Themeda Triandra Renosterveld in the Heidelberg DistrictRaitt, Gwendolyn R. 12 1900 (has links)
Thesis (MSc)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: This study investigated the composition of Themeda triandra Renosterveld in part of the
Grootvadersbosch Conservancy and the effects of selected environmental and management variables to
provide guidelines for promoting the presence of Themeda triandra in the veld.
The Zürich-Montpellier phytosociological method was used to determine the composition of the
Renosterveld communities. The point quadrat method was used to determine the cover of Themeda
triandra at three grass dominated sites and compare cover from one site with past cover measurements
at the specific site. Ordination was used to examine the effects of the environmental and management
variables on the plant communities.
Two community groups, five communities and five subcommunities were identified and described.
The Themeda triandra – Stoebe phyllostachys Grassland Community Group consists of two
communities of which one has two subcommunities. The Themeda triandra – Elytropappus
rhinocerotis Shrubland Community Group consists of three communities of which one has three
subcommunities.
The vegetation units described in this study have not been described previously in the literature. One
community belongs to Silcrete Fynbos while another subcommunity is transitional between
Renosterveld and thicket and gallery forest. The rest of the plant communities fit the definition for
Renosterveld (the local Renosterveld type is Eastern Rûens Shale Renosterveld).
Cover of Themeda triandra did not differ significantly either between sites or between years. The
comparison of Themeda triandra cover between years was done at a site that had been burnt between
the last two sampling times yet the cover was not significantly different. This indicates that fire and
other management practices did not have a negative impact on Themeda triandra at the site.
Unconstrained ordination of the dataset in which cover/abundance values were included, grouped the
relevés by moisture and disturbance but the presence/absence dataset indicates that the two community
groups have a slight transitional overlap. Constrained ordination of both datasets with a) soil variables
and b) management variables, both showed a tendency to separate the relevés into community groups,
that did not happen with topographic and vegetation variables. Ordination did not separate the
community groups into their subdivisions.
The soil variables (both nutrients and texture) influence the vegetation structure and the community
distribution.
Under the existing grazing management regime, fire at three to five year intervals promoted the
dominance of Themeda triandra by affecting the structure of the plant communities, the abundance of species other than Themeda triandra, and influencing which plant community is present. The use of
fire as a management tool was regulated by the importance of the natural veld pastures to the farmers.
The natural veld pastures are not suitable for dairy cattle in milk. Thus dairy farmers are less likely to
burn the natural veld (no planned burns only chance fires) than those who farm with mutton or beef
(planned burns on a three to five year interval). / AFRIKAANSE OPSOMMING: Die studie het die samestelling van Themeda triandra Renosterveld in ’n deel van die
Grootvadersbosch-Bewaria en die uitwerking van geselekteerde omgewings- en bestuursveranderlikes
ondersoek om riglyne vir die bevordering van Themeda triandra in die veld daar te stel.
Die Zürich-Montpellier fitososiologiese metode is gebruik om die samestelling van die
Renosterveldgemeenskappe te bepaal. Die puntkwadraat-metode is gebruik om ’n skatting van die
dekking van Themeda triandra by drie gras-gedomineerde persele te bepaal en om ’n vergelyking te
maak tussen die huidige en vorige dekking van ’n enkele perseel. Ordinasie is gebruik om die invloed
van omgewings- en bestuursveranderlikes op die plantgemeenskappe te bepaal.
Twee gemeenskapsgroepe, vyf gemeenskappe en vyf subgemeenskappe is geïdentifiseer en
gedefinieer. Die Themeda triandra – Stoebe phyllostachys Grasland-gemeenskapsgroep bestaan uit
twee gemeenskappe waarvan een in twee subgemeenskappe onderverdeel is. Die Themeda triandra –
Elytropappus rhinocerotis Struik-gemeenskapsgroep bestaan uit drie gemeenskappe waarvan een in
drie subgemeenskappe onderverdeel is.
Die plantegroei-eenhede wat in die studie beskryf is, is nie voorheen in die literatuur beskryf nie. Een
gemeenskap behoort aan Silkreet-fynbos en ’n ander subgemeenskap is ’n oorgangsfase tussen
Renosterveld en struikbosveld of woud, terwyl die res van die plantgemeenskappe binne die definisie
van Renosterveld val (die plaaslike Renosterveld tipe staan bekend as Oostelike Rûens Skalierenosterveld).
