Abstract
Europe’s Earth Observation programme for climate and environmental monitoring, Copernicus, provides ready-made thematic layers in the form of High-Resolution Layers (HRL). Examples include Water and Wetness, Small woody features, Grassland and Imperviousness. These datasets are freely available and comparable across Europe, but are they of high enough quality to be useful in national monitoring? In a collaborative project between Norway and Poland, we tested the accuracy and usefulness of these products for environmental monitoring, either alone or in combination with national data. We identified several challenges, ranging from errors in the data, difficulties finding information needed in the verification work, issues related to definitions and thresholds and the time-lag before data are available. However, the work also highlighted gaps and weaknesses in the national geographic datasets. We conclude that there is a clear need for the CLMS products. We advise caution in using the products until they have been improved but see that they have great potential for future use in environmental monitoring.

Trials were carried out in apple orchards of Emilia-Romagna and Trentino-Alto Adige in northern Italy to investigate the effects of sprinkler irrigation on possible reduction in inoculum and subsequent disease pressure of Venturia inaequalis, the ascomycete causing apple scab. In spring, volumetric spore traps were placed above apple leaf litter containing pseudothecia with ascospores of the fungus. Pseudothecia matured more rapidly in irrigated plots, and 95% of the total number of spores trapped in a season was reached on average 164 degree days (base temperature 0°C) earlier in irrigated compared with nonirrigated plots. On average for seven location/year combinations, more than 50% of the ascospores were trapped following irrigations carried out for 2 h on sunny days before a forecasted rainfall. Subsequently, a much lower number of spores were trapped on rainy days following irrigation. Field trials with scab-susceptible apple cultivars were carried out in the two regions to evaluate the efficacy of sprinkler irrigation on disease. Irrigated and nonirrigated plots were either treated with different fungicide control strategies or not treated. Irrigation significantly reduced the incidence of apple scab at both sites, and the overall number of infected leaves and fruit was reduced by more than 50%. Midday sprinkler irrigation can significantly reduce the inoculum pressure of V. inaequalis in apple orchards. This may be a sustainable management strategy, especially in areas with extended dry periods.
