After 16 years since the first outbreak of Bluetongue in Italy, numerous aspects concerning the epidemiology of the disease are more understandable, especially about its spread throughout the territory and the vector dynamics. But there are still many unknown factors that do not allow us to preventively act to “contain" the disease impact at the be...

It has been almost 10 years since the Agro-meteorological Service of Sardinia has been involved in studying and monitoring desertification phenomena (Bianco et al., 2000). Desertification is meant to be a dynamic process, temporally distributed, which negatively influences ecosystems, diminishing productivity potential of natural resources. The mai...

Considerable effort has been expended in studies on a large-scale and general circulation modeling to assess climatic risk. However, downscaling to the local level to assess climate risk for agricultural areas and crops has proven difficult. In addition, there have been few attempts to account for inter-annual climate variability. To overcome these...

Il Madagascar è un paese con elevate potenzialità agricole ed ambientali favorevoli all'agricoltura, ma l'arretratezza socio-culturale ed economica non ne favorisce lo sviluppo. La povertà, lo sfruttamento incontrollato e lo scarso livello di scolarizzazione, hanno portato ad un degrado del territorio che si presenta per i 3/4 della superficie defo...

... The study area, covering about 18,300 hectares, is located in the Metropolitan City of Cagliari (Southern Sardinia, Italy), a medium-sized functional urban area characterized by three levels of fragmentation degree (i.e., low, medium, high;Palumbo et al., 2020). The area is ascribable to the Mediterranean pluvioseasonal oceanic bioclimate, with a class of continentality (strong euoceanic), four thermotypic horizons (from lower thermomediterranean to upper mesomediterranean) and five ombrothermic horizons (from lower dry to lower humid), resulting in a combination of 11 isobioclimates (Canu et al., 2015) and high climate variability (Bazzato et al., 2021b). Due to the anthropic disturbance, a gradient of land-use intensification runs roughly in a north-east/south-west direction from natural and semi-natural areas (NAT) at higher altitudes to more disturbed ones at lower altitudes (agricultural areas, AGR; urban and artificial areas, URB) ( Fig. 1; Table A.1 in Appendix). ...
... The direct quantification of aquifer recharge is a difficult task largely because recharge rates vary greatly in space and time, and thus direct measurements can only be obtained at the plot scale, for instance, from lysimeters [6][7][8]. For groundwater recharge estimation, many different methods and techniques have been developed over the years and intensively discussed in the literature [9][10][11][12] The different approaches mainly depend on the availability of data and the required level of accuracy [13], as well as on the sources and mechanisms of recharge [11]. At the regional scale, numerical modeling approaches are usually applied to assess recharge and the relationships between climate, land-use changes, and recharge [14] and references therein. ...
... Arboviruses such as bluetongue virus (BTV), Schmallenberg virus (SBV), African horse sickness virus (AHSV), epizootic hemorrhagic disease virus (EHDV), Oropouche virus (OROV), and Akabane virus (AKAV) have been isolated from diverse biting-midge species Sick et al., 2019;Pilgrim et al., 2021). BTV, in particular, has been emphasized as a severe disease associated with a high economic loss due to production declines, mass mortality in sheep, goats, and cattle, in addition to the costs of vaccination programs (Purse et al., 2015;Cappai et al., 2018;Bell-Sakyi et al., 2020). Bluetongue is a vector-borne disease highly dependent on the vector's competence (Augot and Depaquit, 2010), which can also be influenced by environmental conditions such as climate (Mayo et al., 2017;Berrayah et al., 2020). ...
... Previous studies on STRs have identified population structure in a wide sample of Sardinian WB, with the strongest signal separating the east from the northwest and the southwest when using 10 STRs [31] and further differentiation within the northwestern and eastern clusters when using 16 STRs [32]. Likewise, the climate on the island is characterized by geographic variation in the precipitation regime and extreme temperatures reached in the coldest and hottest months of the year [33,34]; water scarcity can limit food availability and extreme heat could indirectly influence piglet growth and survival [35]. Land use is also diversified, providing different levels of resource availability that influences species abundance [36]. ...
... Furthermore, the reduction of vegetation cover implies a remarkable reduction of soil protection from the rain. The mountain area of the catchment is marked by a widespread presence of woods and a moderate fire risk, while the plain is characterized by a low risk because of the great urbanization and the presence of wide agricultural areas (Mazzoleni et al. 2001;Motroni et al. 2004). ...
... L'applicazione delle tecniche di Land Evaluation richiede una particolare attenzione quando si analizzano le qualità di un territorio che derivano dalla misura di variabili dinamiche, come ad esempio le variabili meteorologiche (Rossiter, 1996). A questo proposito, in letteratura sono reperibili pochi esempi di studi in cui le normali fluttuazioni interannuali del clima sono incorporate in una metodologia di valutazione del territorio (Hudson e Birnie, 1999;Motroni et al., 2002;Duce et al., 2003). ...
... Based on the construction of agro-climatic relationships we can determine inter-annual fluctuations in production and make the assessment of sustainability of agricultural production areas. In literature there are few examples of studies, in which the normal fluctuations of inter-annual climate are incorporated into an agricultural risk assessment methodology for a territory [17,7,5 ]. On the other hand, these studies should be conducted in a dynamic way, seen in terms of the impact of climate change. ...

... The potential water deficit ''PSMD max '' is the theoretical deficit that can be measured in a field completely covered with grass, with optimal water conditions and without restrictions of evapotranspiration (Green 1963). The deficit represents the summation of the differences between the monthly precipitation and the reference evapotranspiration (Duce et al. 2003): ...
... adapted to several countries and scenarios (Veldkamp, 1979;Martínez Beltrán, 1993;Grose, 1999;Weldegiorgis, 2000;Sinclair and Dobos, 2006;Shahbazi et al., 2008) and even for wildlife (Slough, 1976). Recently, it has been used to evaluate variations in potential land use in the context of climate change (Duce et al., 2004;Brown et al., 2008;Shahbazi et al., 2009). Gallardo et al. (2002) adapted the systems of Klingebiel and Montgomery (1961) and Riquier et al. (1970), both of which have been applied in Spain on a number of occasions. ...
