Writing with your eyes closed

Geography alumnus Joel Burcat ’76 has published a novel

Joel Burcat’s debut novel, “Drink to Every Beast,” isn’t climbing best-seller lists or getting attention from prominent critics. But it’s remarkable for a different reason.

He finished it after he became legally blind.

An environmental lawyer in Harrisburg, Pa., Burcat, 64, had been writing in his spare time for many years and had cranked out several novels, including an early version of this one. But none had found a publisher and gone out into the world.

From Scientific American
Historic Greenland Melt Is a “Glimpse of the Future”

Luke Trusel is quoted

Greenland is in the midst of one of its strongest melting events on record, as a major heat wave—the same one that scorched much of Europe last month—grips the Arctic.

Ice sheet experts have been keeping careful watch as the event unfolds, taking note of its extraordinary progress. Throughout July, Greenland lost an estimated total of 197 billion metric tons of ice, researcher Ruth Mottram of the Danish Meteorological Institute tweeted early Wednesday morning. That day, the largest melt day of the month, the institute estimated that more than half the ice sheet was experiencing some level of surface melting, and about 10 billion tons of ice was lost in a single day.

Dynamically Optimized Unstructured Grid (DOUG) for Analog Ensemble of numerical weather predictions using evolutionary algorithms

Weiming Hu, Guido Cervone
Computers & Geosciences
https://doi.org/10.1016/j.cageo.2019.07.003
The Analog Ensemble is a statistical technique that generates probabilistic forecasts using a current deterministic prediction, a set of historical predictions, and the associated observations. It generates ensemble forecasts by first identifying the most similar past predictions to the current one, and then summarizing the corresponding observations. This is a computationally efficient solution for ensemble modeling because it does not require multiple numerical weather prediction simulations, but a single model realization. Despite this intrinsic computational efficiency, the required computation can grow very large because atmospheric models are routinely run with increasing resolutions. For example, the North American Mesoscale forecast system contains over 262 792 grid points to generate a 12 km prediction. The North American Mesoscale model generally uses a structured grid to represent the domain, despite the fact that certain physical changes occur non-uniformly across space and time. For example, temperature changes tend to occur more rapidly in mountains than plains. An evolutionary algorithm is proposed to dynamically and automatically learn the optimal unstructured grid pattern. This iterative evolutionary algorithm is guided by Darwinian evolutionary rule generation and instantiation to identify grid vertices. Analog computations are performed only at vertices. Therefore, minimizing the number of vertices and identifying their locations are paramount to optimizing the available computational resources, minimizing queue time, and ultimately achieving better results. The optimal unstructured grid is then reused to guide the predictions for a variety of applications like temperature and wind speed.

Relationships of West Greenland supraglacial melt‐lakes with local climate and regional atmospheric circulation

Rowley, N. A., Carleton, A. M. and Fegyveresi, J.
International Journal of Climatology
doi:10.1002/joc.6262
Along the west‐central Greenland ice‐sheet (GrIS) ablation zone, the time of annual maximum occurrence of surface melt lakes, or peak lake period (PLP) averages 18 June–03 July. This study combines atmospheric reanalysis and automatic weather station (AWS) data from the Greenland Climate Network to assess the roles of synoptic circulation patterns and local climate variables, respectively, in the total melt‐lake area and count in the Sermeq Kujalleq Ablation Region (SKAR) for the PLPs of 2000–2016. Melt‐lake information is obtained from analysis of Landsat‐7 images. Two surface climate parameters (e.g., temperature, incoming shortwave radiation) having a strong combined effect on melt‐lake area in the SKAR are the June mean temperature, and May mean incoming solar radiation (r = 0.96). Incorporating the May insolation into a regression equation permits predictability of total melt‐lake area for the study area into late June. June months classified as high melt correlate regionally with mid‐tropospheric ridging, warm air advection, and reduced cloud cover, while low melt June months are associated with a trough, cold advection and greater cloud amount. A localized feature that we found to be prevalent during the high melt years are piteraq, or downsloping winds, which provide additional warming to the SKAR from adiabatic compression. Atmospheric circulation indices comprising the North Atlantic Oscillation (NAOI) teleconnection and Greenland Blocking (GBI) pattern augment the reanalysis gridded data. We find statistically significant correlations of the NAOI and GBI with melt‐lake area (r = −0.62 and r = 0.77, respectively). The correlations with melt‐lake count however, are not significant; greater combined lake area and count tend to accompany the meridional mode of high amplitude Rossby waves and/or anticyclonic blocking in the Greenland sector. Determining the local and synoptic‐scale atmospheric controls on supraglacial lake variability helps clarify the role of climate in the surface hydrology of the GrIS.

