Yi-Fu Tuan Lectures
The Yi-Fu Lecture Series features a wide variety of U.S. and international guest lecturers from all geographic disciplines. Lecturers at these Friday seminars also often speak at brown-bag lunches, one-on-one student sessions, and breakfast meetings with student interest groups as part of their visit. Doctoral students are invited to present their final research. The lecture series was initiated by Dr. Tuan (pictured at right) and receives enthusiastic support as a department and campus tradition.
All lectures are presented on Friday at 3:30pm in Science Hall - Rm 180 unless otherwise noted.
Alumni, friends and the public are always invited to attend.
Spring 2014 Lectures
24 January – Exploring Multiresolution Approaches to Regional Climate Simulation
- Sara Rauscher,University of Delaware, Geography Department
The lack of reliable regional climate projections represents one of the largest gaps in climate change science. Traditionally, three dynamical modeling methods have been used to obtain regional climate information: limited area (or regional) climate models (RCMs) driven by reanalysis or global model boundary conditions, usually in one-way nesting mode; high resolution global climate models (GCMs); and variable resolution techniques. Regional climate models offer high resolution at reduced cost compared to high resolution global modeling, but issues such as ill-posed boundary conditions, mismatches between the driving GCM and the RCM dynamics and physics, and the lack of "upscale" effects continue to call into question the validity of RCMs. Global high resolution simulations require millions of computing hours and produce large data sets that are difficult to manage. Variable resolution (or multiresolution) approaches offer a compromise, with reduced computational cost compared to global high resolution simulations and internal consistency and interactions between the large scale and regional scales that are absent in RCMs. Here we explore the multiresolution approach to regional climate simulation by evaluating a suite of idealized and real-world simulations performed with the new Model for Prediction Across Scales (MPAS-A) dynamical core implemented within the NSF-DOE Community Earth System Model. MPAS-A is an unstructured-grid approach to climate system modeling that supports both quasi-uniform and variable resolution meshing of the sphere. Using an idealized aquaplanet setup, we first ask if the high-resolution region of a variable resolution simulation "looks" and "acts" like a quasi-uniform simulation that uses this high resolution everywhere.* (We assume that the global high resolution simulation is the truth.) Further, are there any upscaled impacts from the high resolution region to the outer coarse resolution region?** Finally, how does the model respond to varying grid resolution?*** Answering these questions leads us to an unexpected conclusion: the best application of the multi-resolution approach may be to elegantly quantify model improvements.
*Yes. **Yes. ***Crankily.
31 January – Human Geography Without Hierarchy
- Simon Springer, University of Victoria, Geography Department
Responding to neoliberal decentralization, Marxists pair centralization with capitalism’s abrogation. Such a view considers hierarchy to be necessary and horizontal organization as propitious to neoliberalism. Anarchism’s coupling of decentralization with anti-capitalism is dismissed because Marxism cannot accommodate prefigurative politics, treating horizontality as a future objective. This temporality ignores the insurrectionary possibilities of the present and implies a politics of waiting. In terms of spatiality, Marxian centralized hierarchy deems horizontality inappropriate when ‘jumping scales’. Yet by rejecting this vertical ontology we may immediately disengage capitalism through a rhizomic politics. Consequently, human geography without hierarchy gains traction when we embrace an anarchist flat ontology.
7 February – Effectiveness and synergies of policy instruments for land use governance in tropical regions
- Eric Lambin, Stanford University, School of Earth Sciences
- Co-sponsored by SAGE
Traditionally, land use is regulated through command-and-control interventions such as land use zoning and protected areas. More recently, private actors have designed market-based policy instruments to influence land use – e.g., eco-certification, geographical indications, commodity roundtables and moratoriums. Other interventions, such as payments for environmental services, fall along a continuum of instruments that vary in the degree of state involvement. These alternative regulatory mechanisms are interacting with traditional public forms of land use regulation, leading to “hybrid” interventions. In this talk, I will discuss the effectiveness of the main instruments used to promote sustainable land use, and explore interactions between these instruments. Overall, there is a lack of rigorous studies on the effectiveness of new regulatory mechanisms of land use, but available evidence suggests some potentially positive direct and indirect beneficial impacts. Private regulation systems serve optimally within policy mixes with a complement of baseline public law. I propose a typology of potential interactions between public, private and hybrid instruments used in land use governance.
