The Impact

As water security becomes an increasingly important issue, the analysis of the conflict between water supply and demand has gained significance in China. This paper details a bibliometric review of papers published between 2003 and 2018 on the water footprint in China, one of the global hotspots of water resource research. The tendencies and key points of water footprint research were systematically analyzed based on 1564 articles, comprising 1170 original publications in Chinese from the China National Knowledge Infrastructure database and 394 publications in English from the Web of Science database. The results show that the literature associated with water footprint research has expanded significantly. The number of papers published increased from 104 in 2003–2006 to 735 in 2015–2018. Water footprint research has been applied to agricultural, industrial, and regional water resource management to quantify the impact of human activities on water resources and the environment. Water footprint metrics were extracted for regional comparisons. There are obvious regional characteristics of the water footprint in China, but the uncertainty of results makes further investigation necessary. Further water footprint modeling and field experimental research is needed to explore the water–ecological environment under complex systems.

Agricultural Demand

There are three chasms that block the route to water security: the impact of population growth (and the associated urbanization); widespread malnutrition and poverty; conflict between agricultural demand and other human uses of water. To cross these chasms requires firstly education (primary education for girls is crucial) and the introduction of integrated water resource management. It requires the application of community energies and dedication, and the harnessing of private sector energies resources, but it will also need the development of innovative financial mechanisms. Above all it requires a major shift in the way we manage water, discarding prejudices and preconceptions, to address our water needs with imagination and commitment.

For countries in Southeast Asia that mainly rely on surface water as their water resource, changes in weather patterns and hydrological systems due to climate change will cause severely decreased water resource availability. Warm weather triggers more water use and exacerbates the extraction of water resources, which will change the operation patterns of water usage and increase demand, resulting in water scarcity. The occurrence of prolonged drought upsets the balance between water supply and demand, significantly increasing the vulnerability of regions to damaging impacts. The objectives of this study are to identify trends and determine the impacts of extreme drought events on water levels for the major important water dams in the northern part of Borneo, and to assess the risk of water insecurity for the dams. In this context, remote sensing images are used to determine the degree of risk of water insecurity in the regions. Statistical methods are used in the analysis of daily water levels and rainfall data. The findings show that water levels in dams on the North and Northeast Coasts of Borneo are greatly affected by the extreme drought climate caused by the Northeast Monsoon, with mild to the high risk recorded in terms of water insecurity, with only two of the water dams being water-secure. This study shows how climate change has affected water availability throughout the regions.

Growing populations, socio-economic development, the pollution of rivers, and the withdrawal of fresh water are all signs of increasing water scarcity, and with 85% of global use, agriculture is the biggest freshwater user. The water footprint (WF) and virtual water (VW) are concepts used recently for freshwater resources assessment. The WF reflects how much, when and where the water was used whereas VW reveals the volume of water embedded in goods when traded. The first goal of this research is to determine the WF per ton and the WF of production (Mm3/yr) of wheat, barley, rice, and maize in Iraq. The second goal is estimating the quantities of the 4 main cereal crops imported into Iraq and assessing the impact on reducing WF and land savings for 10 years from 2007 to 2016. The results showed that the WF per ton was 1736, 1769, 3694, 2238 m3/ton and the WF of production was 5271, 1475, 997, 820 Mm3/yr for wheat, barley, rice, and maize, respectively. The median total VW imported was 4408 Mm3/yr, the largest volume was 3478 Mm3/yr from wheat, and Iraq saved about 2676 Mm3 of irrigated water and 1,239,539 M ha of land by importing crops every year during 2007–2016. The study revealed the significance of better irrigation management methods to decrease the WF through a selection of crops that need less water and cultivation in rain-fed areas, as well as the use of cereal import to conserve scarce water resources, which is crucial both in terms of water resource management and preservation of the environment. The results of this research could be used as a guideline for better water management practices in Iraq and can provide helpful data for both stakeholders and policymakers.

Daunting Task

Abstract Dhaka the capital of Bangladesh is facing a serious water scarcity problem due to the big gap between demand and supply of water system. When accelerating water scarcities and pollution in and around urban centers are superimposed on issues like continuing urbanization, lack of investment funds for constructing and maintaining water infrastructures, high public debts, inefficient resources allocation processes, inadequate management capacities, poor governance, inappropriate institutional frameworks and inadequate legal and regulatory regimes, water management in the megacities poses a daunting task in the future. To overcome these water related problems, water can be a designing element for structuring future development with the combination of sustainable approaches for social and physical transformation, open up opportunities for water management system. Therefore an integrated approach like integrated water resource management (IWRM) system is required that responds to problems that are all interrelated. Alternate supply and demand management tools such as ground water recharge, rainwater harvesting, effective water pricing, reclaimed water use are suggested to meet the deficit of current supply system through the efficient use of the scarce resources available. Institutional reform and improved water planning are required to facilitate economic growth and social development. Finally, human resource development is identified as key factor for the sustainable effective management of this valuable resource.

Abstract Water security is the basis of sustainable human development. A new evaluation system of water security was established based on the natural–social dualistic water cycle theory, and then applied to characterize water security issues in China. At the national scale, the current state of water security was moderate, which was attributed to the improvement of water resource management level. However, it is still seriously inadequate in coordination of water use between ecological protection and socio-economic development, and wastewater treatment and reuse. Consequently, a resilient and integrated water management with adaptive capacity is needed. Moreover, the water security state in southern China was better than that in northern China, which was mainly attributed to the abundance of water resources in the south. Although the critical factors hindering water security were significantly different among China's 31 administrative regions, the low urban sewage reuse rate was a common factor, and irrigation efficiency was low in most parts of southern China. While in northern China, water resource overexploitation, polluted water quality and degraded aquatic ecosystems were common challenges. The results are consistent with the actual situations of China, and the related analysis can provide a reference for increasing regional water security.

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 Impact

Although Scotland is relatively water resource rich in a UK and European context, water resource scarcity can occur during exceptional dry periods such as those experienced in North West Scotland during July 2012. Precipitation and flow anomaly indices have been recently developed and introduced operationally by the Scottish Environment Protection Agency, in order to assess the severity of dry episodes and use this information within the decision-making process when managing the ecological implications of measures required to ensure continuity of water supply. The latest projections of future climate in the UK (UKCP09) point to warmer, drier summers across much of Scotland and, as such, imply an increased frequency of periods of water shortage. This study makes use of the results from a collaborative project in which projected values of climate variables have been used to derive projected river flows at a number of catchments across the UK. These datasets have been used to evaluate the change in frequency of significant precipitation and flow deficits in Scotland. The findings suggest a marked increase in frequency of summer water resource scarcity across much of Scotland which has implications for water resource management, particularly where current storage is relatively low.
