Thesis (MA (Geography and Environmental Studies))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Tourism development is a complex process which many researchers have attempted to understand from various social science perspectives. This study adopts a geography approach to analyse tourism development in the Inhambane Coastal Zone (ICZ) by using the Miossec (1976) and the Butler (1980) models as basic frameworks for analyses. Although both models were found to be useful, they require more accurate data than what was generally available for the ICZ. Before the country’s independence in 1975, Mozambique was considered one of many premier tourism destinations in Southern Africa and the tourism sector had played an important role in the economy of the country. The 16 years period of internal conflict (1976- 1992) resulted in a rapid decline in the performance of the sector. Since the end of the armed conflict in 1992 and the democratic transition, a slow recovery of the tourism sector in Mozambique has set in. Tourism facilities for accommodation and leisure activities have increased considerably over the last ten years, despite the absence of any integrated tourism planning. In this study questionnaire surveys of tourist establishment representatives and local residents as well as focus group discussions and interviews were conducted to acquire primary data to analyse the evolution of the ICZ as a tourist destination during the period 1992 to 2008. In addition, secondary sources such as reports, tourism plans, tourism statistics and maps of the study area were used. It was found that tourism is developing slowly in the ICZ and the opening up (or rediscovering) of the zone as a destination remains limited due to the slow development of infrastructure in general. The tourism nodes are in different stages of their destination life cycle and the local residents living in the seven communities react differently toward tourism development. The ICZ has not progressed further than phase two in Miossec’s model. The Miossec model was found a suitable tool for analysing tourism development in the ICZ but it remains a challenge to identify both the evolutionary stage of the ICZ as a destination and the stage of each tourism node. The study also found that local residents in the ICZ expressed positive views about tourism development but they are still not satisfied with the current benefits they acquire from the current development status of tourism in the zone. / AFRIKAANS SUMMARY: Baie navorsers het reeds gepoog om die komplekse proses van toerisme-ontwikkeling vanuit verskeie sosiaal-wetenskaplike benaderings te verstaan. Hierdie studie volg ʼn geografiese benadering ten einde toerisme-ontwikkeling in die Inhambane Kussone (ICZ) met behulp van die Miossec (1976) en Butler (1980) modelle as basiese raamwerke te analiseer. Alhoewel beide modelle as bruikbaar bevind is, benodig hierdie modelle meer akkurate data as wat algemeen vir die ICZ beskikbaar is. Voor die land se onafhanklikheid in 1975, was Mosambiek gereken as een van vele vername toerisme bestemmings in Suidelike Afrika en die toerisme sektor het ʼn belangrike rol in die ekonomie van die land gespeel. Die 16 jare lange interne konflik (1976-1992) het tot ʼn snelle agteruitgang van die sektor se prestasie gelei. Sedert die einde van die gewapende konflik in 1992 en die oorgang na ʼn demokrasie, het die toerisme sektor in Mosambiek ʼn stadige herstel beleef. Toerisme fasiliteite vir akkommodasie en ontspanningsaktiwiteite het, ten spyte van die afwesigheid van geïntegreerde toerisme beplanning, aansienlik toegeneem. In hierdie studie is daar deur middel van ‘n vraelysopname aan verteenwoordigers van toerisme verwante besighede en plaaslike inwoners, asook fokus-groep besprekings primêre data in gesamel ten einde die evolusie van die ICZ as toeriste bestemming gedurende die tydperk vanaf 1992 tot 2008 te analiseer. Daarbenewens is sekondêre bronne soos verslae, toerisme planne, toerisme statistieke en kaarte van die studiegebied gebruik Daar is bevind dat toerisme in die ICZ stadig ontwikel en dat die herontdekking van die sone as bestemming beperk bly as gevolg van die stadige ontwikkeling van die infrastruktuur in die algemeen. Die toerisme nodusse is in verskillende stadia van hulle individuele bestemmingsiklusse, en die plaaslike inwoners in die sewe gemeenskappe reageer verskillend teenoor toerisme ontwikkeling. Die ICZ het nie verder as fase twee van die Miossec model gevorder het nie. Daar is ook vasgestel dat die Miosec model ʼn gepaste instrument is vir die analise van toerisme ontwikkeling in die ICZ, maar dit bly ʼn uitdaging om die evolusionêre stadium van die ICZ as ‘n bestemming in geheel asook die stadium van elke toerisme-nodus te kan identifiseer. Die studie het ook bevind dat plaaslike inwoners van die ICZ positiewe menings oor toerisme ontwikkeling het, maar nog steeds nie tevrede is met die huidige voordele wat hulle uit die huidige ontwikkelingstatus van toerisme in die sone ontvang nie.

