| Der vorliegende Beitrag befasst sich mit der Überprüfung der N-Versorgung von Kartoffeln im Ökologischen Landbau mittels zweier Methoden. Zum einen wurde die für den konventionellen Landbau entwickelte Stängelsaftanalyse mittels Nitracheck-Reflektometer angewandt; zum anderen die Blattanalyse mit der Gesamtstickstoffbestimmung mittels CNS-Analysator. Die Messungen zeigen im Verlauf der Vegetationsperiode eine Abnahme sowohl der Nitratgehalte im Stängelsaft als auch der Stickstoffgehalte im Blatt. Diese Abnahme war bei den NO3-Gehalten im Stängelsaft deutlich stärker ausgeprägt als bei den Nt-Gehalten in den Blättern. Es bestehen lineare, aber sortenspezifische Zusammenhänge zwischen den NO3-Gehalten im Stängelsaft und den Nt-Gehalten in den... |

| All the main cereal crops - wheat, barley and oats, triticale, rye and spelt - can be grown organically in the UK. Until recently, the most important organic cereals were wheat and oats, with premiums paid for samples which reached milling quality. In the last year or two, more livestock farmers than arable farmers have converted to organic production so that feed grain has been in short supply, and the range of cereals grown organically has increased. New markets have also developed. Malted organic barley has been used for some time to produce beer, and now barley malt and wheat have been processed into organic whisky. |

| The spread of organic and agro-ecological farming (OF) methods in developing countries has raised a debate whether a large scale adoption of OF will increase or decrease global food security. This will however depend on a number of socio-economic factors together with the relative yield levels of OF versus conventional farming systems. Relative yields again depend on a number of agro ecological factors and the characteristics of farming systems before conversion. In areas with intensive high-input agriculture, conversion to OF will most often lead to a reduction in crop yields per ha by 20-45 % in crop rotations integrated with leguminous forage crops. In many areas with low input agricultural systems farmers have little incentive or access to use... |

| The typical Cuban farming units are large-scale cooperatives, in which farming families are more or less loosely organized. In the low lands, these cooperatives normally specialize in a few products for the market and a higher diversity of self-sufficiency crops. In the mountain areas, these cooperatives produce in diverse agroforestry systems. This is especially the case for the eastern provinces Guantanamo and Santiago. Large-scale plantations were developed by the Spanish and US colonialists, and further developed by the socialist government. After Cuban Revolution in 1959, land was distributed to more than 200’000 small farmer families through the Agrarian Reforms of 1959 and 1963, while 70 percent of the latifundio lands passed over to state control.... |

| The development of organic and with them various other forms of alternative food networks have been the subject of extensive research within the field of agro-food studies during the past 10–20 years. In that period, organic food has gained an increasing food market share and a wide number of Western countries, among them Denmark, can thus be termed mature organic markets. The maturation process, whereby the organic movement becomes an integrated part of the established food system is at first glance an obvious example of the cooptation of an alternative into the established mainstream. However, the development paths which can be termed ecological regionalisation as well as ecological postmodernisation, which have been facilitated by new means of... |

| Climate change increases the number of risks for agricultural production in arid and semiarid regions, especially in Western Africa. Smallholder farmers are particularly vulnerable to climate change risks. These risks affect their socioeconomic situation, as well as the local food sector value chain in general. Therefore, their food security is threatened if smallholder farming structures do not adapt to them. Thus, effective climate change adaptation measures for smallholders are essential and should be implemented without delay. However, success hinges on the acceptance of the promoted measures among various stakeholders. Thus, their acceptance needs to be assessed before promoting. The project “The potential of sustainable land-use systems to promote... |

| Consumers increasingly criticise food that is produced under unsatisfactory social and environmental conditions. From the very beginning, organic food production included ethical aspects and did not only care for the environment and animal welfare but also for social aspects of people affected by the organic supply chain. With the organic sector gaining additional market shares, products from organic mass production become more and more important and competition is predominantly a question of price. Ethical values going beyond the standards of the EU regulation on organic farming are no longer features of large parts of organic production. Against this background, the question arises whether there is a demand and an increased willingness to pay for... |

| In dieser Arbeit werden Befragungsdaten zum selbst eingeschätzten Kaufverhalten und zu Einstellungen, die begleitend zu einem Verbraucherpanel erhoben wurden, dem realisierten Kaufverhalten gegenüber gestellt. In Befragungen zum Kauf von Öko-Produkten neigen Käufer dazu, ihr Kaufverhalten deutlich zu überschätzen. Mit dem Vergleich von vorgeschalteten Screeningbefragungen zu Kaufhäufigkeiten und den Aufzeichnungen der realisierten Kaufakte werden Widersprüche zwischen bekundetem und tatsächlichem Kaufverhalten aufgedeckt und quantifiziert. Mittels Faktorenanalyse sind von den Teilnehmern abgegebene Einstellungsstatements verdichtet worden. Ein Vergleich der Faktorwerte von Öko-Käufern und Nicht-Käufern gibt Aufschluss darüber, in welchen... |

| Extracts of green waste compost have been shown to inhibit plant diseases. In this study, the factors influencing the mechanism of inhibition of apple scab (Venturia inaequalis) and grapevine downy mildew (Plasmopara viticola) were studied. Extracts were prepared from samples of 30 composts from commercial composting plants. Composts were extracted with 1:2 or 1:5 water for 2 or 7 days. Extracts were applied to seedling of apple and grapevine. The seedlings were artificially inoculated with V. inaequalis or P. viticola, respectively and incubated under controlled conditions. After inoculation, severity of diseases and lesion diameter were measured. The incubation time and the compost/water ratio did not influence the capacity of the extracts to protect the... |

| In diesem Beitrag werden die Ergebnisse der jährlichen Erhebung zum Biolandbau weltweit zusammengefasst. Gemäß dieser Erhebung wurden Ende 2011 37,2 Mio. Hektar landwirtschaftlicher Nutzfläche weltweit von knapp 1,8 Mio. Betrieben ökologisch bewirtschaftet. Hinzu kommen noch rund 31,6 Mio. Hektar Wildsammlungsflächen. Im Vergleich zu 2010 hat die biologisch bewirtschaftete Landwirtschaftsfläche um rund eine Mio. Hektar oder 3 % zugenommen. |

| Agriculture in China is at the onset of an Organic Revolution. From 2000 to 2006, China has moved from 45th to 2nd position in the world in number of hectares under organic management. China now has more land under organic horticulture than any other country. In the year 2005/2006, China added 12% to the world’s organic area. This accounted for 63% of the world’s annual increase in organic land, and China now has 11% of the world’s organically managed land. The antecedents to China’s Organic Revolution are examined, and reveal further growth potential in the Chinese organic sector. Longitudinal analysis of China’s food production statistics reveals explosive growth, and the consequent capacity for export has implications for food exporting nations. China... |
