In ecology, local systems are more resilient. The 20-km supply chain applies this same logic to industrial and artisanal production.
In the ecology of complex systems, there is a clear principle: local systems, which are less extensive and more interconnected, are more stable over time. Reducing the distance between elements increases control, decreases energy loss, and makes the system more adaptable to the unexpected.
This is not an ideological concept, but a measurable one. Every extra step, every added kilometer, every intermediary introduces friction. Friction consumes energy, time, and quality.
Applied to production, the principle is identical. A long supply chain is a fragile system: more difficult to control, more exposed to errors, slower to correct itself. A short supply chain, on the other hand, functions like a healthy ecosystem. The elements are close, communicate with each other, and react quickly.
The 20-km supply chain was not created to tell a story, but to solve a structural problem. Less transport means fewer variables. Fewer intermediaries means greater direct responsibility. More proximity means more possibility for intervention.
In a local production system, every error is visible. Every improvement is immediate. There is no distance great enough to hide a bad decision.
GIMMI works this way because short distance allows for continuous observation, correction, and improvement. Fabrics, processing, dyeing, and tailoring are not separate phases, but parts of a single system.
As in a natural ecosystem, every element influences the others. If one part weakens, the system notices immediately. If one part improves, the benefit propagates.
In this sense, the 20-km supply chain is not an ethical choice in the abstract sense of the term. It is a functional choice. It reduces the friction of the production system and increases its overall efficiency.
Proximity is not an operational limitation. It is a condition of control. It is what allows a system to endure over time.
