| Energiforbruget i jordbrugsproduktionen er interessant både fra et ressource synspunkt og fordi udledningen af CO2 fra forbrænding af fossil energi bidrager til drivhuseffekten. Både i målsætningerne for den danske Landsforening for økologisk jordbrug (LØJ) og i landboorganisationernes oplæg til Godt landmandsskab år 2000 indgår desuden mål om at reducere forbruget af fossil energi og få den bedst mulige energiudnyttelse. Ved en kombination af studier i økologiske og konventionelle kvægbrug og brug af standardværdier for dieselforbrug til de enkelte markoperationer er der opstillet modeller for energiforbruget i mark og stald. I energiregnskaberne indgår både det direkte (diesel + el) og det indirekte energiforbrug (f.eks. energi medgået til produktion af... |

| Organic agriculture aims at closed nutrient cycles, but currently the use of composts made of municipal waste is forbidden in Finnish organic production. The use of municipal waste composts in organic crop rotation and the risks connected with it in a long-term compost use will be studied. The experimental plots received the previous compost applications in 2000 and the plots will be treated with the same types of waste compost in 2004 and 2005. The crop rotation from 2000 onwards is: cereal cover crop+clover-grass/clover-grass/clover-grass/cereal/potato/... and so on. Waste compost effects are compared to manure compost effects and control treatments with no fertilization applied. The waste composts are to be carefully selected with only the highest... |

| The lack of specific methodologies to evaluate and monitor the impact of agricultural activities on the-biotic, abiotic and socio-economic environment constitutes a technical - scientific barrier for the development and improvement of Organic Agriculture in Colombia. The proposed methodology consists of: Step 1: Gathering of information on the organic production system by means of surveys and interviews with farmers. Step 2: Characterisation and description of the production system. Step 3: Qualification and quantification of the production system. Step 4: Identification and evaluation of environmental quality indicators and creation of diagrams Step 5: Interpretation of results. This proposal is a first approach for a complete evaluation... |

| Biological treatment of organic waste by aerobic composting and anaerobic digestion (biogas production) was compared with respect to a number of environmental effects and sustainability criterias including energy balance, nutrient recycling, global warming mitigation potential, emission of xenobiotic compounds and economy. The parameters were assessed based on case studies in the literature as well as our own research. Assessment of energy balance, nutrient recycling and global warming came out in favour of biogas production, but especially the results regarding estimation of global warming mitigation differ according to the assumptions made. Our calculations showed that a fugitive loss of approx. 14% of the biogas produced by anaerobic digestion will turn... |

| 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. |

| In this chapter, the interdisciplinary synthesis of the results of the BERAS project is presented and discussed. First, the effects of localisation and enhanced recycling on the ecological, economic and social dimensions of sustainability based on the case studies are reported, the cases where food systems and farms studied in their present state. Thereafter, the positive additional effects on sustainability obtainable by further promotion of localisation and recycling in the cases are suggested. The impact of total conversion to recycling organic agriculture is then considered. Obstacles to and solutions for localisation and recycling are identified. An finally, on the basis of these, conclusions about the sustainable way to localise and recycle are... |

| 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... |

| Dairy cows are very efficient in converting fibrous forages into nutritious foods for humans. However, when fed potentially human-edible feeds, such as grains and pulses, dairy cows show very low efficiency in terms of net food production. In this debate, by-products are often mentioned as high quality feeds with reduced human-edible fractions for dairy cows. The aim of this feeding trial was therefore to evaluate the effect of a full substitution of a common concentrate mixture (COM) with a mixture including solely industrial by-products (BP) on milk production, feed intake, and the edible feed conversion ratio (eFCR) in organic dairy production. Cows receiving the BP mixture showed higher intakes of fibre fractions and ether extract, while starch intake... |

| Following different crises, involving agricultural systems, either in terms of environmental pressure or of food quality and safety, an increasing need for farming system sustainability evaluation has been highlighted. How, from the research point of view, to evaluate such sustainability ? What is the methodology to mobilise ? First approaches have developed sustainability indicators to quantify the fluxes existing between the farming systems and their economical, environmental or social surroundings. However, these indicators are difficult to aggregate: each farming system is unique, so it is difficult to define reference values to reach, whatever the farm type. Such indicators are of value when they allow farmers to become aware of the impact of their... |

| The aim of the study was to assess the impact of an increased share of local organic food based on local resources, especially on increased recycling (i.e. the impact of increased locality or localization), on sustainability of rural food systems around the Baltic Sea. Obstacles and solutions for sustainable localization and recycling were also identified. In addition to these main objectives, a methodological interest in developing interdisciplinary research processes was also incorporated. Case food systems in eight Baltic countries were studied on the basis of interviews and stakeholder workshops, as well as by analysis of environmental indicators and economic parameters at farm and food system level by a European multidisciplinary research group.... |