Die bedekking van Themeda triandra het nie betekenisvol gevarieer tussen óf die verskillende
lokaliteite óf die verskillende jare nie. Die vergelyking van Themeda triandra-bedekking oor tyd is
onderneem in ’n gebied wat tussen opnames gebrand is. Die bedekking het nie betekenisvol verskil
nie. Dit dui aan dat vuur en ander bestuurspraktyke nie ’n negatiewe invloed op Themeda triandra in
hierdie gebied het nie.
Onbeperkte ordinasie van die datastel met die vergelyking van bedekking/volopheidwaardes, groepeer
die relevés volgens vogtigheid en versteuring, terwyl die datastel ten opsigte van teenwoordigheid/
afwesigheid aandui dat die twee gemeenskapsgroepe ’n effense oorgangs-oorvleueling het. Beperkte
ordinasie van beide datastelle met a) grondveranderlikes en b) bestuursveranderlikes, toon albei ’n
neiging om die gemeenskapsgroepe te skei, wat nie gebeur het met die topografiese- en
plantegroeiveranderlikes nie. Ordinasie het nie die gemeenskapsgroepe onderverdeel in gemeenskappe
of subgemeenskappe nie.
Die grondveranderlikes (beide voedingstowwe en tekstuur) beïnvloed die struktuur en die verspreiding
van die plantegroei. Met die bestaande weidingsbestuur bevorder brande met ’n interval van tussen drie tot vyf jaar die
oorheersing van Themeda triandra deur die struktuur van die teenwoordige plantgemeenskap te
beïnvloed, deur die getal van die verskillende plantsoorte te beïnvloed en selfs deur die
plantgemeenskap se voorkoms te beïnvloed. Die waarde wat die boer aan die natuurlike veld as
weiveld heg bepaal die mate waartoe hulle veldbrand gebruik as ’n deel van bestuur. Die natuurlike
veld is nie geskik vir melkkoeie wat in die melkproduksiestadium is nie. Die melkboere is dus minder
geneig om die natuurlike veld te brand (geen beplande brande nie net kans brande) as die boere wat met
vleisbeeste of skape boer (beplande brande elke drie tot vyf jaar).

A case study from a gold mining company : a call for leadership towards more sustainable futuresMakuluma, Hlombe Azukile 12 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Gold mining in South Africa is an industry that is more than a century old. The impact of gold
mines on communities and the environment are enormous. This thesis is a case study based
in one of the major gold producers in South Africa that has been in operation for more than
50 years and has more than 30 years of life still left. Exploring the impact mining has had on
communities and the environment, this thesis is a call for leadership action towards
sustainable futures. This call is made through a suggested sustainable development
leadership framework. Georgius Agricola gave a warning regarding the devastating environmental impacts of
mining as early as 1556, however mining still has the same negative impacts to the
environment and people. The argument in this thesis is that, it is only through genuine
leadership that the impacts of mining can be mitigated. However leadership is looked at not
from the position of the leader or the leadership style but from the belief system of the
leader when it comes to environmental management and community development.
The motivation for the study was based in observing how leadership at our Gold mine rallied
behind prevention of mine closure when the mine was faced with electricity crisis in 2008.
The electricity crisis demonstrated that it is through genuine and committed leadership that
all challenges can be overcome including sustainable development crisis. The call for
leadership at our mine is to demonstrate the same leadership commitment in addressing
environmental and community development challenges.
The literature review begins by highlighting sustainable development global challenges and
initiatives to address them. This is followed by impacts of gold mining on society and the environment around the various regions of the world. Leadership belief systems are then
discussed, highlighting, how belief systems influence the way a leader responds to
environmental issues.
In developing the sustainable development leadership framework findings from
observations, conversations, interviews and focus group discussion that were conducted
throughout the mine are presented. The aim of the research was to determine the
understanding of employees on the impact of our company on communities, environment
and themselves and also the employees’ opinions of leadership.
