Modelling tropical soil water regimes in semi-arid environments

Van der Meer, Frans-Bauke Willem January 2000 (has links)
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 assessment of disaster risk reduction strategies in dairy supply chains in Zimbabwe

Chari, Felix January 2017 (has links)
Submitted in fulfilment of the requirements for the Degree of Doctor of Technology: Public Management, Durban University of Technology, 2017. / Disasters are on the increase globally with devastating effects. The devastation caused by these disasters in various countries highlights the need for increased commitment and investment, by government and various stakeholders, in disaster risk reduction. This study investigated disaster risk reduction strategies in Zimbabwe’s dairy supply chains. The study was initiated on the premise that Zimbabwe is at high risk and vulnerable to natural and man-made hazards. The study is set in the backdrop of declining output across all agricultural sectors evident particularly in the dairy farming sector that has seen inadequate supply of raw milk and dairy products by local producers in Zimbabwe. This study therefore sought to assess the collaborative strategies by government, dairy organisations and dairy supply chain stakeholders to reduce disaster risks in the dairy industry. The study employed a mixed-method approach (qualitative and quantitative) to investigate collaborative disaster risk reduction strategies used by dairy supply chain stakeholders to avoid supply chain disruptions. The study used a sample size of 92 dairy farmers, from major milk producing regions of Zimbabwe, for the questionnaire. The Cronbach alpha test for reliability showed a reliable questionnaire. Furthermore, the study used information from key informants, 30 retailers and 20 dairy officers for one-on-one interviews. Quantitative data was analysed using STATA (version 13). OLS regression analysis was done and results were compared with those of the Tobit models as a test for robustness of the results. Qualitative data was analysed using thematic analysis derived from observations and interviews and descriptive statistics presented in tables and bar charts. Notable in the literature reviewed is lack of coordination amongst stakeholders in strategies to reduce disaster risks in dairy supply chains in Zimbabwe. This study adopted a collaborative proactive framework and tested it as a strategy to reduce disaster risks in dairy supply chains. The study gives four major findings. Firstly, dairy supply chains in Zimbabwe were exposed to a number of risks which are: international competition, competition from local giants, financial risks, political risks, technological risks, environmental risks and production risks. Secondly, findings from regression analysis indicated that an overall index of disaster risks significantly influenced job losses, food security, milk productivity and growth of ventures in dairy businesses. Thirdly, there were isolated cases of planned coordination by stakeholders in the industry to reduce the negative effects of disasters across the supply chain. There was collaboration among dairy farmers, processors, NGOs, and government departments of agriculture and environment. Fourthly, an index of collaborative strategies regressed against dependent variables of variables of supply chain cost, lead time milk sales, and variety and quality of milk demonstrated that collaborative strategies in dairy supply chain significantly influenced supply chain costs and variety and quality of milk and milk products. It is expected that the study will assist government in the formulation of public policies for the dairy sector leading to improved access to high quality raw milk and milk products for consumers thus resulting in improved nutrition and food security for the people of Zimbabwe. Policy recommendations highlight that instead of the current maximum of the 5 year lease given to white commercial farmers, the government should consider issuing out long term leases in order to protect long-term investment in dairy projects. Government should, therefore, create an enabling environment for stakeholder partnerships in the dairy sector. / D

Facilitating reconciliation in divided communities in Mashonaland Province, Zimbabwe

Shonhiwa, Kudakwashe January 2016 (has links)
Submitted in fulfillment of the requirements of the degree of Doctor of Philosophy: Public Management (Peacebuilding), Durban University of Technology, Durban, South Africa, 2016. / Conflicts in Zimbabwe have triggered communities to be divided along political party lines. Violence has been prevalent and this has intensified economic ruin and social polarity. In high density urban areas this violence continues to divide communities. The overall aim of this research study was to facilitate reconciliation in divided communities in Mashonaland province, Zimbabwe with the Alternative for Violence Project (AVP), an international non-profit organisation that provides experiential training to individuals and organisations in nonviolence and pre-emptive conflict resolution. The objectives of the study were to explore the underlying causes of violence in Zimbabwe, its consequences and impact since 2000, and also to explain the concepts of conflict transformation, forgiveness and reconciliation as used by AVP. In addition, the study explored AVP’s outcomes in different contexts and examined its potential as an instrument for reconciliation by implementing several AVP workshops in the divided communities. Hatcliffe, a high density area outside Harare, was used as a sample population for the study which drew from Lederach’s theory of conflict transformation and from Azar‘s model of protracted social conflicts. The researcher used a qualitative approach in the field research and interviewed both the victims and perpetrators of violence as well as elected leaders in the Hatcliffe community. The main findings of the study were that reconciliation efforts are best begun with an orientation towards peace-building for community residents and local ownership of all reconciliation processes. All community members directly or indirectly involved in a conflict situation are critical to reconciliation efforts and third parties must ensure that these people are empowered to make their own decisions. The study concluded that AVP is an effective tool which can be used to change people’s perspectives about conflict and that creating safe spaces where people can articulate their issues in a relaxed atmosphere can be deeply healing. Because the findings are not disconfirmed by prior theories and research based on similar efforts, but rather add to knowledge already gained, one can assume that there also is a degree of external validity to the study. / D

