- Description: Four low symmetric A2B meso-substituted Cu(III)corroles with electron withdrawing meso-aryl rings have been synthesized and characterized. A detailed analysis of the optical and redox properties has been carried out by comparing their optical spectroscopy, electrochemistry and spectroelectrochemistry to a series of DFT and TD-DFT calculations. A series of experiments demonstrate that these Cu(III)corroles can be used as highly effective catalysts for hydrogen evolution reactions (HERs). Moreover, when the number of fluorine atoms at B meso-position is increased, there is a marked enhancement in the catalytic ability of the corrole complexes, which demonstrates that modification to the structures of low symmetry corroles is a useful strategy for developing new HER catalysts.

- Description: The potential for restocking depleted natural reefs with hatchery abalone, Haliotis midae, to support a commercial ranching venture in the Eastern Cape Province of South Africa was investigated. A baseline stock assessment and analysis of historical fishery data provided compelling evidence of significant declines in the abalone stock, attributed to uncontrolled illegal fishing over the last 20 years at the study site. A ranching pilot study was undertaken where small-scale replicated seeding experiments were set up which quantified the effect of seed size, density and habitat on survival and growth of hatchery-reared abalone. Thirty-six experimental plots were seeded with 8400 abalone spread evenly over two broad habitats. Mean retrievals of seeded abalone were 17% ranging from 4 - 42% after a minimum of eight months at large. Release density and large-scale habitat had no significant effect on seed survival, but smaller seed size (40.0 ±3.7mm shell length) achieved higher (F1, 22 = 4.64, p = 0.042) retrievals than larger seed size (53 ±3.7mm). Growth rates were an average of 30% higher in the shallow sites compared deeper sites (t1, 1091 = -2.79, p = 0.005). There was seasonal component in growth with a 0.55 ± 0.04 mm per month higher rate in summer than during winter (t1, 1091 = -12.45, p < 0.001). Abalone seed releases were also conducted on a larger scale, which focused on the economic potential for commercial-scale ranching. Over 160 sites were seeded with 1.4 million hatchery reared abalone or 30 metric tonnes. Seventeen sites underwent long-term monitoring of survival with repeated sampling events on sites over a period of up to 666 days. Nine of these sites were seeded with 140800 small abalone (29 – 40 mm), three sites with 25100 medium abalone (30 – 46 mm) and five sites with 14700 large abalone (60 – 84 mm). There was a significant difference in survival between the seed sizes (F4,6329 = 304.3, P < 0.001). The Generalized Linear Mixed Model (GLMM) calculation estimated the instantaneous apparent mortality rate for small, medium and large abalone at 1.19 yr-1 , -0.9 yr-1 and -0.67 yr-1 , which equated to a survival rate of 21%, 28% and 36% per year respectively. The weighted mortality rate calculated according to the seed size differential mortality and the number of seed released for those sizes was 1 yr-1 or 25% survival. In conjunction with a conservative somatic growth rate of 1.2mm.m-1 and plausible emigration rates, a range of biomass harvesting estimates were obtained. Movement and mortality were investigated using video analysis which showed that hatchery seed had the ability to move considerably once released onto natural reefs and confirmed that mortality immediately following releases was due to the heavy predation pressure as confirmed by shell collections. This project has demonstrated that potential exists for ranching in South Africa and highlights critical factors that need to be addressed if ranching is to be an economically viable operation.

