Salinization and alkalization are considered spatiotemporal dynamic soil degradation processes. In order to investigate the effects of agricultural activities on land degradation and soil salinity, Shamsabad area in Qom province was selected. Aerial photos (1955) and satellite images (1990-2002) were used to examine the changes in land use. Soil samples were collected from 25 locations in the study area from 0-50 cm and 51-100 cm depth at each location. For comparative purposes, sampling locations in this study were similar to locations used for salinity study in 1983.

As market reforms to the Mongolian economy continue and the country enjoys rapid economic growth, the environment has entered a period of unprecedented pressure. Mining, infrastructure development and tourism development, in particular, are undergoing rapid expansion, and all pose risks to Mongolia's globally important biodiversity.

In the not so long history of humankind, our ancestors too often fought for land and water. Those days have returned.

En la no tan larga historia de la Humanidad, nuestros antepasados han luchado con demasiada frecuencia por la tierra y el agua. Aquellos tiempos están nuevamente de actualidad.
