- Description: The main focus of this study is the challenges of rural tourism development in Zimbabwe. The study identified that there is a lack of sustainable interventions in the development of rural tourism which is catalyzed by the absence of rural tourism promotion strategy to support the sustenance of livelihoods through socio-economic transformation. Meaningful socio economic transformation in the African rural areas through tourism remains a major development challenge. Development initiatives through different forms of tourism in the rural communities, has to a less magnitude benefited the rural communities and have negatively impacted the socio–economic environment. A qualitative research methodology and case study design was employed in order to have a deeper understanding of the experiences of the society around this project. Face to face interviews and focus group discussions guides were used to collect primary data. Purposive and convenience sampling techniques was employed to select respondents. Data was analysed using the transformative theory and sustainable livelihoods theory and was organized into categories and themes. The study established that the absence of a strategy is caused by political instability, community conflict, lack of finance, marketing, poor communication, and limited knowledge of tourism. All the aforementioned reasons complement each other and poise a challenge to the sustainability of rural tourism development. For Zimbabwe to effectively transform its economy through tourism, the government needs to plan the process, formulate and implement relevant economic and social development strategies and policies. Although this dissertation is a case study of sustainable rural tourism in Zimbabwe, it can be used to appreciate the role of tourism in bringing about socio-economic transformation and sustaining livelihoods in developing countries.

- Description: Technology education is an important factor in every learner’s education. It contributes to the intellectual and practical development of the learners to enable them to cope with the challenges of a technological society. The main purpose of the study was to investigate the extent to which the learning and teaching of technology were implemented in schools in the Mthatha District. The main research question was: What are the challenges for the implementation of technology learning area in the Senior Phase? Research sub questions were: What support does the Department of Education give to educators?; To what extent have the objectives of implementing the technology learning area been achieved?; and, What suggestions do educators have to improve implementation of technology education? There were 20 Junior Secondary Schools involved in the study. There were two groups of samples: (a) the educators’ sample and (b) the learners’ sample. The educators’ sample: The sample size was 20 educators consisting of those who were teaching technology in either all the Senior Phase grades (Grade 7, 8 and 9) or at least in one of the grades in the senior phase in his/her school. On the researcher’s request, the Principal of each school nominated an educator and hence there was one educator in the educators’ sample from each of the 20 schools. The learners’ sample: The sample size was 40 learners consisting of at least two learners from each of the 20 schools. On the researcher’s request each educator in the educators’ sample nominated two learners from the senior phase. The instrument which was made to collect data was a researcher-designed questionnaire. The researcher personally visited each school involved in the study and gave the questionnaires to the two learners and one educator from that particular school to complete them independently within five days. The researcher personally re-visited each school on a day after the agreed-upon 5-day period but only after confirming over the phone that the questionnaires were indeed completed. The data were analyzed manually. The results obtained revealed that the implementation of the technology learning area is challenged by a number of problems. Those which were specifically identified were: lack of resources especially the rural schools; lack of people who are knowledgeable on Outcomes-based education (OBE) or the OBE modes of learning & teaching technology and its assessment methods, ineffectiveness arising out of large and overcrowded classes, challenges originating from or as a consequence of redeployment and the rationalization of educators and the lack of human resource to assist in the implementation of technology. The study showed the need for the provision of supportive service and continuous contact with educators to offer advice and assistance in order to improve the quality of technology teaching and learning in schools. The professional knowledge and skills of subject advisors as well as educators needed to be extended, refreshed and updated.

- Description: Background: The musculoskeletal demands placed on the lower limb musculature of fast bowlers over time have not received much attention. In particular, measures of muscle recruitment changes have, to the author’s knowledge, not been considered. Objective: The present study, therefore sought to establish any associations between an eight over, simulated fast bowling spell, and muscle activation patterns, power output, perceptual demands, and changes in performance. This will enable improvements in the development of training programmes. Methods: Players’ were required to attend two sessions in total. The purpose of the initial session was to collect specific demographic, anthropometric and physiological data and injury history information from each player. In addition, this first session allowed for habituation with the treadmill, the jump meter and all other equipment involved in experimentation. The second testing session involved electrode attachment sites being identified on player’s dominant leg. The areas were then shaved, wiped with an alcohol swab and left to dry, to ensure good connectivity. Pre- and post- measures of muscle activity and functional strength of the lower limbs were recorded in the Department of Human Kinetics and Ergonomics. The protocol took place at the Kingswood High Performance Centre, which is in close proximity to the initial testing site. The protocol involved players bowling eight overs (48 balls). During the protocol, accuracy, ball release speed and perceptual measures were recorded at the end of each over. After the protocol, players were driven back to the Human Kinetics and Ergonomics Department where post-testing measures were completed. The dependable variables of interest were muscle activation, functional strength of the lower limbs, ‘local’ ratings of perceived exertion (RPE), body discomfort, accuracy, and ball release speed. Results: For all muscles it was shown that, as the speed increased so did the muscle activity in players’ lower limbs. There were no significant changes in muscle activity preversus post-protocol. There was however, a general trend of decreasing muscle activity post protocol at higher testing speeds. There were significant (p<0.05) decreases in peak power following the simulated eight over bowling spell. ‘Local’ RPE displayed a significant (P<0.05) increase with each additional over and were observed to reach the ‘heavy’ category. The players’ highest discomfort area was in the lower back, with 13 players perceiving discomfort in this region following the eight over spell. The shoulder and chest were another two areas player’s indicated discomfort with eight players selecting the dominant shoulder. Seven players complained of the dominant side pectoral muscle, leading foot and dominant latissimus dorsi muscle being uncomfortable. Interestingly, the dominant pectoral showed the highest body discomfort ratings amongst players. There were no significant changes in accuracy between overs although there were large interindividual differences in accuracy points between players. The decrease in ball release speed observed during over seven was shown to be significantly (p<0.05) lower than overs one to four. Conclusion: The power output and perceived strain results of the players, appears to indicate the presence of fatigue in players. However, the results are not conclusive, as the fatigue was not shown in muscle recruitment patterns, as well as the body discomfort ratings. There was a non-significant trend observed in the lower limb muscle activation decreasing at higher speeds. Players were able to maintain accuracy. However, the significantly lower ball release speed observed during over seven showed players performance decreasing.

