This is Sóller. A town in the north of Mallorca with a pretty church, lovely botanical gardens and a quaint tram that trundles down to the sea. But the thing it’s prob best known for is... 1/
Oranges. The orange groves, or “huertas” around Sóller (see pic) produce oranges of a particular sweetness and succulence. Louis XIV used to demand only to be served oranges from Sóller. Take it from me, they’re really juicy and lovely. 2/
But orange trees are relatively thirsty and rainfall in Mallorca is not esp frequent, so there wouldn’t be Sóller oranges without a complex system of irrigation canals originally constructed by the Moors hundreds of yrs ago. You see them all around the valley 3/
If you’re a farmer you’ll be entitled to a certain no of hours of water each week, after which it’s yr responsibility to switch a gate, diverting water onto yr neighbour downhill (pics show one of the junctions & one of those gates, which in practice is just a rock in a hole) 4/
The striking thing abt this system is it’s managed and enforced not by the Ajuntament (town hall) or a company but by the farmers themselves. If you forget to move your rock you’ll soon get a visit from an irate neighbour. The COMMUNITY manages this common resource (water) 5/
And this is not really what conventional economics implies. The whole point of the “tragedy of the commons” is that it’s a tragedy: people are doomed to deplete common resources because someone will always take advantage. But Sóller’s orange groves show that’s not quite right 6/
Indeed it turns out there are hundreds of examples of small communities coming together to manage common resources. Elinor Ostrom won a Nobel memorial prize for her work cataloguing them. Her Nobel speech is a must read on this topic [pdf]: nobelprize.org/uploads/2018/0… 7/
One of Ostrom’s examples was the orange growers around Valencia, who operate a very similar system to the one in Sóller. Here’s the map from the relevant chapter of her seminal work Governing the Commons 8/
Ostrom found that actually these community managed systems tended to be MORE efficient than those managed top down by governments or companies. This is the exact opposite of what conventional economics and the tragedy of the commons suggest. And it’s an important reminder... 9/
We often assume that if there’s the risk of a market failure the obvious solution is either top down regulation or slicing something up into parcels of privately owned land/resource. Ostrom’s work suggests there is a better bottom-up alternative 10/
Of course there are many provisos. Small community schemes to manage common resources prob won’t solve climate change or overfishing since these issues are too vast. Still it’s striking how often ppl trot out the “tragedy of the commons” w/o remembering it’s not that simple 11/
Before anyone pipes up, yes that includes me; I made a whole documentary about problems facing the oceans which talked extensively about the tragedy of the commons 12/
If you're even half interested in energy, I bet you've seen this chart. I call it The Most Hopeful Chart in the World.
The point? We're embracing renewable power MUCH faster than expected.
Hurrah!
Only problem is, this chart has an evil twin. A chart we really need to discuss
🧵
The Most Hopeful Chart in the World shows how each year the @IEA predicted that the amount of solar output around the world would plateau or rise v slowly in the following years. But instead solar output defied all expectations, rising exponentially.
That's great news.
But making solar panels is an energy-intensive exercise.
You need a lot of coal to smelt down the silicon and a lot of power to turn metallurgical silicon into polysilicon, let alone the monocrystalline boules you really need for a decent solar module (read my book for more 📖)
🚜FARMAGEDDON🌾
The story of what's REALLY going on in farming. A story far more complex than the conventional wisdom.
This isn't just (or even mainly) about inheritance tax. It's about a cascade of challenges & crises that may ultimately threaten food security.
📽️5 min primer👇
Let's begin with that big, overarching issue: food security.
For most of the past century, farmers have been encouraged to grow as much food as possible. The story here goes back to WWII and its aftermath, when the conventional wisdom was the UK needed to be more self sufficient
Encouraged by the govt, the UK's domestic food production, which before WWII had dropped to just 35% of what we ate, rose rapidly to over 60%.
Some economists say self sufficiency is overrated. But it's one of those post-war principles that stuck.
By accident as much as design.
🚗What's happening to Europe's car industry is one of the biggest stories in the world right now, & prob the biggest story of next year too.
A slow motion implosion driven by multiple factors (esp Chinese competition).
Watch my primer on what's going on👇
What makes this moment so dangerous, so destructive for legacy carmakers, is that this is a perfect storm. Three main issues: 1. The shift from conventional engines to batteries is a DISRUPTIVE innovation. The kind of thing Clay Christensen wrote about.
This is a MASSIVE deal...
Think about a combustion engine.
An assembly of HUNDREDS of pieces of metal, all perfectly honed to turn fuel into motion.
Making these things is REALLY hard. Which is why:
a) that's where most of the value/jobs are
b) other countries have struggled to compete making them
Today we learnt the no of people flowing into the UK hit an all-time high last yr: an influx we've NEVER seen before either as a total or as a share of the population.
So... why is the @ONS (and some news organisations) reporting this as a FALL in migration?!
Let's dig deeper
🧵
The ONS publishes immigration figures every six months. There's a lot of data, with plenty of provisos all over it.
But as is often the case the story gets simplified in the telling.
Consider the story the last time the data came out. This is how the chart looked 👇
And here's how most people reported the numbers: immigration was going down. Yes, from unprecedented highs - but even so. Down by 10%. A success story, as far as the then govt was concerned.
🧵SALT🧵
It's been snowing in the UK and the road gritters are out in force, begging the question:
Have you ever wondered where that grit actually COMES from?
The answer is more magical, beautiful and fascinating than you probably realised.
1/14
Because that dirty-looking salt being spread by trucks on our roads is actually the remains of an ancient ocean (actually two ancient oceans), buried deep beneath our feet.
Most of the stuff being spread in London comes from a single mine in Cheshire - at Winsford.
2/14
Here, about 20 to 40m beneath the meadows of Cheshire, is an enormous slab of halite, rock salt, the remains of an ancient inland sea a couple of hundred million years ago.
This is where most of our salt comes from.

🧵How worried should we (and @RachelReevesMP) be about the slightly nervy reaction from financial markets towards her first Budget?
Short answer: certainly a bit worried.
But perhaps not for the reasons you might expect...
Worth saying at the outset: these markets are volatile.
Trying to interpret movements in govt bonds is v tricky.
They're moved by all sorts of factors - fiscal, monetary, economic and structural - from all over the world.
So yesterday's Budget is only one of many factors here...
Even so, there has been a marked rise in UK bond yields following the Budget which is greater than what we're seeing in other markets.
This morning the UK 10 year bond yield hit the highest level in nearly a year. It's up 1.7% since yday - far more than US or German equivalents
