| Deutschland belegt weltweit den ersten Platz beim Umsatz mit Produkten aus der Ökologischen Aquakultur (mehrere Millionen Euro), gefolgt von Großbritannien und der Schweiz. Anders dagegen die heimische Erzeugung in ökologischer Aquakultur, die nur ca. 3% zu weltweit 9.000 t (vor allem Öko-Lachs und –Shrimps) beiträgt. Die ökologische Aquakultur hat sich also in den letzten zehn Jahren zu einer interessanten Größe in der internationalen Fischwirtschaft entwickelt, aber deutsche Aquakulturbetriebe nehmen die Option der Öko-Zertifizierung bisher kaum wahr. Umfragen bei 76 Firmen bzw. Personen ergaben, dass kleinere bzw. extensive Teichwirtschaften in der ökologischen Aquakultur zwar ein Potential sehen, aber Hindernisse bei der Etablierung von geeigneten... |

| In agricultural systems which rely on organic sources of nitrogen (N), of which the primary source is biological N fixation (BNF), it is extremely important to use N as efficiently as possible with minimal losses to the environment. The amount of N through BNF should be maximised and the availability of the residual N after legumes should be synchronised to the subsequent plant needs in the crop rotation. Six field experiments in three locations in Finland were conducted in 1994-2006 to determine the productivity and amount of BNF in red clover-grass leys of different ages. The residual effects of the leys for subsequent cereals as well as the N leaching risk were studied by field measurements and by simulation using the CoupModel. N use efficiency (NUE)... |

| Ukrudt kan være et stort problem og reducere udbyttet af økologisk dyrket vinterhvede. Ukrudtsharvning kan skade hveden når den udføres om efteråret, og kan give utilstrækkelig effekt mod oprette ukrudtsarter med pælerod når den udføres om foråret. Forsinket såning af vinterhvede fra sidst i september til først i oktober har tidligere vist sig at kunne reducere ukrudtsmængden når der ikke udførtes ukrudtsbekæmpelse. En forsøgsrække blev gennemført med niveau af mekanisk ukrudtsbekæmpelse, såstrategi (tidlig hhv. sen såning eller falsk såbed), rækkeafstand (normal, ca. 12 cm eller stor, ca. 24 cm) og ukrudtsbekæmpelse (ubehandlet, mekanisk eller herbicid). To forsøg blev udført på marker med højt ukrudtstryk med en høj forekomst af oprette ukrudtsarter,... |

| In 1995, an experiment was planted at Wädenswil for comparing organic and integrated apple production. The overall goal of this experiment was to develop a data set which allows for an objective overall comparison of the two production concepts. Horticultural, ecological and economical traits were looked at. In practical terms, the study should particularly clarify how suitable the two systems are for producing marketable fresh fruit under Swiss conditions. The approach of an on-station comparison with a split-plot design with 3 replicate blocks and the factors “production system” (1st factor) and “variety” (2nd factor) was chosen. Ninety-four percent of Swiss apple acreage is managed according to integrated production, and 5% according to organic... |

| Organic food production is a sphere where decision making is multi-facetted and complex. This applies to producers, political decision makers and consumers alike. This paper provides an overview of the economic methods that can aid such multi criteria decision making. We first provide an outline of the many different Multi-Criteria Analysis (MCA) techniques available and their relative advantages and disadvantages. In addition, theoretical and practical problems related to the use of Cost-Benefit Analysis (CBA) and MCA respectively are briefly discussed. We then review the MCA literature on case studies on organic farming. Based on this review we provide directional markers for future research where MCA may possibly be applied and adapted in order to... |

| An increased emphasis on the viability and growth of local food systems which reduce "food miles" has promoted efforts encouraging farmers and processors to sell and distribute food products to local consumers. The elasticity of complementarity is used to predict adjustments in relative wage payments if organic farmers commit to local selling. We use comprehensive U.S. data on organic practices to show that a commitment to local sales leads to lower organic farm incomes. Policies that promote a shift to local sales would lead to decreased use of seasonal workers and higher wages for seasonal workers with smaller adjustments in the wages of year-round workers. |

| O mutualismo entre formigas e plantas consiste na proteção da árvore pela formigas contra herbívoros, que recebem em troca alimento ou local para nidificação. O objetivo desta pesquisa foi verificar a relação entre Acacia mangium Willd e formigas visitantes. O estudo foi realizado em Cáceres, MT, em 14 plantas de A. mangium escolhidas ao acaso em um sistema agroflorestal. Em cada planta foi mensurada a área foliar consumida por herbívoros através de um gabarito, em quatro folhas/planta. A agressividade das formigas em relação aos herbívoros foi medida pela observação da retirada de cupins fixados nas plantas por uma hora. A relação entre a desfolha de A. mangium e a abundância de formigas e ao tempo de retirada do cupim foi analisada através de regressão... |

| This paper aims to identify the main aspects of farmers´ motivation to farm organically and their activities relating to changes in landscape composition. Organic farmers’ perceptions of landscape elements were observed through questionnaires completed by 87 farmers in the Czech Republic. The majority of farmers (88.5%) stated that environment-friendly farming practices were the main reason to enter the organic farming system. A large number of farmers (69%) stated that they have problems with some constraining conditions and rules in agri-environmental measures. Regarding the size of farms, small farms were more willing to devote part of their farmland to landscape elements. Respondents who farmed in LFA areas and landscape protected areas mentioned more... |

| The cultivation of garlic faces several problems, which include pest attack, and the diversification of habitat through intercropping with attractive plants comes up as a method to pest management. The objective of this research was to verify the effect of the association of garlic with fodder radish on richness, abundance and diversity of arthropods under organic production system in Lavras, MG, Brazil. The treatments were composed of garlic in monoculture and garlic in association with fodder radish, in plots of 40 garlic plants, intercropped or not with two lines of fodder radish. Weekly, 25 samples were collected for a period of 10 weeks (n=250). Species accumulation curves, species richness, abundance, and diversity index were determined, and T or... |

| Around the early 1970s, there was a foreign publicity manager at a famous French weekly magazine [L’Express] who, in the course of her duties, voyaged all over the world visiting clients. This person happened also to be a friend of the Organic agriculture movement in general and of the French association Nature et Progrès in particular. Her favourite sport was hunting down the pioneers of Organic agriculture who had for decades, usually unknown to each other, been doing original work in their very different countries. Karin Mundt was this intrepid hunter; if any obscure pioneers were anywhere near her flight path, she would track them down. Over several years, contacts were made all over the world. Already in Europe, the necessity was evident, if only to... |