Spatial and temporal dynamics of 20th century carbon storage and emissions after wildfire in an old-growth forest landscape

Both fire exclusion and subsequent wildfires have strongly affected carbon storage in fire-prone dry forests, with implications for how carbon storage will change in the future. Using a reconstruction of forest structure in 1899 and pre- and post-fire field data, we quantified changes in carbon stocks in a 2125-ha old-growth mixed conifer forest landscape over a century of fire exclusion and emissions due to a 2013 wildfire. From 1899 to 2002 aboveground carbon storage in live trees increased 2.5-fold from 97 Mg/ha to 263 Mg/ha. Despite burning in an uncharacteristically severe wildfire, the forest still contained 169 Mg/ha of live aboveground tree carbon in 2014. Direct fire emissions were 72 Mg/ha and did not vary with canopy cover loss because emissions were largely driven by consumption of accumulated surface fuels. Areas that burned at low, moderate and high severity in the wildfire contained similar amounts of carbon in 1899, when the forest was still experiencing frequent low severity fire. By 2002 the low severity areas contained 80 and 86 Mg/ha more aboveground live tree carbon than moderate and high severity areas respectively. The wildfire reinforced and amplified these differences in carbon storage that arose during fire exclusion, such that carbon storage following the wildfire was more variable across the landscape. Additionally, the proportion of carbon stored in shade-intolerant, more fire-sensitive species increased. These changes in where and in what tree species carbon is stored, due to the combination of fire exclusion and wildfire, have implications for the potential future stability of these carbon stocks.

Human migration to and from rural areas is so prominent and persistent globally that land system science must understand how the movement of people is integral to land system transitions both at the origin of migration and at its destination. With a focus on Latin America, we review research on how land change affects migration and how migration affects land systems, to demonstrate that the relationship is complex and context-specific. Various types of migration evidence the challenges of managing land for multiple goals and the needs of diverse groups. A perspective that connects land change in multiple locations is needed. In particular, concepts of telecoupling and translocality can help to further understanding of how globalized economic systems link changes across distant places and capture the economic and non-economic processes that accompany migration and shape land change in multiple, connected locations. Land systems research must anticipate that migration will continue to contribute to complex land systems with multiple users and goals.

Modeling the Importance of Within- and Between-County Effects in an Ecological Study of the Association Between Social Capital and Mental Distress

Yang, T. C., Matthews, S. A., Sun, F., & Armendariz, M.
Preventing chronic disease
doi:10.5888/pcd16.180491
Introduction: Levels of mental distress in the United States are a health policy concern. The association between social capital and mental distress is well documented, but evidence comes primarily from individual-level studies. Our objective was to examine this association at the county level with advanced spatial econometric methods and to explore the importance of between-county effects.
Methods: We used County Health Rankings and Roadmaps data for 3,106 counties of the contiguous United States. We used spatial Durbin modeling to assess the direct (within a county) and indirect (between neighboring counties) effects of social capital on mental distress. We also examined the spatial spillover effects from neighboring counties based on higher-order spatial weights matrices.
Results: Counties with the highest prevalence of mental distress were found in regional clusters where levels of social capital were low, including the Black Belt, central/southern Appalachia, on the Mississippi River, and around some Indian Reservations. Most of the association between social capital and mental distress was indirect, from the neighboring counties, although significant direct effects showed the within-county association. Models also confirmed the importance of county-level socioeconomic status.
Conclusion: We found that county social capital is negatively related to mental distress. Counties are not isolated places and are often part of wider labor and housing markets, so understanding spatial dependencies is important in addressing population-level mental distress.

Transforming Earth Science Education Through Immersive Experiences: Delivering on a Long Held Promise

The value of field trips is undisputed across disciplines. Field-site visits whether in social or physical sciences provide grounding for place- and discovery-based learning. Yet field trips have limitations that can now be overcome by the promise of immersive technologies that can improve quality and accessibility. This promise is twofold: First, we can harness advancements made in sensing technologies to create immersive experiences of places across the earth efficiently; second, we can provide detailed empirical evaluations on immersive learning and quantify educational value. We report on a study that splits an introductory geosciences course into two groups with one group experiencing a traditional field trip, while a second group visits the same site virtually, immersing the students in the site using a head-mounted device. Results show the advantages of virtual field trips (VFTs) concerning enjoyment, learning experience, and actual lab scores. We embed the discussion of these results into a more general assessment of the advantages of VFTs and a taxonomy of VFTs as a basis for future studies.

