- Description: An ethnobotanical survey was conducted in Alice and Willowvale in the Nkonkobe and Mbashe municipalities of the Eastern Cape Province, South Africa to identify and document wild vegetables growing in the areas. The survey documented 22 vegetable species belonging to 12 different families. The Amaryllidaceae, Amaranthaceae, Apiaceae, Asteraceae, Caryophyllaceae, Chenopodiaceae, Convolvulaceae, Cruciferae, Cucurbitaceaea, Euphorbiaceae, Tiliaceae, Solanaceae, Polygonaceae and Urticaceae were the families that were recorded. The species were Tulbaghia violacea Harv., Amaranthus blitoides S., Amaranthus blitum L., Amaranthus hybridus L., Centella coriacea Nannfd., Bidens pilosa L, Cotula heterocarpa DC., Sonchus oleraceus L., Galinsoga parviflora Cav., Taraxacum officinale Weber, Hypochaeris radicata L., Stellaria media L., Chenopodium album L., Chenopodium murale L., Ipomoea batatas L., Sisymbrium thellungii O. Schulz, Cucurbita pepo L., Rumex crispus L., Acalypha virginica L., Nicandra physalodes L., Physalis peruviana L., Solanum nigrum L., Urtica urens L. and Corchorus olitorius L. About 27 % of the wild vegetables were native to South Africa and about 45 % were also used as medicinal plants in the areas. Sun drying was the most common method of preserving the wild vegetables for the off season months. This study also revealed that, men and the younger generation knew less about wild vegetables than the women. The study also revealed a loss of knowledge of wild vegetables and their use by the rural dwellers who are more in favour of the exotic types such as spinach and cabbage.

- Description: This book explores, at a time when several powers have become serious players on the continent, aspects of African agency, past and present, by African writers on foreign policy, representative of geography, language and state size. In the past, African foreign policy has largely been considered within the context of reactions to the international or global 'external factor'. This ground-breaking book, however, looks at how foreign policy has been crafted and used in response not just to external, but also, mainly, domestic imperatives or (theoretical) signifiers. As such, it narrates individual and changing foreign policy orientations over time - and as far back as independence - with mainly African-based scholars who present their own constructs of what is a useful theoretical narrative regarding foreign policy on the continent - how theory is adapted to local circumstance or substituted for continentally based ontologies. The book therefore contends that the African experience carries valuable import for expanding general understandings of foreign policy in general. This book will be of key interest to scholars and students of Foreign Policy Analysis, Foreign Policy Studies, African International Relations/Politics/Studies, Diplomacy and more broadly to International Relations. , Introduction / Paul-Henri Bischoff -- What Next?

- Description: The purpose of the study was to determine the factors influencing participation in Employee Health and Wellness programmes rendered by South African Police Service. Qualitative method was used and case study design was chosen. Data was collected from twenty-two participants. Semi structured interviews was used as an instrument to collect data. Interpretivism paradigm was followed for data analysis. The findings of this study revealed that participation in EHW Programmes is indeed low at Mdantsane Accountable Police Station. Most of the participants did not show any interest in the services rendered by SAPS. Their belief systems and perceptions about EHW Programs are a contributing factor to the non-utilisation of the services. One major factor that was identified by this research was the impact police training has on the decisions police members make to participate or not to participate in EHW Programmes. SAPS is a male dominated organisation, with employees that are rooted in cultural beliefs. Some participants, especially men mentioned that it is against their culture to talk about their personal problems to strangers, referring to EHW Professionals, others believed that seeking professional help from a female professional is a sign of losing your manhood an indication that you are weak. With this kind of personal belief, the researcher is of the view that SAPS has to consider adopting a new EHW Model, a model that will be relevant to the objectives of SAPS. Engaging police officers in physical activities will be more effective in promoting participation because Police work requires that police members need more than just task competencies or technical knowledge to do their work (Turner, 2014), they need to be physically fit in order to protect themselves and the community they are serving. Engaging them in counselling and educational programmes will not increase participation since they regard such services to be meant for the weak police officers.

