Optimised contributions of green infrastructure (GI) to urban ecosystem services are strongly related to its multifunctionality. The challenge, however, is that the concept of multifunctionality still needs to be transformed into an operationalised assessment to evaluate current performance, which is instrumental in supporting spatial planning and policy strategies. Using the case of Stavanger City (Norway), the study conducted a spatial assessment of the multifunctionality of the urban green infrastructure. The study used a comprehensive set of 27 function indicators estimated for each of the 156 spatial units classified by their type, age, size, and biophysical characteristics. Correlation patterns among indicators and how the average and effective multifunctionality related to unit characteristics were analysed using correlation and multivariate approaches. The study demonstrated weak correlations between function indicators but revealed some potential trade-offs and function bundles. Notably, bundles related to tree cover (e.g. C sequestration, stormwater retention) had negative relationships with facilitation measures. There was a large overlap in functions between GI types associated with public green spaces and parks. Moreover, the characteristics of green infrastructure units, like size and age, primarily affected multifunctionality through effects on function indicators. Regarding the city-wide multifunctionality, we found some turnover and subsetting of functions among units, supporting multifunctionality at larger spatial scales. However, the average contributions from different GI types were similar. The study highlights the need to understand correlation patterns among function indicators and function bundles as critical to benefit from synergies and avoid unintentional trade-offs when designing and managing urban green areas.

The access to marine residual resources is large in Norway, yet its use in agriculture remains limited. Circulizer project aims to improve the circularity between the blue and green sector, by increasing the knowledge of the use of marine residues (i.e. fish sludge and fish silage) for biogas production and its effects on the fertilizer quality (digestate) and environment. While the quality of digestate from food waste and animal manure has been extensively studied, the impact of incorporating increasing proportions of new marine residual resources remains to be investigated. To be able to substitute mineral fertilizer with digestate derived from marine residues, farmers require knowledge of its nutrient composition and availability. In contrast, biogas plant operators need assurance of a market for both biogas and digestate before investing in new facilities. Circulizer will run lab and field scale experiments where the biogas process performance and digestate quality will be assessed. Expected outcomes are: (i) Enhancing the green transition and circularity of Norwegian food production by recycling valuable nutrients from fish production for agricultural use; (ii) Ensuring environmental safety by addressing concerns related to heavy metals and organic pollutants; (iii) Increasing the utilization of marine residual resources for biogas production; (iv) Supporting the growth of the fish farming industry in Norway by improving waste treatment and recycling options for unavoidable residual resources, thereby facilitating increased fish production and nutrient recycling

Dersom man skal bygge et biogassanlegg basert på husdyrgjødsel eller samle gjødsel fra flere gårder til et større anlegg bør man foreta en vurdering av egenskapene til gjødsla. Innholdet av organisk materiale per volum som kan omdannes til biogass vil kunne variere betydelig på gården i løpet av året og mellom gårder med ulike gjødselsystem og ulikt driftsopplegg. Dette vil igjen ha betydning for mengde produsert energi og lønnsomheten i slike anlegg. Rapporten beskriver hvordan gjødselprøver bør tas, behandles og sendes. Resultatene fra gjødselprøver tatt fra ca. 50 gårder er vurdert mot tilgjengelig informasjon for type gjødselsystemer, lagringstid og vannforbruk. Egenskapene og praktisk bruk av andre aktuelle substrater for biogassproduksjon er også beskrevet. Data fra 2 etablerte biogassanlegg er innhentet for å vise hvordan og i hvor stor grad det organiske materialet brytes ned i forbindelse med biogassprosessen.

De senaste 200 åren har en stor förändring skett i Sverige – en stor del av de ängs- och betesmarker som tidigare präglade landskapet har vuxit igen eller odlats upp till följd av ett förändrat och mer intensivt skogs- och jordbruk. Ett sätt att återställa de förlorade ängsmarkerna och gynna den biologiska mångfalden är att samla in och så med fröer från lokala växter, till exempel i vägkanter. Därför uppmärksammar vi vikten av lokala fröer och fröinsamling genom årsdagen ”Fröets dag” den 30 augusti. Fröets dag instiftades av Naturskyddsföreningen 2023.Ett sätt att återställa de förlorade ängsmarkerna och gynna den biologiska mångfalden är att samla in och så med fröer från lokala växter, till exempel i vägkanter.

Nature-based solutions (NBS) are an increasingly popular strategy to water resources management, with a growing number of research projects and policy interventions. Development, implementation, and decision on NBS for retention of water, sediments, and nutrients in the landscape often require substantial investment in data acquisition and modeling efforts. SWAT+ provides several new approaches compared to SWAT in terms of i) enhanced catchment configuration with more spatial objects, ii) improved representation of the connectivity between man-made hydrologic systems and the catchment stream network, and iii) new algorithms to implement complex rule-based management actions. These advantages make SWAT+ very suitable for simulating catchment processes in relation to NBS and for developing catchment-based tools for optimizing the type, location, and design of NBS. To further propel the simulation and optimization of NBS at the catchment scale with SWAT+, we propose establishing a community to harmonize and synergize the efforts of SWAT+ users worldwide in the field of NBS implementation and management. The envisioned SWAT+ NBS community would comprise researchers and scientists sharing a common vision, engaged in co-developing frameworks, addressing policy imperatives, co-creating knowledge, and advocating for best practices in applying the SWAT+ model for advanced NBS optimization and management. The objectives of this presentation are 1) to discuss the phases of NBS development and management at catchment scale, 2) to identify the research gaps in using SWAT+ in NBS studies, and 3) to propose a structure and a coordination framework to shape the SWAT+ NBS community.
