This environmental history of America’s largest estuary provides insight into how and why its former productivity and abundant fisheries have declined. The concept of “shifting baselines”—changes in historical reference points used in environmental assessments—illuminates a foundational challenge when evaluating the health of ecosystems and seeking to restore degraded wildlife populations. In this important book, Victor S. Kennedy examines the problem of shifting baselines for one of the most productive aquatic resources in the world: the Chesapeake Bay. Kennedy explains that since the 1800s, when the Bay area was celebrated for its aquatic bounty, harvest baselines have shifted downward precipitously. Over the centuries, fishers and hunters, supported by an extensive infrastructure of boats, gear, and processing facilities, overexploited the region’s fish, crustaceans, terrapin, and waterfowl, squandering a profound resource. Beginning with the colonial period and continuing through the twentieth century, Kennedy gathers an unparalleled collection of scientific resources and eyewitness reports by colonists, fishers, managers, scientists, and newspaper reporters to create a comprehensive examination of the Chesapeake’s environmental history. Focusing on the relative productivity and health of its fisheries and wildlife and highlighting key species such as shad, oysters, and blue crab, Shifting Baselines in the Chesapeake Bay helps readers understand the remarkable extent of the Bay’s natural resources in the past so that we can begin to understand what has changed since, and why. Such knowledge can help illustrate the Bay’s potential fertility and stimulate efforts to restore this pivotal maritime system’s ecological health and productivity.

The Chesapeake Bay is the nation’s largest estuary. After slow deterioration for several centuries, the Chesapeake Bay Program was launched in 1983 to restore it. After spending more than $24 billion, the results of the restoration program are disappointing. The Bay Program has arrested the decline of the Bay, but it has failed to achieve its restoration goals—something that will become more challenging with climate change. The rate of environmental change today is more rapid than at any time in the history of humanity. The concept of restoration—to return to an earlier time and condition—is an outmoded concept for coastal ecosystems like the Chesapeake Bay that are at the leading edge of change. A better strategy would be to focus on shaping the future Bay. While we cannot create the future Bay, we have many of the tools to shape it, tools that have never been used as a complement to existing efforts. Learn about the past and present of the Bay, how climate change will affect its future, and how we can intervene to shape the future of the Chesapeake.

Shifting Baselines explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems. Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public. While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.

The decades-long effort to protect one of the nation’s most important waterways The Chesapeake Bay is the largest estuary in the United States and the site of some of the most significant moments in the nation’s history. This book provides for the first time a comprehensive story of the effort to save and protect its waters and living resources for future generations. Andrew Ramey describes the enormous task—engaging the states in the Bay’s watershed and the federal government since 1983—to realize one of the largest, most complex, and most expensive ecosystem restoration projects ever undertaken. He also unfolds a dramatic political narrative, tracing the momentous changes in American environmental politics from the “green” heyday of the 1960s and 1970s to the environmental movement’s collision with the Reagan administration in the 1980s and the movement’s ultimate triumph over the anti-environmental backlash of the 1990s and early 2000s. Along the way, he clarifies assumptions about the environmental movement, the major parties’ roles in it, and our society’s efforts to forge sustainable relationships with the natural world. Saving the Chesapeake reveals how a campaign to rescue this crucial resource altered the course of American environmentalism.

This book explores a specific ecosystem in depth, in order to weave a story built on place and history. It incorporates the theme of a journey to help reveal the environment-human-health-food system-problem. While drawing on a historical approach stretching back to the American colonial era, it also incorporates more contemporary scientific findings. By crafting its story around a specific place, the book makes it easier for readers to relate to the content, and to subsequently use what they learn to better understand the role of food systems at the global scale.

Explores how two coastal ecosystems are responding to the pressures of human expansion The Northern Adriatic Sea, a continental shelf ecosystem in the Northeast Mediterranean Sea, and the Chesapeake Bay, a major estuary of the mid-Atlantic coast of the United States, are semi-enclosed, river-dominated ecosystems with urbanized watersheds that support extensive industrial agriculture. Coastal Ecosystems in Transition: A Comparative Analysis of the Northern Adriatic and Chesapeake Bay presents an update of a study published two decades ago. Revisiting these two ecosystems provides an opportunity to assess changing anthropogenic pressures in the context of global climate change. The new insights can be used to inform ecosystem-based approaches to sustainable development of coastal environments. Volume highlights include: Effects of nutrient enrichment and climate-driven changes on critical coastal habitats Patterns of stratification and circulation Food web dynamics from phytoplankton to fish Nutrient cycling, water quality, and harmful algal events Causes and consequences of interannual variability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Read a review of this book in Marine Ecology review of this book
