In light of climate change and urban sustainability concerns, researchers have been studying how residential landscape vegetation affect household water consumption and heat mitigation. Previous studies have analyzed the correlations among residential landscape practices, household water consumption, and urban heating at aggregate spatial scales to understand complex landscape decision tradeoffs in an urban environment. This research builds upon those studies by using parcel-level variables to explore the implications of vegetation quantity and height on water consumption and summertime surface temperatures in a set of single-family residential homes in Tempe, Arizona. QuickBird and LiDAR vegetation imagery (0.600646m/pixel), MASTER temperature data (approximately 7m/pixel), and household water billing data were analyzed. Findings provide new insights into the distinct variable, vegetation height, thereby contributing to past landscape studies at the parcel-level. We hypothesized that vegetation of different heights significantly impact water demand and summer daytime and nighttime surface temperatures among residential homes. More specifically, we investigated two hypotheses: 1) vegetation greater than 1.5 m in height will decrease daytime surface temperature more than grass coverage, and 2) grass cover will increase household water consumption more than other vegetation classes, particularly vegetation height. Bivariate and stepwise linear regressions were run to determine the predictive capacity of vegetation on surface temperature and on water consumption. Trees of 1.5m-10m height and trees of 5m-10m height lowered daytime surface temperatures. Nighttime surface temperatures were increased by trees of 5m-10m height and decreased by grass. Houses that experienced higher daytime surface temperatures consumed less water than houses with lower daytime surface temperatures, but water consumption was not directly related to vegetation cover or height. Implications of this study support the practical application of tree canopy (vegetation of 5m-10m height) to mitigate extreme surface temperatures. The trade-offs between water and vegetation classes are not yet clear because vegetation classes cannot singularly predict household water consumption.

My Honors thesis examines how promotoras, otherwise known as community health workers, can be beneficial to a community and any challenges that might be faced when implementing this program. My honors thesis will provide the history of promotoras, context on various health issues Latinx face historically and with the context of the COVID-19 pandemic, and finally address the findings of my interviews and shadowing of promotoras.

The Phoenix area, is known for suburban sprawl which did not happen in isolation but was the result of many external factors. It was not just large environmental and cultural factors that changed over time, but the actual physical characteristics of sprawl that have changed from community to community over the decades. Characteristics like physical size of houses and lot size, along with changes in the residential and commercial design and building style have changed from around the 1950s to present day, with homes being larger and covering more of each parcel. These characteristics were analyzed in 21 communities in the Phoenix area that were built from 1950 to 2019 to find how these characteristics have changed over time. While the issue of sprawl will never fully go away, by learning what the characteristics are that make up the definition of sprawl, stakeholders like cities, planners, and developers will have better knowledge for planning for tomorrow.

This research paper assesses the effectiveness of a remote garden-based learning curriculum in teaching elementary students’ basic systems thinking concepts. Five remote lessons were designed, covering different garden topics, and in order to integrate systems thinking concepts, the Systems Thinking Hierarchical Model was used. This model includes eight emergent characteristics of systems thinking necessary for developing systems thinking competency. Five students were given the remote garden-based learning lessons. Student work was evaluated for systems thinking understanding and student outcomes were compared to anticipated learning outcomes. Results suggest that elementary students are able to understand basic systems thinking concepts because student work met anticipated outcomes for four systems thinking characteristics and exceeded anticipated outcomes for one characteristic. These results are significant because they further confirm that elementary-aged students do have the ability to understand systems thinking and they contribute to a growing movement to integrate sustainability education into elementary curriculum.

Autism Spectrum Disorder (ASD) is a developmental disability that impacts one’s social interaction, communication skills (both verbal and non-verbal), and cognitive function. Autism affects 1 in 60 children. Individuals with autism have trouble understanding facial expressions or social cues, and often see the world around them differently than a neurotypical individual (mainly increased sensitivity to sounds, motion, or lighting). As the name implies, autism is a spectrum, and no two individuals are alike. As the saying goes, “When you’ve met one person with autism, you’ve met one person with autism.” Movies such as Rain Man (1988) or The Accountant (2016) showcase autistic individuals who are higher-functioning; they are able to verbally communicate and live somewhat independently. Other autistic individuals, such as my brother, Tyler, are lower-functioning. Tyler is non-verbal and unable to be independent, and our day-to-day life is greatly shaped by this.<br/><br/>One thought that haunts the parents of autistic individuals is, “What happens when they’re older?” Even more scary is the question “What will happen when I’m gone?” My brother is on the autism spectrum, and my mother describes these thoughts as ones that “keep [her] up at night.” She explains, “I think it’s important for him to be completely engaged and productive, and we have that right now because we’re in our little safety bubble...that’s going to end...and it’s kind of scary.” Around 50,000 children with autism turn 18 every year in the United States, and nearly 90% of autistic individuals lose access to the services they have relied on throughout their entire lives. My hope is that architecture can help to answer this question by providing a place for adults on the autism spectrum to learn how to eventually live and work independently in the future. By implementing certain design features and design criteria to minimize the sensory overload issues commonly experienced by individuals with autism, we can create a safe space for learning for young adults on the autism spectrum.

Voluntary carbon offsets have become a key strategy of climate action efforts in the wake of worldwide anthropogenic climate change. The voluntary carbon market has grown rapidly as more institutions gain interest in contributing to decarbonization efforts to reach emissions reduction goals. The voluntary carbon offset market has introduced decarbonization solutions through various carbon removal, reduction, and avoidance projects that provide accessibility to climate solutions and credit affordability. However, the variability of projects and verification systems has led to some criticisms of the validity and accuracy of these solutions. This thesis assesses the current state of the voluntary carbon market policies and future opportunities and trajectories for this market.

This thesis utilizes GIS mapping to analyze the severity of four threats: ocean acidification, sea surface temperature, artisanal fishing, and destructive fishing, in conjunction with coral species distribution. This project produced maps that depicts each of these threats and shows the distribution of its severity. Compiling this data we can see that ocean acidification is the most pressing threat in the Caribbean to coral and that neither type of fishing really has a large effect. A species named Madracis carmabi is also flagged to be of particular concern as it is severely threatened by both ocean acidification and sea surface temperature.
