Porter Published online: 26 September 2013 Springer Science+Business Media New York 2013 Abstract This article reports on an assessment of contemporary popular knowledge and perceptions of the American Dust Bowl of the 1930s. In a region prone to recurrent drought and evolving resource issues such as the depletion of the Ogallala Aquifer, it follows that knowledge of the Dust Bowl can contribute to understanding and dealing with contemporary and future challenges to the human–environment dynamic of the region. An age-stratified sample of residents from 93 Great Plains counties provided their understandings of the three Dust Bowl concepts (era, event, and region) via questionnaire. When compared with the academic record on the subject, significant variation between respondent age groups was identified. Successively, older generations of the historic Dust Bowl region maintain higher degrees of knowledge than their younger counterparts, regarding this exceptional chapter of American environmental history. This record of knowledge erosion not only speaks to the necessity of enhancing Dust Bowl educational resources, but can be utilized to underscore the salience of studying and documenting adaptive strategies to drought on the American Great Plains. Keywords Dust Bowl Great Plains Environmental perception Drought Introduction What was the Dust Bowl? The Dust Bowl was a period of severe drought accompanied by high winds and high temperatures; the impacts of which were exacerbated by the rapid expansion of agriculture on the American Great Plains in the 1920s and early 1930s. This resulted in recurrent, severe dust storms, economic J. C. Porter (&) Department of History, University of Arkansas at Little Rock, 2801 S. University Avenue, Little Rock, AR 72204-1099, USA e-mail: [email protected] 123 392 Popul Environ (2014) 35:391–416 ruin, and great human hardship. This convergence of geophysical and anthropogenic factors conspired to create what is arguably the most severe long-term human ecological crisis the USA has seen. The term ‘‘Dust Bowl,’’ as described above, is inherently ambiguous in that it refers to a phenomenon that can be considered discretely as an event, era, or region. More often, some amalgamation of historic and geographic analysis yields a multiconceptual construction of the Dust Bowl. As one explores the historiography of the Dust Bowl, it is apparent that the narrative of these concepts has evolved through time, presenting a shifting picture of this extraordinary chapter in America’s environmental history. This article first reviews the ways the Dust Bowl story has been told in order to provide contextual and comparative basis for the second part of the article, an assessment of the perceptions and knowledge of the general public today. Seeing how the public’s ideas parallel and/or diverge from the historical record speaks to an evolving understanding of the human–environment relationship on the Great Plains. The value of gaining insight into this relationship through the study of perception and knowledge is amplified by the realities of recurrent, and for that matter, contemporary drought in the Great Plains region coupled with changing Great Plains demographics (Bonnifield 1979; Hurt 1981; Worster 1979; Malin and Swierenga 1984). Increasingly, the cultural identity of residents of the Great Plains may not contain knowledge, let alone first-hand experience of the environmental hazards inherent to the region. The Dust Bowl to date: academic and popular sources The Dust Bowl event: what was the Dust Bowl? Academics, popular writers, and artists have contributed perspectives on this unique chapter of American history. Each source can exhibit significant variation in its objectives, its component emphasis, and, for that matter, its agenda. McDean’s (1986) Dust Bowl Historiography outlines the Dust Bowl’s ‘‘schizophrenic history’’ as he highlights the differences between the seminal works of Bonnifield (1979), Hurt (1981), and Worster (1979) among other lesser-known texts. McDean’s work conveys an exceptional range in topical material, writer approaches, and conclusions in regard to the Dust Bowl. Cronon’s (1992) discussion of opposing Dust Bowl narratives with a focus on Bonnifield (1979) and Worster (1979) deftly explains the variation that McDean (1986) identifies in terms of causal explanation. Cronon provides unparalleled insight into how multiple sources working with essentially the same data can produce dramatically different narratives of the Dust Bowl and its causes. Upward sweeping narratives, like Bonnifield (1979), present the Dust Bowl as a natural disaster that is overcome by the perseverance of individuals and communities alike. Human ingenuity, through the development of new technology, is the primary tool that helps people conquer the natural challenges of the Great Plains environment 123 Popul Environ (2014) 35:391–416 393 (Webb 1931). This story of improvement and accomplishment, referred to as the triumph narrative by Cronon (1992), is progressive in nature. On the other hand, the story Cronon (1992) calls the tragedy narrative is embraced by authors such as Worster (1979). With their genesis in the New Deal account of what transpired in the Great Plains in the 1930s, these declensionist stories of the Dust Bowl emphasize the human failure to adapt to the constraints of nature. Imported eastern farming techniques were ill-suited to the wide-open spaces of the Plains and fail miserably when drought inevitably returns. The removal of native grasses, with their soil-stabilizing root systems, to make way for wheat further sets the stage for disaster in this narrative. Many New Deal era authors suggested that the notion of humans triumphing over nature was not only false, but this hubris was the underlying cause of the Dust Bowl disaster. Both variants of the Dust Bowl story, as Cronon (1992, 1348) points out, are ‘‘inextricably bound to [their] conclusion, and the historical analysis derives much of its force from the upward or downward sweep of the plot.’’ For the texts that attempt to provide some holistic picture of the Dust Bowl event (those selected for this study) rather than more specialized work regarding individual facets of the phenomenon (e.g., drought, migration), one can imagine a Dust Bowl causation spectrum with an emphasis on human explanation on one side and climatological explanation (drought) on the other. Many of the ‘‘big picture’’ narratives exude a bias toward one explanatory pole or the other, while integrative narratives that critically consider both the contributory role of ‘‘natural’’ environmental factors and human agency represent a minority of these works. Hurt (1981) and Cunfer (2005) are noteworthy for their particularly lucid, evenhanded accounts of the event. The drought’s severity is detailed by Hurt, but not without first enlightening the reader to the commonplace nature of such events on the Great Plains. Unlike many of the texts that seemingly seek to assign blame to either farmers (characterized as ignorant), government bureaucrats (characterized as unsympathetic and detached actors), or an (unforgiving and unpredictable) Mother Nature, Hurt weaves together the contributory agents and circumstances to produce a holistic causal matrix. The reader is left with the impression that the Dust Bowl would not have happened if not