Valuation Of Soil Health Ecosystem Services. Vermont Payment For Ecosystem Services Technical Research Report #5, Benjamin Timothy Dube, Alissa C. White, Taylor H. Ricketts, Heather M. Darby

UVM Extension Faculty Publications

In this report, we present estimates for ecosystem services from soil health using two approaches for four different services. One approach generates estimates based on soil-health practices, and the other approach is based on improvements in soil-health indicators. For soil- health practices, such as adopting best-management practices on annual corn, we utilize a set of off-the shelf empirical models widely used to estimate ecological functions on farm landscapes. For soil-health indicators, we make estimates by linking these tools with soil data and statistical models describing how soil-health parameters influence the interaction of soils with water and their environment. We provide …

Tile Drainage Flow Partitioning And Phosphorus Export In Vermont Usa, Ryan Ruggiero, Donald Ross, Joshua W. Faulkner

Lake Champlain Sea Grant Institute

Tile drainage (TD) has been identified as a potential non-point source of phosphorus (P) pollution and subsequent water quality issues. Three fields with TD in Vermont USA were monitored to characterize hydrology and P export. Fields were in corn silage and used minimal tillage and cover cropping practices. Preferential flow path (PFP) activity was explored by separating TD flow into flow pathway and source connectivity components using two hydrograph separation techniques, electrical conductivity end member unmixing, and hydrograph recession analysis. TD was the dominant P export pathway because of higher total discharge. Drought conditions during this study limited surface runoff, …

Stormwater Subsurface Gravel Wetlands In Vermont: Permitting, Performance, And Chloride Concerns, Watershed Consulting Associates, Llc, University Of Vermont

Lake Champlain Sea Grant Institute

Subsurface gravel wetlands (SGW) are water treatment practices that utilize a saturated bed of gravel and (sometimes) wetland vegetation to filter incoming water and remove pollutants through a combination of physical filtration, adsorption, biological uptake, and microbial transformation. Water level is controlled by an outlet structure to retain a permanent subsurface pool, providing retention of stormwater volume in addition to pollutant removal. SGW are becoming increasingly popular tools for stormwater treatment in Vermont.

A varied group of partners including academic researchers, municipal stormwater managers, and consulting designers and engineers, have identified questions around stormwater gravel wetland performance as significant in …

Emulating Agricultural Disease Management: Comparing Risk Preferences Between Industry Professionals And Online Participants Using Experimental Gaming Simulations And Paired Lottery Choice Surveys, Eric M. Clark, Scott C. Merrill, Luke Trinity, Gabriela Bucini, Nicholas Cheney, Ollin Langle-Chimal, Trisha Shrum, Christopher Koliba, Asim Zia, Julia M. Smith

College of Agriculture and Life Sciences Faculty Publications

Mitigating the spread of disease is crucial for the well-being of agricultural production systems. Implementing biosecurity disease prevention measures can be expensive, so producers must balance the costs of biosecurity investments with the expected benefits of reducing the risk of infections. To investigate the risk associated with this decision making process, we developed an online experimental game that simulates biosecurity investment allocation of a pork production facility during an outbreak. Participants are presented with several scenarios that vary the visibility of the disease status and biosecurity protection implemented at neighboring facilities. Certain rounds allowed participants to spend resources to reduce …

Benchmarking methods need to be adapted to better represent the diversity of enterprises present in Vermont’s agricultural portfolio. The integration of University Extension objectives with food systems research priorities can …

Operationalizing Embeddedness For Sustainability In Local And Regional Food Systems, Joe Ament, Daniel Tobin, Scott Merrill, Caitlin Morgan, Cheryl Morse, Tung Liu, Amy Trubek

USDA Agricultural Research Service (ARS) Center

Agricultural systems are deeply embedded in social processes and the institutions that govern them. Measuring these processes and understanding the extent of that embeddedness is critical to crafting policy for sustainable agricultural systems. The bulk of measurement in sustainability research, however, focuses on economic and environmental indicators such as farm profitability and water quality. Since policy is most often aimed at what is measured, it tends to focus on issues like price, production, and market access. And while those are important, policies aimed at social issues such as community reciprocity are often outside the scope of policy design.

