The history of the environmental movement-from environmentalism of the nineteenth century to the environmental justice struggles of the late twentieth century-has often been portrayed as a series of efforts led by white environmentalists. In Stewards of the Land, Stevie Ruiz reassesses the movement and reveals that it has always been a multiracial endeavor. From Southern California berry fields to Japanese American concentration camps, from Chinese cooks in national parks to Chicano Civilian Conservation Corps workers, Ruiz traces how the racialized labor and environmental knowledge of Asian migrants and Chicana/o communities built the material foundations of modern environmentalism.

Stewards of the Land: Race and Reclaiming Environmental Labor in the American West (UNC Press, 2026) argues that environmental justice was never just a reaction to pollution in the 1970s but has a much longer history tied to land theft, labor exploitation, and the everyday struggles of frontline communities to live and work with dignity. Drawing from comparative ethnic studies and archival research and with a commitment to decolonial praxis, Ruiz recovers the stories of those who labored-often invisibly-to build, maintain, and reimagine environmental spaces in the American West.

Stevie Ruiz is a Professor of Chicana and Chicano studies at California State University, Northridge and a historian, author, and environmental justice scholar. 
His research focuses on the intersection of labor, immigration, and the American environmental movement — the work of building, maintaining, and stewarding the land that is so
often left out of the story. For more information about his work, see his website.

Kalani Foster is a PhD candidate at the University of Manchester whose research focuses on the intersection between biodiversity conservation, data and technology, and coloniality. For more information, and ways to contact him, see his research profile.

Who has the “right” to learn Mandarin Chinese? In Multiracial Mandarin: Asian Americans and Impossible Language (U Minnesota Press, 2026), Dr. David Shuang Song examines how matters of race and privilege shape US Mandarin language education and who has access to it. Through a two-year ethnographic study of two Bay Area high schools where diasporic and heritage speakers learn Mandarin alongside Black and Latinx students, Song advances a sociological and educational–linguistic inquiry into how language interacts with our understanding of identity and equity.

Comparing classroom activities in two public schools, Dr. Song investigates teachers who seek to make Mandarin accessible while detaching it from its cultural roots. As he explores the difficulties of limited resources, racial inequality, and pedagogical practices inherent in multiracial Mandarin instruction, Dr. Song shows how language education complicates how educators understand Asian American students and troubles conventional conversations around race and racial equity in schools.

Arguing that language practice and instruction must always be considered in relation to diaspora, ethnicity, and racialization, Multiracial Mandarin offers a frank analysis of the risks and benefits of teaching a diasporic language and asks if this practice ought to be replicated in more schools. As he applies innovative conceptual frameworks for talking about language among Asian Americans, Dr. Song’s timely and theoretically sophisticated analysis has wide-ranging implications for how students, teachers, and administrators approach essential questions around education, privilege, and language survival.

This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars. You can find Miranda’s interviews on New Books with Miranda Melcher, wherever you get your podcasts.

Kelly Lytle Hernández joins Michael Stauch to discuss how the US immigration system has always been “racist by design.” Many Americans’ understanding of the immigration system begins with the Chinese Exclusion Act of the late nineteenth century. In Racist by Design: Two Centuries of U.S. Immigration Control (Norton, 2026), Lytle Hernández expands that history by a full century, showing how the Haitian Revolution of the 1790s inspired not only America’s first immigration bans (to prevent news of a free Black republic from reaching our shores) but also its first refugee resettlement program (to welcome and support Haiti’s evicted enslavers.) She explains how Chinese Exclusion led the Supreme Court to disconnect immigration laws from the constitution. She reveals how eugenicists and Jim Crow segregationists built much of our current immigration regime as expressly "whites-only," and shows how during the Civil Rights Movement, Congress amended this system but never abolished it, leaving many of the regime’s racist rules and rituals intact today.

Highlights include:

- How an “Exclusion Quartet” of rulings by the Supreme Court in the late 19th century “unhinged” the Constitution from immigration policy;

- How the “family reunification” clause of the 1965 Immigration and Nationality Act, meant to favor European migrants, combined with global instability in the 1970s and ‘80s to create an enormous wave of non-white immigrants to the United States;

- What changed (and didn’t change) in immigration policy during World War II and the Cold War;

- How guestworker programs, asylum restrictions, and the US “visa dome” contribute to the racist-by-design immigration regime;

- How immigrants and their advocates have long used cracks and loopholes in immigration legislation to create space for themselves in the United States.

Guest: Kelly Lytle Hernández is a Professor in the Departments of History, African American Studies, and Urban Planning at UCLA where she also holds the Thomas E. Lifka Endowed Chair of History. She is one of the nation’s leading experts on race, immigration, and mass incarceration, and the author of the award-winning books Migra! A History of the U.S. Border Patrol (University of California Press, 2010), City of Inmates: Conquest, Rebellion, and the Rise of Human Caging in Los Angeles (University of North Carolina Press, 2017), and Bad Mexicans: Race, Empire, and Revolution in the Borderlands (W. W. Norton, 2022).

Host: Michael Stauch is an associate professor of history at the University of Toledo and the author of Wildcat of the Streets: Detroit in the Age of Community Policing, published by the University of Pennsylvania Press in 2025.
