Geographic Information Systems (GIS) education in South Africa and elsewhere has been envisioned to be a strategy that can contribute to new ways of teaching, learning and understanding. However, very few studies have assessed how GIS is taught in South African high schools. Consequently, this study aims to analyze GIS education dynamics and perspectives in uMgungundlovu District, KwaZulu-Natal Province, South Africa. A survey with both open and close-ended questions was conducted with geography educators and geography students. Questions focused on GIS content, how the content is taught, challenges in GIS education, educators’ GIS proficiency and GIS education perspectives. The sample was guided by purposive sampling that intentionally selected schools with the desired qualities. From the results, it was evident that GIS is progressively taught in secondary schools. However, the full potential of GIS education has been restricted by challenges such as inadequate resources and limited exposure of students to GIS’s practical uses. Subsequently, the study recommends that GIS education in South African schools should be accompanied by appropriate hardware, software and opportunities for exposing students and educators to practical methods of teaching and learning GIS. Furthermore, educators should also be trained to be able to adequately equip students with GIS skills and knowledge.

IntroductionDespite progress towards the Joint United Nations Programme on HIV/AIDS 95-95-95 targets, South Africa is still suffering from one of the largest HIV epidemics globally. In this study, we generated high-resolution HIV prevalence maps and identified people living with HIV (PLHIV) in underserved areas to provide essential information for the optimal allocation of HIV-related services.MethodsThe data come from the South Africa Demographic and Health Survey conducted in 2016 and spatial variables from other published literature. We produced high-resolution maps of HIV prevalence and underserved areas, defined as a greater than 30 min travel time to the nearest healthcare facility. Using these maps and the population density, we mapped PLHIV and the PLHIV within underserved areas for 30, 60 and 120 min thresholds.ResultsThere was substantial geographic variation in HIV prevalence, ranging from 1.4% to 24.2%, with a median of 11.5% for men, and from 2.1% to 48.1%, with a median of 20.6% for women. Gauteng province showed the highest density for both HIV prevalence and PLHIV. 80% of all areas in the country were identified as underserved areas (30 min threshold), which contained more than 16% and 20% of the total men and women living with HIV, respectively. KwaZulu-Natal province had the largest number of PLHIV in underserved areas (30 min threshold) and showed less than one healthcare facility per 1000 PLHIV.ConclusionOur study showed extensive spatial variation of HIV prevalence and significant numbers of PLHIV in underserved areas in South Africa. Moreover, we identified locations where HIV-related services need to be intensified to reach the ~1.5 million PLHIV in underserved areas, particularly in KwaZulu-Natal province, with less than one healthcare facility per 1000 PLHIV.

PURPOSE The purpose of the study was to explore the key stakeholders’—health care professionals, patients, and family caregivers—experiences of providing, receiving, and setting priorities for lung cancer care in KwaZulu-Natal, South Africa, with a view to propose potentially effective interventions for improved care. METHODS This was a qualitative study conducted in 5 communities and 3 hospitals offering oncology services in KwaZulu-Natal Province. Data were generated using in-depth interviews and the nominal group technique. Nineteen patients with lung cancer, 20 family caregivers (FCs) and 18 health care professionals (HCPs) were interviewed, with an additional subsample of 7 HCPs participating in the nominal group technique. Results were analyzed using thematic analysis. RESULTS Similar to patients with lung cancer and FCs, HCPs were concerned about the limited access to oncology services and poor lung cancer diagnostic facilities, as these also ranked high in HCPs’ priority settings. Limited access was attributed to a lack of lung cancer awareness and low lung cancer suspicion index among different stakeholders, a shortage of health care specialists, poor diagnostic equipment and general resource constraints, unavailability of diagnostic services at the lowest levels of health care (for example, primary health care), geographic location of specialized services, and poor multidisciplinary collaboration. Patients’ perceptions of the quality of care in public health facilities also affected their treatment-seeking behavior. Challenges experienced at the health care worker-patient level also affected the FCs. For example, FCs were psychosocially and economically affected by the caring responsibilities, which, in turn, was an important determinant of a patient’s care pathways. CONCLUSION As a result of this study, new approaches to lung cancer care are being explored, including increased community awareness, the introduction of well-equipped community mobile screening services, patient navigation to track patients, and building cadres for providing and integrating palliative care services into the mainstream health systems.

