“…The inclusion of legumes and cereals in agroforestry can contribute to enhanced productivity and economic sustainability in olive-based agroforestry (Panozzo et Regardless the positions of agroforestry in the literature, there have been very few studies focused on the comparative assessment of agrophysiological indicators between intercropped forage legumes and cereals with olive trees. However, numerous peer-reviewed scienti c articles have reported a wide range of ndings on the assessment of the most agronomic, environmental and socioeconomic indicators in arable intercropping system (Solomou and Sfougaris, 2021;Burgess et al 2022). One of the main novelties of this study was to assess the performance of olive-based agroforestry system by analyzing how the main agrophysiological indicators change among two different intercropping arrangements of arable crops (i.e.…”

Olive-based agroforestry could provide a sustainable solution, particularly through the implementation of cereal and legume crops in intercropping with olive trees. However, the deep assessment of agrophysiological indicators between intercropped forage legumes and cereals with olive tree is poorly documented in the literature. The aim of this field research is to assess the performance of olive-based agroforestry systems by analyzing how the main agrophysiological indicators change among two contrasting intercropping arrangements of forage arable crop. Field trials were performed during two contrasting growing seasons in a young olive grove under semi-arid climate. To further enhance our understanding of olive-agroforestry performance in terms of growth and yield; multiple agrophysiological parameters were measured in arable and olive monoculture, as well as in the olive-intercropping system with two contrasting intercropping arrangements of pea and barley. The results demonstrated that olive tree canopy significantly stimulated the growth of shoot and root of intercropped barley by increasing LAI, Shoot dry biomass (+ 56%) and both root depth (+ 19%) and width (+ 26%) compared to barley monoculture. Olive-agroforestry also enhanced barley grain and protein yield (+ 58%) during both growing seasons. Agroforestry system had additional benefits in improving the vegetative growth of intercropped olive trees by increasing soil nitrogen availability. Our findings highlight also the potential benefits of intercropping olive trees with pea in improving both fruit and oil yields in olive production. Olive-based agroforestry promotes an optimized micro-climate to effectively reduce the impact of drought on intercropped barley and improves resources use by pea under optimal conditions.

“…Durán Zuazo et al [73] and Solomou and Sfougaris [74] focused their analysis on biophysical parameters. The first team focused on the microbiochemical soil parameters, showing the potential environmental benefits of the organic system in controlling soil erosion and runoff and improving soil health restoration compared with a conventional system.…”

This study proposes a framework of environmental and energy performance indicators identified and critically evaluated within the scientific literature and the Agricultural European Database for the monitoring and evaluation of the Common Agricultural Policy of the European Union. The identified set of performance indicators encompasses the whole life cycle of agri-food systems from primary production stage until end-of-life stage in agreement with the circular economy and EU “farm to fork strategy” frameworks. In particular, the practices/goals/targets suggested in the latter (e.g., organic farming goals, more relevance assigned to plant-based diets, support for the creation of short supply chains, and reduction in food losses and waste) have guided the search for the main topics of interest in our analysis and the associated environmental and energy indicators. The results of this study evidence a proposed set of performance indicators selected from the literature among LCA and non-LCA indicators (midpoint LCA impacts, cumulative energy use, emergy accounting, and material flow accounting, among others) that could be helpful in integrating the EU CAP indicators for monitoring and evaluating efforts and achieved results toward implementing and controlling the effectiveness of the adopted “farm to fork” policy and related legislative measures, as well as the application of the circular economy model.

“…The significance of endemic plant species regarding phytoremediation should also be noted, in addition to the importance of their conservation. As an area of significant biodiversity, the Mediterranean basin features 15,000-25,000 plant species, with the endemism percentage being as high as 60% [19]. An excellent example of an endemic bio-accumulators is Alyssum serpyllifolium subsp.…”

“…The Mediterranean basin is a region of distinct climatic conditions with temporal variability and great floristic heterogeneity. Due to the high variability in landscapes paired with the warm, dry summers and cool, wet winters, the Mediterranean hosts significant plant diversity, including numerous endemic and rare plant species [17][18][19][20][21].…”

The use of contaminated soils in food production imposes the need for the reduction in heavy metals concentrations, using various techniques, in order to eliminate the toxic effects of pollution and ensure safety in the consumption of agricultural products. Phytoremediation is a promising, effective, and publicly acceptable method to remove soils’ toxicity. This study aims to investigate the current knowledge on plants’ metal tolerance mechanisms, the use of Mediterranean plants in phytoremediation, and the economic perspective for its application on large scales. A total of 166 research studies were systematically reviewed, based on the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. The findings indicate that phytoremediation has more advantages compared to other techniques. It can be a sustainable and affordable option, especially for developing countries, due to the relatively low application and maintenance costs. Many hyperaccumulating plants have been identified that can be used in soil cleansing, enhancing the applicability and replicability of the method. The selection of the appropriate plant species is based on their specific physiological characteristics to remove undesirable elements from the soils and, in certain cases, there is a preference for use of non-native species. However, such species may exhibit invasive behaviors, introducing high uncertainties and risks in the preservation of local ecosystems, especially in the Mediterranean zone, since they can have a serious impact on the environmental and ecological dynamics of the local plant communities. The use of native plants is generally more advantageous since they are better acclimated, have no effects on the local ecological balance, and can eliminate the legal restrictions for their use (seed availability, planting, etc.).
