#oceanoptimism — Public Fediverse posts

Hence, we need to balance our narrative about the future of the ocean.
A few years ago, we published a paper prioritizing topics for a positive action from media, scientists and society.

In Europe, this is translated into the Nature Restoration Regulation,
The target is recover 20% of the sea by 2030, and all ecosystems by 2050.
See you next week, with more hope for the #ocean

At the same time, we have the UN Decade on Ecosystems Restoration 2021-2030,
This is to prevent, halt and reverse loss of nature and #biodiversity #GenerationRestoration

There are plenty of actions to study the ocean, including mapping the #seabed, #eDNA expeditions, satellite observations, #bluecarbon studies, etc.

All the examples we have seen up to now are supported by good science.
We have the UN Decade of the Oceans 2021-2030 "The science we need for the ocean we want" to do this good science

More hope for #ocean
The Marine Protection Atlas measures progress toward protecting 30% of the #ocean in fully and highly protected areas by 2030.
As of today, 9.6% of the ocean is protected and 3.2% is highly protected.

These authors consider that rebuilding marine life by 2050 is an achievable challenge for science and society
This requires action to reduce #pressures and #climatechange, safeguarding places of remaining abundance, and recovering depleted populations and habitats
Hope for sea!

Also, Duarte et al show the recovery trends of marine populations,
For example, assessed fish stocks and marine mammals, with clear recovery
They show many examples of hope, if management is adequately undertaken
#GES4SEAS #MOOC #oceanoptimism #MarineEcology #Research

These authors show the global growth of restoration interventions,
These have been done in #MPAs Marine Protected Areas, #coral and oyster reefs, #saltmarshes, #mangroves, kelps and #seagrasses
There is a clear increase of recovery in recent years
#GES4SEAS #MOOC #oceanoptimism #MarineEcology #Research

We follow with our previous comment on rebuilding sea life
Duarte et al (in Nature, in 2020) think that sustainably use of the #ocean requires this rebuilding
Recovery of #habitats and ecosystems following past #conservation interventions

After some research, from 1869 to 2016, one third of European #seagrass area was lost due to disease, deteriorated water quality, and coastal development
The highest decline was the 1970s and 1980s

At global level, we have good news!
In January, the Biodiversity Beyond National Jurisdiction (BBNJ) Agreement entered into force. This legally binding UN High Seas Treaty covers the ocean zones that lie beyond national waters
What does this mean? #GES4SEAS #MOOC #oceanoptimism #MarineEcology #Research

We follow today with our #GES4SEAS #MOOC on #oceanoptimism. Coastal ecosystems and the fishing communities that depend on them are impacted globally by extreme #climate events (storms, heatwaves, etc.) and human pressures, as in these lobster and sea cucumber #fisheries

Many other large marine vertebrates have also increased in numbers thanks to protection, including #whales and sea #turtles.
All of this is in benefit of #biodiversity, but also on marine health, and human well-being
#GES4SEAS #MOOC #oceanoptimism

Studies have shown that thanks to this recovery, #kelp beds have increased and shoreline erosion has been reduced.
In this photo from Laney White @usgs-quakebot.bsky.social, you can see some sea otters resting in kelps recovered in this coast and providing multiple benefits
#GES4SEAS #MOOC #oceanoptimism

Marine #megafauna is at risk in many seas
Sea otters are iconic predators in the north Pacific, but they were heavily hunted for their fur in the 18th and 19th centuries, as @nancyknowlton.bsky.social comments in this post

#OceanOptimism: Mediterranean countries unite to protect unique deep-sea coral from fishing impacts https://europe.oceana.org/press-releases/mediterranean-countries-unite-to-protect-unique-deep-sea-coral-from-fishing-impacts/

"The measures will protect #CabliersBank, the only cold-water #CoralReef known to be growing in the #Mediterranean... Cabliers Bank is a #seamount that harbours semi-pristine species such as #DeepSea white #corals and offers shelter and nursery for several commercial stocks such as Norway #lobster and blackspot #seabream. The coral mound is over 400,000 years old."
