Historical-Genetic Features in Rural Settlement System: A Case Study from Mogilev District (Mogilev Oblast, Belarus)

: Settlement system development is currently one of the basic objectives in land use planning, which is significant for Belarus, as it is the most urbanized country in the European region. Historical-genetic analysis is the most effective approach for studying the transformational changes in settlement systems. The research was aimed at analyzing the transformation peculiarities in the rural settlement system of Belarus. The core of the methodological basis lies in general scientific methods (systematic approach, historicism approach, historical-genetic method) and special interdisciplinary methods (cartographic analysis using GIS software). Historical-genetic analysis made it possible to identify the most significant historical periods in the formation of the rural settlement system in Belarus: pre-revolutionary, Soviet and recent. For each period, the pattern and spatial configuration of the rural settlement system were analyzed. Spatial changes in settlement pattern were highlighted: polarization, increasing the share and the population number of the “largest” settlements, the decreasing of “large” and “medium-sized” settlements and the degradation of “small” settlements. As a result, two types of rural settlement transformation were identified: “development” and “degradation”. Three ways of spatial configuration of the rural settlement system were identified: “relocation to city”, “relocation to the center of the settlement system” and “relocation to settlement”. Directions for future research are linked with conceptualizing the model of the spatial–territorial organizing of the rural settlement system.

The increasing interest in studying rural settlements in Belarus is caused by the special role of rural settlements in a spatial country development, where agricultural areas cover 1/3 of the total territory and the GDP share of agriculture is about 7%. Currently, Belarus is the most rapidly urbanizing country in the European region [43], so there is a significant impact on the rural settlement structure. It should be noted that the settlement system, due to its specific features, is sensitive to various risks, such as natural, sanitary-epidemiological, anthropogenic and management planning., as confirmed by the difference in forecast [43] (Figure 1) and estimated data ( Table 1).  Urban saturation, as an indicator of social development, is determined by the improvement of industry, cultural and political functions, which is achieved primarily in cities today [44][45][46]. One of the advantages of rural settlements in Belarus is due to its specific feature. Rural settlements have absorbed the Soviet period genetics: high standards of living were created in agro-townsmodernized centers of rural settlements, formed by converting previously existing central estates to advanced communal farms.
The main research aim was to identify the general features in transformation of the rural settlement system.

Research Area
The research area was the Mogilev district, the Mogilev oblast, which is located on the eastern side of Belarus. The total area is 1895.4 square kilometers. The administrative center of the Mogilev district is the city of Mogilev, which is administratively not a part of the district. The district is composed of 15 administrative regions (Rural Soviet). There are 276 rural settlements in the district. According to the National Statistical Committee of the Republic of Belarus the population of the district as of January 1, 2019, was 39,667 people. Figure 2 shows the location of the research area.

Historicism Approach
The following hypothesis was formulated in order to solve the research problem: according to a systematic approach, the settlement system meets the historicism principle common to all systems, and historical-genetic modeling allows both studying and forecasting the system development [33].
Historicism, as one of the principles of the system approach, involves the analysis of the system genesis and trends in its development, which is necessary for adequate system functioning. The historicism approach provides deep insight into historical processes. The application of the historicism approach is particularly justified in research detailing the formation of the settlement system. The historicism principle involves the analysis of the conditions of the settlement system formation in terms of the cooperative effect of objective and subjective factors that determine the direction and intensity of changes in the settlement pattern. The historicism approach is implemented through a set of methods (historical-genetic, historical-typological, historical-comparative) that provide the synthesis and analysis of changes in the research area. In such a case, the historicism principle can be typified as a modification of system analysis methods, focused on retrospective research [47,48].
For regional planning research, it is important to know the system genesis. The application of the historicism principle allows us to consider the settlement system in specific historical terms and clarify the spatiotemporal dynamics, such as identifying periods and evolution features of the settlement system, which reveal its current status, forecasting the advanced directions for improvement.

