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

   Author : Johanna Johansson; Carina Keskitalo; Karin Bäckstrand; Umeå universitet; []
   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; political science;

   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

4. 2. Monitoring forest damage : methods and development in Sweden

   Author : Sören Wulff; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : The aims of the work this thesis is based upon were to assess past and current methods of monitoring forest damage in Sweden and to propose key components of a new monitoring system that would be better adapted to the information requirements. A utilitarian perspective is adopted in the thesis, thus forest damage is defined as anything that reduces the vitality of trees in a forest or their economic value. READ MORE

5. 3. Inventory strategies for monitoring and evaluation of forest damage

   Author : Cornelia Roberge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Under global change, increasing stresses on forests require strategies for monitoring and mitigation of damages caused by pests and diseases. While the threats to forests increase, so do the possibilities to set up efficient monitoring programmes and detect forest damage by utilising new technologies. READ MORE

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

   Author : Klas Folkesson; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CARABAS; remote sensing; forest monitoring; model-based stem volume retrieval; image segmentation; synthetic aperture radar SAR ; P-band; 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.

7. 5. Biomass Retrieval in Topographic Boreal Forest using Polarimetric and Tomographic SAR in P- and L-band

   Author : Erik Blomberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest Biomass; Tomography; SAR; L-band; EM Modelling; P-Band;

   Abstract : Forests and their associated habitats are an integral part of Earth's biosphere and provide essential environmental services. There is an ever present need for accurate and economic monitoring of forest parameters such as biomass - of great interest both locally, for forest management and resource utilization, and globally as it represents stored atmospheric CO2 and one of the largest uncertainties in climate modelling.
