Dissertations / Theses on the topic 'Drought management; Zimbabwe; Africa'

Soil moisture available to crops is among the main constraints on crop production by smallholder farmers in semi-arid Zimbabwe. Other restrictions, such as limited use of fertilisers and herbicides, stem primarily from socio-economic rather than biophysical constraints. To improve smallholder farming, it is essential to promote soil and water conservation practices (SWC) that consider farmers' management constraints, such as limited availability of labour and Draught Animal Power (DAP).

The recent adoption of the Trade Facilitation Agreement by WTO members in 2014 renewed the global impetus to ease the movement of goods. Developing countries in Sub Saharan Africa have joined the global community in this regard. It has been noted that although tariffs in developing countries have been lowered, numerous non-tariff barriers and non-tariff measures are stifling trade. Cumbersome border processes have added avoidable costs to trade. In this study, we examine the challenges being faced in Zimbabwe in the transboundary movement of goods. The study makes use the World Bank database on Trading Across Border, Logistics Performance Indicators, and the Ad Valorem Equivalent by the World Bank's Economic and Social Community for Asia and Pacific. The data is compared with South Africa, Zambia, OECD High Income Countries, and East Asia. The findings show that, it is a huge challenge to move goods in Zimbabwe. In other words, doing business with Zimbabwe is not for the faint at heart. These challenges emanate from exorbitant administrative fees, high document requirements, and time delay constraints. These costly non-tariff barriers present a costly murky trade protectionism. The entire logistics chain and infrastructure system need to be revamped to improve reliability and minimise trade costs. When compared to ad valorem equivalent, Zimbabwe trade costs with South Africa and Zambia in agriculture are in excess of 100%, while those for the manufactured goods average 65%. The high trade costs in agriculture are high mainly due to excess requirements in terms of processes and procedures to move goods across borders. Combining trade costs data with specific knowledge on trade facilitation, logistics and trade policy will provide a comprehensive diagnosis that will help to prioritize reform packages that carry maximum impact. In light of these findings, the research recommends to customs officials and government policy makers, areas to address in the entire trade facilitation process that will bring huge impact in terms of removal of border inefficiencies, minimising of trade costs, and improvement of the logistics chain. These recommendations range from the establishment of single window system, integrated border management, and one stop border posts as part of the entire process under trade facilitation.

The climate of southern Africa varies greatly spatially and temporally. Tyson‟s (1987) examination of long-term rainfall records has shown an 18-year cyclical pattern of wet spells alternating with dry spells. Recurrent droughts are thus a feature of southern Africa‟s climate. Although climate change resulting from global warming could intensify future droughts, current predictions of regional climate change are unreliable. This study evaluates the nature, adequacy and effectiveness of Zimbabwe‟s drought policy in reducing the vulnerability of rural communities to the impact of drought. The objectives of the study are to explore the different meanings of the concept of drought; to explain the relevant concepts and frameworks of the hazard assessment and management discipline; to describe the current status of disaster management in general and drought in particular; to identify the mechanisms used by small-scale farmers in Sontala ward for coping with drought; and to evaluate the adequacy and effectiveness of Zimbabwe‟s drought policy in reducing the vulnerability of rural communities to drought impacts. A qualitative approach was used which involved analysis of government documents and academic literature. Semi-structured interviews were conducted with government officials at provincial level and small-scale farmers at ward level in Matabeleland South province. The data collection exercise was, however, constrained by the current political instability in the country. The study established that the Civil Protection Act No 10:06 of 1989, complemented by relevant sections of other laws, provides a legal framework for disaster management. The Ministry of Local Government, Public Works and Urban Development has a coordinating role. Coordinating committees at national, provincial and district level formulate disasterresponse plans to be activated when a disaster occurs. The Civil Protection System uses existing government, private and non-governmental organizations whose regular activities contain elements of disaster risk prevention and community development. The enactment of the Emergency Preparedness and Disaster Management Act will remove some of the shortcomings of the Civil Protection System.

The number of orphaned children in many parts of Africa is increasing as their parents die from human immunodeficiency virus (HIV) or acquired immune deficiency syndrome (AIDS). The research problem addressed in this qualitative study was lack of understanding by others about how the managers of orphanages in 2 African countries -- South Africa and Zimbabwe - were responding to the emotional and social needs of these orphans. The purpose of this study was to develop an orphanage management theory or model that could replicate the African kinship environment in the orphanages under study. Nurturing leadership theory provided the conceptual backdrop for this study. The research design was informed by Glaser's grounded theory (GT) approach. Data collection involved a qualitative survey of 20 administrators in 2 orphanages in South Africa and Zimbabwe. Open coding, memoing, and selective coding of this data yielded a nurturing model for orphanage management in the cultural context of the African kinship system. From the viewpoint of social change, this research suggests development of a family-oriented orphanage management system to help the orphans live healthy and productive lives without the stigma of HIV and AIDS.

Pastoralists in Africa have developed complex mechanisms by which they can alleviate the threat of drought. They practice mobility as one of the strategies to avoid the worst effects of natural stress and disperse grazing pressure. In the past in South Africa, the indigenous Nama people occupied large areas of land and moved around extensively to exploit seasonal differences in the availability of forage and water. With the settlement of the Europeans in the Cape the indigenous people lost most of their land to the colonists. The Nama people were, therefore, restricted to smaller rangelands and their patterns of rangeland use had to adapt to the spatial constraints. Descendants now herd livestock from semi-permanent stockposts that are scattered throughout the commons. Herders use a range of practices to manage their livestock. The aims of this study was to assess the agro-ecological knowledge of livestock keepers
assess the condition of the rangeland during drought
determine the herding strategies of herders during drought.

The purpose of this study was to determine the extent to which certain selected factors serve as drivers of innovation in small accommodation businesses (SABs) in two developing economies in Southern Africa namely South Africa and Zimbabwe with the ultimate aim of assisting policy makers and support agencies in formulating innovation oriented strategies for the sector. Two samples were randomly selected from SABs in Zimbabwe and South Africa- two neighbouring Southern African countries. Parametric tests which include t-tests and one-way ANOVAs as well as Bonferonni tests as post-hoc measures were used to test whether SAB propensity to engage in different dimensions of innovation differs by gender; firm size, owner-managers’ years of experience and level of education respectively. Pearson Product Moment Correlations were employed to assess the relationships between market orientation, learning orientation and innovation while Chi-square tests were performed to establish the inter-relationships between independent demographic variables, namely age, gender, education and work experience. In order to investigate whether there are any significant interaction effects between the age of the respondents and their experience in the accommodation sector on each of the five innovation measures, a series of two-way ANOVA tests were performed. Lastly, regression analysis was used to determine the relative efficacy of market orientation (MO), learning orientation (LO) and country in predicting innovation in a business. The results demonstrate that unlike firm size, gender and level of education, which have no association with innovation, there is a strong association between market orientation, learning orientation, owner/managers age and experience and innovation in the two countries. This positive association implies that SABs that are committed to, listen attentively to and learn proactively about their customers’ needs and expectations are better inclined to engage in all the different dimensions of innovation (product/service, process, marketing and organisational) than their counterparts who do not engage in these activities. Among other drivers of innovation, market orientation emerged as the main predictor implying that SABs that invest more in marketing tend to be better innovators than those that invest in learning irrespective of their country of operation. The study also revealed that younger owner/managers of SABs tend to be more innovative than their older, experienced counterparts. The study makes an important contribution to literature on the drivers of innovation in small accommodation businesses in developing economies by dispelling firm size, gender and level of education which were regarded as drivers of innovation across industries previously. Practice and policy wise, the study led to the development of a conceptual framework for investigating how best to drive innovation in local SABs in order to make them more competitive, survive and grow in the face of competition from large accommodation businesses that often happen to be multinational.

The number of people around the world who are affected by humanitarian crises has almost doubled in the past decade. For instance, in 2016, Southern Africa experienced the worst drought in 35 years, due to the weather phenomenon El Niño, and all aspects of society were affected. The aim of this thesis is to identify and analyse different types of challenges humanitarian relief programmes face in their disaster management in two different contexts: a conflict and a non-conflict context. The thesis combines both disaster management and peace and conflict studies. Interviews have been conducted in Zimbabwe (non-conflict) and Mozambique (conflict) with INGOs, UN organisations and donors that were involved in the humanitarian relief programmes in the countries during the El Niño induced drought in 2016. The programmes experienced various challenges, and additional challenges have been found in the humanitarian relief programmes in Mozambique due to the conflict. This thesis contributes to the existing theory with one piece of the puzzle: combining the theories on disaster management and peace and conflict studies and showing that neighbouring countries to those in conflict are likely to get spillover challenges from the country in conflict, primarily due to issues with refugees.

