1 Jun 2018 - Oceans cover almost three quarters of the earth’s surface and billions of people globally depend on them for their livelihoods. However, plastic pollution, overfishing and maritime threats such as piracy could endanger efforts to harness the ocean’s resources for sustainable development. Dan Watson from SNTech speaks to Gitika Bhardwaj about how governments and businesses are developing solutions to these challenges.

The world is facing a number of land-based challenges, including a growing human population, and scientists recently warned that land degradation could displace at least 50 million people by 2050.

As the pressure for land-based resources increases, what is the blue economy and why is it important?

The blue economy is starting to get a lot of attention now because land issues are becoming more pressing. People are starting to look towards the large portion of the earth that’s covered by water, that previously seemed inhospitable and inaccessible, and they’re beginning to build the technology that will help us to understand it better. But how can we use the resources that are in our oceans with a more sustainable approach that we didn’t have with our land-based resources? It’s a second chance for us to do things properly. The ocean is an abundant resource and therefore has the potential to expand existing sectors as well as nurture entirely new ones – if we manage it appropriately.

The threats facing the world’s oceans have been brought into the spotlight recently in part because of programmes like the BBC’s Blue Planet. How is plastic pollution and overfishing threatening our waters?

Plastic pollution is a massive problem with over five trillion items of plastic currently littering our oceans. If you look at the scale of the problem – the amount of plastic that goes into our oceans every year which is approximately 12 million tonnes – most reports suggest it’s growing. Blue Planet, and successful campaigns in the media, have been instrumental in bringing this issue into the public consciousness and now there is innovative technology emerging.

With overfishing, the improvement of ocean data collection is helping experts to understand the scale of the problem better which can hopefully benefit government policymaking. Currently, positive steps are being taken to address overfishing in Europe, Indonesia and the US but there are still issues especially where the data available isn’t able to provide all of the answers policymakers need. For example, the effects small vessels have on fish stocks are still unclear because these catches are going largely unreported. While they are not necessarily illegal, they are not accounted for in terms of fishing quotas, therefore understanding all of the elements in order to get a full picture of what is really going on in the ocean space is important. Businesses are trying to understand the business cases around improving ocean data but there are currently few concrete examples that they are able to make to increase investment in this area – although that is starting to change.

It’s important that we develop a sustainable approach to our oceans because it will yield better resources for us in the future. We can’t afford to pollute them with materials such as plastics or by irresponsibly removing resources from the ocean space whether that’s fish, minerals or aggregates like sand. With better technology and data, we can start to address these problems by understanding their scale and then inventing appropriate solutions.

How are businesses like yours developing solutions to these issues and are these solutions scalable and affordable?

SNTech focuses on addressing the issue of unsustainable fishing practices. Globally, 1 in 10 fish caught is not the species targeted by the fisherman and this ‘by-catch’ is often thrown back into the ocean – usually dead – where it becomes waste. This translates to billions of marine organisms and billions of dollars wasted each year. Pisces, a light-emitting electronic device designed by SNTech, can be used to attract and repel different marine species based on their reaction to light, therefore lowering by-catch by up to 90 per cent and lessening the problem of overfishing.

Tackling by-catch is becoming increasingly important because of stricter fishing regulations and punishments for unsustainable fishing practices. But some of the current technology trying to reduce by-catch in commercial fishing can cost up to a million euros and weigh half a tonne. It can therefore be hard for businesses to justify investing in technology when it’s hard to recover the costs. As a result, businesses are starting to understand that they have to design scalable, affordable and sustainable technology.

IndiaSomaliaNigeria and the Seychelles are just some of the countries investing in developing a blue economy and, in April, the UK’s Environmental Audit Committee announced an inquiry into developing sustainable seas. Which governments are leading the way and which governments are falling behind?

The EU is taking a strong lead in terms of research and innovation. They have a number of high-profile research funding calls which have enabled people to start looking at these problems and design and build technology as part of the Horizon 2020 programme. There is also a lot around aquaculture, coastal tourism and ocean energy as part of their ‘Blue Growth’ strategy.

Indonesia has also gotten tough with its regulations around fishing, but it’s early days, and technology implementation and innovative management will be key to ensuring that these regulations are as effective as possible. The Indonesian government has become an example for a lot of renaissance work around fisheries, such as improved monitoring of fish catches in the supply chain and also around vessel monitoring in order to enable the government to uphold its ban on foreign vessels fishing in Indonesian waters, as well as around illegal, unregulated and unreported (IUU) fishing.

Interestingly, the Thai government are now upgrading their fisheries in response to a ‘yellow card’ issued by the EU as a result of their poor IUU record so now they are selling to European member states.

In 2017, the US also reformed its import laws in order to better understand where the fish they are buying is coming from. The state of Oregon also recently passed the first legislation mandating the use of light-emitting devices for shrimp in order to lower the bycatch of endangered eulachon fish. That’s the first state-level law that specifically says fishermen have to use a technology like our Pisces device in order to be allowed to conduct fishing operations.
