It has been scientifically proven that aluminum, more than other materials, meets the requirements of production, storage and processing of various foods. Therefore, the prospects for its use in the agro-industrial complex are quite high. At the same time, the process of developing such materials should be improved and promoted. Aluminum alloys are widely used in the aviation industry, in mechanical engineering and in agricultural production, due to their properties and light metal consumption. Alloys are resistant to water, they are not afraid of corrosion, sunlight, easily disinfected. All these properties are best suited for the use of aluminum in the storage of both cereals and livestock products. Moisture, dangerous molds, rodents and various insects are released and absorbed in storage. Aluminum has a high thermal conductivity and reflectivity, which reduce the risk of moisture condensation, which normalizes storage. The smoothness of this material suggests that the walls of aluminum structures collect much less dust. The proposed isothermal method of hot deformation of aluminum alloys in the processing of metals by pressure, differs from traditional deformation, and the temperature of the heated workpiece and the deforming tool is kept constant, close to the upper limit of forging temperatures, throughout the process. The deformation of the metal under isometric conditions and approximate deformations is characterized by an increase in ductility compared with ductility when machined in a cold tool. This is due to the lower rate of deformation, the lower limit of which is limited only by the productivity of the process. As a result, the "filling time" of defects that occur during metal deformation increases, the temperature stress in the workpiece volume decreases, the deformation becomes more uniform.

AbstractThe aim of this study was to evaluate the impact of the COVID-19 lockdown on agricultural production, livelihoods, food security, and dietary diversity in India. Phone interview surveys were conducted by trained enumerators across 12 states and 200 districts in India from 3 to 15 May 2020. A total of 1437 farmers completed the survey (94% male; 28% 30–39 years old; 38% with secondary schooling). About one in ten farmers (11%) did not harvest in the past month with primary reasons cited being unfavorable weather (37%) and lockdown-related reasons (24%). A total of 63% of farmers harvested in the past month (primarily wheat and vegetables), but only 44% had sold their crop; 12% were still trying to sell their crop, and 39% had stored their crop, with more than half (55%) reporting lockdown-related issues as the reason for storing. Seventy-nine percent of households with wage-workers witnessed a decline in wages in the past month and 49% of households with incomes from livestock witnessed a decline. Landless farmers were about 10 times more likely to skip a meal as compared to large farmers (18% versus 2%), but a majority reported receiving extra food rations from the government. Nearly all farmers reported consuming staple grains daily in the past week (97%), 63% consumed dairy daily, 40% vegetables daily, 26% pulses daily, and 7% fruit daily. These values are much lower than reported previously for farmers in India around this time of year before COVID-19: 94–95% dairy daily, 57–58% pulses daily, 64–65% vegetables daily, and 42–43% fruit daily. In conclusion, we found that the COVID-19 lockdown in India has primarily impacted farmers’ ability to sell their crops and livestock products and decreased daily wages and dietary diversity.

Aim. The presented study aims to substantiate a structural model for developing a sustainable development strategy in agricultural production, making allowance for changes in the level of impact of environmental factors.Tasks. The authors determine the reasons why the Russian agro-industrial complex (AIC) is lagging; identify the specific aspects of forming a strategy for the sustainable development of regional AICs; formulate urgent problems of sustainable development for the agri-food sector of the Russian economy at the federal, regional, and enterprise levels.Methods. This study uses a reasonable and objective approach to the problem of applying strategic management as a foundation for the sustainable development of agricultural production based on the knowledge of the laws of development of socio-ecological and economic systems and a study of multidirectional factors of the external and internal environment. The methodological basis for the sustainable development of agricultural production includes the concept of sustainable development as a priority at the macroeconomic level; strategy as a planning tool based on consistency with programs implemented at the federal, regional and municipal levels of public administration; methods and tools of strategic management at AIC enterprises.Results. The key aspects of the institutional-synergetic approach to the sustainable development of the AIC include the need to coordinate all factors by forming coherent goals not only among economic and financial institutions, but also for technopolises that combine scientific, industrial, financial, and entrepreneurial capital into one system cluster structure. The authors formulate the stages of implementing a strategy for the sustainable development of regional AICs, making it possible to come up with measures aimed at reorganizing the structure of the agricultural sector and to overcome the negative manifestations of crises in the Russian economy, thus minimizing their consequences.Conclusions. During the development of a strategy for the sustainable development of regional AICs, a multiplicative effect arises, making it possible to activate innovation policy and boost the development of other sectors of the economy, improving the population’s quality of life. When developing a strategy at the microeconomic level, it is necessary to make allowance for the specifics of the industry and the mission of a modern agro-industrial enterprise and to focus on solving problems formulated based on the trinity of goals of social, environmental, and economic long-term sustainable development.

