Barriers And Opportunities To Electric Vehicle Development In Nepal, Allyson Krupa Oct 2019

Barriers And Opportunities To Electric Vehicle Development In Nepal, Allyson Krupa

Independent Study Project (ISP) Collection

As the global carbon dioxide level reaches its highest point in human history (407.4 parts per million), energy systems must transition from fossil fuel to renewable-powered sources. Since the transportation sector contributes nearly one-third of global greenhouse gas (GHG) emissions, electric mobility offers a significant opportunity to reduce GHG emissions. Globally, there has been a rise in demand for electric vehicles. In Nepal, a clean energy transition within the context of rising urbanization and air pollution is imperative for quality of life, socio-economic development, and broadly climate change mitigation/adaptation. Furthermore, Nepal’s vast hydropower potential may increase energy independence and provide …

Independent Study Project (ISP) Collection

Sea turtles play a critical role in marine ecosystems all over the world, including the Caribbean Sea. However, many sea turtle species are under threat due to anthropogenic impacts, such as habitat destruction and fisheries bycatch. This has caused significant declines in sea turtle populations around the world, which in turn has impacted marine ecosystems where sea turtles play critical roles in proper ecosystem functioning. A crucial part of the sea turtle life cycle that has been threatened by anthropogenic factors is nesting. Sea turtles rely on unspoiled beaches with particular physical characteristics for laying their eggs. One of the …

Avian Upsloping In The Tropics: Myioborus Miniatus And Myioborus Torquatus Abundance In Different Altitudinal Ranges In Boquete, Chiriquí, Panama, Julie Yoon

Independent Study Project (ISP) Collection

Direct and indirect effects of warming global temperatures due to climate change are known to cause upwards shifts of the altitudinal ranges of some avian species. Most susceptible to this trend and at risk of riding the “escalator to extinction” are endemic species in tropical montane cloud forests, such as Myioborus torquatus. There are abiotic factors, like temperature, and biotic interactions, such as the presence of its altitudinal neighbor Myioborus miniatus, that limit the altitudinal range of this bird species in the Neotropics. This study measured abundance of M. miniatus and M. torquatus populations at different altitudinal ranges by point …

“In Principle” Versus “In Reality”: Assessing The Potential Of Adaptive Urban Governance Toward Urban Flooding In Ho Chi Minh City’S District 7, Cindy Pham Nguyen

Independent Study Project (ISP) Collection

Flooding has become the new normal in Ho Chi Minh City (HCMC). During the rainy season, many areas of the city experience severe inundation that seriously impacts infrastructure, traffic, and economic transactions. As the effects of climate change unpredictably and rapidly manifest in Southern Vietnam, the frequency and impact of urban floods are projected to increase. In addition, within the last few decades, HCMC has rapidly developed and urbanized, transforming itself into the economic center of Southern Vietnam. However, previous studies and international experts have determined that rapid, poor development may be exacerbating urban flood issues.

In recent years, city …

Iceland's Migratory Birds In Changing Environmental Conditions: An Interactive Synthesis, Frances J. Duncan Apr 2019

Iceland's Migratory Birds In Changing Environmental Conditions: An Interactive Synthesis, Frances J. Duncan

Independent Study Project (ISP) Collection

Human-driven changes to environmental conditions alter the habitats, behaviors, and migration patterns of migratory species. Changes in temperature, vegetation, and precipitation are just some of the factors contributing to shifts in phenology, demography, and distribution of migratory birds. These changes are driven by anthropogenic climate change and amplified by human land-use change, and are especially intense at high latitudes. This project creatively communicates the effects of environmental changes on three species of migratory birds in Iceland—the northern wheatear, the Greenland white-fronted goose, and the black-tailed godwit—using principles of storytelling and game design. The resulting interactive product is a game that …


Eating Some Invasive Species Could Help To Mitigate The Impacts Of Climate Change-Related Invasions, And May Increase Future Food Security, Jesse Bull Saffeir Apr 2019

Eating Some Invasive Species Could Help To Mitigate The Impacts Of Climate Change-Related Invasions, And May Increase Future Food Security, Jesse Bull Saffeir

Independent Study Project (ISP) Collection

Climate change is predicted to increase the spread and abundance of invasive species and to erode global food security. I hypothesized that by incorporating edible invasive species into local food sheds, these two problems could help to mitigate each other. I set out to answer two questions: could eating invasive species reduce their spread and abundance? And could eating invasive species minimize the impacts of climate-change related food shocks? To answer these questions, I surveyed the existing literature on human consumption of invasive species, created a list of criteria that make an invasive species suitable for management through human consumption, …

Correlations Between Reef Health And Vertical Zonation On Ushongo Village Reef And Fungu Zinga Reef, Daniel Gates Oct 2018

Correlations Between Reef Health And Vertical Zonation On Ushongo Village Reef And Fungu Zinga Reef, Daniel Gates

Independent Study Project (ISP) Collection

While the existence of vertical zonation on coral reefs is well-known, the driving mechanisms and the influence each has is not clear. This study seeks to investigate the influence of reef health on vertical zonation. Reef health is used as a potential factor since it is essentially a broad description of reef diversity. Therefore, a healthy reef which is very diverse is likely to have more and different interspecies interactions than an unhealthy one. This project investigates whether these altered interactions results in different depth distributions of various coral types, categorized broadly by colony shape. Reef health did not seem …

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 …


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

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%), …
