The rapid expansion of the fishing industry in the last century has raised major concerns over the long-term viability of many fish species. International fisheries organizations have failed to prevent the overfishing of many stocks, but succeeded in curtailing harvests for some key fisheries. In Adaptive Governance, D. G. Webster proposes a new perspective to improve our understanding of both success and failure in international resource regimes.
In the second half of the twentieth century, worldwide attitudes toward whaling shifted from widespread acceptance to moral censure. Why? Whaling, once as important to the global economy as oil is now, had long been uneconomical. Major species were long known to be endangered. Yet nations had continued to support whaling.
Just south of San Francisco lies California's Salinas Valley, the heart of a multibillion dollar agricultural industry that dominates U. S. vegetable production. How did the sleepy valley described in the stories of John Steinbeck become the nation's "salad bowl"? In Cultivating Science, Harvesting Power, Christopher R. Henke explores the ways that science helped build the Salinas Valley and California's broader farm industry.
Scholars, scientists, and policymakers have hailed ecosystem-based management (EBM) as a remedy for the perceived shortcomings of the centralized, top-down, expert-driven environmental regulatory framework established in the United States in the late 1960s and early 1970s. EBM entails collaborative, landscape-scale planning and flexible, adaptive implementation. But although scholars have analyzed aspects of EBM for more than a decade, until now there has been no systematic empirical study of the overall approach.
Energy in Nature and Society is a systematic and exhaustive analysis of all the major energy sources, storages, flows, and conversions that have shaped the evolution of the biosphere and civilization. Vaclav Smil uses fundamental unifying metrics (most notably for power density and energy intensity) to provide an integrated framework for analyzing all segments of energetics (the study of energy flows and their transformations).
The vast majority of scientists agree that human activity has significantly increased greenhouse gases in the atmosphere—most dramatically since the 1970s. In February 2007 the Intergovernmental Panel on Climate Change found that global warming is "unequivocal" and that human-produced carbon dioxide and other greenhouse gases are chiefly to blame, to a certainty of more than 90 percent. Yet global warming skeptics and ill-informed elected officials continue to dismiss this broad scientific consensus.
Most of us are familiar with the terms climate change and global warming, but not too many of us understand the science behind them. We don’t really understand how climate change will affect us, and for that reason we might not consider it as pressing a concern as, say, housing prices or the quality of local education. This book explains the scientific knowledge about global climate change clearly and concisely in engaging, nontechnical language, describes how it will affect all of us, and suggests how government, business, and citizens can take action against it.
Tectonic faults are sites of localized motion, both at the Earth's surface and within its dynamic interior. Faulting is directly linked to a wide range of global phenomena, including long-term climate change and the evolution of hominids, the opening and closure of oceans, and the rise and fall of mountain ranges. In Tectonic Faults, scientists from a variety of disciplines explore the connections between faulting and the processes of the Earth's atmosphere, surface, and interior.
American agriculture has doubled its use of pesticides since the publication of Rachel Carson's Silent Spring in 1962. Agriculture is the nation's leading cause of non-point-source water pollution--runoffs of pesticides, nutrients, and sediments into streams, rivers, lakes, and oceans.
