Food security and aquaculture
• Food security is the key element to reduce poverty and hunger
• Aquaculture has been contributing significantly to food security (Kent, 1995)

Projected aquaculture and fish consumption
Aquaculture Food fish consumption
“ensuring that all people at all times have both physical and economic access to
the basic food that they need” – FAO, 1983
Climate change
• Consequences of climate change (IPCC and FAO, 2009)
– Global warming
– Sea level rise
– Changes of ocean productivity
– Water shortage
– More frequent extreme climate events

Climate change
• Impact of aquaculture on climate change
– No greenhouse gas (GHG) emission from aquatic animals
– Two majors contributions to GHG emissions in salmon production* (Wright, 2011)
