UC Berkeley on December 7, 1941

Editor’s Note: This blog entry is the first in a series from the Regional Oral History Office (ROHO). ROHO houses thousands of oral history interviews conducted since 1954. Some of those interviews, including many with Berkeley students, faculty, and staff recall the events of 70 years ago today – the bombing of Pearl Harbor.

UC Berkeley on December 7, 1941

In a series of recent oral histories with UC Berkeley alumni, the Regional Oral History Office (ROHO) has recorded the recollections of individuals who were students at the time of the attack on Pearl Harbor – December 7, 1941. Many of them teenagers late in 1941, they are now approaching ninety years of age. These oral histories shed light on what UC Berkeley was like before the United States officially entered World War II, and provide insight as to how students, faculty, and staff reacted to the news of the event.

For countless university students — in Berkeley and around the country — the events of that day would prove to be a major turning point. While a handful of students behaved erratically or irrationally upon hearing the news, the majority of students quietly realized that the event would soon alter their existing plans and goals. Understandably, as many students worried about their own futures, most were also anxious about the safety of their families. Some worried about their friends of Japanese ancestry. Other students would remain on campus to continue their studies, and numerous faculty members carried on teaching. For other faculty and graduate students, however, the news of the attack would provoke a series of difficult choices – many joined the armed services, found jobs in the rapidly expanding defense industry, or contributed to the war effort through research for government agencies. As the events at Pearl Harbor led many to weigh choices and voluntarily leave campus, numerous students of Japanese ancestry were soon given no choice but to leave campus.

Through the lens of oral history, we can explore the place of Pearl Harbor in the collective memory of the University of California, Berkeley. This story represents but one component of our larger efforts to record and interpret the history of the WWII homefront through oral interviews. Other collections, including our numerous oral histories with faculty, staff, and administrators, speak to the significance of that date in the history of the campus.

December 1941

By many accounts, December of 1941 was shaping up to be a terrific month in Berkeley. The weather was outstanding. Many of our narrators recall the weekend as sunny and even unseasonably warm. Instead of spending time outside, however, most Cal students were busy cramming for final exams. Despite having final exams the following day, some students were taking a mental break visiting family or friends. Others were at home or in their dorm rooms studying.

Natalie Salsig, one of our narrators, recalled in a recent interview “having to study for finals in a closet with the door closed.” After Pearl Harbor, students who wanted to continue studying in the evening were forced to confront both the distractions of global events and the immediate blackouts organized along the entire coast. Salsig recalls studying for finals in the closet, a small light illuminating her books, so as not to signal to the enemy where the cities began and the Pacific Ocean ended. “It was a scary time,” Salsig remembers. Fear of an actual attack was sporadic and uneven, but uncertainty was seemingly universal.

Jack Rosston was living in a co-op in December of 1941. Usually a punctual student, he had let a paper assignment sit until the last moment – staying up late the night of December 6 in order to finish the assignment. In the early hours of the morning, he woke up to screaming. He recalls the reactions of the students on campus, explaining that a couple of students were so angered by the attack, that they were threatening to bomb the Japanese Student Association. Jack recalls the pockets of anger and threats of violence, “It horrified me at that time, and most of the kids were horrified at that.”

Nearby in Oakland, another young woman had more immediate concerns about her upcoming senior ball than world events. In 1942, Margaret Walton would enroll as a freshman at UC Berkeley, earning money during summers working in the shipyards. Months before she enrolled at Cal, she recalls sitting in her bedroom the morning of December 7, “I was still in my bedroom reading and listening to the radio because I had fallen and spilt my lip, and I was feeling very sorry for myself because my senior ball was coming up Friday night, and I had this mashed up face . . . I had the radio on and I got the news, and I ran out and told my folks.” Her family spent the rest of the day, like many Americans, glued to the radio. “It was a real shock,” Walton explained. She adds, “Well, right away you got the news that the coastline could be attacked at any minute . . . my dad had already built black out curtains to put up in the windows.” Her family spent the evening huddled into the one room of their house that would not let any light escape to the outside world – eagerly awaiting updates over the airwaves. Walton’s classmates who enrolled at UC Berkeley during the war years were asked to complete an accelerated degree program – as the war had depleted the number of available faculty and staff. Today, Walton and the classes that followed, students who shared the same unique circumstances on campus, are known as the War Alumni Classes. Members of the War Alumni Classes not only shared classes; they became bound by common experiences with rationing, blackouts, and air raid drills. Almost all of these students had at least one close friend or family member in the service.

