Abstract
Agro-food systems require nutrient input from several sources to provide food products and food-related services. Many of the nutrients are lost to the environment during supply chains, potentially threatening human and ecosystem health. Countries therefore need to reduce their nutrient/nitrogen footprints. These footprints are importantly affected by links between sectors. However, existing assessments omit the links between sectors, especially between the agriculture, manufacturing, and energy sectors. We propose a novel approach called the nutrient-extended input–output (NutrIO) method to determine the nutrient footprint as a sum of direct and indirect inputs throughout the supply chains from different sources of nutrients. The NutrIO method is based on a nutrient-based material flow analysis linked to economic transactions. Applying this method, we estimated the nitrogen footprint of Japan in 2011 at 21.8 kg-N capita−1yr−1: 9.7 kg-N capita−1 yr−1 sourced from new nitrogen for agriculture and fisheries, 7.0 kg-N capita−1 yr−1 from recycled nitrogen as organic fertilizers, and 5.1 kg-N capita−1 yr−1 from industrial nitrogen for chemical industries other than fertilizers. A further annexed 55.4 kg-N capita−1 yr−1 of unintended nitrogen input was sourced from fossil fuels for energy production. The nitrogen intensity of the wheat and barley cultivation sector, at 1.50 kg-N per thousand Japanese yen (JPY) production, was much higher than that of the 0.12 kg-N per thousand JPY production for the rice cultivation sector. Industrial nitrogen accounted for 2%–7% of the nitrogen footprint of each major food-related sector. The NutrIO nitrogen footprint sourced from new nitrogen for agriculture and fisheries, at 8.6 kg-N capita−1 yr−1 for domestic final products, is comparable to the food nitrogen footprint calculated by other methods, at 8.5–10.5 kg-N capita−1 yr−1. The NutrIO method provides quantitative insights for all stakeholders of food consumption and production to improve the nutrient use efficiencies of agro-food supply chains.
On the issue of forming a unified system of assessment and logistics schemes for the management of solid municipal waste, depending on the type of urban agglomeration development
Authors: Akanov A V , Belov V V 
Published: October 2021

Abstract
At the moment all over the world there is an acute problem of solid municipal waste (MSW) management. A significant number of studies in recent years devoted to this topic are reduced to predicting the volume of waste generated in urban agglomerations with the subsequent construction of logistics schemes. However, the authors of these studies consider the total amount of waste generated per capita within the municipalities with the subsequent extrapolation of the obtained analytical or statistical data in order to make predictive estimates, for which, in these studies, the corresponding mathematical relationships are given. The study of the influence of the development processes of the territory, together with the assessment of the formation of MSW from various groups of objects within the urban agglomeration and the subsequent planning of the development of this agglomeration, as well as the model for the formation of logistic schemes, are not fully presented. The dependencies proposed for the assessment by various researchers are not always adaptive, since in most cases, the authors of the studies are not interested in the criteria affecting waste generation, but in the very fact of the possibility of predicting the construction of logistics schemes for waste management. Therefore, this paper analyzes the volume of MSW education in educational institutions, using the example of the city of Moscow (Russian Federation) in various construction options. The authors take into account: the degree of population of the study area, and integrally, in the volume of MSW formation - the processes of internal interdistrict migration; food system built in an educational institution, waste generated by the staff of these institutions. As a result, the authors concluded that already at the planning stage of the development of an urban agglomeration, from the standpoint of waste generation from accompanying social facilities, preference should be given to more concise construction schemes (for example, “infill” construction), while for uniform loading of processing (recycling) facilities should be allocated to the modes of operation of preschool educational institutions and schools in time.

Abstract
The purpose of business activity is to satisfy customers’ and partners’ demands, make profit and ensure the well-being of society. The analysis of dairy industry and population needs is of great importance to commodity experts’ opinion. The objects of the study were world, national and regional (Irkutsk region) needs of the population for dairy products during 2018-2020. Empirical and sociological methods were used to analyze primary and secondary marketing information. There is a negative tendency in dairy foods consumption since it is decreasing annually (the world market by 1.12 % annually, the Russian market by 2.39 % and Irkutsk regional market by 2 %). Dairy products take the first place in the Russian federal consumer basket and make 25.6 %. The recommended annual consumption is 256-361 kg/year, the consumption range for children and adults is 25-34%. Irkutsk regional consumption of dairy products is 17 % lower than the recommended rate. Dairy products are at the top of “healthy” consumer basket and account for 36 % of its volume. The dairy market is moving towards functional food products which contribute to rational nutrition. The target consumers are people aged 15-36. The share of functional dairy products makes 68 % of the functional product market in Irkutsk region. People under the age of 35 tend to choose yoghurts and new types of sour milk drinks. Middle-aged and elderly people most often buy sour cream, cottage cheese and ryazhenka. Consumers over 45 have no interest in functional dairy products. 15 % of consumers tend to choose dairy foods with different flavor additives, 12 % are likely to choose dairy foods with minerals, 9 % prefer bifidus and lactic bacteria, 8 % of consumers choose other dairy foods, the rest of them are fond of classical products. The range of dairy products is increasing, the main emphasis is on fermented milk products. Special attention is being paid to the production of multifunctional foods produced according to the principles of naturalness and a higher biological value.