Knowledge is now regarded as the most important resource surpassing other resources like land and capital. It is a foregone conclusion that knowledge flows out of organizations through various ways such as resignations, retirement and death yet, it does not seem as if organizations are employing strategies to retain such a vital component of production and service delivery. This study investigated the knowledge retention strategies in three Southern Africa Development Community (SADC) public broadcasting organizations of the South African Broadcasting Corporation in South African (SABC), the Department of Broadcasting Services (DBS) in Botswana and the Zimbabwe Broadcasting Corporation (ZBC) in Zimbabwe. The aim of this study was to establish how knowledge is captured and retained at such organizations. The objectives of the study were; to find out the types of strategies the three broadcasting organizations employ to capture and retain knowledge; establish how the three broadcasting organizational cultures enable knowledge acquisition, transfer, sharing and retention; establish the role of ICTs as tools and enablers of knowledge retention, creation, transfer and sharing in the three broadcasting organizations; and to propose recommendations on the best strategies for retention of knowledge in the three public broadcasting organizations as well as suggest areas for further and future research. v The study used the survey method and employed the triangulation design for data gathering. Data were collected from three SADC public broadcasting organizations. The population sample comprised 240 professional staff including 38 managers from different sections of the broadcasting organizations. The researcher collected data by administering a questionnaire to staff, interviews with managers and observations. Documentary analysis was also conducted in order to supplement data and fill in gaps. The researcher was mainly interested in gathering data that would give a comprehensive picture about knowledge retention methods in broadcasting organizations. There were four main findings. First, knowledge management as a relatively new concept and practice has not yet been properly embraced in the public broadcasting organization system in order to capture and retain knowledge that is acquired and generated in the organizations. There are no measures put in place in the organizations to retain the knowledge to ensure that once those who hold vital tacit knowledge are gone, the knowledge may still be available and accessible. Second, the study established that the respective organizational cultures impede on organizational knowledge retention. The study established that there was no culture of knowledge sharing. It also emerged that employees were not free to share their knowledge because of government regulations, prevailing political contexts, mistrust and general lack of incentive to share knowledge. Third, the study established that the organizations have no strategies or systems in place to capture the experts‟ knowledge or the knowledge of experienced staff and vi those approaching retiring age. The Human Resources Departments hold exit interviews that cover issues purely to do with why the person is leaving the organization instead of recording the work experiences and expertise of the departing employees. Fourth, the study revealed that the public broadcasting organizations still lag behind in collaborative and communicative technologies that facilitate knowledge transfer and sharing of tacit knowledge but retention of knowledge generally. The study also found that, some of the organizations studied did not have internet connectivity and websites were not yet functional, which hampered acquisition and sharing of knowledge for retention purposes. The importance of this study is that it has made a contribution and provided literature on knowledge retention strategies for public broadcasting corporations as part of knowledge management practice. On the basis of these findings the study recommended the following: appointment of knowledge management officers, establishment of Communities of Practice, encouraging knowledge sharing between employees, introduction of joint programmes with other broadcasting organizations by managers and their supervision of mentoring programmes; organizations to facilitate acquisition of information and communication technologies that enable knowledge management

This study is a contribution to the literature on South Africa's foreign policy since 2000-2004. It provides a theoretical framework within which South Africa's foreign policy should be understood. It attempts to explain the contradictions that have been apparent in South Africa's foreign policy by looking at the constraints inherent in South Africa's position as an emerging middle power. It argues that South Africa's pluralist inclinations are constrained by Africa's evolving multilateral forums and that South Africa's preference for such undermines the realization and achievement of her foreign policy principles and goals. It also argues that as a realist middle power, South Africa is constrained the ambivalence shown by the region towards her exercising leadership in the region. This is due to South Africa's history of destruction in Southern Africa in the 1980's. South Africa's quiet diplomacy towards Zimbabwe provides the focal point for the study. The study argues that it is not the case that South Africa is not concerned with human rights abuses in Zimbabwe. Instead, this concern has been expressed in ways that do not tarnish South Africa's own image in Africa. This has been done by engaging Zimbabweans through multilateral forums. This study concludes that this strategy failed to bring about resolution to the Zimbabwean crisis.

Thesis (MPhil)--Stellenbosch University, 2012.
ENGLISH ABSTRACT: The study represents an analysis of the role of civil society organisations/non‐governmental organisations (CSOs/NGOs) in building human capabilities through knowledge construction. It assesses the effectiveness of community publishing in building human capabilities under challenges they face in the environment they are operating in. The complex environment CSOs/NGOs are operating in is dealt with. It will be demonstrated that CSOs/NGOs give marginalised communities, especially women, children and the disabled, a platform where they can organise themselves and give them an opportunity to influence policy and development of their community. Community development has many interpretations. This study focuses on communities as central agents responsible for their own development. When communities participate in their own development, they are engaging in an educational process which is both formal and informal in nature. The education process helps them to understand their situations better. This type of education called ‘popular education’, is based on the belief that people involved in the process have important knowledge that they have acquired from their experiences in life and the education they receive mainly consists of dialogue between different knowledge sets that they possess. In the process, when people participate actively in the development of their communities, a sense of ownership is developed. For the purpose of designing the study, observation of the direct involvement of staff from local government, Africa Community Publishing Development Trust and partner organisations as well as working with communities from Shamva, Umzingwane and Buhera provided the basis. It is noted that party politics affects the development of a CSO/NGO sector that is capable of building human capabilities. It is, therefore, clear that government should create an enabling environment that is free from violence and rule of law should be respected as this helps CSOs/ NGOs to implement capability building programmes conducive for all communities to participate in the development of their areas.
AFRIKAANSE OPSOMMING: Die studie ontleed die rol van burgerlike organisasies/nie‐regeringsorganisasies (BOs/NRO's) in die bou van menslike vermoëns deur middel van kennis konstruksie. Die studie beoordeel die effektiwiteit van die gemeenskap uitgewery in die bou van die menslike vermoëns en die uitdagings wat hulle in die gesig staar in die omgewing waar hulle hul bevind. Die komplekse omgewing waarin BOs / NRO’s hul bevind word inmiddels behandel. BOs/NRO's gee gemarginaliseerde gemeenskappe veral vroue, kinders en gestremdes 'n platform waar hulle hul self kan organiseer en gee hulle ' n geleentheid om beleid te beïnvloed en hul gemeenskap te ontwikkel. Ontwikkeling van die gemeenskap het baie interpretasies. Die studie fokus op die gemeenskappe as sentrale agente wat verantwoordelik is vir hul eie ontwikkeling. Wanneer gemeenskappe betrokke is in hul eie ontwikkelings proses, neem hulled deel aan ’ n opvoedkundige proses wat van nature beide formeel en informeel is. Die opvoedkundige proses help hulle om hul situasies beter te verstaan. Hierdie tipe van Onderwys genaamd "gewilde onderwys", is gebaseer op die oortuiging dat mense wat betrokke is in ‘n proses belangrike kennis besit as gevolg van persoonlike lewenservaringe, die opvoeding wat hulle ontvang bestaan hoofsaaklik uit dialoog tussen die verskillende kennis stel dat hulle besit. Wanneer mense aktief deelneem in die ontwikkeling van hul gemeenskappe, word 'n gevoel van eienaarskap ontwikkel. In terme van die ontwikkeling van die studie het die direkte betrokkenheid van die personeel van plaaslike regering, ACPDT en vennoot organisasies asook die werk met die gemeenskappe van Shamva, Umzingwane en Buhera die basis gevorm van die studie. Politieke partye beinvloed die ontwikkeling van die BO/NRO‐sektor en dit stel hulle in staat om menslike vermoëns op te bou. Die regering moet 'n instaatstellende omgewing skep wat vry is van geweld en waar die oppergesag van die reg gerespekteer word. Dit sal BO’s/NRO's help om vermoëns bouende programme te implementeer wat gemeenskappe die geleentheid sal gee om deel te hê aan die ontwikkeling van hul gemeenskap.

