This report summarizes the main findings of the research conducted within the CircWOOD project during the period 2026 and presents key recommendations for decision-makers towards wood reuse in the construction sector. CircWOOD aimed to enable and support a transition to a sustainable, competitive, and technologically optimized circular wood value chain through a transdisciplinary research approach. The project was carried out by five research institutions and universities, exploring technical, environmental, economic, and social dimensions in the value chain. Our research findings demonstrate potentials for wood reuse, while also highlighting a variety of practical and market-related challenges. The report presents eight key recommendations for policymakers, industry stakeholders, and other decisionmakers to drive wood reuse. Improving sorting systems and quality control for wood waste from construction and demolition activities and prioritizing deconstruction over demolition can enable reuse. Developing supporting infrastructure such as material banks, reuse centers, and logistics systems is also important. Wood reuse can create new opportunities for businesses, while continued research, better data, and AI can strengthen decision-making and support a more resource-efficient built environment.

A functional and low-impact forest road network is essential for sustainable forest management, yet maintaining such infrastructure is costly and requires monitoring tools that are reliable and simple enough for operational use. We present an automated approach to detect, map, and evaluate forest road surface deterioration, designed to support end-users, including those with limited road expertise, to indicate required maintenance actions. The system relies on data collected by the vehicle-mounted near-field sensor platform RoadSens, which integrates stereo camera imagery with GNSS-based geo-referencing to capture detailed road surface information. Collected data are processed within a monitoring and scheduling environment using a YOLOv8 object detection model trained on nearly 14,000 annotated images. The model identifies six key deterioration features: potholes, wheel ruts, gullies, washboards, stones, and vegetation. These detections are used to locate maintenance-relevant features and classify road segments into three deterioration levels based on coverage thresholds, which are then visualized through a traffic-light system. A case study on a forest road in southern Norway demonstrated the system’s ability to detect and classify maintenance needs. While performance was strong for more uniform features such as vegetation, irregular structures like wheel ruts proved more challenging, occasionally leading to misclassification of actual maintenance requirements. Nevertheless, the findings confirm the technical feasibility of integrating object detection models into data-driven forest road maintenance scheduling. Future improvements will require larger and more diverse training datasets, as well as classification frameworks tailored to local conditions and specific road-user needs.309671

Abstract
This animated short film shows how beneficial insects such as ladybirds and hoverflies can help control pests like aphids. By providing flower strips and suitable habitats in and around fields, farmers can support pollinators and natural enemies of pests — contributing to more resilient crop production over time.
Abstract
The decline of soil organic carbon (SOC) content is a major concern in agricultural soils, and reduction of tillage frequency is proposed as a measure to counteract this tendency. Here, we assessed the effect of tillage and renewal frequency on grassland SOC content based on a long–term experiment at Fureneset, Western Norway. The objective was to compare permanent and unrenewed grassland treatments with treatments ploughed and renewed 6 to 15 times from 1974 to 2016. Mean SOC content of the permanent grassland was 64 ± 9 g kg−1 (one standard deviation) at 0 to 40 cm depth and soil contained 210 Mg C ha−1, compared to 60 ± 6 g kg−1 and 190 Mg C ha−1 for grassland renewed with ploughing. Higher SOC contents were associated with reduced forage dry matter yields (DMY) of the permanent grassland, but not in frequently renewed grasslands. High SOC contents correlate with high porosity and water content, as soil properties approach those of organic soils. This may cause a wetter soil and reduced plant growth and increase soil compaction. In areas with generally high SOC contents in agricultural soils, increased carbon content due to no tillage may thus make the soils more agronomically challenging to manage

Roadside habitats have abiotic and biotic conditions that deviate from natural habitats and thus constitute “novel ecosystems” with insufficient adaptation of native biota. In roadsides, the net effect of positive and negative impacts determines population viability. This situation constitutes an “ecological trap,” when attractive habitats become demographic sinks due to locally reduced reproduction or increased mortality. The impact could be exacerbated by novel ecological factors. To investigate to what extent, for which species, and under which conditions ecological traps are actually occurring, we reviewed the effects of roadsides on plant and animal performance and population dynamics. We identified 390 relevant publications with 470 different effect cases based on a standardized literature review (2008–2018). Overall, 30% of these cases reported positive effects of roadsides on plant and animal populations, 31% of cases reported negative effects, and 39% showed no effects at all. In only 18 cases, negative effects were combined with positive ones, most often due to attractive but unsuitable habitats that constituted ecological traps. Ecological novelty was not used to interpret these effects. We conclude that there is abundant literature on ecological effects of roadsides, while specific research is needed on ecological traps, including potential effects of ecological novelty.

