The article examines the problem of fresh water, since in terms of water supply from its own resources per capita and per 1 km2, the republic is 8 times behind Georgia, 2 times behind Armenia. Significant water consumption in Azerbaijan is caused by its arid territory with a predominance of active temperature and a lack of precipitation, which leads to intensive irrigation of crops. At the same time, artificial irrigation is used on 70% of the cultivated land.

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.

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.

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.

The current situation in irrigation in Serbia, observed through total number of irrigation systems, in other words through areas where those systems were constructed, is not satisfactory—neither according to range, nor according to technical equipment and the level of their use. The level of development that has been reached does not satisfy the requirements of stable and efficient agricultural production. Irrigation has not been applied properly in our agriculture because every time when a bumper crop year happens, irrigation is delayed. Irrigation is applied to less than 1% of cultivable soil in the Republic of Serbia. A few very successful results in agricultural production where irrigation was applied point out the perspective on irrigation in Serbia. In the development of irrigation, the priority should be given to renovation of old and construction of new small and big systems, to making changes in structures of production in agriculture, to modernization of mechanization and creation of economic conditions necessary for the use of old and construction of new production capacity aiming to increase employment. Because of the fact that Serbia is poor in water resources of its own, as well as that transit water becomes more and more uncertain in the future regarding its quality and quantity, planned rationalization of water consumption must be one of strategic points for future development in Serbia, as well as obligatory reduction in specific water consumption in all spheres of its use.

<p>Since the middle of the 20th century, urban-tourist development in tourist destinations on the Mediterranean coast has required the creation of complex water supply systems to guarantee a growing water demand. At present, the challenges posed by climate change around the management of water resources requires the implementation of adequate water policies and sustainable environmental solutions to foster the adaptation to a foreseeable future characterized by lower availability of conventional water resources and more recurrent and intense droughts. In this context, the link between the scientific field, the stakeholders from the tourism sector, and the decision-makers is vital to favor viable, effective, and consensual solutions that shift the focus from the objective of guarantee tourist water demand to a sustainability scenario from both an environmental, economic, and social point of view. Therefore, it is relevant to question whether there is a large gap between the actions and focus of attention in each of these three areas (scientific, decision-makers, and stakeholders). In other words, does scientific research related to water consumption by the tourism sector adequately respond to the knowledge needs required by stakeholders and decision-makers to achieve the aforementioned sustainability objectives? Through a literature review, this study addresses the main topics, methodologies, and results related to water consumption in hotels on the Spanish Mediterranean coast and their possible impact on the actions made by managers, decision-makers or stakeholders from the tourism sector. To evaluate the science-policy interface, it has also been made a policy review of the main laws, regulations, and plans developed by the different levels of public administration and other private entities in the tourism sector concerning water consumption in hotels, for the Benidorm case study, located in the southeast of Spain. To identify the measures implemented by stakeholders from the tourism sector to reduce water consumption and their vision about the challenges and barriers in this issue, we have taken into account the results of previous projects in which more than twenty surveys and interviews have been carried out to the hotel managers as well as to the Benidorm hotel association (HOSBEC). Likewise, to contextualize the results of these surveys and interviews, we have analyzed the raw water supply data provided by the entity in charge of this service, the Marina Baja Water Consortium, as well as billing and smart meter data from the hotels, provided by the company in charge of the local water supply service, Hidraqua. The results will make possible to highlight the links and differences found between the problems and research approaches raised from the scientific field, the regulations and plans proposed by the public administration and other private decision-makers and the actions and future challenges identified by the tourism sector in the city of Benidorm. The identification of the existing gaps between the three areas (scientists, policy-makers, and stakeholders) will be useful to reshape the agenda of future research and re-think the role of science when responding to managers and decision-makers’ requests on water management and tourism nexus.</p>

Abstract Jinan is a city that typifies the water resource shortage in North China. This study selected nine indices to evaluate the regional water resources carrying capacity (WRCC), which is an important constraining factor in relation to socioeconomic development and the ecological environment. The AHP-CRITIC weighting method was applied to determine the index weighting, and WRCC dynamics during 2011–2016 were analysed and evaluated quantitatively using the fuzzy comprehensive evaluation method. The results revealed the following. (1) During 2011–2016, the comprehensive score of the WRCC was <0.4, indicating poor WRCC. (2) The degree membership of the average evaluation results to V1, V2, and V3 increased successively during 2011–2016. The degree membership of V2 in 2011–2013 was greater than that of V3; however, the situation was reversed during 2014–2016. (3) The indices of available amount of water resources per capita, utilization rate of water resources, water supply per capita, modulus of water supply, quota of domestic water demand, and population density were factors that affected the WRCC of Jinan unfavourably. Conversely, the indices of water demand per 10,000 Yuan industrial output value and water use rate of the ecological environment were factors that played positive roles in improving the WRCC.

On the example of single-industry towns of the Republic of Karelia the article shows the possibility of restoring the activities of enterprises depending on the state of engineering support of water supply systems. There was a decrease in water consumption, high wear of water treatment plants, the lack of reagent treatment of colored water and, as a result, ineffi cient operation of facilities. It is shown that the reconstruction is possible with the application of the investment program. Projects have been developed for the reconstruction of the technological scheme for purifying low-turbid, high-color water and creating a circulating system for cleaning the wash water of contact illuminators.