- Description: Publisher version , From Introduction: The subject of abortion is both timely and of high relevance to feminists. In the past few months, women’s access to abortion has been contested in various parts of the world. In many countries in Latin America, the Zika outbreak raised the demand for abortions among pregnant women who had contracted (or feared contracting) the virus, with its risk of severe foetal abnormalities. In Poland, mass demonstrations by women succeeded in turning back proposed legislation prohibiting abortions. The outcome of the U.S. elections in late 2016 raised grave concerns about the future of American women’s access to abortion, which was already limited by stringent regulations and funding restrictions. We chose the title ‘‘Abortion in Context’’ to signal that we sought to publish work that moved beyond examining abortion as a ‘‘stress experience’’ encountered by individual women or as a possible precursor of mental illness. Our goal was to assemble a set of articles that would prompt readers to think critically about practices and discourses surrounding abortion. We further hoped to include work that would address the meanings and practices of abortion in the global South and among minoritized groups in the global North. We were pleased by the enthusiastic response to our Call for Papers. We note that Eklund and Purewal (2017, this issue) address abortion in China and India. Thoradeniya’s (2017, this issue) review of Abortion in Asia (Whittaker, 2010) provides a glimpse of the complex and varied practices, policies, and experiences of abortion in parts of South and Southeast Asia. Chiweshe, Mavuso, and Macleod (whose work will appear in Part 2 of the Special Issue) take up abortion in South Africa and Zimbabwe. Le Grice and Braun (whose work will also appear in Part 2), examine Maori perspectives on abortion. In this Part 1 of the Special Issue, we present work that locates abortion practices and policies in legal, social, and healthcare contexts. Women’s efforts to exercise agency with regard to bodily integrity in the context of pregnancy are shaped most obviously by the legal regulations in the jurisdictions where they live, but they are also shaped by social and cultural issues, biotechnological advances, and healthcare systems. The articles offer detailed examinations of some of these complex contextual framings of abortion.

- Description: In southern Mozambique, the sap and leaves of the palms Hyphaene coriacea and Phoenix reclinata are harvested by local people as sources of traditional beverages, weaving, roofing, fencing and furniture material. The harvesting of these palm products may affect palm population structure, dynamics and viability. This work evaluates the abundance, population structure and harvesting selection of these two heavily harvested palm species. Hyphaene coriacea was more abundant, with a mean density of 601.5 ± 455.9 stems ha−1 against the 251.9 ± 527.3 stems ha−1 of Phoenix reclinata. Both species exhibited steeper negative slopes in the regression analyses of the size class distribution, indicating the presence of more individuals in smaller size classes. Although there was a dominance of shorter over taller size classes, limited recruitment was observed through low densities of seedling and juvenile size classes compared to the size class 1–50 cm. The Simpson index of dominance, the permutation index, and the fluctuating quotients between the consecutive size classes showed a degree of instability in both populations. Hyphaene coriacea appears to be more resilient to tapping than Phoenix reclinata, evident in the higher rate of stem survival after tapping. Hyphaene coriacea is favored for tapping compared to Phoenix reclinata. Tappers exhibited positive selection for five out of the six Hyphaene coriacea size classes, against only one Phoenix reclinata size class. The most preferred size class to tap for both species was between 101 cm and 150 cm tall. The instability detected by the indices of population stability, the coincidence between the size classes with high numbers of dead stems and the most preferred and the low level of the sexual reproduction encountered in both population emphasizes the need for long-term monitoring as well as management measures that integrate the resource users, to ensure the long-term sustainability of these populations.

- Description: This study involved evaluating the extent to which universal access to quality grade R was realised by 2012 in Cofimvaba education district in the Eastern Cape Province. The evaluation was done through the implementation of goal 11 of the Education Sector Strategy - the Action Plan to 2014, revised to 2019. It further sought to find out whether universal access to grade R occurred to all learners who registered for grade 1 and whether the quality of grade R had improved between 2010 and 2012 in Cofimvaba education district. Improving the quality of grade R in this study included an assessment of the level of qualification of grade R practitioners and an improvement of the quality of grade R tuition through the use of textbooks, workbooks and resource packs supplied to grade R by the Department of Basic Education (DBE). The study used both the qualitative and quantitative methods. Questionnaires were used as data collection methods from grade R practitioners and grade 1 teachers. The respondents in this study consisted of twelve grade R practitioners, ten grade 1 teachers and two officials from Cofimvaba district office. The findings of this study revealed that the universal access to grade R, calculated from grade 1 learners who received formal grade R, was not achieved over the three-year period 2010-2012; albeit the target of grade 1 learners who should have received formal grade R by 2012 was a mere 50 percent. The percentage of grade R learners who received access to the required textbooks fell below the expected target of 100 percent. Although 77.61 percent does not signify bad performance, the non-attainment of 100 percent access to the required textbooks could not be acceptable because the absence of textbooks meant that effective teaching and learning could not have taken place. However, these findings uncovered that the supplied textbooks and workbooks were high quality learning and teaching materials. The findings also uncovered that the ECD-grade R practitioners, at the time, had the necessary work experience and limited qualifications as a means to teach the grade R classes. A pressing matter for the Department was the improvement of conditions of service for practitioners; their professionalisation as well as further improvement of their qualifications. It was revealed, through this study, that there was a slight improvement in the universal access to grade R; however, the quality of grade R still needed attention especially in so far as the provision of suitably qualified practitioners is concerned.

