This study addresses the landscape connectivity pattern at two different scales. The county-level analysis aims to understand how urban ecosystem structure is likely to evolve in response to the proposed development plans in Maricopa County, Arizona. To identify the spatio-temporal land pattern change, six key landscape metrics were quantified in relative to the urban development scenarios based on the certainty of the proposed urban plans with different level of urban footprints. The effects of future development plans from municipalities on landscape connectivity were then analyzed in the scaled temporal and spatial frame to identify in which urban condition the connectivity value would most likely to decrease. The results demonstrated that tremendous amount of lands will be dedicated to future urbanization, and especially urban agricultural lands will be likely to be vulnerable. The metro-level analysis focuses on a group of species that represent urban desert landscape and have different degrees of fragmentation sensitivity and habitat type requirement. It hypothesizes that the urban habitat patch connectivity is impacted upon by urban density. Two underlying propositions were set: first, lower connectivity is predominant in areas with high urbanization cover; second, landscape connectivity will be impacted largely on the interfaces between urban, suburban, and rural areas. To test this, a GIS-based connectivity modeling was employed. The resultant change in connectivity values was examined for exploring the spatial relation to predefined spatial frames, such as urban, suburban, and rural zones of which boundaries were delineated by buffering method with two criteria of human population density and urban cover proportion. The study outcomes provide a practical guidance to minimize connectivity loss and degradation by informing planners with more optimal alternatives among various policy decisions and implementation. It also gives an inspiration for ecological landscape planning in urbanized or urbanizing regions which can ultimately leads urban landscape sustainability.

Description
As a significant level of the reformation and transformation of our society has been provoked by environmental deterioration, ecological approaches in environmental design have drawn much attention from professionals as an alternative world view and also as a practical design approach. Particularly in landscape architecture, ecological understanding has been at the very core of the profession since its emergence and plays an important role in the decision making processes. While ecology supports the profession with an objective rationale, aesthetics plays another major role in providing various understandings about the aesthetic experience of people, which is rather subjective. However, the ways to seek the balance between them are still controversial. Furthermore, the conventional aesthetic value system of landscape appears to have limitations for guiding us to an appropriate appreciation, especially in dealing with newly emerging urban landscape patterns such as regeneration of post-industrial landscapes. Understanding these issues, there have been continuous attempts to describe the relation between ecology and aesthetics, suggesting that a new approach known as "ecological aesthetics," can bring us a new set of viewpoints seeking a reunion of nature and culture, and science and art. It asserts that "there is a type of beauty" in the landscape associated with its ecological health which people could aesthetically appreciate; and therefore, revealing the "hidden" beauty of nature in more visible ways should be the primary concern of today's ecological designers. This research mainly consists of extensive literature research and a case study on two landscape restructuring projects of post-industrial landscapes in Seoul, Korea. The literature research redefines the tasks of landscape architecture based on the idea of ecological aesthetics, and the case study seeks the potentials and limitations of current design projects. This research proposes a framework for landscape perception and reflects on the lessons that would be useful for better practice and research.

