The consumer demand for environmentally friendly, chemical free and healthy products, as well as concern regarding industrial agriculture’s effect on the environment has led to a significant growth of organic farming. On the other hand, organic farmers are becoming interested in direct on‐farm energy production which would lead them to independency from fossil fuels and decrease the greenhouse gas emissions from the farm. In the presented work, the idea of biogas and bioenergy production at the organic farm is investigated. This thesis is devoted to evaluate such a possibility, starting from the characterization of raw materials, through optimizing new processes and solutions and finally evaluating the whole on‐farm biorefinery concept with the help of a... |

Energy production and energy use in organic agriculture (OA) need to be addressed in order to reduce the reliance on non-renewable fossil fuels and minimize greenhouse gas (GHG) emissions. Thus, there is an obligation to find consensus between the apparent opposing aims of renewable (bio) energy production and soil fertility in OA. This project aims at designing and evaluate a combined concept for biomass and bio-energy production in OA, while considering soil fertility. |

The picture the biotechnology industry has painted of GM crops in North America is one of unqualified success, after six years of commercial growing. The objective of this report was to assess whether this image is accurate and if not what problems have occurred. We present interviews with North American farmers about their experiences of GM soya, maize and oilseed rape, and review of some of the independent research. The evidence we have gathered demonstrates that GM food crops are far from a success story. In complete contrast to the impression given by the biotechnology industry, it is clear that they have not realised most of the claimed benefits and have been a practical and economic disaster. Widespread GM contamination has severely disrupted... |

Through a concept for biorefinery of green herbage to protein feed, fertilizer and energy, the project develops a new platform for organic growth. The project will deliver solutions to the following key challenges to the organic sector: Supply of organic protein feed to monogastric livestock, improved, climate-friendly, and robust crop rotations in areas with a low density of livestock, better use efficiency of the nutrients, and higher yields. These solutions are important for the sectors credibility and legitimacy. The project applies an ambitious, holistic, whole value-chain and cross disciplinary approach with the following activities: 1) Identification of the best suited material for biorefinery through cropping trials; 2)Harvest and extraction of... |

This paper presents the findings of an assessment aimed to evaluate, in terms of cost and energy consumption, the introduction of living mulches in different organic vegetable systems producing cauliflower. The study was carried out in three European countries (IT, SLO and DK) in the frame of the InterVeg project (Core Organic II). The achievements demonstrated that, in economic terms, farmers’ choice of a specific technique, like living mulch instead of sole cropping, can be influenced by two key elements: human labor and fossil fuel consumption. Different organic systems have a different proportion in using the two inputs depending on the specific farm strategy. |

A web-based digital image analysis tool (IMAGING Crop Response Analyser) has been developed, tested and made public (www.imaging-crops.dk). This new technology makes possible objective estimations of crop-soil cover (i.e. how much crop is buried with soil) associated with post-emergence weed control with spring tine harrows, rotary hoes and other weeders. Objective estimation of crop-soil cover offers new possibilities to improve decision support of physical weed control practises with low selectivity because trade-offs between weed control and resulting injury to the associated crop now may be quantified, communicated and incorporated into models. The objective of this resentation is to suggest key parameters and research priorities for future research... |

Weed competition is one of the most serious problems in vegetable crops. Physical and cultural methods represent the only adoptable solutions in organic farming systems. A two-year (2006-08) on-farm research is being carried out to test innovative operative machines for physical weed control on a typical vegetable crop sequence in the Arno Valley (Pisa, Italy). In this work we present the first results, obtained on organic fresh market spinach (Spinacia oleracea). The new strategy is compared with the standard crop and weed management system, characterised by the use of biodegradable maize starch mulch, and with a system in which the use of improved physical methods is coupled with the use of a subterranean clover (Trifolium subterraneum) living mulch.... |

