The tourism sector in Zanzibar Tanzania has emerged strongly in the past 15 years, helping the development of other Industries that support it. As a result, Industries such as telecommunication, IT, transport and hospitality have also emerged recently. It is, however, speculated that organizations in the tourism sector in Zanzibar generally lack the effective performance that is required of them to compete in the contemporary complex and turbulent market environment. This research thus set out to explore and diagnose the organizational effectiveness of the accommodation units of the tourism sector in Zanzibar. The research had specific objectives of diagnosing and finding the gap between the current and the optimal organizational performance in two particular units of accommodation as well as determining the factors affecting organizational performance in these units. The study furthermore set out to recommend implementation of suitable intervention activities to improve organizational performance in the units analyzed. In order to achieve the above objectives the research deployed an action research strategy with the Weisbord’s six box model as a framework to diagnose two five star grade accommodation units in Zanzibar. A qualitative method was used to collect data. Key findings of the research are briefly presented below: - The service output of the accommodation units analyzed was not very consistent and fell short of the expectation of their customers. This showed a gap in terms of the organizations’ performance. - Factors affecting organizational effectiveness were found to be mainly in the Purpose and Rewards functions of the organizations. - The specific areas in the Purpose function that appeared to have substantial problems were: -- Goals of the organization were not clearly stated -- Employees did not understand the purpose of the organization -- Employees were not involved in deciding their work unit goals -- Employees were not in agreement with the goals of their work units. -- Employees did not understand priorities of the organization The specific areas in the Reward function that appeared to have substantial problems were: -- The pay scale and benefits of the organization did not treat employees equitably. -- Employees felt that the salary they received was not commensurate with the jobs they performed. -- Not all tasks to be accomplished were associated with incentives. Following the diagnostics findings above, the research suggested the following intervention activities that could possibly help to address the above mentioned problems: - A Management by Objectives (MBO) process was suggested to redress the problems indicated in the Purpose function. This would help to set clearly agreed goals at all levels of the organizations. Employees and resources would then be directed towards achieving these goals that would enable the organizations to perform more effectively. - Revision of the current reward system was suggested to redress the problems indicated in the Reward function. The reward system should be implemented in a manner that creates a feeling of both internal as well as external (market) equity among employees. Furthermore, rewards should be linked to performance in order to direct behaviour and motivation among employees. The performance based reward system can also help to achieve the MBO process proposed above since rewards will be designated for achievement of individual, departmental and finally organizational objectives, thus increasing organizational effectiveness.

Until recently, scholars of Zanzibar history have not greatly focused on study the history of disease, western medicine and public health in the colonial period. This thesis covers these histories in urban Zanzibar from 1870 to 1963. In addition, it looks at the responses of the urban population to these Western-originated medical and public health facilities during the colonial period. The thesis starts by exploring history of Zanzibar Town during the nineteenth century looking at the expansion of trade and migration of people and how new pathogens were introduced. Local diseases became more serious due to population expansion. I also examine the arrival, introduction and consolidation of Western medical practices. The establishment of hospitals, the training of doctors and nurses and the extension of these facilities to the people are all discussed, as are anti-smallpox, bubonic plague, malaria and sanitation programmes before and after the Second World War. The thesis argues that the colonial government introduced medical institutions in urban Zanzibar with various motives. One of the main reasons was to control disease and ensure the health of the population. The anti-malarial, smallpox and bubonic plague campaigns are an example of how the government tackled these issues. The introduction of preventive measures was also important. The Quarantine Station, the Infectious Diseases Hospital and the Government General Hospitals were established. Other facilities were the Mental Hospitals and Leprosaria. The work of extending medical services was not only done by missionaries and the colonial state but was in great measure through the contribution of Zanzibari medical philanthropists, community, religious and political leaders. Mudiris, Shehas, family members and political parties also played a significant role. In the twentieth century, newspapers owned by individuals and political parties and community associations played a major role too. Zanzibari medical doctors, nurses, orderlies, ayahs, public health staffs were cultural brokers who facilitated the extension of biomedicine and public health measures. By the end of the British colonial rule in Zanzibar in 1963 Western medicine was an important therapeutic option for the people not only in urban Zanzibar but also in both Unguja and Pemba islands. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2009.