The findings were that the majority of employees believe that leadership is not genuine in
addressing community, employee safety and health, and environmental issues at our
company and through interviews with leadership, the findings are that, environment and
community issues are done for compliance and reputation purposes with no genuine belief
that they should be done.
To address this understanding a call to leadership is made through a suggested sustainable
development leadership framework that takes into consideration the findings from the case
study. The thesis ends by proposing that this suggested framework should be tested further
within our company. / AFRIKAANSE OPSOMMING: Goud mynbou in Suid-Afrika is 'n bedryf wat meer as 'n eeu oud is. Die impak van goudmyne
op gemeenskappe en die omgewing is enorm. Hierdie proefskrif is 'n gevallestudie wat
gebaseer is op een van die groot goudprodusente in Suid-Afrika wat al vir meer as 50 jaar
reeds in werking is en wat 'n veredere lewensverwagting van meer as 30 jaar het. Hierdie
tesis is 'n ondersoek na die impak wat mynbou op die omliggende gemeenskappe en
omgewing het asook 'n beroep om leieskap optrede vir volhoubare ontwikkeling. Hierdie
beroep vir volhoubare ontwikkeling word gemaak deur middel van 'n volhoubare
ontwikkeling leierskap raamwerk.
Georgius Agricola het alreeds in 1556 gewaarsku teen die impak wat mynbou op die
omgewing en mense sou hê. Vandag het mynbou het egter nog steeds dieselfde negatiewe
impak op die omgewing en die mense. Die argument in hierdie tesis is dat dit slegs deur
ware leierskap is dat die impak van mynbou versag kan word. Leierskap word egter nie
bekyk uit die posisie van die leier of die leierskap-styl nie, maar eerder uit die gewetens
oortuiging oogpunt van die leier wanneer dit kom by omgewingsbestuur en ontwikkeling
van die gemeenskap.
Die motivering vir hierdie studie is gebaseer op die waarneming van hoe leierskap by ons
goudmyn mynsluiting voorkom het gedurende die 2008 elektrisiteitskrisis. Die
elektrisiteitskrisis het getoon dat uitdagings sowel as volhoubare ontwikkelings krisisse wel
deur ware en toegewyde leierskap oorkom kan word. Die versoek is nou vir ons myn om
dieselfde leierskap toewyding toe te pas waar omgewing en gemeenskap ontwikkelings
uitdagings aangepak word.
Die literatuur oorsig begin deur die globale uitdagings op volhoubare ontwikkeling onder die
vergrootglas te plaas en wys hoe om die uitdagings te addresseer. Dan volg die impak wat
die goudmynbedryf het op die omgewing en samelewing van verskeie streke in die wêreld.
Leierskap geloof oortuiging word dan bespreek met die klem op hoe geloofsoortuiging 'n
invloed het op die manier wat 'n leier reageer op omgewings kwessies. Die ontwikkeling van die volhoubare ontwikkelings raamwerk is gebasser op obserwasies,
gesprekke, onderhoude en fokusgroepsbesprekings van regoor die myn. Die doel van die
navorsing was om die begrip van die werknemers te bepaal aangaande die impak wat ons
maatskappy het op die gemeenskap, omgewing en hulself en ook om die werknemers se
opinies van leierskap te bepaal.
Die bevindinge was dat die meerderheid van die werknemers van mening is dat leierskap by
ons maatskappy nie opreg is wanneer dit kom by aanspreek van gemeenskap kwessies,
werknemer veiligheid en gesondheid, en omgewingskwessies nie. Deur middel van
onderhoude met die leiers van ons maatskappy is ook bevind dat die omgewing en die
gemeenskaps kwessies slegs aandag geniet aangesien dit vir die nakoming van vereistes en
reputasiedoeleindes verys word en nie as gevolg van 'n werklike oortuiging dat dit gedoen
moet word nie.
Om hierdie begrip aan te spreek word 'n beroep gemaak tot leierskap deur middel van
hierdie voorgestelde volhoubare ontwikkeling leierskap raamwerk wat die bevindings van
die gevallestudie in ag neem. Die tesis eindig deur voor te stel dat hierdie voorgestelde
raamwerk verder getoets moet word in ons maatskappy.

