Published: January 2023

Abstract
In the last few years as the budget for the road sector has been decreasing in Latvia, the number of road pavement structure reinforcement projects has been increasing. In order to ensure the long-term viability of the road it is necessary to assess the load-bearing capacity of the existing road structure and the subgrade. During the geotechnical research, the load-bearing capacity of the existing base layers is assessed using static plate test. However, the accuracy of the results is strongly influenced by the thickness of the existing asphalt layer and the size of the dismantled asphalt area. In order to determine the load-bearing capacity of the existing road base in the deeper layers, the engineer performs a subjective experience-based interpretation that is not based on mathematical calculations. With the development of geotechnical survey equipment and engineers’ understanding of the bearing capacity of the subgrade, it is also possible to use other field research methods, such as probing and interpretation of their data. Various software’s for soil calculations have been developed worldwide. With the help of software’s, it is possible to evaluate the properties of soil layers, predict deformations and develop reinforcement solutions, however, the obtained results do not reflect the basic bearing capacity, which is expressed in MPa units. It is planned to develop a Finite Element Method simulation of static plate test based on the values of the soil layer parameters obtained from the interpretations of the probe data and to compare the results with the static plate test performed on site. The aim of the study is to determine whether the load-bearing capacity of the existing base can be accurately determined by finite element calculations - a simulation of a static plate test based on the physical-mechanical properties of the soil determined during the geotechnical survey.

Authors: Amare V , Smirnovs J 
Published: January 2023

Abstract
Traffic organization must be safe, but according to traffic accident data, the highest number is at intersections. Different intersections are evaluated based on various criteria - road throughput, conflict points, number and severity of road traffic accidents. There are many different types of intersections in the road network, each of them is suitable for certain road parameters in the road network. In the main road network of the State of Latvia for the period 2017-2019, data was collected and places where road traffic accidents often occur were evaluated. Where one of the most important tasks was to find a rational way to improve safety without losing the importance of the road. The aim of this work is to analyze the impact of different intersections on the road network, as well as to provide recommendations for a safe consistent road network based on actual data.

Abstract
Elephants have long been observed to grip objects with their trunk, but little is known about how they adjust their strategy for different weights. In this study, we challenge a female African elephant at Zoo Atlanta to lift 20–60 kg barbell weights with only its trunk. We measure the trunk’s shape and wrinkle geometry from a frozen elephant trunk at the Smithsonian. We observe several strategies employed to accommodate heavier weights, including accelerating less, orienting the trunk vertically, and wrapping the barbell with a greater trunk length. Mathematical models show that increasing barbell weights are associated with constant trunk tensile force and an increasing barbell-wrapping surface area due to the trunk’s wrinkles. Our findings may inspire the design of more adaptable soft robotic grippers that can improve grip using surface morphology such as wrinkles.
Quantifying global carbon dioxide removal deployment

Published: January 2023

Abstract
Despite the importance of carbon dioxide removal (CDR) in most climate change mitigation scenarios that limit warming to well below 2 °C, the study of CDR is still a nascent field with basic questions to be resolved. Crucially, it is not known how much CDR is currently deployed at a global scale, nor how that compares to mitigation scenario estimates. Here, we address this problem by developing an estimate of global current CDR activity. We draw on national greenhouse gas inventory data combined with CDR registries and commercial databases to estimate that global anthropogenic activity presently generates ∼1985 MtCO2yr−1 of atmospheric removals. Almost all of these—1983 MtCO2yr−1—are removals from land-use, land-use change and forestry. Non-land-management CDR projects such as bioenergy with carbon capture and storage, direct air capture with carbon capture and storage and biochar remove only about 2 MtCO2yr−1. We compare this estimate with Shared Socioeconomic Pathways projections of CDR deployed in ‘well-below 2°C’ mitigation pathways. In so doing we demonstrate current CDR deployment would need to grow exponentially to keep the world aligned with most ‘well-below 2°C’ scenarios, which see CDR deployment growing between 75% and 100% per year between 2020 and 2030, adding ∼300–2500 MtCO2 in total CDR capacity. To conclude we discuss uncertainties related to our estimates, and suggest priorities for the future collection and management of CDR data, particularly related to the role of the land sink in generating CDR.
Quantifying the fragility of coral reefs to hurricane impacts: a case study of the Florida Keys and Puerto Rico

