Focus 4

Feedback from Marine Ecosystem Changes

The overall objective of Focus 4 was to co-operate with other ocean, atmosphere, terrestrial and social global change research programmes to estimate feedback from changes in marine ecosystem structure to the global earth system with emphasis on the following three activities:

  • Selecting appropriate topics for interaction, for example, carbon fluxes, in consultation with other programmes
  • Predicting scenarios of altered marine ecosystem structure and their impact on important stocks, and potential feedback to the global system
  • Drawing on the results of other international programmes involved in modelling climate change and its impacts

Focus 4 therefore operated in a slightly different manner from Focus 1, 2 and 3. Due to the diversity and breadth of topics, Focus 4 was implemented through groups of experts selected to work on particular topics, rather than through a fixed group that worked on several topics simultaneously (as for Focus 1, 2 and 3).

This page will detail Focus 4 activities as well as those relevant to this Foci. GECaFS (Global Environmental Change and Food Systems) is a crosscutting activity of the IGBP, the WCRP and IHDP with participation by GLOBEC. The activity is guided by the need to understand and estimate the impacts of global change on the availability of, and access to food, and the environmental and social consequences of increasing production. GLOBEC considered GECaFS as a Focus 4 activity.

The general objective of IOC/SCOR WG 119 Quantitative Ecosystem Indicators for Fisheries Management is to develop theory to evaluate changes in marine ecosystems (both states and processes) from environmental, ecological and fisheries perspectives. GLOBEC saw the work of WG119 as highly relevant to its objectives, particularly with respect to Focus 4, and followed its development carefully.

Coping with global change in marine social-ecological systems

A symposium on "Coping with global change in marine social-ecological systems" was held 8-11 July 2007 at FAO in Rome, Italy. The central goals of the symposium were to share experiences across disciplines and to identify steps and common elements and approaches that would promote resilience of marine social-ecological systems in the face of global changes.
