Occurrence and diversity of Shiga toxin-producing Escherichia coli (STEC) in Italian Alpine raw milk cheeses and their development in the earlier stages of different cheese-making processes

Shiga toxin-producing Escherichia coli (STEC) are foodborne pathogens implicated in diseases including hemorrhagic colitis and hemolytic uremic syndrome. In the last years, an increasing number of STEC infections associated with the consumption of raw milk cheeses have been reported, contributing to raise the public awareness. The aim of this study was to assess the occurrence of STEC biotypes in raw milk cheeses from Italian Alpine region and evaluate the influence of different scalding temperatures on their development. Six out 82 (7.3%) cheeses led to the isolation of E. coli biotypes with different virulence traits (stx1, stx2 and eae genes). To evaluate the impact of scalding temperatures on STEC growth, three E. coli biotypes were spiked into milk (< 50 CFU/mL) according to the FAO and WHO recommendation. An increase in STEC counts of 3 log occurred in uncooked and semi-cooked cheeses (scalding temperature of 38 and 45 °C) while in the cooked-cheeses (54 and 56 °C) E. coli content does not exceed the 2.5 log10 CFU/g. These findings showed that raw milk cheese safety is strictly related to their production technology, highlighting the importance of the control measures at farm and dairy level to preserve the safety of these products.

Assessment of the potential correlation between Smart Readiness Indicator and energy performance in a dataset of buildings in South Tyrol

The Energy Performance of Buildings Directive introduced the Smart Readiness Indicator (SRI), a common European system for assessing buildings’ smart readiness. While not mandatory across the European Union, some countries have initiated trial phases, and several studies already examined its application in different Member States. In this work, we present the findings of an extensive application of the SRI methodology on a sample of 59 recently constructed or recently renovated high-performance buildings in South Tyrol, Italy. Our research focused on two main objectives: (1) characterizing the level of smart readiness of state-of-the-art modern buildings in the Italian Alpine region of South Tyrol, and (2) discussing the potential correlation between the level of smart readiness and building energy performance class. Specifically, the HVAC and building systems with the most widespread adoption of advanced smart technologies were identified, as well as those configurations with traditional control solutions suggesting potential for improvement. The analysis proved that the different building categories present various levels of smart readiness, which is higher for the local office buildings and lower for the residential ones. No particular correlation was found between smart readiness and energy performance class, suggesting the need of adopting the SRI to give a more comprehensive characterization of the building performances.

A multidisciplinary approach to estimating wolf population size for long-term conservation.

The wolf (Canis lupus) is among the most controversial of wildlife species. Abundance estimates are required to inform public debate and policy decisions, but obtaining them at biologically relevant scales is challenging. We developed a system for comprehensive population estimation across the Italian alpine region (100,000km2 ), involving 1513 trained operators representing 160 institutions. This extensive network allowed for coordinated genetic sample collection and landscape-level spatial capture-recapture analyses that transcended administrative boundaries to produce the first estimates of key parameters for wolf population status assessment. Wolf abundance was estimated at 952 individuals (95% credible interval 816-1120) and 135 reproductive units (i.e., packs) (95% credible interval 112-165). We also estimated that mature individuals accounted for 33-45% of the entire population. The monitoring effort was spatially estimated thereby overcoming an important limitation of citizen science data. This is an important approach for promoting wolf-human coexistence based on wolf abundance monitoring and an endorsement of large-scale harmonized conservation practices.

Archaeology of the Landscape of Metalworking Sites in Italian Alpine Areas (Orobic Alps) between the Middle Ages and the Modern Era

The article introduces features of iron-working in the north-western Italian Alpine region (specifically, the Valtellina side of the Bergamesque or Orobic Alps) during the Middle Ages by comparing historical data and archaeological sources. This will help shed light on the organisation of the production process, starting from iron ore mining, proceeding to examine the transformation phases and culminating in the conversion of the ore into ingots or bars to produce tools for agricultural or wood-cutting activities. The article follows two distinct paths, initially presenting the main stages of iron-working in Valtellina until the second half of the eighteenth century, followed by an analysis of the mining complex of Val Venina where an extremely important metal-working site is situated. Two separate mining zones were identified, the first deep underground and the second an opencast working site. Furthermore, a series of rooms made of dry-stone walling that provided accommodation for the miners have been brought to light, as well as mineral deposits and stables for the animals required to carry out the activities described by Melchiorre Gioia in his volume “Statistica del Dipartimento dell’Adda” and indicated in the land registers of the Lombardy-Veneto regions carried out in 1815 and 1863.

