2. 1. Peatland Bryophytes in a Changing Environment : Ecophysiological Traits and Ecosystem Function

   Author : Gustaf Granath; Håkan Rydin; Joachim Strengbom; Steven K Rice; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; allometric scaling; chlorophyll fluorescence; competition; decomposition; flooding; mire; N concentration; nitrogen deposition; photosynthesis; succession; stoichiometry; Ecological Botany; Ekologisk botanik;

   Abstract : Peatlands are peat forming ecosystems in which not fully decomposed plant material builds up the soil. The sequestration of carbon into peat is mainly associated with the bryophyte genus Sphagnum (peat mosses), which dominate and literally form most peatlands. READ MORE

4. 2. Biogas Production from Lignocelluloses : Pretreatment, Substrate Characterization, Co-digestion and Economic Evaluation

   Author : Anna Teghammar; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; lignocellulose; pretreatment; anaerobic digestion; co-digestion; substrate characterization; economic evaluation; Biotechnology;

   Abstract : Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. READ MORE

5. 3. The Economic Value of Water in the Ganges-Brahmaputra-Meghna (GBM) River Basin

   Author : Nasima Tanveer Chowdhury; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; marginal value productivity MVP ; production function; irrigation water; boro rice; Bangladesh;

   Abstract : This study estimates the scarcity value of irrigation water to farmers of Bangladesh and compares it with that of India especially in the Ganges dependent districts of both these countries. We use a physical production function approach for our analysis. The value of water ranges from USD 0.002 to 0. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rice; Wheat; Straw; MDF; HDF; UF; MUF; MDI; Non-resin; binderless MDF; Ash; Silicon; SEM; Hot-pressing; MOR; MOE; IB; Thickness swelling; MDF properties; fibre swelling; WRV; Refining; Defibration.; NATURAL SCIENCES; NATURVETENSKAP; Chemical engineering; Kemiteknik; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik;

   Abstract : The purpose of this thesis was to develop an economical, sustainable, and environmentally friendly straw Medium Density Fibreboard (MDF) process, capable of full-scale manufacturing and to produce MDF of requested quality. The investigated straw was based on wheat (Triticum aestivum L.) and rice (Oryzae sativa L.). READ MORE

7. 5. The Role of the Forest in Climate Policy

   Author : Mathilda Eriksson; Runar Brännlund; Tommy Lundgren; Brent Sohngen; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; integrated assessment; forest carbon sequestration; forest bioenergy; avoided deforestation; afforestation; uncertainty; dynamic modeling; DICE; RICE; nationalekonomi; Economics;

   Abstract : AbstractIn Paper [I], I develop the FOR-DICE model to analyze optimal global forest carbon management. The FOR-DICE is a simple framework for assessing the role of the boreal, tropical, and temperate forests as both a source of renewable energy and a resource to sequester and store carbon. READ MORE
