The municipal waste composition in three localities in southern Kosovo was analyzed in 2004 and 2017. The results show that most of the municipal waste is composed by biodegradable components and at a lesser degree by cardboard, glass, plastic, metals etc. The presence and increase of hazardous waste in municipal containers was observed in all investigated localities. This study showed that there was no significant change in the municipal waste composition in 2017 compared to 2004. This investigation through a case study in the Prizren Municipality is a contribution to the municipal waste management in Kosovo. It highlights the importance of including the registration of individual and organized cardboard, metal and plastic operators into the municipal waste management system, in order to know the exact amount of waste produced per capita. It also emphasizes the importance of organizing separate containers for hazardous waste due to the possible significant environmental and health problems.

In this study, the results of fish composition, distribution and abundance are presented according to the effects of water physicochemical parameters from the Livoq Lake in the eastern part of Kosovo. The fish specimens were sampled in six sampling stations in 2018 by using a variety of methods, including electro-fishing devices, fishing rod and cast nets. The measured physicochemical parameters included: water temperature, dissolved oxygen, saturation of dissolved oxygen, pH, conductivity, total dissolved solids. In total, 320 fish specimens were collected, belonging to 10 species of the following 5 families: Cyprinidae, Silurideae, Esocideae, Percideae and Centrarhideae. The most species rich family is Cyprinidae with 6 species in total: Cyprinus caprio Linnaeus, 1758, Rutilus rutilus Linnaeus, 1758, Carassius carassius Linnaeus, 1758, Squalius cephalus Linnaeus, 1758, Leucaspius delineatus Linnaeeus, 1758 and Alburnus alburnus Linnaeus, 1758. Four other families are represented by one species each: Silurideae with Siluris glanis Linnaeus, 1758, Esocidea with Esox lucius Linnaeus, 1758, Percideae with Perca fluviatilis Linnaeus, 1758 and Centrarhideae with Lepomis gibosus Linnaeus, 1758. The knowledge on fish fauna in Kosovo is still very fragmentary, and this investigation contributes to determining the qualitative composition and abundance features based on the water physicochemical parameters in this part of the Balkan Peninsula.

The freshwater ecosystems in Kosovo have undergone significant degradation in recent years due to various anthropogenic pressures, including sewage effluents, industrial discharge, water intakes, and riverbed degradation. Consequently, the populations of freshwater biota, including bioindicators, have been heavily impacted by these activities. This study provides a thorough evaluation of water quality in the main course and tributaries of the Ibër Basin, Kosovo, utilizing macroinvertebrates and benthic diatoms as bioindicators. The well-being of aquatic ecosystems is intricately tied to water quality, and these organisms serve as valuable indicators because of their sensitivity to environmental changes. Sampling of macroinvertebrates and diatoms was conducted at 20 stations in the basin. Diversity, abundance, and ecological indices obtained from macroinvertebrates and benthic diatoms were employed to assess the water quality status at various sampling sites. The findings indicate variations in macroinvertebrate and benthic diatom assemblages among different sites, reflecting anthropogenic impacts on water quality in most of the studies sites. The macrozoobenthos structure during this investigation consists of one class (Gastropoda), two subclasses (Hirudinea and Oligochaeta), eight orders (Diptera, Isopoda, Coleoptera, Amphipoda, Decapoda, Trichoptera, Ephemeroptera, and Plecoptera), and 26 families. The composition of diatoms includes 152 species, with the most diverse genera being Nitzschia Hassall 1845 (29 species), Navicula Bory, 1822 (18 species), and Gomphonema Ehrenberg, 1832 (9 species). The integration of biological and environmental data provides a holistic understanding of the ecological health of freshwater ecosystems of the Ibër Basin indicating severe deterioration at several of the study sites. The outcomes of this study can help develop informed water resource management strategies, facilitating targeted conservation and remediation efforts to improve and preserve the overall water quality in the basin. This research contributes to the broader field of freshwater ecology and underscores the significance of using bioindicators for effective water quality monitoring and management.

The conducted study aimed to investigate the quantity and composition of municipal waste deposited in landfills in the Peja District of Kosovo over the period of 2005–2021. The study covered four municipalities within the district: Peja, Klina, Istog, and Deçan. A total of 705,246.7 tons of waste were deposited during the analyzed period, with the municipality of Peja depositing the largest amount (428,347.9 tons) and Deçan the smallest (67,143.6 tons). Regarding the composition of waste, the majority of municipal waste consists of biodegradable components (about 38%), followed by plastic (20 %), paper and cardboard (17%), glass (7%), textile (5%), diapers (3%), tetrapak (1.5%), metals (1%), construction materials (1%) and small waste (6.5%). This investigation contributes to municipal waste management to know the exact amount of waste produced and its composition.

During the spring of 2011, forty-five macrozoobenthos samples were taken from streams and rivers all over the Dragash Municipality in order to assess the impact of inhabited areas in these freshwater ecosystems, considering the fact that there is no sewage treatment and waste management is dysfunctional in many parts of this Municipality. On the basis of the habitat structure evaluation, basic physical and chemical analysis and Family Biotic Index according to Hilsenhoff and EPT Index (Ephemeroptera Plecoptera Trichoptera), this study shows that the freshwater ecosystems in the Dragash Municipality are heavily polluted and impacted by human activities in their midstream and downstream segments. The main sources that deteriorate their natural ecological conditions in these segments are: load of all kinds of waste directly into the rivers and streams, industrial discharge into the freshwater ecosystems and the direct sewage discharge into the rivers and streams all over the municipality. This study also shows that the freshwater ecosystems of the area in their upper reaches are home to very interesting and rare composition of aquatic fauna. Several species and many potential ones which live only in this area and nowhere in Kosovo or abroad, or their distribution elsewhere is very limited, have been found.
