Foods that store well are useful for temporary settlements (whether camping trips or refugee camps) and in preparation for disasters (especially if you live in an area prone to natural disasters such as flood or earthquake).

• Vegetables that store well - root vegetables and winter squashes are key.
• Dried pulses (various beans, lentils, chick peas) - the biggest danger is that they are eaten by insect pests whose eggs are already in there. How can this be reduced? (Keep cool and extremely dry?)
• Sprouts (depending on climate) - the sprouts don't store well, but the ingredients and equipment (i.e. seeds, water, a jar and mesh) can store at least for months - even years if the seeds are stored well.
• Depending on facilities, grains or bread may be useful. Oats for example can be easily used to make nutritious porridge, though most grains are less useful.
