Desertification-current status
According to the statement of the UN Convention for Combating Desertification that approx.70% of the total landscape of Mongolia is under treat of desertification and land degradation.

Causes of desertification
• Natural factorsNatural factors::• Changes on average air temperature (over past 70 years,
air temperature has increased by 2.1C) and fluctuation and total amount of rainfall

The world average annual air temperature has increased by 0.5-0.6C over past 100 years. Ave. annual air temperature in Mongolia has increased by 1.66C
Causes of Desertification• Man made causes: Man made causes:
• Pastureland utilization /traditional way of pasture use has been
neglected/
• Weak awareness on combating desertification among public• Exceeded current pasture capacity /pasture capacity has exceeded by
32.5% or by 16 million head of sheep. This is considered as the main cause of desertification/.
• Modification in population of livestock /total amount of goat population
has reached at 19.9 million and it occupies about 46% of the total
population of livestock/.
• Dried rivers and lakes due to mining and other human activities.
• severely affected by desert – 5.0%• heavily affected by desertification– 18.0 % • moderately affected by desertification– 26.0%• lightly affected by desertification– 23.0%Central and settlement area of 145 sub-provinces in Gobi-steppe region is under sand movement.

Government policy on combating desertification
Priority areas of National Program on Combating Desertification
Constraints and issues
• Legislation on combating desertification and economic situation is not meeting with current need and requirements.
• Strengthening and improving cross-sectoral coordination and management.
• Insufficient planning, utilization and regulation of agricultural land, which occupies over 70% of total landscape of Mongolia.
• Lack of financial sources to combat desertification. • Weak capacity at local level to combat desertification
Constraints and issues
• Immature monitoring, evaluation, reaserach and information system of desertification.
• Lack of Government incentive giving system to encourage active involvement and initiations from public, economic entities and local organizations in combating desertification
• Insufficient of introducing innovation and modern technologies in
restoration of abandoned areas and controlling sand movement.
• Weak law enforcement by the Government and public for controlling
illegal utilization of natural resources.
• Law level of public ecological education.