Despite public demand for climate change mitigation and natural open space conservancy, existing political and design efforts are only beginning to address the declining efficacy of the biotic carbon pool (C-pool) to sequester carbon. Advances in understanding of biogeochemical processes have provided methods for estimating carbon embodied in natural open spaces and enhancing carbon sequestration efficacy. In this study, the benefits of carbon embodied in dryland open spaces are determined by estimating carbon flux and analyzing ecological, social, and economic benefits provided by sequestered carbon. Understanding the ecological processes and derived benefits of carbon exchange in dryland open spaces will provide insight into enhancing carbon sequestration efficacy. Open space carbon is estimated by calculating the amount of carbon sequestration (estimated in Mg C / ha / y) in dryland open space C-pools. Carbon sequestration in dryland open spaces can be summarized in five open space typologies: hydric, mesic, aridic, biomass for energy agriculture, and traditional agriculture. Hydric (wetland) systems receive a significant amount of moisture; mesic (riparian) systems receive a moderate amount of moisture; and aridic (dry) systems receive low amounts of moisture. Biomass for energy production (perennial biomass) and traditional agriculture (annual / traditional biomass) can be more effective carbon sinks if managed appropriately. Impacts of design interventions to the carbon capacity of dryland open space systems are calculated by estimating carbon exchange in existing open space (base case) compared to projections of carbon sequestered in a modified system (prototype design). A demonstration project at the Lower San Pedro River Watershed highlights the potential for enhancing carbon sequestration. The site-scale demonstration project takes into account a number of limiting factors and opportunities including: availability of water and ability to manipulate its course, existing and potential vegetation, soil types and use of carbon additives, and land-use (particularly agriculture). Specific design challenges to overcome included: restoring perennial water to the Lower San Pedro River, reestablishing hydric and mesic systems, linking fragmented vegetation, and establishing agricultural systems that provide economic opportunities and act as carbon sinks. The prototype design showed enhancing carbon sequestration efficacy by 128-133% is possible with conservative design interventions.

Description
Now dry and broken, the Salt River once supplied a great legacy of Riparian vegetation through the Sonoran desert. This verdant landscape flourished from perennial flows of a river fed by high mountain snowmelt. However, multiple dams within those mountain canyons and channelization for the purpose of flood protection have nearly dried up the Salt. Through the process of design I examined the potential to repair, restore, and redevelop the river, choosing a site within the reach of the Salt River that currently includes an artificial retention area called Tempe Town Lake. Since 1999 a two mile portion of the river channel has contained the reservoir for the purpose of recreation and development within the city of Tempe. As I investigated the viability of restoring an urban desert river to a more natural riparian condition, I developed a master plan that merges ecological river restoration with sustainable urban development. Research into the vegetative communities historically occurring along the river's edge guided me to create a project based in ecological principles. Expanding the concrete channel to a wider river presence followed examples set by case studies and the historic character of the Salt River. A new braided low flow channel, allowed to meander with the natural currents of the river, is terraced upwards in a gentle slope that maintains current 500-year flow plains. The vegetation communities I propose to establish along the new terraced elevations are adapted from Charles H. Lowe's profile of a foothill canyon and archival research specific to this portion of the Salt River. As a way to support the reintroduction of Arizona's lost riparian plant communities, the master plan incorporates the use of greywater and A/C condensate collection from proposed developments along the river's edge. These new water systems would be substantial enough to sustain riparian vegetation creation and in addition, provide for ground water recharge. Additional developments continue the City of Tempe's goal to expand development along the river and adjacent to the downtown core. Providing for increased recreational opportunity in a river setting improves the quality of life in Tempe and sets the community apart from surrounding desert cities. By applying ecological and sustainable design and planning principles, the Salt River Diaries master plan repairs the river's flow, restores the riparian vegetation, and redevelops the edge between the city and river.

Description
The goal of this paper is to serve as a case-study of the youth climate movement at the local level, focusing on how young activists and organizers in Arizona perceive their pathways, motivators, and barriers in the climate movement. In order to answer my research question of ‘What are the different experiences of Arizona youth activists’ involvement in climate action?’, I conducted a case-study of 15 interviews with participants between the ages of 18-25 that varied in racial and gender identity, as well as the duration of their involvement. While this paper does not present a comprehensive view of all experiences of youth climate activists and organizers in Arizona, these interviews highlight the upbringing, background, and the degree of involvement of young climate organizers and activists, ultimately revealing their similar yet unique experiences in the climate movement. Even though further research, discussion, and opportunities are needed to better understand the youth climate movement as well as other emerging social movements, these participants represent the heart of the movement here in Arizona. This case-study sheds light on lived-experiences and urges readers to consider young climate activists and organizers’ varying perspectives on how to support, amplify, and implement their requests for a livable, intersectional, diverse, and inclusive future.

