Modeling Scenarios Of Sea-Level Rise And Human Migration: Rita Village, The Republic Of The Marshall Islands, Donna Davis Dec 2014

Modeling Scenarios Of Sea-Level Rise And Human Migration: Rita Village, The Republic Of The Marshall Islands, Donna Davis

Graduate Theses and Dissertations

This study explores the relationship between sea-level rise and human migration from Rita Village in the Republic of the Marshall Islands (RMI). As one of only four low-lying atoll countries at the forefront of risks associated with climate change, examining the extent to which sea level will rise and displace residents in the Marshall Islands is of timely importance. The approach to this research is a scenario-based, case study and it examines loss of home, human displacement and subsequent migration in Rita Village as a result of varying levels of sea level rise. The scenario-based approach is based on the …


Cultivating Communities Of Practice To Develop Local Preparedness For Climate Change, Konda Reddy Chavva Nov 2014

Cultivating Communities Of Practice To Develop Local Preparedness For Climate Change, Konda Reddy Chavva

Doctoral Dissertations

The goal of this research was to study the effectiveness of field facilitators’ (FFs) community of practice in improving ways in which FFs and farmers communicate and work together to strengthen farmers’ climate change preparedness through identifying locally suitable adaptation strategies in drought-prone districts of Andhra Pradesh State in India. In development initiatives like the one studied, FFs are often the key liaison person with each community—farmers in this case. FFs interact regularly with farmers, with whom they establish and sustain critical relationships over time. Further, they take the lead in building farmers’ capacities by contextualizing technical information that professionals …

Baleen and sperm whales, known collectively as the great whales, include the largest animals in the history of life on Earth. With high metabolic demands and large populations, whales probably had a strong influence on marine ecosystems before the advent of industrial whaling: as consumers of fish and invertebrates; as prey to other large-bodied predators; as reservoirs of and vertical and horizontal vectors for nutrients; and as detrital sources of energy and habitat in the deep sea. The decline in great whale numbers, estimated to be at least 66% and perhaps as high as 90%, has likely altered the structure …


Impacts Of Projected Climate Change Over The Lake Champlain Basin In Vermont, Justin Guilbert, Brian Beckage, Jonathan M. Winter, Radley M. Horton, Timothy Perkins, Arne Bomblies Jan 2014

Impacts Of Projected Climate Change Over The Lake Champlain Basin In Vermont, Justin Guilbert, Brian Beckage, Jonathan M. Winter, Radley M. Horton, Timothy Perkins, Arne Bomblies

College of Agriculture and Life Sciences Faculty Publications

The Lake Champlain basin is a critical ecological and socioeconomic resource of the northeastern United States and southern Quebec, Canada. While general circulation models (GCMs) provide an overview of climate change in the region, they lack the spatial and temporal resolution necessary to fully anticipate the effects of rising global temperatures associated with increasing greenhouse gas concentrations. Observed trends in precipitation and temperature were assessed across the Lake Champlain basin to bridge the gap between global climate change and local impacts. Future shifts in precipitation and temperature were evaluated as well as derived indices, including maple syrup production, days above …


Life In Hampton Roads Survey Press Release #5: Under Water? Sea Level Rise And Environmental Risks, Social Science Research Center, Old Dominion University Jan 2014

Life In Hampton Roads Survey Press Release #5: Under Water? Sea Level Rise And Environmental Risks, Social Science Research Center, Old Dominion University

Life in Hampton Roads Survey Report

This report examines regional and sub-regional measures of environmental risk perceptions from the 2014 Life In Hampton Roads survey (LIHR 2014) conducted by the Old Dominion University Social Science Research Center.


Shade Coffee: Update On A Disappearing Refuge For Biodiversity, Shalene Jha, Christopher M. Bacon, Stacy M. Philpott, V. Ernesto Méndez, Peter Läderach, Robert A. Rice Jan 2014

Shade Coffee: Update On A Disappearing Refuge For Biodiversity, Shalene Jha, Christopher M. Bacon, Stacy M. Philpott, V. Ernesto Méndez, Peter Läderach, Robert A. Rice

College of Agriculture and Life Sciences Faculty Publications

In the past three decades, coffee cultivation has gained widespread attention for its crucial role in supporting local and global biodiversity. In this synthetic Overview, we present newly gathered data that summarize how global patterns in coffee distribution and shade vegetation have changed and discuss implications for biodiversity, ecosystem services, and livelihoods. Although overall cultivated coffee area has decreased by 8% since 1990, coffee production and agricultural intensification have increased in many places and shifted globally, with production expanding in Asia while contracting in Africa. Ecosystem services such as pollination, pest control, climate regulation, and nutrient sequestration are generally greater …


From Alarm To Action: Closing The Gap Between Belief And Behavior In Response To Climate Change, Kathryn Laing Doherty Jan 2014

From Alarm To Action: Closing The Gap Between Belief And Behavior In Response To Climate Change, Kathryn Laing Doherty

Antioch University Dissertations & Theses

The degree to which the climate continues to change will largely be determined by choices made by individuals and nations regarding greenhouse gas emissions. Many Americans engage in energy conservation actions. But, the political will in the United States to adopt emissions reduction policies is unlikely to exist without public demand. Therefore, public mitigation actions of individuals (e.g., contacting elected officials in support of emissions reduction) are critical to induce legislative response. The majority of individuals who are most concerned about climate change (the “Alarmed” segment) do not engage in public mitigation actions, but some do. The purpose of this …