In the Classroom

The effect on the Berkeley campus that followed Pearl Harbor was both immediate and palpable. Harry Wellman, who years later became Acting President of the University of California following the dismissal Clark Kerr in 1967, recounted that life changed quickly on the campus in the months that followed the attack. In an oral history recorded in the 1970s, he described his recollections of Pearl Harbor as a member of the Berkeley faculty. A specialist in agricultural economics, Wellman recounted that he was briefly assigned to administer the enrollment of students with the department: “I had the responsibility for insuring that classes desired by students would be given. That was not difficult. Student enrollment dropped sharply after 1941-42 and continued downward until the end of the war. In 1944-45 there were only a few undergraduate students in agricultural economics and almost no graduate students.” Indeed, so many of the students had either enlisted, or left school to assume a job in the defense industry that the department had an excess of faculty for teaching needs. Classes pertinent to the war effort, in engineering, science, and foreign languages – witnessed temporary surges in enrollment from enlisted servicemen assigned to the campus, but enrollment in many other departments declined during the war.

Other Berkeley faculty took a prominent role in the war. The most notable of these efforts included Robert J. Oppenheimer, a Berkeley physicist, who served as the scientific director for the Manhattan Project. Working engineers and physicists, his efforts led to the creation of the first atomic bomb. Numerous other Berkeley faculty and alumni worked in all types of war agencies, but their presence was felt especially within the top-secret networks of atomic weapon research at Los Alamos, New Mexico and Oak Ridge, Tennessee.

Turning Points

Activity on the Berkley campus following the initial shock of Pearl Harbor, however, was not always so eerily quiet and isolated. Even as Wellman reported dwindling enrollments in his classes, for example, he was occasionally flying to Washington to advise the government on rationing, taxes, and commodity price fixing. Others affiliated with the campus were working on research that would have an even more far-reaching influence on the modern world.

Pearl Harbor, of course, was also an important turning point for millions outside of university settings. Denise Fleig, a Berkeley resident who was returning home from work when she learned of the attack, recalls the sense of confusion at the moment she received the news. In her oral history, she describes her sense of unease, “Everybody’ll have to be drafted, now. Everybody. Oh, I wonder what that’ll mean . . . Sure going to change everything. Sure will . . . Everything’s going to change. Everything.” In her oral history, Fleig notes that, before Pearl Harbor, California seemed to be on the edge of American life – with New York and Washington as the primary focus of the nation. The attack on Pearl Harbor, however, seemed to momentarily shift national attention westward – forcing people in California to prepare for a possible attack from the Pacific.

A growing military presence in the Bay Area, coupled with a rapidly expanding wartime defense industry, brought thousands to the region. The arriving labor force, and their families, reshaped the character of the Bay Area by introducing new religions, ethnicities, and social norms. Thousands of women soon joined the labor force in the Bay Area, many taking up work at the shipyards, coming to be known as “Rosie the Riveters.” These changes not only impacted the students, faculty, and staff of the University of California, Berkeley – they were felt by everyone in the region.

Conclusion

Experts who study the creation of our long-term memories are generally in agreement that powerful experiences, such as those experienced in December of 1941, are either lodged into our memory or quickly rejected and forgotten. Memories surrounding important events are naturally and frequently recounted orally, thus reinforcing the recollection of meaningful events. A project such as the one undertaken by ROHO allows these recollections to be archived and preserved for a larger audience. Certainly, oral histories—like all sources—contain inaccuracies and inconsistencies. Human memory is, of course, fallible. Archival records, however, frequently confirm the narratives of those who are interviewed, and collecting from various sources allows the historian to mine the lived experiences of a more diverse array of historical actors. Often, the subtleties of emotion – the shock, fear, anger, and anxiety surrounding tragic events like the bombing of Pearl Harbor — are either lost altogether, or dramatically embellished in the newspaper accounts that have buttressed more traditional histories. By opening a forum for these emotional recollections to be presented, ROHO is helping to expand the historical memory.

