Content: Both global food and energy systems are increasingly faced with major challenges regarding food security and non-fossil energy provision, respectively. Organic or low-input agriculture as well as bioenergy production may contribute to securing rising food and energy needs. However, low-input agricultural systems are challenged for their lower productivity compared to high-input systems. Moreover, bioenergy systems are often criticized for their unsustainable high-input cropping systems. Consequently, innovative approaches are needed to optimize both sectors. A promising strategy may be the integration of organic or low-input agricultural systems with agricultural bioenergy production with the objective to increase both productivity and sustainability of land use systems.

This dissertation examines the opportunities and risks of integrated bioenergy production in organic and low-input agricultural systems, based on the example of two bioenergy technologies, anaerobic digestion (AD) and integrated generation of solid fuel and biogas from biomass (IFBB), by assessment of their structural framework conditions, systematic implications, as well as economic and risk performance. In a final step, the role of integrated agricultural bioenergy production within the context of the so-called sustainable intensification is debated.
