Towards Smallholder Food And Water Security: Climate Variability In The Context Of Multiple Livelihood Hazards In Nicaragua, Christopher M. Bacon, William A. Sundstrom, Iris Stewart-Frey, Edwin P. Maurer, Lisa C. Kelley

Environmental Studies and Sciences

Climate variability and change affect both food and water security, as do other hazards, such as shifting food prices, plant pathogens, and political economic changes. Although household food and water insecurity affect billions, most studies analyze them separately. This article develops a relational approach to explaining household access to food and water in a multi-hazard context. We identify pathways linking hazards to livelihood vulnerability and assess the relative importance of climate-related hazards. Analyzing longitudinal data collected from two surveys of the same 311 smallholder households in northern Nicaragua, conducted in 2014 and again in 2017, we find that peak seasons …

Toward A Feminist Political Ecology Of Household Food And Water Security During Drought In Northern Nicaragua, Christopher M. Bacon, Lisa C. Kelley, Iris Stewart-Frey

Environmental Studies and Sciences

Few studies assess the relationship between food and water access, despite global concerns about people’s inability to maintain access to both food and water. We conducted a mixed-methods comparative case study in northern Nicaragua, with smallholders from two neighboring communities that differed in water availability and institutional strength, using a feminist political ecology framework and food and water security definitions that focus on access, availability, use, and stability. We adopted a participatory approach that included: a sex-disaggregated survey in 2016; interviews, participant observation, and community-based water quality testing from 2014 to 2019; and analysis of a severe drought that occurred …

Agroecology And Participatory Action Research For Food And Water Justice In Central America, Christopher M. Bacon

Environmental Studies and Sciences

I remember driving with local community leaders into northern Nicaragua’s mountains to meet with organized farmers as we continued a long-term relationship that sought to explain and construct strategic responses to drought and an El Niño event in 2016. The Famine Early Warning Systems Network warned that this area, and much of Central America, was experiencing a stage three food crisis characterized by severe food insecurity coping responses, such as skipping meals and selling assets. Yet here we found farmers that had organized themselves into a cooperative and invested not only in organic coffee for export, but also in corn …

On-Farm Food Loss In Northern And Central California: Results Of Field Survey Measurementsauthor Links Open Overlay Panel, Gregory A. Baker, Leslie C. Gray, Michael J. Harwood, Travis J. Osland, Jean Baptiste C. Tooley

Environmental Studies and Sciences

Prevailing estimates of food loss at the farm level are sparse and often reliant upon grower surveys. A more comprehensive review of food loss at the farm level using field surveys is required to gain an adequate understanding of the depth of this issue. This paper details the results of 123 in-field surveys and 18 in-depth interviews of 20 different, hand-harvested field crops performed largely on midsize to large conventional farms in northern and central California. We also provide estimates of the percentage of fields that go unharvested, commonly known as walk-by fields. The results show that food loss is …

Engaged Communication Scholarship For Environmental Justice: A Research Agenda, Chad Raphael

Communication

As a discipline of crisis and care, environmental communication needs to address questions of environmental justice. This article argues that the most appropriate approach to studying environmental justice communication is engaged scholarship, in which academics collaborate with community partners, advocates, and others to conduct research. The article reviews prior engaged communication scholarship on environmental justice, and proposes four streams of future research, focused on news and information, deliberation and participation, campaigns and movements, and education and literacy.

Native Americans, The California Missions, And The Long-Term Effects Of Colonization, Jasminder Bains

Library Diversity Fellows Publications

This historical essay re-centers the narrative about the California Mission period on the Native American perspective. Areas of focus include the Ohlone, the ecological changes to Santa Clara Valley, cultural hegemony, oppression, and modern-day connections.

