The health of the world’s oceans has been assessed on a country-by-country basis for the first time. Overall, they got the passing grade of 60 out of 100. Canada’s received 70. The international team behind the list included University of British Columbia fisheries experts. From UBC:
The team undertook the first global quantitative assessment of ocean health and created the Ocean Health Index (http://oceanhealthindex.org), published today in the journal Nature. To calculate the overall score, ecological, social, economic, and political conditions were evaluated for every coastal nation in the world.
The scores for individual countries ranged widely: from Sierra Leone, with a failing scores of 36, to Jarvis Island, an uninhabited, relatively pristine island in the South Pacific, with the highest scores of 86.
Canada is among the top performers with a score of 70 while the U.S. received 63 and the U.K. received 62.
Researchers from UBC’s Fisheries Centre were responsible for measuring the amount of seafood that is sustainably generated by fisheries and marine aquaculture for human consumption. “Fisheries are one of the most important ‘services’ the ocean offers us, and one of the areas where we’re making the biggest impact on the sustainability and ecosystems of the ocean,” says Kristin Kleisner, a postdoctoral fellow with the Sea Around Us Project and a co-author of the study.
“The Ocean Health Index offers an excellent framework to assess if things are getting better or worse in response to our actions,” says Daniel Pauly, principal investigator with the Sea Around Us project and the study’s co-author. “Although Canada did comparatively well, it has so far set aside only one per cent of its waters as marine protected areas. We would like to see progress in this area and others.”
