A better city, resilient, dynamic, that is both internally and externally in harmony

The management of urban systems has become increasingly complex due to the growth of urban population within denser areas, the determination to place the individual at the heart of decision-making processes and the making of the city, as well the new sustainable development objectives assigned to cities. Grasping emerging citizen needs and understanding the evolution of cities has become as complex as it is vital, in order to make cities more sustainable, resilient and agreeable to live in. In this context, it is important to reflect on the organisational, methodological, and even technical and technological answers that can be brought to these challenges.

They are based on the «urban metabolism» concept which rests on a systemic, or even organic, approach of the city.
An alliance of virtual, physical and logistical networks enables to meet the challenges faced by the EcoCity Strategic Committee, which are:

• Perceiving the city as an ecosystem whereas so far, urban development has been viewed from a sectoral perspective. The new sustainable city challenges call for integrated answers that take into account factors such as the management of the city/nature interface, inhabitant life quality, and the interlocking of the various scales (building, efficient independent unit, neighbourhood).

• Urban services, a key element for the construction of a sustainable territory. Taking into account inhabitant diversity also requires ensuring that site accessibility is a priority for the life-quality objective. This can involved a “technologisation” of urban management. The smart city concept takes part in transforming lifestyle and governance mode. It opens up many innovation areas and new markets.

• Renewed reflection on the management of spaces and their use through new technologies and ways of making the city centred on concepts including densification, re-use of spaces, diversity and multi-purpose spaces, urban renovation, etc. Faced with the urban sprawl phenomenon and the need to reduce its energy cost, it is imperative to reflect on densification, diversity, urban renovation and multi-purpose spaces.

• The introduction of new methods enabling participatory governance and co-design with the users. They must take into account the diversification of the actors involved, with a growing convergence of the private and public spheres, citizens, private companies and public authorities.

The Strategic Committee thus acts as a motor for the cluster’s dynamics: as a «think tank» (capacity to draw new talent and make knowledge advance), a «skill counter» (capacity to guide projects and solicit key skills), and by promoting the development of on-site demonstrators.
