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

Abstract

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.
