    Description: Global change is occurring now, often with consequences far beyond those anticipated. Although there is a wide range of assessment approaches available to address specific aspects of global change, there is currently no framework to identify what governance responses have worked and where, what has facilitated change, and what preventative options are possible. To respond to this need, we present an integrated assessment framework that builds on knowledge learned from past experience of responses to global change, to enable decision makers, researchers, managers and local stakeholders to: (1) make decisions efficiently; (2) triage and improve their responses; and (3) evaluate where to most effectively allocate resources to reduce vulnerability and enhance resilience of coastal peoples. This integrated assessment framework, IMBER-ADApT is intended to enable and enhance decision making through the development a typology of case studies providing lessons on how the natural, social and governance systems respond to the challenges of global change. The typology is developed from a database of case studies detailing the systems affected by change, responses to change and, critically, an appraisal of these responses, generating knowledge-based solutions that can be applied to other comparable situations. Fisheries, which suffer from multiple pressures, are the current focus of the proposed framework, but it could be applied to a wide range of global change issues. IMBER-ADApT has the potential to contribute to timely, cost-effective policy and governing decision making and responses. It offers cross-scale learning to help ameliorate, and eventually prevent, loss of livelihoods, food sources and habitat.

    Description: Ocean acidification, a consequence of rising anthropogenic CO2 emissions, is poised to change marine ecosystems profoundly by increasing dissolved CO2 and decreasing ocean pH, carbonate concentration, and calcium carbonate mineral saturation state worldwide. These conditions hinder growth of calcium carbonate shells and skeletons by many marine plants and animals. The first direct impact on humans may be through declining harvests and fishery revenues from shellfish, their predators, and coral reef habitats. In a case study of U.S. commercial fishery revenues, we begin to constrain the economic effects of ocean acidification over the next 50 years using atmospheric CO2 trajectories and laboratory studies of its effects, focusing especially on mollusks. In 2007, the $3.8 billion U.S. annual domestic ex-vessel commercial harvest ultimately contributed $34 billion to the U.S. gross national product. Mollusks contributed 19%, or $748 million, of the ex-vessel revenues that year. Substantial revenue declines, job losses, and indirect economic costs may occur if ocean acidification broadly damages marine habitats, alters marine resource availability, and disrupts other ecosystem services. We review the implications for marine resource management and propose possible adaptation strategies designed to support fisheries and marine-resource-dependent communities, many of which already possess little economic resilience.