The study identified constraints faced in a livestock development programme and their determinants. The study utilised a questionnaire, administered purposively on farmer field days in November, 2017, through a cross sectional survey of KyD scheme participants from KwaZulu-Natal Province, South Africa, with a purposive sample of 164 respondents from 3 locations. The data was analysed through descriptive statistics, Likert scale and binary logistic regression. The results show that the constraints faced include lack of sense of ownership, information, extension commitment and lack of leadership. Furthermore, lack of sense of ownership was determined by access to veterinary services, experience in rearing cattle, land tenure and the decision maker. Determinants of commitment of extension worker constraint were gender of household-head as well as the decision maker, whilst for lack of information were monthly off-farm income, land tenure, decision maker as well as source of income. Conclusions reached include overreliance on scheme services, and complexities in decision making having bearing on the constraints faced in the KyD scheme. The study recommends incorporating indigenous knowledge systems which have tier effect of increasing access to services, farmer’s participation and decision making, also taking advantage of the relationships with extension services to enhance effective information dissemination.

Rural women in South Africa are important role players in community development; to withhold information from them is to hold back the potential for rural development. However, obstacles such as poverty, illiteracy, fear, poor access to public agencies, and lack of knowledge about the right to information and how or where to ask for it has deprived women of access to information. Since post-apartheid South Africa, government has made progress toward empowering women. Community radio is the only accessible and readily affordable medium within the rural community and can play a significant role in rural development of women. This article adopts the case study research approach through the use of document analysis and interviews to investigate the role of two community radio stations in selected areas of the KwaZulu-Natal Province of South Africa with regard to rural development and the dissemination of information to women listeners. It also suggests ways by which these radios may be used to enhance access to information by rural women in South Africa. The findings reveal that although community radio stations are recognised as support systems for information dissemination in rural communities, their role in information dissemination and the community development of women has not been fully explored. This article suggests ways in which the services of community radios may be enhanced by the provision of information to women for rural development.

<p><strong>Background.</strong> Low- and middle-income countries carry the major burden of mental disorders, yet owing to a significant lack of resources, they experience a ‘treatment gap’ in the range of 75 - 85%.</p><p><strong>Methods.</strong> Epidemiological data on mental disorders in South Africa, national census data and locally developed models for establishing treatment needs were used to calculate expected annual acute admissions and inpatient care, as well as expected annual ambulatory visits in KwaZulu-Natal (KZN) Province, South Africa. These were compared with actual acute admission and inpatient care rates as well as actual ambulatory visits to mental health services in the province, derived from the District Health Information Systems. These comparisons allowed an estimation of the treatment gap for mental disorders in the province.</p><p><strong>Results.</strong> Approximately 956 000 adults were estimated to live with mental disorders in KZN. Only 19.8% (10 620) of expected admissions (53 623) took place during the one-year reporting period; while the total number of acute inpatient days accounted for 26.1% of the expected number. Average length of stay (ALOS) for acute admissions was longer (21 days) than the expected ALOS (16 days). At the recommended level of 30% coverage, ambulatory visits to mental health facilities accounted for 21% of the expected visits during the one-year period.</p><p><strong>Conclusion.</strong> In keeping with previous estimates, these results provide evidence that the ‘treatment gap’ for acute inpatient and ambulatory mental healthcare in KZN is ~80%. This rate is similar to the estimated mental health resource gap in the province, suggesting that gross inadequacies in mental health service provision translate directly into major unmet needs for those living with mental disorders.</p>

This study investigated the impacts of cultivation on water and soil quality in the lower uMfolozi floodplain system in KwaZulu-Natal province, South Africa. We did this by assessing seasonal variations in purposefully selected water and soil properties in these two land-use systems. The observed values were statistically analysed by performing Student’s paired t-tests to determine seasonal trends in these variables. Results revealed significant seasonal differences in chloride and sodium concentrations and electrical conductivity (EC) and the sodium adsorption ratio (SAR) with cultivated sites exhibiting higher values. Most of the analyzed chemical parameters were within acceptable limits specified by the South African agricultural-water-quality (SAWQ) water quality guidelines for irrigation except for sodium adsorption ratio (SAR), chloride, sodium and EC. EC, pH and nitrate content which were higher than the specified SAWQ limits in cultivated sites. Quantities of glyphosate, ametryn and imidacloprid could not be measured because they were below detectable limits. The study concludes that most water quality parameters met SAWQ’s standards. These results argue for concerted efforts to systematically monitor water and soil quality characteristics in this environment to enhance sustainability by providing timely information for management purposes.