By presenting case studies from the village of Mahenye in Zimbabwe and the five villages of the Okavango Community Trust in Botswana, the study looks beyond the objectives, discourse and contests of policy and undertakes an investigation of what actions rural people are undertaking inside the institutions established by policy makers, and of governance outcomes at the local level. These case studies reveal that unfettered devolution can lead to elite capture and the perpetuation of poverty; that rural communities themselves have agency and the ability to exercise it; and that there is limited and shrinking political space in both countries which is reducing opportunities for rural communities to engage with political processes. The Botswana case studies demonstrates that an imported and imposed devolutionary initiative which lacks links to higher levels of governance can reduce political space at local levels. The Zimbabwe case study demonstrates that political space may be more effectively created through decentralisation. The lesson drawn from these case studies is that institutional arrangements and roles should be determined by context specific issues and circumstances and move beyond the structural determinism that has characterized much of the CBNRM debate to date. The study concludes with policy recommendations. These include the need for recognition of the synergy between CBNRM and democratisation as mutually reinforcing processes and the need to be context-specific.

Tropical woodlands play a key role in the livelihoods of rural communities in southern Africa, but exist in contexts of constant ecological and socioeconomic change. With research into tropical woodlands neglected compared to tropical forests, it is important to improve understanding of the consequences of tropical woodland change for rural wellbeing. The aim of this thesis is to examine the dynamic interactions between woodland change and rural livelihoods through an interdisciplinary case study of a miombo woodland landscape on and around Wedza Mountain, Zimbabwe. The thesis is organised into three parts addressing: (1) the patterns of land use intensity and provisioning ecosystem service availability around Wedza Mountain; (2) the importance of environmental resources in rural income portfolios and hazard coping strategies; and (3) the adequacy of ecosystem service literature in representing the environmental values of rural African communities. The first part of this thesis explores patterns of land use and woodland structure on the woodland cover gradient around Wedza Mountain. In Chapter 2 I characterise land use intensity in the six study villages using a new method of calculating human appropriation of net primary productivity (HANPP) at the village scale. Use of this approach indicates that previous studies have underestimated land use intensity in African small-scale farming areas, with village-scale HANPP estimates in Wedza ranging from 48% to 113% of total potential annual NPP as compared to 18 to 38% in published studies. In Chapter 3 I combine woodland survey data with a quantitative ethnobotanical assessment of the use values of woody species and demonstrate that per-household availability of provisioning ecosystem services declines with declining relative tree cover. These findings also suggest that more deforested villages have reduced diversity of ethnospecies underlying service provision, with ramifications for service resilience and livelihood option values in response to future change. The focus of the second part of the thesis is on the role of woodland resources in rural livelihoods. In Chapter 4 I quantify the contribution of environmental income to the total income portfolios of 91 households and show that lower village woodland cover is not associated with reduced livelihood diversity, in part because a large proportion of environmental income is derived from degraded woodland or non-woodland environments. In Chapter 5 I assess the importance of environmental resources for coping with hazard exposures, drawing on recall of past exposure responses and a survey exercise weighting the elements of coping strategy portfolios in response to varying shock scenarios. Synthesis of these data sets indicates that environmental resources represent an important safety net in coping with interacting covariate and idiosyncratic hazard exposures. The third part of the thesis consists of critical reflection, firstly on the adequacy of current ecosystem services research in southern Africa landscapes and secondly on this specific research project. In Chapter 6 I identify the value discourses which are most dominant across 356 peer-reviewed papers adopting an ecosystem services approach to miombo landscape research, and contrast these with the environmental values of study communities in Wedza District. Through this I show that the current ecosystem service literature is failing to represent rural African social and spiritual imaginaries of landscapes, with potentially serious consequences for the efficacy and equity of landscape management interventions. In Chapter 7 I examine some of the methodological and ethical challenges encountered during this research project through a discussion of the relationships between researcher, research assistant and respondents in an interdisciplinary field research context. Finally, in Chapter 8 I synthesise the key messages from the thesis, and conclude by discussing the implications of our findings for understanding of how future change will impact the resilience and vulnerability of savanna woodland socioecological systems.

This study is a comparative analysis of the development of the IWRM induced public policies/legislation and services relating to potable water supply and their implementation in selected cases in Zimbabwe and South Africa. It looks at the diverse patterns of municipal governance, access to potable water, different intervention mechanisms made by the local authorities and the consequences of these interventions. The study hypothesises that the adoption of the IWRM policy framework in Harare, Masvingo, Tshwane and Vhembe was not followed by comparable implementation of the policy framework. It argues that lack of ownership, lack of political and public administrative will, and low prioritisation of potable water supply translated into a lack of policy implementation and enforcement, and a lack of adequate institutional facilities for dealing with potable water issues. Furthermore it hypothesises that the level of economic development and the status of technological/scientific knowledge within a community determine the adoption of the IWRM paradigm, its implementation, effectiveness and the efficiency of existing water frameworks and institutions. The objectives of the study were to investigate the extent to which the policy, institutional, legislative and legal frameworks helped in the implementation of the IWRM paradigm in each of four case study areas of Harare, Masvingo, Tshwane and Vhembe; to identify and explain the common and differing perspectives of stakeholders regarding the IWRM paradigm and its implementation in the governance of potable water supply in the four selected locations; to give a clear outline of the challenges faced by each of the four cases in the implementation of the IWRM paradigm and the governance of potable water supply; and to draw comparative lessons from the experiences of the four cases in their attempts to implement the IWRM framework. Research methods involved both a theoretical review and an empirical study based on case studies, making use of comparative, qualitative, historical and exploratory approaches. The empirical research design was hybrid, although dominated by the descriptive survey approach. The design matched well with the target population and sample that were scattered throughout all four case study areas. Questionnaires, interviews, documentary evidence and participant observation were used in the collection of data for this study. The empirical study was undertaken in three stages. The first was a preliminary study of the four areas and their water sources. This was followed by a pilot study with ten members from the city of Masvingo, and finally, a full scale investigation was made in all four study areas. A total of 521 people were sampled for the study. Questionnaires were distributed through municipal offices, Zimbabwe Open University (ZOU) offices and local schools. Interviews were conducted with the municipal and council executives, water directors and their assistants. Informal discussions were also held with all direct research assistants. Data was then collated and analysed for presentation in narrative descriptions, tables, graphs, and actual frequencies and percentage responses. The study established that while the framework for a perfect water management system exists in Zimbabwe and South Africa, the situation on the ground does not reflect this common belief. The reform process has not progressed as expected owing to a combination of factors ranging from conflicting policies and weak institutional linkages, to insufficient funding. The effectiveness of the new system has been found wanting as far as implementation is concerned. It has been established that IWRM in southern Africa has a very strong base in the form of the internal push factors and international pull factors, but also faces an uphill task in terms of aligning local and international challenges thereby co-opting the much needed grassroots participation for human capacitation and socio-economic development as guided by the multi-faceted systems framework. All the studied municipalities were found lacking in terms of advocacy or enlightening residents and other stakeholders of the new IWRM framework adopted by the municipalities. Despite the infrastructural and technological sophistication and advancement, in South Africa, this study established that most stakeholders were still unaware of the new developments. Stakeholders, especially at the grassroots have been largely side-lined in the formulation and adoption of potable water supply policies. Due to pipe bursts and water interruptions, access to tap water is by no means always assured. During water cuts, residents depended on risky and potentially polluted sources even in urban centres. Due to agricultural and mining activities, the proximity of cemeteries, poor sanitation and toilet facilities in the peri-urban and nearby shanty communities, and also the dolomitic character of the soil in some of the study areas, there is a high probability that these substitute sources are polluted. The study recommends an integrated systems approach to the management of potable water supply, full involvement of all stakeholders in the management process, intensive and extensive public campaigns, training, lobbying and advocacy. It is also suggested that potable water supply infrastructure be improved through the use of the business community and other stakeholders, who should be mobilised through the use of attractive incentives. Among other recommendations are the due enforcement of water laws, venturing into entrepreneurial activities, interval reviews and check-ups, and walking the talk. The study also recommends a more detailed and deeper participatory study in collaboration with major cities and rural communities in other countries in the Southern Africa Development Community (SADC) region, as well as regional comparative studies, for example SADC versus Economic Community Organisation of West African States (ECOWAS).