- Description: A significant proportion of the South African coastline is composed of both soft (mostly sand) and hard (mostly bedrock) substrata, i.e. “mixed”. This study described and classified macrobenthic assemblages of 20 Eastern Cape mixed substrate shores that differed in shore topography and the extent and position of intertidal rock and sand. A stratified random approach was used. Species richness, composition, abundance and environmental variables were determined. Commonly used beach indices were calculated. A total of 78 macrofaunal and 172 macroalgal species from rock substrate assemblages and 205 macrofauna species from sediment were recorded. Total species richness and richness per substratum exceeded that of sandy beaches devoid of rock and rocky shores with no sand. Rhodophyta were the most diverse and abundant algae, dominating all low-elevation rock surfaces as midlittoral and infralittoral turfs. Chlorophyta diversity was higher than at rocky shores, contributing more to cover-abundance at study sites and in microhabitats with an increased sand load. Sessile macrofauna species richness and abundance was lower than that of rocky shores. Polychaetes and crustaceans were the most diverse and abundant beach infauna. Species richness of both substrates declined from the low shore towards the high shore, but abundance trends varied substantially. The presence and extent of an intertidal biotope/subzone at either substrate depended on substrate availability.The supralittoral fringe in both substrate types was most often affected. Zonal overlap was evident on rock substrate: assemblages of raised midlittoral rock surfaces were enriched by species from lower surfaces sometimes leading to elimination of character taxa. Classification and ordination identified three potential mixed substrate shore biotic types: Biotic type A (Jania-Corallina- Polysiphonia turf) was characterised by robustly-textured algal turfs, a lowered predominance and diversity of polychaetes and an increase in crustacean abundance and diversity in sediment. Biotic type B (Polysiphonia-Tayloriella-Caulacanthus turf) had intermediately and biotic type C (Arthrocardia-Laurencia turf) the most sheltered eulittoral zones and beaches. DCCA identified the major environmental parameters affecting the macrobiota as: the level of wave energy, geological control of waves by hard substrate, sediment grain size and sediment inundation. A strong cross-shore wave attenuation results in sheltered sediments and midshore rock surfaces. Beach macrofauna were highly variable and diverse, which directly opposes previous perceptions about the sediment-bound biota of mixed substrate shores. The hierarchical cluster analysis produced a biotic classification of mixed substrate shores that was indicative of a biotic response to the total effects of leading environmental parameters. Macrobenthos of rock surfaces and sediment therefore showed potential to be used as an alternative or complementary to physical characteristics in classifying mixed substrate shores.

- Description: Heat Shock 40 kDa proteins (Hsp40s) partner with heat shock 70 kDa proteins (Hsp70s) in facilitating, among other chaperone activities; correct protein transport, productive protein folding and assembly within the cells; under both normal and stressful conditions. Hsp40 proteins regulate the ATPase activity of Hsp70 through interaction with the J-domain. Plasmodium falciparum Hsp70s (PfHsp70s) do not contain a Plasmodium export element (PEXEL) sequence although PfHsp70-1 and PfHsp70-3 have been located outside of the parasitophorous vacuole. Studies reveal that a type I P. falciparum (PfHsp40) chaperone (PF14_0359) stimulates the rate of ATP hydrolysis of the cytosolic PfHsp70 (PfHsp70-1) and that of human Hsp70A1A. PFE0055c is a PEXEL-bearing type II Hsp40 that is exported into the cytosol of P. falciparum-infected erythrocytes; where it potentially interacts with human Hsp70. Studies reveal that PFE0055c associates with structures found in the erythrocyte cytosol termed “J-dots” which are believed to be involved in trafficking parasite-encoded proteins through the erythrocyte cytosol. If P. falciparum exports PFE0055c into the host cytosol, it may be proposed that it interacts with human Hsp70, making it a possible drug target. The effect of PFE0055c on the ATPase activity of human Hsp70A1A has not been previously characterised. Central to this study was bioinformatic analysis and biochemical characterisation PFE0055c using an in vitro (ATPase assay) approach. Structural domains that classify PFE0055c as a type II Hsp40 were identified with similarity to two other exported type II PfHsp40s. Plasmids encoding the hexahistidine-tagged versions of PFE0055c and human Hsp70A1A were used for the expression and purification of these proteins from Escherichia coli. Purification was achieved using nickel affinity chromatography. The urea-denaturing method was used to obtain the purified PFE0055c whilst human Hsp70A1A was purified using the native method. PFE0055c could stimulate the ATPase activity of alfalfa Hsp70, although such was not the case for human Hsp70A1A in vitro.

