The price of tidal power

When did it become OK to save our wildlife at the expense of everyone else’s?

There’s no joy in it but it’s got to be done. We have to press ahead with harvesting the tidal energy of the River Severn, despite the havoc it is likely to wreak on local wildlife, because these days there is no such thing as local wildlife.

When we talk about living in a globalised world, we don’t usually think about nations sharing wildlife. But we are now getting other people’s fish. Bluefin tuna and anchovies are increasingly common in British waters and no doubt we’ll be getting into fights with foreign fishing fleets about them soon. Elsewhere, species of Japanese coral are migrating northwards. A few weeks ago, Australian scientists issued a report into the ocean biodiversity in their region. Rather shockingly, their tropical fish are moving away – those that aren’t dying off in the rapidly warming water are migrating southwards, following the plankton that are being carried on currents that are rising in strength.

You won’t be surprised to hear that the blame for all this flux lies with global warming. Rising temperatures leave the inhabitants of the ocean no choice but to embrace change. Paradoxically, though, taking measures to combat global warming – such as building the Severn barrage to reduce our dependence on fossil fuels – will also force changes on the natural world. It’s now a question of whether we value our creatures more than everyone else’s.

The Severn provides Britain with a golden opportunity to exploit lunar power. The moon’s pull causes earth’s water to bulge out from the surface and the geometry of the Severn creates a bigger bulge than most. The difference between its high and low tide is the second largest in the world; only Canada’s Bay of Fundy can beat the Severn’s 14-metre pile of water.

Hold that heap of water back until just the right moment and the resulting torrent on release is a renewable source of energy. A Severn barrage would provide enough lunar electricity to power 5 per cent of Britain’s homes, equivalent to three nuclear or gas-fuelled power stations. It would also last three times longer – at least. According to projections, the barrage could operate for over a century, compared to the few decades of lifetime offered by a nuclear plant.

A cross-party group of MPs is backing a campaign for the barrage to be built and David Cameron has recently instructed the Energy Secretary, Ed Davey, to look at the proposal. It still might not take off, however. That is because, from a local perspective, it will be an environmental tragedy.

As with any hydroelectric project, holding back the water floods areas that would usually be dry. In the case of the Severn barrage, many of those areas are mudflats designated as sites of special scientific interest: feeding grounds for important bird species. It’s also worth mentioning that forcing the water through electricity-generating turbines at high pressure cannot help but hurt fish populations, too.

No pain, no gain

The consortium looking to build the barrage has come up with a design that, it claims, reduces mudflat loss by 60 per cent and operates at lower pressures, easing the toll on the Severn’s fish. Perhaps there are other mitigation efforts that can be made, such as constructing artificial mudflats at the water’s new edge. Either way, it is hard to see how we can justify holding back the barrage now. We will have to sacrifice some of our cherished natural environment.

As far as carbon-free, sustainable energy generation goes, this is the low-hanging fruit. If we don’t grab it, our continued emissions will have a similar, maybe greater, impact on biodiversity in other places. Yes, it will hurt but when did it become OK to save our wildlife at the expense of everyone else’s?

Calum Kerr on Governing the Digital Economy

With the publication of the UK Digital Strategy we’ve seen another instalment in the UK Government’s ongoing effort to emphasise its digital credentials.

As the SNP’s Digital Spokesperson, there are moves here that are clearly welcome, especially in the area of skills and a recognition of the need for large scale investment in fibre infrastructure.

But for a government that wants Britain to become the “leading country for people to use digital” it should be doing far more to lead on the field that underpins so much of a prosperous digital economy: personal data.

If you want a picture of how government should not approach personal data, just look at the Concentrix scandal.

Last year my constituency office, like countless others across the country, was inundated by cases from distressed Tax Credit claimants, who found their payments had been stopped for spurious reasons.

This scandal had its roots in the UK’s current patchwork approach to personal data. As a private contractor, Concentrix had bought data on a commercial basis and then used it to try and find undeclared partners living with claimants.

In one particularly absurd case, a woman who lived in housing provided by the Joseph Rowntree Foundation had to resort to using a foodbank during the appeals process in order to prove that she did not live with Joseph Rowntree: the Quaker philanthropist who died in 1925.

In total some 45,000 claimants were affected and 86 per cent of the resulting appeals saw the initial decision overturned.

This shows just how badly things can go wrong if the right regulatory regimes are not in place.

In part this problem is a structural one. Just as the corporate world has elevated IT to board level and is beginning to re-configure the interface between digital skills and the wider workforce, government needs to emulate practices that put technology and innovation right at the heart of the operation.

To fully leverage the benefits of tech in government and to get a world-class data regime in place, we need to establish a set of foundational values about data rights and citizenship.

Sitting on the committee of the Digital Economy Bill, I couldn’t help but notice how the elements relating to data sharing, including with private companies, were rushed through.

The lack of informed consent within the Bill will almost certainly have to be looked at again as the Government moves towards implementing the EU’s General Data Protection Regulation.

This is an example of why we need democratic oversight and an open conversation, starting from first principles, about how a citizen’s data can be accessed.

Personally, I’d like Scotland and the UK to follow the example of the Republic of Estonia, by placing transparency and the rights of the citizen at the heart of the matter, so that anyone can access the data the government holds on them with ease.

This contrasts with the mentality exposed by the Concentrix scandal: all too often people who come into contact with the state are treated as service users or customers, rather than as citizens.

This paternalistic approach needs to change.  As we begin to move towards the transformative implementation of the internet of things and 5G, trust will be paramount.

Once we have that foundation, we can start to grapple with some of the most pressing and fascinating questions that the information age presents.

We’ll need that trust if we want smart cities that make urban living sustainable using big data, if the potential of AI is to be truly tapped into and if the benefits of digital healthcare are really going to be maximised.

Clearly getting accepted ethical codes of practice in place is of immense significance, but there’s a whole lot more that government could be doing to be proactive in this space.

Last month Denmark appointed the world’s first Digital Ambassador and I think there is a compelling case for an independent Department of Technology working across all government departments.

This kind of levelling-up really needs to be seen as a necessity, because one thing that we can all agree on is that that we’ve only just scratched the surface when it comes to developing the link between government and the data driven digital economy. 

In January, Hewlett Packard Enterprise and the New Statesman convened a discussion on this topic with parliamentarians from each of the three main political parties and other experts.  This article is one of a series from three of the MPs who took part, with an  introduction from James Johns of HPE, Labour MP, Angela Eagle’s view and Conservative MP, Matt Warman’s view
