The use of agricultural lands: livestock husbandry and crop production

The agricultural production is one of the leading sectors of the economic complex of Mongolia. Two branches are traditionally presented in the structure of the gross agricultural production; they are livestock husbandry and crop production. A specific feature of Mongolia is the predominance of livestock products and reliance on the pasture management system. On a national scale, the agriculture of the Baikal region of the Russian Federation holds a modest place: less than 1% of agricultural production. In the East Siberian economic region Irkutsk oblast ranks second in the production of agricultural products after Krasnoyarsk krai; the Republic of Buryatia and Zabaikalsky krai rank third and fourth, respectively. Among the regions, included into the Siberian Federal District, Irkutsk oblast, the Republic of Buryatia, and Zabaikalsky krai rank 5th, 8th and 9thin the agricultural production, respectively. In the economy of Irkutsk oblast the agriculture plays a minor role. Its aim is to meet the needs of the local population in agricultural products. In Zabaikalsky krai and the Republic of Buryatia the agriculture is one of the leading production branches, which plays a key role in the livelihood of the population. The branch accounts for about 8.1% of the gross regional product in Irkutsk oblast, 12% - in Zabaikalsky krai, and 11.5% - in the Republic of Buryatia.

The agriculture develops under extreme environmental conditions: the agricultural territory belongs mainly to an area of ​​low biological activity, andits significant part is characterized by cold climate. Bioclimatic potential of the agricultural zone is 2-2.5 times lower than in the European agricultural zone. Consequently, to get a unit of agricultural production in the region requires more energy expenditures.

The agriculture of regions within the Lake Baikal basin includes two major branches, namely: livestock hus band dry and crop production, the shares of which in the gross agricultural output vary regionally: in Irkutsk oblast they are approximately equal; in Zabaikalsky krai, the Republic of Buryatia and Mongolia the leading branch of agriculture is livestock husbandry, the proportion of which is over 70%.

Areas of agricultural lands, which are in use by commercial farm units, engaged in the agricultural production, decrease year by year. Disposal of agricultural lands from agriculture is registered in almost all districts of the region. The main reason for the reduction of lands dedicated to agricultural production is the termination of activities of enterprises and organizations, and peasant farms. Another reason is the expiration of the agricultural tenancy (or temporary use) and its non-renewal by agricultural producers.

About 1% of agricultural lands of Russia are located within the Baikal region. The main agricultural lands are located in the forest-steppe areas and along river valleys. However, the provision of the population with agricultural lands per capita is sufficient, for example, in Irkutsk oblastit amounts to 1.1 ha, and in Zabaikalsky krai it is 6 ha (average provision index for Russia is 1.5 ha). In the total area of agricultural lands of Irkutsk oblast the share of arable lands accounts for 69%, the proportion of pastures is 20%, and meadows and hayfields cover 10%. In Zabaikalsky krai the largest areas are occupied by forage lands, meadows and hayfields, the proportion of which exceeds 80%. In the structure of agricultural lands of the Republic of Buryatia the share of arable lands is 30%. Sown lands are used mainly for cereal crops (more than 75%), among which wheat occupies more than 45%. The yield of cereals on the average is low (8-9 centners per ha), but in some farms it can reach up to 20 and more centners per ha. Potatoes and vegetables are widely cultivated for one’s own needs. Sown lands under these crops amount to slightly more than 8%, of them under vegetables is 1.0%. Vegetable production is concentrated mainly around cities and settlements. In Irkutsk oblast in the Baikal natural territory lands of four districts, namely, Irkutsky, Shelekhovsky, Slyudyansky and Olkhonsky, are involved into the agricultural exploitation. Furthermore, two districts –Olkhonsky and Irkutsky – are typically “agricultural”, where agriculture is one of the leading sectors of the economic complex. In contrast to the Irkutsky and Olkhonsky districts, in the Sludyansky district the scarcity of land resources does not allow to develop agricultural production, but the district has formed a high-intensity horticultural sector with commercial cultivation of strawberries. Currently, this resource is not included in the turnover of the legal economy of the district; it is not processed on a commercial scale, and it is realized by private buyers, who do not pay taxes. Processing of local horticultural resources is included in the plan of the production diversification in the town of Baikalsk within the framework of the program of the Baikalsk Pulp and Paper Mill conversion. In Mongolia, the total sown areas of ​​cereal crops and potatoes amount to 283.6 thousand ha and 13.6 thousand ha, respectively. Currently, the leaders in the production of cereals and potatoes are the Selenge and Bulgan aimaks.

