Shifting Baselines: The Past and the Future of Ocean Fisheries. Jeremy B. C. Jackson, Karen E. Alexander, and Enric Sala, eds. Island Press, 2011. 284 pp., illus. $35.00 (ISBN 9781610910019 paper).Shifting Baselines: The Past and the Future of Ocean Fisheries is an attempt to investigate the feasibility and relevance of the idea introduced by Daniel Pauly of the University of British Columbia in his 1995 seminal paper “Anecdotes and the shifting baseline syndrome of fisheries.” This book is a collection of articles based on a conference held in 2003 at the Scripps Institution of Oceanography, and it claims to use a “historical perspective to determine the true magnitude of decline and the challenges for sustainability in the future.” Its overall objective is to show “how new perspectives on the past can alter our understanding of oceans today and change the future for the better.” The book first defines the problem—what we lose without marrying history to marine ecology—and then describes the many challenges of joining these two perspectives. Two sets of case studies are presented (one on sardines and anchovies, the other on cod), then a discussion follows on the methodologies used in historical marine ecology in all their variety and complexity and including their strengths and limitations. The book concludes by describing how historical ecology is, or could be, used today.
