The Sustainable Development

Due to the rapid development of economy, China has been facing severe water shortage and water pollution problems. This paper discusses three strategies developed for the urban water resource management in China, which is essential for the sustainable development of its economy. These strategies include setting high priority for demand control and water conservation, controlling pollution from the sources and increasing investment for wastewater treatment; and developing untraditional water resources, such as rainwater harvesting, wastewater reclamation, seawater utilization, etc. It is hoped that these strategies may not only solve the water shortage and water pollution problems at low capital and operational costs, but also meet the present and future needs on water resources in China.

Water Supply And Demand

Beijing is facing the considerable challenge of water shortage, as it is just able to meet current water demand in a year with average precipitation and a shortfall between water supply and demand is estimated to be around 1.8 billion[109] cubic meters (BCM) by 2010. Aiming to find the solution to such a severe challenge, this paper investigates Beijing's current and future water resources availability and water-use configurations, as well as past and current effort on both areas of water supply and demand. The analysis shows a continuously growing demand for water and an aggravating deficit of traditionally available water resources. The paper concludes that it is necessary to establish well-structured water-use data and employ more advanced forecasting methods if sound future decisions regarding water balance are expected to be made. In order to realize Beijing Municipality's full urban water conservation potential, it is suggested that a comprehensive and integrated long-term conservation program be implemented, which is technically feasible and economically justified, to conserve water consistently for many years.

Urban Water Management

Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The Urban-Water Harmony (UWH) model is based on the concept of harmony and offers a more integrated approach to urban water management. This model calculates four dimensions, namely urban development, urban water services, water–society coordination, and water environment coordination. And the Analytic Hierarchy Process has been used to determine the indices weights. We applied the UWH model to Beijing, China for an 11-year assessment. Our findings show that, despite the severe stress inherent in rapid development and water shortage, the urban water relationship of Beijing is generally evolving in a positive way. The social–economic factors such as the water recycling technologies contribute a lot to this change. The UWH evaluation can provide a reasonable analysis approach to combine various urban and water indices to produce an integrated and comparable evaluation index. This, in turn, enables more effective water management in decision-making processes.

Water Treatment Cost

Rainwater harvesting from roof is considered as valuable water resources. Material Flow Analysis (MFA) of water in Mahasarakham University (Khamriang Campus) shows that rainwater harvesting from roof can reduce water supply production by 7% and save more than 200,000 Bt/year for water treatment cost. The sensitivity analysis suggests that by 5% water supply conservation and 20% additional rainwater harvesting, MSU could have enough water resources. The rainwater is suitable to be substituted water for gardening due to the convenience to assemble an above ground storage tank or a pond to store harvested rainwater from roof. The current practice of rainwater is collected and discharged into drainage system and treated in wastewater treatment plant. Utilisation of rainwater harvested could reduce wastewater amount that must be treated by 9%. Rainwater harvesting and reuse should be promoted in campus in order to encourage sustainable living and water conservation policy.

The Cost

Wastewater reclamation and reuse are becoming important components of the management of urban, regional and national water resources. Recently, not only countries with chronic water shortage, but also urban areas in temperate climates have considered and implemented wastewater reuse schemes expanding the scope of consumptive uses to include toilet flushing and landscape irrigation, using dual distribution systems and even the reuse as potable waters is being considered and evaluated. Israel is an example of intensive reuse in agricultural irrigation and much experience has been gained in treatment, seasonal reservoirs and establishing quality requirements. The economical justification of wastewater reuse schemes should take into account the overall treatment costs, the ‘environmental and health allowances', i.e. the cost of treatment required even when reuse is not practiced, the benefits of water and the savings in conveyance and pumping. The paper also briefly describes the two largest wastewater reclamation projects in Israel, namely: the Kishon Complex Scheme and the Dan Region Scheme, both aimed at unrestricted agricultural irrigation of all crops.

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.

The Relationship

This article intends to summarize the findings of studies on the relationship between farmers’ behavioral intentions (BI) and water-conservation behavior (WCB) using the theory of planned behavior (TPB). A systematic review of transcripts obtained from Internet-based searching on reliable scientific databases (e.g., SID, ProQuest, Springer, Science Direct, John Wiley, Sage, Taylor & Francis, Emerald Insight, and Google Scholar) was followed by outfitting data for the Comprehensive Meta-Analysis (CMA) software. Data from a total of 28 studies on WCB were synthesized and analyzed through the CMA procedure. The resulting evidence demonstrates that the total and summarized estimate point (i.e., correlation) for the associations of attitude (ATT), subjective norms (SNs), and perceived behavioral control (PBC) with BI was 0.46, 0.36, and 0.26, respectively (r(t)PBC < r(t) SNs < r(t)ATT → BI). Furthermore, the effect size of the relationship between PBC and WCB was 0.27. The largest effect size pertained to the relationship between BI and WCB (BI → WCB) (r(t)BI = 0.52). The take-home message of the article is that hypothetical statements of the TPB are confirmed, as would be hypothesized. These findings should still be regarded in the field of WCB research; thus, policymakers need to provide solutions and adapt their policy initiatives for water resource management based on these findings. For example, one of the solutions to improve water resource management based on the research results is to examine the views and realities constructed by farmers of water resources and related management styles before carrying out water resource management projects. Identifying the potential capabilities of farmers and their economic and social background to expand water-conservation behavior and the tendency and acceptance of water resource management project to be implemented is also an important requirement in making resource management projects effective. The use of various methods of the individual, group, and collective communication to interact with farmers combined with provision of extension training, as well as mobilizing and organizing farmers to facilitate effective management of water resources are recommended.

Although the annual precipitation in Korea is 30% higher than the world average, increased population, urbanization and industrialization, as well as improved living standard have caused problems such as water shortage, flood damage, and water pollution. Additional multi-purpose dams and infra-structures are supposed to be constructed by 2011. On the other hand, water demand control is also suggested. This includes water saving by increasing water price, reuse of treated water, development of new water resources and rainfall management. Beside the Comprehensive Measures on the Provision of Clean Water, Comprehensive Water Quality Management Measures for the Four Major Rivers and Act on Watershed Management and Community Support are the main policies to be implemented for improving the quality of major rivers. Recently, Total Water Pollution Load management is voluntarily pursued for sustainable management of water resources.