Thesis (MSc (Geography and Environmental Studies))--University of Stellenbosch, 2005. / Land degradation in Lesotho is undermining the finite resource on which people depend for survival. Use of satellite imagery has been recommended for monitoring land degradation because remotely sensed data enable monitoring of large areas at more frequent intervals than intensive ground based research. Various techniques have been developed for land cover change detection. In the present study, vegetation changes were identified by image differencing, which involved finding the difference between the earlier date NDVI image and the later date image. NDVI images are among products that are generated from the NOAA AVHRR sensor to provide information about the quantity of biomass on the earth’s surface. The resulting NDVI change data showed land areas that had experienced vegetation loss, which were identified as potentially degraded. The change data were combined with other data sets to determine how potentially degraded areas were influenced by different environmental variables and population pressure. These data sets included land cover, ecological zones, elevation, soil and human and livestock populations. By integrating NDVI data with ancillary data, land degradation was attributed to both demographic pressure and biophysical factors. Widespread degradation was detected on the arable parts of the Lowlands where cultivation was intensive and human settlements were extensive. Signs of grassland depletion and forest decline were also evident and were attributed to population expansion, overgrazing and indiscriminate cutting of trees and shrubs for firewood. Extensive biomass decline was also associated more with soils in the lowlands derived from sedimentary rocks than soils of basalt origin that occur mostly in the highlands. Significant degradation was evident on gentle slopes where land uses such as cultivation and expansion of settlements were identified as the main causes of the degradation. There was evidence of greater vegetation depletion on north and east-facing slopes than on other slopes. The depletion was attributed to the fragility of ecosystems resulting from intense solar radiation. The study demonstrated that NOAA AVHRR NDVI images could be used effectively for detecting land cover changes in Lesotho. However, future research could focus on obtaining and using high resolution data for detailed analysis of factors driving land degradation.

Thesis (MA (Geography and Environmental Studies))--University of Stellenbosch, 2005. / Salinisation is a major environmental hazard that reduces agricultural yields and degrades arable land. Two main categories of salinisation are: primary and secondary soil salinisation. While primary soil salinisation is caused by natural processes, secondary soil salinisation is caused by human factors. Incorrect irrigation practices are the major contributor to secondary soil salinisation. Because of low costs and less time that is associated with the use of remote sensing techniques, remote sensing data is used in this study to identify and map salinised irrigated land between Upington and Keimoes, Northern Cape Province, in South Africa. The aim of this study is to evaluate the potential of digital aerial imagery in identifying salinised cultivated land. Two methods were used to realize this aim. The first method involved visually identifying salinised areas on NIR, and NDVI images and then digitizing them onscreen. In the second method, digital RGB mosaicked, stacked, and NDVI images were subjected to unsupervised image classification to identify salinised land. Soil samples randomly selected and analyzed for salinity were used to validate the results obtained from the analysis of aerial photographs. Both techniques had difficulties in identifying salinised land because of their inability to differentiate salt induced stress from other forms of stress. Visual image analysis was relatively successful in identifying salinised land than unsupervised image classification. Visual image analysis correctly identified about 55% of salinised land while only about 25% was identified by unsupervised classification. The two techniques predict that an average of about 10% of irrigated land is affected by salinisation in the study area. This study found that although visual analysis was time consuming and cannot differentiate salt induced stress from other forms; it is fairly possible to identify areas of crop stress using digital aerial imagery. Unsupervised classification was not successful in identifying areas of crop stress.

