Global Fisheries Have Declined Due to Ocean Warming, 'Groundbreaking' Study Finds
More than 56 million people work in the global fishing industry or depend on fish for their main source of food, but that livelihood is already being threatened by climate change, a groundbreaking University of Rutgers led study found.
The study, published in Science Friday, looked at the impact of increased ocean temperatures on sustainable catches around the world over an 80 year period and found they had declined on average by 4.1 percent.
"We were stunned to find that fisheries around the world have already responded to ocean warming," study co-author and Rutgers' Department of Ecology, Evolution, and Natural Resources associate professor Malin Pinsky told Rutgers Today."These aren't hypothetical changes sometime in the future."
While 4.1 percent might not sound like a large amount, lead author Chris Free explained to The New York Times that it was still a big loss.
"That 4 percent decline sounds small, but it's 1.4 million metric tons of fish from 1930 to 2010," Free said, referring to the 80-year-period covered by the study.
Further, some regions of the world saw a steeper decline. In both the northeast Atlantic and the Sea of Japan, sustainable catches declined by 34 and 35 percent respectively over the study period.
Scientists not involved in the study lauded it as an important contribution to the knowledge of how climate change impacts marine life.
"This is going to be one of those groundbreaking studies that gets cited over and over again," University of Washington School of Aquatic and Fishery Sciences Associate Professor Trevor Branch told The New York Times "Most of what I've seen before in terms of climate-change impacts have been speculative, in terms of, 'We think this is what's going to happen in the future.' This one's different."
The researchers looked at 235 populations of 124 species in 38 regions, according to Rutgers Today.
Here are some of their key findings by region, as reported by The New York Times:
- About a quarter of the regions studied saw fish populations increase; black sea bass catches increased by six percent off the U.S. Atlantic coast.
- About of a quarter of the regions studied saw no changes, including the northwest Atlantic.
- Half of the regions studied saw fish populations decline.
- Fish in colder areas responded better to warming generally than fish in already warm water.
However, the scientists warned that populations that had benefited from warming so far could still be harmed by it in the future.
"Fish populations can only tolerate so much warming, though," senior author and Rutgers' Department of Marine and Coastal Sciences associate professor Olaf Jensen told Rutgers Today. "Many of the species that have benefited from warming so far are likely to start declining as temperatures continue to rise."
The scientists said that ultimately the solution was to curb climate change, but also recommended actions to mitigate its impacts on global fisheries.
"We recommend that fisheries managers eliminate overfishing, rebuild fisheries and account for climate change in fisheries management decisions," Free, who started the research as a doctoral student at Rutgers and is now a post-doctoral scientist at the University of California, Santa Barbara, told Rutgers Today. "Policymakers can prepare for regional disparities in fish catches by establishing trade agreements and partnerships to share seafood between winning and losing regions."

World Environment Day: A Time to Consider the Planet We’ll Return To, and Decide How to Care For It Going Forward
It's a different kind of World Environment Day this year. In prior years, it might have been enough to plant a tree, spend some extra time in the garden, or teach kids the importance of recycling. This year we have heavier tasks at hand. It's been months since we've been able to spend sufficient time outside, and as we lustfully watch the beauty of a new spring through our kitchen's glass windows, we have to decide how we'll interact with the natural world on our release, and how we can prevent, or be equipped to handle, future threats against our wellbeing.

The SARS-CoV-2 virus is novel, but pandemic threats to indigenous peoples are anything but new. Diseases like measles, smallpox and the Spanish flu have decimated Native American communities ever since the arrival of the first European colonizers.

