  1. 1. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics

    Author : Peter Mellbo; Tommy Claesson; Sirkku Sarenbo; Hans Samuelsson; Högskolan i Kalmar; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ash products; Wood ash; Leaching; Drying; Nutrient; ; Sustainable forestry; Forestry; Skogsskötsel; Miljövetenskap; Environmental Science;

    Abstract : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. READ MORE

  2. 2. Automation in forestry : development of unmanned forwarders

    Author : Ola Ringdahl; Thomas Hellström; Tomas Nordfjell; Arto Visala; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; Computer science; Datavetenskap; Forest engineering; Skogsteknik; computer and systems sciences; data- och systemvetenskap;

    Abstract : For the last 50 year, forestry operations have become more and more mechanized. In modern forestry in Europe two machines are typically used; a harvester that fells, debranches and cross-cuts the trees into logs and a forwarder that transports them to the nearest road. READ MORE

  3. 3. Carbon Balance Implications of Forest Biomass Production Potential

    Author : Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; forest management; silviculture; clear-cut forestry; continuous-cover forestry; substitution; total carbon; climate benefit; climate change; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. READ MORE

  4. 4. Gendered Performances in Swedish Forestry : Negotiating Subjectivities in Women-Only Networks

    Author : Emmeline Laszlo Ambjörnsson; Anna Storm; Gunnel Forsberg; Natasha Webster; Maureen Reed; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gender; femininity; female masculinity; feminist geography; feminist political ecology; environmental governance; forestry; neoliberalisation; collective action; postfeminism; spatiality; rurality; Sweden; Geography with Emphasis on Human Geography; geografi med kulturgeografisk inriktning;

    Abstract : Environmental resource use is intimately intertwined with gendered power relations. Overarching ideals, governance and management are shaped by the negotiation and performance of gendered subjectivities. This thesis identifies and analyses key features of such negotiations and performances in the context of contemporary Swedish forestry. READ MORE

  5. 5. Evaluating thinning practices and assessment methods for improved management in coniferous production forests in southern Sweden

    Author : Magnus Persson; Johan Bergh; Lauri Mehtätalo; Linnéuniversitetet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; thinning; within-stand variation; tree species classification; Scots pine; Norway spruce; Sentinel-2; Heureka; Precision forestry; thinning detection; basal area; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Most of our knowledge about wood production of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) and associated silvicultural guidelines are based on field experiments. READ MORE