Published: January 2023

Abstract
Ecosystems like coral reefs mitigate rising coastal flood risks, but investments into their conservation remain low relative to the investments into engineered risk-mitigation structures. One reason is that quantifying the risk-reduction benefits of coral reefs requires an estimate of their fragility to severe stresses. Engineered structures typically have associated fragility functions which predict the probability of exceeding a damage state with the increasing loading intensity imposed by a stressor, like a hurricane. Here, we propose a preliminary framework for capturing the fragility of coral reefs towards hurricanes in an analogous way to that of an engineered structure. We base our framework on Disturbance Response Monitoring data collected in the Florida Keys and Puerto Rico following hurricanes Irma and Maria. We first establish a qualitatively consistent correlation between hurricane impacts and coral mortality rates using two surveys of coral health. We focus specifically on stony coral mortality as a metric for reef damage, simplifying the effect of coral morphology into a single quantitative index at the site scale. To quantify the loading intensity of a hurricane, we propose a Hurricane Wind Exposure Time that captures spatial variations in the exposure of different coral reef sites to hurricane force winds. We ultimately derive a simple empirical fragility function for the Florida Keys and Puerto Rico to support side-by-side comparisons of the cost-effectiveness of a coral reef and engineered solutions to flood risk reduction in these regions.

Abstract
The article is devoted to determining the role of the information sector of the economy in the new conditions of ensuring the sustainable development of the economic system. The article determines that the largest influence on the GDP per capita of Ukraine is exerted by the indicator of realized Internet services. This proves the fact that today the consumption of information and communication services plays a leading role in the economic growth of the country. And therefore, there is an opportunity not only to influence the growth of GDP by creating conditions of a technical and informational and communication nature, but also to determine the prerequisites for the growth of national income based on the study of consumer needs and their transformations in the conditions of digitalization. In accordance with the concept of sustainable development, the indicator of the usefulness of information needs is not their volume and the desire of economic subjects to use them, but the characteristics of reliability, completeness, accuracy, novelty, efficiency. Along with this, it was noted that the comprehensiveness and unrestrained consumption leads to social irresponsibility, massification, negative effects on the ecological situation of the environment, the undermining of sustainable mechanisms of the existence of civilization as a whole, which requires the justification of alternative approaches of “frugal” and “restrained” consumption. The implementation of prosumerism approaches is defined as an alternative way to building an information and network economy of sustainable development.

Abstract
The oxygen-producing function of urban forests is an integral factor in creating favourable living conditions for the population in an urbanized environment. Managerial decisions aimed at the development of environmental potential in urban forests shall be based on sustainable development goals and ensure the balanced use of their ecosystem functions. As a result of the research, quantitative values of the oxygen productivity of urban forests in Kyiv have been computed. Also, we have analysed the influence of the main biometric characteristics of stands on the intensity of their oxygen production capacity. The informational basis for evaluating the oxygen productivity of urban forests consists of research data that reflects the silvicultural characteristics of more than 14,000 forested plots featuring different species composition, age, and site index class, growing in different types of conditions. As a methodological basis, we have applied the semi-empirical method, which involves assessing the net primary production of ecosystems. The proposed quantitative values of oxygen productivity in Kyiv’s urban forests serve as an information component in forming a sustainable development strategy for the preservation and extended restoration of forest ecosystems in the region.

Abstract
Methodical approaches to calculating the economic efficiency of natural resources use are considered. The characteristics of water services regulation in Ukraine are given. Economic indicators of regional development in the Vistula River basin are investigated. The dynamic analysis of revenues for special water use and expenditures for water resources in the Vistula River basin is carried out. Revenues to the state and local budgets were investigated in terms of rent payments, environmental tax, rent and special use of fish and other aquatic bioresources. To calculate the economic efficiency, the state expenditures under the budget program “Operation of the state water management complex and water resources management” in the Vistula River basin area were used. The obtained indicator was improved by taking into account the environmental component. Expenditures in the context of capital and current investments from the state and local budgets for environmental programs in the field of water resources protection were analyzed. The indicator of reduced costs for water resources in 2020 is formed. It is proposed to assess economic efficiency through the indicator of the level of coverage of the reduced costs of water resources.

Abstract
The article examines the economic aspects of the production of electrical engineering and electricity at traditional and renewable energy facilities. The authors emphasized that Ukraine has great potential for the development of wind and solar energy capacities, but the relatively high current price of such technologies compared to conservative sources of electricity generation makes new power generation capacities from RES twice as expensive. The authors consider, improving energy efficiency could significantly reduce the growth in energy consumption: according to the International Energy Agency, the implementation of measures to improve energy efficiency on a global scale by 2030 would lead to an increase in energy consumption by 40%, while failure to implement these measures would mean a 60% increase in demand. It is proved that in Ukraine the most promising direction is the use of solar energy. The authors focused on the direct conversion of wind and solar energy into direct current electrical energy. The possibility of converting wind and solar energy into thermal energy without preliminary concentration of the solar radiation flux for heating the coolant and subsequent supply to heating objects has been proved. It was noted that a significant modernization of power plants using renewable energy sources or the construction of additional capacities (for an amount exceeding 50% of their initial cost) after 2014, 2020 led to a reduction in the rates of the “green” tariff for the entire power plant by 10%, 20% respectively and will lead to 2024 by 30%.