In order to evaluate new strategies for the production of renewable energy within sustainable organic agriculture, a process-simulation model for a 100 ha organic farm was developed. Data used for the model was obtained from laboratory trials, literature data, consultancy with experts, and results from the BioConcens project (http://www.bioconcens.elr.dk). Different design approaches were evaluated in order to establish the most suitable configuration. Rye grains, clover grass silage, maize silage, whey and cattle manure were selected as raw materials for co-production of fuels, feed and fertilizer at the organic farm, based on the fact that crops grown in organic agriculture act as key carbon sources whereas manure and whey were applied primarily as the... |

In recent years there has been a great deal of interest in assessing the sustainability of agriculture in terms of its social, environmental and economic impact and a number of indicators and tools are used. Measurements take place at the farm or product level and indicators can be outcome related e.g. number of butterfly species present, or management related e.g. percentage of fields with margins growing wildflowers to attract butterflies. Given its underlying ethos, the organic/ecological agriculture sector should aim to be at the forefront of sustainability. The development of assessment approaches and recent discussions within the movement have identified continuous improvement towards best practice in sustainability to be one of the important... |

A network of 42 sheep farms (including 13 in organic farming (OF)) shows that the gross margin per ewe is 24% lower in OF in the mountains because of high food costs and comparable in the lowlands because of the high level of food self-sufficiency based on the cultivation of fodder and grain; incomes are identical when structural costs are comparable. An analysis of four demonstration farms shows that, given the different conditions, specific livestock management is required depending on the presence of tillable land or not. If their proportion is limited, lambings are equally distributed between spring and autumn in order to maximise fodder self-sufficiency. When crops are possible, lambings are focused on autumn (with good sale prices), which requires... |

Since the nineties the Brazilian organic movements have been looking for alternatives to certification. They have argued that in and of itself or alone certification of family farms and small enterprise is not enough to promote either the learning processes associated with organic production or stimulate development of the local market. The discussion on a Brazilian System for Fair Trade began in 2004, and PGS were considered helpful for organizing farmers, providing guarantees and improving the market. In 2007, a draft of PGS regulation for use in organic was elaborated. The same actors who helped build the Organic System are also discussing Fair Trade System. With the help of public resources, NGOs and family farmers have established systems that... |

By 2050 human populations will reach 9 billion and 70% more food will be required. Increased agricultural production is already threatened by shortage of water, severe land degradation in existing agricultural landscapes, land-use intensification, invasive species, prospects of energy price hikes, loss of biodiversity and ecosystem services and climate change. This alignment of current and rapidly emerging problems represents a truly major set of coupled environmental, economic and social challenges for humanity . In order to develop better and more sustainable food systems, we need to make overall assessments of their effects based on multiple and varied criteria. Furthermore, if such overall multicriteria assessments are actually going to be used to... |

The objective of this research, was to quantify sustainability indicators of organic dairy farms using Automatic Milking Systems (AMS), and a comparative group of organic dairy farms using conventional milking systems (CMS). Milk yield per cow was higher for AMS farms but did not result in higher net return to management. Nitrogen surplus per ha of available land was higher for AMS farms, Animal health was unaffected by AMS use, as also most milk quality aspects; somatic cell count, clostridium spores and urea. Acid degree value (ADV), measured as free fatty acids (FFA) in the milk, was higher in milk from AMS users. Labour time was decreased by almost 50% for AMS users, to 2.3 min/cow/day. It could be concluded from quantification of selected indicators... |

Buying organic remains the best strategy for US consumers to avoid eating GM food. The voters of California have rejected the proposal to label GMO food. The proposition was narrowly lost, 47% to 53% (4,326,770 ‘Yes’ votes vs. 4,884,961 ‘No’ votes). Proposition 47 was supported by the organic sector but opposed by a coalition of GMO companies and US multinational food companies. Californians were invited to vote into law ‘The California Right to Know Genetically Engineered Food Act’. Section 1(a) declared that “California consumers have the right to know whether the foods they purchase were produced using genetic engineering”. Section 1 (e) of the proposed Act declared that “Polls consistently show that more than 90 percent of the public want to know if... |
