| Die Vermarktung von ökologischen Lebensmitteln in Deutschland ist an die Einhaltung der entsprechenden europäischen Rahmenvorschrift geknüpft. Bis Ende 2008 war dies die Verordnung (EWG) Nr. 2092/91, deren Einhaltung durch die Öko-Lebensmittelwirtschaft in Deutschland von privaten Kontrollstellen überprüft wurde. Die privaten Kontrollstellen melden im Rahmen der gesetzlich vorgeschriebenen Überwachung Daten zu Kontroll- und Sanktionshäufigkeiten der Unternehmen an die Behörden der Länder (Überwachung auf Bundeslandebene) und an die Bundesanstalt für Landwirtschaft und Ernährung (BLE). Die BLE ist für den Transfer der Daten an die Europäische Kommission (Überwachung auf EU-Ebene) verantwortlich. Dieser Beitrag analysiert die an die Europäische Kommission... |

| The share of organically managed land is spread unevenly throughout Germany and shows pronounced regional concentrations. The spatial distribution of organic farming is assumed to be influenced by several factors. Location factors of farms are regionally different and thus may influence the spatial distribution of organic farming. Agglomeration effects and therefore spatial dependence are also considered important in determining spatial distribution. These factors with a potential influence on the spatial distribution of organic farming can be divided into four categories: natural factors, farm-structure factors, socio-economic factors and political factors. Their possible influence on the spatial distribution of organic farming is analysed by several... |

| The BÖLN-funded project assesses the current situation of the land rental market in Germany and, thereby, accounts for spatial aspects. We will draw on secondary data from the official German farm census conducted in 2010 to analyse determinants of land rental prices and their potential differences in space. Using spatial econometric methods we aim at analysing information on organic and conventional farms. To fill gaps in knowledge and experience and to ensure the practical relevance of the results, we will additionally perform explorative interviews with organic landlords and conduct a one-day workshop with experts from the organic farming sector. Based on two different empirical approaches, recommendations enhancing the competitiveness of organic... |

| Certification is a key element in marketing organic food products. Based on economic theory, this report wants to illustrate the economic reasoning for certification. The intention is to provide a description of economic concepts, which is understandable for a wider audience. We are focusing on the basic economic literature. Chapter 1 “Organic certification system” describes the current control system in the European Union. Why this is necessary, will then be explained based on a synopsis of economic literature. Of specific significance for organic certification and the CERTCOST project are the concepts of institutional economics and economics of crime. The relevant points of economic theory will be presented and discussed in chapter 2 “Theoretical... |

| A Risk Based Inspection (RBI) scheme is a planning tool used to develop the optimum plan for the execution of inspection activities. Organic certification system could benefit from the implementation of RBIs in terms of higher effectiveness, i.e. trustability, and lower transaction costs for organic operators. Data from certification bodies provide basic information about non-compliances and structural aspects of organic operators. Here we propose a methodological approach to risk analysis modelling, based on discrete choice models and Bayesian networks, both aiming at the identification of key risk factor in the organic certification process in the European Union. |

| This paper describes the Italian and German organic certification systems, including the institutions involved and the definitions of non-compliance and sanctions. Although they are both implementations of the same EU regulatory framework, these systems differ in many respects. Case study data from control bodies on non-compliance and sanctions are presented and analysed using binary choice models. This analysis shows that the occurrence of slight non-compliance and greater farm acreage are significant risk factors that explain severe non-compliance in both countries. However, to implement an efficient risk-based inspection system in the future, the data collection process must be improved and extended to examine personal attributes of farmers and... |

| Das zentrale Ziel des Forschungsprojektes ist es, Empfehlungen für eine Verbesserung der Wettbewerbsfähigkeit des ökologischen Landbaus auf dem Landpachtmarkt zu geben. Dazu werden zunächst die aktuelle Situation auf dem deutschen Landpachtmarkt analysiert und mögliche Hemmnisse für den ökologischen Landbau identifiziert. In der Studie kommen sowohl quantitative als auch qualitative Forschungsansätze zum Einsatz. Der räumlich ökonometrische Ansatz untersucht Daten der Landwirtschaftszählung 2010 und erklärt Pachtpreisunterschiede zwischen konventionellen und ökologischen Betrieben mit betriebswirtschaftlichen, natürlichen und agrarpolitischen Faktoren. Um Wissens- und Erfahrungslücken zu schließen und die Relevanz der Ergebnisse für die Praxis zu sichern,... |

| Organic food markets substantially rely on a reliable control system. To identify and isolate the effect of different factors potentially influencing the uniform implementation of organic controls, we apply a stepwise estimation of different logit models. Using control data of German farms from five important control bodies we identify, first, risk factors for non-compliance of farms, second, the impact of the control body as well as, third, the potential impact of governmental institutions which are in charge for the implementation of the control system. The results indicate a need for a more harmonized implementation of the German organic control system. |

| For a given organic farm with livestock and vegetable production in Southern Germany the economic viability of on farm produced legume seed meal as Plant Based Organic Fertiliser (PBOF) is analysed by means of a Linear Programming (LP) model in order to asses under which conditions such a fertiliser use may be profitable. Yields, labour demand and gross margins of the different farming activities are taken from data collections and adapted based on information provided by the farmer, whose specific crop rotation, labour and stable restrictions are also implemented in the LP model. Nitrogen supplies and demands of the different farming activities are drawn from data collections and information by plant scientists. Our calculations show that legume seed... |
