How hot is too hot for farm workers in the Imperial Valley?

Friday, March 1, 2024
3:30-4:30 pm
Storm Hall 320

Dr. Sagar Parajuli
Researcher, Department of Geography
San Diego State University 

Abstract: The Imperial Valley (IV) is a key agricultural area in Southern California, producing more than 80% of winter fruits and vegetables consumed in the US. Unfortunately, the farm workers in the IV region are often exposed to high heat making them prone to heat-related illnesses. In this talk, I will present a regional climate model centered over the Salton Sea-Imperial Valley region and illustrate how it can be used to determine heat stress experienced by farmworkers. The high-resolution model outputs can be used to calculate the standard metric of heat exposure, the Wet Bulb Globe Temperature (WBGT), enabling us to assess heat exposure at a specific time and location in different crop and land use environments. The results from this research will help formulate evidence-based labor and environmental policies in this important agricultural region.

About: Dr. Sagar Parajuli is a researcher with expertise in regional climate and air-quality modeling. He is currently working on a project called Rural Heat Island at San Diego State University, Geography Department, which aims to understand the impact of heat stress on farmers around the Salton Sea and Imperial Valley region. He obtained his PhD in Geosciences from The University of Texas at Austin, Master’s degree in Water and Environmental Engineering from the Masdar Institute of Science and Technology, UAE, and Bachelor’s degree in Civil Engineering from Institute of Engineering, Nepal. He is currently also serving as an editorial board member of the Nature portfolio journal Communications Earth & Environment.

Mapping Tomorrow’s Habitats: Predicting Plant Vulnerability in a Changing World

Brooke Rose, Ph.D.
Postdoctoral Research Scholar, SDSU Research Foundation

As climates and landscapes continue to change due to human activity, some plants will be more susceptible to habitat loss and potential extinction than others. Using decades of species occurrence records and predictive spatial modeling, my research explores what makes some species more vulnerable to future habitat loss than others. The findings from this work emphasize that species’ biology and geography interact to shape their vulnerability, or resilience, to anthropogenic change. I will also share how my research offers a framework for assessing plant vulnerability to environmental change in other threatened regions, highlighting opportunities for undergraduate research.

Brooke Rose is a postdoctoral researcher at SDSU in Janet Franklin’s Vegetation and Landscape Ecology lab. Her research explores plant vulnerability in the face of global change and how decisions made when forecasting vulnerability can influence conservation outcomes.

Uncertainties brought about by climate change have highlighted the interdependent relationship between water, energy, and food security. These three sectors have also been identified as areas of priorities for the achievement of sustainable development goals (SDGs). Research has shown that violence, uncertainty and unrest go hand in hand with food, water and energy scarcity globally. Establishing the link between the WEF Nexus and the SDGs is very crucial. This can be done by identifying the drivers behind this link as well as the corresponding responses. Outcomes of pilot projects and research done within the South African context are indicative of the need to emphasis the need to develop the WEF Nexus concept. This involves recognizing, understanding, and evaluating the linkages between related disciplines and sectors that will lead to efficient use of resources in the three sectors in a sustainable manner.

Assessing Spatiotemporal Vulnerability of COVID-19 in Singapore

Dr. Yi-Chen Wang
Associate Professor
Department of Geography
National University of Singapore

Friday, September 30
3:30pm to 4:30pm
Storm Hall 316

 

The coronavirus disease 2019 (COVID-19) has posed one of the greatest threats to global public health, causing substantial economic, social and political disruption. Geospatial networks with high centrality and transitivity, such as public transportations, leisure and recreational spaces, and the workplace, are locations more susceptible to COVID-19. In response to this epidemic, Singapore entered into an unprecedented lockdown in April 2020, locally coined as “Circuit Breaker,” to curb the virus from spreading. In this seminar, I will share our on-going project on assessing spatiotemporal vulnerability of COVID-19 in Singapore. I will first present a spatiotemporal integrated vulnerability model to characterize the variation of COVID-19 risk across space and time, incorporating social, built, platial and human movement features known to influence disease transmission. Analyses are conducted at the subzone level, the basic planning unit of Singapore. Then, I will share the survey of the project on individuals’ risk perception and behavioral change. Comparisons will be made for individual’s transition of places for different types of activities, such as work, getting food, and shopping, across the time periods of pre-COVID-19, during the Circuit Breaker, and early 2022. The survey will enhance the spatiotemporal model and inform the practicability of a neighborhood travel corridor.

Yi-Chen Wang is an Associate Professor at the Department of Geography, National University of Singapore. She also holds a Visiting Associate Professor position in the Department of Parasitology, Taipei Medical University, Taiwan since 2017. She received the PhD degree from the University at Buffalo, State University of New York. Her research area broadly covers land use land cover change and spatial health. Her recent work on the neglected tropical disease – liver fluke infection – investigates land use, human behavior, and social dynamics as risk factors of foodborne parasitic infection in the Lower Mekong River Basin. Her current work extends into health and environment in the urban setting, to apply geospatial technologies in examining the relationship between the neighborhood characteristics of the environments and infectious disease risk and distribution.

 

Remote Sensing of the Atmosphere using GNSS Signals

Dr. Pawel Hordyniec
Assistant Professor
Institute of Geodesy and Geoinformatics
Wroclaw University of Environmental and Life Sciences, Poland

Visiting Researcher
Scripps Institution of Oceanography
University of California San Diego

Friday, October 7
3:30pm to 4:30pm
Storm Hall 316

GNSS remote sensing techniques emerged from strictly geodetic applications for the purpose of accurate determination of positions and motions of points on the Earth’s surface. The atmosphere is one amongst a variety of factors limiting the performance of GNSS satellite positioning. In order to achieve centimeter-level accuracy, the delay induced by non-vacuum properties of the atmosphere needs to be estimated and removed from observations through modeling based on external meteorological information. It turned out that what is considered an error by the geodetic community can be also viewed as a valuable observation for meteorology, which opened a broad range of GNSS applications beyond the scope of the three pillars of geodesy: (1) geokinematics, (2) Earth’s rotation and (3) the gravity field. The atmospheric refraction can be measured with a GNSS receiver from various platforms, including ground-based geodetic networks, remote sensing satellites and research aircrafts. The limb sounding with the GNSS radio occultation (RO) technique is one of the most innovative measurement concepts that significantly contributed to atmospheric and climate sciences due to global coverage and its high vertical resolution. The retrieved atmospheric profiles are often referred to as anchor observations as they require no bias correction before being introduced to weather models. However, the process of converting observation data to model variables requires sophisticated methods to resolve the problem of data assimilation. In this talk, various applications of GNSS atmospheric remote sensing will be demonstrated and main scientific challenges will be outlined.

Pawel Hordyniec is an Assistant Professor at the Institute of Geodesy and Geoinformatics, Wroclaw University of Environmental and Life Sciences, Poland. He received the Ph.D. in satellite geodesy from WUELS, Poland in 2019. He has been working as an Assistant Professor with his home institution since 2015. During multiple stays in 2014-2017 as a Visiting Scholar he has been cooperating with researchers from National Central University, Taiwan and the National Space Organization, Taiwan on the development of algorithms for inverting GNSS radio occultation signals in the neutral atmosphere. In 2018-2020 he was a Research Fellow at RMIT University, Melbourne, Australia focusing on meteorological forecasting and climate analysis over the Australian and Antarctic regions with the use of GNSS remote sensing techniques. Currently, he is also a Visiting Researcher at the Scripps Institution of Oceanography, University of California San Diego, USA working towards improving the forecast skill of atmospheric river events that contribute to long duration heavy precipitation and flooding on the U.S. West Coast. His research interests are focused on applications of GNSS signals for the remote sensing of the atmosphere using spaceborne observations and ground-based measurements as well as numerical simulation methods for studying anomalous propagation of radio signals.

