Emergency rations

The rations are to help people survive until help arrives and are often carried while hill walking or mountaineering, because of the risk of being stranded by an accident.

Emergency rations are often carried by camping enthusiasts, especially back-pack campers, who are more likely to be far from food supplies.

Emergency rations are generally carried on the person by people on foot in case of becoming lost or separated from normal food supplies.

The makeup of emergency rations can be adjusted to suit different situations depending on which properties are the most desirable under the specific circumstances.

The energy content required for this depends on several factors, including the level of physical activity and environmental temperature.