- Description: The use of the yield curve in forecasting economic recessions is well established in the literature. A new avenue of use for the yield curve has emerged in the form of using it to forecast bull and bear stock markets. This has the potential to change how investors manage portfolios. A dynamic market-timing strategy would allow investors to shift out of or in to stock markets based on the probability of bear stock market in the future. The relationship between the yield curve and the stock market is tested using an adapted probit model. This has proven positive with encouraging results for the US, India and Spain. This is tested for South Africa using the adapted probit model and the SA yield spread. Bear stock markets are identified on the JSE and forms part of the probit modelling process. Bear markets are identified using a six- and four-month criteria. As South Africa is a small, open and developing economy, the probit is also modelled using the US yield spread. The three probit models do not appear to track bear markets well. This is substantiated through the Henriksson-Merton parametric model test which tests for market timing ability. The results for the SA yield spread using both bear market criteria do not show market timing ability, however, the SA and US yield spread model does show potential market timing ability.

Factors that make a visit to selected Eastern Cape national parks a memorable experience

- Description: South African National Parks (SANParks) manages 19 functional national parks (NPs) and oversees the conservation of South Africa’s (SA’s) biodiversity, landscapes and heritage assets. The organisation plays a significant role in the promotion of SA’s nature-based tourism business which in turn forms part of the nation’s heritage and identity. Tourism to SA’s NPs is significant and interest in visiting these parks continues to increase annually, from both international and domestic markets. Three of these NPs are located in the Eastern Cape province, namely Addo Elephant National Park (AENP), Camdeboo National Park (CNP) and Mountain Zebra National Park (MZNP) and were the focus of this study. The main reason for conducting the current study was to establish what factors make visits to the three aforementioned NPs memorable. The findings of this research could be useful to all NPs and assist them in making decisions regarding the evaluation and creation of product offerings that will enhance experiences and make them memorable for tourists. Based on the findings, and because each NP is unique (for example, the different biodiversity and landscapes), the product offerings can also be made exclusive to each NP and therefore tourists can have the opportunity for different MTEs in each park. Providing product offerings that afford MTE opportunities are particularly important for NPs, as government funding is decreasing and each NP needs to generate its own funds. Tourism is presently the economic lifeline for the parks. If NPs focus on improving current products where necessary and developing new products that provide for MTEs, NPs could increase their competitive advantage. Having a competitive advantage can ensure an increase in tourism numbers and therefore the financial sustainability of the park. Data was collected on site at each of the three NPs selected for the study, using convenience sampling to select respondents. A web-based survey was also posted on the SANParks’ website. Prior to the posting of the web-based survey, SANParks conducted a simple random sampling procedure utilising a sampling frame of tourists who had previously visited the respective NPs. The selected target population emanating from simple random sampling was e-mailed the link to the SANParks website which guided respondents to the online questionnaire if they wished to take part in the survey, hence the response sample was a convenience sample. In total, 463 usable questionnaires were received. Descriptive statistics resulted from the data analysis. A frequency analysis showed the distribution of the results, while an exploratory factors analysis (EFA) was conducted to ascertain any latent factors in the data. The results of the EFA showed the presence of three latent factors which were labelled Pleasure, Social Interaction and Discovery and Enrichment. Firstly, a strong positive correlation was shown between two of the factors, namely Pleasure and Discovery and Enrichment, and secondly, a positive correlation between two other factors, namely Social Interaction and Discovery and Enrichment was indicated. A weak correlation was shown between the factors Pleasure and Social Interaction. This research has contributed to the knowledge base regarding the factors that make a visit to AENP, CNP and MZNP memorable. Future research can make use of these factors for more exhaustive research in a wider range of NPs.

- Description: In this dissertation, the socio-ecological transformations that occurred during Cuba’s Revolución Agrícola are explored, against the backdrop of the historical subalternisation of the country as a consequence of Spanish and American imperialism, and in relation to the continuing subalternisation of the country and its people through the neoliberal mass media. To contextualize such exploration, the origins of large-scale privatization of common land, and the subsequent process of urbanization in the West, are investigated, before Cuba’s similar developmental path – as a result of Spanish colonialism, U.S. imperialism, and communist influence – is detailed. Thereafter, the way in which Cuba established an alternative food paradigm, characterised by local, communal, and urban production during the country’s ‘Special Period’ in the 1990s, is discussed, with a view to illustrating how this eco-socialist model of food production, in both rural and urban areas, led to new relations between people and nature. This Cuban model is then posited as a socio-ecologically sustainable model of food production, deserving of the attention of communities around the world, who seek to gain a degree of autonomy from neoliberal agribusiness. Conversely, the efforts of mainstream neoliberal mass media to silence the immensely positive characteristics of the revolution are also investigated, and framed in terms of the historical subjugation of Cuban voices in the American mass media, and the contemporary marginalisation of the country and its people in the neoliberal mass media. Finally, the dissertation concludes by examining the alternative media response, on the part of several prominent Cubans and those sympathetic to their cause, to bring attention to the value of the socio-ecological transformations that have occurred on the island, against the backdrop of various theorisations of the importance of alternative media platforms as a radical counterforce to neoliberal mass media hegemony.