Agriculture is the most important area of economic activity for the production of products and services in order to provide the population with quality food, industry with raw materials and promote sustainable development of rural areas. In recent years, there has been a downward trend in the rate of agricultural development, which is lagging behind the growth rate of the Russian economy as a whole. Structural changes in the agro-industrial complex have not produced significant positive results, which is caused by a number of reasons. One of the directions of agricultural policy in Russia is the accelerated development of animal husbandry and increasing the competitiveness of domestic livestock products in the domestic market. The state program for the development of agriculture and regulation of markets for agricultural products, raw materials and food provides for a set of measures for the priority development of animal husbandry. Implementation of these measures requires improved management in order to increase the efficiency of livestock production. The article considers aspects of the formation of accounting and analytical support for management of the livestock industry, economic and statistical analysis of trends and structural changes in the livestock industry. The best practices of Russian scientists in the field of accounting and agricultural Economics are summarized

Relevance. The effective use of agricultural land is a fundamental prerequisite for the successful implementation in the agro-industrial complex of the task of providing the population with food, and production with raw materials. At the same time, the issues of methodological support of the procedures for determining the integral indicator for assessing the use of agricultural land, established on the basis of a theoretically grounded unified approach based on quantitative methods, have been developed with insufficient completeness. Actualization of the issues of improving the theory and practice of assessing the effectiveness of the use of agricultural land in agricultural production is becoming one of the priority tasks of land reclamation science. The purpose of this work is to create a methodological basis for the process of assessing the use of agricultural land, which guarantees the comparability of the considered options for agroproduction in different natural and economic conditions.Methods. The research is based on the method of point assessments for indicators of agricultural land exploitation and the formation on their basis an integral criterion of land use efficiency. The proposed procedure includes: analysis of statistical data characterizing the dynamics of the values of indicators of used land resources, calculation of local assessments of the feasibility of their exploitation and assessment of the efficiency of land use according to a generalizing criterion represented by the sum of these local assessments.Results. A methodology has been developed and a method has been created for determining the efficiency of the use of agricultural land, based on a generalized integral assessment of the operation of agricultural land, which allows to identify bottlenecks in agricultural production and outline rational directions for the development of land use. The testing of the algorithm of the methodology and capabilities of the scale for the integral assessment of the efficiency of the use of land resources was carried out on the example of the Non-Black Earth Zone of the Russian Federation. Shown is an unsatisfactory (below the national average) contribution of agricultural production to the gross regional product. On the whole, positive dynamics of agricultural production in the Non-Black Earth Zone was established, which is achieved due to the development of animal husbandry, which is an effective factor in the formation of modern efficient agriculture of the territory, with the orientation of the crop production system on the raw material basis of feed production or the sector of the economy of the agro-industrial complex of the territory.

The purpose of the article is to highlight the conceptual understanding of the cluster as an innovative organizational and economic form of production in the system of sustainable development on the example of the agricultural sector and substantiate the scientific basis for ensuring its implementation at the regional level. Research methods. When carrying out the research, a set of general scientific methods and techniques was used; monographic - in the study of domestic and foreign publications and the above-mentioned problems; a systematic approach based on the principles of systems analysis and synthesis - to substantiate the relationship between sustainable development, the efficiency of agricultural production and the cluster model; abstract-logical - for the theoretical generalization of research results and determination of measures to ensure the implementation of the cluster model of agricultural development; economic analysis - to study the efficiency of agricultural production. Research results. The essence of the cluster in modern economic theory in the context of the concept of sustainable development has been studied and analyzed. Globalization, climate change and the aggravation of socio-economic and environmental problems in many countries of the world necessitate the search for new models of economic development. It has been established that one of the most optimal organizational and economic forms of effective agricultural production in the system of sustainable development is clusters. On the example of the Kirovograd region, a scientifically grounded regional model of the development of agro-clusters in the agro-industrial complex. Scientific novelty. Based on the synthesis of scientific theories of cluster and sustainable development, further study of theoretical and methodological approaches to the definition of the essence of clusters as a promising organizational and economic form of effective agricultural production in the system of sustainable development was obtained. Practical significance. The research results will find practical use in substantiating regional strategies for the development of agro-industrial production. They can be used in educational and educational programs, when providing consulting services for the creation of projects of agricultural clusters and in further scientific research.

Issues related to state support of the agro-industrial complex are relevant for all countries of the world, including the Russian Federation. The article deals with the key problems of the agro-industrial complex, which are mainly caused by the features of agriculture. The necessity of state support for the agro-industrial complex of Russia on the basis of the identified problems is substantiated. The article analyzes the directions and measures of state support in Russia, the differences between the stated goals in the state program for the development of the agro-industrial complex and the results in practice. The lack of a comprehensive approach to solving existing problems and proper control over the implementation of the state program, ill-considered and insufficient funding of individual programs, lobbying by large agricultural holdings of their interests and the monopolization of agricultural production do not allow to rely on the development of small agribusiness and rural areas.
