| Inwieweit der Zeitpunkt des Holzeinschlags und damit bestimmte Rhythmen des Mondes Einfluss auf bestimmte Holzeigenschaften haben, sollte mit der vorliegenden Untersuchung geklärt werden. Dazu wurden bei Holzproben aus 4 mal 144 Bäumen (Fichte, Esskastanie, 4 Standorte) von Fälldaten aus einem Zeitraum von 24 Wochen auf Wasserverlust, Dichte, Schwindmaß und Wasseraufnahme getestet. Die Ergebnisse zeigen Beziehungen zu synodischen und siderischen Mondzyklen, allerdings differenzierter, als es traditionelle Fällregeln formulieren. |

| Øget økologisk jordbrug kan, hvis omlægningen designes rigtigt, bidrage til udviklingen i landdistrikterne. Dette belyses med en række eksempler. En kortlægning af økologisk jordbrugs udbredelse i Danmark viser, at de områder, hvor der i dag er meget økologisk jordbrug, i vid udstrækning er sammenfaldende med de områder, hvor der er et særligt behov for udvikling i landdistrikterne. Det er således et vigtigt at belyse, hvorledes den økologiske jordbrugsproduktion bedst tilrettelægges, så den bidrager til landdistriktsudviklingen i disse områder. |

| 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... |

| Increasing efficiency in livestock production and reducing the share of animal products in human consumption are two strategies to curb the adverse environmental impacts of the livestock sector. Here,we explore the roomfor sustainable livestock production by modelling the impacts and constraints of a third strategy in which livestock feed components that compete with direct human food crop production are reduced. Thus, in the outmost scenario, animals are fed only from grassland and by-products from food production. We show that this strategy could provide sufficient food (equal amounts of human-digestible energy and a similar protein/calorie ratio as in the reference scenario for 2050) and reduce environmental impacts comparedwith the reference scenario... |

| 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... |

| 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... |

| Slurry is known as a source of ammonia (NH3), methane (CH4) and nitrous oxide (N2O) emissions. NH3 emissions depend on the pH value of the slurry and previous studies show that emissions could be reduced by lowering the pH. In order to estimate the influence of stirring on the pH and the NH3 emission potential of cattle slurry, three treatments (A not stirred, B stirred for 1 x 60 min and C stirred for 6 x 10 min per day) were compared. The results show that no positive effects of stirring cattle slurry, neither in economic nor in ecological terms, can be expected. |

| In the industrialised world, waste management systems have developed to maturity without primary concern for recycling. These systems have originally been designed to ensure human health and a high local hygienic standard. More recently environmental concerns have been the driving force behind a technological development of sewage treatment with biological removal of N, P and organic matter. This technology addresses some immediate problems in the aquatic environment, but the sewage sludge from the treatment plants contains considerable quantities of xenobiotic compounds and heavy metals, and only a fraction of the nutrients that entered the urban areas, thus making the sludge a non-attractive fertiliser source. In recent years there has been concern about... |

| I ekologiskt lantbruk accentueras betydelsen av markens mikroorganismer för åkermarkens långsiktiga produktionsförmåga. Projektets mål är att karaktärisera det mikrobiologiska tillståndet i åkermark, behandlad med kompost och rötrester från organiskt hushållsavfall, genom att relatera den genotypiska diversiteten hos några utvalda bakteriesamhällen i marken med deras aktivitet och metaboliska diversitet. Bakteriernas gener ska användas för att ge ett ”fingeravtryck” för olika jordprover samtidigt som bakteriernas aktivitet mäts. Efter gödsling med bl.a. kompost och rötrester ska vi leta efter förändringar. Två bakteriegrupper – nitrifierare och denitrifierare – har valts ut att representera bakterierna, eftersom de har två olika ekologiska nischer. En allt... |

| Large variations in numbers of faecal indicator bacteria were found irrespective of the storage time of collected human faeces. Little heat seemed generated from composting processes when bin units were stored locally in households. The low reduction in microbiological parameters and very limited temperature increase were generally corroborated by the results obtained in experiment 2 when pathogen indicators were added to thoroughly mixed faecal matter. Even though Salmonella died of rapidly the other faecal bacterial indicators survived in large numbers. We conclude, that the collection and storage of human faeces in the closed plastic bins studied here is associated with only little temperature increase and subsequent reduction in faecal bacterial... |
