Fishery management Institutions and the Challenge of Change Robin Allen Inter-American Tropical Tuna Commission

Ministerial declaration, Conference on Fisheries Governance Recognizing that RFMOs today face new challenges and responsibilities, and while the governance of some RFMOs has been improved by incorporating the principles and provisions of newly developed international instruments and tools, including, inter alia, those related to ecosystem considerations in fisheries management, other RFMOs remain to be so improved and, to that end, there is a need for political will to further strengthen and modernize RFMOs to ensure that such challenges and responsibilities are effectively addressed;

UNFSA and FAO CCRF If a natural phenomenon has a significant adverse impact on the status of living aquatic resources, States should adopt conservation and management measures on an emergency basis to ensure that fishing activity does not exacerbate such adverse impact. States should also adopt such measures on an emergency basis where fishing activity presents a serious threat to the sustainability of such resources. Measures taken on an emergency basis should be temporary and should be based on the best scientific evidence available.

Best estimate for low scenario (B1) is 1.8°C (likely range is 1.1°C to 2.9°C), and for high scenario (A1FI) is 4.0°C (likely range is 2.4°C to 6.4°C). Fig SPM-5 IPCC Climate Change 2007: The Physical Science Basis

Norway FAO COFI intervention Climate change might be the factor that will affect the marine ecosystem most. The IPCC report, released a few weeks ago, points to a number of disturbing trends. The Panel predicts that global temperatures will continue to rise, at an average rate of some 0.2 centigrade per decade. Among the consequences are sea level rise, declining extent of sea ice in the Polar Regions, and major changes to ecosystems. Confronting climate change, therefore, is the biggest challenge facing mankind today … The consequences of climate change for fisheries can be dramatic – in this century. It may well be that climate change is the biggest challenge to fisheries globally over the next decades. Doing nothing is therefore not an option … the “sit back and wait” approach is likely to be a very costly one. We will therefore propose … that the FAO undertake a major scoping study to identify the major issues regarding climate changes and fisheries. As a second step initiate a global think-tank on how the fishing industry globally can adapt to climate change. And third, FAO has an important mission in informing fishers and policymakers about the likely consequences of climate change for this sector.
