Description
Development throughout the course of history has traditionally resulted in the demise of biodiversity. As humans strive to develop their daily livelihoods, it is often at the expense of nearby wildlife and the environment. Conservation non-governmental organizations (NGOs), among other actors in the global agenda, have blossomed in the past century with the realization that there is an immediate need for conservation action. Unlike government agencies, conservation NGOs have an independent, potentially more objective outlook on procedures and policies that would benefit certain regions or certain species the most. They often have national and international government support, in addition to the credibility and influencing power to sway policy decisions and participate in international agendas. The key to their success lies in the ability to balance conservation efforts with socioeconomic development efforts. One cannot occur without the other, but they must work in coordination. This study looks at the example of African Great Apes. Eight ape-focused NGOs and three unique case studies will be examined in order to describe the impact that NGOs have. Most of these NGOs have been able to build the capacity from an initial conservation agenda, to incorporating socioeconomic factors that benefit the development of local communities in addition to the apes and habitat they set out to influence. This being the case, initiatives by conservation NGOs could be the key to a sustainable future in which humans and biodiversity coexist harmoniously.

Description
As an important part of the movement for local and sustainable food in our cities, urban farming has the potential to actively involve urban dwellers in environmental, social, and economic issues of a global scale. When assessed according to a three-pillar model of sustainability, it can offer solutions to many of the major problems associated with the industrial food model that currently dominates the United States market. If implemented on a larger scale in the Phoenix metropolitan area, urban farming could improve overall environmental conditions, stimulate the local economy, and help solve food access and inequality issues. Through interviews with both amateur and established local urban farmers, this thesis attempts to identify and analyze some of the main barriers to the widespread participation in and incorporation of urban agriculture in the Phoenix Valley. Problems encountered by newcomers to the practice are compared with the experiences of more successful farmers to assess which barriers may be circumvented with proper knowledge and experience and which barriers specific to the Phoenix region may require greater structural changes.

Description
Arizona State University experienced some of its most explosive growth in the 1960s—doubling its enrollment in just seven years, expanding many programs and adding a college of law, and significantly augmenting its physical plant. This work examines the architectural and planning development of ASU in this decade and the surrounding years, coinciding with the presidency of Dr. G. Homer Durham, in various facets. Topics covered include the pedestrianization of the university campus, land acquisition and street realignment; the construction of newer and taller buildings to accommodate and expanded student population and educational program; and efforts to improve the university’s prestige through the use of modern architecture. ASU’s physical and human growth is compared to selected peer institutions. The legacy of the 1960s at ASU is also discussed within a historic preservation context.

Description
Although sustainability as a concept and a science has been around for quite some time, it has only recently come into the common vernacular of citizens around the world. While there are a number of arguments that have been and can be made about the role of sustainability in developing countries, it can be said with certainty that sustainability education, especially at the pre-university level, is commonly neglected even in countries that have sustainability initiatives elsewhere in their systems. Education is an important part of development in any country, and sustainability education is critical to raising generations who are more aware of the connections in the world around them. Informal education, or education that takes place outside of a formal classroom, can provide an especially important platform for sustainability ideas. These factors take on unique characteristics within the environment of a small island with noble sustainability goals but limited resources and an economy that includes a significant domestic goat population. After providing basic background on sustainability and the nature of the educational process within the environment of the small island-nation of Grenada, I discuss the importance of informal education and follow my path with a local non-profit in Grenada leading to the development of a locally-relevant sustainability curriculum for implementation in a K-6 school.

Description
As society's energy crisis continues to become more imminent many industries and niches are seeking a new, sustainable and renewable source of electricity production. Similar to solar, wind and tidal energy, kinetic energy has the potential to generate electricity as an extremely renewable source of energy generation. While stationary bicycles can generate small amounts of electricity, the idea behind this project was to expand energy generation into the more common weight lifting side of exercising. The method for solving this problem was to find the average amount of power generated per user on a Smith machine and determine how much power was available from an accompanying energy generator. The generator consists of three phases: a copper coil and magnet generator, a full wave bridge rectifying circuit and a rheostat. These three phases working together formed a fully functioning controllable generator. The resulting issue with the kinetic energy generator was that the system was too inefficient to serve as a viable system for electricity generation. The electrical production of the generator only saved about 2 cents per year based on current Arizona electricity rates. In the end it was determined that the project was not a sustainable energy generation system and did not warrant further experimentation.