History Reverberates on Native Lands<p>Native communities in North America have been disrupted and displaced for centuries. Many face long-standing food and water <a href="http://www.nativepartnership.org/site/DocServer/2017-PWNA-NPRA-Food-Insecurity-Project-Grow.pdf?docID=7106" target="_blank">inequities</a> that are further complicated by this pandemic.</p><p>On the Navajo reservation, which covers more than 27,000 square miles in Arizona, Utah and New Mexico, 76% of households already <a href="https://www.researchgate.net/publication/235390130_High_levels_of_household_food_insecurity_on_the_Navajo_Nation" target="_blank">have trouble affording enough healthy food</a>, and the nearest grocery store is often hours away. COVID-related restrictions have further curtailed access to food supplies.</p><p>Clean water for basic sanitary measures like hand-washing is also scarce. Native Americans are <a href="http://uswateralliance.org/sites/uswateralliance.org/files/Closing%20the%20Water%20Access%20Gap%20in%20the%20United%20States_DIGITAL.pdf" target="_blank">19 times more likely</a> to lack indoor plumbing than whites in the U.S. Nearly one-third of Navajo households <a href="https://www.nbcnews.com/news/us-news/coronavirus-hits-indian-country-hard-exposing-infrastructure-disparities-n1186976" target="_blank">lack access to running water</a>.</p><p>Many <a href="https://www.cdc.gov/mmwr/volumes/69/wr/mm6915e3.htm" target="_blank">health issues</a> that can increase COVID-19 mortality rates occur at high levels among Native Americans. These <a href="http://www.ncai.org/news/articles/2020/03/18/the-national-congress-of-american-indians-calls-for-more-attention-to-covid-19-impacts-to-indian-country" target="_blank">underlying</a> and <a href="https://doi.org/10.1016/S0140-6736(20)30893-X" target="_blank">preexisting</a> conditions – things like hypertension, diabetes, obesity and cardiovascular disease – are <a href="https://www.cdc.gov/mmwr/volumes/69/wr/mm6913e2.htm" target="_blank">linked to diet</a> and stem from <a href="https://www.oupress.com/books/15107980/indigenous-food-sovereignty-in-the-united-sta" target="_blank">disruption and replacement</a> of Indigenous food systems.</p>
High Exposure Rates<p>These factors have clear health impacts. On the Navajo reservation, for instance, through May 27, 2020, <a href="https://www.navajo-nsn.gov/News%20Releases/OPVP/2020/May/FOR%20IMMEDIATE%20RELEASE%20-%201620%20recoveries_102%20new%20cases%20of%20COVID-19_and%20one%20more%20death%20reported.pdf" target="_blank">4,944 people</a> out of a population of 173,000 had tested positive for COVID-19, and 159 had died.</p><p>This infection rate per capita exceeds those in hot spots such as <a href="https://www.forbes.com/sites/alexandrasternlicht/2020/05/19/navajo-nation-has-most-coronavirus-infections-per-capita-in-us-beating-new-york-new-jersey/#11a4fac08b10" target="_blank">New York and New Jersey</a>. Importantly, however, it may also reflect a much <a href="https://www.sltrib.com/news/2020/04/19/navajo-nation-has-higher/" target="_blank">more proactive approach to testing</a> on reservations than in many other jurisdictions.</p><p>The fact that elderly people are especially vulnerable to COVID-19 could worsen the pandemic's effects in Indian Country. Elders are the <a href="https://ais.washington.edu/research/publications/spirits-our-whaling-ancestors" target="_blank">keepers of traditional knowledge, tribal languages and culture</a> – legacies whose loss already threatens the persistence of indigenous communities.</p><p>Elders also play key roles in preserving traditional plant and medicine knowledge. In the absence of COVID-19 interventions from Western medicine, many elders have been called on to perform healing practices, which increases their exposure risk.</p>
Little Help From Federal and State Governments<p>Many tribal members rely on the federal government's <a href="https://www.ihs.gov/" target="_blank">Indian Health Service</a> for health care. But <a href="https://theconversation.com/tribal-leaders-face-great-need-and-dont-have-enough-resources-to-respond-to-the-coronavirus-pandemic-134372" target="_blank">lack of capacity</a> at the agency has hampered its response.

Environmental Injustices on Native Land<p>Energy development and resource extraction have had <a href="https://www.haymarketbooks.org/books/898-all-our-relations" target="_blank">disproportionate impacts</a> on tribes for many years. Today, many Native American leaders worry that ongoing energy production – <a href="https://www.ncsl.org/research/labor-and-employment/covid-19-essential-workers-in-the-states.aspx" target="_blank">an "essential" activity under federal guidelines</a> will bring outsiders into close contact with reservation communities, worsening COVID risks.</p><p>The owners of the Keystone XL oil pipeline have announced that they intend to continue construction, which will bring an influx of workers along the proposed route through Montana, South Dakota and Nebraska. The Rosebud Sioux Tribe in South Dakota and Fort Belknap Indian community in Montana have filed for a <a href="https://www.narf.org/keystone-xl/" target="_blank">temporary restraining order</a>, and a key permit for the pipeline was <a href="https://www.democracynow.org/2020/4/16/headlines/us_judge_revokes_crucial_permit_for_keystone_xl_pipeline" target="_blank">revoked in April 2020</a>, but work continues at the U.S.-Canada border.</p><p>Construction is accelerating on the <a href="https://www.azcentral.com/story/news/politics/border-issues/2020/03/17/border-patrol-waives-laws-border-wall-construction-southern-arizona/5063618002/" target="_blank">southern border wall</a>, which bisects the <a href="http://www.tonation-nsn.gov/" target="_blank">Tohono O'odham reservation</a> in Arizona and Mexico. The Trump administration has <a href="https://www.thenation.com/article/politics/border-coronavirus-military-immigration/" target="_blank">increased patrols at the border</a>, despite the tribe's concern that the patrols' presence is <a href="https://www.usatoday.com/story/news/nation/2020/04/06/coronavirus-cbp-160-cases-covid-19-officers-agents/2958736001/" target="_blank">spreading coronavirus</a> on the reservation.</p><p>And in Bristol Bay, Alaska, a salmon fishing season that brings in thousands of temporary workers is <a href="https://indiancountrytoday.com/news/it-s-hard-when-you-love-something-xlS49l2N20KZjqumwfzZfQ" target="_blank">set to open in June</a> because the federal government has also deemed commercial fishing "<a href="https://www.cisa.gov/sites/default/files/publications/CISA-Guidance-on-Essential-Critical-Infrastructure-Workers-1-20-508c.pdf" target="_blank">essential critical infrastructure</a>."

The ocean is our lifeline - we rely on it for the food we eat, the air we breathe, as well as for millions for jobs worldwide.
As we continue to grapple with the issues of overfishing, plastic pollution, and climate change, there exists an opportunity to address these existential threats with new innovations, many of which unidentified or insufficiently supported.
