Published: July 2021

This study was conducted to determine the level of acceptance among the Bangsamoro mujahidin on the proposed Bangsamoro federal state. Convenient and quota sampling were used among the 120 respondents identified for this study. It is found that most of the participants accepted the proposed federalism of the current government, though having some conditions. The regression analysis result showed that age was negatively correlated with their level of acceptance on the proposed federal state while educational attainment on both secular and Islamic schools was positively correlated with their response to the same provision statement. This study concluded that Bangsamoro mujahidin are now more welcoming to various alternative solutions to the Mindanao conflict within the framework of Philippine territorial integrity.

Liukang Tuppabiring is a waters with marine biodiversity potential large enough to be developed and managed sustainably. Utilization around the coral reefs in the waters of the Liukang Tuppabiring sub-district currently tends to lead to destructive use, so it is necessary to take damage prevention measures immediately. The results showed the condition of coral cover in the medium and damaged, while at stations 1,2,3,4,6 (25,47-41.07%), while conditions were good at station 5 (56.20%). The number of individual reef fish is 290 individuals from 46 species of 22 genera 11 families. At the research location also identified one type of protected biota namely Hawksbill (Eretmochelys imbricata). Coral damage that occurred at 6 observation stations was more caused by the practice of using destructive and environmentally unfriendly fishing equipment such as bombs, trawls, and the use of poisons. The priority strategies undertaken in the management of coral reefs at the study site are 1) Management of environmentally friendly coral reefs where the community as a manager with strong support from the Government; 2) Making clear rules related to utilization in coral reef areas and establishing a POSMAKWAS institution to avoid more severe coral damage; 3) Improve supervision and law enforcement must be firm in relation to the use of fishing gear that can damage coral reef ecosystems.
Vying voices of the pandemic
Authors: Adewole Caroline
Published: July 2021

This article documents and explores the painful impact of a gruesome racial attack during the first lockdown in the wake of the Covid-19 pandemic. It occurred less than a fortnight before the brutal murder of George Floyd in America.
It is a reflection on the issue of racism and the marginalisation of less dominant groups in and outside the borders of Great Britain.
It is the recognition and exploration in myself of an internalised colony of voices emerging as a response to the traumatic event. Tracking the intra-psychic and interpersonal dynamics involved in the racism and the subsequent attempt at an anti-racist answer leads to self-reflection on my part and the confrontation of my own bias. Eventually, I can feel my underlying vulnerability and the resulting shift. The sense of self-awareness and agency evolves into the mobilisation of an extensive mentalizing process.
The article attempts to capture the subtle, insidious nature of othering and the fear behind the defences we use to keep this in place; the centrality of our capacity to courageously embrace our vulnerability as crucial to our ability to embrace and treat with dignity people who are different from us. The article touches on hopefulness that one day this socially constructed monster, racism, would be a thing of the past, not just on paper but in the human psyche also.

Survival of the survivors; containment for the uncontained
Authors: Rossi Rebecca Silvia
Published: July 2021

Video therapy can be a great help when seeing patients face to face is not possible, as has widely occurred due to the Covid-19 lockdown. We must unpack and fully understand video therapy as a type of practice, given that it is different from our standard mode of therapy. Through a specific clinical case, I will highlight a paradox of this type of therapy: namely, that the screen can act as an aid for the patient but an obstacle for the therapist. Specifically, its mediation can support emotionally coerced patients to express and contact their emotions better, whilst this same screen can act as an obstacle for the therapist who may struggle to contain the patient emotionally. The clinical case I will discuss is about Judy, a patient who suffered relational trauma from early childhood, with whom I struggled to contain emotionally in her first real connection with her feelings, which occurred through video therapy.
Did the Nazi Holocaust cause schizophrenia?
Authors: Kahr Brett
Published: July 2021

After centuries of controversy, mental health professionals still cannot agree on the cause or causes of schizophrenia — the most severe form of psychosis. Theories of aetiology range from genetic, biochemical, and neuropathological approaches to those of an environmental or intrafamilial nature. In this contribution, the author considers the impact of massive psychological traumatisation, examining, in particular, the relatively neglected literature on the role of the Nazi Holocaust in the development of psychotic states. Reviewing the work of such pioneering clinicians as Bruno Bettelheim and William Niederland, each of whom observed acute schizophrenic reactions among survivor patients, the author then surveys the more methodologically sophisticated work of Udo Reulbach and his colleagues who have provided strong evidence that those survivors of concentration camps who endured the most objectively traumatising of experiences, including the death of both parents, would be far more likely, statistically, to receive a diagnosis of schizophrenia in later life. The author argues that the literature on the Holocaust provides important data for an understanding of the role of disrupted attachments and extreme traumatisation in the development of schizophrenic psychoses.