14 February – Capitalism against Markets: Why Everything will not be Commodified
- Derek Hall, Wilfrid Laurier University
- Co-Sponsored with CSEAS
The argument that we are witnessing "the commodification of everything" is a common theme in contemporary analyses of capitalism and neoliberalism. In this talk, Derek Hall makes the case that this argument misunderstands the vital role in capitalist social relations played by certain kinds of decommodification, and uses a wide range of historical examples to show that a world in which everything really was commodified would not look anything like capitalism.
19 February – Remaking the Edges: Sub-Saharan Africa’s New Suburbs
- Garth Myers, Trinity College, Urban International Studies
- Co-sponsored with the Department of African Studies
This paper chapter examines the edge areas of Lusaka, based on fieldwork from 2013, as a broad example of the trajectory of urban expansion at the new urban frontiers in Sub-Saharan Africa. I emphasize four themes: (1) the significance of new foreign investment in urban frontier zones (particularly from China); (2) the bifurcated character of the expansion; (3) the rise of surveillance technologies; and (4) the endurance of continuities with European colonialism. NOTE WEDNESDAY DATE: This talk will take place from 12- 1pm, 206 Ingraham Hall
21 February – Spatial Big Data: A Perspective
- Shashi Shekhar, University of Minnesota, Dept of Computer Science
Increasingly, the size, variety, update rate and complexity of location-based datasets exceed the capacity of common spatial computing platforms to manage, process, and analyze the data with reasonable effort. Such data is known as Spatial Big Data (SBD). Examples include cell-phone trajectories, location-based service requests, social media check-ins, sensor-measurements, temporally-detailed roadmaps, etc. SBD has transformative potential. For example, a 2011 McKinsey Global Institute report estimates savings of about $600 billion annually by 2020 in terms of fuel and time saved by helping vehicles avoid congestion and idling. Geo-social media is leveraged for timely detection of tornadoes and outbreaks. Sciences are investigating SBDs for questions, where progress was hampered by data paucity. SBD challenges, opportunities and debates arise at the level of platforms, analytics and scientific methods. Platforms (e.g., Hadoop, SQL/OGIS) are challenged iterative and interdependent spatial algorithms as well as increasing variety (e.g., Lagrangian frame of reference). Opportunities include both adaptation to current platforms (e.g., non-iterative algorithms) and explorations of alternative platforms. Analytics methods are challenged by geographic heterogeneity and reducing user burden by estimating neighborhood relationships. A current debate juxtaposes rise of both simpler models (e.g., data as the model) and more complex models (e.g., ensembles). Scientific method debates include data quality measures (e.g., bias vs. timeliness), impact of corporate ownership of SBD on transparency and reproducibility, and effect of data-intensive science (fourth paradigm) of classical methods (e.g., theory-based, hypothesis testing).
