Opis:: The World Meteorological Organisation predicts an increase in average annual temperature. As a result of climate change in Slovakia, one can expect changes in the distribution of precipitation and moisture availability, changes in the temperature availability of crop production, changes in wintering conditions, and many others. The aim of this work was the analysis of agroclimatic indicators for the period 1961–1990 and 1991–2020. The results showed an increase in the sums of temperatures in the growing season. Also, the increase in temperature resulted in a change in the zones of the agroclimatic indicator of moisture and the agroclimatic indicator of wintering. The zones have been shifting to higher altitudes throughout Slovakia.

Opis:: The paper deals with the problem of road noise pollution in the context of spatial development. The analysis was motivated by the changes in the permissible noise levels that occurred on 1 October 2012 and the high urban pressure on areas located along the main traffic routes. On selected examples of sites located in the districts of Bemowo and Białołęka in Warsaw, the location of land functions is shown on the background of the course of isophones of acceptable noise levels. The analysis was based on data from acoustic maps for Warsaw developed in 2012 and 2017, planning studies, database of topographic objects and current state of development. Based on 20 features and 9 surface and quantitative indicators, determined using ArcGis software, the degree of road noise pollution in planning terms was shown. The analysis has been demonstrated that the changes in legislation have resulted in the acoustic “freeing up” significant areas along the main road, express and accelerated main roads and a reduction in the number of buildings that were considered to be at risk of noise pollution by the law before 2012. The acoustic release indicators for the general area were in the range of 0.71–0.74 for LN and 0.56–0.74 for LDWN. In relation to acoustically sensitive areas the results were in the range of 0.81–0.84 for LN and 0.64–1.00 for LDWN.

Opis:: The objective of the work was to describe the thermal and snow conditions in the winter period in the Siedlce area. The average daily air temperatures were used in addition to numbers of days with a snow cover of at least 1 cm for the years 2000–2016 obtained from the Meteorological Station in Siedlce. Dates of the beginning and end of the winter season were determined. The average temperature of the winter season was determined in addition to the degree of winter severity, according to Oskin. The average, minimum and maximum values of parameters were calculated. The probability of an occurrence of individual types of winter severity was determined. Next, principal component analysis and cluster analysis were applied, the latter to the group years in terms of the days with a given type of weather in winter. It was found that – on average – the thermal winter began on 5 December and ended on 6th March. The winter was found to have lasted for 66 days. From year to year, there was observed an increase in the average number of days with mild weather. The greatest decline was found for the days with the weather typical of slightly severe and moderately severe winter. The last study years had the highest average number of days with weather typical of mild, slightly severe and moderately severe winter, and the lowest number of the days with weather typical of severe, very severe, unusually severe and extremely severe winter.

Opis:: Land use and the landscape of the suburban area are strongly affected by the impact of a large city, which is an important factor determining their development. The paper presents the results of analyses of the functional and spatial transformations depending on the distance from city limits and main access roads. The analyses were based on CORINE data for the years: 1990, 2000 and 2006. The spatial transformations in the specified distance buffers were described with use of the indicator of the share of specific land use areas in the total surface area and the indicator of the average landscape patch surface area. The conducted analyses confirm that the spatial patterns characteristic for suburbanisation exist in the vicinity of large cities and along access roads. The phenomena noticed in the suburban zone of Wrocław include, among others, an increased share of surface area used for residential purposes, a decreased area of arable lands, and an increased concentration of commercial and industrial areas in the direct proximity of the city and access roads.

Opis:: Along with sea-level rise, one of the most detrimental effects of climate change, is salinity leakage, which significantly affects agricultural activities throughout most of the world. This occurrence is becoming increasingly dangerous. The purpose of this study was to use Geographical Information Systems (GIS) to assess the current situation of agricultural lands in the province of Al-Diwaniyah, by employing GIS to document the salt-affected sites and arrive at the most important criteria affecting those lands as well as build an application model for suitability to clarify the affected sites and come up with paper and digital maps. To accomplish this, the study relied on the available data by extrapolating and analyzing remote sensing images using salt equations to analyze the Landsat 8 satellite images, after which these data were subjected to spatial statistical treatment in ArcGIS software. Moreover, 20 samples were taken from ground sampling points and subjected to laboratory analysis to compare and document the results. The research resulted in the creation of an up-to-date database for the locations of salt ratio growth or decrease in the province of Al-Diwaniyah, which can be relied on, starting from and expanding in the future. Land maps, both paper and digital, have been created and can be used and inferred. The findings demonstrated the model’s ability to steadily discriminate among all salinity groups while maintaining consistency with the ground truth data. Each of the four major salinity categories was highlighted. The best-performing indicators were used to build the MLR model, which was then used to anticipate soil salinity. The salt levels may be determined by the MLR combining NDVI and SI-5 with a high correlation value (R2 = 75.29%). Finally, it is shown that by combining spectral indicators with field measurements, it is possible to chart and forecast soil salinity on a large scale.