for a unique and extraordinary intersection of diverse time and space elements. Cunfer’s (2005) geographic information system (GIS)-based methodology evaluates land use and climatological components of the Dust Bowl within the more objective analytical environment of GIS. The analysis suggests that drought and high temperatures played a greater role in creating the Dust Bowl than many authors have reported and explain the location of dust storms better than the landuse patterns of the day. Further analysis shows that land-use patterns have remained remarkably stable for the past century, thereby challenging both the stories of ecological disaster and agricultural triumph (Cunfer 2005). Worster’s (1979) text may be the most commonly cited source on the Dust Bowl. It falls to the more anthropogenic side of the causation spectrum. Worster describes the Dust Bowl as ‘‘The most severe environmental catastrophe in the entire history of the white man on this continent’’ as a result of capitalism’s impact on the soil of the Great Plains. It ‘‘was the inevitable outcome of a culture that deliberately, self- 123 394 Popul Environ (2014) 35:391–416 consciously, set itself to the task of dominating and exploiting the land for all it was worth’’ (1979, 4). Heaven’s Tableland (Johnson 1947) was the first comprehensive academic text dealing with the Dust Bowl and is representative of the first wave of Dust Bowl research. Johnson’s discussion relies heavily on the federal government’s document The Future of the Great Plains (Great Plains Committee 1936), which pointed to too much land being plowed up, cash crop farming, and wrong agricultural methods as the causes of the Dust Bowl. Johnson added unwise homesteading policies of the federal government, the costs of increased mechanization, land speculation, and the ‘‘mass attitude of the mind’’ that ‘‘men could conquer nature’’ as other contributory factors (Johnson 1947). Falling in the declensionist narrative camp, Johnson speaks of ‘‘the steps to rescue the Plains’’ that were taking form in 1937 via the federal government. To Johnson and others who have endorsed this perspective (e.g., Durbin 2002; Egan 2006; Lauber 1958; Heinrichs 2005), the Dust Bowl was a people problem to be solved wholly by the people. Although the influence of the New Deal narrative of human folly waned somewhat in subsequent decades as understanding of the drought increased, it continues to contribute heavily to contemporary works. Egan’s The Worst Hard Time (2006), a National Book Award winner, draws the conclusion that the government saved the Plains from total ruin. More recently, Ken Burns’ 2012 documentary The Dust Bowl aired on the Public Broadcasting System. This film was decidedly declensionist in its narrative of the event. The mood is set in the opening minutes of the film when the narrator describes the Dust Bowl as ‘‘the worst man-made ecological disaster in American history,’’ resulting from ‘‘the needless actions of thousands of farmers’’ (Burns 2012). The same spirit was evoked in Black Blizzard, a 2008 documentary broadcast on the History Channel (Bucher and Burke 2008). Both films drew heavily from The Worst Hard Time (2006). By contrast, however, The Weather Channel’s 2008 production of When Weather Changed History: Dust Bowl dedicated a significant portion of its content to explaining the air–sea dynamics embodied in the El NiñoSouthern Oscillation (ENSO), a phenomenon that can contribute to and/or intensify drought in the historic Dust Bowl region (Tyrrell 2008). Climatological evaluations of the Dust Bowl era (e.g., Broennimann et al. 2009; Burnette et al. 2010; Captondi and Alexander 2010; Cook et al. 2008, 2010; McCrary and Randall 2010; Nigram et al. 2011), particularly the impact of ENSO on the event, have become more common in recent years than ‘‘big picture’’ academic narratives (e.g., Bonnifield 1979; Worster 1979; Hurt 1981). While these more recent offerings have not overtly sought to tackle the anthropogenicclimatologic causation question and were not the focus of the literature reviewed here, they have contributed immeasurably to our understanding of the nature and severity of the Dust Bowl drought. Contemporary research is providing us with a much better understanding of climatological conditions in which to frame any future narrative of the Dust Bowl. With arguments such as the drought was ‘‘distinct from other droughts’’ (Broenniman et al. 2009) as a result of a unique combination of sea surface temperatures in both the Pacific Ocean and Caribbean Sea, it will be difficult to discount climatological factors in any consideration of the ‘‘cause’’ of the Dust Bowl. 123 Popul Environ (2014) 35:391–416 395 Beyond causation, the Dust Bowl migration is a central theme to most expansive Dust Bowl accounts. Not unlike the dueling narratives that Cronon (1992) identifies, the treatment of migration often exhibits an incongruent tone as well. Many Dust Bowl texts embrace either a story of abandonment or a story of sticking it out. There is considerable correlation between the abandonment and tragedy narratives as well as the sticking it out and triumph narratives. A flaw that is found in numerous texts, particularly juvenile literature, is to overgeneralize the numerous migratory flows that occurred across the central and southern USA in the 1930s as a result of drought and/or economic depression as ‘‘the Dust Bowl migration.’’ Perhaps the most well-known story regarding the Dust Bowl migration is told by Steinbeck (1939). However, as many authors have definitively illustrated (Clements 1938; Larson 1940; Skaggs 1978; Baltensperger et al. 1979; Bonnifield 1979; Hurt 1981; Pursell 1981; Worster 1979; Gregory 1991; Riney-Kehrberg 1991, 1994; Rathge and Highman 1998; Colin 2003; Rathge 2003; Egan 2006), the story of Dust Bowl era migration was a complex issue that had many more manifestations than the stereotypical trope of the Joad family following Route 66 to California. Many families persevered in their homes or stayed in the immediate region by migrating into nearby cities. As Riney-Kehrberg (1994) explains, much less has been told of the ways in which individuals and families adapted to the challenges of the 1930s without fleeing. The non-migration story may not be as romantic to some readers and certainly has not been as popular a theme in the body of Dust Bowlrelated literature. However, the treatment of this component of the Dust Bowl can have a powerful influence on one’s perception of the Dust Bowl event (Gregory 1991). Though the academic books and articles on the Dust Bowl are legion, one can only speculate about their influence on knowledge and perception of the general public. Meanwhile, the books that have been written for juvenile readers and stock the shelves of school libraries may provide a more realistic reflection of the information that has been transmitted to the public at large via textual materials. These books have often been penned by authors who are not experts on the subject and must tell the Dust Bowl story in less complex, more concise terms. The juvenile literature mirrors the academic texts in that a wide range of explanations along the causation spectrum are explored. Despite this range being present, there is a decided lean toward the New Deal narrative. Authors such as Lauber (1958) and DeAngelis and DeAngelis (2002) describe