Evaluation of Different Scenarios to Switch the Whole Regional Bus Fleet of an Italian Alpine Region to Zero-Emission Buses

Public bus decarbonization is increasingly important to address the global issue of climate change. There are several challenges associated with large-scale introduction of zero-emission technologies in public fleets. This is especially the case in an extra-urban context, of mountain regions with challenging weather conditions. In this work the analysis of the state-of-the-art ZEBs, local bus lines, and timetables was performed to understand the best fit of technology—battery electric buses (BEBs) or fuel cell electric buses (FCEBs)—for each line in such a region. Further, a simulation tool was developed to calculate the compatibility of zero-emission technologies with the current needs of the public transportation considering distance, altitude difference, and climate conditions. The results show that a complete switch of the fleet is possible with a slight increase in the number of buses and that there is no clear difference in the distance covered in mountainous areas by BEBs versus FCEBs, but that both technologies can cover similar distances. The tool developed is not limited to bus fleets but can be applied to all kinds of fleets that cover clearly defined daily routes.

A payment scheme for the ecosystem services of mountain grasslands embedded in dairy products

Mountain pastures and meadows have been disappearing at a steady pace from the Italian Alpine and Apennine regions for the last century. Livestock farms and pastoral activities have traditionally contributed to preserving them, but they are facing increasingly adverse socio-economic and climatic trends The aim of the paper is to explore the economic feasibility of a payment scheme for grassland-based ecosystem services embedded into locally produced dairy products that can compensate farmers' effort and increase their profitability. Using the method of discrete choice experiments, we estimate Italian consumers’ willingness to pay for a set of selected attributes of mountain cheese associated with provisioning, cultural, and existence ecosystem services. Our results indicate that consumers would be willing to pay cheese 4€/kg to 6€/kg more for each increase in the level of ecosystemic attributes, thus supporting the introduction of a payment scheme as a local and scalable policy intervention.

External Benefits of Irrigation in Mountain Areas: Stakeholder Perceptions and Water Policy Implications

Irrigation contributes to land and ecosystem degradation, especially in intensive farming areas. However, in marginal areas, long-established irrigation systems also supply agroecosystem services. This study aimed to identify and prioritize the external benefits provided by irrigation in extensive grazing farms in an Italian alpine region (Aosta Valley, NW Italy). Three local stakeholder groups (land irrigation consortia members, non-farmer users of the irrigation water service, and non-user citizens) engaged in focus group discussions. The transcriptions were analyzed with an integrated subjective and computer-assisted approach. The main result of the study showed that a convergence of stakeholder opinions led to prioritization of the same four benefits, i.e., hydro-geological and land maintenance, traditional agricultural landscape conservation, biodiversity conservation, and leisure recreational activities provision. Incorporating this information into decision-making processes is relevant in marginal mountain areas, especially in light of the implementation of the water pricing policy laid down in the EU Water Framework Directive. To this end, the economic value of the external benefits should be considered along with the recovery costs for water services. Such information is essential to balance the environmental costs of irrigation and to compare the resource cost of alternative water uses.

The QBS-ar Index: a Sensitive Tool to Assess the Effectiveness of an Agroecological Practice in the Italian Alpine Region

The QBS-ar Index: a Sensitive Tool to Assess the Effectiveness of an Agroecological Practice in the Italian Alpine Region

Ethnomedicinal and Ethnobotanical Survey in the Aosta Valley Side of the Gran Paradiso National Park (Western Alps, Italy).

