There remain vast knowledge gaps in the global south as to how tourism will affect climate change and vice versa. Recent extreme weather events in southern Africa attributed to climate variability and change have led to speculation that, the Victoria Falls, is under threat from climate change. This research was aimed at examining the two-way linkage between tourism and climate change. The research adopted a pragmatism paradigm in a mixed-method case study. A number of research techniques were used to investigate the problem, namely: an online survey (n=427), secondary data analysis, field observation and interviews. Data analysis was done making use of Mann-Kendall Trend Analysis, QuestionPro analytics, Microsoft Excel Analysis Toolpak, Tools from ArcMap 10.3.1 and SPSS 24. Content analysis and thematic analysis was used to analyse secondary and interview data respectively. It emerged that the Victoria Falls is experiencing climate change, which resulted in statistically significant increase in temperature over the past 40 years of between 0.3°C and 0.75°C per decade. However, no significant changes in rainfall were noted, although there has been a seasonal shift in average rainfall onset. Weather extremes and annual rainfall point to increased occurrence and severity of extreme years of droughts and wetting which has in turn also affected waterflow regime at the waterfalls. The changes have a negative impact on wildlife, tourists, and tourism business in the area. The study also revealed that tourism is an equally significant driver of climate change through carbon emissions throughout its value chain. Carbon emissions from tourism value chain are set to increase in the foreseeable future despite efforts of going green by the industry owing to exponential growth of the industry. There is, therefore, a need for the industry to adapt, mitigate and intensify green tourism efforts to achieve sustainability. The study further suggests that there is a need for better communication and education to build resilience and capacity for the tourism industry to deal with climate change. Further research is suggested to ascertain the tourism threshold for the area, impact of climate change on wildlife and basin changes that led to water flow increase in the Zambezi River. / Environmental Sciences / Ph.

The exotic plant Lantana camara L. has invaded the riparian areas of the Victoria Falls World Heritage Site in Livingstone, southern Zambia, threatening native plant communities which support populations of species of special concern. I trialled the mechanical control method of manual uprooting and 3 different herbicides applied through paint brushing of an imazapyr concentrate at 250g. l¯¹, spraying on cut stumps with metsulfron methyl at 600g.l¯¹, and foliar spraying on re-emergent lantana foliage with glyphosate at a dosage of 166g. l¯¹ in July 2008 in 20 100m2 treatment plots, 5 invaded control plots and 5 uninvaded controls. Follow-up treatments for re-sprouting lantana stumps and emerging seedlings were undertaken in June 2009. I measured effectiveness of the methods using adult lantana mortality in June 2009 and lantana seedling density in the different treatment plots during the follow-up exercise. The cost of the various methods and human labour applied were compared across the four treatments at initial clear and at follow-up. All treatments recorded a high adult lantana mortality rate, though there were no significant differences in lantana adult mortality amongst the treatments. Overall, uprooting had the highest adult mortality, followed by imazapyr, metsulfron and lastly glyphosate. Germination of lantana seedlings after clearing was high for all treatments but with no significant differences occurring between the treatments. Both adult lantana mortality and seedling density were however significantly different from the control. With labour included, chemical costs were far higher relative to uprooting, though uprooting costs were the highest when it came to the follow-up because of the emerging seedlings and some resprouting stumps. The effects of mechanical and chemical treatments on vegetation composition in the cleared areas were also assessed in order to detect any non-target and medium term effects of treatments. Contrary to expectation, none of the chemicals showed any significant effects on vegetation composition in the short and medium-term and no significant differences were found in plant species richness, diversity and seedling density between invaded and uninvaded plots at baseline, in October 2008 and in September 2009. In order to determine potential for unaided vegetation recovery in the riparian areas of the study site after lantana clearing, I conducted an investigation of soil seed banks and seed rain using 60 seed bank samples measuring 1800m³ collected from 30 invaded and uninvaded plots. Using the seedling emergence method, 1, 991 seedlings belonging to 66 species representing 27 families germinated from the seed bank. Sedges (Cyperaceae family) were the most abundant taxa in the seed banks from invaded areas, followed by Ageratum conyzoides, lantana, Triumfetta annua and Achyranthes aspera which also occurred in the uninvaded soil seed banks. The seed banks from uninvaded plots were dominated by the grass Oplismenus hirtellus. Overall, species richness, diversity and seedling density from seed banks in invaded areas did not differ significantly from seed bank in uninvaded areas and there was a low similarity in species composition when above ground vegetation was compared to seed banks from