the Dust Bowl as an unparalleled event in American, and by Durbin’s (2002) account, global history, with humans squarely at fault. The Dust Bowl era: when was the Dust Bowl? As for the notion of a Dust Bowl era, it is difficult to attach definitive start and end years to such a complex phenomenon. While drought has been utilized as the primary temporal key (Bonnifield 1979; Stanley 1992; Cunfer 2005), it is important to remember that the Dust Bowl drought varied by location. Its inception, intensity, and duration were not uniform across the Plains. Therefore, depending upon the writer’s perspective and emphasis, there can be numerous ‘‘right’’ answers to the question of defining an appropriate temporal frame for the Dust Bowl. For example, 123 396 Popul Environ (2014) 35:391–416 some writers have focused on the Great Depression and the associated economic hardships as essential elements of the Dust Bowl era (Johnson 1947; King 1997; DeAngelis and DeAngelis 2002) while others have emphasized the changes in and applications of agricultural technologies (Floyd 1950; Meltzer 2000; Connell 2004; Cooper 2004) or the success or failure of crops (Raven and Essley 1997; Henderson 2001; Heinrichs 2005). Two examples tied to the success of crops include Low, who laments ‘‘1927 was the last of the good years in southeastern North Dakota’’ (1984, 1) while the protagonist of Hesse’s novel states, ‘‘We haven’t had a good crop in 3 years, not since the bounty of 31’’ (1999, 37). The frequency of dust storms has also been a factor in framing the Dust Bowl era. For example, Raven and Essley (1997) provide annual figures for dust storms in Guymon, Oklahoma, between 1933 and 1937 and virtually every text references April 14, 1935, also known as Black Sunday. On this day, the most notorious dust storm of the era swept across the Dust Bowl region and into surrounding states. The date is etched in survivors’ memories to the point that people in that region still recall exactly where they were and what they were doing when this symbol of the era occurred (Stallings 2001). Questions of when the Depression started, when the farmers transitioned from horse power to machine power, and when the rains ceased have numerous and nuanced answers that cannot be arbitrarily assigned to a single year. Even in the case of drought, one can define meteorological, hydrological, and agricultural variations. Furthermore, all of these elements can exhibit significant spatial variation. For example, the drought moved around from year to year and the hardships of the Great Depression actually arrived in the Dust Bowl region much later than the majority of the USA (Riney-Kehrberg 1994). The Dust Bowl region: where was the Dust Bowl? Despite McDean (1986) describing the geographic boundaries as the most basic characteristic of the Dust Bowl, varied regional representations have been utilized. Additionally, many accounts have not provided a map or merely described the region in vague terms. In academic literature that does offer a distinct regional definition, the most common representations are wholly or largely derived from wind erosion maps found in the National Archives (removed for review). These maps were the basis for Worster’s (1979) seminal map (Fig. 1). The difficulty of locating the Dust Bowl precisely on a map has been acknowledged explicitly by a minority of Dust Bowl authors (Bonnifield 1979; Worster 1979; Cooper 2004; Hansen and Libecap 2004), and detailed discussion of how one takes a complex phenomenon such as the Dust Bowl and neatly places it in a clearly defined geographic space is nearly absent. Worster (1979, 29) is a rare exception as he relates the transient and convoluted nature of the Dust Bowl region through statistics and anecdotes alike, before concluding that ‘‘wherever there were dust storms and soil erosion there was a Dust Bowl, and by that test, most of the Great Plains was ‘‘in it’’ during a part of the 1930s.’’ These tangible elements of soil erosion and dust storms can be joined by others such as migration and agricultural productivity to represent mappable elements of the event. Therefore, the Dust Bowl 123 Popul Environ (2014) 35:391–416 397 Fig. 1 Previously defined Dust Bowl regions is like other geographic regions, a complicated and fluid real world space that must be analyzed and simplified to be delineated. Have variables beyond erosion been included in the formulation of varying Dust Bowl regions? Variation is evident, but justification for regional boundaries is conspicuously absent in nearly every case. Exceptions include the works of Bonnifield (1979), Hurt (1981), and Worster (1979) and most notably, that of Cunfer (2005). Cunfer’s unparalleled geographic analysis of the Dust Bowl utilized geographic information systems to evaluate the role of key variables affecting 280 study counties in the greater Dust Bowl region. Soil type, percent cropland, percent difference from average rainfall, 5 year average rainfall, average March temperatures by year, and difference from average temperature by year are causal factors studied and mapped by Cunfer in his study. Considered alone, all of these variables portray slightly different Dust Bowl regions (Cunfer 2005). Fifty sources including academic texts, juvenile texts, Internet sites, and literature with a Dust Bowl focus were reviewed for their portrayal of the Dust Bowl region. Sources that were peripheral to the Dust Bowl were not included in the review. Twenty-eight of these sources included some form of map portraying the boundaries of the Dust Bowl. These maps varied widely in terms of thematic content, purpose, 123 398 Popul Environ (2014) 35:391–416 Dust Bowl terminology, sources cited, map projection employed, image resolution, and cartographic merit. The most readily apparent commonality is the high number of regions that exhibit nearly exact boundaries in the vicinity of the Texas and Oklahoma panhandles, southeastern Colorado, and western Kansas. These regions are those that have been based on the Worster/National Archive maps of the Dust Bowl (removed for review). Beyond this grouping of regions, another similarity can be noted. The western sides of the regions display more correlation than the eastern sides. The mean region size is 547,544 km2 with the largest region provided by Katzin’s (2002) area damaged by dust storms at 1,882,231 km2. For comparison, the area of the state of Oklahoma is 181,035 km2. Writers have placed the Dust Bowl in general agreement with the Great Plains, in states outside the Plains, or anywhere dust blew in the 1930s. This last association occurs when writers correlate all 1930s drought with the Dust Bowl (e.g., Katzin 2002). McDean claims that a major problem in locating the Dust Bowl has been this tendency of historians to fail to distinguish the Dust Bowl from other areas of drought (1986). These larger regions can also be explained by associating the Dust Bowl region with larger physiographic features such as the Great Plains or High Plains. In some cases, particular locations disproportionately influence the portrayal of the Dust Bowl region. For example, some associate Oklahoma with the Dust Bowl because of Steinbeck’s famous novel, The Grapes of Wrath. In that novel, the Joad family hails from Sallisaw, Oklahoma, and travels west along Route 66 to California. Geographically appropriate or not, these