“…Land use changes in Ulaanbaatar have been analyzed at the metropolitan scale using MODIS, Landsat, and SPOT imagery in some previous studies (Amarsaikhan, Blotevogel, Ganzorig, & Moon, 2009;Tsutsumida et al, 2013). However, residential-scale land use changes, which can depict urban expansion more precisely, have not been investigated in detail to date owing to the lack of time series of feature-oriented data reflecting urban components.…”

a b s t r a c tBecause of the lack of time-series spatial data on urban components, urban expansion in developing countries has usually been studied using a pixel-based approach, despite the coarse spatial resolution associated with this technique. To understand the residential-scale processes involved in urban expansion, we developed feature-oriented GIS data extracted from very high spatial resolution satellite images (IKONOS for 2000 and Quickbird for 2006 and 2008). We selected a fringe area of Ulaanbaatar, the capital municipality of Mongolia, as a case study. Residential plots in this area have developed in an unplanned manner owing to the poor execution of land reform policy. This study facilitated the residential-scale delineation of the significantly expanding area occupied by private land plots in time series. It also permitted the identification of geographical factors driving the expansion. Using a logistic regression model, we found that such expansion is related to social infrastructure rather than to natural landforms. In particular, new plots of private land tended to be built near pre-existing plots and in proximity to roads and water kiosks (which provide essential drinking water for residents). These findings and the probability map predicted by the model have implications for urban planners and decision makers.

“…Ulaanbaatar today is the main political, economic, business, scientific and cultural center of the country. In addition, the city is home to the central government and its bureaucratic structure, and the most prominent public and private institutions of higher learning and best medical services (Amarsaikhan et al, 2013). Figure 1 shows recent outlook of the test area in the Landsat TM satellite image and some examples of its land cover.…”

At present, air pollution has become the main problem in many developed and developing countries. Especially, in Ulaanbaatar city of Mongolia, it has become one of the most tackled issues of every citizen living in the capital city. The aim of this study is to highlight the trend of air pollution and pollution sources in the Mongolian capital and conduct some air pollution analyses. Overall, the study indicates that the air pollution in Ulaanbaatar city is a very serious problem and for its reduction, rapid and thorough measures should be taken.

“…Some previous studies have used aerial photography for their analysis (Amarsaikhan et al 2009;Tsutsumida 2013). In an analysis of aerial photographs from 2000, 2006and 2008, Tsutsumida (2013 identified and counted the number of Kha-shaa and Ger one-by-one using geographic information systems (GIS), which clarified the extent of outward expansion of Ger areas.…”

The suburban area of Ulaanbaatar, the capital city of Mongolia, has an extensive "Ger area" where residents live in Ger or Bai-shin. Recently, Ger areas have reportedly expanded in accordance with the increasing population. Previous studies of Ger areas have tended to focus on the "unique sight" of Gers in the city and few have discussed the residents' point of view. For this study, the two analyses focus on and clarify the changes in Ger areas over time, using aerial photographs, first to clarify Ger areas' expansion, the regions that corresponded either to "Ger areas, " consisting of continuous Kha-shaas, or "Apartment areas, " consisting of apartments or modern buildings, which were marked by lines. The second is to clarify the internal changes in Kha-shaas, and identify individual Kha-shaa, Ger and Bai-shin within each Kha-shaa marked at three selected sites. In addition, Kha-shaa were counted and categorized according to whether they contained "Ger only", "Ger and Bai-shin", or "Bai-shin only. " Through these analyses the clarified Ger areas were understood to be redeveloped for apartments in the socialist era but after democratization the promised development did not take place. Old Kha-shaa consisted of "Bai-shin only" or "Ger and Bai-shin", and new Kha-shaa consisted of "Ger only". In other words, Ger have been gradually decreasing because of the building of Bai-shin, which are more comfortable and convenient for urban living. Although progressively more Bai-shin are being built over time, Ger do not disappear because they are being used for different purposes by residents. Those who relocate to Ulaanbaatar rely on family members who live in Ger areas for temporary accommodation in their Ger. "Gers in the city" not only means a unique sight but also living in a Ger is very rational in urban life.
