Groundwater resource evaluation and protection in the Cape Flats, South Africa

Segun Michael Adegboyega Adelana January 2010 (has links)
<p>The analysis of geologic, hydrologic and hydrogeologic data interpreted to give the characteristics of the Cape Flats aquifer showed the quality of groundwater from the aquifer is suitable for development as a water resource. The conceptual model of the Cape Flats sand shows an unconfined sandy aquifer, grading into semi-confined conditions in some places where thick lenses of clay and peat exists. Recharge rates through the saturated zone of the Cape Flats aquifer have been determined by water table fluctuation (WTF), rainfall-recharge relationship, soil water balance and chloride mass balance methods (CMB). Recharge rates using the WTF vary considerably between wet and dry years and between locations, with a range of 17.3% to 47.5%. Values obtained from empirical rainfall-recharge equation (method 2) agree with those of the WTF. Recharge estimates from the water balance model are comparatively lower but are within the range calculated using empirical method 2 (i.e. 87 &ndash / 194 mm or 4 &ndash / 21% of MAP). These recharge rates also agree with estimates from the series of other methods applied to sites located in the north-western coast of Western Cape and are comparable to recharge rates obtained elsewhere in the world.</p>

A narrative of crystal methamphetamine: a case study of a young person’s experience of factors that leads to crystal methamphetamine use within a high-risk area in Cape Town

Jantjies, Janine Chernay January 2010 (has links)
<p>Recent research has indicated a significant increase in the crystal methamphetamine abuse in the Western Cape. The study aimed to provide an understanding of the interaction of the social and historical contexts in relation to the life experiences and perceptions of a young person residing in the Cape Flats. Primarily the study aimed to explore the factors that influenced the participant to use crystal methamphetamine. It adopted a social constructionist epistemological perspective and employed Bronfenbrenner&rsquo / s ecological systems theory as the theoretical framework. The subsystems of the ecological systems theory include the individual who is influenced by the microsystem, the mesosystem, the exosystem, the macrosystem and the chronosystem. This was a qualitative research study that&nbsp / employed an intensive case study. Data was obtained through series intensive semi-structured interviews that were approximately 40 - 70 minutes in duration. The participant is a coloured female, aged 28 years from a high-risk community in the Cape Flats. Prior to the interview process, relevant permission was obtained from the participant, which allowed the interviews to be conducted and recorded. The data was then analysed using a narrative analysis. The themes that emerged from the research findings include: childhood trauma / sexual abuse during childhood / social milieu and norms / adolescent delinquency / the cycle of abuse / understanding crystal methamphetamine use and the consequences of crystal methamphetamine use. Findings with regard to the individual factors included psychological well-being, depression and negative affectivity, feelings of hopelessness, suicidal ideations, loneliness, past abuse of legal substances, adolescence, delinquency and childhood sexual abuse. The influential factors that emerged within the microsystem were lack of family support, dysfunctional family dynamics, childhood abandonment, uninvolved parents, several custodial parents, childhood disequilibrium, parental modelling and family drug use. Further findings within the microsystem included peer influence viz. direct persuasion of drug use, peer exposure of drugs, experimentation, delinquent behaviour, gang-related involvement and peer group acceptance. The mesosystemic findings included, lack of emotional support or attachments, social support, lack of structure as well as relocating to numerous schools and homes. Findings located in the exosystem were the availability and accessibility of drugs in all the communities in which the participant lived. Findings in the macrosystem included the social environment of the individual, including the social norms of the community and the home setting as well as the norm of violence, crime and gangsterism. The information and knowledge accumulated would optimistically contribute to addressing the paucity of qualitative literature and present knowledge to&nbsp / improve intervention and prevention strategies.</p>

Multimodality and negotiation of Cape Flats identity in selected Daily Voice front pages

Matthews, Waseem January 2009 (has links)
<p>This thesis explores the social semiotic relationship of visual and verbal signs of the Daily Voice tabloid as a way to show how the social context influences meaning of the signs used in its multimodal frontpages. The Daily Voice tabloid largely uses Kaapse English/ Afrikaans as spoken by Coloureds on the Cape Flats on its frontpages rather than standard English or standard Afrikaans associated with White people. The study assumes that the meaning constructed by and through the verbal and visual signs on the Daily Voice frontpages is interdependent on the relationship the multimodal texts have with the largely Cape Flats readership. This study maintains the importance of the idea of the localisation of meaning in socio-cultural specific contexts throughout. I conclude that Kress and Van Leeuwen&rsquo / s (1996/2006) design could be extended beyond Westernised contexts and that marginalised discourses such as those unique to the Cape Flats are not static, but indeed dynamic. I also extend the appraisal theory by Martin and White (2005) to marginalised bilingual discourse and establish that Appraisal theory can be used to not only evaluate verbal discourse but also that visual discourse needs to be considered as a tool within the appraisal framework. I also conclude by suggesting a monolectal view of Kaapse English/Afrikaans discourse. That is, the meaning potential of Kaapse English/Afrikaans by Cape Flats speakers would be lost if perceived or analysed as emanating from two languages, (White) English and (White) Afrikaans. Therefore the conclusion is that the Daily Voice uses Kaapse English/Afrikaans as is used in Cape Flats socio-cultural contexts to construct meaning-making options across its frontpages.</p>

