Water erosion in the Southern Ural steppes

Ecological-hydrological analysis of erosion processes on the key watersheds of Southern Ural steppe was used to determine the surface runoff as a function of the physico-geographic and anthropogenic conditions, i.e., snow storage and soil moisture reserves before winter, whose contribution reaches 68–81%. The rate of humus losses in chernozems and dark chestnut soils was calculated for different periods in accordance with erosion stress and the extent of the economic development of the territory. Agroecological types of arable lands with different surface runoff characteristics, rates of natural soil formation, and erosionrelated soil losses are identified. Measures aimed to reduce humus losses in soils are proposed. Relationships between the rates of soil formation and erosion losses are proposed to be used as ecological-hydrological criterion (index) of soil stability.

Dynamics of forest fires and climate in Ilmen nature reserve, 1948–2013

This paper considers the impact of climatic factors on the forest fire rate in Ilmen State Reserve based on 66 years of direct observation data for 1948–2013. This period was marked by a gradual annual increase in the number of recorded fires in the reserve. The higher fire rate is generally related to lengthening of the fire season and more frequent fires in the spring and summer–early autumn periods. We did not obtain sufficient evidence to verify a relation of the higher fire rate to climate changes. The average monthly and seasonal weather conditions can be involved to explain only some causes of the interannual fire rate variability. The observed changes in some climatic characteristics could have contributed to an increase in the fire rate, while others could have reduced it.

Problems of dependable water use in the transboundary Ural River basin

The regional specifics of water use in the transboundary basin of the Ural R. are studied. The diverse problems of dependable water use in the region are caused by the interaction of natural and anthropogenic factors. Considering the space and time variations of river runoff, a possible approach to solving water use problem is runoff regulation. To effectively solve the problem of water use requires the search for an organizational and legal form of institutional interaction within the transboundary basin of the Ural R.