Thesis (MSc (Geography and Environmental Studies))--University of Stellenbosch, 2005. / Since mechanised borehole drilling began in South Africa in the late 1800s, over 1 100 000 boreholes have been drilled. As the country’s growing population and the perceived impacts of climate change increase pressure on water surface supplies, attention is turning to groundwater to meet the shortfall in water supply. This will mean even more drilling will take place. Until the introduction of the Standard Descriptors for Boreholes, published in 2003, South Africa has not had a set of guidelines for borehole information capture. This document provides a detailed description of the basic information requirements needed to describe and characterise the process of drilling, constructing, developing, managing and monitoring a borehole. However, this document stands alone as a specification with little or no implementation or interpretation to date. Following the development and publishing of the ArcHydro data model for water resource management by the CRWR based at the University of Texas at Austin, there has been a great deal of interest in object-oriented data modelling for natural resource data management. This thesis describes the utilisation of an object oriented data modelling approach using UML CASE tools to design a data model for South African Boreholes, based on the Standard Descriptors for Boreholes. The data model was converted to a geodatabase schema and implemented in ArcGIS.

Thesis (MA (Geography and Environmental Studies))--University of Stellenbosch, 2009. / This study combines qualitative and quantitative techniques in an inquiry into the influence of rural tourism on the development and structure of Sutherland from 2001 till 2005. Sutherland, like most small rural towns in the Central and Western Karoo, is/was in the process of decline. Rural tourism is seen as a solution to curb the process of decline. The study investigates this assumption by analyzing the positive and negative impacts of tourism on the economic, social and environmental spheres of Sutherland and looks at concomitant structural changes. Special emphasis is placed on the changing nature of Sutherland’s reason for existence and the dualistic processes of degradation on the one side and tourism development on the other. These complex time-spatial and site-specific trends are analyzed and recommendations are made for the management of the tourism industry of Sutherland.

Thesis (MA (Geography and Environmental Studies))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The research problem addressed in this study is how to ascertain the primary determinants of house prices in Hout Bay. This overarching aim encompasses three interwoven aspects. The research attempts first to determine which factors generally affect property prices in Hout Bay; second, to assess the extent to which individual factors affect house prices; and third, to discover the role variables collectively play in determining house prices in Hout Bay. Four objectives emerge from this subdivision of the aim, namely identify potential house priceinfluencing factors in Hout Bay; quantify the selected locational variables; statistically analyse the variables to distinguish the significant and insignificant ones; and use regression analysis to deduce the collective and individual influences of the significant factors on house prices. Structured interviews were conducted with representatives of 12 estate agencies in Hout Bay to uncover factors affecting the local property market. Through insights gleaned from the literature, manipulation of municipal valuation and cadastral data and the structured interviews, 39 structural and site-related variables, 18 distance variables and 11 socioeconomic variables were constructed. Several preliminary and descriptive analyses performed on the variables gave a general impression of the distribution of data and assisted in identifying statistically significant variables for determining house prices. These analyses included measures of central tendency (mean, median and mode); measures of dispersion (minimum and maximum values, range, standard deviation, skewness and kurtosis); the compilation of histograms for each variable; analysis of variance (ANOVA) on nominal data variables; and the creation of 2D scatterplots for ordinal data variables. Spearman rank order correlation was performed on the nominal and ordinal data variables. Statistically weak variables and those exhibiting signs of multicollinearity were eliminated. A best-subsets regression analysis was executed on the remaining variables. The regression model performed adequately, explaining close to 54% of the variation in house prices in Hout Bay. Among the individual factors, the size of the erf was the strongest predictor of the house price dependent variable, house size was the second most important factor, while distance to busy roads and quality of the house shared similar importance. Regression residuals were also mapped to expose spatial patterns. It is recommended that comparable research be conducted on a citywide scale, that variables be quantified differently and that new GIS techniques be incorporated in future studies. / AFRIKAANSE OPSOMMING: Die navorsingsprobleem wat hierdie studie aanspreek, is hoe om vas te stel wat die primêre faktore is wat huispryse in Houtbaai bepaal. Hierdie oorkoepelende doelwit vervat drie onderling verwante aspekte. Eerstens, poog die navorsing om te bepaal watter faktore in die algemeen huispryse in Houtbaai beïnvloed; tweedens, om te assesseer tot watter mate individuele faktore huispryse affekteer; en derdens, om te ontdek watter kollektiewe rol veranderlikes in die bepaling van huispryse in Houtbaai speel. Vanuit hierdie onderverdeling van die navorsingsdoelwit het vier doelstellings ontstaan, naamlik identifiseer die potensiële faktore wat huispryse in Houtbaai beïnvloed; kwantifiseer die geselekteerde liggingsveranderlikes; voer verskeie analises uit op die veranderlikes om die beduidende en onbeduidende veranderlikes te identifiseer; en benut regressie-analise om die kollektiewe en individuele invloed van beduidende faktore op huispryse in die studiegebied vas te stel. Gestruktureerde onderhoude is met verkoopslui van 12 eiendomsagentskappe in Houtbaai gevoer om die faktore te bepaal wat die plaaslike eiendomsmark beïnvloed. Deur middel van insigte verkry uit die akademiese literatuur, manipulasie van munisipale waardasie- en kadastrale data en die gestruktureerde onderhoude is 39 strukturele en liggingsverwante veranderlikes, 18 afstandsveranderlikes en 11 sosio-ekonomiese veranderlikes geskep. Verskeie analises wat op die veranderlikes uitgevoer is, het ‘n algemene indruk van die verspreiding van die data verskaf en het die identifisering van statistiesbeduidende veranderlikes bevorder. Hierdie analises het maatstawwe vir sentrale neiging (rekenkundige gemiddelde, mediaan en modus); maatstawwe vir dispersie (minimum en maksimum, variasiewydte, standaardafwyking, skeefheid en kurtose); die samestelling van histogramme vir elke veranderlike; die analise van variansie (ANOVA) op veranderlikes met nominale data; en die skep van 2D-spreidingstippe vir veranderlikes met ordinale data behels. Spearman se rangorde korrelasie is op beide die nominale en ordinale data uitgevoer. Statistiesonbeduidende veranderlikes, of dié wat tekens van multikollineariteit met ander veranderlikes getoon het, is geëlimineer. ‘n Beste deelversameling regressie-analise is uitgevoer op die oorblywende veranderlikes. Die regressiemodel het gepaste resultate behaal deurdat dit byna 54% van die variasie in Houtbaai se huispryse verklaar het. Van die individuele veranderlikes was die grootte van die erf die sterkste voorspeller van die huisprys afhanklike veranderlike, huisgrootte was die tweede belangrikste faktor, terwyl afstand van besige paaie en die kwaliteit van die huis soortgelyke invloed gedeel het. Die regressiemodel se residu’s is gekarteer om ruimtelike patrone vas te stel. Dit word aanbeveel dat soortgelyke navorsing op ‘n stadswye skaal uitgevoer word, dat die veranderlikes op ander wyses gekwantifiseer word en dat nuwe GIStegnieke in toekomstige studies aangewend word.