Note: The oral history interviews quoted in this blog entry are currently in production. Transcripts of the interviews will soon be available alongside other WWII homefront oral histories here.

Reciprocity

This summer I finally crossed the equator—an important step for a Latin Americanist. I headed from Berkeley to Mexico City, my home base for the academic year, and continued to Buenos Aires and Rio de Janeiro for research and language instruction. The endless winter implied by my itinerary made for some interesting packing choices, while the multiple border crossings made for a bureaucratic labyrinth.

The hefty application fee for a Brazilian visa represents that thorn in the student traveler’s side: the Reciprocity Fee. A nonimmigrant US visa costs $140, and that is exactly what it costs a US citizen to apply for a Brazilian visa. The US Department of State explains through press releases that their fee covers the entire process of granting a visa (or not), and that the visa-granting section of Consular Affairs must be self-sustaining. Brazil, however, defines its fee entirely in Hammurabic terms: “This is because the U.S. government charges Brazilian citizens who apply for a U.S. visa a minimum of 2 mandatory fees.”  Olho por olho

Fee paid and visa in hand, I thought that my penance for being a US citizen was complete. Not so fast: I stepped off the plane in Argentina to be siphoned off into a special immigration line. A girl with a smile straight out of a toothpaste commercial informed groggy American, Australian, and Canadian tourists that they could pay 131 USD, 100 USD, or 70 USD, respectively, in cash or credit. I was first in line, and while I was blindsided (my travel guide had conveniently omitted this bit of information), the Brazilian embassy experience had served as an anesthetic, numbing me to the next bloodletting.

The Australians at the next booth were extremely friendly about the matter, but did express their surprise.

“That will be $100,” the entry fee collector announced.

“Oh…” The couple fumbled through purse and wallet and came up with a credit card.

“Each.”

“Oh!” Their eyes opened wide.

“That is how much it costs us when we want to go to your country.”

“Well, this had better be a great place!” the wife exclaimed. Her sentiment somehow came off as sincere belief in value for money rather than a complaint.

Argentina’s chipper, brazen move was in some ways easier to take than the Brazilian policy—no visa required, you only have to pay the fee every 10 years, it’s an on-the-spot credit card swipe—but for these same reasons it seemed even more like a because we can nip at the ankles.

A part of me hurrahs nations that stand up to what could be perceived as unfair, invasive treatment of their citizens, although I have a hard time going along with the self-flagellating Americans populating online travel forums, chiding any compatriot who dares complain about a denied visa. Their desperation for solidarity, championing high fees and rejected applications, seems to defend rather than reject States’ taking advantage of individuals.

A bigger part of me questions the usefulness of these policies for effecting change in US treatment of Brazilian and Argentine citizens—especially since the US already has its own reciprocity rules, disguised as “Visa Issuance Fees”, in place. The whole reciprocity game consists of sovereign states throwing their weight around at the expense of the others’ citizens, and the very borders we citizens are crossing are the ones that keep us from joining together to speak out. Widening the perspective reveals a system of governments allowing each other to effectively tax their citizens, and it’s easy to imagine some winks and nudges hidden among the finger pointing.

