This study assessed the use of indigenous acaricides in Tsholotsho, Zimbabwe. An observational study design plus laboratory analysis were used in this study. Data on demographic profiles and tick control practices in 21 villages was collected using a questionnaire. Seven hundred and fifty nine (n=759) ticks were collected from cattle using systematic sampling at 15 dip tanks. Marula efficacy was assessed using pregnancy, repellence and mortality tests. Farmers used several tick control remedies (physical removal, chemicals, and plant and animal extracts), some of which have potential to harm the health of the public. Marula caused significant decrease in mass among pregnant ticks (p<0.05), had a significant kill percentage (p< 0.05), and also repelled, killed and hindered egg laying. The active ingredients in marula formulations should be investigated. The extra-label use of conventional acaricide, and the use of compounds with potential to harm the public health needs to be regulated. / Environmental Sciences / M. Sc. (Agriculture)

This thesis is about the quest to build effective strategies to support the development of enterprise on the margins of the economy, to create jobs and reduce poverty. A core part of this challenge includes grappling with the role of markets in development, and of markets as a critical part of the context in which enterprise development in rural and peri-urban areas can either provide a path out of poverty – or instead serve to lock people into poverty. The thesis explores these issues by tracking the experience of the Mineworkers Development Agency (MDA) as it attempted to grapple with this challenge. MDA is the development wing of South Africa’s National Union of Mineworkers (NUM) , and was set up to create jobs and support enterprise development for communities affected by the loss of jobs on the mines. The thesis covers a fourteen-year period in MDA’s history, from its inception in 1988 until 2002. It tracks the learning process across several phases in the development of MDA’s approach. These included the development of worker co-operatives, the establishment of business service centres, value-chain work in the craft sector, and the commercialization of a juice product from the indigenous marula berry. In the process, MDA engaged with an emergent paradigm in the development sector called ‘Making Markets Work for the Poor’. Can markets really be made to work for the poor? Or even just made to work ‘better’ for the poor? Or is the process of inclusion in markets inexorably and inevitably one of making the poor work for markets? The thesis explores these issues in the context of MDA’s experience, locating this within a wider set of theoretical concerns over the role of markets in society, and the ways in which societies have protected themselves from the negative impacts of the development of market economies. It draws on wider political economy approaches to argue that markets are institutions that are socially constructed, and explores what scope there might therefore be to construct them differently. While recognising the importance of social protection, the thesis argues that there is a need to go beyond defensive strategies aimed at protecting society from markets, to identify new terms of engagement within markets to shape markets, and to harness their wealth-creating potential in ways that have different distributional consequences, as part of a long-term agenda of eradicating poverty.

Thesis (M. Sc.(Geography)) -- University of Limpopo, 2019 / Global production of Platinum Group Metals (PGMs) is dominated by South Africa due to its large economic resources base in the Bushveld Igneous Complex (BIC). PGMs are used in a wide range of high technology applications worldwide including medicinal, industrial and commercial purposes, and its contribution to the Gross Domestic Product (GDP) and creating jobs for many. In an area where mining activities dominate, there are likely to be problems that need effective environmental management approaches, which can be facilitated through legislations. Marula Platinum Mine (MPM) is located in Limpopo province BIC which has the second largest number of mining productivity in South Africa. Environmental legislations have been put in place by the South African government in order to avoid or minimise the footprints caused by PGM mining. This study looked at environmental compliance with solid waste management practices by Marula Platinum Mine (MPM) as guided by Mineral and Petroleum and Resource Development Act (MPRDA) and National Environmental Management Act (NEMA) as well as the environmental impacts of MPM in the surrounding communities. Both primary (questionnaires, field observations and key informant interviews) and secondary (NEMA, MPRDA, journals, reports, pamphlets, internet and books) data was used to address the objectives of the study. Descriptive method and Statistical Package for Social Sciences (SPSS) version 25 were used for the analysis of data. The key research results revealed that MPM was compliant with 65% and 21% partially compliant with solid waste management practices. Only 14% of information on solid waste management practices could not be accessed because MPM is still operational. MPM had also had negative footprints on the surrounding villages such as dust generation and cracks on walls and floors on houses of community members, strikes and increase in the usage of substance abuse. Recommendations of the study are that MPM should address challenges that hinder environmental compliance so as to be 100% compliant with MPRDA and NEMA regulations. MPM should also provide other mitigation measures for blasting of explosives to reduce dust generation and problems of cracks on houses of surrounding village members.