Thesis (MSc)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: Multi-criteria decision-making (MCDM) is a set of techniques designed specifically for the analysis of complex problems. Geographical Information Systems (GIS) focus on spatial problem-solving and spatial analysis. The integration of these methodologies offers a powerful approach to decision making. Despite the fact that most spatial decision problems are multi-criteria problems by nature, the process of MCDM is not well established or effectively integrated into the field of spatial analysis and GIS. This research focuses on bridging the gap between MCDM and GIS. To this end, a generic MCDM extension was designed and implemented in ArcView. As a result, a first version MCDM extension is offered. The extension expands ArcView's functionality with a limited set of MCDM methods. This functionality is illustrated on two problems involved with developing the tourism potential at Coutada 16 Wildlife Reserve in Mozambique. The MCDM extension facilitates procedures that allow the evaluation of spatial problems and includes the ability to deal with both raster and vector data. This system offers a generic problemsolving environment, which can be used to evaluate geographical problems of any nature. This research identifies a number of improvements to the developed functionality and successfully illustrates the potential problem-solving capabilities associated with MCDM integrated with ArcView. / AFRIKAANSE OPSOMMING: Multi Kriteria Besluitneming (MKBN) is n versameling metodes vir die analise van komplekse probleme. Geografiese Inligtingstelsels (GIS) fokus op geografiese probleemoplossing en analise. Die integrasie van hierdie twee metodologieë bied 'n kragtige benadering tot besluitneming. Ten spyte daarvan dat die meeste geografiese probleme in wese meerveranderlik van aard is, is MKBN nie effektiefbinne die raamwerk van GIS geïntegreer nie. Hierdie studie fokus op die oorbrugging van die gaping tussen MKBN en GIS. Met hierdie doel voor oë is 'n generiese MKBN-uitbreiding vir ArcView ontwerp en geïmplementeer. Die resultaat is 'n eerste- weergawe MKBN-uitbreiding. Die uitbreiding brei ArcView se funksionaliteit uit om 'n beperkte versameling MKBN-metodes in te sluit. Die nuut ontwikkelde funksies word geïllustreer aan die hand van twee probleme wat die ontwikkeling van die toerismepotensiaal vir die Coutada 16 Wildreservaat in Mosambiek aanspreek. Die uitbreiding maak voorsiening vir 'n MKBN-evaluasie van geografiese probleme en besit die vermoë om beide vektor- en roosterdata te analiseer. Hierdie stelsel verskaf 'n generiese omgewing vir probleemoplossing wat gebruik kan word om byna enige geografiese probleem te analiseer. Die studie identifiseer verbeteringe op en uitbreidings van die ontwikkelde funksies en slaag daarin om die potensiaal van probleemoplossing wat deur die integrasie van MKBN-tegnieke met ArcView moontlik gemaak word, te illustreer.

Thesis (MSc)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: Grazing management in the semi-arid communal areas of Namaqualand is investigated in this study. Paulshoek, situated in the Leliefontein Communal Reserve area, is delineated as the study area and consists of 20 OOOha.Cattle farming is practised by most households primarily on a subsistence basis. It is also used as a source of income when financial problems arise. The management of grazing-land in terms of formal rules and regulations is non-existent with only mutual relationships between farmers. The aim of this study is to develop a spatial framework for the management of a sustainable grazing regime with the aid of Geographic Information Systems (GIS) technology. This aim is reached through three overlapping goals which are researched individually. The goals are to create a spatial image of the physical resource base as well as resource usage and from this the development of a computerised (Excel spreadsheet) spatial management framework for sustainable grazing management. Through the use of existing data available from the National Botanical Institute (NB!) as well as other sources and with the aid of GIS technology, coupled with Indigenous Knowledge, these goals were reached. The stockpost as individual entity is studied to give a broader understanding of how the herdsmen see their immediate environment. The grazing management