The availability of accurate meteorological data is important for the modeling of atmospheric flows, enabling the understanding of climate change in a given environment over time. Therefore, this study aimed to evaluate the quality of the meteorological data of 2 m temperature (T) and mean sea level pressure (MSLP), obtained through the atmospheric reanalysis models ERA5 and ERA-Interim (ERA-i) in

Supercell thunderstorms are often associated with severe weather conditions, such as tornadoes, hail, strong wind gusts, and heavy rainfall, bringing about potentially significant consequences to populations and assets. Despite potential impacts, a lack of publicly available data has hindered the analysis and characterization of supercell climatology in Spain. We address this problem through a volunteered

Location-aware technologies and big data are transforming the ways we capture and analyze human activities. This has particularly affected tourism geography, which aims to study tourist activities within the context of space and places. In this study, we argue that the tourism geography of cities can be better understood through the time use of tourists captured by fine-grained human mobility observations

In the context of current decolonial geographical debates calling for action-oriented approaches to changing geographical knowledge construction, we propose cuerpo-territorio as a way to achieve this goal in Anglophone feminist geography. In Anglophone geography, emotions and embodiment have been studied through a range of ethnographic methods. There are intrinsic limitations of verbal and written

This article examines the factors shaping the perception of climate change and the relationship between climate change perception and migration. Drawing on a 691-case survey of climate perceptions in Cambodia, it explores three dimensions of climate change perception. The first is the relationship of climate change perceptions to space, geography, and scale. Second is the influence of livelihoods to

The connections between time and space have been studied considerably in quantitative and qualitative research on the geographies of care; however, researchers tend to prioritize one approach over the other. Our article integrates analyses of activity spaces and space–time paths with conceptualizations of care developed in qualitative studies to deepen understanding of the spatiotemporal care routines

As replicability and reproducibility (R&R) crises develop within emerging convergent inquiry, ethical use of provenance information is central to the establishment and preservation of trust in critical applications of GIScience and geospatial technologies. Today large volumes of geospatial data are generated at high velocity from satellite sensors and unmanned aircraft systems, citizen sensors, geolocation-based

Reproducible research is often perceived as a technological challenge, but it is rooted in the challenge to improve scholarly communication in an age of digitization. When computers become involved and researchers want to allow other scientists to inspect, understand, evaluate, and build on their work, they need to create a research compendium that includes the code, data, computing environment, and

The article begins with a historical account of Hudson’s rural settlement theory and the various attempts to replicate Hudson’s research. Harvey’s exhortation “by our theories you shall know us” is discussed as a motivation for replication. Motivations not considered are the detection of fraud, mendacity, and incompetence, because these are the domain of reproducible research. Replication research

The availability and use of geographic information technologies and data for describing the patterns and processes operating on or near the Earth’s surface have grown substantially during the past fifty years. The number of geographic information systems software packages and algorithms has also grown quickly during this period, fueled by rapid advances in computing and the explosive growth in the

The debate concerning replicable scientific research has reached geography’s shores. This has exposed old fault lines in our discipline, because some forms of geographical inquiry are more amenable to replicability than others. If there is a corner of the discipline that seems especially ill-suited to replicability, it is critical human geography. Almost no work in the subfield exhibits the combination

This article situates the current discussion of reproducibility and replicability taking place across the sciences within geographers’ enduring discussion of nomothetic and idiographic approaches, best exemplified by the Hartshorne–Schaefer debate. Although the Hartshorne–Schaefer debate retrospectively set the stage for the development of geography from the 1950s to the present, it is surprising that

This introduction provides a brief review of the motivation, background, and context of the Forum. It explains the roles of the six papers in the Forum and the importance of reproducibility and replicability across the broad sweep of contemporary geographic research.

