Fertility intention and choice of method of contraception among young women (20-24 years old) in KwaZulu-Natal, South Africa

This Dissertation is submitted in partial fulfilment of the Master of Arts in Demography and Population Studies at the University of the Witwatersrand, 2017Background: In South Africa, poor choice of contraception method or contraceptive failure has been noted as one of the key contributors to high rates of unwanted pregnancy and HIV/AIDS. Contraceptive use is highly correlated with pregnancy and fertility intention. While research knows the role of contraceptive use in delaying conception and/or childbearing, what remains unknown is an understanding of whether the methods of contraception used by young women match their fertility intentions. The objective of this study is to determine the relationship between fertility intention and method of contraception among young women (20-24 years old) South Africa. Methods: This study provides a secondary data analysis on cross-sectional data from the 19992002 Transition to Adulthood in the Context of HIV/AIDS survey. Given that the survey involved two waves of data collection in 1999 and 2002, the two respective datasets are pooled together to achieve a representative sample of 8 370 adolescents aged 14 – 24. However, because the population of interest is young women, further sample restrictions are performed and a weighted sample of 1,020 sexually active young women aged 20-24 years old is attained. A multinomial regression is adopted for this study because the outcome variable-method of contraceptioncomprises of three categories: (1) modern method (2) traditional (3) no method. As such, in establishing the relationship between fertility intention and method of contraception, three levels of analysis are carried out. Firstly, is a univariate analysis of the variables in the study, followed by a bivariate analysis using Chi2 to examine the association between predictor variables and method of contraception. Finally, a multivariate analysis producing the adjusted and unadjusted associations is conducted to examine whether a statistical relationship exists between fertility intention and method of contraception. Results: Of the 1,020 sexually active young women 20-24 years old years old in the sample, 77.8% do not use any method of contraception while 13.9% make use of modern methods and only 8.1% use traditional methods of contraception. There was no significant association found between fertility intention and method of contraception. Among young women that intend to have three or more children in their lifetime compared to those that intend to have 1-2 children, the relative risk of using a modern method of contraception compared to not using any method of contraception is expected to decrease by a factor of 0.620 (95% CI=0.351,1.095; P>0.05). However, positive associations were found between relationship status and method of contraception as well as between place of residence and method of contraception. Among young women that have steady partners compared to those that are single/not in a relationship, the relative risk of using a traditional method of contraception compared to not using any method is expected to decrease by a factor of 0.274 (95% CI=0.122, 0.617; P<0.05). Furthermore, among young women living in rural areas compared to those in urban areas the relative risk of using a modern method of contraception compared to not using any method is expected to decrease by a factor of 0.499 (95% CI=0.300, 0.831; P<0.05). Conclusion: This study has demonstrated that fertility intention cannot be used as the sole predictor of the choice of contraception used by young women. Rather, there are prevailing and contextual demographic and socio-economic factors that intervene this relationship and influence women’s adoption of any method of contraception. Notably, the limited access to healthcare centres; ambivalent feelings about pregnancy as well as misconceptions and perceived side effects of contraception influence the poor use of modern methods of contraception. To address the high rate of unwanted pregnancy among youth in South Africa, it is advisable that policies and programmes assist young women to become decisive about their fertility intentions and provide them with the necessary support and resources to access contraceptive methods that will assist them in achieving their fertility goals.XL201

Spatial assessment of environmental fate of Acid Mine Drainage (AMD) contaminants in engineered wetlands along the Varkenslaagte canal