The Realities of Synthetic Biology

If you pay attention to the biofuels efforts in the Bay Area or read online science magazines such as Wired or New Scientist, it’s likely you’ve heard of Synthetic Biology. More of a movement than a field, Synthetic Biology envisions biology as an engineering discipline waiting to happen. Essentially, Synthetic Biology aims to circumvent or control the complexities in biology in order to build novel, effective biological systems reliably and quickly for such applications as diesel production and tumor killing bacteria. For example, imagine you want to engineer yeast to make red beer that tastes like lemon. Synthetic biology would have you pick up a “red” gene and a “lemon” gene, plug them into the yeast in a standardized, programmed way, and presto: Red lemon hefeweizen! Unfortunately, the realities of biology require much more than that. In reality, biology is so complex, few things we do ever work as expected or intended. Because of this, most synthetic biology projects quickly run into difficulty and often take years to hack together. But this hasn’t stopped synthetic biologists from making broad claims about the potential of their approaches. It’s been said that cheap biofuels, cures for diseases, and fantastic new biotechnologies are in the pipeline. Recently, however, Synthetic Biologists are encountering resistance as reality has begun to catch up to the hype.

A recent news feature in Nature Biotechnology asked some of the most prominent synthetic biologists how they define their field. The diversity and vagueness of the responses highlighted the difficulties the community has had centering itself on a set of focused objectives. Because Synthetic Biology is such a new field with no central discovery to mark its launch point, and because the application of systematic engineering to biology is so fraught with problems, the Synthetic Biology community has had trouble defining itself in concrete terms. This comes despite such efforts as the Synthetic Biology Engineering Research Center (SynBERC), an NSF-funded consortium of faculty across various universities that is intended to facilitate joint research efforts within Synthetic Biology. Some responses in the article suggested that Synthetic Biology had become more of a buzzword meant to garner federal research dollars than a productive field. For those of us in the field at the moment, this hit painfully close to home. Read the rest of this entry »

For 50 million people living in South Asia, arsenic-contaminated groundwater poses a serious health problem. Case van Genuchten, a PhD student in Civil and Environmental Engineering, is working to see if rust can be part of the solution.

This problem is most severe in Bangladesh, where more than 40 million people drink arsenic-laden water. In some places, arsenic levels are more than 100 times the World Health Organization’s recommended upper limit of 10 parts per billion. Already arsenic poisoning is evident among 40,000 Bangladeshis. And without some kind of intervention, it is expected that arsenic poisoning will eventually cause 10% of deaths in this country of 140 million.

Conventional arsenic treatment methods are too expensive for nearly half of the people drinking arsenic-contaminated water. To address this need, the Berkeley Arsenic Alleviation Group (BAAG), of which Case is a part, aims to provide affordable, sustainable technologies that remove arsenic from groundwater. Their goal is to develop a technology that removes arsenic efficiently and cheaply and that can be easily operated and maintained by local communities. One of the two techniques for arsenic removal developed by Professor Ashok Gadgil at Lawrence Berkeley National Laboratory is ElectroChemical Arsenic Remediation or ECAR. In this process, iron is placed in water with high levels of arsenic, then electricity is used to dissolve the iron which produces rust. Arsenic is known to bind very strongly to the surface of rust particles. Consequently, rust — along with the arsenic bound to its surface — can be removed from the water through filtration or settling. ECAR requires only small quantities of iron—iron nails for example are sufficient—and such low amounts of electricity that it can be powered with a car battery or solar cells.

Standard ECAR Batch Test. This how most of Case's ECAR tests are done, on a much smaller scale and with much smaller electrodes.

The goal of Case’s research is to understand ECAR’s reaction products; in other words, the formation of rust and its interaction with arsenic. The information he generates will reveal the mechanism for arsenic removal on rust and enable members of BAAG to determine the long-term stability of the waste generated through ECAR. To assess the arsenic-laden particles made in ECAR, Case uses Scanning Electron Microscopy and X-Ray Absorption Spectroscopy, which provide information on particle morphology, structure, and composition. Case’s research is driven by concern for the millions of people lacking access to safe drinking water and basic sanitation as well as a fascination with the chemistry of metals in aqueous systems. Fortunately, he’s found a project that satisfies both these interests.