Opis:: The Tachypleus tridentatus (Chelicerata: Xiphosura) is an arthropod that usually displays high site fidelity by restricting its distribution to natal vicinities. Briefly, shore perturbation from boating (Kudat), electric, cyanide and bombing (Kunak) and tourism (Semporna) in Sabah can impair the T. tridentatus growth and produce sexually mature adults with unusual size. The 8-point morphometry of Tachypleus tridentatus from Kudat (Sulu Sea), Kunak and Semporna (Celebes Sea), produces the final output constituting accurate size classification for the species. Meanwhile, T. tridentatus are sexually dimorphic (p = 0.968–0.989), where male T. tridentatus (from Kudat) has prosoma width (27.75 ± 2.68 cm) and weight (1050 ± 610 g) in smaller ranges when compared to the female (33.27 ± 4.68 cm; 3020 ± 1480 g) using the same comparison. In addition, the T. tridentatus populations from Kunak (prosoma width: male = 28.91 ± 1.48 cm, female = 29.44 ± 5.47 cm; weight: male = 800 ± 275 g; female = 2550 ± 155 g) and Semporna (prosoma width: male = 21.73 ± 1.34 cm, female = 24.42 ± 1.36 cm; weight: male = 485 ± 306 g, female = 1320 ± 640 g) differed site-wise. The descriptive statistics (average and standard deviation) relate 7.1–23.0% of T. tridentatus with negative size class. However, the applied statistics using stepwise analysis and regression curve (r2 = 0.566–0.833), relates 30.4% of T. tridentatus with negative size class. Considering weight to produce 100% T. tridentatus with positive size class, it is biased because some crabs are gravid with eggs and if attained unpaired (male and female), they may have recently fed. Therefore, the prosoma (male), interorbit (female) and telson lengths are identified as most appropriate for the size classification of T. tridentatus. Thus, the findings provide a novel baseline for conservation studies that monitor symmetrical and unusual growth in the T. Tridentatus wild stocks.

Opis:: The seaside area is one of the most forested in the country. At the same time, the forests in the coastal zone are exposed to a strong anthropogenic pressure due to a high concentration of tourism development and tourism. The aim of the study was to analyze the changes in the forest area availability of the coastal tourist municipalities of the Baltic Sea Coast in connection with the changes in the area of tourism development and tourism in this area. The analysis was conducted in dynamic terms, taking into account the years 2000-2016. In this study, all the communes that directly border the Baltic Sea were taken into account as seaside communes. The statistical data of the Local Data Bank of the Central Statistical Office were used as the source material for the implementation of the research problem addressing: the changes in the area of total forests in all coastal communes of the Baltic Sea Coast in 2000-2016, the changes in the area and population of communes, and selected data on the tourist function of the coastal communes including the data on the number of facilities and beds as well as the number of tourists visiting the coastal communes of the Baltic Sea Coast between 2000-2016. In the coastal communes, in the years 2000-2016, the forest cover index increased from 23.3 to 24.1%. Since 2000, the forest area per 1 inhabitant increased from 1741 m² to 2149 m². The increase in the forest area and average forest area per capita occurred mainly in the rural communes, large communes with the highest forest cover indicators, in the urban communes while in the communes with a strongly developed tourism function, there was an opposite tendency. The increase in the tourism load on the forest areas and decrease in the availability of forests for tourists in the municipalities and communes with the largest tourist investment (Kołobrzeg, Międzyzdroje, Władysławowo) is observed. The anthropogenic pressure and the availability of forest decreases in communes with lower population and the marginal role of tourism in their socio-economic development (Choczewo, Trzebiatów, Smołdzino, Kamień Pomorski).

