Danish lawmakers have agreed on a deal to plant 1 billion trees and convert 10% of farmland into forest and natural habitats in an effort to reduce fertilizer usage over the next two decades.
Yes, this is part of it, too. Usually a safe bet is a 20% contingency for planting, but you need to watch your mortality rates, obviously, as big weather events can throw that all out the window.
The current food production is approximately at 130% of the consumption, so Denmark will still have a net export.
Of course we also have imports, so the effect will be even smaller in that regard, but it's nice to know that it's fully covered in a worse case scenario.
Negatively for sure, although if they choose the worst farmland it might be by a significantly less than 10%. People can decide if the tradeoff is worth it for themselves, I guess.
The kingdom is 2.210.403km2, it's huge, 12th largest state in the world, larger than Saudi Arabia or Mexico. Most of it is Greenland though and it's going to be difficult planting forests on glaciers so I think they mean metropolitan Denmark.
