- Description: There has been an increase in the number of viral outbreaks in the last decade; the majority of these are attributed to insect-human or animal-human transfer. Despite this awareness, there is limited understanding of the replication biology of the viruses causing the outbreaks and there are few model systems that are available to study RNA virus replication and viral persistence. In this study, we describe a Providence (PrV)-based model system to study virus replication biology. PrV is a single-stranded RNA virus that can cross Kingdom boundaries; it is capable of establishing a productive infection in insect and mammalian cell culture and it is also capable of replicating in plants. Only one other virus has been reported to infect a similar host range - the Nodavirus, Flock House virus (FHV). First, we performed a bioinformatic analysis of the PrV genome and validated the tools that were currently available to work with this model system in mammalian cells. Our data indicate that PrV infection of human cervical cancer (HeLa) cells results in the production of p130, p104/p40 and VCAP, albeit at low levels. While PrV replication in insect cells is associated with the Golgi apparatus and secretory vesicles, in HeLa cells, PrV replication is associated with the mitochondria. It is interesting to note that FHV replication factories are located on the outer mitochondrial membrane. In an attempt to study PrV virus replication in vitro, we adapted the BioID system reported by Roux et al. (2012). Here a promiscuous biotin ligase enzyme (BirA) was fused to a protein of interest and the expression of the fusion protein in mammalian cells resulted in the proximitybased biotinylation of proteins associated with the protein of interest. Using p40 as the protein of interest, we studied the fusion protein (BirA-p40) in transiently transfected HeLa cells and in a stable cell line, using western blot analysis and confocal microscopy. We faced challenges comparing the data collected using the two antibody-based detection techniques and the lack of BirA-p40 detection when using western analysis was attributed to the associated of p40 with detergent resistant membranes. BirA-p40 was subsequently expressed using in vitro coupled transcription/translation reactions, in the presence of excess biotin. While BirA-p40 was robustly expressed under these conditions, biotinylation of BirA-p40 was not detected. We attributed this to the conditions used in the experiments and given additional time, we would extend the duration of biotinylation, in vitro. PrV replication in mammalian cells was detectable using confocal microscopy however the levels of fluorescence were relatively low. The knowledge that p40 was associated with detergent resistant membranes led us to question the impact of detergent treatment of live cells on the detection of PrV replication. PrV-infected HeLa cells were treated with detergents with varying biochemical characteristics and the impact of these treatments on the detection of PrV replication were evaluated. We observed that linear and non-ionic detergents, namely NP-40 and Triton X-100, were most effective at enhancing the detection of viral replication in PrV-infected HeLa cells. Our data confirm that detergent treatment results in enhanced detection, and not enhanced PrV replication, in HeLa cells. Using the stable BirA-p40 expressing HeLa cell line, we showed that the protein is associated with membranes in vitro, and that the enhanced expression of BirA-p40 results in the formation of greater volumes of detergent-resistant membranes. In addition, detergent treatment of unfixed PrV-infected HeLa cells revealed the presence of the PrV p40 protein in the nucleoli of the cells. This is the first report of PrV proteins, which are translated in the cytosol of the mammalian cells, occurring in the nucleus. Our study has resulted in a deeper understanding of PrV replication in mammalian cell lines. A ‘simple RNA virus’ with only three predicted open reading frames has exhibited high levels of complexity within its elegant simplicity. This study has also highlighted the challenges associated with studying RNA virus replication biology in vitro. Looking forward, the identification of detergent-based enhancement for the detection of PrV replication provides the opportunity to perform more targeted PrV replication studies. The PrV-based model system can also be applied to the identification and analysis of potential broad-spectrum antiviral drugs in vitro. The latter application is particularly relevant considering the increase in the number of viral outbreaks over the last decade.

- Description: Appraisal of African languages’ children’s literature and its translation seems to be developing at a slow pace. This literary genre seems to be the last on the literary critics’ list. As a result, children’s literature translators seem to do as they please, with no fear that there is someone to critique the work. Translation for children is more than just literary translation, because it is meant for a special audience, whose language skills are still developing. The translator, therefore, needs to be someone dedicated in target language development. This translation needs a translator with a deep knowledge of both the source and target languages and their cultures. This will result in a translation that is readable and acceptable in the target language. The aim of this study was to critically analyse 20 selected isiXhosa translated stories, looking at how they have been translated in order to sound original in the target language. A sample of five stories were taken and analysed looking at their macrostructure. The findings of the analysis were that the isiXhosa stories resembled the English ones. Even the equivalence of the translated versions showed that the translation transferred the message in the source texts. However there were challenges as indicated. The study was done using Skopos theory, which advocates for the translator to always keep their audience in mind. It suggests that the translator should always strive for a translation that is acceptable to the target language. Various strategies can be used by the translator to fulfil this. Some of the strategies found to have been used in the translations are adaptation through omission, addition, addition of target culture specific terms, and changing sentence mode. Generally, the source language message seems to have been successfully transferred to the target language. However, errors in some stories were a cause for concern, as they could deter the target reader’s interest in the stories. Such errors are spelling mistakes, word division errors, incorrect concord use, etc. These errors are a matter of concern in literature, more especially children’s literature where children are still developing their reading skills.

