Such events are more and more frequent in Italy, and in the last decades huge public investments were dedicated to risk management policies in agriculture. In order to set an adequate weather-related risk assessment, a robust analysis of the hazard is needed, which requires an agro-meteorological approach to detect the potential impacts of weather extremes on agricultural activities. With the aim of assessing the effectiveness of the current risk management policy in catching the main hazards, specific agro-meteorological indices were applied to highlight occurrence, trends, and spatial patterns of extreme events. The analysis was based on reanalysis datasets and focused on a study area in Southern Italy (Campania region) during the 1981-2021 period. The findings are reported in terms of maps and statistics aggregated at administrative unit level (5 provinces) and show a general intensification of weather extremes in the last decades, both in frequency and intensity of the events. The main indications refer to growth rates of heavy precipitation, potentially leading to flood, locally exceeding 3-4 mm/year, an increasing number of months with severe/extreme droughts, mainly concentrated during the growing season. An upward trend was also observed for days with extreme maximum temperatures, which already exceeded or approached 50% between June and September in the 1981-2021 period in most areas. Maximum temperatures above 35 °C are becoming more frequent and in the inner areas they were reached in 10 days in the 2021 summer quarter. On the other hand, no significant trends were detected for late frosts. In terms of policy implications, the results seem to suggest that some extreme weather events can no longer be considered as exceptional at the present time and in a trend perspective, making them less suitable to be addressed through the risk management tools based almost exclusively on the strategy of transferring risks (insurances and more recent mutual funds) both for farmers and for the allocation of public resources. Therefore, the need is underlined for improving the design of the risk management policies to increase farms' resilience and adaptation to climate change. Moreover, the study highlights the information potential of agro-meteorological indices in supporting evidence-based decision making in agriculture.

Black locust is in fact an excellent melliferous plant and can provide information on climate change impacts due to its large distribution throughout the world as planted and naturalized trees. This paper presents the calibration and validation of a phenological model targeted at the simulation of the whole process of black locust flowering (from BBCH 51—inflorescence of flower buds visible—to BBCH 69—end of flowering). The work relies on the phenological observations gathered in the context of IPHEN, the Italian PHEnological Network, with a broad latitudinal distribution of the observational sites (from 37.53° to 46.28° N) and a long time span, from 2010 to 2021. Phenology modeling is based on the Normal Heat Hours approach, which translates air temperature into thermal units based on a plant specific response curve. As meteo...

Considering the central role assumed by the WP5 Task Forces within the project, the current compliance of the subdomain RIs with Task Forces recommendations has been analyzed, through a specific questionnaire administered to all subdomain RIs. In light of this survey results, single RI roadmaps are presented to fill the current gaps. A particular focus is finally reserved to the ongoing subdomain use cases, which are considered a key step in developing interoperability within the subdomain.

The Strategic plans start from a "context analysis", describing the current-starting conditions. In support to the policy theme on climate change, the authors proposed a context analysis on the main agrometeorological variables and weather extreme events, both at national and subnational (NUTS1) level. This paper describes the methodological choices made and the results obtained, considering the contents required by the European Commission for the context analysis (agrometeorological indicators and an indicator of economic damages due to natural disasters). The data source chosen is ERA5, the climate reanalysis dataset produced within the Copernicus project. The study demonstrates the importance of cross-reading data on hazards and data on vulnerability for policy decisions. In pa...

Significant differences in bitter acid, oil and polyphenol content were observed for hop samples according to their origin. Gas chromatography-olfactometry analysis pointed out floral notes for Tuscany samples, where hops from Latium were characterized by spicy and resinous notes, correlated to the presence of sesquiterpenes. Differences in the molecular fingerprinting were also highlighted by Fourier–Transform Infrared Spectroscopy. The differences found in the hops were reflected in the beers, which were clearly recognized as distinct by a sensory panel. Both beer samples were mainly characterized by six aroma compounds (linalool, geraniol and β-damascenone, citronellol, 2-phenylethyl acetate, and 2-phenylethanol), three of which were potentially responsible for the geo...

In this paper, the forest area definitions used for the first Italian National Forest Inventory (IFNI85) and that of the FAO – Forest Resources Assessment 2000 (FRA2000) have been compared analysing a sample of photo-plots distributed on different regions of Italy. The differences between the forest proportions obtained applying the two definitions, due to the different minimum threshold values of crown cover and of forest size, were very little, approximately 1%. Crown cover for each sample has been computed digitizing crown limits in GIS environment to reliably assess if minimum coverage threshold was met for each classification. Moreover, the lower cover threshold value of the FAO definition makes more difficult the classification of open areas. The applicability of reliable and less time consuming procedures for crown cover measuring, based on dot grids has been evaluated. The crown cover values estimated by dot grids were similar to those obtained digitizing crown limits on the ortho-photos. This study showed that the use of the FRA2000 definition of forest for the new national forest inventory should not significantly affect the comparisons of the new inventory data with the oldest ones (IFNI85 data), moreover the new data would be comparable on the international level.

In particular soil temperature during the hottest period of the year was studied in relation to solar radiation. Together with soil moisture, these factors are thought to further differentiate the microenvironments of the dunes. Temperatures and radiation were measured in the four positions of the dune (seaward slope, crest, inward slope, hollow), 4 and 6 years after fire. The incident solar radiation varies according to exposition and inclination of the different topographical position of the dune. The daily temperature patterns at soil surface and at 2, 5 and 10 cm depth are also different in the various positions. Apart from the morphological features of the dunes, a major role seems to be played by soil moisture and by sea breezes. Soil moisture probably determines the different intensities or...