- Description: This study involved evaluating the extent to which universal access to quality grade R was realised by 2012 in Cofimvaba education district in the Eastern Cape Province. The evaluation was done through the implementation of goal 11 of the Education Sector Strategy - the Action Plan to 2014, revised to 2019. It further sought to find out whether universal access to grade R occurred to all learners who registered for grade 1 and whether the quality of grade R had improved between 2010 and 2012 in Cofimvaba education district. Improving the quality of grade R in this study included an assessment of the level of qualification of grade R practitioners and an improvement of the quality of grade R tuition through the use of textbooks, workbooks and resource packs supplied to grade R by the Department of Basic Education (DBE). The study used both the qualitative and quantitative methods. Questionnaires were used as data collection methods from grade R practitioners and grade 1 teachers. The respondents in this study consisted of twelve grade R practitioners, ten grade 1 teachers and two officials from Cofimvaba district office. The findings of this study revealed that the universal access to grade R, calculated from grade 1 learners who received formal grade R, was not achieved over the three-year period 2010-2012; albeit the target of grade 1 learners who should have received formal grade R by 2012 was a mere 50 percent.

- Description: The Council of Australian Therapeutic Advisory Groups (CATAG) (2013) define a Pharmaceutical and Therapeutics Committee (PTC) as a ‘multi-disciplinary team committee with a commitment to the overall governance of the medicines management system in health service organizations to ensure the judicious, appropriate, safe, effective and cost-effective use of medicines’. The multi-disciplinary team includes the health care providers, who are actively participating in the health care systems, such as doctors, pharmacists, nurses, administrators, finance officers, quality improvement managers and other staff members who participate in the medicine use processes according to their knowledge and skills. The major role of this committee is to evaluate and promote rational drug use by health care providers and consumers. In addition, this committee is responsible for developing systems and strategies to prevent adverse medicine reactions and medication errors, enhance rational prescribing and dispensing, provide educational activities and ensure the use of quality and cost-effective medicines. This is a cross-sectional study that was aimed at exploring the structure, activities and functions of public sector institutional Pharmaceutical and Therapeutics Committees (PTC) in the Eastern Cape (EC) Province in South Africa (SA). The primary objectives of the study were to (i) investigate and describe the structure, functions and the activities of the institutional PTCs, and (ii) explore and describe the perception of PTC secretariats on the functionality of the institutional PTCs. A purpose-designed questionnaire including both quantitative and qualitative aspects adapted from other international studies was piloted prior to being used for data collection. The secretariats of the institutional PTCs were requested to complete the questionnaire. Data were analysed using descriptive statistics for the quantitative aspects and thematic analysis for the qualitative component of the questionnaire. Data collection commenced after approval by the relevant ethics committees had been granted. The findings of the study reflected that the majority of the PTCs in the EC province, SA are district/sub-district PTCs which are a cluster of a number of health care institutions in close proximity. The PTC members were appointed by the executive authority as recommended by the literature and other guiding documents. As expected the nurses were dominant as the members of the PTCs in these district/sub-district PTCs. The secretariats were the pharmacists where pharmacists were available and chairperson were doctors. These findings correspond to the recommendations by the National Department of Health PTC policy (2015) and the studies conducted in other countries. A number of PTCs had sub-committees formed e.g. ABC analysis review committee, medicine utilization evaluation (MUE) committee and pharmacovigilance committee to optimise their functionality. Out of 15 PTCs only five PTCs with sub-committees reported functions and interventions, establishment of policies and SOPs. The rest had no outcomes or interventions reported. Poor production of policies and SOPs was observed which differs from other countries’ PTCs. The focus of sub-committees in other countries is the development of formulary and policies related to medicine use. These findings pose a question regarding the functionality and effectiveness of the existing institutional PTCs in the province. In addition, the basic documents that are required to run the PTC were unavailable in a number of PTCs. Barriers to the functionality of PTCs were reported i) Lack of pharmacists and training in PTCs. ii) The rural nature of the EC province and iii) Unavailability of resources including lack of re-imbursement of personal costs. These findings reveal that budget allocation for institutional PTCs is crucial for their functionality. It can be concluded that in the EC province the institutional PTCs which are active and effective are low in number and do not cover all geographical areas. Secondly there is a need for training and educating the PTC members on the role of the PTC members, role of sub-committees, development of policies, SOPs and the basic documents for the functionality of the committee. It is also important that during training the monitoring and evaluation of the effectiveness of the committee is emphasised. Therefore, the choice of the PTC objectives should be measurable as they can assist as indicators of effectiveness. Support by the executive authority has been observed.

