Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
I'd already seen the DEFRA stuff. You read it, all lined up like this, and you think, wow, yeah, right. But - though there's some truth in it - it's mostly tendentious.

It turns out to be better for the environment to truck in tomatoes from Spain during the winter, for example, than to grow them in heated greenhouses in Britain.

Any winter tomatoes are grown in greenhouses, even in Spain. OK, not heated as British greenhouses would be. But is this a real choice? Are there British greenhouse tomatoes on the market in any great quantity? What's better for the environment, anyway, is not only to consume local spacewise, but also timewise, in other words eat fruit and veg in season. Winter greenhouse tomatoes are rubbish. Why buy them? (Unless occasionally if you must).

it transpires that half the food-vehicle miles associated with British food are travelled by cars driving to and from the shops. Each trip is short, but there are millions of them every day.

Why, sure. So let's truck and fly food in, and people will stop driving to and from the supermarkets?

The whole point made about cars (an SUV with one salad aboard, or people driving around buying stuff from farms, etc) ignores of course that people who choose to buy local tend to be aware of these problems. One trip to farmers' market is better than several to local producers.

Research carried out at Lincoln University in New Zealand found that producing dairy products, lamb, apples and onions in that country and shipping them to Britain used less energy overall than producing them in Britain.

It would, wouldn't it? I have my doubts.

even if flying food in from the developing world produces more emissions, that needs to be weighed against the boost to trade and development.

Righty-ho. This is where we know we're reading The Economist.

Well, and not to forget that some of the local markets might be in walking distance, or at least in easy range for the bike. These seem not to be taken into account. And maybe it is time to create more shopes were people live, so the can access them without car.

Is the DEFRA PDF available somewhere? Is there some real data in it or just sentences like above?

As for food transportation, it looks to me that orgnized home delivery tours (may be internet purchases) have the potential to be more transporation efficient than everyone round-trip'ing to the supermarket (unless it is on work-home path).

We demolished the "food mile" concept 5 months ago here. I think all you have to do is google:
If you go to google Defra and "food mile" you'll find a recent report showing that "food miles" are an inadequate indicator.
At least it worked for me back then.

First link on google is now the economist article... It's always better to put the link than rely on google :).

It's obvious that food miles is not the right unit since you need to take transporation mode and production inputs into account.

NZ study of the topic (PDF), seems to conclude that for some products it's vastly more energy-efficient to ship them to UK from NZ than to produce them in the UK.

There still is hope to eat NZ kiwis in Europe???


Now, I like this report, but would there be any interest here to do an audit of these findings? Are there elements missing, can we extend the given framework for other products?

You can always eat NZ kiwis in Europe. The question is, at what price.

Ever since the kiwi issue got flagged at the start of this year, I now feel guilty when I pick up a kiwi, being uncertain whether it's produced sustainably.

Conscious man, conscious!

What does sustainably mean? Sensu strictu, any use of fossil fuels is not sustainable, but using no fossil fuels is an absurd requirement.

In that definition, only a speck of total production is produced sustainably nowadays...

In the kiwi-case, I was thinking of an alternative kiwi produced somewhere closer to the Netherlands than NZ (which is probably Everywhere Else). That would make the description perhaps: less un-sustainable.

More sustainable, less unsustainable, more acidic, less basic, more europhilic, less eurosceptic...

But less un-sustainable does not equate to more sustainable!

saving fossil oil products for rarer uses, like lubrication, and using more renewables for transport, heating etc.

it's about having a sense of proportion, isn't it?

I didn't read in details the 117 pages PDF but it looks like that it's mainly use of fertilizer and industrial diary food (forage and cereals) that causes UK production to be more "inefficient" carbon wise (see table page 61).

So what happens if we take those out of the equation? I need to copy the spreadsheet when at home...

Too bad that they didn't take kiwis as example...

But I like the set-up, very bookkeepish. It looks superior to considering just foodmiles as metric.