As an aspiring educator pursuing a degree in education, hours have been spent observing, visiting, and working in classrooms of elementary schools. In this time, it has become apparent that social studies and science are not a priority within classrooms or even schools as a whole. This dilemma caused extreme disconnect, amongst students, throughout the common and crucial science and social studies standards that should be taught and implemented daily by law. These content experiences, especially in science, expose students to skill sets and themes that are highly desired throughout higher education, the career world, and for the well-being and longevity of planet Earth.
As a solution to this problem, I created an after school program to provide staff and myself additional time to implement such curriculum and expand the depth of knowledge that students are exposed to. This positive additional time to the educational day, was able to come to life through a grant that I wrote and received to transport students from their elementary school to a local greenhouse. At the greenhouse, I was able to create a series of lessons focused on the resources needed for gardens and plant production. Through these lessons, I utilized inquiry based lesson plans to provide me with a template that was unique from typical lessons taught at school. Through these hands on experiences in our club, students were able to work at their own pace and learn about resources, soil, water, pollinators, and parts of a flower.

As a cause of negative economic, societal, and environmental effects, food waste is increasingly being seen as a sustainability issue that needs to be addressed. Reduction of food waste is preferred to recycling because it reduces the financial burden and technological innovations needed to address the issue. While there are many different approaches to reduce food waste, this paper investigates dynamic social norms as an avenue for reducing food waste. Recent studies showcased the effectiveness of using dynamic social norms to reduce meat consumption and the use of to-go cups. However, there appears to be a gap in research that investigates the impact of dynamic social norms in U.S. university community dining settings. This study piloted the use of dynamic social norms to intervene in post-consumer food waste behaviors at Arizona State University. Specifically, this study compared food waste amounts in a location with and without an intervention tool as well as conducted interviews to monitor any self-reported behavior change. Results show that dynamic social norms can promote behavior change in terms of food waste when compared to a control location without the intervention. Further, this study advocates for monitoring food habits through both quantitative and qualitative analysis in order to identify potential behavior changes that could not be captured to the same extent by a mono-methodological approach.

Over the past decade, corporate social responsibilities and sustainability has become more of a trending topic; not only amongst citizens, but within many private firms as well. Aligning operations with sustainable practices within a for-profit firm or organization has evolved into a critical focus area in order for a company to be more sustainable.
Having sustainable practices in place can be significant, but it is also important to consider employees and their perspectives, as they are the ones who implement them. The majority of the employees that work within an organization, not those that create these policies, are the ones who’s perspectives should be more strongly considered. In order to effectively implement these practices, firms can educate their employees about the initiatives or newly implemented changes to current practices. Sustainability education for employees, covering company-specific policies, improves the likelihood of participation within initiatives. Increased employee education has the potential to raise the probability that companies will see the benefits that come with enacting sustainable practices.

Description
A unit plan was created to address a need to educate and create awareness of local foods to elementary aged students. After researching local foods and problem based learning, information was consolidated and developed into a comprehensive unit plan that serves as a teacher resource guide. This unit plan was created to provide information, tools, and resources for upper elementary students from 4th to 6th grade to learn about local foods in hopes of impacting student health and knowledge as well as building a foundation for their future eating habits. Another goal of this unit plan focuses on promoting students' awareness of local foods within their community and the benefits of buying locally in general. This unit contains seven lessons aligned to the current Arizona state standards that have creative and engaging activities ranging from socratic seminars, creating a brochure, and performing skits. Each lesson contains student objectives, clearly laid out lesson plans, and the majority of supplemental materials included such as videos, handouts, Google slides, and photographs. These lessons were planned with the intention of being able to be realistically taught in a 45-60 minute class period and laid out in a way that would be easy for teachers to read and then teach without much preparation. Simple and effective assessments are integrated throughout the unit and provide a means of tracking student progress and understanding of concepts. This unit plan is designed to engage students and plant ideas in their heads about where their food comes from and how learning about local foods can be beneficial for their community and their health.
