Downstream: what depends on it
Food system requires input Freight transport2 evidenceEstablished relation
Food system depends on Freight transport.
Mechanism
Food moves from farm to processor to store by truck, rail and ship; without freight the supply chain stops at the farm gate.

Synthetic fertilizer requires input Freight transport2 evidenceEstablished relation
Synthetic fertilizer depends on Freight transport.
Mechanism
Fertilizer is bulky and largely imported into consuming regions; rail, barge and ocean freight deliver it inside the planting window.