Abstract
The article presents the results of an analysis of the number, frequency and intensity of tropical nights in Ukraine. We have selected such weather stations that are located at different latitudes and correspond with the north, west, east, and south as well as the central part of Ukraine. This was done in order to analyse the differences in tropical nights across latitudes. Also we have weather stations located at the approximately one latitude to analyse how tropical nights vary in longitude. Data from weather stations for 1976-2019 were under analysis. We can say that the increase in the minimum air temperature during summer is on the whole territory of Ukraine. This leads to the fact that since the mid-1990s tropical nights begin to be observed in the east of Ukraine, as well as in the south. After 2000, tropical nights also have begun to be observed in the centre and even in the west of Ukraine. Between two half-periods (1976-1997 and 1998-2019) the increase of number of tropical night events in the south of Ukraine (up to 300 cases) is much more significant than the increase in their number in the northwest (up to 20 cases). As well as the frequency, the intensity of tropical nights also increases. There are cases with minimum daily air temperatures above 25°C. The analysis of the North Atlantic Oscillation (NAC) and the Mediterranean (Cairo-Algeria) indices in the context of explaining the tropical night’s occurrence in Ukraine turned out to be quite effective.

Published: January 2023

Abstract
The processes of modernization of the environmental safety system in the context of achieving sustainable development are actualized by global problems that arise as a result of man-made load on the atmospheric air. Among the cities of Ukraine, the capital occupies one of the first places in terms of pollution. In the process of ecological modernization in order to improve air quality, it is necessary to have detailed information about the level of pollution, pollutants, sources of their formation, changes in time and space, etc. Traditionally, monitoring of air quality in the capital is carried out by different organizations, which assess air quality only by the content of particles with a size of 1-10 microns, which is not enough for a complete analysis and assessment of the state of pollution. The most acceptable direction for the further development of the air quality monitoring system in Kyiv is to increase the coverage of the territory of the capital with a modern network of monitoring points of the Kyiv City State Administration, which in the future will become an information basis for making the necessary management decisions to ensure the sustainable development of Kyiv.

Published: January 2023

Abstract
Environmental sustainability and its achievement at the national level is one of the key strategic development goals for most countries who are the largest environmental pollutants. Environmental sustainability implies the maximum possible reduction of negative environmental impact through the development of green energy, the increase in energy efficiency, the rational use of natural resources, the introduction of the principles of circular economy and increasing public awareness of environmental protection and climate conservation. There are many administrative tools to encourage enterprises worldwide to switch to a more environmentally friendly direction of its operating and development, among which is the introduction of international standards and subsequent certification of the enterprises. In addition to such obvious advantages as the introduction of effective environmental management systems, compliance with requirements in the field of environmental audit and monitoring, certification allows to increase credibility in the face of consumers and partners that leads to a favorable reputational effect. The objective of this study is to review and analyze the family ISO 14000 standards and assess their role in achieving environmental sustainability of enterprises. The authors determined the degree of influence of groups of standards on the achievement of environmental sustainability and identified their benefits and drawbacks.

Abstract
Effective implementation of environmental policy is important for the sustainable development of the country. Implementation of strategic nature protection tasks is entrusted to relevant organizations. Institutions that regulate water use occupy a special place among them. The functioning of such organizations depends on human resources. The research mechanism for the priority of human resources management factors for employees of the water management complex was developed on the basis of a combination of sociological survey and matrix analysis. The development was tested on the example of the Rivne Interdistrict Water Management. 75% of the administrative and management personnel of the organization were interviewed. The most important thing for employees of the water management organization is the amount of monetary incentives and the timeliness of their payment. Almost all respondents rated them as high as possible on a 5-point scale. For the majority of respondents, social and psychological comfort in the organization is also of great importance. Such components of personnel management as proper working conditions and the possibility of independent choice of vacation time, mutual relations with colleagues and the attitude of the immediate supervisor received a high rating of importance. Interrelated factors such as the possibility of realizing one’s own abilities and the nature of work, opportunities for career and professional growth, and self-regulation of the working time schedule are also significant.
