- Description: Enterococcus species are integral members of the gastrointestinal microfloral of humans, animals, birds, as well as insects. Their presence in water and food has been greatly associated with faecal contamination. This study was aimed at evaluating the incidence of Enterococcus species in cow dung and environmental water sources in three commercial dairy farms. In addition, their antibiotic profiles were determined as well as resistance and virulence genes. Furthermore, the genetic relatedness of the isolates was determined by molecular typing method (RAPD PCR). Three hundred and thirty four water and faecal samples consisting of 117, 116 and 101 were collected from Seven Star Middle Drift and Fort Hare Dairy trusts respectively. Of the 334 samples collected, 289 were of faecal origin and 45 from water sources within the farms. All samples were screened for enterococci using culture base growth media and molecular methods targeting the tuf gene. Speciation was done using species-specific primers and the incidences of various species within the farms determined. Furthermore resistance to antibiotics and multidrug-resistant phenotypes were established using the disk diffusion method. Genes coding for virulence and resistance were also determined. From the samples collected, 313 (289 faecal and 24 water) presumptive enteroccocci were isolated, 305 of 313 (97.45 percent) were confirmed as Enterococcus of which 239 of 305 (78.38 percent) were identified as E. hirae, 15 of 305 (4.92 percent) as E. faecium, 12/305 (3.93 percent) as E. durans, 6 of 305 (1.97 percent) as E. faecalis and 33 of 305 (10.82 percent) were unidentified. Out of the five virulence genes that were targeted in the study only gelE (71.80 percent of 219/305) and ace (27.2 percent 83/305) were present in the isolates. Phenotypic resistance to antibiotics was observed is in all twelve antibiotics tested with multidrug resistance phenotypes detected in some enterococcal isolates most predominant in Seven Star and Middledrift dairy trust. Finally RAPD profiles of the isolates showed high relatedness between the strains from water and cow dung sources in all three commercial dairy farms suggesting possible contamination from cow dung to the water sources or vice versa.

- Description: The South African fast-food industry has experienced substantial recent growth. However, as consumers have incorporated more fast food into their daily diets, obesity has become a major problem. The aggressive marketing techniques of fast food firms coupled with the busy urban lifestyle have significant implications for dietary health habits. The study aimed at investigating consumers’ attitudes towards fast food and the relationship between fast food consumption and obesity. The field survey design of the study employed a mixed-methods approach involving the use of a semi-structured questionnaire. The study was limited to the Mdantsane Township located in the Eastern Cape Province of South Africa. A quota sample of 200 respondents (n = 200) was selected from which data were collected using a self-administered questionnaire. Descriptive results revealed that the participants had positive attitudes towards fast foods. Although they agreed that eating fast foods increased body weight, the participants mostly did not feel overweight or obese. The participants were well aware of the negative health implications of excessive fast food consumption. This knowledge generally did not deter their positive fast food attitudes, although participants expressed their desire for additional healthier fast food options in the market. Regression estimates further revealed that carbohydrate and starchy type of fast foods (𝑃 < 0.01), other sources of fast foods (𝑃 < 0.05), age group, physical appearance and meaty type of fast foods (𝑃 < 0.10) had significant influence on the frequency of fast food consumption. The results further revealed that physical appearance (𝑃 < 0.01), religion (𝑃 < 0.05), age group and supermarkets and source of fast foods (𝑃 < 0.1) had significant influence on respondents’ BMI scores. The study concludes that there exist socio-economic and institutional factors that have considerable bearing on consumers’ fast food consumption and BMI scores. The study advocates for public health policy making concerning awareness of the negative health consequences of fast food consumption targeting mostly young adult females who mainly purchase in franchises and supermarkets with a high meaty diet.

- Description: From Introduction: The pine emperor moth, Nudaurelia cytherea capensis Stoll is an insect which, during the larval stage, causes extensive defoliation of the pine tree, Pinus radiata in the Cape province. These insects are susceptible to a virus disease, which on occasions causes large scale mortality. Five nonoccluded viruses have been shown to infect the pine emperor moth, and of these, one found in the greatest concentration, Nudaurelia capensis β virus (NβV) has been characterised to the greatest extent. This virus has been shown to contain RNA, to be isometric with a diameter of 36 mm, and to have a molecular weight of 16 million. The virus occurs in all stages of the insect's development, and by fluorescent antibody staining has been shown to develop in the cytoplasm of the host's cells. There have in recent years been a number of reports describing nonoccluded RNA viruses which appear to be similar to NβV. These are the viruses isolated from the moths Gonometa podocarpi and Antheraea eucalypti, and the one from the citrus red mite, Panonychus citri. These viruses have not been as extensively characterised as NβV, so the extent of the similarity between them and NβV is not known. However it would appear as if their discovery collectively heralds the emergence of a distinct new grouping within the nonoccluded RNA viruses of insects. This work reports the isolation and further characterisation of N. capensis β virus, its protein and nucleic acid.

