Urban farming is growing fast

Cities will never grow their own staples. They can grow the crops that spoil fastest, and that turns out to be the point.

Urban agriculture covers three quite different things: community plots on unused land, commercial rooftop growing, and capital-intensive indoor vertical farms. They share a location and almost nothing else.

Energy decides the economics of the indoor version. Replacing sunlight with electricity is expensive, which is why the successful operations grow high-value, fast-turning crops — leafy greens, herbs, microgreens — and struggle with anything sold by the sack.

Proximity is the genuine advantage. Produce that loses quality within a day of harvest is worth more when it travels four kilometres instead of four hundred, and the waste avoided in transit is a large hidden saving.

Community growing is best judged on different terms. The yield is modest; the effects on green space, food knowledge, mental health and neighbourhood ties are the actual output and are consistently undervalued in economic assessments.

The practical policy questions are unglamorous: access to land with secure tenure, water connections, and permission to sell what is grown. Cities that solve those get urban farming without funding a single greenhouse.
