The paper presents the analytical survey of scientific works of the researchers of All-Russia Research and Development Institute of Land and Forest Improvement dealing with the aspects of changing climate. The possible reasons of climatic global changes, factors influencing the landscapes transformation, the role of protective afforestation within the system of measures for the adaptation of agricultural production to the unfavourable climatic conditions are discussed. Carbon sequestration in vegetation cover and in soil is the most important factor for regulation of gas pollution in the atmosphere. The amount of carbon fixed by trees in different farming systems ranges from 3 to 25 tons per hectare and sometimes reaches 60 tons per hectare. The young intensively growing forestations are the most carbon-absorbing ones. The ploughing of virgin and laylands resulted in the transformation of landscapes on the territory of Russia. The area from forest steppe to dry steppe zone is currently represented by agrolandscapes with tilled chernozem soils amounting up to 75-90%. Under the circumstances, the global climatic changes promote further degradation of ecosystems and decrease of their variability. The growing aridity of climate, weather extremes of last years complicate the development of the problem to obtain high and stable productivity of agricultural crops. The forest belts growing in agrolandscapes counteract effectively the unfavourable climatic conditio
ns. They are a component in a system of measures aimed on growth of productivity of agricultural crops and soil fertility, and protection of acreages from droughts and dry winds, and soil conservation from water and wind erosion. The field protective windbreaks affect climate mostly in comparison to other types of forestations. The interaction of forestations within the common network is the main element for spatial arrangement of the agrarian ecosystem.