In the structure of the gross agricultural output a quintessential role belongs to the livestock husbandry. The development of the livestock husbandry, especially sheep and beef cattle breeding, is facilitated by the presence of large areas of dry grazing lands, where valuable forage herbs grow, and by a thin snow cover in winter, enabling year-round cattle grazing along with relatively small quantities of fodder procured for winter. In the structure of the fodder base for all species the proportion of natural coarse and green forage accounts for 75 to 85% of all fodder. The foundation stock of farm animals is managed in the private sector. The livestock husbandry is represented by various branches; in the forest area of the region it is dairy-meat farming, and in the south, including Mongolia, it is distant-pasture beef-dairy and beef cattle breeding, meat-wool sheep breeding, and horse and pig husbandry. Moreover, goat breeding is traditionally represented in the aimaks of Mongolia, and camel husbandry is an auxiliary branch. Most farms produce milk and beef, implementing the so-called full cycle of a herd based on internal specialization of farms, producing milk and breeding young-stock.

Culture. Education

Education and culture are important parameters of the quality of life of population in particular areas. To some extent, they characterize the standard of life and “spiritual environment”. The main source of information for creating these maps included official statistical data for 2012 (in some cases for 2011). Materials of the Russian Federal State Statistics Service and Mongolian statistical yearbooks were also used in this work.

Cultural establishments

Cultural establishments are keepers and successors of the historical and cultural memory of the people, as well as mediators in its transfer to the next generations. Usually, cultural establishments include libraries, museums, theaters, clubs, cultural centers, cinemas, leisure centers, and cultural complexes.

In the Baikal basin, there are about 1,770 cultural establishments. The total number of cultural-and-leisure centers in this region is 875. There are 720 libraries, 106 museums, 30 theaters, 36 cinemas, and 4 circuses. In the Russian part of the basin, there are 247 children’s music, art, and dance schools. Each administrative district has cultural-and-leisure centers (clubs) and libraries. Most of the districts also have museums.

Cultural life is most vividly represented in the major cities of Ulaanbaatar, Irkutsk, Chita, and Ulan-Ude. There are famous theaters, museums, circuses, large libraries, and cinemas.

Museums serve as the main tool of memory materialization. Often, they focus on local history and ethnography. Museums give tourists information emphasizing the originality and specificity of a particular place, its nature, history, and culture. Thematically, museums of regional centers (Ulaanbaatar, Irkutsk, Ulan-Ude, and Chita) are quite diverse. In the Irkutsk part of the basin, the most valuable collections are kept at the oldest museums, such as the V. P. Sukachev Museum of Art, Irkutsk Museum of Regional Studies, Taltsy Museum of Wooden Architecture and Ethnography, Historical and Memorial Museum of Decembrists, and Baikal Museum of the Irkutsk Scientific Center SB RAS in Listvyanka. Among the largest museums in the Republic of Buryatia are the Sampilov Museum of Fine Arts, Museum of Natural History of Buryatia, and Ethnographic Museum (all in Ulan-Ude), as well as the Kyakhta Museum of Regional Studies. The prevailing type of museums in Zabaikalsky krai are historical museums of regional studies illustrating the rich history of the region’s development and the life of Decembrists and other exiles. The State Central Museum of Mongolia holds a comprehensive and unique collection of artifacts offering an opportunity to learn about the country’s natural history.

Theatrical life in the region is represented by a number of establishments. There are the Okhlopkov Academic Drama Theatre, Zagursky Musical Theatre, Puppet Theatre “Aistenok”, Vampilov Youth Theatre, and Children’s Circus in Irkutsk. In the Republic of Buryatia, there are the Buryat State Academic Opera and Ballet Theatre, steeped in tradition Khotsa Namsaraev Buryat State Academic Drama Theatre, and Nikolay Bestuzhev State Russian Drama Theatre, which is the oldest theatre company in the Republic. In Buryatia, there are also avant-garde theaters, namely, the Ulan-Ude Youth Theatre-Studio and Theatre-Studio of Modern Body Movement and Pantomime “AzArt”. There are also Buryat State Philharmonic, song and dance ensemble “Baikal”, state theatre of folk dance “Badma-Seseg”, and Puppet Theatre “Uliger”. In Chita, there are the Zabaikalsky Regional Drama Theatre and Zabaikalsky Puppet Theater “Tridevyatoe Tsarstvo” (“Far Away Kingdom”). Famous Mongolian theatres include the State Academic Opera and Ballet Theatre and Mongolian State Drama Theater (D. Natsagdorzh State Drama Theatre). The Mongolian circus has existed for more than 60 years and is the “Brand of Mongolia”. It has a circus school.

