A research report submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science by coursework and research report. Johannesburg, 13 May 2014. / The African baobab (Adansonia digitata) is a multi-purpose tree that is important among African villages as it provides food and a range of raw materials. Its fruits provide essential nutrients and are sold to generate income. As baobab fruits are important to the livelihoods of many people, it is important to understand the causes of differences in fruit production in order to maximise use and for conservation purposes. Many studies have examined fruit production to understand the causes of variation in fruit yields. In Venda, a region northern South Africa, differences in baobab fruit yield has been recorded for 8 years, thus classifying individual trees as either poor producers or producers (Venter and Witkowski, 2011). Poor producers are adult trees producing less than five fruits each year and some not producing at all. On the other hand, adult trees producing more than five fruits each year are referred as producers. Causes of this difference in fruit production have not been identified. Among other factors, the observed difference in fruit production could be related to differences in ploidy-level among baobab trees. Importantly, few or no studies to our knowledge have been carried out to confirm whether differences in fruit production among baobab trees are related to a difference in ploidy-level. The well-known and widespread mainland African baobab, Adansonia digitata, is known to be a tetraploid (four sets of chromosomes). Recently, a difference in ploidy-level has been revealed. A new diploid species, Adansonia kilima, has been identified in Africa (Pettigrew et al., 2012). Morphological characteristics (floral, pollen, and stomatal size and density), ploidy, and molecular phylogenetics suggest the presence of a new species. This new species has been reported to overlap the well-known and widespread tetraploid A. digitata’s distribution in Venda. Consequently, the presence of a diploid species that reproduces with a tetraploid species could result in triploid progeny and contribute to the observed differences in fruit production in these baobab trees. The objectives of this study were (i) to assess if there is any difference in ploidy-level between the poor producer and producer baobab trees in Venda using flow cytometry, (ii) to assess if stomatal density and size correlate to differences in ploidy-level, and (iii) to use microsatellites to estimate levels of gene flow between these baobab trees. Morphological results showed that stomatal size and density were not significantly different between poor producer and producer trees and these features may not be true indicators of difference in ploidy-level for baobabs. Gene flow results showed that there was high mean genetic heterozygosity and low population differentiation expressed in all populations. This suggests that inbreeding was not responsible for the differences in fruit production between poor producer and producer trees. Low population differentiation observed among the populations indicated that a large number of common alleles were shared among the populations. Therefore, the high gene flow observed among the populations suggests that poor producer and producer trees were sharing alleles, and what is causing the differences in fruit production remains unclear.

Thesis (M.Dev. (Planning and Management)) -- University of Limpopo, 2022 / Development projects, including the Fetša Tlala Initiative, were designed to contribute to the National Development Plan, 2030. The objectives of this research assessed how effective the Fetša Tlala project was in improving food and nutrition security of women farmers and the degree of empowerment the project afforded them. A semi-structured interview guide was applied to 16 purposefully selected respondents during face-to-face interviews as the data collection method. The findings indicated that physical resources provided to beneficiaries contributed to the effectiveness of the project. However, the inconsistent institutional support provided by the project initiators were considered to detract from the effectiveness. The findings also revealed that the beneficiaries were empowered by the opportunities afforded through the initiative, but were further empowered by their own resilience in the face of adversity. The study concludes by recommending the continuation of the project with improved institutional support.

Thesis (MPAM.) -- University of Limpopo, 2022 / The study presents findings that examined the nature and extent of community participation in the Integrated Development Planning (IDP) processes as a means of improving local governance at the Polokwane Local Municipality. The study argues for a need to empower communities with knowledge on the available mechanism as a way of fulfilling the dream of a culture of participation. This is to increase unified perception about the value of community participation in improving local governance. However, local governance accountability can be gauged by the extent to which they practise community participation in decision-making in facing up to the challenges of the day. This is done by putting or encouraging community participation in the processes that would help face up to the challenges of the day, including the IDP processes. The study applied a mixed-methods design and a combination of thematic data analysis and Microsoft Excel (spreadsheet) to analyse data gathered. Structured questionnaires were distributed to respective community members in the selected communities: two villages of Potse and Mahlohlokwe; two townships Mankweng Unit D and Mankweng Zone 1; two suburbs - Flora Park and Ivy Park. Furthermore, faceto- face interviews were conducted with the Polokwane municipal officials responsible for IDP, municipal manager, IDP manager and councillors of selected communities. Findings of the study showed that community participation in the IDP processes was viewed as one of the ways of enabling interaction between local government and citizens. However, citizens faced challenges in the process of community participation and that impacted on the level of community participation. It should, therefore, be borne in mind that to improve local governance, it is necessary to look at the extent to which communities are engaged in the processes of improving local governance. Participation of communities in the development planning of their communities can thus help improve local governance. Therefore, community participation should be widely applied in the local government field to enable good governance and sustainable development.