- Description: The focal point of this study is to examine the print and online media representations of Jacqueline Phooko,a woman who accused former Cosatu General Secretary Zwelinzima Vavi of rape. Data for this study was obtained from eight South African newspapers and their websites. The study investigates whether the articles under review, including commentary and discussion online, focused on the incident itself or on the political landscape of South Africa. A content analysis was used to examine the data revelaling that Phooko was underrepresented and that most articles focused on Vavi’s political career. The research will use a feminist perspective to show that Phooko was under-represented in the media, in comparison to Vavi and his supporters who gained greater coverage, specifically in a political context. The significance of the findings is that although there are some strides achieved to have more women voices in the media however women are still under-represented.

- Description: The education system in Namibia was shaped by the policies located within the framework of the apartheid ideology. Since it gained its independence in 1990, the government positioned education at the top of the national priorities. Thus, there has been a growing realisation of the importance of more democratic forms of leadership in the education system for the country to be able to cater for a democratic society. Amongst others, teachers became active creators and managers of the learning outcomes. In addition, teachers are regarded as agents of change and the driving force for productive teaching and learning. Literature describes how the management in schools has been redistributing authority and power so that a culture of teacher leadership in school communities can grow. More importantly, school improvement depends more on the active involvement of teacher leaders as it is realised that people in formal positions cannot do everything. In this line this study investigated the understanding of teachers and members of management of teacher leadership practice and it further identified the structural and cultural factors which enabled and inhibited this practice in a primary school. This study is a case study of a Primary school in a semi-urban area of Otjozondjupa Region, a central part of Namibia. This study was conducted in the interpretive paradigm and it is a qualitative case in nature, employing semi-structured interviews, observation and document analysis. Triangulation over the data revealed that respondents have an understanding of the concept and that all teachers are involved in leadership roles at school which are more strongly found in the classroom and through involvement with other teachers. Teacher leadership roles at the case study school also occur within the whole school with some limitations and also extend beyond the school. Grant’s (2008) model of teacher leadership was used to analyse the data. The study suggested some hindrances and supporting factors of teacher leadership. The findings suggested that teacher leadership is understood at the case study school and that they experienced factors that enabled and hindered this practice at different stages. Enabling factors included the school structure, further studies and workshops attended, while teacher leadership is impeded by teachers’ unwillingness to collaborate with others and the platoon system. The study recommends future large scale studies, including at secondary schools, so that a broader sense of teacher leadership may emerge.

- Description: This thesis investigates the current legislation and police protocols set in South Africa, specifically regarding their adequacy in protecting the country’s children from sexual abuse. It focuses on relevant legislative provisions and protocols, on sexual abuse of children and on an empirical study conducted amongst a variety of officials who represent the South African legislation at different levels. Trends, developments and problems are analysed and brought forward to raise an awareness on the severity of the issue of child sexual abuse. In addition, this thesis explores how the diversity within the community of Grahamstown, South Africa, should be considered to a higher degree in the legislation. There is a clear indication of a prevalent patriarchal hierarchy within the community which, in reality, makes women and children more vulnerable to sexual abuse. The methods used in this thesis involves purposive sampling, which led to one on one interviews between the researcher and participant. Thisthesis concludes with confirmation of the hypothesis whereby the South African legislation is not adequately protecting the rights of children in regards to sexual abuse. However, to fully adapt the legislation and make it as versatile and as effective the State hopes it to be, it is necessary to understand the society’s perception on women and children and to rectify it. As difficult as this may sound, it all begins with a strong and influential government.

