Barriers and enablers to water access and community wellbeing in the Onesi constituency of Namibia: the case of Okalonga B and Onandjandja villages

Shooya, Omagano Ndapewa January 2017 (has links)
The scarcity of water and especially the lack of safe drinking water have been accepted as amongst the most serious challenges facing the twenty-first century. The lack of access to water is a global problem that faces between 460 million to more than 1 billion people as a result of an increasing demand for water as well as a diminishing supply of water resources. The lack of access to potable water poses a great constraint on the societal and individual well-being for the inhabitants of the semi-arid regions of southern Africa and the key area needed to improve the sustainable development of water resources and services has been identified as water governance. The aim of this research is, therefore, to understand how access to potable water affects the well-being of communities living in the Cuvelai-Etosha basin in Namibia and to understand how these communities participate in water governance. The Okalonga B and Onandjandja villages were used as case studies.The objectives of this study are to examine how water is accessed and determine what the barriers are in accessing potable water, to examine how the well-being of the communities in the two villages is affected by water access and to explore how communities are engaged in water governance. The overall methodology of the study was based on a qualitative approach to case study research. Interviews were conducted at the household level, the constituency and regional levels using semi-structured interview guides. The study found that the communities of Okalonga B and Onandjandja access water through hand-dug wells, private and communal taps, Etaka dam and Oshana, and boreholes. A total of 6 barriers to accessing potable water were identified. These included distance to communal taps, amount of water one can carry, administration of water infrastructure, maintenance of water infrastructure, ability to pay the set water fees and specific times allocated for collecting water. The barriers to accessing potable water negatively affect the well-being of communities. Communities felt that they would have better economic opportunities if they had access to potable water which would in turn improve their well-being and livelihood opportunities. Furthermore, the study found that community participation in water governance was poor.

Building the Western Cape farmers resilience to climate change: assessing the usefulness of credibility salience and legitimacy framework in linking climate change adaptation information into action

Siziba, Bridget 28 July 2023 (has links) (PDF)
Despite the increasing availability of scientific information to support climate change decisionmaking for farmers' resilience to the global challenge, a persistent gap exists between knowledge development and its application in decision-making. This is exerting pressure on science to develop more actionable or decision-relevant scientific information to support planning, and climate change decision-making. In the context of communicating climate change adaptation information, this study examined the usefulness of the Credibility, Salience, and Legitimacy (CSL) framework, otherwise known as the knowledge system framework (Cash et al., 2003), in bridging the disconnect between information production and its use in decision-making by commercial farmers in South Africa's Western Cape Province. The study was underpinned by Cash et al.'s 2003 boundary work theory, which argues that there are boundaries at the science and farmer interface which can be managed by knowledge systems employing the CSL framework in knowledge production. As such, the researcher undertook and examined the Western Cape's agricultural climate change response strategy known as the "SmartAgri" Plan, wherein scientists and agricultural experts developed case studies and regional commodity briefs, a proxy of climate adaptation information, to support farmers' resilience to climate change. The research looked at how these communication outputs are actionable in connection to users' perceptions of the credibility, salience, and legitimacy of this knowledge. The research consisted of an online focus group discussion with four SmartAgri scientists and agricultural experts as the producers of the information, as well as semistructured telephone interviews with 11 Western Cape commercial farmers, as users of climate change adaptation information. Findings from the interviews suggest that while there have been efforts to produce credible knowledge for enhanced awareness of climate change and its impacts on the Western Cape province's agricultural sector, availability of salient and legitimate climate change adaptation information remains a challenge at the science-farmer interface. Factors such as, limited experiential evidence, disparities in the scale and resolution of climate projections, the absence of financial support to commercial farmers and limited involvement of farmers in the development of climate change adaptation information, continue to undermine the actionability of climate change adaptation information in the areas studied. As a result, spanning the boundary between knowledge and action has been a challenge. Nevertheless, despite these limitations, commercial farmers consider climate adaptation information potentially useful. Increased engagement with farmers, demonstrations and trials with farmers, documentation and sharing of local best practices will be some of the key steps towards developing more actionable knowledge for farmers' use in climate change decisionmaking.

An historical political economy analysis of high-emissions low-employment development in South Africa

Van, Doesburgh Nicholas 30 July 2023 (has links) (PDF)
South Africa is grappling with persistently high levels of poverty, inequality and unemployment, while at the same time being one of the top twenty greenhouse gas emitters in the world. While calls have been made for South Africa to embark on a just transition to a lowcarbon society, a better understanding is needed of the factors that have led to the country's current unsustainability. Drawing on the concept of the minerals-energy complex, this thesis presents an historical political economy analysis of South Africa's industrialisation process in order to (1) identify the key factors that have contributed to the country's high emissions and low employment; and (2) to determine the role of industrial policy in shaping this unsustainable development pathway. The analysis shows that the capital- and energy-intensive characteristics of South Africa's industrial structure have contributed to the country's high unemployment and high emissions. While industrial policy has been instrumental in shaping this industrial structure, its role in the post-apartheid era has been complicated by the existence of a ‘hidden' industrial policy in conflict with official objectives as well as implementation challenges which together have constrained the effectiveness of policies aimed at inclusive decarbonisation. From these results, it is argued that the adoption of an integrated green industrial policy has an important role to play in enabling South Africa to embark on a just transition to an inclusive low-carbon society.

