There is a pressing need for a transition toward more sustainable diets, which has become a shared priority for both consumers and businesses. Innovation is becoming increasingly widespread across all facets of the food supply chain. This innovation spans various domains related to production, including sustainable cultivation methods as well as new food technologies like gene editing, new product development like functional foods, and revitalizing underutilized and genetically diverse varieties to preserve biodiversity. However, not all innovative efforts are accepted by consumers and survive in markets. The interwoven and long agri-food supply chains often obscure the feedback loop between production and consumption. Consequently, it is important to understand to what extent consumers embrace these food innovations and form new eating habits. This review aims to investigate the consumer response to novel foods, focusing on behavioral factors, which have yet to receive as much attention as sensory factors. Peer-reviewed empirical articles from the last decade are examined inductively to develop a bird’s-eye view of the behavioral barriers to and drivers of consumer acceptance of novel foods. In addition, strategies to overcome the identified challenges associated with the behavioral barriers are reviewed and examined. Based on this, the study links cognitive biases with behavioral factors influencing consumer acceptance of novel foods. This study concludes that the inconvenience associated with abandoning established eating habits is typically perceived as a loss, and avoiding this inconvenience is deemed more worth the risk than the potential gains associated with novel food consumption. This study suggests that framing and placing pro-diversity labels could serve as effective behavioral interventions for marketing strategists and food policymakers.

Underutilized crops are described as plant species that were once popular but have since been neglected by mainstream agriculture for several reasons. A widespread monoculture agricultural revolution and a tendency toward more high-yielding varieties were the main reasons for the underutilization of certain crops. Remarkably, underutilized crops have endured even without formal support, which indicates that besides their exceptional nutritional value and beneficial effects on human health they contain desirable traits that could be useful for building resilience and adaptation to climate-changing environments. As such, the re-establishment of these plants to the global food system is desired. To find solutions for overcoming the obstacles for the reintroduction of these crops and to bring the neglected species back to cultivation and utilization, a comprehensive understanding of the potential reasons for the reduced cultivation of these crops is necessary. In this article, potential reasons, causes, and conditions for the decreased cultivation and consumption of certain crops are discussed with a presentation of case studies of the following species: buckwheat, lentils, green leafy vegetables, sow thistle, grass pea, cucumber melon, and eggplant. Finally, potential solutions for overcoming the identified obstacles associated with both the cultivation and consumption of certain underutilized crops and neglected species are provided. Documented benefits of the production of various crops in agricultural production systems and the beneficial effects of increased consumption of these crops for human health should stimulate and encourage people from various disciplines, i.e., farmers, researchers, agronomists, nutritionists, and policymakers to join the efforts to bring neglected species back to cultivation and consumption.

This study aims to identify the methods and associated indicators that are commonly used in value chain analyses (VCA) and to determine the areas of interest that have been excluded. Value chain analysis generally includes four different dimensions, which are institutional/functional, economic/financial, social, and environmental. This study has two main sources of literature. The first is the guidelines and the other is case studies on value chain analysis. The case study review is limited by the time between 2000 and 2022. The results showed that the researchers mainly focused on the institutional/functional analysis of the value chain, which is the first step of the analysis. Studies were mostly concentrated on the mapping of value chains, which includes the mapping of agents, core activities, and the marketing channels and flows of products. The second important area of interest is economic/financial analysis. Value added analysis is a top research area on the economical side of the value chain (VC). Consumer behavior and financial analysis are also included in the case studies. The research on consumer behavior of the value chain analysis has focused on the preferences, attitudes, and behaviors of the consumers. Financial analysis is another area of interest which generally concentrates on the cost of intermediate inputs, total output value, net present value, internal rate of return, cash flows and cost of fixed assets, and break-even point. The social and environmental sides of the value chain have been studied with less attention. This is much more important for a sustainable food VC.

This paper defines competitiveness as the ability of a country to increase its share of domestic and export markets, especially when they have a comparative advantage in a product and can produce at a lower opportunity cost. This paper briefly covers the theoretical information on this topic and provides empirical evidence of how domestic resource cost (DRC) can determine international competitiveness. A country is said to have a comparative advantage in the production of tradable goods if that country's production is efficient; if not, then it has a comparative disadvantage. The concept of comparative advantage has two meanings: The first definition states that efficiency of production is compared to two or more trading nations, and when the nations with the lowest opportunity costs are relatively more efficient, they have a comparative advantage. The other meaning of comparative advantage refers to the efficiency of different kinds of production within the domestic economy, which are compared in terms of earnings or savings of a unit of foreign exchange. Turkey seems to have a comparative advantage in plant products that do not exhibit economies of scale and are relatively labour-intensive, i.e. fruits and vegetables eliminating border and non-tariff barriers to trade in agriculture would allow both sides to exploit their comparative advantages better.
