  • Rising to Depletion ? Towards a dialogue on the state of national marine fisheries A PROFISH Preliminary Report presented to the World Bank on 26 May 2009
  • Slide 2
  • Outline 1.Introduction 2.The approach 3.The data 4.Selected results 5.Discussion 6.Conclusions
  • Slide 3
  • 1. Introduction The study backdrop 90% of stocks are under national jurisdiction and the large majority is under excessive pressure Countries are responsible and committed to restore stocks by 2015 (WSSD POI) but progress is very slow At global level, information on stocks is often scarce, fragmented, too slowly updated and often outdated There is therefore no regularly updated and easily accessible indicator of fishery development level at national, regional or global level
  • Slide 4
  • 1. Introduction The study outcome An approach providing a simple, generally available and effective entry point into an interactive fishery reform process The approach is scalable, at sub-sectoral, sectoral, national, regional or global levels It may encourage countries to: Build on their existing efforts, making better use of available statistics Improve the quality of their statistics formalizing their use as indicators and Publicly account for the health of their fishery resources

  • 5. Conclusion The title 0 Depletion Rising to As the aggregated level of saturation of the sector is reached, the risk of depletion increases
  • Slide 35
  • 5. Conclusion The bottom line Countries are responsible for meeting their WSSD commitments A robust country-level indicator on the state of the sector would help counties assess their progress and inform society Existing statistics offer a possibility to be fully examined. They are underused and could be improved Countries can improve on this first proposal through their own efforts. The Bank could help. Country reporting to FAO would also be improved
  • Slide 36
  • 5.Conclusions What next regarding the study? Continue peer review Complete the analyses by resource types Case studies (West Africa)
