Mongolian economic history is rooted in agriculture and livestock herding. The country's nomads raise and herd livestock and usually move approximately every three months in order to adapt to often unforgiving weather.
Even the global credit crunch has impacted Mongolia's nomad population. A 2009 Wall Street Journal story explored how a drop in demand for cashmere among recession-hit shoppers caused financial woes for some farmers, including loan defaults.
Getty photographer Aletheia Casey recently documented Mongolian nomadic life and the cultural pressures that are changing some of those traditions. Hear more from Casey in the slide show above.
