# Crop production in mountains?

Would potato- or grain-like crops be able to flourish in northern alpine regions? There's a lot to be said about the Andeans, but the have the benefit of living near the equator that other civilizations do not

Considerations:
- 8-12 thousand feet elevation
- Steep, primarily granite mountains
- Highlands climate
- 78 to 48 F in the summers
- 45 to 15 F in the winters
- 36-40 degrees North (on an Earth map)
- late medieval technology level (but not necessarily the time period)

• Hint: try to find out what crops people in Switzerland grew in the Middle Ages. It shouldn't be that hard. – AlexP Jun 30 at 19:54
• Consider Andean Agriculture: Maize, Quinoa, Amaranth, Potatoes and various other tubers. Tubers are particularly calorie-rich, so they're a very good crop for high altitudes. – Arkenstein XII Jun 30 at 20:20
• Other than the Andes are this, this and this and this.... – JBH Jul 1 at 23:11
• There's a lot of research out there you haven't availed yourself of covering regions in India, Colorado, Tibet.... This is a solved problem (a lot of the tech used today to farm above 8K feet is medieval). Start searching with (grain|vegetable) production at high altitudes and by the time you're done reading, you'll have an answer (and much more). – JBH Jul 1 at 23:13

The Incas grew many varieties of potatoes on the Andes mountains of what is now Peru. They also grew quinoa, squash, beans, and a species of corn that is different from the modern. I would expect also that any spring crop like spinach, beets, and peas would do well in a cool environment. They used terraced gardens to compensate for the lack of flat arable ground.

• Also Bolivia - the Altiplano is in both countries. The main obstacle to crop growing is not the elevation, but the fact that a lot of it is desert. – jamesqf Jun 30 at 17:46
• @jamesqf, Good point. I didn't know that -- the Altiplano part I mean – EDL Jun 30 at 20:39

Qingke

The best analogue of your nation is actually Tibet. The Tibetan plateau sits some 4.5kms above sea level, and they have crops up there which look reasonably similar to those in lower altitudes, but with some differences.

The most common crop in Tibet is something called qingke, which is a form of barley that grows particularly well in high altitudes and is both cold and drought resistant. But, they also grow wheat, rice, potatoes and the like. If you look at their farming practices in the same link, even on the side of mountains they tend to terrace their land, putting specific crops on different terraces for the season. I'm assuming that they would rotate crops between terraces for the health of the soil but I couldn't find that information in the link.

Based on my readings, barley is a common crop for high altitude and mountainous terrains, largely because of its hardiness. BUT, it's important to note that (IIRC) it has less than a third of the energy value of wheat, meaning you need to grow more of it to get the same value in terms of energy. I don't know offhand about the nutritional values but it would appear that barley related foods are a primary staple for Tibetan farmers so it certainly has to have at least some nutritional value in that regard other than energy.

Mind you, there's a key element beyond elevation, and that's location. Agriculture in Tibet and on the Altiplano is possible because they're close to the equator. Whereas in New England (where I'm from), treeline in the White Mountains goes under 4000 feet in areas. The alpine tundra's notoriously fragile -- footsteps can disrupt vegetation for many years -- and I wouldn't wager on cultivation to support just about any population in such a zone.

• Um. Tibet is about as far north as Arkansas or Andalusia. – elemtilas Jul 1 at 1:45
• ... neither of which one could call chilly regions. – Ravenswing Jul 1 at 3:32
• Point being, Tibet is not "close to the equator". – elemtilas Jul 1 at 4:35
• @elemtilas: Can't speak to Andalusia, but Arkansas lies betwee 33° and 36° 30' North, thus quite a bit closer to the equator than to the North Pole. From personal experience, it's also quite hot. – jamesqf Jul 1 at 18:17
• @jamesqf -- I don't understand your comment. My point is that Ravenswing is claiming that Tibetan agriculture is only possible because Tibet is near the equator. I'm pointing out that Tibet is, in fact, NOT NEAR THE EQUATOR AT ALL and in fact is as far away from the equator as the US midwest and southern Europe. – elemtilas Jul 1 at 23:09

It depends.

You would have the fields in the valleys, not directly on the mountain sides. In the southern parts of the mountains you could grow more crops than in the northern parts. The part of the mountains where it rains a lot are worse than the sunny parts.

I found a nice article about farming in the Alps in German here: https://www.planet-wissen.de/natur/gebirge/der_mensch_in_den_alpen/pwielandwirtschaftindenalpen100.html

It is divided into the Romanesque Alps and the Germanic Alps, here are two parts translated with DeepL:

The Romanesque mountain farmer's economy

In the High Middle Ages, agriculture perfected itself in the form of the staggered economy. The alpine areas are vertically divided into different height levels, which enables the farmers to use the terraces differently throughout the year. The yields of the individual levels must be combined in such a way that a family can make a living from them. The valleys are preferably used for growing cereals, while the higher altitudes are used for grazing livestock.

Strictly speaking, Alpine agriculture must be divided into Romanesque and Germanic regions. In Romanesque mountain farming, which can be found mainly in the Southern Alps, agriculture and dairy farming are of equal importance. The farmers use the sunny areas as arable land, while the meadows are replaced by the shady locations at higher altitudes. The arable land and fertilised meadows are privately owned, the alpine pastures and the forest are there for everyone.

[...]

Germanic mountain farming

On the humid northern edge of the Alps and in the Eastern Alps, cereal cultivation is so unfavourable that livestock farming dominates in Germanic mountain farming. The landscape of the Northern Alps therefore lacks arable terraces. The farmers use the arable land only for two to three years to cultivate cereals, after which they are green again.
