Implications, adaptations & policies for food security and livelihoods Solomon Islands Government
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 • Maintain traditional fish consumption where it is >35 kg • Solomon Islands • 33 kg of fish per person per year Plans to use fish for food security

The problem! • Sustainable catches from most reefs are unknown Solution: use median estimate of 3 tonnes per km2per year
Annual coastal fish production (mt) • Population in 2010 was 550,000 • ~ 46 kg of fish per person per year
Factors affecting availability of fish • Population growth Source: SPC Statistics for Development Programme
Effects of population growth on availability of fish per person 2035 2050 2100
Effects of climate change Today 2035(-2 to -5%) 2050 (-20%) 2100 (-20 to -50%)
Additional effects of climate change Additional effects of climate change Effects of population growth
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

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 • Restrict export of demersal fish to retain them for national food security • Increase access to tuna for the food security by reducing national allocations to industrial fleets • Capitalise on opportunities for freshwater pond aquaculture • Limit farming of Nile tilapia to catchments where tilapia species are already established, or there is a shortage of fish
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 • 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