Libraries collect books and other publications and specifically process them. They also promote and organize mass campaigns with readers. Libraries have different specializations and subject matters. There are libraries of the Ministry of Culture, schools, universities and colleges, departmental libraries, and so on. In Irkutsk, there is the I. I. Molchanov-Sibirsky Irkutsk State Universal Scientific Library, which has been serving readers of the Angara region since 1861. In Ulan-Ude, there is the National Library of Buryatia, which is a modern informational institution. In Chita, there is the A. S. Pushkin Zabaikalsky Regional Universal Scientific Library. In Ulaanbaatar, there is the State Public Library of Mongolia. Its collections include the smallest Buddhist sutra in the country “The Story of the Green Tara”.

Cinemas are designed to entertain the population. Modern cinemas also perform different forms of leisure functions. In Irkutsk, Ulaanbaatar, Ulan-Ude, and Chita, there are 15, 6, 5, and 4 cinemas, respectively.

Currents

The main cause of currents during the ice free period is the wind. Depending on changes of the wind velocities, wind (drift) currents intensify in May, subside in June-August and again intensify in autumn reaching its maximum in December. Wind-induced currents take place during strong winds, when the surface waters are transferred, thus causing the water level decrease by 10 cm. In summer and autumn, the negative water setout lasts approximately 40 h, and in winter about 35 h, whereas the wind setup continues 44 and 40 h, respectively. Average negative water setout height (decrease of the level near the windward shore) is 9-11 cm, and that of wind setup (increase of the level near leeward shore) is 7-8 cm. Moreover, geostrophic currents are formed at Lake Baikal, which are stationary currents retaining their main characteristics (location, direction and velocity) for a long period of time. They are induced by the difference in temperature (density) of coastal and lacustrine waters, deflecting force of the Earth’s rotation and other factors. These currents covering both the entire Lake Baikal and separate basins are observed throughout the whole year.

Water is transferred counter-clockwise (cyclonic circulation) under the deflecting force of the Earth’s rotation (Coriolis force). Secondary cyclonic circulations are observed in separate basins. The water at the interface of neighbouring cyclonic circulations is transferred across the lake (in Listvennichny Bay, the Selenga delta, Academichesky Ridge and Cape Kotelnikovsky). The same direction of water transfer is also observed in deep water layers of the lake.

The highest current velocities are recorded in the upper lake layers – in the epilimnion and sometimes below the thermocline. Their average velocities are up to tens of centimetres per second intensifying from summer to autumn. Maximal velocity registered near the surface can be over 1 m/sec. In winter, when the whole lake is covered with ice, the vertical structure of the velocity field is usually the same, although because of the ice cover the currents attenuate significantly. Their average velocity in the upper layers (up to 40-50 m) can be 2 cm/s and lower during “calm” periods. However, it can increase up to 3-5 cm/s and even to 10 cm/s during atmospheric pressure drop in case of atmospheric fronts. General character of water mass transfer corresponds to cyclonic circulation (Fig. 2.33) in the water column.

In the 1960-s, V. Sokolnikov [1964], working on the lake ice, discovered the effect of current intensification in the near-bottom layer at large depths of the lake, which was later observed in other seasons of the year. The studies of this phenomenon carried out by V. Verbolov [1996] and A. Zhdanov [2006] showed that the velocities in the near-bottom layer are seasonal. In winter, they episodically exceed 10 cm/s and in summer (July-early August) they are 4-8 cm/s during weak winds. In spring (May) and autumn (October-November) they become an order of magnitude at seasonal increase of the wind with the values corresponding to those in the upper 200-m layer (up to tens of centimetres per second). Usually current velocities decrease in the near-bottom layer with the distance from the foot of the underwater slope, their highest values being recorded at the bottom.
