In recent years, entomophagy has attracted increased attention, as it was recommended as a potential source of food by the Food and Agriculture Organization of the United Nations. In Japan, Oxya yezoensisis one of the most widely eaten insect species, but studies of its functionality as a food are limited. In this study, we reported the optimal characterization of the total phenolic compounds in methanolic extract (OME) and different fractions of OME. Additionally, the antioxidant and antiallergic activities of the OME fractions were evaluated. The results showed that the ethyl acetate-soluble fraction of OME has potential antioxidant activity, whereas the n-hexane-soluble fraction showed the strongest inhibition of β-hexosaminidase, which is one of the key factors in allergic reactions. It was concluded that phenolic compounds might contribute to the antioxidant activity while unsaturated fatty acids contribute to the antiallergy activity.

Highlight ResearchMilkfish silage  oil fatty acid profileThe quality of pure fish oil from milkfish silage (Chanos chanos)The effect of using bromelain and papain enzymesAbstractMilkfish has a high nutritional content, especially fat content. The processing of milkfish oil into pure oil has not been done much. Proper processing is needed so that the fatty acids contained in fish can be utilized optimally for pharmaceutical and medical needs. Enzyme extraction is known to extract fish oil with better quality than the heating method. The aim of this research was to study the effect of the enzymes bromelain and papain on the quality of pure fish oil from milkfish silage by treating different body parts used. The experiment was carried out with Factorial Complete Randomized Design with three replications involving two factors. The first factor was the type of enzyme using two types of enzymes, namely bromelain and papain with a concentration of 15%, the second factor used was the difference in body parts that was whole fish, flesh, and waste (head, viscera, and bones). The results showed that the type of enzyme had no significant effect on the quality of fish oil, but the different treatments of fish body parts had a significant effect on the quality of the fish oil produced. The best treatment was adapted from fish oil treated using the bromelain enzyme with the flesh. This treatment resulted in yield of 1.25%, density 0.903 g/mL, FFA content of 0.56%, and peroxide value of 7.64 meq/kg.

Abstract. National, regional and global CO2 emissions and removals from forests were estimated for the period 1990–2020 using as input the country reports of the Global Forest Resources Assessment 2020. The new Food and Agriculture Organization of the United Nations (FAO) estimates, based on a simple carbon stock change approach, update published information on net emissions and removals from forests in relation to (a) net forest conversion and (b) forest land. Results show a significant reduction in global emissions from net forest conversion over the study period, from a mean of 4.3 in 1991–2000 to 2.9 Gt CO2 yr−1 in 2016–2020. At the same time, forest land was a significant carbon sink globally but decreased in strength over the study period, from −3.5 to −2.6 Gt CO2 yr−1. Combining net forest conversion with forest land, our estimates indicated that globally forests were a small net source of CO2 to the atmosphere on average during 1990–2020, with mean net emissions of 0.4 Gt CO2 yr−1. The exception was the brief period 2011–2015, when forest land removals counterbalanced emissions from net forest conversion, resulting in a global net sink of −0.7 Gt CO2 yr−1. Importantly, the new estimates allow for the first time in the literature the characterization of forest emissions and removals for the decade just concluded, 2011–2020, showing that in this period the net contribution of forests to the atmosphere was very small, i.e., a sink of less than −0.2 Gt CO2 yr−1 – an estimate not yet reported in the literature. This near-zero balance was nonetheless the result of large global fluxes of opposite sign, namely net forest conversion emissions of 3.1 Gt CO2 yr−1 counterbalanced by net removals on forest land of −3.3 Gt CO2 yr−1. Finally, we compared our estimates with data independently reported by countries to the United Nations Framework on Climate Change, indicating close agreement between FAO and country emissions and removals estimates. Data from this study are openly available via the Zenodo portal (Tubiello, 2020), with DOI https://doi.org/10.5281/zenodo.3941973, as well as in the FAOSTAT (Food and Agriculture Organization Corporate Statistical Database) emissions database (FAO, 2021a).

Pirenaica is the most important autochthonous cattle breed within the Protected Geographic Indication (PGI) beef quality label in the Basque region, in northern Spain. The short tandem repeats (STRs) are powerful markers to elucidate forensic cases and traceability across the agri-food sector. The main objective of the present work was to study the phylogenetic relationships of Pirenaica cattle and other breeds typically raised in the region and provide the minimum number of STR markers for parentage and traceability purposes. The 30-STR panel recommended by the International Society of Animal Genetics-Food and Agriculture Organization of the United Nations (ISAG-FAO) was compared against other commercial STR panels. The 30-STR panel showed a combined matching probability of 1.89 × 10−25 and a power of exclusion for duos of 0.99998. However, commercial STR panels showed a limited efficiency for a reliable parentage analysis in Pirenaica, and at least a 21-STR panel is needed to reach a power of exclusion of 0.9999. Machine-learning analysis also demonstrated a 95% accuracy in assignments selecting the markers with the highest FST in Pirenaica individuals. Overall, the present study shows the genetic characterization of Pirenaica and its phylogeny compared with other breeds typically raised in the Basque region. Finally, a 21-STR panel with the highest FST markers is proposed for a confident parentage analysis and high traceability.

The recognition and safeguarding of agricultural heritage in Europe are new concepts that are gaining attention due to the contribution they make to sustainability. Of the 57 Globally Important Agricultural Heritage Systems (GIAHS) that exist in the world today, only six have been designated in Europe. Through a qualitative analysis of the proposal documents submitted by these six European GIAHS to the Food and Agriculture Organization of the United Nations (FAO) during the designation process, this study provides a comparative characterization of these sites supported by expert assessment. During the first phase, 24 specific sub-criteria were observed based on the five main criteria that a site has to meet in order to demonstrate its global relevance as an agricultural heritage of humanity. The relevance of the resulting sub-criteria was then assessed by a Delphi panel of experts and the validated ones were applied in an assessment of the six European sites. The European GIAHS sites are characterized by the high value of their cultural landscapes’ evolution, modeled by traditional and adaptive agriculture knowledge and practices that are promoted and maintained thanks to organized and committed social organizations. The results of structuring of sub-criteria can facilitate the application of other possible European GIAHS sites.
