Opis:
Since the commencement of political system transformations in Poland the number of farms keeping cows and the stock of milk cows has been decreasing very fast. A basic factor behind the regional diversity of the process is the scale of agrarian fragmentation and the size of farms. This hypothesis was verified by analyzing changes affecting cows bred in a sector of farms operated by natural persons (private farms) in the entire country and in two regions where private farms predominated. The first region is the south-eastern region characterized by a very unfavorable acreage structure of farms while the other one is the central and eastern region where the structure of farms is relatively favorable. Research results clearly indicate that, due to increasing market competition, cow breeding is concentrated and has been moving to higher and higher acreage groups. As a result, strong stock regress has been observed in the region with fragmented agriculture and such trend has been on the increase. However, in the area characterized by the favorable farm structure such regress which marked the commencement of the political system transformations was relatively quickly slowed down; already in the period preceding Poland’s accession to the UE the stock quantity and quality growth emerged which can also be seen during the post-accession era.
W Polsce, poczynając od momentu rozpoczęcia przemian systemowych, w bardzo szybkim tempie zmniejsza się liczba gospodarstw utrzymujących krowy i pogłowie krów mlecznych. Podstawowym czynnikiem zróżnicowania regionalnego tego procesu jest skala rozdrobnienia agrarnego i rozmiary gospodarstw rolnych. Weryfikację tej hipotezy przeprowadzono poprzez analizę zmian w chowie krów w sektorze gospodarstw osób fizycznych (gospodarstw indywidualnych) w całym kraju i w dwóch regionach zdominowanych przez gospodarstwa indywidualne. Pierwszy to region południowo-wschodni cechujący się bardzo niekorzystną, a drugi środkowo-wschodni cechujący się stosunkowo korzystną strukturą obszarową gospodarstw rolnych. Wyniki badań wyraźnie wskazują, że w warunkach nasilającej się konkurencji rynkowej następuje koncentracja chowu krów, który przesuwa się do coraz wyższych grup obszarowych. W rezultacie w regionie rozdrobnionego rolnictwa widoczny jest silny, przy tym narastający, regres w pogłowiu. W regionie z korzystną strukturą gospodarstw regres w chowie krów, który wystąpił na początku przemian systemowych, został natomiast stosunkowo szybko zahamowany i już w okresie przedakcesyjnym zarysował się rozwój ilościowy i jakościowy pogłowia, który widoczny jest także w okresie poakcesyjnym.

Opis:
A major source of energy on Earth is solar irradiation. This paper uses the Kolmogorov-Zurbenko filter to smooth and examine sunspot numbers and proves that solar irradiation levels near Earth are strictly proportional to sunspot numbers. This paper also examines the transport of that energy through the atmosphere to Earth’s surface. Long term air temperatures on the surface of Earth perfectly follow the cosine square law along latitudes. Time components of long term temperatures have oscillations which follow oscillations in sunspot numbers, but due to the regular delays in energy transmission they are delayed 4-7 years. Cloud formations and vapor accumulations also contribute to those delays, which have a well-organized time-space structure. The main purpose of this paper is the numerical identification of human influence over changes in solar activities, which may allow researchers to identify the effects of various sources of those influences. This evaluation can only be achieved by separating the scales in order to avoid any false influence from other scales. The clear separation of scales can only be achieved using the Kolmogorov-Zurbenko filter.

Opis:
The author’s aim is to identify changes in the rate, intensity and direction of hotel development, as well as their number, type and capacity of in Poland, by category and province in 1990-2015. The objective is to define the influence of both tourism attractiveness and economic development factors (GNP, total capital expenditure, the value of gross fixed capital formation – GFCF) on the changing number of hotel rooms. The identification was based on commonly available materials provided by the Local Data Base (LDB) of the Central Statistical Office (CSO), as well as from statistical year books concerning the tourism sector. The article presents methods for analysing indices, as well as correlation and graphic presentation (graphs, maps). From 1990 to 2015, there was a rapid increase in the number and capacity of hotels in Poland (4.5 times), especially in higher (5* and 4*) and medium standard (3*) hotels. That increase was significantly diversified regionally and strongly depended on the tourism attractiveness and socioeconomic development of provinces.

