“…Shi et al, (2010) believed that the meaning of water resources safety should include four aspects: natural attribute, ecological environment attribute, social economic attribute and humanistic attribute. Leya et al, (2022) thought that water resources safety referred to water resources safety issues caused by water resource lack, pollution of water resources and flood and drought disasters. Although current understandings on the connotation of urban water resources safety are different, they all agree that it has multi-level and multi-objective.…”

“…Based on relevant research literatures on water resources safety grade standards (Liu et al, 2020;Peng et al, 2022;Leya et al, 2022), combined with the actual situation of water supply, water use and management in karst areas, and according to expert opinions, appropriate adjustments were made to water resources safety standards, and water resources safety grade was divided into five levels "safe, relatively safe, critically safe, unsafe and extremely unsafe", and grading standards of each indicator were determined (Table 2).…”

Quantitative evaluations on water resources safety in karst areas are of great significance for enacting logical water resources development policies, promoting the sustainability of water resources and realizing sustainable socioeconomic progress. Therefore, according to special characteristics of hydrology and water resources in karst regions of southwestern China, this study constructed an evaluation indicator frame of water resources safety from five aspects: Water resources occurring (WRO), Water environment condition (WEC), “Engineering” water scarcity (EWS), Water resources utilization (WRU) and Water resources management (WRM). Combined weights of assessment indexes were calculated by analytic hierarchy process (AHP) and entropy-right method, and an assessment model of water resources safety in karst regions was constructed based on the coupling of analytical comparison method and alterable vague sets. Taking Guiyang as an example, the water resources safety situation of Guiyang from 2013 to 2022 was assessed with this model and its main obstacle factors were analyzed. Results indicate that the level of water resources safety in Guiyang is on the rise, and the safety level rises from unsafe level to relatively safe level. Water resources utilization is the primary element affecting water resources safety of Guiyang. Total water resources volume, water yielding modulus, consumptive use of water per 10,000 Yuan GDP and exploitation and utilization rate of water resources are primary obstacle factors to the improvement of water resources safety level. The improvement of water resources provision, water resources using efficiency and water resources management all show that human behaviour has a significant impact on water resources safety. The assessment model can impersonally reflect temporal evolution features and main constraints of water resources safety in karst regions, and evaluation results are close to the actual situation, which can provide an effective, feasible and intuitive method for water resources safety evaluation in karst areas.

“…The United Nations World Water Development Report (2023) has estimated that 2.4 billion people living in urban areas, up to half of the world's urban population, could experience water scarcity by 2050 [9]. This is particularly true for peri-urban areas that may not be connected to the central water infrastructure [10,11]. These communities may experience what Adeyeye et al [12] refer to as "water marginality".…”

Understanding contemporary challenges for water security in Ulaanbaatar, a semi-arid region in Mongolia

Water security is one of the biggest challenges of the 21st century. Understanding context-specific challenges and opportunities around this issue is key to improving water systems globally. This paper explores the current state of urban water security in Ulaanbaatar, Mongolia’s capital city. Ulaanbaatar is home to more than 40% of the country’s population and 60% of its national GDP. The city is located in the Tuul River basin and relies almost entirely on groundwater aquifers of the Tuul River for its supply of clean drinking water. In recent years, socio-economic stressors resulting from rapid urbanisation and environmental pressures have intensified the levels of degradation of the Tuul River and intensified the risks of water insecurity for the population of Ulaanbaatar. First, this paper draws from an extensive literature review and document analysis to provide an overview of the current state of urban water security in Ulaanbaatar. Secondly, the discussion is substantiated with information from key informant interviews which aim to explain the ongoing challenges for water security in Ulaanbaatar and suggest paths for improvement. This study finds that the main challenges for water security in Ulaanbaatar are data unavailability, limited human and financial resources across public water sector agencies, exacerbating flood risk and ongoing water quality disparities between the central city area and peri-urban ger districts.

“…Water is the basic need of human beings and gained importance due to the scarcity of freshwater. 1 This problem is more serious in developing countries; therefore, water has become a valuable commodity. 2 , 3 Different studies indicate that more than half the world’s population is not having access to safe drinking water and many people die every year due to contaminated drinking water.…”

Introduction Water is the basic need of human beings and there is no substitute for water. This research was conducted to analyze public willingness to use water from filtration plants installed by public own Organizations and which psychological factors may help them to decide to use safe water. Methods There ought to be some nudges in the right direction to encourage people to use water filters. A questionnaire was adopted from the literature for this research. PLS-SEM is used to evaluate data to check the connection among variables since it is the most recommended way for assessing and predicting explained variables to account for the largest latent variance, and PLS-SEM is one of the most effective approaches for predicting outcomes. Results PLS-SEM direct path analysis revealed that hypotheses H1-H6 were accepted and the gender and levels of education of the respondents as control variables, gender and education showed insignificant relationships with WUFWFP. Age showed a substantial relationship as a moderator variable between WQK*Age, and HC*Age with a willingness to use filter water from filtration plants=WUFWFP, while the rest of the variables showed an insignificant relationship. Discussion As per our results, H1a and H3a have a significant relationship as moderator variables between IV and DV, while H2a, H4a, H5a, and H6a did not show any relationship as moderator variables between IV and DV. Hence H1a and H3a were accepted while the rest of the moderator was rejected under this research. This study would be helpful for the decision-makers and planners to take proper sustainable measures to address the repercussions of urbanization and land use changes to protect the ecosystem.
