TL;DR: In this article, the authors explore public-private partnerships as a tool for economic development of rural economies in developing countries and countries with economies in transition in order to ensure sustainable use of nature and increase public welfare of rural communities through the added value chain.
Abstract: Purpose. The aims of this paper are (i) to explore public-private partnerships as a tool for economic development of rural economies in developing countries and countries with economies in transition in order to ensure sustainable use of nature and increase public welfare of rural communities through the added value chain; (ii) to develop proposals for the implementation of public-private partnerships on land management and land use in Ukraine. Methodology / approach. The methodological approach involves study of the world’s PPP practice in land management and land use (including the use of land in forestry), study of the connections between PPP projects and scientific approaches to the concept of sustainable development and the added value chain, as well as analysis of domestic scientific bibliography, which relate to the subject of this study. Results. The authors found that the declared priorities of the Agenda for Sustainable Development until 2030 require the application of integrated approaches. In particular, the programme in the mechanism of sustainable development management in the form of PPP to ensure sustainable use of nature and increase the social welfare of rural communities. Because the programme approach here involves investing in natural resources and environmental protection and should cover the entire value chain, which directly or indirectly affects the efficiency of natural rural assets, as well as the use and application of innovative technologies. Originality / scientific novelty. It is substantiated that progress in achieving the declared priorities, in particular in the field of environmental protection, growth of public rural welfare, etc. is possible only in a combination of strengths of all PPP partners, which will eliminate the shortcomings and weaknesses of rural communities. In contrast to existing approaches to the development of the land use economy of rural territories, the basis of the synergy of the parties to PPP is a special natural resource – land, which performs environmental, economic, legal and socio-cultural functions, and determines the form and content, which actually builds sustainable development, including rural. A wide range of PPP forms has been further developed, varying in the degree of involvement and risk taken by the private party in relation to the development of the land use economy of rural territories. The approach to the value chains organization in the development of PPP projects on land management and land use and providing security of land use in terms of taking into account the land use of farmers, formed on different rights, has been improved. The author’s project PPP in the production of pellets a private investor in lumber logging waste provided by some state-owned enterprise both subject to the extension of the moratorium and without its effect is developed. Practical value / implications. The authors’ research shows that the introduction of the value chain in the mechanism of public-private partnership will lead to significant effective changes in the development of the land use economy, in particular of rural territories. Namely, with the use of appropriate policies it will ensure the provision of sustainable use of natural resources and growth of public welfare, in particular rural communities. This approach allows to involve all stakeholders (government, community, business) for effective management of natural assets in general and agriculture in particular and will increase their level of capitalization and investment attractiveness.

TL;DR: In this article , the potential of renewable energy sources in the energy sector of the country of Ukraine has been assessed using the Global Atlas of the International Renewable Energy Agency (IRENA) to support planning of technologies for the use of energy from biomass.
Abstract: The scientific novelty of the results presented in this article is to substantiate and expand the possibilities of using global and local geographic information systems (GIS) to assess the potential of renewable energy sources in Ukraine. GIS analysis focused on key resource parameters can help identify territories for development of renewable energy sources and assess of their possible technical potential, as well as the possibility of effective integration of technologies for the use of renewable energy sources in the energy sector of Ukraine. In this paper the possibilities for using geographic information systems to assess the potential of renewable energy sources in Ukraine are analyzed. The possibility of using the Global Atlas of the International Renewable Energy Agency (IRENA) to support planning of technologies for the use of energy from biomass is analyzed. The data can point to large-scale programs and applications in relation to key parameters (quality resources, transmission distance, population density, terrain and site protection), helping identify additional areas for development of renewable energy sources and give an approximate assessment of technical potential. It is determined that the software products of IRENA are able to support national and regional planning of renewable energy technologies, help establish the viability of future renewable energy facilities and help project developers identify and analyze promising facilities for the implementation of technologies using renewable energy. The application of geographic information systems of Ukrainian web resources (“UA MAP”) for assessing the potential of renewable energy sources and energy efficiency in Ukraine is been analyzed. The scientific novelty of the results lies in applying global and local GIS for comprehensive assessment of the potential and effectiveness of the use of regional non-traditional and renewable energy resources on the territory of Ukraine. This makes it possible to assess the possibilities of generating additional electric and thermal power for the needs of the regions of Ukraine using non-traditional and renewable energy sources. A comprehensive methodology for the use of GIS is proposed for assessing the potential of non-traditional and renewable energy sources at the regional level in Ukraine, taking into account energy, environmental and socio-economic factors affecting the placement of non-traditional and renewable energy facilities.