 

Hunger, Survivance, and Imaginative Futures: A Racial Analysis of the “Right to Food”

Dr. Adam M. Pine
Associate Professor of Geography
University of Minnesota Duluth

Friday, October 28
3:30pm to 4:30pm
Storm Hall 119

 

 

A “Better Foods Future” Talk

For the last half century, the “right to food” (RTF) framework has been promoted by the United Nations as an important policy framework to end hunger. However, the RTF assumes that countries view all of their population as worthy and deserving of food security. Given the legacy of racism in the United States, racialized minorities have not been viewed by the state as deservant of food security. Rather than work to support food security for all, the state instead has used its power to create two food systems, separate and unequal.

In this talk I explore how the U.S. government has used agricultural, food and nutrition, and urban planning policies to deny food to communities of color. Grounded in these historical patterns, I define equity principles to guide work on the racialized food system and I discuss six reparative public policies that will significantly decrease hunger and build political power in racialized communities: (a) repairing SNAP, (b) restoring food sovereignty, (c) revitalizing grocery stores, (d) reframing restaurants, (e) reconstituting food pantries, and (f) rebuilding communication sovereignty.

Dr. Pine is a human geographer (Ph.D. Rutgers) with teaching and research interests in urban policy, race, and the global food system. His principal research projects examine the relationship between white supremacy and US urban planning, the interconnections between housing precarity and food insecurity, and how anti-racist food activists are fighting to institute the right to food in the US.

 

Interdisciplinary and Data-Driven Approaches to Understanding Hydroclimatic Change

Dr. Morgan Levy
Assistant Professor
Scripps Institution of Oceanography
School of Global Policy and Strategy
University of California San Diego

Friday, November 4
3:30pm to 4:30pm
Storm Hall 316

 

Interactions between humans and water are mediated by complex social and physical dynamics. Thus, studying physical water systems in isolation is often not possible, and analysis of coupled systems can be challenging. For example, anthropogenic activities complicate the use of many traditional hydrologic modeling approaches by introducing non-stationarity and feedbacks. Considering this challenge, and the increased availability of spatiotemporal datasets, this talk will highlight the use of data-driven frameworks to understand interactions between geophysical water processes and human water use at multiple scales. Specifically, this talk will explore the impacts of hydroclimatic variability on inland and coastal surface water and groundwater availability in California. This research underscores the complexity and promise of using data-driven approaches to advance sustainable freshwater management and climate change adaptation.

Morgan Levy is an Assistant Professor in the Scripps Institution of Oceanography and the School of Global Policy and Strategy at the University of California, San Diego. She received a Ph.D. and M.S. in Energy and Resources, and a M.A. in Statistics from the University of California Berkeley. Her research focuses on understanding interactions between climate, terrestrial water systems, and environmental and human health at local to global scales. She uses methods from hydrology, ecohydrology, and applied statistics to do data-driven, policy-relevant research that connects climate to environmental and human health through water cycle processes.

 

Water Quality in Agricultural Landscapes: Ireland’s Agricultural Catchment Programme

The Lauren C. Post Memorial Lecture

Dr. Daniel Hawtree
Research Officer
Teagasc - Agricultural Catchment Programme

Adjunct Associate Professor
School of Biomolecular and Biomedical Science
University College Dublin, Ireland

Friday, November 18
3:30pm to 4:30pm
Storm Hall 316

The Agricultural Catchment Program (ACP) is a program initiated in Ireland in 2008 to monitor and assess the efficacy of measures put in place to protect water quality. To this end, a set of catchments were selected which represent a range of the most common agricultural and site conditions in Ireland, where long-term sampling stations could be established in cooperation with local farmers. At these sites, key variables are collected at high temporal resolution (e.g., 15-minutesampling time), which has provided a substantial trove of data on the hydrologic and nutrient dynamics in these catchments. Modelling efforts are now underway using these datasets to improve our capacity to predict future hydro-chemical fluxes under changing conditions, and to simulate alternate potential scenarios designed to meet Ireland’s obligations under EU regulations on agriculture and water quality. This seminar will provide an overview of the ACP and the current modelling work being undertaken, as well as touching on the other key components of the program (e.g., gaseous emissions, knowledge transfer, education).

Daniel Hawtree is a research officer at Teagasc (the Irish national body responsible for research, advisory, and training services to the agri-food industry) and an Adjunct Associate Professor at University College Dublin. At Teagasc, his research is focused on developing catchment models within the Agricultural Catchment Programme. Daniel is a native of San Diego and received both his BSc (Psychology) and MSc(Geography) at San Diego State University, which was then followed by a research internship at the European Commission Joint Research Centre (Ispra, Italy), and then a joint PhD split between Technische Universität Dresden and University of Padua. Since 2018, Daniel has been based in Ireland, where he carried out post-doctoral research at University College Dublin, before moving to Teagasc in 2021.

 

What Do We Lose When We Lose a Biome?

Dr. Bernardo A. Bastien-Olvera
Postdoctoral Scholar
Scripps Institution of Oceanography

Friday, January 27
3:30pm to 4:30pm
Storm Hall 316

 

The effects of climate change on natural systems will be substantial, widespread, and likely irreversible. Warmer temperatures and changing precipitation patterns have already contributed to forest dieback and pushed some species toward extinction. Natural systems contribute to human welfare both as an input to the production of consumption goods and through the provision of nonuse values (i.e., existence and bequest values). But because they are often unpriced, it can be difficult to constrain these benefits. Understanding how climate change effects on the natural capital stock affect human well-being, requires understanding not just the biophysical effects of climate change but also the particular role they play in supporting human welfare. This talk presents a framework to think about this question and applies it to global projections of climate-driven biome range shifts throughout this century.

Bernie is a geographer at the Scripps Institution of Oceanography researching how ecosystems react to climate change and how this will affect different societies worldwide. Interested in bridging process-based ecological dynamics and the multiple value systems that underlie human-nature relations to explore possible mitigation and adaptation strategies to climate change.

ChangeAerial

Friday, February 24
3:30pm to 4:30pm
Storm Hall 316

Aerial imaging is a useful tool for emergency management and response but poseschallenges in maximizing its effectiveness. The challenges include information quality, accuracy, and the timeliness of information delivery. This research associated with my doctoral dissertation builds upon the Remote Sensing Communication Model (RSCM) to configure an end-to-end time-sensitive remote-sensing-system based on uncrewed aerial systems (UAS) and machine-learning-based damage detection. UAS with different navigation capabilities were tested with repeat station imaging (RSI) and traditional imaging approaches at sites representing critical infrastructure at San Diego State University. Utilizing navigation corrections, the UAS flown with the RSI method was shown to have more accurate repeated navigation to camera stations and multi-date image pairs with the RSI method are shown to have lower image co-registration errors. A deep machine-learning model evaluated on two-date layer-stacked images detected damage (cracks) with a higher accuracy when applied to RSI images rather than those captured in a more ad hoc fashion. Customized deep-learning models were evaluated using the RSI images, with the best-performing model achieving 98.4% overall accuracy. These research findings document the potential for integration of UAS, RSI image capture and registration and deep learning damage detection models for post-hazard assessment of damage to critical infrastructure.

Dr. Andrew C. Loerch has a PhD in Geography from the SDSU and UCSB Joint Doctoral Program. His research has focused on remote sensing, software development and machine learning. His refereed publications include research in repeat station imaging for volumetric mapping, environmental monitoring and the use of artificial intelligence for detecting damage to critical infrastructure after disasters.

 

Projecting Extreme Droughts in Rapidly Changing Human-Water Systems Across the UK

Dr Gemma Coxon
Senior Lecturer in Hydrology
University of Bristol, England

Friday, March 10
3:30pm to 4:30pm
Storm Hall 316

A reliable water supply is often taken for granted in the UK. However, decreasing water supply from anthropogenic climate change, coupled with increasing water demand from a growing population are projected to lead to frequent water shortages across the UK by 2050. This seminar will present recent advances in national-scale drought modelling and our understanding of human influences on river flows using a unique dataset of spatially explicit, time-varying abstractions and discharges across the UK. It will also look ahead to discuss how we can ensure a resilient UK water supply for the future.