Opis:
The Curonian Lagoon is a shallow freshwater lagoon of significant environmental value in the south-eastern part of the Baltic Sea. The objective of the study was to evaluate changes of ice indices (duration, thickness and breakup dates) of this lagoon and to assess their possible tendencies in the 21st century. A methodology was developed combining the assessment of past changes (1960–2017) of ice indices and their projections in the near (2021–2040) and far (2081–2100) future periods using a hydrometeorological database, statistical methods and regression analysis as well as regional climate models and RCP scenarios. Climate change has a considerable impact on ice conditions in the Curonian Lagoon. During the historical period of 1960–2017, the Curonian Lagoon was covered with ice for 72 days a year, ice thickness reached 23 cm, whereas ice breakup was observed in the middle of March on average. According to the different scenarios, in the near and far future periods, ice duration will last 35–45 and 3–34 days, respectively. Ice thickness is projected to be 13–15 cm in the near future, whereas, at the end of the century, it is expected to decline to 0–13 cm. In the past, the lagoon ice cover remained until the middle of the third decade of February. At the end of the 21st century, RCP8.5 scenario projects the most drastic shifts: the permanent ice cover might be absent, whereas short-term ice cover is expected to melt already in the beginning of January.

Opis:
Climate model results for the Baltic Sea region from an ensemble of eight simulations using the Rossby Centre Atmosphere model version 3 (RCA3) driven with lateral boundary data from global climate models (GCMs) are compared with results from a downscaled ERA40 simulation and gridded observations from 1980 –2006. The results showed that data from RCA3 scenario simulations should not be used as forcing for Baltic Sea models in climate change impact studies because biases of the control climate significantly affect the simulated changes of future projections. For instance, biases of the sea ice cover in RCA3 in the present climate affect the sensitivity of the model’s response to changing climate due to the ice-albedo feedback. From the large ensemble of available RCA3 scenario simulations two GCMs with good performance in downscaling experiments during the control period 1980–2006 were selected. In this study, only the quality of atmospheric surface fields over the Baltic Sea was chosen as a selection criterion. For the greenhouse gas emission scenario A1B two transient simulations for 1961 –2100 driven by these two GCMs were performed using the regional, fully coupled atmosphere-ice-ocean model RCAO. It was shown that RCAO has the potential to improve the results in downscaling experiments driven by GCMs considerably, because sea surface temperatures and sea ice concentrations are calculated more realistically with RCAO than when RCA3 has been forced with surface boundary data from GCMs. For instance, the seasonal 2 m air temperature cycle is closer to observations in RCAO than in RCA3 downscaling simulations. However, the parameterizations of air-sea fluxes in RCAO need to be improved.

Opis:
Global climate change is anticipated to have consequences on water resources and the environment both at global and local/regional levels. Efforts towards proper management of future water resources and resolving potential water-related conflicts require the formulation of appropriate techniques to downscale the output of global climate models (GCM) to local conditions for hydrologic prediction. The paper presents an integrated framework for modeling the impact of climate change on river runoff that combines methodology for downscaling climate change scenarios for a basin scale with a hydrological model to estimate the impact of climate change on a river runoff. The modeling framework uses long-term observations of meteorological and hydrological variables together with a climate change scenario to provide a projection of future flows for the specified time horizon. The framework is based on a spatial weather generator and a distributed rainfall-runoff model. Such a configuration enables a reflection of the uncertainty of future conditions by running multiple realizations of future conditions, and also take into account the spatial variability of hydrological properties in the catchment by maintaining the physical details at a given grid size. The performance of the framework was presented for the Kaczawa basin that is one of the main left bank tributaries of the Odra River – the second biggest river in Poland. The results show simulated changes of the future river flow regime caused by climatic changes for two time horizons: 2040 and 2080.