Roads impose several types of negative impact on landscapes and biodiversity, but may also favor some organisms by providing habitats and dispersal corridors. To prioritize, plan, design, and perform activities for promoting biodiversity in road verges, it is essential to understand which key environmental factors contribute to forming different types of roadside habitats. In this chapter, we explore relationships between biodiversity and environmental factors in road verges based on a literature review with a primary focus of vascular plants and arthropods. Roadside literature indicates a number of interacting ecological factors, which together form the roadside habitat and determine community composition. These key factors can be assigned to three groups: (1) ecological conditions such as soil, topography, and microclimate, (2) ecological processes such as vegetation succession and disturbance or management of ground and vegetation, and (3) the surrounding landscape. Based on the identified key factors, we suggest an ecological classification of roadside habitats into four major groups, namely successional roadsides, dry roadsides, tallgrass roadsides, and meadow roadsides. Trees and shrubs can occur in all groups, for example as tree avenues or hedgerows, resulting in a cross-cutting subgroup: successional/dry/tallgrass/meadow roadsides with trees and shrubs.

Road Ecology has experienced rapid growth as a field, yet significant knowledge and research gaps remain, particularly regarding underexplored impacts of roads on fauna and flora, ecosystems and landscapes, as mitigation methods and management solutions to avoid or reduce negative impacts. Here, we synthesize the key research needs identified throughout the book and emphasize topics that have received limited attention, highlighting the growing need for interdisciplinary and technologically advanced studies, and innovative statistical methodologies to assess infrastructure impacts and the combined effects of different types of infrastructures (such as roads and powerlines) on biodiversity. We highlight the need for more comprehensive studies on ecosystem functioning, evolutionary effects, and the role of roadside habitats, while calling for improvements in the cost-effectiveness of mitigation measures and large-scale assessments of road impacts. Emerging research priorities for Road Ecology include a growing emphasis on interdisciplinary and technologically advanced studies, and innovative statistical methodologies to assess infrastructure impacts and the combined effects of multiple infrastructures (such as roads and powerlines) on biodiversity. The impact of new infrastructure in areas supporting multiple migratory species is also becoming a priority issue, especially in regions where there is significant growth in infrastructure projects. Interdisciplinary efforts should prioritize strategies that balance infrastructure development with biodiversity conservation, especially in rapidly developing regions.

Faba bean ( Vicia faba L.) has great potential to contribute to sustainable agriculture and protein security globally but is known to be very sensitive to drought stress. Uncovering drought-adapted germplasm is critical for developing resilient cultivars and advancing our understanding of the mechanisms underlying stress adaptation. However, high-throughput plant phenotyping under stress conditions remain a major bottleneck in crop genetics and breeding programs. In this study, a multi-sensor indoor phenotyping platform was used to assess 44 faba bean genotypes under water deficit conditions. Standardized, monitored stress conditions were achieved by watering-by-weighing for drought onset, duration, and intensities allowing genotype-level comparisons. The genotypes showed a range of stress responses in growth and physiology, including traits such as plant height, biomass, water use efficiency (WUE), and chlorophyll fluorescence parameters. Digital biomass, derived from combined top- and side-view plant imaging, was strongly correlated with biological biomass at the experimental endpoint, validating its use as a non-destructive proxy for growth assessment in faba bean. Time-resolved generalized additive modelling further revealed genotype-specific differences in the timing and magnitude of water deficit response. Genotypes that maintained growth and WUE under water deficit conditions may serve as valuable pre-breeding materials for development of drought-adapted faba bean.
