  2. 16. Bioenergy from the Swedish forest sector : a partial equilibrium analysis of supply costs and implications for the forest product markets

    Author : Mattias Carlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : As a response to policy requirements to improve energy security, and to reduce greenhouse gas emissions, the use of bioenergy in Sweden has more than doubled since 1980. In 2008 bioenergy use in Sweden amounted to 108 TWh, or 18% of the total supply of primary energy. Nearly all of this bioenergy supply originates from the domestic forest sector. READ MORE

  4. 17. Genetic structure and dispersal in plant populations

    Author : Johan Fogelqvist; Martin Lascoux; Sophie Gerber; Beng-Olle Bengtsson; Uppsala universitet; []
    Keywords : population genetics; dispersal; structure; plant; gene flow;

    Abstract : This thesis focuses on the spatial structure and methods to identify spatial structure in plants. Methods that investigate genetic structure can mainly be divided into equilibrium methods that reveal summed dispersal over many generations, and cluster methods, that reveal more recent dispersal events.

  5. 18. Spatial problems in long-term forest planning : from preferences to plans

    Author : Anu Korosuo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : In modern forest planning, it is important to account for the value of timber production and for other values of the forest. Important factors such as the protection of biodiversity, recreational use and traditional uses of forests are often connected to specific places in forests, or to the spatial structure of the forests.

  6. 19. Market structure and market power : the case of the Swedish forest sector

    Author : Mats Bergman; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The Swedish forest sector is analyzed, using methods drawing on traditional (forest) market analysis and industrial organization literature. Models based on economic theory are tested empirically with time-6eries data.Paper [1] deals with how the pulp and paper industry manages wood supply risk. READ MORE

  7. 20. Estimation of canopy structure and individual trees from laser scanning data

    Author : Eva Lindberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : During the last fifteen years, laser scanning has emerged as a data source for forest inventory. Airborne laser scanning (ALS) provides 3D data, which may be used in an automated analysis chain to estimate vegetation properties for large areas. READ MORE