- Description: Research indicates that many children finish primary school in Southern Africa still reliant on inefficient counting strategies. This study extends the research of the South African Numeracy Chair project to early mathematics intervention with Grade 2 learners. It investigated the possible adaptation of the Mathematics Recovery programme to facilitate learner progression in early arithmetic strategies. This study aimed to investigate the possibility of adapting the Mathematics Recovery programme for use in a whole class setting, and to research the effectiveness of such an adapted programme. This study also aimed to investigate the extent of the phenomenon of unit counting and other early arithmetic strategies used in the early years in Zambia. This study was conducted from an emergent perspective. A review of the literature indicated that children who become stuck using unit counting face later mathematical difficulties, and that teacher over-emphasis on unit counting in the early years of schooling may be a contributing factor. This study used a qualitative design research methodology that consisted of a preparation phase, teaching experiment and retrospective analysis. The context of this teaching experiment was a seven week after-school intervention with a class of Grade 2 learners aged seven to eight in a rural Zambian primary school. Data collection and analysis focused on video recordings of a sample of 6 learners. The experimental teaching content focused on the Early Arithmetic Strategies aspect of the Mathematics Recovery programme. Although limited by time and research focus, this study found that all learners made some progress in early arithmetic strategies, and indicates that the Mathematics Recovery programme has potential for adaptation for early intervention in whole class teaching to address the mathematical education challenges in Zambia and beyond. This study also found that unit counting predominated in the sample learners, but that strategies were not yet entrenched, indicating this was a suitable age for early intervention. This study makes methodological contributions to a growing body of research into the adaptation of the Mathematics Recovery in Southern African contexts and suggests avenues for possible further research.

- Description: It is worth raising the question, why are wild edible plants (WEPs) which are rich in diverse nutrients and widely abundant underutilized despite the increasing rate of undernourishment in poor regions? One reason is that their culinary uses are not quantified and standardized in nutrition surveys, and therefore, they are not properly included in household diet intensification and diversification across regions and cultures. Active steps are needed to bridge this gap. This paper outlines the constraints to including WEPs in nutritional surveys as the lack of standard ways of food identification of diverse WEPs, lack of specific food categorization and therefore difficult dissemination across regions and cultures. As a way forward, a functional categorization of 11 subgroups for WEPs is introduced and discussed. In labeling these sub-food groups, the paper advocates that more WEPs food items and culinary uses should be enlisted during household nutrition surveys. Food researchers could then capitalize these enlisted species and disseminate them to promote diverse food use of WEPs in other regions where they exist but are not utilized as food.

