A quantitative evaluation of the provision of the Baikal transboundary region, its districts and aimags with the surface sources of centralized water supply is given on the ground of a special method of mapping and definition of sustainable streamflow. The minimum streamflow data in a limiting winter season has been accepted as the values of sustainable streamflow, thus considering the six different zones of water availability. The values of the sustainable streamflow and water situation of the population were obtained for the 86 municipal regions of Russia (33 districts of the Irkutsk region, 31 – Zabaykalsky Krai, 21 – the Republic of Buryatia, 1 – the Republic of Tyva) and 12 aimags of Mongolia. The problem of low water availability in Zabaykalsky Krai and, especially, Mongolia, which has a great difficulty with the water supply. The main factors which have determined the sharp unevenness of the territorial distribution of the sustainable streamflow and the sources of the centralized water supply.

The article discusses the role of coordination in the development of tourism and in increasing social and economic benefits of tourism activities. Defined is the concept of "coordination" with regard to tourism activities. The article examines levels of coordination in tourism: global (international), national, regional (local). The author suggests the definition of the concept of "coordination mechanism improving the socio-economic benefits of tourism activities." The article considers its practical manifestation in the regions of the Baikal area (Irkutsk region and the Republic of Buryatia), demonstrating that, despite the presence in these tourist destinations of public and private institutions that are able to coordinate the sphere of recreation and tourism, the effects of coordination mechanisms in these regions are different. That is, the effective coordination of tourist activity presupposes not only forms of coordination, but also some attributes to characterize an effective coordination mechanism. Defined are the attributes of effective coordination mechanism, which include: the ability of the central coordinating unit to coordinate goals, business processes and actions of actors in sphere of recreation and tourism; the presence of a single information system, which determines the method for producing and distributing information among actors in the sphere of recreation and tourism; adequate organizational structure of the central coordinating unit; the overall strategy of forming relationships between actors in the sphere of recreation and tourism; a system for monitoring coordination; informal relations. The author conducts an analysis of the relevant coordination mechanisms to improve the socio-economic benefits of tourism activities in the Irkutsk region and the Republic of Buryatia. It is concluded that to improve the socio-economic benefits of tourism activities there is a need for not only a coordinating mechanism per se, but also its corresponding efficient attribute.

The paper presents a hygienic quality assessment of water from sources in the Irkutsk Region (Russia) used for public drinking water supply. The aim of the study is to assess health risks to the population of Bratsk and the Bratsk District, which is associated with the exposure to chemicals coming with drinking water from the public water supply system. Risk of occurrence and development of non-carcinogenic effects is assessed for separate age groups using a special method. Based on the risk assessment methodology, non-carcinogenic risks for children and adults are described in quantitative terms. The total health risk of the test groups associated with the oral intake of chemicals with drinking water is estimated as negligible and, therefore, does not need to be reduced through additional measures. Lead and fluoride contents in drinking water are the major contributors to the risk level (59.5–68.4%). There is a risk of developing blood disorders and cardiovascular diseases in children of Bratsk (HI = 1.19), as well as bone tissue and teeth disorders in children of Bikey village, Bratsk District (HI = 1.10).

The City

The drinking water supply of the city of Nikšić, the second largest city in the Republic of Montenegro, is secured from a nearby karstic groundwater resources. Water is transported from two different directions (two sources) into the distribution system. At the end of the distribution system, on the opposite side of water resources, there is a counter tank, as the only storage capacity for leveling the inflow and consumption in the system. However, the interplay of the three vital water supply capacities (two water sources and counter tank) does not meet the requirements of regular supply, to the point where it is necessary to disconnect the tank, from regular operation. The existing system, which operates without leveling space, is fraught with numerous problems, ranging from the appearance of significant temporal and spatial pressure variations, to the inability of delivering the needed quantities to the peripheral parts of the system, in seasonal peaks of consumption. During International project Drinkadria (2013–2016), efforts for solving numerated problems were done. This paper provides an overview of activities on system operation analysis, based on simulation modeling and definition of technical solution, proposed in the form of subzoning. Realization of proposed subzones will put all capacities in the full operation state, with the realization of stable pressures in the system, and with a regular supply of all parts of the system in all predictable modes of consumption.

The reference services in Cameroonian libraries are lagging in the exercise of their activities. Thus, this study raises the problem of the organization and functioning of reference services in the libraries of Cameroon. The purpose of the research is to provide an updated view of research issues in reference services in the libraries of the Republic of Cameroon. It outlines the definition of the notion «reference service»; opens his essence, characteristics, and content; reveals the current state of reference services for Cameroonian libraries and the main factors influencing the activities of reference services in libraries of Cameroon. The research defines the attributes of a reference librarian and proposes and defines several ways and trends for the future improvement of reference services in the libraries of Cameroon. As part of the research conducted, the following methods were used: observation and interviews carried out in Cameroon libraries. The results of this study would, no doubt, be of great benefit to all libraries in Cameroon and should ideally be completed by the Cameroonian reference services.

Despite the fact that the Russian Federation, in general, is among the water-sufficient countries, some of its regions are experiencing water lack. One of such regions is the Republic of Crimea, where the situation with water supply is a serious problem after the water supply through the North Crimean canal has been stopped since 2014. The authors present the results of the spatial database’s development with the aggregated materials about the surface runoff and groundwater resources, the factors affecting their formation, collected in the research process. The database includes the information about the volumes of water consumption and the quality of the water used in the Crimean peninsula. The structure of the database created as a cartographic support for the assessment of water availability in the region is described. On the basis of the obtained data, a series of maps is created, which is an example of structuring the data and the possibility of their targeted use for the rapid display of such indicators, that will enable us to present the water availability of the Crimean regions in various aspects, as well as for solving other applied problems.

Yield Quality

Water supply of crop plants is the most essential physiological condition influencing quality and quantity performance of grain yield. In a 12-year experimental series of winter wheat agronomic trials run at the Nagygombos experimental site (Hungary) the effect of water availability has been studied. The location represents the typical average lowland conditions of the country, the annual precipitation of the experimental site belonging to the 550–600 mm belt of the Northern edges of the Great Hungarian Plain, while the average depth of groundwater varies between 2 to 3 metres. Crop years with various precipitation patterns have had different impacts on crop yield quality and quantity. Yield figures were in positive correlation with annual precipitation in general. Water availability had diverse influence on quality manifestation. Good water supply has often resulted in poorer grain quality, especially wet gluten and Hagberg values have been affected by that. Drought reduced the amount of yield in general, but contributed to a better quality manifestation in some of the crop years.

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.

Semiarid Conditions

The aeolian processes play an important role in the relief formation under the semiarid conditions of the intermountain basins of Southern Siberia. Ancient sand landforms occur in different regions of Siberia — the Ob, Chuya, Аley, Yenisei, Аngara, Selenga, Chikoy, Khilok and Chara river valleys and Lake Baikal coasts. The sandy coasts of Lake Baikal are of great interest in terms of floristic diversity determined by a high degree of endemism. Despite centuries of study of the lake basin, sand vegetation is poorly described in the literature. This study presents an analysis of 184 relevés of psammophytic vegetation from the Republic of Buryatia (Severobaikalsky, Barguzinsky, Pribaikalsky districts) and Irkutsk region (Olkhon Island) obtained in 2009–2014.