This project has proved fortuitous in other ways too. An accidental discovery in the lab has added a promising new dimension to Case’s research. Although we’re most familiar with common orange rust, there are actually several different kinds of rust.  When he began the project, Case’s focus was on orange rust. But one day in the lab, he noticed that instead of the typical orange rust his experiment was producing a rust so dark green it appeared almost black. His fear that he’d damaged the power supply wiring soon turned to curiosity when he saw that this new particle settled much faster than orange rust. Further testing revealed that Green Rust, which has a much larger particle size, settles in under an hour, a huge improvement over orange rust which takes several days to settle out.  If this discovery pans out, it could eliminate the need for a filter or coagulant in future ECAR prototype designs, further reducing costs for this potentially life-saving technology.

Berkeley students interested in studying water are lucky that we have on campus one of the few libraries in the country devoted to water: the nationally acclaimed Water Resources Center Archives (WRCA). Begun in 1958, WRCA’s one-of-a-kind collection is devoted to recording water development in California and throughout the arid West.  Because struggles over water have shaped so much of the state’s history and landscapes, it is hard to underestimate the significance of these materials. The libraries rich holdings include technical reports from sources such as local water agencies, consultants and engineering firms; specialized newsletters; maps; videos; and an extensive photograph collection that captures the construction of California’s major water projects and much more.

WRCA pulls together a wide array of water-related materials that are difficult to find elsewhere, let alone all in one place. Their ongoing efforts to collect and preserve water-related information have recently focused on capturing electronic data, as more reports, meeting minutes, and information appear only online.  Using web archiving tools, librarians are able to save and make searchable otherwise ephemeral data from websites, for example those run by water and irrigation districts, or federal, state, and local water agencies.

For those interested in exploring further, WRCA’s collection can be accessed through both Melvyl and Oskicat. One element of this collection that Head Librarian Linda Vida suspects is underutilized by graduate students are WRCA’s archival materials, which must be searched with finding aids.  Fortunately, these finding aids are now available online. WRCA also participates in the eScholarship Publishing program, which makes the full-text of scholarly publications available online for free. The recordings of the California Colloquium on Water lectures are another online resource that students may find useful. WRCA also sends one student each semester on a Water Education Foundation tour. During these 2-3 day tours, you will learn more about state water issues and meet other water professionals. Join WRCA’s mailing list to find out how to be considered for this opportunity by sending an email to waterarc@library.berkeley.edu. To keep up-to-date on the latest WRCA news you can also follow them on Facebook.

Sadly, the future of the WRCA on Berkeley’s campus is in jeopardy. Although WRCA is located at Berkeley, it is funded by the Office of the President for the benefit of the UC system as a whole. In October, Dan Dooley, the Vice President of the Division of Agriculture and Natural Resources (ANR) announced that to save money ANR would seek a UC campus to adopt the library and its $230,000 annual cost.  Berkeley risks losing this unique resource. This would be a serious loss to the campus community and water professionals who regularly consult WRCA in their work. WRCA is truly a public resource; a UC library card is not needed to check out or use their materials, and the library would like to maintain its liberal lending policy. For now, the library will remain open in its current location (410 O’Brien Hall) until June 30, 2010. If you’re interested in supporting WRCA’s bid to stay at Berkeley, you can send an email to Linda Vida (lvida@library.berkeley.edu) expressing your interest in helping their cause. WRCA librarians are compiling a list of people who are willing to take part in a letter writing campaign and will send out an email to the group once they’ve decided on a course of action. However things end up – and WRCA is definitely a campus resource worth fighting for – I highly recommend that you stop by WRCA, either to become acquainted with their collection or to enjoy a peaceful place to study.

Research highlights: Water

Photo by Lee Otis

This week we launch our second installment in “research highlights.” In October, we featured fire. Now, in December, as we wait for the next winter storm to sweep across the Bay Area, we turn our attention to water.

