Impact of mining on agriculture and socio-economic aspects in the rural communities of Greater Tubatse Local Municipality

Tsebe, Mapuru Rachel 07 1900 (has links)
The majority of people in the mining areas in Limpopo, South Africa, depend on agriculture to sustain their livelihoods; however, the mines have also become important because they create better employment opportunities. The purpose of the study was to analyse the impact of mining on agriculture and socio-economic aspects in the rural communities of the Greater Tubatse Local Municipality. The objectives were to profile the socio-demographic characteristics of the community members surrounding a chrome mine; to determine the impact of mining activities on agricultural production (crop and livestock production); to determine factors influencing farmers’ perceived impact of mining activities on agricultural production; and to ascertain the socio-economic (natural capital, financial capital, social capital, human capital, physical capital) impact of mining activities on the local communities. A quantitative research approach was used to conduct the study using a survey design. Six villages surrounding a chrome mine in the Greater Tubatse Local Municipality in Limpopo participated in the study. Stratified and random sampling approaches were used to select participants from each village to constitute a sample of 347. A total of 347 survey questionnaires were administered through face-to-face interviews but only 309 were correctly and fully completed. SPSS version 24 was used to analyse the data. The data were analysed using descriptive statistics, the ordered logistic regression model, Wilcoxon signed ranks test and binomial test. The majority (50.8%) of the respondents were male. Sepedi was the most spoken language (97.7%). Most (63.3%) of the respondents were in the age range of 18-30, and 76.4% were single in terms of marital status. A large proportion of the respondents (70.6%) could read and write because they had secondary education. Land ownership findings show that more than half (58.1%) of the respondents had farm plot sizes between 4.6 and 10.5 ha. Average farm plot size was 4.1 ha, and only a few (1.3%) of the plots were above 9 ha. The average family size was about 7 people (actual 6.7). A large proportion (77.7%) of the respondents were dependent on government social grants (pensioners, disability and orphans) as the main source of income. Regarding the impact of mines on agriculture, the study found that in general, the mines did not have a negative impact on the production of livestock and crops, except for donkeys and groundnuts, which were negatively affected. In addition, the findings also show that a large proportion (92.6%) of the respondents lost their agricultural land (mainly grazing land) because of increased mining activities, although the loss of land did not affect production. With regard to the socioeconomic impact of mining activities on the surrounding communities, the study found that the mines had a negative impact on natural capital, physical capital, financial capital and social capital. However, the impact on human capital was positive. It is recommended that mining companies in the study area provide the necessary support to improve the socioeconomic status of the rural communities surrounding the mines in Greater Tubatse Local Municipality. / Agriculture, Animal Health and Human Ecology / M.

Integrating sustainable manufacturing assessment into decision making for a production work cell

Zhang, Hao 16 May 2012 (has links)
Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated sustainable production decision making, where engineers are required to concurrently consider economic, environmental, and social impacts. An approach is developed to assess broader sustainability impacts by conducting economic assessment, environmental impact assessment, and social impact assessment at the work cell level. The results from the assessments are then integrated into a sustainable manufacturing assessment framework, along with a modified weighting method based on pairwise comparison and an outranking decision making method. The approach is illustrated for a representative machining work cell producing stainless steel knives. Economic, environmental, and social impact results are compared for three production scenarios by applying the sustainable manufacturing assessment framework. Sensitivity analysis is conducted to study the robustness of the results. For future research, it is desired that a tool which integrates manufacturing information system information and the sustainable manufacturing assessment approach can be built to assist production engineers in considering sustainability performance when making decisions. / Graduation date: 2012

An assessment of the environmental compliance monitoring capacity of the Department of Minerals and Energy, Eastern Cape

