According to the data of the Central Statistical Office, there has been an increase in forest cover in Poland from 27.8% to 29.6% over the last 25 years. This increase contributed to an increase in the possibility of wood obtaining and processing for energy purposes. The aim of the study was to analyse the efficiency of a chipping machine manufactured by the American Company Bandit Industries (Bandit 990XP chipper) based on the working day chronometer. The study was carried out in specific conditions related to the place of the chipper application because the machine was used to process the material obtained from standing trees in the framework of park maintenance. As it was shown during the analysed working day, the effective capacity W1 in the work cycle of the Bandit 990XP machine was 9.2 m<sup>3</sup>∙h<sup>–1</sup> chips. Specific working conditions made it impossible to organize the work smoothly. Ongoing obtaining of the material for chipping from standing trees resulted in low productivity during the exploitation time of the shift W08 on the level of 1.3 m<sup>3</sup>∙h<sup>–1</sup> chips.

Green space is essential for the implementation of the idea of sustainable urban development. This paper contains original research on the implementation of local government tasks in the development of public green space. The aim of this research was to analyse the actions taken by the municipal authorities regarding the development of public green space, including the acquisition of real properties, the regulation of their legal status, as well as the adoption of planning and programme documents. The Polish Central Statistical Office data on the public green space of the largest cities in Poland were analysed in order to determine the dynamics of changes. Then, the focus was placed on Krakow, where the authors analysed in detail the distribution and type of urban green space as well as the actions taken by the Municipality to both extend it and to protect it against building development. The criterion of green space accessibility to city residents was indicated as a necessary aspect to be considered in the overall assessment of the existing greenery. The conclusions include the assessment of the actions of the Krakow authorities and the observed trends in the development of public green space.

This paper presents a case-study to demonstrate the calculation methods of growth contributions using structural decompositions of input-output tables and their Hungarian applications. Although the required data are available with a considerable time-lag, results show that taking backward linkages through demand for inputs and value chain multipliers into account can significantly alter the picture on the growth effects of industries and final demand categories by the conventional approach based on quarterly GDP calculations. This can be instructive for analysts and policy- and decision-makers not only in Hungary, but also in other countries. The study was performed by using public macroeconomic and sectoral data obtained from the Hungarian Central Statistical Office.

Abstract The aim of this paper was to evaluate the intensity of rural area marginalisation. As a study region, Western periphery of Poland has been chosen. The spatial scope of the research covers three border voivodeships: Dolnośląskie, Lubuskie and Zachodniopomorskie, however, the study was conducted at the local level, including 310 rural and rural-urban gminas (administrative region of the 3rd order in Poland). The statistical data were derived from the Central Statistical Office from the period of last two decades. Results revealed the differences in the level of rural area marginalization and were analysed in terms of agricultural and socio-economic aspects.

Abstract The aim of the paper is to present the potential for afforestation of agricultural lands under the ‘National Programme for Expanding of Forest Cover’ (KPZL) in Poland until 2020. The analysis is based on the ongoing social and economic changes in rural areas in the past decade as well as factors limiting implementation of the Programme. The data used have been derived from annual reports of the Agricultural Property Agency (ANR), the Central Statistical Office and also other official documents and legal acts related to the issue. Assuming that the area of agricultural lands transferred by the ANR to the State Forests Holding – an institution responsible for implementing the KPZL on state-owned lands – remains approximately 350 ha per year, the overall extent of afforestation on state-owned lands will not exceed 4,500–4,600 ha until 2020. In case of private lands, a further decline in annual afforestation area will be observed. The lack of a stable financing system is a major reason for the decrease in the area of agricultural lands transferred for afforestation. The projections show that the average annual afforestation area on private lands will not exceed 2,500 ha until 2020. Altogether, it can be expected that during the period 2015–2020, approximately 20,000 ha of agricultural lands will be afforested. The study shows that the current rate of afforestation is insufficient for reaching the target defined in the KPZL (afforestation of 680,000 ha of lands during the period 2001–2020). Low supply of private lands for afforestation and insufficient financial support for farmers are the most important factors limiting the implementation of the KPZL. The situation could be improved by free transfer of public lands for afforestation from the ANR to the State Forests Holding and by implementing financial instruments for afforestation of private lands from the Forest Fund resources.