- Description: This qualitative study focuses on business level strategy adopted by Twizza to compete in the bottom of the pyramid market in the Eastern Cape, South Africa. Twizza enjoyed huge success between the years 2010 - 2014 as a medium to large sized manufacturer of carbonated soft drinks in the Eastern Cape. In light of this, the current study seeks to answer the following: What business level strategy did top management at Twizza adopt to compete and grow in the BoP market in the Eastern Cape, South Africa? The study takes the form of a case study to explore and understand the patterns of decisions adopted by Twizza’s top management in competing at the bottom of the pyramid. As such, the main objective of the study was to identify the business level strategy adopted by Twizza which enabled their superior performance within the BoP market. The study adopts Porter`s typology to explore business level strategy. Stratified, purposive sampling was used to identify 4 top managers as participants in this study. A total of 7, semi-structured, interviews were used to collect critical incidents from top management of Twizza. This was the primary data used in this study. This type of data was combined with relevant information which was gathered via published press articles and on-line commentary. The study found that central to Twizza’s business strategy were four pillars, namely, strict control and management of manufacturing costs, product quality equal to that of market leaders, the ability of the organisation to manufacture its own raw materials and ability to ensure product availability to the market to the market. These findings reveal that Twizza employed a hybrid strategy, anchored by cost leadership. Thus, Twizza incorporated elements of differentiation and best value strategies to offer its customers affordable quality.

- Description: The tolerances to sea water, sodium chloride and sodium sulphate of various cichlid, cyprinid and anabantid species which occur naturally in or near the Eastern Province region of Southern Africa, were determined, and correlated with their distribution ranges. Of the nine freshwater species tested, only Tilapia mossambica is able to disperse through the sea and is therefore the only member of the secondary division (Myers 1937) present in this region. The remaining species are possibly all limited to the use of freshwater links for dispersal between river systems. Death of fish in sea water and in sodium chloride is chiefly due to loss of osmotic control, but in solutions of sodium sulphate a pronounced toxic effect is responsible for death. In all the solutions used, an inverse relation between survival time and concentration is present. No evidence of any cells specialised for salt excretion was found in the gills of fish exposed to various salt concentrations.

- Description: The transport sector is very important in facilitating trade and travel between and within nations. It is at the core of every country‟s economy. In order for transport to play this critical role, this research suggests that it is important for countries to invest in infrastructure. This study examined the impact of transport infrastructure investment on export growth in South Africa for the period of 1994 to 2017. The standard procedure in interpreting the long-run VECM results was applied. All the variables enter the long-run equation significantly, and the signs and magnitudes also appear reasonable. The long run results suggest that transport infrastructure investment have a positive effect on exports in South Africa. As indicated on the long-run equation, transport infrastructure investment is significant in specification; the positive coefficient of the variable in the regression suggests that an increase in investment in the transport infrastructure will lead to an increase in exports. A vector error correction model was estimated with exports, transport infrastructure investment, real effective exchange rate, world gross domestic product, export prices and consumer price index. The variance decompositions show that exports have a high level of inertia in the first year with most of the variations dependent on past export variations. In the second year, employment contributes significantly to variations in exports. Transport infrastructure investment makes very little contribution. Impulse responses show that a positive shock to infrastructure investments increases exports marginally. The results of the study have revealed a number of policy implications that affect transport infrastructure investment and exports. It is highly recommended that government should improve transport infrastructure for all modes of transport as this will lead to an increase in the level of exports in South Africa. Empirical evidence shows that transport infrastructure investment granger cause exports. Government expenditure in transport infrastructure has been considered s one of the means to enhance economic development and transport sector operates as the crucial engine of the economic growth in both developed and developing countries

- Description: The transport sector is very important in facilitating trade and travel between and within nations. It is at the core of every country‟s economy. In order for transport to play this critical role, this research suggests that it is important for countries to invest in infrastructure. This study examined the impact of transport infrastructure investment on export growth in South Africa for the period of 1994 to 2017. The standard procedure in interpreting the long-run VECM results was applied. All the variables enter the long-run equation significantly, and the signs and magnitudes also appear reasonable. The long run results suggest that transport infrastructure investment have a positive effect on exports in South Africa. As indicated on the long-run equation, transport infrastructure investment is significant in specification; the positive coefficient of the variable in the regression suggests that an increase in investment in the transport infrastructure will lead to an increase in exports. A vector error correction model was estimated with exports, transport infrastructure investment, real effective exchange rate, world gross domestic product, export prices and consumer price index. The variance decompositions show that exports have a high level of inertia in the first year with most of the variations dependent on past export variations. In the second year, employment contributes significantly to variations in exports. Transport infrastructure investment makes very little contribution. Impulse responses show that a positive shock to infrastructure investments increases exports marginally. The results of the study have revealed a number of policy implications that affect transport infrastructure investment and exports. It is highly recommended that government should improve transport infrastructure for all modes of transport as this will lead to an increase in the level of exports in South Africa. Empirical evidence shows that transport infrastructure investment granger cause exports. Government expenditure in transport infrastructure has been considered s one of the means to enhance economic development and transport sector operates as the crucial engine of the economic growth in both developed and developing countries