Engaged Scholarship For Environmental Justice: A Guide, Chad Raphael

Communication

This guide was written for distribution at the Environmental Justice and the Common Good Conference, hosted by Santa Clara University’s Ignatian Center for Jesuit Education in May 2019. The conference convened representatives from Jesuit and other universities with a broad range of community organizations to strengthen our common understanding and advancement of community-engaged scholarship for environmental justice (EJ). Given its immediate audience, the guide focuses primarily on the U.S. context, although it also discusses the major global causes and impacts of EJ, and how Americans have been inspired by engaged scholars around the world, from whom we have much to …

Creating Low-Carbon Communities: Evaluating The Role Of Individual Agency And Systemic Inequality In San Jose, Ca, Erin Jessica Ronald

Library Undergraduate Research Award

Following a scholarly need to test compelling community level sociodemographic representations of environmental behaviors and outcomes, a sequential mixed method approach was used to evaluate the connections of human agency and systemic inequalities with carbon footprints. Statistical analyses of the 2016 SDG San Jose Dashboard data of city blocks and 2009 - 2013 ACS survey data were supplemented with interviews with eight climate action-oriented community engagement professionals in the South Bay. Boundary limiting socioeconomic conditions for systemic inequalities and human agency, dimensions of Gidden’s Structuration model, were specified. Partially supporting structural inequality theories, socioeconomic resources, primarily, and to a lesser …

Residential Zoning And Near-Roadway Air Pollution: An Analysis Of Los Angeles, C. J. Gabbe

Environmental Studies and Sciences

Air pollution from motor vehicles harms the health of those who live near freeways and other high-traffic roads. Land use regulations may permit, prohibit, or impose special conditions on housing near major roadways. This paper answers two questions: First, how is residential development near major roadways regulated? Second, how common are zoning changes near major roadways, and what factors explain these changes? This paper compares the zoning designations of near-roadway parcels with others in the city, and uses two sets of logistic regression models to analyze near-roadway zoning. The results show that residential development is permitted on most near-roadway parcels, …

Climate Response To The 8.2 Ka Event In Coastal California, Jessica L. Oster, Warren D. Sharp, Aaron K. Covey, Jansen Gibson, Bruce Rogers, Hari T. Mix

Environmental Studies and Sciences

A fast-growing stalagmite from the central California coast provides a high-resolution record of climatic changes synchronous with global perturbations resulting from the catastrophic drainage of proglacial Lake Agassiz at ca. 8.2 ka. High frequency, large amplitude variations in carbon isotopes during the 8.2 ka event, coupled with pulsed increases in phosphorus concentrations, indicate more frequent or intense winter storms on the California coast. Decreased magnesium-calcium ratios point toward a sustained increase in effective moisture during the event, however the magnitude of change in Mg/Ca suggests this event was not as pronounced on the western North American coast as anomalies seen …

Why Are Regulations Changed? A Parcel Analysis Of Upzoning In Los Angeles, C. J. Gabbe

Environmental Studies and Sciences

Planners, officials, and neighborhood groups often debate zoning changes, yet there is little empirical evidence explaining why zoning and other land use regulations are changed. I use logistic regression models to examine density-enabling rezoning (“upzoning”) in Los Angeles. I find that upzoning occurs where there are development opportunities combined with limited political resistance. Upzoning is most likely on well-located parcels zoned for low-intensity, nonresidential uses. Meanwhile, homeowners—and particularly homeowners with access to valuable amenities—are associated with regulatory stasis. I conclude by recommending strategies for addressing homeowners’ concerns about higher density housing.

Employment Proximity And Outcomes For Moving Toopportunity Families, Michael C. Lens, C. J. Gabbe

Environmental Studies and Sciences

The Moving to Opportunity for Fair Housing Demonstration (MTO) randomly assigned housing vouchers to public housing residents in an experimental test of the effect of neighborhood and location on household outcomes. In terms of adult employment outcomes, the 2 treatment groups did not significantly differ from the control group. We use MTO data to examine whether spatial proximity to jobs and job growth explains this lack of treatment effect. We first estimate differences in access to jobs and job growth for the 3 MTO groups. We then use 2-stage least squares models to test relationships between employment accessibility and 2 …

Hidden Costs And Deadweight Losses: Bundled Parking Andresidential Rents In The Metropolitan United States, C. J. Gabbe, Gregory Pierce

Environmental Studies and Sciences

There is a major housing affordability crisis in many American metropolitan areas, particularly for renters. Minimum parking requirements in municipal zoning codes drive up the price of housing, and thus represent an important potential for reform for local policymakers. The relationship between parking and housing prices, however, remains poorly understood. We use national American Housing Survey data and hedonic regression techniques to investigate this relationship. We find that the cost of garage parking to renter households is approximately $1,700 per year, or an additional 17% of a housing unit’s rent. In addition to the magnitude of this transport cost burden …

Turning On The Lights: Transcending Energy Poverty Through The Power Of Women Entrepreneurs, Leslie C. Gray, Alaina Boyle, Victoria Yu

Miller Center Fellowship

Solar lanterns offer affordable, high-quality lighting in developing countries. A number of organizations, including social enterprises, make solar lanterns available to rural households as an alternative to candles or kerosene lamps. One of the most successful of these organizations is Solar Sister.