The role of local government in the implementation of Sustainable Development Goals : A case of Tshwane Municipality

Nkhabu, Malilomo Francisca 07 1900 (has links)
The new sustainable development agenda for 2030 was adopted in 2015 with implementation now in progress. This ambitious agenda proposed 17 goals and 169 targets in areas of significance: people, planet, prosperity, peace and partnership. Goal 11 of the 17 Goals strive to ‘make cities and human settlements inclusive, safe, resilient and sustainable’. With people continuously choosing to live and work in cities despite the congestion and pollution that result from the high concentration of people, due to the economic growth, innovation and opportunities offered by cities. Hence, it is important to acknowledge that without well-managed urban transition the success of the SDGs will be difficult in developing countries. In the context of this research, it was important and applicable to look at how the ambitious global agenda like the Sustainable Development Goals (SDGs), more specifically Goal 11 on cities is being implemented by local government for cities. The research focus on City of Tshwane Metropolitan Municipality (CTMM) as a case study for implementing SDG 11. The appropriate research methodology, based on an interpretivist paradigm coupled with the phenomenological constructivism nature of this research, is qualitative. The goal was to combine document analysis and semi-structured interviews to provide the researcher with a more complex understanding of the role of local government, and thereby help the researcher answer the research questions. The research shows that the national, provincial, and local priorities in policy and programmes in South Africa have a high overlap with the SDGs. It is well recognized that development in South Africa can only take place through collaboration between citizens and government, thus policies and their implementation will have to recognize the importance of collaboration. Strategic partnerships between different sectors; government, private sector, civil society and international organisations will bring a strong blend to different strengths and has proved to have means for knowledge sharing. Thus, for CTMM to reach its goal of adequately implementing SDG 11 they would have to leverage on strategic partnerships, develop a framework for implementation and monitoring progress as a way of focusing on implementing the objectives of the Urban Goal while ensuring that there is integration between its national agenda and the global goals. / Mini Dissertation (MA (Environment and Society))--University of Pretoria, 2021. / Geography, Geoinformatics and Meteorology / MA (Environment and Society) / Unrestricted

A Multi-objective Decision-Making Framework for Sustainable Urban Development

Nasef, Khaled January 2017 (has links)
Planning in the context of urban sustainability is very challenging as it requires simultaneous integration of a large number of conflicting objectives pertaining to economic, environmental and social dimensions. It also involves multiple stakeholders with opposing views, and a high level of uncertainty. In addition, the process should be transparent, participatory and understandable by all participants. Existing literature has called for exploring new analytical methods to support decision-making for urban sustainability. This research introduces a structured decision support framework underpinned by Multi-objective Decision-Making (MODM) and Multi-attribute Decision Making (MADM). The framework provides systematic guidance to decision-making starting from problem structuring to generating a wide range of alternatives until the selection of the final solution. The developed framework is tested in two different decision-making situations pertaining to real urban problems. In the first case study, the framework is examined in the situation where the decision-maker is available to interact with the planner at the design stage. The framework is used to find a sustainable distribution of healthcare centers taking into consideration conflicting objectives including cost, efficiency of service and accessibility. The optimal solution is reached through an interactive process with stakeholders. In the second case study, the framework is examined in the situation where the decision-maker is unavailable for interaction at the design stage. The framework is used to develop planning scenarios for transit-oriented development (TOD) around a transit station. The optimal intensification of land use and land use mix is achieved taking into consideration the conflicting objectives of various stakeholders. Large number of non-dominated alternative solutions has been generated. An interactive tool has been developed by which the stakeholders can identify the alternative that best reflects their preference. The quality of the outputs for both case studies has shown that the developed planning methodology outperforms conventional approaches. The developed framework has proved to be a flexible and practical approach to assist decision-making in the context of urban sustainability / Dissertation / Doctor of Philosophy (PhD) / Achieving sustainable urban development is a very challenging task for planners.

It also involves multiple stakeholders with opposing views, and a high level of uncertainty. In addition, the decision-making process should be transparent, participatory and understandable by all participants. This research introduces a decision-support framework, underpinned by mathematical modeling techniques, to assist in achieving sustainable solutions for urban development problems. The framework is examined through two case studies.