Scale – Unexplored Opportunities for Immersive Technologies in Place-based Learning

Conference Paper, IEEE VR 2019 Osaka, Japan
https://www.researchgate.net/publication/334000521_Scale_-_Unexplored_Opportunities_for_Immersive_Technologies_in_Place-based_Learning
Immersive technologies have the potential to overcome physical limitations and virtually deliver field site experiences, for example, into the classroom. Yet, little is known about the features of immersive technologies that contribute to successful place-based learning. Immersive technologies afford embodied experiences by mimicking natural embodied interactions through a user’s egocentric perspective. Additionally, they allow for beyond reality experiences integrating contextual information that cannot be provided at actual field sites. The current study singles out one aspect of place-based learning: Scale. In an empirical evaluation, scale was manipulated as part of two immersive virtual field trip (iVFT) experiences in order to disentangle its effect on place-based learning. Students either attended an actual field trip (AFT) or experienced one of two iVFTs using a head-mounted display. The iVFTs either mimicked the actual field trip or provided beyond reality experiences offering access to the field site from an elevated perspective using pseudo-aerial 360° imagery. Results show that students with access to the elevated perspective had significantly better scores, for example, on their spatial situation model (SSM). Our findings provide first results on how an increased (geographic) scale, which is accessible through an elevated perspective, boosts the development of SSMs. The reported study is part of a larger immersive education effort. Inspired by the positive results, we discuss our plan for a more rigorous assessment of scale effects on both self- and objectively assessed performance measures of spatial learning.

DOI: https://doi.org/10.1007/978-3-030-23089-0_1
Immersive technologies have entered the mainstream. To establish them firmly in educational curricula requires both practical and empirical assessments that ultimately lead to best practice and design recommendations. We report on a study that contributes to both. To enrich geoscience education, we developed an immersive virtual field trip (iVFT) that we evaluated in previous small-scale studies. In order to make it accessible to larger audiences we (a) developed a version of the iVFT for mobile devices (Oculus Go); and (b) used an evolving public VR infrastructure at The Pennsylvania State University. The results of an empirical evaluation are insightful in that they show that system characteristics are only partially predicting learning experiences and that required mainstream adoption, that is, making immersive experiences mandatory for all students in a class, still has its challenges. We discuss the results and future developments.

Resilience and resistance concepts have broad application to ecology and society. Resilience is an emergent property that reflects the amount of disruption a system can withstand before its structure or organization uncharacteristically shift. Resistance is a component of resilience. Before the advent of intensive forest management and fire suppression, western North American forests exhibited a naturally occurring resilience to wildfires and other disturbances. Using evidence from ten ecoregions, spanning forests from Canada to Mexico, we review the properties of these forests that reinforced those qualities. We show examples of multi-level landscape resilience, of feedbacks within and among levels, and how conditions have changed under climatic and management influences. We highlight geographic similarities and differences in the structure and organization of historical landscapes, their forest types, and in the conditions that have changed resilience and resistance to abrupt or large-scale disruptions. We discuss the regional climates’ role in episodically or abruptly reorganizing plant and animal biogeography, and forest resilience and resistance to disturbances. We give clear examples of these changes and suggest that managing for resilient forests is a construct that is strongly dependent on scale and social values. It involves human community adaptations that work with the ecosystems they depend on and the processes that shape them. It entails actively managing factors and exploiting mechanisms that drive dynamics at each level as means of adapting landscapes, species, and human communities to climate change, and maintaining core ecosystem functions, processes, and services. Finally, it compels us to prioritize management that incorporates ongoing disturbances and anticipated effects of climatic changes, to support dynamically shifting patchworks of forest and nonforest. Doing so will make these shifting forest conditions and wildfire regimes more gradual and less disruptive to individuals and society.