- Description: In this dissertation, the socio-ecological transformations that occurred during Cuba’s Revolución Agrícola are explored, against the backdrop of the historical subalternisation of the country as a consequence of Spanish and American imperialism, and in relation to the continuing subalternisation of the country and its people through the neoliberal mass media. To contextualize such exploration, the origins of large-scale privatization of common land, and the subsequent process of urbanization in the West, are investigated, before Cuba’s similar developmental path – as a result of Spanish colonialism, U.S. imperialism, and communist influence – is detailed. Thereafter, the way in which Cuba established an alternative food paradigm, characterised by local, communal, and urban production during the country’s ‘Special Period’ in the 1990s, is discussed, with a view to illustrating how this eco-socialist model of food production, in both rural and urban areas, led to new relations between people and nature. This Cuban model is then posited as a socio-ecologically sustainable model of food production, deserving of the attention of communities around the world, who seek to gain a degree of autonomy from neoliberal agribusiness. Conversely, the efforts of mainstream neoliberal mass media to silence the immensely positive characteristics of the revolution are also investigated, and framed in terms of the historical subjugation of Cuban voices in the American mass media, and the contemporary marginalisation of the country and its people in the neoliberal mass media. Finally, the dissertation concludes by examining the alternative media response, on the part of several prominent Cubans and those sympathetic to their cause, to bring attention to the value of the socio-ecological transformations that have occurred on the island, against the backdrop of various theorisations of the importance of alternative media platforms as a radical counterforce to neoliberal mass media hegemony.

- Description: Early stage fishes (larvae and early juveniles) were collected from an array of shallow water (±1.5m) habitats on the warm-temperate southern Angolan coastline between June 2014 and June 2015. This study, the first assessment of the early stages of coastal fishes in Angola, provides important new understanding of non-estuarine shallow water nursery habitat use by coastal fishes from the region. In total, 51 species from 18 teleost families were observed. The exposed surf zone was dominated by postflexion larvae, while the moderately exposed beach and sheltered bay were dominated by early juveniles. Both fish density and diversity peaked in the wet season (Feb – Apr 2015) for all habitats, attributed to the influx of summer spawning species. Diplodus sargus dominated catches from the exposed surf zone, and the timing of observations supports the growing consensus that sparid spawning is dictated by temperature, not season. The similitude of the observed species to those observed in warm temperate South Africa highlights the historical connection of the warm-temperate study area with warm-temperate South Africa, prior to the formation of the Benguela Current as a vicariant barrier. The classification of the study assemblage into established estuarine utilization categories showed that the surf zone hosted more exclusively marine species than comparable surf zones in South Africa, attributed to the absence of estuaries in southern Angola. However, the observation of the marine estuarine dependent Mugil cephalus in this study area devoid of estuaries suggests that estuarine dependency may be regionally specific for some taxa. It appears that the warm, sheltered, nutrient rich waters of Tombua Bay provide typically estuarine associated taxa with a suitable alternative, non-estuarine nursery habitat. This study provides evidence that the importance of estuaries as critical nursery habitats has been overemphasized for some warm-temperate coastal fishes. However, the absence of other marine estuarine dependent species from the study area suggests that some warm-temperate taxa do intrinsically rely on estuarine function for survival.

- Description: The effects of different redox mediators on the oxygen reduction reaction (ORR) catalyzed by an iron porphyrin complex, iron(III) meso-tetra(N-methyl-4-pyridyl)porphine chloride [FeIIITMPyP], in 0.1 M triflic acid were investigated by cyclic voltammetry (CV) and spectroelectrochemistry in conjunction with density functional theory (DFT) calculations. The formal potentials of the FeIIITMPyP catalyst and the redox mediators, as well as the half-wave potentials for the ORR, were determined by CV in the absence and presence of oxygen in acidic solutions. UV/Vis spectroscopic and spectroelectrochemical studies confirmed that only the 2,2′-azino-bis(3-ethylbenzothiazioline-6-sulfonic acid)diammonium salt (C18H24N6O6S4) showed effective interactions with FeIIITMPyP during the ORR. DFT calculations suggested strong interaction between FeIIITMPyP and the C18H24N6O6S4 redox mediator. The redox mediator caused lengthening of the dioxygen iron bond, which thus suggested easier dioxygen reduction. Consistent results were observed in electrochemical impedance spectroscopic measurements for which the electron-transfer kinetics were also evaluated.