Galwey and various others) • Techniques of thermal analysis • Pyrotechnic delay systems (with support from AECI Explosives) • Thermal and photostability of drugs (with Prof B.D. Glass) and, secondly, it was the title of the very successful book co-authored by Drs Andrew Galwey, David Dollimore and me. A large part of my research has been involved in the writing and editing of books, so these are covered in a separate commentary, while commentary on the more than 100 papers to which I have contributed forms the main part of this compilation. It is hoped that the electronic format will enable ready access of to all aspects of my research, including electronic versions of the original papers. The reader will need a copy of Adobe Acrobat Reader to access these.

Paul and Barnabas in Lystra (Acts 14:8-20): the contextualization of the Gospel in a Graeco-Roman city

- Description: This thesis will investigate the extensive Graeco-Roman characteristics of the Lystra speech and in so doing convey some clarity in the otherwise widely differing opinions held about it. This will be achieved by showing that Lystra was a Hellenistic city of some importance with a varied population. It will be argued that the initial reaction of the Lystrians to the miraculous healing of the cripple is to be understood as representing typical Graeco-Roman notions. This will include Luke's use of a legend which not only adds local colouring to the narrative but also introduces Graeco-Roman themes such as the blurring of the distinction between humans and gods and the custom of sacrifice. This contextualization immediately portrays the Graeco-Roman nature of the Lystrians' behaviour and attitudes. In addition to these themes it will be argued that the Lystrians are shown to being reliant on secondary notions of God, which when exposed to the proclamation of the apostles will prove to be inadequate. It will also be argued that the speech of the apostles is structured in a typically Graeco-Roman rhetorical form, where the errors are first exposed before the truth is presented. In conjunction with this structure it will be argued that the philosophical concept of which Dibelius has shown to be clearly presupposed in the Areopagus speech, is not only present in the Lystra speech but forms the philosophical basis on which it is structured. This concept explains the insistence by the apostles that they are human and that God has no need of such worthless things as sacrifices. It also explains the presentation of God's activity in creation and providence as an antithesis to a god who is in need. The Graeco-Roman aspects are brought to a close with the discussion of idea that an awareness of God does not depend on secondary notions acquired from legends or customs but that the truth is grasped through a process of reflection on creation and providence. This is an important notion in the speech for it exposes the Lystrians as being in need of a reorientation of their beliefs in God, away from those which are secondary to those which are primary and compatible with the truth.

- Description: The focus of the study was to explore and describe reasons for poor professional behaviour among nursing students at a public nursing college in the Eastern Cape. The objectives of the study were to explore and describe the reasons for poor professional behaviour among nursing students and to describe strategies to improve poor professional behaviour. The study has significance for the college management, staff, nursing students, registered nurses and everyone involved in professional development of nursing students. The population for this study consisted of third-year nursing students following the four-year comprehensive basic course for registration leading to the Diploma in Nursing (General, Community & Psychiatry) and Midwifery at a public nursing college. The research questions were: What do you understand by professional behaviour? What are the reasons for poor professional behaviour among nursing students? What could be done to improve professionalism among college nursing students? A qualitative, explorative, descriptive and contextual design was used as a framework for the study. Permission to conduct the study was obtained from the University of Fort Hare ethics committee and other relevant authorities as indicated in the study. Ethical principles were maintained and informed consent obtained. Data collection was done using focus groups and an audiotape with a purposefully sampling of 30 third-year nursing students at the public college of nursing. Data were analysed using Tesch’s method of analysis for qualitative research. Three major themes emerged: students’ understanding of professional behaviour, reasons for poor professional behaviour and methods to improve poor professional behaviour. It was concluded that poor professional behaviour has an effect on professionalism and it should be addressed and corrected for protecting the professional image. Recommendations: Policies regarding inappropriate professional behaviour at the college should be in place and easily accessible to every staff member and nursing student. Department of Health should conduct reflective courses and seminars on professionalism and these should begin at the same time as the academic programme.

