So, if Planning is considered as a way of thinking and future-oriented action based on decisions of a spatial nature taken in the present on a complex and constantly changing system. The main consequence is the impossibility of formulating an allencompassing and finalist Planning, since it is not possible to intervene on all the elements of the system, which are also in continuous evolution and transformation. Then, in a spatial context of strong uncertainty, due to the non-linear combination of different coevolutionary changes, it is not feasible to formulate a finalist image of the territory, or city, for a future time horizon. Therefore, Planning has to change its traditional budgets and accept that in a complex, diverse, evolutionary and uncertain environment its role will be very different. For that reason, Planning must accept that its fundamental objective will be the formulation of alternative solutions for each spatial problem posed, evaluating different evolutionary trajectories of the territory, in order to facilitate and improve collective decision making.EnglishopenAccessconferenceObject2831-2841
