Book Description
Despite the fact that fighting weeds was of paramount importance to the agricultural development of Canada, there has scarcely been any research on understanding the origins and history of these lowly plants. The War on Weeds in the Prairie West is the first full-blown environmental history of weeds in western Canada.

Book Description
Writing in Dust is the first sustained study of prairie Canadian literature from an ecocritical perspective. Drawing on recent scholarship in environmental theory and criticism, Jenny Kerber considers the ways in which prairie writers have negotiated processes of ecological and cultural change in the region from the early twentieth century to the present. The book begins by proposing that current environmental problems in the prairie region can be understood by examining the longstanding tendency to describe its diverse terrain in dualistic terms—either as an idyllic natural space or as an irredeemable wasteland. It inquires into the sources of stories that naturalize ecological prosperity and hardship and investigates how such narratives have been deployed from the period of colonial settlement to the present. It then considers the ways in which works by both canonical and more recent writers ranging from Robert Stead, W.O. Mitchell, and Margaret Laurence to Tim Lilburn, Louise Halfe, and Thomas King consistently challenge these dualistic landscape myths, proposing alternatives for the development of more ecologically just and sustainable relationships among people and between humans and their physical environments. Writing in Dust asserts that “reading environmentally” can help us to better understand a host of issues facing prairie inhabitants today, including the environmental impacts of industrial agriculture, resource extraction, climate change, shifting urban–rural demographics, the significance of Indigenous understandings of human–nature relationships, and the complex, often contradictory meanings of eco-cultural metaphors of alien/invasiveness, hybridity, and wildness.

Book Description
An exploration of the elaborate relationship between farmers, aerial sprayers, agriculturalists, crop pests, chemicals, and the environment. The controversies in the 1960s and 1970s that swirled around indiscriminate use of agricultural chemicals—their long-term ecological harm versus food production benefits—were sparked and clarified by biologist Rachel Carson’s Silent Spring (1962). This seminal publication challenged long-held assumptions concerning the industrial might of American agriculture while sounding an alarm for the damaging persistence of pesticides, especially chlorinated hydrocarbons such as DDT, in the larger environment. In Chemical Lands: Pesticides, Aerial Spraying, and Health in North America’s Grasslands since 1945 David D. Vail shows, however, that a distinctly regional view of agricultural health evolved. His analysis reveals a particularly strong ethic in the North American grasslands where practitioners sought to understand and deploy insecticides and herbicides by designing local scientific experiments, engineering more precise aircraft sprayers, developing more narrowly specific chemicals, and planting targeted test crops. Their efforts to link the science of toxicology with environmental health reveal how the practitioners of pesticides evaluated potential hazards in the agricultural landscape while recognizing the production benefits of controlled spraying. Chemical Lands adds to a growing list of books on toxins in the American landscape. This study provides a unique Grasslands perspective of the Ag pilots, weed scientists, and farmers who struggled to navigate novel technologies for spray planes and in the development of new herbicides/insecticides while striving to manage and mitigate threats to human health and the environment.

Book Description
"Presto! No More Pests!" proclaimed a 1955 article introducing two new pesticides, "miracle-workers for the housewife and back-yard farmer." Easy to use, effective, and safe: who wouldn't love synthetic pesticides? Apparently most Americans did—and apparently still do. Why—in the face of dire warnings, rising expense, and declining effectiveness—do we cling to our chemicals? Michelle Mart wondered. Her book, a cultural history of pesticide use in postwar America, offers an answer. America's embrace of synthetic pesticides began when they burst on the scene during World War II and has held steady into the 21st century—for example, more than 90% of soybeans grown in the US in 2008 are Roundup Ready GMOs, dependent upon generous use of the herbicide glyphosate to control weeds. Mart investigates the attraction of pesticides, with their up-to-the-minute promise of modernity, sophisticated technology, and increased productivity—in short, their appeal to human dreams of controlling nature. She also considers how they reinforced Cold War assumptions of Western economic and material superiority. Though the publication of Rachel Carson's Silent Spring and the rise of environmentalism might have marked a turning point in Americans' faith in pesticides, statistics tell a different story. Pesticides, a Love Story recounts the campaign against DDT that famously ensued; but the book also shows where our notions of Silent Spring's revolutionary impact falter—where, in spite of a ban on DDT, farm use of pesticides in the United States more than doubled in the thirty years after the book was published. As a cultural survey of popular and political attitudes toward pesticides, Pesticides, a Love Story tries to make sense of this seeming paradox. At heart, it is an exploration of the story we tell ourselves about the costs and benefits of pesticides—and how corporations, government officials, ordinary citizens, and the press shape that story to reflect our ideals, interests, and emotions.

Book Description
During the Second World War, as Canada struggled to provide its allies with food, public health officials warned that malnutrition could derail the war effort. Posters admonished Canadians to "Eat Right" because "Canada Needs You Strong" while cookbooks helped housewives become "housoldiers" through food rationing, menu substitutions, and household production. Ian Mosby explores the symbolic and material transformations that food and eating underwent as the Canadian state took unprecedented steps into the kitchens of the nation, changing the way women cooked, what their families ate, and how people thought about food. Canadians, in turn, rallied around food and nutrition to articulate new visions of citizenship for a new peacetime social order.

Book Description
Throughout history most people have associated northern North America with wilderness, abundant fish and game, snow-capped mountains, and endless forest and prairie. Canada's contemporary picture gallery, however, contains more disturbing images � deforested mountains, empty fisheries, and melting ice caps. Adopting both a chronological and a thematic approach, Laurel MacDowell examines human interactions with the land, and the origins of our current environmental crisis, from First Peoples to the Kyoto Protocol. This richly illustrated exploration of the past from an environmental perspective will change the way Canadians and others around the world think about � and look at � Canada.

Book Description
It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science’s development. The first analytical history of weed science to be written Compares the development of weed science, entomology and plant pathology Identifies the primary founders of weed science and describes their role
