Tile Drainage Flow Partitioning And Phosphorus Export In Vermont Usa, Ryan Ruggiero, Donald Ross, Joshua W. Faulkner Jan 2022

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 Jan 2022

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 …

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 …


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 Jan 2021

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 Jan 2021

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 …


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 Jan 2021

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 Oct 2020

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 …

College of Agriculture and Life Sciences Faculty Publications

Background: Phenology data collected recently for about 300 accessions of Vigna radiata (mungbean) is an invaluable resource for investigation of impacts of climatic factors on plant development. Results: We developed a new mathematical model that describes the dynamic control of time to flowering by daily values of maximal and minimal temperature, precipitation, day length and solar radiation. We obtained model parameters by adaptation to the available experimental data. The models were validated by cross-validation and used to demonstrate that the phenology of adaptive traits, like flowering time, is strongly predicted not only by local environmental factors but also by plant …

There is broad agreement that current food systems are not on a sustainable trajectory that will enable us to reach the Sustainable Development Goals by 2030, particularly in the face of anthropogenic climate change. Guided by a consideration of some food system reconfigurations in the past, we outline an agenda of work around four action areas: rerouting old systems into new trajectories; reducing risks; minimising the environmental footprint of food systems; and realigning the enablers of change needed to make new food systems function. Here we highlight food systems levers that, along with activities within these four action areas, may …

Behavioral research on natural resource management has revealed a number of variables that can impact collective action. This research builds upon an interactive decision game using experimental economics methods with a focus on production decisions and the corresponding impact they have on ambient water quality. Using hierarchical clustering algorithms, four primary types of behavior are identified: competitive, hypercompetitive, cooperative, and hypercooperative. The results from the experiment are used to test the following three hypotheses: (1) financial incentives increase cooperative behavior, (2) increasing the number and frequency of water quality sensors increases cooperative behavior, and (3) the spatial location of the …

First Authorship Gender Gap In The Geosciences, T. Pico, P. Bierman, K. Doyle, S. Richardson

College of Arts and Sciences Faculty Publications

Although gender parity has been reached at the graduate level in the geosciences, women remain a minority in faculty positions. First authorship of peer-reviewed scholarship is a measure of academic success and is often used to project potential in the hiring process. Given the importance of first author publications for hiring and advancement, we sought to quantify whether women are underrepresented as first authors relative to their representation in the field of geoscience. We compiled first author names across 13 leading geoscience journals from January 2013 to April 2019 (n = 35,183). Using a database of 216,286 names from 79 …

Effects Of Social Cues On Biosecurity Compliance In Livestock Facilities: Evidence From Experimental Simulations, Luke Trinity, Scott C. Merrill, Eric M. Clark, Christopher J. Koliba, Asim Zia, Gabriela Bucini, Julia M. Smith

College of Agriculture and Life Sciences Faculty Publications

Disease outbreaks in U.S. animal livestock industries have economic impacts measured in hundreds of millions of dollars per year. Biosecurity, or procedures intended to protect animals against disease, is known to be effective at reducing infection risk at facilities. Yet, to the detriment of animal health, humans do not always follow biosecurity protocols. Human behavioral factors have been shown to influence willingness to follow biosecurity protocols. Here we show how social cues may affect cooperation with a biosecurity practice. Participants were immersed in a simulated swine production facility through a graphical user interface and prompted to make a decision that …

College of Arts and Sciences Faculty Publications

Journal of Applied Ecology published by John Wiley & Sons Ltd on behalf of British Ecological Society. Protected areas are central to biodiversity conservation. For marine fish, marine protected areas (MPAs) often harbour more individuals, especially of species targeted by fisheries. But precise pathways of biodiversity change remain unclear. For example, how local-scale responses combine to affect regional biodiversity, important for managing spatial networks of MPAs, is not well known. Protection potentially influences three components of fish assemblages that determine how species accumulate with sampling effort and spatial scale: the total number of individuals, the relative abundance of species and …

