Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. Defrancis Aug 2015

Converting Croplands To Grassland: A Spatial Analysis Of The Economic Feasibility Of Soil Greenhouse Gas Mitigation In Midwest, United States, Paco C. Defrancis

Journal of Environmental and Resource Economics at Colby

The global agriculture sector is responsible for close 20% of the aggregate anthropogenic greenhouse gas (GHG) emissions emitted since the start of the industrial age. Much of these emissions are attributed to the degradation of soils due to land use change when native ecosystems were converted to agricultural fields. Soil organic carbon (SOC) has been found to decrease in temperate soils when the native (such as a forest or grassland) ecosystem is replace by croplands. The aggregate amount of organic carbon stored in soils globally is estimated be 3.3x the size of the atmospheric carbon pool. Further soil degradation ...


Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson Aug 2015

Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson

Journal of Environmental and Resource Economics at Colby

The Cafe Standards were introduced in 1975 following the Oil Embargo. The goals of this program were simple. To reduce co2 emissions in vehicles by increasing a mandatory average mpg level for car manufacturers in the United States. Recently, in 2012, the Obama Administration set new Cafe Standard requirements for car manufacturers. By 2025, all new cars on the road in the United States must average 54.5 miles per gallon, which would double the current 27 mpg average in place right now. While the intentions of this policy are to reduce co2 emissions while at the same time increasing ...


The Economics Of The Audubon Society's Sanctuary Program For Golf Courses, Dan Hyszczak Aug 2015

The Economics Of The Audubon Society's Sanctuary Program For Golf Courses, Dan Hyszczak

Journal of Environmental and Resource Economics at Colby

Millions of people play golf every year, and in 2011 Golf Courses gained $22 billion dollars in revenue. This statistic combined with golf’s inherent place in the natural environment lead to questions of value and development for golf course owners. In 1991, The Audubon Society created their Cooperative Sanctuary Program for Golf Courses (ACSP) to promote environmentally sustainable practices for golf courses and to recognize the courses that are the most environmentally in both the United States and around the world.

This paper builds off of prior research that connects golf course beauty with revenue by examining the effects ...


Preferences For Coral Reef And Fishery Management In Okinawa, Japan, Nils Carlson Aug 2015

Preferences For Coral Reef And Fishery Management In Okinawa, Japan, Nils Carlson

Journal of Environmental and Resource Economics at Colby

This study is an example of how a nonmarket valuation method – a choice experiment – can be used to influence and guide ecosystem conservation efforts. Using a choice experiment survey, this study estimates the willingness to pay (WTP) for certain hypothetical attributes of a restored and conserved coral reef in Okinawa, Japan. I find that an increase in the amount of fish available to catch in ten years as well as an increase in the extent and health of the coral reefs and the number of marine biodiversity found in the Okinawan waters after ten-years, both positively affect respondent’s utility ...

The Effects Of Land Conservation On Productivity, Robert Mccormick, Carolyn Fuwa Aug 2015

The Effects Of Land Conservation On Productivity, Robert Mccormick, Carolyn Fuwa

Journal of Environmental and Resource Economics at Colby

In this research the relationship between productivity of land conservation is analyzed using panel data of the GDP and acres conserved of all 50 U.S. states from 1998-2005. Two main theories of the conservation productivity relationship exist. The first maintains that conservation impedes productivity because it does not allow land cultivation. Conversely, the second theory maintains that land conservation has a positive effect on GDP due to the recreation and tourism it creates. Through the use of fixed effects and random effects regressions, the amount of land conserved per state is not a significant predictor of state GDP The ...


A Survey On Climate Change: How Beliefs Shape Responsibility, Connor P. Clancy, Sarah Beth Solomon Aug 2015

A Survey On Climate Change: How Beliefs Shape Responsibility, Connor P. Clancy, Sarah Beth Solomon

Journal of Environmental and Resource Economics at Colby

This paper examines the lack of awareness and feelings of personal responsibility for climate change. Previous literature suggests that while part of the United States population may be aware of climate change, they do not feel personally responsible for causing it despite feeling climate change’s effects just like everyone else. Furthermore, studies suggest that individuals also do not believe climate change will affect them now, but rather it is an issue for future generations. Using a survey, we examine which demographics and personal factors are most important in eliciting awareness for climate change, and furthermore, personal responsibility for its ...

Nsf Bets Big On David Angelini, Gerry Boyle Sep 2014

Nsf Bets Big On David Angelini, Gerry Boyle

Colby Magazine

Something has been bugging Colby geneticist David Angelini.

How, Angelini wonders, can a single species (in this case the soapberry bug) produce two distinctly different forms, one with long wings and one with short, that are not linked to sex? What is the genetic mechanism that causes the wings to develop differently?

"Why does it not overshoot the long form? he asked. "Why doesn't it undershoot the short form? Why doesn't it end up somewhere in the middle? That's an open question."

And a question that the National Science Foundation wants him to answer.


Modeling Maine’S Rockweed Harvest, Meagan Hennessey Aug 2014

Modeling Maine’S Rockweed Harvest, Meagan Hennessey

Journal of Environmental and Resource Economics at Colby

Currently, Maine is in a political struggle over the best way to manage the harvesting of Rockweed, or Ascophyllum nodosum. As the dominant macro algae along the state’s rocky intertidal zone it supports over 150 different species, meaning its loss could impact food web stability, protection of endangered species, and support of economically viable harvests. This work takes parameters found in the literature to create a Stella model, which is then manipulated to explore the relative impact of possible management strategies. It is found that a strictly accurate model is not possible to create given the current biological knowledge ...


The Hot Zone And The Cold War, Peter Nichols Jul 2014

The Hot Zone And The Cold War, Peter Nichols

Colby Magazine

It was a time when, in the nation's schools, drills for nuclear war were as frequent as fire drills- when Americans and their Soviet counterparts lived with a constant fear of imminent worldwide destruction. "You had a cultural mindset that was apocalyptic," said Robert S. Weisbrot, Christian A. Johnson Distinguished Teaching Professor of History at Colby, "that believed you could not guarantee that your wonderful suburban home and family and community...would survive ten more seconds."

"It was not simply a matter of two countries that are adversaries building up weapons," said Weisbrot. "Each saw the other as the ...
