Shizen Nōhō: Restoring the Relationship Between Food, Nature, and People in JapanGraham, Katharine 01 January 2019 (has links)
In Japan’s postwar era, agriculture has become highly industrialized, involving heavy machinery, chemical fertilizers, and pesticides, all in the name of “progress.” Through employing such practices, humans have attempted to improve upon nature’s way of doing things, and in turn have degraded the soil’s fertility, natural ecosystems, and human health. In response to this, Shizen Nōhō has emerged in Japan as an alternative way of cultivating food. Shizen Nōhō practitioners challenge the notion that we need chemical fertilizers, pesticides, and machinery to farm successfully. Rather, they advocate for a way of growing food that functions seamlessly with natural ecosystems. This thesis explores the value of Shizen Nōhō in sustaining the natural environment, providing food for communities, and catalyzing a shift towards a more harmonious relationship with nature. By drawing on the research I conducted in central Japan, I illustrate how Shizen Nōhō offers a solution that can reunite people to the ecosystems that sustain them. Placing Shizen Nōhō within the larger context of Japan’s food system, I detail ways in which the priorities of the Japanese government and agricultural industry are not compatible with Shizen Nōhō. Therefore, if Shizen Nōhō is to be more widely adopted in Japan, communities must drive this change, rather than governmental and industrial entities. If adopted, Shizen Nōhō may serve as a vehicle for transforming the way humans interact with and view themselves in relation to nature.

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.
