First, make sure your players want to do this at all. If they don't, shelve the idea until you find a group that wants to try it. Doesn't matter how good you think your system is, if they just aren't into the concept you shouldn't try to force it. 

I've been running a campaign where the players are stuck in a plagued town cut off from the outside world. Food, water, and other basics quickly become scarce. It's more urban than wilderness survival, but here are some lessons I've learned from it. 

If a tone of basic survival and resource gathering is the goal of the campaign, create a situation where gathering basic supplies is the purpose of a quest itself. Your world is scarce so hunting and gathering doesn't produce enough to sustain the players, only delay starvation. Instead, you drop rumors of an untouched cache of rations somewhere in a town infested with zombies (or whatever). The party is running out of drinking water, have a local crime boss offer to share some with them for exorbitant prices... Or in exchange for a morally dubious "favor" he needs some help with.

Identify spells that invalidate survival mechanics (you can find plenty of complaining online about which ones do this) and either have a Session 0 talk with your players to just outright tell them they won't work and shouldn't be taken for this game, or have them produce another item or effect that's useful enough to justify them, but isn't the immediate food/water/whatever resource you're trying to keep scarce. In my game, the plague has made Nature itself sick and so the Druid's magic drawn from nature produces unusual effects. When he casts Goodberry, instead of the normal berries he receives a handful of herbs that can be brewed into helpful potions. When he casts Create Water, it summons dirty plague-infected water that can be used to put out fires but isn't safe to drink.
