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. Effects Impacts Solutions GLOBAL ONE SECTOR SPECIFIC EXAMPLES

6 UK CASE-STUDY

7 UK Fishing History Overfishing Overcapacity Bycatch Identify the management challenges

8 General climate change projections Increased average sea temperature o C Increased sea level m Ocean acidification pH 0.3 Storm intensity/ocean circulation Long-term impacts uncertain…ice age? Identify the management challenges

9 Projections for fish Finfish distribution shifts Cold-water: cod; herring Warmer-water: sole, red mullet, seabass Shellfish Oysters, mussels, scallops Ocean acidification Identify the management challenges

10 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? Decide needed information

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

12 GROUP CASE-STUDIES

13 KOREA

14 Moving forward Discuss potential solutions

15 CHINESE TAIPEI

16 Moving forward Discuss potential solutions

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?
