Abstract: Since Mongolia's transition to a market economy in the 1990s, the “Great Migration” from rural to urban areas due to job shortages and natural disasters (droughts and dzud - disaster affecting livestock caused by severe natural conditions) in rural areas has continued. Many of these in-migrants have settled in large cities and their subur...

It is important to develop the location, type, and territorial organization of health institutions in line with the regional development, population distribution and settlement system planning in Mongolia with such small populations but large territory, abundant natural and agricultural resources, and a relatively high rate of rural to urban migrat...

The large territory, including Mongolia and Russian Siberia, discussed in the article, has similarities in physical, geographical, and socio-demographic parameters, as well as the attitude to them as "resource colonies". But these Siberian and Mongolian components differ significantly politically, which affects their institutional and managerial ch...

The commodity and geographical structure of Mongolia’s exports, dynamics and features of Mongolia’s foreign trade with Russia are considered. The tendency of weakening of foreign trade interaction of Mongolia with the Eastern regions of Russia is revealed. Using the original author’s method, an assessment of the distribution of Mongolian export goo...

When discussing the geographical features in the formation of the framework of the economy, population distribution and nature management of Russia (Siberia) and Mongolia in conditions of the landlocked location and an enhancement in Eurasian integration processes, it is necessary to capitalize primarily on the national priorities of Russia (and on...

As the pace of urbanization accelerates, the quality of life in large cities is becoming increasingly determined by the level of preservation of the components of the natural environment. One of the main ecological living-standard criteria is the quality of water resources and soils. The article analyses statistical and published materials on soil...

Abstract. The article studies the spatial and temporal dynamics of the population of urbanized areas in the neighboring territories of Siberia and Mongolia connected by transport communications. The units of observation taken for the research are urban districts and municipal districts in Russia, and the capital city and aimags in Mongolia. Officia...

Air and soil contamination in developing countries exacerbates due to poor management of waste collection and serves as a morbidity and mortality factor. This study aimed to conduct an assessment of soil pollution level in Ulaanbaatar and establish а correlation between microbial contamination and registered occurrences of contagious diarrheal dise...

In the forms of population migration in Mongolia, nomadic herders move to urban and other settlements as the most common forms of migration. Population settlement is sedentary lifestyle and the basic way of improving people's living conditions, including many socio-economic and environmental aspects. The survey was conducted in 9 provinces of Centr...

Geochemical changes in the surface soil horizons and in the trace element composition of the leaves of poplar hybrids under the influence of emissions from the industry and transport hub of the city of Darkhan (Mongolia) were studied. Based on the data of the geochemical survey, priority pollutants in various land-use zones of the city and regulari...

Report on the Asian Development Bank Technical Assistance TA-8802 project Strategic Planning for Peatlands Conservation and Wise Use in Mongolia

This paper deals with food selectivity in large herbivores of Eastern Mongolia, its factors, and their impact on the herbivore community structure. It is shown that, due to the degradation of vegetation, all stud- ied herbivores display a significant selectivity level conditioned by their morpho–physiological features and spatial distribution. The...

The aim of the present study is to evaluate geochemical transformation of soil cover in the territory of Erdenet (Mongolia) and to assess the environmental risk associated with soil cover contamination. The objectives of the present study included: (1) the determination of heavy metals (HMs) and metalloids contents in surface horizons of background...

The Mongolian gazelle (Procapra gutturosa Pallas, 1777) and five domestic herbivores share the steppe plants. The desertification of the steppe induced by overgrazing is related to the activities of the community of the large herbivore. A plant-herbivore data matrix obtained by cuticular analysis has made it possible to estimate the impact of troph...

Field observations have been used to characterize air pollution in Ulan Bator by heavy metals during the 2008/2009 heating season. The degree of technogenicity of emissions and their main sources are determined. The diurnal and seasonal dynamics of atmospheric pollution are considered. It is found that many pollutants exceed maximum permissible con...

Last years, after beginning of economic and political reforms of 1990-s, pastoral loads are gradually increasing throughout Mongolia together with intensified climatic aridization. Ecosystems of Dundgovi aimag were exposed to synergetic influence of both these factors. It intensified processes of degradation and desertification of soil-plant cover...

The paper presents detailed characteristics of the pastures and the structure of livestock over the last decades in Middle Gobi aimak of Mongolia as an example of Rashaant bug (brigade). The problems of watering places were investigated, and recommendations for optimizing the structure of populations and conservation of ecosystems for the study are...

The article deals with lead contamination of the air, snow cover, soils, and woody vegetation in Ulaanbaatar evaluated against the background concentrations and established norms (maximum permissible concentration, MPC). Strong air pollution during the period from December to March is detected. The features of the diurnal variation and average conc...

Based on the results of a biogeochemical survey, an assessment of the state of woody vegetation in the functional zones of Ulaanbaatar is given. A strong accumulation of Zn and Cd is detected in poplar leaves, with Mo and V found in larch needles. Among the factors responsible for the accumulation of microelements in poplar leaves, the main ones ar...

Based on the results of the soil-geochemical survey, the assessment of the soil cover pollution in different Ulaanbaatar functional zones is given. The soils of the industrial and traffic zones concentrating a wide spectrum of pollutants (Zn, Mo, Cr, Cr, Cd, Pb, and Cu) are characterized by the strongest technogenic transformation. The soils of the...

The research was carried out in Erdenedalai sum Dundgovi aimak, located at the distance of 350 km to south-west from Ulaanbaatar city. The polygon was chosen in band transition caused by dry steppe towards desert steppe and steppe. If the north side of the sum is dominated typically dry steppes compactly turf cereal community with cereals (Stipa kr...

Qualitative and quantitative characteristics of the technogenic anomalies of heavy metal concentrations in the soils of Ulan Bator, Darkhan and Erdenet were obtained. Background geochemical conditions of the study area and the technogenic specialization of towns were determined. Spatial geochemical diversity of urban soils due to their functional s...

This paper presents qualitative and quantitative assessment of technogenic anomalies of heavy metals in urban soils of Ulaanbaatar, Darkhan, and Erdenet (Mongolia), including the assessment of background geochemical conditions of the study area and technological specialization of the cities. The research efforts concentrated on identifying spatial...

Researches conducted in Erdenedalai sum, in the region of transition from dry steppe to desertified steppe and steppefied desert have showed development of degradation processes in ecosystems as a result of combined influence of climate aridization and overgrazing. In the soil covering it reveals in degumification, blowing up of small soil particle...