- Description: Olu phando lujolise ekubhentsiseni nasekuphononongeni nzulu indima yamasiko nezithethe kwiincwadi ezichongiweyo zesiXhosa ezizezi, “Ityala Lamawele” (1914) ibhalwe nguSamuel Edward Krune Mqhayi kunye no “Ukuba Ndandazile” (1967) ibhalwe nguWitness Kholekile Tamsanqa. Amasiko nezithethe aya kuthi aphononongwe ngala: ukulobola, ingqithi nesithembu. Kwakhona, la masiko nezi zithethe ziya kuthi ziphicothwe kugudlwa kwizinto zesiNtu ezinobuzaza eziqhushekwe zaze zancathama phantsi kwawo. Umzekelo, phantsi kwesiko lokulobola kukho izithethe ezithiwe qhushe phantsi kwalo ezifana nokuhota, ukuyalwa komtshakazi nezinye. Zonke ezi zinto ziya kuthi zivelelwe. La masiko nezi zithethe zichongwe kuba kukholeleka into ethi zitshatshele ngokwendima eziyidlalayo kwezi ncwadi zimbini. Ukubalasela kwawo la masiko nezithethe akwaneli ekubeni indima yawo ityhilwe kwezi ncwadi kuphela, koko indima yawo ithi ityhile banzi ngentlalo kaXhosa. Lilonke, aba babhali babini ababhali ngezinto ezingaziwayo okanye ezibuntsomirha, koko babhala ngemiba echaphazela amaXhosa ngqo. Umphandi uya kuthi aqhaqhe iindlela la masiko nezithethe aqhutywa ngazo, iinjongo zokwenziwa kwawo kwakunye neziphumo xa ethe la masiko enziwa okanye angenziwa ngokusesikweni. Konke oku kuya kuthi kwenziwe egameni lobuXhosa bemveli. Umphandi uya kukwenza oku ngeenjongo zokuphicotha nzulu intsingiselo ngokwamasiko nezithethe zamaXhosa ezama ukutyhila obona bunyani bufihlakeleyo bamasiko nezithethe kunye nokuzalana kwawo nentlalo yamaXhosa. Ngaphezulu, kukutyhila into ethi kwaXhosa amasiko nezithethe ziintsika zokuphila, ngako oko ananto ithile ayithethayo kuthi thina maXhosa ungaphiki nje kuba ezakwaLizwi zidungadungile ngendlela yazo kumzi kaPhalo ze zasahlukanisa nezinto zoobawo bethu. Kunamhlanje nje azinqabanga iintetho ezithi ukunqula iminyanya nezinyanya bubuhedeni, ukuxhela ibhokhwe kuyongxengxezwa bubudimoni. Kule ngxoxo, kuya kujongwa isakhono nobuchule bababhali abathe babusebenzisa njengesixhobo sokukhusela inkcubeko yamaXhosa eyathi yabhunyulwa ngamaNgesi yasala nje ibhityile, yiyo ke ngoku le esele igululwa okwamathumbu ngurhulumente wenkululeko. Lilonke, kwa kolu phando kunconywa ababhali abaziingcungela ekubeni basebenzise ulwazi lwabo lolwimi ekukhuseleni inkcubeko yamaXhosa athi xa ahlomla ngayo uMkonto (2005: v) athi: The study of the survival of cultural traditional customs in isiXhosa literature is an overdue task facing literary critics. Le ngcali ingentla apha ihlaba ikhwelo kubaphandi besiXhosa ukuba banyathelele phezulu bephanda bebhentsisa ubunyani bamasiko nezithethe kuncwadi lwesiXhosa. Olu phando, ngaphezu kwazo zonke izizathu, lusabela elo khwelo. Kwelinye icala, uthi uSaule (1996) xa ethetha ngoMqhayi, nangona uMqhayi lo wayenobuhlobo nabefundisi bezakwaLizwi nokhanyo kodwa akazange ayivumele ingqondo nentliziyo yakhe ithwetyulwe ziinkolo neenkcubeko zasemzini. Ukutsho ngokwakhe oku uSaule (1996: 20) xa ahambisa enjenje: Although Mqhayi was obviously a brain child of the missionaries, he did not, unlike many writers at that time, allow their influence to engulf his thoughts. He uses a Bible as a technique rather than as an instrument that guides him towards predestined objectives. Le ngcinga kaSaule ingentla igxininisiwe kwilixa elingaphambili nguDikeni (1992: 12) xa wayesithi: It is clear that Mqhayi as one of the early writers could not address the political situation of the South Africa directly in his novel. He had to use an extended metaphor to avoid the strict laws of censorship. This he did by using a Biblical story and adapting it to his culture. Ngokwezi ngcali zimbini, kuyaqapheleka ukuba nangona uMqhayi lo ifuthe laseNtshona lazama kangangoko linako ukumthwebula kodwa ukuhlakanipha kwakhe kwamenza wagwencela okwesikhwenene kwiingcambu zakhe, kwisizwe sakhe, kumasiko nezithethe zakwaXhosa. Kungani ke ukuba singangamphakamiseli phezulu lo mbhali ngokuthi simane sindwendwela iimbalo zakhe sihlaba sikhangela ukuba zithetha ukuthini na kuthi sizwe sikaXhosa xa sikule ndawo sikuyo nje? Kwelinye icala, uMkonto (2005) umqhwabela izandla uTamsanqa xa athi nangona wayefundile akazange ayivumele imfundo imntywilisele eludakeni lwaseNtshona hleze buthi obu buncwane bezi ncwadi zakhe zifana no “Buzani Kubawo” (1958), “Ukuba Ndandazile” (1967), “Imitha Yelanga” (1967) kunye nezinye zaziya kufela engqondweni yakhe engakhange afundise umzi kaXhosa ngobuXhosa bawo. UMkonto (2005: 17) uhambisa athi xa ethetha ngoTamsanqa: Most of his experiences which he shared with people at the time were of hardships ... probably these were some of the experiences that triggered the themes expressed in ‘Buzani kubawo’ and ‘Ukuba ndandazile’ Ngokwala mazwi angentla, okona kuncomekayo ngoTamsanqa kukuba uthe nokuba sele ehlangabezana neenzingo zobomi kodwa wabona kukuhle ukuba afundise umzi kaXhosa ngaloo mahla ndinyuka kuba kakade lisiko kwaXhosa into yokuba xa uye wagileka endaweni ethile uze ufundise abanye ukwenzela ukuba bangangeni kulaa mgibe ubuwele kuwo. Bubuntu ke obo. Ubukhulu becala bezinto athe wadlula kuzo uTamsanqa zicazululwe kwisahluko sesibini esidandalazisa ubunzululwazi mlando mbali wobom ngababhali. Okunye, uTamsanqa sesinye sezizukulwana esathi saneTamsanqa lokukhula ngeliya xesha amasiko nezithethe kwaXhosa bezisaqhutywa ngendlela encomekayo kunangoku, kodwa umfundi makaqaphele ukuba umphandi akazami kuthelekisa amaxesha amasiko nezithethe ezaziqhutywa kodwa ubona kubalulekile ukuba icace inkolelo ethi amasiko nezithethe namaxesha awayeqhutywa ngawo awasafani. Kolu phando nzulu okunye okuphambili kukuthi nangona aba babhali babini bathi basebenzisa ulwimi oluntsokothileyo nezagwelo zokubhala ezifihlakeleyo ngendlela enomkhitha kodwa loo nto ibe lulutho kumzi kaPhalo kuba ushiyeke ufumbethe ulwimi lwesiXhosa. Ngaphezu koko amaXhosa ashiyeke efumbethe ulwazi ngamasiko nezithethe ekusafuneka efundisiwe. Ingcambu yolu phando ke ingamasiko nezithethe kusetyenziswa isiThako samaSiko neziThethe esiza kuchazwa banzi kwimihlathi engezantsi. Ngaphandle kokuphonononga nzulu intsingiselo yamasiko nezithethe, olu phando lukwayinkuthazo kwabanye ababhali ukuba bazeke mzekweni benjenjeya ukuzalisa umphanda kaXhosa ngamasiko nezithethe kunye nolwimi olusulungekileyo khona ukuze izizukulwana ngezizukulwana zibe nento yokufunda. Ukongeza, kukukhuthaza abo babhali baneembalo ezintlakekileyo nezibutenxarha ngokwamasiko nezithethe, nolwimi ke, ukuba baziqhelanise nokufunda iincwadi zesiXhosa, bafunde isiXhosa, baphande ngokuzinikela ngemiba yesiXhosa. Njengamntu mtsha, olu phando lukhuthaza olunye ulutsha ngokubaluleka kokulondolozwa kwenkcubeko ukuze isizukulwana esizayo sibe nokufunda kuyo. Uphando olu lujolise ekukhuliseni iimbalo zesiXhosa ingakumbi ke xa sele lubhalwe ngesiXhosa. Likho iqaqobana elibhalileyo ngesiXhosa kodwa ezinye zezo mbalo ziyakhwinisa ngenxa yegrama etenxileyo, umgangatho ophantsi wokusetyenziswa kolwimi ukunonga iintetho, nezinye iziphene. Masibe sisithi ziinzame ekukhucululeni nasekuphuculeni oko kwenziwa ngabeLungu; masingaligxeki kakhulu elo gcuntswana. Enye yezinto ezikhwinisayo kuluncwadi lwesiXhosa kukunqongophala kweencwadi ezibonisa isiNtu sethu ngendlela egqibeleleyo nemsulwa. Iyathuthumba into yokunqongophala kweencwadi ezingembali yethu ebhalwe sithi. Oku kunqongophala kufika kube negalelo elibi kubafundi neetitshala zesiXhosa ezona kufuneka zingcamle ubuncwane benkcubeko yazo kunye nabafundi jikelele. Iincwadi eziya kuthi zisetyenziswe zezo zababhali abaziinjojeli kubhalo lwesiXhosa, uS.E.K. Mqhayi noW.K. Tamsanqa. Isizathu soko asikokuba umphandi uzama ukuthelekisa ababhali koko uya kubachonga, okokuqala, ngenxa yokuba bengababhali abaphume izandla kuncwadi lwesiXhosa. Okwesibini, kunconywa ubuchule babo ekusebenziseni ulwimi nesakhono njengesixhobo sokuphakamisa umgangatho woncwadi lwesiNtu ngokuyeleleneyo namasikonezithethe. Okwesithathu, iimbalo zabo zezinye zeembalo ezithe zaphakanyiswa kakhulungabaphandi de zafumana amawonga ngamawonga. Okwesine, kudederhu lweencwadizesiXhosa ezingaka andinokwazi ukuthi ndilume umthamo omkhulu endizojika ndixakane nawo ndingakwazi ukuwuhlafuna ndiwucokisise hleze ndomiwe emqaleni ndingabisalugqiba kwa olo phando.