Most of traditional knowledge about plants and their uses is fast disappearing because of socio-economic and land use changes. This trend is also occurring in bio-cultural refugia, such as mountain areas. New data on Traditional Ethnobotanical Knowledge (TEK) of Italian alpine regions were collected relating to three valleys (Cogne, Valsavarenche, Rhêmes) of the Gran Paradiso National Park. Extensive dialogues and semi-structured interviews with 68 native informants (30 men, 38 women; mean age 70) were carried out between 2017 and 2019. A total of 3918 reports were collected, concerning 217 taxa (including 10 mushrooms, 1 lichen) mainly used for medicinal (42%) and food (33%) purposes. Minor uses were related to liquor making (7%), domestic (7%), veterinary (5%), forage (4%), cosmetic (1%) and other (2%). Medicinal plants were used to treat 14 ailment categories, of which the most important were respiratory (22%), digestive (19%), skin (13%), musculoskeletal (10%) and genitourinary (10%) diseases. Data were also evaluated by quantitative ethnobotanical indexes. The results show a rich and alive traditional knowledge concerning plants uses in the Gran Paradiso National Park. Plants resources may provide new opportunities from the scientific point of view, for the valorization of local products for health community and for sustainable land management.

Temporal trends in abundance and phenology of migratory birds across the Italian Alps during a 20-year period

Introduction: Bird migration across mountainous regions has been studied usually at single sites due to the difficulty in employing and support a multi-site sampling effort. This may affect inference on migration whose scale is larger that a single site. The Progetto Alpi has been monitoring post-breeding bird migration through the Italian Alps with a network of several ringing stations since 1997. Until 2017, 666,471 ringing data of 191 different species were collected. Methods: Phenology of bird migration in terms of date of capture and the related elevational distribution during the sampling season (August-November) were analysed for 69 species. For a subset of 45 species the inter-annual variation in phenology along with trends in the number of ringed birds and in the ratio between the number of juveniles and adults ringed, were also analysed. Results: Migration through the Italian Alps occurred differently between species, with heterogeneity across species in the median date of capture and their elevational distribution. No linear trends in phenology were detected. For four species an annual linear increase of the ringed individuals was detected, while for other four species an annual linear decrease of the captures was detected. For two species, an increase of the ratio between the number of the juveniles and the number of adults ringed was detected. Conclusions: The long-term standardized monitoring of post-breeding migration allowed us to consolidate and increase knowledge of bird migration through Italian southern Alps. The information gathered allowed us to define the temporal and elevation distribution of passerine birds crossing the mountainous area, and to test interannual trends in the number of captures. The main purpose of this work was to report on the information collected in twenty years of field activity, providing a contribution to the understanding this complex phenomenon. Further investigations and more in-depth analyses are necessary to understand how environmental factors and species-specific eco-physiological traits interact and affect migratory strategies of passerine birds in the Italian Alpine region.

Longitudinal Assessment of Chlorpyrifos Exposure in Farmers and Residents of an Italian Alpine Region

The aim of this study was to obtain a longitudinal evaluation of the exposure to chlorpyrifos (CP) and chlorpyrifos-methyl (CPM) in agricultural workers in South Tyrol and in a residential group living in the same area. CP and CPM are widely used pesticides in agriculture. Biological monitoring of CP and CPM exposure in humans can be achieved by analyzing urinary levels of 3,5,6-trichloro-2-pyridinol (TCPy). TCPy a metabolite of CP and CPM which is produced by a two-step metabolic transformation. Between May 14th, 2014 and March 16th, 2015 we conducted a longitudinal study on 28 farmers actively working in spray pesticide treatment and 43 non-farmers living in the same agricultural area of South Tyrol (Italy). Urine samples were collected at two time points: during the pesticide treatment period and in a temporally distant season that should guarantee metabolite clearance. We developed and validated a liquid chromatography-tandem mass spectrometry (LC–MS/MS) method for the determination of urinary TCPy levels. During the treatment season, both farmers and residents showed higher TCPy levels (median = 6.8 and 6.73 ug/g creatinine, respectively) than during the non-treatment season (median = 2.54 and 3.22 ug/g creatinine, respectively), suggesting a similar effect of the pesticide spraying on both groups. However, the observed TCPy levels resulted in a daily CP and CPM intake well below the limits recommended by FAO/WHO. During the non-treatment season, non-farmers showed higher TCPy levels values than farmers, suggesting the existence of TCPy of other unmeasured sources of exposure not considered in this study. This suggests that, for a comprehensive evaluation of the risks associated with TCPy exposure, additional sources should be identified in addition to CP and CPM pesticides.

