91	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 balance Norlén, 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. diet vegan vegetarian biological farming permaculture conservation agriculture holistic management natural farming soil organic matter carbon sequestration crop rotation season extension yield statistics self-sufficiency greenhouse energy balance air/water heat pump kost vegan vegetarian biologiskt jordbruk permakultur organiskt innehåll kolupptagning växtföljd säsongsförlängning skördestatistik självförsörjning växthus energibalans luft/vatten-värmepump

No. of bitstreams: 1 Flavia Blaia dAvila.pdf: 19547858 bytes, checksum: b492df89170b5f41c329295c5bc184c9 (MD5) Previous issue date: 2008-05-26 / The research is based on an analysis of the changes that are occurring in trying to adapt the limitations of the planet facing the constant demands of humanity. After an initial analysis of the problems of growth of cities and the exploitation of natural resources, there is a major historical events and documents produced in the environmental area and presentation of a number of changes in the field of architecture and urbanism. There is then an analysis on techniques to improve the environment urban or peri-urban and feel the need to incorporate principles of ecology in planning and city management. The first technical deal with water resources and urban drainage, pointing the principles proposed for sustainable management of rainwater. In addition to these proposals, there is a land of bioengineering and fitorremedia??o, which are techniques for stabilization and recovery of degraded areas, especially in water courses. Shall be analysed then the permaculture, a philosophy that is creating scenarios in human space already offering a number of practices they consider the energy cycle of human actions, aimed at reduction of waste and ecological awareness in food production and actions of everyday life. The permaculture serves as the basis for ecological communities, called "ecovilas", which house thousands of people seeking to live with another form of relationship with nature around the world. The research is finished with considerations of these approaches, relating them and suggesting lines of future study. / A pesquisa baseia-se em uma an?lise sobre as mudan?as que v?m ocorrendo na tentativa de adapta??o das limita??es do planeta frente ?s constantes exig?ncias da humanidade.

93	Starting from the ground - the transformative potential of grassroots movements towards sustainability : Imagining and practicing permaculture at Kosters Trädgårdar, Sweden Schmit, Sue January 2020 (has links) This thesis examines the transformative potential of grassroots movements for sustainability and thus asks how citizen-led initiatives can contribute the United Nation’s 2030 Agenda. In focus is the permaculture movement and its efforts to promote small-scale farming in balance with ecological systems and principles. The study draws upon an ethnographic study of the permaculture farm Kosters Trädgårdar, located on the west coast of Sweden. Through extended participant observation and four interviews with owners and workers at Kosters Trädgårdar, this thesis seeks to identify the transformative visions, practices and agents mobilized by the permaculture movement. Although permaculture has a strong ecological heritage and is closely tied to small-scale farming practices, this study identifies a shift in the meaning of the term as explained hereafter. The experiences of Kosters Trädgårdar indicate that the cultivation of social community and alternative livelihoods is an equally important aspect of the permaculture movement that holds significant transformative potential. By inviting multiple actors to participate in and learn from the farming practices, and to enjoy and socialize around ecological food, Kosters Trädgårdar is effectively building local community and spreading its visions of sustainable food production beyond the circuits of the farm. Although we should not over-estimate the upscaling potential of local experiences, this permaculture farm emerges as a site of grassroot innovation, experimentation and learning and may hereby function as a testbed for the grand transformative visions of the 2030 Agenda for Sustainable Development.