invaded and uninvaded areas. It would appear if natural regeneration occured from the current seed bank in disturbed areas, future vegetation would largely comprise of short lived, early successional species in the short term as the seed bank is dominated by non-native herbaceous weedy species. From the seed traps investigating seed rain, a total of 27 species numbering 623 individual seeds were found in the thirty 1m² seedtraps distributed in invaded and uninvaded areas at the five sites, over an intermittent period of three months. Lantana had the highest monthly arrival rate in the seed traps followed by Phoenix reclinata and Ricinus communis. The number of species with invasive potential found in the seed traps located in invaded areas was more than that found in seed traps under native vegetation cover by far. Considerable forest remnants still occur around the invaded sites, and these could serve as an important source for long-term natural re-establishment of native vegetation if seed availability by animals and wind dispersal continues, while the re-invasion of lantana is prevented by ongoing follow-ups and futher clearing of lantana invaded areas. It is concluded that while uprooting and other treatments are effective in the control of lantana, its successful control in the Victoria Falls World Heritage Site will require extensive clearing to keep it from reinvading infested areas after clearing as shown by the seed rain data. The high seedling density of lantana in the seed banks and in the cleared areas shows the need for ongoing follow-up in order to deplete soil stored seed banks. There is need for longer term research to establish what the exact follow-up requirements are in order to contain lantana re-infestation and create favourable micro-sites for native species to establish. It is predicted that ongoing lantana control in the cleared plots will most likely initiate long-term community recovery.

Thesis (MTech (Tourism and Hospitality Management))--Cape Peninsula University of Technology, 2018. / A well-packaged tourism product is the deciding factor in the choice of tourists about which destination to visit. A tourism product can be bundled with many tourism elements such as accommodation, attractions, activities and tours, price, image and climate. The tourism elements that build up a tourism product are the principle factors that contribute to the decision to choose one destination over another destination. Tourists can put a number of tourism products on the table, based on their needs and wants. However, they opt for one tourism product that promises to satisfy their demands. Destinations that offer unique tourism products are the most successful in a competitive industry since tourists will visit such destinations to fulfil their needs. However, even though some destinations like Victoria Falls offer unique tourism products, it is important to understand the nature and trends of tourists visiting this destination and their perceptions of the tourism product. This will assist in planning how to address any areas of concern as well as maintaining areas that are performing well. Limited research exists on tourist perspectives of the Victoria Falls tourism product and hence this is the focus of the current research. It will help in broadening the knowledge of the relevant tourism bodies in Zimbabwe on how tourists view the tourism product, as well as aiding sustainable development and growth of the tourism product. This study followed a quantitative methodology design. The interviewer administered 377 questionnaires on face-to-face basis to tourists on a voluntary participation basis. Systematic sampling was used to collect the data.Key findings indicate that despite the increasing number of females visiting this destination, males still dominate the tourist numbers. The majority of tourists fell within the age bracket of 21-50 years. The findings further show that availability of attractions, price of the tourism product, and accessibility of the destination play a paramount role in influencing tourists to visit the destination. Most tourists’ expectations were met and they would visit again in future and recommend the destination to friends and relatives. The most satisfactory results were noted on the attractions, activities, tours, and tourist accommodation. Despite these positive results, tourists felt that prices of accommodation, activities, tours, as well as dining, was too high. Furthermore, too many police roadblocks and unnecessary fines were noted as being detrimental to the tourism product. The researcher noted all concerns and made recommendations to overcome these negative aspects. The experience of tourists at a destination is strongly associated with an amalgamation of different elements of a tourism product. It is crucial to understand the performance of each tourism element as this contributes significantly to the success of the tourism product. The results of this study will afford the Zimbabwe Tourism Authority and Zimbabwe Parks and Wildlife Management Authority an understanding of the Victoria Falls tourism product from a tourist perspective. These entities will be able to improve the product, make it more attractive to tourists, and hence grow future visitor numbers. In addition, the results of this study create a baseline for future research. Monitoring of tourist perspectives over time and an evaluation and assessment of the tourist demands can be done, which will help in the modification and upgrading of the tourism product to match the demands of the consumers (tourists).