Historical-Genetic Method
The method basis is linked with a comprehensive analysis of settlement creation and the factors that determine the character of settlement development. The method is based on time sample research in spatial planning and includes three main stages: (1) Preliminary analysis and evaluation of the current settlement pattern. (2) Identifying the changes in regional space planning through time in various socioeconomic periods. (3) Data synthesis and data processing for each period [49].
Stage 1. Preliminary analysis and evaluation the current settlement pattern. This stage includes collecting data on the historical regional development: analyzing old maps, historical databases and statistical data. Consequently, historiographic synthesis allows the presentation of both the sequence of events/factors and the process of forming the main features of the current settlement through time. Identifying the spatiotemporal boundaries for the research area is an overall result of the first stage. Spatial boundaries are assigned by the features of land use planning and management (for example, administrative boundaries). Time boundaries are assigned by the specific features of the research object such as scale, complexity and age. Division into time periods reflects the general and most typical stages in regional planning development.
Stage 2. Identifying the changes in regional space planning. The research is conducted chronologically to identify the most stable elements and features through time/space. When researching each time period, a complex multi-factor analysis is carried out. Besides, it should be noted that historical, socioeconomic and environmental features of the research area are of equal interest. There are four main processes in the second stage: (1) Identifying the planning centers, planning lines and regions for each period. (2) Structuring the settlement system into the main and secondary elements. (3) Establishing a functional and spatial correlation between the structural elements. (4) Identifying key drivers. Thus, the main aim of the second stage is obtaining a complete historical slice for each period. The obtained historical-genetic pattern of the regional settlement comprises a block of complicated data on the research object.
Stage 3. Data synthesis and data processing. The main goals of the third stage are linking the historical slices; identifying the key drivers for the development of the settlement system; and the analysis of the changes in the settlement system. As a result, historical features and trends in the settlement processes for the research object are identified and explained. A summary historicalgenetic scheme synthesizes the accumulated data and represents data in a recent cartographic base. The scheme includes regional land zoning by the main periods; regular interconnections between the settlement elements; genetical settlement typology by spatial localization, size and hierarchy in the settlement system; historically formed functional zones and the most stable planning lines.
Consequently, stable trends and regularities in regional spatiotemporal development should be a basis for a predictive model of regional spatial organization. The three main aims are solved using the logical application of previously discussed methodological principles: (i) identifying the genetic basis of the current planning structure and its elements; (ii) the analysis of changes in planning structure within the main stages and phases and (iii) forecasting the development of the regional planning structure and its elements. Generally, a holistic vision of the optimal probabilistic development of a settlement system is provided. This method can be used for retrospective analysis within each hierarchical level of regional planning (from regions and city elements to large regional systems).

Cartographic Analysis
The analysis of changes in the spatial configuration and settlement pattern in the area of the Mogilev district has been based on the sources listed in the References, including population census data [50], maps from the years 1826-2020 [51], and the schemes of complex territorial organization (SCTO) of the Mogilev district [52]. Some of cartographic and analytical functionalities of open source GIS (Quantum GIS) were used to reach the research objective: (i) exploring data and composing maps and (ii) creating, capturing, editing, analysis and managing data.

Results and Discussion
For solving the research aim, three periods in the history of the formation of the Belarus settlement system were identified: (i) pre-revolutionary, (ii) Soviet  and (iii) recent (beyond 1991), which caused the most intense transformation of the rural settlement system. Objectively, such division is due to the political regime changes, from imperialism to socialism, and later to the new socioeconomic stage of creating Belarus as an independent state.

Identifying the Changes in Spatial Configuration and Settlement Pattern
The beginning of the pre-revolutionary period (1909) was conditioned by the stability of the existing rural settlement system and data sufficiency.
Within the pre-revolutionary period, the Mogilev district area was a part of the Mogilev Governorate and was divided between Bykhovsky, Goretsky, Mogilev and Chaussky counties. In 1913, the Mogilev county was composed of 13 volosts as centers of the regional settlement system: Belynichskaja  Figure A1 and Figure A2).
What is important to notice is that about 10% of the rural population lived in "small" (less than 100 people) and the "largest" settlements (more than 1000 people). About 1/3 of the rural population lived in "large" (from 500 to 1000 people) settlements. The largest share (almost 60% of the rural population) lived in "medium" (from 100 to 500 people) settlements. The most typical were "medium-sized" (more than 50%) and "small" settlements (about 1/3 of the total amount), while the share of "largest" and "large" was respectively 12% and 1% (Table 3, Table 4, Table 5).  Average population    Figure A3). Later, some settlements disappeared from the maps of the Mogilev county/district. Thus, the Korobanovka village disappeared, nowadays there are only two similarly named streets (Verhnjaja Karabanovka, Nizhnjaja Karabanovka). The Popovka village was located along the current Dimitrov Ave in pre-war times. The Davydovka village became a part of the Mogilev city developed during the Soviet period and is now known unofficially as "Abyssinia settlement". The Titovka village was located at the city outskirts along the Bykhov highway. Lupolovo shtetl became a part of the city as a result of the joining the similarly named district in 1931 (Appendix A. Figure A4). Urbanization was extremely intensive in BSSR in the post-war period (since the mid-1950s), due to socioeconomic, historical, natural and political influence. The fast-paced urbanization was primarily caused by lobbying for a new industrial location in BSSR along with a labor force intake. Therefore, the Grebenevo village disappeared in the beginning of the 1970s. The village territory was occupied by the largest chemical enterprise in Europe (Mogilev synthetic fiber plant), whose area was included in the city boundaries.

