Abstract in English, Afrikaans and Zulu / In an increasingly changing world, the attributes of human and physical
environments are critical in assessing human quality of life (HQoL). The research
sources consulted for this thesis point to specific relationships between urban
change, ecosystem services and the HQoL. A variety of models have been
developed in the global North to assist urban planners to manage the benefits and
stressors related to urban shrinkage, ecosystems and HQoL. In the global South
the trend is urban growth rather than shrinkage and few models are available for
this context.
Based on a mixed-method case-study approach, the Rietvlei Nature Reserve,
located in the rapidly-growing urban peripheral zone between the Tshwane and
Ekurhuleni metropolitan areas in the Gauteng province of South Africa, was
selected to assess the benefits and stressors of localised urban development,
conservation and sense of place. The purpose of the assessment was to develop
a Greenspace Stress Model of Urban Impact (GSMUI) that would be of value to
local authorities in managing the interplay of the varied functions of a nature
reserve as a greenspace in the global South. Land-use changes were analysed
using remote-sensing images. Semi-structured interviews were conducted with
purposively-selected key informants to evaluate the functions of the Reserve and
the objectives of the Ecological Management Plan for the Reserve. The benefits
and risks to the Reserve, as well as the sense-of-place aspects, were identified
through semi-structured interviews with 18 purposively-selected key informants,
181 on-site face-to-face semi-structured interviews with visitors to the Reserve,
group discussions with interest groups and electronic surveys involving 365
respondents. Data were also collected through the researcher’s own observations
and her participation in activities at the Reserve. The empirical results of the
research were verified by 14 purposively-selected key specialist informants, who
evaluated and ranked the identified benefits and stressors. Benefits and stressors
were not ranked the same from different perspectives.
Using the results of the empirical research, the researcher was able to merge and
adapt a number of models developed for the management of greenspaces in the
global North in order to develop the GSMUI specifically for the Rietvlei Reserve.
Guidelines were also developed for the application of the GSMUI in geographically
similar greenspaces in the global South. / In ‘n toenemend veranderende wêreld, is die eienskappe van menslike en fisiese
omgewings krities vir die evaluering van menslike lewenskwaliteit (HQoL). Die
navorsing wat geraadpleeg is, het spesifieke verwantskappe tussen stedelike
verandering, ekosisteemdienste en HQoL aangedui ‘n Verskeidenheid modelle is
in die globale Noorde ontwikkel om stedelike beplanners te help om die voordele
en stressors verwant aan ontwikkeling (stedelike inkrimping), ekosisteme en
menslike lewenskwaliteit, te bestuur. Onvoldoende modelle is nog ontwikkel vir die
om die teenoorgestelde neigings in die globale Suide te bestuur.
’n Gemengdemetodes-gevallestudie-benadering is gevolg om die voordele en
stressors van stedelike ontwikkeling, bewaring en sin vir plek in die Rietvlei
Natuurreservaat (geleë in die snelgroeiende stedelike randgebiedsone tussen die
Tshwane en Ekurhuleni Metropolitaanse gebiede in die Gauteng Provinsie van
Suid-Afrika) te ondersoek. Verandering in grondgebruik is deur
afstandwaarnemingsbeelde ontleed. Semi-gestruktureerde onderhoude is met
doelbewus-geselekteerde sleutelinformante gevoer om die funksies van die
Reservaat, sowel as die doelwitte van die Reservaat se ekologiese bestuursplan,
te evalueer. Semi-gestruktureerde onderhoude met 18 doelbewus-geselekteerde
sleutelinformante, 181 semi-gestruktureerde persoonlike onderhoude met
besoekers aan die Reservaat en groepbesprekings is met ereveldwagters en
belangegroepe gevoer, en 365 elektroniese vraelyste is ontleed ten einde die
voordele en risiko’s vir die Reservaat en ook die pleksin te identifiseer. Data is ook
deur middel van waarneming en deelname aan aktiwiteite in die Reservaat
ingesamel. Die empiriese resultate van die navorsing is geverifieer deur 14
doelbewus-geselekteerde sleutelinformante wat die geïdentifiseerde voordele en
stressors geëvalueer en geklassifiseer het. Voordele en stressors is verskillend
evalueer uit verskillende oogpunte.
