Climate Change, Malnutrition, And Hiv: The Impact Of Food Insecurity On Hiv Response In Sub-Saharan Africa, Olivia Walshak Oct 2023

Climate Change, Malnutrition, And Hiv: The Impact Of Food Insecurity On Hiv Response In Sub-Saharan Africa, Olivia Walshak

Independent Study Project (ISP) Collection

Climate change is a key driver of an unprecedented global food crisis, exacerbated by rising temperatures and the vulnerability of crop yields. Sub-Saharan Africa is particularly susceptible, and case studies demonstrate the fragility of food systems in the region, leading to severe food insecurity and famine in the face of climate shocks.

There are a variety of health implications, particularly the syndemic relationship between malnutrition and HIV. HIV interacts bidirectionally with malnutrition, creating a vicious cycle of poor clinical outcomes. Expanding access to antiretroviral therapy in Sub-Saharan Africa is hindered by rampant food insecurity, including inadequate food intake, reduced dietary …


Surveillance Systems In Western Kenya: Methods, Perceptions, And Effectiveness, Marissa Duffy Oct 2023

Surveillance Systems In Western Kenya: Methods, Perceptions, And Effectiveness, Marissa Duffy

Independent Study Project (ISP) Collection

Surveillance is an important tool in monitoring and evaluating infectious disease patterns and trends. Surveillance is vital because it aids public health officials and medical professionals in creating better prevention methods and efficiently managing outbreaks. Kenya is home to many noncommunicable diseases making it an important location to conduct disease surveillance. Within Kenya, each county has its own surveillance unit which tracks and controls outbreaks. In addition, government run surveillance systems were established to determine disease burden, incidence, and patterns in specific at-risk communities around Kenya. One of these major surveillance systems is Population-Based Infectious Disease Surveillance (PBIDS) which has …


Representations And Realities: Misali Island's Biodiversity In Hybrid Narratives, Justin Ross Whitney Oct 2023

Representations And Realities: Misali Island's Biodiversity In Hybrid Narratives, Justin Ross Whitney

Independent Study Project (ISP) Collection

Marine Protected Areas (MPAs) are complex organisms that ebb and flow between strict and unyielding conservation doctrines often at the cost of community engagement. Misali Island is different. Conceived and advocated for by community members, this organism has navigated a tumultuous tenure of environmental degradation, periods of high and low funding, and a looming tourism presence. On top of these challenges has been a growing fishing community attempting to share in the bounty of this shockingly biodiverse setting. This study sorts through the grey space of Misali Island by applying a hybrid narrative that interfaces the marine context of the …


Always Sunny In Zanzibar: Exploring Solar Power On The Island, Quinn Brannan Oct 2023

Always Sunny In Zanzibar: Exploring Solar Power On The Island, Quinn Brannan

Independent Study Project (ISP) Collection

As Zanzibar continues along its developmental path, the island’s energy infrastructure takes on a central role in future plans for growth. Critically, as the population grows and tourist presence is predicted to increase, the island is presented with the combined problem of supplying a greater volume of energy, while also providing a more reliable source to its existing populace. In this study, I will examine existing solar energy systems for capacity, accessibility, and reliability, as well as evaluate their efficacy in providing a functional source of power, both now and in the future. I conduct interviews with assorted stakeholders in …


Analyzing Human - Nonhuman Primate Conflict Mitigation Techniques In Mto Wa Mbu, Northern Tanzania, Lily Adams Oct 2023

Analyzing Human - Nonhuman Primate Conflict Mitigation Techniques In Mto Wa Mbu, Northern Tanzania, Lily Adams

Independent Study Project (ISP) Collection

Human – non-human primate conflict is particularly crucial due to primates’ high capacity to live among human populations. The study to analyze Human - Nonhuman Primate Conflict Mitigation Techniques, was carried in November 2023 at Mto wa Mbu, Northern Tanzania. To analyze techniques currently being used to mitigate human – non-human primate conflict, this study collected data through semi-structured interviews. Over 87% (n=35) of respondents used multiple mitigation techniques simultaneously. 80% of respondents (n=32) reported using projectiles to ward off foraging primates, 75% of respondents (n=30) reported using loud noises (made either by the voice/body or by manipulating noisemakers), 67.5% …