TL;DR: In this article, the authors outline the current problems and contradictions in the waste management system in Ukraine from the standpoint of ensuring the ecological stability of the Eastern European region and propose the stage of transition to recirculating recycling technologies of waste.
Abstract: The article outlines the current problems and contradictions in the waste management system in Ukraine from the standpoint of ensuring the ecological stability of the Eastern European region. The accepted paradigm of creating a recirculating economy is provided by a territorially balanced waste management system in the regions of Ukraine. The coefficient of territorial provision of utilization capacities has been proposed and tested, which allowed the evaluation of their existing potential integrally, and determined the formed regional disproportions between waste generation and utilization. In order to solve the existing imbalances in Ukraine in a comprehensive way, the stage of transition to recirculating recycling technologies of waste is proposed. The mathematical formalization of the problem of waste management in Ukraine specifies the space-time parameters of solving the problem of the system balance and provides the variability of input and output parameters for solving empirical problems.

TL;DR: In this paper, the background spatial-factorial patterns of distribution of quantitative and qualitative indicators of groundwater sources and surface waters within the upper part of the Prut River that belongs to the Danube River basin were analyzed.
Abstract: The study solved the problem of analyzing the background spatial-factorial patterns of distribution of quantitative and qualitative indicators of groundwater sources and surface waters within the upper part of the Prut River that belongs to the Danube River basin. The studies have been conducted within the Carpathian National Nature Park, located on the northeastern slopes of the Ukrainian Carpathians. The basic regularities and peculiarities of the distribution of springs in the researched territory have been studied by means of factor analysis of the set of estimation parameters and the relationships between them. Patterns of changes in the concentrations of the natural components of the qualitative composition of the hydro-ecosystem have been found, depending on the altitude of the terrain. Similar data has been obtained in the analysis of the relationship between the average geometric components of the chemical composition of natural waters and the length of the river. Trend lines and equations have been obtained, which can be used to determine the background normative values of natural water components along the length of the stream and the altitude of the basin for individual seasons and phases of water. In this paper, for the first time, the functional natural pattern of hydro-ecosystems of the upper part of the Danube basin within the northeastern slopes of the Ukrainian Carpathians is shown to increase its qualitative potential with increasing absolute altitude above sea level for nature conservation territory.
TL;DR: In this article , a survey of the owners of local tourist accommodation facilities in the Ukrai-Nian Carpathians showed that 17.5% use surface sources, 48.8% use underground sources, 32.4% use mixed sources, 56.2% dispose of sewage disposal without proper water reclamation.
Abstract: The Carpathian region is distinguished by a high tourist flow and variety of hotels. The need for consumption of qual ity drinking water for tourists and local population is determined. Underground sources and wells constitute a water supply of accommodation facilities in this region. The issue of drinking water quality in the Carpathians remains poorly studied. It is necessary to realize the landscape, the content of heavy metals in the rocks, the differences in elevation, and tourist flow that can cause diffusion pollution. Sources of water supply in the tourist area of the Ukrai nian Carpathians are the subject of the article. The sociological survey of the owners of local tourist accommodation facilities showed that 17.5% use surface sources, 48.8% use underground sources, 32.5% use mixed sources, 56.2% of respondents dispose of sewage disposal without proper water reclamation. We took samples of drinking water from sources, wells in this region and analyzed such indicators as pH, temperature, altitude, nitrates and nitrites, phos -phates, ammonium, and mineralization. Sensafe’s visual membrane tests for drinking water determined heavy metals such as Cu, Ni, Co, Zn, Cd, Hg, Fe in the water samples. The functional dependence of the content of heavy metals and the altitude zonation of drinking water sources for the region іs described by the equation y = -0.059ln( x ) + 0.4219.
