Abstract The status of the availability of water resources in DKI (Indonesia’s Special Region of) Jakarta has reached a critical phase. Determination of progressive tariffs by the DKI Jakarta Provincial Government in 2007 aimed to encourage water users to use water resources rationally and in a sustainable way. However, since the launch of the policy, there has been no evaluation to determine the effectiveness of these progressive tariffs. This research analysed empirical data to examine the effect of policy interventions on water use behaviour in DKI Jakarta. An analysis was carried out by calculating water usage before progressive tariffs were applied and comparing them to water use after the tariffs were applied. Another analysis calculated the number of customers before and after the implementation of progressive tariffs and compared the changes. The increase in water prices plotted are stated in nominal value by assuming the average level of inflation in Jakarta (especially the price of water) was nearly under 2 percent and the price of water was not controlled by the market mechanism The results of this study indicate that before progressive tariffs were applied, water consumption had declined despite an increase in the number of customers, however, water consumption increased after the implementation. This shows that progressive tariffs are effective instruments to distribute clean water access through cross-subsidies, however, it has no effect on consumption levels.

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.

Along with social economy development, the total water consumption increased year by year. The conflicts between water supply and water consumption is growing. Water resources optimization dispatch, which is used to allocate water resources to meet the demand of water user on both time scale and spatial scale, plays an important role in water resources management. Aiming at improving the spatial allocation ability of traditional optimization algorithms, a uniform spatial allocation strategy is proposed accordingly. The proposed method is used to improve the performance of optimization algorithm to obtain solutions which can uniform the water supply in spatial scale. Simulation results show that the maximum ratio of water deficiency gained by the proposed method is smaller than that obtained by the original algorithm. The proposed method is effective to balance the demand of water users in spatial scale. Copyright © 2018 Elsevier Ltd. All rights reserved.

Bases on the expansion of Geordie Coefficient, a analysis method for water consumption fairness have been set up, and the Geordie coefficients are calculated to describe the influence of population, GDP, water quantity on water use of China in 2009. Then water demand coefficient is put forward to estimate the reasons for unfairness of water use. Moreover, Geordie coefficient of the North and South of China is analyzed. The results show that Geordie Coefficient represents unfairness of water use, which result from the unfair factors, including population, GDP, and water quantity. The research can provide reference for reasonable configuration of the water resources.

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.

The Future

Water insecurity poses threats to both human welfare and ecological systems. Global water abstractions (extractions) have increased threefold over the period 1960–2010, and an increasing trend in abstractions is expected to continue. Rising water use is placing significant pressure on water resources, leading to depletion of surface and underground water systems, and exposing up to 4 billion people to high levels of seasonal or persistent water insecurity. Climate change is deepening the risks of water scarcity by increasing rainfall variability. By the 2050s, the water–climate change challenge could cause an additional 620 million people to live with chronic water shortage and increase by 75% the proportion of cropland exposed to drought. While there is no single solution to water scarcity or water justice, increasing the benefits of water use through better planning and incentives can help. Pricing is an effective tool to regulate water consumption for irrigation, for residential uses, and especially in response to droughts. For a water allocation to be efficient, the water price paid by users should be equal to the marginal economic cost of water supply. Accounting for all costs of supply is important even though, in practice, water prices are typically set to meet a range of social and political objectives. Dynamic water pricing provides a tool for increasing allocative efficiency in short-term water allocation and the long-term planning of water resources. A dynamic relationship exists between water consumption at a point in time and water scarcity in the future. Thus, dynamic water pricing schemes may take into account the benefit of consuming water at that time and also the water availability that could be used should a drought occur in the future. Dynamic water pricing can be applied with the risk-adjusted user cost (RAUC), which measures the risk impact of current water consumption on the welfare of future water users.

Using the panel data of 30 provinces in China from 1998 to 2017, we adopt a time-varying difference-in-differences (time-varying DID) model to estimate the impact of water rights trading scheme on regional water consumption. The results show that water rights trading can significantly promote water conservation in the pilot regions by 3.1% compared to that in the non-pilot regions, and a series of robustness tests show consistent results. Policy effects are mainly driven by improving water-use efficiency and adjusting water structure; that is, by transferring water resources from the agricultural sector to the other sectors, agricultural water efficiency is improved and water conflict among sectors is alleviated; thus, water saving is achieved. In addition, by constructing two indexes of regional water pressure and tradable water resources, our heterogeneity analysis shows that water rights trading performs better in areas with high water pressure and large tradable water resources. Under the high pressure of large water use and low water endowment, water rights trading will evidently reduce water consumption more so than in the low-pressure regions, and with water rights trading, it is hard to achieve a policy effect in regions without sufficient tradable water resources. This paper provides important policy implications for China for further promoting the water rights trading scheme in the field of resource conservation.

Economic development and increasing population density along the lower reaches of the Yellow river have challenged the river’s ability to meet human and ecological demand. The evaluation of the sustainability of water resources in the lower reaches of the Yellow River is of great significance for the achievement of high-quality development in the region. Based on an improved ecological footprint method considering soil water, the spatial and temporal evolution of the water resources ecological footprint and water resources carrying capacity and evaluates the utilization of water resources in the lower Yellow River are comprehensively evaluated. The results show that agricultural water consumption in the urban agglomerations in the lower reaches of the Yellow River occupies a major position in water consumption, accounting for more than 70%. In 2013–2017, the per capita water resources ecological footprint of the cities along the lower reaches of the Yellow River decreases every year, while the water resources carrying capacity is slightly fluctuating, but remains in a relatively stable state. The deficit situation has eased, falling by 54.52% in the past five years. The water use efficiency of the lower reaches of the Yellow River has increased every year, and the water resources conflict improved significantly, after the implementation of the new environmental policy in 2015. In terms of space, the cities with the smallest per capita ecological deficits include Zibo, Zhengzhou, and Laiwu City, and Dezhou, and Kaifeng and Binzhou City have the largest. Strict water resources management measures and water pollution prevention and control regulations should be formulated to improve the water use efficiency in these areas in order to solve the problem of water shortage.

And Control

This paper presents the conceptual framework for regulating water use in cases where water is a public good. Public agencies with an independent directive board can successfully manage such a situation. Through a comprehensive system of water permits, charging and control it is possible to effectively manage water resources. Together with the conceptual framework a practical application is presented. The case of the National Water Agency of Brazil - ANA - shows that it is possible to implement modern water resources management concepts in less developed countries. The benefits of this institutional arrangement are demonstrated in the case of managing water conflicts among water users. Two situations are described: the semi-arid water allocation for agricultural use in the Jaraguaribe River Basin in Ceara State and the conflict between the hydropower and navigation sectors in the Parana River Basin.