Climate Adaptation Strategies and Associated Governance Structures in Mountain Areas. The Case of the Alpine Regions

Adaptation to climate change raises important governance issues in terms of governance structures and mechanisms, stakeholders’ involvement, and links with the existing and wider-scale strategies. Notwithstanding the increasing attention at the global and European level, precise recommendations for the governance of climate change at the geographical macro-regional level are still lacking. Macro-regions span several states with some common morphological or climatic features and adopt wider-scale strategies which are not mandatory or do not take sufficient account of the specificities of any included regions. Each region is differently administered and adopts specific climate adaptation strategies for addressing just the challenges of the territories they govern, without considering the effects on the neighbouring ones. They also decentralize the climate policies towards the lowest levels of government, and this has increased the number of local bodies involved and promoted the participation of non-governmental players and citizens. Within the macro-regions, local climate conditions and their changes can be similar; however, their impacts can vary significantly at the individual territory level, and their effects can extend beyond traditional administrative boundaries. Dealing with these changes is particularly challenging in the Alpine area, which extends across 48 regions/autonomous provinces belonging to eight different European countries and is governed by three different international/transnational strategies. This territory represents a fragile ecosystem due to the current climate changes, which have influenced the climate conditions differently at the local level, as well as the richness of natural resources, and the opportunity to exploit them for economic reasons. South Tyrol (IT) is one of the autonomous provinces located in this area that is currently addressing the expected and unexpected impacts of climate change. Unlike other Italian Alpine regions, this region boasts a wider legislative autonomy, which enables the creation of more targeted climate adaptation policies and their decentralisation to the lowest level of administration, including the non-governmental players and citizens. As a result, the climate adaptation governance framework appears complex and hard to govern due to the plurality of actors and governmental levels at Alpine and regional/provincial levels. The present article sheds light on this framework, analysing specifically the three above-mentioned governance issues: governance structures, stakeholders’ involvement mechanisms, and links with the existing wider-scales strategies. While discussing these topics, it then refers specifically to South Tyrol for the case study. Based on the documental analysis of the climate adaptation strategies and resultant findings, the preferred governance mechanism for addressing the specific climate adaptation challenges of Alpine regions would involve adopting some of the regulations included in regional mono-sectoral plans. These regulations do not relate to wider-scale strategies at the macro-regional level and refer just to the administered territories. The participation of local institutions and citizens in defining and implementing these regulations is limited and not incentivized. Although important, interactions across Alpine, national, and sub-national policy domains are limited. These limitations are revealed in South Tyrol and partially also in other European Alpine regions.

Milk yield and quality of Original Brown cattle reared in Italian alpine region

The present study aimed to investigate non-genetic sources of variation of milk production and quality traits of dual-purpose Original Brown (OB) cows farmed in Italian alpine region by using milk test-day records (n = 4034). Except for milk yield and somatic cell count, all phenotypes were predicted from milk mid-infrared spectra and included traditional composition traits, coagulation properties, casein fractions, minerals and fatty acids. Data were analysed using a mixed linear model which included calving season, parity, stage of lactation and first-order interactions as fixed effects, and cow and herd-test-date as random effects. Milk yield averaged 18.07 kg/d and means of fat, protein and casein content (%) were 4.03, 3.40 and 2.68, respectively. Primiparous OB cows produced milk with a greater content of unsaturated fatty acids compared with multiparous. Except for Na, minerals content was generally greater in primiparous than multiparous cows. The comparison with the literature demonstrated that OB cows produce milk with fatty acid profile similar to that of Alpine Grey and with more favourable coagulation properties and mineral composition than Pinzgauer cows. Considering that OB milk exhibited good coagulation properties, a prerequisite for cheesemaking, strategies to valorise this endangered breed should mainly focus on the manufacturing of OB mountain cheeses. In general, results for several milk-related performance coupled with the well-known strong adaptability of the breed to extensive mountain farming systems are the starting point towards the valorisation and potential expansion of this local dual-purpose genetic resource, with the ultimate goal of contributing to its conservation. Highlights Primiparous cows showed greater mineral content compared to multiparous cows. The good milk coagulation properties and high α-CN and κ-CN of Original Brown cows milk are a prerequisite for cheesemaking efficiency. A greater content of unsaturated fatty acids was observed in primiparous than multiparous OB cows.