The gap …

The goal is to contribute to the understanding, operationalization, and integration of metrics built on the ideals that viable, sustainable, and resilient food systems must support social, …

Literature Review And Comparative Analysis Of Existing Certification And Training Programs Applicable To Clean Water Project Operations And Maintenance, Marc Companion, Anna Hildebrand, Kristine Stepenuck

Lake Champlain Sea Grant Institute

Stormwater runoff that carries sediments and nutrients is a primary pollutant entering surface waters in the State of Vermont. Phosphorus pollution is driving cyanobacteria blooms in many of our lakes including Lake Champlain, Lake Carmi, and Lake Memphremagog, especially in the warmer months. Warmer weather patterns and an increased frequency of extreme storms are predicted with climate change. As such, there is critical need to take action on the land to minimize and treat stormwater runoff on-site.

The State adopted a Clean Water Act in 2015, which was swiftly followed by a Total Maximum Daily Load (TMDL) for Lakes Champlain …

Soaking Up Stormwater Through Education And Stewardship In The Lake Champlain Basin And Beyond, Lake Champlain Sea Grant, University Of Vermont Extension

Lake Champlain Sea Grant Institute

The health of Lake Champlain and other waterbodies in the Lake Champlain basin, which lies within portions of Vermont, New York and Quebec, are negatively impacted by nonpoint sources of pollution, including phosphorus, nitrogen, sediments, chloride, and bacteria. All of this pollution is carried to waterbodies in stormwater runoff. Thus, it is critical that everyone understand what stormwater is, and how to help clean it and reduce its volume before it enters local waterways.

Stormwater is water from rainfall and melting snow or ice that moves over the land, collecting pollutants as it makes its way to lakes, ponds, streams …

USDA Agricultural Research Service (ARS) Center

One of the greatest leverage points in fostering the transition to sustainability can be found in the realm of food systems. The COVID-19 pandemic has brought into sharp focus the critical importance of small farm resilience to the well-being of communities around the world. We explored the role of small and medium farms in promoting sustainable social-agricultural systems, and investigated how the resilience of these farms can be both measured and amplified. W e integrated concepts from the fields of food systems sustainability and resilience, agroecology, and positive deviance to identify indicators that can help measure and track farm resilience. …

Amplifying Agroecology In Vermont: Principles And Processes To Foster Food Systems Sustainability, Martha Caswell, Rebecca Maden, Nils Mccune, V. Ernesto Mendez, Gabriela Bucini, Janica Anderzen, Victor Izzo, Stephanie E. Hurley, Rachelle K. Gould, Joshua W. Faulkner, Maria A. Juncos-Gautier

USDA Agricultural Research Service (ARS) Center

Agroecology is grounded in principles that support transitions toward economic, social and ecological sustainability and proposes that real and lasting change will require a significant transformation of our agri-food systems. Evidence for agroecology’s potential continues to grow, both through word of mouth by farmers and social movements, and through recent scientific assessments of its performance. With endorsements from the Food & Agriculture Organization of the United Nations (FAO), national governments in both the global north and south, and social movements, it is developing the web of ‘thick legitimacy’ required for even broader adoption (Montenegro de Wit & Iles, 2016). “...Agroecology …

Awareness Of Climate Change’S Impacts And Motivation To Adapt Are Not Enough To Drive Action: A Look Of Puerto Rican Farmers After Hurricane Maria, Luis Alexis Rodríguez-Cruz, Meredith T. Niles