Conflict and the resolution process in Zimbabwe from 2000 to 2013

Mutambudzi, Anywhere January 2016 (has links)
A thesis submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, in fulfillment of the requirements for the degree of Doctor of Philosophy March 2015 / The timing of conflict resolution efforts is important in identifying when an intervention is likely to succeed according to ripeness of conflicts theory (Zartman, 1985). Although the ripeness theory appears to be a great contribution to the conflict resolution doctrine, there is no scholarly consensus on its plausibility with criticisms that are centred on: a contest on the variables that should help in its identification; low predictability; lack of cross-case generalisations; and, methodological weaknesses inherited from rational and public choice theories. The study took the position that conditions creating ripeness should be expanded beyond what is currently obtaining in literature, can help in determining the formula for resolution and indicate what to do in the implementation of the agreement so reached. To interrogate the theory’s plausibility, interpretivism was used to gather evidence from the case - the conflict that prevailed in Zimbabwe from 2000 to 2013 - to extrapolate implications for the ripeness theory and suggest improvements through paradigm complementarity. Although the external dimension of the conflict in Zimbabwe remained unaffected, ripeness was found in its domestic setting deriving from the indecisive/disputed elections of 2008 and the threat of a failed economy that triggered a Southern African Development Community intervention and offered a cue to the formula for resolution - the Global Political Agreement. Shared political legitimacy in the Global Political Agreement however saw that ripeness diminishing and it had vanished by 2013, although the conflict which by 2013 was yet to realise complete resolution, was to a large extent transformed to lower levels of hostilities with dysfunctionality temporarily arrested. Ripeness proved to be a product of both perceptual and structural variables that change in intensity over time, thus affecting the implementation of agreements that arise from ripeness. The study proved that ripeness theory in its expanded form is a viable strategic tool in conflict resolution, though success as in military doctrine depends on the accurate identification of the variables creating ripeness, timely intervention and a fitting operational plan to effectively exploit the opportunities so created. / MB2016

An exploration of the effect of world politics on SADC's capacity to manage and resolve violent conflict

Matsanga, Mavis January 2015 (has links)
The rise of International Non-Governmental Organisations (INGOS) in the post-Cold War era in Africa exerted pressure on conflict resolution mechanisms as governments responded to perceived and real pressure from external, mainly Western countries. INGOs are well resourced and conduct ‘humanitarian’ and other work funded by donors. The issue of funding is critical to control and legitimacy. It is also tied to achievement of intended goals. The study explores the relationships and in some cases conflict between Western NGOs in Zimbabwe and the government during the period when the latter was experiencing diplomatic estrangement with Western countries. The qualitative study seeks to establish whether INGO operations were influenced by political relations. The researcher interviewed twenty experts in NGO and governmental operations using an interview guide. Data was collected and entered into Nvivo software where it was thematically analysed. The major findings of the study are that the political strand is the main relational context that determined the relationship between the government and INGOs. INGOs were viewed as active conflict drivers mostly due to the bias towards certain political parties and being conduits of Western initiatives. Local conflict resolution mechanisms were also established to be inadequate. The study recommends that the government of Zimbabwe needs to work on maladministration and resolve differences with Western countries. Local NGOs and INGOs should not meddle in politics in order to have a trustworthy relationship with government while donor funds are more appreciated when channelled through governments.

