Implications, adaptations & policies for food security and livelihoods

Based on…..

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

Goal to use fish for food security

• Provide 35 kg of fish per person per year

Vanuatu

• 20 kg of fish per person per year

Where does most fish come from?

• Coastal fisheries / coral reefs, mangroves and sea grasses

How Much is available ?

Smol Problem!

 Sustainable catches from most reefs are unknown

Solution: use median estimate of

3 tonnes per km 2 per year

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

500+ terrestrial adaptation strategies for various climate impacts

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 communitybased actions supported by partners