- Description: The periodicity of formation of growth increments in the otoliths of South African sparids was validated by the oxytetracycline labelling technique. Intramuscular injections of oxytetracycline at a dosage of 250mg/kg marked the otoliths of laboratory held juvenile sparids, while a dosage range of 50 - 100mg/kg oxytetracycline, injected intramuscularly, marked adult sparids in the field. Laboratory held, larval sparid otoliths were marked by immersion for 24hrs a solution of 100-150mg/l alizarin complexone. Both daily (microstructural) and annual (macrostructural) growth increments were identified in the otoliths. The micro incremental pattern of deposition in the sparid otoliths conformed to the general pattern of otolith structure. Sparid otoliths consisted of a central opaque nucleus composed of multiple primordia. surrounding this nucleus were daily increments which decreased in width as the distance from the nucleus increased. Both check rings and subdaily increments were visible throughout the otolith. Minor environmental changes did not affect micro incremental deposition. Narrow opaque and wide hyaline annual growth zones were identified in sectioned sparid otoliths. Scanning electron microscope analysis of the annual growth zones revealed that microincrements within the opaque zone were narrowly spaced with prominent discontinuous phases. This resulted in the greater optical density and higher protein content of the zone. The hyaline zone was composed of widely spaced daily increments with prominent incremental phases accounting for the translucent nature of this zone. Opaque zone formation in the otoliths of many South African sparids was found to occur primarily during periods of reproductive activity and was shown to be indicative of slow otolith growth. The hyaline zone was formed after the spawning season, representative of fast otolith growth. The results of this study have resolved much of the controversy surrounding the rate of growth and time of formation of the opaque and hyaline growth zones in South African sparid otoliths.

- Description: This research sought to analyse factors that affect media freedom at the South African Broadcasting Corporation using a descriptive research design and qualitative research methodology. Studies and media reports show that the South African Broadcasting Corporation is facing a myriad of challenges including woes related to media freedom hampering its mandate to inform, educate and entertain the public of South Africa. There is a dearth of studies conducted to understand the media freedom challenges at the South African Broadcasting Corporation. A qualitative approach was used in data collection, and in-depth interviews were utilised as instruments to collect data from participants. Non-probability sampling in particular purposive sampling method was used to select 4 directors, 4 editors and 4 journalists at the South African Broadcasting Corporation. Data was analysed using thematic analysis. The findings show that challenges facing the South African Broadcasting Corporation include poor legal environment as the broadcaster lacks support from government to implement effective policies to protect employees and create a media freedom environment to allow workers to carry out their work independently. The study found that the political environment in the South African Broadcasting Corporation at affects media freedom. Some political 0rganisations, influential individuals and entities are meddling in the operation of the broadcaster by trying to influence the narrative of the content broadcasted. The finding revealed that economic environment at the broadcaster is affects media freedom. The broadcaster is struggling financially resulting in poor income for employees, retrenchments, and inability to run approved programmes. In the context of constitution and policies, there is need for the South African Broadcasting Corporation to develop strategies that will specifically address both internal and external political, economic, and legal challenges it is facing if it is to be a high performing, financially sustainable, digitised national public broadcaster that provides compelling, informative, educational, and entertaining content via all platforms. , Thesis (MA) -- Faculty of Humanities , School of language Media and Communications, 2022