- Description: Different approaches to surface modification were investigated in this work on gold, glassy carbon, multi-walled carbon nanotube paper and on single-walled carbon nanotubes adsorbed on glassy carbon. These approaches include electrochemical grafting, electropolymerisation, click chemistry, axial ligation, adsorption and self-assembled monolayers. The modified surfaces were characterised using a variety of techniques; predominantly electrochemistry, scanning electrochemical microscopy and X-ray photoelectron spectroscopy. For the formation of self-assembled monolayers on gold, four new manganese(III) phthalocyanines (1a-d), octa-substituted at the peripheral position with pentylthio, decylthio, benzylthio, and phenylthio groups were synthesized and characterised. X-ray photoelectron spectroscopy was used to show the formation of a sulphur-gold bond. A number of approaches using 4-azidoaniline (2a) combined with azide-alkyne click chemistry and electrochemistry were also used to anchor ferrocene and pyridine moieties on to the carbon surfaces, including direct in situ diazotation and grafting, electropolymerisation, and the synthesis of the diazonium salt followed by grafting. Iron phthalocyanine was linked to the pyridine-clicked surfaces through axial ligation, where the strong axial bond formed by the interaction between the central metal and the lone pair of the nitrogen in the pyridine group resulted in stable modified electrodes. The potential of these surfaces for the detection of analytes such as thiocyanate, hydrazine and sulphite are briefly shown as well. This work also describes for the first time the possibility of performing local micro-electrochemical grafting of a gold substrate by 4-azidobenzenediazonium (2b) using scanning electrochemical microscopy in a single and simple one step approach, without complications from adsorption.

- Description: This work presents the syntheses, photophysical and photochemical characterization of arylthio zinc phthalocyanines and their gold nanoparticle conjugates. Spectroscopic and microscopic studies confirmed the formation of the phthalocyanine-gold nanoparticle conjugates which exhibited enhanced photophysicochemical properties in comparison to the phthalocyanines. The studies showed that the presence of gold nanoparticles significantly lowered fluorescence quantum yields and lifetimes. However, this interaction did not restrict the formation of excited singlet and triplet states and hence the formation of singlet oxygen required for photocatalysis. The conjugates showed significantly higher singlet oxygen quantum yields and therefore enhanced photocatalytic activity compared to the phthalocyanines. The zinc phthalocyanines and their gold nanoparticle conjugates were successfully incorporated into electrospun polymer fibers. Spectral characteristics of the functionalized electrospun fibers indicated that the phthalocyanines and phthalocyanine-gold nanoparticle conjugates were bound and their integrity was maintained within the polymeric fiber matrices. The photophysical and photochemical properties of the complexes were equally maintained within the electrospun fibers. The functionalized fibers were applied for the photoconversion of 4-chlorophenol and Orange G as model organic pollutants. , Microsoft� Word 2010 , Adobe Acrobat 9.53 Paper Capture Plug-in

- Description: This study examines the impact of children’s grants on household access to food, education and health care. In the face of increased poverty and socio-economic inequalities, social grants are a critical poverty alleviation intervention implemented by the government of South Africa. The children’s grants are offered as part of the social security system which is provided for in the Republic of South Africa Constitution of 1996 and the Social Assistance Act of 2004. The basic needs conceptual framework is the lens informing the focus of the study. Among other major findings, the study reveals that (a) childrens grants play a critical role in improvement of access to food, health care and education, (b) childrens grants are used as collateral, to access short term loans, and (c) social networks and home gardens play a significant role in aiding children’s grants to ensure household access to food, education and health care.