Abstract
The article presents sire proving results of 11 Holstein stud bulls of three lines of breeding, i.e. Vis Back Ideal 1013415, Reflection Sovering 198998, and Montvik Chieftain 95679. Experimental studies were conducted in the conditions of a dairy complex of OOO agricultural enterprise “Donskoe” in the Volgograd region. Comparative analysis of bulls’ daughters in the first complete lactation with their mothers and herdmates showed that the average milk yield of daughters of bulls under study varied within 8256-9895 kg, the fat content values of milk were 3.80-4.30%, and the protein content values ranged from 3.10 to 3.40%. Seven of the sire proved bulls were recognized as improving bulls with varying degrees of genetic potential realized. The Vis Back Ideal 1013415 bulls’ daughters were found to have superior milk yield in comparison with the Reflection Sovering 198998 and Montvik Chieftain 95679 bulls’ daughters. Moreover, the Reflection Sovering bulls’ daughters outnumbered the Vis Back Ideal bulls’ daughters in terms of the fat content in milk by an average of 0.1%. The milk yields of all evaluated bulls’ daughters exceeded their mothers with respect to the milk yield, which indicated genetic progress over a generation. Thus, the stud bulls that turned out to be improving in terms of the milk yield and fat content will further improve the productive traits of cows.

Abstract
The paper analyzes the modern water management balance of the Republic of Crimea in the context of administrative and territorial units. The possibility of using the ArcGIS 10.4 software package for visualization of spatial statistical data that characterize the water balance is shown. The forecast values of the water balance of the Republic of Crimea for 2030 are given. Maps of the current water management balance for the administrative-territorial units of the Republic of Crimea for the current period and for 2030 based on statistical observations have been constructed. It has been established that the territory of the Republic of Crimea is extremely water-deficient and only in certain administrative-territorial units a positive water balance is observed (Bakhchisarai and Belogorsk regions of the Republic of Crimea, Sudak urban district, Alushta urban district and Yalta urban district). At the same time, according to forecasts, by 2030 it will be possible to significantly reduce the water deficit, but a number of regions of the Republic of Crimea will still have a negative water balance.

Published: October 2021

Abstract
Nowadays, in the agricultural industry, area monitoring is carried out using drones that are not linked to other devices such as ground-based automatic harvesters or drip irrigation systems. This results in a lot of time-consuming decision-making for harvesting ripe different crops or for pesticide treatment of areas of crops that need it immediately. This problem can be solved by using a monitoring system with heterogeneous robotic means, which allows the distribution of tasks between aerial robotic means. The purpose of this work is to optimize the algorithm of the control system for a group of robotic assets using a multigeneric decision-making approach. Many methods of operator decision support, control algorithms for solving the task of agricultural monitoring, used by scientific teams in the development of heterogeneous robotic means do not solve the problem in full. The approach is based on model optimization, namely the theory of auctions within the developed system, allowing to find a robotic system providing the maximum probability of fulfillment of the set task.

Published: October 2021

Abstract
The results of the development of predictive models of the yield of spring wheat based on the use of the decision tree method are presented. When constructing the models, qualitative factors were taken into account (the level of intensification, the system of soil cultivation, the placement of the crop after steam) and agrometeorological resources (the sum of active air temperatures, precipitation). The minimum number of input parameters (public data) was used for the generality of the system and its versatility for different natural and agricultural conditions. The efficiency of using decision trees for forecasting wheat yield is shown. The accuracy of the constructed models was evaluated on the training and test samples and the following indicators were achieved (CART method): average absolute error - 3.455 (training sample) and 4.446 (test sample); determination coefficient - 0.895 (training sample) and 0.811 (test sample). A set of rules has been obtained that determine the level of crop yield depending on the complex of control actions and the prevailing conditions.
