Connection modelling as a mechanism for addressing social inequality in Durban's peri-urban built environment : a proposed public transport hub.Cullen, Craig. 21 October 2014 (has links)
South Africa boasts such intrinsic beauty in its social and physical
geography and at the heart of this beauty lie its people. For each
culture that has fought for their beliefs and systems, wars have been
fought and lives have been lost. One thing which remains constant
however is the belief that we the people can work together to live in
peace and harmony and leave a better place to those who come after.
Apartheid South Africa was divisive in many ways and its results
have left many wounds on the country’s architectural geography.
Social inequality is manifest in the tapestry of everyday life and the
Peri-Urban scars of our past have become vivid thresholds of crosscultural
debate. The Apartheid planning model of disconnection
through race and class has seen a massive effort to refocus on
Durban’s urban core, whereas the rich tapestry of the Peri-Urban
townships is often neglected.
In order to reconnect the outer city geographies back into the urban
whole an investigation into the theory of connection between people
and their physical environment needs to be undertaken. This
dissertation looks at how the theory of connection might enable a
unified Durban and rehabilitate the tenderness of past planning
processes.
Public Transport is one such mechanism which can connect
communities, no matter the distance nor socio-economic status and it
is within this context that the dissertation offers new insight into the
critical and exciting reconnection process. / M. Arch. University of KwaZulu-Natal, Durban, 2013.

The influence of turbidity on fish distribution in Natal estuaries.Cyrus, Digby Paul. January 1984 (has links)
Studies In other parts of the world have proved that
turbidity affects aquatic life and work In Australia and
North America has shown that the distribution of some fish
species may be determined by the level of turbidity present.
This, coupled with the fact that: (i) Natal estuaries are
important as nursery areas for the juveniles of many marine
fish species, (ii) the estuaries exhibit a wide range of
turbidities and (iii) little was known of the effects of
turbidity on the fish populations in estuaries, led to this
study being undertaken.
Turbidity and its effects on fish distribution In
Natal estuaries was investigated from January 1980 to June
1983. Lake St. Lucia, which is predominantly turbid but also
has clear water areas, was the main study area. Six other
estuarine systems sampled were chosen to cover a wide range
of estuarine types and turbidities. Field sampling was
undertaken to determine which species were present under
different turbidities, simultaneously physical factors which
were potentially affecting fish distribution were also
monitored. In addition to this, laboratory equipment which
enabled a turbidity gradient to be established In a choice
chamber tank was used to test the turbidity preferences of 10
common estuarine species for which field data were available.
These tests allowed the elimination of all physical factors
except turbidity.
Of the physical parameters monitored In the field,
turbidity, temperature and food availability In the benthos,
were determined as being important In affecting fish
distribution within estauries. However, comparison of fish
distribution data for twenty species, with these factors
showed that turbidity was exerting the major influence. It
was also found that fish species occurred In one of five
groups, inhabiting either clear, 'clear to partially turbid',
intermediate or turbid waters or they were indifferrent to
turbidity. Laboratory results for eight of ten species tested
showed significant aoreement with the field data. The results of this study have shown that turbidity is
the most important factor determining the distribution of
juvenile marine fish In estuaries and that the greatest
number of species are present in , waters which are not clear.
The attraction to and presence in such systems appears to be
related to the fact that turbid estuaries 'provide protection
from fish and bird predators while also acting to reduce
intraspecific predation. Of factors attracting juvenile fish
into estuaries, turbidity is probably the single most
important acting in this respect. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 1984.

The impact of migration on rural development : a case study of EMabhuqwini in Nkandla.Shezi, Xolani. 23 September 2014 (has links)
This dissertation concentrates on the subject of migration from the less researched angle of
the rural areas losing migrants. This dissertation is premised upon the hypothesis that
emigration of skilled people stifles development in rural areas and this in turn leads to the
lack of development. The lack of development causes emigration. I am arguing that this
vicious cycle must be broken down through leadership committed to achieving
development goals and through personal sacrifices of skilled people remaining in rural
areas.
