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.

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.

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.

UK Fishing History

Overfishing

Overcapacity

Bycatch

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?

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

Identify the management challenges

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

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

Class Discussion

Commonalities across the case-studies? Barriers? Uncertainties? Solutions?

Unique characteristics of case-studies? What inhibits universal

management approaches?

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.
