Previous IOM studies have found that a combination of complex effects, including land degradation and climate change, are altering traditional livelihood patterns in Mongolia. In a context of increased frequency of droughts and dzuds, the lack of job opportunities, inadequate living conditions, and the dependency of the rural population on livestocks have reduced the rural population's ability to earn a living. At the same time, this situation increased migration to urban areas and other aimags in unprecedented and unexplored ways. These emerging migration patterns created a large discrepancy between census data, registration data, and actual number of people living in the various baghs in Mongolia. With this study, DTM and National Statistics Office (NSO) intend to use the Mobility Tracking (MT) methodology of the DTM toolbox to track a more accurate number of people living in the various baghs in Umnugovi aimags.