Average household amount
Previously, there was the Gorki individual farm and the Gorki village in the southern part of the Mogilev city. Today there is a microdistrict "Rabochij poselok". The Holmy village was previously located to the east of Mogilev and became a city area later. There was the Dubenets village to the north in pre-war times. Later, the village area became the microdistrict called "8th brick". There is a residential area of the KSI (silicate products enterprise) nowadays. Nearby there is the Solominka microdistrict, which was built on the territory of the similarly named village. The Kazimirovka microdistrict developed from 1978 to the recent period in the western part of the Mogilev city along the Minsk highway within the territory of the similarly named village. The Sputnik microdistrict located on the territory of the Gorodshchina individual farm was actively developed in the post-Soviet period (Appendix A. Figure A5).
The course of settlement consolidation and individual farm rehabilitation was taken during the stage of collectivization and communization (1920s-1930s), when more than 80 new rural settlements were formed within the current boundaries of the Mogilev district. It should be noted that the population of the district decreased in the post-war period due to military operations within the territory of BSSR. Thus, about 70% of residential buildings in 54 settlements (about 1/3 of the total amount in the district) were destroyed from 1942 to 1944, and almost 20% (10 units) were destroyed completely (Gorodok, Goryany, Dobrosnevichi, Termina, Lunise, Kurgan, Maloe Bushkovo, Nikolaivka, Stashino, Churaevka) [53].
Significant changes occurred in the settlement structure. The largest share (53%) belonged to "small" settlements with a population of 14.2%. The share of 56.5% lived in "middle" settlements (41.3%). The share of "large" ones was 4.7%, with a population of 20.5%, and the smallest group was represented by the "largest" settlements (1%) with a share of the population of 8.8% (according to the 1959 census) ( Table 4). As a result of the Chernobyl disaster, some territories of BSSR were poisoned by nuclear pollution and the relocation of the greater share of the rural population to other settlements followed. Consequently, by the end of the Soviet period (1990), the share of the "largest" settlements was 2.8%, with a population of 23.1%, "large" settlements had 4.21% and 16.1%, respectively, the share of "medium" settlements was 39.6% with a population of 48.2%. The largest group was represented by "small" settlements (53.3%) with a population of 12.6% (Figure 4).

Recent Period
During the recent period, the conurbation continued due to the annexation of rural territories. Thus, in the mid-2000s, the Malaya Borovka village and the Dary village (partially) were included in the city boundaries (Appendix A. Figure A6).
The population decreased in all settlement groups: "small"-from 12.6% in 1990 to 13 (Table 4, Figure 4). The most significant changes occurred at the beginning of the recent period and were linked with is the USSR collapse. It should be noted that the transformation of the rural settlement system reduced with the ratification of the "National plan of rural renewal and development" in 2005.
The locality network from 1909 to 2018 within the current boundaries of the Mogilev district are shown in Figure 4. The changes in the rural settlement structure from 1909 to 2018 are shown in Figure 6, Figure 7 and Figure 8. The key trend is structural polarization, the steady decreasing of "large" settlements and increasing the number of the "largest" settlements; rapidly decreasing the number of "mediumsized" settlements and increasing the number of "small" ones and the population decreasing in all settlement groups except "large" ones.

Conclusions
The current research confirmed the validity of the research hypothesis. The obtained results show the relevance of the historical aspect for the analysis of the settlement system. The conclusions are as follows: (1) The historical-genetic analysis allowed us to identify three historical periods: prerevolutionary, soviet and recent, which is significant in the formation of the rural settlement system in Belarus. It should be noted that socioeconomic, ecological and administrative aspects, such as changes in government policy, man-made and natural disasters and ongoing reforms affected the transformation of the settlement system in the research area.
(2) Structural changes in the rural settlement system in Belarus were found between 1909 and 2020. The main trend is network polarization: increasing the share of the "largest" settlements and their population, the decreasing of "large" and "medium-sized" settlements and the degradation of "small" settlements.
(3) Two sample groups of settlement transformation were identified: "development" and "degradation". There are two transformation types in the "development group": (i) The changeover to "urban settlement" is linked with population growth and industrial growth. (ii) The changeover to agro-towns is linked with population growth and agro-industrial growth. The second group, < 100 100-500 500-1000 >1000 "degradation", comprises the following transformation forms: (i) Degradation as a result of depopulation. (ii) Disappearance/absorption as a result of city/agglomeration growth. (4) Three ways of spatial configuration in the rural settlement system were identified. The first way, "relocation to city", comprises the complete/partial relocation of rural residents to the city or conurbation. The second way, "relocation to the center of the settlement system", comprises moving residents to larger/leading settlements (village council center, agro-town) or changing the settlement type. The third way, "relocation to settlement", involves moving residents to current/created settlements, which is linked with settlement elimination as a result of man-made disasters, natural disasters and ongoing reforms.
The findings of this paper can enrich the existing theoretical research on regional planning and can provide guidance for policy makers to encourage the sustainability of settlement patterns. Future research perspectives are linked with conceptualizing the model of the spatial-territorial organizing of the rural settlement system.