- Description: When implemented within a favourable legislative framework, Foreign Direct Investment (FDI) can produce domestic growth-enhancing spillovers in host countries. Other potential positive effects include the provision of investment capital, the creation of local employment and the transfer of sophisticated technology or advanced knowledge. African nations in particular have been historically reliant on externally-provided funds. Prevailing low income levels, marginal savings rates and the absence of functioning financial markets necessary to provide local start-up capital continue to keep Africa reliant on foreign inflows. Considering China’s increasing financial commitments to Sub- Saharan Africa (SSA) over the last decade, this study examines the state of current Sino-African investment relationships. Specific attention is paid to the outcomes of this strategic bilateral alliance in order to determine whether or not a mutually beneficial investment relationship has evolved. The distinct nature and structure of, the motivation behind and the most significant determinants of Chinese FDI to SSA are all analysed in accordance with traditional FDI theories. A case study approach is used to establish whether China’s contemporary interest in SSA differs from historical investments and to also investigate country-specific commonalities and differences. Of particular relevance to SSA are resource-backed Chinese loans that finance major infrastructure projects in host nations. Interestingly, a lot of the Sino-African investment packages resemble similar deals struck between China and Japan in the 1970s. The results of this study indicate that China’s investment motives seem more diverse than initially expected. Resource-seeking, profit-seeking and market access-seeking reasons appear to be the most important motives. After establishing the Top- Ten recipients of Chinese FDI in SSA, these nations are then classified into three major categories: resource-, oil- or agricultural-rich nations. Undiversified resource- or oil-rich economies are found to have secured the largest shares of Chinese FDI. This study suggests that China’s contemporary “African Safari” is an unconventional way of providing financial assistance. Rather than solely supplying FDI, China finances a diverse mix of instruments, the most important being concessional loans, export credits, zero-interest loans and the establishment of Special Economic Zones. A profound difference to traditional Western investment packages is China’s non-interference approach. Accordingly, Beijing not only refrains from intervening in host countries’ domestic affairs but also refuses to attach formal conditionalties to its loans. China’s “financial safari” into Africa has produced many positive as well as negative effects in host countries. Nevertheless, it would seem that the positive effects outweigh the negative and China’s FDI could contribute to sustainable development in SSA

- Description: Adventure tourism (AT), defined as “a broad spectrum of outdoor touristic activities,often commercialized and involving an interaction with the natural environment away from the participants’ home range and containing elements of risk,” (Hall, 1992, p. 143) is currently one of the fastest growing sub-sectors of the tourism industry (Buckley 2010). Because it has emerged relatively recently as a field of study, a number of scholars have called for ongoing research in the area, see Swarbrooke (2003), Pomfret (2006), Buckley (2010), Rogerson (2007), and Williams & Soutar (2005). Much of this research, to date, has focused on marketing, injury caused by AT participation, environmental impacts, and the broad notion of “risk” associated with AT. The problem is that little of this work has focused on the significance of the environment in adventure tourism – an important element inherent in its definition. Thus, this thesis aims to move beyond a general risk-based analysis of AT, and focus on the role of the environment. This is done through a human-environment interaction approach undertaken in Tsitsikamma Village where five adventure tourist operations are based. The first step in operationalizing this approach was to develop a conceptual framework that integrated adventure tourism into a general framework on humanenvironment interaction. The second step was to use a research instrument which enabled one to examine the influence of the environment on human motivations and adventure tourism experiences, and not only the influence of humans on the environment. The former was accomplished through questionnaires based on external, environmental elements that attract adventure tourists as well as inherent personality traits impel such tourists to participate in AT. The latter, based on interviews and participant perceptions, sought to establish the significance of impacts on the environment as well as initiatives taken by AT companies to minimize environmental damage. The findings show that although risk/thrill does play a role, AT motivations and experiences are complex and multidimensional. The environment does significantly influence both motivations and even more so AT experiences. Furthermore, there are distinct differences between the motivations and experiences of participants in different types of AT activities, indicating that generalizing the industry as whole neglects these significant differences. In terms of influences on the environment, the results show that most AT operators in the Tsitsikamma have some consideration for environmental protection and take some initiatives to minimize environmental damage, though the degree to which this occurs differs significantly. Furthermore, activity participants do not believe that the activities have a strong negative impact on the environment, though the majority acknowledge small impacts. The types of impacts observed by participants vary significantly between companies. This thesis demonstrates the manner in which the two-way relationship between humans and the environment manifests itself in the commercial AT industry. The result is a well-rounded examination of the influence of human-environment interaction on AT participants.

- Description: The aim of this study was to investigate whether patients were satisfied with midwifery services rendered at the two Community Health Centres in the Eastern Cape Province.The study sites were Empilweni Gompo and Nontyatyambo Community Health Centres. Descriptive quantitative study design was employed, using a questionnaire with closed and open ended questions as the data collecting tool. Likert Scale was used to measure the following variables: quality care variables to measure level of satisfaction with midwifery services rendered and to determine positive and negative perceptions regarding quality of care received during antenatal, labour and postnatal period. Non-random convenience sampling of sixty pregnant women, thirty from each Community Health Centre, with two or more antenatal subsequent visits and forty postpartum women, twenty from each health facility, six hours after delivery if there were no complications. Out of 60 participants interviewed n=60 (100 percent) agreed that individual counseling and importance of HIV testing was explained.The majority of participants n=53(88 percent) disagreed that they were educated about focused antenatal visits. Out of 60 participants interviewed n=41(68 percent) agreed that delivery plan formed part of their ANC visits and n=18 (30 percent) disagreed. Of the 60 participants interviewed n=11(18 percent) agreed that they were told that they had the right to choose labour companions and n=48 (80 percent) disagreed.Out of 60 participants interviewed n=23 (38 percent) stated that they waited a long period of time without being attended to by midwives. In general, the study revealed high satisfaction level with intrapartum and postnatal care due to functional accessibility of both Community Health Centres. Both health centres delivered normal healthy babies and mothers. However, the participants were dissatisfied with antenatal care rendered at the two facilities. The researcher’s recommendations were based on the closing of gaps that were identified with regard to the implementation of Basic Antenatal Care; birth companions: health education deficiency; community involvement and participation.

