Biogas in organic agriculture - effects on productivity, energy self-sufficiency and greenhouse gas emissions Organic Eprints
Pugesgaard, Siri; Olesen, Jørgen E.; Dalgaard, Tommy; Jørgensen, Uffe.
Reduction in the dependency on fossil fuels has been identified as one of the important areas for development of organic farming in Denmark (ICROFS, 2008). The increased public awareness on the need for actions against global warming has brought Green House Gas (GHG) emissions and the use of fossil fuels into focus in the agricultural organisations in general as well as in the organic agricultural organisations. Several scenarios for biogas production in organic agriculture could be imagined. The implementation of biogas production on organic farms and the effect of this implementation depend on the existing farming system, how the implementation is done and how this changes the farming system. Therefore the aim of this paper is to focus specifically...

Energy and emergy evaluation of potentials for energy self-sufficiency in Danish organic dairy farms by production of biogas and bioethanol Organic Eprints
Markussen, Mads Ville; Østergård, Hanne; Oleskowicz-Popiel, Piotr; Schmidt, Jens Ejby; Pugesgaard, Siri.
One obvious way to enhance agricultural resilience is for farms to increase self-sufficiency with necessities such as fuel, fodder and fertilizer. Our research seeks to uncover these potentials for Danish organic dairy farming. The setting is a theoretical model of a farm-cooperation of 10 farms of 100 ha each producing only milk and animals for slaughtering and being self-sufficient with fodder and fertilizer. The question is if they can be self-sufficient with energy by means of shared biogas and/ or bioethanol production facilities. The method is mapping of energy, emergy (embodied energy measured in solar energy joules) and mass flows in different scenarios, that are based on empirical data from Danish dairy farms concerning mix of crops, crop yields,...