College of Agriculture and Life Sciences Faculty Publications

Understanding how perceptions around motivation, capacity, and climate change’s impacts relate to the adoption of adaptation practices in light of experiences with extreme weather events is important in assessing farmers’ adaptive capacity. However, very little of this work has occurred in islands, which may have different vulnerabilities and capacities for adaptation. Data of surveyed farmers throughout Puerto Rico after Hurricane Maria (n = 405, 87% response rate) were used in a structural equation model to explore the extent to which their adoption of agricultural practices and management strategies was driven by perceptions of motivation, vulnerability, and capacity as a function …

Water Pollution And Environmental Concerns In Anesthesiology, Marc Kostrubiak, Christine Vatovec, Lesley-Ann Dupigny-Giroux, Donna Rizzo, William Paganelli, Mitchell Tsai

Larner College of Medicine Fourth Year Advanced Integration Teaching/Scholarly Projects

Medications administered by anesthesia health care providers and subsequently excreted into the water supply system have the potential to affect ecological systems. Presently, there is a lack of literature examining which medications or metabolites enter the waste stream. Further, assessments of their potential environmental impact are often unknown or simply not considered as an externality of medical practice. Recent work examining the practice of anesthesiology has explored the solid waste stream, and the global warming potential of anesthetic gases, however the potential aquatic impacts remain unexplored. To address the potential for waterborne pollution and environmental toxicity, we extracted the total …

Climate Impacts Associated With Reduced Diet Diversity In Children Across Nineteen Countries, Meredith T. Niles, Benjamin F. Emery, Serge Wiltshire, Molly E. Brown, Brendan Fisher, Taylor H. Ricketts

College of Agriculture and Life Sciences Faculty Publications

It is widely anticipated that climate change will negatively affect both food security and diet diversity. Diet diversity is especially critical for children as it correlates with macro and micronutrient intake important for child development. Despite these anticipated links, little empirical evidence has demonstrated a relationship between diet diversity and climate change, especially across large datasets spanning multiple global regions and with more recent climate data. Here we use survey data from 19 countries and more than 107 000 children, coupled with 30 years of precipitation and temperature data, to explore the relationship of climate to child diet diversity while …

Modeling The Influence Of Public Risk Perceptions On The Adoption Of Green Stormwater Infrastructure: An Application Of Bayesian Belief Networks Versus Logistic Regressions On A Statewide Survey Of Households In Vermont, Qing Ren, Asim Zia, Donna M. Rizzo, Nancy Mathews

College of Engineering and Mathematical Sciences Faculty Publications

There is growing environmental psychology and behavior literature with mixed empirical evidence about the influence of public risk perceptions on the adoption of environmentally friendly “green behaviors”. Adoption of stormwater green infrastructure on residential properties, while costlier in the short term compared to conventional greywater infrastructure, plays an important role in the reduction of nutrient loading from non-point sources into freshwater rivers and lakes. In this study, we use Bayesian Belief Networks (BBNs) to analyze a 2015 survey dataset (sample size = 472 respondents) about the adoption of green infrastructure (GSI) in Vermont’s residential areas, most of which are located …

Land Use And Season Influence Event-Scale Nitrate And Soluble Reactive Phosphorus Exports And Export Stoichiometry From Headwater Catchments, Dustin W. Kincaid, Erin C. Seybold, E. Carol Adair, William B. Bowden, Julia N. Perdrial, Matthew C.H. Vaughan, Andrew W. Schroth

College of Arts and Sciences Faculty Publications

Catchment nutrient export, especially during high flow events, can influence ecological processes in receiving waters by altering nitrogen (N) and phosphorus (P) concentrations and relative amounts (stoichiometry). Event-scale N and P export dynamics may be significantly altered by land use/land cover (LULC) and season. Consequently, to manage water resources, it is important to understand how LULC and season interact to influence event N and P export. In situ, high-frequency spectrophotometers allowed us to continuously and concurrently monitor nitrate (NO3−) and soluble reactive P (SRP) concentrations and therefore examine event-scale NO3− and SRP export dynamics. Here we analyzed event NO3− and …
