  1. 1. Constructing and contesting the legitimacy of private forest governance The case of forest certification in Sweden

    University dissertation from Umeå : Statsvetenskapliga institutionen, Umeå universitetet

    Author : Johanna Johansson; Umeå universitet.; [2013]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; accountability; corporate social responsibility; eco-labelling; forest certification; forest governance; forest practices; governance; legitimacy; national forest inventory; private governance; Sweden; voluntary standards; statskunskap; statskunskap;

    Abstract : In recent decades, political scientists have devoted substantial attention to the changing role of the state towards more inclusion of non-state actors in policymaking. This deliberative turn, or move towards governance, may signal inability to handle complex problems without cooperation with nonstate actors. READ MORE

  2. 2. Forest edge development

    University dissertation from Umeå : Statsvetenskapliga institutionen, Umeå universitetet

    Author : Björn Wiström; Sveriges lantbruksuniversitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : This thesis investigates design guidelines and management systems for the development of stationary forest edges with a graded profile in infrastructure and urban environments. The spatial restriction for the edge to move forward caused by human land use counteracts the natural dynamics and development patterns of graded forest edges. READ MORE

  4. 4. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR

    University dissertation from Chalmers University of Technology

    Author : Klas Folkesson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Övrig geovetenskap; Other earth sciences; Skogsuppskattning och skogsindelning; Forest mensuration; Fjärranalys; Remote sensing; Skogsteknik; Forest engineering; Övrig elektroteknik; elektronik och fotonik; Other electrical engineering; electronics and photonics; Miljöteknik; Environmental engineering; remote sensing; synthetic aperture radar SAR ; CARABAS; P-band; image segmentation; forest monitoring; model-based stem volume retrieval; windthrow detection;

    Abstract : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

  5. 5. Forest-Fuel Systems Comparative Analyses in a Life Cycle Perspective

    University dissertation from Östersund : Institutionen för teknik, fysik och matematik

    Author : Lisa Näslund Eriksson; Mittuniversitetet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Abstract : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. READ MORE
