Commercial forest species discrimination and mapping using cost effective multispectral remote sensing in midlands region of KwaZulu-Natal province, South Africa.

Masters Degree. University of KwaZulu-Natal, Pietermaritzburg, 2018.Discriminating forest species is critical for generating accurate and reliable information necessary for sustainable management and monitoring of forests. Remote sensing has recently become a valuable source of information in commercial forest management. Specifically, high spatial resolution sensors have increasingly become popular in forests mapping and management. However, the utility of such sensors is costly and have limited spatial coverage, necessitating investigation of cost effective, timely and readily available new generation sensors characterized by larger swath width useful for regional mapping. Therefore, this study sought to discriminate and map commercial forest species (i.e. E. dunii, E.grandis, E.mix, A.mearnsii, P.taedea and P.tecunumanii, P.elliotte) using cost effective multispectral sensors. The first objective of this study was to evaluate the utility of freely available Landsat 8 Operational Land Imager (OLI) in mapping commercial forest species. Using Partial Least Square Discriminant Analysis algorithm, results showed that Landsat 8 OLI and pan-sharpened version of Landsat 8 OLI image achieved an overall classification accuracy of 79 and 77.8%, respectively, while WorldView-2 used as a benchmark image, obtained 86.5%. Despite low spatial of resolution 30 m, result show that Landsat 8 OLI was reliable in discriminating forest species with reasonable and acceptable accuracy. This freely available imagery provides cheaper and accessible alternative that covers larger swath-width, necessary for regional and local forests assessment and management. The second objective was to examine the effectiveness of Sentinel-1 and 2 for commercial forest species mapping. With the use of Linear Discriminant Analysis, results showed an overall accuracy of 84% when using Sentinel 2 raw image as a standalone data. However, when Sentinel 2 was fused with Sentinel’s 1 Synthetic Aperture Radar (SAR) data, the overall accuracy increased to 88% using Vertical transmit/Horizontal receive (VH) polarization and 87% with Vertical transmit/Vertical receive (VV) polarization datasets. The utility of SAR data demonstrates capability for complementing Sentinel-2 multispectral imagery in forest species mapping and management. Overall, newly generated and readily available sensors demonstrated capability to accurately provide reliable information critical for mapping and monitoring of commercial forest species at local and regional scales

The cultural politics of adaptation : fools and the politics of gender

The shifts in the priorities of literary and cultural theory and criticism were already underway in the South African academy by the end of the 1980s, with the gathering momentum of the mass political movement reaching its apotheosis with the release of Nelson Mandela from prison in 1990. Whereas creative literary and cultural expression has often lagged behind advances in theory, there was nevertheless a steady acknowledgement of the necessity for a corresponding shift in the discursive character of the creative arts, even if the material conditions on the ground remained largely unchanged. Ramadan Suleman’s film Fools, which appeared in 1997 as an adaptation of Njabulo Ndebele’s 1983 novella by the same title, entered the fray with its argument for a new or, as it were, broader consciousness of the deeper, more complex legacy of ‘sexual violence’. This legacy included the weak ‘place of women in the everyday life of the township’ (Suleman 1995: 1), and indeed in the very idea of ‘the everyday’ that some in literary and cultural circles sought to inscribe. This article provides an assessment of the nature and extent of the film’s intervention in the context of the systematic breakdown of the old certainties of race, identity and nation post-apartheid, together with the literary-critical cultures and apparatuses that presided over their coherences and raptures. I take as my starting point Robert Stam and Louise Spence’s (1983: 3) assertion that ‘[a]though […] those questions bearing on the cinematic industry, its processes of production, distribution and exhibition’ – in short, questions bearing on ‘the contextual’ – are of ‘crucial importance’, they need to be tempered with those bearing on the ‘textual and intertextual’ (emphasis in original). Fools is a film that enters the textual and contextual terrain of Ndebele’s novella, but in doing so contests its textuality by shifting its narrative ground and voice

Factors facilitating pest infestation in two low-income urban areas of Cape Town, South Africa : an urban health observation study