Working with adolescents virtually during the Covid-19 period
Authors: Duarte Isabel
Published: July 2021

In this article, the author proposes to present her therapeutic work with adolescents during the Covid-19 period carried out remotely using Skype. Based on the theories that allow us to understand adolescence as a process of growth and transformation, it was possible to acknowledge the changes that took place in three adolescents in different stages of a relational therapy. The imposition of working virtually created a new way of practising psychotherapy, where the notions of transference and countertransference were essential for the understanding of the intra- and inter-psychic processes that take place in the internal world. Skype was the tool that made it possible to continue the relational presence for working with adolescents.
Extending the Tavistock model: bringing desire, danger, dread, and excitement into a theory of organisational process
Authors: Hirschhorn Larry
Published: July 2021

This article develops some novel extensions of the classical Tavistock model of organisational psychodynamics. The classical model privileges the emotion of anxiety as the primary trigger for psychosocial experiences in organisations. While this approach has been very generative, it has also been limiting, since there are several other important emotions that shape how people take up their work and their roles in organisations. The article shows how open systems theory and sociotechnical thinking emerge logically from the anxiety model by highlighting how organisations become functional, and work becomes satisfying. The article goes on to explore how desire as a feeling for the future, stimulates such feelings as danger, dread, and excitement. When these feelings become dispositive, they generate experiences associated with anxiety, and the primary risk, as well as the potential for developmental politics. Politics can be developmental rather than defensive when executives create settings where conflict is seen as transaction and rationality as an achievement. This article explores these issues through the use of case vignettes in the public domain, including a skunk works project in Data General, and leadership struggles and strategy dilemmas in Apple, IBM, and Polaroid.
Executive group coaching: interventions not for the faint of heart
Authors: Kets de Vries Manfred F. R. , Rook Caroline
Published: July 2021

As the world is changing, organisations are changing with it: matrix structures, flat hierarchies, virtual work, and teamwork are becoming the norm. Therefore, the ability of working successfully with others has become increasingly important and effective teamwork is essential to make these new complex organisational structures work. However, as this special issue highlights, there are major challenges in working effectively together in this rapidly changing world. Indeed, teams often do not live up to the promise of faster problem solving or higher levels of innovation. "Turf wars" and broken trust are common. Group coaching interventions can be second to none in creating effective collaboration and a culture of trust. Based on the clinical paradigm, this article outlines competencies and conceptual models that make for successful group coaching. Overall, effective group coaching interventions, which will also help executives to lead and direct individual and organisational transformation and to create a coaching culture within organisations, need group coaches who have a holistic orientation and pay attention both to micro and macro processes.
Emotional textual analysis as a semiotic action–research method to work with emotions within organisations
Authors: Bisogni Felice , Dolcetti Francesca , Pirrotta Stefano
Published: July 2021

This article aims to contribute to the special issue for the twentieth anniversary of the Organisational and Social Dynamics journal presenting a semiotic action–research method called emotional textual analysis (ETA). ETA, developed in Italy by the Studio of Psychosociology and the Chair of Clinical Psychology at Sapienza University of Rome, is an explorative abductive method that consents to analyse how the organisation symbolically interacts with its context. In ETA methodology the interdependence between the organisational system and the client system is considered as the product of socially shared emotional cultures. This article describes the theoretical and methodological foundation of the ETA method and presents the results of a recent action–research project carried out by the authors within a National Health System organisation. In the conclusion, the added value of using ETA to work with organisations facing contextual changes in the current historical period is discussed.
From here to eternity? Work, coaching, and consulting in a post-Covid world
Authors: Brunning Halina , Khaleelee Olya
Published: July 2021