- Description: Populations of small prey species (< 92 kg) can be regulated by competition, habitat-mediated responses, climate change, disease and predation. Populations of small prey species have declined in the Addo Elephant National Park Main Camp Section since the reintroduction of apex predators (lion and spotted hyaena). One possible explanation is predation by lion and spotted hyaena. However, small prey species are not generally considered preferred prey items of these predators, hence their contribution to predator diets needs to be explored. Global Positioning System (GPS) cluster analysis has emerged as a viable approach to locate lion kills for lion diet estimation in AENP, however this technique is known to bias diet estimates to large prey species. Understanding the impact of lion predation on populations of small prey in Main Camp therefore requires better estimates of lion diets. This study investigated the potential underestimation of small prey species in lion diet estimates by combining the data from scat analysis and carcasses located at GPS clusters. The adjusted lion diets were then used to investigate if the impact of lion predation could explain declines in small prey, by relating lion prey preferences to prey population trends in Nyathi. Using the results from Nyathi, it could then be inferred whether lions could have been responsible for the declines observed in Main Camp. Six GPS-collared lions provided location data used to construct individual movement paths, along which spatio-temporal clusters of GPS locations (n = 4896) were identified for ground investigation. Carcasses (n = 643) were recorded at the GPS clusters and scats (n = 256) were collected at GPS clusters with or without carcasses. Data from the located carcasses and scat collections were then used to create a history of feeding events for each collared lion in Main Camp-Colchester and Nyathi from a) carcasses alone or b) a combination of scats and carcasses, based on an estimated short and long lion throughout period. Relative prey availability was estimated based on camera trapping in Nyathi in high lion, low lion and no lion use areas, as lions may encounter some prey species more than other prey species. Jacobs’ index prey preference was used to investigate the importance of prey species to lion diets at three landscape scales: 1) Nyathi, 2) lion UD and 3) core lion UD. Lastly, prey population trends were investigated in Nyathi to provide an indication of possible changes in prey populations. Large prey species dominated the adjusted diets of lions in Main Camp-Colchester and Nyathi. However, when comparing the GPS carcass-derived lion diet estimate to the combined lion diet estimate, small prey were underestimated more often than large prey in the GPS carcass-derived lion diet estimate. Missed feeding events were therefore a function of prey body size. In addition, missed feeding events were also representative of the lion diets based on carcasses, with the tendency for species more often consumed to be missed more often in the diet record. However, even though small prey species were underestimated, they represented the minority of species consumed by lions and were predominantly avoided by lions in Nyathi. Lion prey preferences thus did not correlate to the declines in small prey species in Naythi, suggesting other potential drivers are important for small population trends in Nyathi. Lion predation cannot be ruled out as a driver of the decline in small prey species in Main Camp, due to different ecological conditions (e.g. vegetation density) in Main Camp compared to Nyathi, during the observed small prey population declines. Lion prey preferences in Nyathi revealed fine-scale variations in species specific preferences by lions, as well as site-specific differences in prey preferences when compared to published lion prey preference meta-analyses. These findings suggest that metaanalysis studies should be used as a guideline from which hypotheses about local predatorprey interactions can be developed rather than as an absolute measure of prey preference.

- Description: Rationale: There is limited research available in South Africa that explores the breastfeeding experience among adolescent mothers; most of the studies were conducted in developed countries. One such study relating to the above mentioned developed countries stated that social and commitment factors influence the decision to breastfeed by adolescents. Furthermore, while adolescent mothers appreciate the benefits of breastfeeding, pain, public exposure and perceived complexities related to breastfeeding create barriers for them. The researcher was unable to ascertain if similar ambiguities exist among adolescent mothers in South Africa, and in the Eastern Cape (EC) in particular with its high rates of adolescent pregnancy. In order to attempt to develop age appropriate recommendations to assist adolescent mothers with their breastfeeding journey, the researcher undertook this research study to answer the following question: What are the breastfeeding experiences of adolescent mothers in the Nelson Mandela Bay Heath District (NMBHD)? Aim: The research aim was to determine the experiences of adolescent mothers regarding breastfeeding in NMBHD. Methods: The study implemented a qualitative research approach. To enhance the design, the researcher utilised an explorative, descriptive and contextual research design. The ethical principles that guided this study were autonomy, nonmaleficence, beneficence and justice. Fourteen adolescent mothers, attending PHC facilities in the NMBHD participated in the study. Participants were chosen from a purposive sampling technique and data were collected from semi-structured interviews, compromising of individual interviews. The researcher analysed the data using the using the eight steps of the Tesch analysis technique. Data was also analysed by an independent coder. Results obtained from the Tesch approach were compared to that of the independent coder results. Thereafter, the major themes and sub-themes that related to the study objectives were identified. Results: Three themes and 10 sub-themes were identified. Lack of knowledge and poor adherence to EBF, perceived breastmilk insufficiency, as well as incorrect infant feeding advice given by maternal mothers and grandmothers were associated with early introduction of complementary feeding. Most participants were motivated to breastfeed due to its economic and bonding benefits, as well as seeing their infant‟s progress in growth. Challenges of breastfeeding mentioned by the participants include: lack of support from the fathers of their infants and from health care providers, breast milk leakage, and the foul smell associated with the leaking of breast milk. The participants of the study also had suggestions to help improve the support given to adolescent mothers by health care providers in PHC facilities. Conclusions and recommendations: In conclusion, this study‟s findings revealed that adolescent mothers may need extra age appropriate education and support to assist them in breastfeeding successfully at PHC facilities, the community and schools. Maternal mothers and grandmothers were found to be the primary source of a support network for most adolescent mothers as opposed to health care providers who were categorised as being the secondary source of support. Thus, breastfeeding promotion tailored at maternal mothers and grandmothers would be beneficial in improving their knowledge about the recommended infant feeding practices and consequently aid in providing appropriate support and advice to adolescent mothers. Additionally, training and attitude modification of health care providers is needed to provide adolescent mothers with age-appropriate, effective and sensitive care and counselling.