Kwelinye icala, uMkonto (2005) umqhwabela izandla uTamsanqa xa athi nangona wayefundile akazange ayivumele imfundo imntywilisele eludakeni lwaseNtshona hleze buthi obu buncwane bezi ncwadi zakhe zifana no “Buzani Kubawo” (1958), “Ukuba Ndandazile” (1967), “Imitha Yelanga” (1967) kunye nezinye zaziya kufela engqondweni yakhe engakhange afundise umzi kaXhosa ngobuXhosa bawo. UMkonto (2005: 17) uhambisa athi xa ethetha ngoTamsanqa: Most of his experiences which he shared with people at the time were of hardships ... probably these were some of the experiences that triggered the themes expressed in ‘Buzani kubawo’ and ‘Ukuba ndandazile’ Ngokwala mazwi angentla, okona kuncomekayo ngoTamsanqa kukuba uthe nokuba sele ehlangabezana neenzingo zobomi kodwa wabona kukuhle ukuba afundise umzi kaXhosa ngaloo mahla ndinyuka kuba kakade lisiko kwaXhosa into yokuba xa uye wagileka endaweni ethile uze ufundise abanye ukwenzela ukuba bangangeni kulaa mgibe ubuwele kuwo. Bubuntu ke obo. Ubukhulu becala bezinto athe wadlula kuzo uTamsanqa zicazululwe kwisahluko sesibini esidandalazisa ubunzululwazi mlando mbali wobom ngababhali. Okunye, uTamsanqa sesinye sezizukulwana esathi saneTamsanqa lokukhula ngeliya xesha amasiko nezithethe kwaXhosa bezisaqhutywa ngendlela encomekayo kunangoku, kodwa umfundi makaqaphele ukuba umphandi akazami kuthelekisa amaxesha amasiko nezithethe ezaziqhutywa kodwa ubona kubalulekile ukuba icace inkolelo ethi amasiko nezithethe namaxesha awayeqhutywa ngawo awasafani. Kolu phando nzulu okunye okuphambili kukuthi nangona aba babhali babini bathi basebenzisa ulwimi oluntsokothileyo nezagwelo zokubhala ezifihlakeleyo ngendlela enomkhitha kodwa loo nto ibe lulutho kumzi kaPhalo kuba ushiyeke ufumbethe ulwimi lwesiXhosa. Ngaphezu koko amaXhosa ashiyeke efumbethe ulwazi ngamasiko nezithethe ekusafuneka efundisiwe. Ingcambu yolu phando ke ingamasiko nezithethe kusetyenziswa isiThako samaSiko neziThethe esiza kuchazwa banzi kwimihlathi engezantsi. Ngaphandle kokuphonononga nzulu intsingiselo yamasiko nezithethe, olu phando lukwayinkuthazo kwabanye ababhali ukuba bazeke mzekweni benjenjeya ukuzalisa umphanda kaXhosa ngamasiko nezithethe kunye nolwimi olusulungekileyo khona ukuze izizukulwana ngezizukulwana zibe nento yokufunda. Ukongeza, kukukhuthaza abo babhali baneembalo ezintlakekileyo nezibutenxarha ngokwamasiko nezithethe, nolwimi ke, ukuba baziqhelanise nokufunda iincwadi zesiXhosa, bafunde isiXhosa, baphande ngokuzinikela ngemiba yesiXhosa. Njengamntu mtsha, olu phando lukhuthaza olunye ulutsha ngokubaluleka kokulondolozwa kwenkcubeko ukuze isizukulwana esizayo sibe nokufunda kuyo. Uphando olu lujolise ekukhuliseni iimbalo zesiXhosa ingakumbi ke xa sele lubhalwe ngesiXhosa. Likho iqaqobana elibhalileyo ngesiXhosa kodwa ezinye zezo mbalo ziyakhwinisa ngenxa yegrama etenxileyo, umgangatho ophantsi wokusetyenziswa kolwimi ukunonga iintetho, nezinye iziphene. Masibe sisithi ziinzame ekukhucululeni nasekuphuculeni oko kwenziwa ngabeLungu; masingaligxeki kakhulu elo gcuntswana. Enye yezinto ezikhwinisayo kuluncwadi lwesiXhosa kukunqongophala kweencwadi ezibonisa isiNtu sethu ngendlela egqibeleleyo nemsulwa. Iyathuthumba into yokunqongophala kweencwadi ezingembali yethu ebhalwe sithi. Oku kunqongophala kufika kube negalelo elibi kubafundi neetitshala zesiXhosa ezona kufuneka zingcamle ubuncwane benkcubeko yazo kunye nabafundi jikelele. Iincwadi eziya kuthi zisetyenziswe zezo zababhali abaziinjojeli kubhalo lwesiXhosa, uS.E.K. Mqhayi noW.K. Tamsanqa. Isizathu soko asikokuba umphandi uzama ukuthelekisa ababhali koko uya kubachonga, okokuqala, ngenxa yokuba bengababhali abaphume izandla kuncwadi lwesiXhosa. Okwesibini, kunconywa ubuchule babo ekusebenziseni ulwimi nesakhono njengesixhobo sokuphakamisa umgangatho woncwadi lwesiNtu ngokuyeleleneyo namasikonezithethe. Okwesithathu, iimbalo zabo zezinye zeembalo ezithe zaphakanyiswa kakhulungabaphandi de zafumana amawonga ngamawonga. Okwesine, kudederhu lweencwadizesiXhosa ezingaka andinokwazi ukuthi ndilume umthamo omkhulu endizojika ndixakane nawo ndingakwazi ukuwuhlafuna ndiwucokisise hleze ndomiwe emqaleni ndingabisalugqiba kwa olo phando.

