“…Therefore, when analyzing the anthropogenic impact on a water body and the absence of such sources of pollution, monitoring for SO 4 2− and Cl − can be omitted [63,64]. The presence of phosphates in high concentrations in water is associated with anthropogenic impacts [65]. Elevated phosphate concentrations cause the phenomenon of eutrophication and, consequently, an increase in suspended solids.…”

Various human activities have been the main causes of surface water pollution. The uneven distribution of industrial enterprises in the territories of the main river basins of Ukraine do not always allow the real state of the water quality to be assessed. This article has three purposes: (1) the modification of the Ukrainian method for assessing the WQI, taking into account the level of negative impact of the most dangerous chemical elements, (2) the modeling of WQI assessment using fuzzy logic and (3) the creation of an artificial neural network model for the prediction of the WQI. The fuzzy logic model used four input variables and calculated one output variable (WQI). In the final stage of the study, six ANN models were analyzed, which differed from each other in various loss function optimizers and activation functions. The optimal results were shown using an ANN with the softmax activation function and Adam’s loss function optimizer (MAPE = 9.6%; R2 = 0.964). A comparison of the MAPE and R2 indicators of the created ANN model with other models for assessing water quality showed that the level of agreement between the forecast and target data is satisfactory. The novelty of this study is in the proposal to modify the WQI assessment methodology which is used in Ukraine. At the same time, the phased and joint use of mathematical tools such as the fuzzy logic method and the ANN allow one to effectively evaluate and predict WQI values, respectively.

“…Every new development involves certain costs which can certainly be counted as negative effects, e.g., consumption of natural resources, space, or green areas. However, the new development can generate compensation in terms of value and utility that will benefit the local community, as well as future inhabitants [98,99]. The issue of negative externalities is extremely important when trying to explain why the cost of a bad project is not always considered during the planning of a development.…”

The quality of the housing environment (HE) is an important issue that has a direct impact on the life of inhabitants. Aiming for quality in residential architecture begins with a well-designed HE, with the designing process being a value that is difficult to evaluate. Nowadays, a well-designed HE takes into account the energy efficiency of a building. An appropriate degree of thermal comfort, which is required by inhabitants, needs to be considered at the design stage. Designers can use building certification programs and multi-criteria analysis to motivate investors to construct buildings in accordance with energy efficiency requirements. These systems respond to the needs of energy efficiency, thermal comfort, sustainable heating, and ventilation. Defining ways and methods to evaluate quality in architectural projects will allow the value of the HE to be improved. For this purpose, a multi-criteria analysis of five systems that can be used to evaluate HE quality and energy efficiency in a temperate climate was conducted: (1) Building For Life 12, (2) Home Quality Mark, (3) Housing Quality Indicators, (4) Système D’évaluation De Logements (Sel), and (5) NF Habitat-NF Habitat HQE. This analysis concerned information about the systems, their applicability in practice, and the applied assessment measures. The article shows that the quality of the HE consists of specific factors that can be distinguished and indicated by evaluation systems. As a result of the carried out assessment of the housing environment, 13 original categories of building assessment criteria were defined. The results of the conducted analysis indicated that it is possible to: (i) identify factors for the improvement of HE quality; (ii) prepare objective systems for the measurement of the HE; and (iii) use such systems in practice, e.g., in the design industry, real estates, and public administration. Moreover, the systems can be used in legal regulations for updating urban policies.

“…The Volyn Polissia waterways, especially the small rivers, are exposed to significant anthropogenic pressure [4][5][6][7]. The quality of the surface water does not meet the requirements of the EU Water Framework Directive, and their current state is assessed as critical [8]. In the border areas of Volyn Polissia, small rivers with their swampy catchment area and preserved forest vegetation form the water content, hydrochemical regime, hydroecological state and water quality of the basins of medium and large tributaries of the Prypiat.…”

The assessment of the transformation level in the Buniv River basin (Ukraine) transformation was performed. Substantiates the need to improve the monitoring system within the river basin, as the main tool for assessing and predicting changes in the aquatic ecosystem and managing the processes of its anthropogenic. The research methods included on-site investigations, laboratory and analytical studies, data processing using GIS technologies. A topographic survey of the Buniv River’s floodplain within the village of Rokytne town was performed. The on-site investigations included field surveys and water sampling at 4 control sites on the Buniv River for 13 quality indicators. The analysis of the obtained cartographic models indicates a significant anthropogenic transformation of the natural landscapes. A significant part of the watercourses of the Buniv River basin was once directed and transformed into main canals of the meliorative systems. This causes the formation more dangerous flood flow.
