The aim of this study was to determine if it is possible to use abandoned farmland to produce biofuel and simultaneously promote an open landscape with possibilities of attractive views. Furthermore, the study aimed to present some landuse alternatives for fulfilling these desires. The study was performed on abandoned farmland of 100 ha close to Lake Siljan in Dalarna County, Sweden (Lat.60º51’N; Long.15º4’E; WGS84). View analyses were used and the costs and benefits for the implied actions were calculated. Management scenarios were developed to illustrate different options. Geographical Information System (GIS) was used to model the influence on the view. It was found that Lake Siljan would be more visible from the road/railroad if zones were opened up. The best view would be achieved if oat or other low landuses were used. A rotation system with broadleaves grown as short rotation coppice, would also improve the view compared to if nothing is done. The studied forested area of 100 ha held 9986 m3 of stemwood, which corresponded to 5900 tonnes dry weight biomass in 2005. The present value of the timber, pulpwood and biofuel was calculated to 4.6 million SEK. The revenues would be 2.8 million SEK, if cut immediately (2005). The most profitable landuse alternatives were ley, fallow and broadleaves grown as short rotation coppice. The conclusion of the study is that it is possible to combine biofuel production and the creation of an open landscape along Lake Siljan. The management scenarios presented would allow scenic views at the same time as biofuel is produced on abandoned farmland. The profitability is more questionable and the dependence on subsidies is a vulnerable system involving a risk for changing conditions. However, if non-economic values such as culture, nature, rural development and tourism are considered, the proposed actions may be profitable. This study provides a basis for outlining guiding principles for extended biofuel production. Further work is necessary to fully cover all the aspects involved in biofuel production on abandoned farmland.