Water is recognised as a key driver for social and economic development in the Zambezi basin. The basin is riparian to eight southern African countries and the transboundary nature of the basin’s water resources can be viewed as an agent of cooperation between the basin countries. It is possible, however, that the same water resource can lead to conflicts between water users. The southern African Water Vision for ‘equitable and sustainable utilisation of water for social, environmental justice and economic benefits for the present and future generations’ calls for an integrated and efficient management of water resources within the basin. Ensuring water and food security in the Zambezi basin is, however, faced with challenges due to high variability in climate and the available water resources. Water resources are under continuous threat from pollution, increased population growth, development and urbanisation as well as global climate change. These factors increase the demand for freshwater resources and have resulted in water being one of the major driving forces for development. The basin is also vulnerable due to lack of adequate financial resources and appropriate water resources infrastructure to enable viable, equitable and sustainable distribution of the water resources. This is in addition to the fact that the basin’s economic mainstay and social well-being are largely dependent on rainfed agriculture. There is also competition among the different water users and this has the potential to generate conflicts, which further hinder the development of water resources in the basin. This thesis has focused on the Zambezi River basin emphasising climate variability and climate change. It is now considered common knowledge that the global climate is changing and that many of the impacts will be felt through water resources. If these predictions are correct then the Zambezi basin is most likely to suffer under such impacts since its economic mainstay is largely determined by the availability of rainfall. It is the belief of this study that in order to ascertain the impacts of climate change, there should be a basis against which this change is evaluated. If we do not know the historical patterns of variability it may be difficult to predict changes in the future climate and in the hydrological resources and it will certainly be difficult to develop appropriate management strategies. Reliable quantitative estimates of water availability are a prerequisite for successful water resource plans. However, such initiatives have been hindered by paucity in data especially in a basin where gauging networks are inadequate and some of them have deteriorated. This is further compounded by shortages in resources, both human and financial, to ensure adequate monitoring. To address the data problems, this study largely relied on global data sets and the CRU TS2.1 rainfall grids were used for a large part of this study. The study starts by assessing the historical variability of rainfall and streamflow in the Zambezi basin and the results are used to inform the prediction of change in the future. Various methods of assessing historical trends were employed and regional drought indices were generated and evaluated against the historical rainfall trends. The study clearly demonstrates that the basin has a high degree of temporal and spatial variability in rainfall and streamflow at inter-annual and multi-decadal scales. The Standardised Precipitation Index, a rainfall based drought index, is used to assess historical drought events in the basin and it is shown that most of the droughts that have occurred were influenced by climatic and hydrological variability. It is concluded, through the evaluation of agricultural maize yields, that the basin’s food security is mostly constrained by the availability of rainfall. Comparing the viability of using a rainfall based index to a soil moisture based index as an agricultural drought indicator, this study concluded that a soil moisture based index is a better indicator since all of the water balance components are considered in the generation of the index. This index presents the actual amount of water available for the plant unlike purely rainfall based indices, that do not account for other components of the water budget that cause water losses. A number of challenges were, however, faced in assessing the variability and historical drought conditions, mainly due to the fact that most parts of the Zambezi basin are ungauged and available data are sparse, short and not continuous (with missing gaps). Hydrological modelling is frequently used to bridge the data gap and to facilitate the quantification of a basin’s hydrology for both gauged and ungauged catchments. The trend has been to use various methods of regionalisation to transfer information from gauged basins, or from basins with adequate physical basin data, to ungauged basins. All this is done to ensure that water resources are accounted for and that the future can be well planned. A number of approaches leading to the evaluation of the basin’s hydrological response to future climate change scenarios are taken. The Pitman rainfall-runoff model has enjoyed wide use as a water resources estimation tool in southern Africa. The model has been calibrated for the Zambezi basin but it should be acknowledged that any hydrological modelling process is characterised by many uncertainties arising from limitations in input data and inherent model structural uncertainty. The calibration process is thus carried out in a manner that embraces some of the uncertainties. Initial ranges of parameter values (maximum and minimum) that incorporate the possible parameter uncertainties are assigned in relation to physical basin properties. These parameter sets are used as input to the uncertainty version of the model to generate behavioural parameter space which is then further modified through manual calibration. The use of parameter ranges initially guided by the basin physical properties generates streamflows that adequately represent the historically observed amounts. This study concludes that the uncertainty framework and the Pitman model perform quite well in the Zambezi basin. Based on assumptions of an intensifying hydrological cycle, climate changes are frequently expected to result in negative impacts on water resources. However, it is important that basin scale assessments are undertaken so that appropriate future management strategies can be developed. To assess the likely changes in the Zambezi basin, the calibrated Pitman model was forced with downscaled and bias corrected GCM data. Three GCMs were used for this study, namely; ECHAM, GFDL and IPSL. The general observation made in this study is that the near future (2046-2065) conditions of the Zambezi basin are expected to remain within the ranges of historically observed variability. The differences between the predictions for the three GCMs are an indication of the uncertainties in the future and it has not been possible to make any firm conclusions about directions of change. It is therefore recommended that future water resources management strategies account for historical patterns of variability, but also for increased uncertainty. Any management strategies that are able to satisfactorily deal with the large variability that is evident from the historical data should be robust enough to account for the near future patterns of water availability predicted by this study. However, the uncertainties in these predictions suggest that improved monitoring systems are required to provide additional data against which future model outputs can be assessed.

This study explores representation and use of indigenous heritage constructs with a view to identifying implications thereof for the quality and relevance of heritage education practices in post colonial southern Africa. Framed within a critical hermeneutic research paradigm under-laboured by critical realist ontology, the study was conducted using a multiple case study research design. The data collection protocol was three-phased, starting with a process of contextual profiling, within which insights were gained into discourses shaping the constitution and orientation of heritage education practices at the Albany Museum in South Africa, the Great Zimbabwe Monument in Zimbabwe and the Supa Ngwao Museum in Botswana. The second phase of data collection entailed modelling workshops in which educators engaged in discussion around the status of heritage education in post apartheid South Africa. This highlighted, through modelled lessons, some of the tensions, challenges and implications for working with notions of social transformation and inclusivity in heritage education. The third phase of data collection involved in-depth interviews. Twelve purposively selected research participants were interviewed between 2010 and 2011. Data generated across the study was processed and subjected to different levels of critical discourse analysis. Besides noting how heritage education in post colonial southern Africa is poorly framed and under-researched, this study revealed that current forms of representing indigenous heritage constructs are influenced more by socio-political discourses than the need to protect and conserve local heritage resources. The study also noted that the observed heritage education practices are oriented more towards addressing issues related to marginalisation and alienation of indigenous cultures and practices, than enhancing learners’ agency to manage and utilise local heritage resources in a more sustainable ways. Based on these findings the study recommends re-positioning heritage education within the framework of Education for Sustainable Development (ESD). ESD acknowledges both issues of social justice and the dialectical interplay between nature and culture; as such, it may allow for representation and use of indigenous heritage constructs in ways that expand current political orientations to include sustainability as an additional objective of heritage education. Given that little research focusing on heritage education has been undertaken within southern Africa, the findings of this study provide a basis upon which future research may emerge.

Dams and reservoirs with multiple purposes require effective management to fully realize their purposes and maximize efficiency. For instance, a reservoir intended mainly for the purposes of flood control and hydropower generation may result in a system with primary objectives that conflict with each other. This is because higher hydraulic heads are required to achieve the hydropower generation objective while relatively lower reservoir levels are required to fulfill flood control objectives. Protracted imbalances between these two could increase the susceptibility of the system to risks of water shortage or flood, depending on inflow volumes and operational policy effectiveness. The magnitudes of these risks can become even more pronounced when upstream use of the river is unregulated and uncoordinated so that upstream consumptions and releases are arbitrary. As a result, safe operational practices and risk management alternatives must be structured after an improved understanding of historical and anticipated inflows, actual and speculative upstream uses, and the overall hydrology of catchments upstream of the reservoir. One of such systems with an almost yearly occurrence of floods and shortages due to both natural and anthropogenic factors is the dual reservoir system of Kainji and Jebba in Nigeria. To analyze and manage these risks, a methodology that combines a stochastic and deterministic approach was employed. Using methods outlined by Box and Jenkins (1976), autoregressive integrated moving average (ARIMA) models were developed for forecasting Niger river inflows at Kainji reservoir based on twenty-seven-year-long historical inflow data (1970-1996). These were then validated using seven-year inflow records (1997-2003). The model with the best correlation was a seasonal multiplicative ARIMA (2,1,1)x(2,1,2)12 model. Supplementary validation of this model was done with discharge rating curves developed for the inlet of the reservoir using in situ inflows and satellite altimetry data. By comparing net inflow volumes with storage deficit, flood and shortage risk factors at the reservoir were determined based on (a) actual inflows, (b) forecasted inflows (up to 2015), and (c) simulated scenarios depicting undefined competitive upstream consumption. Calculated high-risk years matched actual flood years again suggesting the reliability of the model. Monte Carlo simulations were then used to prescribe safe outflows and storage allocations in order to reduce futuristic risk factors. The theoretical safety levels achieved indicated risk factors below threshold values and showed that this methodology is a powerful tool for estimating and managing flood and shortage risks in reservoirs with undefined competitive upstream consumption.

