Daugherty Water for Food Global Institute: Faculty Publications

The 2014 Sustainable Groundwater Management Act (SGMA) created, for the first time and on an unprecedented scale, a mandate to change how groundwater is managed statewide in California. While enacting SGMA was a tremendous step forward, communities and water districts now face the considerable challenge of creating successful groundwater management programs. This report is aimed at helping California’s water managers, public water agencies, county commissioners, city planners, and others better understand the suite of tools and approaches that can be used to enhance the sustainable management of groundwater. Specifically, we consider four categories of management tools—regulatory, incentive-based, agency supply augmentation …

Chikungunya: India, Allison Harvey

Global Issues in Public Health

A communicable disease is an infectious disease, transmissible by direct contact with an affected individual or the individual’s discharges, or by indirect means. The more direct contact people have, the more disease spreads explaining why larger populations have more outbreaks of communicable diseases. India, in particular, has one of the biggest population sizes and makes them susceptible to those diseases. Many can be fatal. However, other diseases, such as chikungunya, are also dangerous viruses that put specific populations at risk for health problems if infected. With chikungunya symptoms such as fever or rashes may develop. Some symptoms such as joint …

Cholera: Uganda, Emilie Verran

Global Issues in Public Health

The bacterium Vibrio cholerae, when ingested, infects the intestines and causes a communicable diarrhea disease called cholera. Outbreaks of cholera occur in areas with poor sanitation and sewage treatments where fecal material of an infected person contaminates the water. These areas include Southeast Asia, Haiti, and sub-Saharan Africa, including Uganda. From 2011-2016, an analysis of Ugandan cholera data showed ‘hot spots’ of cholera cases in fishing communities with incidence rates as high as 120-998 cases per 100,000 people. An analysis of these same districts from 2011-2015 showed an average Case-Fatality Ratio of 2.4%, with the worst district as high …

Low Vaccination Rates: Africa, Karen Ruiz

Global Issues in Public Health

Vaccination is a treatment that produces immunity, protecting individuals and general populations from infectious and often deadly diseases. Low vaccination rates have for a long time been a pervasive issue in the continent of Africa. There are many extenuating circumstances that become contributory causes for low rates of populations being vaccinated. These circumstances can be in relation to the health professionals and facilities that distributes vaccinations, lack of resources in health facilities, false determiners for children’s eligibility, etc. Other contributory causes concern the general environments in which people live. These contributory causes can present barriers for accessing health services and …

Outdoor Air Quality, Taylor Curley

Global Issues in Public Health

Outdoor air quality is a significant issue for the entire world. It affects any and all people, but is more of an issue in low-income countries and among people that are more susceptible to respiratory issues such as young children, pregnant women, the elderly, and people who already suffer from respiratory problems like asthma. Poor air quality is caused by the burning of fossil fuels which releases particles and chemicals into the air like carbon dioxide, particulate matter, and nitrogen to name a few. It can cause multiple health issues such as respiratory problems to people who are exposed to …

Climate Change: Antarctica, Marika Vi

Global Issues in Public Health

Climate change is a public health issue that affects the entire globe. These effects include the rising in sea levels, shrinking of mountain glaciers, accelerating ice melt, and shifts in flower and plant blooming. The cause of climate change is due to what is known as the “greenhouse effect.” This is where certain gases block heat from getting out of the atmosphere. The cause of this effect is due to many factors like the overuse of fossil fuels and overpopulation. The impact of climate change on the Antarctic, to be specific, is that it has been seen to affect the …

Dengue, Edward Ramos

Global Issues in Public Health

The dengue virus puts one third of the world’s population at risk. Humans carry the virus and mosquitoes pick it up and are able to spread to more people. As long as there are mosquitoes near you there is the possibility that you could become infected with the dengue virus. However, people living in tropical areas that are poverty stricken are much more likely to bit by these mosquitoes and developed dengue fever. Things like mosquito netting and proper plumbing help lower the amount of these mosquitoes from biting people. There are very few treatments for when a person gets …

