Policy, planning and provision : a case study of water in the Limpopo Province.Mdanisi, Charlotte Tshikani. January 2010 (has links)
The purpose of this study was to explore and understand how policies and legislative frameworks impact on the planning for water provision in rural areas, and in particular, the Makosha village in the Mopani District Municipality, Limpopo Province. The research method used was qualitative, which is exploratory, descriptive and conceptual in nature. The sample selection method was purposive since it was targeting specific people. Data were collected from a focus group and individuals through in-depth interviews. The findings of the study for the focus group were presented under the following themes:- Problems related to water provision; problems related to rights; communication between the municipality and the community; and respondents’ envisaged recommendations related to problems of water supply. The findings for the individual interviews were also presented under the following themes: - The district municipality’s expression of its difficulties when providing water; and planning. The results of the study provide evidence that water provision in rural areas is still a challenge. Mopani District municipality does not have the capacity to provide water. Water sources in the Greater Giyani municipality are not able to provide water to the various villages due to inadequate infrastructure. In the Makosha village, technical challenges are a cause of the problem. Illegal connections, lack of public participation in water provisioning activities and lack of skills in water provision were also identified as a cause of the problem. It is noted that the use of the Water Service Development Plan (WSDP) and the Integrated Development Plan (IDP), as planning tools, were not properly implemented. The study recommends that planning for water provision should be in line with the various legislative frameworks put in place in the country. The two planning tools, i.e. Water Service Development Plan (WSDP) and Integrated Development Plan (IDP) must be used in planning for water provision in all municipalities which are either a water service authority (WSA) or a water service provider (WSP). The capacity of the municipality should be improved in terms of skilled human resources, financial resources and infrastructural development. The Water Services and local government sectors should create a culture of public participation in the activities of the municipality. Monitoring and Evaluation should form an integral part of project implementation. / Thesis (M.Com.)-University of KwaZulu-Natal, Westville, 2010.

From words to action : Lessons from active stakeholder participation in water managementFranzén, Frida January 2015 (has links)
Water governance worldwide is going through a shift towards more holistic and participatory approaches. In Europe, the EU Water Framework Directive (WFD) adopted in 2000, aims at protecting surface water and groundwater. The WFD emphasizes the importance of stakeholder participation in planning and implementation of the directive, and in order to reach environmental objectives. However, the empirical findings are insufficient regarding how stakeholder participation can lead to improved decisions and implemented plans. In Sweden, a major water quality problem is eutrophication caused to a large extend by diffuse nutrient leakage from agriculture. Therefore, it is important to involve farmers in water management, since their participation can lead the commitment of mitigation measures for reduced nutrient leakage. The overall aim of this study is to contribute the knowledge and understanding of active stakeholder participation in water management, in particular how it can lead to implementation of water quality objectives. The thesis addresses stakeholder participation in eutrophication management in local Swedish catchments, with a particular focus on farmers’ participation in the commitment of mitigation measures. The results are based on case study research, involving four catchment areas in Sweden with severe eutrophication problems. The thesis identified socio-demographic factors, farmers’ knowledge, and the level of existing information and economic support for wetland creation, as factors affecting farmers’ willingness to participate in wetland creation to mitigate nutrient leakage. In the local catchment groups studied, farmers and other local stakeholders participated to discuss potential mitigation activities. In these, farmers emphasized other emitting actors’ responsibility and commitment in local action plans. Where this was realized, social capital within the group increased and led to further collaboration. The thesis also analyzed large-scale wetland programmes at catchment scale, where the organizational and institutional arrangements were central to realize farmers’ participation: inter-municipal agreements entailed sufficient resources, the organization involved the most relevant actors; and leadership resources were important. The thesis argues that organizing water management at a catchment level can be important to cope with challenges related to stake-holder participation for mitigating diffuse nutrient leakage. In particular for dissemination and collection of information, suggesting potential measures for all concerned actors, provide resources needed to realize actions, and to build trust and collaboration. The thesis also emphasized that stakeholder participation has to be underpinned by a genuine meaning, both for the initiators and the participants. / <p>QC 20150506</p>

Post- conflict peace building and natural resources: A comparative study on water management: Euphrates and Tigris River Basin in Northern and Western IraqSofi, Galawesh January 2014 (has links)
Iraq has since post conflict of 2003 administrated the Euphrates and Tigris River in accordance to the countries plan management. It is researched in this study how the Iraqi Government and the Kurdistan Regional Government have managed and prioritized its water resource comparing the Euphrates and Tigris River flowing through Western and Northern Iraq. The focus is also on approaches and the alternative consequences derived from different management perspectives. It is concluded in this study that there are different priorities and management approaches in Iraqi Government and Kurdistan Regional Government. Iraqi Government has not managed Euphrates River as needed post conflict of 2003 where the approach is not satisfactory to resolve the problem facing the Euphrates River. It can become an underlying problem to an additional distress among the population which can heighten the risk for disputes and uprising of further conflicts in the region if the problems are not solved in Western Iraq. Tigris River that is also managed by the Iraqi Government has not been the top priority and there are unsolved problems around the river. The distress amongst the population can outburst in a bad manner if problems not solved surrounding the Tigris River. However the tributaries that flow through Kurdistan Regional Government to the Tigris River are of better condition more attention is directed to water management and there are aspirations for meeting the challenges and well as changing management approach. Kurdistan Regional Government has managed to prioritize and manage water from the tributaries better than Iraqi Government.