The well-known modifiable areal unit problem (MAUP) has received much attention for a long time. There still exists, however, no unified understanding and solution to the MAUP. There is not even a statistic that quantifies the effects of the MAUP. This article proposes a new metric, namely, spatial aggregation entropy (SAE), based on which the spatial heterogeneity and uncertainty of aggregated data

We use examples from the European theater in World War II to argue that the assumption that combat is typically chaotic yields only limited insight into the large-scale evolution of military operations. To do this we examine the Ardennes campaigns of 1940 and 1944 in the context of explanatory devices used in physical geography such as complexity, nonlinearity, and emergence. We show that during the

The interpretive body has been overlooked in geopolitical scholarship despite its central role as a linguistic and cultural intermediary in geopolitical knowledge production and transmission. Interpreting comprises multiple acts designed to capture, represent, and reproduce geopolitical knowledge in all of its uncertain complexities. Drawing on assemblage thinking and embodiment, this article exposes

Anthropogenic climate change will disproportionately affect equatorial regions and closely adjacent areas, referred to here as the Fateful Ellipse. The vulnerability of these regions is exacerbated by a lack of capital for adaptive measures against the impacts of climate change. The increasing transference of capital from governmental control to private hands, and the increasing concentration of such

This research investigates the spatiotemporal dynamics of shoreline change and associated population impacts in deltaic Bangladesh. This region is among the world’s most dynamic deltas due to monsoon precipitation that drives tremendous discharge and sediment volumes from the Ganges–Brahmaputra–Meghna drainage basin. Theoretically, it draws on the concept of adaptive cycles that theorizes systems transitioning

The authors assessed eight years of a national professional development institute focused on providing geographic information systems (GIS) teaching and technical skills for educators, titled Teachers Teaching Teachers GIS (T3G). Through a survey (N = 276 [out of a total population of 450]), the authors determined that the institute generally met its goals of equipping educators so that they could

This article examines the implications of perceptions of an emergent crisis of flood risk for property rights in Jakarta. Jakarta faces devastating future floods due to climate change and other anthropogenic impacts, and the city has experienced severe flood events in recent years. State actors have responded with an aggressive infrastructural agenda that has led to evictions of numerous low-income

The formation of the American Association of Geographers (AAG) Geography and Military Study Committee by the AAG Council in April 2017 and the submission of the report by the Committee to Council in February 2019 were important events for the discipline. Yet, to date, the Committee’s report has received very little attention or comment. This article provides a critical analysis, focusing on the report’s

Tropical and subtropical plantation agriculture has been shown to be compatible with the conservation of biodiversity, but the specific practices, conditions, and farmer strategies associated with such diversity remain poorly understood. In the ecologically rich region of India’s Western Ghats, specifically, farm-scale tree species diversity is a key structural condition explaining avian diversity

We provide new insights on land use and climate change in human–environment dynamics of the equatorial Andes. We focused on two provinces (Cotopaxi and Napo) and three communities of Ecuador characterized by similar land tenure regimes but different socioenvironmental contexts. We integrate satellite data classifications and statistical analyses, longitudinal downscaled climate modeling, and interviews

As we progress into the Anthropocene, rising temperatures have amplified evaporative demand and rendered heat-induced drought stress, or hotter drought, as the hallmark of climate change moving forward. It remains unknown, however, whether upper treeline environments have been affected. For this study, we grouped previously published and unpublished data from study sites within the southern Rocky Mountains

In the Anthropocene, the charge to address climate change has been taken up by youth. From the landmark climate lawsuit filed in 2015 by twenty-one young people to secure the legal right to a safe climate to the thousands of climate marches and school strikes that took place in 2018 and 2019, young people are making their voices heard. Many undergraduate students enter universities passionate about

There have been calls to broaden urban theory to incorporate learnings from the Southern or ordinary cities (periphery). These calls are often placed as a counter to the hegemony of the Northern cities (metropolis), which have long been the sites for producing theory. If the metropolis is a concept to describe clustering of power and knowledge, then geographical located-ness of this metropolis in the

What happens after deportation? What contexts must Mexican deportees navigate and contend with after removal from the United States? This article explores the challenges for people postremoval in Mexico, particularly by drawing on fieldwork conducted in Tamaulipas, which is home to the Zetas drug trafficking organization and the infamous massacre of seventy-two migrants. We argue that incidental exposure

Location and geometric form constitute a fundamental basis for the characterization of objects in space. The traditional distance-based geographical analysis of objects, however, usually ignores information associated with their forms. In this article, we propose a location-and-form-based distance to simultaneously take into account these basic characteristics. For substantiation, the significance

This article argues that geographers must study the power of words as integral parts of human–environment relationships, with particular attention to local meanings, to intervene more effectively in the Anthropocene. Words are important tools by which people come to understand environmental changes and develop plans to facilitate mitigation and adaptation or, alternatively, to postpone these responses