Abstract The authors in this article present performance of public administration which concerns a basic process developing in the context of dynamics of security culture phenomenon that involves the use of local potential (including infrastructure, natural environment, finance, human capital). The process of development of a region is multifaceted. It involves any changes that are implemented at different paces and with varying intensity in economic, social, technical and environmental areas. Local security is a resulting category that allows to assess functioning of local economy. The aim of the article is to provide determinants that shape security at the local level in the context of the selected elements of the region’s balance (infrastructure and environment aspects) by the case of Swietokrzyskie Voivodeship municipalities for 2010 and 2015. In the calculations the data of the Central Statistical Office (Local Data Bank) were used. The determined synthetic measure allows to make hierarchy according to the adopted variables. It supplies information on the examined category of objects. It provides a comparative picture between the objects that were analysed, allows to indicate weaker and better areas of functioning of a unit. As it is shown in the article it gives a basis for the assessment of the effectiveness of the instruments of local authorities policy that were used in the past. The carried out statistic studies confirm existence of disparities in financial condition (financial security) of municipalities.

The objective of the case study was to give an overview of differences between Hungarian regions from the aspect of socioeconomic factors. The paper deals with the distinct situations of NUTS 2 regions in order to get a general view of the country from that angle. Although, that approach is not the most detailed one, it makes possible to easily distinguish the competitive parts of the country. Secondary data were provided by the Hungarian Central Statistical Office (KSH) and National Territorial Development and Spatial Planning Information System (TeIR) were used to present the distribution of population by various expositions. Unemployment rate, distribution of educational attainment, population growth, rate of ageing, vitality index, dependency ratio and GDP per capita were calculated and assembled to present the differences. The results are showing clearly, that Central Hungary (HU10), Central Transdanubia (HU21), Western Transdanubia (HU22) are currently competitive. The population of Southern Transdanubia (HU23) and Southern Great Plain (HU33) are aging, but stable from the view of economy related indexes. Northern Hungary (HU31) and Northern Great Plain (HU32) are considered laggards from that aspect, but have a considerable potential because of the age structure of the population. The paper also introduces some national and EU programmes which are meant to mitigate the effects of unfavourable situations.

Urban retail systems in Poland have been changing constantly during the last 30 years. When it seemed that the consumption lifestyle of Poles became stable, and likewise the relations within the urban retail system, it was placed under the strain of the shock of the pandemic. The aim of the study is to discuss challenges that the urban retail systems face as a consequence of the COVID-19 pandemic, how the relationships within those systems have changed and how the resilience of entities that create urban retail systems has changed. The article focuses on the case study of Poland, the largest and the fastest growing country in Central and Eastern Europe. To achieve the research goal, a broad and detailed critical literature review was used: literature, scientific articles, reports and daily press with a business profile were analyzed. Complementary to a qualitative approach was an analysis of quantitative data from the Central Statistical Office of Poland and Eurostat regarding the period from 2007 to 2021. The COVID-19 pandemic constitutes a unique occasion in which to conduct a stress-test of the concept of retail resilience in the lively organism of a city; it also delivers a useful framework for analyzing processes occurring in the Polish retail trade. The undertaken research contributes to these concepts by indicating how the shock of COVID-19 could affect components of the urban retail system in ambivalent ways as they express different levels of resilience. Some elements of the system had no problems with adjustments to the shock of the pandemic, whereas others with more rigid structures had problems with adaptation.

AbstractConstituting the key element of a democratic system, political parties are among entities obliged by the Polish legislator to comply with the principle of disclosure by providing public information. The main objective of this paper is to determine the level of Polish political parties’ disclosure, understood here as their willingness to disclose information on their own structures. It seems that the practice of disclosing such basic organizational data may constitute a specific measure of Polish political parties’ respect for the idea of disclosure. The subject matter of the conducted research was particular parties’ sites in the Public Information Bulletin as well as their official websites. An attempt was made to acquire data concerning party structures by way of direct contact with particular parties’ organizational units – questionnaires were sent to both central and regional/district organizational units. In order to acquire a wider perspective, the research also included data provided by the Central Statistical Office concerning political parties’ organizational structures and election manifestos. The conducted analysis was summarized in the form of a ranking of the examined political parties based on a proposed political party disclosure index. This attempt to measure disclosure on the basis of data on internal structures provided by parties themselves is of a preliminary character which, nevertheless, makes it possible to capture the general properties of the phenomenon under analysis. Among the examined parties, it is PSL, SLD, and PO that, to an acceptable degree, follow the principle of disclosure in the analysed scope (indexes at the level of 60%-80% of the maximum value). Four other parties, i.e. N, Wolność, Razem, and Kukiz’15, are on the edge of the zone making it possible to regard their disclosure as sufficient (indexes at the level of around 50% of the maximum value). In the case of PiS, whose index does not reach 20% of the maximum value, it should be concluded that this party implements the principle of disclosure at a minimum level. The ranking did not show relationships between parties’ willingness towards providing information and their sizes or positions on the political scene (parliamentary parties vs. extra-parliamentary parties).