How to find the one that got away : predicting the distribution of temperate demersal fish from environmental variablesChatfield, Brenton Sean January 2008 (has links)
Knowing where species are and understanding why is paramount for developing relevant and sustainable conservation and resource management strategies. The need for this information is becoming urgent as fishing activity, resource extraction and the impacts of coastal developments continue to put marine resources under increasing pressure. As logistical and financial constraints can restrict our ability to collect data in the marine environment, the ability to predict distributions based on known associations with different environmental variables would enhance our capacity to manage these resources. Before attempting to predict the distribution of species and groups of species, the underlying species-environment relationships must be examined to determine whether associations between species and the environment can: (i) be identified, (ii) be used to develop models that can accurately predict distributions, and (iii) are general enough to allow accurate predictions beyond the sampled area. Most studies to date have compared the composition of fish assemblages between sites to determine how different environmental variables influence distribution. While widely applied, these methods do not consider how individual species respond to multiple environmental gradients and they lack the ability to predict distributions across different combinations of variables along those gradients. This lack of prediction also limits our capacity to assess what marine biodiversity is presently threatened by global, regional, and local human pressures on marine ecosystems. '...' Thus, summarising and modelling species data at higher levels would result in models with poorer predictive accuracy and a loss of ecological information. The generality of the species-environment relationships defined by the models were assessed by evaluating the transferability of models between different areas. Models developed from data collected over a wider geographic extent could more accurately predict the distribution of species across a smaller spatial extent than vice versa. This indicated that while general theories of the ecology of temperate demersal fish can be defined, the actual patterns of distribution may vary from site to site, suggesting caution when using predictions beyond the sampled area for management purposes. Overall, species distribution modelling identified how different species and groups of species responded to the combined influence of multiple environmental gradients and was able to accurately predict distributions based on the defined associations. Their application has led to a greater understanding of the species environment relationships and will help to identify those areas that may be important for conservation. Their predictive ability will allow general predictions of distribution of fish species across unsurveyed areas and provides the ability to assess the potential impact from implementing different policy and management strategies.

Challenges in modelling hydrological responses to impacts and interactions of land use and climate change.Warburton, Michele Lynn. January 2012 (has links)
To meet society’s needs for water, food, fuel and fibre the natural land cover throughout the
world has been extensively altered. These alterations have impacted on hydrological responses
and thus on available water resources, as the hydrological responses of a catchment are
dependent upon, and sensitive to, changes in the land use. Similarly, changes in the climate
through enhanced carbon dioxide (CO2) levels in the atmosphere have resulted in increased
temperature and altered precipitation patterns that alter hydrological responses. In combination,
land use change and global climate change form a complex and interactive system, whereby both
human influences and climate change manipulate land use patterns, and changes in land uses
feed back to influence the climate system, with both impacting on hydrological responses.
Relatively few studies have been undertaken examining the combined impacts of climate change
and land use change on water resources, with no consensus emerging as yet as to combined
influence of land use change and climate change on hydrological responses and the role of
geographical characteristics in determining the overriding influence. There is, however,
agreement that the effect on hydrological responses will be amplified. Given that South Africa is
currently water stressed and considered to be highly exposed to climate change impacts, an
understanding of hydrological responses to the complex interactions between land use and
climate change is crucial to allow for improved integration of land use planning in conjunction
with climate change adaptation into water resources management.
To determine the sensitivity of land use to changing climate, a sensitivity study assessing the
potential impacts of climate change on the areas climatically suitable for key plantation forestry
species was undertaken. Under sensitivity scenarios of climate change the climatically optimum
areas for specific forest species were shown to shift, with optimum areas changing in extent and
location between and within South Africa’s provinces. With potential for shifts in land use due to
climate change shown, the imperative to improve understanding of the dynamics between land
use and climate change as well as the subsequent impacts on hydrological responses was further
established.