Therefore, this dissertation seeks to establish the impact that migration has on rural
development. It looks at the case of eMabhuqwini as the study’s focal point. There are two
arguments that are advanced by the thesis:
(1) Migration negatively impacts on development in the area of eMabhuqwini. The
more able‐bodied, skilled and capable people emigrate, the higher the likelihood that the
area they leave will stay underdeveloped. This is because people who have the capacity to
drive development in the area will have left. At the same time, if the area is
underdeveloped, people are likely to leave it and seek greener pastures – especially in terms
of better living conditions and employment opportunities – elsewhere, particularly in more
developed urban areas.
(2) Political infighting between political parties appears to be the main cause of the slow
(if any) pace of service delivery and development in the area. This is so because of growing
political intolerance among political parties in South Africa. This political intolerance is also
characterised by an unwillingness to accept political defeat. As such, this process has
dictated the terms of and speed of service delivery as there is little will on the part of
political leaders to spearhead development in an area governed by the opposition.
I further provide a comprehensive conceptual framework on migration theory, a detailed
presentation of the case study area, a three‐pronged empirical study consisting of
interviews with thirty‐two households, household in‐depth survey (6 respondents) as well as
three focus groups.
Quantitatively, 32 respondents answered a semi‐structured research questionnaire. Six of
the same people were also requested to respond to an open‐ended research schedule that
sought to gain answers to open‐ended questions. The questions themselves were divided
into two sections, a closed‐ended part as well as an open‐ended part. Quantitative
questionnaires were analysed using the SPSS computer program, while the others were
analysed thematically. In terms of conclusions and recommendations, it was observed that the two arguments
were confirmed: that migration does have a negative impact on development; and that, to
minimise this impact, or to reverse the process, an intensive effort must be put into
encouraging the government, together with traditional and local leadership, to deliver
services to the people so as to develop the area and minimise the impact of migration. / Thesis (M.T.R.P.)-University of KwaZulu-Natal, Durban, 2013.

Community structure and function of macrobenthos in three feature areas of the Natal Bight, South Africa.Untiedt, Candice Bobby. January 2013 (has links)
The Natal Bight off the east coast of South Africa is a unique shelf habitat, exhibiting high secondary productivity and supporting high diversity. Ecosystem attributes are influenced by local oceanographic features and outwelling via one of the largest rivers in the country. This study forms part of a larger, multi-institutional, multi-disciplinary study under the second phase of the African Coelacanth Ecosystem Programme (ACEP II) Natal Bight Project, investigating how material sources, posited to be derived from these features, shape the ecological structure and functioning of the region. Macrobenthic samples were collected along cross shelf transects off Richard’s Bay, Durban and the Thukela River mouth during two cruises, corresponding with periods of variable rainfall. Macrobenthic communities were classified taxonomically, to the lowest level possible, and functionally. Community patterns were investigated within and between feature areas and related to measurable environmental factors in order to determine environmental drivers and assess the importance of identified oceanographic features. Environmental parameters measured included sedimentary characteristics as well as physico-chemical conditions in the surrounding pelagic milieu. A total of 38 215 individuals belonging to 826 taxa were recorded from the three feature areas, of which the majority were Polychaeta and Crustacea. An in-depth investigation of the polychaete component has shown that this group can be used as a proxy for the whole macrobenthic community which has important implications for future studies. Facultative feeding modes dominated the trophic functioning macrobenthic communities sampled on the Natal Bight. Primary community metrics of abundance and numbers of macrobenthic taxa were reduced from the high to low rainfall period but differences were not significant, probably due to the lack of temporal repetition. The Thukela feature area was found to support the most abundant and taxon rich macrobenthic community. Mid-shelf stations sampled along the Thukela and Durban transects were in close proximity to the coarse paleo-dune cordon, running along the 60 m isobath and supported a diverse assemblage. Despite the lack of temporal repetition in the present study, there were significant short-term changes in the structure and functioning of macrobenthic communities on the Thukela shelf. This suggests that Thukela River outflow has a significant effect on the functioning of the Natal Bight ecosystem. This was surprising given the importance which has previously been placed on the Cape St. Lucia upwelling cell in terms of contributing nutrients and sustaining biological productivity and diversity on the Natal Bight. / Thesis (M.Sc.)-University of KwaZulu-Natal, Durban, 2013.

