Implications, adaptations & policies for food security and livelihoods
Where are we in the programme? Projected changes to atmospheric and oceanic conditions Ecosystems supporting fish Fish stocks/aquaculture species Implications for economic development, food security and livelihoods Adaptations and policies to reduce threats and capitalise on opportunities
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 • Win-win adaptations • Supporting policies
Provide 35 kg of fish per person per year • Vanuatu • 20 kg of fish per person per year Goal to use fish for food security
Coastal fisheries / coral reefs, mangroves and sea grasses • How Much is available ? Where does most fish come from? Photos: Eric Clua, Gary Bell, Christophe Launay
Smol Problem! • Sustainable catches from most reefs are unknown Solution: use median estimate of 3 tonnes per km2per year
Annual coastal fish production (mt) 3 tonnes x • Population in 2010 was 252,000 • ~ 15 kg of fish per person per year
Provide 35 kg of fish per person per year • Vanuatu • 20 kg of fish per person per year (15 from reefs 5 from tuna) UHH OHH!

Adaptations • Must minimise and then fill the gap
Adaptation decision framework Addresses climate change Long-term Loss Long-term Gain Near-term Loss Addresses present drivers Win-Lose Near-term Gain After Grafton (2010)
Win-win adaptations Manage and restore vegetation cover in catchments L-L L-W W-L W-W Improves resilience of coral reef, mangrove and seagrass habitats
Win-win adaptations Sustain production of fish stocks L-L L-W Maintaining spawning adults will help ensure replenishment and build resilience of key species W-L W-W
How best to fill the gap to provide 35kg/person? Coastal fisheries Freshwater fisheries Pond aquaculture Tuna & bycatch
Win-win adaptations Store and distribute tuna and bycatch from industrial fleets to urban areas L-L L-W W-L W-W
Win-win adaptations Increase access to tuna with anchored inshore Fish Aggregating Devices (FADs) L-L L-W W-L W-W

Other adaptations Provide for landward migration of coastal fish habitats L-L L-W W-L W-W
Other adaptations Reduce and diversify catches of demersal fish L-L L-W W-L W-W Greater focus on herbivorous fish
Other adaptations Allow for expansion of freshwater fish habitats L-L L-W W-L W-W
Suggested supporting policies • Strengthen governance of agriculture, forestry and mining practices to prevent soil loss and pollution, to safeguard fish habitats and water quality • Minimise barriers to migration of coastal and freshwater habitats • Promote mangrove replanting programmes • Apply ‘primary fisheries management’ to coastal and freshwater stocks to maintain their potential for replenishment
Suggested supporting policies • Apply ‘primary fisheries management’ to coastal and freshwater stocks to maintain their potential for replenishment • gear restrictions • spatial closures • size limits • closed seasons
Suggested supporting policies • Increase access to tuna for the food security • Capitalise on opportunities for freshwater pond aquaculture
Key investments • Surveys of best sites for installing inshore FADs • Programmes to install and maintain FADs • Identify prime locations for peri-urban and rural pond aquaculture • Hatcheries and networks to deliver juveniles • Evaluate merits of micro-credit schemes to develop fisheries around FADs; expand pond aquaculture; and scale-up post-harvest processing

Conclusions • Win-win adaptations are available to reduce risks and capitalise on opportunities • Much ADAPTATION can be done cheaply now • Supporting policies and investments are needed • Integrate adaptations and policies and investments into national strategies and action plans for climate change, including community-based actions supported by partners
