Biodynamic Agriculture: A Valuable Alternative to the Industrial Farming System

Olsen, Eden K 17 May 2014 (has links)
Since the Scientific and Industrial revolutions, advancing technologies and cutting-edge science have enabled our society to continually promote a growing global economy. Industrial growth has increasingly become a top priority for most governments, notably in the agricultural realm. The advances towards agricultural industrialization began in the 17th century and escalated during the Green Revolution, which examined the possibility of using synthetic fertilizers and mechanization in farming to decrease labor and improve yields. Although seen as economically beneficial, the shift from an agrarian lifestyle to industrial farming has created an ecological, economic, and ideological crisis to our modern world. This paper aims to examine the problems associated with agricultural industrialization and investigate whether biodynamic agriculture effectively provides a solution to the problems inherent in both conventional and industrial organic agricultural methodology.

Development of sustainability within a university curriculum

Smith, Eugene Arlington 08 April 2009 (has links)
There are currently many complex issues facing human society. There are a range of well-documented environmental problems that stem from past and current methods of human development. Declining ecosystems and species extinctions aside, many humans suffer and struggle within this mounting tide of environmental hardships as well as continuing struggles with access to education and equality within society. A large portion of these struggles arise from the disparity in wealth and the seemingly oppressive nature of economic systems for the 'have-nots' of the world. This quick overview of environmental, social, and economic conditions shows the interdependencies of the three aspects of sustainability or sustainable development. As there are calls to action from the scientific community, government, and society to address these issues of sustainable development, there are a number of voices calling for general changes within the various levels of the education system and more specifically with connecting students to the subject of sustainability. This thesis makes the argument that the most effective step in addressing both these issues is an introductory course on sustainability. Although the issues of sustainability and education are framed under different context, they both can be reduced to the concept of more holistic thinkers in society and in the classroom. A review of more discipline-specific courses incorporating sustainability, faculty surveys, and alternative learning and teaching methods strengthened the course design process. The end result is an upper level undergraduate course that uses the topics of food, water, and energy to bring a new level of understanding to the student on sustainability and holistic thinking.

Towards an Ecologically Sustainable Catholic Primary School

Hindmarsh, Patricia, res.cand@acu.edu.au January 2008 (has links)
The research intention is to identify the characteristics of an ecologically sustainable contemporary Catholic primary school and the conditions that support the development of such a school community. The literature review showed there is a clear mandate from the Catholic Church to consider ecological conversion as integral to its evangelising mission, a mission that is at the heart of Catholic education, including the school. An extensive body of educational literature, including philosophy of education and curriculum frameworks, identified environmental awareness and responsibility as mandatory outcomes for all students. The literature study defined and described ecological conversion, sustainable education, environmental education and related conceptual understandings. The literature study also provided examples of strategies to guide the strategic implementation of these understandings within the total learning program of a school. From examples found in the literature, a framework, Steps in Becoming an Environmentally Active Catholic Primary School, incorporating the specifically Catholic religious dimension, was developed by the researcher to provide benchmarks and indicators against which a school’s progress in journeying towards ecological sustainability could be evaluated. This qualitative, constructionist study incorporated some elements of Grounded Theory in gathering and analysing data from within two Australian Catholic primary case study schools recognised for their commitment and good practice in sustainable education. From the analysis of the data gathered through interviews, focus groups and participant observation, the distinctive characteristics of the two schools were identified and their stage of development evaluated against the framework Steps in Becoming an Environmentally Active Catholic Primary School. In addition, the factors that had supported school development and the factors that were barriers to that development were named. From the study, conclusions about the nature of an ecologically sustainable Catholic primary school were drawn and recommendations made about how best to support the development of such a school.