This thesis reports on the relationship between an English-only language-ineducation policy and bilingual practices in secondary schools in Zanzibar. The focus is on language use in the classroom against the backdrop of a top-down and English-only language-in-education policy. The main purpose has been to gain an in-depth understanding of the relationship between the stipulations of the policy which was imposed from above and the judicious bilingual practices which are a commonly accepted as the norm in secondary schools in Zanzibar. The study employed a mixed method approach (QUAL+quant) and embraced elements of ethnography. The data for this study was gathered from two secondary schools which were purposively selected on the basis of parameters that were set in this study. Among other things, these include the secondary schools which have both ‘Ordinary level’ and ‘Advance level’, and the schools which teach the same subject using Kiswahili as the language of learning and teaching at one level, and English as the language of learning and teaching at another level. Data were obtained from multiple sources. On the one hand, through ethnography, classroom observations, semi-structured interviews and focus group discussions with teachers and students, and interviews with key actors were conducted. On the other hand, students’ test scripts, and students’ test and examination results (scores) were analysed. Both purposive and random sampling were used to get the participants. Drawing from Ruiz’s (1984) seminal tripartite orientations of language planning (language as right, language as problem, and language as resource) thematic analysis, content analysis, and the Statistical Package for the Social Sciences (SPSS) were used to analyse data. The findings reveal that the use of bilingual (English and Kiswahili) in English medium subjects is a resource rather than a deficit since an overwhelming majority of students and some teachers cannot function positively in the topdown English-only language-in-education policy. Most significantly, teachers use Kiswahili in English medium subjects as a strategy for teaching terminologies, abstract concepts, and unfamiliar topics, as well as for clarification of ideas and for comprehension check. The study further indicates that the examinations and tests of English medium subjects do not assess what is exactly intended to be assessed (subject matter), but instead they assess English language. In addition, empirical evidence shows that language is a factor for students’ achievements in that students performed considerably better when the subjects were assessed in Kiswahili compared to the same subjects assessed in English. The findings further reveal that Kiswahili is suitable to be used as a sole language of learning and teaching in secondary schools of Zanzibar. Based on these findings, the study recommends that the use of Kiswahili in English medium subjects should be officially recognised and students should be given options of the language of assessment as an urgent step. Furthermore, given the urgency of the need for improving students’ performance, it is now high time to introduce Kiswahili medium of instruction secondary schools in Zanzibar which should co-exist with English medium of instruction secondary schools.

This study set out to examine the determinants of participation in non-farm economic activities by farming households in rural Zanzibar, using data from the Agriculture Census of 2003. The study goes beyond the traditional focus of non-farm studies that focus on analysing geographical and socio-economic variables on decisions to participate in non-farm activities and in so doing, fills an information gap and contributes to the understanding of determinants of farm household participation in non-farm activities in rural Zanzibar. The survey from which data were drawn, included surveys of 4755 household heads. Descriptive statistics and logistic regression model were applied to investigate the effect of individual characteristics on the decision to participate in non-farm economic activities. Gender, age, family size and level of education were used as variables to explain individual preference with regard to the decision to undertake non-farm economic activities. The analysis also included farm production factors including farm size, planted area and the main source of household income. The results show that gender, age, household size and income sources outside agriculture are the key factors that influence farming household’s decisions to participate in non-farm activities. Women and young farmers were more likely to participate in non-farm activities. Heads of larger households were also more likely to participate in non-farm activities, and undertake more than one activity in this sector. The type of activity engaged in also seems to have a positive influence on the decision to participate in the non-farm