Purpose. In modern conditions of energy consumption growth and a rapid increase in energy prices the actual problem is the development and implementation of energy efficiency programs and resource-saving conversion in to a source to provide the needs of industry and municipal power. The paper aims to solve the urgent problem of energy saving and efficient use of fuel-energy ones and heat supply system optimization on the basis of Uman National University of Horticulture (UNUH). Methodology. The work investigated the process of heating and hot water supply in the course of 2007-2015 years. Implementation of current problems of energy saving is grounded on the scientific-practical and efficient assurance of fuel and energy usage. At the same time energy-saving technologies are viewed as a priority direction of the energy sector development, reduction of man-induced impact on the environment and as a way of improving the competitiveness of the national economy. Findings. Statistical data acquisition and analyzing of gas flow and outside air temperature for nine years was carried out. On the basis of this analysis, the problem was identified and specific targets for its solutions were set. Originality. Scientific novelty lies in solving the problem of energy saving and efficient use of fuel resources in Ukraine through the use of a systematic approach, the methodology development of efficient use of different fuels and optimization of local heating operation, applying contemporary automation and control systems. Firstly it was in detail analyzed and conducted the comprehensive assessment of various factors influence on energy conservation. It takes into account the human factor, professionalism and responsibility of the operators of boilers and their superiors, as well as the relevant control services. Practical value. For UNUH campus hybrid use of solid fuel and gas boilers was carried out. Decentralization of the university heating system has been conducted through the restoration of 350 individual heating systems in residential buildings, remote departments and campus dormitories. The conclusions propose the list of activities upon the real economy of fuel and energy resources, and measures to overcome the economic and political crisis in the country.

The number and sizes of informal settlements are expected to increase drastically in the future, and dramatically so in Sub-Saharan Africa, where migration from rural to urban areas is increasing, and poverty and food insecurity threaten livelihoods. Data sources explaining livelihood factors in informal settlements are scarce, and often highly disputed. In this study, Kibera is investigated, one of the largest informal settlements in Africa. The main aim is to analyze differences in livelihood factors across the villages in Kibera, and to explain some of the existing discrepancies in food security levels among its population. In particular, livelihood factors such as tribe, welfare and trust can explain some of the variation in food security across 12 of the 13 villages located in Kibera. The analyses inform of significant differences across the villages when it comes to, among others, income, food insecurity, ownership of land in rural areas, tribal background and trust levels in strangers and community leads. To reach the millions of people living in informal settlements now, and increasingly so in the future, it is advised that research and implementation go hand in hand, with enhanced understanding of the complexities within rural–urban food systems to ensure solutions that are affordable and accessible to low-income groups. On this pathway to fight poverty and hunger in the future, today’s policies and programs must take such complexities into account to positively contribute to strengthening the resiliency and sustainability of rural–urban food systems by ensuring an increase in welfare levels with zero climate impact.

Introduction. The resources of the business entities of the machine-building complex increasingly determine the importance of developing the components of the internal efficiency of the industry itself and ensuring the national security of Ukraine, since the machine-building complex is the leading branch of the national economy. In this regard, an urgent task is to form a methodological basis based on the concept of the development of the machine-building complex using a system of measures of direct and indirect regulation and improvement of the strategic directions of industrial policy. Aim and tasks. The purpose of the paper is to substantiate the essential characteristics of the economic security of the machine-building complex, as well as to study the approach to implementing the concept of the development of the machine-building complex based on the application of methodological contexts. The paper examines the essential and practical characteristics of implementation the concept development of the machine-building complex in the context of methodological basis based on safety-related conditions. Results. The evaluation of the effectiveness of the implementation of the existing concept using the model for selecting target indicators is substantiated, as a result of which the main vectors for ensuring the safety of machine-building enterprises in modern conditions of challenges and threats are identified. In addition, three design stages of the implementation of this concept are characterized and the features of ensuring the relevant safety components in the conditions of the intensification of the development of the machine-building complex are studied. Conclusions. A distinctive feature of the management of the economic security system of machine-building enterprises is the ability to use operational, tactical, strategic, and preventive mechanisms for diagnosing, stabilizing, and ensuring the economic security of machine-building enterprises. The proposed concept allows assessing the prospects for the development of a machine-building enterprise, developing its tactics and strategy, and reducing the consequences of financial crises and the negative impact of new threats and dangers based on the practical application of the concept of developing the complex under study using predetermined methodological contexts.

Abstract The article proves the necessity and expediency of using financial leasing by extractive industry enterprises to minimize the cost of purchasing, using, maintaining equipment and maintaining production capacity. Foreign and domestic financial leasing practices analyzed and their direct impact on the development of the country’s economy is determined. Financial leasing will become more accessible and understandable for enterprises of different sectors of the economy after the entry into force of the Law of Ukraine “On Financial Leasing”. The analysis of the value of the concluded financial leasing agreements by sectors of the economy carried out and their basic tendencies defined. It is determined that the volume of concluded financial leasing agreements by extractive industry enterprises has a small share in comparison with other branches of economy. The analysis of the effectiveness of structural changes confirm the low demand for financial leasing by extractive industry enterprises. It is determined that the use of financial leasing by extractive industry enterprises will expand existing production, introduce the latest technologies, minimize costs for the purchase, use, maintenance and upgrade of equipment and means of production.