Present extent, features and regional distribution of Italian glaciers

Remote sensing investigations permit to map and describe at a regional scale and with a multi-temporal approach mountain glaciers. In this work, we present some results from the New Italian Glacier Inventory which we developed by analyzing high-resolution color orthophotos acquired in the timeframe 2005–2011. In particular, in this paper we focused on each Italian Alpine Region, describing in detail glacier extent and features of each mountain group. Although Italian glaciologists were the first to produce glacier inventories (developing a glacier database as early as the beginning of the 20th century), during the last three decades only regional and local glacier lists have been developed. Therefore, a comprehensive study describing the actual whole Italian glaciation has been lacking. The New Italian Glacier Inventory describes 903 glaciers covering altogether an area of 368.10 km2 ± 2%. We found that about 84% of the total number of ice bodies is composed of glaciers smaller than 0.5 km2 covering only 21% of the total area, indicating that the Italian glacier resource is spread into several small ice bodies with only few larger glaciers. A comparison between the total glacier area of the new inventory and the glacier coverage value from the CGI Inventory (1959–1962) suggests a reduction of the glacier extent of about 30%.

Future perspectives of sustainable development: An innovative planning approach to inner areas. Experience of an Italian alpine region

“Futures” studies have treated the issue of place-based approach and bioregionalism planning as tool to achieve a sustainable development in areas characterized by exclusive natural peculiarities (Gray, 2007; Tonn, English, Turner, & Hemrick, 2006). After reviewing theories and cases concerning the re-launch of this kind of territories, the study introduces the concept of inner areas (Barca, 2009). Inner areas, described as a specific territorial weak category, are central to the European and Italian debate about territorial inequality and fragmentation. However, no methods to implement processes to develop inner areas have been officially identified. With these premises, this study presents a profile of a new territorial planning model of local development based on the implementation of multi-disciplinary and multi-stakeholder processes. New perspectives on sustainable long-term development, as well as the involvement of local stakeholders in planning choices, are central to this work.The focus of the study is an Italian inner area. In this study, the collaborative action-research model proposed by Sagor (2000) is transposed from the educational context into the field of sustainable regional planning for the first time. The aim is to suggest a sustainable local development pathway, by considering together local economic, naturalistic and cultural resources.The research demonstrates that a place-based approach for developing inner areas is achievable thanks to a multidisplinary and multistakeholder approach to territorial planning, aimed at reducing marginality (Pateman, 2011) and stimulating local economy (Sharma, 2000). The lessons learnt by the planning experience are analysed and the possible application of the Sagor model in future planning experiences is discussed.

FINE SPATIAL SCALE MODELLING OF TRENTINO PAST FOREST LANDSCAPE (TRENTINOLAND): A CASE STUDY OF FOSS APPLICATION

Abstract. Trentino is an Italian alpine region (about 6200 km2) with a forest coverage exceeding 60% of its whole surface. In the past, forest landscape has changed dramatically, especially in periods of forest over-exploitation.Previous studies in some Trentino sub-regions (Val di Fassa, Paneveggio) have identified these changes and the current trend of forest growth at the expenses of open areas, such as pastures and grasslands, due to the abandonment of rural areas. This phenomenon leads to the rapid Alpine landscape change and profoundly affects the ecological features of mountain ecosystems. To be able to monitor and to take future actions about this trend it is fundamental to know in detail the historical situation of the progressive changes on the land use that occurred over Trentino.The work aims to comprehensively reconstruct the forest cover of whole Trentino at high resolution (5 m × 5 m pixels) using a series of maps spanning a long period, consisting in historical maps, aerial images, remote sensed information and historical archives. The datasets were archived, processed and analyzed using the Free and Open Source Software (FOSS) GIS GRASS and QGIS. Historical maps include Atlas Tyrolensis (dated 1770), Theresianischer Kataster (dated 1859) and Italian Kingdom Forest Map (IKFM) of 1936. The aerial imagery dataset includes aerial images taken in 1954, which have been orthorectified during this research, and orthophotos available for years 1973, 1994, 2000, 2006, 2010 and 2016. Remote sensed information includes Landsat and recent Lidar data, while historical archives consist mostly in Forest Management Plans available since around 1950.The versatility of the wide variety of modules supplied from the FOSS GRASS and QGIS enabled to perform a diverse set of analysis and pre-processing (e.g.:orthorectification) on a heterogeneous dataset of input images. We will focus on the different strategies and methodologies implemented in the FOSS GIS used to process the various types of geographic data, challenges for the future of the research and the fundamental role of the FOSS systems in this process.Quantifying forest change in the time-span of our dataset can be used to perform further analysis on ecosystem services, such as protection from soil erosion, and on modification of biome diversity and to create future change scenarios.