An investigation into effectiveness of household solid waste management strategies in Harare, Zimbabwe

Mandevere, Benjamin 20 April 2016 (has links)
The main objective of the study was to investigate the effectiveness of the strategies employed by the City of Harare in household solid waste management. To achieve these, structured questionnaires, interviews, observations and focus group discussions were employed in data gathering together with secondary data. The study was conducted in Harare’s low, medium and high density income suburbs. Findings revealed that organic solid waste constituted the largest proportion of waste generated in Harare and other forms are also generated yet their collection is very minimal. Residents resort to illegal night dumping, resulting in the proliferation of associated diseases. In light of these findings, it was recommended that waste collection entities be capacitated, people be educated on waste recycling, reduction and reusing. A commission was to be put in place to ensure proper enforcement of waste legislation, effective and sustainable day in running of household solid waste management in the city / Environmental Sciences / M.Sc.

Levels of selected gaseous pollutants in ambient air in the vicinity of a chemical industry, Kwekwe, Zimbabwe

Simbi, Joseph January 2015 (has links)
Thesis (MTech (Environmental Management))--Cape Peninsula University of Technology, 2015. / The integrity of natural air has been compromised due to the deposition of chemical, biological and particulate substances from natural and anthropogenic sources. Adverse health consequences arising from the exposure of plants, animals and human to elevated atmospheric concentrations have been reported severally. The ambient baseline levels of many air contaminants in urban and industrial layouts of many Africa cities, especially Zimbabwe have not been fully characterized. Information on levels of these contaminants and their real time variability is therefore scarce and scanty. In this study, the ambient air concentration levels of selected gaseous pollutants in the vicinity of a fertilizer production facility in Zimbabwe were investigated. Nine sampling stations were systematically and randomly identified for the measurement of selected air pollutants (SO2, NO2, and NH3) the fertilizer production factory to capture air quality data on all wind directions. The electrochemical Drager Sensors which rely on electrochemical measuring transducer for measuring concentration of gases under atmospheric conditions was used for the measurement of NH3, SO2, and NO2. The ambient air monitored was allowed to diffuse through a membrane into the sensor liquid electrolytes, containing a sensing electrode, a counter electrode, a reference electrode, and an electronic potentiostat-circuit which ensures constant electrical voltage between the sensing electrode and the reference electrode. The flow of electrons, generated by the reaction is proportional to the concentration of the measured gas. The observed concentrations of NH3, SO2, and NO2 measured within and around the study site were very variable. Levels of NH3 ranged between 0.36 - 7.36 ppm; corresponding values for SO2 and NO2 were 0.02 - 84.61 ppm and 0.61 - 34.78 ppm respectively. These concentrations were significantly higher (p < 0.05) than measured (NH3; 0.01 - 0.05 ppm: SO2; 0.03 - 0.18 ppm: NO2; 0.17 - 1.30 ppm) at the control sampling station about 5 km from the industry. Isokinetic and dissipation of the measured gases, governed by the processes of molecular diffusion and convection, confirmed a common pattern of distance dissipation. Thus, the cloud concentrations of NH3, SO2, and NO2 within the facility were higher than observed distances away from the fertilizer factory. / Zimbabwe Presidential Scholarship

In pursuit of sustainability of not-for-profit theatre organisations: a case study of Savanna Trust in Zimbabwe

Maposa, Daniel January 2016 (has links)
A research report submitted in partial fulfilment of the requirements for the degree of Master of Arts In the field of Cultural Policy and Management Faculty of Humanities University of Witwatersrand, 2016 / Sustainability is a concept that has received a lot of attention in arts management discourse. It is also a concept that many theatre organisations grapple with both in developing and developed countries. Practitioners, managers and scholars have been trying to find solutions to the growing need for sustainability of arts organisations. While a number of strategies have been proffered, most of them have been focusing on financial sustainability. This study argues that if arts organisations are to achieve sustainability, the issue must be looked at from a broader, holistic perspective. In pursuing a holistic perspective on sustainability, the overarching argument is that for a theatre organisation to achieve sustainability, it must be guided by four pillars. These pillars are artistic vibrancy, community relevance, capitalisation and good governance. The focus of the study is on not-for-profit theatre organisations operating in Zimbabwe. Savanna Trust, a theatre organisation based in Zimbabwe is used as a case study. The study starts by looking at the external and internal challenges that are faced by theatre organisations operating in unstable socio-political and economic environments such as Zimbabwe. These challenges are some of the major impediments to organisations that pursue sustainability. The study then uses the four pillars to examine Savanna Trust and its capacity to become a sustainable organisation. This study recommends some strategies that not-for-profit theatre organisations can implement in pursuance of sustainability. It is hoped that the study will also contribute to a body of academic literature on theatre and sustainability with a specific focus on not-for-profit theatre organisations. / GR2017

Acting out the myths : the power of narrative discourse in shaping the Zimbabwe Conflict of Matabeleland, 1980-1987.