system, as presented in this thesis, consists of a simple Excel Spreadsheet, with inputs from GIS technology and Indigenous Knowledge. The area is overgrazed, as is seen in the widespread occurrence of kraalbos cross the Paulshoek landscape. The recommendations are that this management system should be implemented, which could minimize the futher overgrazing of the area. The management system relies heavily on the cooperation of the community and the integration of existing management systems and policies. It will give a more detailed account of who may own how many stock and where they may graze in the communal rangelands which will also help in the establishment of new permanent waterpoints in the area. / AFRIKAANSE OPSOMMING: Weidingsbestuur in die semi-ariede gemeenskaplike gebiede van Namakwaland is in hierdie studie ondersoek. Paulshoek, geleë in die Leliefontein Gemeenskapsreservaat gebied, word as studiegebied afgebaken en beslaan ongeveer 20 OOOha.Veeboerdery word deur meeste van die huishoudings primêr as bestaansboerdery beoefen. Dit word ook gebruik as 'n bron van inkomste wanneer finansiële probleme ondervind word. Die bestuur van weivelde in terme van formele reëls en regulasies is glad nie ter sprake nie, slegs onderlinge verhoudinge tussen veeboere bestaan. Die doel van hierdie studie is om 'n ruimtelike raamwerk te ontwikkel vir die bestuur van 'n volhoubare weidingsregime deur die aanwending van Geografiese Inligting Stelsels (GIS). Hierdie doel word behaal deur drie oorkoepelende doelwitte wat elk afsondelik behandel word. Die doelwitte is om 'n ruimtelike beeld van die fisiese hulpbronbasis asook die benuttingsregime van die hulpbron te skep, en hieruit 'n rekenaar-gesteunde (Excel sigblad) ruimtelike bestuursraamwerk vir volhoubare weidingsbestuur te ontwerp. Deur gebruik te maak van bestaande inligting afkomstig vanaf Nasional Botaniese Instituut (NBI) asook ander bronne en met die koppeling van GIStegnologie en Inheemse Kennis (IK) is die doelwitte bereik. Die veepos word as entiteit behandel om 'n beter verstandhouding op te bou van hoe die veewagter sy onmiddelike omgewing bestuur. Die weidingsbestuurstelsel, soos voorgestel in hierdie tesis, bestaan uit 'n eenvoudige Excel sigblad, gekoppel aan GIS-tegnologie en Inheemse Kennis. Die gebied is oorbeweid, soos gesien kan word aan die verspreiding van kraalbos regoor die landskap van Paulshoek. Die aanbevelings is dat die bestuurstelsel geïmplementeer moet word om te verhoed dat die gebied verder onderhewig sal wees aan intensiewe beweiding. Die bestuurstelsel berus op die samewerking van die gemeenskap en die integrasie van bestaande bestuurstelsels. Dit sal tot gevolg hê 'n meer volledige opname van wie hoeveel vee mag besit en wie waar mag vestig in die weiveld gebied, wat gevolglik ook die skepping van nuwe permanente waterbronne sal vergemaklik.

Thesis (MA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: European cities offer a variety of attractions, activities and facilities to tourists. One component of tourism in this urban context is cultural tourism which is a high potential growth sector within the tourism industry. Cultural tourists travel to cities mainly to see the most important and well known cultural attractions, to take part in cultural festivities, to view the cultural treasures of the cities and to attend performances and exhibitions. Other functions and activities such as retail functions and types also occur in the vicinity of the important cultural attractions of a city. Amongst these activities and functions are shops, cafés and restaurants. In an area of a city where cultural attractions and retail types coexist, the possibility exits that a spatial relationship between cultural tourism and retailing may occur in the sense that the tourists who visit these attractions may support the retail establishments in the vicinity of cultural attractions. The city of Leuven in Belgium is a typical West European city with a variety of cultural tourist attractions as well as functions which can be supportive of cultural tourism. These functions include shops, cafés and restaurants. An investigation was conducted to establish whether a spatial relationship exists between cultural tourism and retail activities in the part of Leuven known as the Ring. The geographical information systems TransCad, Arc/Info en