The purpose of the paper was to synthetically characterise the changes of spatial differentiation of industry innovation in Poland in 2005–2015 in the context of research problems of innovativeness with the use of the cross product. The availability of data limited the scope of the research. For example, innovative activity was presented through the analysis of the share of innovative units in the total number of industrial enterprises and the size of expenditure on innovative activities incurred by industrial enterprises. The analysis of the share of innovative products in the value of total production and net revenues from sales of innovative products in net revenues from total sales was also made. The analyses mentioned were presented against the research and development situation in Poland as a whole and by voivodeship. Research confirmed that significant spatial diversity distinguishes the spatial structure of innovation in Polish industry by voivodeship. Moreover, it is significant that innovative expenditures show low efficiency.Spatial structure of industry innovativeness in Poland was highly stable in the analysed period. The changes in the spatial structure were insignificant and reached only 4% in synthetic terms. More substantial transformations of the structure, often of an abrupt character, concerned only the selected features of industry innovativeness.

Timely and accurate detection of land use/land cover (LULC) change is important for the macro and micro level sustainable development of any region. For this purpose, geospatial techniques are the best tool for change analysis as they supply timely, cheaper, precise and up to date information. This paper examines the spatial temporal change trend in LULC in the case of Central Haryana. Landsat 2, 3, 5, 7 and 8 images for the years 1975–2020 for pre and post monsoon periods were analyzed for the study. Radiometric correction was performed to derive better information. ArcGIS 10.2 and ENVI 5.3 are used for thematic layout and thematic change preparation. An unsupervised classification using ERDAS IMAGINE 2015 has also been done to classify study area in eight classes. The year 1975 is considered as the base year for change detection analysis. Results showed an increasing trend for the land use classes of built up, water body, and agricultural land without waterlogging in the pre and post monsoon periods between 1975 and 2020. Remaining land use classes of agriculture with waterlogging, open waterlogged area, vegetation and fallow land/sand dunes decreased during the same period. Increased human activities have changed the LULC in the region and have had a great impact on its sustainable regional development.

Opis:
Subject and purpose of work: Agricultural production activity brings about specific environmental effects. The aim of the study was to analyse changes in agricultural production in regions of Poland (NUTS-2) in the context of environmental impact using the gross nitrogen balance. Materials and methods: The analysis covered the medium-term perspective of 2001-2016. The primary source of information was statistical data of the Polish Central Statistical Office (Główny Urząd Statystyczny - GUS). Results: During the 2002-2004 period, the balance of gross nitrogen balance in Poland did not change and amounted to an average of 47.5 kg N∙ha-1 UAA (Utilized Agricultural Area). The progressive extensification of plant production in the following provinces: Slaskie, Malopolskie, Podkarpackie and Swietokrzyskie, is accompanied by a rapid reduction in the stocking density of livestock. Conclusions: The nitrogen balance, highly differentiated regionally, just as its individual elements, show the potential differentiation scale of the agricultural impact on the state of the environment. Very high balance surpluses occurring in the Kujawsko-Pomorskie, Lodzkie and Wielkopolskie provinces may indicate high environmental pressure from the agricultural production.
Przedmiot i cele pracy: Działalności produkcji rolniczej niesie ze sobą określone skutki środowiskowe. Celem opracowania była analiza zmian produkcji rolniczej w regionach Polski (NUTS-2) w kontekście oddziaływania na środowisko z wykorzystaniem bilansu azotu brutto. Materiały i metody: Analiza obejmowała perspektywę średniookresową lat 2001-2016. Podstawowe źródło informacji stanowiły dane statystyczne Głównego Urzędu Statystycznego (GUS). Wyniki: W latach 2002-2004 saldo bilansu azotu brutto w Polsce nie uległo zmianie i wynosiło średnio 47,5 kg N∙ha-1 UR. Postępującej ekstensyfikacji produkcji roślinnej w województwach: śląskim, małopolskim, podkarpackim, świętokrzyskim towarzyszy gwałtowne zmniejszenie obsady zwierząt gospodarskich. Wnioski: Silnie zróżnicowane regionalnie sald bilansu azotu jak i jego poszczególnych elementów pokazują potencjalną skalę zróżnicowania oddziaływania rolnictwa na stan środowiska. Bardzo duże nadwyżki bilansowe występujące w województwach kujawsko-pomorskim, łódzkim i wielkopolskim, wskazywać mogą na dużą presję środowiskową ze strony produkcji rolniczej.

