Urban development has long been associated with consumption – shopping malls, skyscrapers, tourist areas, and real estate speculation. But consumption-driven growth deepens inequality, drains resources, and turns citizens into passive consumers. As we move towards the creation of new cities and more urban sprawl, we need a more profound transformation to make cities economically, socially, environmentally, and culturally productive. Cities are designed according to the requirements and needs of their users. This is how Jane Jacobs brilliantly pointed out this shift: “Cities have the capability of providing something for everybody, only because, and only when, everybody creates them.”

Her words remind us that successful cities are not formed from the top down but from the grassroots up, through people’s active contributions, not just as recipients of welfare and housing products.

To build productive cities, we must start by putting productive economies at their center. Instead of viewing them as real estate products or prioritizing consumption, cities should invest in local production, innovation, and development centers. In doing so, cities reduce reliance on resources, stimulate jobs, and recycle value locally.

Urban design must foster productive communities – collaborative gardens, shared workshops, citizen labs, cultural gatherings – not just residential, consumer, and recreational areas.  These spaces thus transform the inhabitants into participants in the creation of their environment.
Environmentally, cities should generate life, not consume it. Lewis Mumford has observed that “the chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproduction into social creativity”.

In other words, infrastructure should not only support consumption (roads, water and sewage networks, parking spaces, and air conditioning systems).  They should produce energy, generate clean water, compost organic waste, and integrate green systems into the urban fabric.

Finally, governance must reflect production. Planning and budgeting must align and be participatory, with decision-making power channeled to communities so they become policy producers, not mere participants.

Whereas our cities are currently only seeking to attract and feed more consumption that is forced upon citizens. Productive cities strive to create material and cultural value from within.  Jacobs warned elsewhere: “There is no logic that can be superimposed on the city; people make it, and it is to them, not buildings, that we must fit our plans.”
If we pay attention to this wisdom, our urban future can evolve from passive consumption to active creativity – building a sustainable, just, income-generating, and vibrant future.
