The ocean is the answer to future food security but we’re not using it: scientists

The vast majority of coastal countries on Earth are missing out on a valuable resource to ensure future food security, according to newly published research.

Published in the journal Nature Ecology and Evolution, the research has found that the world’s oceans contain numerous “hot spots” for marine aquaculture, or ocean-based fish farms, which could produce 15 billion tonnes of fish every year: over 100 times current seafood consumption globally.

“There are only a couple of countries that are producing the vast majority of what’s being produced right now in the oceans,” said lead author Rebecca Gentry, from UC Santa Barbara’s Bren School of Environmental Science and Management. “We show that aquaculture could actually be spread a lot more across the world, and every coastal country has this opportunity.”

However, an unwillingness by governments to seriously explore aquaculture could seriously jeopardise this.

“There is a lot of space that is suitable for aquaculture, and that is not what’s going to limit its development,” said Gentry. “It’s going to be other things such as governance and economics.”

At present, many countries choose to import much of their seafood, despite significant potential to meet their own needs.

The US, for example, imports over 90% of its fish, resulting in a trade deficit for seafood alone that tops $13bn. However, it could produce its entire domestic supply using just 0.01% of its ocean territory.

Worldwide, the story is similar: aquaculture could match the entire seafood production of every wild-caught fishery using a combined area the size of Lake Michigan: less than 1% of the total ocean surface.

And with food security under increasing threat, it is only a matter of time before countries take aquaculture seriously.

“Marine aquaculture provides a means and an opportunity to support both human livelihoods and economic growth, in addition to providing food security,” said co-author Ben Halpern, executive director of the National Center for Ecological Analysis and Synthesis (NCEAS). “It’s not a question of if aquaculture will be part of future food production but, instead, where and when. Our results help guide that trajectory.”

With such potential, it is no surprise that aquaculture is already on the increase.

“Aquaculture is expected to increase by 39% in the next decade,” said study co-author Halley Froehlich, a postdoctoral researcher at NCEAS. “Not only is this growth rate fast, but the amount of biomass aquaculture produces has already surpassed wild seafood catches and beef production.”

However, if aquaculture is going to be a core part of future food production, it needs to be managed properly, something that hasn’t always happened in the past. In the 90s, the poor management of shrimp farming in Thailand led to a boom and bust that left vast coastal areas barren.

“Like any food system, aquaculture can be done poorly; we’ve seen it,” said Froehlich. “This is really an opportunity to shape the future of food for the betterment of people and the environment.”

Scientists implant device to boost human memory

Scientists have enhanced human memory for the first time with a “memory prosthesis” brain implant. The team behind the device say it can boost performance on memory tests by up to 30%, and a similar approach may work for enhancing other brain skills, such as vision or movement.

Astronomers discover Earth-sized world 11 light years away

A planet, Ross 128 b, has been discovered in orbit around a red dwarf star just 11 light years from the Sun. The planet is 35% more massive than Earth, and it likely exists at the edge of the small, relatively faint star's habitable zone even though it is 20 times closer to its star than the Earth is to the Sun.

An algorithm can see what you've learned before going to sleep

Researcher fed the brain activity from sleeping subjects to a machine learning algorithm, and it was able to determine what the subject had learned before falling asleep. In other words, an algorithm was able to effectively ‘read’ electrical activity from sleeping brains and determine what they were memorising as a result.

Elon Musk unveils Tesla Truck and Tesla Roadster

Elon Musk has unveiled the long-anticipated 'Tesla Semi' – the company's first electric articulated lorry. The vehicle has a range of 500 miles on a single charge, and will go into production in 2019. Unexpectedly, Tesla also revealed a new Roadster, which will have a range of close to 1,000km (620 miles) on a single charge and will do 0-100mph in 4.2 seconds.

Boston Dynamics' Atlas robot can now do backflips

It's been a busy week for Boston Dynamics, first the company revealed it SpotMini robot dog was getting an upgrade, and now the company has shared a video of its Atlas humanoid robot leaping from platforms and doing a backflip. It seems like an obvious thing to say, but it's not easy to make a robot do a backflip, so how Boston Dynamics has managed it is anyone's guess.

The all new Factor Magazine is here – your guide to how today, tomorrow and beyond are being shaped

Guess who’s back, back again.

It’s been a few months, but Factor has returned with a bigger and better format, bringing the same future news and discussion, but on a platform that you can read on any device.

We’ve been working towards this for a long, long time: this is how we’ve always wanted the magazine to look, and we’re so happy to share this with you. It can be viewed on any web browser, on anything from a mobile to a monster PC, and if you’re on a desktop or laptop, click the button in the bottom right-hand corner for the ultimate shiny reading experience. A digital magazine has never looked this good. Probably.

Unfortunately that means no more iPad app, but as you can easily read the magazine from an iPad web browser, we hope you’ll agree that what we’ve gained is so much better than what’s been lost.

So anyway, here it is: the Winter 2017 issue of Factor, the first issue of the quarterly version of the magazine.

In case any of you are worrying about us publishing the magazine quarterly, trust us you don’t need to. We’ve produced the biggest issue of Factor ever, so packed with futuristic awesomeness, that we’ve had to divide it into three sections: Today, Tomorrow and Beyond.

Today deals with the futuristic present, as much of what we think of as ‘the future’ already exists today. We look at how humanoid robots are being employed as co-workers, hear from the legendary Richard Stallman about the vanishing state of privacy and discover how automation is already taking jobs. Plus, we take a light hearted look at the futuristic world of Mr Tesla, Elon Musk, and provide our festive present suggestions in a bumper futuristic gift guide.

Moving on to Tomorrow, and it’s all about the world of the next few decades, as technologies that are in development now reach fruition and seep into our everyday lives. We consider how flying cars are inching towards reality, with a look at both Lilium and the newly announced UberAir, and find out how driverless delivery may be the first true instance of the self-driving future.  Plus, we also look at the Christmas dinners of the future, because why the hell not.

Finally, in Beyond we look at the way-out future that many of us probably won’t live to see, but is supremely cool to think about. We ask leading futurists to predict what’s in store in the 22nd century – not the most positive of pictures, unfortunately – and consider what jobs will remain in a post-automation world. Plus, we look at the potential first homes of the human race beyond the solar system, and check out how asteroid mining is set to shape off-earth development.

Take a look, and if you like what you see and read, please share the magazine with your friends, or tell us what you think. This is a completely free magazine, with not an ad in sight, so it’s always good to know that it’s worth the effort.