- Description: The southeast coast of Madagascar, namely the region surrounding the town of Fort Dauphin, is an area that regularly experiences upwelling events. Two unique high frequency data sets, UTR data, and wind data retrieved from a nearby airport, are the primary data sets used to investigate the nature of the upwelling, i.e. the area that experiences upwelling, how often it occurs, and its mechanisms. To complement the in-situ data, several different satellite data sources are used alongside the in-situ data to study this relatively remote region, i.e. SST, chlorophyll-a concentration, current, and wind data. The results refine upon previous literature on the topic. The upwelling covers an area of 1o latitude by 1.3o longitude, and occurs on average 14 times per annum. The mechanism driving the upwelling can be attributed to both wind and current, with wind the more dominant driver along the south coast, and current more dominant along the east coast. Separate to the main objective of the thesis is the importance of in-situ data when analysing small scale events such as upwelling events. While the in-situ wind data were found to be unreliable due to its location within a valley, the UTR data were of vital importance in identifying and studying the finer details of the upwelling events. The satellite SST data, by comparison, were lacking in their ability to investigate the upwelling events. The satellite derived wind data, however, did prove useful when analysing the wind as a driver of the upwelling.

- Description: Over the past several decades, the world’s population has been rapidly urbanising, which has resulted in a marked shift of global population from rural to urban areas. About half of the global population now reside in urban areas and is projected to increase to two-thirds by the year 2050. However, the majority of the future urban population growth is projected to be largely concentrated in Asia and sub-Saharan Africa. Despite the economic prospects normally synonymous with urbanisation, the current speed and scale of urban transformation comes with formidable challenges to contemporary urban society in these two continents. Urbanisation may presents social, economic, health and environmental challenges in urban areas, not least being a shift of the locus of food insecurity from rural to urban areas, leading to poor dietary diversity among many urban dwellers. Similarly, urbanisation alters key ecosystem services and drives habitat alteration and fragmentation, biodiversity loss, proliferation of non-native species and changes on species diversity and richness. The aforementioned changes can result in a deterioration of living conditions and decline on the quality of life for the urban dwellers. However, on the other hand, urban green infrastructure is posed as vital tool in promoting liveable cities and enhancing livelihood resilience. Against this backdrop, this study portrays wild plants, a component of urban green infrastructure, as a key resource in promoting food security and dietary diversity, thereby promoting livelihood resilience and reduced vulnerability, especially of the urban poor. Framed under the ‘right to the city’ approach, this study examined urban foraging practices and their potential contribution to dietary diversity and how they are shaped by and respond to urbanisation in two medium-sized South African towns. The study was conducted in the towns of Potchefstroom and Thabazimbi, South Africa. An explanatory sequential mixed method design was employed for data collection. Multi-stage sampling was employed in selecting the study participants. Firstly, the study towns were stratified into four socio-economic zones: informal, reconstruction and development programme, township and affluent. These zones resemble high density (informal, reconstruction and development programme), medium density (township) and low density (affluent) areas. Then, a total of 374 households were randomly sampled across the socio-economic zones for the main survey (Chapter 3 and 5). A subset of this sample, i.e. 72 participants was considered for dietary recalls, alongside with a random sample of 65 non-foragers (Chapter 4). An inventory of plant species available in a given foraging space was conducted from a total of 136 plots spread across different urban spaces (Chapter 2). Semi-structured interviews were conducted with a total of 81 participants (sub population of the main survey) for elucidating data on urban dynamics (Chapter 6). Lastly, complementary in-depth interviews with 46 participants were conducted. The findings showed that different urban spaces were constituted by diverse vegetation, with 262 distinct plant species encountered across the spaces. The majority (60.7%) were indigenous to South Africa. Species composition and diversity varied with space type, being significantly high in protected areas as compared to the other space types. About half (53%) of the identified plant species had at least one documented use, with medicine, food and firewood being modal, in order of frequency. Species composition and diversity differed between forageable and non-forageable species, being significantly high for forageable species. Urban foraging was widespread, about 68% of the respondents reported foraging. Foraging provided food, fuel energy, medicine, and cultural affirmation, among others. Despite the high prevalence rate of foraging, the study did not find any meaningful contribution of wild foods to overall diets. Nonetheless, wild foods demonstrated a substantial contribution in diversifying diets within particular food groups consumed such as vegetables, thus emerging essential in mitigating monotonous urban diets, particularly of the urban poor. Besides, the prevalence of foraging differed significantly between and within towns, being high for Thabazimbi (54.7%) and residents in the outskirts of town (86.2%) than Potchefstroom (45.3%) and residents in the inner part of town (33.3%). Participation in foraging was primarily a function of childhood (91.8%) exposure and experience with foraging, positive perceptions (79%) towards practice, resident in the outskirts of town (86.2%) and low household income (49.2%). The findings indicated that foraging was driven by multifaceted motivations, with culture (91.8%), health (88.7%), livelihoods needs (75.0%) and leisure (73.8%) being the most common. Vacant spaces (54.7%), riparian areas (30%), and domestic gardens (17.9%) were the most preferred foraging spaces, albeit with differences within towns. Similarly, the mean frequency of access varied with foraging spaces, being slightly high for vacant spaces than riparian areas and domestic gardens. The majority of the respondents were unaware of both formal and informal regulations managing urban landscapes, with those acknowledging some awareness falling short of articulating on the specificities of the regulations. Besides, the findings showed that foraging practice was threatened by urban transformation. Foragers perceived that the practice has changed over time, in terms of spaces, participants and regulations. There was a decreasing trend on the number and size of foraging spaces as well as shifting demographic trends of foragers. Moreover, urban transformation brought about a new set of regulations used for managing certain spaces within the urban landscape. However, some regulations prohibited or restricted access and rights to certain spaces for foraging. Hence, this prompted foragers to devise adaptation strategies to cope with the said changing dynamics. Exploring new foraging sites within and outside forager’s neighbourhoods and negotiating access entry were the most frequently mentioned adaptation strategies. This study contributes to the emerging body of knowledge on urban foraging, which has being seldom understood in the Global South.