Dr. Gemma Coxon is a senior lecturer at the University of Bristol and a UKRI Future Leaders Fellow. Her research focuses on understanding and predicting floods and droughts in changing environments through the simulation of water systems from local to continental scales. Gemma and her team work closely with communities, water companies, and regulatory bodies across the UK, and are currently involved in projects on (1) delivering a £38M large-scale investment in flood and drought research infrastructure in the UK (2) informing the development of new water supply infrastructure and (3) projecting extreme droughts in rapidly changing human-water systems.

 

A Few Hundred Catchments Later – Lessons Learned From Modeling Large Catchment Samples

Dr. Jan Seibert
Professor of Geography
University of Zurich, Switzerland

Friday, March 17
3:30pm to 4:30pm
Storm Hall 316

Hydrological models have traditionally been applied to a few catchments, since the preparation of input data for a larger set of catchments is challenging. However, the availability of data sets with hydro-meteorological time series for large numbers of catchments has been a game changer. An example is the CAMELS data set with more than 600 U.S. catchments, for which basic data to run hydrological models has been made readily available. In recent studies, we used such data sets for bucket-type modeling of catchments in different regions. Here, I will discuss some of our main findings:

Simulation results can vary greatly between catchments, making large catchment samples a prerequisite for robust results. Results indicate that even when applied uncalibrated, simple bucket-type models can provide surprisingly good results for some catchments. This needs to be considered when we assess model performance. On the other hand, it can be challenging to improve simulations for ungauged catchments by regionalization as it is not apparent how to find the most suitable donor catchments.

Large samples of catchments also allow us to evaluate the value of different data types. A limited number of streamflow gaugings and other data types, such as stream levels, can be informative for streamflow simulations. We further extended this approach to our citizen science project, CrowdWater, and could demonstrate that data collected using so-called virtual staff gauges can be valuable for streamflow simulations.

Dr. Seibert’s main research interest is hydrological modeling at different scales in combination with experimental studies. Current research topics include the use of catchment models for land-use and climate change impact studies, runoff generation processes and topography, uncertainty analysis and risk assessment, the value of different types of data and opportunities for citizen science in hydrology. His research has so far resulted in more than 200 peer-reviewed journal publications.

 

Uses of Remote Sensing in Geology

Pacific Southwest Region
Spring Technical Meeting Plenary

This lecture will first provide an overview of geological problems that can be addressed with the use of remote sensing techniques. After this overview, we will focus on the catastrophic fluvial erosion taking place in the Coca River of Ecuador. On February 2, 2020 the largest waterfall in Ecuador, the San Rafael Waterfall with a height of ~150 m catastrophically collapsed, initiating a process of headward erosion that has wiped out one of the main roads in the eastern part of the country, tons of the main pipelines that transport crude oil from the field in the east to the ports on the Pacific coast, and threatens the largest hydropower plant in the country. The river is located in the Amazon foothills, with dense forest and cloud cover that hinders the use of many remote sensing techniques for its study. I will cover what we have been able to do to study this destructive natural process using drones and radar images, as well as what remains to be done to better describe this process.

Rafael Almeida is originally from Venezuela where he graduated from the Universidad de Los Andes as a Geological Engineer. He went on to do a master’s at Texas A & M University and a PhD at Columbia University. He worked as a researcher at the Earth Observatory of Singapore and then as faculty at Yachay Tech University in Ecuador. He has been part of the SDSU faculty at the Department of Geological Sciences for the last 2 years. He has worked on the geology of the western US, the Andes of Venezuela, Ecuador and Argentina, and the Himalaya system of Nepal and Bangladesh.

San Diego County Food Vision 2030 is a shared vision, plan, and movement for transforming our region’s food system over the next ten years. With three goals, ten objectives, and detailed strategies to inform policy, program, planning, and investment opportunities, Food Vision 2030 serves as a call to action and political compass as we work together toward a more equitable and resilient future for all.

Food Vision 2030 was published by the San Diego Food System Alliance in the Summer of 2021, and is the work of many people. 3,000 residents of San Diego County—a majority of whom have been deeply impacted by inequities—voiced their needs and aspirations for the food system and provided essential input on the Vision.

Please join Sona Desai to learn more about the San Diego County Food Vision 2030 planning process and how we can work together to imagine a food system that belongs to all of us.

Portraying Genocide through the Eyes of Children: The Troubled Geographies of Authenticity in Loung Ung’s “First They Killed My Father: A Daughter of Cambodia Remembers”

Dr. James A. Tyner
Professor of Geography
Kent State University

Friday, April 28
3:30pm to 4:30pm
Storm Hall 316

On April 17, 1975 soldiers of the Communist Party of Kampuchea (CPK), better known as the Khmer Rouge, entered Cambodia’s capital city of Phnom Penh. Within hours, heavily armed cadre—many of whom were themselves child-soldiers—began forcibly evacuating the city. For many men, women, and children—including a young girl named Luong Ung—this day marked the beginning of the Cambodian genocide. Such is the narrative of the 2017 Netflix film First They Killed My Father: A Daughter of Cambodia Remembers. Directed by Angelina Jolie, the film hews closely to Loung Ung’s 2000 autobiography of the same name. Written as an adult, Ung’s memoir received much acclaim and was a national bestseller. Indeed, while Ung’s narrative is among several memoirs published by Cambodian American survivors of the genocide, it has—with the exception of Ngor’s autobiography—received by far the most notoriety. To date, significant attention has focused both on Ung’s memoir and its cinematic sibling. In my presentation I contribute to conversations but do so in an attempt to place genocide studies in dialog with the subfield of children’s geographies. Ung’s filmic depiction of her everyday experiences of surviving genocide raises several concerns that coalesce around the struggle to articulate and authenticate the unimaginable. And yet, through the prism of Ung’s childhood eyes, a world of unthinkable horrors comes into focus and with it, an expository clarity that transcends a simple dichotomy of authentic and in-authentic.

Human-Watershed Interactions: from the Amazon to the US-Mexico Border

Dr. Trent Biggs, Professor of Geography, San Diego State University

Friday, September 17, 2021
3:30 pm to 4:30 pm
Zoom Link: https://sdsu.zoom.us/s/86108452784
Meeting ID: 861 0845 2784
Passcode: 92182

How do humans impact watersheds, including their water quantity and quality? What processes drive those impacts, and what are the consequences for humans and ecosystems? Finally, how can we combine remote sensing, modeling and field observations to understand human-watershed interactions? This talk will address these questions with examples from the Amazon and US-Mexico border, including a summary of work by SDSU faculty and students over the past 20+ years.

Trent W. Biggs’ research interests include the impacts of land use on hydrology, water quality, and sediment. Dr Biggs and his students use satellite imagery, fieldwork, and modeling to diagnose and analyze water-related problems that impact the environment and human welfare. His field locations include American Samoa, southern India, the Himalaya, and the US-Mexico border region. Most recently he and a team of students have analyzed the environmental consequences of urbanization on the US-Mexico border, with an emphasis on the origins of sediment that has damaged local estuaries.

 

The $16 Taco: Contested Geographies of Food, Ethnicity, and Gentrification

Dr. Pascale Joassart-Marcelli, Professor of Geography, San Diego State University

Friday, October 8, 2021
3:30 pm to 4:30 pm
Zoom link: https://SDSU.zoom.us/j/81442477084
Meeting ID: 814 4247 7084
Passcode: 92182

Barbacoa tacos, bibimbap, bánh mi, pupusas, and other “authentic ethnic” foods are drawing white, middle-class, and college-educated eaters into historically segregated neighborhoods where residents, mostly people of color and immigrants, have long struggled with limited food access. Does this signal the emergence of a more inclusive city?

The $16 Taco focuses on the role of food in transforming urban landscapes. Drawing on extensive field work in San Diego, Pascale Joassart-Marcelli documents the evolution of Barrio Logan, City Heights, and Southeastern San Diego’s foodscape away from serving the needs of long time minoritized residents to pleasing the tastes of wealthier and whiter newcomers. She shows how this trend—fueled by media attention and capitalized on by developers—contributes to gentrification and the displacement of the very people who have produced these foodscapes through self-reliance in the face of food apartheid. Her research illustrates how food can both emplace and displace immigrants, shedding light on the larger process of gentrification and the emotional, cultural, economic, and physical displacement it produces.