- Description: Scientists started to study the relationship between changing weather patterns and the emission of carbon dioxide (CO2) and other harmful gasses. They soon discovered compelling evidence that CO2 concentration and other gases have been increasing and it was causing temperatures to increase in certain areas on the earth, which disturb historic weather patterns. Climate change has become a very popular field of study in the modern science. Europe first introduced measures to reduce carbon emissions but it was the Kyoto in 1997 where global leaders were asked to participate in a joint protocol to reduce greenhouse gases. South Africa responded to climate change challenges in 2008 with the Long term Mitigation Scenarios (LTMS). The Integrated Resource Plan for electricity to 2030 was developed from the LTMS scenarios and after some major amendments it was accepted and promulgated by Government and has recently been included in the National Development Plan to 2030 (NDP). There are concerns about the achievability of some of the objectives listed in the NDP and this study explored the IRP2010 as the proposed strategy to meet energy demand and reduce emissions. The purpose for this study was to answer this question: Is there an optimum climate change mitigation strategy for South Africa and how can the effect thereof be simulated on economic growth? Through primary and secondary research during the study it was possible to define some 32 categories of energy producing assets that are commercially active or nearly market-ready. The characteristics of the various assets and the relevant fuel are defined in mathematical equations. It was found that the three portfolios that matched the 450TWh electricity requirement would perform substantially better than the NDP portfolio in terms of cost and similar on emissions with marginally fewer employment opportunities created. The proposed electricity strategy in this study was 390TWh and 33.5 Million tonnes of oil consumption by 2030. This strategy was substantially more affordable than the 450TWh strategy. Trends in the Supply and Use tables since 1993 were studied and then forecasted to 2030 to determine consumption levels on electricity and liquid fuel into the future. It was found that electricity demand is seriously overestimated and South Africa would end up with large excess capacity in electricity infrastructures if the NDP energy strategy (IRP2010) is implemented. It is concluded that the NDP energy strategy to 2030 is based on an incorrect electricity demand forecast. It would lead to excessive investment in an electricity infrastructure. Government has confirmed that part of the new infrastructure would be nuclear. It is also found that NDP has not clearly supported nuclear as part of the strategy. Nuclear is partly the reason why the capital requirement of the NDP portfolio is so much higher than the other portfolios. It is the conclusion of this study that South Africa do not need to invest in a nuclear build programme as the electricity demand would be adequately covered by adding the new Medupi and Kusile power stations, Ingula pump storage scheme, some wind and solar renewables, electricity from cogeneration, biogas, biomass, small hydro and imported hydro from neighbour countries. To invest in electricity capacity to generate 450TWh annually by 2030 would result in excessive energy cost, GDP growth could be up to 1% lower due to underperforming capital investments in the electricity infrastructure and higher energy cost would lead to a decline in global competitiveness.