Stauffer, Carl Swarr. January 2009 (has links)
This thesis interrogates the Matabeleland disturbances of 1980-1987 by analysing the conflict narratives promulgated by the ZANU-PF and how these narratives directly impacted the socio-political construction of violence that was enacted during that period. Of critical relevance is the interplay between the revolutionary narratives manufactured and imposed by the ZANU-PF regime and the myriad of contrasting, yet subjugated counter-narratives that were formulated as alternative resistances by the recipient communities. Through in-depth interview and document analysis methodologies, this research deconstructs the generative nature of scripted violence through the exploration of five salient themes employed by the ZANU-PF to produce its political meta-narrative: Ethnicity, Nationalism, Loyalty, Legitimacy and Unity. This study explores the power and function of narrative discourse in the formulation of ethnic identities, nation-state ordering, historical exclusion, political discipline, and social uniformity. The premise of this dissertation suggests that durable peace in Zimbabwe will only be realised to the degree that the silenced victims of the Matabeleland massacres are afforded a public voice and a sustained recognition in the historic, collective memory of that nation. / Thesis (Ph.D.)-University of KwaZulu-Natal, 2009.

Community participation in environmental management and the fulfillment of household food security : a case study of Sanale community in Insiza District, Zimbabwe.

Sibanda, Mbizo Edward. January 2005 (has links)
Current development thinking revolves around sustainable development, which must be achieved at every level of society in order to attain sustainable livelihoods. One way of fulfilling this, is by ensuring that human beings are put at the centre of the development process, that is, development should be woven around people and not people around development. In other words development should be participatory and people should have the opportunity to invest in the development of their capabilities in various facets of their life. This notion was applied to the Sanale community of Insiza District of Zimbabwe. The community in question mobilized itself around projects as a way of tackling mounting environmental and food security problems. The thrust of this thesis therefore is to establish how community participation enhances environmental management and how it can also lead to improvement of food security of the community in question. The study adopted a qualitative research paradigm which entails the non-numerical examination of phenomena focusing on the underlying meanings and patterns of relationships. This is because the study utilized a case study method as a way of gaining an in-depth understanding of the community. Hence, in order to obtain information on the activities of the community in as far as conservation and livelihood issues are concerned fieldwork was undertaken and interviews conducted with household respondents and key informants. A focus group discussion was also conducted with community members involved in programme activities. Review of documents and literature such as journals, occasional papers, proposals , brochures, organizational reports and internet search was conducted in order to obtain information from secondary sources and gain insights from the literature on the subject matter. Also the observation method was used to cross check claims made by both community and key informants with regard conservation and livelihood endeavors by the community. Research findings indicate that the Sanale community managed to pull itself out of a precarious position characterized by environmental degradation and constant food deficits. This was achieved through self-mobilisation and participation in project activities. Such initiatives impacted positively on the lives of poor Sanale villagers including women. It also emerged that projects in Sanale have led to full realization of human capabilities as the community in question presides over their own decisions, have cultivated the right attitude to plan and work resulting in natural resources conservation and fulfillment of livelihood needs. In short, participation of the community in their own development has been a key factor in the success of their projects. Such success can be measured in terms of the improvement of the situation of the community after the inception of projects as compared to before project inception. This was also made possible by stakeholders such as NGOs, Government departments, CBOs and local leaders who played a facilitator role. The study concluded that interactive participation and self-mobilisation of communities is a necessary ingredient for resource conservation and improvement of household food security. However, it emerged in the study that there is need to strengthen institutional structures, national or local, to allow full integration of environmental and developmental issues, at all levels of decision-making. Also important was the sustenance of the Sanale project beyond the life of grants such as GEFSGP and ERF. Further, fostering community participation in all stages of the project cycle is important for the project and community. Above all, the issue of sustainability should preoccupy such projects and multi-stakeholder partnerships should be encouraged if rural projects are to last into the foreseeable future. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, 2005.