Pascale Joassart-Marcelli is Professor of Geography and Director of the interdisciplinary Food Studies and Urban Studies programs at San Diego State University where she has been teaching courses such as Geography of Cities, Geography of Food, Food Justice, Feeding the World, and Food, Place,and Culture. Her research focuses on the relationship between place, ethnicity, and food, including the role of food in creating just and sustainable cities for all. She has published over 50 peer-reviewed articles and book chapters, is the author of The $16 Taco: Contested Geographies of Food, Ethnicity, and Gentrification (2021) and the co-editor of Food and Place: A Critical Exploration (2018). Her research has been funded by the National Science Foundation and other private and public funding agencies.

 

Geography as Brick: Joyfully Fracturing the Ecology of Negligence and Inattention of the Cultural/Natural Resources Management Industrial Complex through Critical Geographies and Geo-Philosophies (with special focus on NHPA, NEPA, and CEQA)

Dr. Giorgio H. Curti, Co-Owner and Project Director, Cultural Geographics Consulting, LLC, Adjunct Professor and Lecturer, Department of Geography, SDSU

Passcode: 92182

Laws and regulations that guide environmental, heritage and cultural resource, and historic preservation in the United States—such as the National Historic Preservation Act (NHPA), National Environmental Policy Act (NEPA), and California Environmental Quality Act (CEQA)—ostensibly, in their stated intents and purposes, exist to serve the concerns, interests, and health and well-being of the multitude. Whatever the intentions of their promulgations, these laws have been found to be largely procedural by the courts. In practice, procedural implementations of these laws are overwhelmingly dominated by what can best be characterized as an ecology of governmental negligence and professional ultracrepidarian gatekeeping. This dominant and dominating symbiosis of carelessness and inattention defines the cultural/natural resources management industrial complex and often renders any semblance of compliance to empty and inattentive processes of hollow box-checking and limited disciplinary (mis)interpretations. This, in turn, works as regulatory capture through horizontal means. The dire effects on integral material, embodied, and relational capacities of communities and environments—particularly Native communities and their traditional cultural places and landscapes—are at best treated as matters that can be “mitigated” by so-called “subject matter experts” and at worst (and as is most common) realities to ignore, deflect, neglect or even actively veil, bury, and silence. This talk explores how spectrums and bricks of attentive geographical thought and practice—particularly those advanced by critical geographies (broadly understood) and geo-philosophies—offer pragmatic, inclusive, collaborative, corrective, and productive ways of joyfully fracturing and creatively re-fashioning circuits of the procedures that guide NHPA, NEPA, and CEQA compliance—to and for the benefits of the multitude.

Giorgio Hadi Curti is a socio-cultural geographer and critical ethnographer who works at the intersections of cultural and natural resources laws and mandates, traditional and local knowledges and sciences, and the collaborative development and implementation of land and water stewardship and management strategies guided and defined by Native and traditional communities and associated human-environment relationships, cosmologies, and worldview and value systems. Giorgio received his PhD in 2010 from the San Diego State University-University of California, Santa Barbara Geography Joint Doctoral Program. In 2016, Giorgio and friend and fellow SDSU-UCSB Joint Doctoral alum, Christopher Moreno, founded Cultural Geographics Consulting (CGC), a minority-owned small business that pursues ontological and epistemic justice in its dedicated mission to help create a world where historically and geographically marginalized peoples are empowered to define and direct their own futures. In addition to his work with CGC, Giorgio serves as Adjunct Professor and Lecturer in the SDSU Department of Geography, and as a Research Associate with the Young People’s Environments, Society and Space Research Center.

 

When All Models Are Wrong: A Recipe for Spatial Sensitivity Analysis

Dr. Seda Şalap-Ayça, Lecturer of Geosciences, University of Massachusetts Amherst

Friday, November 12, 2021
3:30 pm to 4:30 pm

Passcode: 92182

Descriptive and predictive spatial models are potentially important tools in aiding decision-making, providing that the reliability of their results is accounted for, explained, and properly communicated to model users. However, all process representations in spatial models are subject to uncertainty. Therefore, the question becomes how to understand the unknown (uncertainty) of the unknowns (the model parameters). As a solution to this problem, a spatial model’s reliability can be assessed by quantifying and representing model output uncertainty followed by sensitivity analysis (SA). Uncertainty analysis (UA) quantifies the model uncertainty and SA enables exploring the space of input factors to find out which contributes the most to the error and uncertainty in modeling. In this talk, I will demonstrate a generic recipe for UA-SA for spatial models, followed by representative examples for a land-use evaluation and a land-use forecasting model. And at the final step, the methods of visualizing the result of the integrated UA-SA framework will be examined by questioning their effectiveness on the end-users.

Seda Şalap-Ayça, has a BSc from Mining Engineering with a double minor in GIS and Remote Sensing. After her MSc in Geodetic and Geographic Technologies, she completed the Joint Doctoral Program in Geography at SDSU and UC Santa Barbara, where she specialized in spatial decision making, land-use models, uncertainty and sensitivity analysis for spatial models, and visualization of spatial model outputs. Currently, she is a lecturer at UMass, Amherst at Mt Ida Campus, where she teaches various levels of GIS courses in hybrid mode. Her current collaborative research project focuses on assessing social vulnerability and understanding the flood risk factors in Massachusetts.

Adapting to Environmental Change: Strategies for West Coast Shellfish Growers

Dr. Melissa Ward
Postdoctoral Researcher
Dept. of Geography and Coastal Marine Institute
San Diego State University

Friday, February 4, 2022
3:30 pm to 4:30 pm
Zoom Link: https://SDSU.zoom.us/j/89421546229
Meeting ID: 894 2154 6229
Passcode: 92182

The shellfish aquaculture industry along the West Coast is particularly vulnerable to ocean acidification (OA), given the negative effects of low pH on shellfish survival and growth. The social-ecological system exemplified by this industry serves as an opportunity to identify and address strategies for local adaptation. Through interviews conducted with West Coast shellfish growers, we find that growers are concerned about OA, among many other environmental stressors such as marine pathogens and water temperature. However, growers are often unable to attribute changes in shellfish survival or health to these environmental factors due to a lack of data and the resources and network required to acquire and interpret these data. From these interviews, we identify a list of adaptive strategies growers employ or would like to employ to improve their overall adaptive capacity to multiple stressors (environmental, economic, political), which together, allow farms to weather periods of OA-induced stress more effectively. In particular we explore the challenges, potential benefits, and science surrounding one adaptive strategy – co-locating shellfish aquaculture with eelgrass. We present recent work suggesting that eelgrass can elevate local pH, positively impacting co-located shellfish. However, implementing such a strategy comes with environmental and management challenges, which we explore here.

Melissa Ward received her PhD from the SDSU-UC Davis joint-doc program in Ecology and is currently a postdoctoral researcher at San Diego State University. Her research explores natural climate solutions, focusing on the biogeochemical processes associated with coastal carbon cycling and on understanding how human communities can adapt to climate change. Specifically, Melissa’s current work investigates the ways in which shellfish aquaculture growers can adapt to ocean acidification, and how seagrass might facilitate or challenge this adaptation.

AR4D and the Life Geographic

Dr. Steven Prager
Principal Scientist for Climate Resilient Food Systems
Climate Action

International Center for Tropical Agriculture
Alliance of Bioversity International and CIAT
Cali, Colombia

Friday, March 4, 2022
3:30 pm to 4:30 pm

Meeting ID: 817 8413 0249
Passcode: 92182

AR4D is shorthand for “Agricultural Research for Development”. All around the world there are dedicated individuals working to improve the livelihoods of smallholder agricultural producers and the environments on which those livelihoods (and lives) depend. AR4D covers an incredible gamut of topics from understanding the sustainability of food systems to improving crop varieties to developing highly tailored and locally adapted approaches for “climate smart agriculture”. In nearly every aspect of the AR4D process, geographers have the potential play an important role in helping smallholders adapt to the challenges presented by climate change, ever increasing globalization, and the changing food system.

