Water Resources Vulnerability

Climate change impact on water resources has been a global hot issue in recent years. In accordance with the latest research progress, a new meaning of water resources vulnerability (WRV) and a concept of adaptive water management have been proposed. For evaluating WRV under the changing environment in the Huai River Basin (HRB), the sixth largest river basin in China, a quantitative assessment model coupling with exposure, droughts risk, sensitivity, and adaptability of water resources system was established. In addition, the adaptive regulation of WRV under five scenarios of water demand control, water efficiency control, pollutant restriction of the water function zone, the minimum water demand control of the ecosystem and integrated control were analyzed in this study. The results indicated that the region with the greatest value of WRV was Xiaoqing River in the benchmark year (2000) and the most unfavorable scenarios in which 33% and 87% of HRB were the extreme vulnerable regions. Among all adaptive regulation scenarios, the most sensitive scenario was the integrated control, followed by the control of water function zone compliance, water use efficiency, water demand and the minimum water demand control of the ecosystem. This study will provide a scientific foundation to integrated water resources management in China.

Abstract The relationship between water abstraction and water availability has turned into a major stress factor in the urban exploitation of water resources. The situation is expected to be sharpened in the future due to the intensity of extreme meteorological phenomena, and socio-economic changes affecting water demand. In the city of Volos, Greece, the number of water counters has been tripled during the last four decades. This study attempts to simulate the city's network, supply system and water demand through a forecasting model. The forecast was examined under several situations, based on climate change and socio-economic observations of the city, using meteorological, water pricing, users' income, level of education, family members, floor and residence size variables. The most interesting outputs are: (a) the impact of each variable in the water consumption and (b) water balance under four management scenarios, indicating the future water management conditions of the broader area, including demand and supply management. The results proved that rational water management can lead to remarkable water conservation. The simulation of real scenarios and future situations in the city's water demand and balance, is the innovative element of the study, making it capable of supporting the local water utility.

Abstract China is actively exploring water resources management considering ecological priorities. The Shaying River Basin (Henan Section) serves as an important grain production base in China. However, conflicts for water between humans and the environment are becoming increasingly prominent. The present study analyzed the optimal allocation of water while considering ecological priorities in the Shaying River Basin (Henan Section). The ecological water demand was calculated by the Tennant and the representative station methods; then, based on the predicted water supply and demand in 2030, an optimal allocation model was established, giving priority to meeting ecological objectives while including social and comprehensive economic benefit objectives. After solving the model, the optimal results of three established schemes were obtained. This revealed that scheme 1 and scheme 2 failed to satisfy the water demand of the study area in 2030 by only the current conditions and strengthening water conservation, respectively. Scheme 3 was the best scheme, which could balance the water supply and demand by adding new water supply based on strengthening water conservation and maximizing the benefits. Therefore, the actual water allocation in 2030 is forecast to be 7.514 billion (7.514 × 109) m3. This study could help basin water management departments deal with water use and supply.

Water Resources Vulnerability

The vulnerability of water resources is an important criterion for evaluating the carrying capacity of water resources systems under the influence of climate change and human activities. Moreover, assessment and prediction of river basins’ water resources vulnerability are important means to assess the water resources security state of river basins and identify possible problems in future water resources systems. Based on the constructed indicator system of water resources vulnerability assessment in Song-Liao River Basin, this paper uses the neighborhood rough set (abbreviated as NRS) method to reduce the dimensionality of the original indicator system to remove redundant attributes. Then, assessment indicators’ standard values after dimensionality reduction are taken as the evaluation sample, and the random forest regression (abbreviated as RF) model is used to assess the water resources vulnerability of the river basin. Finally, based on data under three different future climate and socio-economic scenarios, scenario predictions are made on the vulnerability of future water resources. The results show that the overall water resources vulnerability of the Song-Liao River Basin has not improved significantly in the past 18 years, and the overall vulnerability of the Song-Liao River Basin is in the level V of moderate to high vulnerability. In the future scenario 1, the overall water resources vulnerability of the river basin will improve, and it is expected to achieve an improvement to the level III of moderate to low vulnerability. At the same time, the natural vulnerability and vulnerability of carrying capacity will increase significantly in the future, and the man-made vulnerability will increase slowly, which will deteriorate to the level V of moderate to high vulnerability under Scenario 3. Therefore, taking active measures can significantly reduce the vulnerability of nature and carrying capacity, but man-made vulnerability will become a bottleneck restricting the fragility of the overall water resources of the river basin in the future.

Projections indicate that the Mediterranean region is an area where drastic changes in climate will occur, which will significantly affect water resources. In a context of increasing pressure on water resources as a result of the reduction in water availability, it is essential and urgent to structure water management in a way that allows for adaptation to the challenges that the changing climate will bring to an already water scarce region. It is necessary to generate experiences and methodologies that are based on real case studies that will lay the foundations for the generalisation of practices of climate change adaptation in water management. In this study, we have developed a ready to use analytical framework to evaluate the coherence of water management plans and programs with climate change adaptation principles. We have tested the applicability of the framework that was developed on the Tordera River Basin Adaptation Plan (TRBAP). The analytical framework has proven to be easy to apply and to allow for identifying the inclusion or exclusion of key climate change adaptation features appropriately. We have structured this analytical framework as a starting point contributing to further assessments of how climate change adaptation is incorporated in water management.

Nowadays, ecological problems are being caused by economic aspects, and other hand economic issues are arising from ecological and environmental problems. Therefore, it is important to consider both social and economic factors, and take a basin approach to solving environmental problems. To find a relationship between economy and ecology, complex study of river basins is extremely important in establishing conditions for sustainable development in our country. This paper shows the results of applying DPSIR (Driver-Pressure-State-Impact-Response) analysis for Ulaanbaatar city, undertaken as part of a project on Integrated Water Management for the Selenge River Basin. The DPSIR analysis looks at the linkage between the economy and environment for the water quality and water resources of Ulaanbaatar. We used mDSS4 software to evaluate a range of management responses suggested by these issues and found that charging for pollution and measuring water use would have the largest overall impact on water quality and water resources respectively. The analysis was carried out for Ulaanbaatar, because it was identified as one of the key hotspot areas in the Selenge River Basin, which is the main river basin in Mongolia, in terms of both the economy and natural systems.DOI: http://dx.doi.org/10.5564/pmas.v0i4.43Proceedings of the Mongolian Academy of Sciences 2009 No 4 pp.22-31

Abstract Since 2011, China has implemented its most stringent water management system to effectively protect water resources and guarantee socioeconomic development. More basin-scale water division schemes have been developed to act as references for basin-scale water resources management. Water dispatching during dry periods is an effective way to guarantee the water supply for the river basin, and is also an important component of basin-scale water resources management. Given this, the present study proposes a framework for the water dispatching of river basins during dry periods under the most stringent water management system in China. This framework mainly consists of the analysis and forecasting of rainfall and inflow, the dispatching requirements for the main water users, major reservoirs, and sections, as well as safeguard measures. The Jian River Basin in South China is presented as a case study. The total discharge of the Gaozhou Reservoir in 2017 was 25 million m3 more than the target discharge specified in the water dispatching scheme, and the total water storage utilization ratio during the dispatch period was 4.7% higher than the target utilization ratio. These factors demonstrate the effectiveness and applicability of the proposed framework. HIGHLIGHT The proposed framework for the water dispatching of river basins during dry periods provides reliable technical support for water use security under the most stringent water management system in China, and is demonstrated to be both effective and applicable.
