What is a plausible limitation of urban farming for resilience?

• A. It completely eliminates dependence on external food supply.
• B. It is universally scalable without policy support.
• C. It increases property values in all neighborhoods.
• D. It may not scale to feed a large population or require supportive infrastructure.

Answer: (D)

Scalability and infrastructure needs determine how much urban farming can contribute to resilience. Urban farming offers local, fresh produce and can cut some transport costs, but the amount that can be grown in cities is often limited by space, water, soil or growing media, sunlight, and labor. To truly feed a large population, you'd need extensive infrastructure—large land areas, climate-controlled facilities, irrigation and drainage systems, processing and storage, and reliable distribution networks—plus supportive policies and financing. Because of these requirements, urban farming typically complements broader food systems rather than replacing them, making its capacity to fully feed big populations a plausible limitation.
