Two of the greatest challenges facing humanity this century are climate change and the need to produce enough energy to meet the demands of a growing and developing population. Bioenergy has been proposed as a potential significant contributor to both mitigation and adaptation, as a feedstock for delivering energy security and as a contributor to climate mitigation, through substitution of fossil fuels, thereby reducing net greenhouse gas (GHG) emissions from energy production. Second-generation bioenergy has received a lot of attention over the last decades. This thesis has used Miscanthus, willow and poplar to research potential yields of these crops in Europe. Additional synergetic effects of Miscanthus, willow and poplar, to increase soil C stocks and to reduce erosion and soil carbon losses from cropland soil were quantified and the potential for a sustainable system of second-generation bioenergy production was demonstrated. The adoption of this system will depend on economic factors and policy was shown to be one of the drivers for system change. Four insights relevant for the wider literature have been found: a) SalixFor and PopFor models are suitable tools for yield estimates and planning, b) a combination of Miscanthus, willow and poplar, depending on conditions, is a suitable approach for sustainable bioenergy production, c) when the strengths of Miscanthus, willow and poplar are actively used for their added synergies, so that d) Miscanthus, willow and poplar can reduce erosion from agricultural soils.