In this talk, we will cover a range of AR4D-realted themes and discuss where geographers fit into this important area of research and practice. Whether one is interested in understanding and scaling equity in access to markets and agricultural technology or in improving seasonal agro-climactic forecasts for a specific region, understanding geography, geographic theory, and geographic information are critical. At the same time, “selling geography” is not always easy, and entry points for geographers into the AR4D world are not necessarily obvious. As such, in addition to considering a variety of different potential research areas, this talk will also address how to prepare oneself for an AR4D career or related scientific collaboration.

Steven Prager is a Principal Scientist for Climate Resilient Food Systems, based at the International Center for Tropical Agriculture (CIAT), in Cali, Colombia. There, Steve has led major contributions to the recently concluded CGIAR Global Futures and Strategic Foresight research activity, and a portfolio of projects related to the development of climate services and digital adaptation approaches for agriculture development. At CIAT, Steve works to facilitate more informed decision-making in a broad range of areas from investments in agricultural research to agriculture management practices, all with an eye toward supporting improved adaptation and mitigation strategies. Steve specializes in the use of decision-science and quantitative foresight approaches and leads a team of highly skilled geographers, data scientists, and modelers specializing in crop, climate and bioeconomic processes. Prior to joining CIAT, Steve was an Associate Professor of Geography at the University of Wyoming where he conducted research and taught in the area of Geographic Information Science.

Water Quality in Agricultural Landscapes: Ireland’s Agricultural Catchment Programme

Dr. Daniel Hawtree
Research Officer
Teagasc - Agricultural Catchment Programme

Adjunct Associate Professor
School of Biomolecular and Biomedical Science
University College Dublin, Ireland

Postponed: To be rescheduled.

The Agricultural Catchment Program (ACP) is a program initiated in Ireland in 2008 to monitor and assess the efficacy of measures put in place to protect water quality. To this end, a set of catchments were selected which represent a range of the most common agricultural and site conditions in Ireland, where long-term sampling stations could be established in cooperation with local farmers. At these sites, key variables are collected at high temporal resolution (e.g., 15-minutesampling time), which has provided a substantial trove of data on the hydrologic and nutrient dynamics in these catchments. Modelling efforts are now underway using these datasets to improve our capacity to predict future hydro-chemical fluxes under changing conditions, and to simulate alternate potential scenarios designed to meet Ireland’s obligations under EU regulations on agriculture and water quality. This seminar will provide an overview of the ACP and the current modelling work being undertaken, as well as touching on the other key components of the program (e.g., gaseous emissions, knowledge transfer, education).

Daniel Hawtree is a research officer at Teagasc (the Irish national body responsible for research, advisory, and training services to the agri-food industry) and an Adjunct Associate Professor at University College Dublin. At Teagasc, his research is focused on developing catchment models within the Agricultural Catchment Programme. Daniel is a native of San Diego and received both his BSc (Psychology) and MSc(Geography) at San Diego State University, which was then followed by a research internship at the European Commission Joint Research Centre (Ispra, Italy), and then a joint PhD split between Technische Universität Dresden and University of Padua. Since 2018, Daniel has been based in Ireland, where he carried out post-doctoral research at University College Dublin, before moving to Teagasc in 2021.

Remote Sensing of Wildfire Behavior: Needs, Challenges, and Advances

Dr. Mario Miguel Valero Pérez
Wildfire Interdisciplinary Research Center
San Jose State University

Friday, April 22
3:30 pm to 4:30 pm
Please complete the one-click registration in order to receive the Zoom invitation for the event.

While the undesired effects of wildfire continue to rise in many regions and fire modelers strive to develop new tools that support community adaptation, the fire science community continues to suffer from a severe shortage of fire behavior observations, especially at the landscape scale. Recent developments in remotely piloted aerial platforms and airborne optical sensors, as well as their growing adoption by fire researchers and fire management agencies, provide unprecedented opportunities to fill this data gap. However, systematic characterization of fire behavior entails important challenges caused by safety requirements, payload restrictions, and operational constraints. These limitations drastically reduce the resolution of achievable observations and increase the uncertainty of resulting measurements. In this talk, Dr. Valero will present his latest research in this field and discuss the needs, advances and remaining challenges.

Passcode: 92182

It has become a central topic in the social sciences to examine the conditions and outcomes of economic approaches for supporting conservation policies all around the world. Economics and economic activities are often conceptualized as contributing to alienation from nature, viewing nature as a commodity which delivers ecosystem services to be valued in order to provide benefits to people, without any considerations regarding the inherent value of nature itself. This commodification process is said to occur through various mechanisms such as monetary valuation, privatization, financialization, etc. Even if evidence supports the fact that these commodification processes are in progress, in-depth analysis reveals that these mechanisms are not necessarily well defined, that they are not new, neither are they irreversible, nor a one way trend. Indeed, the processes of commodification are more hybrid than assumed, and many trends can be considered as an “ecologization” of the economy and of economics. This presentation will provide a short history of the commodification and decommodification of nature.

Harold Levrel is a professor of ecological economics at AgroParisTech and the University of Paris-Saclay. He is a researcher at the Centre International de Recherche sur l'Environnement et le Développement (CIRED) and is co-director of the Ecological Accounting Chair. His work focuses on the conditions for implementing the ecological transition of the economy and biodiversity conservation policies. His fields of specialization are ecosystem services assessment, biodiversity offsetting, strong sustainability, social-ecological modelling, ecological accounting.

Socioeconomic Impacts of China’s Recent Forest Restoration and Conservation Programs

Dr. Conghe Song, Professor of Geography, University of North Carolina, Chapel Hill

Friday, September 4, 2020
3:30 pm to 4:30 pm

Since late 1990s China adopted a series of forest restoration and conservation programs after serious natural disasters resulting from long-term environmental degradation caused by unsustainable use of natural resources. In this talk, I will present the socioeconomic effects of the Conversion of Cropland to Forest Program (CCFP) and Ecological Welfare Forest Program (EWFP) on rural land use, out migration and household fuel choice and consumption in a remote mountainous township, Tiantangzhai, Anhui Province. CCFP is a forest restoration program that encourages farmers to convert croplands on slopes to forests for soil and water conservation based on the scheme of payment for ecosystem services. EWFP pays farmers to conserve forests that are of vital ecological value to the public. After controlling for other socioeconomic and environmental factors, we found CCFP strongly facilitated out migration and temporarily reduce cropland abandonment, while EWFP demotivated out migration and encouraged stable cropland usage. Neither program had a strong influence on rural household energy choice and fuel wood use. These findings highlight the need to coordinate concurrent conservation programs for achieving the targeted socioeconomic and ecological goals.

Conghe Song is currently a Professor of Geography and fellow in the Carolina Population Center at the University of North Carolina at Chapel Hill. He obtained his PhD degree from Boston University in Geography in 2001 and joined the Department of Geography at UNC Chapel Hill in the same year as an assistant professor, and subsequently rose through the ranks. He served as the Associate Chair and the Director for the Graduate Certificate Program in Geographic Information Sciences in the Department of Geography at UNC Chapel Hill during 2013-2019.

Dr. Song’s research focuses on three thematic questions: (1) how the land surfaces are changing through time? (2) what are the socioeconomic and ecological consequences of these changes? and (3) what are the forces that drive these changes? He uses remotely sensed data to measure land surface changes through time, such as biophysical parameters, land cover/land-use, and land surface phenology. He employs ecological models to integrate remote sensing and ground observation to understand how terrestrial ecosystem functions change as a result of land-cover/land-use change and climate change. He integrates household surveys, remote sensing and GIS, statistical models and agent-based models to understand the dynamics of coupled natural and human systems. He served as the PI for multiple grants funded by NSF, NASA and US Forest Service. His publications appeared on Remote Sensing of Environment, Global Change Biology, Nature, Ecology, Ecological Economics, Forest Policy and Economics, Population and Environment, and Land Use Policy et cetera. According to Google Scholar, his works had been cited for more than 7,000 times.