High pest burdens in low-income urban areas pose a significant public health threat to residents due to pest-induced diseases and other negative health consequences. Furthermore, pests can also be a source of nuisance and social stigma. To ward off pests and the problems they are associated with, many residents of socioeconomically disadvantaged urban areas frequently use pesticides, including highly toxic illegal pesticides. Inappropriate and indiscriminate use of pesticide is a concern since pesticide exposures can put residents, especially children, at risk for negative health effects. While pesticide use and exposures are common in many low socioeconomic urban areas globally, pesticide-induced adverse health effects are of particular concern in developing countries, such as South Africa, where pesticide regulations and enforcement thereof is often lacking. Following the alarming rise in number of children hospitalized with pesticide poisoning in the Cape Town surrounds, researchers at the University of Cape Town conducted a study whose aim was to identify common in-home pests, pesticide use and exposure patterns, and pesticide risk perceptions in Khayelitsha and Philippi, two low socioeconomic communities of Cape Town. This study was part of the larger project and was focused on investigating factors that contribute to pest infestation in low socioeconomic urban areas. An analysis of qualitative data that examined factors in housing, environment and practices and pest control behaviours of poor urban residents that facilitate pest infestation is presented in this mini-dissertation. The protocol (Part A) describes the study population and the methods used to collect and analyse the data. The structured literature review (Part B) describes the double health burden from pests and pesticide exposure faced by low-income urban residents. It also discusses the poverty-related factors that contribute to pest infestations in impoverished urban areas. Lastly, it critically evaluates research on alternative non-toxic pest control methods relevant for low socioeconomic urban communities

The role of microfinance institutions on entrepreneurship development: the case of Swaziland

Thesis (M.M. (Finance & Investment)--University of the Witwatersrand, Faculty of Commerce, Law and Management, Wits Business School, 2016.The primary aim of the microfinance initiative is to eradicate poverty especially in developing countries. This is possible through the provision of micro-loans, microsavings and insurance to previously disadvantaged communities. Entrepreneurship is the role that individuals undertake to create, an organization, product from an idea to implementation. With high unemployment and poverty levels, Swaziland is engaging the Microfinance Institutions and entrepreneurship to help drive employment, and poverty alleviation. The study assessed several issues: Does microfinance contribute to Improvements in the economic welfare of borrowers’ households, enterprise growth, diversification or stability? Do entrepreneur development programs; like training workshops have an impact on participant’s attitude and behavior in conducting entrepreneurship activities. Is there a relationship between microfinance institution growth and entrepreneurship development? Results indicated that microfinance institutions were still sorely focusing on providing credit and credit facilities, which meant that it had positive effects on capital assets but not the overall welfare of entrepreneurs. The behaviors that programs influenced were also in relation to credit, and not other aspects of entrepreneurship like innovation and technology. This meant that there’s a gap in the effect of microfinance institutions on entrepreneurship growth as indicated chisquare was significant at 9.43 indicating no effect on the sampled population. Therefore it is important that Microfinance institutions focus on the primary objective of developmental finance. They need to prioritize training programs that will cultivate a culture of building sound businesses, with proper risk management, and are willing to adapt to change. As currently the key focus seems to be on credit facilitation which could be profit driven?GR201

Green sourcing strategy challenges faced by Automotive Component Manufacturers in Durban, South Africa.

Masters Degree. University of KwaZulu-Natal, Durban, 2019.There is a growing need to protect the environment mainly because a clean environment is of essence for healthy living. One of the means by which automotive component manufacturers (ACMs) may protect the environment is by implementing green supply chains. Demand for motor vehicles has been intensified by continued increase in the world’s overall population. Original equipment manufacturers (OEMs) are producing more vehicles to meet demand and ACMs are in turn required to produce more component parts to meet OEMs’ demand. The significance of making sustainable sourcing strategy decisions cannot be overstressed. This is because sourcing is the backbone of any organisation, with its main aim being to procure critical components at the lowest possible cost from consistent and reliable suppliers at the best quality. The adoption of Kraljic’s (1983) purchasing portfolio model is presumed to be used as a sourcing strategy. The main aim of this research is to understand how ACMs incorporate green elements in sourcing and to identify drivers and barriers to the implementation of green supply chain. This cross-sectional study made use of mixed method and data were collected using personally administered questionnaires to purchasing and logistics employees as well as managers in ACMs in Prospecton, Durban. Qualitative and quantitative data was analysed using the Statistical Package for the Social Sciences (SPSS) version 23 and Nvivo 11, respectively. Participation in the study was voluntary and anonymity of participants was maintained. Green sourcing is not yet a priority to ACMs and those that are practicing it confirmed that greening requirements have influenced sourcing. Kraljic’s (1983) model is used extensively by ACMs in Durban and the model is considered crucial when conducting sourcing. Recommendations based on findings include; a thorough understanding of the consequences of the deteriorating environment and contributions ACMs make, ACMs providing trainings and courses to educate employees on green sourcing and its significance, mitigating barriers to implementing green sourcing by involving suppliers, customers and government when conducting sourcing