- Description: Water is recognised as a key driver for social and economic development in the Zambezi basin. The basin is riparian to eight southern African countries and the transboundary nature of the basin’s water resources can be viewed as an agent of cooperation between the basin countries. It is possible, however, that the same water resource can lead to conflicts between water users. The southern African Water Vision for ‘equitable and sustainable utilisation of water for social, environmental justice and economic benefits for the present and future generations’ calls for an integrated and efficient management of water resources within the basin. Ensuring water and food security in the Zambezi basin is, however, faced with challenges due to high variability in climate and the available water resources. Water resources are under continuous threat from pollution, increased population growth, development and urbanisation as well as global climate change. These factors increase the demand for freshwater resources and have resulted in water being one of the major driving forces for development. The basin is also vulnerable due to lack of adequate financial resources and appropriate water resources infrastructure to enable viable, equitable and sustainable distribution of the water resources. This is in addition to the fact that the basin’s economic mainstay and social well-being are largely dependent on rainfed agriculture. There is also competition among the different water users and this has the potential to generate conflicts, which further hinder the development of water resources in the basin. This thesis has focused on the Zambezi River basin emphasising climate variability and climate change. It is now considered common knowledge that the global climate is changing and that many of the impacts will be felt through water resources. If these predictions are correct then the Zambezi basin is most likely to suffer under such impacts since its economic mainstay is largely determined by the availability of rainfall. It is the belief of this study that in order to ascertain the impacts of climate change, there should be a basis against which this change is evaluated. If we do not know the historical patterns of variability it may be difficult to predict changes in the future climate and in the hydrological resources and it will certainly be difficult to develop appropriate management strategies. Reliable quantitative estimates of water availability are a prerequisite for successful water resource plans. However, such initiatives have been hindered by paucity in data especially in a basin where gauging networks are inadequate and some of them have deteriorated. This is further compounded by shortages in resources, both human and financial, to ensure adequate monitoring. To address the data problems, this study largely relied on global data sets and the CRU TS2.1 rainfall grids were used for a large part of this study. The study starts by assessing the historical variability of rainfall and streamflow in the Zambezi basin and the results are used to inform the prediction of change in the future. Various methods of assessing historical trends were employed and regional drought indices were generated and evaluated against the historical rainfall trends. The study clearly demonstrates that the basin has a high degree of temporal and spatial variability in rainfall and streamflow at inter-annual and multi-decadal scales. The Standardised Precipitation Index, a rainfall based drought index, is used to assess historical drought events in the basin and it is shown that most of the droughts that have occurred were influenced by climatic and hydrological variability. It is concluded, through the evaluation of agricultural maize yields, that the basin’s food security is mostly constrained by the availability of rainfall. Comparing the viability of using a rainfall based index to a soil moisture based index as an agricultural drought indicator, this study concluded that a soil moisture based index is a better indicator since all of the water balance components are considered in the generation of the index. This index presents the actual amount of water available for the plant unlike purely rainfall based indices, that do not account for other components of the water budget that cause water losses. A number of challenges were, however, faced in assessing the variability and historical drought conditions, mainly due to the fact that most parts of the Zambezi basin are ungauged and available data are sparse, short and not continuous (with missing gaps). Hydrological modelling is frequently used to bridge the data gap and to facilitate the quantification of a basin’s hydrology for both gauged and ungauged catchments. The trend has been to use various methods of regionalisation to transfer information from gauged basins, or from basins with adequate physical basin data, to ungauged basins. All this is done to ensure that water resources are accounted for and that the future can be well planned. A number of approaches leading to the evaluation of the basin’s hydrological response to future climate change scenarios are taken. The Pitman rainfall-runoff model has enjoyed wide use as a water resources estimation tool in southern Africa. The model has been calibrated for the Zambezi basin but it should be acknowledged that any hydrological modelling process is characterised by many uncertainties arising from limitations in input data and inherent model structural uncertainty. The calibration process is thus carried out in a manner that embraces some of the uncertainties. Initial ranges of parameter values (maximum and minimum) that incorporate the possible parameter uncertainties are assigned in relation to physical basin properties. These parameter sets are used as input to the uncertainty version of the model to generate behavioural parameter space which is then further modified through manual calibration. The use of parameter ranges initially guided by the basin physical properties generates streamflows that adequately represent the historically observed amounts. This study concludes that the uncertainty framework and the Pitman model perform quite well in the Zambezi basin. Based on assumptions of an intensifying hydrological cycle, climate changes are frequently expected to result in negative impacts on water resources. However, it is important that basin scale assessments are undertaken so that appropriate future management strategies can be developed. To assess the likely changes in the Zambezi basin, the calibrated Pitman model was forced with downscaled and bias corrected GCM data. Three GCMs were used for this study, namely; ECHAM, GFDL and IPSL. The general observation made in this study is that the near future (2046-2065) conditions of the Zambezi basin are expected to remain within the ranges of historically observed variability. The differences between the predictions for the three GCMs are an indication of the uncertainties in the future and it has not been possible to make any firm conclusions about directions of change. It is therefore recommended that future water resources management strategies account for historical patterns of variability, but also for increased uncertainty. Any management strategies that are able to satisfactorily deal with the large variability that is evident from the historical data should be robust enough to account for the near future patterns of water availability predicted by this study. However, the uncertainties in these predictions suggest that improved monitoring systems are required to provide additional data against which future model outputs can be assessed.

- Description: Water is recognised as a key driver for social and economic development in the Zambezi basin. The basin is riparian to eight southern African countries and the transboundary nature of the basin’s water resources can be viewed as an agent of cooperation between the basin countries. It is possible, however, that the same water resource can lead to conflicts between water users. The southern African Water Vision for ‘equitable and sustainable utilisation of water for social, environmental justice and economic benefits for the present and future generations’ calls for an integrated and efficient management of water resources within the basin. Ensuring water and food security in the Zambezi basin is, however, faced with challenges due to high variability in climate and the available water resources. Water resources are under continuous threat from pollution, increased population growth, development and urbanisation as well as global climate change. These factors increase the demand for freshwater resources and have resulted in water being one of the major driving forces for development. The basin is also vulnerable due to lack of adequate financial resources and appropriate water resources infrastructure to enable viable, equitable and sustainable distribution of the water resources. This is in addition to the fact that the basin’s economic mainstay and social well-being are largely dependent on rainfed agriculture. There is also competition among the different water users and this has the potential to generate conflicts, which further hinder the development of water resources in the basin. This thesis has focused on the Zambezi River basin emphasising climate variability and climate change. It is now considered common knowledge that the global climate is changing and that many of the impacts will be felt through water resources. If these predictions are correct then the Zambezi basin is most likely to suffer under such impacts since its economic mainstay is largely determined by the availability of rainfall. It is the belief of this study that in order to ascertain the impacts of climate change, there should be a basis against which this change is evaluated. If we do not know the historical patterns of variability it may be difficult to predict changes in the future climate and in the hydrological resources and it will certainly be difficult to develop appropriate management strategies. Reliable quantitative estimates of water availability are a prerequisite for successful water resource plans.

