Presentation Transcript

  1. Case-Studies: climate Change and Fisheries 16 April 2012 FW 481 Abigail Lynch

  2. Outline • Approach/Objectives (5 min.) • Context for discussion (5 min.) • UK case-study(25 min.) • Group case-studies (20 min.) • Discuss group case-studies as a full class (15 min.) • Prep for next class (1 min.) • Survey (10 min.) Red = “active”

  3. Problem-Based Learning • Identify: • What you already know. • What you need to know. • Decide: • How to access new information that may lead to resolution of the problem. • Recommend: • Potential resolutions for the problem.

  4. Objectives • Identify the management challenges for these fisheries case-studies. • Decide what needs to be known to address these management challenges. • Discuss potential solutions to make these fisheries sustainable in the face of climate change.

  5. Context • Science of anthropogenic climate change • Established that climate change is occurring and is human-induced. • Impacts of climate change on fisheries • Discussed the socio-ecological, economic, and governance challenges climate change adds to fisheries. • Realized that there are no easy solutions. • Case-studies of climate change and fisheries • Apply previous class discussions to work towards recommendations for improved management. GLOBAL ONE SECTOR SPECIFIC EXAMPLES

  6. UK Case-Study

  7. Identify the management challenges UK Fishing History • Overfishing • Overcapacity • Bycatch

  8. Identify the management challenges General climate change projections • Increased average sea temperature • 1.5-4oC • Increased sea level • 0.18-0.59m • Ocean acidification • pH  0.3 • Storm intensity/ocean circulation • Long-term impacts uncertain…ice age?

  9. Identify the management challenges Projections for fish • Finfish distribution shifts • Cold-water: cod; herring • Warmer-water: sole, red mullet, seabass • Shellfish • Oysters, mussels, scallops • Ocean acidification http://www.thefishsociety.co.uk

  10. Decide needed information Adaptation and UK Fisheries • If you were the manager, what information would you want to know? • Abundance and distribution of fish? • Surplus production? • Minimize what uncertainties? • Market drivers? • Enforcement funding? • Capacity of the fleet? • Alternative livelihood options? • How would you get this information?

  11. Discuss potential solutions Moving forward • How can UK fisheries be sustainable in the face of climate change? • Incentivize adaptive approaches? • Re-evaluate subsidies? • Spatial planning?

  12. Group Case-studies http://www.youtube.com/watch?v=FhsC8xMFpDI

  13. Korea

  14. Discuss potential solutions Moving forward

  15. Chinese Taipei

  16. Discuss potential solutions Moving forward

  17. Class Discussion • Commonalities across the case-studies? • Barriers? • Uncertainties? • Solutions? • Unique characteristics of case-studies? • What inhibits universal management approaches?

  18. Objectives • Identify the management challenges for these fisheries case-studies. • Decide what needs to be known to address these management challenges. • Discuss potential solutions to make these fisheries sustainable in the face of climate change.

  19. Next Class • Climate change module evaluation (15 min.) • SIRS evaluation (15 min.) • Group Presentation (40 min.) • Joe, Chris, Cristina, Marielle • GMO salmon • 2 readings; directed post Any allergies?

  20. Survey Use your pseudonym Be honest – we appreciate your suggestions  Thank you!
