Updated 2014 Ocean Health Index Scores

Each year, the Ocean Health Index incorporates improvements in methods or data. Those improvements change scores and rankings of countries and their territories. When updates are made, all earlier scores are recalculated using the new methods and information so that any differences in scores between years is due to changes in the conditions evaluated, not to changes in methods.

This permits year-to-year comparison between results. Many of the new scores may differ from scores originally posted on the Web site or shown in previously published scientific reports. Therefore, only the scores most recently posted at www.oceanhealthindex.org should be compared, as scores posted or published in earlier years may have changed.

Key Points

  • The overall score, 67 is unchanged from 2013, though improved by one point since 2012.
  • A 4 point increase from in the Livelihoods & Economies score from its value in 2012, as well as the 7 point increase in its Economies subgoal score, may reflect the beginnings of marine sector economic recovery following the global recession that began in 2008.      
  • A 3 or 4 point increase in the Lasting Special Places subgoal score since 2012 probably reflects small, but broad increase in the number of no-take marine protected areas that have been created in the coastal zone.     
Continental-scale Scores
  • Highest scoring was North America (71) followed by Europe and Oceania (both 70).  South America scored 63, followed by Africa (63) and Asia (62).  The highest scoring subregions were Australia and New Zealand (77) and Northern Europe (73). 
  •  The lowest scoring subregion was middle Africa, comprising Republique du Congo, Sao Tome and Principe, Equatorial Guinea, Cameroon, Gabon, Democratic Republic of the Congo and Angola, which scored 53, followed by West Africa, the Caribbean, South Asia and West Asia (all 60). 
Regional Scores
  • Regional scores ranged from 44 (Haiti and St. Vincent and the Grenadines) to 95 (Howland Island and Baker Island).  Only three regions scored above 90.
  • Regions scoring higher than 80 were: Howland Island and Baker Island (95), Prince Edward Islands (93), Heard and McDonald Islands (93),   Macquarie Island (87), Kerguelen Islands (87), Crozet Islands (86), Jarvis Island (86), Malta (84), Greenland (83), Johnston Atoll (82), Palmyra Atoll (81), Norfolk Island (80), Estonia (80) and Northern Saint-Martin (80). 
  • Among the 14 countries or territories scoring 80 or higher, all but Estonia (population 1.325 million) are islands, mostly small, remote and unpopulated, but also including densely-populated Malta (84, population about 423,000); Greenland, the world’s largest island (83, population about 56,000) and Northern Saint Martin Island (population about 36,000). 
  • Twenty (20) countries scored 50 or below: Senegal (50), Barbados (50), North Korea (49), Pakistan (49), Dominica (49), Grenada (49), Guinea (49), Somalia (48), Guinea Bissau (48), Angola (48), East Timor (48), Eritrea (47), Libya (47), Liberia (47), Sierra Leone (45), Nicaragua (45), Ivory Coast (45), Democratic Republic of the Congo (45), Haiti (44) and Saint Vincent and the Grenadines (44).
