The role of local food products in the food system of West European countries tends to increase. Currently, the economic aspects of food in most of the western world are no longer dominant in decision-making, and consumers are willing to pay more for prosocial food. The present research examines support for prosocial food among consumers in Latvia. A consumer survey conducted in Latvia (n = 1000) revealed attitudes and behavior in relation to: (a) food and shopping convenience values; (b) economic values; (c) prosocial values of food consumption (local and environmental friendly food). The purpose of the survey was to make quantitative measurements that reveal the main trends in the society of Latvia and what values are important for consumers, depending on their family status, level of education, place of residence and income level. The scientific discourse reveals that more support for prosocial food is observed among higher-income households living in a city which have children and higher education. Surprisingly, the research results did not confirm this. Although the support of this consumer segment for such food is relatively high, it is lower than that of other consumers. Perhaps the explanation should be sought in the broader context of life values, e.g., sentimental feelings caused by travel rather than belongingness to a particular place; or, it is possible that hedonism prevails in the awareness of social and ecological reality and each person’s responsibility for it, which could be further research problems.

The price-to-quality ratio of broiler chicken meat is one of the reasons why consumers use these products in their daily diet. The quality of poultry products such as meat is closely associated with the nutritional value and quality of feed fed to broilers. In composing broiler diets, the main focus is turned on crude protein (CP). Because of the trend for the poultry industry to reduce its dependence on soybean meal as a source of protein, the role of pulses in the supply of protein and energy, which could partly replace the soybean meal in poultry diets, increases. Due to considerable progress in plant breeding, the present research study used peas (Pisum sativum) of the var. ‘Bruno’ and var. ‘Pinochio’ as well as faba beans (Vicia faba minora) of the var. ‘Lielplatone’ was developed in Latvia. Higher protein diets induce a higher meat protein content, accordingly, feed proteins are hydrolyzed in the digestive system into amino acids (AA) that, after absorption, are used to form proteins and to build different body tissues. The most important AA was twofold lower in peas and faba beans than in soybean meal. Although the amount of AA in feed is not directly proportional to the content of AA in broiler chicken meat, the amount of AA in poultry feed can significantly affect an important meat quality criterion for consumers – the nutritional value of protein. Therefore, the research aimed to identify changes in AA composition and chemical composition – a qualitative property of poultry meat – as a result of adding pulses (peas and beans) to poultry diets. The research results showed that the diets with an addition of faba beans and peas had a positive effect on the level of essential amino acids (EAA) and non-essential amino acids (NEAA) in broiler meat, decreased cholesterol concentration in meat, and increased energy value of meat.

The capability of large food retail chains to respond quickly to changes in consumer behaviour and their dominant market position affects all food market players and often conflicts with the interests of national food producers, which can reduce the presence of locally sourced products in the food product mix in the country. Accordingly, the present research aims to identify the impacts of the diversification of opening hours of food supermarkets on consumer shopping habits and the implications for creating an advantage for small and medium agri-food producers in selling their products. The research applied a quantitative approach to identify the main trends in society (n = 2738), with a survey including 31 variables to quantify consumer behaviour, values, and opinions and seven socio-demographic variables. If a decision was made in Latvia to close grocery shops on Sundays or reduce their opening hours on weekends, 85% of consumers indicated that they would be unlikely to change their usual shopping location and would plan to shop at a supermarket on other days. The choice between farmers’ markets and local food shops on Sundays would be made by 45% of consumers, with more than half (53%) of them shopping at local food shops at least a few times a month. The research uniquely investigated the impact of reducing supermarket opening hours on the competitive advantage of small and medium-sized agri-food producers. The findings revealed that reducing supermarket opening hours does not confer a competitive advantage to the producers or significantly shift consumer preferences towards their products.

Bioregions are examples of true sustainable development. The desire for sustainability within local communities leads to agreements and the formation of bioregions in which sustainable development is based on practical action. This paper analyzes the concept of bioregions, emphasizing holistic approaches applied to, and relationships with, economic, environmental and social factors in pathways and the pace of specialization for the development of territories, thereby complementing the agricultural dimension and paying special attention to the application of organic farming techniques. The formation of bioregions is based on the desires of local communities, but at the same time, we believe that there are objective factors that influence the development of bioregions. Thirteen factors that could affect the creation of bioregions were selected using factors referred to in research papers, as well as by adding original ones. These factors can be divided into the sustainable agriculture and tourism groups, in which high values indicate a high potential for the formation of bioregions, as well as the intensive agriculture factor group, where high values indicate the benefits of large-scale economies that hinder the formation of bioregions. Cluster analysis identified six potential bioregions in Latvia, each with distinct socio-economic, environmental, and agricultural characteristics: the metropolitan region (dominant indicator-PIT per capita, value 890 EUR), the tourism cluster (dominant indicator—tourists served as a % of the total population, value 28%), the extensive agriculture cluster (dominant indicator—organically certified UAA, value 14,645 ha), the nature and education cluster (dominant indicator—protected areas, value 7587 ha), the intensive agriculture cluster (dominant indicator—profit from productive land, value 278 EUR ha−1), as well as a non-specialized cluster (no strongly dominant indicators). This paper describes each cluster and discusses its potential for bioregion development.