Introduction

Depuis une quinzaine d'années en Afrique, cercles de qualité, audits cliniques, cycles de résolution de problèmes et autres 'projets qualité' ont été mis en oeuvre dans les services publics de santé pour améliorer la qualité des soins. Ces projets ont souvent mis l'accent sur des approches participatives, la résolution locale de problèmes et le changement, bousculant les pratiques managériales traditionnelles. A court terme, les évaluations montrent l'amélioration des résultats de programmes ou d'activités. Mais la pérennité de la dynamique reste largement à prouver. Le véritable aboutissement d'un programme d'assurance qualité devrait être apprécié à l'aune de sa capacité à mettre la préoccupation pour la qualité au cœur du management et du fonctionnement du système, et ce de façon continue. C'est en effet la vision moderne de l'assurance qualité déclinée dans les approches du management de la qualité totale, de l'amélioration continue de la qualité ou de l'organisation apprenante.

Méthode

La définition, la mesure et le management de la qualité en santé se révèlent être beaucoup plus qu'une simple procédure technique: c'est un processus social dans un système complexe dont l'étude requiert une approche méthodologique appropriée (Chapitre 1). Notre objectif est d'explorer dans quelle mesure les projets qualité ont permis aux systèmes de santé d'adopter les principes du management de la qualité.

Nous proposons de conduire une 'évaluation réaliste' de projets qualité en Afrique (Chapitre 2). Conceptualisée par Pawson et Tilley (1997) dans le domaine des sciences sociales, l'évaluation réaliste ('realistic evaluation') est une approche méthodologique de la famille des theory based evaluations. Au-delà du constat d'un effet produit par une intervention, l'évaluation réaliste cherche à comprendre ce qui marche, pour qui, dans quelles circonstances et comment. Alors que les résultats issus de la 'grounded theory', de la recherche action et d'autres méthodes de recherche sur les systèmes de santé restent très liés à un contexte, l'évaluation réaliste génère des théories intermédiaires ('middle range theories') qui permettent d'étendre la validité des interprétations au-delà d'un contexte particulier. Construite autour d'études de cas menées dans des contextes multiples et variés, l'évaluation réaliste met en effet l'accent sur l'interaction entre le contexte et la logique d'une intervention.

Résultats

Afin de construire une théorie initiale, nous comparons les systèmes de santé Européens et Africains à l'aide des configurations organisationnelles de Mintzberg (chapitre 3). Nous mettons ainsi en évidence le rôle joué par la nature bureaucratique ou professionnelle de la configuration des organisations de santé dans les résistances à l'introduction des principes du management de la qualité.

Nous menons ensuite une série d'études de cas au Niger, en Guinée, au Maroc et au Zimbabwe pour étudier cette interaction. Dans une première série comparative de trois études de cas (Chapitre 4), nous mettons en évidence la tension qui existe entre la logique de commande et de contrôle des organisations bureaucratiques et la logique de l'assurance qualité valorisant la prise d'initiative de changement par des équipes non hiérarchisées. Nous explorons ensuite cette tension dans trois études de cas distinctes au Zimbabwe et au Maroc. Laissées à la merci des contraintes bureaucratiques, les initiatives locales pour améliorer la qualité apparaissent dépendantes de la capacité des acteurs à développer des stratégies de contournement (Chapitre 6). Faute de quoi elles doivent réduire fortement leurs ambitions à moins qu'elles ne bénéficient d'un soutien émanant d'une institution située hors de la ligne hiérarchique mais reconnue légitime (Chapitre 5). Les systèmes publics de santé de ces pays, conçus comme des organisations bureaucratiques structurées autour de relations hiérarchiques de commande et de contrôle tolèrent une démarche qualité, valorisant l'innovation, la créativité, la prise d'initiative locale et le travail en équipes non hiérarchisées, à la condition qu'elle se déroule à l'abri d'un projet. Force est de constater que ces dimensions clé de la culture qualité n'ont pas fondamentalement ni durablement imprégné des pratiques de management restées bureaucratiques. L'émergence d'une véritable 'culture qualité', un produit attendu de l'introduction de projets qualité, ne semble pas s'être produite au niveau organisationnel (Chapitre 7).

Nous procédons ensuite à la synthèse 'réaliste' de l'ensemble de nos études de cas (Chapitre 8). Nous en tirons les leçons sous la forme d'un enrichissement progressif de notre théorie initiale. Nous pouvons alors formuler une théorie améliorée, toujours intermédiaire et provisoire, dérivée de nos théories intermédiaires successives.

Discussion

Notre discussion s'organise autour de deux thèmes (chapitre 9).

Dans une première partie, nous discutons le potentiel et les limites de nos résultats et de l'approche réaliste de l'évaluation. Nous montrons que nos résultats sont des théories provisoires et incomplètes, deux caractéristiques d'une middle range theory. En dépit de ces limites, l'approche réaliste est potentiellement très riche pour interpréter les effets d'interventions dans des systèmes complexes. Elle se situe dans une perspective d'aide à la décision pour orienter l'action sur le terrain plutôt que dans une perspective de genèse de lois universelles. Elle représente une avancée méthodologique particulièrement pertinente pour la recherche sur les systèmes de santé dans un monde turbulent où de multiples initiatives se télescopent.

Dans une deuxième partie, nous discutons les conséquences de nos résultats pour le futur de l'assurance qualité dans les systèmes de santé. Les projets qualité étudiés ne parviennent pas à changer une culture organisationnelle bureaucratique qui compromet pourtant leur pérennisation. Nous envisageons alors les stratégies susceptibles de permettre à la culture qualité de s'épanouir et au contexte organisationnel d'évoluer en conséquence. Décentralisation et nouveau management public, en vogue hier et aujourd'hui, montrent leurs limites. Il faut probablement trouver un équilibre entre trois idéaux-types décrits par Freidson: l'idéal-type bureaucratique, malmené par les stratégies de débrouille locale, l'idéal-type du marché, valorisant l'initiative, et l'idéal-type professionnel, émergent mais encore embryonnaire en Afrique. Finalement, à côté des mécanismes du contrôle et de la compétition, un troisième mécanisme régulateur devrait prendre toute sa place: la confiance.

Introduction

For nearly two decades in Africa, quality circles, clinical audits, problem solving cycles and other quality projects have been implemented in public health services to improve quality of care. Challenging traditional managerial practices, these projects usually emphasized participatory approaches, local problem solving and change. At short term, evaluation shows improvement in programs and activities output. However the capacity to put quality at the heart of system's management should be considered as the genuine achievement of a quality assurance program. Did quality projects contribute to the adoption of quality management principles by health systems ?This is the question addressed in the present thesis.

Method

Our methodology belongs to the realistic evaluation paradigm conceptualized by Pawson and Tilley and focuses on the interaction between an intervention mechanism and its context in order to understand what works, for whom, in what circumstances and how ?Based on case studies in various contexts in Niger, Guinea, Morocco and Zimbabwe, we build a middle range theory, that explains organizational behavior towards quality management.

