There are some wonderful projects happening that might surprise you.

Once we leave the extractive and large-scale framework of conventional agriculture, things start to open up a lot.

What do you mean by "agricultural land?" My land is not "agricultural land" but we might be close to filling all of our protein needs within just a few years, and in the meantime we're seeing dramatically more biodiversity and we're building the fertility of the soils.

If you're curious to explore more -

Silvopasture = growing trees on animal pasture (so: fertile soils, protein, nut/fruit crops from the trees).

Permaculture = incredibly productive and rich ecosystems

Intensive rotational grazing = moving ruminants around as they graze, which dramatically improves pasture (so eventually means much more productive land) and improves soil (which means better drought resistance and stronger ecosystem in general)

Wise use of animals and land contouring can lead to big improvement in fertility and food production in nearly every climate.

Then there's the use of biochar, thoughtful interplantings/symbiotic relationships, hydroponics... there's a lot going on and plenty of room for hope outside the factory farming and monocropping world besides cows in the Alps.