- Description: The objectives of the study were to determine the effects of grazing systems on rangeland biomass yield and nutritional composition, tick and faecal egg counts in beef cattle across seasons. The study was conducted at Merino Walk farm located in Matatiele in the northern part of the Eastern Cape Province, South Africa. The farm was divided into three experimental plots of 3.5 ha each. Thereafter, three grazing treatments namely, Holistic Planned Grazing (HPG paddocks), Four-camp rotation (FCR) and continuous grazing (CG), were randomly allocated to the experimental plots. In the FCR system, the 3.5ha was subdivided into four 0.875-ha paddocks, while the HPG system was subdivided into ninety (90) 0.039-ha paddocks. Common forages were hand-clipped at a grazing height of (5cm) in the wet and dry season from six quadrats (0.25m2) placed in each plot and evaluated for biomass yield and nutritional composition. Thirty (30) steers of the same age 12-month old of similar weight were randomly allocated to three grazing treatments (10/treatments). Tick counts were recorded for each steer in the hot-wet, hot-dry, post-rainy and cold dry seasons. Faecal samples were collected per-rectum every in four seasons and analysed for faecal egg counts using the modified McMaster method. The data were analysed using PROC Generalized Linear Model of SAS (2012) to determine the effects of grazing system on rangeland biomass yield, nutritional composition, tick and faecal egg counts. The common grass species in all grazing system across season were Cynodon dactylon, Eragrostis chloromelus, Eragrostis plana, Fescuta and Themeda triandra. The FCR system in the wet season had significant the lowest (P<0.05) biomass yield of 62605,33kg/ha compared to other treatments which had mean values of 62625,97 and 62625,89kg/ha for HPG and CG, respectively (P<0.05). Crude protein content was higher (P<0.05) in HPG (9.41percentCP) and FCR (9.22percentCP) systems in the wet season compared to CG across seasons. Forage from HPG system, irrespective of season had significant lower starch content than other treatments (P<0.05). Forage from HPG system, irrespective of season had the lower (P<0.05) starch content than other treatments. Regardless of season, CG had higher (P<0.05) NDF (72.51 and 72.50) and ADF (41.93 and 40.45) contents than FCR and HPG treatments. Overall, HPG system regardless of season and FCR in the wet season had higher (P<0.05) in vitro digestibility at 24 and 48hrs (0.38 and 0.66) incubation periods. The tick species identified were Rhipicephalus evertsi evertsi, Rhipicephalus (Boophilus) decoloratus, Hyalomma spp and Amblyomma hebreaum with respective prevalence’s of 32percent, 29percent, 20percent and 19percent. Unidentified roundworms (URW), had the highest faecal egg counts (81.2percent) followed by Coccidia (16.4percent), Nematodirus (1.2percent) and Strongyles (1.2percent). Overall, steers on the CG system during hot-wet season had the highest individual and total tick counts (17.0) whilst those on FCR during the cold-dry season had the lowest counts (6.0). Holistic Planned Grazing had the lowest worm egg counts regardless of season, while CG had the highest counts in the hot wet season (P<0.05). The findings showed that relative to other treatments, the HPG system in wet season had a higher biomass yield and better nutritional composition (high CP, low fibre and high digestibility) with low forage production and quality under CG system during the cold-dry season. Whilst, CG during hot-wet season had the highest total tick and worm egg counts and least counts under HPG during the cold-dry. Based on relatively higher forage production and low parasite loads, HPG could be a better grazing management system than CG and FCR, especially in the wet season. It may be important to evaluate the effect of HPG on animal production, product quality and profitability prior to recommending it for use by farmers.

- Description: This treatise investigates how information technology (I.T.) enables growth in a family business (the firm) in Port Elizabeth. The firm operates in the mobile telecommunications sector. The objective of the study is to gain a deeper understanding on why family businesses adopt information technology in their firm by means of a case study. The firm found its technology (or lack thereof) completely out-dated compared to the competition and customer demands. The future of the firm was in jeopardy. The study starts with a literature review of the following three topics which form part of the scope of the research: 1. Family businesses; 2. Influence of I.T. as a driver of growth in business; and 3. An introduction into the mobile telecommunications industry. Data are collected through structured interviews with family members involved in the business. The data are consequently linked to the theory and provides insight as to what the drivers are for I.T. adoption and the required core competencies or critical success factors of the firm. Although it might seem trivial for a small family business to adopt information technology, the research concludes that I.T. is critical for continuous growth and survival of this family business. Conversely due to a lack of internal skills the firm is heavily reliant upon outside consultants for advice, implementation and support. Recommendations which are of particular interest to family businesses in a similar environment are: • Embrace technology early, utilise I.T. solutions to grow and enhance current competitive advantage, do not see I.T. as a competitive advantage alone (Pavlou & Sawy, 2006); • If information expertise is not present within the company it is advisable to invest in that expertise through recruitment, training, partnership, or outsourcing; • Ensure software meets specification / is effective enough – this can be achieved by frequent releases cycles with small changes instead of infrequent release cycles with many big changes; • Engage the consultants in a partnership by i.e. providing a profit share – this will ensure that the consultants are committed to the cause and will also ensure that their involvement is also in their own best interest; • Choose local consultants who are easily accessible – build relationships and focus on trust; • Create lock-in (Amit & Zott, 2001), provide tools free-ofcharge for customers, this will make switching to competitor more difficult; • Automate as much as possible, enable standard work practices, routinize; • Be ready to adjust the organisational structure or relinquish control (Bruquea & Moyanob, 2007)