Disasters as Opportunities for Change Towards Sustainability

January 2016 (has links)
abstract: Scholars have highlighted the role of disturbance and crisis, including disasters, in enabling systemic change towards sustainability. However, there are relatively few empirical studies on how individuals and organizations are able to utilize disasters as opportunities for change towards sustainability. This dissertation addresses three questions applied to two case studies: First, what changes were pursued in the aftermath of disasters, and to what extent did these changes contribute to sustainability? Second, how were people (and their organizations) able to pursue change towards sustainability? Third, what can be learned about seeing and seizing opportunities for change towards sustainability in disaster contexts and about sustaining those introduced changes over time? The research entailed the creation of a theoretical framework, synthesizing literature from disaster studies and sustainability transition studies, to enable cross-case comparison and the appraisal of sustainability outcomes (Chapter 1). The framework was applied to two empirical case studies of post-disaster recovery: the 2004 Indian Ocean Tsunami in Aceh, Indonesia (Chapter 2), and the 2010-2012 series of earthquakes in the greater Christchurch area, New Zealand (Chapter 3). The research revealed no systemic change towards sustainability in either case, although change towards sustainability was pursued in various areas, such as housing, educating, caring, and engaging in governance. Opportunities for sustainability emerged at different points following the disaster; change processes are ongoing. The sustainability changes were supported by “Sustainability Change Agents” (SCAs): people who were able to see and seize opportunities for change towards sustainability in the midst of disaster. SCAs were characterized as individuals with various attributes, starting with an ability to perceive opportunities, catalyze others to support this risk-taking endeavor, and stay in the endurance race. The study concludes with some recommendations for interventions to inform pre-disaster sustainability planning. These avenues include a toolbox and a curricular approach that would educate and enable students as future professionals to see and seize opportunities for change towards sustainability in disaster contexts (Chapter 4). / Dissertation/Thesis / Doctoral Dissertation Sustainability 2016

Toward Sustainable Anticipatory Governance: Analyzing and Assessing Nanotechnology Innovation Processes

January 2013 (has links)
abstract: Cities around the globe struggle with socio-economic disparities, resource inefficiency, environmental contamination, and quality-of-life challenges. Technological innovation, as one prominent approach to problem solving, promises to address these challenges; yet, introducing new technologies, such as nanotechnology, into society and cities has often resulted in negative consequences. Recent research has conceptually linked anticipatory governance and sustainability science: to understand the role of technology in complex problems our societies face; to anticipate negative consequences of technological innovation; and to promote long-term oriented and responsible governance of technologies. This dissertation advances this link conceptually and empirically, focusing on nanotechnology and urban sustainability challenges. The guiding question for this dissertation research is: How can nanotechnology be innovated and governed in responsible ways and with sustainable outcomes? The dissertation: analyzes the nanotechnology innovation process from an actor- and activities-oriented perspective (Chapter 2); assesses this innovation process from a comprehensive perspective on sustainable governance (Chapter 3); constructs a small set of future scenarios to consider future implications of different nanotechnology governance models (Chapter 4); and appraises the amenability of sustainability problems to nanotechnological interventions (Chapter 5). The four studies are based on data collected through literature review, document analysis, participant observation, interviews, workshops, and walking audits, as part of process analysis, scenario construction, and technology assessment. Research was conducted in collaboration with representatives from industry, government agencies, and civic organizations. The empirical parts of the four studies focus on Metropolitan Phoenix. Findings suggest that: predefined mandates and economic goals dominate the nanotechnology innovation process; normative responsibilities identified by risk governance, sustainability-oriented governance, and anticipatory governance are infrequently considered in the nanotechnology innovation process; different governance models will have major impacts on the role and effects of nanotechnology in cities in the future; and nanotechnologies, currently, do not effectively address the root causes of urban sustainability challenges and require complementary solution approaches. This dissertation contributes to the concepts of anticipatory governance and sustainability science on how to constructively guide nanotechnological innovation in order to harvest its positive potential and safeguard against negative consequences. / Dissertation/Thesis / Ph.D. Sustainability 2013

Dimensions of Phosphorus Sustainability: Phosphorus Flows in a Rapidly Growing City and Field Tests of Potential Agricultural Prototypes

