This study examines the productivity and resilience of agroecosystems in the Korean Peninsula. Having learned valuable lessons from a Chapman University project funded by the United States Department of Agriculture which concentrated on the semi-arid region of southwestern United States, our joint Korea—Chapman University team has applied similar methodologies to the Korean Peninsula, which is itself an interesting study case in the mid-latitude region. In particular, the Korean Peninsula has unique agricultural environments due to differences in political and socioeconomic systems between South Korea and North Korea. Specifically, North Korea has been suffering from food shortages due to natural disasters, …
Moving From Generalisations To Specificity About Mangrove –Saltmarsh Dynamics, Kerrylee Rogers, Ken W. Krauss
Moving From Generalisations To Specificity About Mangrove –Saltmarsh Dynamics, Kerrylee Rogers, Ken W. Krauss
United States Geological Survey: Staff Publications
Spatial and temporal variability in factors influencing mangrove establishment and survival affects the distribution of mangrove, particularly near their latitudinal limit, where mangrove expansion into saltmarsh is conspicuous. In this paper the spatial variability in mangrove distribution and variability in factors influencing mangrove establishment and survival during the Quaternary period are reviewed, focusing on research at latitudinal limits in Australia and mainland USA. Despite similarities in the response of mangrove to some drivers, the expression of these drivers is both spatially and temporally variable, demonstrating the need for analyses of mangrove-saltmarsh dynamics to move beyond generalizations and incorporate regional and …
Environmental Impacts Of Holiday Gift Giving Of Books And Movies, Benjamin Shaffer
Environmental Impacts Of Holiday Gift Giving Of Books And Movies, Benjamin Shaffer
DePaul Discoveries
This project examines the relationship between gift giving deadweight loss (when the cost of a gift exceeds it value to the recipient) or welfare gain (when the value of a gift to a recipient exceeds the cost of a gift), and the environmental impact of gifts. Surveys of American adults were used to determine the economic welfare losses or gains created by holiday gift giving, comparing gifts of traditional (paper) books and DVD or Blu-ray format movies. Both products showed overall welfare gains as gifts, with books averaging a larger welfare gain than movies. An ANOVA was done to determine …
The Relationship Between Carbon Emissions, Land Use Change And The Oil Palm Industry Within Southeast Asia, Savanna L. Booth
The Relationship Between Carbon Emissions, Land Use Change And The Oil Palm Industry Within Southeast Asia, Savanna L. Booth
Master's Projects and Capstones
Tropical forests store the largest amount of carbon globally by sequestering up to 2.7 Gt of carbon every year in soils and vegetation. Deforestation and the conversion of tropical peatland soil have contributed to global anthropogenic carbon dioxide emissions, as well as significantly hindering tropical ecosystems and the natural carbon sequestration potential that could potentially help mitigate atmospheric CO2 levels. Deforestation has increased rapidly since the 1970’s across Southeast Asia with oil palm contributing to 61% of deforestation between 2010 and 2015 with emissions reaching 22.1 million tons CO2-eq during that time. The conversions of tropical peatlands …
Summer Precipitation Occurrence Effect On Two Passerine Species In Thule, Greenland, Sara E. Baugh
Summer Precipitation Occurrence Effect On Two Passerine Species In Thule, Greenland, Sara E. Baugh
Celebration of Learning
Climate change is occurring at a faster rate in the Arctic than the rest of the globe, causing temperature rises at twice the rate of the global average and increased summer precipitation in the form of rain. These precipitation events are predicted to affect migratory bird species that breed throughout the Arctic. Increased occurrence of heavy rainstorms indirectly affect bird populations by impacting distribution and abundance of food supply, and directly by increasing mortality rates of juveniles. Studies conducted on bird species throughout the low Arctic regions; have shown that it is not the total precipitation of a breeding season …
Temporal Migration Shifts In The Aransas-Wood Buffalo Population Of Whooping Cranes (Grus Americana) Across North America, Joel G. Jorgensen, Mary Bomberger Brown
Temporal Migration Shifts In The Aransas-Wood Buffalo Population Of Whooping Cranes (Grus Americana) Across North America, Joel G. Jorgensen, Mary Bomberger Brown
School of Natural Resources: Faculty Publications
Birds are altering the phenology of critical life history events, including migration, in response to the effects of global climate change. Whooping Cranes (Grus americana) are one of the most critically endangered birds in the world. Their remnant population, referred to as the Aransas-Wood Buffalo Population, numbers between 300-400 individuals and migrates between the U.S. Gulf of Mexico coast and north-central Canada twice each year. Previous analyses suggested Whooping Crane migration was temporally constant in spring and fall. New analyses of observations spanning 1942-2016 show Whooping Crane migration is now occurring earlier in spring by approximately 22 days …
Understanding Community Character As A Socio-Ecological Framework To Enhance Local-Scale Adaptation: An Interdisciplinary Case Study From Rural Northwest Connecticut, Joanna Wozniak-Brown
Understanding Community Character As A Socio-Ecological Framework To Enhance Local-Scale Adaptation: An Interdisciplinary Case Study From Rural Northwest Connecticut, Joanna Wozniak-Brown
Antioch University Dissertations & Theses
Around the world, municipalities are facing new challenges, not the least of which is climate change. This is especially true for rural communities that, for a variety of reasons, will be disproportionately affected by the climatic changes and accompanying policies or programs.
This dissertation, written in manuscript-style, integrates climate change and social-ecological scholarship to address the unique character of rural communities, to communicate the complexity of rural identity through the term "rural character"; and to empower rural communities to incorporate adaptation strategies into their daily municipal operations and planning.
Specifically, this dissertation seeks to answer the following questions: What is …
