Ground Warming Leads To Changes In Carbon Cycling In Northern Fen Peatlands: Implications For Carbon Storage, Ericka James

Electronic Thesis and Dissertation Repository

Northern peatlands store one third of the world’s soil carbon (C), as they remove more C from the atmosphere via photosynthesis than they release to the atmosphere through ecosystem respiration and methane (CH₄) production. Climate change threatens this function by stimulating C release from peatland stores as peat temperatures warm and soil moisture is reduced. Ground heating of +4 °C above ambient peat temperatures was initiated in a Sphagnum moss-dominated, nutrient poor fen and a Carex sedge-dominated, intermediate nutrient fen. Over one growing season, Carex fen heated plots had increases in photosynthesis (+23%), ecosystem respiration (+22%), and CH …

Essays On Climate Change-Related Extreme Events, Alvin E. Harris

Dissertations

There are increasing and urgent calls for global economies to join in the fight against the impacts of climate change (World Bank, 2020). With reports such as the World Bank (2020) of climate change costing billions of dollars in losses for economies, the purpose of my dissertation is to examine the effects of climate change-related extreme events and their potential economic effects in three areas: agriculture, migration, and the labor market.

My first essay focuses on the factors that influence farmers’ perception of risk and adaptive strategies against the effects of climate change-related extreme events. I examine whether farmers’ social …

Climate Change Adaptation In Highland Ecuador: Intersections Of Gender, Geography, And Knowledge In Farming Communities, Dinka Natali Caceres Arteaga

Latin American Studies ETDs

This dissertation uses a feminist political ecology perspective to explore the socioeconomic impacts of climate change in Ecuador, especially but not limited to the agriculture sector. It is based on the use of mixed methods that allowed the participation and validation of the local population, surpassing their role as beneficiaries to co-authors of this research.

The significance of this study relies on the position the local population holds in the fields of human geography, under a community local-planning perspective, as they attempted to collaborate in the process of adaptation to climate change by presenting analysis and calculation of an index …

Electric Grid Decarbonization Pathways: Landscape Impacts, Policy Interactions, And The Need For Cooperation, Austin Wesley Thomas

Graduate College Dissertations and Theses

Climate change has motivated governments around the world to ratify aggressive greenhouse gas emissions reduction targets. Meeting these targets will require improved energy efficiency, behavior changes, and energy system decarbonization. Many climate change and energy policy targets imply the deployment of large amounts of low carbon, renewable energy resources like wind turbines and solar photovoltaic (PV) panels but do not specify how these resources will be sited on the landscape. The relationships between weather conditions, terrain, land cover, existing electric grid infrastructure, and electricity consumers will govern how these wind and solar PV infrastructure configurations develop and how quickly they …
