In everyday life, food seems a given. In the event of collective defence , it becomes a central question of stability, order and staying power. Food supply depends on a tightly timed system of agriculture, processing, storage, retail, logistics, energy, IT and staff. It depends on every area of critical infrastructure. When individual links fail, shortages quickly arise – not just on supermarket shelves, but throughout the supply chain.
Food is one of the core civilian tasks of total defence. Responsibility for supply lies in the civilian sphere: with businesses, infrastructure operators, authorities and local authorities. Military planning can influence supply indirectly, for example by prioritising transport routes. However, it does not replace civilian structures for basic supplies.
What changes in the event of collective defence
1) Speed, intensity, multiple crises
Collective defence does not mean “a single shock”, but a phase of heightened uncertainty: disruptions to transport and energy, increased security requirements, possible cyberattacks, staff shortages and, at the same time, a growing need for reliable supply. Even a brief failure of logistics or IT can hit supply chains noticeably, because in many areas stockholding is designed for efficiency rather than reserves.
2) Competition for transport routes and capacity
When rail, road, waterways or air transport are used more heavily for military deployment and support, civilian supply chains come under pressure. This affects not only finished food, but also inputs: animal feed, seed, packaging, cold-chain materials, spare parts, fuel.
3) Information and behaviour
In supply crises, behaviour determines stability. Rumours, disinformation or panic buying can make a situation worse. Resilience therefore also means transparent communication, clear expectations and reliable local points of contact.
Where the vulnerability lies
Energy and refrigeration
Food supply is highly energy-dependent: cold stores, cold chains, production, transport and retail. Power cuts or fuel shortages have a direct impact on spoilage, availability and distribution.
Logistics and staff
Food does not arrive “by itself”. Drivers, dispatch, warehouses, transhipment, night deliveries, shift work: staff are a critical factor. In the event of collective defence, staff may also be tied up or unavailable – while demands for flexibility and replanning rise.
IT and payment systems
Ordering, inventory management, refrigeration monitoring, tills and payment systems are digital. A cyberattack or a telecoms outage can not only slow down supply but block it locally.
Packaging, water, hygiene
Processing needs water and hygiene processes. Packaging is not a by-product but a prerequisite for distribution. Shortages in these areas quickly affect availability.
What resilient food security needs in practice
1) Prioritising “must run” functions
Which businesses, warehouses, cold storage sites, transhipment points and transport lines must keep running at all costs? Which products have priority in a crisis? Resilience comes from clear priorities – not from the illusion of keeping everything stable at once.
2) Redundancy and alternative routes
- alternative supply routes and transhipment options
- backup power and fuel logistics for refrigeration and production
- emergency procedures for IT or payment system outages
- regional cooperation structures between retail, local authorities and relief organisations
Reliable, recognisable communication reduces panic and stabilises demand. This applies to businesses as well as local authorities: information on the supply situation, distribution points, opening hours, priorities and behaviour must, if necessary, also work without the internet (notices, radio, loudspeakers, local meeting points).
What this means for businesses, local authorities and households
Food industry businesses
should plan resilience along the entire chain: energy, IT, staff, logistics, refrigeration, packaging and emergency operation. What matters is not only internal plans but coordinated interfaces with logistics partners, local authorities and critical service providers.
Local authorities
need situation pictures and local points of contact: where are shortages emerging? Which vulnerable groups need support? Which places are suitable as distribution points if retail is restricted? Who communicates what?
Households
make a direct contribution to stability: anyone who stores basic supplies for a few days relieves retailers and crisis structures in the first phase. Personal preparedness is not a retreat into the private sphere, but a contribution to our collective ability to act.
Preparedness and emergency supply laws
Food: Food Security and Preparedness Act (ESVG)
The ESVG forms the legal framework for securing basic food supplies in a supply crisis and organising preparedness measures in a legally sound way. It thus addresses precisely the civilian levers that become decisive in a crisis or collective defence: prioritisation, coordination, distribution and the ability to maintain supply even when logistics, energy or staff are disrupted.
Energy: Energy Security Act (EnSiG)
The EnSiG focuses on securing the energy supply. But since food chains depend on energy at almost every stage, any measure that stabilises or prioritises energy supply indirectly affects food supply:
- Payments: tills, card payments, IT.
- Production & processing: electricity/heat for plants, hygiene, refrigeration.
- Cold chain & storage: cold stores, supermarket refrigeration, logistics warehouses.
- Transport: fuel, rail/lorry operations, transhipment.
Water: Water Supply Security Act (WasSiG)
Food depends directly on water: agriculture, processing, hygiene and cold chains need a reliable water supply. The WasSiG is relevant because water shortages quickly turn into supply crises, so prioritising food-related processes can be decisive.
Transport and logistics: Transport Security Act (VerkSiG)
Food supply depends on logistics, especially with low stock levels and energy-intensive cold chains. The VerkSiG is relevant because securing transport capacity and routes determines availability in shops and across the country.
