Is Rob Brooker coming in?

That takes us smoothly on to our second theme, which is peatlands and soils.

Is there a suggestion that, at the moment, renewables sector developers might be greenwashing by saying, “We might be displacing peat here, but we will restore it somewhere else”?

We are lucky to have two experts from the James Hutton Institute with us, so I will bring in Rob Brooker at this point.

From knowledge gained, as I have said, many years ago in the soil science department of Aberdeen University, I know that microbiology plays a huge role in this matter. The more artificial nitrogen we use, the less we rely on the microbes in the soil to fix It; in other words, microbiological and other matter in the soil is very good at allowing plants to take up nutrients, and the more artificial fertiliser we use, the less we rely on those microbes. As a result, reducing the use of artificial fertiliser has the regenerative effect of allowing these microbes to do their job again, and there is a tipping point at which the return on investment in terms of yield through the use of artificial fertiliser reduces. You do not get as big a bang for your buck, so to speak.

If that is correct, should the science be helping farmers with the decision to reduce their use of nitrogen and artificial fertilisers, given that, after a period, productivity that might have fallen will increase as the microbes in the soil start to do their job again? Again, this brings us back to the transition issue, but does part of the solution lie in knowledge transfer from you guys—the scientists—to grass-roots farmers to persuade them that doing things differently will not, in the long term, affect their bottom line and economic sustainability?

I am just seeing whether anyone is nodding. Would Pete Smith like to respond to that? [Interruption.] I beg your pardon—I had said that Rob Brooker would respond.

Do you want to comment, Pete?

Welcome back, everyone. I welcome our second panel, who will be discussing the terrestrial environment. We have with us Dr Helaina Black, honorary associate, and Professor Rob Brooker, head of ecological sciences, both at the James Hutton Institute; Professor Marc Metzger, chair in environment and society at the University of Edinburgh; and Professor Pete Smith, chair in plant and soil science at the University of Aberdeen.

I will kick off with a statement:

“For terrestrial and freshwater ecosystems, land-use change has had the largest relative negative impact on nature since 1970, followed by the direct exploitation, in particular overexploitation, of animals, plants and other organisms mainly via harvesting, logging, hunting and fishing.”

Is that level of pressure the same in Scotland as it is globally? Do those global impacts affect Scotland in different ways? I ask Professor Brooker to kick off.

We are short of time. I will hand over to Marc Metzger, who has indicated that he wishes to respond.

That is fascinating. I am about to move on, because I am at risk of hogging the whole session. You talked about changes in growth. Do warmer waters increase growth rates or, because cod are cold-water metabolising fish, if you like, do they slow them down? Do warmer waters have the opposite effect to what would be our normal thinking, which is that warm water increases growth?

What consultation did you have with egg packaging and wholesale organisations to look at the pros and cons of the instrument? Were there any adverse impacts of carrying out the inspections at a wholesaler’s premises or wherever, rather than at a border post?
