Either a zoned area in which the land doesn't regenerate, or a protected area for nomads to place their belongings. If a protected area, then it would act as a mini tgen with possible upgrades. Otherwise, it could be similar to how the barrel works, and would have to be a certain structure, and might have to include a campfire in the vicinity. To be balanced, a nomad could only have one camp at a time, and would have to be active/return to it often for it to be not regenerated. Going with the campfire idea, to keep the camp existing maybe the fire would have to be kept alight, or else it would ''burn out'' over a week.