two features, a city and a road, permanently entered the Dust Bowl regional lexicon. Public understanding of the Dust Bowl Methodology To assess the Dust Bowl knowledge base of regional residents, a questionnaire that incorporated a series of evaluative Likert questions, open-ended questions, and a user-defined map of the Dust Bowl was administered to 372 citizens in the historic Dust Bowl region (as defined by Worster’s map). Respondents, required to be a current resident of the county, were obtained principally via opportunity sampling at the respective county courthouses. Additional sites such as municipal offices, public libraries, churches, parks, retail establishments, and nursing homes were utilized. The county courthouse was chosen as a starting point because it is usually located in the most populous community in the county. This is an important consideration in study area counties such as Kiowa County, Colorado (population 1,433), Greeley County, Kansas (population 1,258), and Harding County, New Mexico (population 704). Additionally, the courthouse is a gathering place for a wide cross-section of the community as they tend to a variety of administrative and civic responsibilities. In this case, stratified purposive sampling ensured that one respondent from each of four age groups (20–39, 40–59, 60–79, 80 and older) in each study county completed the questionnaire. 123 Popul Environ (2014) 35:391–416 399 Although the stratified purposive sampling for age was the guiding factor for respondent selection, demographic data collected from respondents illustrated that the sample contained a higher percentage of white and female respondents, was potentially more affluent, and was somewhat more educated than the study area averages. However, the sample was slanted toward the older inhabitants of the study area due to its age requirements. No one under the age of twenty was included, and half of respondents were over the age of fifty-nine. The older cohorts of the region are whiter just as the younger cohorts have the highest percentages of Hispanic persons. In other words, the race/ethnicity discrepancy suggested by Table 1 is not as noteworthy as it may appear at first glance. As for the gender discrepancy, this unequal proportion is partially explained by the combination of women being generally more receptive to participating as well as the disproportionately high number of females employed in county courthouses. A number of respondents chose not to respond to the household income question and several others expressed Table 1 Sample and study area demographics Sample Study area Population (n) 20–39 93 40–59 93 60–79 93 80? 93 Total 372 1,195,677 White 88.7 70.5 Hispanic 7.8 22.8 African American 0.5 3.8 Asian 0.5 1 Race/ethnicity (%) Native American 1.6 0.8 Other 0.5 1.1 Educational attainment (%) Less than high school 7 18 High school 29 28 Some college 44.9 29 Bachelors 14.5 16 Masters 3 7 PhD 1.6 2 100 100 Household income ($) Mean Income group mode 43,782 40,000–59,000 Gender (%) Male 40 49 Female 60 51 123 400 Popul Environ (2014) 35:391–416 confusion as to what household income represents upon completion of the questionnaire. As a result, the household income figures of Table 1 should be viewed with some skepticism. It is difficult to compare the study area’s household mean income to the sample. Nonetheless, the mode ($40,000–$59,000) of the sample is a range that includes the mean household income value ($43,782) for the study area. A number of respondents chose not to respond to the education question as well. In general, the two younger cohorts had higher levels of education than the two older cohorts. This proved interesting in light of the results discussed below. Hindsight provides the opportunity to comment on several methodological shortcomings of the research presented here. The aforementioned discrepancies between the sample and the study area demographics could be considered a shortcoming by some. A more consequential methodological shortcoming lies in the decision not to include ‘‘don’t know’’ along with ‘‘neither agree nor disagree’’ as a response choice to Likert statements. Some respondents reported that they ‘‘did not know’’ rather than not having an opinion. On the other hand, some respondents would discuss a Likert statement and determine they had ambiguous feelings or knowledge and respond with ‘‘neither agree nor disagree.’’ It would have been better if these two types of responses were calculated separately. And finally, several of the Likert statements could have been split into individual components. This was recognized as a potential issue when developing the questionnaire. However, in the interest of limited paper space, keeping the questionnaire length reasonable, and utilizing Cunfer’s (2004) statements verbatim, the decision was made to proceed with the questionnaire as designed. The problem was most prevalent with item C-10 (Item 1 on Fig. 3), ‘‘The Dust Bowl was defined by a combination of extended severe drought and unusually high temperatures.’’ Respondents commented that they were certain there was a drought, but not sure about the high temperatures. In these cases, some respondents marked ‘‘agree’’ instead of ‘‘strongly agree’’ or marked ‘‘neither agree nor disagree’’ because of the one part of the statement about which they were unsure. The Dust Bowl event: what was the Dust Bowl? The first Likert statements regarding the event address the basic causal dichotomy of the Dust Bowl (Fig. 2; Table 2). Why did the Dust Bowl happen? Was it the agricultural practices and/or the weather/climate that was responsible for the event? Summary and individual results illustrate that the two causal statements were not considered mutually exclusive by survey respondents. Beginning with summary Likert scores, all four age groups produced mean scores that fell between agreement and a neutral response to the statement ‘‘The Dust Bowl was a result of land mismanagement by farmers.’’ These results are interesting in light of two factors. First, agriculture remains a prominent component of livelihood in the study area. Despite the ever-present trend toward greater farm efficiency and subsequently decreased demand for farm labor, many if not most people in the study area have a direct or indirect connection to farmers, the group of people being assigned ‘‘blame’’ by the statement. In fact, 191 of 372 respondents (51.34 %) reported that they worked or had worked in the agricultural sector of the economy at one point 123 Popul Environ (2014) 35:391–416 401 Fig. 2 Dust Bowl causality Likert scores Table 2 Dust Bowl causality statistics Age group n x r r2 r The Dust Bowl was a result of land mismanagement by farmers 20–39 80 2.812 1.032 1.065 40–59 90 2.711 1.008 1.017 60–79 93 2.695 0.980 0.961 80? 93 2.606 0.941 0.885 356 2.702 0.987 0.974 Sample 0.066 The Dust Bowl was a result of severe drought 20–39 80 1.813 0.597 0.357 40–59 90 1.811 0.559 0.312 60–79 93 1.782 0.531 0.282 80? 