A comparative study of multiculturalism in South Africa and Canada: evaluating successes and failures.

The purpose of this study was to evaluate the successes and failures of multiculturalism in South Africa and Canada through the lens of critical multiculturalism as its theoretical frame. As Canada is widely-acknowledged as having one of the best multiculturalism policy and implementation programmes in the world, this study aimed to draw lessons from the Canadian model of multiculturalism in order to make recommendations to improve multicultural practices in South Africa. It is worth noting that multiculturalism in Canada is not perfect as government still struggles to implement inclusive and reconciliatory programmes for the previously colonised Indigenous communities. This study used a qualitative thematic analysis to enable a comparison of multiculturalism in these two countries. The findings of this study suggest that having a comprehensive multiculturalism policy is fundamental to ensure that aspirations of a socially cohesive multiculturalism are not merely philosophical, but are formulated into government policies, with guidelines for implementation through the guidance of critical multiculturalism theory. The findings of this study also suggest that the persistent racialised socio-economic inequalities in South Africa continue to undermine multiculturalism and nation-building efforts.Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 202

Social entrepreneurship as a pragmatic concept for social work professionals' management competence in South Africa

Thesis submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, in fulfilment of the requirements for the degree of Doctor of Philosophy, PhD (Management)The South African Government has entrusted Social Work Professionals (SWP’s) with the responsibility of humanizing the lives of the most vulnerable groups in society. SWP’s are scrupulously trained to rehabilitate and heal the ailing community, but nowadays they are inadvertently incapacitated because their role has grown far beyond its original skill-base whilst their educational grooming and the legislation governing their role has remained stagnant. Furthermore, the Non Governmental Organisations (NGOs) within which they operate are unsustainable and many of them struggle for survival. The prevailing socio-economic environment imposes various demands on both the SWP profession and the non-profit sector, forcing them to provide for their survival by performing commercial duties that they are not trained to perform. This practice has resulted in a disjuncture in the roles of SWP’s and a brain-drain of professionals out of the sector. The study was split into two separate albeit related components employing a combination of qualitative methods and techniques to thoroughly investigate the source of this disjuncture and establish viable methods to address it. The first phase was designed to understand the history of social work in South Africa spanning two political dispensations, assess the legislated role that SWP’s should perform against the current role they are performing, in order to understand and explain the discrepancy in their role. Thereafter the second phase was conducted as a follow-up to explore how the concept of Social Entrepreneurship in conjunction with comprehensive management proficiency could provide possibilities of addressing and improving the shortcomings arising in the role of the SWP. ii The first phase documented that SWP’s are currently struggling in practice, with inadequate resources and lack of enterprise and management proficiency to fully facilitate their mandate. This deficiency suggested a shift in their role that is different from their usual rehabilitating role. Social Policy Frameworks were identified as the possible hindrance for the current lack of enterprising in the social sector, followed by socio-economic pressures and insufficient education and training of SWP’s. A paradigm shift to acknowledge and qualify the growth in the role of an SWP academically and legislatively was recommended, followed by relevant intellectual construction of knowledge. The second phase of the study acknowledged that Social Entrepreneurship is a fairly new concept in academic circles. In addition, most reviewed literature on Social Entrepreneurship suggested that the African landscape was either not fully understood by the authors or not yet catered for since most of the solutions were not fully commensurate with problems experienced in (South) Africa. Therefore, the researcher approached available scholars globally with primary data depicting real problems that are experienced on the ground and which seemed to challenge their presented solutions from the reviewed literature. This process systematically examined the concept of Social Entrepreneurship, accentuating how a different set of resource combinations of its aspects customized for the South African socio-economic environment could open up a new window of knowledge to enhance the impending social transformation, notwithstanding the view that further research for African needs was strongly encouraged. Findings from the first phase strongly suggested specialisation in the profession of an SWP in the short term and the development of a new cadre of enterprising SWP’s in the longer term. The second phase’s findings validated the suggestion from the first phase to split the role of an SWP, introduce entrepreneurial and management competence designed for social benefit as a new and special role, and develop a new cadre of professionals over time who will specialise in the new competence. iii Findings from both phases of the study have led to the conclusion that the role of an SWP has shifted and grown far beyond its original skill-base. This conclusion has notable policy implications for legislation governing SWP’s. Whilst this study has acknowledged and qualified the growth in the role of an SWP academically as entrepreneurial and management deficiency, to complete the acknowledgement, this growth has to be recognised legislatively within the policy frameworks. Specialisation in the profession of social work would also need to be legislated to enable academia to provide intellectual leadership on the new role, define research needs, develop a new curriculum, then recruit and develop a new cadre of enterprising SWP’s. These findings lead to a further conclusion that policy frameworks governing SWP’s are not entirely congruent with the prevailing socio-economic environment and might benefit from a review that underlines SWP’s’ core function, education and training that is commensurate with the needs of their role, especially the needs of the shift experienced in their role