ArcView were used for the processing and analysis of retail and cultural tourism data gathered in the Ring of Leuven. Three analytical procedures were performed separately for shops, cafés and restaurants. These procedures comprised (a) the determination of the numbers and types of supportive functions around the most important cultural-historical tourist attractions, (b) the determination of the numbers and types of supportive functions along the routes to cultural-historical sites from tourist points of origin, and (c) the determination of the numbers and types of supportive functions along guided-walk routes in the city. The analysis results show that a (spatial) relationship does exist between retail and cultural tourism in the Ring of Leuven. On average 44% of the retail functions (shops, cafés and restaurants) are located within a distance of up to saam from the six most important cultural building attractions in Leuven (procedure 1). Retail functions on guided-walk routes totalled 48% with cafés and restaurants being the most abundant (procedure 3). Only 19% of retail functions are located between points of origin and cultural building attractions (procedure 2). A more detailed study should be conducted to establish the exact nature of the spatial relationship which exists between retail and cultural tourism in the Ring of Leuven. / AFRIKAANSE OPSOMMING: Europese stede bied 'n reeks attraksies, aktiwiteite en fasiliteite vir toeriste. Een komponent van die breër term toerisme in hierdie stedelike konteks is kulturele toerisme wat 'n baie sterk groeisektor binne die toerismemark is. Kulturele toeriste besoek stede hoofsaaklik met die doelom die belangrikste en bekendste kulturele attraksies te besigtig, om aan kulturele feeste deel te neem, die kunsskatte van stede te betrag en om teateropvoerings en tentoonstellings by te woon. In die nabyheid van die belangrikste kulturele attraksies van 'n stad kom ook ander funksies en aktiwiteite soos kleinhandelsfunksies en -tipes voor. Hieronder ressorteer onder andere winkels, cafés en restaurante. In die gedeelte van 'n stad waar kulturele attraksies en kleinhandelstipes naby mekaar voorkom, kan die moontlikheid bestaan van 'n ruimtelike verwantskap tussen kulturele toerisme en kleinhandel, in dié sin dat toeriste wat die attraksies besoek, moontlik ook die kleinhandelstipes wat in die nabyheid van die kulturele attraksies voorkom, salondersteun. Die stad Leuven in België is 'n tipiese voorbeeld van 'n Wes-Europese stad met 'n verskeidenheid kulturele toeriste-attraksies asook funksies wat kulturele toerisme ondersteun. Hierdie ondersteunende funksies sluit winkels, cafés en restaurante in. In die deel van Leuven wat as die Ring bekend staan, is ondersoek ingestel na die voorkoms, al dan nie, van 'n ruimtelike verwantskap tussen kulturele toerisme en kleinhandel. Die geografiese inligtingstelsels TransCad, Arc/Info en ArcView is ingespan vir die verwerking en analise van data oor kleinhandel en kulturele toerisme in die Ring van Leuven. Drie ontledingsprosedures is afsonderlk uitgevoer vir winkels, cafés en restaurante. Hierdie prosedures behels (a) die bepaling van die aantal en tipes ondersteunende funksies rondom die belangrikste kultuurhistoriese toeristeattraksies; (b) die bepaling van die aantal en tipe ondersteunende funksies langs die roetes tussen die toeriste-oorsprongpunte en die belangrikste kultuurhistoriese toeriste-attraksies; en (c) die bepaling van die aantal en tipe ondersteunende funksies langs begeleide stadswandelroetes. Die analiseresultate wys dat 'n verwantskap tussen kleinhandel en kulturele toerisme, ruimtelik-gesproke, wel in die Ring van Leuven bestaan. Só is gemiddeld 44% van die kleinhandelsfunksies (winkels, cafés en restaurante) tot op In afstand van SOOmvanaf die ses belangrikste kulturele gebou-attraksies in Leuven geleë (prosedure 1). Ook kom 48% van die kleinhandelsfunksies langs die roetes van begeleide stadswandelinge voor. Hier is dit egter die cafés en restaurante wat die grootste proporsies uitmaak (prosedure 3). 'n Gemiddelde proporsie van slegs 19% van die kleinhandelsfunksies kom tussen oorsprongpunte en die belangrikste kulturele gebou-attraksies voor. 'n Meer omvattende studie moet onderneem word om vas te stel watter tipe ruimtelike verwantskap tussen kleinhandel en kulturele toerisme binne Leuven se Ring voorkom.