Description
Consumption of seafood poses a substantial threat to global biodiversity. Chemical contamination found in both wild-caught and farmed seafood also presents significant health risks to consumers. Flame retardants, used in upholstery, plastics, clothing, and other products to reduce fire danger, are of particular concern as they are commonly found in the marine environment and permeate the tissues of fish that are sold for consumption via multiple pathways. By summarizing various metrics of sustainability and the mercury content in consumed species of fish and shellfish, researchers have found that high levels of chemical contamination was linked with lesser fishery sustainability. I conducted a literature review of flame retardant content in seafood to further compare contamination and sustainability in addition to the initial analysis with mercury. My review suggests that the widespread issue of fishery collapse could be alleviated by demonstrating to stakeholders that many unsustainable fish stocks are mutually disadvantageous for both human consumers and the environment. Future research should address the need for the collection of data that better represent actual global contaminant concentrations in seafood.

Description
Over the last century, society has begun to acknowledge and observe how human actions are negatively impacting the environment. Sustainable living is becoming more adopted into daily lives, including a focus on waste management and recycling. Previous informal studies have proposed that coffee grounds can be recycled and added to the soil to increase plant productivity. The objective of this experiment was to test how different concentrations of roasted coffee grounds would affect the overall plant productivity when introduced in the soil of various plant types and environmental atmospheres. Three treatments were selected (100% potting mix, 50% potting mix/50% coffee grounds, and 25% potting mix/75% coffee grounds) and applied to 3 acid-tolerating plants (radish, basil, and parsley). Each of these treatments were grown in 2 different environments, where one was planted in a Tempe, AZ backyard while the other group was planted in a lab environment, locating at Arizona State University's Tempe Campus. Each plant with its respective treatments (plant type, coffee ground treatment, and environment) had 10 identical plants for statistical accuracy, resulting in a total of 180 plants grown, observed, and analyzed for this 3-month long experiment. The plant development, plant height, length of roots, quantity of leaves, and environmental observations were recorded and used to define plant productivity in this investigation. The experiment demonstrated low survival rates in all groups including the control group, suggesting a flaw in the experimental design. Nonetheless, the experiment showed that among the surviving plants, the 75% treatment had the largest negative impact on plant productivity. The measured root lengths and leaf quantity had various results across each plant group, leaving the hypothesis unverified. Overall, the experiment was effective in demonstrating negative impacts of great concentrations of coffee grounds when introduced to various plants, but further investigation with an adjusted experimental design will need to be completed to reach a reliable conclusion.

Description
The purpose of this research is to study the effect of angle of acceptance and mechanical control system noise on the power available to a two-axis solar concentrating photovoltaic (CPV) system. The efficiency of a solar CPV system is greatly dependent on the accuracy of the tracking system because a strong focal point is needed to concentrate incident solar irradiation on the small, high efficiency cells. The objective of this study was to evaluate and quantify tracking accuracy for a performance model which would apply to similar two-axis systems. An analysis comparing CPV to traditional solar photovoltaics from an economic standpoint was conducted as well to evaluate the viability of emerging CPV technology. The research was performed using two calibrated solar radiation sensors mounted on the plane of the tracking system, normal to the sun. One sensor is held at a constant, normal angle (0 degrees) and the other is varied by a known interior angle in the range of 0 degrees to 10 degrees. This was to study the magnitude of the decrease in in irradiance as the angle deviation increases. The results show that, as the interior angle increases, the solar irradiance and thus available power available on the focal point will decrease roughly at a parabolic rate, with a sharp cutoff point at angles greater than 5 degrees. These findings have a significant impact on CPV system tracking mechanisms, which require high precision tracking in order to perform as intended.