- Description: Recent socioecological approaches in Environmental Education acknowledge the complexity of “real-world situations”, which include environmental problems. One response to the challenge of enabling people to develop sustainability is the key competencies in sustainability framework. It can be faced as a guide to planning Environmental Education actions. On the other side, art practices hold potential to expand learning in varied ways. Art can offer the strategies employed in learning processes directed to sustainability, constituting the field of eco-art education. This research aims to investigate the integration of the visions of the key competencies in sustainability and the eco-art education in an Environmental Education project at high school level. Horta and Gastronomia (Vegetable Garden and Gastronomy) is an extra-curricular activity which happens every year at Irmão Jaime Biazus high school in Porto Alegre, Brazil. It addresses food security and sustainability associating the garden, the kitchen and exploration of sustainability issues using eco-art strategies. Action research approach is used, defining two research cycles to explore the effectiveness of eco-art for the development of key competencies in sustainability. The first cycle focuses on the eco-art activities applied in Horta and Gastronomia (2017 group) while the second cycle deals with a post-project intervention designed to observe indicators of the sustainability competencies and further explore eco-art strategies. This study adds to the field of sustainability competencies by exploring teaching strategies through eco-art education. Insight into key competencies in sustainability is given by presenting the investigation of the group of students about a situation of their reality. The activities implemented, classified according to their objectives, are contextualized regarding the competencies and in learning sequences. This research also contributes to the development of the sustainability competencies framework by applying the theory to a basic education level, adapting the work originally proposed to higher education contexts.

- Description: In marine protected areas (MPAs), the radically open nature of marine ecosystems, the seemingly contradictory short-term goals of fisheries management (resource use) and conservation efforts (biodiversity protection), the variety of stakeholders, and the inherently political nature of space ha ve contributed to a disconnect between policy and practice. Many groups operate in an MPA at various spatial and socio-political scales, from national government bodies to local community groups, as such an MPA can be viewed as a complex, multi-scale and multi-level social-ecological system (SES). A greater understanding of the multi-scale processes driving the spatial resilience of SES can help address scale mismatches between continuous ecological change and the long-term governance of a seascape. South Africa has a long history of spaces and natural resources being politicised and faces high levels of unemployment and political frustration. Marine governance has been characterised as being siloed, lacking transparency regarding government processes and even between departments, and not properly addressing the needs of local communities; resulting in scale and level mismatches throughout the multi-scale processes (from national policies to local regulations)therefore, it is pertinent to understand the interactions between various national policies, their implementation, and their impacts. Using a spatial resilience lens, I set out to understand scale alignment in South Africa’s marine governance systems as it relates to MPAs. A spatial resilience lens emphasises analysis of both spatial and temporal scales, thus highlighting the multi-scale variables and interactions that occur within a system. I first sought to understand the policy and management across national and regional scales by conducting a series of semi-structured interviews with experts which were analysed using thematic analysis. I then approached the question of alignment from a local to national scale by using the Table Mountain National Park Marine Protected Area as a case study, here I carried out a series of workshops and interviews with line fishers, women’s groups, and eco-tourism operators from three different communities. Experts identified six themes when describing the structure of gove rnance in South African MPAs; they consisted of: government departments and marine legislation, management level factors, communication and information sharing, local level factors, biophysical factors, and scale. Communication and information sharing was the most mentioned referenced theme (40.26 %). The relationships between the communities and other actors (i.e. how communities are impacted, or impact on, the Department of Environmental Affairs , the Department of Agriculture Forestry and Fisheries, and Park Authorities) contributed 67.27 % to the total number of mentions, 91 % of which were from the following themes: communication and information sharing, local level factors, biophysical factors, and scale. My results indicate that weak, top-down relationships dominate the governance system in South Africa. During the Cape Town workshops I applied the spatial resilience lens in three ways. Firstly, the participants collaborated on a mapping exercise discussing the existing zone types within the MPA, as well as developing their own. There was an 87.87 % overlap of community designed zones on the existing MPA zones, however the types of zones designed by the community were different. Secondly, I carried out a document analysis and used information from the workshops to analyse the status and rights designation of important species for different user groups. The results show that the various stakeholder groups, while all active in the marine environment, interact with the ecosystem at different scales and with differing species. The differing interactions between groups result in challenges such as representation and complicated power dynamics between user groups. Finally, I asked participants to discuss factors that affect their ability to gain a livelihood from the sea. The external elements and their effects differed between the user groups, identifying important socio-political interactions. Whilst the external elements were all geographically distinct and localised, the spatial resilience lens allowed for a cross-scale, and to a certain extent cross-sector, understanding of these elements thus producing a more holistic understanding. My thesis shows that user groups operate on different spatial scales within the marine environment as a result of social, economic, and political influences leading to several scale-based challenges. The identified scale-based challenges have contributed to misalignments in marine governance in South Africa. My study shows that scale mismatches have important implications for understanding how marine policy influences user groups and identified pathways that affected policy implementation , and identifies future research application of a spatial resilience lens within social-ecological systems, for example it’s potential use in understanding the gendered nature of MPAs

