Formulation of an integrated approach to sustainable water management in Ho Chi Minh City, Vietnam.

Vo, Phu Le January 2008 (has links)
In 1986, Vietnam opened up the country’s economy by launching the Doi Moi (renovation) policy, which made the process of economic liberalisation possible. Accordingly, Ho Chi Minh City, the country’s biggest city, has undergone rapid growth of population, urbanisation and industrialisation. While achieving remarkable economic growth, the city faces considerable urban environmental challenges. The rapid growth of urbanisation and industry has placed increasing pressure on available freshwater resources, through excessive water use and increasing volumes of untreated wastewater. Firstly, the urban water sector has had to meet growing demand for water use for domestic purposes during the dry season. Secondly, groundwater levels have experienced a substantial drawdown in outlying urban districts as a result of over-abstraction. Thirdly, rapidly expanding industrial activities are causing severe demand on water resources. The city’s major supply sources have developed an alarming level of pollutants discharged by industry. The aim of this thesis is to formulate an integrated approach to the sustainable management of water resources in Ho Chi Minh City. In order to achieve this, the research was designed to examine institutional frameworks and arrangements and to explore the perception of water value by water users and stakeholders. The underlying reasons for ineffective management are anchored in fragmented management practices which result from inadequate institutional frameworks and arrangements, inadequate regulations and inappropriate water governance. Weak enforcement of law and insufficient cooperation between government agencies and departments in Ho Chi Minh City and their counterparts in neighbouring provinces also limit management efficacy. The research results show that stakeholders have different perceptions of water resources. Overall, water value has been considered as a social and economic good by both the urban respondents and government officials. However, most urban residents view water as a social good rather than an economic one. Public involvement in the water sector is limited. Most urban dwellers have little understanding and knowledge about the city’s water issues or the available channels to access information on water resources. Many government officials are inadequately trained, poorly qualified, inexperienced and have irrelevant or outdated background knowledge about their field of management. Government respondents did not provide consistent data and information on the water profile because there is no shared common information on water issues in place. Findings from the fieldwork show that decentralisation, privatisation and using rainwater as a potential alternative water source are preferred. Finally, the study proposes a schematic revision of existing management structures and mechanisms between local government agencies. This thesis proposes a model for a water conservation strategy for which the management and use of water resources is aligned with adequate institutional arrangements and effective regulations. Water governance and management of water resources need to work with economic and urbanisation growth. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1331639 / Thesis (Ph.D.) - University of Adelaide, School of Social Sciences, 2008

Information, systems and water management : Information systems which support water management - cases from rural water supply in Uganda and WFD implementation in the North Baltic River Basin District, Sweden

Quin, Andrew January 2012 (has links)
Successfulwater management implies tackling multi-level governance and improvingintegration between sectors. Sound information and related processes will berequired to support water management decision-making at these various levels.Additionally, considering Principle 10 of the UN’s Agenda 21, actors shouldhave access to information to enable their involvement in shaping watermanagement outcomes. This thesis draws on the results of two separate caseswhere information systems support action: (i) rural water supply in Uganda;and, (ii) water management according to the Water Framework Directive in Sweden.A research approach was formed based on: (a) a model conceptualising how informationsystems support organisational processes which lead to action; and, (b) asystems-thinking methodology. The results reveal that there are numerous,similar challenges to achieving information support for action in both theUgandan and Swedish cases. In both cases, information quantity and quality islimited; consequentially, the use of information to support action is inhibited.Furthermore, not all actors are involved in information system processes; in particular,local-level actors. Overall, there is limited support of strategic decision-makingand weak support of operational, or local, decision-making. The results suggestthat it might be possible to tailor strategic-level information processes tolocal needs, hopefully encouraging active involvement of local actors. Improvedinvolvement, together with a suitable systems approach, could be used to furtherdevelop information systems, improving integration between multiple levels ofgovernance and across sectors – suiting not just the needs ofstrategic decision-making but also the needs of operational, or local,decision-making. / QC 20120822

ADAPTATION STRATEGIES TO IMPACTS OF CLIMATE CHANGE AND VARIABILITY ON TEHRAN WATER SUPPLY IN 2021 : AN APPLICATION OF A DECISION SUPPORT SYSTEM (DSS) TO COMPARE ADAPTATION STRATEGIES