Water makes a compelling research topic because it is fundamental to life and so central to the way we live. Many believe that the management and distribution of the world’s water supply will be the critical environmental challenge of the twenty-first century. Already more than a billion people lack clean water to drink and for basic sanitation. And because many of climate change’s impacts will be related to water—e.g., melting glaciers and more severe droughts—additional changes to the availability and quality of the earth’s water resources are expected. While some of these concerns may seem abstract from the relative security of Berkeley’s campus, floods, droughts, tsunamis, and hurricanes, repeatedly remind of us water’s tremendous power to reshape human lives and challenge human institutions. Not surprisingly, water has gripped the imaginations of authors, artists, chemists, designers, historians, lawyers, and policy makers to name just a few.

With just two weeks left in the semester, it has been hard to find people with the free time to talk about their research. Nevertheless, until the end of the semester, we’ll be featuring Berkeley graduate students’ water-related research projects along with relevant campus resources. Up first, the Water Resources Center Archives.

Fire research pt. 4: Indigenous land management

Quiroste Valley

Quiroste Valley, Año Nuevo State Reserve

Through their use of fire, Native Californians once played a pivotal role in maintaining a patchwork of diverse habitats throughout the state.  Some of California’s most iconic landscapes, including the open meadows of Yosemite Valley and the rolling coastal prairie surrounding the Golden Gate, are attributed to the land management practices of local tribal people. Fire was the most important of the many tools Native Californians used to manage local ecosystems for food, medicine, and raw materials. Recently there’s been a surge of scholarly interest in the significance of Indian burning in order to reconstruct particular burning practices Native people employed, practices largely disrupted by European colonization. As early as 1793, colonial officials set out to eliminate Indian fires at the same time exotic plants and animals changed California’s fire environment. Taken together the drastic social and environmental changes of the last two centuries have clouded our understanding of the role that Indian burning played in California.

An exciting collaborative research project at Año Nuevo State Reserve is using an interdisciplinary ecological and archaeological approach to piece together the most complete picture of indigenous land management and its effects in California to date. This research is the joint effort of the Amah Mutsun Ohlone, the California Department of Parks and Recreation, the San Francisco Estuary Institute, and researchers at UC Berkeley and UC Santa Cruz.

As part of this project, Chuck Striplen, a graduate student in Environmental Science, Policy & Management and an Amah Mutsun tribal member, is using fire scars to reconstruct the fire history of a prominent historic Ohlone village site and the surrounding watershed. Fire scars indicate when fires occurred, and can often reveal information about the seasonality of fires. By analyzing fire scars from trees throughout this watershed, Chuck can put together the fire regime for this area over time. Chuck’s research is being conducted in conjunction with the Fire Science Laboratory at UC Berkeley and his findings will address the seasonality, extent, severity, and frequency of fires in the Quiroste Valley. Combined with archaeological information about what food and materials the Amah Mutsun Ohlone tribe used in the past and historical landscape data from maps and photographs, Chuck’s research will shed new light on how California Indians managed and shaped their environment. In addition to its academic significance, this research will be useful to land managers throughout the state. One positive outcome of this collaboration has been the creation of California’s newest State Cultural Preserve – Quiroste Valley, encompassing the entire viewshed of the historic village – which also includes mechanisms by which the Tribe can eventually co-manage the Preserve with State Parks.

Fire research pt. 3: Fire in space

Fittingly on a day when NASA successfully fired a rocket into the moon, we turn our attention to space. More specifically, we’ll be looking at fire safety in space, which is the focus of Sonia Fereres’s research. NASA’s Constellation Program aims to send people back to the moon, then to Mars and beyond. Part of this program involves the creation of a new generation of spacecraft like the Orion crew exploration vehicle. Unlike the Space Shuttles currently in operation, whose cabin environment mimics the atmospheric pressure and oxygen concentration of earth at sea level, the new vehicles are designed to have lower pressure cabin environments with increased oxygen concentrations. Raising oxygen concentrations increases the risk of fire, a phenomenon that poses unique challenges and dangers on board spacecraft.

That’s where Sonia’s research comes in. For her Ph.D. in Mechanical Engineering, she’s studying the flammability of different materials under these low pressure, high oxygen conditions. Flammability can be characterized several ways: ease of ignition, flame spread, and heat release rate, to name a few. Sonia studies the ease of ignition because the other dimensions of flammability only come into play once ignition has occurred, making it of paramount importance for fire safety.