sector, with selling of agricultural products, fishing (including seaweed farming and selling of fish), wage employment and petty trade being more popular and attractive activities. Factors like education, landholding size and area of land planted were less important in influencing participation in non-farm activities. All sampled households participated in non-farm economic activities, with 70 per cent of the participants undertaking more than four activities simultaneously. This points to the importance of non-farm economic activities in providing opportunities to sustain household food security and increase the capacity for households to mitigate shocks. However, a strong relationship was found between participation in non-farm activities and the use of forest resources, as a significant number of activities depend on forest resources. The forest-based non-farm activities reported were: beekeeping, charcoal making and tree logging for poles, timber and firewood. This raises significant concern over the over-utilization of forest resources and subsequent sustainability of the related activities. It is recommended that efforts towards promoting non-farm economic activities should be directed towards developing non-farm activities that are not dependent on forest resources. Interventions enabling increased farm productivity or non-forest activities are important in ensuring food security in Zanzibar. More policy and programme attention should be given to the role of women in non-farm activities. / Thesis (M.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

Parrotfish are a critical component of the herbivore functional group on tropical coral reefs around the world because they mediate competition that occurs between algae and scleractinian corals. Also, because of their feeding technique, which consists of rasping at the substratum with their beak-like teeth, they play an important role in carbonate turnover and the clearing of reef surface area for the settlement of new sessile organisms. Because of these roles, parrotfishes are an important structuring component of coral reef communities. However, individual species can play different roles depending on their physiology, behaviour and ecology. Despite the possible ecological differences that may exist amongst species, specific roles of the fishes remain unclear as the group is most often studied at higher community levels. This thesis applied stable isotope analysis to differing levels of organisation within a parrotfish community to help elucidate their trophic ecology on coral reefs in Zanzibar. Firstly, blood and muscle tissues were compared to identify differences in their isotope signatures. In other organisms, blood turns over faster than muscle tissue so that muscle tissue represents the diet as integrated over a longer period of time. In most species of parrotfish the blood and muscle δ¹³C signatures were not found to be significantly different, but the δ¹⁵N signatures were significantly different between tissues. This indicated that the δ¹³C signature of both tissues would reveal similar dietary information. Conversely, differences in the δ¹⁵N signature indicated that the nitrogen relationship between tissues was more complicated. Secondly, spatial variability in parrotfish, coral, detritus and macroalgae isotope signatures was assessed at different scales. In macroalgae and coral tissues (zooxanthellae and polyp treated separately), the δ¹³C signatures were shown to differ with depth, presumably because of changes in photosynthetic processes related to depth-associated changes in light. While δ¹⁵N signatures were not affected by depth, all organisms showed enrichment at the Nyange reef, the closest reef to the capital of Zanzibar, Stone Town, presumably reflecting the effects of sewage outfall. These results show that processes that impact the δ¹⁵N signatures of primary producers (macroalgae and zooxanthellae) can be traced to higher trophic levels (coral polyps and fish). Lastly, δ¹³C and δ¹⁵N signatures were used to identify ontogenetic dietary changes in multiple species of parrotfish. Four of the species showed stages that varied from the diets that are normally assumed on the basis of their dentition and feeding technique. This indicates that functional roles based on taxonomy or morphology may fail to include possible ontogenetic dietary changes, and may also fail to elucidate the full impact a species could have on coral reef communities. The conclusions from these studies indicate that the species-specific ecological role of parrotfish in coral reef communities can be complex within and between species, and may differ amongst reefs. In light of the natural and anthropogenic pressures that affect coral reef systems, management decisions based on a more complete understanding of the role of these fish in coral reef communities will help decisions that maintain resilience in these fragile systems.