Subject and purpose of work: The objectives of the elaboration are the following: 1) to analyze the regional changes (at the level of poviats) in the number of farms involved in milk production over the period 2002-2010; 2) to present the main factors affecting the ongoing changes in Polish farms oriented at milk production; 3) to determine the impact of the measure 121. “Modernization of agricultural holdings” under the RDP 2007-2013 and the applied system of direct subsidies for the development of farms oriented at milk production. Materials and methods: The work has been prepared on the basis of the analysis and synthesis of the source literature, statistical data collected and the author’s own reflections. Results: In Poland, in the years 2002-2010 there was a distinct regional differentiation in the pace of the ongoing changes in the dairy sector. The regions, where we observe the development of milk production, include almost the entire Podlaskie Province, the northern part of the Mazowieckie Province and the south-eastern part of the Warmińsko-Mazurskie Province. Conclusions: Within the RDP 2007-2013, significant funds were allocated to support the modernization of agricultural farms. Mainly under the measure 121 “Modernization of agricultural holdings” the investments were carried out in relation to the purchase of mobile equipment, they represented 89% of all investments. This was partly due to the actual demand and administrative procedures that stimulated these types of investments.
Przedmiot i cele pracy: Cele opracowania sprowadzają się do: 1) analizy zmian regionalnych (na poziomie powiatów) w liczbie gospodarstw zajmujących się produkcją mleka w latach 2002-2010; 2) przedstawienia głównych czynników oddziałujących na dokonujące się zmiany w polskich gospodarstwach ukierunkowanych na produkcję mleka; 3) określenia wpływu działania 121. „Modernizacja gospodarstw rolnych” w ramach PROW 2007-2013 oraz stosowanego sytemu dopłat bezpośrednich na rozwój gospodarstw ukierunkowanych na produkcję mleka. Materiały i metody: Praca została wykonana na podstawie analizy i syntezy literatury przedmiotu, zebranych danych statystycznych oraz własnych przemyśleń autora. Wyniki: W Polsce występowało w latach 2002-2010 wyraźne zróżnicowanie regionalne w tempie dokonujących się zmian w sektorze mleczarskim. Do regionu rozwijającego produkcję mleka można zaliczyć prawie całe województwo podlaskie, północną część województwa mazowieckiego oraz południowo-wschodnią część województwa warmińsko-mazurskiego. Wnioski: W ramach PROW 2007-2013 przeznaczono znaczne środki na dofinansowanie modernizacji gospodarstw rolniczych. Głównie w ramach działania 121. „Modernizacja gospodarstw rolnych” realizowano inwestycje związane z zakupem sprzętu ruchomego, które stanowiły 89% wszystkich inwestycji. Wynikało to po części z faktycznego zapotrzebowania oraz procedur administracyjnych, które stymulowały tego typu inwestycje.

Heavy precipitation events in Lithuania for the period 1961–2008 were analysed. The spatial distribution and dynamics of precipitation extremes were investigated. Positive tendencies and in some cases statistically significant trends were deter- mined for the whole of Lithuania. Atmospheric circulation processes were derived using Hess & Brezowski’s classification of macrocirculation forms. More than one third of heavy precipitation events (37%) were observed when the atmospheric circulation was zonal. The location of the central part of a cyclone (WZ weather condition subtype) over Lithuania is the most common synoptic situation (27%) during heavy precipitation events. Climatic projections according to outputs of the CCLM model are also presented in this research. The analysis shows that the recurrence of heavy precipitation events in the 21st century will increase significantly (by up to 22%) in Lithuania.