ENGLISH ABSTRACT: This study aimed to understand how Dukuduku Forest in Kwa-Zulu Natal has changed from 1960 to 2008 and whether the change in political regimes, during and post apartheid eras might have contributed to changes in forest extent. To achieve the aims, the following analyses were made: - Qualitative and quantitative spatial analyses of forest change; - Analyses of the correspondence of change with political changes in the country; - Assessment of perception of people living in the Dukuduku forest area. The Dukuduku land cover was mapped from aerial photos using ArcGIS 9.3 to determine whether or not there has been a significant change in the area from 1960-2008, in response to resource use pressures and to come up with the strategic sustainable management plan from the results found. Five aerial photographs were used to determine the changes in land cover from the year: 1960, 1970, 1992, 2005 and 2008. The Land cover types were classified into four classes, Indigenous Forests, Plantation Forests, Water Bodies and Other (open areas, cultivated land, and all the human disturbed and transformed land). The percentage of cover per class was compared across the years to determine overall change in land cover and the rate of change per year was also calculated. The results from the study showed that: - Natural Forest increased by 11% (700 ha), at the rate of 20.56 hectares per year between 1960 and 1992, which is the apartheid era. Between 1992 and 2008, the democratic era, the forest decreased by 34.4% (2472.31ha), at the rate of 168 hectares per year. - The Dukuduku forest community gains resources (timber and grass for construction, art, firewood, medicinal plants, grazing of livestock and food) from the forest. The people are willing to contribute in protecting the forest only if the governing authorities would include them in decisions made, as the NFA demands Participatory Forest Management, but which does not currently exist in Dukuduku.
AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die verandering van die Dukuduku woud in Kwa-Zulu Natal vanaf 1960 tot 2008, en vernaamlik of die verandering in politieke regimes tydens en in die postapartheid eras tot verandering bygedra het in die woud se vorm. Om hierdie doelwitte te breik is die volgende analises gedoen: - Kwalitatiewe en kwantitatiewe ruimtelike analises van woudverandering; - Analises van die korrelasie tussen hierdie fisiese omgewingsverandering en politieke verandering in die land; - Analise van die persepsie van mense wat in die Dukuduku woudgebied woon. Die Dukuduku gronddekking is gekarteer met behulp van lugfotos, waarvoor ArcGIS 9.3 gebruik is om te bepaal of daar noemenswaardige verandering in die gebied plaasgevind het van 1960 tot 2008, in reaksie op hulpbrongebruike, en om ‘n volhoubare bestuursplan gestel voor wat op die bevindinge gebaseer is. Vyf lugfotos is gebruik om verandering in gronddekking te bepaal vir die jare: 1960, 1970, 1992, 2005 en 2008. Die Gronddekking tipes is geklassifiseer in vier klasse naamlik Inheemse Woude, Plantasiebosse, Waterliggame en Ander (oop gebiede, landerye en al die mens-versteurde en getransfomeerde gebiede). Die persentasie van elke dekkingsklas is oor die jare vergelyk om die verandering in algehele grond-dekking te bepaal, en die tempo van verandering is ook bepaal, asook die tempo van verandering. Die resultate van die studie wys dat: - Die natuurlike woud toegeneem het met 11% (700 ha), teen ‘n tempo van 20.56 hektaar per jaar tussen 1960 en 1992, tgedurende die apartheidsera. Tussen 1992 en 2008, die demokratiese era, het die woude verminder met 34.4% (2472.31 ha), teen ‘n tempo van 168 hektaar per jaar. - Die gemeenskap wat in die Dukuduku woud woon verkry hulpbronne van die woud (hout en gras vir konstruksie, kuns, brandhout, medisinale plante, weiding vir vee, en voedsel). Die mense is gewillig om by te dra tot beskerming van die woud indien die owerhede hulle sou betrek in besluite wat geneem word, veral omdat die nasionale Wet op Bosse voorsiening maak vir Deelnemende Bosbestuur, wat tans nie by Dukuduku gebeur nie.