Agroindústria Canavieira: Uma Análise Sobre o Uso da Água na Produção Sucroalcooleira

Alves Pereira, Bruno January 2009 (has links)
The relation between water and sugarcane is a topic that has been greatly discussed, but on which there are few theoretical writings. To try to help with the small existing literature, this work presents a series of four studies. The first study researches the beginnings of the activity of sugarcane in Brazil and its dependence on water resources, for, without water, the plant could not live, neither the wheels of the royal mills, the first units of sugar production in the country, moved byhydraulic power, could work. The second study describes the effects of changes in the industrial production system of sugarcane by-products on the banks of the rivers where the first plants were installed, which followed the trends of the Industrial Revolution. The third study examines the technical changes that took place in the agricultural techniques of the sugarcane agribusiness as a result of the industrialization of agriculture, and its impacts on the bodies of water. The fourth study discusses the problems related to water availability and water use by the sugarcane agribusiness in São Paulo, currently the largest State producer of sugarcane and its by-products in Brazil. The objective of the work is to study the way in which water resources are being used by the sugarcane agribusiness over the years and to evaluate the quality of the relationship between water and sugarcane. The conclusion of the study indicates that water is being used carelesly by the sector, being consumed excessively in the stages of industrial processes and contaminated by effluents and agricultural waste.

Extra-curricular education for sustainable development interventions in higher education

Lipscombe, Bryan Paul January 2009 (has links)
Universities are seen to have a central role in the UN Decade of Education for Sustainable Development (ESD), partly through their teaching and research activities. However, the critique of Higher Education's (HE) contribution to sustainable development thus far points to the limitations of a discipline driven, curriculum content and solely student focused response. Within this context, extra-curricular interventions, for example, running awareness campaigns, creating groups and organising events, appear to have potential to advance ESD in HE. However, there has been little investigation or published work in this area. Ideas of non formal and informal education; constructivist theories of learning; concepts of free choice, tacit and social learning, and the notions of whole systems thinking and sustainable education all point to roles for interventions in the extra-curricular sphere. This thesis explores the use of extra-curricular interventions in HE through an empirical investigation in the UK. A 2006 postal survey of Higher Education Institutions (HEIs) records the extent and type of interventions in use and opinions about their utility. A case study, developed through action research, reports the use and impact of extra-curricular ESD-related interventions at one HEI over an academic year (2006-07). In this case study, regular contact with a group of staff and students over the year is used to map changes in their thoughts and actions relating to sustainable development, and to record the influences attributed to these changes. Importantly, extra-curricular ESD-related interventions are found to be commonly used in UK HE, and to have a prominent position in ESD work despite their limited visibility in the literature. Their utility is confirmed as they are seen to provide experiences that contribute to student and staff learning, as well as institutional change. The evidence collected supports their roles as: disciplinary bridge', community bridge; socialisation scaffold, and social learning arena. They appear to have a useful developmental role in mobilising and motivating members of the campus community. As peripheral activities, however, extra-curricular interventions may be prone to erratic implementation through being under-resourced. They can extend participation in BSD although will not reach everyone. They are best viewed as a complementary part of BSD and linked to a process of curricular and pedagogic renewal. In addition to confirming the extent, utility and limitations of extra-curricular ESD practice, the research contributes a model to map understandings of sustainable development. This model points to a core environmental understanding to which extra layers and strands of thinking can be added. It also confirms the importance of non formal and informal influences in shaping people's conceptions of sustainable development.

Are there inherent contradictions in attempting to implement education for sustainable development in schools?

Vare, Paul January 2014 (has links)
Despite being ranked according to narrow measures of pupil achievement, many schools aim to become more sustainable. Faced with indicators suggesting the rapid degradation of social-ecological systems, these schools would prefer not to be part of the problem. However, environmental education/education for sustainable development (EE/ESD) in schools does not reflect the transformative rhetoric of academic discourse. Research into this ‘rhetoric-reality gap’ has focused either on academic discourse or the psychology of individual teachers; there is a lack of critical research on teachers-in-context. This enquiry explores the notion of inherent contradictions in developing a sustainable school (however subjects define this). It applies an Activity Theory framework designed to identify contradictions within ‘activity systems’ (e.g. schools). The primary method is a semi-structured interview conducted with fifteen teachers/headteachers in twelve schools (primary and secondary). The thesis offers a resource-efficient qualitative interview process that can bring Activity Theory to school-based research with minimum disruption and outlines a streamlined process of dilemma analysis. The data highlights contradictions in the way that schools conduct EE/ESD noting that these are often not recognised by educators themselves. Five different responses to contradictions are identified, including ‘expansive learning’ that redefines the activity itself. In terms of an ESD1/ESD2 framework, this might be termed ‘ESD 3’. Four approaches that schools may adopt in relation to sustainability are also outlined. An empowering vision of schools – and society – as autopoietic systems, i.e. as both products and producers, suggests that social reality is not as inevitable as it seems. By confronting contradictions, educators demonstrate the adaptive capacity required by young people if they are to engage in remodelling their world. Finally, the thesis proposes combining a two-sided conception of ESD with Activity Theory, potentially to the mutual benefit of both. Investigating this further is one of a number of options for further research.