93 1.702 0.525 0.276 356 1.775 0.552 0.304 Sample -0.154 during their lives. Second, this simple statement largely captures the spirit of the New Deal narrative of the Dust Bowl that has manifest in numerous historical and contemporary sources as discussed above. Perhaps this tepid support for a statement most historians would agree captures one part of the Dust Bowl causal matrix suggests rejection of an anthropogenic-based cause for the Dust Bowl and/or a reluctance to assign responsibility to the actions of one’s ancestors and fellow agriculturalists. Stronger agreement to the statement ‘‘The Dust Bowl was a result of severe drought’’ was documented. The sample mean score of 1.775 for this questionnaire item represented the highest level of agreement (lowest value) of any of the Likert items. Standard deviations were much lower for the drought item in all age subgroups as well. Within the region, it seems that the drought holds sway as the leading factor that led to the Dust Bowl. On both items, there was a stair-step progression toward stronger agreement with successively older respondents. Geoff Cunfer (2004) provides a series of six defining characteristics of the Dust Bowl. These six questionnaire items are generalized, fact-based statements and do not reflect the aforementioned tendency of some authors to present more anthropogenic-based causal explanations while others have emphasized the 123 402 Popul Environ (2014) 35:391–416 Fig. 3 Dust Bowl defining characteristics Likert scores physical/climatological factors. In other words, most Dust Bowl academics would agree with these distilled components of the phenomenon. Figure 3 illustrates the statements and the mean responses by age group to the defining Dust Bowl characteristics, while Table 3 presents a summary of statistical measures for each questionnaire item by age group. Of the six statements, the strongest agreement by all respondents was recorded for item 2 while the lowest level of agreement occurred with item 5, although the mean was still categorized as agreement. Item 1, ‘‘The Dust Bowl was defined by a combination of extended severe drought and unusually high temperatures,’’ had a mean score of 2.36 and exhibited considerable differentiation between the youngest age group and the three older groups. The youngest age group agreed more strongly with this statement. However, this may reflect a previously discussed problem with the survey instrument. The older respondents generally could not explicitly recall the temperature component of the event and thus were reluctant to agree with the statement. The dualistic nature of the statement had some impact on the results.

All age groups demonstrated agreement with this item, resulting in the third strongest level of support (1.994) for any one item on the questionnaire as well as the narrowest spread among age groups for any item. The two oldest age groups voiced the strongest support for this statement, while the 80 and older group exhibited the lowest standard deviation for any age subgroup for any one questionnaire item. For those that experienced the Dust Bowl firsthand, this is the defining characteristic that resonated most strongly. The dust storms and the quintessential Dust Bowl event, the epic Black Sunday dust storm, are emblematic of the Dust Bowl event. This may explain the high level of support across all groups. Sample-wide agreement with item 3, ‘‘The Dust Bowl was defined by agricultural failure, including both cropland and livestock operations’’ was strongest (1.966) of the six defining characteristics. The pattern among age groups for the previous statement regarding dust storms was repeated here. The oldest groups offered stronger agreement in comparison with the two younger age groups. The mean value for the 80 and older group (1.872) tied for the highest for any age group for any statement. The number of strongly agree responses increased incrementally with each age group. The general correlation between older respondents and stronger agreement evident in the preceding two statements is reversed on item 4. Younger residents of the region expressed slightly more unanimity in agreeing with the Dust Bowl being ‘‘defined by the collapse of the rural economy, affecting farmers, rural businesses, and local governments.’’ Discussions with respondents in the oldest subgroup suggested that they took issue with the term ‘‘collapse,’’ and thus, they were unlikely to select ‘‘strongly agree.’’ In fact, the dearth of strongly agree responses in all age groups despite the overwhelming agreement leads to relatively lower subgroup standard deviations for this item. However, the mean for all age groups of 2.124 combined with minimal variation between age groups and within age groups still indicates solid agreement with the statement. Item 5, ‘‘The Dust Bowl was defined by an aggressive reform movement by the federal government’’ elicited the weakest level of agreement (2.593) of the six defining characteristics. This statement also was responsible for producing the widest gaps among age groups, leading to the highest correlation value between older respondents and statement agreement of any item. In this case, the 80 and older age group voiced agreement in line with the previous four statements while the other age groups produced mean responses that were closer to neutral on the Likert scale. What explains this notable discrepancy between the age groups on this item? One thing that distinguishes this statement from the other five is the more general nature of this defining characteristic combined with the subjective term ‘‘aggressive.’’ To someone not familiar with the dramatic changes that were taking place in the federal government, particularly in regard to agricultural programs, the terms reform and aggressive could be confusing. Nonetheless, this statement did resonate with the oldest respondents. The significant decrease in neutral responses and increase in ‘‘agree’’ responses for the 80 and older group speaks to the lived experience of the 123 Popul Environ (2014) 35:391–416 405 older respondents. These people witnessed the creation of New Deal agencies such as the Works Progress Administration and legislation such as the Agricultural Adjustment Act of 1933 and the Soil Conservation and Domestic Allotment Act of 1935 that directly impacted their lives. These initiatives led not only to temporary make-work programs in the 1930s, but to enduring government agencies essential to productive livelihood on the Plains such as the Soil Conservation Service, as well as the inception of widespread farmer subsidies. Older respondents displayed the strongest agreement with the defining characteristic of migration, item 6. The twenty-five ‘‘strongly agree’’ responses were second only to the twenty-six associated with the 80 and older group for item 3. Additionally, several respondents commented that migration from rural areas into the cities of the region was much more common than out-of-region migration during the Dust Bowl era and therefore selected the neutral response. Therefore, the 80 and older subgroup’s level of support may have been markedly higher if the statement had been split into its two respective components. It is possible this problem affected the other subgroups too, as this item exhibits the highest standard deviation value for the sample as a whole. In summary, questionnaire respondents largely agreed with the six defining characteristics of the Dust Bowl. All six statements returned Likert means on the agreement side of the response spectrum. Strongest agreement for the sample as a whole occurred with items 2 and 3, pertaining to dust storm, wind erosion, and agricultural failure characteristics of the event. Among age groups, the strongest agreement to statements was provided by the 80 and older respondents for four of the six statements. A general pattern of stronger agreement with increasing age was also witnessed with the same four statements (2, 3, 5, and 6). This is most evident with items 5 and 6, tied to federal reform and migration, respectively. The Dust Bowl era: when was the Dust Bowl? The standardized collection of dates via the questionnaire creates the opportunity for comparative analysis of the Dust Bowl era in the mind of the public. The first notable pattern in the results is the disproportionate selection of 1930 and 1939 as beginning and end years of the event (Figs. 4, 5). This suggests that many respondents generalize the Dust Bowl to a decade-long event that corresponds with the 1930s or the ‘‘Dirty Thirties.’’ The notion of generalization to a decade-long concept of the Dust Bowl is also supported by the overwhelming number of responses that selected 1930 as the beginning year of the Dust Bowl. Most locations in the Dust Bowl region, however, did not experience the drought until 1931. The clear favorite for the concluding year is 1939, but by a lesser margin than 1930 was selected as the starting year. The spread of responses for ending years that stretch through the following decades of the 1950s and 1960s is noteworthy. This suggests that respondents may have been tying personal experiences of drought and dust to their reported end years. Very few respondents could relate personal experiences that predated 1930 whereas the dusty conditions of the 1950s were experienced by at least half of questionnaire respondents. 123 406 Popul Environ (2014) 35:391–416 Fig. 4 Respondent-defined Dust Bowl eras, 20–39 and 40–59 Comparison between the age groups shows that the range of responses progressively narrows with age (Table 4). In the 20–39 age group, 47 % of respondents tied the Dust Bowl era partially or wholly to years outside the 1930–1940 time frame, and the average duration of the event was nearly 11 years. By contrast, 13 % of the 80 and older group responses fall outside the same 11-year window. All of the responses on the 80 and older chart are at least partially in the 1930s. It is also noticeable that the spans are shorter, indicating a perceived Dust Bowl era that was more brief, as one progresses through the responses from young 123 Popul Environ (2014) 35:391–416 407 Fig. 5 Respondent-defined Dust Bowl eras, 60–79 and 80? to old. For example, the average duration for the 80 and older subgroup was 6.645 years. Not only do we see a clear relationship between age and duration of the event, but also with the year identified as the peak of the event. All four age subgroups produce an average that falls in 1934. However, the standard deviation for the youngest group is more than 16 years, while it is less than two for the oldest group of respondents. When the attention turns to examining the responses by state group, significant variation can also be noted. Kansas exhibits the most homogeneity within responses. With only a handful of exceptions, the uniformity in the Kansas responses across 123 408 Popul Environ (2014) 35:391–416 Table 4 Respondent-defined Dust Bowl era statistics Age group n x r r2 r Respondent-defined peak year of the Dust Bowl 20–39 75 1,934.507 16.366 267.848 40–59 90 1,934.452 12.669 160.511 60–79 93 1,934.817 6.472 41.889 80? 93 1,934.505 1.613 2.600 351 1,934.199 9.496 90.188 35.100 Sample 0.025 Respondent-defined length of the Dust Bowl era (years) 20–39 75 10.813 5.925 40–59 90 10.225 5.986 35.829 60–79 92 8.613 3.978 15.827 93 6.645 2.527 6.384 350 8.798 4.592 21.088 80? Sample -0.322 age groups is striking. Comparatively, Texas exhibits significant variation in beginning years and end years. A final observation pertains to the relationship between beginning year and duration. In general, respondents that provided later start years provided shorter eras for the Dust Bowl. If a respondent does not assign a start date of 1930, they are less likely to extend the Dust Bowl era to 1939 or 1940. Providing a beginning date that follows 1930 suggests more knowledge of the Dust Bowl phenomenon. Such an understanding may lead to these respondents providing an end date that correlates to improvements in local conditions or a specific element of the Dust Bowl phenomenon. The Dust Bowl region: where was the Dust Bowl? As discussed above, there is strong agreement among academic texts as to the area generally defined as the Dust Bowl. The variety of Dust Bowl regional depictions expands notably, however, when popular literature, juvenile texts, and Internet sources are included in the sample (removed for review). Considering that these sources play a complimentary role in some cases and likely supplant the academic sources in others, the Dust Bowl region could quickly become convoluted in the eye of the general public. Questionnaire respondents were asked to draw a closed line around the Dust Bowl region on a provided map. The map was 700 9 1000 and displayed the contiguous USA at a scale of 1:20,000,000. All states were labeled, and major rivers were shown, but not labeled. The North American Albers Equal Area Conic projection was utilized with the central meridian located at 96 west longitude and standard parallels at 20 and 60 north latitude. This projection utilizes the North American Datum of 1983 (NAD 1983). Maps were completed by 355 of 372 respondents. The remaining seventeen respondents were not familiar with the Dust Bowl and subsequently could not portray it on a map. Respondent maps were 123 Popul Environ (2014) 35:391–416 409 scanned at a resolution of 200 dots per inch to create a digital image that could be utilized with ArcMap GIS software. Scanned images were subsequently georeferenced, a process completed in ArcMap that aligned these images to a known geographic coordinate system (NAD 1983) to facilitate viewing and analysis (Wade and Sommer 2006). Following georeferencing, respondent polygons were on-screen digitized. In this process, respondents’ polygons were displayed on a computer monitor and traced by mouse to create a digital version of the polygon to be used for subsequent geospatial analysis and display. When viewed collectively, the hand-drawn regions demonstrate that the public identifies with the academic consensus of the spatial characteristics of the Dust Bowl. However, the individual Dust Bowl regions both parallel and diverge from academic norms. This reflects the fact that all inhabitants, with their different lived experiences, and ultimately their different interpretations of the event and its manifestation on the landscape will not perceive a Dust Bowl region with homogenous spatial characteristics. As J.B. Jackson stated, no region or ‘‘landscape can be exclusively devoted to the fostering of only one identity’’ (1984, 12). For example, physical features such as the Rocky Mountains as well as political boundaries like the Kansas/Nebraska border act as respective points of harmony for public geographic perceptions of the region. This illustrates how people can attach environmental meaning to both physical and cultural landscape elements. Despite individual respondent idiosyncrasies, as well as a more general collective agreement on the bounds of the region, responses grouped by age or location highlight some interesting differences. In general, the