I then approached the question of alignment from a local to national scale by using the Table Mountain National Park Marine Protected Area as a case study, here I carried out a series of workshops and interviews with line fishers, women’s groups, and eco-tourism operators from three different communities. Experts identified six themes when describing the structure of gove rnance in South African MPAs; they consisted of: government departments and marine legislation, management level factors, communication and information sharing, local level factors, biophysical factors, and scale. Communication and information sharing was the most mentioned referenced theme (40.26 %). The relationships between the communities and other actors (i.e. how communities are impacted, or impact on, the Department of Environmental Affairs , the Department of Agriculture Forestry and Fisheries, and Park Authorities) contributed 67.27 % to the total number of mentions, 91 % of which were from the following themes: communication and information sharing, local level factors, biophysical factors, and scale. My results indicate that weak, top-down relationships dominate the governance system in South Africa. During the Cape Town workshops I applied the spatial resilience lens in three ways. Firstly, the participants collaborated on a mapping exercise discussing the existing zone types within the MPA, as well as developing their own. There was an 87.87 % overlap of community designed zones on the existing MPA zones, however the types of zones designed by the community were different. Secondly, I carried out a document analysis and used information from the workshops to analyse the status and rights designation of important species for different user groups. The results show that the various stakeholder groups, while all active in the marine environment, interact with the ecosystem at different scales and with differing species. The differing interactions between groups result in challenges such as representation and complicated power dynamics between user groups. Finally, I asked participants to discuss factors that affect their ability to gain a livelihood from the sea. The external elements and their effects differed between the user groups, identifying important socio-political interactions. Whilst the external elements were all geographically distinct and localised, the spatial resilience lens allowed for a cross-scale, and to a certain extent cross-sector, understanding of these elements thus producing a more holistic understanding. My thesis shows that user groups operate on different spatial scales within the marine environment as a result of social, economic, and political influences leading to several scale-based challenges. The identified scale-based challenges have contributed to misalignments in marine governance in South Africa. My study shows that scale mismatches have important implications for understanding how marine policy influences user groups and identified pathways that affected policy implementation , and identifies future research application of a spatial resilience lens within social-ecological systems, for example it’s potential use in understanding the gendered nature of MPAs

- Description: Background: Young women in South Africa are a vulnerable group, with HIV prevalence almost twice that of men, limited preventive behaviour, and many challenges in negotiating sex. However, there is a paucity of in-depth research to understand how these challenges play out and what can be done to promote positive sexual and reproductive health in this population. Methods: To understand the effects of the Auntie Stella Activity card intervention (developed and used in Zimbabwe), this study used a mixed methods participatory action research design. Five focus group discussions among female Rhodes University students between the ages of 18- 23 were conducted with the activity cards as a basis for engagement. Additionally, pre-and postintervention sexual and reproductive health awareness levels were also measured by a customized questionnaire. Based on participants’ responses to the cards and post-exposure reflections on their learning, possible impacts on behaviour change were explored. Thematic analysis of transcripts was used to draw out major themes in the qualitative data. Results and conclusions: Themes that emerged were: 1) women’s self-esteem; 2) lack of knowledge; 3) peer pressure and male dominance; and 4) alcohol and substance use. Results of the pre- and post- intervention questionnaire found a positive change in knowledge and behaviour amongst the participants. However, the intervention in its current format focused too much on teenage rather than adult scenarios. To make it more useful for this population, further modifications that account for the target age group are needed. Overall, the challenges in sexual and reproductive health faced by university-aged women in South Africa are deeply concerning, but this study’s findings show that an intervention like the ASAC has the potential to be used widely in Southern Africa, if appropriately tailored.

- Description: The visually impaired do not have the visual ability to localize objects in three-dimensional space, rather, they rely on their other senses to gain depth perception. Sensory substitution is the concept of substituting one sense for another, normally substituting an impaired sense with a functioning sense. Visual-to-auditory sensory substitution substitutes an impaired visual sense with a functioning auditory sense. This research aimed to investigate and develop techniques for visualto-auditory sensory substitution – using sound localization as a sensory substitution for depth perception. The research started by investigating the characteristics of human audition with a particular focus on how humans localize sounds. It then looked at existing visual-to-auditory sensory substitution systems and the techniques they used. From the existing systems, a system known as MeloSee was chosen as a baseline for developing and evaluating further sensory substitution prototypes. The baseline prototype (𝑃0) was then implemented and a preliminary study performed. Based on the knowledge gained from the preliminary study, baseline implementation and the background research, a set of improvement recommendations were generated. The next iteration – Prototype 1 (𝑃1) – was then developed based on the recommendations. A comparative study between 𝑃0 and 𝑃1 was then performed. Based on the study, another set of improvement recommendations were generated. From the recommendations, a final prototype was developed – Prototype 2 (𝑃2). The last comparative study was then performed between 𝑃0 and 𝑃2, with a third set of recommendations being generated as a result. From the studies it was found that participants using 𝑃0 were able to identify when they were approaching large objects such as walls. 𝑃1 built on that, improving the ability to identify the quadrant of a nearby isolated object. 𝑃2 built on 𝑃0 and 𝑃1, achieving similar results to 𝑃1 for identifying the quadrant of nearby isolated objects, and improving on 𝑃0 and 𝑃1 with regard to depth discrimination – especially for navigation tasks where there were no obstacles. Based on the three sets of recommendations and what was learnt over the course of the research, a set of visual-to-auditory sensory substitution techniques were presented. The techniques aim to be useful for implementing visual-to-auditory sensory substitution systems, which would provide the visually impaired with the visual ability to localize objects in three-dimensional space through sound.