For the assessment of climate-land use-water interactions, a process-based hydrological model,
sensitive to land use and climate, and changes thereof, viz. the daily time step ACRU model was
selected. In order to increase the confidence in results from the model in a study such as this, its
representation of reality was confirmed by comparing simulated streamflow output against
observations across a range of climatic conditions and land uses. This comparison was
undertaken in the three diverse South African catchments chosen for the study, viz. the semi-arid,
sub-tropical Luvuvhu catchment in the north of the country, which has a large proportion of
subsistence agriculture and informal residential areas, the Upper Breede catchment in the winter
rainfall regions of the south, where the primary land uses are commercial orchards and
vineyards, and the sub-humid Mgeni catchment along the eastern seaboard, where plantation
forestry is dominant in the upper reaches, commercial plantation sugarcane and urban areas in
the middle reaches, and urban areas dominate the lower reaches. Thus, in effect a space for time
study was undertaken, thereby reducing the uncertainty of the model’s ability to cope with the
projected future climate scenarios. Overall the ACRU model was able to represent the high, low
and total flows, and thus it was concluded that the model could be used with confidence to
simulate the streamflows of the three selected catchments and was able to represent the
hydrological responses from the range of climates and diversity of land uses present within the
catchments.
With the suitability of the model established for the theme of this research, the understanding of
the complex interactions between hydrological responses and land use could be improved. The
hydrological responses of the three selected catchments to land use change were varied. Results
showed that the location of specific land uses within a catchment plays an important role in the
response of the streamflow of the catchment to that land use change. Furthermore, it was shown
that the contributions of different land uses to the streamflow generated from a catchment are not
proportional to the relative area of those land uses, and the relative contribution of the land use to
the catchment streamflow varies with the annual rainfall of the catchment.
With an improved understanding of the dynamics between land uses and hydrological responses,
the impacts of climate change on hydrological responses were assessed prior to analysing the
combined impacts on land use and climate change. Five plausible climate projections from three
coupled atmosphere-ocean global climate models covering three SRES emissions scenarios
which were downscaled with the RCA3 regional climate model and adjusted using the
distribution-based scaling (DBS) approach for bias correction were used as climate input to the
ACRU model, with future projections applied to a baseline land cover scenario compared to
historical climate applied to the same baseline land cover scenario. No consistent direction of
change in the streamflow responses was evident in the Mgeni and Luvuvhu catchments.
However, decreases in streamflow responses were evident for all five scenarios for the Upper
Breede.
With an understanding of the separate impacts of land use and climate change on hydrological
responses, an analysis of the combined impacts was undertaken to determine which changes
were projected to be of greater importance in different geographical locations. Results indicated
that the drier the climate becomes, the relatively more significant the role of land use becomes,
as its impact becomes relatively greater. The impacts of combined land use and climate change
on the catchments’ streamflow responses varied across both the temporal and spatial scales, with
the nature of the land use and the magnitude of the projected climate change having significant
impacts on the streamflow responses.
From the research undertaken, the key results were
• that the climatic variable to which plantation forestry species are most sensitive is
rainfall;
• that optimum growth areas for plantation forestry are projected to shift under changing
climates, having a potentially significant impact on the landscape and thus on the
hydrological responses from the landscape;
• that the daily time-step, physical-conceptual and process-based ACRU model is
appropriate for use in land use change and climatic change impact studies as shown
through a space for time study;
• that the contributions of different land uses to the streamflow generated from a catchment
is not proportional to the relative area of that land use and that, as the mean annual
precipitation of a subcatchment decreases, so the disparities between the relative areas a
land use occupies and its contribution to catchment streamflow increases;
• that specific land use changes have a greater impact on different components of the
hydrological response of a catchment;
• that land uses which currently have significant impacts on catchment water resources will
place proportionally greater impacts on the catchment’s water resources if the climate
were to become drier; thus the drier the climate becomes, the more relatively significant
the role of land use becomes;
• that when considering any hydrological impacts of land use change, climate change or
combined land use and climate change, assessments need to consider the scale where the
localized impacts may be evident, the progression of the impacts as the streamflow
cascades through the catchment, as well as the impacts at the whole catchment scale
where the accumulation of the effects through the catchment are evident; and lastly
• that each catchment is unique with its own complexities, feed forwards and feedbacks,
thus each catchment will have a unique threshold as to where land use change or climate
change begins to have a significant influence of the hydrological response.