younger the respondent, the larger and more generalized their hand-drawn Dust Bowl region (Fig. 6). Many younger respondents identified the Dust Bowl region as being synonymous with the Great Plains and subsequently drew large symmetrical ovals over the central USA for their regional delineation. On the other hand, respondents from the 80 and older group often completed very detailed, non-symmetrical maps that were typically much smaller than those provided by younger groups. In fact, the average size of 80 and older respondent regions was approximately one-third that of 20–39 year olds. Responses on qualitative, open-ended questionnaire items from the oldest age group suggested more localized perceptions of the event that could lead to delineation of smaller Dust Bowl regions. Beyond providing regional area estimates more readily justifiable in comparison with the academic record, the 80 and older respondents generally placed their regions 50–100 km farther west than the other age groups. For Plains inhabitants the Dust Bowl happened where you live. From a state group perspective, regional bias is evident throughout the analysis of regional definition. For example, Texans’ regions are farthest south while Kansans’ regions are pulled north and east. Not surprisingly, Oklahoma’s regions are the most centrally located. This suggests that people associate the Dust bowl with the location to which they have the strongest sense of attachment to place. This is interesting in light of the comments that other researchers have made about the overwhelmingly negative connotation of the Dust Bowl (Bader 1988; Jordan 1978; Riney-Kehrberg 1994). From a spatial perspective, respondents did not hesitate to associate their home states with this inauspicious event. Rather, many respondents 123 410 Popul Environ (2014) 35:391–416 Fig. 6 Select Group Dust Bowl regions by age or location wore the Dust Bowl experience as a badge of their community’s perseverance and steadfastness. The Kansas and the 80 and older groups, from state and age cohorts, respectively, provided Dust Bowl regions that were judged to be the most congruent with the established academic consensus. Returning to view the respondent-defined region as a whole (Fig. 6), several interesting patterns emerge. First, the western edge of the region is much ‘‘harder’’ than the eastern edge. This indicates that respondents exhibited much more agreement regarding the western edge of the Dust Bowl region. This suggests that a physical feature, in this case the Rocky Mountains, acted as a feature of consensus 123 Popul Environ (2014) 35:391–416 411 for public geographic knowledge. Respondents may not have been able to define an exact western boundary, but they were able to recognize that the region did not expand over the Rockies and against the predominant atmospheric flow (the Westerlies) for that matter. On the opposite of the respondent-defined region, support for an eastern boundary is much more ambiguous. Support for including respective counties in the region fades slowly with increasing distance east. This distance decay is an appropriate reflection of the region and this researcher would argue a better way of representing the Dust Bowl region than most hard edge representations. Wind erosion, dust storms, and drought were generally experienced with decreasing severity as one moved eastward. As it is impossible to know what variables respondents utilized to construct their respective Dust Bowl regions, it is also impractical to know what sources have informed their knowledge base on the topic. Any number of popular and academic sources may also have contributed to the formation of Dust Bowl concepts in the minds of respondents. An example of how the regional concepts of the Dust Bowl could be influenced by outside sources includes Woody Guthrie’s folk music. Guthrie was a noteworthy voice of the Dust Bowl era and his 1940 album, Dust Bowl Ballads, chronicles the hardships of the time. One song on that album is titled The Great Dust Storm and it tells the story of the April 14, 1935 Black Sunday dust storm. In this song, Guthrie ticks off the geographic dimensions of the epic storm, beginning with the line ‘‘From Oklahoma City to the Arizona line…’’ (1940). In all likelihood, respondents’ spatial understanding is not based solely on one book or song or one classroom lesson, but rather an amalgamation of numerous sources. Discussion Principally academic, but also from popular culture, the voices contributing to our understanding of the Dust Bowl have presented a range of information related to the three Dust Bowl concepts. Dominant themes emerge including a preponderance of New Deal era accounts emphasizing the culpability of farmers to more recent and narrowly focused works which increasingly accentuate meteorological and climatological components of the phenomenon. The Dust Bowl remains a popular topic of study for academics and popular voices alike in the second decade of the twentyfirst century. Climatologists, in particular, try to uncover new insights into droughtdrivers (Burnette et al. 2010; Captondi and Alexander 2010; Cook et al. 2010; McCrary and Randall 2010; Nigram et al. 2011) and a new Ken Burns documentary on the Dust Bowl airing on the Public Broadcasting System in 2012 [with companion book (Duncan and Burns 2012) and website] provided the most recent mass media ‘‘big picture’’ explanation of the event. Meanwhile, this exploration of the degree to which public knowledge parallels academic norms in terms of the core elements of the Dust Bowl has revealed a strong relationship. In general, Great Plains residents agree with the key traits of the Dust Bowl as defined by Cunfer (2004). Nonetheless, significant variation was noted within the sample of study area residents. As a whole, respondents expressed stronger agreement with the academic consensus on the three biophysical statements 123 412 Popul Environ (2014) 35:391–416 (items 1–3) than the socioeconomic statements (items 4–6). This may be explained by the pervasive drought conditions affecting the study area at the time of questionnaire administration and/or the less value-laden nature of the biophysical statements in comparison with the socioeconomic statements. Respondents were generally more likely to express stronger agreement with both biophysical and socioeconomic as a function of increasing age. Respondents in the oldest age group (80 and older) were as young as three when the Dust Bowl commenced. While a number of the oldest respondents (particularly those older than 90) expressed firsthand memories of the Dirty Thirties, many spoke of the stories and experiences relayed by their parents and their parents’ peers. In many cases, this relayed information represented the primary source of their Dust Bowl knowledge. With each passing year, these first and even second generation familial sources diminish and any documentable Dust Bowl knowledge thus becomes less a product of shared, local memory. Similarly, the public knowledge paralleled the academic record to a higher degree in the northern half of the study area (north of 37 North latitude). This area was home to a higher percentage of respondents born within the study area, and subsequently a higher number of persons that know or have known Dust Bowl survivors. It was also the focus of a much publicized locally produced