As cities expand, so do their markets’ size and fluidity that generate agglomeration externalities. But are there any limits or conditions to urban growth?
Growing cities, both vertically and horizontally, raise the challenge of efficient supplying.
Supplying food first, to feed urban dwellers, in the context of scarce resources and local food systems.
Supplying convenience goods too, to satisfy the modern needs of customers, namely immediacy and ultra-customisation.
Last but not least, supplying energy, a key factor in Global Cities’ competitiveness as the share of energy in the value chains of both manufactured products and services keeps increasing.

Dealing with urban waste

Urban mobility is not all about time saving and increasing frequency.
Metropolitan areas have to offer efficient connections, both linking clusters to each other and integrating them into global networks and exchanges.
They also need to move towards an augmented experience of transportation.
In order to respond to rising demand for mobility and mitigate environmental impacts, developing major transport infrastructures calls for new funding vehicles.

Global Cities’ hubs at the heart of worldwide exchanges

Cities are by essence marketplaces, places for trade and for exchanges.
Campuses, clusters, business districts, Congresses and Fairs draw by definition the best talents, highly valued skills that together lead to breakthrough innovation and high added value in these special places.

Welcoming the world

Building a so-called smart city is vain if we do not lean on collective intelligence to make cities, places where everyone is able to find their place, thrive and prosper, but also to bring about urban living conditions of high quality for well-being.
Tech innovations and others make sense only when they value and foster what brings us together in town, further uniting the great variety of backgrounds who eventually make up a city.
