When food systems are under strain, production methods deserve scrutiny. Vertical farming — long discussed, often dismissed — is re-examined here through the lens of technological maturation and urban land economics.

Part I focuses on the underlying logic: controlled-environment agriculture decouples certain forms of food production from traditional constraints of climate, soil, and geography. The potential implications for water use, pesticide reduction, and supply-chain resilience are significant.

Simultaneously, vertical farming faces real energy, capital, and scaling challenges. The question is not whether it will replace traditional agriculture, but where it may provide strategic advantage.

As with many emerging technologies, the most interesting opportunities may lie in targeted deployment rather than universal adoption — at least until the market matures enough to be deployed at scale.
