Evaluating Stormwater Pollutant Removal Mechanisms By Bioretention In The Context Of Climate Change, Amanda Cording
Evaluating Stormwater Pollutant Removal Mechanisms By Bioretention In The Context Of Climate Change, Amanda Cording
Graduate College Dissertations and Theses
Stormwater runoff is one of the leading causes of water quality impairment in the U.S. Bioretention systems are ecologically engineered to treat stormwater pollution and offer exciting opportunities to provide local climate change resiliency by reducing peak runoff rates, and retaining/detaining storm volumes, yet implementation is outpacing our understanding of the underlying physical, biological, and chemical mechanisms involved in pollutant removal. Further, we do not know how performance will be affected by increases in precipitation, which are projected to occur in the northeastern U.S. as a result of climate change, or if these systems could act as a source or …
Vermont Agricultural Resilience In A Changing Climate: An Investigation Of Farmer Perceptions Of Climate Change, Risk, And Adaptation, Rachel E. Schattman
Vermont Agricultural Resilience In A Changing Climate: An Investigation Of Farmer Perceptions Of Climate Change, Risk, And Adaptation, Rachel E. Schattman
Graduate College Dissertations and Theses
Climate change forecasts tell of significant challenges ahead for agrifood systems at all scales, from global to highly local. Farmers are often at the forefront of these challenges. How farmers perceive climate related risks, and the actions they take to protect or adapt their lives and livelihoods are therefore a critical area of inquiry. The purpose of this dissertation is to describe how farmers in Vermont, in the Northeastern U.S., think about climate change, and how their experiences and perceptions influence engagement with adaptation or mitigation activities. To this end, my research questions included: (1) what are farmers already doing …
A Multiscale Analysis Of The Factors Controlling Nutrient Dynamics And Cyanobacteria Blooms In Lake Champlain, Peter D. F. Isles
A Multiscale Analysis Of The Factors Controlling Nutrient Dynamics And Cyanobacteria Blooms In Lake Champlain, Peter D. F. Isles
Graduate College Dissertations and Theses
Cyanobacteria blooms have increased in Lake Champlain due to excessive nutrient loading, resulting in negative impacts on the local economy and environmental health. While climate warming is expected to promote increasingly severe cyanobacteria blooms globally, predicting the impacts of complex climate changes on individual lakes is complicated by the many physical, chemical, and biological processes which mediate nutrient dynamics and cyanobacteria growth across time and space. Furthermore, processes influencing bloom development operate on a variety of temporal scales (hourly, daily, seasonal, decadal, episodic), making it difficult to identify important factors controlling bloom development using traditional methods or coarse temporal resolution …
