Abstract. The direct measurement of the micro-components of water consumption (i.e., consumption by each residential activity, such as toilet, laundry, bath, and kitchen) both in the dry season and in the rainy season was conducted in Chiang Mai, Thailand. It was expected that rainfall differences between the dry and rainy season could influence awareness for water resources so that water consumption in the dry season may be smaller than that in the rainy season. It was also examined that whether the differences in water resources such as public waterworks or non-public waterworks like community waterworks, mountainous water and groundwater, affect the water use amount. A small-sized accumulative water meter was developed for measurement. This survey can provide the important information for water demand estimation and water supply planning in middle-developed countries where their water consumption should be expected to increase from here on.

The Impact

The key task of the societal development is to ensure effective management of water resources. As a consequence of aggravation of water problems in the world, the issues of sustainable and guaranteed access to water are considered as one of the components of ensuring food security, conservation and restoration recovery of natural resources, which are the basis of life support for the population. To date, the regulation of water resources in the North Caucasus experiences difficulties resulting from fragmented water use, unequal access to water, and contradictory legislation in the field of water use regulation. These problems are compounded by two factors: climate change and demographic situation. The main problem of water consumption in Russia is the irrational and ineffective use of water resources and, as a result, high specific water consumption. In the North Caucasus, water consumption is currently one of the highest in Russia. The characteristics of the impact on water resources are directly related to the use of water, the main elements of which are the water withdrawal from natural sources, the use of water and the discharge of wastewater. Based on open statistical sources, we analyzed the current situation in the use of water resources in the North Caucasus. The North Caucasus is characterized by problems similar to those of many regions of the country, in particular, large losses during transportation due to the emergency state of water supply networks and treatment facilities. Water supply problems in the North Caucasus are expected to worsen in the future. If urgent measures are not taken, the complex of problems will only accumulate. To overcome their negative consequences, it is necessary to revise the water use strategy and change the water consumption structure.

The Impact

Designs of water distribution systems and water resources planning and management can be obtained from a comprehensive investigation and analysis of water consumption data in real life systems. Water consumption patterns for domestic purposes were monitored at 145 households over a three-year period. Electric flow meters were installed at the ends of all of the household water taps. Water consumption patterns were analyzed to configure the water demand trends for social and cultural factors. Economic factors such as monthly income and the area of the floor plan were investigated to determine the impact of resident wealth on the patterns of water consumption. Water use data collected by a public water resources management firm in Korea, Kwater, had been filtered using both physical and probabilistic criteria to improve the credibility of the analysis. Both the Mann-Kendall and Spearman's Rho tests were used to perform the trend analysis. Distinct factors in the patterns of water consumption can be determined to cause both increasing and decreasing trends in water use. Analysis of this data provides the basis of parameter configuration for a reasonable design of a domestic water-demand prediction model.

Use Efficiency

Worldwide, water scarcity threatens delivery of water to urban centers. Increasing water use efficiency (WUE) is often recommended to reduce water demand, especially in water-scarce areas. In this paper, agricultural water use efficiency (AWUE) is examined using the super-efficient data envelopment analysis (DEA) approach in Xi'an in Northwest China at a temporal and spatial level. The grey systems analysis technique was then adopted to identify the factors that influenced the efficiency differentials under the shortage of water resources. From the perspective of temporal scales, the AWUE increased year by year during 2004–2012, and the highest (2.05) was obtained in 2009. Additionally, the AWUE was the best in the urban area at the spatial scale. Moreover, the key influencing factors of the AWUE are the financial situations and agricultural water-saving technology. Finally, we identified several knowledge gaps and proposed water-saving strategies for increasing AWUE and reducing its water demand by: (1) improving irrigation practices (timing and amounts) based on compatible water-saving techniques; (2) maximizing regional WUE by managing water resources and allocation at regional scales as well as enhancing coordination among Chinese water governance institutes.

Purpose This study aims to structure research on water resources in the hotel industry, identifying the key areas and research gaps in this field. Design/methodology/approach A systematic literature review of water use in the hotel industry has been performed using the Scopus and Web of Science databases. From 515 articles selected between the years 2000 and 2019, a sample of 58 articles was used to structure existing research on this subject. Findings Research is classified into four groups: water consumption, water management, impacts of water use and good practices, with different research methods and topics within each one. Existing research gaps and their causes are also discussed. The results show how academic research can help strengthen international methodologies that measure sustainability. Research limitations/implications Because of the search process, some publications on water consumption in the hotel industry may have been missed; also book chapters and conference papers were excluded. Furthermore, the authors recognise some subjectivity in the classification of articles. Originality/value To the authors’ knowledge, this is the first systematic analysis focussed on water use in the hotel industry. The findings can be used to build a research framework for this area, establishing an approach to cover research gaps and to connect academic research with general methodologies and indicators of sustainability, as well as improving data collection techniques in this field.

The purpose of this study is assessment of water use in the Central Region of the Republic of Moldova. The main topics presented in this paper are: 1) assessment of water resources in the Central Region of the Republic of Moldova; 2) tendencies of water consumption on the abstracted sources and on the main usage categories; 3) spatial and branch analysis of water use; 5) the main problems of water use and protection in the region of study. In the region of study are concentrated about 2/3 of groundwater reserves of Republic of Moldova. From surface sources is abstracted ≈3/4 of total volume of water used and over 60% of water is used by households. Outside of Chisinau, over 70% of the water is abstracted from underground sources and is used for various agricultural needs. In the 2007-2017 years, the volume of water use registers a significant decrease which is conditioned, mainly, by decreasing of water abstracted from surface sources and used for agricultural activities, especially for irrigation.