Opis:
Purpose: The purpose of the analysis is to demonstrate the potential impact of the shortcomings of public statistics collections in the field of application of demographic data to regional and local development planning. Design/methodology/approach: Taking into account the importance of human capital for the development of modern economies, acquiring information that reflects the demographic reality seems to constitute one of the crucial aspects determining the quality of planning the development of territorial units. The use of indicators relating to the outdated number or structure of the population in the process of diagnosing the baseline situation may lead to incorrect determination of the competitive position of territorial units and to defining development objectives that are an inadequate match to real challenges and needs of the respective territorial unit. This results in the requirement to correct the data on the number of people available in official statistics with data on unregistered emigration or the use of alternative data sets, such as the social insurance records. Findings: The use of this type of data within the framework of the conducted analysis rendered it possible to identify that the difference between the number of people, as determined on the basis of official registers, and the corrected population status, reaches 2.7-2.9 million people nationwide. Taking this fact into account causes effects in the form of an increase in the value of GDP per capita, both at the nationwide, and at regional scale. Originality/value: Therefore, it can quite clearly change the assessment of their economic potential, putting them in a more advantageous competitive position compared to other EU regions or member states. Consequently, it creates a different starting point for both defining regional or local development objectives and planning public intervention in line with the theory of change.

Opis:
In contrast to dramatic losses of the Atrypida and Pentamerida at the Frasnian–Famennian boundary, the Rhynchonellida demonstrated relatively high rate of survival, and recolonized vacated benthic ecospace after the F–F extinction events. The Late Devonian evolution of rhynchonellid faunas from the East European Platform shows three distinctive periods of their mass appearance. High abundance of rhynchonellids is characteristic for early–middle Frasnian (Palmatolepis transitans–Pa. punctata zones) and early Famennian (Pa. crepida Zone). Invasion of taxonomically diverse and rich rhynchonellid faunas usually corresponds to the major transgressive episodes, whereas decline coincides with regressive conditions of the basin. Rhynchonellid assemblages were replaced in the late Frasnian (Late Pa. hassi–Pa. linguiformis zones) by theodossiid− and cyrtospiriferid−dominated assemblages, which occupied habitats in newly expanding marine environments. The extinction of theodossiids at the end of the Frasnian and the next transgressive episode possibly stimulated an expansion of rhynchonellids. The early Frasnian species Ripidiorhynchus livonicus (Buch, 1834), and the early Famennian R. huotinus (Verneuil, 1845) and R. griasicus (Nalivkin, 1934) are revised. Early Famennian species Paromoeopygma koscharica (Nalivkin, 1934) from the central region is redescribed. Ripidiorhynchus chencinensis sp. nov. from the latest Givetian of Poland, as well as Globulirhynchia minima sp. nov. from the late Frasnian of the central region of the Russia, are described.

Opis:
Effects of the climate change appear in several fields of the economy and agriculture can be considered as one of the most affected among them. In a country, where almost 10% of the total GDP is produced by the agricultural sector and more than 30% of the total work force is employed in this field, these changes may have severe economic impacts. As in Romania almost 65% of the agricultural production is represented by vegetal production, we concentrate our investigations on this agricultural sector. Our aim is to present, basing on econometric modeling, how the climate changes will affect the Romanian crop production in the next 20 years, highlighting the territorial differences which appear between the Romanian NUTS2 development regions. This paper presents some of the first results of the FP6 research project “CLAVIER – Climate Change and Variability: Impact on Central and Eastern Europe”, contract no. 037013 (2006-2009).

Opis:
The aim of this study was to present basic trends in population processes in rural areas of the Świętokrzyskie Voivodeship. With the period of 2003-2008 the main subject focused on changes in population size, elements responsible for the character of population changes with components of natural and migratory movement. Changes in the labour market against changes in the number of people em-ployed and unemployment were also discussed. The analysis proved considerable spatial diversification of the processes in question.Positive population-related phenomena were recorded in municipalities located in a suburban zone, whereas negative phenomena occurred in the outskirts of the area and locations of economic restructuring.