The usage pattern of nutritional supplements amongst University of KwaZulu-Natal master of business administration (MBA) students.Bright, Lizell. January 2012 (has links)
Nutritional supplements are a combination of complementary medicines and functional foods. While research suggests that the usage of nutritional supplements is increasing worldwide, the growth of the industry is being hampered by a lack of understanding on the part of consumers. The main aim of this study was to determine the usage pattern of nutritional supplements amongst University of KwaZulu-Natal (UKZN), Masters of Business Administration (MBA) students registered in 2011. Research data for this study was obtained by surveying UKZN MBA students. From a population of 250, a probability sample of 152 responses was statistically analysed for the research. Quantitative data obtained from a questionnaire was used and analysed to meet the study’s objectives. A salient finding of the study was that there is an “uptapped” market amongst Black consumers that the nutritional supplement businesses should target. The study revealed that the majority of the respondents did not fully understand the benefits of nutritional supplements.
The overall results of the study revealed the usage patterns of nutritional supplements amongst UKZN MBA students. The results also identified which population group and which gender consumed nutritional supplements. This study could assist nutritional supplement businesses to gain market share. The results can be used to formulate marketing strategies and to provide businesses with a competitive advantage. The recommendations of the study were that growth in the nutritional supplement industry could be achieved by targeting the Black market and that additional marketing campaigns were needed to educate and inform consumers about the benefits of nutritional supplements. / Thesis (MBA)-University of KwaZulu-Natal, Durban, 2012

Effectiveness of tuberculosis management at KwaMsane clinic.Okesola, Nonhlanhla E. January 2011 (has links)
South Africa has the highest Tuberculosis (TB) incidence in the world. In 2006 it was
estimated that in South Africa, with only 0.7% of the world population; some 28% of HIV
positive adults had TB. To treat one patient with ordinary TB costs the Health Department
approximately R310 and a patient with multi-drug TB (MDR-TB) more than R2000. TB
has added to the burden of a country which is struggling to cope with the HIV/AIDS
pandemic. TB is one of the national health priorities of the Department of Health (DoH).
KwaMsane Clinic is located at Mtubatuba, in the UMkhanyakude district. The
uMkhanyakude district has the highest prevalence of HIV and the highest number of cases
of TB in South Africa. The UMkhanyakude district stretches from the Umfolozi River,
which is south of Mtubatuba, to the Mozambique and Swaziland borders. The clinic is a
Primary Health Care centre and is open 24 hours a day. UMkhanyakude has a population
estimated at 614,046. According to the DoH National Tuberculosis Management
Guidelines (2009), the greatest challenge that the TB programme faces are inadequate
financial and human resources for TB control, resulting in poor case detection, increasing
numbers of multi-drug resistance TB, extensively dry-resistance TB and poor quality data
collection and data analysis.
The study set out to identify the challenges that KwaMsane clinic faces in terms of TB
management. It was found that the problem facing KwaMsane clinic’s effectiveness was
largely due to two factors. The first is the delay in patient diagnosis and the second is the
negative nurse/patient ratio which affects the workload and compromises levels of service
delivery. The population was sufficiently small, but statistically adequate and all 31
employees were surveyed. Of these, 61% or 19 of the employees agreed that there is a
delay in patient diagnosis. The recommendations for KwaMsane clinic include more
effective recruiting of staff; attracting and retaining qualified and experienced health
personnel; equipment and resources need to be more available; and the clinic management
should ensure that they have enough personnel to cope with high number of patients More
research is needed on issues such as recruiting attracting and retaining qualified and
experienced health personnel; provision of skills training for clinic management and other
health personnel to improve service delivery; management of information systems at
primary health care clinics for record keeping and data analysis; and integrating TB and
HIV/AIDS management. / Thesis (MBA)-University of KwaZulu-Natal, Durban, 2011.

Language and literacy practices of African immigrants in Pietermaritzburg.Cheelo, Mutinta. 20 May 2014 (has links)
Language and literacy are of central importance to communication for most people in the
world today. This case study investigates the language and literacy practices amongst African
immigrant families in Pietermaritzburg. There are many immigrant families from different
countries with different home languages and different backgrounds. This study examines the
languages used in these different immigrant homes, and what factors lead to the choice of the
languages. It investigates what literacy practices these families are engaged in. The study
further examines the effects that the choice of languages used in these homes and the literacy
practices engaged in have on the education of both the parents and their children. The
literature reviewed for this study focused on six major themes on literacy, namely; (i) literacy
as social practice, (ii) literacy networks, (iii) literacy domains, (iv) literacy events, (v)
language, literacy acquisition and social identity and (vi) second language socialization.