Background to the academic research. Hilton College is an all boys private school in the Kwa-Zulu Natal Midlands. Since the beginning of 2012 boys have been permitted to carry their phones during the school day, (Thomson, 2012). Wireless internet access was also extended across the campus to allow boys and staff to bring their own devices to class and have access to the internet (Machlachlan, 2012). In the past, communication between staff and boys was either verbal or through the use of a daily notice, called the Daily Routine Order (DRO). The DRO is placed at the dining room tables each day and boys are expected to check for any notices that may pertain to them. These notices are emailed to a secretary who prints them out and places them in the dining room each day at lunch. 2. Objectives to the research. This research sought to establish whether current communication methods were effective or whether the prevalence of mobile phones and wireless devices had presented the school with a more effective method. It was important therefore, to investigate what devices were on campus, how those devices were used and when they were used. In addition to this, the research sought to establish communication preference among staff and boys. 3. Research Methodology. The research was conducted through the use of a qualitative survey that was conducted among both staff and boys. Staff and boys were surveyed to establish generation, device prevalence, device usage and device preference. This data was collected using an anonymous qualitative survey that was administered through the use of Google docs in the school labs. 187 Boys in 3 grades 8 and 9 participated in the survey along with 18 staff members. The data was then analysed and compared to data from similar research that had been conducted elsewhere in the world. Because of significant age differences between boys and staff it was critical to establish whether device usage among staff and boys was tied to their generation. Of particular interest were the device behaviours associated with the Millennial generation, who were born between 1982-2002 (Strauss 2005:10). This generational ‘benchmark’ allowed the researcher to compare the Hilton College cohort to those whose device behaviours and usage had occurred and been discussed in generational research elsewhere. It also allowed for certain assumptions to be made about staff and boys based on their generational profile. 4. Findings It was found that staff and boys exhibited communication traits that were consistent with their generation and consistent with other research in this field. It was also found that staff and boys preferred mobile and digital forms of communication over verbal announcements and the DRO system. For this reason, it was recommended that the Hilton College establish a system that took advantage of technology to improve on communication. Various recommendations were given by the researcher that took advantage of current technologies. These included the use of SMS, Instant Messaging, Social Networks and email. It was also recommended that the school consider prescribing devices that allow for communication between staff and boys.

