Geographia Polonica has been published since 1964; in the years 1964–1998 as a serial publication. Since 1999 – as a journal with two issues per year (Spring and Autumn), and since 2012 there are four issues per year (March, July, October, December). Contributions to the journal on both human and physical geography topics as well as related fields (e.g. urban and regional planning, ecology) should be submitted to the Editor. Papers dealing with Central and Eastern Europe are particularly welcomed.

Agriculture has been the major driver of deforestation in Europe in the last 1000 years. In the past, forests were also exploited for charcoal production; however, the spatial scale/extent of this activity and its impact are unknown. LIDAR data can be used as a noninvasive tool to investigate the small-scale diversity of the land relief, including forested areas. These data can reveal the extent anthropogenic modifications of topography present-day as well as in the past. One of the activities that can be analyzed based on LIDAR data is spatial distribution of charcoal production. A preliminary LIDAR data analysis indicated the intensity of this practice and its potential impact on the natural environment. This prompted us to analyze the environmental impact of charcoal hearths in northern Poland. As it turned out, this topic exceeded the scope of earth sciences and became a transdisciplinary one. In this work, we will use the research methods typical of biogeography, dendroecology, paleoecology, soil science, biology, botany, history, onomastics, as well as art history, in order to thoroughly understand not only the natural consequences but also the social and economic consequences of charcoal production. This paper presents the assumptions of our project, the research methodology, and the preliminary results. We have identified using LIDAR data more than 73 thousand relief forms which can be remnants of charcoal hearths. Our preliminary results confirmed large scale impact of past human activity related to charcoal production and suitability of the methods used for detecting and reconstructing charcoal hearths as well as determining the distribution and magnitude of past forest use for charcoal production in NW Poland.

Towards a quantitative reconstruction of lake trophic state in temperate lakes using subfossil cladocera and diatoms: Composition of a training set from NE Poland

Izabela Zawiska, Michał Woszczyk, Monika Rzodkiewicz

Geographia Polonica (2022) vol. 95, iss. 3, pp. 227-253

Further information


We present a training set, the database involving physical-chemical water parameters together with the subfossil Cladocera and diatoms community composition in the surface sediments of 64 postglacial lakes in NE Poland sampled along a wide trophic gradient (from oligo- to highly eutrophic). The most important water parameters measured in water were chlorophyll-a, electrical conductivity (EC) and oxygen concentration. In addition, total phosphorus (TP) and Secchi depth (SD) were determined for the surface water layer. The data collected will be used to calculate a transfer-function for quantitative reconstruction of trophic state in fresh water temperate lakes.

Keywords: Lake training-set, water properties, summer vertical profiles, subfossil Cladocera, subfossil diatoms

How Covid-19 pandemic influenced air quality in Polish cities – lessons from three lockdowns

Katarzyna Lindner-Cendrowska, Kamil Leziak, Peter Bröde

Geographia Polonica (2022) vol. 95, iss. 3, pp. 255-274

Further information


The aim of this study was to determine how COVID-19 pandemic influenced air quality in the chosen Polish cities. Data on nitrogen oxides, carbon monoxides, fine and coarse particulate matter concentrations from air quality monitoring stations was used to compare pollutants levels during the pandemic and in the 5-year pre-pandemicperiod. The impact of the pandemic on the air quality has been analysed using linear mixed effect models, adjusting for long-term, seasonal and weekly trends and meteorological conditions. Results showed that during the pandemic, until the second lockdown only nitrogen oxides levels were significantly reduced (up to 20%), while when again loosening restrictions the rebound effect led to 20-30% increase of all analysed pollutants.

Relationships between sunshine duration and air temperature in Poland

Dorota Matuszko, Krzysztof Bartoszek, Jakub Soroka

Geographia Polonica (2022) vol. 95, iss. 3, pp. 275-290

Further information


The aim of the paper is to characterize the trends of sunshine duration (SDU) and air temperature in Poland, which may help understand the mechanism of contemporary climate change. The daily totals of SDU and daily data on air temperature from the years 1971-2020, from 25 synoptic stations in Poland are the basic source data. The series of records of the two variables showed that the points of change in the level of stabilization of the value of SDU and air temperature are close to each other, and confirm known in the literature “globaldimming” and “global brightening” periods. The linear regression model confirmed that sunshine duration explains well the variability of, and increase in day-time air temperature in Poland in the warm part of the year.