Dust Bowl documentary (Kinderknicht 2006) repeatedly broadcast in the area prior to administration of the questionnaire. Numerous respondents in northwest Kansas discussed Stories from the Dust Bowl during the course of questionnaire administration. The film may have played a role in the higher relative levels of Dust Bowl knowledge that were documented for this subregion. State educational standards also support the relatively higher public/academic knowledge correlation for the state of Kansas. The Kansas State Department of Education identifies the topic of the Dust Bowl as a high school knowledge and/or application indicator to support benchmark two (the student uses a working knowledge and understanding of individuals, groups, ideas, developments, and turning points in the era of the Great Depression through World War II in United States history) of the state history standard. The high school instructional suggestions for benchmark two include a comparison of The Grapes of Wrath to actual accounts of the Dust Bowl found in diaries, letters, or oral histories (Kansas State Department of Education 2005). On the topic of education, it is worth noting that due to large numbers of respondents not answering the question about educational attainment, calculations were not completed to determine any statistical relationship between educational attainment and Dust Bowl knowledge. However, for those that did report educational attainment, the oldest respondents proportionally had the lowest levels of education. In this case, it appears factors such as historical proximity to the event and all that goes with it (e.g., more likely to have been born in study area and have immediate family that lived through it and discussed it) trumped formal education for knowledge acquisition. When placing these results in a contemporary context, one must think about the demographics of the Plains. The oldest denizens of the region have witnessed the dramatic transformation of the Plains from a home to epic dust storms of the 1930s, and to a lesser degree the 1950s, into a land of verdant center-pivot irrigation fields 123 Popul Environ (2014) 35:391–416 413 that stay green via the waters of the Ogallala Aquifer. This is a very different visual reference point for today’s arrivals to the Plains. As Tuan (1974) points out, it can take a long time to know a place. The fact that the older generations have seen these changes take place speaks to their abilities to describe, map, and understand the Dust Bowl phenomenon (Jackson 1984) and their understanding that change can and will come again. Unfortunately, this research has documented an ongoing erosion of that accumulated knowledge. The decline is steady and dramatic among the four age groups sampled. As the most informed group of residents passes away in coming years, they are replaced with younger people who do not possess a comparable understanding of the complex event, era, and region. Conclusion Over the course of collecting the questionnaire data, the author was exposed to a remarkable group of Great Plains citizens, many holding on to personal and family stories of this unique chapter of American environmental history. Among the tales of the ever-present dust, those respondents who lived through the era spoke of abject poverty and hunger. That was not necessarily the worst of it for many of these people, however. Nine respondents in the oldest age group provided unsolicited commentary about losing one or more family members to the dust. Seven had siblings succumb to dust pneumonia and two more lost their fathers to automobile accidents occurring in dust storms. But in spite of these hardest of hard times, people somehow persevered. ‘‘Nobody went hungry in Clayton; they all looked out for each other,’’ stated the 80 and older respondent from Union County, New Mexico. ‘‘When the government was coming to kill the cattle, Dad turned them out so the poorer neighbors might have a milk cow,’’ explained a resident from Potter County, Texas. ‘‘Dad always tried to keep 10 acres of pinto beans growing for the community to use as needed.’’ A respondent from the 60–79 year old group in Moore County, Texas said, ‘‘My father ran a mercantile and he never turned anyone away. He had more than $150,000 out on credit when he was forced to close.’’ One of the author’s favorite stories came from the 80 and older respondent from Roosevelt County, New Mexico. She reported that her parents owned a grocery and neighbors would trade a chicken for their daily goods. ‘‘At night, mom would sneak out and return the chickens to the neighbors,’’ she said. These stories of hardship and examples of personal and community resiliency tell a story that statistics cannot convey. This underscores the need for documenting these human resources through oral history projects as well as the development of educational pathways that will supplement the invaluable words and experiences of a fading generation. They present the opportunity to contribute to understandings of varied adaptive strategies that are employed by households and communities in order to better prepare for future drought events. Research that focuses on these adaptive strategies in the context of climatic variability (e.g., McLeman 2006; McLeman et al. 2008; Orlove 2005) and diminishing resource bases (e.g., Parton et al. 2007) is enhanced by additional firsthand accounts such as these. But Great 123 414 Popul Environ (2014) 35:391–416 Plains-centric research agendas can also benefit and their necessity be underscored by the principal finding presented here. In sum, the regional knowledge base regarding what is arguably the USA’s most acute, long-term environmental disaster is in decline. Successively, younger generations are less aware of the Dust Bowl as historical distance from the event increases. Ongoing demographic change in the region may strengthen this pattern. Many counties in the historic Dust Bowl region have witnessed a significant influx of persons from outside the region in recent years (Haverluk and Trautman 2008). Interviews conducted for this research suggest that these new arrivals are principally in the youngest age category included in this research (20–39) and rarely have significant, if any, knowledge of the Dust Bowl. Thus, increased migration into the region may accelerate the decline in Dust Bowl knowledge, particularly for the younger age groups. In spite of the appearance of ‘‘conquering geography’’ in the region (Lewis 1979) by the application of center-pivot irrigation, the region’s documented history of widespread, long-term drought events suggests that it is a merely a matter of time until the next challenge is presented to human existence on the Great Plains. As the Dust Bowl becomes increasingly generalized, or entirely foreign, to residents of the region, the opportunity for making better decisions based on past experience is muted. When the uncertainties of climate change, increasing energy costs and groundwater depletion are considered as well, one wonders if the residents of the Great Plains can afford not to know their past. Previous research has illustrated unanimity for enhanced educational resources (removed for review) while the information presented here speaks to its necessity if future generations will be able to answer the question, ‘‘What was the Dust Bowl?’’ References Bader, R.
