Planetary boundaries discourse and narrative (Melissa Leach)

‘Planetary boundaries’ as a discourse A particular ‘regime of truth’ co-constructed through

power, knowledge and institutions

‘Accelerating human influence in the anthropocene threatening planetary boundaries’ as a powerful narrative

A storyline – with a beginning, middle and end Created by people and institutions Assigns responsibility and blame Underpins, justifies, legitimates action

Politicising planetary boundaries Matters for inclusive deliberation and debate

Leach, Raworth and Rockström 2013

Which pathways? Choosing and shaping

interlocked with power

Whose boundaries? Whose safety?

Whose goals? Sustainability and resilience of whatfor whom?

Who gains, who loses? Planetary boundaries as power grab, undermining justice and democracy?