Thesis (MDev.) -- University of Limpopo, 2016 / The introduction of privatisation after 1994 has left many people in Polokwane without employment. The majority of the jobs were given to few people who always provide services through tenders. Most of the departments were no longer hiring people because of the tendering process. The process has made many departments and municipalities to absorb labour force in the public sector. Due to lack of employment in different regions in Limpopo, the provincial Department of Public Works has started an Expanded Public Works Programme (EPWP) to alleviate poverty in the province. However, the management of these projects became a problem to most of the government officials in the municipalities, provincial departments and municipalities are fraught with challenges such as lack of managerial traits, technical and skills related to project management. Polokwane local municipality is not excluded from the above problems, hence the study on the investigation of the management of EPWP towards job creation in Polokwane local municipality. In order to understand the total context of the managerial flaws faced by Polokwane local municipality in Limpopo an in-depth empirical research and interviews were conducted to collect data from government official and employees in the study area. The finding of the study suggests that lack of managerial traits, technical skills, lack of participation, non-compliance with work ethics, monitoring and evaluation were regarded as the greatest challenges in the management of EPWP in Polokwane local municipality. Due to the above challenges, most of the projects are not completed on time because of the lack of qualified project managers. Lack of qualified personnel also contributed to poor quality of service delivery in the area of the study. The study revealed that the projects can alleviate poverty if can be managed and implemented by qualified managers and employees with relevant skills. Therefore, the study calls for the Department of Public Works to appoint qualified and experienced civil engineers to monitor and evaluate the implementation of EPWP projects in Polokwane local municipality.

Thesis (MPAM.) -- University of Limpopo, 2022 / This study investigated the effectiveness of the national road safety strategy towards reducing accidents and road fatalities on the N1 in the Limpopo Province. Qualitative research was conducted to determine the experiences of the traffic law enforcement officers in implementing the road safety strategy in the Limpopo Province. Primary qualitative data were collected using the semi-structured questionnaire supplemented by telephonic interviews. Two groups of participants including the traffic law enforcement officers (n=10) and managers (n=5) participated in the study. The study established the domains of effective implementation and areas of challenges with discrepancy between the expected level of strategy implementation and availability of sufficient human and fiscal resources to enhance effective strategy implementation. The factors that impeded the effective implementation of the road safety strategy towards reducing accidents and road fatalities on the N1 in the Limpopo Province included the inadequate allocation and distribution of traffic officers in areas with a high probability of accidents, delayed recruitment of sufficient traffic law enforcement officers and unavailability of required budgeted funds for procurement of state of the art physical equipment to monitor the speed and magnitude of traffic flows and real-time surveillance and capture of road safety transgressions. The findings revealed that there is a considerable need for traffic law enforcement managers to collaborate with behavioural professionals and the police to ascertain effective behavioural change mechanisms to encourage road safety compliance. However, recruitment and constant re-training of traffic law enforcement officers on best practice strategies for traffic law enforcement could be useful to ensure the effective implementation of the road safety strategy; thereby contributing towards the reduction of accidents and road fatalities on the N1 in the Limpopo Province.

Four trap crops were tested for their ability to intercept stinkbugs (Heteroptera pentatomidae) in a cucurbit field crop at Waterpoort, Limpopo Province. The experimental trap crops were: Sunnhemp (Crotolaria juncea), okra (Abelmoschus esculentum), mustard mixture (Brassica hirta and Brassica juncea) and cowpea (Vigna unguiculata). The surveys were based on visual counts of stinkbugs from all the trap crops. Stinkbugs were collected from trap crops in a field crop trial of cantaloupe (Cucumis melo). The correlation between Brassica hirta and Brassica juncea with other trap crops had a great variance. The repeated B. hirta and B. juncea inner row experiment in 2012 interestingly lured the green stinkbug (Nezara viridula) into the cantaloupe field. Amongst the entire trap crops, stinkbugs recovered from Brassica hirta and Bassica juncea, exceeded the average of the other three trap crops. The number of adult N. viridula captured had significantly increased in March 2012 and started to drop on the B. hirta and B. juncea mixture in the first week of April. During this increase, the crops were at the seeding stage. The perimeter trap-cropping system practiced for all four trap crops varied in the attraction of stinkbugs along the perimeter of the field and inner row. B. hirta and B. juncea attracted a high number of N. viridula along the perimeter but fewer in the inner row. The B. hirta and B. juncea recorded the highest number of N. viridula in the inner rows and outer rows, compared to the other four trap crops, followed by V. ungiuculata. This study has demonstrated a significant potential of using trap crops as biological alternative for managing stinkbug pests in cucurbit crops. / Agriculture and  Animal Health / M. Sc.