To collect the data necessary to for the study, three methods were used: group interviews,
home observation and participant observation. Data was examined using Street’s ideological
model of new literacy studies as theoretical framework.
The findings for this study show that there are different languages used in each home but that
the use of English is common in all the homes. The findings show that the literacy practices
that these families are engaged in are similar despite coming from different countries.
The study found that texts using cell phones play a major role during communication. This
shows that electronic technology plays a vital role in both the children’s and adults’ language
and literacy development. / Thesis (M.Ed.)-University of KwaZulu-Natal, Pietermaritzburg, 2014.

Understanding high school teachers' perceptions of the factors influencing academic success of learners in rural KwaZulu-Natal.Edwards, Michelle. January 2013 (has links)
The value of schools as systems for encouraging positive adaptation and development has
gained recognition in resilience research. As key role players in the school environment,
teachers play a central role in fostering resilience among learners. Further, the context of the
school environment provides understanding into the many systems in which learners are
situated which encourage or hinder the development of resilience strategies. Learners in
South Africa face many barriers in attempting to access education. These challenges are
especially prevalent in rural areas, where poverty, unemployment and poor health add an
extra burden on learners and teachers. Despite this, there are learners who are able to achieve
academic success. They are in essence resilient. This study aimed to understand the
perceptions of teachers of the factors which influence learner success in South Africa from a
strengths perspective. A qualitative approach and purposive sampling were employed to
conduct two focus groups with teachers from two rural high schools in KwaZulu-Natal. The
Participlan method was used to conduct the focus groups as it allowed the groups’ control
over organising main themes and ideas. Data was analysed using thematic analysis and
concepts from resilience theory and the Bio-ecological Systems Theory were used to organise
and understand the findings. The results indicated that the teachers have a contextual view of
the factors influencing learner success and they underemphasise the role of the individual.
The key role of the teacher and the school as a site for fostering resilience was also evident.
Suggestions for further research include exploring the effectiveness of reactive strategies
developed by the participants and encouraging the development of characteristics found in
resilient schools. / Thesis (M.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Perceptions of the conservancy concept, common pool resources and the challenge of collective action across private property boundaries : a case study of the Dargle Conservancy, South Africa.Mwango, Nelly Chunda. January 2013 (has links)
Conservancies are viewed as playing an important role in enabling the landscape-scale
management of biodiversity and ecosystem services by extending conservation areas beyond the
boundaries of formally protected areas (PAs). In the South African context of the Biodiversity
Stewardship Programme (BSP), conservancies are viewed as a viable landscape-scale approach
to stewardship that can contribute to meeting government conservation mandates of conserving
biodiversity and expanding its protected area network outside state PAs, through partnerships
with private landowners. Using the landscape approach theory, I determined that the landscapescale
context of biodiversity and ecosystem services creates common pool resources (CPRs) that
require collective action in the form of integrated management planning across private property
boundaries. In this context, conservancies create multi-tenure conservation areas with landscape
meanings and associated benefits that require landscape-scale collective action. However, using
property and collective action theories, I deduced that when landowners in a conservancy seek to
engage collective action for landscape-scale conservation objectives under the BSP, they are
challenged by the tension between individual meanings defined at the scale of their own property
and landscape-scale meanings that straddle property boundaries. This tension is reinforced by
property rights in which each actor holds resources under a private property rights regime while
the landscape-scale meanings of CPRs need to be addressed in a common property rights regime
context. Based on this complexity, my research set out to determine peoples’ meanings attached
to the concept of conservancy and to illustrate how these meanings influence the ability to attain
collective action necessitated by the CPR management regimes superimposed on private
property rights regimes. This was with the view to refine the concept of conservancy to enable
those who establish and engage with conservancies to better appreciate the implications and the
nature of the governance regime that is required for success.
My results show that the success of a conservancy as a landscape approach is dependent on
landowner commitment to collective action. Landowner commitment is also influenced by a
shared understanding of the conservancy as a multi-tenure conservation area managed collectively for the conservation of biodiversity and ecosystem services across private properties.
