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.

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.

Quality Water

The use of water for various human needs can be considered as an anthropogenic factor affecting water resources. The amount of water consumption is determined by the size of the population, the level of development and the state of housing and communal services, climatic conditions and other factors. The agricultural sector plays a significant role in the economy of the South and North Caucasian Federal Districts. The increase in agricultural production, especially in the southern drylands, is largely due to its reliable and high-quality water supply. A large share of the agricultural sector in the structure of water use determines that the water turnover coefficient in the region as a whole is much lower than the national one. The analysis of open sources revealed the key problems of water consumption in the region and enabled to identify specific measures for revising its structure.

Water is a core component of the nature environment. The problem of good quality water supply to the humans has been aggravating because the available resources of fresh water in some regions of the planet proved to be insufficient for satisfying all the consumer needs. Lack of fresh water has been a structural factor affecting the global economic development, with drinking water acquiring the characteristics of a strategic commodity. These circumstances raise the importance of solutions on saving fresh water resources and ways of their rational use from the local level to the global one. The article contains a description of the current situation with water supply and water consumption in Ukraine. As regards water supply, Ukraine, according to the hydrological classification, is undergoing water stress, in parallel with extra water consumption and high water intensity in the domestic production sector. The subject of the study is water intensity of the gross domestic product, its main factors and ways of reduction. The object of the study is seven Ukrainian regions across which the river Dnieper flows, and the city of Kyiv. A significant variation of water intensity is observed in administrative and territorial units located in the Dnieper basin, which is caused by the varying industrial capacities, varying systems of technical water supply at industrial enterprises, and varying scopes of fresh water use in water supply for agricultural and utility needs, lack of advanced systems for water supply in some of the regions, which causes large losses of water and high water intensity in some production facilities. The impact from the above mentioned factors on the regional water intensity is assessed by the regression model on panel data. The specific conditions of the business operation in some regions of the Dnieper basin are represented in the model by dummy variables. By the model of water intensity of GDP, the largest one is the impact from industrial specialization of a region (especially Dnipropetrovsk, Zaporizhzhia, Kyiv and Kherson regions), the existence of water recycling systems at industrial enterprises, scopes of water drainage and capacities of sewage treatment plants. Effective use, rehabilitation and protection of water resources, improvement of water quality, and reduction of water intensity in the production facilities through taking technological and economic measures in water consumption are considered as important factors of the national security.

Hydrological Droughts

Abstract. Managing water–human systems during water shortages or droughts is key to avoid the overexploitation of water resources and, in particular, groundwater. Groundwater is a crucial water resource during droughts as it sustains both environmental and anthropogenic water demand. Drought management is often guided by drought policies, to avoid crisis management, and actively introduced management strategies. However, the impact of drought management strategies on hydrological droughts is rarely assessed. In this study, we present a newly developed socio-hydrological model, simulating the relation between water availability and managed water use over 3 decades. Thereby, we aim to assess the impact of drought policies on both baseflow and groundwater droughts. We tested this model in an idealised virtual catchment based on climate data, water resource management practices and drought policies in England. The model includes surface water storage (reservoir), groundwater storage for a range of hydrogeological conditions and optional imported surface water or groundwater. These modelled water sources can all be used to satisfy anthropogenic and environmental water demand. We tested the following four aspects of drought management strategies: (1) increased water supply, (2) restricted water demand, (3) conjunctive water use and (4) maintained environmental flow requirements by restricting groundwater abstractions. These four strategies were evaluated in separate and combined scenarios. Results show mitigated droughts for both baseflow and groundwater droughts in scenarios applying conjunctive use, particularly in systems with small groundwater storage. In systems with large groundwater storage, maintaining environmental flows reduces hydrological droughts most. Scenarios increasing water supply or restricting water demand have an opposing effect on hydrological droughts, although these scenarios are in balance when combined at the same time. Most combined scenarios reduce the severity and occurrence of hydrological droughts, given an incremental dependency on imported water that satisfies up to a third of the total anthropogenic water demand. The necessity for importing water shows the considerable pressure on water resources, and the delicate balance of water–human systems during droughts calls for short-term and long-term sustainability targets within drought policies.

The article assesses the impact of internal and external factors on the economic security of the region in foreign trade activities. Negative consequences of the foreign economic activities on economic security of the Stavropol Territory are analyzed. Types of the risks enterprises may face when entering the foreign market are considered. Protectionist arguments in favor of pursuing a free trade policy are presented and argued, which implies a staged formation of a mechanism to efficiently counteract threats to the external economic security of the region.The study considers the level and dynamics of the main macroeconomic indicators of the subjects of the North Caucasus Federal District as compared to the average Russian achievements, the resource potential, problems of the economic development of the macroregion, prerequisites for the formation of the state policy on supporting the region. It substantiates the top priority directions of long-term socio-economic development of subjects in order to overcome the pervasive arrearage of the economy and social area.