By researching the role of indexical signs and strategies, particularly as they are deployed by the artist Doris Salcedo, I explore the capacity for these traces to not only effectively mark and memorialise loss, but to also convey the state of loss as experienced by the bereaved without providing a narrative account of the events which preceded them. The domestic ritual of washing is both alluded to and used as a metaphor in etchings, photographic prints and readymade objects to illustrate my concerns, with particular emphasis on the dialectic between what is revealed or concealed. Using representations or traces of this task of laundry to examine this dialectic between concealment and revelation, I comment on the anxiety of dealing with incomplete narrative inheritances by considering how traces of the past which impose themselves on the present may affect both remembrance and the ritual of loss, while also taking into account the complexities behind the disclosure of sensitive information in families.

- Description: The broad objective of the study was to investigate the limiting factors that prevent a breakthrough of emerging farmers to commercial agricultural farming industry. The research objectives were to describe the demographic characteristics such as age, education, farming skills and experience; determine the required support services needed; and inform the limiting factors that prevent breakthrough of emerging farmers to enter commercial agricultural industry. The study was conducted in King William’s Town area through structured questionnaires administered by the researcher. A sample of 50 emerging farmers was drawn in the area. The majority of households in the area depend on subsistence farming for household survival. Results indicated that emerging farmers are faced with poor physical infrastructure such as implements to better their production as well as low education levels which results as an inability to interpret market information to be used in production planning. It is also clear that the farmers face a lack of market infrastructure, poor roads, lack of market information, lack of transportation to markets and high transportation costs. The majority of the farmers were old and the youth was not engaged in agriculture. The findings showed that there is an insufficient role from government with regards to emerging farmer support and providing the required infrastructure to access markets or improving rural infrastructure. As a result the majority of the farmers are trapped in a cycle of poverty. The following policy recommendations are suggested: Financial services such as credit must be made available to emerging farmers at reasonable interest rates such as low interest rate subsidies to emerging farmers up until commercialisation. The requirements for emerging farmers to access loans, funding or credit should be restructured or adjusted to the ability of the farmer to repay the credit rather than the availability of title deeds or assets as collateral. Extension officers should regularly visit the localities were emerging farmers are farming have a better understanding of their farming areas, farming methods and improve their communication with the farmers. Lastly the land reform initiatives should be re-organised or developed if necessary to ensure efficient re-allocation of land. The policies should be developed to focus on both the individual farm plots and the collective rights.

- Description: The aim of this study was to analyse the communication practices of Non-Governmental Organisations (NGOs) in their poverty alleviation programmes, using Deutsche Weltihungerhilfe German Agro Action (GAA) in Gokwe South Rural District, Midlands Province, Zimbabwe as a case study. The study was based on the premise that effective communication is essential for successful poverty alleviation programmes. Communication facilitates the diffusion of innovations and encourages active participation by local people in programmes. It is also clear that despite several attempts to end the social malaise, poverty still persists. While several factors such as corruption, misappropriation of funds and misdirection of programs are not innocuous considering the failures of poverty alleviation programmes, communication is an indispensible tool to their success. It therefore becomes imperative that the communication practices be evaluated to identify the missing links. It is evident that by so doing, going forward, NGOs can effectively communicate with the local people and advances towards poverty alleviation can be realised. To this end, third world countries amongst them Zimbabwe and particularly rural communities, Gokwe included continue to suffer from poverty despite a number of programmes to address the pandemic by NGOs. The study was guided by the tenets of the Diffusion of innovations and Participatory development communication theories. These theories were considered the most applicable in terms of the research subject. The study employed both quantitative and qualitative research methods and it was carried out in four of the wards in the district. The research methods were applied to solicit information from the rural people on how communication took place between the organisation and the community. The study found out that GAA used mainly the Indigenous Communication Systems (ICSs) in form of meetings and interpersonal face-toface communication modes. Names of projects were also fairly used for communication. The Modern Communication Systems (MCSs) used were cell phones and letters. GAA used local Page v languages mainly Shona and Ndebele and was flexible with the use of the indigenous languages. English language was also used for communication. The communication modes as well as the languages used were effective. The research also analysed and evaluated the communication practices by GAA. The study found out that the organisation effectively used the communication modes which were available for use but there were limitations in terms of access to other communication modes, especially the modern mediums due to poor infrastructure, state monopolisation of the mass media industry using regulations and fear of political persecution. The modern communication modes which GAA did not have access to could facilitate the diffusion of innovations and provide adequate information for active participation by the rural people in poverty alleviation programmes. The study also found out that only one person had heard about GAA through radio and no-one heard about GAA through the television, magazine or newspaper. The orgnanisation did not use these forms of mass media. In addition, the integration of ICSs and MCSs would provide an effective feedback system in Gokwe South Rural District. The researcher suggested the Tilled Communication Field approach whereby every stakeholder is required to make sure that the ICSs and MCSs are available for use by anyone at anytime for development purposes. There is need to give everyone adequate opportunity to use all the communication systems and users are advised to use communication for positive purposes, poverty alleviation included.