Global Issues in Public Health

Sub-Saharan Africa is the large area situated south of the Saharan desert. It is considered one of the poorest regions in the world; the territory faces many challenges in respect to public health. One of the most important issues that sub-Saharan Africa faces is malaria. It is spread through the female Anopheles mosquito. Environmental factors of sub-Saharan Africa heavily influence the rates of incidence in the region due to high populations of mosquitoes. Social determinants of health affect risk in the sub-Saharan populations. Little access to healthcare, built environment, and education all impact incidence of malaria in the region. Children …

Indoor Air Quality: The United States, Paola Solano

Global Issues in Public Health

Indoor air quality is one of today’s most prevalent public health concerns. It is quite shocking to learn that almost all populations in the world can be affected. We oftentimes expect to be home and be safe, but our indoor environment can also be harming to our health. In certain regions, there is more pollution indoors than outdoors due to the surrounding environment. There exist numerous factors that can cause poor air quality. Some of the most common causes include mold, carbon dioxide, moisture damage, and other indoor air contaminants. Although alarming, there are many practices that can better the …

Water Scarcity: Sudan, Catherine Priebe

Global Issues in Public Health

Water scarcity is an environmental global problem that will only become more pressing as time goes on. It is a public health issue that affects every continent, although certain areas of the world are facing more serious water scarcity than others such as Sudan. Populations that are more vulnerable to the effects of water scarcity are the poor, women, children, and those living in areas of political unrest. For example, South Sudan’s urban water systems have been damaged during recent warfare. Water scarcity is also an issue that disproportionately affects women who are forced from a young age to travel …

Mchm (4-Methylcyclohexane Methanol) Influences The Predator-Prey Interaction Between Danio Rerio And Daphnia Magna, Anna C. Wagner

Electronic Theses and Dissertations

Chemical contamination alters organism-level traits, such as activity and feeding, that can ultimately affect aquatic trophic interactions. Despite the importance of predator-prey relationships in aquatic communities, chemical toxicity is often tested on single species prior to use. For example, 4-methylcyclohexane methanol (MCHM) used in industrial coal-cleaning enters the environment regularly from low-level contamination during disposal and occasionally in high concentrations following accidental spills, but its effects on fish-zooplankton interactions remain unknown. It was hypothesized MCHM exposure affects zebrafish and D. magna swimming behavior differently when exposed individually or together, and ultimately affects their relationship. Zebrafish and D. magna were exposed …

Developing A Unified Approach To Sustainable Consumption Behaviour: Opportunities For A New Environmental Paradigm, Vivienne Byers, Alan Gilmer

Articles

Politicians and national policy makers seek to encourage individuals to engage in a wide range of pro-environmental practices to address both discrete environmental problems and major global challenges such as climate change. Theoretically, the field of behavioural management in environmental consumption which seeks to change holarchic open human systems, is much contested. This paper proposes to develop a synthesized conceptual framework embracing a unified approach that addresses the systematic, structural, and institutional perspectives on how consumption, through public policy initiatives, can be developed and changed to reflect a deeper ecological foundation. This approach considers the debate regarding policy and behavioural …

The Paris Agreement binds all nations to undertake ambitious efforts to combat climate change, with the commitment to Bhold warming well below 2 °C in global mean temperature (GMT), relative to pre-industrial levels, and to pursue efforts to limit warming to 1.5 °C^. The 1.5 °C limit constitutes an ambitious goal for which greater evidence on its benefits for health would help guide policy and potentially increase the motivation for action. Here we contribute to this gap with an assessment on the potential health benefits, in terms of reductions in temperature-related mortality, derived from the compliance to the agreed temperature …

Gulf and Caribbean Research

Grand Bay National Estuarine Research Reserve (GBNERR) is a 7500 ha protected area in Jackson County, MS. In 2005, a levee breach at a fertilizer manufacturing facility released highly acidic and phosphate—rich wastewater into the reserve. A second spill occurred in September 2012 following Hurricane Isaac. We used orthophosphate (PO₄^3-) concentrations to categorize the 2 events, post— events, and non—impact periods between the 2 spills. We examined spatial and temporal patterns in nutrients, chlorophyll, pH, and other parameters within and between monitoring stations. After the first event, pH at the Bangs Lake water quality station decreased to …

Post-Fire Regeneration And Fuel Succession Patterns In Hesperocyparis Bakeri Forests, Bret Anthony Mcnamara

