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
fisheries 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 communitybased actions supported by partners