Opis:: Open pit coal mining is a global problem, because mines occupy large areas that completely change the relief, dramatically affect ecosystems, as a result of which they lose most of their functions, and a significant part of the fertile soil degrades and becomes unsuitable for agricultural activities. In the presented work, the initial stage of soil formation was studied, the parameters of the granulometric composition of uneven-aged rocks of Donbas mine dumps, their nutritional regime, and the species composition of soil algae were studied. Samples were taken from three different-aged rock dumps of the mines: "South-Donbaska - 3" (rock storage for 40 years); "South-Donbaska - 1" (storage of rock for 52 years), "Trudovska No5 - bis (storage of rock for more than 100 years). The agrochemical parameters of the rock were determined in the samples: pHwater, humus, nitrate nitrogen, mobile phosphorus, exchangeable potassium, particle size distribution. The determination of granulometric fractions of 0–20 cm layer of rock dumps of the mines shows, along with the age, a potential increase of the dump of fine fractions and a decrease in the fraction of stones from 83% in the dump of the South-Donbaska mine, and by 30 to 64.7% in the dump of the Trudovska No. 5-bis. The proportion of the clay fraction is not high in all dumps and it does not exceed 1%, but its appearance indicates the initial stage of a soil structure formation. Soil formation begins with the colonization of mineral rocks with soil algae. The species composition of soil algae, the quantitative accounting were determined by microscopy of a freshly selected soil sample and by cultural methods. Algae species were determined by determinants. In the rock dump, the structure of algal groups becomes more similar to, their structure in the background soils of the territory. The dominance of the representatives of Chlorophyta and Cyanophyta in the rock indicates the steppe process of soil formation. The data obtained contribute to the expansion of the ecological and biological understanding of the initial stages of the formation of soil cenoses.

Opis:: The intensive development of industry generates a number of negative consequences, which leads to an ecological crisis. As a result, the soil on which plant products are grown is polluted by radionuclides, heavy metals, pesticides, and chemicals. That is why in the early 1960s, the alternative farming, which is also called biological, biodynamic or organic, began to develop in Europe. The movement for alternative farming is widely developing in industrialized countries with a high level of chemization of agriculture. Therefore, the proposed topic is extremely relevant in terms of rational nature use, ensuring the sustainable development of territories, as well as food security in Ukraine. The article deals with agroecological assessment of suitability of agricultural land of the Steppe Zone of Ukraine for ecological farming and bases on the modern data from the Kherson branch of the state institution “Institute of Soil Protection of Ukraine”. Spatial modeling of the presence of nutrients in the steppe soil of Ukraine was made by the means of ArcGIS 10.1 product. Taking into account the obtained data and spatial modeling, the territories with soils of limited suitability for ecological farming occupy 67.2% (1194.5 thousand hectares) of the Kherson region, unsuitable soils are located on 16.7% (297.4 thousand hectares) of agricultural land of the Steppe Zone of Ukraine and suitable lands were detected on 16.1% (286.2 thousand hectares) of the territory of the studied lands. The conclusion was made that with the actual availability of lands occupied under ecological farming (4.3% or 75.9 thousand hectares), the territory of the Steppe Zone of Ukraine has a prime potential to increase the area under ecological farming by 4.2 times. Therefore, the article paid attention to ecological farming, taking into account the specifics of the content of trace elements in the steppe soils and their compliance with the methodology for determining whether soils belong to the categories of suitable, limited-suitability and unsuitable for ecological farming.

Opis:: The sewage treatment plant, as a producer of renewable energy, should make every effort to ensure that the biogas used as a fuel meets the quality requirements, including those of the manufacturers of cogeneration units. Such measures necessitate the application of a conditioning process of biogas in order to remove harmful compounds, so that its parameters ensure failure-free operation of engines. The aim of the research was to evaluate the effectiveness of biogas treatment in the A-type installation using the “wet biogas treatment” technology, and in the B-type installation, which is a comprehensive solution comprising sulfur removal as a result of a simultaneous regeneration of the bed with oxygen, removal of siloxanes on activated carbon, cooling and heating of biogas along with its filtration. The analysis of the results of biogas testing for these two installations demonstrated fundamental qualitative differences for the benefit of the installation B, in which the biogas was characterized by a much lower content, mainly of sulfur, hydrogen sulfide, siloxanes and humidity. The introduced pollution indicator of a megawatt hour produced in cogeneration one has confirmed much higher pollution load from the A-type installation. The hybrid solution applied in the work with simultaneous regeneration of the bed has confirmed the efficiency of biogas conditioning. Such a solution contributes to a safe and reliable operation of the cogeneration system for generating energy from a renewable source, which in turn contributes to the optimization of energy.