28 February – Water, Privatization, and Community in Cochabamba, Bolivia
- Erica Simmons
- UW-Madison, Political Science Department
In January 2000, thousands of Bolivians took to the streets to protest the privatization of the Cochabamban water supply. The events pose a puzzle for social science scholars; traditional social movement approaches fall short of offering a satisfactory explanation. To explain the origins and internal dynamics of the Cochabamban water movement, this paper argues that we must include an analysis of the moral and material claims that citizens make—namely, the grievance. Specifically, scholars must pay systematic attention to the meaning of the grievance. Two specific questions motivate the paper. What accounts for the strong opposition to the privatization of water in Cochabamba when earlier Bolivian privatizations and reforms had passed with little unrest? How do we explain the cross-class, cross-ethnic, cross-urban-rural, and highly diverse nature of the movement? It is impossible to answer these questions without paying close attention to the meanings that water took on in the Cochabamban context. The paper uses the Cochabamban case to develop a broader theory connecting market-driven threats to subsistence resources and patterns of political protest. Evidence from the water wars suggests that market-driven threats to subsistence resources are a particularly powerful locus for collective action because these resources are imbued with meanings beyond their apparent “material” value. Often evoking imagined communities of nation, region or ethnic group, or the face-to-face interactions that revolve around a subsistence good’s routine production and consumption, subsistence grievances serve as particularly powerful loci for resistance around which salient local divisions can coalesce, resulting in broad-based, diverse opposition movements. Through close attention to local understandings of, practices related to, and relationships surrounding water, as well as the resource’s national patrimonial associations, the paper shows how it was not just the material qualities of water, but how those material qualities took on meaning in the Cochabamban context that contributed to causing widespread resistance.
7 March – Maps as Rhetorical Weapons (or: Persuading People to See It Your Way)
- Ian Muehlenhaus
- University of Wisconsin - La Crosse, Geography & Earth Science
Maps are not accurate representations of reality; they are merely a form of spatial communication. All maps posit arguments about our world. Like all forms of communication, they use different rhetorical styles and techniques to frame these arguments. In this talk, I focus on what are commonly called persuasive maps (i.e., maps that present sociopathic arguments). I review an initial taxonomy of persuasive map rhetorical styles. This is followed by a review of two user studies testing the impact these rhetorical styles have in persuading people to see a controversial social issue from a particular perspective. Using these results, I critique visualization theory’s obsession with data richness and accuracy. I propose that we rethink how we evaluate effective map design and stop chastising overtly biased maps.
28 March – Drones and the Everywhere War

- University of British Columbia, Geography Department
4 April – Space, Place, Nature: One Last Look
- Yi-Fu Tuan, Professor Emeritus, UW-Madison Geography Department
I have been writing about "Space, Place, and Nature" for at least three decades. You'd think I am now able to say something about them that is authoritative, if not definitive. But--thank God!--not at all. "Space" and "place," yes, I can sound professorial, but "nature" and "what is reality" completely elude me, making me feel like a beginner. And it is as a beginner that I wish to make this farewell speech to colleagues in Science Hall, but especially to students who, I hope, will--even in their eighties--remain as immature as I am.
There will be a reception in the Map Library following the lecture.
8 April – TBA

18 April – Ethiopia's Grand Renaissance Dam: What does it mean for riparian countries along the Nile
- Paul Block, UW-Madison, Dept of Civil & Environmental Engineering
Ethiopia's Grand Renaissance Dam on the Blue Nile River, currently under construction, will be the largest dam in Africa. Yet critical questions regarding the reservoir filling strategy, hydropower generation, and subsequent long and short-term effects on streamflow for downstream countries have not been addressed. This presentation will explore plausible outcomes of this massive infrastructure project.
25 April – From the U.S. South to the Global South: Practicing Development at Home
- Mona Domosh
- Dartmouth, Geography Department
Drawing on a range of works that extend from gendered historical analyses of colonialism to critical histories of development, and based on archival research in Alabama, Arkansas, and Mississippi, I argue in this talk that what we now call international development – a form of hegemony different from but related to colonialism – needs to be understood not only as a geopolitical tool of the cold war, but also as a technique of governance that took shape within the realm of the domestic and through a racialized gaze. I do so by tracing some of the key elements of the United States’ international development practices in the postwar era to a different time and place: the American South, a region considered ‘undeveloped’ in the first decades of the 20th century, and the agricultural extension practices that targeted the rural farm home and farm women, particularly African-American women. Thus I am able to interrogate two relatively unexamined elements that are key to understanding the making of American international development: that much of its early focus was on governing through biopolitical practices of the domestic (food preparation, health, and sanitation), and that those practices were based on the agricultural extension work of the United States Department of Agriculture in the American South.
