Community Science And Coyote Stories: Capturing And Communicating Nature's Non-Material Values For Use In Decision-Making, Joshua Wright Morse

Graduate College Dissertations and Theses

The reasons and ways that nature matters underlie every part of environmental decision-making. Yet, there are disparities in how different kinds of benefits from and values about nature are represented in policy and practice. This dissertation explores how decision-makers and community members value nature broadly and also in the context of a specific human-wildlife interaction in Vermont, United States.

In my first chapter, I conduct semi-structured interviews with environmental sector practitioners in Vermont to learn about their awareness of non-material values from nature. I find that practitioners talk readily about both material and non-material ecosystem services as well as multiple …

Enhancing Ecosystem Services And Climate Resilience In Agriculture: A Transdisciplinary Approach, Alissa White

Graduate College Dissertations and Theses

A complex of social, economic and environmental factors influences agricultural management in the northeastern US. Farmers often balance goals of farm viability, environmental stewardship, and resilience to climate change, while also under public pressure to enhance the provisioning of ecosystem services from their landscapes. Changes in farm management have been identified as cost-effective ways to address both local water quality issues, and global anthropogenic influences on greenhouse gas concentrations. Individual decision-making on the part of farmers that determines the fate of ecosystem service provisioning from agroecosystems, placing increasing importance on understanding how policy, outreach and research can support farmers’ capacity …

Evaluating The Distributional Equity Of Ecosystem Services Under Land Use And Climate Change Scenarios, Jesse David Gourevitch

Graduate College Dissertations and Theses

Nature supports human well-being and sustainable development through the provision of ecosystem services (ES). While ES have been mapped, modeled, and valued with multiple methods by a wide range of disciplines, understanding the distribution of ES benefits among individuals and groups within society remains a critical gap. Addressing this gap is essential for making conservation and environmental policy-making more equitable. In this dissertation, I present four studies that evaluate the distribution of ES among demographic and socioeconomic groups under a range of land use and climate change scenarios.

In my first chapter, I project changes in the supply, demand, and …

No Farm Is An Island: Pollinators And Pollination In Agricultural Landscapes, Charles C. Nicholson

Graduate College Dissertations and Theses

Productive, resilient and sustainable agricultural systems are required to meet the immediate needs of a burgeoning human population, while avoiding ecosystem collapse. Agriculture provides food, fiber, fuels and other products for our current population of 7 billion and is still the major livelihood for 40% of people worldwide. By replacing natural habitat and employing chemical inputs, agriculture also negatively impacts biodiversity and impairs the provision of ecosystem services. This poses a challenge for agriculture as these impacted services are often those required for high yielding and high-quality crop production. Evidence is accumulating that agricultural management can safeguard biodiversity and ecosystem …

The Impact Of Ecosystem Services Knowledge On Decisions, Stephen Mark Posner

Graduate College Dissertations and Theses

The need to protect diverse biological resources from ongoing development pressures is one of today's most pressing environmental challenges. In response, "ecosystem services" has emerged as a conservation framework that links human economies and natural systems through the benefits that people receive from nature. In this dissertation, I investigate the science-policy interface of ecosystem services in order to understand the use of ecosystem service decision support tools and evaluate the pathways through which ecosystem services knowledge impacts decisions. In the first paper, I track an ecosystem service valuation project in California to evaluate how the project changes the social capacity …

Connecting Landscapes To People: Assessing The Distribution Of Ecosystem Service Flows Using The Span Approach, Gary Wayne Johnson

Graduate College Dissertations and Theses

The Service Path Attribution Network (SPAN) framework provides a novel, user-centric, connectivity-based approach to ecosystem service assessment and valuation (ESAV). Ecosystem services are delivered to users through the simulated flow of some service medium (i.e., matter, energy, or information) from the ecosystems in which it originates (sources) to the people or assets which it affects (users). Along the way, the service medium may be absorbed by intervening landscape features (sinks) or captured by rival users.

Crucially, the service medium is not itself an ecosystem service or benefit but rather an agnostic transport mechanism which establishes connectivity between sources, sinks, rival …
