Wood Waste And Race: The Industrialization Of Biomass Energy Technologies And Environmental Justice, Sarah Mittlefehldt

Journal Articles

In the 1980s, engineers developed new ways to use one of humanity’s oldest fuel sources—wood—to create electrical power. This article uses envirotechnical analysis to examine the development of a wood-burning power plant in Flint, Michigan, and argues that when public officials began working with major energy corporations to build industrial biomass facilities in the 1980s and 1990s, new energy technologies designed to run on renewable fuels became part of an entrenched fossil fuel–based power structure that maintained deep historical inequalities. Like other examples of environmental injustice, the burdens of industrial-scale biomass power systems tended to fall on poor, nonwhite communities. …

Livelihoods Of The People Of Mazumbai: A Collection Of Stories And Portraits, Tanga Region, Tanzania, Joseph Baldus

Independent Study Project (ISP) Collection

Despite rapid urbanization in Tanzania, agriculture remains central to the nation, the economy, and the livelihoods of a large portion of the population. Smallholder farmers account for the vast majority of agricultural production, yet are an extremely vulnerable population due to poverty, single-sourced income, and climate-dependency for both subsistence and cash-crop agriculture (Rapsomanikis, 2015). This report explores these dynamic rural livelihoods through interviews and portrait photographs in a case study on Mazumbai, Tanga region, Tanzania. Semi-structured interviews explore the people’s modes of economic subsistence, domestic lives, education, challenges, and life stories. Excerpts from these interviews combined with portrait photographs create …

Sea Squad, Liam Geary Baulch

The Goose

The Sea Squad is a band of cheerleaders against climate change. Taking action as a team in formation, they gather momentum, inviting all people to cheer with them, mimicking the infinitely expandable nature of the seas' molecular structure. The work was developed and performed as a bilingual project at Est-Nord-Est in Saint-Jean-Port-Joli, Quebec, Canada, and has since been performed and exhibited internationally. The following poems are some of the chants that Sea Squad use to get a crowd cheering together against climate change.

Short-Term Low Salinity Mitigates Effects Of Oil And Dispersant On Juvenile Eastern Oysters: A Laboratory Experiment With Implications For Oil Spill Response Activities, Meagan N. Schrandt, Sean Powers, F.Scott Rikard, Wilawan Thongda, Eric Peatman

University Faculty and Staff Publications

Following the Deepwater Horizon oil spill, eastern oyster (Crassostrea virginica) reefs in the northern Gulf of Mexico were exposed to oil and various associated clean-up activities that may have compromised oyster reef health. Included in the exposure was oil, dispersant, and in some locales, atypical salinity regimes. Oil and dispersants can be detrimental to oysters and the effects of salinity depend on the level. In addition to these extrinsic factors, genetic diversity of oyster populations may help the oysters respond to stressors, as demonstrated in other systems. We used a 3×3×2 factorial design to experimentally examine the effects …

Regulation Of Dissolved Arsenic Using Zero-Valent Iron With Gypsum And Sulfate Reducing Bacteria: Laboratory Microcosm And Column Studies, Ying Liu

Dissertations, Theses, and Capstone Projects

Bench scale microcosm incubation was first conducted in two stages to examine the removal of arsenic (As) by zero-valent iron (ZVI) in the presence of sulfate reducing bacteria, gypsum as well as organic substrates under anaerobic condition. About 98% of dissolved As was removed from solution within 20 days with concurrent decrease of dissolved sulfate and growth of bacterial population. Mineralogy analysis using SEM-EDS found the formation of iron sulfide and Fourier-transformed infrared (FTIR) spectroscopy analysis indicates that some As is associated with pyrite. The main iron corrosion product was found as ferrihydrite with traces of lepidocrocite. Sequential leaching shows …

Increasing Health Threat To Greater Parts Of India Due To Crop Residue Burning, Sudipta Sarkar, Ramesh Singh, Akshansa Chauhan

Mathematics, Physics, and Computer Science Faculty Articles and Research

"Rice crop residue burning during mid-October to November every year is becoming a serious health threat because of increased burning by farmers in the states of Punjab, Haryana, and western Uttar Pradesh in northern India. Crop residue burning started in the late 1980s with the start of mechanised harvesting in Punjab. Farmers found burning to be an economical way of cleaning crop stalk residues that are left over by mechanised harvesters. In doing so, farmers ignore the impact of this practice on health and air quality in the cities located in the Indo-Gangetic Plains. In the winter season, the severity …

Three Essays On The Economics Of Controlling Mobile-Source Episodic Air Pollution, Ramjee Acharya

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cache County and the Wasatch Front, Utah have persistently experienced some of the nation’s worst air quality over the past decade. Elevated PM2.5 concentrations during wintertime “red air day” episodes frequently exceed the National Ambient Air Quality Standards (NAAQS). We investigate the possible effects of two different economic policies in controlling these regional problems. Adapting a model originally developed to calculate the social investment necessary to control nationwide disease outbreaks, we estimate an optimal preventative capital stock (for example, investment in public transportation) of between $4.1 million and $14.1 million to control red air day episodes in Cache County, and …

Estimation Of The Relationship Between Satellite-Derived Vegetation Indices And Live Fuel Moisture Towards Wildfire Risk In Southern California, Kristen Whitney, Seung Hee Kim, Shenyue Jia, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

Southern California possesses a Mediterranean climate having semi-arid to arid characteristics and contains shrubland areas at high risk to wildfire. To assess wildfire danger, fire agencies have been monitoring the moisture of vegetation, called live fuel moisture (LFM), using field-based sampling. Unfortunately, spatial and temporal resolution of live fuel moisture data are significantly limited because sampling is labor intensive. Remote sensing satellite data has been used to monitor vegetation moisture content and health of shrublands. Therefore, a potential approach to overcome the limitations of manual measurements of live fuel moisture is to use vegetation indices (VIs) derived from satellite data. …

Assessment Of Indoor & Outdoor Black Carbon Emissions Rural Areas Of Indo-Gangetic Plain: Seasonal Characteristics, Source Apportionment And Radiative Forcing, Mohammad Arif, Rajesh Kumar, Ramesh Kumar, Eric Zusman, Ramesh Singh, Akhilesh Gupta

Mathematics, Physics, and Computer Science Faculty Articles and Research

Black Carbon (BC) has been widely recognized as the second largest source of territorial and global climate change as well as a threat to human health. There has been serious concern of BC emission and its impact in Indo-Gangetic Plains (IGP) due to the use of biomass and fossil fuels for cooking, transportation and industrial activities. An attempt has been made to study indoor (Liquefied Petroleum Gas- LPG & Traditional cookstoves users households) and outdoor concentrations; seasonal characteristics; radiative forcing and source of apportionment of BC in three districts (Sitapur, Patna and Murshidabad) of IGP during January to December 2016. …

Evaluation Of Hand-Dug Wells In Rural Haiti, Haley E. Schram, Peter J. Wampler

Open Access Publishing Support Funded Articles

Water resources, especially safe, potable water, are limited for many Haitians. In areas where shallow groundwater is available, many household water needs such as laundry, bathing, and cooking are supplied by hand–dug wells. In order to better understand the water quality and prevalence of these household wells, 35 hand–dug wells were surveyed and sampled near the Hôpital Albert Schweitzer in Deschapelles, Haiti. Water samples were collected and tested for fecal coliform and Escherichia coli using the IDEXX Colilert–18 method. Of the samples collected, 89 percent were determined unsafe to use as a drinking water source based on the World Health …
