Актуальність теми обумовлена необхідністю визначення змін гідрологічного, гідрохімічного та гідроекологічного стану водних об’єктів України в умовах антропогенного впливу та глобального потепління з метою оптимізації управління водними ресурсами. Метою досліджень є вивчення впливу змін клімату на якість водних ресурсів річки Псел залежно від температурного режиму і кількості опадів у Полтавській області. В роботі розглянуто вплив глобального потепління, а саме зміни температурного режиму повітря та кількості опадів на якісні та кількісні характеристики річки Псел на території Полтавської області. За допомогою статистичних методів доведено існування кореляційного зв’язку між параметрами клімату та якісними характеристиками водойми. Результати досліджень доцільно враховувати під час розробки схем адаптації регіону до умов глобального потепління та у процесі керування водоохоронною діяльністю в басейні річки Псел. Практичне значення результатів полягає в наданні оцінок змін характеристик водних ресурсів річки Псел, виявленні наслідків змін клімату на гідрологічний, гідрохімічний та гідроекологічний режими річки, встановленні взаємозв’язків між підвищенням середньорічної температури води та кисневим режимом водойми. Результати роботи у подальшому будуть використані під час розроблення регіональних екологічних програм та схем оптимізації поводження з водними ресурсами. The climate of the planet is a complex system that changes as a result of processes of interaction between the atmosphere, the ocean and man. These elements are in a balanced equilibrium, which is now being destroyed by man's human activity. The urgency of the theme is due to the necessity of determining changes in the hydrological, hydrochemical and hydroecological state of water objects of Ukraine in the conditions of anthropogenic influence and global warming in order to optimize the management of water resources. The purpose of the research is to study the impact of climate change on the quality of water resources of Psel river, depending on the temperature regime and rainfall in Poltava region. The paper examines the effects of global warming, namely changes in the temperature regime of air and rainfall on qualitative and quantitative characteristics of Psel river in the territory of Poltava region. Using statistical methods, the existence of a correlation between climate parameters and qualitative characteristics of the reservoir has been proved. The results of the research should be taken into account when developing the schemes of adaptation of the region to the conditions of global warming and in the management of water protection activities in the basin of Psel river. The practical value of the results is to provide estimates of changes in the characteristics of the water resources of Psel river; detecting the effects of climate change on the hydrological, hydrochemical and hydroecological regimes of the river; establishing interrelationships between raising the average annual water temperature and the oxygen regime of the reservoir. The results of the work in the future will be used in the development of regional environmental programs and schemes for optimizing the management of water resources.

Much of the earth’s surface is covered by water. As was pointed out in the 2020 edition of the World Water Development Report, climate change challenges the sustainability of global water resources, so it is important to monitor the quality of water to preserve sustainable water resources. Quality of water can be related to the structure of water crystal, the solid-state of water, so methods to understand water crystals can help to improve water quality. As a first step, a water crystal exploratory analysis has been initiated with the cooperation with the Emoto Peace Project (EPP). The 5K EPP dataset has been created as the first world-wide small dataset of water crystals. Our research focused on reducing the inherent limitations when fitting machine learning models to the 5K EPP dataset. One major result is the classification of water crystals and how to split our small dataset into several related groups. Using the 5K EPP dataset of human observations and past research on snow crystal classification, we created a simple set of visual labels to identify water crystal shapes, in 13 categories. A deep learning-based method has been used to automatically do the classification task with a subset of the label dataset. The classification achieved high accuracy when using a fine-tuning technique.

Climate change has an important impact on the environment. As it degrades the quality of water, soil, and area, it also spreads the distribution of many toxic elements, specifically heavy metals and pesticides. The impact of climate change on contamination with heavy metals and pesticides has been well investigated and discussed. The influence of these elements on human health is obviously exacerbated following their extended distribution. Moreover, a wide range of health problems have been associated to such intoxication, among which impairment and dysfunction of the nervous system are prominent. In this chapter, the authors will shed light on two most common neurological diseases such as epilepsy and stroke affecting people worldwide arising from food and water contaminations, mainly with heavy metals and pesticides.

Abstract. In the threshold of the appearance of global warming from theory to reality, extensive research has focused on predicting the impact of potential climate change on water resources using results from Global Circulation Models (GCMs). This research carries this further by statistical analyses of long term meteorological and hydrological data. Seventy years of historical trends in precipitation, temperature, and streamflows in the Great Lakes of North America are developed using long term regression analyses and Mann-Kendall statistics. The results generated by the two statistical procedures are in agreement and demonstrate that many of these variables are experiencing statistically significant increases over a seven-decade period. The trend lines of streamflows in the three rivers of St. Clair, Niagara and St. Lawrence, and precipitation levels over four of the five Great Lakes, show statistically significant increases in flows and precipitation. Further, precipitation rates as predicted using fitted regression lines are compared with scenarios from GCMs and demonstrate similar forecast predictions for Lake Superior. Trend projections from historical data are higher than GCM predictions for Lakes Michigan/Huron. Significant variability in predictions, as developed from alternative GCMs, is noted. Given the general agreement as derived from very different procedures, predictions extrapolated from historical trends and from GCMs, there is evidence that hydrologic changes particularly for the precipitation in the Great Lakes Basin may be demonstrating influences arising from global warming and climate change.