This article, written for the special twentieth anniversary edition of Organisational and Social Dynamics, examines how the technological revolution and the pandemic are changing the shape of organisations and the future requirements from advisory services such as coaching and consulting, within the context of a PC culture and anxiety about climate change. The authors describe how AI and robotics are influencing the nature of work, replacing many jobs and enabling managers to be less operational and more strategic in orientation. The influence of the Black Lives Matter movement and the introduction of Universal Basic Income are described. The effect of the pandemic on the human psyche, on employment, poverty, homelessness, racism, and mental illness are spelt out as well as the implications for the world of work and organisational life. Attention is paid to the impact on the role of coach/coachee, using the six-domain model of coaching with predictions of how coaching may change in the future. The final section is devoted to organisational consulting and how the impact of the pandemic may transform client/consulting relationships.
Group relations conferences in China 2014 to 2019: theory and dynamics
Authors: Harkins Seth , Lu Xiaohua
Published: July 2021

This is a longitudinal inquiry into the theory and dynamics of four group relations conferences in China from 2014 to 2019. The study triangulates field notes, document artefacts, and verbatim transcribed interviews to investigate the application of Wilfred Bion's basic assumption (BA) group theory in the context of temporary learning institutions devoted to the examination of authority, leadership, and conscious/unconscious processes in groups. Given that group relations theory and practice in the Tavistock tradition is grounded in psychoanalysis and open systems theory, the study integrates psychoanalytic and psychodynamic systems theory in the analysis and interpretation of conference dynamics. The study concludes that group relations has important implications for psychoanalysis in China in light of: 1) the "psycho boom" in contemporary China; 2) the possibilities of cross-cultural learning and knowledge transfer; 3) cross-cultural trust building; 4) professional development of human services, mental health, and organisational development professionals; and 5) the application of psychoanalytical theory and practices to the understanding of organisational development in China.
A Chinese family: teaching and learning in a clinical case conference
Authors: Zhenlei Luo , Scharff Jill Savege
Published: July 2021

The authors show the interrelated processes of teaching and learning both for the Chinese student and the Western teacher. This article focuses on a clinical case conference as a co-constructed teaching and learning opportunity for Chinese therapists and Western teachers of family therapy. We present an account of a clinical case conference for family therapy students which occurred as part of a week-long training event, during the two-year continuous training programme in psychoanalytic couple and family therapy organised by Professor Fang Xin in Beijing. The first author, a Chinese family therapy student, made the family case presentation to her classmates and to the second author, a Western psychoanalyst as the discussant. The student introduced the referral to her of an index patient, a teenage boy who was refusing school, staying home to play videogames, and threatening suicide. She reported vividly on her consultation with the concerned mother, stern father, and rebellious adolescent son in a family group setting. Without process notes, the Western discussant could not comment on the presenter's analytic family therapy technique or move more deeply into the family unconscious. Yet, the material presented enabled the class to see how the boy had become the symptom bearer for his family, and at the same to learn about the strain of absence and the threat of death on a Chinese family. The article closes with a template for how to get the most out of a clinical case conference.

China's great transformation: from duty to personal rejuvenation and well-being
Authors: Jankowiak William
Published: July 2021

If the freedom to choose is important for personal well-being, what happens when there are drastic restrictions on personal choice? China represents an opportune case to explore this question. Its fifty-plus years of experimenting with a redistributive command economy, combined with periodic bursts of political fever, made extreme egalitarianism more important than other Chinese values recognising individual merit, vision, and achievement. Throughout much of Chinese history, these values were widely shared; but in the current era, an alternative cultural model was stressed: social responsibility for the community and nation. Individuals were ideally expected to de-emphasise their individuality in favour of "the common good". In China, the juxtaposition of the two competing value systems—extreme egalitarianism versus individual choice, responsibility, and personal achievement—engendered confusion, anger, angst, and unhappiness. In China, from 1949 to 1976, this accounts, in part, for much of the suffering people experienced in living their lives.
In this article I examine the Chinese cultural model for life satisfaction or wellbeing in two different eras: work unit (danwei), socialism (1981–1983), and market reform (1987–2000). My sample was found in Hohhot, the provincial capital of the Inner Mongolia Autonomous Region in northern China, where I lived from 1981 to 1983; six months in 1987; five months in 2000 (a total of 35 months). I will also examine the ways Chinese sought well-being in four different domains: friendship, family, occupation, and fun activities. By analysing how Chinese conceptualised their lives over time, I will identify the conceptual frameworks individuals used to assess their relative well-being.
Segmenting Investors on their Biases Manifested in Investment Decision-Making by Individual Investors
Authors: Fatima Afreen , Sharma Jitendra Kumar
Published: July 2021