Results

Based on Mintzberg's models, we show the role of health care organizational configuration in resisting to quality management principles. We then explore the tension between the bureaucratic organization's command and control approach and the quality assurance approach promoting initiative and change through team work. Local initiative had to develop coping strategies to overcome bureaucratic constraints. Failing to do so, ambitions had to be reduced unless there was support from an external, yet legitimate institution. Public health systems of these countries, structured as command and control hierarchical organizations, allowed innovation, creativity, local initiative and non hierarchical relationships as long as they developed within the boundaries of a project. However, these key characteristics of a quality culture did not permeate routine management. The quality culture shift expected from quality projects does not seem to have happened at organizational level.

Discussion

We first discuss the potential and limitation of realistic evaluation which appear particularly relevant for complex health systems research. We then discuss consequences of our results on the future of quality assurance in health systems. Since quality projects fail to transform a bureaucratic organizational culture, which in turn undermines their sustainability, alternative strategies must be sought to promote quality culture and relevant organizational change. Decentralization and new public management show their limitations. We suggest a balance between three ideal-types described by Freidson: The bureaucratic ideal-type, challenged by local coping strategies, the market ideal-type, which is fashionable today and promote initiative, and the professional ideal-type, emerging and promising, yet still embryonic in Africa.

The recent political conflict in Zimbabwe has attracted the attention of policymakers, academics and the media alike in the neighbouring countries of the region, across the African continent and internationally. While the story of an ageing African liberation hero turned dictator who, through autocratic rule, has governed his country and his people to the ground in order to maintain power is captivating, a key element of the fascination is the critical diplomatic role played by South Africa from 2000 onward. Foreign policy in post-apartheid South Africa on paper is driven by human rights and democracy, conflict prevention and conflict resolution through peaceful means, and the promotion of African interests in world affairs. However, after observing South Africa’s involvement in the Zimbabwe conflict between 2000 and 2009, South Africa’s foreign policy appears to be propelled more by African solidarity and sovereignty, anti-imperialism, and a softer interpretation of preventive diplomacy than its international counterparts. Thabo Mbeki’s preventive diplomacy toward Zimbabwe during his presidency was slow to produce results, lacked transparency and frustrated many, yet, when examined under a preventive diplomacy theoretical lens, Mbeki’s policy did eventually garner success through the signing of the Global Political Agreement (GPA) and the formation of an inclusive government in Zimbabwe. This dissertation examines the role of preventive diplomacy in South Africa’s foreign policy toward Zimbabwe under Mbeki’s leadership and determines the point at which South Africa switched from an approach of preventive diplomacy to one of conflict resolution and conflict management. The concept of ‘preventive diplomacy’ is often focused on government-to-government relations or the high level diplomacy of intergovernmental organizations such as the United Nations (UN). Multi-track diplomacy expands on this traditional interpretation and considers the preventive diplomacy contributions of a variety of non-state actors to the practice of conflict prevention. This dissertation uniquely moulds the preventive diplomacy theoretical framework of Michael Lund with Kumar Rupesinghe’s concept of multi-track diplomacy to form a more comprehensive illustration of the role of preventive diplomacy in the approach of multiple actors towards the Zimbabwe conflict. The more inclusive preventive diplomacy theoretical framework is then applied to the conflict in Zimbabwe between 2000 and 2009. Through the application of a preventive diplomacy framework which incorporates the concept of multi-track diplomacy it is then possible to observe the South African government’s preventive diplomacy approach toward Zimbabwe first between 2000 and 2007 and then as mandated by SADC between 2007 and 2009 and finally compare it with the diplomacy of multi-track actors such as the UN, Zimbabwe-based and South African-based civil society organizations, the Zimbabwean Diaspora, religious groups, and financial institutions. The examination of the larger role of preventive diplomacy in the Zimbabwe conflict situation leads to the understanding that each diplomatic effort is interlinked. Therefore the culminating event of the South African government’s preventive diplomacy approach in the Global Political Agreement could not have been achieved without the preventive diplomacy efforts of a multitude of actors who were also committed to preventing violence and finding a lasting solution to the conflict in Zimbabwe.

The study explored transforming social development project management practice into delivering sustainable benefits for orphans in Zimbabwe, in particular and more generally, in southern Africa. The endemic failures to deliver basic services to vulnerable children despite increased efforts necessitated this enquiry. Applying multiple research methods in combination, namely, guided story-telling and interviews, document review and media tracking, and practitioner-experiential-action-research (PEAR), the study confirmed that orphans in Zimbabwe lived under conditions of extreme deprivation and vulnerability (EDV). Management of service delivery for orphans was dependent on unpredictable short-term donor funding, undermined by a hostile ‘adult-world’ and political environment, bad governance, poverty, and AIDS. Public service delivery and social welfare system in Zimbabwe had collapsed, marred by corruption. Programmes were not informed by an accurate understanding of orphans and their desperate carers. Social development intents were not practiced. The situation was conducive to “corrupting” the otherwise “spiritual” - responsible, astute and ambitious child. Within such a milieu, traditional project management designed for ordered situations became inappropriate. Based on new understanding of orphans and their service delivery milieu derived from research findings, I propose a systems-oriented project management framework based on “pluralism”, “holism”, “totality” and “experiential learning”. The framework takes a multi-paradigmatic approach to solving complex problems of vulnerable children, mixing positivist, interpretive, emancipatory and postmodern systems ideas. The framework requires a balancing of morality and scientific empiricism in order to attain sustainable child development. In this regard, the thesis proposes ‘moral capabilities’ and additional project management knowledge suitable to the challenges of orphans in southern Africa. The systems approach promotes comprehensive delivery of basic needs of orphans, and continuous improvement of their long term holistic development. According to the framework, success of projects is measured by accrued benefits from the perspective of orphans, and not that of service providers. For its application, the framework adapts the project-spiral cycle, replacing the project life-cycle, recognizing that the needs of orphans go beyond single short-term project cycles. The spiral cycle builds on the strengths of conscious-experiential-learning in service delivery, and on dialogue and collective consensus with poor communities targeted by service delivery management systems.

