The paper presents the results of petromagnetic studies of Lake Sabakty (South Ural, Russia) and their paleoclimatic interpretation. Lakes are an element of modern and ancient landscape. The climatic conditions, environmental features, hydrological and hydrochemical regime are the main factors to determine the features of sedimentation in lakes. It is shown that magnetic parameters can be used for paleoclimatic reconstructions. Particularly informative is the division into para-, ferro-, superparamagnetic magnetic...

Climatic conditions have significantly changed over the last decades. In the middle latitude, the annual precipitation total does not change significantly, but precipitation is unevenly distributed throughout the year. The aim of the research is to investigate the effects of climatic conditions on the dendrological changes of the Royal walnut (Juglans Regia L. var. Chandler) in the period from July to November 2020 in the conditions of the middle latitude of southern Slovakia. This area is characterized by intensi...

Tourism is very vulnerable to climate change. Threats to the sector - direct and indirect - are also increasing extreme weather events, increased costs for insurance and security, water shortages, loss of biodiversity and damage or loss of attractions in tourist places. A study by the World Tourism Organization (UNWTO) in 2016 showed that today, approximately 40% of countries that have prepared national commitments (NDC) recognize tourism either as a priority in their mitigation and adaptation strategies, or as a ...

The goals of this study were to quantify the relationship between population density and climatic variables over Russia. A paired GIS-analysis of the population density layer (a dependent variable) on climatic layers of warmth and water resources and climate severity (independent variables) resulted in a multiple linear bioclimatic model of the population density in Russia. The model explained 38% of the population density variation by climate. We applied our population model to the extreme climate change scenario...

Water resources are vulnerable not only from climate change, but from many other socio-economic drivers of change. According to the Intergovernmental Panel on Climate Change ?Vulnerability is the degree, to which a system is susceptible to, or unable to cope with adverse effects of climate change, including climate variability and extremes?. When a trend towards decreased precipitation and runoff coincides with a trend towards higher water consumption or deteriorated water quality, then the given region or river b...

This paper analyzes the changes of trends in temperature and precipitation in the Azov sea basin. The nature of this territory has undergone major changes. It is an important agricultural and industrial area. The paper considers changes in temperature and precipitation at stations located mainly in the steppe zone. Maximum, minimum, mean air temperature and precipitation trends on a seasonal and annual time scale are evaluated from data recorded at twelve weather stations in the basin of Azov sea during the period...

In the last few years, the climate change has become more and more apparent. In this time the Central European region has experienced disruption of the precipitation layout, serious storms, heatwaves and droughts. Primarily the droughts have let people feel the need for stable and predictable environment. This problem has usually been addressed as a global effort to reduce the production of greenhouse gases, omitting the option of adjusting the environment on much smaller scale. For mitigating the effects of globa...

The updating of the used inflow data to the reservoirs from Annex 1 of the Water Act has been developed for the needs of the Ministry of Environment and Water (MoEW) and for the annual schedules of their water use. Monthly inflow with a certain probability of exceedance (PE - 50%, 75%, 95%) were estimated. The results of the development are uploaded to the MoEW website(https://www.moew.government.bg).In the report are presented and new unpublished results of the annual security assessments - annually inflows with ...

The influence of a number of factors on the condition of small rivers in the Kaliningrad region is considered. It has been shown that deforestation, floodplain cultivation and development, changes in microclimatic conditions, affecting even 20% of the catchment area of the small rivers, significantly specify their ecological state. Since bottom sediments are an indicator of the state of watercourses, their quality also depend not only on factors directly determining composition, but also on factors determining the...

Biological and, of course, economic yield is the result of interaction of internal plant characteristics, namely its genetical and biological potential, and external environmental factors. The efficient plant species, where grapevine is clearly integrated, is a basic limiting factor in the creation of organic material air temperature, which influences vital functions such as nutrients receiving, transpiration, photosynthesis, respiration, and others. In this context, the most often used thermal characteristics are...

In the last years, Romania has suffered large-scale flooding with large areas of land affected by floods, causing major infrastructure damage and leaving behind a significant number of deaths. Climate change and the high frequency of dangerous hydrometeorological phenomena manifested by torrential rains of special intensity produce flash-flood on watercourses due to the rapid concentration of leakage on slopes. These phenomena characterize the vast majority of river basins in Galati County. The pilot area chosen f...

The threats of global change in the 21st century are becoming increasingly significant. Soon, humanity will face not only new climatic phenomena, but also many other related events, which clearly include demographic unrest on many continents. The consequences of these events will be reflected in increased tensions between countries, peoples and groups of people, who will tend to avoid new, in many cases negative, conditions. . The changes will affect not only vulnerable areas, but also regions with a relative calm...

An urgent problem is climate change and marine conditions affecting the formation and evolution of the permafrost zone of the shelf and the continental border of the Russian Arctic. The results of long-term monitoring of the permafrost zone clearly demonstrate the degradation of frozen rocks in both continental and subaquatic conditions of the western sector of the Russian Arctic. Against the background of the observed climate dynamics, the study of geoecological processes becomes especially relevant when drawing ...

In current times of increasing weather extremes and climate change, there is a request for cheap and also high-quality agricultural products. It is important to fertilize soils and improve their physical and chemical properties to increase an agricultural production. To improve soil properties are used various organic materials, and biochar is one of them. Biochar, a product of thermal degradation of biomass, helps to improve the hydro-physical properties of the soil. It is produced from biomass by pyrolysis proce...

Increasing in air temperatures, changes in the precipitation pattern and increased frequency of extreme weather events represent the main characteristics of climate changes in Serbia. Climate changes, according to their characteristics, affect the society, the various sectors of economy and the natural environment. Based on the direct dependence of agricultural production on the climate state, and therefore on climate changes, the agricultural sector represents the most vulnerable sector of economy. In order to de...