ENGLISH ABSTRACT: The prevention of mother-to-child transmission (PMTCT) of HIV is a key maternal and child health intervention in the context of the HIV/AIDS pandemic in South Africa. Accordingly, the PMTCT programme has been incorporated in the District Health Management Information System (DHMIS) that collects monthly facility-based data to support the management of public health services. To date, there has not been a comprehensive evaluation of the PMTCT information system. By comparing the experiences in two health districts, using the Performance of Routine Information System Management (PRISM) framework and tools, this study seeks to evaluate the availability, quality and use of process and output indicators for monitoring PMTCT interventions. A comparative analytical and observational study was undertaken using a multi-method approach which included: a self-administered survey of health information personnel to assess confidence and competence levels for routine health information system (RHIS) tasks, an assessment of the routine PMTCT data for quality, completeness, accuracy, and data use; and a facility survey of RHIS processes and resources. In addition, in-depth interviews with 22 key informants and observations in health facilities were conducted. Data were collected from 57 health facilities in a convenience sample of two health districts, and also from 182 health information personnel in the 57 health facilities, three sub-districts, and two district offices. Descriptive statistics, χ2-test, correlation and multiple regression analyses were conducted using STATA® Version 13. A general inductive approach was also used to analyse the qualitative data, which was used for triangulation. The study revealed considerable data quality concerns for the PMTCT information with an average accuracy between the register and routine monthly report of 51% and between the routine monthly reports and DHMIS database of 84% suggesting that the primary point of departure for accurate transfer of data is during the collation process. The importance of human factors was emphasised by the observation that the average confidence level for performing RHIS-related tasks (69%) was not commensurate with the average competence levels (30%). Education was found to be associated with competence, implying that levels of education may be associated with the level at which RHIS competencies are acquired; and that three years or more of post-matriculation education is necessary. Motivation, on the other hand was not associated Stellenbosch University https://scholar.sun.ac.za iv with competence. The study observed the absence of processes such as data-quality checks and data-analysis in place in facilities. There was a general absence of a culture of information use, as a result of lack of trust in the data, and the inability of programme and facility managers to analyse, interpret and use information. We observed differences in the data accuracy by organisational authority, and multivariate analysis and qualitative information suggested that feedback may be an essential process to ensure quality. Although the PRISM framework has been developed from a multi-disciplinary evidence base, this study has been able to validate some of the internal assumptions but has also found some aspects that were not supported such as motivation and data display. Data collected from a larger number of facilities will be required to investigate this further. Institutional capacity to improve RHIS processes, ensure core competencies for RHIS-related tasks are needed, and in the longer term, measures to tackle problems associated with low pass rates in numeracy subjects among high school learners are needed. Further exploration of the possible factors that may influence data accuracy, such as supervision, training and leadership are needed as well as investigating the relationships between human and institutional agency-related aspects, in particular, how individual actions can bring about changes in institutional routines. Further study is needed to determine how decision for planning and evaluating key programmes such as PMTCT are made, and what informs such decisions if not routine data.
AFRIKAANSE OPSOMMING: In die lig van Suid Afrika se MIV/VIGS-pandemie kan ’n ingryping op gesondheidsvlak ’n belangrike rol speel om moeder-na-kind-oordrag (beter bekend as PMTCT) van MIV te voorkom. ’n Inligtingstelsel vir distriksgesondheidsbestuur – die DHMIS – was ontwerp vir die invordering van maandelikse fasiliteitsdata, wat gebruik kan word om die bestuur van openbare gesondheidsdienste en -programme te ondersteun. Die inligtingstelsel self was nog nie omvattend evalueer nie. Hierdie studie het die ervarings van twee gesondheidsdistrikte vergelyk met behulp van die PRISM- (Performance of Routine Information System) raamwerk en -instrumente. Derhalwe het hierdie studie die beskikbaarheid, gehalte en gebruik van proses- en uitsetaanwysers probeer bepaal om die PMTCT-ingrypings te monitor. ’n Vergelykende analitiese en waarnemingstudie is onderneem met behulp van ’n veelvuldige benadering. Die verskillende metodes het ’n selfopname onder gesondheidsinligtingspersoneel ingesluit om hul selfvertroue en bevoegdheid in roetinegesondheidsinligtingstelsel (RHIS)-take te evalueer. Daar was ook ’n assessering van die PMTCT-roetinedata om datagehalte, -volledigheid, -akkuraatheid en -gebruik te beoordeel.’n Fasiliteitsopname oor RHIS-prosesse en –hulpbronne was ook gedoen. Ander navorsingsmetodes het diepte-onderhoude met 22 sleutelpersone ingesluit, sowel as waarnemings in gesondheidsfasiliteite. Data is van 182 gesondheidsinligtingpersoneel van die 57 gesondheidsfasiliteite in ’n geriefsteekproef van twee gesondheidsdistrikte ingesamel. Deskriptiewe statistiek, χ2-toetsing, korrelasie en veelvoudige regressie is met behulp van STATA® weergawe 13 ontleed. ʼn Algemene induktiewe benadering is ook gevolg om die kwalitatiewe data te ontleed. Die studie toon dat menslike faktore ’n impak op datagehalte en -inligting kan hê, met ’n gemiddelde akkuraatheidsyfer van 51% van beide die register en roetine maandelikse verslae. Die akkuraatheid van die maandelikse verslae en RHIS databasis is 84%, wat aandui dat akkuraatheid slegs toegepas word indien inligting uit die staanspoor korrek aangeteken word. Die impak van menslike hulpbronafaktore was beklemtoon toe daar bevind was dat hoewel 69% van RHIS-dataverwerkers vertroue getoon het in die gebruik van RHIS-verwante take, slegs 30% wel bevoeg was om die werk te doen. Opvoeding was grootliks geassosieer met bevoegdheid, wat moontlik voorstel dat sekere vlakke van opvoeding benodig word vir spesifieke RHIS-bevoegdhede. Minsten drie jaar tersiêre opleiding word aanbebeel. Motivering was nie met Stellenbosch University https://scholar.sun.ac.za vi bevoegdheid geklassifeer nie. Die studie het bevind dat daar te min aandag aan datagehalte en –analise gegee word in fasiliteite. Oor die algemeen was daar nie ’n ordentlike kultuur van inligtinggebruik nie, a.g.v. die feit dat daar nie vertroue in die data was nie. Terselftertyd was program- en fasiliteitbestuurders nie bevoeg om inligting te analiseer en ontleed nie. Ons het verskille in die akkuraatheid van data opgetel wat deur organisasie-hoofde gedoen was. Meervoudige analise en kwalitatiewe informasie stel voor dat terugvoering ’n belangrike deel van die proses moet wees om kwaliteit te verseker. Hoewel die PRISM-raamwerk saamgestel was uit ’n multi-dissiplinêre bewyslewering, kon hierdie studie sommige van die interne voorneme valideer, maar daar was aspekte wat nie gestaaf kon word nie. Inligting van ’n groter aantal fasiliteite sal benodig word om verder hierna ondersoek in te stel. Institusionele kapasiteit word benodig om RHIS-prosesses te verbeter en basiese vaardighede vir RHIS-verwante take te verseker. Op langtermynvlak moet daar ook gekyk word na probleme wat lei tot laë slaagsyfers in syfervaardighede in hoërskoolleerders. Verdere ondersoek moet ingestel word om vas te stel watter faktore moontlik akkurate data teweeg kan bring. Dit sluit toesig, opleiding en leierskap, asook die verhoudings tussen menslike en agentskap-verwante aspekte in. Die feit dat optrede op individuele vlak veranderings in institusionele roetines kan aanbring, moet spesifiek na gekyk word. Verdere studies kan help om vas te stel hoe besluite vir beplanning en evaluaring vir hoofprogramme soos PMTCT gemaak word – asook hoe die besluite gemaak word indien hulle nie roetine voorafgaan nie.

