Try to figure out a way to get stone blocks ASAP. The upgraded buildings that you build with stone blocks do not use up resources (and will actually breed animals, since pastures normally don't use up animals by themselves.)

Best way to avoid feuds is to watch traits and send any clans with feud-causing traits out of the camp. If they want to be "warm" they will still be OK in a building such as a farm or mine. You can eventually use the tutor profession to remove bad traits but it takes a lot of parchment.

Some clans have traits that prevent other clans from feuding and/or brawling on the same tile that they are non. Gregarious? Charismatic? Maybe others? Of course, that depends upon drawing these.

Eventually, you can train an instructor who can remove a bad trait from a clan, but that is at a substantial price, and later in the game.

In the short run, if you lack the gregarious/charismatic sort, your usual line against feuders/brawlers is to send them to do work away from the camp. If they also do not like being outside, there are still jobs that involve structures. (I suppose you could suicide them by training them for outside work and moving them around in the snow without encampment... but I have never resorted to that. Not sure if there are ramificaitons.)

Resources do deplete. Less quickly if you have a structure like a farm, more quickly if you are just gathering. Only when you get to stone block structures can you avoid this. On the other hand, don't foget that it is very easy to move your camp. The game tries to shame you on any turn that you are not training a clan, but, in truth, you probably don't need to be training on every turn. So instead of using that turn to get a measley 5 treasure, use it to pack up. Next turn, move in the direction of new resources. If you re-settle with at least one movement point remaining, you will have only lost one turn of training, anyway. (And this does not cost you any of your existing structures. Farms and mines and so on will continue to function with their own areas of control. And your settled workers will continue to produce while you are moving.) Unless you are seriously hemmed in, resource depletion is not that big a threat, because you can just move to more.

As to growing things, I wonder if you just have an unusually unlucky map placement. Wheat, fruit trees, animal herds (which can be converted to meat) etc. are usually sprinkled about liberally. And there are settled professions to make them more productive. And you can research upgrades to farms. Also, if you move your settlement to a coast next to fish, that can be a great source of food.

Hope this helps!

Very helpful, thanks. I have an awesome map for mines, but very little food. I haven't moved yet because I was working the mines, but as you said the mines will continue to produce during a move (VERY good to know!!).

Interesting mix of management issues. I'm liking this game, despite all the negative comments elsewhere by other people.