Water strategies for Swedish sustainable urban planning : A comparison between certification systems and urban water researchSjöholm, Pia January 2013 (has links)
Sustainable development is gaining more focus than ever, and sustainable urban water management is increasingly being incorporated in urban planning worldwide. Internationally, certification systems for sustainable urban planning have gained popularity, and a Swedish version of the British certification system BREEAM Communities is on its way. In this degree project the technical water related aspects of the certification system BREEAMCommunities are analyzed and compared with the corresponding aspects of the American certification system LEED for Neighborhood Development. Water related aspects of both systems are discussed on basis of research in sustainable urban water management. Difficult questions raised in managing the urban water of the future are e.g. climate changes and new technical solutions for storm water management.

Surface Wettability Impact on Water Management in PEM Fuel CellAl Shakhshir, Saher January 2012 (has links)
Excessive water formation inside the polymer electrolyte membrane (PEM) fuel cell’s structures leads to the flooding of the cathode gas diffusion layer (GDL) and cathode gas flow channels. This results in a negative impact on water management and the overall cell performance. Liquid water generated in the cathode catalyst layer and the water moved from anode to cathode side due to electro-osmotic drag transport through the GDL to reach the gas flow field channels, where it is removed by air cathode gas stream. Due to high and uniform capillary force distribution effect of the pores through the GDL plane and surface tension between the water droplets and gas flow field channels surfaces, liquid water tends to block/fill the pores of the GDL and stick to the surface of the GDL and gas flow channels. Therefore, it is difficult to remove the trapped water in GDL structure which can lead to flood of the PEM fuel cell. The GDL surfaces are commonly treated uniformly with a hydrophobic material in order to overcome the flooding phenomena inside PEM fuel cell. Despite the importance impact of the surface wettability of both channel and GDL surface characteristics especially for the cathode side on the water management, few experimental studies have been conducted to investigate the effect of the two-phase flow in cathode gas flow channel and their crucial role. The work presented in this thesis covers contributions that provide insight, not only into the investigation of the effects of hydrophobic cathode GDL and cathode gas flow channels, on water removal, two phase flow inside the channel, and on PEM fuel cell performance, but also the superhydrophobic and superhydrophilic GDLs and gas flow channels effects. Further, the effects of a novel GDL designs with sandwich and gradient wettability with driving capillary force through GDL plane have been investigated. Two-phase flow especially in the cathode gas flow field channels of PEM fuel cell has a crucial role on water removal. Hence, in this research, ex-situ investigations of the effects of channels with different surface wettability; superhydrophobic, hydrophobic, slightly hydrophobic, and superhydrophilic on the two-phase flow characteristics have been tested and visualized at room temperature. Pressure drop measurements and two-phase flow visualization have been carried out using high speed camera. The effect of the various coating materials on graphite and GDL surface morphology, roughness, static contact angle (θ), and sliding contact angle (α) have been investigated using scanning electron microscopy (SEM), Profilometry, and sessile drop technique, respectively. It has been observed that the two-phase flow resistance is considerably affected by surface wettability of the channels. Further, the overall cell performance can be improved by superhydrophobic gas flow channels mainly at high current density over slightly hydrophobic and superhydrophilic cases tested. In addition, sandwich wettability GDL has been coated with a silica particle/ Polydimethylsiloxane (PDMS) composite. The porometric characteristics have been studied using, method of standard porosimetry (MSP). It has been found that sandwich wettability GDL has superhydrophobic surfaces with (θ = 162±2°), (α = 5±1°), and the internal pores are hydrophilic, while the mean pore radius is 7.1μm. This shows a low resistance to gas transport. On the other hand, performance testing indicates that (PEM) fuel cell equipped with sandwich wettability GDL results in the best performance compared to those with raw (non-coated) (slightly hydrophobic), PTFE coated (commercial with micro-porous layer (MPL)) (superhydrophobic), and silica coated (superhydrophilic) GDL. The wettability gradient has been introduced through plane of the one side hydrophobic GDL by coating one side of non-coated GDL with 15 wt. % of PTFE solution; however, the other side remains uncoated. The effects of wettability gradient on the water removal rate, droplet dynamics, and PEM fuel cell performance have been covered in this thesis. Water removal rate is determined using a 20 ml syringe barrel, wherein a 13 mm diameter GDL token is fixed on the barrel opening. The droplets penetrating through the GDL are visualized via a high speed camera to study the droplets’ dynamic characteristics. The GDL wettability gradient has a significant impact on water removal rate, droplets’ dynamic characteristics, and consequently enhances the overall PEM fuel cell performance.

