This report indicates that climate change will significantly affect the availability and trade of fish products, especially for those countries most dependent on the sector, and calls for effective adaptation and mitigation actions encompassing food production.

Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face the threat of another great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

"Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.

America's commercial fisheries are in jeopardy. With a significant percentage of the nation's fisheries depleted and fish populations declining in many regions, the health of the broader marine environment is also threatened. What should be done to reverse the decline and restore fish populations is a matter of much debate. However, most experts agree that our fisheries are not being managed in ways that will ensure the steady employment of fishermen and that will provide a dependable future supply of seafood to consumers.There are those who believe that privatizing our fisheries is the best means to address the present crisis. The potential that privatization has to resolve a number of the problems currently plaguing our fisheries is undeniably attractive. However, as pointed out by prominent economists Seth Macinko and Daniel W. Bromley in Who Owns America's Fisheries?, unless certain key provisions are incorporated into IFQ programs, the health and stability of our fisheries are not only unlikely to improve, the deterioration of them may actually be accelerated.

This circular stems from a study carried out for FAO projects “Sustainable Fisheries Management and Biodiversity Conservation of Deep-Sea Living Marine Resources and Ecosystems in the Areas Beyond National Jurisdiction” (GCP/GLO/366/GFF) and “Deep-Sea Sponge Grounds Ecosystems of the North Atlantic: An Integrated Approach Towards their Preservation and Sustainable Exploitation” (GCP/GLO/679/EC). These projects included outputs related to the economic valuation of goods and services provided by the deep seas in areas beyond national jurisdiction. This study compiled an estimate of the total economic value (TEV) of the deep seas, which considered the provision of deep-water fish, the harvest of precious corals, the use of substances of marine origin as pharmaceuticals, the extraction of deep and ultra-deep oil and the potential mining of mineral resources from the seafloor, carbon sequestration carried out by the deep seas, the importance of scientific research in the deep seas, and touristic activities with submersibles to visit sites such as the Titanic shipwreck. Comprehensively, the TEV assessed for the deep-sea ecosystem as a whole is estimated at USD 267 billion per year. Ninety two percent of the economic value originates from abiotic resources (oil and minerals), 5 percent from biotic resources (fish, corals and pharmaceuticals of marine origin), 2 percent from cultural services (scientific research and tourism/recreation), and 1 percent from carbon sequestration.