The availability and quantity of remotely sensed and terrestrial geospatial data sets are on the rise. Historically, these data sets have been analyzed and quarried on 2D desktop computers; however, immersive technologies and specifically immersive virtual reality (iVR) allow for the integration, visualization, analysis, and exploration of these 3D geospatial data sets. iVR can deliver remote and large-scale geospatial data sets to the laboratory, providing embodied experiences of field sites across the earth and beyond. We describe a workflow for the ingestion of geospatial data sets and the development of an iVR workbench, and present the application of these for an experience of Iceland’s Thrihnukar volcano where we: (1) combined satellite imagery with terrain elevation data to create a basic reconstruction of the physical site; (2) used terrestrial LiDAR data to provide a geo-referenced point cloud model of the magmatic-volcanic system, as well as the LiDAR intensity values for the identification of rock types; and (3) used Structure-from-Motion (SfM) to construct a photorealistic point cloud of the inside volcano. The workbench provides tools for the direct manipulation of the georeferenced data sets, including scaling, rotation, and translation, and a suite of geometric measurement tools, including length, area, and volume. Future developments will be inspired by an ongoing user study that formally evaluates the workbench’s mature components in the context of fieldwork and analyses activities.

Carbon stocks and biodiversity of coastal lowland forests in South Africa: implications for aligning sustainable development and carbon mitigation initiatives

DOI: 10.1080/17583004.2019.1620035
Indigenous forests represent South Africa’s smallest biome, yet they are critical spaces for aligning sustainable development goals with carbon mitigation activities and conservation. The objectives of this study were to quantify the productivity and biodiversity of coastal lowland forests in the Dwesa Cwebe nature reserve in the Eastern Cape Province and characterize how estimates differed among alternative allometric equations. Using a complete tree census across six plots in the reserve, a total of 1489 trees were inventoried in 2011 and again in 2016. Aboveground tree carbon averaged 99.8 Mg C ha−1 (range 77.2–126.9 Mg C ha−1) using locally derived equations and 214.6 Mg C ha−1 using generalized equations. Tree aboveground net primary productivity averaged 1041.8 g C m−2 y−1. Forty-eight tree species were identified, including many species important to the livelihoods of local communities for medicinal, ceremonial, and other provisioning services. Overall, this study shows that current conservation activities are concomitant with high tree productivity and high levels of C stocks and biodiversity, including species of local and regional significance. Sustaining forest productivity and biodiversity in the future will be critical for maintaining ecosystem services and enhancing stewardship of forest resources in the region.

The North Atlantic-Arctic boundary is highly variable due to the transports of heat and moisture through the Gulf Stream and polar jet stream. The North Atlantic storm track generally follows the Gulf Stream and terminates near southeast Greenland and Iceland as the Icelandic Low. The Icelandic Low is the main driver of the North Atlantic Oscillation, particularly during winter months as the baroclinic zone expands to lower latitudes, correlating with temperature and precipitation in many areas around the North Atlantic. Understanding how atmospheric circulation, temperature, and precipitation changes in this region is important to build robust projections of how these variables will change, especially under natural and anthropogenic forcings. Here, climate proxies correlating to the Icelandic Low, summer air temperature, and annual precipitation build an understanding of how these variables changed over the last 2000 years. Through the natural climate shifts of this period — Roman Warm Period, Dark Ages Cold Period, Medieval Climate Anomaly, and Little Ice Age — it is shown that storm frequency decreases as temperature increases and the Icelandic Low increases in pressure (i.e., becomes weaker). However, these climate changes are not simultaneous, and their amplitudes are not similar across the region. Keeping regionality rather than a pan-Arctic average better explains natural variability of each sub-region and how each sub-region has evolved climatically due to anthropogenic forcings of greenhouse gases.

Why We Still Need Maps: Purple Lizard Charts Recreation in the Mid-Atlantic

Our group of four are spread across a grassy helicopter pad in southwestern Pennsylvania’s Ohiopyle State Park. We are at a familiar place for many of the one-and-a-half million annual visitors to Ohiopyle, the back of a parking area at the takeout of the Lower Youghiogheny River, known as Old Mitchell Place. Yet at the moment we are having a difficult time figuring out where we are supposed to go.

“So, that’s Sugar Run Trail there, and here at a right angle should be Mitchell,” says Michael Hermann, founder and lead cartographer of Purple Lizard Maps, as he points to our intended target on the state park trail map. It should be within our site. Yet on a sunny spring day, with young green just starting to sprout, our trailhead is nowhere to be seen. We wander further north along the parking area and eventually find the Mitchell Trail. Hermann makes a note of the discrepancy – a difference of roughly a hundred yards – then we continue on the trail.

