William R. Lowry - Böcker

By the turn of the millennium, it had become painfully apparent that the United States had made some serious misjudgments in its interactions with the natural world. The country's treasured national parks, while remaining immensely popular tourist destinations, were not immune to the damage. Preservation alone would no longer be enough; by this time, repair and restoration were necessary.Can the United States reverse the mistaken policies that severely damaged the crown jewels of its national park system? This thoughtful and hopeful book, in turns analytical and personal, investigates that critical question by focusing on four of America's most-loved public paces. In Repairing Paradise, William Lowry, an eminent expert on U.S. natural resource policy, details and assesses four ambitious efforts to reverse environmental damage in the national parks:• The reintroduction of wolves in Yellowstone• Reducing the impact of vehicle traffic in Yosemite• Restoring fresh water to the Everglades• Removing structural impairments to river flows in the Grand CanyonRepairing Paradise combines authoritative research with extensive personal experience. Lowry has spent time in all four of the parks—observing conditions, talking to the most informed decisionmakers, and taking photos. He deftly combines his field research with solid public policy analysis to paint an instructive portrait of the mission to restore the natural health and glory of some of the world's most wondrous places.

The politics of building dams and levees and other structures are just part of the policies determining how American rivers are managed or mismanaged. America's well-being depends upon the health of those rivers and important decisions go beyond just dam-building or dam removal. American rivers are suffering from poor water quality, altered flows, and diminished natural habitat. Current efforts by policymakers to change the ways American rivers are managed range from the removal of dams to the simulation of seasonal flows to the restoration of habitat, all with varying degrees of success. Efforts to restore American rivers are clearly delineated by William Lowry in "Dam Politics" as he looks at how public policy and rivers interact, examines the physical differences in rivers that affect policies, and analyzes the political differences among the groups that use them. He argues that we are indeed moving into an era of restoration (defined in part as removing dams but also as restoring the water quality, seasonal flows, and natural habitat that existed before structural changes to the rivers), and seeks to understand the political circumstances that affect the degree of restoration.Lowry presents case studies of eight river restoration efforts, including dam removals on the Neuse and Kennebec rivers, simulation of seasonal flows on the Colorado river, and the failed attempt to restore salmon runs on the Snake river. He develops a typology of four different kinds of possible change - dependent on the parties involved and the physical complexity of the river - and then examines the cases using natural historical material along with dozens of interviews with key policymakers. Policy approaches such as conjunctive water management, adaptive management, alternative licensing processes, and water marketing are presented as possible ways of using our rivers more wisely. "Dam Politics" provides a useful and systematic account of how American waterways are managed and how current policies are changing. American rivers are literally the lifeblood of our nation. Lowry has written a lively and accessible book that makes it clear as a mountain stream that it matters deeply how those rivers are managed.

Comparing national efforts to preserve public lands, William R. Lowry investigates how effectively and under what conditions governments can provide goods for future generations. Providing intergenerational goods, ranging from balanced budgets to space programs and natural environments, is particularly challenging because most political incentives reward short-term behavior. Lowry examines the effect of institutional structure on the public delivery of these goods. He offers a theoretical framework accounting for both the necessary conditions - public demand, political stability, and official commitment to long-term delivery - and constraining factors - the tensions between public agencies and politicians as well as between different levels of government - that determine the ability of a nation to achieve long-term goals. In support of this argument, Lowry evaluates data on park systems from more than one hundred countries and provides in-depth case studies of four - he United States, Australia, Canada, and Costa Rica - to show how and why the delivery of intergenerational goods can vary.For each of the cases, he reviews background information, discusses constraints on agency behavior, and assesses expansion of the park systems and restoration of natural conditions at specific locations. This extensive comparative analysis of the preservation of public lands offers new insights into the capability of nations to pursue long-term goals.