Given these complex interactions between land use, climate and water, there is a growing
imperative to improve the understanding of the movement of water within catchments, to be
receptive and adaptive to new concepts and information, and to developing resilient and adaptive
water management strategies for the future in a way that minimises the risks and maximises the
benefits to potential impacts of climate change. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

Barriers to the implementation of ISO 14001 (with special reference to the Durban Automotive Cluster).Turner, Andrew Iver. January 2004 (has links)
The re-emergence of South Africa into the global automotive market has had a significant impact on domestically based Original Equipment Manufactures (OEMs) and their component suppliers. While South Africa's exposure to the global market has brought about opportunities for firms to gain access to global markets, it has brought with it a vast number of pressures, including the pressure to comply with local and international environmental standards. Many of the OEM's have been set a deadline of January 2005 for ISO 14001 certification. The aim of the research was to explore and understand the complexities of the ISO 14001 implementation process with the objective of establishing the barriers that hamper its implementation, the determination of what factors influence these barriers and the investigation of possible recommendations on how organisations could overcome, or minimize, these barriers. To achieve this, a study was conducted on the Durban Automotive Cluster (DAC) investigating the following areas: 1. Determine the reasons for seeking ISO 14001 certification. 2. Determine what the organisations perceived and experienced as the barriers to implementation. 3. Determine the strategic implications of an Environmental Management System (EMS). A theoretical basis of ISO 14001, the implementation process and its strategic implications were established by reviewing previous research. A survey was conducted on the DAC's members through the use of a self-administrated questionnaire. The research showed that organisations chose to seek ISO 14001 certification in order to satisfy customer requirements and subsequently the strategic implications of ISO 14001 certification are very high. In terms of barriers to implementation, finance, resources allocation, expertise and implementation time proved to be the most problematic areas. In order for organisations to implement ISO 14001, they need to give due recognition to its strategic implications and use these implications as the basis for its justification. In order for organisations to be able to capitalize on the benefits of the system and use it to build a competitive advantage, they should attempt to integrate the environmental management system with their other management systems. / Thesis (M.B.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

Greening corporate dragon's environmental management and reporting in ShanghaiRowe, Anna Lee January 2006 (has links)
Thesis (PhD)--Macquarie University, Macquarie Graduate School of Management, 2006. / Bibliography: p. 240-276. / Introduction -- "Greening" phenomena of corporate environmental management and reporting -- China's environmental management and reporting -- Research theoretical methodology -- "Evolutionary epic" of China's environmental management institutions -- Findings and conceptualisation of CEM and CER -- Further discussion and implications -- Conclusion. / What was once the preserve of a 'green' social organisational fringe, Corporate Environmental Management (CEM) and Corporate Environmental Reporting (CER), have increasingly become a core business strategy. Research studies in this arena have been centred on industrialised nations (e.g., Guthrie and Parker, 1990), and until recently, comparatively sparse focus on developing nations (Belal, 2000), particularly in empirical studies on CER in the People's Republic of China (PRC). -- As the most populous nation on earth with one fifth of humanity (1.3 billions), China's astounding economic growth and resource consumption (Economist, 2005), provide 'telescoping' lessons in understanding the embracing of CEM and CER in rapidly developing countries. Motivated by China's unique institutional structure and embryonic stage of environmentalism (Luo and Yuwen, 2001; Chan and Welford, 2005), this field study explored the 'greening' phenomena of CEM and CER as perceived by senior managers in Shanghai. -- Utilising a modified grounded research approach (Strauss and Corbin, 1990; 1994; Whiteley, 2004), the constructivist ontology was chosen to penetrate the social context of the companies interviewed. Grounded in the data and applying interpretive epistemology, this qualitative research elucidated our awareness about the normative assumptions underpinning CEM and CER in Shanghai. The emergent model illuminated our understanding of how Chinese institutions and senior individuals within enterprises responded to the greening challenges, and how senior managers matched their personal beliefs with perceived CEM and CER. -- The results in this study indicated that CEM and CER were influenced and/or constrained by formal institutional rules (e.g., environmental policies and laws) and informal cultural institutional norms (e.g., Guanxi, trust and secrecy). The findings resonate well with institutional theoretical constraints (Powell and DiMaggio, 1991; Fogarty, 1992a) and cognitive dissonance theory (Festinger, 1962). This is attributable to the dilemma of balancing the 'yin and yang' of long term environmental sustainability and short term economic growth. / Mode of access: World Wide Web. / viii, 289 p. ill
