I have a little thought too add to farming.
Where I come from there are very little water to, well water crops with, and in the old days we used something called "sjeltreko" with "vassveger"(aquaducts) too water crops with, it is basically a water shovel.
Here is a piece of an article of a neighboring town that I found:
"Lom has a long tradition of water, or rather with too little water. And although Lom has the best drinking water in Norway, the farms in Lom have struggled to get enough water for their fields. Therefore, farmers had to bring water from the snowy mountains and down to the valleys, using aqueducts (vassveg). The tool they used to spread the water over their fields is called a "Skjeltreko", and it resembles a large spoon or ladle."
Just a thought for mountain-based villages and the like.
