This paper presents the results of geohazards mapping and evaluation their role in the modifying of the urban landscape in Poznań, Poland. Information on geohazards specific to an urban lowland area (river floods, flash floods, mass movement, wind erosion) because of increasing climate change was compiled into a geomorphological map. The most spatially widespread geohazards in Poznań include: (a) on moraine hills/uplands: mass movement, wind erosion, and flash floods (4.9% of the city area); (b) on outwash plains: mass movement and flash floods (8.6% of the city area); (c) on fluvial landforms: mass movement and river floods (9.8% of the city area); (d) within plains of various origin: flash floods (7.6% of the city area). Mass movement affecting short but numerous (and locally steep) slopes, and flash floods are the most widespread geohazards (16 and 14%, of Poznań’s area, respectively). Extensive urbanisation especially the expansion of impervious surfaces increases the high risk of flash floods.

Das Grab aus Kruszyn, 2009 in Kujawien entdeckt, rechnet zu einer kleinen Regionalgruppe der Schnurkeramik. Es zeichnet sich durch einen verhältnismäßig guten Erhaltungszustand und untypisch zahlreiche, aus Knochen und Geweih gefertigte Werkzeugbeigaben aus. Die aufgedeckten sterblichen Überreste wurden anthropologisch und isotopisch analysiert (La tombe de Kruszyn, découverte en 2009 dans la région de Cujavie, fait partie d’un petit groupe régional de la culture à céramique cordée. Elle est relativement bien conservée et se distingue par un riche assemblage d’outils, fabriqués en os et en cornes.

Noteworthy is a fairly good state of its preservation and a remarkably numerous assemblage of tools made of bone and antler. Unearthed human remains were anthropologically studied and examined isotopically (Grób z Kruszyna, odkryty w 2009 r. na Kujawach, należy do niewielkiej regionalnej grupy kultury ceramiki sznurowej. Wyróżnia się on stosunkowo dobrym stanem zachowania oraz nietypowo licznym zbiorem narzędzi wykonanych z kości i poroża. Szczątki ludzkie poddano analizom antropologicznym i izotopowym (

The archaeological microregion in Bruszczewo located along the middle course of the Samica River, was inhabited during the Bronze and Iron Ages by Únětice and Lusatian Urnfields culture people. Earlier literature emphasised that the valley floor was an extensive lake during the Bronze Age. Our research aimed to reconstruct the Bronze and Early Iron Age development of the lake and its transition into peatland. Using environmental archaeology methods, we marked the significant turning points in the lakes history. During the Early Bronze Age, a deep eutrophic lake was present on the valley floor, which supported the defensive nature of the nearby Únětice culture settlement. Around ca. 1880–1690 cal. BC, the lake underwent transgression, forcing people to create a fascine in the shoreline zone of the settlement. Terrestrialization of the lake began ca. 790–540 cal. BC with a gradual overgrowing that ended around the threshold of the eras. When compared to the results from other sites, it seems that these turning points were probably instigated by local triggers rather than global climatic events.

Grapevine is a highly climate-sensitive plant. In the last few decades, an increase in the number and area of vineyards has been observed in the country, with the Zielona Góra region pioneering this revival. A comprehensive analysis of climatic and agroclimatic indicators for grapevines was conducted to assess the possibilities and limitations in this region. Based on data obtained from the Institute of Meteorology and Water Management—National Research Institute (IMGW-PIB) for stations in Zielona Góra, nine key indicators were identified. The analysis of agroclimatic conditions for the Zielona Góra winegrowing region from 1951 to 2022 revealed significant changes in air temperature, length of the vegetative period, and number of frosts. The average annual air temperature increased, while the number of days with temperatures below 8 °C decreased. The extension of the vegetative period (starting earlier and ending later) favours grapevine cultivation. The increase in temperature during the vegetative period and the lengthening of the frost-free period have a beneficial effect on grape production in the Zielona Góra region.

This article presents the results of analyses of the chemical composition of organic matter and the occurrence of characteristic geochemical and biochemical markers in 17 samples collected from the Second World War mass graves excavated in the Szpęgawski Forest and Death Valley, Poland. The results show that attempts to cover up mass crimes by burning the bodies of the victims have left their own traces—that each attempt to cover up the crime is associated with the creation of further evidence of the crimes committed.
