| The aim of the study was to determine the potential, impact and prerequisites of localization and enhanced recycling in a rural food system, illustrated by the case of Juva milk. An interdisciplinary scenario based on the increase of local, organic milk to 50 % of milk comsumption was created and the sustainability was compared, on the basis of the statistics and data collected from the actors, with the present milk system. |

| The most well-known way to produce bioethanol is by the enzymatic hydrolysis and fermentation of starch. In a new project “BioConcens” (2007) sponsored by DARCOF (DAnish Research Center for Organic Food and farming) one aim is to develop a combined ethanol and biogas production for use in organic farming using starch containing biomass. Natural enzymes from cereals will be used for hydrolysis of starch to glucose in accordance with technology in brewing technology. Commercial enzymes are often produced from gene-modified organisms and will therefore not be used in the suggested organic context or process. A preliminary study was performed in which grains of wheat, rye, and barley were germinated using traditional methods applied in malting for beer... |

| One of the aims of organic farming is to “reduce the use of non-renewable resources (e.g. fossil fuels) to a minimum”. So far, however, only very little progress has been made to introduce renewable energy in organic farming. This paper presents energy balances of Danish organic farming compared with energy balances of conventional farming. In general, the conversion to organic farming leads to a lower energy use (approximately 10% per unit of product). But the production of energy in organic farming is very low compared with the extensive utilisation of straw from conventional farming in Denmark (energy content of straw used for energy production was equivalent to 18% of total energy input in Danish agriculture in 1996). Biomass is a key energy carrier... |

| On five long-term organic dairy farms aiming at self-sufficiency with nutrients, soil concentrations of ammonium-acetate lactate extractable potassium (K-AL) and acid-soluble K was measured twice in topsoil (0-20 cm) and subsoil (20-40 cm) over periods of 6-14 years. Organic management had occurred for >9 years at the second sampling. On average there were most probably field level K-deficits. Even so, topsoil K-AL concentrations were medium high (65-155 mg K kg–1 soil), and did not decrease during the study period. However, for three farms, topsoil K-AL was approaching a minimum level determined by soil texture, where further decrease is slow. Subsoil K-AL concentrations were generally low (<65). The soils were mostly light-textured, and reserves of... |

| Die Auswirkungen der Biogaserzeugung auf den gesamten ökologisch bewirtschafteten Betrieb sind bisher noch wenig untersucht. Durch dieses Fachgespräch sollen Praxiserfahrungen und Forschungsergebnisse zur Biogaserzeugung zusammengetragen werden. An der Diskussion werden sowohl Praktiker und Wissenschaftler als auch Administration und technische Entwicklung beteiligt sein. Ziel ist es, Regelungslücken zu schließen und für die Praxis Handlungsempfehlungen auszusprechen. Aus den verbleibenden offenen Fragen wird zukünftiger Forschungsbedarf abgeleitet. Die Ergebnisse des Fachgespräches werden für die Praxis aufbereitet und stehen als Handlungsempfehlung zur Verfügung. |

| The food system is now even more based on cheap crude oil. Every time we eat, we are all essentially ‘eating oil’. Virtually all of the processes in the modern food system are now dependent upon this finite resource which is nearing its depletion phase. Moreover, at a time when we should be making massive cuts in the emissions of greenhouse gases into the atmosphere in order to reduce the threat posed by climate change, the food system is lengthening its supply chains and increasing emissions to the point where it is a significant contributor to global warming. The organic sector should be leading the development of a sustainable food system. Direct environmental and ecological impacts of agriculture ‘on the farm’ are certainly reduced in organic... |

| This case study reviews the economic, social, and environmental benefits associated with organic agriculture in the United States. Measurable impacts are quantified by comparing indicators of benefits in counties with organic farms and counties without. Statistical differences across counties with and without organic farms provide preliminary evidence that organic farms may generate a variety of direct and indirect benefits. Of 36 indicators tested across a range of economic, social, and environmental benefits, 26 favor organic systems, three favor conventional systems, and seven are neutral. Even though organic farmers are not a large percentage of the total number of U.S. farmers, they may be influencing mainstream agriculture to shift toward greater... |

| In this report the historical background and present situation of the plant nutrient balances and surplus of plant nutrients within the agricultural sector in the eight countries of the Baltic Sea catchments area (Sweden, Finland, Estonia, Latvia, Lithuania, Poland, Denmark, Germany and Russia) are presented and analysed. The Baltic Ecological Recycling Agriculture and Society (BERAS) project is evaluating the consequences of converting the whole agricultural sector according to recycling principles. This analysis is being based on data from selected ecological recycling farms within the Baltic drainage area and will be presented in a series of project reports of which this is the first for Work Package 2, Effects on environment, natural resources and... |