The outcome of the 2016 presidential election in the United States was partly influenced by factors such as social marginalization and anti-immigrant sentiment, both of which have been associated with the global rise in far-right voting (FRV) outcomes. Sociological hypotheses such as group threat and group contact have been suggested as potential contextual factors in the relationship between immigrant

Drawing from early modern and contemporary geographic thought, this article explores how the premise of an Anthropocene (Age of Humans) can be used to reinforce enduring modes of human–environment thinking. Anthropocene dialogues build on insights posed by geographers of the eighteenth and early nineteenth centuries: unity of nature, humans as nature made conscious, humans as nature’s conscience, and

The Anthropocene is marked not only by significant environmental changes massively distributed in space and time but also by a substantial proliferation of scientific data. From Intergovernmental Panel on Climate Change reports to growing extinction lists, there is neither a shortage of environmental crises nor data to serve as official evidence of crises. As crucial as these data are, however, questions

For the last twenty years, scholarly research has relied primarily on food deserts as a way to frame geographic disparities in access to healthy foods. The results of this research have been empirically mixed, and the term itself has been critiqued as apolitical. Using the alternative framing of retailer redlining, I analyze the rapid growth of dollar stores in twenty-seven metropolitan areas in the

Each week, thousands of Mexican nationals living in northern Mexican border cities cross the border into the United States with nonimmigrant visas to “donate” blood plasma at commercial collection centers in exchange for a prepaid Visa gift card (valued at up to US$50). For these individuals, many of whom work on maquiladora assembly lines, a single donation can nearly double their weekly wages. If

This article examines an online protest to develop a contextual interpretation of geospatial big data and to challenge the debates on post-truth. In 2016, in support of the local protests against a crude oil pipeline passing through the region, social media users around the world remotely checked in to the Standing Rock Indian Reservation in North Dakota using a technique that we call location spoofing

Community resilience is commonly held to be critical for coping with adversity and disturbance. Although the process of community resilience is often contested and critiqued, the enactment of social relations within communities has been shown to ameliorate the worst impacts of disaster events on the well-being of their members. Here, we propose that well-being in the aftermath of disasters is shaped

This article mobilizes a decolonial critique of the Anthropocene. It argues for a certain epistemic disobedience to what, conceptually and politically, the Anthropocene seeks to legitimate. The article counterposes recent critical and global governance epistemologies, which summon the Anthropocene as a new humanist and statist moment for universal politics, against plural, parochial forms of relational

This article examines the shifting ways in which the dispossessive and toxic effects of agricultural chemicals have been encoded as agrarian best practices. I develop the concept of agrarian racial regimes, based on the work of Cedric Robinson, to examine how constructed hierarchies of human worth are made central to the sale and usage of chemicals. A focus on the politics of pesticides in the Mississippi

Since September 2012, the Jamaican coffee industry has been grappling with the coffee leaf rust (CLR) epidemic caused by the fungal pathogen Hemileia vastatrix. The first widespread outbreak affected more than one third of coffee plants across the island, resulting in millions of dollars in lost revenues for the sector. The emergence and spread of the disease have been linked to a confluence of factors

The Anthropocene affects how we manage the environment in many ways, perhaps most importantly by undermining how past conditions act as baselines for future expectations. In a period when historical analogues become less meaningful, we need to forge new practices and methods of environmental monitoring and management, including how to categorize, manage, and analyze the deluge of environmental data

The University of Michigan Department of Geography was discontinued in 1982, after a grueling review process that saw the discipline’s necessity very publicly called into question. Despite the fact that Michigan’s department was central to most of twentieth-century academic geography’s major intellectual movements, it was also the first in a series of major department closures in the early to mid-1980s

Using gestion différenciée in Geneva, Switzerland, as a case study, this article puts the politics of labor at the center of a political ecological analysis of efforts to “ecologize” the design and maintenance of urban parks. The article first highlights how the neomanagerial scripting of an “ecological” mode of managing urban parks reshapes social configurations of work by increasing the uneven distribution

Economic geographers have largely shown concern about the interaction between extractive industries and local economies by studying how lead firms create economic linkages with national firms. From a global production networks approach, this work looks to deepen the understanding of interfirm dynamics in extractive industries. This work has a critical position over previous research, however, because