The purpose of the study was to investigate the potential of Geographic Information Systems (GIS) in South African local planning. Planning is facing great challenges in contemporary South Africa and one of them is to consider new technologies to enable effective and efficient planning for the future. In meeting the overall aim of the study, a number of goals were set. The first goal was to provide an overview of GIS implementation in local governments from an international perspective. This goal was achieved by reviewing literature on the subject which encompassed the technology's evolution and factors affecting implementation. Practical examples were cited to demonstrate the application of GIS in planning. The second goal was to examine the role of GIS within the South African planning context. An investigation of the relevant legislation provided a context within which GIS could be implemented at the local level. In order to arrive at the second goal, a suitable planning process was derived from a review of applicable planning theory. The third goal was to illustrate practically how GIS could be implemented and integrated into the planning process at the local level. This goal was achieved by carrying out a project within the Pietermaritzburg suburb of Mountain Rise. The results of the case study showed that GIS has a potentially significant role to play in planning at the local level.

This research focused on adventure tourism in KZN. The adventurer traveller is interested in remote pristine hotspots. A concern is that irresponsible behaviour on the adventurer’s part could lead to the destruction of the fragile natural environment, as well as negatively interfere with the local traditional cultural values. Adventure hotspots were identified by using the functionalities of a GIS. These findings were validated by tourism practitioners in KZN. The researcher also proposed a practical solution that could improve or enhance the behaviour of adventurers. Existing media were collated into information prompts. These information prompts were categorised in tables that could be linked to a mobile GIS environment. The researcher then examined the framework requirements for a mobile GIS. This resulted in a set of seven criteria that brought together the core essentials required for the conceptual framework of a mobile GIS device dedicated to the adventurer in KZN.

