Shift In Icelandic Plant Populations Due To Climate Change: Through The Lens Of Natural Dyes, Molly Pluenneke 2017 SIT Study Abroad

Shift In Icelandic Plant Populations Due To Climate Change: Through The Lens Of Natural Dyes, Molly Pluenneke

Independent Study Project (ISP) Collection

Northern residing plant species are at the highest risk for extinction due to temperature rise related to climate change (Schöb, Manuel, Choler & Veit, 2009). Climate change has also led to a northern shift in the geographic distribution of plant species (Parmesan & Yohe, 2003). This could lead to a necessary alteration in the way natural resources are utilized in arctic countries like Iceland (Lim-Camacho et al, 2017). The purpose of this study is to analyze the way in which Icelandic plant species used in natural dye practices may shift in distribution due to climate change and the potential impact …


The Role Of Young Environmental Activists In Iceland And Furthering Youth Engagement With Environmental Issues, Story Schwantes 2017 SIT Study Abroad

The Role Of Young Environmental Activists In Iceland And Furthering Youth Engagement With Environmental Issues, Story Schwantes

Independent Study Project (ISP) Collection

This paper looks at the role of youth environmental activism in Iceland and how these actors view their work in a country which has long held a reputation as one of the greenest in the world. Much of the credit for that distinction goes not to careful choices, sacrifice, or excellent stewardship but rather to its ideal geography providing massive geothermal energy which Iceland turns into electricity, a clean renewable source. So are there young environmental activists in Iceland, and if so what do they do? Short answer: yes, and they study and talk. The long answer is more complex. …

Values Mapping And Counter-Mapping In Contested Landscapes: An Olympic Peninsula (Usa) Case Study, Rebecca J. McLain, Lee Cerveny, Kelly Biedenweg, David Banis 2017 Portland State University

Values Mapping And Counter-Mapping In Contested Landscapes: An Olympic Peninsula (Usa) Case Study, Rebecca J. Mclain, Lee Cerveny, Kelly Biedenweg, David Banis

Geography Faculty Publications and Presentations

Indigenous peoples, local communities, and other groups can use counter-mapping to make land claims, identify areas of desired access, or convey cultural values that diverge from the dominant paradigm. While sometimes created independently, counter-maps also can be formulated during public participation mapping events sponsored by natural resource planning agencies. Public participation mapping elicits values, uses, and meanings of landscapes from diverse stakeholders, yet individuals and advocacy groups can use the mapping process as an opportunity to make visible strongly held values and viewpoints. We present three cases from the Olympic Peninsula in Washington State to illustrate how stakeholders intentionally used …


Agricultural Responses To Climate Change: A Study Of Adaptive Farming Methods In Kizanda Village, Bailey Smith-Helman 2017 SIT Study Abroad

Agricultural Responses To Climate Change: A Study Of Adaptive Farming Methods In Kizanda Village, Bailey Smith-Helman

Independent Study Project (ISP) Collection

Agriculture is vital to the economic and social systems in Tanzania, composing 30% of the country’s GDP as well as 80% of employment (FAO, 2014). Despite agriculture’s important role, it remains one of the most vulnerable sectors to climate change. Current trends project global average temperature to increase by 0.8-2.6 degrees Celsius, leaving farmers to face changes in rainfall, soil quality, and new pests and diseases (IPCC, 2007). Farmers will be forced to adapt to the changing climate if they are to sustain their livelihoods and the Tanzanian economy. For these reasons, it is important to understand the types of …


Ethical Business Practice, Accountability, And Quality Assurance: Primary Drivers For Sustainable Tourism Development In Iceland, Abigail Harrison 2017 SIT Study Abroad

Ethical Business Practice, Accountability, And Quality Assurance: Primary Drivers For Sustainable Tourism Development In Iceland, Abigail Harrison

Independent Study Project (ISP) Collection

The tourism industry in Iceland has grown exponentially in the last decade, causing changes to the natural landscape and drastically shifting revenue streams in the economy. This rapid growth coupled with the recent development of Iceland’s tourism industry makes it the perfect case study for how to effectively mitigate tourism influxes. This unprecedented rate of growth impels the creation of sustainability measures within this industry in order to ensure a lasting vision of Icelandic tourism in the future. Both the government and private sector have already begun to institute sustainability measures in society and in business. The primary aim of …


The Effect Of Warming On Wind Speed And Potential Wind Power In Iceland, Alexei Smith 2017 SIT Study Abroad

The Effect Of Warming On Wind Speed And Potential Wind Power In Iceland, Alexei Smith

Independent Study Project (ISP) Collection

Climate change is causing a shift in the temperature and pressure gradient between the Arctic and the Equator, with the Arctic warming at a faster rate than the Equator. This shift has the potential to alter the seasonal wind speeds in the Northern Hemisphere, which could in turn affect the wind power density potential. In this study, a wind model was created to predict future wind speeds and wind power density for 6 weather stations in Iceland. According to the model, winter wind speeds and wind power density potential will either stay the same or increase slightly (0 – 4%), …

Water Quality Characterization Of A Tailwater Recovery System Associated With Row Crop Agricultural Production, Ethan Winston Leonard 2017 Arkansas State University

Water Quality Characterization Of A Tailwater Recovery System Associated With Row Crop Agricultural Production, Ethan Winston Leonard

Student Theses and Dissertations

Water levels of the Mississippi Alluvial Aquifer are declining at a greater rate than what can be recharged. Sustainable agriculture in Arkansas will require substantive investment in water storage and possible reuse, along with consideration for potential water quality changes in associated waterways. This study characterized water quality related to production changes as they impacted post irrigation water storage and reuse. Samples were collected in 2013 and 2014 at specific locations based on water transferal and connectivity within a tailwater recovery system (TWR), and water quality comparisons were made for each year. Noticeably, nitrite was found to be lower in …


