Environmental sustainability issues in a fragile, semi-arid region and its coastal area, which experience climate changes from extreme drought conditions to the effects of hurricanes over a period of weeks to years, provide specific challenges for the ecosystems and the populations existing within the region. The research presented focuses on the problems and some solutions specific to the South Texas-Mexico border region, on both sides of the Rio Grande, focusing on water and air pollution.

Borders of Belonging investigates a pressing but previously unexplored aspect of immigration in America—the impact of immigration policies and practices not only on undocumented migrants, but also on their family members, some of whom possess a form of legal status. Heide Castañeda reveals the trauma, distress, and inequalities that occur daily, alongside the stratification of particular family members' access to resources like education, employment, and health care. She also paints a vivid picture of the resilience, resistance, creative responses, and solidarity between parents and children, siblings, and other kin. Castañeda's innovative ethnography combines fieldwork with individuals and family groups to paint a full picture of the experiences of mixed-status families as they navigate the emotional, social, political, and medical difficulties that inevitably arise when at least one family member lacks legal status. Exposing the extreme conditions in the heavily-regulated U.S./Mexico borderlands, this book presents a portentous vision of how the further encroachment of immigration enforcement would affect millions of mixed-status families throughout the country.

2020, Texas Historical Commission's Governor's Award for Historic Preservation was awarded to the Community Historical Archaeology Project with Schools (CHAPS) at the University of Texas Rio Grande Valley. This book grew out of the CHAPS program. Runner-up, 2019 Texas Old Missions and Forts Restoration Book Award, sponsored by the Texas Old Missions and Forts Restoration Association (TOMFRA) Long known as a place of cross-border intrigue, the Rio Grande’s unique role in the history of the American Civil War has been largely forgotten or overlooked. Few know of the dramatic events that took place here or the complex history of ethnic tensions and international intrigue and the clash of colorful characters that marked the unfolding and aftermath of the Civil War in the Lone Star State. To understand the American Civil War in Texas also requires an understanding of the history of Mexico. The Civil War on the Rio Grande focuses on the region’s forced annexation from Mexico in 1848 through the Civil War and Reconstruction. In a very real sense, the Lower Rio Grande Valley was a microcosm not only of the United States but also of increasing globalization as revealed by the intersections of races, cultures, economic forces, historical dynamics, and individual destinies. As a companion to Blue and Gray on the Border: The Rio Grande Valley Civil War Trail, this volume provides the scholarly backbone to a larger public history project exploring three decades of ethnic conflict, shifting international alliances, and competing economic proxies at the border. The Civil War on the Rio Grande, 1846–1876 makes a groundbreaking contribution not only to the history of a Texas region in transition but also to the larger history of a nation at war with itself.

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.
