particularly to schools’ effectiveness. Teachers face many challenges in South African schools such as the ill-discipline of learners and overcrowding of schools. It is vital that schools come up with better intervention programs that can assist teachers to overcome stress. This study involved qualitative approach method and a case study design was used for sampling purposes in which five (5) post level 1 Mathematics teachers from different schools responded to interviews. Data were analysed using categories or themes. The findings of this study revealed that stressful experiences of primary school teachers were overcrowding, infrastructure, lack of parental involvement and lack of reliability in doing homework and extra-co-curriculum activities. It is recommended that the school disciplinary committees should be trained in various disciplinary measures that can be implemented in the school to curb learner ill-discipline and lack of commitment. It is also recommended that a working relationship should be built properly between the school and the Department of Basic Education, motivational speakers and educational counsellors should meet with all learners to motivate them to have high desire for and interest in education and to build their self-confidence in the classroom. Keywords: Stressor, anxiety, burnout, alarm, frustration, and strain

  • Description: The increase in use and production of engineered nanoparticles in recent years points towards their inevitable release into freshwater ecosystems. Subsequently, exposure to organisms in freshwater ecosystems is to be expected. The aim of this dissertation was to synthesize silver nanoparticles (AgNPs) using silver nitrate, gelatine and maltose as precursor, capping and reducing agent respectively. Cytotoxic effects of the as-synthesized AgNPs was evaluated at concentrations of 0.031 μg/L, 0.250 μg/L and 5.000 μg/L on selected target organs in zebrafish (Danio rerio ) after 96 hr of exposure, under a 24 hr static renewal system. Formation of AgNPs was investigated by UV-Vis spectrophotometry, which displayed absorption maxima peak characteristic of plasmon resonance band for silver at 419 nm. From transmission electron microscopy, AgNPs was found to be small, well dispersed and spherical in shape with a narrow size distribution, and an average particle size of3.76 ± 1.00 nm. Histopathological alterations following exposure to AgNPs was noticed in the gills, epidermis, muscle tissue and kidney. Secondary lamellae hypertrophy, oedema and epithelial lifting was observed in all experimental groups. Curling and clubbed tips of secondary lamellae were observed at the lowest concentration (0.031 μg/L). Hyperplasia and lamellae fusion was most common at the median concentration (0.250 μg/L) of AgNP exposure. Hypertrophy of endothelial cells along with blood vessel congestion was also observed. Reduced secondary lamellar length, lamellar erosion and thinning were observed at the highest concentration (5.000 μg/L).AgNP exposure also altered the shape of alarm cells. In addition, hyperplasia and hypertrophy of goblet cells were observed at the highest concentration (5.000 μg/L) at 96 hr. At 5.000 μg/L of AgNP, PAS reaction was intense (deep purple), while the number and size of these cells decreased. Staining with AB pH 2.5 demonstrated an intense deep purple staining at the lowest and at the median concentration (24 hr). Moderate staining was seen at the higher concentrations. Muscle bundles with severe oedema, their thickening and separation were more pronounced in all treated groups. Histopathological tubular deformation and mononuclear cell infiltration were observed in kidney tissues. In addition; an increase in melano‐macrophage aggregation intensity was identified on the 48 hr in the treated groups. An increase in tubular epithelial cell regeneration/ proliferation, resulting in production of new epithelial cells which was indicative of recovering of kidney tissues from AgNP induced injury at 96 hr of exposure. Results presented here shows that fish respond to the presence of AgNPs.

