1. 1. Estimating above ground biomass in a Salix plantation using high resolution UAV images

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Simon Nåfält; [2018]
   Nyckelord :biomass; Salix; structure from motion; unmanned aerial vehicle; allometry; point cloud; Earth and Environmental Sciences;

   Sammanfattning : In forest biomass estimations, three dimensional (3D) canopy structure data derived from images captured by unmanned aerial vehicles (UAVs), also known as drones, has shown potential due to the flexibility and cost efficiency of the method. However, little research has been done for its applicability in bioenergy forest. LÄS MER

3. 2. Biofuel plantations and isoprene emissions in Svea and Götaland

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Zahra Khais Shahid; [2017]
   Nyckelord :Isoprene; Geographical Information Systems GIS ; Short Rotation Coppice SRC ; Nitrogen dioxide NO2 ; biofuels; Earth and Environmental Sciences;

   Sammanfattning : Bioenergy as an alternative source for energy production and transportation has gained attention to mitigate greenhouse gas emissions from fossil fuels. Short Rotation Coppice (SRC) as dedicated energy crops for heat and energy production have many demonstrated and proved climatic, biodiversity and environmental benefits, but concerns regarding the occurred Land Cover Change (LCC) from agriculture land into SRC have been raised.

4. 3. Placering av energiskog i Sverige : en GIS-analys

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Katarina Crafoord; [2016]
   Nyckelord :Hybridasp; Poppel; Salix; energiskog; Sverige; GIS-analys; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

   Sammanfattning : Syftet med denna studie var att undersöka hur energiskogsodlingar är placerade i landskapet i förhållande till skogsmark, vägar och vatten och hur de fördelar sig mellan olika jordbruksproduktionsområden. Detta med fokus på energiskogssorterna salix, poppel och hybridasp i Sverige under tidsperioden 2000 till 2013. LÄS MER

5. 4. Biogenic volatile organic compound emissions from Willow trees

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Md. Ahsan Mozaffar; [2013]
   Nyckelord :atmosphere; Salix; Willow; biogenic volatile organic compounds; Isoprene; climate; BVOC; geography; physical geography; Earth and Environmental Sciences;

   Sammanfattning : In August 2012, emissions of biogenic volatile organic compounds (BVOCs) from willow (Salix) trees were measured in Lund, southern Sweden. Sweden has more than 16000 ha of short rotation willow plantations for biofuel production and willow trees are suspected to emit substantial amounts of BVOC to the atmosphere. LÄS MER

7. 5. Emissions of biogenic volatile organic compounds in a Salix biofuel plantation : field study in Grästorp (Sweden)

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Malin Broberg; [2013]
   Nyckelord :Salix; biogenic volatile organic compounds; BVOC; willow; atmosphere; soil; physical geography; Earth and Environmental Sciences;

   Sammanfattning : Biogenic volatile organic compounds (BVOCs) play an important role in the climate system by altering the oxidative capacity of the atmosphere, affecting the lifetime of methane and production of tropospheric ozone, and by contributing to formation of aerosols and clouds. Salix plants (willows) are well-documented emitters of BVOCs and this study aims to examine emissions in a Salix biofuel plantation for a better understanding of its total climate impact. LÄS MER