Solar Sister, a social enterprise operating in Tanzania, Uganda, and Nigeria, is dedicated to eradicating energy poverty through the economic empowerment of women. In addition to economically empowering its women entrepreneurs, the business model of Solar Sister also cultivates sales networks built on trust in last-mile distribution methods.

While Solar Sister has previously conducted research regarding its many …

Change The Game, John S. Farnsworth

Environmental Studies and Sciences

Not only was it a wild idea, it was someone else’s wild idea.

Having spent the three previous summers working feverishly on a book, I’d decided that I was due for a more restful interlude between spring and fall quarters. My summer was to be heavy on contemplation as I scratched together a prospectus for a new book. There was to be ample time for grant writing. In my spare time I would work on a sabbatical proposal. There was the pile of books I was eager to get to, heavy on obscure nature writers.

Then came an email from …

Looking Through The Lens Of Size: Land Use Regulations And Micro-Apartments Insan Francisco, C. J. Gabbe

Environmental Studies and Sciences

Small studio apartments, or micro-apartments, represent a market response to high housing costs in several major American cities. San Francisco, California, is one of the nation’s most expensive housing markets and the location of an innovative pilot microapartment policy. The literature on regulatory barriers to affordable housing has yet to pay much attention to minimum unit-size requirements. This article uses two prototype buildings to illustrate regulatory barriers to smaller units, including minimum parking standards in some parts of the city, outdoor open-space and indoor common-space provisions, unit-mix stipulations, and inclusionary zoning requirements. I recommend that cities review their codes through …

Women And Gender: Useful Categories Of Analysis In Environmental History, Nancy Unger

History

In 1990, Carolyn Merchant proposed, in a roundtable discussion published in The Journal of American History, that gender perspective be added to the conceptual frameworks in environmental history. 1 Her proposal was expanded by Melissa Leach and Cathy Green in the British journal Environment and History in 1997. 2 The ongoing need for broader and more thoughtful and analytic investigations into the powerful relationship between gender and the environment throughout history was confirmed in 2001 by Richard White and Vera Norwood in "Environmental History, Retrospect and Prospect," a forum in the Pacific Historical Review. Both Norwood, in her provocative contribution …

Aridification Of Central Asia And Uplift Of The Altai And Hangay Mountains, Mongolia: Stable Isotope Evidence, Jeremy K. Caves, Derek J. Sjostrom, Hari T. Mix, Matthew J. Winnick, C. Page Chamberlain

Environmental Studies and Sciences

Central Asia has become increasingly arid during the Cenozoic, though the mechanisms behind this aridification remain unresolved. Much attention has focused on the influence and uplift history of the Tibetan Plateau. However, the role of ranges linked to India-Asia convergence but well north of the Plateau—including the Altai, Sayan, and Hangay—in creating the arid climate of Central Asia is poorly understood. Today, these ranges create a prominent rain shadow, effectively separating the boreal forest to the north from the deserts of Central Asia. To explore the role of these mountains in modifying climate since the late Eocene, we measured carbon …

The Impact Of Neogene Grassland Expansion And Aridification On The Isotopic Composition Of Continental Precipitation, Charles P. Chamberlain, Matthew J. Winnick, Hari T. Mix, Samuel D. Chamberlain, Katharine Maher

Environmental Studies and Sciences

The late Cenozoic was a time of global cooling, increased aridity, and expansion of grasslands. In the last two decades numerous records of oxygen isotopes have been collected to assess plant ecological changes, understand terrestrial paleoclimate, and to determine the surface history of mountain belts. The δ¹⁸(O) values of these records, in general, increase from the mid-Miocene to the Recent. We suggest that these records record an increase in aridity and expansion of grasslands in midlatitude continental regions. We use a nondimensional isotopic vapor transport model coupled with a soil water isotope model to evaluate the role of vapor recycling …