To determine the fire risk posed by these extraterrestrial conditions while remaining firmly grounded in a Berkeley laboratory, Sonia runs experiments inside a special containment chamber, the Forced Ignition and Spread Test (FIST). There, she can manipulate ambient pressure and oxygen concentration in order to compare time to ignition and sample mass loss until ignition under various conditions. This research will help establish whether reduced pressure and enriched oxygen environments pose a higher fire risk than normal atmospheric conditions, a subject of considerable interest to NASA as it develops a space program for the twenty-first century.

Jason Burwen, a joint Master’s student in Public Policy and International and Area Studies, studies fire of a different sort—the fires that Sissali and Dagaare women of northern Ghana build daily to cook for their families.

Cookstoves_Demo

Hawa Issifu cooking on an improved stove

The wood-burning cookstoves used in northern Ghana are crucial elements in local food production and culture, but they also have health and environmental impacts that make them the target for international development interventions. Wood-burning stoves contribute to greenhouse gas emissions and release particulate matter that is harmful to human health. Globally, exposure to indoor air pollution is one of the leading environmental causes of disease and one that disproportionately affects women and children. Jason was drawn to working on cookstoves because they sit at the nexus of so many different development issues: energy, environment, health, poverty, and gender. More generally, cookstoves have attracted the attention of researchers and practitioners alike because small improvements in cookstove technology and use promise to have meaningful impacts on people’s lives.

Cookstoves_Training

A training on stove construction in Gorima

Jason’s research is part of a collaboration between UC Berkeley, the Ghanaian Council for Scientific and Industrial Research, and Plan Ghana that aims to share both technology and knowledge with the women in these rural communities. Together they’re distributing improved cookstoves and providing training on how to build and use these stoves. The new stoves are designed to make a better fire and to vent smoke away from the user. In a better fire the combustion of the wood is more complete, which results in a more efficient use of the energy stored in the wood and the release of less particulate matter.

Within this context, Jason is evaluating the impacts of the improved cookstoves by quantifying their health and environmental impacts using a randomized-control field trial. In the field, he measured how much wood was burned and how much carbon monoxide women were exposed to while cooking a traditional meal. He is also using temperature sensors to record stove usage patterns. With this information and data from household surveys, Jason hopes to estimate the longitudinal impact of improved stoves on women and children’s health as well as their impact on the environment. At a larger scale, Jason is interested in the fate of wood in this system that does not get burned for cooking and what role training and education plays in the adoption of new technology.  While he and his fantastic undergraduate research assistant, Richard Tam, begin the work of assembling and analyzing a substantial data set on stove and fuel usage, Jason is still appreciating the practical education in international development he gained through his experience implementing trainings in stove construction and use for hundreds of women across several north Ghanaian villages.

Fire research pt. 1: Embers & ignition

Each summer and fall, California burns. Many of California’s plant communities may have evolved to live with fire, but most of the state’s human communities are not especially fire-adapted. Engineering Master’s student Sarah Scott is investigating how wildland fires spread in the hopes that this knowledge can be put to use planning better wildland-urban interfaces and preventing some of the tragedies fires cause annually.

ember_tunnel

Ember tunnel

Sarah’s research examines how an ember or hot particle ignites pine needles, grasses, and other materials common in wildlands. Using a specialized small-scale wind tunnel, she tests how the size and temperature of embers and hot particles, the type of fuel bed, and wind velocity affect ignition. Above the wind tunnel, an automated lighter heats particles with a flame before dropping them onto the sample fuel material (e.g., pine needles) below. A video camera captures the interaction between these heated particles and the fuel bed, while thermocouples record its temperature.

Ultimately, the information Sarah’s research generates can be incorporated into models for predicting fire development and spread at the landscape scale. Research that begins with the interaction between a single ember and a bed of grass may someday influence the how residential developments interface with the forests, shrublands, and grasslands next door.
