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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Perceptions of intensive forestry and multi-storey wood frames among Swedish actors

    Författare :Kerstin Hemström; Krushna Mahapatra; Ole Jess Olsen; Anders Lunnan; Linnéuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; multi-storey wood frames; intensive forestry; actor perceptions; legitimacy; path dependence; Byggteknik; Civil engineering;

    Sammanfattning : Implementation of intensive forestry (fertilization, cultivation of non-native tree species, and clone cultivation) on part of the forested land area in Sweden and an increased construction of wood-framed multi-storey buildings can contribute to reduce the net carbon dioxide emissions of the built environment. This thesis evaluates the acceptance of and interest in intensive forestry and multi-storey wood frames among different actors, and some of the underlying reasons for their approach. LÄS MER

  4. 4. Forest biomass production potential and its implications for carbon balance

    Författare :Bishnu Chandra Poudel; Mittuniversitetet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : An integrated methodological approach is used to analyse the forest biomass production potential in the Middle Norrland region of Sweden, and its use to reduce carbon emissions. Forest biomass production, forest management, biomass harvest, and forest product use are analyzed in a system perspective considering the entire resource flow chains. LÄS MER

  5. 5. En blomstrande marknad : handelsträdgårdar i Sverige 1900-1950 med fyra fallstudier i Stockholms län

    Författare :Inger Olausson; Catharina Nolin; Uppsala Sveriges lantbruksuniversitet Institutionen för ekonomi; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; HUMANITIES; HUMANIORA; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; LANTBRUKSVETENSKAPER; SAMHÄLLSVETENSKAP; HUMANIORA; AGRICULTURAL SCIENCES; SOCIAL SCIENCES; HUMANITIES; Hortikultur; Trädgårdsodling; Trädgårdshistoria; Trädgårdsekonomi; Agrarhistoria; Handelsträdgård; Trädgårdsnäring; Trädgårdsmästare; Herrgårdsträdgård;

    Sammanfattning : Avhandlingen syftar till att fördjupa förståelsen för handelsträdgårdarnas verksamhet och trädgårdsnäringens utveckling i Sverige under perioden 1900–1950. Den är ett bidrag till forskningen om den yrkesmässiga, kommersiella trädgårdsodlingens historia i Sverige efter industrialismens genombrott, vilket är ett eftersatt forskningsområde. LÄS MER
