This webinar addresses the origin and definition of the term ‘Polycrisis’; the environmental, social, political and economic factors contributing to the Polycrisis; and the risks arising from the accumulation, interaction, and worsening of those contributory factors. It also considers the ways in which complexity, uncertainty and conflicting priorities are contributing to the Polycrisis, how the Polycrisis may play out in future at different scales, and what realistic mitigations and responses can be expected in the future.