How Should We Scale From Trees to Landscapes? Predictions and Uncertainties for Forest Ecology in a Changing Climate

Dr. Anna Trugman, Assistant Professor of Geography, University of California, Santa Barbara

Friday, October 2, 2020
3:30 pm to 4:30 pm

Climate change has the potential to massively disrupt terrestrial ecosystem productivity, impacting biodiversity and ecosystem services, and driving Earth’s forests to release carbon into the atmosphere, which would further exacerbate climate change. Critically, the physiological mechanisms underpinning forest responses to climate are not fully understood due to complex interactions between climate, tree physiology, and community ecology. Here, I will talk about research leveraging an extensive trait database and a long-term continental forest plot network to map changes in community trait distributions and quantify ‘trait velocities’ (the rate of change in community-weighted traits) for different regions and different forest types across the U.S. from 2000 to the present. Next, I will highlight strengths and limitations in current traits-based approaches used to scale individual-based responses to processes, with a particular focus on drought driven tree mortality.

Anna Trugman received her bachelors degree from Stanford University in Geological and Environmental Sciences and her Ph.D. from Princeton University in Atmospheric and Oceanic Sciences. She has been an Assistant Professor in the Department of Geography at UC Santa Barbara since 2019.

 

Tobler‘s Law, Hurst’s Exponent, and Upper Ocean Turbulence

Dr. Nick Nidzieko, Assistant Professor of Geography, University of California, Santa Barbara

Friday, October 9, 2020
3:30 pm to 4:30 pm

A precise definition of “size”--encompassing both horizontal and vertical lengths scales--is essential to interpreting patterns in open ocean productivity. Whereas the physical boundaries of many ecosystem are quasi-stationary and often readily delineated by landforms, the boundaries of oceanic provinces are both subjective and fluid in time. In this talk I will consider how allometric relationships developed to quantify watershed characteristics can also be used to describe features generated by upper ocean mixing currents.

Nick Nidzieko is an Assistant Professor in the Department of Geography at UCSB. His work focuses on the contribution of physical processes in marine ecosystems and biogeochemical cycling.

 

Transit and Service Routing: Are We Really Finding Optimal Solutions, Does it Matter?

Dr. Richard Church, Distinguished Professor Emeritus of Geography, University of California, Santa Barbara

Friday, October 16, 2020
3:30 pm to 4:30 pm

The Arthur Getis Distinguished Lecture

This presentation discusses the three formulations, regarding transit and service routing, by Current et al. (1984; 1985) and Curtin and Biba (2011) and analyzes these three models when applied to a simple network. We demonstrate that these formulations may prevent optimal solutions or even feasible solutions from being found, even when they appear to be general and completely encompassing. Part of this can be explained as the result of a patently false premise under which these models were formulated and another part can be explained as the result of embedded errors in their formulations. New formulations will be developed which overcome these deficiencies and computational results will be presented.

Richard Church is Distinguished Professor Emeritus at the University of California, Santa Barbara. He received his PhD in Engineering from Johns Hopkins University. He is an expert in Operations Research and Management Science. Before coming to UCSB he was an associate Professor of Civil Engineering at the University of Tennessee. He has formally taught courses in Geography, Industrial Engineering, Management Science, and Civil Engineering.

Jump In, the Water‘s Fine: Participatory Approaches to Freshwater and Coastal Resource Management

Dr. Barbara Quimby, Research Scholar, Kyl Center for Water Policy, Arizona State University

Friday, October 23, 2020
3:30 pm to 4:30 pm

Engaging resource users and local communities in environmental planning and management is increasingly common, but the forms of this process vary and their outcomes are inconsistent. This talk presents research on stakeholder participation in local management decision-making and community-led research from two projects: a marine comanagement program in Samoa and a USDA-funded effort in Arizona addressing water and agriculture. In each context, participation in sustainable management planning is shaped by existing institutions, cultural values, and local perceptions of fairness.

Bridging the Gap: Integrating Critical Human and Physical Geography in Practice

Dr. Rebecca Lave, Professor of Geography, University of Indiana, Bloomington

Friday, November 13, 2020
3:30 pm to 4:30 pm

The relationship (or lack thereof) between physical and human geography is a longstanding discussion within our field. Some commentators assume the possibility of synthesis and call for integrated work; others assume that deep integration is neither possible nor desirable. But even a brief review of the literature makes two points glaringly clear: this discussion has been going on for a long, long time and, given its regular reoccurrence, it would seem we have little to show for it. Rather than debate the possibility or desirability of such integration, I argue here that there is already a strong and growing body of work that draws together critical human and physical geography in an emerging sub-field: critical physical geography. Individually or in teams, critical physical geographers are bridging the gap, combining insights from geomorphology, ecology, and biogeography with approaches from political ecology, science and technology studies, and environmental history. The key characteristics that unify this work are its emphasis on treating physical processes and unequal power relations with equal seriousness, its acknowledgment of the politics of knowledge production, and its normative agenda of using research to promote eco-social transformation. By way of illustration, I present the results of a critical physical geography study of market-based environmental management in the US that I conducted with Martin Doyle (Duke), and Morgan Robertson (U Wisconsin). Drawing on social science data from document analysis and interviews and natural science data from geomorphic fieldwork, I argue that while the fluvial landscape bears a clear signature of environmental policy, the development of ecosystem service markets in “stream credits” has different consequences than could be expected.

Rebecca Lave is Professor and Chair of the Department of Geography at Indiana University. Her research takes a critical physical geography approach, combining political economy, STS, and fluvial geomorphology. She has published in journals ranging from Science to Social Studies of Science, and is the author of Fields and Streams: Stream Restoration, Neoliberalism, and the Future of Environmental Science (2012), the lead editor of the Handbook of Critical Physical Geography (2018), and the co-author (with Martin Doyle) of Streams of Revenue: The Restoration Landscape and Ecosystems it Creates (2021). Her current research focuses on the eco-social history of the U.S. Midwest.

From Mario Kart to Pro-Poor Environmental Governance

Dr. Andrew Bell, Assistant Professor of Earth and Environment, Boston University

Friday, February 5, 2021
3:30 pm to 4:30 pm

Improving environmental stewardship requires improvement of the options available down to the poorest resource users. Agriculture will no longer be the path to development and better options that it once was, without rethinking how and where to intervene. I use an iconic video game as a lens into how some of this can happen, and discuss how I plan to apply it - that is, to “Mariokartize” environmental development - in current work to evaluate payments for ecosystems services (PES) in the Shire River Basin in Malawi.

My research focuses on the use of surveys, behavioral experiments, and agent-based models to understand decision-making in the areas of: agricultural development, water management, migration, and livelihoods.

 

Mountain Goat Conservation and Restoration in Washington

Dr. David Wallin, Professor of Environmental Sciences, Western Washington University

Friday, February 19, 2021
3:30 pm to 4:30 pm

Mountain goat populations in the Cascades Range of Washington State have declined from about 10,000 in the late 1950s-60s to about 3,000 today. Most of this decline is thought to be the result of overhunting from the 1960’s through the late 1980’s. I will discuss collaborative research and restoration efforts that have been underway over the past 15 years.

My research focuses on the regional-scale study of land-use effects on the structure and function of forest ecosystems. My work is heavily dependent on the use of simulation models, GIS, and satellite remote sensing. Although most of my work takes place in the Pacific Northwest, I’ve also been involved in comparative studies of land-use effects on forest structure in other parts of the world. Much of my recent work has focused on wildlife conservation and restoration and on the emerging field of landscape genetics.

Hybrid Urban Borderlands – An Urban Landscape- and Border-Theoretical Approach to the Redevelopment Processes In and Around Downtown San Diego

Albert Roßmeier, M.A.; PhD Candidate, Saarland University, Germany

Friday, April 9, 2021
3:30 pm to 4:30 pm

In recent years, downtown San Diego and its surrounding neighborhoods have experienced far-reaching urbanization and gentrification processes. In addition to the physical-structural developments which have reshaped the urban landscape, social upheavals have become apparent that still await in-depth analysis. In my talk, I will address individual interpretations and attributions in the context of San Diego’s downtown redevelopment from a phenomenological-oriented social constructivist urban landscape perspective. Within the aim of creating a wider understanding of the current upheavals, I am expanding my perspectival framework by exploring the potential of border-theoretical thinking for the research of individual experiences of neighborhood change, gentrification, and concomitant processes of social ‘b/ordering’ and ‘othering’. Surprisingly, border theories have only recently been applied on the level of urban neighborhoods, although these are particularly characterized by aspects of affiliation, differentiation, and participation. In response to this, I will illuminate the interdisciplinary benefits of this triangulation and illustrate how the ambiguous interpretations of San Diego’s changing central neighborhoods are creating fuzzy transition zones which I call hybrid urban borderlands.