January 2020 (has links)
abstract: Phosphorus (P) is a limiting nutrient in ecosystems and is mainly used as fertilizer to grow food. The demand for P is increasing due to the need for increased food supply to support a growing population. However, P is obtained from phosphate rock, a finite resource that takes millions of years to form. These phosphate rock deposits are found in only a few countries. This uneven distribution of phosphate rock leads to a potential imbalance in socio-economic systems, generating food security pressure due to unaffordability of P fertilizer. Thus, the first P-sustainability concern is a stable supply of affordable P fertilizer for agriculture. In addition, improper management of P from field to fork leaves an open end in the global P cycle that results in widespread water pollution. This eutrophication leads to toxic algal blooms and hypoxic “dead zones”. Thus, the second P-sustainability concern involves P pollution from agriculture and cities. This thesis focuses on P flows in a city (Macau as a case study) and on potential strategies for improvements of sustainable P management in city and agriculture. Chapter 2 showed a P-substance-flow analysis for Macau from 1998-2016. Macau is a city with a unique economy build on tourism. The major P flows into Macau were from food, detergent, and sand (for land reclamation). P recovery from wastewater treatment could enhance Macau’s overall P sustainability if the recovered P could be directed towards replacing mined P used to produce food. Chapters 3 and 4 tested a combination of P sustainability management tactics including recycling P from cities and enhancing P-use efficiency (PUE) in agriculture. Algae and biosolids were used as recycled-P fertilizers, and genetically transformed lettuce was used as the a PUE-enhanced crop. This P sustainable system was compared to the conventional agricultural system using commercial fertilizer and the wild type lettuce. Chapters 3 and 4 showed that trying to combine a PUE-enhancement strategy with P recycling did not work well, although organic fertilizers like algae and biosolids may be more beneficial as part of longer-term agricultural practices. This would be a good area for future research. / Dissertation/Thesis / Doctoral Dissertation Biology 2020

Crossing a Zone of Mutual Oblivion: Sustainability and Childrearing in the Anthropocene

January 2019 (has links)
abstract: Raising future generations is a culturally diverse, universally technological human project. This research brought the everyday work of raising children into the domain of sustainability scholarship, by first proposing a model of childrearing as a globally distributed socio-technical system, and then exploring the model with participants in two nodes – an elementary and middle school, and a children’s museum. In the process, the research objective shifted towards using methods that were less academic and more relevant to childrearing agents. The focus on participatory survey data was abandoned, in favor of autoethnographic documentation of a long-term engagement with a third node of the system, a child welfare setting. This approach yielded unexpected findings that fit the proposed model, identified characteristics of a Zone of Mutual Oblivion (ZMO) that exists between childrearing and sustainability, and clarified ways in which people prioritize their own needs and responsibilities, the developmental needs of children, the potential needs and capacities of future generations, and the functional integrity of ecological systems. / Dissertation/Thesis / Doctoral Dissertation Sustainability 2019

Strategies Affecting the Sustainability of Small Businesses

Bush, Malissa A. 01 January 2016 (has links)
Small business owners bolster the emergence and growth of local communities. However, many small businesses do not survive beyond 5 years. Based on systems theory, the purpose of this multiple case study was to explore the strategies used by small business owners to develop and maintain viable and long-lasting businesses. Using a multiple case study design, semistructured interviews were conducted with 6 retail business owners in DeKalb County, Georgia who were able to develop and maintain viable and long-lasting businesses. These small business owners provided detailed information on strategies used to sustain their businesses. Semistructured interviews allowed for in-depth conversations with each participant. The use of field notes, as well as member checking of interview transcripts, facilitated the verification and triangulation of key themes. Three prominent themes emerged from the thematic analysis of data collected from the interviews: assessing capital, providing good customer service, and choosing a good location. The respondents' strategies provide guidance for small business owners hoping to stay in business for the long-term. New and existing small business owners may benefit from the study by expanding knowledge gained from successful strategies; thereby, contributing to job creation and business growth in local economies.
