Abstract. Introduction. The food system requires some transformational changes which should take into account the problem of population growth, uneven distribution of consumer resources and threatening impact of the intensive agricultural development on the environment. The purpose is to study the characteristics of the developed strategic scenarios of the food system and identify the ways and directions in the rational combination of market relations with efficient resource consumption at the national level in the implementation of the scenario of open source of sustainable development for Ukraine and Greece. Results. The article deals with the present-day food system of Ukraine, its benchmarks and opportunities to solve social, economic and environmental problems and achieve sustainable development. The authors have studied possibilities and principles of agricultural producers, as well as coordination of efforts by the government and society in choosing an open source of sustainable development scenario of the national food system. Directions to promote international cooperation and implementation innovations in the agricultural sector through a combination of close market ties with the efficient and economical resource consumption have been established. Possible directions to intensify close links between the markets for certain agricultural products and prospects of import substitution have been analysed. Practical ways to shift the demand toward economical use of food resources through measures aimed at promoting healthy lifestyles, culture of healthy food consumption, reducing the availability of animal protein and foods high in salt, sugar and fat have been grounded. Potential ways to reduce urban migration through new opportunities of agricultural sector in contrast to global trends of rapid urbanisation and the experience of other countries as to the growing prestige of the farmer's work through cooperation with international organisations and free access to capital have been analysed. Conclusions. It has been found out that certain strategic scenarios of global food systems can be recognised in the early stages and best used at the national level. The considered algorithms of actions must be adapted according to the existing conditions at the tactical level and provide economic, environmental and social efficiency.

This study examines the level of awareness of organizational culture (OC) of hotel managers in middle and upper level Hotel Units (HU) in Greece. A random sample of 140 hotel managers from middle and upper Hotel Units (HU) in Greece were surveyed using the Organizational Culture Assessment Questionnaire (OCAQ), a 30-item OC scale developed by Sashkin (1997). The results indicated that the mean values of the OC factors "managing change", "achieving goals" and "cultural strength" are considered as average, while "coordinated teamwork", "customer orientation" and the total OC score are considered to be high, when compared to Sashkin (1997) norms. Further results revealed significant differences only for the "customer orientation" factor. Generally, no significant differences were found among managers of middle and upper level HU for general awareness of OC. It is concluded that the results are rather homogenous, with all HU managers placing more or less the same importance to Sashkin's five OC factors, with each HU manager reporting a rather satisfactory organizational culture.
