| Summary of key trends and changes in 2004 The total organic flock in the EU 25 appears to have increased by between 6 and 9 per cent, depending on stock category. Greatest increases occurred for sheep in France, Italy, Spain and the UK. In the other livestock categories, increases in some countries were balanced by decline in others, leading to overall small increases (see Table 3 update1). The production area of organic cereals increased between 2003 and 2004 by approximately 6 %. Significant reduction (9%) in the cereals area seems to have occurred in Italy, Spain and Hungary, whereas the area increased in Austria, Greece and Portugal (see Table 4 update). The area for pulses appears to have declined by a further 14% in the EU 25. Reductions... |

| This paper employs a dynamic model for crimes that involve time and punishment to analyze the use of a net with illegal mesh size in a management regime where each community claims territorial use right over a fishery but has a discount rate that may differ from the social discount rate. The equilibrium stock and harvest levels are found to be much lower if the regulation is violated. Moreover, the optimal penalty for violation must be decreasing in the shadow cost of taking the risk to fish illegally, and increasing the risk of punishment increases the equilibrium stock level. |

| Nossa pesquisa parte do principio de que os produtos orgânicos são bens de qualidade diferenciada. Para se evitar o oportunismo, torna-se necessária a criação de um ambiente institucional sólido: a normatização dos parâmetros técnicos de produção e a construção de uma legislação clara. A nova legislação brasileira do setor estabeleceu que as certificadoras devem adotar os procedimentos da norma internacional ISO 65. Com isso, ABIO (Associação de Agricultores Biológicos do Estado do Rio de Janeiro), entidade que congrega a maior parte dos produtores orgânicos fluminenses, não mais conseguiria certificar seus membros a baixos preços. A manutenção da produção orgânica no estado foi ameaçada, uma vez que a maior parte dos membros da associação é de pequenos... |

| Introduction There have recently been major changes in the regulations governing the production of organic poultry products in the EU. Member States have been required to set Standards for production that meet the minimum set in Regulation (EC) 1804/99 if products, including poultry, are to be sold as organic within the EU. This has raised concerns over consistency of implementation in other Member States, and whether, directly or through derogation, this might lead to competitive advantage over the UK. MAFF were aware that France had drafted derogations in accordance with Regulation (EC) 1804/99, and intended to implement some aspects of the Regulation which were claimed to be more stringent than the basic requirements. The aim of this project... |

| Abscisic acid (ABA) plays a series of significant physiology roles in higher plants including but not limited to promote bud and seed dormancy, accelerate foliage fall, induce stomatal closure, inhibit growth and enhance resistance. Recently, it has been revealed that ABA also has an important regulator role in the growth, development and ripening of fruit. In higher plants ABA is produced from an indirect pathway from the cleavage products of carotenoids. The accumulation of endogenous ABA levels in plants is a dynamic balance controlled by the processes of biosynthesis and catabolism, through the regulation of key ABA biosynthetic gene and enzyme activities. It has been hypothesized that ABA levels could be part of the signal that trigger fruit ripening,... |

| In opdracht van de Vlaamse overheid heeft het Louis Bolk Instituut, samen met het Instituut voor landbouw- en visserijonderzoek (ILVO), een studie uitgevoerd naar de bedrijfseconomische gevolgen van de omschakeling van gangbare naar biologische landbouw. Aanleiding voor de studie waren een mogelijke herziening van de hoogte van de overheidssubsidie die biologische landbouwers in Vlaanderen hiervoor ontvangen en het geringe aantal omschakelende agrariërs. Conclusie van de studie is dat voor veel bedrijven omschakeling naar biologische landbouw een rendabel alternatief kan vormen. De studie bevestigt tevens een aantal fundamentele kwetsbaarheden en obstakels. Transitiekosten (het vergaren van nieuwe kennis en marktcontacten, de afzet van de producten en... |

| Resources for the Future (RFF), in conjunction with the U.S. Environmental Protection Agency, the Society for Risk Analysis, and the Electric Power Research Institute, held a workshop Sept. 18-20, 2000, at the RFF Conference Center in Washington, DC. The intent was to discuss how Bayesian approaches could be useful in improving techniques for estimating exposure-response functions. Ten distinguished scholars from a range of fields (medical biostatistics, decision sciences, environmental engineering, and toxicology) served as faculty. Approximately 80 people attended the workshop. Bayesian methods have been applied to a variety of problems in biomedical research and environmental risk analysis, including design of clinical trials, estimation of exposures to... |

| Face au constat alarmant de l’état actuel des masses d’eau et aux objectifs de résultats fixés par la Directive Cadre sur l’Eau, les gestionnaires de l’eau sont contraints de mettre en place des mesures préventives, en développant des plans d’actions agricoles sur leurs aires d’alimentation de captage. Au vue de l’orientation prise par les institutions françaises, l’agriculture biologique apparait comme l’un des moyens pouvant être employé sur cette problématique. Le programme Agriculture Biologique et Aires d’Alimentation de Captage (ABAAC), piloté par l’ISARA-Lyon s’inscrit dans ce contexte à travers l’étude des enjeux et des perspectives d’un tel axe de développement. S’intéressant à l’émergence d’une nouvelle catégorie de projet visant à développer... |

| Widespread concern over transmission capacity requires theoretical support to infer inadequacy from observed trends indicating reductions in the ratio of transmission to generation capacity over time. If integrated utilities had been regulated with allowed returns exceeding capital costs, transmission generation ratios would have been excessive, and observed trends might be a correction. However, numerous commentators claim that post-restructuring transmission rates have been too low, with NIMBY also discouraging investment. We model the possibility that inadequate separation between generation and transmission may result in reduced investment, in order to preserve incumbent market power in generation. However, consideration of transmission price caps and... |

| Derzeit wird in allen Bereichen der konventionellen Lebens- und Futtermittelherstellung Vitamin B2 als GVO-Derivat, welches im Fermenter mit Hilfe von gentechnisch verändertem Bacillus subtilis hergestellt wird, eingesetzt. Die Produktionen unter Biolabels bilden hier eine Ausnahme. Im Herbst 2007 wurde von Seiten der Hersteller von Biofuttermitteln eine europaweite Mangelsituation bei der Versorgung von synthetischem Vitamin B2 gemeldet. Es wurde der Wunsch geäussert, die Bio Suisse solle beim BLW eine Ausnahmebewilligung für Vitamin B2 aus Prozessen mit GVO beantragen. Im September 07 entschied der Bio Suisse Vorstand aber, dass keine GVO Derivate im Biolandbau eingesetzt werden dürfen. In der neuen EU Bioverordnung 834/07 fällt Vitamin B2 unter die... |

| Today in conventional food and feed production added vitamin B2 is produced almost exclusively from a GMO,1 namely the genetically modified Bacillus subtilis. Vitamin B2 applied in certified organic food and feed productions is an exception, as it is still synthesized conventionally. In fall 2007 and also recently, there has been a lack of non-GMO derived vitamin B2 on the European market, which has caused temporary supply problems for organic producers. This event triggered the political will to conduct new research in order to find alternative solutions for the substitution of synthetic vitamin B2 in organic agriculture. |
