Mean concentrations of pollutants and nutrients are frequently used in the classification of water bodies under the European Commission Water Framework Directive. Turbidity can be used as a proxy for several particle-associated substances. We used three years of sensor turbidity data in each of 10 Nordic streams to assess the uncertainty in the annual arithmetic mean concentration of turbidity when sampling weekly, fortnightly, or monthly. On average, weekly sampling produced an uncertainty of 17±9% for all streams, whereas monthly sampling increased this to 40±19%. We then developed a multiple linear model that shows how the uncertainty in annual mean turbidity increases with decreasing sampling frequency, decreasing catchment size, and increasing proportion of agricultural land in the catchment. As an example, a river of 800 km 2 catchment area and 20% agricultural land will need 29 samples a year to give a mean annual turbidity within 10% uncertainty, but a stream of 10 km 2 catchment area and 80% agricultural land will need 95 samples to achieve the same uncertainty. Turbidity was a suitable proxy for total phosphorus in seven of the 10 streams. The range of the annual mean total phosphorus concentration was compared with the environmental objective (good water quality) in each river. The results highlight that when the estimated mean total phosphorus concentration is close to the concentration of the environmental objective, an infrequent sampling strategy can lead to false water quality classification. .

Core rot in apple has only been considered a problem in a limited number of cultivars and has not been a focus in Norway, or in many other countries. There is currently a high demand for apple juice and cider in Norway. As core rot is not detectable on the fruit surface until the rot reaches the outer fruit flesh, it is possible for infected fruit to be used for juice without noticing the rot. Since Fusarium spp., one of the known causes of core rot, is a known producer of mycotoxins, precautionary investigations are needed. Over several seasons it was found that both pre- and postharvest rot of Fusarium spp. were common on most of the cultivars grown in Norway. As in other countries, Fusarium avenaceum has dominated so far, but Fusarium paeoniae was also identified on apple. Inoculation experiments with attached fruit and in storage were successful both in establishing core rot and detecting different mycotoxins from the fruit. There were differences between isolates of F. avenaceum in both the type of mycotoxins produced and the amount. A potential life cycle for Fusarium spp. on apple fruit in Norway is suggested, and possible ways of reducing the incidence both pre- and postharvest are discussed.

Recent crises show that Norwegian food production is vulnerable to climate change and that the Norwegian food production system lacks adaptive capacity in the face of likely climate change scenarios. In this situation we can look to local ecological knowledge as a source of inspiration for increasing agroecosystem’s resilience. In countries with a large amount of outlaying land, transhumance pastoral systems are widely practised. In Norway this is through the system which is called summer farming (Norw. stølsdrift). To study vulnerability and strengths in the summer farming community, I did a case study in Valdres, the area with the highest density of summer farms nationally. To analyse responses and coping strategies when meeting extreme weather and prolonged stressors I have studied archival documents about summer farming and conducted interviews centred on practises and development trajectories from the period before industrialisation. This study shows that adaptive community actions in Valdres has been more influenced by prolonged stress, compared to transient shocks, resulting in effective and diverse climate adaptation practises with the ability to buffer disturbances and in this way also cope when facing extreme stressors. The most important practises for the system’s ability to maintain itself are centred around the use of diverse and flexible fodder and grazing resources. In line with my findings research shows that structural changes caused by socio-political stress is experienced as more pressing for the farming community than weather-related stressors. As agricultural policy on a national scale aims to increase resilience to climate change, summer farming must be valued for strengthening the farms’ robustness and, also because farmers perceptions towards adapting to climate change can be important for adaptative community actions to be implemented.

This data paper presents a harmonized set of spatial datasets describing 60 agricultural landscapes (10 × 10 km each) generated for selected agricultural regions across six European countries—Denmark, Finland, France, Germany, the Netherlands, and Poland—within the Horizon 2020 EcoStack project. These landscape datasets were developed for use within the Animal, Landscape and Man Simulation System (ALMaSS) and applied within an integrated modeling framework designed to identify management strategies that effectively enhance multiple beneficial organisms, i.e., ecosystem service providers, within European agroecosystems. All landscape models were generated following the methodology detailed in Ziółkowska et al. (2026). Because input data availability and structure varied among countries, the full set of data sources and the processing steps required to account for national and regional specificities are documented. All inputs were harmonized to a common structure, spatial resolution, and Type of Landscape Element (TOLE) legend to support comparability across landscapes. The resulting datasets capture major gradients in farmland structure, composition, and management intensity across Europe. They can support not only agent-based simulations and scenario analyses but also ecological modeling and biodiversity assessments more broadly. All landscape models, associated files, metadata, and landscape-window selection criteria are provided in an open, citable format to facilitate reuse and further development.
