**2. Literature Review**

In order to fulfill the task of comprehensiveness of the research, it is necessary to generalize potential environmental determinants influencing a country's food security (alternatively, foodstuff production, agribusiness performance, etc.) that were previously mentioned by scientists. Basically, some theoretical and empirical findings confirm the hypothesis about social, economic, or environmental factors' impacts on countries' food security as a whole or its particular perspective.

It should be noted that there is a set of scientific research that, in general terms, supports the hypothesis about the influence of environmental factors on a country's food security or its proxies. Namely, Musová, Musa, and Ludhova [5], Dwikuncoro and Ratajczak [6], and Vasa [7] researched factors influencing food purchasing (food utilization) in the Slovak Republic, Poland, and Hungary. They found out that consumer behavior is mostly driven by economic factors (quality and prices of products, household income). However, environmental factors also matter—69% of respondents mentioned that they prefer environmentally friendly goods. Moreover, Jakubowska and Radzymi ´nska [8] found out that Czech students, who participated in the research, declare environmental motives as dominant in their consumer choices. Dabija, Bejan, and Dinu [9] also identified that consumers of Generation Z prefer green suppliers. In turn, Gadeikiene, Dovalien ˙ e, Grase, and Banyt ˙ e [ ˙ 10], Arslan [11], Olasiuk and Bhardwaj [12], and Ahmad [13] reveal that environmental preconditions and comprehensive nutrition knowledge play an important role in ensuring sustainable consumption. Thus, this group of scientists supports the idea that environmental image and responsibility are impactful for food consumption (food utilization proxy of a country's food security).

In terms of discussing the impact of environmental determinants on the performance of food producers and foodstuff trade, i.e., food availability and partial food access, Morkunas, Volkov, and ¯ Pazienza [14], Morkunas et al. [ ¯ 15], and Tomchuk et al. [16] mentioned that economic and environmental factors have an impact for resilience of agricultural enterprises. Similarly, Handayani, Wahyudi, and Suharnomo [17], Mikhaylova et al. [18], Akhtar [19], Kheyfets and Chernova [20], Stjepanovi´c, Tomi´c, and Škare [21], Cismas et al. [22], Jayasundera [23], and Harold [24] proved that green innovations positively influence business performance, sustainability of agriculture, and food security. Haninun, Lindrianasari, and Denziana [25] mentioned that environmental performance has an effect on financial performance. Ortikov, Smutka, and Benešován [26] reveal that increase of innovativeness and eco-friendliness might be among essential preconditions of an increase of competitiveness of Uzbekistan's agrarian foreign trade. However, Shuquan [27] empirically proved the existence of the relationship between international trade and countries' environmental performance (case of China). In turn, Smutka, Maitah, and Svatoš [28], Falkowski [29], and Kadochnikov and Fedyunina [30] pointed out that, in the case of Russian foodstuff imports, not environmental, but economic and political factors matter. However, in the case of Russia's exports to EU countries, political and environmental determinants play a more significant role. This block of research supports the idea that eco-friendliness and environmental responsibility are not just influencing consumers' motives, but also argue that agricultural enterprises are also driven by environmental motives. Nevertheless, these researches

also allow us to conclude that environmental factors play a prior role in foodstu ff trade in developed countries, but a secondary role in developing countries.

The third set of researches is mainly focused on clarification of state regulations' influence on a country's food security. In turn, Krajnakova, Navickas, and Kontautiene [31] mentioned that environmental regulation might be a trigger of a country's competitiveness and sustainability. Similarly, Grenˇcíková et al. [32], Bilan et al. [33–36], Lyulyov et al. [37], Akhmadeev et al. [38], Bhandari [39], Bello, Galadima, and Jibrin [40], Sokolenko, Tiutiunyk, and Leus [41], Lizi ´nska, Marks-Bielska, and Babuchowska [42], Vacca and Onishi [43], Kostyuchenko et al. [44], and Popp et al. [45] found out that di fferent environment-related institutional factors significantly influence countries' sustainability and food security.

Previous parts of the literature review proved the hypothesis that environmental (ecological) factors, in general terms, do influence a country's food security and its perspectives. Moreover, this allows the revelation that environmental responsibility is triggered by regulatory and institutional preconditions and is an essential determinant of consumer choice and agricultural business performance. Thus, it creates a background for more in-depth analysis regarding the identification of specific environmental factors that have impacts on a country's sustainable development and food security. In this perspective, it should be mentioned that Vasylyeva and Pryymenko [46], Mekhum [47], Lu et al. [48], Androniceanu and Popescu [49], Lyeonov et al. [50], Abdimomynova et al. [51], and Mentel et al. [52] clarify renewable energy production and consumption as among key environmental determinants. Additionally, Aitkazina et al. [53] pointed out that an increase in greenhouse gas emissions by agrarian enterprises and expansion of use of chemical fertilizers create threats for sustainable development and, consequently, a country's food security. Similarly, Sibanda and Ndlela [54], Dkhili and Dhiab [55], Maˇcaityte and ˙ Virbašiut¯ e [ ˙ 56], and Odermatt [57] also argue that increase of carbon emissions negatively influences company performance, countries' food security, and sustainability. In turn, Vasylieva [58] mentioned that a country's food security is dependent on yields, rational land use, development of innovations, and infrastructure. However, Aliyas, Ismail, and Alhadeedy [59] supposed that a country's food security and agricultural sustainability are based on environmental friendliness, decrease of chemical fertilizers, and e ffective ecological state policy.

Consequently, a comprehensive analysis of the theoretical and empirical research results aimed at clarifying factors a ffecting countries' food security leads to the conclusion that economic factors are still among key determinants of foodstu ff consumption (it mostly depends on prices of goods and household income) and agribusiness performance (as a key sphere of food production and distribution). At the same time, there is a considerable block of research proving that the influence of ethical, institutional, and specific environmental factors on a country's food security become more significant. In turn, among major environmental determinants a ffecting a country's food security, scientists mention water and soil usage, energetic issues (expansion of renewable and traditional energy production and consumption), greenhouse gas emission, fertilizer usage, etc. Nevertheless, the influence of these factors on a country's food security is revealed, but scientists have no unified position about the scale and character of such an impact, so it might be valuable, from both theoretical and practical perspectives, to identify which factors are more influential in the long run and which in the short run.