- Description: Despite the vast research on African poetry by scholars like Qangule (1979), Ntuli (1984), Sirayi (1985), Bokoda (1994), Mtumane (2000), Bobelo (2008) and Jadezweni (2013), there is a paucity of extended research on the aesthetic works of African poets in South Africa in the post-apartheid era. In a quest to redress this imbalance, I undertook a comparative study of two prominent African poets in the post-apartheid era in South Africa. This study adds nuance to our understanding of African poetry as it would define African poetry further from an African perspective. Swanepoel (1990) challenges scholars of African literature to have a critical look on the developments of neighbouring literatures as comparing these literatures produces new and useful ideas about African literature. In addition, scholars such as Gerard (1981) and Perera (1991) advocate for the creation and adoption of a comparative methodology for the study of African literature. This led scholars such as Mdaka (2002) to test comparative methodology in assessing ideology and aesthetics in South African isiXhosa novels and Kenyan novels written in English. Likewise, Cutalele (2007) uses comparative methodology in investigating similar themes in the aesthetics works of S.E.K. Mqhayi and Zolani Mkiva. In responding to Swanepoel’s challenge, this study aims to investigate and evaluate the importance of the voice of imbongi in articulating current and burning issues in the post-apartheid South Africa as well as the solutions they propose to some of the problems facing the country. In this study, the methodology swings on the hinges of Ngara’s Marxist theory. The choice of Ngara’s Marxist theory is based largely on its theoretical insights on ideology, form and communication in analysing poetry. Ngara divides ideology into three sub-themes: dominant ideology, which refers to the beliefs, set of values, thoughts and actions of a people in a particular era, authorial ideology that refers to the set of values espoused by the poet and aesthetics ideology, which is the literary convention and stylistic of the poet. Using the comparative method, the voice of imbongi in Mbuli and Mkiva’s poetry is compared over three ideologies – protest, patriotism and revolution. Under the theme of protest, I compare Mkiva and Mbuli’s poetry under two sub-themes, socio-political protest and socio-cultural protest. Mbuli and Mkiva’s protest agitates for change in the political and cultural spheres of the post-apartheid South Africa. Page viii of 290 They comment on issues like leadership and social welfare of South Africans, burning issues of this era. In the theme of patriotism, I examined poetry that displays love and loyalty for one’s country. In displaying their love and loyalty for their country, it is clear that to Mbuli and Mkiva, country refers to Africa, not just South Africa. Furthermore, under the theme of revolution I examined poetry that praises struggle heroes as well as the one that introduces the new struggles of the people of South Africa. In praising revolutionary leaders, Mbuli and Mkiva parade good leadership skills for the new breed of leaders to learn. In discussing the revolutionary theme, they speak of economic freedom as one of the struggles of the new South Africa. In investigating and evaluating their poetry in post-aparthied South Africa, I discovered that in their protest and their revolutionary ideology they express the theme of disillusionment. They speak against corruption in leadership while they question those who violate children and women’s right to life. Such issues were thought to be buried with the death of apartheid. Furthermore, they introduce us to neo-revolution by showing how the struggle for freedom still continues as freedom without economic freedom falls short of freedom.

- Description: The construction industry demands active construction organisation, efficient construction processes and innovative construction techniques to effectively compete under increasing market competition and technological advancements in the twenty first century. The problems associated with construction, such as poor quality and slow productivity, labour shortages, occupational health and safety, and inferior working conditions, have opened the possibility of more revolutionary solutions within the industry. One such solution espoused as having tremendous potential to improve construction productivity whilst alleviating the problems associated with construction is Construction Automation and Robotics. Automation and robotics technologies encompass a wide range of innovative technologies using technologically advanced machinery to improve the speed and efficiency of a given process. The aim of this study is to analyse the extent of utility of construction automation and robotics in the South African construction industry. The research adopted the quantitative methodology and online survey to collect data. A detailed quantitative (statistical) data analysis was performed, using web-based software “QuestionPro,” including data analysis for investigating possible relationships between variables. Through this study it has been established that one of the prospective solutions to the problems associated with construction is in the implementation and utility of innovative technologies in construction such as automation and robotics. Moreover, the research found that automation and robotics in South Africa is at an interesting point whereby organisations are taking strides in accepting and implementing the technologies. It is envisaged that the utility of construction automation and robotics would improve the industry in terms of productivity, health and safety and quality.

- Description: With the revival and rapid growth of relations between China and African countries in the present century, the “China-Africa relationship” has become a topic of close attention globally and the media and politicians have been dominating the mainstream discourses with dichotomised narratives. China-Africa engagement has also spurred academic research, most of which is oriented toward large-scale economic, political, and strategic concerns. In this context, it is significant to conduct in-depth research exploring specific engagement between Chinese and African people on the ground. Contemporary artists based in Africa have started to represent, through artworks and performances, their experiences and expressions of relations between China and various African countries. However, an examination of twenty-first century connections between Africa and China in relation to the contemporary visual arts is a new area of study and only a limited number of scholarly works exist. To contribute to the research in this area, this thesis explores the ways in which artists engage with specific realities and lived-experiences of Chinese presence through their artistic practices, with a focus on a selection of artists from Zambia and Zimbabwe. Through visual analysis, interviews and field work, this thesis provides a systematic investigation of contemporary arts of Zambia and Zimbabwe in relation to Africa- China encounters, engaging with four aspects: the discursive field, the material presence, individual experiences of encounters, and the broader relational connections within the arts. This thesis argues that, motivated by the histories and realities of African societies, artists from Zambia and Zimbabwe, through their artistic practices, form part of the Africa-China engagement and insert their agencies in the south-south relations between Africans and Chinese. Therefore, this thesis demonstrates the value in approaching the broader discussion on Africa-China engagements from the perspective of contemporary art, arguing that, with the social concerns of the artists and the expressive capacity of creative forms, visual arts are able to embrace diversity, dynamics, complexities and contradictions, and, therefore, can develop the topic beyond the stereotypical narratives about Africa-China relations to a more nuanced understanding of African-Chinese encounters in specific contexts.

- Description: The field of Psychology is constantly shifting in its understanding of mental health. Scholars have been critiquing Psychology’s narrow perspective of what constitutes ‘normal’. Many dealing with mental health issues fear that they will be misunderstood and are confronted with systems and institutions that they find unempathetic. This mini-thesis conceptualises creative empathy as a solution to these problems. It is based on the idea that every experience is unique and therefore cannot be wholly understood without engaging in an imaginative process. The appropriateness of the comics medium as a tool for promoting this strategy is explored with a focus on the use of visual imagery to tell stories of distressing experiences. It looks at Tayla Shan Solomon’s The Adventures of Apparently-Anyone-Can-Do-It-If-TheyJust-Try Bug! (2019), Art Spiegelman’s Maus (I & II) (1986), Joe Kelly and JM Ken Niimura’s I Kill Giants (2011), and Allie Brosh’s Hyperbole and a Half: unfortunate situations, flawed coping mechanisms, mayhem, and other things that happened (2013). This mini-thesis analyses various techniques employed by comics artists to create compelling stories of idiosyncratic experiences, including the use of symbolic imagery and framing.