Unraveling the Ethnoterritorial Fix in the Peruvian Amazon: Indigenous Livelihoods and Resource Management after Communal Land Titling (1980s-2016)

Tubbeh, R. & Zimmerer, K.
Journal of Latin American Geography
doi:10.1353/lag.0.0114
During the past several decades, Latin American governments have increasingly recognized indigenous peoples’ rights to cultural difference and channeled their territorial claims by titling their lands as common property. This “territorial turn” is supported by narratives about indigenous peoples as stewards of the environment. Geographic areas associated with indigenous land titling have increased since the late 1980s. This article presents research based on a case study of present-day livelihoods and resource management in two titled comunidades nativas [native communities] in the Peruvian Amazon. Our research finds that these communal lands have become spaces of dependency, depletion of natural resources, and territorial precarity rather than autonomy and sustainability. In spite of legal title, community members endure the tension between protecting their lands and negotiating their common property rights with outsiders as a strategy for income-earning through the exploitation of gold and timber. These conditions—driven by the encroachment of extractive economies and exacerbated by new road construction—provide new evidence about the contradictory dynamics of the “ethnoterritorial fix” in Latin America. These insights are potentially important for indigenous rights organizations in Latin America that consider territorial control as part of their strategies for the reproduction of indigenous peoples’ cultures, the security of their livelihoods, and the pursuit of autonomy.

Past, present and future of Online Geospatial Education at Penn State celebrated

Here is something to think about: Some of Penn State’s current Department of Geography students weren’t even born when Online Geospatial Education at Penn State offered its first class. While online classes are now considered normal, for the educators who launched these distance education courses in the late 1990s, it was a novel and risky venture.

Do Wastelands Exist? Perspectives on “Productive” Land Use in India’s Rural Energyscapes

Jennifer Baka
RCC Perspectives
http://www.environmentandsociety.org/perspectives/2019/2/article/do-wastelands-exist-perspectives-productive-land-use-indias-rural
Jennifer Baka looks at energy cultivation in India through an analysis of two energy development programs. The Social Forestry Programme and the National Mission on Biodiesel supported the development of “wastelands” by transitioning from biomass to biofuel. Their aim was to generate energy, and revitalize rural communities by providing them with energy security. However, Baka shows that the government’s failure to acknowledge the importance of wastelands to rural dwellers’ livelihoods resulted in dispossession, energy shortages, and job losses. These programs ultimately failed due to the disconnect between government conceptions of land-use improvement and existing local land-use practices.

Environmental Knowledge Cartographies: Evaluating Competing Discourses in U.S. Hydraulic Fracturing Rule-Making

Jennifer Baka, Arielle Hesse, Erika Weinthal & Karen Bakker
Annals of the American Association of Geographers
DOI: 10.1080/24694452.2019.1574549
In this article, we evaluate competing environmental knowledge claims in U.S. hydraulic fracturing (HF) regulation. We conduct a case study of the Bureau of Land Management’s (BLM) rule-making process over the period from 2012 to 2015, which was the first attempt to update federal oil and gas regulations in thirty years. Our study addresses a gap in the energy geographies and environmental governance literatures, which have yet to evaluate systematically HF-related decision-making processes at the policymaking scale. We mobilize theoretical insights from science and technology studies on boundary objects and critical environmental discourse analysis to conduct a “cultural cartography” of the BLM’s rule-making process. Our analysis of a subset of 1.4 million public comments submitted to the BLM, combined with fifteen stakeholder interviews, focuses on (1) who participated in the rule-making process; (2) the types of knowledge claims advanced in support or opposition of the rule; and (3) how these claims affected the rule-making process. In contrast to recent literature that finds increased “horizontality” of environmental knowledge production, we find a clear hierarchy that privileges government knowledge—including federal government–sponsored research and existing laws—above all other categories of evidence cited. As such, we argue that government knowledge—which in this case brought disparate stakeholder groups together to debate HF regulation—functions as a key boundary object in the rule-making process. We conclude with a discussion of implications for both research and policy.

Study finds global action needed to ensure acceptable climate futures

Ensuring a tolerable climate future, one that reduces warming while considering the costs, requires immediate global action, according to an international team of scientists.

“The study analyzes climate change as a multi-objective problem,” said Klaus Keller, professor of geosciences and an associate in the Earth and Environmental Systems Institute at Penn State. “Considering only a goal of tolerable temperature changes misses important aspects. One also needs to consider goals such as tolerable costs and impacts.”

Penn State offering faculty workshop on Ethics of Climate Change course

In order to expand the impact of the course, Penn State’s Office for General Education and the Sustainability Institute will offer a two-day training workshop May 9-10 for faculty members from across the Commonwealth interested in bringing the course to their campuses. Participants will have an opportunity to work with the original designers of the course as well as with climate change experts, such as Michael Mann, director of Penn State’s Earth System Science Center.