- Description: Nowadays young people and other members of the society often find themselves in many malpractices such as rape, suicide, murder dropping out of school and other harmful activities due to the use of cannabis sativa (dagga) which is on the rise. This study concentrated on the use of cannabis sativa (dagga) in Mzintlava, Ngquza Hill Local Municipality in the Eastern Cape Province of South Africa. Young people are actually the victims of the consequences of the use of dagga. Indications are that parents often ignore their children to use cannabis sativa until they can no longer stop them. Earlier researches on substance use in South Africa have always been descriptive. This resulted in sketchy understanding of factors that predisposed young children to the use and even abuse of dagga and the reasons why parents and the community underestimated the practice until the stage of addiction. Without this understanding, it will be difficult to introduce effective ways of abolishing dagga use among young children and other members of the community. Finding effective measures to prevent substance use has been difficult. Research is therefore needed in order to understand the basis of the problem. This study attempts to examine factors that make parents and the communities to leave children to taking substances until the stage where they can longer stop them. It will also lead to establishing factors that put young children or teenagers particularly at risk to the use of dagga.

- Description: Poverty is a major challenge in most developing countries. Key challenges of the government are to alleviate poverty and propel citizens toward wealth creation through development of enterprises across all sectors and to address the problem of unemployment. In Kenya, the SME sector comprises of about 99% of private sector enterprises and is prolific in employment and wealth creation. Despite this critical role played by SMEs in growing the economy, they remain outside the formal banking sector, especially in Africa. Although the number of MFOs since the 1980s has increased, the demand for financial services is largely unmet. However, MFOs are increasingly experiencing competition from new entrants and commercial banks that have developed financial models to target SMEs. MFOs are required to formulate and implement competitive strategies to enable them achieve sustainable growth and compete with commercial banks. However, strategy implementation is generally accepted as a challenge across organisations and it is often easier to formulate strategies than implementing it. Despite the need to address strategy implementation challenges across organisations, there is a greater focus by practitioners and researchers regarding strategy formulation than implementation. Consequently, this study aimed at assessing the level of strategy implementation in MFOs and factors that affect strategy implementation in MFOs. The ultimate objective was to develop a hypothetical model that could be used to improve strategy implementation in microfinance organisations in Kenya. This quantitative study used purposive sampling to select MFOs that are members of the Association of Microfinance Institutions (AMFI) in Kenya, completing a selfadministered structured questionnaire. In total, 135 MFOs were involved in this study and a total sample size of 300 managers was used in this study. This study considered fourteen factors to have an influence on the level of strategy implementation of MFOs in Kenya and hence fourteen null-hypotheses were formulated and tested. The content factors included stakeholder involvement in strategy development and the quality of strategies. The context factors included organisational structure and culture, strategic leadership and alignment of strategy to market conditions. The operational process factors included operational planning, monitoring and review of progress, teamwork, resources allocation, people-strategy fit, effective communication, strategic and management control systems and information resources. It is assumed that if all these critical strategy implementation factors are addressed, MFOs should be able improve their level of strategy implementation, ultimately leading to improved performance. The outcome factors considered were improved financial sustainability and outreach of MFOs. Advanced statistical analyses were used to analyse the data, such as factor analysis, regression and correlation analysis to assess the hypothesised relationship between the dependent and independent variables of this study. The empirical results revealed that the level of strategy implementation in MFOs in Kenya is moderate to high and content, context and operational factors do have an influence on the level of strategy implementation. However, operational factors have a more significant positive linear relationship with level of strategy implementation than the other two factors. There is also a positive relationship between the level of strategy implementation and financial sustainability and outreach by MFOs. This study has contributed to the existing body of knowledge by developing a hypothetical model that can be utilised by MFOs as well as other organisations to improve the level of strategy implementation resulting in better performance. The findings of the study can also inform strategy formulation and implementation of MFOs in Kenya, but also in other developing countries, to become more competitive. This study could also help MFOs and other organisations to put in place structures, systems, people and other resources required to attain a high level of strategy implementation. This study provides useful and practical guidelines in dealing with content, context and operational factors affecting strategy implementation in any organisational setting.

- Description: Poverty is a major challenge in most developing countries. Key challenges of the government are to alleviate poverty and propel citizens toward wealth creation through development of enterprises across all sectors and to address the problem of unemployment. In Kenya, the SME sector comprises of about 99% of private sector enterprises and is prolific in employment and wealth creation. Despite this critical role played by SMEs in growing the economy, they remain outside the formal banking sector, especially in Africa. Although the number of MFOs since the 1980s has increased, the demand for financial services is largely unmet. However, MFOs are increasingly experiencing competition from new entrants and commercial banks that have developed financial models to target SMEs. MFOs are required to formulate and implement competitive strategies to enable them achieve sustainable growth and compete with commercial banks. However, strategy implementation is generally accepted as a challenge across organisations and it is often easier to formulate strategies than implementing it. Despite the need to address strategy implementation challenges across organisations, there is a greater focus by practitioners and researchers regarding strategy formulation than implementation. Consequently, this study aimed at assessing the level of strategy implementation in MFOs and factors that affect strategy implementation in MFOs.