Purpose- This study proposes to identify the certain biases affecting investor decision-making and to segment investors accordingly.
Design/Methodology- A quantitative research method was applied to measure the existence and impact of the biases on investment decision-making. A survey was administered among the stock market investors in Uttar Pradesh. Factor analysis was used to extract those biases that significantly impact investment decision-making and their mean score to assess the level of agreement that affects their investment decisions.
Findings - The finding reveals that eight extracted factors affect the investment decisions and accordingly segment them on the biases they exhibit. The investors tend to fall into Imitator, Stereotypical, Independent Individualist, Risk Intolerant, Efficient Planner, Confident, Passive, and Competent Confirmer. The Imitators, Independent Individualists, and Confident investors show their higher level of agreement that highly affects their equity investment decision-making.
Practical Implication- This study provides a base to segment the investors on their biases. In addition, it will help in customizing the investment recommendation based on their biases to improve the investment decisions.
Radiation therapy‐associated toxicity: Etiology, management, and prevention
Authors: Wang Kyle , Tepper Joel E.
Published: July 2021

Radiation therapy (RT) is a curative treatment for many malignancies and provides effective palliation in patients with tumor‐related symptoms. However, the biophysical effects of RT are not specific to tumor cells and may produce toxicity due to exposure of surrounding organs and tissues. In this article, the authors review the clinical context, pathophysiology, risk factors, presentation, and management of RT side effects in each human organ system. Ionizing radiation works by producing DNA damage leading to tumor death, but effects on normal tissue may result in acute and/or late toxicity. The manifestation of toxicity depends on both cellular characteristics and affected organs' anatomy and physiology. There is usually a direct relationship between the radiation dose and volume to normal tissues and the risk of toxicity, which has led to guidelines and recommended dose limits for most tissues. Side effects are multifactorial, with contributions from baseline patient characteristics and other oncologic treatments. Technological advances in recent decades have decreased RT toxicity by dramatically improving the ability to deliver RT that maximizes tumor dose and minimizes organ dose. Thus the study of RT‐associated toxicity is a complex, core component of radiation oncology training that continues to evolve alongside advances in cancer management. Because RT is used in up to one‐half of all patients with cancer, an understanding of its acute and late effects in different organ systems is clinically pertinent to both oncologists and nononcologists.

Inheritance of resistance of spring barley to Erysiphe graminis f. sp. hordei in F1 and variability in F2 in the conditions of the Right-Bank Forest-Steppe of Ukraine
Authors: Sabadyn V. , Sydorova I. , Kumanska Yu. , Burlachenko D.
Published: July 2021

The nature of the inheritance of resistance to Erysiphe graminis f. sp. hordei in the crosses of genotypes of spring barley in F1 and transgressive variability in F2 populations are investigated. Inheritance of the trait of resistance to Erysiphe graminis f. sp. hordei in F1, by hybridization of genotypes of spring barley with known genes of resistance to Erysiphe graminis f. sp. hordei in European varieties Eunova (mlo11) and Barke (mlo9), which are located on chromosome 1H, was positively dominated. Inheritance of the F1 trait in Aspen (mlo11) and Adonis (mlo9) cultivars was partially positive. The inﬂuence of parental pairs for hybridization on the indicators of the degree of phenotypic dominance, hypothetical and true heterosis was established. Resistance to Erysiphe graminis f. sp. hordei in F1 hybrids was observed heterosis (positive dominance) in fve hybrid combinations (hp = 1.1–1.9 %): Barke/Badoryi, Barke/Sanktrum, Parnas/Rostentsii, Badoryi/ Barke, Eunova/Zvershennia. Hypothetical heterosis (Ht) in F1 was observed in 13 of 16 hybrids (from +2.8 % to +97.6 %). A positive value of true heterosis (Htb) in F1 was observed in 15 hybrids out of 16 (from +1.9 % to +98.8 %). Inheritance of the trait of resistance to Erysiphe graminis f. sp. hordei in all studied hybrids was inﬂuenced by the cytoplasm of the mother plant, except for the hybrid Eunova / Triangel, where the inﬂuence of the nuclear apparatus was detected. Hybrids were found in the F 2 population with high resistance to Erysiphe graminis f. sp. hordei, which exceeded the parental components, which indicates a signifcant shaping process and the possibility of selection on the basis of the studied trait. The degree of positive transgression ranged from 16.0 % to 73.0 % in hybrids Aspen / Skarlet, Adonis / Vanja, Barke / Badoryi, Barke / Sanktrum, Eunova / Triangel and Eunova / Zvershennia, where highly resistant varieties were used for the mother form. The combinations in which the frequency of transgression was observed in more than 50.0 % of plants are hybrids: Eunova / Triangel, Barke / Sanktrum, Eunova / Zvershennia, Parnas / Rostentsii and Barke / Badoryi.
Key words: spring barley, resistance, Erysiphe graminis f. sp. hordei, combinations of crossing, inheritance, F1, true and hypothetical heterosis, degree of phenotypic dominance, F 2, degree and frequency of transgressions.
Investigations of radiation exposures in the aftermath of the Chernobyl accident
Authors: Michel R. , Romanchuk L.
Published: July 2021

