    Opis:
    The objective of this study is to map through multisource data, the change in land use structure and quantify its evolution around the semi-arid watershed of Wadi Sarno of Sidi Bel Abbès between 2000 and 2021. To this end, satellite images of 2000 and 2021 have been exploited by remote sensing and GIS, as well as field surveys for verification and validation of the results obtained. The methodology is based on supervised classification by maximum likelihood from the processing of satellite images. The analysis of the dynamics of land use shows that the areas of natural formations (dense forest and bare land) have decreased from 17,560 ha to 15,516 ha, that is to say, a regression of 8.04%, while the anthropised formations (Agriculture, open forest and rangeland, built-up areas, water bodies) have experienced an increase in their surface area, they have gone from 7901 ha to 9945 ha, that is to say, 10.4% of the total surface area of the basin. In the light of these results, it is possible to define priority areas for restoring degraded zones and enhancing natural formations. by giving priority to perennial crops to fix the soil in place and benefit from additional income for the region's farmers. By planting hardy species such as olives, figs, almonds, carob trees and so on. These species have proven their effectiveness and adaptation to local soil and climate conditions.

    Opis:
    The article presents the results of a study on archaeological structures and horizons developed in the palaeolake shore-zone of the Serteya II site that was occupied intermittently and to a greater or lesser intensity from the Mesolithic up to the Middle Ages. The Serteya II site is a multilayer complex used by hunter–fisher–gatherer communities in the 9th–8th mill. BC, and from the end of the 7th till the end of the 3rd mill. BC. The article is focused on the particularities of the formation of archaeological layers and the reconstruction of the ancient environment in different periods of time. The study of the sets of artefacts, their state of preservation, as well as the traits of archaeological features, may indicate the peculiarities of the formation of different sedimentological units. Based on the results of complex natural-scientific research it was possible to reconstruct the palaeo-ecology of changing water regimes as well as changes in environmental conditions.

    Opis:
    The purpose of the work is to evaluate the variability of bioclimatic conditions and their diversity in areas of a different degree of anthropogenic transformation. An important element of the work is to determine frequency of certain biothermal conditions in the analysed areas, strongly exposing the human body to heat and causing thermal stress of a various intensity. The most important meteorological parameter considered in this paper was the air temperature, because out of physical stimuli it is the one which is most intensely perceived, especially when its fluctuations occur at short-time intervals. The research was based on the meteorological data made available by the Voivodship Inspectorate of Environmental Protection (WIOŚ). The data come from automated measurement stations operating as part of air quality monitoring system, located in different districts of Warsaw and outside the city. Each of the stations is marked by individual features resulting from a different degree of anthropogenic transformation of the closest surroundings.
    Celem pracy jest ocena zmienności warunków bioklimatycznych i ich zróżnicowania na terenach o różnym stopniu przekształcenia antropogenicznego. Ważnym elementem pracy jest określenie częstości występowania określonych warunków biotermicznych na analizowanych obszarach, silnie obciążających gorącem organizm człowieka i wywołujących stres ciepła o różnym natężeniu. Elementem meteorologicznym zastosowanym w opracowaniu jest temperatura powietrza, bowiem jest najintensywniej od czuwalna spośród bodźców fizycznych, zwłaszcza gdy jej wahania występują w krótkich odstępach czasowych. Dane uwzględnione w opracowaniu pochodzą z automatycznych stacji pomiarowych, działających na ramach monitoringu jakości powietrza i zlokalizowanych w różnych dzielnicach Warszawy oraz poza granicami miasta. Każda ze stacji charakteryzuje się indywidualnymi cechami ze względu na różny stopień przekształcenia antropogenicznego najbliższego otoczenia stacji.

    Opis:
    Anthropogenic factors cause an increase in the impact on the natural system as a whole and its components. An increase in the intensity of this influence is predicted in the 21st century, and its forms are very diverse and unevenly distributed across the globe. This is most noticeable in industrialized countries, but at the same time this influence largely depends not only on the industrial potential and the level of technology, but also on the population density and urbanization of territories. Currently, much attention is being paid to the ecological problems of river catchments, which are significantly transformed as a result of technogenic influence on the natural environment. Surface runoff of water and sediments is usually formed in the river basin as slope runoff entering the river network. The river basin regulates the surface runoff formed as a result of atmospheric precipitation, which discretely falls on its surface, transferring a significant part of it into the underground runoff. The state of forest landscapes plays an important role in the formation of floods in the Dniester basin. The forest performs important ecological functions, including water protection and soil protection. Forests stabilize soils, preventing their erosion. The presence of a sufficient area of forests contributes to the regulation of surface runoff and the hydrological regime, the prevention of soil erosion and the stabilization of riverbeds. The use of water and mineral resources, construction on the banks of rivers and the laying of engineering communications through them are always different forms of artificial influence on the natural course of channel processes, which change it to varying degrees. Measures that change the channel-forming activity of the river, disrupt the flow of sediments, or radically change the hydraulic characteristics and structure of the flow have a particularly negative impact. The generalization of the dynamics of the channel process and ecological indicators within the territories of the Carpathian region will allow us to assess their impact on the state of the river network, the change in the quality of natural waters, and predict floods.
