  1. Implications for food security and livelihoods

  2. Based on…..

  3. Where are we in the programme? Projected changes to atmospheric and oceanic conditions Ecosystems supporting fish Fish stocks/aquaculture species Implications for food security and livelihoods Adaptations and policies to reduce threats and capitalise on opportunities

  4. Outline • Factors affecting availability of fish for food • Reef area, population growth, climate change • Implications for food security • Relative importance of population growth and climate change

  5. Provide 35 kg of fish per person per year • Maintain traditional fish consumption where it is >35 kg • Samoa • >60 kg of fish per person per year Plans to use fish for food security

  6. Coastal fisheries / coral reefs, mangroves and sea grasses Where does most fish come from? Photos: Eric Clua, Gary Bell, Christophe Launay

  7. The problem! • Sustainable catches from most reefs are unknown Solution: use median estimate of 3 tonnes per km2per year

  8. Reef around Samoa

  9. Coral reef area in Samoa *Includes much rough ground with no living coral ** Includes reef fish and invertebrates, not nearshore pelagic fish

  10. Factors affecting availability of fish • Population growth Source: SPC Statistics for Development Programme

  11. Availability of reef fish per person (kg) 50 Samoa Effects of population growth on availability of fish per person 40 35 kg 30 3 20 5 6 30 10 29 25 10 0 2035 2050 2100 Year

  12. Effects of climate change Today 2035(-2 to -5%) 2050 (-20%) 2100 (-20 to -50%)

  13. Availability of reef fish per capita (kg) 50 Samoa Additional effects of climate change 40 35 kg 30 10 13 5 5 6 6 6 6 10 10 20 29 30 29 25 25 10 20 25 25 25 22 25 22 0 2035 2050 2100 Year Additional effects of climate change Effects of population growth
