I searched through the forum not finding any information on how this card works.

It says: "Each player resets any of his resources dials that are higher than the amount provided by area he controls. ..."

Do I have to put the dials on the level of my current area's production and then check if there's something higher?

What happens if i conquered new areas before famine so that my dials are less then the current level of production? Do I have to increase them to the right level? Or I just reset the ones that are higher?

Let's suppose the card happens in autumn and that during spring and summer i mobilized and conquered gaining 2 new areas (all my three dials are set to the situation before new conquests: food: 5 wood:3 metal:2). The 2 recently gained areas give 1 extra food and 2 extra metal. The amount provided by area I control should be food:6 wood:3 metal:4.

What should I do during famine resolution? And what about developments?

Basically, with Famine, your dials can move DOWN, but not UP. If you've conquered new areas, such that your controlled resources are higher than your dials, nothing happens. I've you've LOST areas (or if, for whatever other reason, your dials are higher than your controlled resources) they will go down.

Basically, it's like a regular harvest, except your dials will only stay the same or move down.

In your example, your dials would stay at food;5, wood:3, ore:2.

Developments are ignored during Famine; in fact, they only do anything during the Supremacy of Harvest orders. (Although my group uses a house rule that existing developments will be collected during Bountiful Harvest, to make developments more useful and to prevent Bountiful Harvest from "hurting" a player who used a Development to gain more resources).

Thank you very much!