The Wattled Crane, Bugeranus carunculatus Gmelin, is presently classified as being 'Critically Endangered' within South Africa according to the Eskom Red Data book of Birds of South Africa, Lesotho and Swaziland, with a population of a meagre 235 individuals. Of this, 85% occur within KwaZulu-Natal and live predominantly on privately owned agricultural land. As a result thereof, Wattled Cranes and agriculture compete for the same resources. Up until now, the loss of viable habitat, as a result of agricultural development and afforestation, has been mooted as being the primary reason for the decline in numbers of the species. The advancements in the Geographical Information Systems field have enabled conservationists to acquire data, especially pertaining to habitat requirements, which were previously unattainable. This improved data acquisition is enabling for more informed decision making and better allocation of resources. The study therefore attempts to make use of a Geographical Information System to determine whether or not differences exist within the home ranges of active and historical Wattled Crane nesting sites, utilising the National Land cover database. The updated Land cover data for South Africa, although not completed at the time the present study took place, allowed for the interrogation of the various Land cover classes within an estimated home range. Natural Grassland was the predominant Land cover type within both active and historical home ranges, whilst both active and historical home ranges were subject to some degree of transformation. The potential impact of management practices in and around nesting sites warrants further investigation because this could not be determined through the analysis of land cover.

Rapid growth of cities is a global phenomenon exerting much pressure on land resources and causing associated environmental and social problems. Sustainability of land resources has become a central issue since the Earth Summit in Rio de Janeiro in 1992. A better understanding of the processes and patterns of land cover change will aid urban planners and decision makers in guiding more environmentally conscious development. The objective of this study was firstly, to determine the location and extent of land use and land cover changes in the uMhlathuze municipality, KwaZulu-Natal, South Africa between 1992 and 2002, and secondly, to predict the likely expansion of urban areas for the year 2012. The uMhlathuze municipality has experienced rapid urban growth since 1976 when the South African Ports and Railways Administration built a deep water harbour at Richards Bay, a town within the municipality. Three Landsat satellite images were obtained for the years, 1992, 1997 and 2002. These images were classified into six classes representing the dominant land covers in the area. A post classification change detection technique was used to determine the extent and location of the changes taking place during the study period. Following this, a GIS-based land cover change suitability model, GEOMOD2, was used to determine the likely distribution of urban land cover in the year 2012. The model was validated using the 2002 image. Sugarcane was found to expand by 129% between 1992 and 1997. Urban land covers increased by an average of 24%, while forestry and woodlands decreased by 29% between 1992 and 1997. Variation in rainfall on the study years and diversity in sugarcane growth states had an impact on the classification accuracy. Overall accuracy in the study was 74% and the techniques gave a good indication of the location and extent of changes taking place in the study site, and show much promise in becoming a useful tool for regional planners and policy makers.

Rural farmers in the Nkwezela Area, with an average family size of 10 people, face a number of problems. The crops that are predominantly cultivated in the area, for subsistence (maize, dry beans, sorghum, potatoes, cabbages and turnips) have very low yields compared to the potential yield of the land. Natural resources in the area are increasingly deteriorating. In addition, arable land has shown remarkable signs of soil erosion that may lead to loss of soil fertility. This study evaluates the current land suitability for subsistence agriculture in Nkwezela based on climatic, soil, topographic and crop requirement data collected from different sources. The spatial parameters of the land resources were digitally encoded into a GIS database to create thematic layers of the land resources which was then compared to the crop requirement data of the selected crops grown in Nkwezela namely, maize, sorghum, dry beans, potatoes, cabbages and turnips. A GIS was used to overlay the thematic layers of the resources to select areas that satisfied the crop requirements of the selected crops. The results of the analysis of the land evaluation in the study area showed that the very hot summers, very cold winters together with the high clay content in the soils are the two limiting factors in Nkwezela. The land suitability maps indicate that sorghum is highly suitable in the area with dry beans and maize being relatively suitable. Cabbages are the least the least adapted crop with potatoes and turnips being not suitable due to the high temperatures during the growing season and the very cold winters. In conclusion Nkwezela is in a high rainfall area that is suitable for subsistence agriculture where warm season crops like dry beans, maize and sorghum are used for daily consumption by the community and can be cultivated in a sustainable manner. In addition the correct farming methods, procedures, liming and fertiliser requirements must be implemented, adhered to and maintained in order to improve crop yields in a sustainable manner and to encourage subsistence agriculture by the community.

