Dr. Adam Daigneault Testimony To The House Committee On Small Business Subcommittee On Underserved, Agricultural, And Rural Development Hearing On “Sustainable Forestry’S Role In Climate Solutions”, Adam Daigneault
General University of Maine Publications
Adam Daigneault, University of Maine E.L. Giddings Associate Professor of Forest Policy and Economics, testified Sept. 29 before a U.S. House of Representatives Committee on Small Business Subcommittee on Underserved, Agricultural, and Rural Development, chaired by Maine Rep. Jared Golden.
A focus of the hearing was the role of sustainable forestry and how small businesses across this sector are helping to address climate change. Daigneault, whose research focuses on modelling economic impacts of environmental policy on the forestry and agricultural sectors, spoke about how we can manage U.S. forests for carbon, timber and other ecosystem services, and how we can …
The Effect Of Changing Substrate On Arctic Aquatic Invertebrates Abundance, Tom Dolman
The Effect Of Changing Substrate On Arctic Aquatic Invertebrates Abundance, Tom Dolman
Michael D. Wilson Symposium
Climate change is directly affecting tundra ecosystems in northern regions, and warming temperatures have caused discontinuous permafrost and thawing sediments across the region. This project investigates how increasing erosion and the foraging patterns of migratory snow geese may degrade habitat for aquatic invertebrates in the upper Mast River, located in Wapusk National Park, Manitoba, Canada. In the past two decades, many of the important species of aquatic invertebrates have shown declines. Declining invertebrate populations are predicted to affect aquatic ecosystems and decrease the resources available to shorebirds and waterfowl, which breed and migrate through this area.

Global warming is progressing at a faster speed than has been estimated earlier in climate forecasting, and the ocean responds rather quickly to global temperature increase. This study uses remotely sensed data that were accessed from the System for Multidisciplinary Research and Applications (NASA Giovanni) to study environmental change in the Philippines’ coast. Monthly averaged sea surface temperature series from around the Philippines indicate that the Philippines follow the global trend in ocean temperature increase and show the increase of about 0.50C within two decades. Despite the high variability in temperature, the linear regressions displayed for all seasons show an …
Assessing Chemical And Biological Recovery From Acid Rain Deposition In Montane Vermont Lakes, Sydney Diamond
Assessing Chemical And Biological Recovery From Acid Rain Deposition In Montane Vermont Lakes, Sydney Diamond
Graduate College Dissertations and Theses
Vermont’s inland lakes are changing rapidly in response to anthropogenic disturbance pressures. While changes in water chemistry are well documented across the state, the biological response of primary producer communities to these shifts remains poorly understood. This project investigated the response of phytoplankton communities to the interacting effects of recovery from acidification and climate change in high-altitude lakes. We analyzed long-term monitoring and meteorological data in four of Vermont’s acid-impaired lakes and found that as pH and acid-neutralizing capacity has increased, so have concentrations of dissolved organic carbon (DOC) in most lakes. To assess the biological response to these processes, …
Shaping Soil: Examining Relationships Between Agriculture And Climate Change, Lindsay Barbieri
Shaping Soil: Examining Relationships Between Agriculture And Climate Change, Lindsay Barbieri
Graduate College Dissertations and Theses
As the ripple-effects of a changing climate shape our planet, understanding relationships between agriculture and climate change is critical. With agricultural practices shaping soils on over a third of the earth’s land surface, the soils and lands where food is produced are integral grounds for examining these relationships. While not all humans practice agriculture in similar or damaging ways, nevertheless, dominant agricultural practices are displacing beings and ecosystems and perturbing global nutrient cycles across the planet. These entwined imbalances of dominance and nutrients result in flows of excess nitrogen, phosphorus, and carbon that are responsible for nearly three-fourths of the …
Decolonizing Food Systems Research – The Case Of Household Agricultural Food Access In Bikotiba, Togo, Katryna Maria Kibler
Decolonizing Food Systems Research – The Case Of Household Agricultural Food Access In Bikotiba, Togo, Katryna Maria Kibler
Antioch University Dissertations & Theses
Indigenous West African farmers are among the most climate change threatened globally. Food insecurity is prevalent in West Africa because ecological, social, political, and economic instabilities, and globalization worsen climate pressures. In this study, I collaborated with the community of Bikotiba (bih-CO-ti-buh), Togo, to understand their household agricultural food access, one aspect of resilience to food insecurity. I adopted a feminist approach of reflexivity, radical vulnerability, and radical empathy, combined with decolonizing principles, to argue that there could be an ethical way for well-trained Western researchers to engage Indigenous communities, if negotiated carefully. Together, Indigenous Research Assistants and I developed …
