For urban agriculture and local food systems reducing supply chain disruptions, the most persuasive evidence would be

• A. A narrative about a single farm.
• B. Comparative data showing supply continuity during a regional disruption.
• C. An argument about taste preferences.
• D. Historical anecdotes.

Answer: (B)

Resilience in urban agriculture and local food systems is demonstrated by concrete, comparative evidence of supply continuity during disruptions. Data that quantify how much local supply keeps flowing when a regional disruption hits lets you see not just what happened in one case, but how the system performs relative to broader networks. Metrics might include days of uninterrupted availability, the share of local production meeting demand, and time to restore normal operations. This kind of evidence provides a robust view of robustness and potential scalability beyond isolated stories.

A narrative about a single farm feels compelling but lacks generalizability to the wider system. It can’t show how the broader local network would perform under broader stress. Taste preferences address consumer demand, not whether supply chains stay intact. Historical anecdotes offer context but are often situational and not systematically comparable to current conditions.