Communities of practice in institutions of higher learning : a descriptive study of the humanities at the University of KwaZulu-Natal and the University of Zululand.

Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.Knowledge is a key resource. It enables individuals and organisations to perform through social interactions. New knowledge is created and shared that gives an organisation the edge to succeed in a highly complex and demanding world. Higher education institutions need to value and nurture the knowledge of academic staff and support and encourage social interactions that exist. One way of doing this is through the utilization of communities of practice. Communities of practice may improve performance of an organization and encourage and facilitate learning, collaboration and knowledge sharing. The purpose of this study was to establish the extent to which communities of practice are defined and utilised within higher education institutions to foster learning and facilitate the sharing of knowledge among academic staff, in order to advance the scholarship of teaching and research in the humanities at the University of KwaZulu-Natal and the University of Zululand. The study intended to establish how communities of practice were understood, the nature of communities of practice and their formation, factors that support or inhibit the formation of communities of practice and the ways in which communities of practice can be cultivated and fostered within higher education institutions. Questionnaires, focus groups and semi-structured interviews were used to collect data. The study found that most academics at the University of KwaZulu-Natal and University of Zululand were involved in communities of practice and had an understanding of communities of practice. The study also established that both institutions did not have a policy on communities of practice. The major problems facing the academics at UKZN and Unizul were that they had very heavy workloads, family responsibilities, lacked support from the institution, time constraints, the absence of policy on communities of practice and organizational culture (see Table 6)

The role of integrated development planning in the integration and transformation of former apartheid townships in South Africa : a case study of Inanda, Ntuzuma and KwaMashu (INK), eThekwini Municipality (Durban).

M.T.R.P. University of KwaZulu-Natal, Durban 2013.During the Apartheid period township areas were excluded from development. Townships only contained residential land uses, and limited social services of poor quality. Such areas lacked economic activities people had to travel to the city for employment opportunities and access to better services. As a result of apartheid planning, the country was left with cities and towns that are racially divided, lack access to business and other services and have sprawling informal settlements and spread out residential areas that make cheap service delivery difficult. All the above mentioned outcomes require a new approach to address the development challenges in South Africa. This led to the formulation of Integrated development planning processes, which were adopted to contribute towards eradicating the legacy of the past by providing a framework for economic, social development, environment protection and to deal with spatial and infrastructure issues in all the municipal areas. This study presents findings on the extent in which integrated development planning initiative in eThekwini Municipality has transformed and integrated the Inanda, Ntuzuma and KwaMashu (INK) areas. Based on the findings of this research it has been revealed that integrated development planning approach has played a major role in transforming and integrating the INK area, hence there has been improvement in the social, economic and the spatial aspects of development. However it is recommended that the municipality also consider development of light industries and skills development initiatives to address social and economic issues that are a challenge for INK area