Die gebruik van die empiriese navorsing het die navorser in staat gestel om ’n
aantal modelle aan te pas wat vir die bestuur van groenruimtes in die globale
Noorde ontwikkel is en te integreer ten einde die GSMUI te skep. Die CSMUI is
spesifiek op die bestuur van die Rietvlei Natuurreservaat gemik. Die navorsing bied
ook ‘n generiese GSMUI met implementeringsriglyne vir geografies-gelyksoortige
groenruimtes in die globale Suide. / Kumhlaba oguquka njalo, isimo sabantu nesemvelo kubalulekile ekuhloleni iqophelo
lempilo yabantu i-Human quality of life (HQoL). Ucwaningo oluhloliwe lukhombise ukuthi
kukhona ubudlelwane obuthile phakathi kokuncipha/ukwanda, inkonzo yobudlelwane
babantu nemvelo kanye ne HqoL. Lokhu kuxhumana kwehlukile kancane ezindaweni
zaseNyakatho nomhlaba (ukungcipha kwedolobha) nezindawo zaseNingizimu nomhlaba
lapho ukwanda kwamadolobha kugqame khona. Kwakhiwe amamodeli ahlukahlukile
khona eNyakatho nomhlaba ukusiza abahleli bamadolobha ukuphatha izinzuzo
nokuhluphayo okuhambisana nentuthuko (ukuncipha kwedolobha), kanye nesimo
sendawo kanye neHQol. Awekho amamodeli awenziweyo ukusiza ukuphatha isimo
esehlukile eNingizimi yomhlaba.
Ngokusebenzisa inqubo exubile, inqubo ye-case study, iRietvlei Nature Reserve
(etholakala lapho kwanda khona ngokushesha amadolobha phakathi kweTshwane neEKurhuleni kwiprovinsi laseGauteng eNingizima Afrika), yakhethwa ukuhlola izinzuzo
nezingcindezi zokuthuthuka kwamadolobha, nokugcina isimo semvelo kanye nobunjalo
obuthile bendawo. Injongo yalolu hlolo bekuwukwenza indawo ebizwa iGreenspace Stress
Model of Urban Impact (GSMUI) ezosiza iziphathimandla zendawo ukuphatha
ukuxhumana okukhona phakathi kwezinhloso ezihlukahlukene zeReserve njengendawo
eluhlaza kwiNingizimu neAfrika yomhlaba. Kwahlaziywa indlela eguqukayo
yokusetshenziswa komhlaba ngokusebenzisa imifanekiso ebheka ikude etholakala kuma
mepi akhombisa indikimba (thematic map). Kwenziwa ama-semi-structured interviews
nababambiqhaza bolwazi ababalulekile ukuhlola ukusebenza kweReserve kanye
nezinhloso zohlelo olubizwa i-Ecological Management Plan for the Reserve. Izinzuzo
nezingcindezi zale-Reserve, kanye nobunjalo obuthile bendawo, kwaphawulwa,
ngokwenza ama-semi-structured interview nabathile ababalulekile abakhethwa abayi 18
ukuxoxa nabo, futhi kwenziwa nama-semi-structured interview ngokubhekana ubuso
nobuso nezivakashi ze-Reserve ezingama 181, kanye nezingxoxo nabaqaphi abathile
besiqiwi (rangers) kanye namanye amaqembu athintekayo. Ulwazi lwaqokelelwa futhi
ngokuthi abacwaningi babheke lokho okwenzekayo kanye nokubamba iqhaza
kwimisebenzi ye-Reserve. Imiphumela yobufakazi bocwaningo yaqinisekiswa ngosolwazi
ababalulekile bobuchwepheshe abangu 14 ababekhethelwe le nhloso, abahlola babuya
babeka ngamazinga izinzuzo nezingcindezi ukwenzela ukuthi abacwaningi babuye
baphinde bakwazi ukwenza enye i-GSMUI.
Ngokusebenzisa imiphumela yobufakazi bocwaningo, umcwaningi wakwazi ukuhlela
kabusha amamodeli amaningana athile enziwe ukuphatha izindawo eziluhlaza eNyakatho
lomhlaba, ukuze enze GSMUI eqondene nokuphatha iReserve laseRietvlei. Ucwaningo
lubuye lwahlinzeka futhi i-GSMUI enabile engasetshenziswa njengemikhombandlela
yezinye izindawo eziluhlaza ezifana nalezi khona eNingizimu yomhlaba. / Geography / Ph.D. (Geography)
