soils in Tajikistan

The basic theses:
•
•
•
•
Change of temperature of air;
Change of deposits;
Change of snow stocks;
Degradation and soil desertification
• Tajikistan ratified the Frame
Convention of the United Nations on
climate change in 1998, having taken
up obligations as the Convention
Party
• Tajikistan ratified the Kiot Report in
2008
•
In Tajikistan the legislative and institutional basis for
the actions directed on the decision of problems,
connected with climate change is created.
•
The official body on hydrometeorology of Committee
of preservation of the environment at Government
republic Tajikistan co-ordinates actions for climate
change in Tajikistan.
•
For these purposes in 2004 the Center on climate
change studying which competence includes realization
of corresponding projects, planning of a uniform policy
and participation in the international negotiations on
change questions to has been created

Owing to global warming many small glaciers
Tajikistan have completely thawed

Condition and estimation struggle
against desertification
• Degradation of the earths has captured
nearby 97, 9 %
• In comparison of 1973 on 30 % it is more
• Annually about 50 thousand in hectare of
the cultivated earths are exposed to
various degree of desertification.
Desertification factors
•
•
•
•
•
•
Lay of land
Environmental conditions
Rocks
Vegetative cover
Soil cover
Anthropogenous factors
Desertification processes
•
•
•
•
•
Water erosion
Ravine erosion
Secondary salification
Raising of level of ground waters
Wind erosion
Anthropogenous factors
•
•
•
•
•
•
Development of abrupt slopes
Wrong watering
Wrong placing of agricultural cultures
Cutting down of woods
Pasture cattle
Wrong placing of hydraulic engineering
constructions
Recommendations and decision ways
• To give more scientific and state blow
attention to monitoring of indicators of
climate change
• To take and expand a network of
especially-protected natural territories to
develop transboundary ecological
corridors and cooperation with
neighbouring countries and other states
• Increase of fire-prevention protection of woods and their
protection against wreckers and the illnesses, added
with increase in volume of restoration of woods and
strengthening of a network protected
• Regulation of water-physical properties for reduction of a
soil drought in the conditions of climate change of soils
• Optimisation of irrigation norms of agricultural crops in a
combination to application of methods of overhead
irrigation and a drop irrigation in the conditions of a
drought and deficiency of water resources
• Creation of information system on desertification
problems
• The organisation of monitoring of process of global
warming and desertification
• Improvement of methods of struggle against degradation
of soils
• Raising of a role of the international cooperation in
struggle against global warming and desertification
• Raising of a role of local population, non-governmental
the organisations on struggle against desertification
Thank you for attention