- Description: Special needs education has always provided special challenges to school administrators, policy makers and teachers. The world-wide move towards inclusive education as an alternative to exclusive education or casual mainstreaming has resulted in significant developments in Namibia in the past decade. Global educational reforms have focused on education for all as well as inclusive education and Namibia is signatory to several conventions and declarations in this regard. Research in this field has largely focused on the role of the inclusive teacher, and of course the special needs of the learners. Little or no attention has been paid to possible managerial and organisational challenges which accompany the move to inclusive education. This thesis seeks to critically investigate the managerial implications of inclusive education. The focal point of this research is to gain a clear understanding of the managerial implications in an inclusive school for learners with visual impairment, chiefly through an exploration of the experiences of management members of the inclusive process. The research is located within a qualitative research paradigm, which is subsumed by a phenomenological model. The data gathered through in-depth interviews include many anecdotal accounts that provide insight into the ways respondents reacted to experiences at the inclusive school. The main findings of the research are highlighted and discussed. Recommendations arising from a critical analysis of these main findings are presented.

- Description: The current trends in sustainable development (SO) were examined in this study, which brought about the realisation that SO has become a business imperative. Mining, which is a highly impacting industry, is faced with the dilemma of implementing the principles of SO despite the realisation that its activities are severely limited by· the finite nature of the resource it is capitalising on. This reality, however, does not detract from the non-negotiable requirement for the industry to meet the increasing pressures to act responsibly towards the environment and the community in which it operates. Gold Fields has stepped up to the plate and has already taken several steps to achieve this end. These include the adoption of SO in its Vision, Values and strategies and the development and implementation of a SO framework to ensure the integration of the principles of SO into the business. Furthermore, Gold Fields has also entered into voluntary activities that further cement the commitment the company has towards so. These other initiatives include, inter alia, its International Council on Mining and Metals membership, UN Global Compact participation, becoming a signatory to the cyanide code, IS014001, and so on. This study focussed on several indicator categories and the identification of a set of supporting sustainable development indicators (SOls) for each, which included environmental, social, economic, technological, and ethics, legal and corporate governance (not in order of priority). These indicators were assessed by a carefully selected group of respondents whose collective wisdom and expertise were used to identify and weight supporting SOls for each of the indicator categories. These supporting SOls were in turn used to develop a model that is able to assist in the business's decision making processes when capital investment is being considered . A water treatment project that is currently being considered by Gold Fields was utilised to demonstrate how the decision making model can be applied to two different scenarios. The result clearly and successfully demonstrated that by proactively taking environmental, economic, social, technological, and ethics, legal and corporate governance considerations into account, a gold mining company is able to increase the level of SO of a capital investment project.

- Description: Governments around the world want to deliver better education, better health care, better pensions and better transportation services. They know that impatient electorates want to see change, and fast. But, the funds required to meet such expectations are enormous, particularly in the many developed economies where populations are aging and the public sector's productivity has not kept pace with that of the private sector. The need to get value for money from governments at all levels is therefore under the spotlight as never before. However, cost-cutting programmes that seek savings of 1 to 3% per year will not be sufficient and, in some cases, may even weaken the quality of service (Bhatia & Drew, 2006). One of the key innovative means to improve productivity, and do more with less, is through the implementation of lean initiatives. The purpose of this study is to conduct an 'Assessment of the status of lean implementation at selected SARS (South African Revenue Service) branch offices'. Literature review was conducted to investigate the origins of lean and how the service industry tapped from this philosophy, which was initially developed for the manufacturing sector. The lean philosophy has now been widely adopted in various service industries, from government agencies such as the South African Revenue Service to financial institutions such as ABSA bank, including the healthcare industry. The findings of the research indicated that even though the organisation has made a strategic decision to implement lean, this has not been entirely successful as there is a lack of understanding of lean among managers and team leaders. There are some pockets of excellence though. The researcher recommends that a comprehensive road map be developed to guide the organisation into a sustainable lean implementation.

