Special Issue Information

Dear Colleagues,

Olive cultivation and olive oil production represent one of the most historically and culturally significant agri-food systems in the Mediterranean and beyond, with deep roots in traditional agronomy and increasing importance for sustainability, nutrition and rural economies. Despite centuries of practice, recent challenges such as climate change, resource scarcity and evolving consumer demands for high-quality, health-promoting products are driving transformational research across the entire olive value chain.

This Special Issue of Agriculture aims to highlight advances in olive and olive oil quality, spanning orchard management practices, cultivar selection, agronomic and environmental stress adaptation, harvesting strategies, processing technologies and consumer-oriented product innovations. We seek contributions that integrate cutting-edge science and practical applications to improve nutritional, sensory and functional properties of olive-derived products while enhancing sustainability and resilience.

We welcome original research papers, comprehensive reviews and short communications that explore precision and sustainable orchard systems, biochemical and sensory quality markers, novel extraction and processing methods, authenticity and traceability techniques, by-product valorization, and market-driven product development. Interdisciplinary studies that connect agronomy, food science, technology and consumer preferences are particularly welcome. Manuscripts addressing both fundamental mechanisms and real-world solutions shaping the future of olive oil quality are also encouraged.

Olive cultivation represents a key pillar of rural economies and cultural heritage in Mediterranean regions, including western Greece. Despite its socio-economic importance, the sector faces increasing pressures from climate change, market volatility, and technological transformation, while progress toward environmentally sustainable production remains uneven. This study investigates how olive farmers’ perceptions of carbon footprint and climate risks are influenced by their demographic characteristics. Primary data were collected through 402 structured questionnaires distributed to olive producers in the Aetolia–Acarnania region. The sample was designed to represent farmers directly engaged in olive production, ensuring the relevance and reliability of the collected data. The findings, based on descriptive statistics, reveal significant heterogeneity in producers’ perceptions of climate risks and their capacity to respond through sustainable practices. Demographic characteristics appear to play an important role in shaping awareness of carbon footprint and the potential adoption of environmentally responsible farming strategies. These results suggest that sustainability transitions in perennial cropping systems depend not only on technological availability but also on social, informational, and institutional capacities. Strengthening agricultural advisory services, farmer training, and climate adaptation strategies may therefore support the adoption of climate-smart practices in olive cultivation. Furthermore, cooperation and value-chain integration are identified as potentially important mechanisms for facilitating knowledge transfer and supporting the adoption of sustainable practices (e.g., efficient irrigation and optimized input use). However, their contribution to environmental performance and greenhouse gas mitigation cannot be directly inferred from the present perception-based analysis and should be examined in future research using appropriate quantitative or environmental assessment frameworks.

Virgin olive oil (VOO) quality is strongly influenced by olive cultivar and fruit maturity stage, yet their combined effects remain insufficiently characterized in many traditional olive-growing regions. This study evaluated the physicochemical parameters, phenolic compounds content, antioxidant activity, fatty acid profile, volatile compounds, and sensory attributes of VOOs obtained from five autochthonous cultivars of Extremadura (Spain)—‘Corniche’, ‘Manzanilla Cacereña’, ‘Morisca’, ‘Pico Limón’, and ‘Verdial de Badajoz’—harvested at three ripening stages (Green, Verging-on-ripe, and Ripe). Early harvest oils exhibited significantly higher total phenolic content (up to 478 mg/kg expressed by caffeic acid equivalent, CAE), oxidative stability (up to 188 h), intense green-fruity notes dominated by (E)-2-hexenal and (Z)-3-hexenal, and stronger bitterness and pungency. As ripening progressed, phenolic compounds and LOX-derived C6 volatiles markedly decreased, while oil yield, linoleic acid, saturated aldehydes, and oxidation markers increased in most cultivars. Cultivar-specific responses were evident: ‘Corniche’ and ‘Manzanilla Cacereña’ maintained higher oleic acid and stability, whereas ‘Morisca’ and ‘Pico Limón’ were more prone to phenolic compound loss and sensory deterioration at full ripeness. Multivariate analysis confirmed strong genotype × maturity interactions shaping oil quality. Optimal harvest timing must therefore be tailored to each cultivar to maximize phenolic content, oxidative stability, and sensory excellence while balancing industrial yield. Full article