Opis:: The leather production from paiche skins (Arapaima gigas) has recently grown in Peru, as this allows adding value and earnings from this Amazonian aquaculture waste. The development of this process requires that the tanning techniques could preserve environment as these are meant to take place in Amazonian zones. The present study evaluated the environmental performance of two chrome-free tanning techniques of paiche skins compared with traditional chrome tanning technique, developed at pilot scale by CITEccal Lima. The evaluation was carried out using environmental performance indicators (EPI), analyzed and compared using the grey clustering method, identifying coefficients (σ) respecting to the stablished classes in the study (λ1 – good, λ2 – regular, λ3 – deficient). As result, the two chrome-free tanning techniques showed a better environmental performance than the traditional chrome tanning technique (σ – 0.54, class λ2). The optimized tanning technique applying phenolic compounds had the best environmental performance (σ – 0.98, class λ1), and its values for each environmental performance indicator per 1000 kg of initial processed paiche skin were: 30.0 m3 for water consumption, 815.0 kg of chemical products applied, 2022.7 kWh for energy consumption, 105.5 kg of solid wastes; and from wastewater characterization: 2780.9 mg/L for BOD, 11682.9 mg/L for COD and non-detectable chromium. On the basis of these results, its transfer is recommended, including a wastewater treatment system and environmental management measures implementation.

Opis:: On the basis of the registered indications of the water meter, a study on the size and variability of water consumption on the WULS campus in the academic years 2012/16 is presented. The average specific water consumption at a time when classes are implemented amounted to 26.6 dm³ per student per day for full-time studies student and 19.7 dm³ per student per day for the student part-time studies. During the holiday season, the rates are lower at 18.4 and 11.8 dm³ per student per day, respectively. These ratios were determined without taking the water consumption in the dorms into account. The daily peaking factor amounted (N_d) to 1.36, while the hourly peaking factor (N_h), reached 1.71. Within the week cycle, the highest water consumption was observed in Tuesdays and the lowest – in Sundays. The average Tuesday demands are 40% higher than the Sunday demands. The water consumption peaks during the day occur between 11 a.m. and 1 p.m. as well as 11 p.m. and 1 a.m. The hourly structure of the water distribution in the WULS-SGGW campus is similar to the weekend structure of water distribution in multi-family residential buildings, with the exception of the later occurrence of the evening summit.

Opis:: The objective of this research is to propose an indicator to assess and rank environmental problems caused by production within the food manufacturing sector of Thailand. The factors used to calculate the real benefit included the costs of natural resources, energy and transportation, fertilizer and pesticides, and sanitary and similar service. The highest environmental cost in terms of both natural resources materials and energy and transportation was ice, while the highest environmental cost for fertilizer and pesticides was coconut and palm oil. Confectionery had the highest environmental cost for sanitary and similar services. Overall, real estate gained the highest real benefit, while repair not classified elsewhere had the lowest real benefit for the company. If Thailand uses an indicator of environmental harm, especially within the food manufacturing sector, it could help to formulate efficient policies and strategies for the country in three areas of development, which are social, economic, and environmental development.

Opis:: The article considers the problem of rationing wastewater discharge in terms of environmental risk management, caused by the pollution of waterbodies. The cases of using a simple indicator of water quality in the form of concentration of a substance, as well as a complex indicator of water quality were considered. The relevance of using a complex indicator is caused by the similar effect of various substances on the ecosystem and man. For both cases, the algorithms for determining the permissible composition of wastewater, ensuring compliance with the established standards of natural water quality in the control points of the water body with a given probability, were developed. In the case of using complex indicators in order to unambiguously solve the problem of rationing wastewater composition, permissible concentrations of substances were finally determined by solving the optimization problem. The optimization criterion is the minimum cost of water treatment. The method of ecological standardization of wastewater composition suggested in the article is applicable for the case of normal probability distribution of a substance in wastewater according to data of field measurements.

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.
