Improving the basis for MPA planning INCOFISH WP5

WP5 – Improving the basis for MPA planning Improving the basis for MPA planning with emphasis on sizing and placement of MPAs, and reconciling fishery and biodiversity objectives. Objectives D5.1 Review of the similarities and differences of planning, stakeholder involvement and effectiveness of selected MPAs. D5.2 Analysis of size and placement of selected MPAs using spatial ecosystem models provided by WP4. D5.3 Conceptual model for MPA planning in offshore continental shelf waters. D5.4 WP5 report. D5.5 Five publications.

WP5 – Improving the basis for MPA planning D 5.1 Review of MPA Effectiveness Case Study Regions: Northern Gulf of California, Campeche Bank - Gulf of Mexico, East China Sea, North Sea

WP5 – Improving the basis for MPA planning D 5.1 Review of MPA Effectiveness MPAs show great similarities in objectives and application across a diverse range of marine ecosystems and political settings. Limited and sporadic monitoring and assessment critically compromises the ability to determine MPA effects. There is only limited evidence for biodiversity conservation benefits and no evidence for improved fishery yields from the case studies. Socio-political considerations are as important to MPA success as biophysical considerations.