Albert Roßmeier graduated in landscape architecture with a focus on urban planning at the University of Applied Sciences Weihenstephan-Triesdorf, followed by human geography at the University of Tuebingen. In Weihenstephan, he was employed from winter 2015 to winter 2016 as a research assistant in a project on landscape change and perception in the wake of the energy revolution, funded by the Federal Agency for Nature Conservation. From winter 2016 to spring 2019, he conducted research at the University of Tuebingen in the EU project ‘LIFE living Natura 2000,’ among others. He is currently working on his dissertation project on the transformation of inner-ring neighborhoods and urban ‘b/ordering’ processes in San Diego. His research interest includes energy system transformation, landscape change and theories, discourse theory, and urban/regional development in Europe and North America.

Resources for Health and Well-Being across Latinx Destinations

Dr. Liz Ackert, Assistant Professor of Geography, University of California, Santa Barbara

Friday, April 23, 2021
3:30 pm to 4:30 pm

The COVID19 pandemic has exposed place-based health vulnerabilities among Latinos/as. Geographic variation in health services and barriers to accessing these services have key implications for Latinx health access and outcomes in the COVID19 era and beyond. This research examines differences in general health services, immigrant-relevant health services, and barriers to accessing health services across Latinx communities. We investigate how health services and barriers to access differ across U.S. counties according to their histories as Latinx-receiving gateways.

I am an Assistant Professor in the Department of Geography at the University of California, Santa Barbara. My research interests include racial/ethnic inequality, immigration, education, health disparities, urban geography, and quantitative methods.

 

Ecosystem Services Assessment and Mapping with Pacific Northwest Stakeholders

Dr. Stephen Crook, Assistant Professor of Geography, Palomar College

Friday, April 30, 2021
3:30 pm to 4:30 pm

Over the last 25 years, the ecosystem services concept - the idea that humankind receives a variety of benefits from ecosystems - has been embraced globally by agencies tasked with conserving natural resources. However, there is a lack of clarity related to how the concept can be applied to decision-making processes and there are few examples of the concept being used to change management outcomes. My research has focused on engaging stakeholders in the identification and mapping of ecosystem services in a way that can more effectively and equitably inform the movement toward ecosystem service-based management in the US National Forest context. Such participatory methods can provide rich and meaningful answers to the fundamental questions of “which” ecosystem services should be considered and “where” those are most valued within a management unit. By engaging public lands stakeholders as a first step in ecosystem services-based management, agencies can fulfill statutory requirements to include ecosystem services in planning while better understanding human values related to public lands.

Stephen Crook is a 2020 graduate of the Joint Doctoral Program in Geography at SDSU and UC Santa Barbara, where he specialized in human-environment interaction, environmental policy, and conservation GIS. Broadly, his research has focused on using (and often integrating) social surveys, participatory mapping, and remote sensing data to understand perceptions of, use of, and impact on natural areas. He is an Assistant Professor of Geography and GIS at Palomar College where he spends his time writing GIS labs and planning geography field courses for a post-pandemic world!

Colloquia Series

Resilience to Earthquakes and Droughts: Some Insights from the Israeli Experience

Dr. Eran Feitelson
Head, Advanced School for Environmental Studies
The Hebrew University of Jerusalem, Israel

Friday, September 20, 2019
3:30 pm to 4:30 pm
Storm Hall 316

California and Israel are prone to both droughts and earthquakes. Yet the two types of disasters have very different attributes. While earthquakes are sudden, deadly and threaten mainly urban centers, droughts are slowly evolving, often multi-year, affect mainly farming and natural ecosystems with very little effects on the urban fabric. In this talk, I discuss the extent to which Israel is resilient to these two diametrically opposed types of disasters.

Through the implementation of a wide set of policy tools, most recently large-scale seawater desalination, Israel has largely decoupled itself from the effects of droughts (with the exception of the Jordan River basin). Israel has also invested much effort in immediate responses to earthquakes. However, little has been done in Israel with regard to the retrofitting of older buildings – the buildings most likely to be affected by earthquakes. Thus, the most effective measure to reduce casualties has lagged behind, as well as the preparation for the day after. Thus, the overall picture is that the highest risks are not addressed, while lesser risks are better addressed.

I explain these results from two perspectives – the first is the frequency of events and the second is the institutional structures in place. These explanations are hypothesized to be pertinent also in other settings.

Eran Feitelson is a professor at the Department of Geography of the Hebrew University of Jerusalem. He is the founder and first head of the Advanced School for Environmental Studies, a previous head of the Federmann School of Public Policy and Government and previous chair of the Department of Geography. He has published extensively in the fields of water policy, trans-boundary water, transport policy, land use planning, environmental policies and more recently earthquake preparedness. In addition to his academic work Eran Feitelson has participated in several national planning teams and has been a member of various national committees. He also serves for the second time as chair of the Israeli National Parks and Nature Reserves Commission.

 

Tracking Infectious Diseases Using Big Data: A Primer Using Search Data and Social Media

Dr. Eyal Oren
Associate Professor, Epidemiology & Biostatistics
Graduate School of Public Health
San Diego State University

Friday, September 27, 2019
3:30 pm to 4:30 pm
Storm Hall 316

This presentation focuses on the utility of big data sources to provide unique real time information on common and not-so-common infectious diseases. We will examine how the age of ‘digital epidemiology’ allows us to track disease spread and provides information pertinent to assessing clinical parameters such as the severity of infections using search and social media. We will also assess how both information and ‘misinformation’ feeds into public perceptions and resulting actions in the face of an infectious disease outbreak.

Eyal Oren is Associate Professor of Epidemiology at San Diego State University, with training as an infectious disease, spatial and social epidemiologist. He has extensive experience in epidemiological and clinical research, working on the effective adoption of interventions in the community as well as in developing evidence-based strategies and practices from secondary data analyses and novel data sources. He is particularly interested in using crowd-sourced and participatory data to enhance population health research. He holds a PhD and MS in epidemiology from the University of Washington.

California Environmental Flows Framework: Striking the Balance Between Ecological and Human Water Uses

Dr. Kristine Taniguchi-Quan
Hydrologist
Southern California Coastal Water Research Project

Friday, November 1, 2019
3:30 pm to 4:30 pm
Storm Hall 316

Establishing environmental flow targets is a priority for numerous programs in California. Although methods vary based on the ecological endpoint of management concern (e.g. fish, macroinvertebrates, habitat), stream type, and preferences of the implementing agency, each effort aims to determine flow conditions necessary to protect ecological integrity in light of competing water uses. Unfortunately, lack of coordination among programs and efforts leads to inefficiencies, difficulty in comparing approaches, inability to share outputs, and creates potential for competing recommendations.

A statewide technical workgroup has convened to develop a framework for organizing environmental flow analyses across California and provide consistent science-based recommendations for applying appropriate methods to inform setting and managing of environmental flows. The California Environmental Flows Framework (CEFF) is a step-wise approach that promotes consistency and coordination in establishing, maintaining, and monitoring in-stream flow requirements for California. The overall goal of this effort is to support various regulatory and management agencies in developing and implementing local, regional, and statewide in-stream flow targets to protect aquatic life beneficial uses. Southern California case studies will be highlighted to illustrate urban water use challenges, and optimizing flows for ecological and human uses.

Kris Taniguchi-Quan is a scientist at Southern California Coastal Water Research Project (SCCWRP).

