Sharing A Place-Based Indigenous Methodology And Learnings, Sandra Wooltorton, Len Collard, Pierre Horwitz, Anne Poelina, David Palmer

Nulungu Journal Articles

Building on a methodology of Cooperative Inquiry, the outcomes of five interconnected place-based learning projects from Australia are synthesised and elaborated in this paper. The methodology can facilitate the everyday living and sharing of an Earth-based consciousness: one that enriches Transformative Sustainability Education (TSE) through recognising meanings and stories in landscape, and celebrates Indigenous ways of knowing, being and doing. Indigenous-led environmental education is shown to link with one of the longest continuous environmental education systems in the world and it is contended that because of its ongoing history, environmental education carries a cultural obligation. In Australia, every landscape is …

Design Hub: Activating Community By Design, Ed Williams

Theses and Dissertations

MOTIVATION

At the turn of the century, Robert Putnam (2000, 27) wrote “...a powerful tide bore Americans into ever deeper engagement in the life of their communities, but a few decades ago that tide reversed and we were overtaken by a treacherous rip current.” Putnam is describing a loss of “social capital” throughout American society. Research suggests that many of our contemporary issues are the result of a decline in “social capital,” or “community.”

This pervasive lack of community is thought to be detrimental to “educational performance, safe neighborhoods, equitable tax collection, democratic responsiveness, everyday honesty, and even our health …

First, this collection focuses on how conflict impacts women’s lives and well-being, including rape and gendered constructions of ethnicity, race, and religion. The book’s second section looks beyond the scope of large-scale violence to examine human security in terms of environmental policy, food, water, health, and economics. …

Real-Time Evaluation Of City–University Partnerships For Sustainability And Resilience, Liliana Elizabeth Caughman, Lauren Withycombe Keeler, Fletcher Beaudoin

Institute for Sustainable Solutions Publications and Presentations

Cities face many challenges in their efforts to create more sustainable and resilient urban environments for their residents. Among these challenges is the structure of city administrations themselves. Partnerships between cities and universities are one way that cities can address some of the internal structural barriers to transformation. However, city–university partnerships do not necessarily generate transformative outcomes, and relationships between cities and universities are complicated by history, politics, and the structures the partnerships are attempting to overcome. In this paper, focus groups and trial evaluations from five city–university partnerships in three countries are used to develop a formative evaluation tool …

Ethical Eating: Overcoming Alienation In The Industrial Food System By Aligning Our Practices With Our Principles, André Kushnir

Graduate Student Theses, Dissertations, & Professional Papers

This thesis arose out of a moment of discord, while an environmental philosopher was eating blackberries in the middle of a blizzard in Missoula, Montana. What follows is an attempt to bridge the gap between our principles and our practices, by asking the questions: What does ethical eating look like? Is it possible within our current industrial food system? and If not, what needs to change? Responding to the publication of the 2019 EAT-Lancet report, this essay moves beyond thinking of ethical eating as “healthy” and “sustainable” and challenges the networks of suffering and labour that we take for …

Food Policy For A Healthy, Sustainable, And Equitable Local Food System: Recommendations For Missoula, Erika Berglund

Graduate Student Theses, Dissertations, & Professional Papers

Over the last several decades, food policy councils (FPCs) have led the effort to place food on local government policy agendas. While FPCs continue to make progress in supporting local food systems, they also face institutional and organizational challenges. In recent years, a handful of cities and counties have endeavored to further food system reform with the establishment of full-time food policy staff positions. Currently, there are 19 confirmed food policy positions housed in local governments across the U.S. While there is considerable literature on FPCs, little research has been published regarding governmental food policy staff positions. This study uses …

Projecting Spatial Changes In Sugar Maple Sap Flow Regimes In A Changing Climate, Holly Crawford

Theses and Dissertations (Comprehensive)

Anthropogenic climate change presents a potential threat to maple syrup production in Canada. To mitigate risks associated with climate change, information about the biological changes that may occur in a warming climate are necessary. This project studied one component- sap flow- that in part determines the economic viability of maple syrup production. A temperature-based sap flow model was used to project the start of the sap flow season in southern Ontario, and GIS applications were used to aggregate the results. The start of the sap flow season was projected for early, mid, and late-century periods under two climate change scenarios, …

Seeking A Path To Wellness And Flourishing: Exploring Ecological Citizenship, Systems Thinking, And Environmental Governance In Southwest Yukon, Amanda Solmes

Theses and Dissertations (Comprehensive)

While efforts toward environmental management (EM) have been increasing, the state of our natural world is getting worse. Numerous reports have outlined that today’s environmental problems are predominantly human-induced, yet approaches to EM often only address “environmental” rather than “human” issues. More holistic approaches are required. This thesis explores “ecological citizenship” (EC) as an alternative framework that may have the potential to address elements too often left out of top-down and reductionist approaches. Academic and case-based notions of this concept are explored, and a new definition for the term is developed. A case study, drawn from the rich results of …

Family Forest Owners Satisfaction With Timber Transactions, Jeffrey M. Lee

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forest industries in the eastern U.S. rely heavily on family forest owners to supply fiber needs for their mills. As of 2017, 79 percent of West Virginia is classified as forestland and of this roughly 86.5 percent is privately owned. With such a heavy reliance on wood from private forest lands, family forest owner satisfaction is extremely important if companies want to continue harvesting or working with these landowners in the future.

Timber transactions are complex. No two timber transactions are exactly the same. They often involve many different parties apart from the landowner. Site conditions, land cover, and landowner …

Analysis Of European Union Forest Law Enforcement, Governance, And Trade Efficacy: A Multi-Scale Perspective, Marshall Adams

Antioch University Dissertations & Theses

Since the 1992 United Nations Conference on Environment and Development (UNCED), the international community has launched several policy initiatives to address complex environmental problems, in particular illegal logging. One such initiative is the European Union (EU) Forest Law Enforcement, Governance, and Trade (FLEGT) Action Plan and its Voluntary Partnership Agreements (VPAs). The scholarship on FLEGT has overwhelmingly focused on technical and governance aspects, drawing largely from a single institutional analysis theory. However, there is scant empirical research on a range of theories to understand FLEGT efficacy from a multi-scalar governance perspective. My dissertation research contributes to a multi-scalar forest governance …

Understanding Pro-Environmental Binning Behaviour Of National Park Visitors: A Cross-Cultural Study, Kourosh Esfandiar

Theses: Doctorates and Masters

The growing importance of people’s pro-environmental behaviours (PEBs) in relation to reducing their negative impacts and/or increasing their positive impacts in natural areas has attracted considerable research interest. Visitor engagement in pro-environmental activities is one of the key elements in maintaining and improving a national park’s ecological and biological resources. These resources are often the main components of tourism products developed in nature-based destinations.

A specific concern for many national park managers is the generation of litter by visitors. A PEB to solve the problem of litter management in national parks is binning i.e. putting litter in a bin. As …