94	Performative Resistance as Ecofeminist Praxis? Johnson, Benjamin D 05 1900 (has links) Erika Cudworth's Developing Ecofeminist Theory provides a helpful foundation for a non-essentialist, properly intersectional ecofeminist account of oppression, marginalization, and domination, but her rejection of what she refers to as "postmodernism" appears to be based on a misreading of Judith Butler. I attempt to provide a synthesis of Cudworth's framework with Butler, particularly through the use of Karen Barad's agential realism, in order to provide possibility for new alliances between ecofeminism and other anti-oppressive frameworks. I then examine what it might look like to do ecofeminist praxis, given the complex view of agency, ontology, and intersectionality rendered by such a synthesis. I draw from bicycling as an example from which to extrapolate what it means to resist oppression, and then draw from the Philosophy for Children movement to consider what such resistance might look like within the classroom. This dissertation thus attempts to move from theory to practice, recognizing that "the real world" is both always at hand and also subject to performative deconstruction. environmental philosophy environmental ethics ecofeminism feminism new materialism performativity agential realism postmodernism Judith Butler Erika Cudworth Karen Barad bell hooks bicycle rhizome radical permaculture praxis resistance oppression pedagogy p4c philosophy for children philosophy with children children undergraduate teaching education real material humility dialogue listening relationality indeterminacy certainty deconstruction intersectionality solidarity
95	Cultiver la ville, semer la permaculture humaine: expérimentations de jardiniers et de plantes en sol québécois Baillargeon, Léanne 08 1900 (has links) Le terme « agriculture urbaine » renvoie à une diversité de « pratiques agricoles individuelles ou collectives qui se déroulent au sein même de la ville » (Mundler et coll., 2014). Bien que le sujet ait déjà généré beaucoup d’intérêt académique, ce mémoire vise à offrir une perspective novatrice, centrée sur les changements ontologiques qui se produisent chez les jardiniers tels que rapportés dans leurs témoignages alors qu’ils s’engagent pratiquement et affectivement avec les plantes qu’ils et elles cultivent. De cet engagement résulte la participation des jardiniers.ères à un réseau de relations multiespèces impliquant tous les insectes, animaux, champignons et microbes qui interagissent avec leurs plantes. Je décris ainsi comment les jardiniers.ères en viennent à développer des liens avec toutes ces espèces fourmillantes et à s’engager pour qu’elles prospèrent. Finalement, cet engagement les fait réévaluer comment ils désirent prendre une place comme humains dans ce collectif multiespèces et ils et elles en viennent à repenser le social sur le modèle permaculturel inspiré du jardin pour imaginer une « permaculture humaine », une nouvelle manière d’envisager le lien social et l’existence humaine et urbaine. / The term “urban agriculture” refers to a diversity of “individual and collective agricultural practices taking place within a city” (Mundler et al., 2014, free translation). This subject has been the interest of much discourse in the academic as well as the public sphere, as we hear more and more about a “greening of cities” that is coming about with increasing temperatures, drought, fresh food scarcity and loss of biodiversity in and around cities. This dissertation aims to offer a novel perspective on the subject of urban gardening, inspired by literature around ontologies and multispecies sociability. In my interviews of different urban gardeners involved in the production of food in cities around the province of Quebec, I highlight how these gardeners’ perspectives—and, more fundamentally, their world vision—become transformed as they entangle themselves in the network of multispecies living taking place in and around the garden. As their understanding of other species in the garden are transformed, so are their perspective of themselves as humans and their knowing of their place in the garden-and more generally, on our planet. Their practice of care, attention and responsibility for their other-than-human counterparts in the garden also allows them to rethink the politics of their occupation of urban space and food production more generally, as they propose we move towards a “human permaculture”.

96	The Ecological and Social Effects of Gentrification and Urbanisation in Thailand's Lower Chao Phraya Delta O'Kane, Daniel January 2022 (has links) Rapid economic development and urban expansion of the Bangkok Metropolitan Region (BMR) places pressure on biomes and communities alike. In a world suffering from the increasing effects of climate change, unchecked urbanisation comes at the expense of carbon sequestrating environments. The modernisation, concretisation and gentrification of this low-lying, deltaic, monsoonal metropolis has seen its traditional, water-based urban morphology replaced with a solid state of perception, parallel to a loss of flood mitigating infrastructure. As the metropolis’ boundaries expand into its hinterlands, agriculturally productive land is being converted to residential, commercial and industrial development and the fate of low-income urban populations and farmers lies in the hands of speculators hoping to capitalise on increasing land values. Combatting this backdrop of neoliberal urbanisation is legislative framework intended to prevent speculation, yet it results in additional ecological damage as landowners clear natural-growth forests and mangroves to meet tax-reducing criterium. The purpose of this thesis is to examine the reasons behind and consequences of under-regulated urbanisation and gentrification and the effects this has had on the vulnerable ecology and communities of the BMR. It provides lessons on how previous short sighted and poor development regulations will have enduring social and environmental consequences long into the future and how adoption of traditional morphological ways-of-life and legislative amendments can limit further damage. The legacy of neoliberal urban development resulting in gentrification and underpinned by conflicting local planning laws are analysed and supported by various theoretical materials, field studies and interviews.
