Maybe it's just my memory but i can't recall shortages of basic items before that, at least not on the sort of regular basis that we're now seeing.
They have always happened.
In fact if you listen to that radio piece they even say these weather events have always happened.
But nothing ever stays the same
JIT (or not quite late as I prefer to refer to it as) is now used heavily by most industries. Its great when it works, limited stock holding tying up capital, less space needed, less shrinkage due to redundancy of items etc
But when it goes wrong boy does it go wrong. Its basic assumption is it never goes wrong, and on the odd occasion it does you can simply and quickly fix the situation.
COVID showed up the weaknesses more than anything had managed up until that point. One thing that many companies suddenly had to take more into account was the benefit of a/some local supply chain.
(When Toyota invented JIT all the suppliers were within around 20 miles).
Brexit happened to show us the same lesson, but to a much more significantly lower level.
It just highlighted again, that anything that can disrupt the supply chain will have knock on effects.
Most supply chains adapted to Brexit via the most logical approach for them, insourcing, local sourcing, abandoning some channels, stock building, allowing for a longer transit time etc. Again supply chain professionals doing what they are paid to do.
I believe most businesses just sucked up the COVID disruption and most just assumed (rightly) the longer term impact would be negligible and eventually zero.
I would say that eventually we will revert to supply chains that are normal with the times of the shorter cheaper single market ones forgotten about.
We are transitioning and its easy to point out how they have changed.
IMO Brexit is well down the list in regards things into the root cause of the issue.
Its only real impact is that it made it harder to be able to react to fix the issue, and probably then only partially.
I just got back from Sainsbury's after my alidi run yesterday. the tasteless cheap toms were in stock (barely ripe again) and plenty of green peppers. any other colour they just had the organic ones at £2.50. so they had them for those fortunate enough to not worry about cash. the those struggling (or tight folk like me
) there was a lot of empty shelves
the whole turnip thing tho. perhaps it was not well presented but the idea of buying local produce which is in season is not a bad shout.... there are lots of good reasons to do that...... tomatoes/peppers and chillis tho personally are some of my guilty pleasures however and generally am prepared to use some of my carbon footprint on nice toms even out of season
no shortage of onions tho thank goodness. I love onions.
buying locally however even that is not great right now with farmers claiming their crops are rotting.
If we are that set on trying to increase the proportion of domestically produced food we really should consider the national investment needed into factory farming. The tech is all there, it can also be based far closer to where people live and working in a food factory growing food (if you get what I mean) is vastly different to growing outside with the weather impacts and the poor working conditions that brings, along with the fact its hard to get the people to do it even if you improved the conditions and wages. Simply there aren't enough people locally to do so.
