First global assessment

First Global Assessment

  • 171 countries/territories

  • All waters within EEZs

  • >100 data layers


Some key messages results

Some key messages/results

  • Index provides a portfolio perspective

  • Sustainability fundamental to, and operationalized in, the Index

  • Human benefits central to Index

  • Different perspectives incorporated


Portfolio perspective many ways to get a score

AO = Artisanal Opportunity

FIS = Fisheries

MAR = Mariculture

NP = Natural Products

CS = Carbon Storage

CP = Coastal Protection

TR = Tourism & Recreation

LIV = Livelihoods

ECO = Economies

ICO = Iconid Species

LSP = Lasting Special Places

HAB = Habitats

SPP = Species

CW = Clean Waters

Accounting for different perspectives weighting goals by value sets

Accounting for different perspectives: weighting goals by value sets

  • People care about different aspects of the ocean

  • These differences are really important to understand and capture if management is to be effective


Assessing the health of the world s ocean

All goals are presumed equally important

Extractive goals are presumed more important
