1. Where have all the forests gone? Quantifying pantropical deforestation drivers
Sammanfattning : Deforestation across the tropics continues to be a major source of greenhouse gas emissions and the largest threat to biodiversity on land. With strengthened commitments to reduce deforestation from countries and companies alike, it is crucial that renewed investments for reducing deforestation be guided by a sound understanding of what drives deforestation.

2. How on Earth? : Operationalizing the ecosystem service concept for sustainability
Sammanfattning : Production landscapes are at the center of many of the sustainability challenges that we face. The ecosystem service concept has risen in prominence over the last decades as a tool to support sustainable landscape management. LÄS MER
3. Trädgårdsmästarens förökningsmetoder – schema och katalog över förökningsdelar vid vegetativ förökning av fleråriga örtartade växter
Sammanfattning : The purpose of this licentiate thesis is to gather and classify information about traditional vegetative propagation of perennial herbaceous plants. This thesis is the first, self-contained part of a survey of propagation methods used by horticulturists. LÄS MER
4. Insect pollination of oilseed rape
Sammanfattning : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. LÄS MER
5. On Sustainability of Biomass for Energy and the Governance Thereof
Sammanfattning : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. LÄS MER
