Soil Resilience And Arbuscular Mycorrhizal Fungi: How Fungi Can Inform Climate Change Mitigation And Adaptation In Maya Milpa Management, Courtney Mathers
Soil Resilience And Arbuscular Mycorrhizal Fungi: How Fungi Can Inform Climate Change Mitigation And Adaptation In Maya Milpa Management, Courtney Mathers
Electronic Theses and Dissertations
In Mexico’s state of Yucatán, climate change impacts like prolonged and less predictable dry season length are manifesting as threats to agricultural production and food security. Nearly two thirds of Yucatán’s population is indigenous, many of whom live in rural communities that rely on rainfed subsistence agriculture (INEGI 2015). Ensuring sufficient food production in the face of climate change relies on the quality of agricultural soils. With both mismanagement of agricultural soils and climate change posing as threats to food production in Mexico, soil management practices that increase a soil quality should be identified and promoted. The primary objective of …
Intellectual Property Rights In The Seed Industry: Barriers To Sustainable Agriculture, Elena A. Filatova
Intellectual Property Rights In The Seed Industry: Barriers To Sustainable Agriculture, Elena A. Filatova
Electronic Theses and Dissertations
The dynamics of the dominant industrial agriculture system restrict the seed industry’s innovative landscape, leading to significant negative consequences including an exacerbation of environmental risks which threaten global food security. This thesis explores how exclusionary intellectual property rights (IPRs) in the context of the seed industry constrict innovation, evolutionary pathways, and opportunities for the implementation of sustainable agriculture methods. To overcome these barriers, the application of an open source framework to seed innovation, specifically through the platform of the Open Source Seed Initiative, is evaluated as a tool for enhancing innovative capacities in seed development while broadening the accessibility and …
Climate Change And Seed Security Among Smallholder Farmers In Northern Ghana, Michael Biwalib Madin
Climate Change And Seed Security Among Smallholder Farmers In Northern Ghana, Michael Biwalib Madin
Electronic Theses and Dissertations
Smallholder agriculture is highly susceptible to climate variability and change. According to recent projections by the Intergovernmental Panel on Climate Change, this sensitivity would likely increase in the coming decades, with more erratic rainfall, prolonged dry periods, shorter growing seasons, and seed germination failures. In the African context, the mechanisms through which these ecological stressors would affect seed security are poorly understood. Drawing upon a case study of semi-arid Ghana, this study examines climate change impacts on seed security among smallholder farmers. It adopts a mixed-methods approach with intensive fieldwork in two farming communities. Conceptually, the study uses a political …
Empowering Students To Care: An Edible Garden And Farm Education Approach, Shannon C. Mcqueen
Empowering Students To Care: An Edible Garden And Farm Education Approach, Shannon C. Mcqueen
Electronic Theses and Dissertations
Through this qualitative study, I want to add to the theoretical conversation about garden and farm education in schools and offer a starting point for a conversation surrounding care and gardening/farming in schools. The purpose of this study is to understand how teachers and students demonstrate care while implementing a garden and farm curriculum. Data collection included 15 participant interviews from students, staff, administrators, and school officials from a large public school district implementing garden and farm education lessons and observations of educators, farmers, and farm interns interacting with and instructing students in a weeklong Farm Camp environment. I utilized …
Native Grass And Forb Establishment In Post-Agricultural Soil, Courtney D. Hall
Native Grass And Forb Establishment In Post-Agricultural Soil, Courtney D. Hall
Electronic Theses and Dissertations
Restoration of degraded and abandoned agricultural land in arid and semiarid climates is a global problem. The erratic patterns of precipitation these lands experience makes restoration of a plant community difficult. Application of supplemental irrigation and inoculation with arbuscular mycorrhizal fungi (AMF) are two restoration techniques that have been suggested to overcome deficits in natural precipitation. The effects and the interactions of irrigation and seeding date on the ground cover of intended species and unintended exotic species were tested in a post-agricultural restoration experiment in south-central Colorado, USA. The greatest ground cover of intended species and lowest ground cover of …
Hedging To Safety: A Political Economy Of Derivatives, Risk And Agriculture In The Developing World, Sasha Coler Breger Bush
Hedging To Safety: A Political Economy Of Derivatives, Risk And Agriculture In The Developing World, Sasha Coler Breger Bush
Electronic Theses and Dissertations
It has become common for researchers and international development institutions to recommend the use of derivative instruments to developing country farmers and policymakers as a means of insuring agricultural incomes against the threats posed by volatile global commodity prices. Despite such enthusiasm, very little research to date examines whether or not derivative instruments actually can deliver income support to agricultural producers who face commodity price risk. This dissertation evaluates these recommendations, focusing upon the potential income security benefits of hedging with futures instruments for coffee farmers in Mexico, Brazil and Uganda during the 1998-2002 coffee crisis. The three-part quantitative and …
