REGIONAL PROGRAMMES
Cod and Climate Change Programme (ICES-CCC)This programme investigates the effect of climate variability on cod stock fluctuations, ranging from the effects of small-scale turbulence on encounter rates between fish larvae and their prey, to large-scale effects of inter-decadal changes in wind fields on circulation and transport of heat and young fish.

Cod catches have followed environmental trends in recent decades. Has fishing
limited the capacity of cod to respond to favourable environments?
REGIONAL PROGRAMMES
Climate Change and Carrying Capacity (PICES-CCCC)This activity develops a theoretical and mathematical framework which extends the concept of carrying capacity into the multi-species ecosystem domain. It addresses how climate change affects ecosystem structure and the productivity of key biological species at all trophic levels in the North Pacific.

The community structure of the North Pacific has changed over the last decades. How is this affecting the functioning of the
system?
REGIONAL PROGRAMMES
Southern Ocean Programme (SO-GLOBEC)This programme is focused on understanding how physical forces influence population dynamics and predator/ prey interactions between key species.
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.

Focus 4
“Feedbacks from Changes in Marine Ecosystem Structure”
General Objective:
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
Working Group Goals:1) To understand the interactions between
marine coastal communities and global changes in marine ecosystems;
2) To understand the capacity of these communities to adjust to these changes;
3) To understand the consequences of these adjustments for marine ecosystems.

Interactions of Environmental and Societal Changes
Several issues complicate study of these interactions:
1. Scale• What are the scales at which marine ecosystems and coastal
communities interact?• What are the scales of environmental change compared with scales on
which humans have the ability to change and adapt.• How to move between scales when the drivers are global but the
impacts local?
2. Knowledge• Open” and “Closed” knowledge systems – e.g. publicly available, local
knowledge, or group-based. • How best to exchange and to incorporate scientific and local
knowledge into decision-making?
3. Values• How to assign value to ecosystem states, e.g. is an system which
supports Atlantic cod inherently better than one that supports northern shrimp?

Example case study: Atlantic cod in NewfoundlandExample case study: Atlantic cod in Newfoundland
The collapse of cod has been severe social disruption in Newfoundland. In addition to the social displacements, there have been changes in the ways that coastal communities use the marine ecosystems:
• have expanded into previously un-fished species, • have expanded into new locations,• are using previous fishing grounds for species other than
cod.
Result is potential for significant negative impacts on the marine ecosystem, and on the recovery of cod.
Working Group Approach
• Develop a review/appraisal paper on the topic “What are the impacts of marine ecosystem changes on coastal communities?”. Case studies might include: Peru and changes induced by El Nino oscillations; NW Atlantic groundfish collapses
• Explore “significant issues”, starting with “Scale” (a MS has been submitted)
• Develop models coupling marine ecosystem changes with the socio-economic system.
• Develop active links with other relevant programs, e.g. GECaFS, by exploring these issues for the marine ecosystems of Peru, Chile and Ecuador; or possibly the Caribbean?