This research applies the Near Repeat Calculator (NRC) to identify near repeat residential burglary patterns in the Hillcrest (KZN) policing area for the first time. A total of 490 residential burglaries, over a 12-month period, reported to Hillcrest police station were mapped (geocoded) and the near repeat calculations were visualised using the Geographic Information Systems (GIS). The month-to-month near repeat calculations are analysed and suggest that the NRC is a valuable tool that can predict the space-time locations of near repeat residential burglaries in the Hillcrest policing area.
Lolu cwaningo lusebenzisa i-Near Repeat Calculator (NRC) ukuhlonza amaphethini okuphindaphindeka kwezigameko zokugqekezwa kwamakhaya endaweni eyenganyelwe yisiteshi samaphoyisa sase-Hillcrest (KZN). Izigameko zokugqekezwa kwamakhaya ezingama-490 ezabikwa esiteshini samaphoyisa sase- Hillcrest esikhathini esiyizinyanga eziyi-12 zaboniswa emfanekisweni webalazwe lendawo (geocoded) futhi izilinganiso zamathuba okuthi ziphinde zenzeke izigameko zokugqekezwa kwamakhaya zaboniswa ngokuthi kusetshenziswe umfanekiso owenziwe nge-Geographic Information Systems (GIS). Kwahlaziywa amathuba enyanga nenyanga okuphindaphindeka kwezigameko, futhi imiphumela eyatholakala kulokhu iyabonisa ukuthi i-NRC iyithuluzi eliwusizo impela elingabikezela izindawo nesikhathi lapho kungaphinda futhi kwenzeke khona izigameko zokugqekezwa kwamakhaya endaweni eyenganyelwe yisiteshi samaphoyisa sase-Hillcrest.
Olu phando lusebenzisa uhlobo lokubala olwaziwa ngokuba yiNear Repeat Calculator (NRC) ngenjongo yokubona isimbo sokuqhekezwa kwezindlu zabantu kummandla ophantsi kwamapolisa aseHillcrest (eKZN). Kuqwalaselwe ama-490 eziganeko zoqhekezo lwemizi ezaxelwa emapoliseni aseHillcrest kwisithuba seenyanga ezili-12, kwaye uhlobo lokubala oluqikelela ukuphindwa kweziganeko zoqhekezo luboniswe ngokusebenzisa inkqubo ekuthiwa yiGeographic Information Systems (GIS). Ubalo oluqikelela ukuphindwa kweziganeko luphononongiwe kwinyanga nenyanga, kwaye iziphumo zibonisa ukuba iNRC sisixhobo esinexabiso, esinokukwazi ukuqikelela indawo nexesha apho kunokuphinda kuqhekezwe khona kummandla ophantsi kwamapolisa aseHillcrest.

Organisations are being forced to invest heavily in the deployment of information systems (IS) to obtain value and benefit in the new knowledge-based environment. Organisational intranets are being used as the platform for developing and deploying critical business applications to support business operations and managerial decision-making across the Internet-worked enterprise. Executive Information Systems (EIS) grew out of the information needs of executives. Web-based technologies are causing a revisit to existing information technology (IT) implementation models, including those for EIS. Some technologies include intranet, Internet, extranet, e-commerce business-to-business (B2B), e-commerce business-to-consumer (B2C), wireless application protocol (WAP), including other mobile technologies. The author conducted a survey of 31 well-established organisations in KwaZulu-Natal, South Africa, which successfully implemented EIS. A validated survey instrument was administered to an EIS stakeholder in each organisation surveyed to rank Web-based technologies in order of their perceived impact on EIS implementation in organisations surveyed. The author reports that an organisational intranet has the highest level of impact on EIS implementation in organisations surveyed in KwaZulu-Natal, South Africa. Given this impact, justifying investment in such IS and IT should be carefully evaluated and quantified.

Second Life (SL), an advanced virtual world technology used in education, creates an environment that facilitates engagement, collaboration, and conceptualization of knowledge to improve teaching and learning. The chapter investigates the potential of SL as a learning platform and students' perceptions on the ease of use of SL and usefulness as a learning platform, and challenges with SL implementation. The chapter adopts the qualitative research method, the Technology Acceptance Model, and a purposive sample drawn from fourth year Information Systems and Technology (IS&T) students at the University of KwaZulu-Natal in South Africa. The chapter reports that SL is perceived to be a useful learning platform by students and improves students' instinctive and creative learning ability. However, inadequate training and insufficient information technology (IT) infrastructure are the challenges that hamper SL implementation efforts. Thus, the chapter suggests adequate training, provision of infrastructure and creation of a support pathway for SL as a learning platform as the possible solutions.