Conclusions and recommendations: In conclusion, this study‟s findings revealed that adolescent mothers may need extra age appropriate education and support to assist them in breastfeeding successfully at PHC facilities, the community and schools. Maternal mothers and grandmothers were found to be the primary source of a support network for most adolescent mothers as opposed to health care providers who were categorised as being the secondary source of support. Thus, breastfeeding promotion tailored at maternal mothers and grandmothers would be beneficial in improving their knowledge about the recommended infant feeding practices and consequently aid in providing appropriate support and advice to adolescent mothers. Additionally, training and attitude modification of health care providers is needed to provide adolescent mothers with age-appropriate, effective and sensitive care and counselling.

- Description: Conservation agriculture (CA) has been widely recommended as one of the best ‘climate smart’ agriculture (CSA) practices in many regions of Africa and beyond. It helps to cushion smallholder farmers from the impacts of climate variability and change manifested through erratic rainfall, prolonged dry spells and droughts. CA is a preferred strategy for rehabilitating degraded agricultural land by improving its soil health for optimal crop production. However, adoption and upscaling of this farming practice in many African countries, which face critical challenges of food insecurity and soil degradation, including Malawi, is not significantly expanding despite these established benefits. This participatory action research study therefore explored factors limiting CA adoption and upscaling among the smallholder farmers in Khombedza Extension Planning Area where Total LandCare, the Malawian Ministry of Agriculture and other NGOs have been supporting farmers to adopt CA practices for more than five years. Participatory approaches were used throughout the research process for data collection, with farmers acting as co-researchers as they are best placed to identify the farming challenges and recommend solutions. Key informant interviews and field observations complemented and validated some of the results from the participatory rural appraisal (PRA) activities. The study findings revealed a number of factors behind low CA adoption and upscaling, with many relating to the poor extension system promoted by NGOs and government extension staff. Other factors relate to farmers’ perceptions and are linked to the CA system itself. The on-farm participatory training clarified the majority of farmers’ understanding and changed their mindset towards CA practices, which in turn increased its visibility in terms of adoption and scale of upscaling across the villages under study. In trying to address the poor extension system, as observed and reported by the majority of participants, the research practically tested a “Farmer Neighbourhood (FN) model”, which provided a greater opportunity for farm level interactive learning and provision of better farmer-to-farmer and farmer-to-field staff extension support. The majority of participants and field staff, as well as members of the National Conservation Agriculture Task Force (NCATF) in Malawi, made a recommendation to replicate this model of targeting and supporting farmers in order to increase CA visibility throughout the country. Participation and interactive farmer learning emerged as major themes, which guided successful implementation of the research whilst addressing the research questions and objectives.

