water security is under threat worldwide from climate change. A warming climate would accelerate evaporationand cryosphere melting, leading to reduced water availability and unpredictable water supply. However, thewater crisis in the Northern Slope of Tianshan Mountains(NSTM) faces dual challenges because water demandsforfast-growing urban areas have put heavy pressure on water resources. The mountain-oasis-desert system featuresglacier-fed rivers that sustain intensive water use in the oasis and end in the desert as fragile terminal *** complex balance between water conservation and economic development is subtle. This paper investigateschanges in hydroclimatic variables and water security-related issues on the NSTM. The spatiotemporal variationsin glaciers, climatic variables, rivers, lakes and reservoirs, groundwater, surface water, human water use, andstreamflow were analyzed for the past four decades. The results show that temperature in the NSTM exhibitedan apparent upward trend with a more significant warming rate in the higher altitude regions. Glacier massloss and shrinkage was strong. The average annual streamflow increased from 1980-1989 to 2006–2011 at mosthydrological stations. The monthly dynamics of surface water area showed notable variability at both inter-annual and seasonal scales, revealing the impacts of both natural and anthropogenic drivers on surface wateravailability in the region. The terrestrial water storage anomaly showed a decreasing trend, which might berelated to groundwater pumping for irrigation. Human water use for agriculture and industry grew with theincrease in cultivated land area and gross domestic product (GDP). The increased agricultural water use wasstrongly associated with the expansion of oases. It is unclear whether water availability would remain high underfuture climatic and hydrological uncertainties, posing challenges to water management. In the context of rapidurban growth and climate change, balancing water f

Journal of Geoscience and Environment Protection 2022年第10期10卷 1-17页

作者： Elias Salameh University of Jordan Amman Jordan

This study discusses the present water security situation in Jordan and delineates the required policies and programs to reach at a more robust and resilient water security situation. Although Jordan has achieved much in securing the different components of its water sector system, some components have still to be adequately addressed and others strengthened. Increasing the available water resources, which is practically only possible by desalinating sea water at Aqaba under sole Jordanian sovereignty, is found to be the most important and vital issue in improving the country’s water security situation. It improves the security issues of providing dearly needed additional water, releases the overexploited aquifers and saves them from depletion and quality deterioration, allows introducing new industries to Jordan, de-sharpens the conflict on the shared water resources with Jordan’s neighboring countries and is expected to render these conflicts to a problem of royalty on water resources and not as it is at present a social, economic, human, environmental and political conflict. Desalination will also make Jordan more resilient to climate change. Infrastructure security must be strengthened in Jordan both against natural hazards and against intended sabotage and damage. water quality protection from pollution and deterioration has still to be adequately addressed requiring strengthening of laws and regulations and their application. The already delineated surface and groundwater protection zones have to be strictly adhered when licensing human activities in addition to implementing cybersecurity best practices. In addition, technology-dependent management tools have to be strongly advanced using integrated water resources management to ensure sustainable resource management, detection and repair of physical water losses and illegal water tapings, pricing water at its opportunity cost, irrigation modernization, strict environmental impacts assessment and application w

RUTLEDGE Abbas JAMALIPOUR interdisciplinary Photonics Laboratories (iPL) School of Chemistry The University of Sydney NSW 2006 Australia School of Chemistry The University of Sydney NSW 2006 Australia Wireless Networking Group (WING) School of Electrical and Information Engineering The University of Sydney NSW2006 Australia

Early detection of environmental disruption, unintentional or otherwise, is increasingly desired to ensure hazard minimization in many settings. Here, using a field-portable, smartphone fluorimeter to assess water quality based on the pH response of a designer probe, a map of pH of public tap water sites has been obtained. A custom designed Android application digitally processed and mapped the results utilizing the global positioning system （GPS） service of the smartphone. The map generated indicates no disruption in pH for all sites measured, and all the data are assessed to fall inside the upper limit of local government regulations, consistent with authority reported measurements. This implementation demonstrates a new security concept： network environmental forensics utilizing the potential of novel smartgrid analysis with wireless sensors for the detection of potential disruption to water quality at any point in the city. This concept is applicable across all smartgrid strategies within the next generation of the Internet of Things and can be extended on national and global scales to address a range of target analytes, both chemical and biological.

Limited water resources, increasing demand, low use efficiency, and serious pollution result in severe water resource difficult in China. The evaluation of addressing water problems and the search for effective countermeasures that ensure sustainable water use are key to China's sustainable development. The “compound water security” consists of food security, life security, environmental security, and economic security. By establishing a conceptual model, the water security of China has been simulated in terms of four scenarios called BAU(the business-as-usual scenario), TEC(the technology and economics scenario), IVL(the institution, values, and lifestyles scenario) and TSD(toward sustainable development) in this paper. The results indicated that water crises, especially water shortages, are being experienced now and will continue to do so for a relatively long time in China and that it is possible to reach a basic balance between supply and demand of water and grain under the TSD developing pattern by a series of approaches including technological innovation, policy adjustments, and behaviour inducement.

In order to attain the water security goal, specifically in highly developingareas, delineation of pure and sustainable water resources is of utmostpriority. In the present study, a preliminary investigation of the groundwaterchemistry was carried out. This was followed by assessing the suitabilityof groundwater to be used as an alternative and reliable resource for publicuse in the Khoyrasole block, Birbhum district, India. Altogether 15(fifteen)samples of groundwater, were collected from bore wells spread well overthe Khoyrasole block have been considered. After completing the chemicalanalysis of the groundwater samples, the study revealed the quality ofgroundwater. The spatial distribution of groundwater quality parameterssuch as pH, Total Dissolved solids (TDS), Hardness, Calcium, Magnesium,Sodium, Potassium, Iron, Chloride, Carbonate, Bicarbonate, Sulphate,Nitrate and Fluoride have also been studied. High to very high levels ofiron and fluoride have been observed to be present in 67% and53% of thesamples respectively. Based upon the calculated parameters like SAR,MAR, PI and Chloro Alkaline Indices, groundwater of Khoyrasole blockis majorly suitable for the purpose of agriculture and irrigation. Plotting ofionic scatter plots and geochemical facies also indicate the water samplesto be of “fresh water” category, with no dominant cation or anion playing aselectively dominant role in influencing the groundwater chemistry in thestudy area.

Weather extremes negatively affect socioeconomic developments in arid and semi-arid areas (ASALs) and increase vulnerability of residents to food and water insecurity. Thus, communities adapt to such extremes of weather using Traditional Ecological Knowledge (TEK) and/or Modern Technologies. Modern farming technologies and land resource developments in ASALs have in past ignored TEK, and in most cases led to undesired outcomes. It’s against this backdrop that this study was conceived to assess TEK among the Turkana people, its application and contribution to food and water security. The research adopted a cross-sectional social survey in collecting data from Central Turkana Sub-County residents. The study revealed that the Turkana people possess vast knowledge related to their environment;that this TEK plays a significant role in food production, preservation and in natural resource management. For instance, in 82% of the respondents use TEK in enhancing livestock production through the selection of livestock species that are suitable and drought tolerant;over 70% of them use TEK in reducing risk associated with livestock losses due to prolonged droughts. Further, TEK influenced the development and conservation of the water resources (r = 0.631;p security. TEK should be incorporated into the decision-making processes involving development projects within the ASALs.