Saemian, Sina January 2013 (has links)
In this thesis, the decision analysis process of investigating the best optimal strategy for Tehran water management in 2021 is described. Such process is normally divided into four steps including: structuring the problem; identifying feasible strategies, their impact and uncertainty; quantifying preferences; and evaluation of countermeasures and sensitivity analysis. Here, in order to structure the problem, the characteristics of Tehran with respect to water issues and its history of water management are reviewed. The state of surface waters and ground waters and a description of Tehran plan for waste water treatment are given, the most significant constraints of Tehran water sector are classified and the challenges of climate change and variability are explained. The feasible adaptation strategies are designed subsequently based on that classification, data extracted from a survey and a number of interviews with water officials and managers and ordinary citizens in Tehran. Each strategy contains a series of separate measures with different weights. The phase of quantifying preferences and elucidating utility functions is conducted based on the data available from previous studies and also the current survey. The measures include: installing water saving devices, awareness raising to change citizens’ water consumption pattern, adding new sources of surface water, investing on waste water utilization, migration control and repairing water distribution network.Different combinations of these measures provide different possibilities for formulating adaptation strategies. We compare two more discussed adaptation strategies of the spectrum of strategies; one is inclined toward exploiting more water resources while the other one is more focused on demand management. The former is mainly supported by water officials and the latter advocated by water experts we interviewed. The criteria of comparison are social acceptability, economic feasibility, time-efficiency and environmental tenability. By considering the uncertainty attributed to the criteria weights, the WEB-HIPRE DSS analysis shows that the demand-oriented strategy is the optimal one in most cases, however, if time-efficiency and/or economic feasibility gain very high significance, the strategy of water officials wins over that of experts.

The capacity of Montreal Lake, SK to provide safe drinking water

Lebel, Pierre Mathieu 30 April 2008
Recent waterborne disease outbreaks in Canada have brought national awareness to drinking water safety. In particular, the long history of poor water quality plaguing First Nations communities has received substantial public attention. Despite several initiatives from the federal government and considerable financial support, the quality of drinking water on reserves has shown little improvement and continues to pose health risks. As a result, there is a growing interest in the ability of First Nations communities to effectively manage their drinking water resources. The purpose of this study was to assess the capacity of Montreal Lake, SK to provide its residents with safe drinking water, both now and into the future. This research employed a mixed methods approach in the examination of the communitys water system and management practices. Data sources included individual interviews, a public workshop, documents and inspection reports, and water quality data. Water system capacity was considered in terms of financial, human resources, institutional, social/political, and technical dimensions. An analytical framework was developed through a literature review where each dimension of capacity was rated based on a series of indicators. It was determined that there are no serious deficiencies in the management of Montreal Lakes drinking water. However, a number of flaws in each aspect drinking water management were detected. These include weak linkages between the agencies responsible for drinking water provision, and a low level of drinking water safety for community residents served by the truck haul distribution system. This research confirms the multi-dimensional aspects of water system capacity, reveals the necessity for the different levels of authority to work together, and provides an analytical framework which may be applicable to future studies examining First Nations and small-scale drinking water systems.

Okanagan water systems : an historical retrospect of control, domination and change

Sam, Marlowe 11 1900 (has links)
In this study, I examine the history of colonial control, domination, and change that began in the Interior Plateau region of British Columbia in 1811 when interaction between the Syilx (Okanagan) and European explorers first occurred. I focus on water use practices in particular, employing an indigenous Syilx approach (En’owkinwixw) in order to display the negative impacts of colonial policies on the Syilx and their environment. The En’owkinwixw methodology, which calls for the incorporation of multiple perspectives, is thousands of years old, but has been modified here from its original consensus-based decision-making process. The manner in which the U.S. government developed resource and water management policies in America’s arid Far West directly influenced the models that were later adopted by British Columbia and Canada. U.S. Supreme Court decisions along with a number of international treaties and trade agreements between the United States and Canada have also compromised the ability of the Syilx to maintain a sustainable and harmonious relationship with their environment. Depression era policies in the United States led to the implementation of large-scale projects such as the damming of the Columbia River that had further negative consequences on the environment of the Interior Plateau. The Columbia River had been the destination for the world’s most prolific salmon migrations but their numbers dropped abruptly after the dams were built. In 1954, on the British Columbia side of the border, a flood-control project was completed that channelized a section of the Okanagan River that meandered between Okanagan and Skaha Lakes. Oral testimonials from Penticton elders are presented to demonstrate the severity of biological loss and give eyewitness accounts of the negative social, economic, cultural and political impacts caused by this radical alteration to the river. Evidence from four traditional knowledge keepers who continue to live near the confluence of Shingle and Shatford Creeks on the Penticton Reserve, indicates that water loss and ecological degradation in this area were caused by upstream water users outside of reserve boundaries. The study concludes with a proposal for the development of a collaborative and restorative ecological model based on application of the En’owkinwixw epistemology.