Cal Poly Humboldt theses and projects

Climate change is predicted to cause widespread redistribution of suitable tree habitats, as well as increase the size and frequency of wildfires in the western United States during the forthcoming century. Rare serotinous conifers may have heightened sensitivity to the impacts of both fire regime and climate shifts for multiple reasons. First, the rapid spatial rearrangement of suitable habitat will disproportionately affect trees with constrained seed dispersal capabilities, and limited dispersal is a trait associated with some genera of serotinous trees. Second, a number of serotinous conifers depend on fire disturbances for regeneration, though with the expected increase in annual …

Presence And Potential Sources Of Pharmaceutical And Personal Care Product Chemicals In Messalonskee Lake, Alyssa T. Kullberg

Honors Theses

Pharmaceuticals and personal care product chemicals (PPCPs) represent a large group of contaminants that are mostly not regulated in surface or drinking water and whose presence and environmental and health impacts are poorly understood. We investigated the presence and potential sources of 18 PPCPs in Messalonskee Lake. We collected samples four times over the summer of 2017 at 13 sites around the lake. Samples were tested for PPCPs using liquid chromatography-tandem mass spectrometry. We detected five out of the 18 PPCPs we tested for at the ng/L level: caffeine, 1,7-dimethylxanthine, acetaminophen, sulfachloropyridazine, and amphetamine. PPCPs showed a significant positive correlation …

Dust Control Examination Using Computational Fluid Dynamics Modeling And Laboratory Testing Of Vortecone And Impingement Screen Filters, Ashish R. Kumar

Theses and Dissertations--Mining Engineering

Heavy industries, such as mining, generate dust in quantities that present an occupational health hazard. Prolonged exposure to the respirable dust has been found to result in many irreversible occupational ailments in thousands of miners. In underground mining applications, a variety of scrubbing systems are used to remove dust near the zones of generation. However, the wire-mesh type fibrous screens in the flooded-bed dust scrubbers used on continuous miners, are prone to clogging due to the accumulation of dust particles. This clogging results in a reduced capture efficiency and a higher exposure to the personnel. This research establishes the Vortecone, …

The Role Of Environmental Filtering In Structuring Appalachian Tree Communities: Topographic Influences On Functional Diversity Are Mediated Through Soil Characteristics, Julia I. Chapman, Ryan W. Mcewan

Biology Faculty Publications

Identifying the drivers of community assembly has long been a central goal in ecology, and the development of functional diversity indices has provided a new way of detecting the influence of environmental gradients on biotic communities. For an old-growth Appalachian forest, we used path analysis to understand how patterns of tree functional diversity relate to topography and soil gradients and to determine whether topographic effects are mediated through soil chemistry. All of our path models supported the idea of environmental filtering: stressful areas (high elevation, low soil moisture, low soil nutrients) were occupied by communities of low functional diversity, which …

The Effect Of The Total Maximum Daily Loads(Tmdl) Management Implementation Plan On Total Phosphorus(Tp), Jaejeong Ma April

MPA/MPP/MPFM Capstone Projects

The Ministry of Environment of the Republic of Korea has been making efforts to improve water quality and the health of the aquatic ecosystems of the inland waters. Establishing water quality standards for point sources and permissible wastewater emission standards to achieve the target environmental standard were part of the efforts. Nevertheless, water quality indexes such as Biochemical Oxygen Demand(BOD) and Chemical Oxygen Demand(COD) has not improved significantly. Also, harmful cyanobacteria blooms have frequently been occurred, which, in particular, has brought people to lose faith in the environmental policy and has created anxiety about drinking water. As the solution, the …

Colonialism And Its Aftermaths In Vieques, Puerto Rico: How U.S. Hegemony Led To Contamination, A Superfund Site, And Local Mistrust, Kaya Mark

Scripps Senior Theses

After sixty-two years of U.S. military testing, the small Puerto Rican island of Vieques and its residents continue to fight against ongoing environmental and social effects of U.S. hegemony. Starting with the arrival of the Spanish, then with U.S. occupation and use of Vieques as a military stopover, Viequense residents are used to U.S. governmental presence on their land. Despite the military’s removal from Vieques in 2003, many local residents have a fundamental lack of trust for the U.S. government. Because of this lack of trust and transparency with U.S. governmental actions in the post- World War II period, residents …