The Limpopo Province is a disaster-prone province, with drought being the most common natural disaster. From the year 2012 onwards, the province experienced extremely dry conditions that culminated in a severe drought in 2016. This negatively impacted the livelihoods of smallholder livestock farmers and the welfare of their livestock. The study investigated the coping strategies that were adopted by smallholder livestock farmers during drought conditions and the factors that were associated with animal loss during the drought that affected the region between 2014 and 2016. A randomly selected sample of 281 smallholder livestock farmers aged 18 years and older from the Greater Letaba Local Municipality participated in the study. Structured interviews, aided by questionnaires were used to collect the primary data. Proportions of categorical variables and the mean and standard deviation for continuous variables were computed and presented as tables and figures. A Poisson regression model was fitted to the data to identify factors that were significantly associated with loss of animals during the drought. More than half (55.50%; n=116) of the participants were made aware of the 2014–2016 drought through the agricultural extension officers, followed by 19.14% (n=40) who got to know about it through radio channels. More than half of the participants (58.29%; n=123) were aware of the impending drought. The most common support received from government agencies to help cope with the drought was in the form of animal feed (80%; n=124). Although most of the farmers (73.55%; n=114) benefitted from the support they received, slightly more than half (53.74%; n=151) did not cope well with the drought conditions. While Bellevue (B=-0.199; 95% CI: -0.380 -0.019) was negatively associated with loss of animals, Mokwakwaila (B=0.568; 95% CI: 0.405 0.731) had a strong positive association with loss of animals. Being married (B=-0.060; 95% CI: -0.305 0.183) or divorced (B= -0.035; 95% CI: -0.316 0.246) was negatively associated with loss of animals. Years of experience in farming (B=0.022; 95% CI: 0.010 0.033) and not receiving support during were strongly positively associated with loss of animals (B=0.324; 95% CI: 0.189 0.459). The low number of farmers who were aware of the impending drought and the large number of farmers who did not cope well suggests that many farmers in the area were not prepared for the drought. Groups such as widows, widowers and farmers who have many years of farming experience are high-risk groups and should be targeted for interventions in the event of a drought. More measures are needed to ensure that all agricultural centres are prepared and supported in event of a drought so as to minimise the impact of drought on local communities.
Die provinsie Limpopo is 'n rampgevoelige provinsie, met droogte as die mees algemene natuurramp. Vanaf 2012 het die provinsie uiters droë toestande beleef wat in 2016 op 'n ernstige droogte uitgeloop het. Dit het 'n negatiewe uitwerking gehad op die lewensonderhoud van kleinboere en die welstand van hul vee. Die studie het ondersoek ingestel na die hanteringstrategieë wat deur veeboere in kleinvee tydens droogtetoestande aangeneem is, en die faktore wat verband hou met diereverlies tydens die droogte wat die streek tussen 2014 en 2016 geraak het. 'N Lukraak geselekteerde steekproef van 281 kleinboere van 18 jaar en ouer van die Greater Letaba Local Munisipaliteit het aan die studie deelgeneem. Gestruktureerde onderhoude, gehelp deur vraelyste, is gebruik om die primêre data in te samel. Verhoudings van kategoriese veranderlikes en die gemiddelde en standaardafwyking vir deurlopende veranderlikes is bereken en as tabelle en figure aangebied. 'N Poisson-regressiemodel is op die data toegepas om faktore te identifiseer wat beduidend verband hou met die verlies aan diere tydens die droogte. Meer as die helfte (55,50%; n=116) van die deelnemers is bewus gemaak van die droogte 2014–2016 deur die landbouvoorligtingsbeamptes, gevolg deur 19,14% (n =40) wat dit via radiokanale leer ken het. Meer as die helfte van die deelnemers (58,29%; n=123) was bewus van die dreigende droogte. Die mees algemene steun van regeringsinstansies om die droogte die hoof te bied, was in die vorm van veevoer (80%; n=124). Alhoewel die meerderheid van die boere (73,55%; n=114) voordeel getrek het uit die steun wat hulle gekry het, het die droogtetoestande nie goed hanteer nie (53,74%; n=151). Terwyl Bellevue (B= -0.199; 95% CI -0.380 -0.019) negatief geassosieer is met verlies aan diere, is Mokwakwaila (B= 0,568; 95% CI 0,405 0,731) sterk positief geassosieer met verlies aan diere. Om getroud te wees (B= -0.060; 95% CI -0.305 0.183) of geskei (B= -0.035; 95% CI 0.316 0.246) was negatief geassosieer met verlies aan diere. Jare se ondervinding in die boerdery (B=0,022; 95% CI 0,010 0,033) en om nie ondersteuning gedurende te ontvang nie, was sterk positief geassosieer met die verlies van diere (B=0.324; 95% CI 0.189 0.459). Die lae aantal boere (ongeveer die helfte) wat bewus was van die dreigende droogte, dui daarop dat baie boere in die omgewing nie voorbereid was op die droogte nie. Groepe soos weduwees, wewenaars en boere met baie jare se boerdery-ervaring, is hoërisikogroepe en moet geteiken word vir ingrypings in die geval van 'n droogte. Meer maatreëls is nodig om te verseker dat alle landbousentrums voorberei en ondersteun word in geval van 'n droogte om die impak van droogte op plaaslike gemeenskappe te verminder.

An ever-increasing number of companies have bought into the Africa investment proposition, and are now focusing on how to effectively execute a growth strategy in what remains an inherently complex environment to do business. African markets are progressively open for business. Despite perceptions of elevated risk, in many ways, the continent is no different to others. Sound business practices enable well-run firms to convert business strategies into actual results, regardless of where these firms are placed. The research shows that AngloAmerican Platinum investment decisions were based on more than cost-benefit returns. There was more to Anglo’s case for investing in Zimbabwe. Political knowledge and organisational structure and national culture were implicitly part of AngloAmerican Platinum decision making. Political criteria have become increasingly entwined with business decisions in emerging economies in Africa where medium-to-long-term stability is questioned. Supply Chain Risk Management (SCRM) plays a major role in successfully managing business processes in a proactive manner. Supply chain risk has multiple sources including process, control, demand, supply and environment. Supply chain management, faced with these risks, requires specific and adequate responses such as techniques, attitude and strategies for management of risk. Since every organisation strives for success and uninterrupted operations, efficient supply chain risk management is crucial. Supply chain risk management has the ability to achieve a competitive advantage where a risk is identified, estimated, managed and controlled. The study assesses development and implementation of supply chain risk management strategies in African markets, by using UNKI Platinum mine in Zimbabwe as a case study. This approach provides insight to a real-world setting that could be applied in a broader context. The aim was met by interviewing nine senior managers and executives who directly or indirectly participated in the development and implementation of supply chain risk management at UNKI Platinum mine. Furthermore, two suppliers and two industry experts were interviewed to ensure validity of the research case study. The data from the interviews were combined with data from the literature review. The study concludes with a list of factors that can be deemed to be important to the development of entry-strategies into Zimbabwe. Moreover, another list of themes emphasizing the elements of importance in the development and implementation of supply chain risk management strategy were identified. In essence, the leanings are used to propose a conceptual framework for supply chain risk management strategies in Africa.

Currently, there are environmental issues the world is facing which include global climate change, ozone depletion, pollution, high consumption of resources and increasing amounts of solid waste. Tourism is one of the largest industries and it is an important economic tool. However, it also has many negative effects on the environment. Hotels as one of the tourism industry’s component parts have a significant impact on the environment. From an environmental perspective, hotels consume a large amount of resources such as water and electricity as they make efforts to provide physical comfort to guests. In addition, hotels generate large quantities of waste, which is one of their most visible effects on the environment. Hotels also make a significant contribution to greenhouse gases which are a cause of concern due to the ozone layer depletion. Many hotel customers have become aware of the environmental damages and wasting of environmental resources caused by hotels and they now look for hotels that follow eco-friendly practices. This has brought increasing pressure on hotels to implement more green initiatives. There is limited documented information on green management among hotels in South Africa and in Zimbabwe. While the number and range of impacts hotels have on the environment suggests an urgent need to address them, the environmental management initiatives in these hotels are scantly addressing these green issues and this study is the first to address these issues. The goal of the study was therefore to develop a green management framework for hotels in South Africa and Zimbabwe so that these developing countries may contribute significantly in mitigation of the negative environmental effects. To achieve this goal, two literature chapters addressed the issue of green management and how it can be implemented by hotels. A qualitative research was then carried out employing the case study strategy to collect data from hotel managers in South Africa and Zimbabwe (four in Zimbabwe and four in South Africa). Data was collected using personal interviews involving a direct meeting of the interviewer and the interviewee. Personal interviews were carried out in Zimbabwe. In South Africa, data was collected using telephone interviews. In both Zimbabwe and South Africa, data was recorded on a digital voice recorder. Data was later transcribed and then analysed using the content analysis method. Some of the main findings of the study are that, while some perceptions of managers about the green management concept are consistent with a number of aspects emphasised in literature, some hotel managers do not fully understand or grasp what the concept of green management entails. This indicates that a gap exists between managers’ knowledge and what green management really means, at least according to literature. The study has also established that in most hotels, there is unavailability of green management policies, suggesting that there is a lack of knowledge about the importance of a green management policy amongst hotel managers in these two developing countries. The key contributions of this study are that, it provides insights on the current debate on green management in hotels as revealed through green management initiatives implemented in hotels in South Africa and Zimbabwe. Secondly, the study makes a contribution by doing a supply side analysis and identifying the views of hotel managers with regard to green management. This study also contributed by proposing a green management framework for hotels – an aspect that is currently lacking in the existing literature especially from a developing country point of view. The green management framework proposed has guidelines for implementation. The hoteliers in the two countries will thus benefit from the framework and will be in a position to implement green initiatives to mitigate the negative impacts hotels have on the environment.

By presenting case studies from the village of Mahenye in Zimbabwe and the five villages of the Okavango Community Trust in Botswana, the study looks beyond the objectives, discourse and contests of policy and undertakes an investigation of what actions rural people are undertaking inside the institutions established by policy makers, and of governance outcomes at the local level. These case studies reveal that unfettered devolution can lead to elite capture and the perpetuation of poverty
that rural communities themselves have agency and the ability to exercise it
and that there is limited and shrinking political space in both countries which is reducing opportunities for rural communities to engage with political processes. The Botswana case studies demonstrates that an imported and imposed devolutionary initiative which lacks links to higher levels of governance can reduce political space at local levels. The Zimbabwe case study demonstrates that political space may be more effectively created through decentralisation. The lesson drawn from these case studies is that institutional arrangements and roles should be determined by context specific issues and circumstances and move beyond the structural determinism that has characterized much of the CBNRM debate to date. The study concludes with policy recommendations. These include the need for recognition of the synergy between CBNRM and democratisation as mutually reinforcing processes and the need to be context-specific...