Thesis (MA.)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: There are many reasons to conserve fynbos. Not only does fynbos form part of the Cape floral kingdom, one of the richest floral kingdoms in the world, but the contribution that it makes to the regional economy through utilisation, education, recreation and tourist opportunities is immeasurable. Fire plays an integral role in fynbos ecosystems. According to Van Wilgen, Richardson & Seydack (1994: 322) " ... managing fynbos equates to managing fire". Therefore managers need accurate fire information about a fynbos area to manage it properly. This is where satellite remote sensing can provide the manager with useful information about the fire regime. In other words, satellite remote sensing can help a manager establish where and when an area has burnt. Using readily available satellite data, this study attempts to establish (through comparison) what techniques would be most suitable and affordable to compile a fire information database. Landsat Thematic Mapper data from 1990 - 1996 of the southwestern Cape was used and compared with existing fire records of the area. The results show that techniques such as supervised and unsupervised classification are reliable in identifying burnt areas, but a major drawback of these techniques is that they require a large amount of user input and knowledge. They are thus not regarded as simple or easily repeatable. - The' more simple techniques like image differencing and image ratioing were also found to be reliable in identifying burnt areas. These techniques require less user input and in some instances less data (image bands) to produce similar (or better) results than supervised and unsupervised classification techniques. The results show that differencing temporally different Images, obtained from applying principle components analysis, produces reliable results with very little confusion and little user input. Using such a technique could enable users to procure only two bands of Landsat data and still produce reliable fire information for managing a fynbos ecosystem. / AFRIKAANSE OPSOMMING: Daar is verskeie redes waarom fynbos bewaar moet word. Nie net vorm dit deel van een van die rykste blommeryke in die wereld nie, maar die bydrae wat dit tot die streeksekonomie maak, deur die benutting van veldblomme en die geleenthede wat dit bied vir toerisme en ontspanning, is enorm. Vuur speel 'n belangrike rol in die bestuur van fynbos ekosisteme. Soos beklemtoon deur Van Wilgen, Richardson & Seydack (1994: 322) se stelling: " ... managing fynbos equates to managing fire". Om hierdie rede is dit belangrik dat 'n bestuurder akkurate inligting oor die verspreiding van veldbrande moet he. Satellietafstandwaarneming kan hier 'n belangrike rol speel deur sulke inligting te verskaf Deur gebruik te maak van maklik bekombare satellietdata, poog hierdie studie om te bepaal (d.m.v. vergelyking) watter tegnieke die mees geskikte is in terme van bekostigbaarheid en gebruikersvriendelikheid. Landsat Thematic Mapper data van 1990 tot 1996 van die suidwes-Kaap is gebruik en vergelyk met bestaande branddata van die studiegebied. Daar is gevind dat tegnieke soos gerigte en nie-gerigte klassifikasie in staat is om gebrande dele betroubaar uit te ken. Hierdie tegnieke verg egter baie insette en kennis van die gebruiker en is ook nie maklik om jaar na jaar te herhaal nie. Daarom word hierdie tegnieke nie aanbeveel nie. Daar is gevind dat die eenvoudiger tegnieke soos veranderingsanalise ook gebrande dele betroubaar kon uitken. Hierdie tegnieke het die voordeel dat die gebruiker nie baie' kennis van die gebied hoef te he nie en ook nie so baie insette hoef te lewer nie. Hierdie tegnieke word bo gerigte en nie-gerigte klassifikasie aanbeveel. - Die resultate dui daarop dat betroubare resultate verkry kan word deur tempo reel verskillende beeIde, verkry deur hoofkomponentanalise, van mekaar af te trek. Hierdie tegniek vereis relatief min gebruikersinsette en daar kan selfs met slegs twee Landsat bande gewerk word. So 'n tegniek kan beslis 'n bekostigbare en effektiewe manier wees om nodige inligting vir die bestuur van 'n fynbos ekosisteem te bekom.
