Current State Of Seagrasses In Zanzibar: Impacts Of Coastal Economic Activities And Marine Protected Areas On Seagrass Cover, Danielle Purvis, Narriman Jiddawi

Capstone Collection

Seagrass meadows are located abundantly in Zanzibar, Tanzania and provide essential ecosystem services, such as sediment nutrient enrichment and blue carbon sequestration. However, seagrasses have been less researched or protected than other marine ecosystems. Although environmental variables affect seagrass health, evidence suggests that anthropogenic impacts are their greatest threats. The rapid expansion of seaweed farming and tourism and widespread use of harmful small-scale fishing practices in Zanzibar have contributed to the degradation and removal of seagrass meadows, disrupted coastal marine food chains, and reduced local biodiversity that seagrasses support. Public or private marine protected areas (MPAs) protect most of Zanzibar’s …

Examining The Benefits Of A Sustained Balance And Fall Prevention Programming For Independent Older Adults Living In A Community Setting, Noah Davis

Legacy Theses & Dissertations (2009 - 2024)

Falls have been an identified public health and social problem since the 1980’s and now recognized as a global health problem in many of the developed nations. The National Council on Aging and the Centers for Disease Control and Prevention acknowledge many evidence-based fall prevention programs. However, there are identified concerns to the programs; for example, a lack of sustained programming for older adults in the community setting. The literature review on fall prevention interventions identifies that few programs are sustained after two years, primarily due to a lack of funding and a lack of interest by older adults.

Homeowners’ Lived Experience In Developing And Using Accessory Dwelling Units In Ireland, Geraldine Mary Hurley

Walden Dissertations and Doctoral Studies

Researchers have explored the role of accessory dwelling units (ADUs) as a form of housing since at least the 1970s. Such exploration has taken place across a number of different disciplines, including gerontology, housing affordability, and urban planning. The literature tends to focus on specific policies, however, rather than on the lived experience of the homeowners impacted by those policies. Ireland’s national and local governments have yet to acknowledge the potential use of ADUs as a contributing solution to ongoing problems with housing supply, housing affordability, and homelessness, despite a government-declared national housing crisis. Formal research on ADUs in the …

The Bay Area Rail System: A Sustainable Network Or A Social Equity Phenomenon?, Whitney Libunao

Master's Projects and Capstones

Sustainable transportation, as it relates to sustainable development, aims to achieve economic stability, social equity, and environmental preservation via transit projects. However, gentrification processes and transit-oriented developments or TODs have attracted more households inward toward reinvested transit-centric areas. The San Francisco Bay Area, California has continued to see positive economic growth, with that, higher-income households inhabiting more centralized locations. Native low-income residents have started to feel displacement pressures on both a social and economic scale. Over time, displacement risk inevitably leads to residential displacement where low-income families are forced to relocate to distant, more affordable neighborhoods. As more distance separates …

Ecology And Christian Education: How Sustainability Discourse And Theological Anthropology Inform Teaching Methods, Chad Rimmer

Consensus

This paper will sketch theoretical synergies between sustainability discourse and a Christian ecotheological approach to religious education, and point to pedagogical possibilities for bridging the two disciplines. Theology and natural science operate with certain anthropological assumptions. Those underlying anthropologies inform the teaching methods of environmental and religious education. Anthropologies that conceive of human being outside of ecological relationships are a root problem of our current ecological crisis. Many economic, political and social discourses colonize people from the land, particularly children, exacerbating the root causes of sustainability. This paper affirms that linking sustainability discourse and religious education is a way to …