Quality assurance is increasingly becoming an important aspect of higher education institutions in developing countries, as expressed in the development of relevant policies, structures and systems at national and institutional levels. This thesis critically examines the nature of quality assurance policies and practices in selected universities in the Southern African Development Community (SADC), as well as the factors that shape these policies. Through a close examination of these policies and practices, the thesis explains why some universities realise better quality than others, even though they fall within the same geographical region and share relatively similar historical legacies. Although this study was largely qualitative, it did not preclude quantitative dimensions. Integrating the two approaches made it possible not only to triangulate data, but also to engage in multidimensional analysis of some of the phenomena under investigation. While debates in the literature locate quality assurance within internal and external discourses, this does not sufficiently explain the tensions that were observed amongst the various stakeholders within institutions, especially between management and academic staff. The manner in which institutional policies were developed, the role academic staff played in the process, and the reporting lines associated with institutional quality assurance arrangements, are reflected in staff perceptions on whether or not they regarded the policies as internal to the academic community and the extent to which they own the policies. The main contribution of this thesis to debates on quality assurance is its revelation of the complexities that arise in institutional policy making as a result of the highly differentiated nature of the academy. This aspect points at the need for institutions to pay particular care in adopting most appropriate strategies that privilege the organic development of policies within institutions. On the whole, institutions were mainly preoccupied with developing quality assurance policies and systems that are comparable to international standards, hence the heavy reliance on external/international expertise in doing so. Whilst this is not necessarily a iii bad thing, the quality assurance systems that were developed did not take into account the contextual peculiarities of the studied institutions. A direct consequence of this was the development of policies and mechanisms that are more concerned with standardisation of procedures than with enhancement of academic practice. Such quality assurance systems have not resulted in the self-improvement of institutions. The establishment of quality assurance policies and the putting in place of structures and procedures are necessary but not sufficient conditions for enhancing academic practice in universities.

Recurring drought conditions have always been an endemic feature of climate in South Africa, limiting maize development and production. However, recent projections of the future climate by the Intergovernmental Panel on Climate Change suggest that due to an increase of atmospheric greenhouse gases, the frequency and severity of droughts will increase in drought-prone areas, mostly in subtropical climates. This has raised major concern for the agricultural sector, particularly the vulnerable small-scale farmers who merely rely on rain for crop production. Farmers in the Luvuvhu River catchment are not an exception, as this area is considered economically poor, whereby a significant number of people are dependent on rain-fed farming for subsistence. This study was therefore conducted in order to improve agricultural productivity in the area and thus help in the development of measures to secure livelihoods of those vulnerable small-scale farmers. Two drought indices viz. Standardized Precipitation Evapotranspiration Index (SPEI) and Water Requirement Satisfaction Index (WRSI) were used to quantify drought. A 120-day maturing maize crop was considered and three consecutive planting dates were staggered based on the average start of the rainy season. Frequencies and probabilities during each growing stage of maize were calculated based on the results of the two indices. Temporal variations of drought severity from 1975 to 2015 were evaluated and trends were analyzed using the non-parametric Spearman’s Rank Correlation test at α (0.05) significance level. For assessing climate change impact on droughts, SPEI and WRSI were computed using an output from downscaled projections of CSIRO Mark3.5 under the SRES A2 emission scenario for the period 1980/81 – 2099/100. The frequency of drought was calculated and the difference of SPEI and WRSI means between future climate periods and the base period were assessed using the independent t-test at α (0.10) significance level in STATISTICA software. The study revealed that planting a 120-day maturing maize crop in December would pose a high risk of frequent severe-extreme droughts during the flowering to the grain-filling stage at Levubu, Lwamondo, Thohoyandou, and Tshiombo; while planting in October could place crops at a lower risk of reduced yield and even total crop failure. In contrast, stations located in the low-lying plains of the catchment (Punda Maria, Sigonde, and Pafuri) were exposed to frequent moderate droughts following planting in October, with favorable conditions noted following the December planting date. Further analysis on the performance of the crop under various drought conditions revealed that WRSI values corresponding to more intense drought conditions were detected during the December planting date for all stations. Moreover, at Punda Maria, Sigonde and Pafuri, it was observed that extreme drought (WRSI <50) occurred once in five seasons, regardless of the planting date. Temporal analysis on historical droughts in the area indicated that there had been eight agricultural seasons subjected to extreme widespread droughts resulting in total crop failure i.e. 1983/84, 1988/89, 1991/92, 1993/94, 2001/02, 2002/03, 2004/05 and 2014/15. Results of Spearman’s rank correlation test revealed weak increasing drought trends at Thohoyandou (ρ = of 0.5 for WRSI) and at Levubu and Lwamondo (ρ = of 0.4 for SPEI), with no significant trends at the other stations. The study further revealed that climate change would enhance the severity of drought across the catchment. This was statistically significant (at 10% significance level) for the near-future and intermediate-future climates, relative to the base period. Drought remains a threat to rain-fed maize production in the Luvuvhu River catchment area of South Africa. In order to mitigate the possible effects of droughts under climate change, optimal planting dates were recommended for each region. The use of seasonal forecasts during drought seasons would also be useful for local rain-fed maize growers especially in regions where moisture is available for a short period during the growing season. It was further recommended that the Government ensure proper support such as effective early warning systems and inputs to the farmers. Moreover, essential communication between scientists, decision makers, and the farmers can help in planning and decision making ahead of and during the occurrence of droughts.

Water is a symbol of life. It affects all organisms on earth and its importance is emphasised in times of drought. The human population growth places more demands on our natural resources. As pressures on the available water increases, more measures are required to utilise water sustainably. South Africa is classified as a water stressed country with less than 1700 cubic meters of water available per person per year. Rand Water supplies water to approximately 11 million people in Gauteng. During times of drought, restrictions imposed are aimed mainly at the broader Green Industry. This research investigated international strategies, existing restrictions in Gauteng, and undertook a survey within the Green Industry to determine the most appropriate response. This research proposes a new water supply shortage response plan for Rand Water in Gauteng with a total of four levels of restrictions implemented at different stages of water stress in the system.

Climate change and variability have great impact on the hydrological cycle and consequently on the availability of water resources. Variations in temperature and precipitation trends that are occurring are a consequent of the increase in the concentrations of greenhouse gases, which are subsequently affecting the hydrological cycle. This in turn affects water quantity and quality, which is essential for agriculture, domestic and industrial uses. This study, done in Elliot Town and the surrounding areas of Sakhisizwe Municipality in the Eastern Cape Province of South Africa, evaluates how climate change and variability is affecting water availability and its quality in the town. The impact climate change and variability on agricultural production is also assessed. Remote Sensing, Geographic Information Systems (GIS), databases and some statistical packages have been used to collect, analyse and create spatial maps used to derive concrete conclusions. The methods used aided in spatially analysing the changes in temperature and rainfall along the years and make a comparative analysis. The study has shown that the spatial changes in the amount, intensity and frequency of rainfall affects the magnitude and frequency of stream flows; consequently, increasing the intensity of floods and droughts that have been recurring in the last few decades. The municipality is more affected by climate variability than change, and the resultant extreme climate events are affecting the water resources resulting in domestic water cuts, poor water quality and low agriculture productivity. This study recommends the importance of an awareness campaigns on climate change and variability and their effect directed towards the community, especially on novel water harvesting technologies. The study also highlights the importance of a robust early warning system to prepare the community in case of a climate shock, which is an area that needs further research.

This research focused on evaluating and comparing the perceptions, water-use behaviour, water conservation awareness and overall water stewardship of participants residing in Hammanskraal and Atteridgeville who have experienced intermittent water supply in their domestic households – due to either water contamination incidents caused by dilapidated infrastructure or water restrictions implemented by the City of Tshwane Metropolitan Municipality during the 2016–2017 drought in the Gauteng Province. The research concluded that the municipality needs to implement proactive water conservation awareness initiatives on an ongoing basis to reduce high water demands and to create a culture of water stewardship, especially in Atteridgeville. Transparent communication is also required from the municipality to instil the necessary trust among the public. It is recommended that the municipality attends to water leaks and ongoing complaints from the public timeously to reduce the current apathy from the public against reporting water-related issues and to ultimately ensure compliance to water restrictions.
