1. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations
Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknikSammanfattning : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. LÄS MER
2. Consequences of alternative forest management in riparian buffer zones : a GIS analysis
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.

3. Ecosystem services from woody vegetation in East African rangelands
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Drylands cover nearly half of the Earth's land surface and are dominated by croplands and rangelands. Dryland ecosystems worldwide are affected by land degradation. Increased population pressure, climate change and unsustainable land use threaten essential ecosystem services and adversely impact people’s livelihoods and well-being. LÄS MER
4. The impact of forest management methods on the ectomycorrhizal community and implications for forest productivity in needleleaf forests
Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)Sammanfattning : Ectomycorrhizal fungi (ECM) form symbiotic relationships with trees by connecting to the roots, procuring soil nutrients in exchange for carbohydrates, and are an important contributor to plant growth. The forestry practice of clearcutting can be detrimental to the ECM community by removing its source of energy and creating unfavorable soil conditions, acutely reducing ECM diversity. LÄS MER
5. Ekonomi och virkesproduktion för hyggesfritt respektive trakthyggesbruk : en analys av ekonomiska och produktionsmässiga konsekvenser
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Skogsbruket som bedrivs i Sverige har under de senaste åren kritiserats av myndigheter och allmänheten. En ny skogsstrategi från EU har tagits fram för öka andelen skogsbruksmetoder, så som hyggesfria alternativ, som främjar den biologisk mångfalden samt minska koldioxidutsläppen från skogen och därav minska andelen trakthyggesbruk som bedrivs i dagsläget.
