Answer 1

Preserving things in suger - like, for instance, by making jam - works because of osmosis ("the movement of water from where it is more concentrated to where it is less concentrated through a selectively permeable membrane", as they used to define it while I was at school, though I think they've messed with the wording again). Basically, when something is preserved in either sugar or salt, this means that any bacteria trying to grow on it are dried out because the water in them is sucked out due to the very sugary/salty surroundings.

As to whether you can use brown sugar as a preservative, I'm not sure. Theoretically it should work if, as in the above example for instance, you were to make jam, except that since brown sugar has such a rich and concentrated flavour I don't know if it would taste very nice; it might just taste burnt.