Ecosystem vulnerability increases significantly when anthropogenic factors overlap with the effects of adverse climate change, which together negatively affect biodiversity and ecosystem functioning. According to ADB forecasts, the inflow to the lower reaches of the Amu Darya will decrease by 26-35% by 2050. The combined effect of higher water demand and lower inflow will increase the current water shortage - the annual water shortage will increase to 50% of the total demand. In connection with the projected changes, the current state of water resources of the Amu Darya river, as well as the need for the socioeconomic development of the region, the task of assessing the projected impact of climate change on the availability and quality of water resources becomes urgent.

Complex chemical-analytical and microbiological studies of the state of water, soil grounds and bottom sediment of the industrial zone of city of Khabarovsk were carried out. It was found that petroleum prodacts are the main environmental pollutant of the study area. The impact of runoff from the industrial zone on the quality of water and bottom sediments of the Amur river is manifested in an increase in their content and number of indicator groups of bacteria in the zone of impact of the small river Kurcha-Murcha draining the territory of the industrial zone. The oil content in the Kurcha-Murcha river at the exit from conduit is 20 MPC. The degree of soil contamination varies from “increased-background” to “strong”. The amount of oil products in the bottom sediments of the Kurcha-Murcha and the Amur river (below the mouth of the Kurcha-Murcha river) is defined as "dangerous" and "strong", respectively.

The climate of Sri Lanka has been fluctuating at an alarming rate during the recent past. These changes are reported to have pronounced impacts on the livelihoods of the people in the country. Water is central to the sustainable functioning of ecosystems and wellbeing of mankind. It is evident that pronounced variations in the climate will negatively impact the availability and the quality of water resources. The ecosystem-based adaptation (EbA) approach has proved to be an effective strategy to address the impact of climate change on water resources in many parts of the world. The key aim of this paper is to elaborate the wide range of benefits received through implementation of EbAs in field level, watershed scale, and urban and coastal environments in the context of Sri Lanka. In addition, this paper discusses the benefits of utilizing EbA solutions over grey infrastructure-based solutions to address the issues related to water management. The wide range of benefits received through implementation of EbAs can be broadly classified into three categories: water supply regulation, water quality regulation, and moderation of extreme events. This paper recommends the utilization of EbAs over grey infrastructure-based solutions in adaptation to climate change in the water management sector for the developing region due its cost effectiveness, ecofriendliness, and multiple benefits received on long-term scales. The findings of this study will unequivocally contribute to filling existing knowledge and research gaps in the context of EbAs to future climate change in Sri Lanka. The suggestions and opinions of this study can be taken into account by decision makers and water resources planning agencies for future planning of actions related to climate change adaptation in Sri Lanka.

<p>Climate change raises many questions about the future availability of water resources in West Africa. Indeed, water in this region is a fundamental element for many socio-economic activities. This study proposes an assessment of the impact of climate change on the hydrology of the Faleme basin, located in the Sahel (West Africa). The applied methodology consists in calibrating and validating the hydrological model GR4J before simulating the future evolution of flows in this catchment under of 1.5 and 2°C global warming.  Observed rainfall, potential evapotranspiration (PET), and river flows were used for calibration and validation of the GR4J model. Furthermore, output of three regional climate models (DMI-HIRHAM, SHIM-RCA, and BCCR-WRF) were bias corrected with the cumulative distribution function-transform (CDF-t) before used as input to the GR4J hydrological model to simulate future flows at the watershed scale. During the historical period the results shows a good correspondence between the simulated flows and those observed during calibration and validation, with Nash–Sutcliffe efficiencies (NSE) greater than 70%. Projections show a general increase in mean annual temperature and PET; a decrease in mean annual rainfall is projected by the DMI-HIRHAM, BCCR-WRF models and the overall mean; while a slight increase is noted with the SMHI-RCA model. As for future flows, a downward trend in annual and monthly average flows is expected in the two sub-basins of the Faleme (Kidira and Gourbassi) with input from the DMI-HIRHAM, BCCR-WRF models and the overall mean; however,  the GR4J forced by the SMHI-RCA model output, project increased flows. Furthermore, the decrease is more pronounced at Gourbassi sub-basin than at Kidira sub-basin. Thus, recommendations were made to mitigate the likely impacts of climate change on socio-economic activities that use water resources.</p>