College of Engineering and Mathematical Sciences Faculty Publications

Lateral carbon flux through river networks is an important and poorly understood component of the global carbon budget. This work investigates how temperature and hydrology control the production and export of dissolved organic carbon (DOC) in the Susquehanna Shale Hills Critical Zone Observatory in Pennsylvania, USA. Using field measurements of daily stream discharge, evapotranspiration, and stream DOC concentration, we calibrated the catchment-scale biogeochemical reactive transport model BioRT-Flux-PIHM (Biogeochemical Reactive Transport-Flux-Penn State Integrated Hydrologic Model, BFP), which met the satisfactory standard of a Nash-Sutcliffe efficiency (NSE) value greater than 0.5. We used the calibrated model to estimate and compare the daily …


Noncooperative Dynamics In Election Interference, David Rushing Dewhurst, Christopher M. Danforth, Peter Sheridan Dodds Feb 2020

Noncooperative Dynamics In Election Interference, David Rushing Dewhurst, Christopher M. Danforth, Peter Sheridan Dodds

College of Engineering and Mathematical Sciences Faculty Publications

Foreign power interference in domestic elections is an existential threat to societies. Manifested through myriad methods from war to words, such interference is a timely example of strategic interaction between economic and political agents. We model this interaction between rational game players as a continuous-time differential game, constructing an analytical model of this competition with a variety of payoff structures. All-or-nothing attitudes by only one player regarding the outcome of the game lead to an arms race in which both countries spend increasing amounts on interference and counterinterference operations. We then confront our model with data pertaining to the Russian …


Majority Of Rural Residents Compost Food Waste: Policy And Waste Management Implications For Rural Regions, Meredith T. Niles Jan 2020

Majority Of Rural Residents Compost Food Waste: Policy And Waste Management Implications For Rural Regions, Meredith T. Niles

College of Agriculture and Life Sciences Faculty Publications

A growing number of municipalities and states are implementing household food waste diversion efforts such as curbside compost programs, though these programs present challenges for participation and implementation. While many food waste diversion programs are occurring in densely populated regions, understanding food waste management in rural regions is less studied. This research examines the food waste perceptions and current and future food waste management behaviors of residents in Vermont, one of the most rural U.S. states, through a representative telephone survey of Vermont residents (n = 583) in 2018. The findings suggest 55% of residents support banning food waste from …


Agricultural Development Addresses Food Loss And Waste While Reducing Greenhouse Gas Emissions, Gillian L. Galford, Olivia Peña, Amanda K. Sullivan, Julie Nash, Noel Gurwick, Gillian Pirolli, Meryl Richards, Julianna White, Eva Wollenberg Jan 2020

Agricultural Development Addresses Food Loss And Waste While Reducing Greenhouse Gas Emissions, Gillian L. Galford, Olivia Peña, Amanda K. Sullivan, Julie Nash, Noel Gurwick, Gillian Pirolli, Meryl Richards, Julianna White, Eva Wollenberg

Rubenstein School of Environment and Natural Resources Faculty Publications

Food loss and waste (FLW) reduce food available for consumption and increase the environmental burden of production. Reducing FLW increases agricultural and value-chain productivity and may reduce greenhouse gas emissions associated with feeding the global population. Although studies of interventions that reduce FLW exist, almost no research systematically investigates FLW interventions across multiple value chains or countries, most likely due to challenges in collecting and synthesizing data and estimates, let alone estimating greenhouse gas emissions. Our research team investigated changes in FLW in projects supported by the United States Agency for International Development's (USAID) global hunger and food security initiative, …

Are Wolves Welcome? Hunters' Attitudes Towards Wolves In Vermont, Usa, Nelson Grima, John Brainard, Brendan Fisher

Rubenstein School of Environment and Natural Resources Faculty Publications

Published by Cambridge University Press on behalf of Fauna & Flora International. The forests of the north-east USA were once home to the Wolf Canis lupus, a species that played an important role in the ecology of this region. However, wolves were eradicated from the region more than a century ago, altering the species composition of the landscape and driving cascading changes in this ecosystem. Outdoor recreation is a major component of the economy of this region, and outdoor recreationists, including the hunting community, have a strong influence over decision-making related to policies on natural resources. Given their powerful position, …
