GLOBEC, Focus 4 and SPACC… Manuel Barange, GLOBEC IPO. Plymouth Marine Laboratory, Prospect Place, Plymouth PL1 3DH, UK. M.barange@pml.ac.uk, www.globec.org
GOAL: “To advance our understanding of the structure and functioning of the global ocean ecosystem, its major subsystems, and its response to physical forcing so that a capability can be developed to forecast the responses of the marine ecosystem to global change”.
GLOBEC’s Objectives: • 1- To better understand how multiscale physical-environmental processes force large-scale changes in marine ecosystems • 2- To determine the relationship between structure and dynamics in a variety of oceanic systems which typify significant components of the global ocean ecosystem • 3- To determine the impacts of global change on stock dynamics using coupled physical, chemical and biological models linked to appropriate observation systems • 4- To determine how changing marine ecosystems will affect the global earth system by identifying and quantifying feedback mechanisms
GLOBEC FOCUSES ON ECOSYSTEM SCIENCE • …underpinned by the belief that understanding the role of variability in the functioning of marine ecosystems is essential to manage marine living resources.
… YET ASPIRES TO BE POLICY RELEVANT Reykjavik Declaration on Responsible Fisheries in the Marine Ecosystem (FAO 2001): signed by over 100 fishing nations and committing them to undertake research in pursue of Ecosystem-Based-Fisheries-Management … we will undertake to...: ...identify and describe the structure, components and functioning of relevant marine ecosystems, diet composition and food webs, species interactions and predator-prey relationships, the role of habitat and the biological, physical and oceanographic factors affecting ecosystem stability and resilience (in other words: GLOBEC research);

Small Pelagic Fishes and Climate Change (SPACC) The long-range goal is to forecast how the productivity of small pelagic fish populations will be altered by climate variability and change. SPACC will involve process studies, based on comparisons of standard measurements from different ecosystems, and retrospective studies built around palaeoecological and genetic data. Chairpersons : Claude Roy (France)/ Dave Checkley (USA)

GLOBEC Focus 4 Feedbacks from Changes in Marine Ecosystem Structure “To co-operate with other ocean, atmospheric, terrestrial and social global change research programmes to estimate feedbacks from changes in marine ecosystem structure to the global earth system”
GLOBEC Focus 4, Activity 4.3 • Social Impacts of Changes in Marine Ecosystems • Goals: • To understand the interactions between marine coastal communities and global changes in marine ecosystems; • To understand the capacity of these communities to adjust to these changes; • To understand the consequences of these adjustments for marine ecosystems.
Change in Marine Ecosystems Change in Fishing Communities • Climate variability • Internal ecosystem dynamics • Fishing • Habitat degradation • Pollution • Exotic species, new diseases • Environmental change • Demographic Change • Technological innovations • Law and property relations • Policy Change • Relations of production/reproduction, • Gender and ethnic relations • Shifting values • These interactions involve issues of: • Scale (of interaction, of adaptation, drivers vs responses…) • Values (of ecosystem state/ fisheries) • Knowledge (science versus management versus Local)
CLIMATE CHANGE + OVERFISHING Case study collapse of Atlantic cod stocks in Newfoundland and Labrador, Canada Consequences of changes: • Severe social disruption (fishery closures, plant closures, unemployment, reduced incomes, employment volatility, outmigration, shifts in property relations and power…)
Policy response (ADAPTATION) : • Fishing Moratorium on cod • Downsize fleet • Income replacement measures (incl. new quotas for alternative spp) • Thus contributing to further marine ecosystem change. Some Fishers Resilience (capacity to absorb change) Social response (ADAPTATION): • Fishing effort expands spatially and ecologically • Effort intensifies on traditional grounds • Effort shifts across species, down trophic levels Low Ecosystem Resilience
