Water is a resource needed in all aspects of life and is regarded as a decisive factor for Earth's ecosystems survival. However, water resource has also become a limiting factor of social and economic development. For cities of the developing world, water is increasingly playing a vital role in sustainable urban development. Since economic reform known as “Doi Moi" (renovation) in 1986, Ho Chi Minh City, Vietnam, has undergone the rapid growth of urbanization and industrialization. As a result, the City has experie critical environmental challenges in which water use and management have placed constraints on its sustainable development. These striking challenges include water shortage, pollution and depletion of surface and groundwater sources. The underlying reasons can be attributed to inadequate management practices. The purpose of this paper is to provide an overview of rapid urbanization and growing water resource problems. It also examines the management practices and analyze the root causes of water resource issues in the course of sustainable development.

Model Framework

Predicting and allocating water resources have become important tasks in water resource management. System dynamics and optimal planning models are widely applied to solve individual problems, but are seldom combined in studies. In this work, we developed a framework involving a system dynamics-multiple objective optimization (SD-MOO) model, which integrated the functions of simulation, policy control, and water allocation, and applied it to a case study of water management in Jiaxing, China to demonstrate the modeling. The predicted results of the case study showed that water shortage would not occur at a high-inflow level during 2018–2035 but would appear at mid- and low-inflow levels in 2025 and 2022, respectively. After we made dynamic adjustments to water use efficiency, economic growth, population growth, and water resource utilization, the predicted water shortage rates decreased by approximately 69–70% at the mid- and low-inflow levels in 2025 and 2035 compared to the scenarios without any adjustment strategies. Water allocation schemes obtained from the “prediction + dynamic regulation + optimization” framework were competitive in terms of social, economic and environmental benefits and flexibly satisfied the water demands. The case study demonstrated that the SD-MOO model framework could be an effective tool in achieving sustainable water resource management.

Water is an important, but often ignored element in sustainable development by now it has been clear that urgent action is needed to avoid global water crisis. Water resource management is the activity of planning, developing, distributing and managing the optimum use of water resources. Successful management of water resources requires accurate knowledge of their resource distribution to meet up the competing demands and mechanisms to make good decisions using advanced recent technologies.Towards evolving comprehensive management plan in suitable conservation and utilization of water resources space technology plays a crucial role in managing country’s available water resources. Systematic approaches involving judicious combination of conventional server side scripting programming and remote sensing techniques pave way for achieving optimum planning and operational of water resources projects.   new methodologies and 24/7 accessible system need to be built, these by reducing the dependency on complex infrastructure an specialist domain Open source web GIS systems have proven their rich in application of server side scripting and easy to use client application tools. Present study and implementation aims to provide wizard based or easily driven tools online for command area management practices. In this large endeavour modules for handling remote sensing data, online raster processing, statistics and indices generation will be developed.

Set Up

Participatory water resource management assumes great significance in the changing context of fresh water availability and use. The forces of market economy, in most cases, have transformed the rural social scenario in such a way that community participation in resource management has become almost a far cry. But the Himalayan foothill area in Assam sets a good example of management and sharing of water resources by the communities living in the area in eco-friendly and socially just ways. This study is an attempt to analyse the traditional management practices called dong-bandh system evolved by the local people to harvest and share the stream water for agricultural and domestic purposes. Based on data collected from secondary sources and generated through primary survey, the study focuses on the organizational set-up of the community participation, water distribution policies, conflict resolution and perception of the people on dong–bandh governance. The challenges faced by this traditional system during the recent period have also been discussed.

The goal of this paper is to identify the major outlines of innovative, integrated and decentralized water management practices, training, research, and development needs in various aspects of soft path water resource management in developing countries of Asia. The decentralized water strategies including science, regulations, training, government policies, and funding for some of the developing countries in Asian region are reviewed. There are two primary ways or paths of meeting water-related needs; one the “hard” path, and the other “soft” path that complements mainly decentralized and open decision-making, application of efficient technology, and environmental protection. One of the soft path decentralized solution being implemented in many developing countries of Asia is small scale rainwater harvesting and management and both government and non-government sectors are promoting the practice on a regional community and family basis. Overall, the paper aims to contribute to the ongoing development of environmentally sound and economically viable approaches to water management in the developing world.

Descriptive Survey

Water is one of the basic needs of human beings and is imperative for sustaining the quality of life on earth (Brooks, 2006).  However, its unbalanced and unmanaged use makes its scarce. Hence, this study assessed the water resource management practices of the 53 food establishments in Siquijor Province. The study utilized the descriptive survey using a self- made questionnaire which yielded that majority of the respondents are females and are in the age brackets of 18-40 and 41-62. A greater majority of the establishments were in the operation for more than ten years. As to respondents’ water resource management practices, they Often do not let water flow while cleaning or rinsing, check the water supply system for leaks and turn off unnecessary flows, and adjust water flow by the type of cleaning to be undertaken, but they Never install self-closing faucets. However, reading water meter regularly, washing only full loads in the dishwasher, and installing low flush toilets were sometimes done while installing automatic water volume controls, reusing the rinse water from the dishwasher and installing flow regulators on the faucet heads were seldom practiced. The respondents’ sex, age and number of years in operating the business had no significant relationships to their extent of water resource management practices. Thus, it is concluded that better management coupled with effective policy, awareness and efficient system is vital to enhance water resource management.

The Impact

Due to the fast growth of the economy and population, the water scarcity issue has aroused widespread critical concern. In fact, reasonable structure, adaptive patterns and effective regulation of the economy, society and water resources can bring a harmonious future. Therefore, the study of how to balance economic social growth and water resources is of great importance. A model of the water resource, society and economy system of the Tongzhou district was designed by Stella. The model established here attempts to analyze future trends in social-economic development and the impact of the economic and population growth on water use in the Tongzhou district under three scenarios. The results reveal that the water shortage is very serious. If the current trends persist, the existing water supply will not be able to meet the water demand in the future. Tongzhou district's water shortage will be 162.50 million m3 in 2020 under the business-as-usual scenario. Therefore, it is necessary to develop unconventional water sources and improve the water-saving capacity of production and life to alleviate the water tensions. This research offers insight into larger questions regarding economic growth and water resource management in general.