Long-term assessment of the aftermath of the Chernobyl and Fukushima accidents deals with the study of radionuclide emissions and radiation exposure in heavily polluted regions. A signifcant diﬀerence in the composition and nature of radionuclide emissions during accidents at nuclear power plants is considered in the study - a largescale radioactive fallout transfer and precipitation over the USSR and Europe took place in Chernobyl due to the uncovered core of the reactor while at Fukushima a massive emission of inert gases occurred. It is noted that based on the density of precipitation, the data indicating that the vital doses of 137Cs remain signifcantly lower or within the range of natural radiation exposure were obtained. However, due to a short half-life (8.0 days) of 131I, there are no available comprehensive measurements of 131I exposure after the accident. It is noted that retrospective dosimetry of the effect of 131I on the thyroid gland through 129I with a half-life of 15.7 Ma allows to fll the gap in this issue. 137Cs precipitation was analyzed by gamma spectrometry, 129I was studied by accelerating mass spectrometry in soil samples from 60 places in zones II and III in the north of Ukraine and the thyroid gland radiation dose in the population. Critical comparing of the results obtained with those of rare direct measurements of 131I activity in the human thyroid gland reveal that the doses are at the lower limit. The actual radiation exposure in the contaminated regions of Northern Ukraine was considered by estimating the exposure dose in returnees in the village of Khrystynivka where 30 families live and consume locally produced products in the evacuated zone II, 75 km from the Chernobyl NPP. The results show that the additional irradiation with 137Cs the returnees received was low. The possibility of safe living in heavily polluted areas is noted. Under the normal way of life, the total radiation exposure of Khrystynivka village residents was within the natural radiation exposure range.
Key words: radioactive fallout, radiation exposure, radiation pollution, irradiation of returnees.
Heat stress in dairy cows

This review includes an analysis of the literature on various influencing factors influencing heat stress in lactating dairy cows and the way it affects milk production. Signs and symptoms of heat stress in cows are reduced feed consumption and decreased milk yield, elevated breathing rate, increased body temperature and reduced reproductive overall performance. There are other problems for example, a seasonal growth in bulk tank somatic cell counts. The birth weight is decreased in cows which have been exposed to heat stress throughout the dry length. It is established that the most critical is the heat accumulated via direct radiation from the solar. It was found out that high feed consumption results in raised metabolic heat increment. High metabolic warmness increment requires powerful thermoregulatory mechanisms to maintain body temperature in a thermoneutral area and in physiological homeostasis. It is confirmed that heat stress is complicated because the responses to heat stress have an effect on not best the energy stability, but also water, sodium, potassium and chlorine metabolism. Plasma progesterone degrees may be elevated or reduced depending on whether or not the heat pressure is acute or chronic. Water, sodium, potassium and chlorine are vital constituents of sweat, and sweating is a chief, if not the most important, thermoregulatory mechanism used to burn up extra body heat. Strategies to reduce heat stress must be evolved to enable cows to express their full genetic ability.
Key words: dairy cows, heat stress, thermoregulatory mechanism, water, feed consumption, mineral elements.

Background: Tension-type headache is a common neurological problem among general population of Bangladesh.

Objective: This study was undertaken to ascertain the frequency of subclinical and over hypothyroidism in patients with infrequent TTH.

Methodology: This study was conducted in a tertiary care hospital Dhaka medical college in Bangladesh. The study subjects consisted of 200 patients primary headache disorders. Thyroid function test were performed. All four sub-types of tension type headache were considered to include in the study, namely: Infrequent episodic (or infrequent), frequent episodic (or frequent), chronic sub-type and probable sub-type.