Watkins, Deidre Ann January 2009 (has links)
One of the greatest challenges facing the world today is integrating industrial activities such as mining with environmental integrity and social concerns. Monitoring is fundamental to environmental management, both to assess the adherence to standards and to allow environmental managers to learn from practical experiences. However, a problem arises when the regulatory authorities cannot keep up with their mandate of enforcement and compliance monitoring. This research examined how the Department of Minerals and Energy (DME) implements the concept of sustainable development in the mining sector of the Eastern Cape (EC) and, more specifically, the extent to which the Mine Environmental Management (MEM) section is able to effectively monitor compliance of mining operations with environmental legislation. This was the first systematic compilation of statistical data for the DME, and presents the first study in the EC regional office in terms of environmental sustainability. Results indicate that there has been a sustained increase in mining activity over the past three years, possibly as a result of the boom in the construction industry and the accelerated road maintenance and improvement programmes in the Eastern Cape. Mining applications received by the DME have increased by 47% from 2006 to 2007 (January-May) and by a further 100% from 2007 to 2008. In addition to the increasing number of mining concerns being established, 98 mining concerns will need to apply for the conversion of their old order rights to new order rights by the 1st May 2009. Mining in the province is predominantly small scale with mining permits (mined areas less than 1.5Ha) making up 52.3% of all applications, with larger mining concerns contributing 29.3% and prospecting contributing the remaining 18.4%. In terms of compliance inspections, the EC regional office is required to conduct 120 environmental compliance inspections annually in terms of contributing to sustainable development. The MEM section exceeded this target since 2003. However, when the number of operational mines is considered, 120 inspections per year equates to one mine being visited, on average once every four years (based on 2008 data). Based on projected figures (number of compliance audits and number of operational mines) for 2009, the DME’s target of 150 inspections for 2009/10 combined with the limited staff D. Watkins – MBA Dissertation 2008 capacity will, at best, mean that mines would be inspected once in seven years. However, the target of 150 inspections will not actually even cover the expected number of EMP evaluation inspections. This has serious implications in terms of regulating the compliance of the mining concerns with their EMPR’s. The low level of compliance monitoring can be directly related to staff capacity and logistics problems at the regional office as well as provincial targets being based on staff capacity rather than the number of operational mines. Thus, considering potential environmental damage associated with mining operations and the capacity constraints of the MEM to conduct frequent compliance audits, it is likely that mining operations will have negative implications for sustainable development in the region. Currently there are many challenges facing the DME in terms of contributing positively to sustainability in the mining sector and there is a need to base future actions on the idea of continuous improvement and ultimately progress.

The identification and evaluation of key sustainable development indicators and the development of a conceptual decision-making model for capital investment within Gold Fields Limited (GFL)

Jacobs, Phillip A H January 2010 (has links)
The current trends in sustainable development (SO) were examined in this study, which brought about the realisation that SO has become a business imperative. Mining, which is a highly impacting industry, is faced with the dilemma of implementing the principles of SO despite the realisation that its activities are severely limited by· the finite nature of the resource it is capitalising on. This reality, however, does not detract from the non-negotiable requirement for the industry to meet the increasing pressures to act responsibly towards the environment and the community in which it operates. Gold Fields has stepped up to the plate and has already taken several steps to achieve this end. These include the adoption of SO in its Vision, Values and strategies and the development and implementation of a SO framework to ensure the integration of the principles of SO into the business. Furthermore, Gold Fields has also entered into voluntary activities that further cement the commitment the company has towards so. These other initiatives include, inter alia, its International Council on Mining and Metals membership, UN Global Compact participation, becoming a signatory to the cyanide code, IS014001, and so on. This study focussed on several indicator categories and the identification of a set of supporting sustainable development indicators (SOls) for each, which included environmental, social, economic, technological, and ethics, legal and corporate governance (not in order of priority). These indicators were assessed by a carefully selected group of respondents whose collective wisdom and expertise were used to identify and weight supporting SOls for each of the indicator categories. These supporting SOls were in turn used to develop a model that is able to assist in the business's decision making processes when capital investment is being considered . A water treatment project that is currently being considered by Gold Fields was utilised to demonstrate how the decision making model can be applied to two different scenarios. The result clearly and successfully demonstrated that by proactively taking environmental, economic, social, technological, and ethics, legal and corporate governance considerations into account, a gold mining company is able to increase the level of SO of a capital investment project.
