In the 1930s and 1940s, rural reformers in the United States and Mexico waged unprecedented campaigns to remake their countrysides in the name of agrarian justice and agricultural productivity. Agrarian Crossings tells the story of how these campaigns were conducted in dialogue with one another as reformers in each nation came to exchange models, plans, and strategies with their equivalents across the border. Dismantling the artificial boundaries that can divide American and Latin American history, Tore Olsson shows how the agrarian histories of both regions share far more than we realize. He traces the connections between the US South and the plantation zones of Mexico, places that suffered parallel problems of environmental decline, rural poverty, and gross inequities in land tenure. Bringing this tumultuous era vividly to life, he describes how Roosevelt’s New Deal drew on Mexican revolutionary agrarianism to shape its program for the rural South. Olsson also looks at how the US South served as the domestic laboratory for the Rockefeller Foundation’s “green revolution” in Mexico—which would become the most important Third World development campaign of the twentieth century—and how the Mexican government attempted to replicate the hydraulic development of the Tennessee Valley Authority after World War II. Rather than a comparative history, Agrarian Crossings is an innovative history of comparisons and the ways they affected policy, moved people, and reshaped the landscape.

Winner, Abbott Lowell Cummings Award, Vernacular Architecture Forum, 2020 Winner, Elisabeth Blair MacDougall Book Award, Society of Architectural Historians, 2021 From the boundary surveys of the 1850s to the ever-expanding fences and highway networks of the twenty-first century, Border Land, Border Water examines the history of the construction projects that have shaped the region where the United States and Mexico meet. Tracing the accretion of ports of entry, boundary markers, transportation networks, fences and barriers, surveillance infrastructure, and dams and other river engineering projects, C. J. Alvarez advances a broad chronological narrative that captures the full life cycle of border building. He explains how initial groundbreaking in the nineteenth century transitioned to unbridled faith in the capacity to control the movement of people, goods, and water through the use of physical structures. By the 1960s, however, the built environment of the border began to display increasingly obvious systemic flaws. More often than not, Alvarez shows, federal agencies in both countries responded with more construction—“compensatory building” designed to mitigate unsustainable policies relating to immigration, black markets, and the natural world. Border Land, Border Water reframes our understanding of how the border has come to look and function as it does and is essential to current debates about the future of the US-Mexico divide.

Today, a new generation of farmers are working to heal both the land and agriculture's legacy of racism. In Healing Grounds, Liz Carlisle tells the stories of Indigenous, Black, Latinx, and Asian American farmers who are reviving their ancestors' methods of growing food--techniques long suppressed by the industrial food system. This, Carlisle shows, is the true regenerative agriculture: a holistic approach that values diversity in both plants and people. It has the power to combat climate change, but only if we reckon with agriculture's history of oppression. Through rich storytelling, Carlisle lays bare that painful history, while lifting up the voices of farmers who are working to restore our soil, our climate, and our humanity.

Abandoning Their Beloved Land offers an essential new history of the Bracero Program, a bilateral initiative that allowed Mexican men to work in the United States as seasonal contract farmworkers from 1942 to 1964. Using national and local archives in Mexico, historian Alberto García uncovers previously unexamined political factors that shaped the direction of the program, including how officials administered the bracero selection process and what motivated campesinos from central states to migrate. Notably, García's book reveals how and why the Mexican government's delegation of Bracero Program–related responsibilities, the powerful influence of conservative Catholic opposition groups in central Mexico, and the failures of the revolution's agrarian reform all profoundly influenced the program's administration and individuals' decisions to migrate as braceros.

A synthesis of the agricultural history of the Green Revolution The Green Revolution was devised to increase agricultural production worldwide, particularly in the developing world. Agriculturalists employed anhydrous ammonia and other fertilizing agents, mechanical tilling, hybridized seeds, pesticides, herbicides, and a multitude of other techniques to increase yields and feed a mushrooming human population that would otherwise suffer starvation as the world’s food supply dwindled. In The Green Revolution in the Global South: Science, Politics, and Unintended Consequences, R. Douglas Hurt demonstrates that the Green Revolution did not turn out as neatly as scientists predicted. When its methods and products were imported to places like Indonesia and Nigeria, or even replicated indigenously, the result was a tumultuous impact on a society’s functioning. A range of factors—including cultural practices, ethnic and religious barriers, cost and availability of new technologies, climate, rainfall and aridity, soil quality, the scale of landholdings, political policies and opportunism, the rise of industrial farms, civil unrest, indigenous diseases, and corruption—entered into the Green Revolution calculus, producing a series of unintended consequences that varied from place to place. As the Green Revolution played out over time, these consequences rippled throughout societies, affecting environments, economies, political structures, and countless human lives. Analyzing change over time, almost decade by decade, Hurt shows that the Green Revolution was driven by the state as well as science. Rather than acknowledge the vast problems with the Green Revolution or explore other models, Hurt argues, scientists and political leaders doubled down and repeated the same missteps in the name of humanity and food security. In tracing the permutations of modern science’s impact on international agricultural systems, Hurt documents how, beyond increasing yields, the Green Revolution affected social orders, politics, and lifestyles in every place its methods were applied—usually far more than once.

Farming across Borders uses agricultural history to connect the regional experiences of the American West, northern Mexico, western Canada, and the North American side of the Pacific Rim, now writ large into a broad history of the North American West. Case studies of commodity production and distribution, trans-border agricultural labor, and environmental change unite to reveal new perspectives on a historiography traditionally limited to a regional approach. Sterling Evans has curated nineteen essays to explore the contours of “big” agricultural history. Crops and commodities discussed include wheat, cattle, citrus, pecans, chiles, tomatoes, sugar beets, hops, henequen, and more. Toiling over such crops, of course, were the people of the North American West, and as such, the contributing authors investigate the role of agricultural labor, from braceros and Hutterites to women working in the sorghum fields and countless other groups in between. As Evans concludes, “society as a whole (no matter in what country) often ignores the role of agriculture in the past and the present.” Farming across Borders takes an important step toward cultivating awareness and understanding of the agricultural, economic, and environmental connections that loom over the North American West regardless of lines on a map. In the words of one essay, “we are tied together . . . in a hundred different ways.”

The familiar story of the Civil War tells of a predominately agricultural South pitted against a rapidly industrializing North. However, Adam Wesley Dean argues that the Republican Party's political ideology was fundamentally agrarian. Believing that small farms owned by families for generations led to a model society, Republicans supported a northern agricultural ideal in opposition to southern plantation agriculture, which destroyed the land's productivity, required constant western expansion, and produced an elite landed gentry hostile to the Union. Dean shows how agrarian republicanism shaped the debate over slavery's expansion, spurred the creation of the Department of Agriculture and the passage of the Homestead Act, and laid the foundation for the development of the earliest nature parks. Spanning the long nineteenth century, Dean's study analyzes the changing debate over land development as it transitioned from focusing on the creation of a virtuous and orderly citizenry to being seen primarily as a "civilizing" mission. By showing Republicans as men and women with backgrounds in small farming, Dean unveils new connections between seemingly separate historical events, linking this era's views of natural and manmade environments with interpretations of slavery and land policy.