- Description: The range and use of ecosystem services provided by urban sacred sites has hardly been considered in studies of urban ecology, sustainability and human wellbeing. This paper examines the perceived ecosystem services supplied by green spaces or gardens associated with places of religious worship and appreciated by worshippers in a mid-sized town in South Africa. A questionnaire with open, closed and Likert scale questions was administered at 30 places of worship (25 with gardens and five without). Respondents identified a wide diversity of ecosystem services provided by gardens, with social ones being more recognized than ecological, and economic services the least. Approximately two-thirds of respondents visited a sacred site garden weekly or more often. The majority of respondents (96%) felt that a garden was necessary because it added to their feelings of connection with God, or helped them relax and so be better able to concentrate, and 54% stated that a garden enhanced their overall spiritual experience. Regression analysis revealed that aesthetic appreciation of a garden was significantly related to woody plant species richness, number and basal area in the garden. On the other hand, spiritual experience was positively related to woody plant basal area, but not species richness nor tree number. Neither size of the garden, nor number of years the respondents had been vising a particular sacred site had any influence on the rated spiritual or aesthetic experiences. These results reveal the widely appreciated ecosystem services provided by urban sacred spaces and their centrality in enhancing spiritual satisfaction for some.

- Description: The purpose of this treatise is to develop a spirit of understanding affirmative action as a strategy that gives South Africa a human face of equality. The strategic development of affirmative action as part of Employment Equity Act is based on equality at workplace. This work takes note of the need to integrate human resource development for employment, productivity and education system that is based on formal education, prior knowledge education (RPL) and previous experience. The imbalances were designed to be of racial reflection therefore the redress process is racial in character but non-racial in content as the envisaged society is a non-racial society. The historical background of inequality and racial discrimination is noted in the environment of employment and on how other laws were enforcing the inequality. The arguments against affirmative action are debated and valid points of such arguments are noted as points of concern that must be considered in the process to attain equality. This work views affirmative action as a process that goes beyond employment relations and work as an instrument to change society by addressing social needs and services that have a reflection of inequality. Education is viewed as the out most important process to change the lives of people as affirmative action has a requirement of suitably qualified candidates to be affirmed. In South Africa problems of inequality were political designed but were enforced by various laws that were having material and psychological impact on the previously disadvantaged. The designated groups were divided into Africans, Indians and Coloureds, in Naidoo v Minister of Safety and Security this principle of defining designated racial groups was promoted in correction to the direction that was taken in Motala v University of Natal.Affirmative action is a legal process that addresses political designed problems. It is also a process that is exposed to abuse. Corrupt officials and managers appoint employees that do not qualify for posts on the bases of political affiliation or any other ground of discrimination. This is discussed with reference to the allegations of SADTU selling posts for principals, senior managers appointed in state co-operatives. The above mentioned tendencies are noted as part of negative indicators on the process that is meant to bring equality and non-racial society where all the citizens are given equal opportunities. This work views affirmative action as a strategy that is based on achieving a society that has a human face where race shall not be a point of reference.

Agribusiness challenges to effectiveness of contract farming in commercialisation of small-scale vegetable farmers