A Spatial Data Science Framework for Movement

Dr. Somayeh Dodge
Assistant Professor of Geography
University of California, Santa Barbara

Friday, November 15, 2019
3:30 pm to 4:30 pm
Storm Hall 316

Movement is the driving force behind the form and function of many ecological and human systems. Identification and analysis of patterns of movement that may relate to the behavior or interactions of individuals is a fundamental first step in understanding these systems. Ubiquitous collection of geo-enriched tracking data necessitates new approaches for the analysis and sense-making of large and multidimensional arrays of information about movement of individuals, goods, vehicles and other mobile agents in space and time. To take advantage of the evolution in our data, effective representations and analytical approaches are necessary to reveal and communicate important patterns in spatiotemporal data sets and inform us about the processes involved in social and ecological systems. This study presents a data science framework and attendant methods for analysis, modeling, and mapping movement as a multidimensional process that involves space, time, context, and scale.

Somayeh serves as Assistant Professor of Spatial Data Science in the Department of Geography at the University of California, Santa Barbara. She received her PhD in Geography with a specialization in Geographic Information Science (GIScience) from the University of Zurich, Switzerland in October 2011. She holds a MS degree in GIS Engineering and a BS degree in Geomatics Engineering from the KNT University of Technology, Iran. Somayeh’s research focuses on developing data analytics, knowledge discovery, modeling, and visualization techniques to study movement. Her research applies spatial data science and computational approaches to advance the knowledge and understanding of how movement patterns are formed in dynamic natural and human systems. She has published in a number of high-ranked international journals such as Methods in Ecology and Evolution, International Journal of Geographic Information Science, Philosophical Transactions of the Royal Society B, Journal of Spatial Information Science, Movement Ecology, Computers, Environment and Urban Systems (CEUS), Geographical Analysis, and Information Visualization. Somayeh currently serves as the Editor in Chief of the Journal of Spatial Information Science. She is involved in the editorial boards of multiple journals including Geographical Analysis, CEUS, and The Professional Geographer.

Transgressions of Spatial Rigidity: How Black and Indigenous Women (Re)Story Movements

Dr. Esme G. Murdock
Assistant Professor of Philosophy
Associate Director, Institute for Ethics and Public Affairs
San Diego State University

Friday, February 21, 2020
3:30 pm to 4:30 pm
Storm Hall 316

Settler colonialism as a violent land-orientated, social-spatial system/structure is deeply committed to projects of spatial dominance that include conceptions of “nation” and “home” as fixed, bounded, and unchanging sites. In addition to this allegiance to spatial rigidity, settler colonialism also has dominant and oppressive attitudes toward both movement and migration, especially that of non-dominant, non-white Others. Critical geographers, especially those invested in complicating hegemonic constructions of space and place through exploring investigations of Black and Indigenous geographies, give us insight into how dominant spatial constructions cannot only be disrupted, but also (re)storied for the purposes of resistance. In this presentation, I will focus on the (re)storying of both migration and movement as a site of resistance, futurity, and self-determination as presented in the centering of Black and Indigenous women’s lived knowledges in North America. Specifically, I will examine how the migration and movement, as well as the obstacles to such migration and movement, of Black and Indigenous women reveals ruptures ripe for theorizing the indeterminacy and incompleteness of settler colonial projects of spatial closure.

Esme G. Murdock is Assistant Professor of Philosophy and Associate Director of the Institute for Ethics and Public Affairs at San Diego State University. She works in the areas of environmental philosophy and environmental ethics and social and political philosophy with particular attention to environmental justice, philosophies of race and gender, and settler colonial theory. Her research explores the intersections of social/political relations and environmental health, integrity, and agency. Specifically, her work troubles the purported stability of dominant, largely euro-descendent, and settler-colonial philosophies through centering conceptions of land and relating to land found within African American, Afro-Diasporic, and Indigenous eco-philosophies.

 

Documentary Film Screening: CITY RISING: The Informal Economy

Dr. Pascale Joassart-Marcelli
Professor of Geography
Documentary Co-Producer
San Diego State University

CITY RISING: The Informal Economy examines a growing segment of our economy, which consists of unregulated and unprotected jobs. It exposes this trend as the result of policy choices and practices that have historically kept many jobs out of reach for women, immigrants and people of color who have turned to the informal economy to make a living and support their communities. The film follows workers in California who labor off the books—often in plainsight—and are organizing to find pathways to legalization and protection.

Screening followed by Q&A with film co-producer Pascale Joassart-Marcelli.

The CITY RISING Series, produced by KCET in collaboration with the California Endowment, is a multi-platform initiative that highlights how individuals facing social and environmental injustice fight to change policy and lift up their communities.

Student Union, Templo Mayor

Dr. Sergio Rey
Professor of Public Policy
Director, Center for Geospatial Sciences
University of California, Riverside

San Diego State University
Distinguished Speaker Series
Sponsored by Department of Geography, College of Arts and Letters, Graduate and Research Affairs

In this talk, I examine the field of Geographical Information Science (GIScience) from the perspective of broader developments surrounding open source software and the rising open science movement. Despite its reliance on code in general, and open source software in particular, GIScience has only recently begun to seriously engage with what are seismic shifts in the underpinnings of science driven by the open revolution. I suggest a number of possible explanations for this delayed engagement. Next, I discuss the obstacles to, and opportunities for, reinventing GIScience as an open science and transforming GIScience education. I highlight a selection of exemplar efforts leading the charge and offer some thoughts on likely future developments and possible ways forward for the discipline.

Sergio Rey is Professor in the School of Public Policy and Founding Director of the Center for Geospatial Sciences at UCR. Dr. Rey’s research interests focus on the development, implementation, and application of advanced methods of spatial and space-time data analysis.

Geospatial Data for Forecasting Global Change Impacts on Ecosystems

Tuesday, February 4, 2020
4:00 pm to 5:00 pm
Student Union, Templo Mayor

Dr. Janet Franklin
Distinguished Professor of Botany and Plant Science
University of California, Riverside

San Diego State University
Distinguished Speaker Series
Sponsored by Department of Geography, College of Arts and Letters, Graduate and Research Affairs

Human activities have altered global patterns of biodiversity, and key processes of energy balance and biogeochemical cycling in the Earth system, especially over the last 500 years. These changes have been so profound that they are detectable in the geological record and some have suggested that this is a new geological era, The Anthropocene. Owing to the anthropogenic global change agents—land use change, climate change, nitrogen deposition, altered disturbance regimes and transport of invasive species—the planet may have already moved outside of a safe operating space for humanity in several dimensions. I use geospatial data in my research for monitoring and forecasting the effects of land-use change (deforestation and urbanization leading to habitat loss and fragmentation), and climate change on biodiversity and ecosystem function. Processes leading to biodiversity loss are inherently spatial. Knowing where biodiversity is found is the basis for spatial conservation planning. Knowing where on the landscape threats occur in relation to biodiversity is prerequisite to monitoring impacts. Forecasting where threats might occur in the future allows prediction of future impacts. The effects of climate change on species and ecosystems is already detectable globally, with earlier arrival of spring affecting plant and animal phenology, bird and other animal migrations, and so forth, and with species distributions shifting in directions consistent with observed climate changes. I will show how static species distribution models, and dynamic population and community simulations, have been used to forecast the separate and combine impacts of climate and land use change on biodiversity and ecosystems.

Janet Franklin is a Distinguished Professor in the Department of Botany, University of California at Riverside where she has been since 2017. She was previously a Regent’s Professor in the School of Geographical Sciences and Urban Planning, as well as a Distinguished Sustainability Scientist at Arizona State University where she was appointed in 2009. From 1988-2009 she was and Assistant, Associate, and Full Professor on the faculties of Geography and Biology at San Diego State University. She received her Ph.D. in Geography from the University of California, Santa Barbara in 1988. She specializes in Landscape Ecology, Global Change Biology, Conservation Biogeography, and Geographic Information Science. Franklin’s research is focused on in the patterns and dynamics of terrestrial (land) plant communities at the landscape scale. Her work addresses the impacts of human-caused landscape change on the environment. Human land use—agriculture and urbanization—and other large-scale human impacts such as climate change, and the introduction of exotic species, often interact with natural disturbance regimes such as fire, flooding and hurricanes, to shape plant community dynamics in forests, shrublands, and other ecosystems. How resilient are ecological communities to these past, present and future impacts?