Are non-industrial private forest owners willing to deliver regulation ecosystem services? Insights from an alpine case

As non-industrial private forest owners own a large share of forests in Europe, their management choices can largely affect the delivery of forest ecosystem services of different types: provisional, regulation and cultural. The literature is rich in studies exploring the delivery of both provisional services (timber or wood products) and cultural ones (recreation or amenity). However, fewer researches have addressed the delivery of regulation services like regulation of climate, carbon sequestration or preservation of habitats. The paper intends to contribute to this scarce literature with a Southern European case study. It analyses whether non-industrial private forest owners from an Italian alpine region would be willing to deliver additional (i.e. beyond legal requirements) quantities of regulation forest ecosystem services, whether they would do so with or without payment, and what affects such willingness. Three services are analysed: habitat improvement, soil conservation and carbon sequestration. Three multinomial logit models are estimated on a sample of 106 non-industrial forest owners. The results show, among others, that the willingness to deliver regulation forest ecosystem services is enhanced when the service impacts also on the property scale: this result concurs with the literature which shows that non-industrial private forest owners very often maximise not only their profit but also their overall utility by considering the self-consumption of services. The paper concludes by providing indications for targeting and tailoring active forest management policies focused on non-industrial forest owners of Italian alpine regions.

Risorse forestali e risorse acquifere in aree alpine

Forests are a fundamental biological purification system that allows the production of water with high quality standards at reduced costs. The water produced by forests can be considered potable or of high biological value. A study promoted by the Alpine Forests Working Group of the Alpine Convention investigated the protection of potable drinking water in the Alpine forests. Data was collected from all the Italian Alpine Regions on the presence of springs and mineral springs in the forests and on the overall forestry surface dedicated to springs safeguarding and conservation. Discussion and reflections upon forestry springs protection and management were developed with focus on particular aspects such as remuneration services, cost-benefit interventions, quality marks and hydroforestry policies

Spatial inequality in access to healthcare: evidence from an Italian Alpine region

ABSTRACTPotential access to healthcare facilities is one of the main determinants of health. This study investigates the extent of spatial inequalities in potential access to care, and the relationship between potential access and patients’ behaviour. Taking Piedmont, an Italian Alpine region, as a case study, the analysis emphasizes that potential access is not uniform within the region and lower potential access is associated with other important indicators of socioeconomic deprivation. Moreover, people living in places characterized by poor access tend to use healthcare services less often than other citizens, and to be less mobile than the rest of the population.

Identifying Habitat Type Conservation Priorities under the Habitats Directive: Application to Two Italian Biogeographical Regions

The ongoing biodiversity crisis necessitates greater efforts to ensure the adequate conservation of critical habitat types. Even though the identification of protected areas is still required in Europe, conservation efforts are now focusing on management requirements for protected areas and habitat types. Establishing effective management approaches is important for the conservation of the natural and semi-natural habitat types that are identified under the Habitats Directive framework. In this study, we propose a methodology for determining priorities in the conservation management of habitat types based on readily available data. This method relies on four simple criteria to rank habitat types, which includes: conservation condition, biodiversity value, pressure factor, and the cover relevance of habitat types (indicating regional responsibility in terms of area covered). After ranking the habitat types based on the sum of the scores given to all of the criteria, the 25% top-ranking habitat types were prioritized. The pressure factors are analyzed using cluster analysis to better convey information regarding the management needs of groups of habitat types. This prioritization method was tested in habitat types occurring within the Italian Alpine and Continental biogeographical regions. From this analysis, forests, bogs and fens, and dry grasslands were identified as conservation priorities for the Alpine region; meanwhile, a wider variety of habitat types were identified for the Continental region. Important pressure factors were identified (e.g., roads and motorways) for these two biogeographical regions of Italy, which could be used to suggest specific conservation measures. The proposed approach represents a transparent and reliable method for outlining habitat-type priorities based on conservation, biodiversity, pressure, and cover factors, which can be applied to identifying conservation measures that can help achieve biodiversity targets.
