Farmers, as the first link in the agri-food value chain, are key in assuring its sustainability. Farmers’ behavior and attitudes towards implementing sustainable farm practices is influenced by their perceptions of risk affecting the farm and their household, either directly or indirectly. In this study, we elicit farmers’ perceived risk perception and preferences and test their robustness and validity using a sample of Greek smallholder farmers since they represent the majority of Greek holdings. Results suggest that farmers exhibit risk aversion in most situations of farm-level decision making. In many situations, farmers will prefer on-farm environmental sustainability strategies over other risk mitigation strategies. More specifically, higher age, higher education, farm size, proportion of rented land, and the existence of a farm succession plan reveal an increase in farmers’ preference for on-farm environmentally sustainable strategies and suggest reduced incentives towards implementing other on-farm or off-farm solutions.

Broadly consumed dietary patterns, such as the European and Western ones, are exerting pressures on biodiversity both in Europe and globally, and shifting toward a sustainable dietary pattern has thus become a must. This paper constitutes a preliminary communication of the results of a research project on the issue. In this study, the pressures of three dietary patterns (European, Western, and Mediterranean) on biodiversity are addressed in terms of land use, water use, greenhouse gas emissions, and eutrophication impact indicators. The environmental impacts are calculated based on a compositional analysis of each dietary pattern and the environmental footprints of the corresponding food groups. Food balance sheets published by the FAO are used as a basis for the compositional analysis, while the environmental footprints of each of the representative food products are retrieved from related life cycle assessment (LCA) studies. The results show that a shift from the European to the Mediterranean dietary pattern would lead to 10 m²/capita/day land savings, 240 L/capita/day water savings, 3 kg CO₂/capita/day reduction in greenhouse gas emissions, and 20 gPO₄eq/capita/day reductions in eutrophication potential. Likewise, a shift from the Western to the Mediterranean dietary pattern would lead to 18 m²/capita/day land savings, 100 L/capita/day water savings, 4 kg CO₂/capita/day reduction in greenhouse gas emissions, and 16 gPO₄eq/capita/day reduction in eutrophication potential. Based on these findings, it is clear that this shift is urgently needed as a step toward environmentally sustainable dietary patterns, such as the Mediterranean one, to preserve biodiversity for future generations.

Nowadays, consumers’ quality awareness and health consciousness drive the agri-food market towards a consumer-response food market. As a result, many producers and firms in the Euro-Mediterranean countries have opted for several quality and origin assurance schemes. Among them, a prevalent role is played by the Protected Designation of Origin (PDO) certification that constitutes a successful differentiation tool for agricultural products, and it is also widely used by Euro-Mediterranean olive oil producers due to effective contribution in promoting high-quality olive oil. After going through previous studies of PDO olive oil, this review paper investigates the general aspects and prospects of PDO olive oil products and EU relevant regulations, highlighting the socio-economic dimensions and impacts upon producers, consumers, and rural areas, and determining the gap between literature and practice with regards to PDO’s implementation and the expected benefits. Finally, the paper concludes with the main points and recommendations for further research.