Torrefaction Kinetics Of Hemp Hurds, An Emerging Agricultural Byproduct, In A Small Retort, Tel Jensen 2017 Portland State University

Torrefaction Kinetics Of Hemp Hurds, An Emerging Agricultural Byproduct, In A Small Retort, Tel Jensen

Civil and Environmental Engineering Undergraduate Honors Theses

As knowledge concerning the consequences of unsustainable energy sources and agricultural practices grows, development of low-impact alternatives to both becomes more important. Sustainable sources of biomass offer solutions to both problems. This study characterized the reaction kinetics of torrefying an agricultural byproduct, the woody interior of hemp stems, or hurds. Torrefaction was carried out at 250 °C in small and simple retorts made of galvanized steel pipe. A first-order model most closely approximated the reaction. A sensitivity analysis was performed and the data was adjusted to correct for three potential sources of error, and regressed to find the best fit …


Offshore Wind Power: Can New Jersey Find A Place At The Table?, Jeremy Firestone 2017 University of Delaware

Offshore Wind Power: Can New Jersey Find A Place At The Table?, Jeremy Firestone

Sustainability Seminar Series

NJ enacted an offshore renewable energy certificate (OREC) law in 2010. It was thought that the OREC law would usher in a new era for New Jersey, with it enjoying clean, carbon-free renewable offshore wind energy. Offshore wind development, however, has so far been stalled in New Jersey. This presentation looks beyond past and existing conflicts with elected officials and regulators that has resulted in the OREC law effectively being sidelined to consider research that sheds light on public perceptions and de-conflicting uses with an emphasis on New Jersey, but as enlightened by broader research findings and trends.

Human Energy Capstone

Activities

Movement is very important for humans. From our earliest days, we seem eager to get up and move around. The most celebrated moments of a child’s life seem to be geared around the ability to move: the first crawl, the first walk, the first bike ride, and (every parent’s nightmare) the first driver’s license. The ability to get around is one of the most cherished abilities and freedoms. For many Americans, our ability to get around when and how we want is almost considered a sacred right. Physics textbooks, which have many chapters devoted to motion, build a great many …

Efficiency

Activities

The previous two activities in this module have shown us the importance of conservation laws. These laws provide extra “tools” that allow us to analyze certain aspects of physical systems and to be able to predict the motion of objects in the systems without using more complicated analysis. Even in situations wherein we cannot exactly solve the motion, these laws are incredibly useful. For instance, if someone shows us an incredibly complicated device that can seemingly produce electricity with no energy input whatsoever, we know not to invest money in this device, as it must be a sham since it …


First Law Of Thermodynamics, 2017 Kennesaw State University

First Law Of Thermodynamics

Activities

In last week’s activity, we calculated the motion of objects by studying the forces on them. Using Newton’s Second Law of Motion, we were able to relate the forces on an object to the acceleration it experienced. The presence of constant forces led to constant accelerations, which corresponded to linearly-increasing velocities with respect to time. Comparisons made between the velocities we measured and those calculated from a study of the forces on the objects allowed us to validate Newton’s equation F = ma. In this week’s activity, we are going to investigate almost the same experimental setup as last week, …


Newton's Second Law, 2017 Kennesaw State University

Newton's Second Law

Activities

There are two ways to study the dynamics of a system in which there is motion. One of these is to study the kinematics of the system to see if there is any acceleration. If there is an acceleration, then this implies that there is a net force on some part of the system. If there is no acceleration, then this means that either there are no forces on the system, or that the forces within the system are all balanced. The other way to study the system is from an energy standpoint. Energy can flow from potential to kinetic, …

Population Growth

Activities

When George Washington started the first Presidency of the United States of America, he was governing less than 4 million people who occupied an area of 2,300,000 square kilometers. It was an agrarian society, with 95% of the population living on farms and only 5% in cities or towns of more than 2,500. There was plenty of land, and a vast array of natural resources, just waiting to be tapped. Today, we live in a country of over 294 million people. While we are one of the major food producers in the world, it is no longer due to us …

Age Structures

Activities

One of the tools that demographers use to understand population is the age structure diagram (it is sometimes called a population pyramid, but it is not always pyramidal in shape). This diagram shows the distribution by ages of females and males within a certain population in graphic form. Figure 1 shows a diagram in which the ages and sexes for the United States population are arranged so that ages are grouped together such as 0 – 4 years, 5 – 9 years, and so on. The population of each is group is represented as a bar extending from a central …

For all of its futuristic stylings, the television show Star Trek was, like most science fiction, a commentary on the state of society at the time it was written (late 1960’s). One of the more famous episodes of that series was the one entitled The Mark of Gideon, which dealt with a planet that was so overpopulated that people did not have anywhere to sit down. At the time of the show, the Earth’s population was at about 3.5 billion, and was increasing at an incredible rate. The effects of such a large population on the environment were beginning to …

Toxic Chemicals

Activities

Humans have used chemicals for a long time. The ancient Egyptians used chemicals for dyeing, soldering and coloring metal, and making jewelry. The Industrial Revolution, which began in the middle of the 18th century, spawned the development of many new chemicals and chemical processes. Since World War II, the global chemical industry has boomed. Global production of chemicals was 1 million tons in 1930 and is now over 400 million tons. Environmental scientists study chemicals to determine if they are harmful to human health and the environment. Pretty much every chemical can harm you if you ingest too much of …
