| I min ph.d. beskæftiger jeg mig overordnet set med, hvordan økologiske fødevarenetværks integritet kan opretholdes i et marked, der er præget af vækst, konkurrence og kontinuerlig udvikling i forbrugernes krav og forventninger til producenterne? Herunder især hvordan viden værdier og tillid agerer og interagerer i fødevarenetværket, samt hvilke relationer mellem forbrugere og producenter som markedsomsætningen af de økologiske produkter skaber. I det følgende præsenteres baggrunden for problemstillingen, herunder problemerne i den moderne fødevareforsyning som økologiske fødevarenetværk reagerer imod, samt elementer af den økologiske produktionsforms historie i Danmark. Efterfølgende gennemgås nogle af de metodiske overvejelser jeg har gjort som... |

| A pratica da agricultura convencional ao longo dos tempos deixou marcas nos processos naturais do meio ambiente, a saturacao da capacidade produtiva da terra e um dos seus efeitos colaterais. O surgimento de uma nova perspectiva, a agricultura organica, no que tange ao modelo de producao, trouxe consigo a oportunidade de se avaliar comparativamente os pontos positivos e negativos de cada modelo e suas adequacoes aos diferentes contextos encontrados. A informacao da epoca em que ocorreu o aparecimento da agricultura orgânica no Brasil, ja e ponto passivo e todos concordam com a versao do surgimento da Estancia Demetria em Botucatu - SP, na decada de 70 e a partir dai, a ocorrencia do surgimento de outros pontos pelo país. Com o objetivo de conhecer o... |

| Companion planting is a small-scale intercropping practice often associated with organic or biodynamic gardening. Two garden-scale studies tested popular companion planting claims by comparing garden beds devoted entirely to one of three or more test crops (monocultures) to all possible two-crop mixtures (dicultures) of the same species. A third study evaluated effects of planting density and crop ratio in three dicultures using a novel experimental design to create gradients in both factors. All studies incorporated basil (Ocimum basilicum L.), Brussels sprout (Brassica oleracea L.), and tomato (Lycopersicum esculentum Mill.). A preliminary study also included snap bean (Phaseolus vulgaris L.), radish (Raphanus sativus L.) before Brussels sprout, and... |

| The breeding program for the Norwegian Red breed over the last 35 years has included fertility, health and functional traits in addition to milk yield and other production traits. Currently, the demands placed on individual cows are increasing particularly in regards to milk yield, dry matter intake, fertility, and longevity. The overall goal for the four studies included in this thesis was to assess the reproductive performance in modern Norwegian Red cows. In the first field study, the 60 d non return rate, pregnancy incidence, calving rate and differences between non return rate and pregnancy incidence following first artificial insemination (AI) were investigated. None of the animals were treated with reproductive hormones prior to AI. The proportion... |

| Die Gesundheit und Konstitution der Tiere ist ein entscheidender Faktor für die Ökonomie, Ökologie und Ethik von Rinderhaltungen. Ein Bewertungssystem zur vergleichbaren Erfassung der Krankheitsanfälligkeit der Einzeltiere einer Kuhherde anhand von Daten, die größtenteils auf den Milchviehbetrieben vorhanden sind, ist entwickelt worden. Hierfür wurden zunächst alle Krankheiten der Kühe einer Herde in einem definierten Zeitraum von 2 Jahren aus Stallbuchaufzeichnungen (Krankheiten und Belegdaten), Tierarztrechnungen und MLP-Daten aufgenommen und in die Hauptkrankheitsgruppen Mastitis, Erkrankungen des Bewegungsapparates, Stoffwechselstörungen und Fruchtbarkeitsprobleme eingeteilt. Dabei wurden nur konstitutionsbedingte Krankheiten gezählt, nicht aber z.B.... |

| Raw milk offered for sale within and into the European Union has to be produced according to the requirements of Commission Directive 89/362/EEC and to meet quality standards described in Council Directive 92/46/EEC. Together the regulations say many things about the quality of milk and the hygienic means of production including guidance and requirements for: - The means of production, farm specifications etc. - Processes, milk handling - Animal health - Milk composition related to quality - especially antibiotics, cell count and bacterial content (Hillerton & Berry, 2004) Unpasteurized milk and the associated food products (yogurt, butter, cheese etc.) made from raw milk is safely produced and consumed in many areas around the world.