Water Management and Health in Ghana : Caes Study - Kumasi

Aakumiah, Prince Osei January 2007 (has links)
There have been multiple cases of drinking water related diseases in Ghana, particularly the cities. Kumasi, the second largest city is recording high figures of drinking water related diseases. The Ghana water and sewage company is supposed to provide adequate safe drinking water to the people. However, the company has failed to provide this service effectively. Various reasons have been given by the company on its inability to perform efficiently. Meanwhile the government decided lately to privatise water in the cities to facilitate access to quality water through what is called “FULL COST RECOVERY”. This attracted a lot of international companies to Ghana but this has also generated protest and demonstrations. The argument is that these foreign companies are basically profit oriented and considering the fact that most of the affected people are very poor, suggesting they cannot afford it. The study is aimed at finding out the relationship between water management and health in the study area and how effective water management through full community participation could help provide adequate safe drinking water. The study was a non-interventional descriptive type using both qualitative and quantitative methods. It was conducted in Kumasi, the second largest city in Ghana. A total of 100 residents from the communities was selected through systematic sampling and interviewed. This includes 86 local residents and 14 key informer interviews. The study also relied on observation as well as some selected literature. The results confirmed that drinking water related diseases is on the increase with the most affected people being the poor living in shanty and informal areas of the city. It was also found that most people in the city are willing to render any services to provide safe drinking water. But in relative terms, most of these people are very poor with high percentage of illiterates and may only contribute if there is a good relation and trust among all. It however appears that community participation is a good option for the city provided that stakeholders are made to play effective roles.

Implementing the soft path approach to water management: A case study of southern York Region, Ontario

Patch, William January 2010 (has links)
This research study develops a framework of indicators to evaluate the ‘institutional capacity’ of a municipality to implement the soft path approach. The soft path approach is a new strategy for water conservation that complements existing supply and demand water management regimes. The soft path approach aims to achieve sustainability by changing how individuals think about water and how water is used. The framework of indicators consists of qualitative descriptions of elements that should be present in a municipality to successfully implement the soft path approach. These indicators fit into eight themes: human resources, information resources, financial resources, policy and legal environment, political environment, community awareness and involvement, technological solutions, and practical considerations. These indicators are also applied to evaluate the institutional capacity of a case study (southern York Region, Ontario, Canada) for its potential to implement the soft path approach. The case study is compatible and equipped to implement the soft path approach, but this can only be accomplished if coordinated with other levels of government and external organizations.

The Influence of Stakeholder Values on the Acceptance of Water Reallocation Policy in Southern Alberta

Parrack, Cameron 06 December 2010 (has links)
Historically, a great deal of water has been allocated to the agricultural sector in Alberta to support economic development and to contribute to food security. However, demand from other areas has increased in recent years, notably from the environment. Meeting new demands while still satisfying existing users has become a significant challenge. The combination of increased water use efficiency and productivity combined with reallocating water from agriculture to other sectors has emerged globally as a solution to this challenge. Thus, new policies regarding water reallocation need to be developed. Designing policies that are acceptable to the various stakeholders involved poses a considerable challenge. The values held by individuals determine how they will react to new public policies. Hence, to support effective policy making, a better understanding of how the non-irrigator population perceives water reallocation issues is necessary. Using mail-out surveys to collect data from the populations of Lethbridge, Alberta, and the surrounding smaller communities, this research aimed to identify the values regarding water allocation held by domestic, non-irrigator water users, and to determine how these values influence their acceptance of water allocation policies. Findings from the survey reveal how non-irrigators’ values influence their opinion of water transfers from the irrigation sector to the urban and environment sectors, and the conditions under which they should take place. A pro-environment value orientation was most prominent amongst the urban sample, while the rural sample was mainly moderate in their value orientation. The large moderate value cluster within the rural sample represented both pro-economic and pro-environment values depending on the focus of the survey item. Statements that would affect the community (irrigation sector) were met with pro-economic values while statements that involved making a personal sacrifice in order to protect the aquatic environment were strongly supported. Value orientation was found to greatly influence the respondents’ perception of water reallocation policy.