A dissertation is submitted as MSc research project in partial fulfilment of the requirements for the degree of Master of Science in the School of Geography, Archaeology and Environmental Studies. July 2016.A major cause of environmental problems, in the vicinity of mine tailings in and around Johannesburg, is Acid Mine Drainage (AMD). In most research, engineered wetlands are used to ameliorate AMD with the use of vegetation to remove or extract heavy metals from the soil (i.e. phytoremediation). Phytoremediation has been defined as a technology that uses plants to extract or immobilize contaminants in soils and waters (Torresdey, 2007). The aim of this study was to assess and quantify the mass pool size of contaminants (macronutrients, micronutrients, non-essential trace elements) within and between a subset of paddocks from various compartments including sediments, aboveground biomass (shoots –stems and leaves), and belowground biomass (roots and rhizomes) of the two wetland plant species present (P. australis and S. corymbosus ). Analyses were done on the wetland paddocks in situ and ex situ applying different methods, water sample metal cations were analysed by ICP-MS and the major anion analysis by chromatography and Ion Chromatography (IC). The sediment and plant samples were subject to X-Ray fluorescence (XRF) analyses of major elements and trace elements. Although analysis was undertaken for numerous trace and metal elements, only a few macronutrients, micronutrients, and non-essential elements with significant importance to the West Wits Mining Operation were selected for this study. The stream water test strips yielded poor results for this extremely contaminated plume receiving environment this suggests that in this system they are not a useful substitute for conventional laboratory analyses. Of the elements tested, only S showed significant differences in concentrations in plants between paddocks, with the highest concentrations and mass in the downstream paddocks ww6 and ww7. These paddocks also had the greatest masses of S in sediments, and water concentrations were also highest in paddocks ww4, ww6 and ww7. P. australis accumulated highest elemental mass than S. corymbosus, with the highest Zn mass of 93%. P. australis accumulated double the mass of U, Cu, Cl, Ca. In both plants, the roots consistently had highest elemental concentration with sequence often as follows roots> shoots> rhizomes. Sediment element mass accumulation of most tested elements significantly increased with depth, except for Zn and U, which decreased with depth. There are few significant differences in the mass distribution of the elements analysed between paddocks, which is assumed to reflect either the heterogeneity in the underlying sediments following construction of the wetlands, or lateral inputs into the system as seepage from other TSFs. Key words: AMD, Wetland, Varkenslaagte Canal, West Wits Mining Operation, metals, sediment, S. corymbosus, P. australis, ICP-MS, XRF.LG201

Indigenous plants in the Limpopo province : potential for their commercial beverage production

South Africa has over 19 500 different indigenous plant species. Most of these are of ethnobotanical significance and are still used by local rural communities as medicine, food and for making beverages. The relatively little research that has been conducted on indigenous plant species has focused mainly on their medicinal potential. However, in view of the rapidly growing size of the global and local beverage industry and their constant search for new products, beverage-making indigenous plant species may have commercial development potential. To date, no detailed studies have been conducted on these plants, especially in the species-rich Limpopo province. The aim of this study was, therefore to evaluate the potential of indigenous plants for commercial beverage production. In order to achieve this, a survey was conducted in the Limpopo province to identify beverage-making plants and to document beverage preparation methods. Selected beverages were analysed and evaluated for their nutrient and sensory characteristics and a market product acceptability survey was conducted to identify those beverages with the greatest potential for development. Sixty three different beverage-plant species were identified in three study areas within the Limpopo province. These were used for the preparation of teas, fruit juices and alcoholic beverages. Plants that received further research attention were selected on the basis of their status as indigenous plants, frequency of use, nature of harvesting methods and availability. Some of the selected beverages were found to be rich in nutrients, especially with respect to vitamin C and mineral content. Furthermore, sensory analyses and market surveys indicated that four species, namely, Doyvalis caffra, Garcinia livingstonei, Grewia flavescens and Englerophytum magalismontanum have potential for further development for the beverage industry while Athrixia phylicoides has commercialisation potential as a herbal tea. However, further research is required to improve and refine preparation methods and to ensure compliance with quality standards. The availability of sufficient plant material for the industry must also be ensured. This research has indicated that South African indigenous plants have untapped market potential for the beverage industry which, if developed sustainably, could contribute to economic growth of the rural parts of South Africa.Environmental SciencesD.