Influence of I.T. as a driver of growth in business; and 3. An introduction into the mobile telecommunications industry. Data are collected through structured interviews with family members involved in the business. The data are consequently linked to the theory and provides insight as to what the drivers are for I.T. adoption and the required core competencies or critical success factors of the firm. Although it might seem trivial for a small family business to adopt information technology, the research concludes that I.T. is critical for continuous growth and survival of this family business. Conversely due to a lack of internal skills the firm is heavily reliant upon outside consultants for advice, implementation and support. Recommendations which are of particular interest to family businesses in a similar environment are: • Embrace technology early, utilise I.T. solutions to grow and enhance current competitive advantage, do not see I.T. as a competitive advantage alone (Pavlou & Sawy, 2006); • If information expertise is not present within the company it is advisable to invest in that expertise through recruitment, training, partnership, or outsourcing; • Ensure software meets specification / is effective enough – this can be achieved by frequent releases cycles with small changes instead of infrequent release cycles with many big changes; • Engage the consultants in a partnership by i.e. providing a profit share – this will ensure that the consultants are committed to the cause and will also ensure that their involvement is also in their own best interest; • Choose local consultants who are easily accessible – build relationships and focus on trust; • Create lock-in (Amit & Zott, 2001), provide tools free-ofcharge for customers, this will make switching to competitor more difficult; • Automate as much as possible, enable standard work practices, routinize; • Be ready to adjust the organisational structure or relinquish control (Bruquea & Moyanob, 2007)

- Description: Several studies have assumed that the plant communities of the Subtropical Thicket biome are nutritious throughout the year. This is based on the observation that they are evergreen, palatable and grow on fertile soils; however this assumption has not been tested. Therefore the aim of this study was to assess forage quality variation in the Subtropical Thicket. This was done at three levels; first we measured the plant quality of dominant plant species in the diets of Thicket herbivores. Secondly, we measured the realised diet quality of Thicket herbivores through the analysis of faecal samples. Lastly we assessed the body condition of Thicket herbivores. The study was conducted at the Colchester (plant quality and diet quality) and Addo Main Camp (body condition assessment) sections of Addo Elephant National Park. To measure the food quality of Thicket plants we analysed 10 plants that are dominant in the diets of Thicket herbivores. To measure diet quality we collected faecal samples from ten herbivores with body mass ranging from 25 kg to 6000 kg. Plant quality results showed that only 30% of the sampled plants met the high energy goat diet protein requirements and that all the sampled plants did not meet the high energy goat diet fibre requirements. This indicates that Thicket plants are not as highly nutritious as they were thought to be. The principle components analysis together with overlapping confidence intervals showed that there was no significant difference between the summer plant samples and the winter plant samples. The faecal quality results showed that there was significant seasonal difference and that faecal diet quality was a function of body size. The body condition results showed that all the sampled herbivores lost condition in the cold dry months. The evidence from faecal diet quality and body condition assessment is sufficient for us to reject the assumption that Thicket forage is consistently nutritious throughout the year. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: The African Coelacanth Ecosystem Programme (ACEP) was established in 2002 after the discovery of a colony of coelacanths off the Maputaland coast at Sodwana Bay, KwaZulu Natal. The environmental education and awareness sub-programme developed learning support materials (LSM's) for use in schools and the materials were disseminated annually through teacher education workshops. This study aimed to uncover the use of these LSM's in the rural schools of Maputaland. The active learning framework was used to analyse the materials. Collectively, the ACEP materials cover a range of active learning aspects; however alignment with the curriculum has resulted in an increased focus on experiments, accompanied by a loss of environmental content and a narrowing scope for active environmental learning. Workshop questionnaires and four school case studies revealed the patterns of practice of use of materials in schools. The stated use of materials by teachers is not fully realized in the actual classroom practice which centres on learning content and concept definitions. There is no culture of use of materials in the schools following the annual introduction of ACEP materials. It was also found that the marine and coastal knowledge holding power is outside the realm of the teachers' practice and control. The findings of this study come at a time when there is uncertainty over the future of South African education and the curriculum. This research may inform the environmental education and coastal and marine education field as to their role in education and more specifically the development of learning support materials.