Coastal Morphology And Sediment Deposition On Adjacent Coral Reefs At Misali Island, Sophia Rosati Apr 2023

Coastal Morphology And Sediment Deposition On Adjacent Coral Reefs At Misali Island, Sophia Rosati

Independent Study Project (ISP) Collection

Terrestrial and marine ecosystems are frequently interpreted under separate lenses. On a 1 km wide island, however, these two sciences are inextricably tied. Misali Island, a small coralline island in the Indian Ocean, has been largely uninhabited for its entire history, making this coastal interface unique. In this study, Misali Island is used as a study region to demonstrate how natural processes are materializing in the Zanzibar Archipelago. Methods employed, both geological and marine, work to understand the erosional circumstances of Baobab Beach and the inherent effects on local coral reefs. Results show that Misali’s northeastern beachfront is currently under …


Abcds Of Triggerfish In Pemba And Misali Island: Abundance, Biodiversity, Behaviour, Cultural Significance And Distribution, Hannah Ng Shueh Yi Apr 2023

Abcds Of Triggerfish In Pemba And Misali Island: Abundance, Biodiversity, Behaviour, Cultural Significance And Distribution, Hannah Ng Shueh Yi

Independent Study Project (ISP) Collection

This study takes a socioecological approach to understanding triggerfish (Balistidae) in Pemba Island, using Misali Island reefs as a sample ecological site. Two reef sites on Misali Island and three of four districts in Pemba were observed during the study. The abundance of Balistipus undulatus at one of two study sites is close to the maximum carrying capacity of the reef. Overall observed biodiversity was low. Behavioural trends point to distinct species specific defence strategies and species aggression taking different forms. Triggerfishes cultural significance was primarily as a food fish, though it is not highly sought after. With polarised responses …


Wishing For Water While Fleeing Their Farms: A Study Of Water Scarcity And Internal Migration In Tunisia, Tyler Rak Apr 2023

Wishing For Water While Fleeing Their Farms: A Study Of Water Scarcity And Internal Migration In Tunisia, Tyler Rak

Independent Study Project (ISP) Collection

How does water scarcity and limited water access impact internal migration? I argue that water scarcity and limited access to water is likely to increase internal migration in Tunisia. The mechanism through which I will investigate this relationship is in the agricultural sector. In this research, I found that water scarcity does exist in Tunisia and that scarcity impacts the economy, employment, and perceptions of rural areas in Tunisia. This, in turn, likely contributes to internal migration, although my research could not conclude whether water scarcity acts a causative factor to internal migration. This topic has become more prevalent than …


Evaluating The On-Site Impacts Of The Ambatovy Project Through The Lens Of Environmental Justice, Nick Karlik Apr 2023

Evaluating The On-Site Impacts Of The Ambatovy Project Through The Lens Of Environmental Justice, Nick Karlik

Independent Study Project (ISP) Collection

In Madagascar, sustainable development has been established and maintained by dominant foreign actors to reconcile neoliberalism with globalized conceptions of environmental protection. The Ambatovy mining and refining project has emerged as a prominent example of this developmental mode; Ambatovy is the largest economic enterprise in the history of the country and one of the largest and most productive mining operations in the world, generating billions of dollars in revenue for a country that remains among the poorest in the world while offsetting its impact on endemic biodiversity and forest habitat through conservation initiatives. At the same time, the evaluative framework …


Community Participation And Perspectives Of Ambondrolava Mangrove Restoration Project, Nadine Shannon Apr 2023

Community Participation And Perspectives Of Ambondrolava Mangrove Restoration Project, Nadine Shannon

Independent Study Project (ISP) Collection

Madagascar’s mangrove forests are intertidal ecosystems that provide numerous valuable ecosystem services but are nonetheless under pressure from large amounts of deforestation. On the southwestern coast of Madagascar, the village of Ambondrolava practices community led management of the mangrove and its resources. This research project studied the evolution of the mangrove area using GIS data, and investigated, through interviews, the relationship between the local community of Ambondrolava and the organizations that manage the mangrove ecosystem. From 2000 to 2018, the zone of the mangrove has experienced a net loss in area every year, despite reforestation efforts. Most community members interviewed …