Preferential Flow Modelling in a Vadose Zone Using Macro 5.0 –Cape Flats Porous Sands.

Majola, Kwazikwakhe Alfred. January 2008 (has links)
<p><font face="Helvetica"> <p align="left">The objectives of this study were:&nbsp / To review and understand flow and transport processes in unsaturated zones. In this study, particular emphasis is placed on understanding mechanisms that cause non-uniform (preferential) flow for two casestudies, namely the Cape Flats sandy environment and the Mpumalanga Highveld fractured rock environment.&nbsp / To evaluate the adequacy of models, in particular MACRO 5.0, in simulating flow and transport in the vadose zone, by making use of two case study sites (Cape Flats and Mpumalanga Highveld). Of particular importance is the evaluation of transfer coefficients to represent fluid and solute exchange between macropores and matrix.&nbsp / To run a sensitivity analysis with MACRO 5.0 in order determine which input model parameters are the most relevant in describing the effects of preferential flow in water and solute transport.</p> </font></p>

Development of a normative model for cultural tourism on the Cape Flats

Ismail, Reedwaan January 2008 (has links)
THESIS SUBMITTED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE DOCTOR TECHNOLOGIAE ( D Tech ) (TRAVEL AND TOURISM MANAGEMENT) IN THE FACULTY OF BUSINESS AT THE CAPE PENINSULA UNIVERSITY OF TECHNOLOGY, 2008 / This study is aimed at developing and proposing a normative model for cultural tourism, which should be implemented on the Cape Flats. Normative criteria for cultural tourism were identified through a literature search, followed by an empirical study. Responses to various questions and statements were statistically analysed, interpreted and presented. Tourism stakeholders such as tour operators, travel agents, accommodation establishments and cultural tourism suppliers, including the community of the Cape Flats, can benefit from implementation of the normative model for cultural tourism. This study traces the roots of philosophy in the social sciences, provides a philosophical basis for cultural tourism, followed by a discussion of relevant national, provincial and local legislative frameworks for cultural tourism on the Cape Flats. In addition to the above, a comparative conceptual analysis of cultural tourism in The Gambia is made in order to gain a better understanding of successes and challenges that face destinations, which intend to offer cultural tourism as a tourism product. Developing a normative model for cultural tourism on the Cape Flats should seek to invite active participation from the community from inception phase until implementation. The research identifies and explains elements of model theory, discusses models that are applicable to the research area, and presents an adapted normative, input-output systems model with a feedback mechanism. The normative model proposes an implementation mechanism against various external and internal environmental factors as means to ensure sustainability of cultural offerings on the Cape Flats. The normative model proposes an approach that will facilitate employment in the tourism sector on the Cape Flats, as well as poverty alleviation initiatives as part of corporate social responsibility undertakings by tourism stakeholders. Variables identified in the normative model will assist tourism stakeholders, including the Cape Flats community, to develop cultural offerings for consumption by tourists, the cultural market and sustain cultural tourism, which should improve standards of living for people on the Cape Flats. The normative model for cultural tourism addresses the critical shortage of skills amongst tourism practitioners and offers recommendations to alleviate this shortcoming within the tourism industry. The normative criteria, which is identified in the model, addresses the fact that attention should given to improvement and provision of cultural tourism infrastructure on the Cape Flats. An objective of the normative model for cultural tourism is to facilitate the proposal of guidelines for National, Provincial and Local government policy initiatives regarding tourism and, in particular, cultural tourism on the Cape Flats. This model identifies aims and objectives of the White Paper on Sustainable Tourism Development (1996), the Cape Flats Tourism Framework (2005) and the Tourism Development Framework for the City of Cape Town (2006). Finally, the Cape Flats’ diverse community displays a host of unique cultural experiences and offerings in terms of folklore, history, experiences, food, song and a host of other activities that should be shared with tourists.