Participatory Action And Drought As A Symbolic Context: The Case Of Aldama Chihuahua, Mexico, Sara Soledad Garcia

Teacher Education

This paper presents a field-based project and a theoretical framework for work with an Action Research paradigm. The complexities of process are illustrated and synthesized in two theoretical models. The design of the study required constant change in the focus of projects as a result of the action produced from genuine involvement. As a result a working template of the execution of the action research projects involving multiple educational institutions was generated by bi-national collaborations. Participants were ecological researchers and schoolteachers, actively engaged in schools and in the education of the community at-large on the effects of drought in their …

An Invitation For Engagement: Assigning And Assessing Field Notes To Promote Deeper Levels Of Observation, John S. Farnsworth, Lyn Baldwin, Michelle Bezanson

Environmental Studies and Sciences

This paper explores current practices for teaching the discipline of keeping field notes within academic natural history courses. We investigate how journal projects can be structured to promote engagement with the natural world while emphasizing the importance of recording accurate and honest observations. Particular attention is paid herein to the assignment of field notes, and to the process of assessing the results of these assignments. Our discussion includes results from an informal survey of best practices among colleagues representing numerous natural history disciplines.

Food Sovereignty: An Alternative Paradigm For Poverty Reduction And Biodiversity Conservation In Latin America, M Jahi Chappell, Hannah Wittman, Christopher M. Bacon, Bruce G. Ferguson, Luis García Barrios, Raúl García Barrios, Daniel Jaffee, Jefferson Lima, V. Ernesto Méndez,, Helda Morales, Lorena Soto-Pinto, John Vandermeer, Ivette Perfecto

Environmental Studies and Sciences

Strong feedback between global biodiversity loss and persistent, extreme rural poverty are major challenges in the face of concurrent food, energy, and environmental crises. This paper examines the role of industrial agricultural intensification and market integration as exogenous socio-ecological drivers of biodiversity loss and poverty traps in Latin America. We then analyze the potential of a food sovereignty framework, based on protecting the viability of a diverse agroecological matrix while supporting rural livelihoods and global food production. We review several successful examples of this approach, including ecological land reform in Brazil, agroforestry, milpa, and the uses of wild varieties in …

Introduction To Empowered Partnerships: Community-Based Participatory Action Research For Environmental Justice, Christopher M. Bacon, Saneta Devuono-Powell, Mary Louise Frampton, Tony Lopresti, Camille Pannu

Environmental Studies and Sciences

This article introduces a special section on empowered partnerships that deepens a dialogue initiated during the 2010 symposium titled EmPowered Partnerships: Community-Based Participatory Action Research for Environmental Justice. The articles in this section will be divided between issues 1 and 2 of the Journal. After briefly reviewing the definitions and the steps associated with community-based participatory action research (CBPAR), we identify the synergies connecting the underlying principles and values of the environmental justice (EJ) movement and CBPAR. The principles-based comparison is part of an ongoing effort to craft a framework that produces research partnerships that are simultaneously more responsive to …

Early Cenozoic Evolution Of Topography, Climate, And Stable Isotopes In Precipitation In The North American Cordillera, Ran Feng, Christopher J. Poulsen, Martin Werner, C. Page Chamberlain, Hari T. Mix, Andreas Mulch

Environmental Studies and Sciences

Paleoelevation reconstructions of the North American Cordillera inferred from the oxygen (δ¹⁸O) and hydrogen (δD) isotope ratios of terrestrial paleoclimate proxy materials (soils, ashes, lake sediments) suggest rapid north-to-south migration of topography in the early Cenozoic (pre-49 Ma to 28 Ma). The validation of this reconstruction relies on an accurate understanding of the δ¹⁸Op and the associated regional climate change in response to the uplift of the western North America. Here we study this response using a global climate model (GCM) with explicit δ¹⁸Op diagnostics (ECHAM5-wiso) focusing on the isotopic effects of different types of precipitation, vapor mixing, recycling and …