- Description: Development aid in most of the developing countries can sometimes compromise the principles of public service broadcasting (PSB). This may be true when reflected against the tension between donor financed programmes in Malawi and the mandate of Television Malawi (TVM). Although the donor intentions are noble, the strings attached to the funding are sometimes retrogressive to the role of PSBs. A case in point is how donors dictate terms on the HIV/Aids communication strategies at TVM. Producers receive money from donors with strings attached on how the money should be used and accounted for. If producers deviate they are sanctioned through withholding funding, shifting schedules and reducing the funding frequency. The donors also dictate who to interview on what subject, how to conduct capacity building. Some scholars have researched much on the impact of commercialisation of the media. This study is a departure from these traditional interferences; it interrogates the interest of philanthropy tendencies by international donors in the three chosen HIV/Aids programmes broadcast by TVM. The study investigates the extent of pressure exerted by donors on the producers of HIV/Aids programmes in Malawi. Thus, the study seeks to illicit specifics in the power relationship between the donor and the producer hence the study employs the political economy of development aid as applied to the public service broadcasting and communication for development. The study employed qualitative research methods and techniques (in-depth interviews, case study and document analysis). The study reveals how donor ideologies dominate the Aids messages-content output of the texts constructed. The study argues that cultural alienation of the Malawian audiences retards efforts of donors in combating HIV infection rate.

- Description: This study investigates the relationship between savings, investment and foreign capital in South Africa, with special focus on the application of the Feldstein-Horioka theory. South Africa is a country that is still faced with relatively low saving levels. Given the low savings experienced by the country, available literature has alluded that foreign capital has played a greater role as the major driver of private investment expenditure in South Africa. Based on this background, the study empirically investigates the relationship between savings, investment and foreign capital utilising the Autoregressive Distributed Lag Model estimation technique for the period 1965 to 2015. The empirical results revealed that there is a positive and significant relationship between savings and investment in South Africa. The empirical results also show that for the period 1995 to 2015, the different types of external financial flows utilized in the study and investment have a positive relationship. These results have been consistent with our apriori expectations and other prior studies. This suggests that, in the case of South Africa, apart from interest rates, there are other factors that determine investment. The positive relationship between investment and foreign capital flows suggest that policies which are aimed at attracting the different types of foreign financial flows should be implemented.

- Description: This study investigates the relationship between savings, investment and foreign capital in South Africa, with special focus on the application of the Feldstein-Horioka theory. South Africa is a country that is still faced with relatively low saving levels. Given the low savings experienced by the country, available literature has alluded that foreign capital has played a greater role as the major driver of private investment expenditure in South Africa. Based on this background, the study empirically investigates the relationship between savings, investment and foreign capital utilising the Autoregressive Distributed Lag Model estimation technique for the period 1965 to 2015. The empirical results revealed that there is a positive and significant relationship between savings and investment in South Africa. The empirical results also show that for the period 1995 to 2015, the different types of external financial flows utilized in the study and investment have a positive relationship. These results have been consistent with our apriori expectations and other prior studies. This suggests that, in the case of South Africa, apart from interest rates, there are other factors that determine investment. The positive relationship between investment and foreign capital flows suggest that policies which are aimed at attracting the different types of foreign financial flows should be implemented.

- Description: Access to renewable energy supplies is a critical foundation for sustainable development and poverty alleviation. Anaerobic biogas-digesters also referred to as bio-digesters, have been identified as one of the leading technologies with regards to assisting in improving energy access for remote rural areas that still remain dependent upon biomass usage. This thesis assesses the potential feasibility of bio-digesters for rural households in South Africa by focusing on the experiences of a remote and rural community in Eastern Cape. A standardised survey was used to capture household details and energy use patterns of households with 180 interviews being conducted. Field observations were also conducted on the five bio-digesters installed in the community over a three month period. Despite the predominance of electrification in the community, households were heavily reliant upon biomass in the form of fuelwood and cattle dung to supplement their energy needs. Households supplemented their energy usage with alternative energy sources such as LPG gas and paraffin, especially during periods when electricity was unavailable or deemed too expensive. Initial knowledge of bio-digester technology in the community was non-existent, however with the installation of bio-digesters within the targeted villages, social learning was observed. Despite low temperatures bio-digesters continued to function throughout the study period, though malfunctions did occur and gas production did not reach optimal levels. Primary challenges encountered were the lack of financial subsidies for wide-spread adoption; the limited technical capacity of the community to conduct repairs and minimal gas production due to a build-up of ligneous materials within the gas chamber of the bio-digesters. Bio-digesters were found to provide significant benefits for households and further studies into maximising their effectiveness for rural South African households are recommended.