Thus Conservancy members need to develop an understanding of the conservancy as an area of
contiguous multiple private properties that require collective management through integrated
management planning, guided by a Dargle Conservancy management plan. Conservancy
members also need to develop an understanding of the contiguous properties as encompassing
biodiversity and ecosystem services that require common property rights regimes for their
sustainable use and management. This explicit landscape approach will encourage landowner
commitment to the conservation objectives set out in the multi-tenure conservation areas.
I use my research findings to identify three issues for further research in community-based
conservation areas as a landscape approach to conservation: firstly, research that focuses on
developing integrated management plans for landscape-scale bio- and eco-regions by designating
contiguous private properties into different categories of PAs according to collectively agreed
conservation objectives; secondly, research that focuses on developing appropriate management
regimes based on a model of multi-tenure conservation areas managed collectively for the
conservation of biodiversity across private properties; and thirdly, research that focuses on
establishing social structures for the development of adequate capacity and decision-making at
the conservancy level to implement a landscape approach that supports ecological functions
beyond individual boundaries. Building on this research will provide an important continuous
learning process between conservancies and conservation agencies. Such learning is necessitated
by the complexity of continually changing social and ecological systems that influence
perceptions and behaviours. / Thesis (Ph.D)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Patch grazing in the humid grasslands of KwaZulu-Natal.Lütge, Bernd Uwe. January 1995 (has links)
Patch grazing may be an important factor providing the focus from which wide-scale veld
degradation has occurred in the humid grasslands of KwaZulu-Natal. A number of discrete
studies were therefore initiated to examine the patch grazing patterns and selected factors
which may influence patch grazing at two sites in the humid grasslands of KwaZulu-Natal.
The sites were located at Ukulinga Research Farm, situated in the Southern Tall Grassveld,
and Kokstad Research Station in the Highland Sourveld.
An investigation into the frequency and intensity of gazing patches and non-patches at
Ukulinga Research Farm indicated that patch grazing was most evident and most extensive
during summer and autumn. As forage in the patches became limiting during winter animals
were forced to forage in areas not frequently grazed during the season. The patch grazing
pattern was further modified by the time of grazing commencement after a burn in early
spring. Early grazing significantly reduced the extent of patch grazing. With early stocking
animals were forced to graze less selectively while with increased delay in the
commencement of grazing, animals became increasingly patch-selective. Early grazing in
conjunction with an autumn rest and heavy grazing during winter could significantly reduce
patch grazing.
Urine and dung significantly influenced the patch grazing pattern. The sward surrounding
a urine deposit was preferentially grazed by both cattle and sheep for a period of at least six
months after deposition. Cattle rejected the sward surrounding cattle and sheep dung
immediately after deposition and for a period of up to six months. Sheep also rejected cattle
and sheep dung patches immediately after deposition. As dung deposits aged, sheep tended
to increase their grazing around both cattle and sheep dung pats, and after six months dung
did not seem to influence sheep grazing. Urine may be an important factor influencing patch
initiation and consequent patch development.
A study to examine the characteristics of patches and non-patches in the Highland Sourveld
revealed that patches were characterised by lower soil moisture, soil depth and hydraulic
conductivity, but by a higher soil nutrient status. Patches and non-patches could also be distinguished in terms of species composition and basal cover. Patches were characterised
by Increaser II species, especially Microchloa caffra and, non-patches by Increaser I species
such as Trachypogon spicatus, Alioteropsis semialata and Eulalia villosa.
Three seasons of patch grazing at Kokstad Research Station negatively influenced the vigour
of Themeda triandra in patches relative to the non-patches. The vigour of T. triandra in
patches was consistently low throughout a full season's rest. The vigour of T. triandra in
non-patches was initially significantly higher than the vigour in the patches and remained so
for c. 24 weeks. Vigour measurements at the start of the following season showed that
photosynthate accumulation had taken place and a full seasons rest proved to be sufficient in
restoring the vigour of T. triandra in patches to the same level as that in non-patches. A full
seasons rest did, however, not prevent animals from regrazing the same previously grazed
patches the following season. Growth in patches also started c. six weeks later than in nonpatches
and above-ground herbage production in patches was significantly lower than nonpatches
for at least 20 weeks after a bum. At the end of a full season's rest above-ground
herbage production in patches was still slightly lower than that in non-patches possibly due
to a difference in species composition between patches and non-patches.
Some implications of patch grazing are discussed together with an evaluation of some
management recommendations for the humid grasslands with the aim of reducing the
potential for patch degradation. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 1995.
