We are in an era of change, where climate, health, social and economic emergencies can no longer be ignored. Faced with the extent of these transitions, territories are in the front line. Through this paper, we will see what role territorial resilience plays in the regulation of territories in times of crisis and/or brutal shocks such as the Covid19 health crisis. As the main aim of this paper is to shed light on the factors of territorial resilience, we will then describe the different indicators that contribute to the approach to territorial resilience. Finally, we will establish the relevance of a systemic approach within this family of factors favoring territorial resilience. To do this, we will study the case of the Dunkirk territory and its systemic representation via the 'Toile' tool proposed by the Flanders-Dunkirk Region Urban Planning Agency (AGUR).