| Esta pesquisa investiga o movimento agroecológico em Rio Branco do Sul/PR, como um novo movimento social, buscando analisar as trajetórias e obstáculos na construção de um paradigma ecológico para a produção e comercialização alimentar. Desde os anos 1990 agricultores familiares de Rio Branco do Sul têm convertido suas unidades de produção para bases ecológicas como uma estratégia de reconstrução de suas relações com a natureza. Através de entrevistas semiestruturadas e dados acumulados pelos programas de Pós-graduação em Sociologia da UFPR e Doutorado em Meio Ambiente e Desenvolvimento da UFPR, verifica-se que as razões para a conversão à agricultura ecológica estão relacionadas às preocupações com a saúde da família em primeiro lugar, mas também com a... |

| De landbouw is door het na-oorlogse moderniseringsproces steeds verder ontkoppeld van de ecologische en sociale omgeving. De kwaliteit van het cultuurlandschap, dat immers is ontstaan in een wisselwerking tussen landbouwactiviteiten en natuurlijke gebiedskenmerken, is hierdoor sterk afgenomen. Tegelijkertijd is er vanwege de toenemende ruimtevraag voor andere functies behoefte aan een multifunctioneel platteland. Onze doelstelling is zichtbaar te maken hoe verschillende typen landbouw, waaronder de biologische landbouw, (kunnen) bijdragen aan de landschapskwaliteit en multifunctionaliteit van een streek. Met het begrip leesbaarheid is het mogelijk de bijdrage van landbouwbedrijven aan de landschapskwaliteit van de streek te bepalen. De leesbaarheid van... |

| In Europe, similarly to propagation material for conventional agriculture, the grapevine organic propagating material must have a certified sanitary status and comply with the requirements of the legislation (EU Reg. 193/68 and Italian D.P.R. N°1164). In organic farming considering the low availability of means to control virus and virus-like disease vector populations and potential virus sources (herbaceous species) it is important to evaluate and prevent all risks of vine reinfection. In three potential suitable fields the following risks have been analysed and evaluated: a) presence of transmissible viruses in spontaneous herbaceous flora (by ELISA and biological assays) and in the surrounding vineyards (by ELISA); b) presence of virus and phytoplasma... |

| Over the last years, organic agriculture has attracted much attention in the Mediterranean countries for both environmental reasons and market opportunities. Composts and derived materials match closely with the organic farming approaches because of the beneficial effects on soil properties and functions, on plant nutrition and pathogens suppression and on several environmental concerns. This study compares the effects of compost tea (applied through fertigation and foliar application) on soil fertility, plant growth and food quality of two varieties of tomatoes (Vespro and Multiplo) in comparison with the effect of compost and commercial biofertilizer (Guanito) according to a split plot design. Compost, compost tea and Guanito revealed significant... |

| Investigations were carried out for the biological control of Phytophthora nicotianae (citrus root rot) on two citrus rootstocks (Sour orange and Troyer citrange) transplanted in organic and conventional substrates, treated with the semi-commercial product Clonotri (Trichoderma harzianum and Clonostachys rosea) and Metalaxyl-M as a chemical control. Clonotri was more efficient than the chemical treatment increasing plant high and weight. Organic products (Chitosan, Quillaia, Equiseto and Clonotri) were evaluated for seed treatments as alternative to copper, for the control of P. nicotianae and Rhizoctonia solani during seed storage and germination. Clonotri (10, 20 ml/l), Chitosan (10 g/l) and Equiseto (20g/l) showed the best results. A standardization of... |

| The use of alternative treatment types within conventional and organic cattle farming is increasing. Within the organic milk farming industry in Denmark, attention towards alternative treatment has particularly intensified after the EU regulation No. 1804/1999 has been implemented. According to this regulation, diseases should preferably be treated with alternative medicine (phyto-therapeutic products or homoeopathic solutions) when these are effective in the treatment of the species and condition in question. The 2 alternative medicines mentioned in the legislation comprise a heterogeneous group of treatments in terms of mechanism of effect. While there is information relating to the mechanism of effect of phyto-therapeutic products, in that the effect of... |

| In this study the effects on the performance of heifers reared in a suckling system (suckled heifers) compared to heifers reared in a bucket system (bucket heifers) were investigated. Heifers are young dairy cows that started first lactation. Focus was on the following parameters: age and live weight at first calving, milk production, and mastitis incidence. Also, attention was given to Paratuberculosis since suckling systems might increase the risks on its occurrence. |

| Die Kirschessigfliege hat sich in Deutschland und anderen europäischen Ländern etabliert. Auch wenn ihr Auftreten nicht in jedem Jahr einen wirtschaftlichen Totalschaden verursachen wird, gilt es trotzdem Maßnahmen zu ergreifen. Im Rahmen der Bachelorarbeit „Maßnahmen zur Bekämpfung von Drosophila suzukii im biologischen Weinbau“ wurden einerseits in einer Literaturstudie die vorbeugenden kulturtechnischen Maßnahmen zur Befallsprävention analysiert. Im Rahmen einer guten fachlichen Praxis sollten diese auf die mögliche Anwendung von den ProduzentInnen geprüft und auf individuelle Gegebenheiten in den jeweiligen Weinbaubetrieben angepasst werden. Andererseits wurde im Rahmen der Arbeit die Wirksamkeit von 28 Pflanzenschutzmitteln, die für den ökologischen... |
