You can lose it for the next 40 years to a solar farm though. I'm in one England's most productive growing areas and there are some big chunks of growing land that are being given over to solar.
And it's typically land that's ALC Grade 1-3. I'm guessing from your name/comment you already know what that means. For those who don't, it ranges from the very best land that has no limitations on what can be grown on it, down to land that consistently produces moderate to high yields but of a narrower range of crops. In other words, you can grow food on it.
At planning I've repeatedly seen councillors and communities wrestling with the dilemma of needing to produce renewable energy AND needing to produce food. One council near me has now come down on the side of food production after they approved several solar projects one after another but then several more appeared. Other councils have not.
FWIW I've already got some back garden solar and am saving my pennies to cover the roof so I'm not being an anti-renewables NIMBY here. We need solar as part of our energy mix. But we also need food and I don't think we've got the balance right at the moment.
Every hectare of productive arable that goes to energy production could mean more reliance on food imports. And if overseas supplies are disrupted, countries will feed their own people before they feed the UK. Let's not kid ourselves either that all the schemes are about saving the planet: it can be far more lucrative for landowners to produce energy than to grow food. I've also seen some play down land as "only" Grade 3 in applications even though it's land that has been successfully producing tonnes of food for generations.
At least though, there's a chance the land can revert to agri use in a few decades. We can't say the same when the land becomes a housing estate!
