Ett matsystem med biologiska jordbruksmetoder och växthusodling : Kost, jordbruk och energibalans i växthus / A food system with biological farming methods and greenhouse cultivation : Diet, farming and greenhouse energy balanceNorlén, Mikael January 2016 (has links)
The project examines the possibilities to develop a local and sustainable model for food production in Uppsala with focus on diet, farming methods and different types of greenhouse installations. With the simulation software VIP energy 3.1.1 the energy balance and temperature development of greenhouses of different materials were calculated for different operating cases. The results were also compared when the greenhouse was installed stand-alone or integrated to the wall of a small standard or passive house. With a starch based diet and biological farming methods research suggests it is possible to produce food efficiently without compromising the environment or our health. The yearly food needs for a family of four that follows the suggested diet was estimated to 4362 kg and the outdoor land required to produce it was calculated to 4676 m2 through organic yield statistics. The area could however be reduced to 2813 m2 if the only starch staple in production was potatoes. The tender growing season in a greenhouse constructed with a covering of 5 mm glass or 5-16Ar-5 mm was calculated to 85 and 148 days respectively. The energy use required for year round production of mushrooms in the respective greenhouses was calculated to 53 or 16 kWh/m2,year. Half hardy plants required 399 or 173 kWh/m2,year and tender plants 953 or 358 kWh/m2,year. When the greenhouses were connected to the wall of a small house the heating demand could be reduced by up to 22 % depending on the operating case.

Ökologischer Landbau in SüdkoreaChang, Chullee 05 January 2005 (has links)
Ökologischer Landbau hat insbesondere in den vergangenen zwanzig Jahren weltweit an Bedeutung zugenommen. Im Zusammenhang mit Ernährungssicherung, ressourcenschonender Landwirtschaft und Umweltschutz ist die Entwicklung und Förderung dieses Bewirtschaftungssystems in vielen Ländern der Erde auf der Agenda. Landwirte, Verbraucher und Politiker verbinden damit die Hoffnung, Landnutzung nachhaltiger betreiben zu können und durch die Kenntnis der naturwissenschaftlichen Zusammenhänge, den Umgang mit pflanzlichen und tierischen Organismen in der landwirtschaftlichen Produktion wesensgemäßer gestalten zu können. Gleichzeitig entsprechen sie damit der Forderung von Konsumenten nach gesunden, nicht belasteten Lebensmitteln und einer intakten Umwelt. Obwohl wir weltweit die Einführung und Etablierung des Bewirtschaftungssystems ökologischer Landbau beobachten können, ist festzustellen, dass die Gründe, Wurzeln und Erscheinungsformen in den einzelnen Ländern unterschiedlich sind. Deshalb sind länderspezifische Analysen und Bewertungen notwendige Beiträge zur Theoriebildung zum ökologischen Landbau. In diesen Kontext ist die vorliegende Arbeit zu stellen. Gegenstand der Arbeit war die Analyse des gegenwärtigen Entwicklungsstandes des ökologischen Landbaus in Südkorea in den Bereichen, wie Entwicklungsgeschichte, Konzeptionen, Institutionen, Produktion und Vermarktung sowie Zertifizierung und Förderungspolitik. In einer Fallstudie wurden ausgewählte ökologisch (Yuki)-wirtschaftende Betriebe analysiert. Es werden damit Lösungsansätze zur Weiterentwicklung des ökologischen Landbaus in Südkorea dargestellt. / Organic farming has increased in meaning world-widely in particular in the past two decades. In relation to securing food supply, resource-preserving farming and environmental protection are the development and promotion of this management system in many countries on the agenda. Organic farming made it possible that farmers, consumers and politicians hope to manage land in a sustainable way, and achieve the handling of vegetable and animal organisms in the agricultural production in a suitable way. At the same time it corresponds to the need of con-sumers for healthy, not polluted food and intact environment. Although we can observe the introduction and establishment of the management system of organic farming in many countries, it needs to specify that that the reasons, roots and manifestations of organic farming in each country are different. Therefore, individual analysis and evaluation for each country necessarily contribute to build their own theory of organic farming. This work has to be viewed in this respect. The purpose of this work is to clarify: - the basic conditions of the organic farming in South Korea, - the practical change of organic farming based on the case study of organic rice cultivation and - the ideas for developing strategy of organic farming in South Korea.