Climate variability and change as well as sea level rise poses significant challenges to livelihoods, water and food security in small island developing states (SIDSs) including the Zanzibar Islands. Thus, without planned strategic adaptation, the future projected changes in climate and sea level will intensify the vulnerability of these sensitive areas. This thesis is based on research conducted in two sites located in the north eastern parts of each island, namely Kiuyu Mbuyuni, Pemba Island and Matemwe, Unguja Island. The research focused firstly on assessing the vulnerability of these two coastal communities to climate variability and change and other stressors. This included investigation of (1) the perceptions of fishers, farmers and seaweed farmers regarding climate stressors and shocks and associated risks and impacts, (2) existing and possible future water and food security issues, and (3) household's access to important livelihood assets. This was followed by an exploration of the coping and adaptive responses of farmers, fishers and seaweed farmers to perceived shocks and stresses and some of the barriers to these responses. Lastly, an analysis of the implications of the findings for achieving sustainable coastal livelihoods and a resilient coastal community was undertaken. The general picture that emerges is that local people along the east coasts of both islands are already vulnerable to a wide range of stressors. Although variability in rainfall is not a new phenomenon in these areas, increasing frequency of dry spells and coastal floods resulting from the influence of El Niño and La Niña events exert enormous pressures on local activities (fishing, farming and seaweed farming) which are the crux of the local economy. The main argument of the study is that the nature and characteristics of these activities are the main source of sensitivity amongst these communities and this creates high levels of vulnerability to climate shocks and trends. This vulnerability is evidenced by the reoccurrence of localised food shortages and the observed food and water insecurity. The study found that food insecurity is a result of unreliable rainfall, drought and seasonality changes. These interacted with other contextual factors such as poor soil, low purchasing power and the lack of livelihood diversification options. In addition to exposure to these almost unavoidable risks from climate variability, the vulnerability of the local communities along the east coasts is also influenced by the low level of capital stocks and limited access to the assets that are important for coping and adaptation. Despite this, some households managed to overcome barriers and adapt in various ways both within the three main livelihood sectors (fishing, farming and seaweed farming) as well as through adopting options outside these sectors resulting in diversification of the livelihood portfolio. However, the study found that most of the strategies opted for by fishers, farmers and seaweed farmers were mainly spontaneous. Few planned adaptation measures supported by state authorities were observed across the sites, with the exception of the provision of motorised boats which were specifically meant to increase physical assets amongst fishers, reduce pressure in the marine conservation areas and prevent overfishing in-shore. Furthermore, numerous strategies that people adopted were discontinued when further barriers were encountered. Interestingly, some of the barriers that prevented households adapting were the same ones that forced households that had responded to abandon their adaptations. To increase resilience amongst east coast communities to current and future predicted changes in climate and sea level, the study argues that traditional livelihood activities (fishing, farming and seaweed farming) need to be better supported, and access to a range of livelihood assets improved. This may be achieved through increased access to local sources of water and facilitation of rainwater harvesting, expanding the livelihood options available to people and increasing climate change awareness, and access to sources of credit.

<p>The distribution and abundance of many coral reef organisms are affected by their predator’s distribution and abundance. Loss of predators may cause a shift in species compositions that will cascade down to other ecological processes on the reef. One example of a shift like this is the growing sea urchin populations inhabiting the coral reefs of East Africa. Areas with high fishing pressure often have large populations of sea urchins. The large populations of sea urchins have a negative impact on the reef ecology both by their grazing and bio-erosion as well as on fish growth and the recovery of fish populations. Previous population genetic studies conducted on<em> Diadema setsosum</em>, using mtDNA and allozymes, found genetic structuring between populations on a large geographical and evolutionary scale. The aim of this study was to examine the genetic population structure of the sea urchin <em>Diadema setosum</em>, at four sites around Zanzibar. We used the amplified fragment length polymorphism (AFLP) technique, a fast and effective method with high resolution. The long term objective is to understand the migration pattern and colonization of <em>D. setosum</em> to facilitate possible management actions. We found a significant genetic structuring of <em>D. setosum</em> hence the populations can not be considered panmictic. The reason behind this structure does not seem to be based on the geography nor size. One possible explanation might be that the structure lies on a larger geographical scale than we have studied, further studies around the Western Indian Ocean may reveal this. Another explanation may be that the structuring is due to differences in spawning time between the different phenotypes and an analysis of gonad maturations may give information about this. To find the reasons behind the observed genetic structure is of great importance for management of the sea urchins and therefore the management of whole reef ecosystems.</p>