Exploring the Implementation Potential of a Proposed Water Ethic: A Canadian Case Study into Underlying Ethical Considerations for Water Resources ManagementMatthews, Cushla January 2012 (has links)
Ideas about water use and ethics have been linked for many thousands of years. In this millennium, water resources remain a primary area of concern throughout the world, including such issues as shortages, supply, flooding, quality, restoration, allocation and regulation. Today, electronic environmental news and specialty websites contain a breadth of information on current water resources conflicts and issues
throughout the world. In many parts of the world, water quantity is decreasing and water quality is worsening, lack of access to improved water supplies is decreasing, as is access to basic sanitation. Water
challenges relating to water quantity and water quality are increasingly common in Canada and the United States due to water resources being under increasing pressure from population growth, economic activity
and intensifying competition for the water among users.
Faced with these challenges, humans are confronted with momentous decisions. Before making more decisions that will have an influence over water resources, and in response to repeated calls for a water ethic, this research takes the perspective that it is necessary to explore the ethical intentions of decision-makers with respect to water resources legislation and policy in Canada. The ultimate goal is to define a set of principles for a proposed water ethic that could and should be implemented at the municipal level of government in Canada.
A review of academic and professional literature and a mixed methods research approach comparing two case study areas was used to gain a baseline understanding of the potential influences of underlying ethical frameworks on policy makers in Calgary, Alberta and Guelph, Ontario. A proposed water ethic, containing a set of principles compiled from ethical considerations for water use in academic and professional
literature, was also developed and presented to case study participants. Participants provided feedback on their strength of agreement with each principle, thoughts on modifications, improvements and/or deletions
of any principle, and implementation considerations of the proposed water ethic at the municipal level of government.
The results indicate that case study participants in both areas apply a variety of ethical frameworks when making professional decisions about water resources management, and when preparing water legislation and policy. A review of relevant legislation, policies, documents and strategies in the case study areas supports this conclusion. In particular, components of the Consequentialist ethical framework (a perspective that can be associated with sustainable development and sustainability) are most often acknowledged in the statements of intent of the participants and water resource legislation and policies. Respondents also indicated that value positions associated with the Intrinsic Value ethical framework influenced policy preparation and decision-making; however, the ethical considerations associated with this framework are not as obvious in the language and intent of relevant legislation, plans, documents, and strategies.
The case study participants in both areas supported all six proposed principles of the proposed water ethic and offered only minor modifications to the presented wording and intent. The endorsed principles of the proposed water ethic are: (1) allocate sufficient water to maintain and enhance ecosystem integrity; (2) establish conservation and efficiency measures as a priority over new supply initiatives in water resources planning; (3) meet basic human needs and enhance equity; (4)establish open and participative decision-making processes; (5) identify and seek to obtain multiple sustainability benefits from water-centered initiatives; and, (6) explicitly acknowledge system complexity and emphasize precaution. The feedback from the participants about the proposed water ethic, in association with the results of the ethical frameworks, informed the eight implementation recommendations, including: (1) entrench a water ethic vision in
Provincial and municipal legislation; (2) work from within existing governance structures and institutional arrangements; (3) use an incremental model of decision-making; (4) provide specific policy examples for each principle within a water ethic; (5) include realistic and measurable targets within the policies; (6) accept that all
six water ethic principles are unlikely to be accepted at once; (7) ensure the overall vision of the water ethic, principles, associated examples, and measureable targets, are defensible; and, (8)acknowledge the importance of strategy. The recommendations acknowledge that while the proposed water ethic is presented as a package and each principle is valuable, conflict and trade-offs may occur during the implementation process. The recommendations are therefore pragmatic and take into account the current governance structures and institutional arrangements.
There is a growing recognition that understanding the underlying ethical perspectives that influence decision-makers may contribute to more effective water resources management legislation and policy. This research adds to this body of knowledge by showing that it is possible to identify ethical frameworks, extract the defining characteristics associated with each framework, and use case studies to suggest which ethical frameworks assert varying degrees of influence. This link between theory and practice may help organizations recognize what ethical considerations influence decision-making and identify the strengths and limitations of these ethical approaches to managing water resources. In addition, prior to this study, research had only been conducted into the identification of principles for the ethical use of water and not into the potential for implementation of a realistic and desirable water ethic that reflects sustainability and lasting well-being at the municipal level of government in Canada.
Several opportunities exist to build on this research. They include (1) investigate if the ethical intent of legislation and policy related to water resources management is put into practice, (2) identify other ethical frameworks that may apply to decision-making, (3) focus on political decision-makers and their claims and intentions about water use, (4) test the implementation of the water ethic proposed in this study, and (5) investigate how to integrate ethical considerations about water into checklists and protocols related to land use development, professional codes of conduct and standards, institutional and organizational training programs, performance measures for official plans, and as standard components for municipal council reports and ministerial presentations. This exploratory research concludes that policy makers are willing to become more aware of their underlying ethical underpinnings and to learn how ethical considerations embedded in legislation and policy have the potential to exert significant influence over the behaviour of current and future water users.
