Perceptions of intensive forestry and multi-storey wood frames among Swedish actors
Linnaeus University, Faculty of Technology, Department of Built Environment and Energy Technology. (Sustainable built environment)
2015 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

Implementation of intensive forestry (fertilization, cultivation of non-native tree species, and clone cultivation) on part of the forested land area in Sweden and an increased construction of wood-framed multi-storey buildings can contribute to reduce the net carbon dioxide emissions of the built environment. This thesis evaluates the acceptance of and interest in intensive forestry and multi-storey wood frames among different actors, and some of the underlying reasons for their approach. The results of quantitative and qualitative studies among members of the general public, private forest owners, architects, and contracts managers in Sweden are presented in six different papers. Both intensive forestry and multi-storey wood frames lack sufficient acceptance and compliance with relevant institutions such as priorities, norms, and regulations in the eyes of the studied actors. The acceptance of intensive forestry would be larger among members of the general public if they would perceive such practices to have less negative environmental effects and perceive a greater need to increase forest growth. Among the private forest owners, the interest to cultivate non-native tree species would be larger if there were more positive attitudes towards the economic consequences. Architects and contracts managers associate multistorey wood frames with several disadvantages and uncertainties, primarily with respect to fire safety, stability, durability, and sound proofing. The contracts managers’ perceptions have stronger implications for the prospects for wood frames, than the architects’ perceptions do. Promotional activities aimed to change such perceptions may improve the prospects for more wood framed multi-storey buildings in Sweden. The path dependency of Swedish multi-storey construction however implies that such activities are not enough for multi-storey wood frames to diffuse to greater extent. Broader changes to the wider context of the decisions taken in construction projects, e.g. to policy or economic environments, which change the priorities of the construction industry actors, are needed.

Abstract [en]

The use of intensive forestry on part of the forested area in Sweden increases the production of forest biomass and enables an increased use of such biomass to mitigate climate change. However, with increasing conflicting interests in forests and forestry, the success of such a strategy depends on the public acceptance. In this paper, the results of a mail survey show that although a majority of the general public in Sweden supports measures to increase forest growth, they oppose the use of intensive forestry practices such as the cultivation of exotic tree species, clones, and forest fertilization. The acceptance of such practices is mainly influenced by the perceptions of their environmental consequences. Public acceptance was highest for forest fertilization, whereas clone cultivation was the least accepted practice.

2. Swedish private forest owners’ perceptions and intentions with respect to adopting exotic tree species

Abstract [en]

Swedish forest growth can be increased through intensive forestry practices, enabling an increased use of forest biomass for climate-change mitigation. However, the diffusion of such practices depends on the forest owners’ adoption of them. We study Swedish private forest owners’ perceptions and intentions with respect to increasing forest growth by adopting exotic tree species. The results of a mail-in questionnaire survey show that although a majority of forest owners desire increasing forest growth, most owners have only a basic understanding of exotic tree species and a smaller proportion is interested in adopting them. The intention to adopt exotics seems to depend on the perceived performance of the species with respect to the economic aspects of forest management rather than on environmental or recreational concerns. Whereas a knowledge gap among the private forest owners regarding how to increase forest growth is implied, forest owners with higher self-rated knowledge of forestry and exotics have stronger intentions to adopt such species.

Abstract [en]

Use of wood frames from sustainable forestry instead of non-wood frames in multi-storey buildings can reduce primary energy use and carbon dioxide emissions in construction. However, construction actors might have different perceptions towards wood frames than towards steel and concrete frames. Such perceptions may influence the actors' decision to adopt wood frames. In this study we use a web-based questionnaire to assess Swedish architects' perceptions, attitudes and interest towards steel, concrete and wood frames in multi-storey buildings (n = 412). Results indicate that the responding architects find concrete the most suitable frame material in buildings of 3-8 storeys, mainly because of the performance of concrete with regards to the engineering aspects (e.g. stability and fire safety) that were considered important in the choice of frame material. Although wood is considered the least suitable frame material, the overall attitude towards, and interest in, using wood is positive and related to the perceived environmental benefits of wood. This may derive from an increased discussion of and information about the environmental impact of buildings. Wood may be perceived as new and innovative while not considered as adequately proven as steel and concrete with regards to engineering aspects.
