To assess the ecological and geochemical state of the anthropogenic landscapes of the Kursk region, the natural landscapes of the Kursk Biosphere Station (KBS) have been used as background for many years. However, in the absence of river and groundwater runoff, the KBS plain landscapes receive pollutants with air migration, in which transboundary transport and the influence of local pollution sources play the main role. In this regard, over the past 5 years, geochemical monitoring of the snow and soil cover has been carried out on the KBS territory to assess the content of chemical elements in it, and thereby confirm the status of the KBS natural landscapes as background. Geochemical studies of 2013-2019 showed that during this period, as a result of emissions from enterprises of the southern industrial region of Kursk, an increase in Pb concentrations is observed in the snow of the KBS landscapes by a factor of 29; Cd, Zn, Co, Sn, respectively, 13, 9, 6, 5 times; Nb, Cr, B, V, Ni - 2-4 times. The regional and transboundary transfer of air masses is associated with the constant supply of Be to the snow cover, the positive dynamics of Zr, Ag, W. At the same time, the anthropogenic impact on the KBS landscapes over the past 5 years has not led to a change in the natural content of chemical elements in chernozem soils. The natural landscapes of the KBS in terms of the content of heavy metals in soils can function as background landscapes.
Ongoing transition of the most developed countries to inclusive green growth make new demands to information-analytical provision of environment protection activities. The article shows that in conditions of appearance of new critical technologies delays in changes of statistical and departmental accounting causes occurence of "black swans" in measuring relations within the system "Society - Nature". The most critical task - development of a system of green growth indicators on the basis of methodology of environment-economic accounting.
The dynamics of the dates of the onset of phenological events such as the arrival of starlings (Sturnus vulgaris L.), the first cuckoo song (Cuculus canorus), the appearance of the first birch leaves (Betula verrucosa Ehrh.), the bird cherry (Padus racemosa Lam.) and the very early flowering of the rowan (Sorbus aucuparia L.) allows us to conclude that there is an increasing trend in the duration of spring, while the duration of the fall season for the period from 1967 to 2010 is practically unchanged. For the beginning of bird cherry flowering, the offset of the trend to earlier dates is more typical for the forest and forest-steppe territories of the Russian Plain, what suggests the connection between climatic parameters. For the appearance of the first birch leaves, the multi-directional trends of the offset of dates is obvious and revealed no dependence on natural conditions and physiographical position. The advanced arrival of starlings and the start of cuckoo song cannot be used as reliable indicators. No reaction to the unique weather conditions was demonstrated by birds. It is possible that the mechanisms of migration of birds are more likely caused by the presence or absence of prey and endogenous biological rhythms.
The state policy on stimulation of development innovative clusters at regional level is considered. By the analysis of experience of realisation кластерных initiatives in various regions, the basic directions of assistance to their development, public authorities and local government are established. The basic reference points of the state policy aimed at creation clusters are defined. The technique of identification innovative territorial clusters is proved.