Aim. The study is aimed at examining the regional specifics of using water resources in the Russian‐Kazakhstan transboundary region, taking the current hydroclimatic situation into account.Methods. Statistical data on the availability and use of water resources in the regions of the Russian Federation and the Republic of Kazakhstan served as the initial data for the study. A comparative assessment of water supply was carried out applying traditional procedures widely used in Russia and abroad. The following indicators of water use efficiency were used: volumes of circulating and re‐sequential water supply (million m3), water losses during transportation (million m3) and water intensity of the gross regional product (GRP).Results. It was found that, over the past 20 years, a significant transformation of the water consumption structure has taken place in the studied regions. In the Russian regions, the most serious transformation of the consumption structure occurred in the agricultural sector. A comparative assessment of water supply suggests that most regions within the Russian‐Kazakhstan transboundary territory are characterized by relatively high levels of water availability.Main conclusions. The results indicate a significant impact of socio‐economic transformations in the Russian‐Kazakhstan region on the structure of water consumption, water supply, as well as indicators of water resource efficiency. The current water management problem consists in guaranteed provision of the population and economy with fresh water under the conditions of the spatio‐temporal variability of the river flow. Thus, the integrated management of water resources within the Russian‐Kazakhstan transboundary region should be based on improving the effi‐ ciency of water use in all sectors of the water economy, taking modern hydroclimatic changes into account.

The Impact

This study aims to evaluate impacts of reducing toilet flush volume from 6.8 to 4.8 Lpf with laboratory and field studies. In laboratory, 260 tests were performed including water consumption, waste removal and solid transport tests, in 20 different toilets produced by national and international manufacturers. These tests demonstrated that a simple reduction in flush tank water level was not a viable solution for reducing flush volume, due to flush energy loss. Toilets are designed to work with certain water volume, and reducing this volume without studying the consequences that this could cause, can make with the toilet fail. Toilets approved according the standards ABNT NBR15097, ABNT NBR15491 and ASMEA112.19.2 were installed in 10 houses. The monitoring of water consumption and sewage system videos were conducted during eight months. When 6.8-Lpf toilets were installed, the average toilet water consumption was 16.6L/inhabitant/day. For 4.8-Lpf toilets, this value increased to 17.6. The number of flushes/person/day increased after toilets replacement, indicating that users applied successive flushes. Videos showed blockages in sewage system horizontal pipes. Findings from this study suggest that low-flush toilets do not decrease total water use, and may result in increased water use. In addition, they can cause clogging and solid deposit on sewage system. Practical application: Many management failures have affected the world water availability. Water demand has increased with population growth, and unless the equilibrium between water demand and supply is restored, the world will face increasing water shortage. However, it is essential to study the way of reducing water consumption. Without an effective analysis, instead of bringing benefits to population, water consumption reduction can lead to clogging and negative consequences on sewage system performance, causing disorder to them. It is recommended that manufacturers did not reduce the toilet water consumption without a study on the impact caused on the sewage systems, as well as designers should be careful when specifying sanitary appliances.

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-use), 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 would influence awareness for water resources so that water consumption in the dry season would be smaller than that in the rainy season. In addition, it was examined whether the differences in water resources such as public waterworks or non-public waterworks (i.e., community waterworks, mountainous water and groundwater), affected the amount of water use. A small-sized accumulative water meter was developed for measurement. This survey provides important information for water demand estimations and water supply planning in middle-developed countries where water consumption is expected to increase in future.

The Impact

Information regarding domestic water consumption is vital, as the Kathmandu Valley will soon be implementing the Melamchi Water Supply Project; however, updated information on the current situation after the 2015 Gorkha Earthquake (GEQ) is still lacking. We investigated the dynamics of domestic water consumption pre- and post-GEQ. The piped water supply was short, and consumption varied widely across the Kathmandu Upatyaka Khanepani Limited (KUKL) branches and altitude. The reduction in piped, ground, and jar water consumption and the increase in tanker water consumption post-GEQ appeared to be due to the impact of the GEQ. However, the impact did not appear to be prominent on per capita water consumption, although it was reduced from 117 to 99 L post-GEQ. Piped, ground, and tanker water use were associated with an increase and jar water use was associated with a decrease in water consumption. Despite improvements in quantity, inequality in water consumption and inequity in affordability across wealth status was well established. This study suggests to KUKL the areas of priority where improvements to supply are required, and recommends an emphasis on resuming performance. Policy planners should consider the existing inequity in affordability, which is a major issue in the United Nations Sustainable Development Goals.

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.
