Cascades of consequences of a severe water shortage in a future climate for two areas of Quebec

Summary of the presentation

Following on the CASCADES Phase 1 project, the CASCADES Phase 2 project aims to further investigate the chain of consequences of a severe water shortage in a future climate in two integrated water management zones by watershed :

  • The Rivière du Nord integrated water management zone (Rivière du Nord watershed organization)

  • The Nicolet River integrated water management zone (COPERNIC watershed organization)


Based on a storyline approach and two workshops in the field, the project team developed location-specific fictional narratives describing a future water shortage and its consequences, incorporating specific features of the two areas being studied.
This exercise also made it possible to delve deeper into the benefits and limitations associated with the use of storylines to make the climate-related disturbances experienced during episodes of severe low water feel more real.

Learning objectives:

  • Gain knowledge of the chain of possible consequences during a severe water shortage, both in general and at the scale of the two watersheds under study

  • Understand the utility of storylines in identifying the possible consequences associated with an extreme climate event in a future climate

  • Learn lessons to facilitate local adaptation to severe water shortages
