- Lichen is a major forage resource for reindeer and may constitute up to 80% of a reindeer's winter diet. The reindeer grazing area in Sweden covers almost half of the country, with reindeer using mountainous areas in the summer and forested areas in the winter. Knowledge about the spatial distribution of ground lichens is important for both practical and sustainable decisionmaking purposes. Since the early 1980s, remote sensing research of lichen cover in northern environments has focused on reindeer grazing issues. The objective of the present study was to use lichen information from the Swedish Forest Inventory (NFI) for classification of satellite data into ground lichen classes. The classification procedure was focused on using of NFI plots as training sets for supervised classification of the ground lichen cover in purpose to classify areas with different lichen coverage. The present research has shown the advantage of use forest inventory plot data by assessment of three methods: mahalanobis distance (MD) classification, maximum likelihood (ML) classification and spectral mixture analysis (SMA). The results of this study demonstrate high classification accuracy of SPOT imagery in distinction between lichenabundant and lichen-poor areas by mahalanobis distance classifier (overall accuracy 84.3%, kappa=0.68). The highest classification accuracy for Landsat scene was achieved by maximumlikelihood classification (overall accuracy 76.8%, kappa=0.53). The continuation research on more detailed fragmentation of lichen cover into fractions is proposed.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Business model innovation is a process that facilitates the uptake of new and more sustainable technologies. Little research has been done to identify factors that hold back the development of new business models in the urban freight sector. This paper examines business model innovation linked to two technological innovations, heavy electric vehicles and digitization, as they were developed and introduced in the Swedish urban freight sector. Our results indicate that business model innovation fundamentally functions as a negotiation between the stakeholders that are actively engaged in the urban freight supply chain. Additionally, business model innovation and technological development are two closely related processes that influence each other, and as such they create a multilayered context for decision makers. Facing an uncertain and multifaceted reality, decision makers overlook or exclude stakeholders to decrease the number of variables that they need to consider. However, this also reduces the number of potential routes forward. Furthermore, actors that are engaged in collective business model innovation face considerable uncertainty about the responsibilities that they and other actors have toward each other. Barriers to business model innovation thus appear to be moderated not only by the strength of the relationship that exists between the actors in the urban freight supply chain but also by their ability to share a common view on the technology in question, the actor’s own function within the supply chain and their relationship to specific stakeholders.
