Sustainable land management in Mongolia

M

ongolia is one of biggest inland countries in

Asia with an area of 156.65 km

2

, most of which

is arid and semi-arid land. It lies at a fairly

high elevation (approximately 1,580 m) above sea level,

completely separated from oceans and seas (500 km from

the Atlantic Ocean, 1,600 km from the Yellow Sea) and

surrounded by high mountain ranges. It borders on China

in the east, west and south and on Russia in the north.

According to the definition provided in the United Nations

Convention to Combat Desertification (UNCCD), 90 per

cent of Mongolia’s landmass is highly vulnerable to deser-

tification and land degradation.

Mongolia has a typical continental climate and average

temperature of 1.56a. The lowest temperature is -50

0

C in

winter and in the Gobi area the highest temperature can

reach 40

0

C. The topography of the land largely influences the

geographical distribution of climate characteristics, and is to

some degree reflected in the soil and vegetative cover proper-

ties where it has created a distinctive distribution pattern. On

the other hand, Mongolia has one of the region’s most arid

climates and its ratio of precipitation to evapotranspiration

fluctuates in most territories between 0.05 and 0.65, therefore

it is highly vulnerable to desertification.

The main characteristics of Mongolia’s climate are its distinc-

tive four seasons, high fluctuations in air temperature, low

precipitation, and notable climate differences in latitude and

altitude zones. Results from continuous studies based on offi-

cial data from the National Meteorological and Hydrological

Observation Network demonstrate that the mean annual air

temperature in the Altai, Khangai, Khentii and Khovsgol moun-

tainous regions is colder than 40

0

C, while the valleys between

mountains and major river valleys are colder than 6-8

0

C, the

desert steppe zone is warmer than 2

0

C, and southern Gobi is

warmer than 6

0

C. The mean annual air temperature corre-

sponds with the northern edge of Mongolia’s desert steppe

zone, at latitude approximately 46° north. Permafrost occurs at

territories with a mean annual air temperature lower than -2

0

C.