Result: Forty percent (40%) patients in this study had infrequent TTH, 30% had frequent episodic TTH, 21% had chronic sub-type of TTH and 9% patients had probable sub-type of TTH. overt hypothyroidism. Among 46 patients with frequent episodic TTH 10 patients had subclinical hypothyroidism and 4 patients had overt hypothyroidism. Out of 18 patients with probable TTH 3 patients had subclinical hypothyroidism but no patient was overt hypothyroid. Out of 42 chronic TTH patients 12 had subclinical and another 12 had overt hypothyroidism. Statistically significant difference was seen among different sub-types of headache in relation to thyroid status.

Conclusion: Hypothyroidism is found to be a co morbidity or precipitating factors to be development of infrequent type of tension-type headache.

Modern Methods of Extracting Key Information From Regulatory Documents
Authors: Milkova Maria A. , Nevolin Ivan V. , Pigorev Dmitriy P.
Published: July 2021

This article is an attempt to comprehend the difficulties and propose approaches to eliminate them when analyzing legal documents in the framework of economic and interdisciplinary research. The utmost goal is to seek incorporating advances in computational linguistics and natural language analysis into the discourse of the digital economy in order to develop methods involved in decision-making and strategy development based on the analysis of textual information. In conditions when the amount of information is too large, is constantly updated and / or the area of study is new, the most expedient at the first stage is to obtain the general structure of the entire collection of documents, some kind of semantic compression of information. The practical part contains the development of an approach for the analysis of regulations governing food and nutrition issues, in particular, related to the prevention of the development of iron deficiency anemia (IDA). The approach includes the extraction of key information of voluminous texts (keywords and key sentences) based on the TextRank graph algorithm. An important link contributing to cognition is also the visualization of semantic relationships between words within documents. In our opinion, it is the combination of semantic compression and visualization of information as a “close-up” of text documents, as well as the possibility of further detailing by linear reading and analysis, which are the most relevant approach in conditions of information overload and attention deficit. The active introduction of text analytics methods for systems that are not involved in attention markets, which lag significantly behind in the convenience of extracting meaningful information, is especially important. Approaches to improve the understanding of large volumes of regulations will be of significant value to researchers in economic, legal or multidisciplinary research.
Valuation of Machines with a Random Service Life Based on the System of National Accounts – 2008
Authors: Smolyak Sergey A.
Published: July 2021

We propose a mathematical model describing the decrease in the market value of machines (depreciation) with age in a situation where its service life is random and has a Weibull distribution. We measure the depreciation of a used machinery item using a goodness factor, that is, the ratio of its value to the value of a similar new machinery item. The model is based on the principle of anticipation of benefits adopted in the valuation theory and the discounting cash flows method. The model takes into account that machine’s technical and economic characteristics deteriorate with age and its benefits are reduced according to the hyperbolic dependence adopted in the system of national accounts SNA‑2008. We have built the dependences of average machine's goodness factor on its relative age (the ratio of the actual age to the average service life). Calculations show that the discount rate and average service life have little effect on these dependencies. This made it possible to divide the machines into three categories and propose for each of them its own dependence of the goodness factor on the relative age, which is convenient for practical use in appraisal activities.

Published: July 2021

Improving the management of social and economic development is now a pressing issue. First of all, the strategic component attracts attention, the importance of which is particularly increased in connection with the objectives of the implementation of national projects, which should have a significant impact on the achievement of key social development goals. The institutional aspect is an important part of the process of improving strategic governance. This is because such basic strategic management elements as targeting and identifying problems, as well as developing (adoption) of a solution, are heavily influenced by institutional factors. The methodological grounds are formed by the important principles and categories of general system theory (ES) of: social and economic development (SDS), structuring of the socio-economic system (SES), targeting, analysis of problems in the development of SES, the system of management of these processes. This work is addressed to researchers specializing in strategy analysis, planning processes and management of social and economic development strategies.
Future of Food Safety and Possibility of Its Realization in Russia

Published: July 2021

The possibilities of minimizing the negative impact on food security of the likely changes in the external conditions of agricultural production, which are not eliminated by the efforts of enterprises, are discussed. Attention is drawn to the increasing decline in agriculturally suitable land, especially land with high rental potential – ​near cities and accessible transport routes. Negative for food security may be in foreign trade geopolitical changes, unfavorable for the economy as a whole, and for the consumer market. Known climatic anomalies, the danger of pandemics and epidemics are among the most adverse factors. As an effective direction of agricultural policy, the state considers possible options to help enterprises to acquire and develop high-performance new technologies in crop and livestock production, financing the expansion of sought-after agricultural land. These measures are considered in addition to the current practice of supporting low-profit farms.