- Description: The spread of contract farming in South Africa in recent years has provoked an ideological debate in literature. Linking small-scale vegetable farmers with lucrative agricultural markets through agribusiness value chains is seen as one of the foremost emerging agricultural practices to develop the subsistence farming sector into a mainstream economic sector – thereby revitalising the rural economy and alleviating poverty levels in the developing rural areas of South Africa. However, the challenges agribusiness and small-scale farmers experience in contract farming engagement and the prospects for enhancing the inclusion of small-scale farmers into modern value chains remain open to debate – two decades after transition to democracy. Yet the factors and mechanisms influencing the effective application of contract farming in the transition to commercial farming by small-scale farmers have not been thoroughly explored in South African research. Despite the efforts and the substantial investments made and the various policies and initiatives instigated to fast-track the linkages of small-scale farmers into high-value markets, the success stories of previously disadvantaged farmers operating in commercial agri-food chains are rare. Given the millions of small-scale farmers in former homelands alone, the negligible number of small-scale farmers successfully operating in commercial agri-food chains shows that the objectives to enable small-scale farmers to improve their livelihoods through participation in commercial agri-food chains have not yet been met. The broad objectives of the study were therefore to investigate the agribusiness challenges inherent in contract farming and the conditions and incentives required by agribusiness firms to engage small-scale vegetable farmers in contract farming programmes. Furthermore, the study examined the role played by the South African government to reduce the high transaction costs incurred by agribusinesses when engaging small-scale farmers in contractual arrangements. The Amathole and Sarah Baartman (formerly Cacadu) district municipalities in the Eastern Cape Province of South Africa were chosen as the composite survey area for this study. A predominantly qualitative research approach was applied to gather data on the phenomena under study. The following methodologies and research instruments and tools were selected. Firstly – as the secondary component of the research – a systematic review of literature to date was conducted to guide the empirical research and primary methodology. Secondly, the empirical component of the study comprised a questionnaire survey, unstructured interviews and focus group discussions. The questionnaire survey was used to collect data from the agribusiness firms in the area surveyed concerning the following aspects: the significant determinants of contract farming, the incentives required by the agribusiness firms to engage small-scale vegetable farmers in their contract farming programmes and the challenges faced by agribusiness firms in their interaction with small-scale farmers in contractual arrangements. Unstructured interviews were used to gather data from officials at each of the three levels of government – the Department of Rural Development and Land Reform nationally, Department of Agriculture and Land Reform provincially and (at local government level) two district municipalities – on the role played by government to reduce the high transaction costs incurred by agri-firms when procuring agricultural raw materials from small-scale vegetable farmers. Focus group discussions were conducted with small-scale farmers regarding their perspective on working with agribusiness firms and to establish the distinguishing characteristics of small-scale farmers in the area surveyed. Relevant policy documents collected from two of the three representative groups of the study population, i.e. agribusiness personnel and government officials, provided the essential context. The study revealed a limited number of contract farming business linkages between small-scale vegetable farmers and agribusiness firms in the survey area. Those that do exist are problematic to both the agribusiness firms and the small-scale farmers. It emerged that the contract farming environment in the area surveyed is highly polarised and characterised by a fundamental conflict of interest between agribusiness and farmer. Among the divergent key factors inhibiting contract farming engagement were a lack in terms of quality seeds, trust, entrepreneurial skills and formal contract agreements. Asset endowment (both land and non-land assets) was found to be significant pre-selection determinants in the farmer’s capacity to be contracted. Access to innovative technology, as well as government incentives such as production inputs, were found to be critical to agribusiness firms to engage smallscale farmers in their contract farming programmes. Government assistance in terms of high transaction costs to agribusiness firms working with large groups of small-scale farmers was found to be essential but inadequate under current policy. This impacts directly on the effectiveness and promotion of contract farming. Furthermore, the current results corroborate the findings of numerous South African studies in the vast body of worldwide research. Firstly, lack of land and non-land assets continue to be major impediments to the direct participa-tion of small-scale farmers in contract farming programmes and, secondly, the transaction and market information costs incurred by agribusiness prevent the participation of less endowed farmers in contract farming programmes. Conducted within the interpretivist paradigm, the explorative research identified wide-ranging challenges in the relationship between agri-business and small-scale farmers which directly impact the effective-ness of contract farming as a development and agrarian reform strategy. Despite their problematic relationship, however, agribusiness and small-scale contract farmers were in agreement that the government needs to expand its support for agri-firms to incentivise greater numbers of small-scale farmers having the opportunity to achieve commercial status through contract farming. The study therefore recommends a collaborative partnership between private firms and government, with state support through revised policies and development programmes. These amendments are crucial to enhancing the engagement of small-scale vegetable farmers in lucrative agri-food chains.

- Description: This study investigates the impact of urban agriculture in the city of East London as well as the possibility of adopting agricultural urbanism as an urban farming model to bolster food security. The study goes further to understand the role that could be played by University of Fort Hare and Buffalo City Metropolitan Municipality in capacitating small scale urban farmers in the city of East London. Unemployment and food insecurity are the key challenges that are affecting many families in South Africa, including urban dwellers. The main objective of this study therefore is to investigate the contributions of urban farming in securing food security and livelihoods in East London. This study adopted a mixed methods research approach, where both quantitative and qualitative methods were used to harvest data. Statistical analysis (descriptive) was then used to analyse quantitative data. Thematic approach used to analyse qualitative data. The study shows that urban farming plays an important role in the livelihoods of urban dwellers. However, the sector still faces various challenges such as lack of recognition by authorities. The study also revealed that the city of East London has potential to establish agricultural urbanism as it has most of the essential aspects that are necessary to establish it. The study recommends strengthening of the partnership between University of Fort Hare, Buffalo City Metropolitan Municipality and small scale urban farmers in East London.
