A special feature of Y. pseudotuberculosis strains is its biochemical uniformity irrespective of the time and location of the causative agent isolation and the existence of 21 serological variants. Y. enterocolitica is a quite a heterogeneous species and is classified into 6 biochemical types associated with 29 serological variants. 221 Y. pseudotuberculosis and 447 Y. enterocolitica strains in total isolated in Siberia and in the Far East were characterized. Y. pseudotuberculosis genotype dominating in the Siberian and Far Eastern regions is presented by О:1b serotype of the first genogroup (pYV+, ympA+, HPI-) in two- (47:82 МDа) or single-plasmid (47 МDа) variants. Ribotyping and fingerprinting revealed 8 and 10 Y. pseudotuberculosis genotypes, respectively, that indicated relative heterogeneity of the circulated strains. Regional difference of ribotypes and fingerprints was noted. 401 of 447 Y. enterocolitica strains were classified as biotype A1 including 11 serotypes (O:4,32; O:4,44; O:5; O:6,30; O:6,31; O;7,8; O:12,25; O:13,7; O:19,8; O:41,43) and 46 strains belonged to biotypes 2–4 of O:3 and O:9 serotypes. Y. enterocolitica strains of biotypes 1A were isolated both from the environments, animals and patient samples as like the representatives of biotypes 2–4. The differentiating tests of fucose and sorbose made it possible to identify two species new for the Russian Federation – Y. mollaretii and Y. bercovierii. Y. enterocolitica biotypes 2–4 carried pYV plasmid and chromosomal ail, ystA virulence genes. These strains were referred to phagotypes Х3 (2/O:9) and VIII (4/O:3) and also to phagotype Xz (3/O:3), unique for Russia. Y. enterocolitica biotype 1A containing ystB thermostable toxin gene was confirmed to be an infectious etiological agent.

The pre-emptive right to purchase and sell agricultural land by the authorities of the constituent entities of the Russian Federation, the maximum size of agricultural land plots, the allocation of shares among rural residents and some other features of agricultural legislation are restrictions on the realization of the right of rural residents to own land. The lack of adequate infrastructure in rural areas, especially in the Far East that fall under the Far Eastern Hectare project, is also seen as an obstacle for rural residents to exercise their right to land.

Pseudotuberculosis in humans until the 1950s was found in different countries of the world as a rare sporadic disease that occurred in the form of acute appendicitis and mesenteric lymphadenitis. In Russia and Japan, the Yersinia pseudotuberculosis (Y. pseudotuberculosis) infection often causes outbreaks of the disease with serious systemic inflammatory symptoms, and this variant of the disease has been known since 1959 as Far Eastern Scarlet-like Fever (FESLF). Russian researchers have proven that the FESLF pathogen is associated with a concrete clonal line of Y. pseudotuberculosis, characterized by a specific plasmid profile (pVM82, pYV 48 MDa), sequence (2ST) and yadA gene allele (1st allele). This review summarized the most important achievements in the study of FESLF since its discovery in the Far East. It has been established that the FESLF causative agent is characterized by a unique phenomenon of psychrophilicity, which consists of its ability to reproduce in the environment with its biologically low and variable temperature (4–12 °C), at which the pathogen multiplies and accumulates while maintaining or increasing its virulence, which ensures the emergence and development of the epidemic process. The key genetic and biochemical mechanisms of Y. pseudotuberculosis adaptation to changing environmental conditions were characterized, and the morphological manifestations of the adaptive variability of these bacteria in different conditions of their habitat were revealed. The main features of the pathogenesis and morphogenesis of FESLF, including those associated with the Y. pseudotuberculosis toxigenicity, were presented. The pathogenetic value of the plasmid PVM82, found only in the FESLF pathogen, was shown.