Quality Revolutions, Solidarity Networks, And Sustainability Innovations: Following Fair Trade Coffee From Nicaragua To California, Christopher M. Bacon

Environmental Studies and Sciences

Nicaraguan smallholder cooperative leaders working in partnership with a California-based small-scale roasting company pioneered an alternative approach to confronting the post-1999 coffee crisis. They built coffee tasting laboratories and integrated grassroots organizing efforts to create a national smallholder cooperative association that dramatically improved the quality, consistency, and prices from of the coffee they exported. Cooperative leaders used this development project to gain a more significant share of political economic power in a domestic coffee industry historically dominated by colonial powers, and corporate and domestic elites. This alliance between the artisanal small-scale roasting companies and cooperative leaders also proved that smallholders …

Hetch Hetchy Redux: An Effort To Turn Back The Environmental Clock, Nancy Unger

History

If San Francisco voters pass Measure F on November 6, the city will conduct an $8 million study on the feasibility, costs, and benefits of draining the 300-foot deep reservoir created by the O’Shaughnessy Dam in 1923. The measure’s proponents see it as a first step in restoring Hetch Hetchy Valley, sister valley to Yosemite, to its natural state. That the measure is even on the ballot is a significant indication of the shift in attitudes towards the ongoing conflict between nature preservation and traditional notions of progress.

Introduction: Sex, Sexuality, And Gender As Useful Categories In Environmental History, Nancy Unger

History

This book is an effort to explain these kinds of extreme gendered divisions and to offer an enriched understanding of the powerful interplay between environment and sex, sexuality, and gender. The synergy produced by that interplay has been significant throughout American history, but it cannot be adequately understood and appreciated as long as those fields are discussed as discrete entities. The fields of gender and environment are growing, but scholars have seldom joined them together in analysis or heeded historian Carolyn Merchant's call that a gendered perspective be added to conceptual frameworks in environmental history.5 They have not offered a …

Critical Reflections On Experiential Learning For Food Justice, Leslie C. Gray, Joanna Johnson, Nicole Latham, Michelle Tang, Ann Thomas

Environmental Studies and Sciences

This essay will reflect on Santa Clara University's (SCU) forays into experiential learning around food justice through the Bronco Urban Gardens (BUG) program. BUG works with urban schools and a community center in San José, California, using a garden-based education approach. This program emerged out of our student garden, The Forge. University student farms and gardens provide opportunities for students to learn how to grow, manage, and market food. At Santa Clara University, our half-acre (0.2 hectare) garden plays that role. However, because of our institution's commitment to social justice and a strong network of community partners, our campus garden …

The Cenozoic Climatic And Topographic Evolution Of The Western North American Cordillera, C. Page Chamberlain, Hari T. Mix, Andreas Mulch, Michael T. Hren, Malinda L. Kent-Corson, Steven J. Davis, Travis Horton, Stephan A. Graham

Environmental Studies and Sciences

Herein we present oxygen isotope records from Cretaceous to Recent terrestrial sediments in the western North American Cordillera. The purpose of this analysis is to use oxygen isotope records to understand the coupled surface elevation and climate histories of this region through the Cenozoic. To do this we constructed δ¹⁸(O) maps of surface waters for time intervals that trace the development of topography of western North America. These maps are based on 4861 oxygen isotope analyses from both published (4478) and new (383) data. We determined the δ¹⁸(O) values of surface waters using paleotemperatures derived previously from floral assemblages and …

Diversified Farming Systems: An Agroecological, Systems-Based Alternative To Modern Industrial Agriculture, Claire Kremen, Alastair Iles, Christopher M. Bacon

Environmental Studies and Sciences

This Special Issue on Diversified Farming Systems is motivated by a desire to understand how agriculture designed according to whole systems, agroecological principles can contribute to creating a more sustainable, socially just, and secure global food system. We first define Diversified Farming Systems (DFS) as farming practices and landscapes that intentionally include functional biodiversity at multiple spatial and/or temporal scales in order to maintain ecosystem services that provide critical inputs to agriculture, such as soil fertility, pest and disease control, water use efficiency, and pollination. We explore to what extent DFS overlap or are differentiated from existing concepts such as …