Furthermore, globally (the world) and locally (South Africa) the study of the experience of tertiary education institutions as walked environments is minimal (see Puig-Ribera et al., 2008; Speck et al., 2010; Mtolo, 2017). However, the events of the South African #MustFall moment – especially the #RhodesMustFall part of the moment and how it began with the desecration of a statue that was walked past and found to be a misplaced artefact in a society that is in postcolonial/post-Apartheid times and space – highlighted the pressing need to study the experience of the university as a place through which habitual walking takes the student through moments of movement, rest, and encounter that are a highly consequential way in which placeness is experienced. This study is a way to document how students at Rhodes University experience the university’s placeness quality, through habitual walking, in an example of the way in which a place is experienced through moments of movement, rest, and encounter. For this study in-depth mobile interviews were conducted with 12 student participants from Rhodes University. The interviews were video-recorded as the participants talked while traversing through habitually walked areas of the campus that are the meaning-infused spaces which make up the Rhodes University that they traverse through on a daily basis. The dissertation found that in the experience of Rhodes University, through habitually walking its placeness, people experience moments of movement, rest, and encounter that are highly targeted and personalised. The experience of the Rhodes University campus is an experience of people and the built-up and decorated environment along similar lines. People bring to the experience of their walked space past experiences which inform consequentially how any space that is walked is experienced. People further employ strategies to ensure that the experience of walking a space is more to their desired quality as an experience, which ends up being meaningful and most likely to affect future instances of walking through meaning-infusing and meaning-infused space. Ultimately, the habitual walking of Rhodes University consequentially informs the relationship between students and Rhodes University’s placeness, as the walking is a way of learning how to be within a placeness that is engaged through alternating moments of movement, rest, and encounter that incrementally ‘open’ for experience Rhodes University in such a targeted manner that every student eventually has their personal and customised Rhodes University by virtue of it being just those sites and situations which have been engaged through habitual walking.

- Description: This study focused on waste management, and, sought to evaluate the level of awareness on environmental impact of littering in vulnerable communities in the informal settlements of Msukaligwa municipality, in particular at Ward 16 which is Nyibe newly named as New Ermelo. This study was, thus, concerned with how solid waste is managed within the informal settlements. The study arose with the concern that the environment is mostly affected when informal settlements are developed. If informal settlements are less aware of the damage caused by littering and improper waste disposal, the waste management plan of a local municipality becomes ineffective where local communities do not assume their responsibilities for ensuring healthy and safe living environments. A quantitative research design was applied in this study. Population for this research comprised of Msukaligwa Local Municipality, with a study sample drawn from Ward 16 Nyibe households, church leaders, local business owners, and ward councillor. A nonprobability sampling technique for selection of study participants was used, and this technique applied in both households and stakeholders. Data was collected through self-administered survey questionnaires that were statistically analysed, weaving in filed observations, where deemed necessary. The researcher discovered that Nyibe (New Ermelo) community’s level of awareness of the environmental impact of littering is impressively above average. Majority of households’ respondents identified all the negative environmental impact caused by littering in vulnerable communities and the impact is considered a major challenge within Nyibe. Necessary waste disposal infrastructures are not provided at Nyibe leading to people littering on any open land, burning, or throwing solid waste in their family pit.

- Description: Forests and trees are important modulators of water flow and their position in the landscape impacts the spatial and temporal availability of ground water and surface water resources. As such, the global extent of natural forests is linked to the availability of water. In the circumstances where tree production systems have been introduced and are managed in landscapes previously populated with other forms of vegetation, it is necessary to understand their hydrological impact so as to ensure that the benefits derived from these tree systems do not outweigh the costs of water availability for sustaining human and environmental water requirements.

- Description: South Africa is a semi-arid, water scarce country. The nation has suffered a spate of severe droughts in several regions in recent years, which have significantly impacted the country’s economy. Global warming, population growth, and rising demand for water intensive products are only expected to intensify water supply problems in the future. The agricultural industry is the largest consumer of water in South Africa, accounting for the majority of total surface water withdrawals. As such, the agricultural sector is faced with complex and difficult management decisions in the face of a potential water supply crisis. The water footprint (WF) and economic water productivity (EWP) of citrus production across three river catchments located in the Eastern Cape Midlands (situated in the vicinity of the settlements of Adelaide, Cookhouse and Fort Beaufort respectively) were calculated and compared. In the long-term average (LTA), blue WF weighted across all three regions accounted for the greatest proportion of total WF (53%), followed in turn by green and grey WF (30% and 17% respectively). LTA blue and grey WF was lowest in the Adelaide region, while green WF was smallest in the Fort Beaufort region. Blue, green and grey WF were found to be greatest in the Cookhouse region. LTA EWP was greatest in the Fort Beaufort region and smallest in the Adelaide region. Of all variety groups assessed, lemons were found to have the lowest LTA crop water use and blue, green and grey WF when considering citrus production averaged across all three study regions. Satsumas has the second smallest LTA blue, green and grey WF, followed by navels, mid-season mandarins, and finally, late mandarins. Lemons had the greatest LTA EWP of all varieties, followed in turn by satsumas, late mandarins, mid-season mandarins and navels. Blue crop water use was consistently lowest in the designated wet year and highest in the dry year. However, this same trend was not necessarily true for WF findings. WF and EWP are useful indicators of water use which can be used to help guide complex water management decisions. However, these indicators are single-factor productivity measures applied in a multi-factor environment. It is therefore important that factors outside of water use are considered when making water management decisions. Moreover, it is important to examine the impact that the various components making up WF and EWP have on the resultant figures, rather than merely considering the superficial results themselves. Factors such as CWU, orchard maturity, crop choice, potential yield, climate, irrigation system, economic return, water allocation and water availability should all be taken into account.

- Description: This study examines how whiteness, particularly South African whiteness, is constructed in a propagandistic YouTube documentary entitled Farmlands and how these constructions are taken up and negotiated by its viewers in its associated comment section. I suggest that these constructions are not only racialised, but resuscitate and popularise old colonial discourses that perpetuate the fear of a ‘white genocide’ and the perceived extermination of a ‘pure white civilisation’. A thematic analysis informed by theories of representation, the establishment of difference through meaning, discourse and critical whiteness studies show that there are several narratives constructed through binary oppositions informed by colonial understandings of race, juxtaposing whiteness and blackness. In analysing these constructions, I aim to demonstrate that whiteness often becomes violent and defensive when its power is perceived to be under threat, reproducing itself through binary constructions that aim to protect it. In doing so, I demonstrate how whiteness is globalising from previous narrow nationalist framings to embracing a globalised notion of ‘white civilisation under threat’. This study supports research that is sceptical of the democratizing ability of the internet and social media, focusing specifically on YouTube’s comment forum and how it is utilized to mobilize attitudes based on hatred, racism and profound social exclusion.

- Description: As a writer and as an academic, I have long been interested in young black Africans. As a demographic group, we are heralded as the future of Africa and a vital resource, but not much is known about us, what we think, and how we make sense of things. As an African youth myself, I know that we are a diverse group with different backgrounds, perspectives and beliefs. I am interested in exploring our identities, how we express ourselves and how we make sense of ourselves, each other, the continent and the world. I want to learn more about how we see the world, and what we think of how media narratives and messages represent us. This research project is an extension of this personal curiosity. It focuses on Black Panther, a film that received particularly strong responses from young black Africans. I want to explore why this film in particular prompted such a strong reaction, and what the imagining of an uncolonised, technologically advanced African nation that Black Panther offers means for the young black Africans born after the official end of apartheid and colonisation.