  • Description: Abstract The study investigated whether commercialisation of subsistence agriculture can reduce poverty in the King Sabatha Dalindyebo Local Municipality. The study also sought to identify the constraints that hinder subsistence farmers in the commercialization of their agricultural produce, measured the degree of commercialisation among small scale crop farmers and made recommendations that will facilitate increased commercialisation among small holder crop producers in the study area. A cross-sectional study was conducted in the King Sabatha Dalindyebo Local Municipality. A quantitative research method was used in the study. To achieve these objectives data were collected using a structured questionnaire. This was followed by data analysis using the Statistical Package for Social Sciences Software (SPSS). The study made use of the Household Commercialisation Index (HCI) to measure the level of commercialisation among the farmers in the study area. An Ordinary least squares regression (OLS) analysis on the determinants of commercialisation was also conducted. Poverty was measured using income generated by farmers from the sale of their produce and bench-marked with the food poverty line of South Africa in 2017 year prices as stipulated by STATSSA. A binary logistic regression analysis was conducted to measure poverty against independent variables. It emerged from the study that 74% percent of the farmers fall below the halfway mark of the commercialisation treshhold. The regression analysis showed that three variables were significant for commercialisation. These were farming experience, access to credit and other sources of income. The farming experience was the variable with the strongest significance level, and hence affects the Household Commercialisation Index (dependent variable). The only variable that was not significant is the plot size. The analysis of results for poverty reduction revealed that the Household Commercialisation Index (HCI), access to credit and educational level were significant for poverty reduction and hence are said to be the necessary economic variables that improved the welfare of farmers. The variables that were not Significant were the size of the plot, access to extension services, access to irrigation and savings. The study also revealed that the constraints that are faced by the farmers in the King Sabatha Dalindyebo (KSD) are inadequate extension facilities, poor road and irrigation infrastructure, lack of access to credit, unfenced ploughing field, poor storage facilities and lack of access to the market. The recommendations of the research study were that there is a need for the government, both at a local and national level to intervene Walter Sisulu University ii by providing the necessary support to improve the welfare of the farmers in the region. It is further suggested that extension services should be improved to enhance agricultural skills and increase productivity.

  • Description: Citrus limon commonly known as lemon is the third most cultivated citrus genus in South Africa mainly cultivated for its juice. This study aims at analysing the chemical composition of Citrus limon waste (leaf and peel) and evaluation of their insecticidal properties. Leaves and peels of Eureka lemons were collected from three South African citrus farms (Addo, Riverside and Mystic), while Lisbon lemons were only collected from two citrus farms (Addo and Riverside) in 2017 and 2018. A total of 36 essential oils were extracted using the Clevenger like apparatus. Analyses of these oils were done using GCMS. An infusion extract of C. limon was prepared according to the standard method and subjected for phytochemical screening to detect and quantify secondary metabolites present. D-Limonene was the major compound identified in all the 36 oils from Eureka and Lisbon peels and leaves (27.9-74.8%). Other dominant compounds identified in Eureka leaf and peel oils were -pinene (5.8-13.2%), -terpinene (4.8-6.7%), geranial (4.0-15.4%), z-citral (6.7-11.7%), sabinene (4.5-6.3%), nerol (4.0-5.4%) and neryl acetate (6.3-9.5%). Some compounds were however present only in some oil such caryophyllene (6.5%) in Mystic dry leaf oil, geraniol (8.0%) in Addo dry leaf oil, as significant compounds. Lisbon leaf and peel essential oils -pinene (4.4- 11.8%), p-cymene (4.2-6.3%), -terpinene (4.4-6.9%), geranial (8.6-17.3%), z-citral (7.1-13.6%), neryl acetate (4.7-9.1%) (5.4-5.9%) were the other prominent peaks identified in the oils. These C. limon essential oils were further tested for insecticidal activities against maize weevils by conducting repellent assay, fumigant assay and contact toxicity; also plant viii powder was used against maize weevils. In general, for all the bioassay, mortality of the insect increased as the contact days with the oil increased. Contact toxicity assays of C. limon peel essential oils were most effective against S. zeamais in which all weevils were dead by day 3 (100% mortality) at 300 μL, while at other concentrations (50, 100, 200 μL) over 50% mortality was observed. The fumigant potential was high with the peel oil with over 50% mortality at 32 and 40 μL in day 4. The oil had moderate repellent effect on the maize weevil. Riverside Eureka dried powder peel was the most effect in all. These results unveil the medicinal potential of South African citrus waste in post-harvest crop protection and good sources of some chemical compounds which are of medicinal value. Furthermore, this study also reveals the economic potential of these wastes in job creation.