The role of urban vegetable production in Jos (Nigeria) as a source of livelihood

Many cities of developing countries experience widespread poverty due to accelerated migration of people from rural to urban areas as well as high population growth rates. The city of Jos in Plateau State is experiencing rapid population growth as well, with the attendant problems of food insecurity, insufficient income, unemployment and environmental degradation. This study assessed the role that urban vegetable production plays in providing a source of livelihood to small-scale farmers in Jos. The farmers were registered with the third Fadama Project in Nigeria. Such projects derive their name from the native Hausa word ‘fadama’ which means irrigable lands on flood-prone and low-lying plains. Forty percent (40%) of urban vegetable farmers were randomly selected to have a sample size of 94 participants. A mixed method approach was used and this involved questionnaire-administered interviews. The primary data obtained were transcribed and subjected to ANOVA and t-test analysis. From the results obtained, most of the vegetables farm plots are located predominantly in the southern part of the study area. Results indicated that vegetable farming is playing an important role in providing 84% part-time and 5% full-time employment opportunities as well as reducing food insecurity among the study participants. In addition, most farmers achieved an income of more than the minimum wage of ₦30, 000 (US$ 72. 24) as approved by the Nigerian Government. The results also showed that lack of credit facilities, seasonal variations and the high cost of farm inputs and equipment are the most serious problems faced by participants. Other challenges associated with small-scale urban farming entailed the negative environmental impacts that may lead to the decline of environmental quality, thus undermining long term sustainability. Furthermore, there were no statistically significant differences among participants in terms of the relationship between the type of vegetables they produce, incomes generated, environmental impacts and their demographical attributes. These attributes are the age, gender, marital status, and educational background of participants. Based on these findings, and the socio-economic importance of vegetable farming in this study area, governments and financial institutions should establish better policies in order to solve the problems faced by small-scale vegetable farmers in urban areas

The Nigeria Teachers Social Studies Training Curriculum and Sustainable Development Goals: A Content Analysis

The concept of sustainable development has become a widely used construct that is incorporated into virtually all disciplines and discourses. The implementation and achievement of sustainable development goals in the management of our environmental resources cannot be realised without education especially at a formal levels. Teacher training institutions - (college of education and faculty of education in universities) are expected through their courses to engage and create awareness of sustainability issues using their training programmes. This paper therefore presents a content analysis of sustainability themes and concepts in the College of Education Social Studies curriculum in Nigeria.  This is with the ultimate goal of exploring how any noticed gaps that could inhibit the promotion of education for sustainable development through teacher training can be filled, so that the post 2015 sustainable development goals could be better achieved

Understanding the Determinants of Pro-Environmental Behavior among South Africans: Evidence from a Structural Equation Model

This paper explores the relationship between pro-environmental behaviour (PEB) and environmental awareness, knowledge, attitudes, risk perceptions and activism in South Africa. To achieve this goal, the 2010-2012 data from the International Social Survey Program "Environmental III" was analysed by means of descriptive and inferential statistics, including the employment of the structural equation model. Significant differences were found between pro-environmental behaviour and other environmental variables such as environmental concern, awareness, willingness to sacrifice, and others in terms of the educational background, place of living, ethnic identity and provinces where respondents lived. Thus, to increase PEB amongst citizens would require the introduction and support of development programmes that enhance access to more education and environmental awareness across all population groups

Household cooking fuel use patterns and determinants across Southern Africa : evidence from the demographic and health survey data

Abstract: Improving access to modern energy sources is critical to enhancing the quality of life of many people in developing countries. In southern Africa, the majority of rural and poor urban households are dependent on solid fuels to meet their cooking needs. This has adverse effects on health, productivity, and environmental sustainability. To date, there is scarce information in the literature on household cooking fuel patterns and choice determinants across the southern African region. Using household fuel data from the Demographic and Health Survey (DHS), this study investigated cooking fuel types and the determinants of their choice by households in selected countries in sub-Saharan Africa. The data on household cooking energy were subjected to descriptive and inferential statistics. Results show that 25% of sampled households in all seven countries have access to electricity, while 66% rely on biomass for cooking. Chi-Square analyses revealed a statistically significant relationship between place of residence and type of cooking fuel, and between access to electricity and type of cooking fuel. Results from multiple regression analysis showed that socio-demographic factors such as access to electricity, household size, level of education, and wealth index have a positive influence on the type of cooking fuel used in this region. However, access to electricity does not imply that households will negate the use of traditional fuels. These results have implications for household air pollution, health, policy and environmental sustainability. It is recommended that energy interventions in this region need to consider demand factors and have to be less supply driven, advocating for continued use of multiple fuels from a suite of options