The Matimba and soon to be completed Medupi power stations located in close proximity to the town of Lephalale are a cause for environmental concern due to the known effects that coal combustion has on air, soil and water quality. The Medupi power station is currently being constructed, while the Matimba power station may have already negatively altered the water quality of the rivers especially those downwind of the power stations. The Lephalala (perennial river, upwind), the Mokolo (perennial river, upwind) and Matlabas (seasonal river, downwind) Rivers were selected due to the locations relative to the power stations. The concentrations and flux of cations and sulphate ions within the rivers in the Waterberg District Municipality were investigated for any seasonal or annual patterns using monthly data from a single sampling station along each river. Data for the concentrations of sodium, potassium, magnesium, calcium, ammonium and sulphate were analysed in conjunction with river discharge, rainfall and ambient temperature data available for each hydrological year from 1999 to 2010. The data were converted to seasonal and annual values in order to determine the influence of the quality and quantity of coal combusted as well as climatic variables (rainfall, temperature and discharge) on ion fluxes measured. Sodium was the dominant cation in all rivers, reaching a maximum concentration of 0.0015 mol.ℓ-1 (in 2007), 0.0007 mol.ℓ-1 (in 2007) and 0.0006 mol.ℓ-1 (in 2001) in the Lephalala, Mokolo and Matlabas Rivers, respectively. Other cation concentrations were four times lower in the Lephalala and Mokolo Rivers, while they were eight times lower in the Matlabas Rivers. Sulphate concentrations were approximately nine, five and 15 times lower than the cation concentrations measured within the Lephalala, Mokolo and Matlabas Rivers, respectively. The mean summed cation flux was highest in the Lephalala River (0.0015 ± 0.0010 Eq.ℓ-1), which was approximately 1.7 and 2.1 times higher than summed cation fluxes measured in the Mokolo (0.0009 ± 0.0002 Eq.ℓ-1) and Matlabas (0.0007 ± 0.0006 Eq.ℓ-1) Rivers. Cation fluxes were highest during the rainfall season (summer and spring) in the river closest to the Matimba power station (Mokolo Rivers) while summed cation flux in the Lephalala and Mokolo Rivers (located further away from the power station) showed no specific seasonality. It was, however, noted that the cation fluxes during spring and winter were elevated for both rivers, possibly indicating

Thesis (M.Sc. Agriculture (Agricultural Economics)) -- University of Limpopo, 2018 / The Land Restitution Programme was designed to assist farmers through support for infrastructure, marketing, finance and extension services. This initiative was intended to support job creation, food security and support agricultural growth. Nevertheless, poverty and food insecurity have profound implications for health and welfare. However, household dietary diversity score has long been recognized by nutritionists as a key element of high-quality diets. This study examined the effects of the land restitution on households’ food security in Waterberg district. The objectives of this study were to profile households’ socioeconomic/ demographic characteristics, assess the food security status of land restitution beneficiaries and non-beneficiaries, examine the effects of Land Restitution Programme on food security and investigate the challenges faced by smallholder farmers in accessing land and other inputs for agricultural purposes in Waterberg district. Primary data was collected from 110 smallholder farmers using purposive and random sampling techniques. Dietary diversity score was used to assess the food security status of land restitution beneficiaries and non-beneficiaries while logistic regression model was used to examine the effect of Land Restitution Programme on their food security status. The results of dietary diversity score revealed that 70% of the households were food secure while 30% of the households are food insecure. The age of the household head, access to the market and land size were found to be positively significant at 10% level while beneficiary status was found to be positively related to food security status and significant at 5% level. Variables which were found positively significant at 1% level are gender of the household head, off-farm income and access to credit. Problems affecting households differs from lack of access to credit facilities to lack of grazing land. Based on the findings the study recommends prioritisation of women agricultural projects; diversification of income; provision of smallholder credit facilities in rural areas and provision land to farmers so that they increase their production which give them an advantage to become food secure. Key words: Dietary diversity, logit model, food security and Land restitution.