For almost three decades, the problem of the annual decline in the demographic potential of the Russian Far East has not lost its relevance. Joining the list of Russia's national priorities in the 21st century and the active state policy pursued in this regard for the accelerated development of the largest macro-region in the country did not lead to positive changes in the demographic trend. Despite different kinds of preferences for the potential Far-Easterners, their number does not cover the number of people leaving the Far East. The article analyzes the indicators characterizing the change in the demographic potential of the Far-Eastern federal district in the context of the constituent entities of the Russian Federation for a five-year period of an active policy of socio-economic development of the macro-region. The main components of natural movement of the population are considered. It is shown that the Russian Far East is characterized by the all-Russian tendency of a decline in the birth rate, caused by the deformation of the age composition of the population, primarily women of fertile age, changes in the intensity of fertility and its age profile. While comparable to the all-Russian general coefficient, the Far East is characterized by an increased mortality rate among the population of working age. Moreover, during the analyzed period, the gap between the average Russian and Far-Eastern mortality rate of the working-age population is growing for most causes of mortality. The high mortality rate of the working-age population is the main factor in the low life expectancy of the Far East. Comparison of real and predicted estimates of demographic potential established in the Concept of demographic policy of the Far East and the Decrees of the President of the Russian Federation is carried out. As a result, it was found that expectations of the future demographic potential of the Far East laid down in the documents significantly exceed the real demographic capabilities of macro-region and will most likely remain unrealizable.

The interim results of the implementation of the new economic policy in relation to the Russian Far East are considered. A comparison is made of the macroeconomic and social results of the functioning of the Far Eastern economy during the period of implementation of the policy region (2015–2020) with the results recorded in the previous period of 2010–2014. The paper analyzes the report of the Ministry of Economic Development of the Far East and the Arctic of the Russian Federation on the results of the economic and social development of the region in 2020, which assesses the effectiveness of the new economic policy. An assessment of the ministry’s conclusions on achieving goals for the two main blocks of state policy implementation is offered – the formation of a stable trend of outstripping economic growth and the consolidation of the population in the region. It is shown that, within the framework of both blocks, no stable trends have been formed so far, corresponding to the quantitative parameters of the state priority in relation to the Far Eastern macroregion

The article deals with the prospects of development of copper-porphyry deposits discovered within the largest ore occurrences and prospecting areas of the Russian Far East. Revaluation of large reserves of copper with associated elements account (gold, silver, molybdenum) on geological data based increases the economic justification for the development of already discovered deposits, as well as the continuation of exploration work on the identified ore occurrences. Geological exploration in a certain sequence necessitates the preparation of complex prospecting, appraisal and multifactor models for the development of large copperporphyry deposits in the Far Eastern region of the Russian Federation. Complex models of geological objects for prospecting and searches of complex copper-porphyry deposits are formed in relation to each geological and industrial type. In the article, authors offer exploration typical models to develop of complex copper-porphyry deposits at different stages of geological survey. The models show the features of the deep structure of the geological objects of the simulated class and the main features of their ore-metasomatic and geochemical zoning, as well as trends in the composition and physical properties of ore-controlling geological bodies with depth. Authors present the theoretical basis of prospecting and appraisal features, reflecting the patterns of manifestation of the studied ore-bearing areas in the Far East, Russia, leads the analysis the complex of geological and geophysical studies of the deep structure of copper-porphyry deposits, formulates methodical approaches for develop modelling of copper-porphyry type fields to increase an efficiency of a geological and economic assessment of these geological objects. These approaches make it possible to comprehensively assess the parameters of exploration and development of deposits, taking into account the export-oriented orientation and investment attractiveness of the Far Eastern region of Russia.

An analysis was carried out and an assessment was taken to perform the parameters of the State Program of the Russian Federation «Socio-Economic Development of the Far Eastern Federal District». The quantitative indicators of institutional formats are shown in the absence of significant changes in macroeconomic and demographic dynamics. There is a decrease in the attractiveness of the Far East in the field of high incomes as a result of a reduction in real incomes of the population in most regions of the Far Eastern Federal District. The process of reducing the number of population is noted both by migration outflow and as a result of natural loss. It is concluded that one of the reasons for non-compliance with the basic program macroeconomic indicators is the vague formulation of target criteria
