The global climate is warming, especially in northern regions due to high-latitude amplification. This high-latitude warming leads to range expansion with advancing tree- and forest-lines (TFLs) in the Northern Hemisphere. However, empirical studies can rarely provide a well-documented elevational expansion rate, especially for timescales longer than 40–50 years. This study provides a unique long-term dataset on TFL dynamics of Betula pubescens subsp. czerepanovii in Norway, based on a combination of resampled historical data (n = 319) and new field registrations (n = 447). Our dataset includes a total of 766 registrations from five counties in Norway. In total, the dataset contains 439 treelines and 327 forest lines, most likely representing the highest recorded TFLs for the region at the given time. For all data, both resampled and new, locality, coordinates, elevation, aspect and spatial uncertainty and the resampling/sampling methods and definitions are provided. The entire material is stored and available for download through the Global Biodiversity Information Facility (GBIF) portal. This dataset includes newly-resampled TFLs, based on 57–127-year-old registrations. The entries provide elevational changes, georeferenced localities and potential sites for monitoring climate change effects. The entries enable regional analyses of TFL dynamics on intermediate timescales, including the effect of time lags. The material is available for modelling TFL range shifts along the boreal-alpine ecotone. This dataset most likely provides the highest registered Betula pubescens subsp. czerepanovii locations within their specific regions, thus representing the contemporary ecophysiological range limits for the life-form tree. Additional high-elevation TFL sites and localities have been added to make the material suitable for future remapping and monitoring of climatic TFL dynamics.

The search for renewable and sustainable energy sources is increasing worldwide, urges the identification of biofuels from insects. The possibility of producing biodiesel and biogas from insects has gained significant attention as a better alternative to conventional fossil fuels. This approach is due to the presence of high lipid and protein contents of certain insect species, including black soldier fly larvae, mealworms and crickets, which can be cultivated on organic waste streams. Insects such as black soldier flies and mealworms require minimal water and land for cultivation, and their waste-based diet reduces environmental impacts while promoting waste valorization compared to traditional biofuel feedstocks. Insects’ lipids can be extracted and converted into biodiesel through transesterification, while the remaining biomass, rich in proteins and other organic materials, can be anaerobically digested to produce biogas. This dual production pathway not only maximizes energy output but also generates valuable by-products, such as residual organic fertilizer. This review emphasizes the potential of insect-based biofuel conversion and its recent advances. The challenges in scaling up the process, and optimizing yields are critically evaluated. The environmental and technological parameters of the entire biofuel production process from insects are discussed in terms of their sustainability aspects.

Innlegget handler om plast i biogass-verdikjeden, fra innsamling av matavfall fra husholdninger og næringen til oppførsel av plast under anaerob utråtning, og etterbehandling av biorest. Innlegget dekker både vanlig plast og bionedbrytbar plast. Hvordan kan man klare å produsere mest mulig biogass og samtidig sikre en biorest av høyest mulig kvalitet?

Dyrking og sanking i byen kan øke matsikkerhet og selvforsyning under kriser. I Ukraina er urbant landbruk både beredskap og motstandsarbeid.

The soil organic carbon (SOC) Think Tank has identified and ranked the ten most critical knowledge gaps affecting SOC stocks, based on stakeholder input and iterative validation across multiple events. These prioritized gaps reflect new insights into land use impacts, policy influences, and methodological needs, forming a foundation for targeted research and innovation.