Although a number of studies have developed fast geographically weighted regression (GWR) algorithms for large samples, none of them has achieved linear-time estimation, which is considered a requisite for big data analysis in machine learning, geostatistics, and related domains. Against this backdrop, this study proposes a scalable GWR (ScaGWR) for large data sets. The key improvement is the calibration

In this article, we examine how urban resilience has emerged as a global urban policy project, offering solutions for cities about how they can adapt to and recover from shocks and stresses, particularly those associated with climate change. We conceptualize this as a multicentric global urban resilience complex, catalyzed until recently by the Rockefeller Foundation’s 100 Resilient Cities initiative

The academic discipline of geography, faced with increasing competition from cognate fields and declining undergraduate enrollments, continues to suffer an identity crisis. In recent decades, many geography programs have instituted department or degree name changes, or otherwise rebranded, without any evidence guiding these decisions. This study begins to build an evidence base for these decisions

Geographers and environmental scientists use conceptual models to understand ecological processes and support management decisions. Most of these models are based on short-term experiments and field observations, which might not account for longer term forces that shape ecosystems over decades to centuries. How can scholars use historical sources and methods to improve conceptual models of ecological

The North American Great Lakes influence surface weather downwind, distinctly in winter when southward migrating cold air passes over relatively warm lakes. Study of the synoptic atmospheric patterns favorable for lake effects has focused on lake-effect snowfall, the most impactful effect of the lakes. Although the patterns are conducive to lake effects, they might not actually yield discernible modification

The Anthropocene concept stimulates much debate among geographers. This wider conversation often neglects the role that visual imagery plays in shaping geographical imaginations of the Anthropocene. This article examines artist Hannah Rothstein’s revisionist collection National Parks 2050 to better understand the intersections of visual imagery and the Anthropocene. Rothstein’s collection draws on

Although species have always shifted their ranges, the rapid pace of current biophysical changes and the further complications imparted by human land use provide unprecedented challenges for biodiversity conservation. As a result, goals, methods, and strategies are being reconceptualized. For example, the terms conservation and wilderness protection, and their associated practices, seem to be static

Recent years have witnessed an increasing use of big data in mobility research. Such efforts have led to many insights on the travel behavior and activity patterns of people. Despite these achievements, the data veracity issue and its impact on the processes of knowledge discovery have seldom been discussed. In this research, we investigate the veracity issue of mobile signaling data (MSD) when they

This work advances the critical urban studies literature on “planetary urbanization” by emphasizing the everyday struggles experienced by the people who live in and through planetary transformations. Specifically, we empirically investigated people in eastern Montana who experienced the intensive and extensive oil and gas production of the Bakken Boom via interview and survey data. In the process,

As a new wave of infrastructure expansion takes place globally, there has been a parallel turn to infrastructure in geographical research. This article responds to recent calls within this research for less human-centered engagement with the infrastructure turn. More specifically, this article aims to destablize anthropocentric discussions about infrastructural violence and infrastructural justice

Geographers are familiar with Ellsworth Huntington’s influential, yet frequently derided, claims about climatic determinism, eugenics, and the progress of civilization. His work on weather and mortality in New York City, a study conducted under the auspices of the National Research Council and with the extensive collaboration of New York–based life insurance companies, offers a different insight into

The biased population coverage and short temporal lengths of newly emerged data sets (e.g., data sets of social media, mobile phones, and smart cards) obstruct the effective analysis of long-term dynamics of landuse patterns, particularly in small and developing cities. This study proposed a framework to delineate and analyze mixed land-use patterns and their evolution using municipal water consumption

Despite advances in mapping technologies and spatial data capabilities, global mapping inequalities are not declining. Inequalities in the coverage, quality, and currency of mapping persist, with significant gaps in remote and rural parts of the Global South. These regions, representing some of the most economically and resource-disadvantaged societies in the world, need high-quality mapping to aid

We analyzed the migration consideration factors of residents from the Mississippi River Delta in southern Louisiana, which is under the influence of rising sea levels, subsiding land, and increasing flood risks. Through the use of a telephone survey of 1,125 adult individuals in twenty-four parishes, we gathered the demographic data and flood risk experiences and perceptions of each respondent. The
