  2. 1. Forest edge development

    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. 2. Forest water governance challenges in cross-sectoral and multi-level collaboration

    University dissertation from Umeå : Umeå University

    Author : Irina Mancheva; Katarina Eckerberg; Anna Zachrisson; Susan Baker; [2020]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Forest water; Governance; Cross-sectoral governance; Multi-level governance; Governance mode; Collaborative governance; Natural resource management; Environmental policy; Water Framework Directive;

    Abstract : Forests and water are highly interconnected with forestry practices negatively affecting forest water. In the last five decades, the Swedish state has enacted multiple policy changes and allocated significant resources towards the implementation of soft policy instruments to alleviate the effects on forest water.

    Author : Jennie Sandström; Mittuniversitetet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coarse woody debris; Dead wood; Dendrochronology; Fire history; Forest conservation; Forest structure; Log; Meta-analysis; Pine heath forest; Prescribed burning; Saproxylic fungi; Saproxylic beetles; Snag; Wood-inhabiting fungi; Aktiv skötselmetod; Bevarandebiologi; Brandhistorik; Dendrokronologi; Död ved; Hällmarkstallskog; Lågproduktiv skog; Meta-analys; Naturvård; Naturvårdsbrand; Skogsstruktur; Solbelyst död ved; Stock; Torraka; Vedlevande svamp; Vedlevande insekter; Åldersstruktur;

    Abstract : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. READ MORE

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

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Erik Blomberg; [2017]
    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.

  7. 5. On the contribution of forest bioenergy to climate change mitigation

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Olivia Cintas Sanchez; [2016]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy; forest management; climate change; energy systems.; GHG balances; forest supply; carbon budget;

    Abstract : Greenhouse gas (GHG) emissions have to be drastically reduced to keep global warming below 2 degrees. Bioenergy can play a role in climate change mitigation by substituting for fossil fuels. READ MORE
