A new locality for <italic>Crataegus ucrainica</italic> in the ravine-valley system of the River Svydnya valley (Desna basin) near the town of Krolevecz (Sumy region) has been reported. This article presents the results of a study of <italic>C. ucrainica</italic> within the species’ distribution. Based on a survey of the identified population, its ecological and coenotic features, and the ontogenetic state of the population are presented. The species is confined to areas with steep slopes, which are inaccessible for grazing, where clay deposits are exposed. The complexity of these ecotopes provides a good preservation of individuals in open meadows, forest edges, as well as in thickets of <italic>Robinia pseudoacacia</italic> and <italic>Populus alba</italic>. The coenotic affiliation of some individuals and thickets of this species to meadow-steppe, natural forest and spontaneous tree-shrub vegetation is noted. The state of the studied population in the Desna river basin is stable and sufficient for its preservation, its existence is due to the optimal hydrological regime of the slopes, which is associated with the presence of accumulated water at the bottom of valley s and a low groundwater level. The map shows the peculiarities of the distribution of the identified populations of <italic>C. ucrainica</italic> in Ukraine. A comparison of biotopes, ecotopes, soils, and vegetation types, in which populations of <italic>C. ucrainica</italic> in the area of their distribution are presented. Analysis of the seed products of this species according to analysis from different habitats allows us to assert the existence of favourable conditions for its distribution in the presence of optimal habitats.

The determinants of higher education policy have their sources in various spheres, such as economic, social, educational, national policy, administrative, and demographic. Problems for the development of higher education also stem from these spheres. One of them is the challenging demographic situation that is a significant element of developing higher education in southern Poland (particuarly in the Silesia region). Given this context, this article aims to indicate the policies of the universities in the region which respond to the existing demographic threats. This relationship is to confront student opinions regarding their vision for their education and future career within the current demographic situation. Using research-based on an analysis of university and regional local government strategic documents and surveys carried out among students, we conclude that higher education development policy is responding to the demographic transformation. Meanwhile, students’ attitudes to the challenges of the demographic situation is quite “flexible” and relatively ambivalent. This article presents the contrast between the increasingly tricky demographic situation in Silesia, Poland, and the limited response in the two main groups of stakeholders – academic authorities and students – that require shaping higher education ipolicy towards future demographic challenges.

An assessment of the socio-economic implications of landslide occurrence in the Kigezi highlands of South Western Uganda was conducted. Landslide occurrence is on the increase and threatens community livelihoods in these highlands. Detailed field investigations were undertaken with the help of local communities between June 2018 and May 2020 to identify and map recent and visible landslide scars in Rukiga uplands of Kigezi highlands. In the course of field inventories, 85 visible landslide scars were identified and mapped using handheld GPS receivers to produce a landslide distribution map for the study area. A socio-economic analysis was conducted to establish the effects of landslide damage on people’s livelihoods as well as their existing coping and adaptation mechanisms. The assessment was administered through field observations and surveying, focus group discussions, key informants and household interviews as well as the use of Local Government Environmental Reports. The study established an increase in the spatial-temporal distribution of landslides over the Kigezi highlands in the past 40 years. The landslides have resulted in a reduction in the quality of land, loss of lives, destruction of transport infrastructures, settlements, farmlands, crops and other socio-economic infrastructures. Therefore, it is important to look for reliable and sustainable measures to prevent landslide hazards. Total landscape reforestation with deep-rooted trees can possibly reduce the landslide risk. It is also important to undertake policy implementation for preparedness and mitigation plans against landslides in this region and in the country at large. Proper soil and water conservation measures could help in enhancing soil strength against landslide hazards.

Municipal waste landfill is a potential, or actual, source of groundwater pollution. Even landfill with a ground containment system can generate leachate that will migrate to aquifers. In this context, it is important to monitor water and leachate and to rationally analyze the existing situation. The purpose of this article was to assess groundwater contamination in the region of the municipal landfill site in Poczesna (Southern Poland) using the Landfill Water Pollution Index (LWPI). Certain physicochemical parameters such as pH, electrical conductivity (EC), total organic carbon (TOC), polycyclic aromatic hydrocarbon (PAH), Cd, Pb, Zn, Cu, Cr, and Hg, were analyzed from samples from six piezometers in the years 2015-2019. The LWPI index values in the groundwater samples ranged from 0.97 to 3.11 (P&lt;0.05). Indicator values that are within the range 2-5 reflect poor water quality with a high visible landfill impact, and those >5 suggest strongly polluted water with a very high landfill impact. The results of this study indicated that the quality of the groundwater in the area around the landfill was better in the case of the Jurassic aquifer compared to the Quaternary aquifer. The results provided by this index are very useful in the context of a quick assessment of groundwater quality. For the purposes of further risk analyses, it is important to consider other variables (chemical components) which can influence groundwater quality in the region of municipal landfill sites.

The current conservation status of the rare vascular plant species and rare forest communities of the Volyn Upland (Ukraine) was characterized and analyzed. We found 14 rare plant species belonging to the Red Data Book of Ukraine in this territory (<italic>Lycopodium annotium</italic> L., <italic>Allium ursinum</italic> L., <italic>Cephalanthera longifolia</italic> (L.)

Rich., <italic>P. chlorantha</italic> (Cust.) Reichenb., <italic>Galanthus nivalis</italic> L., <italic>Carex umbrosa</italic> Host) and 28 locally rare species preserved within the Volyn, Rivne and Lviv regions. The major threats for these species were indicated. Four rare associations, according to the Green Data Book of Ukraine, were studied in the Volyn Upland (<italic>Carpineto (betuli)–Quercetum (roboris) hederosum (helicis)</italic>, <italic>Carpineto (betuli)–Fraxineto (excelsioris)–Quercetum (roboris) alliosum (ursini)</italic>, <italic>Tilieto (cordatae)–Carpineto (betuli)–Quercetum (roboris) alliosum (ursini)</italic> and <italic>Pinetum (sylvestris) caricosum (humilis)</italic>) and their structure, main features and status were characterized in detail. The importance of further research, and the development of recommendations for the conservation and continued preservation of these forest ecosystems of the Volyn Upland was highlighted.
