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 …
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 …
