How do provisions for administrative sanctioning affect the implementation of loose legal norms? To streamline regulation, governments have increased their penal capacity by authorizing administrative sanctioning, and they have decentralized regulatory responsibility by loosening legal norms. A case study of Norway's animal welfare governance shows how using administrative sanctions to enforce loose legal norms led to unpredictable sanctioning and, thereby, subverted regulatees' trust in law enforcement. Ensuing resistance from regulatees pressured inspectors to regain legitimacy by tightening loose legal norms and by backing down on administrative sanctioning. Inspectors thus reversed streamlining policies to protect the primary purpose of their profession: to motivate compliance with animal welfare law. The case highlights unintended consequences of streamlining regulation. It also illustrates how frontline workers may protect their primary purpose by disregarding policies they perceive as disruptive.

The objective of this study was to demonstrate how height growth recalculated to periodic site index could be used to monitor and identify climatic drivers for growth variations. We used data from Norway’s National Forest Inventory (NFI), with attention to Norway spruce in the lowlands (<500 m a.s.l.) of southeastern Norway. We recalculated height growth to periodic site index and extracted a time series with annual values. We supplemented this with climatic data, i.e. monthly mean temperature, precipitation and deMartonne aridity index. The results showed that a characteristic two-peaked time series in volume growth in Norway 1994–2020 corresponded well to a time series of periodic site index for Norway spruce in the specific region mentioned above. Statistical analyses showed that for spruce, the periodic site index was higher in cold and moist summers than in warm and dry. Spruce mortality in this region tripled during 2012–22 when June temperature increased considerably, while periodic site index decreased. This corroborates warm and dry weather in June to be a main stress factor for spruce. In conclusion, periodic site index has a potential for being implemented for monitoring site productivity and for identification of climatic drivers.

Med rapporten “Grønn kunnskap 2024” presenterer Norsk institutt for bioøkonomi (NIBIO) et lite utvalg av våre bidrag til bærekraftige løsninger for jordbruk, skogbruk, forvaltning og matproduksjon. Gjennom vårt arbeid i Norge og internasjonalt, er vi opptatt av å bidra til bærekraftig verdiskapning og fremtidsrettet forvaltning av våre felles biologiske ressurser.

There is a public debate on how boreal forests can deliver climate change mitigation benefits. While most debates regarding Fennoscandian forests have centered on the contrasting effects of actively managed and old-growth unmanaged forests on carbon uptake and storage, the impact of surface albedo has often been overlooked. According to the new EU forest strategy for 2030, with aim of improving quantity and quality of forests by promoting primary old-growth forests and avoiding clear-cutting, among others, we examined how albedo across a wide age range of boreal Pinus-dominated forests develops over time after wildfire (defined as unmanaged) and clear-cutting (defined as managed). We find that albedo decreases over time after disturbance, but mainly in managed forests. Annual mean albedo in young (<30 years) managed forests (0.36±0.04) is markedly larger than in young unmanaged forests (0.18±0.04). This difference is particularly prominent during winter, when snow-covered ground is present. The mean albedo over the entire unmanaged forest-age gradient (0.17±0.05) is significantly lower (p < 0.05) than that of the managed forest-age gradient (0.23±0.10). Considering the typically higher frequency of clear-cuts compared to wildfires in Fennoscandian forests, these albedo differences would be even larger over long time scales. Our findings reveal the importance of considering the climatic cooling potential of albedo when making decisions on how to optimize future forest management in northern boreal forests to mitigate climate change.