The workshop is open to faculty members of any rank from every campus, including University Park. Participants receive a small amount of supplemental pay and individualized guidance that will extend beyond the two-day workshop. Meals and housing are covered and there is no registration fee.

Agrobiodiversity: Integrating Knowledge for a Sustainable Future

Karl S. Zimmerer, Stef de Haan
MIT Press
https://mitpress.mit.edu/books/agrobiodiversity
Wide-ranging environmental phenomena—including climate change, extreme weather events, and soil and water availability—combine with such socioeconomic factors as food policies, dietary preferences, and market forces to affect agriculture and food production systems on local, national, and global scales. The increasing simplification of food systems, the continuing decline of plant species, and the ongoing spread of pests and disease threaten biodiversity in agriculture as well as the sustainability of food resources. Complicating the situation further, the multiple systems involved—cultural, economic, environmental, institutional, and technological—are driven by human decision making, which is inevitably informed by diverse knowledge systems. The interactions and linkages that emerge necessitate an integrated assessment if we are to make progress toward sustainable agriculture and food systems.

This volume in the Strüngmann Forum Reports series offers insights into the challenges faced in agrobiodiversity and sustainability and proposes an integrative framework to guide future research, scholarship, policy, and practice. The contributors offer perspectives from a range of disciplines, including plant and biological sciences, food systems and nutrition, ecology, economics, plant and animal breeding, anthropology, political science, geography, law, and sociology. Topics covered include evolutionary ecology, food and human health, the governance of agrobiodiversity, and the interactions between agrobiodiversity and climate and demographic change.

Vegetation succession in an old-growth ponderosa pine forest following structural restoration with fire: implications for retreatment and maintenance

US Forest Service, Pacific Southwest Research Station

Stand changes brought on by fire exclusion have contributed to reduced resilience to wildfire in ponderosa pine forests throughout the western US. Growing recognition of how structural attributes influence resilience has led to interest in restoring more heterogeneous conditions once common in these forests, but key information about interactions between stand and fuel development in such stands is currently incomplete or lacking. Few contemporary examples of structurally restored old-growth ponderosa pine forest exist. We re-measured plots in the Beaver Creek Pinery (BCP), a remote site in the Ishi Wilderness on the Lassen NF in California, that were installed following a 1994 wildfire, to better understand forest and fuel succession over time. The BCP experienced four wildfires since 1900 that restored the structure to one believed similar to historical ponderosa pine forest. Stand-scale change in overstory and understory vegetation were quantified in 2016 by remeasuring and remapping six one hectare plots that were initially mapped in 2000, and landscape-scale change was evaluated by remeasuring circular plots systematically arranged across the BCP in 1998. Tree recruitment, mortality, and growth were measured and changes in tree group and gap size and structure were calculated. We also examined the relative performance of California black oak, a declining but important species valued by tribes for food and wildlife for habitat, to better understand how fire interval and severity maintain the conifer and oak mixture. Using data from the re-measurement, we modeled stand and fuel development over the next 30 years using the Forest Vegetation Simulator (FVS),in order to predict the type of fire and return interval that would be necessary to maintain the desired heterogeneous structure over time.

Environmental Perception, Sense of Place, and Residence Time in the Okavango Delta, Botswana

Amelia C. Eisenhart, Kelley A. Crews Meyer, Brian King & Kenneth R. Young
The Professional Geographer
DOI: 10.1080/00330124.2018.1501709

Integral to the geographic discipline are cross-cultural analyses, many of which use languages outside of the researcher’s own. There are few analyses, however, that address issues of translation that are inherently geographic; namely, that language is understood as a manifestation of place and culture. This article argues that the results of environmental interviews must be interpreted through a lens that evaluates how the translation of a word, or even a concept, is understood differentially based on one’s sense of place. Interviews were conducted in three of the Etsha villages situated in the Okavango Delta, Botswana, comparing perceptions of changes in both the local area and the flooding regime. Findings show qualitatively and quantitatively how residents perceive environmental change in light of their residential histories and their production of place. These results highlight that environmental change in an area is perceived in the context of previous residences, including the length of time spent in residence and the environmental characterization of that place. The process of interviewing regarding such change, especially when translation is necessary, should therefore proceed by incorporating inquiries about previous residences and the environments of those areas to correctly contextualize environmental change in a particular area.
