  1. WORKSHOP ON INTEGRATING CLIMATE CHANGE AND DISASTER RISK REDUCTION INTO VOCATIONAL EDUCATION AND TRAININGIMPACT OF CLIMATE CHANGE ON FISHERIES SECTOR AND OPTIONS FOR ADAPTATION AND MITIGATION IN VANUATU Jason Raubani Vanuatu Fisheries Department

  2. IMPACT OF CLIMATE CHANGE ON FISHERIES SECTOR IN VANUATU • Coral and habitat destruction • Cyclone • Increase SST • Sea level rise • Run-offs • Coral bleaching and other climate change related activities • Acidification (acidity affect formation of calcium shells and bones of marine resources) • Movement and displacement of pelagic species i.e. tuna • High rainfall • Ciguatera (warmer waters increase risk)

  3. Tuna Fisheries

  4. Projected effects on skipjack tuna • Catch in 2009 • 1.75 million tonnes • ~ USD 2.2 billion 2000 • Effects due to: • Increases in sea surface temperature in eastern Pacific • Shift of prime feeding areas to the east (convergence between the Warm Pool and Pacific Equatorial Divergence Province) 2050 Source: Lehodey et al. (2011)

  5. Effects on skipjack tuna catches Changes relative to 1980-1999 average catch

  6. Coral Reef and Coastal Fisheries

  7. Projected effects on coral reef fish Today 2035 (-2 to -5%) • Effects due to: • Increased sea surface temperature and more frequent bleaching • Ocean acidification • Greater runoff of nutrients due to higher rainfall • Cyclones of greater intensity 2050 (-20%) 2100 (-20 to -50%)

  8. Freshwater fishery

  9. Effects on freshwater fish catch • Effects due to: • Increased air temperature • Higher flow rates • Increased freshwater habitat

  10. Aquaculture

  11. Coastal aquaculture commodities • Pearls • Shrimp • Seaweed • Marine ornamentals • Effects due to: • Increased sea surface temperature • Ocean acidification • Greater runoff of nutrients • Sea-level rise • More-intense cyclones

  12. Pond aquaculture commodities • Tilapia • Effects due to: • Increased surface air temperature (faster growth rates in ponds) • Higher rainfall (more places to build ponds)

  13. Summary of changes in production

  14. ADAPTATION AND MITIGATION OF CLIMATE CHANGE IN FISHERIES • Rehabilitation and restocking program of shell fish • Increase access to tuna for subsistence fishers with low-cost, inshore Fish Aggregating Devices (FADs) • Promote alternative fisheries or employment for fishers • Store and distribute tuna and bycatch from industrial fleets to urban areas • Develop pond aquaculture • Promote storage facilities and Post harvest techniques to minimize wastage of resources • Awareness programs
