This article centres decolonial feminist contributions to action research, which orient us to see how the oppressive conceptual frameworks that enable sexism, gender violence, and gender inequality are fundamentally intertwined with those that enable racism, (neo)colonialism, and the pillaging and destruction of nature and planetary systems: all of which come together in the climate emergency. Given that climate change is unarguably a “threat multiplier”, if action research is to help combat the climate crisis, it must mobilise intersectional feminist, anti-racist, and decolonial frameworks. Integrating decolonial feminism with action research offers long-overdue theoretical, methodological, and practical insights. I use the acronym DF-AR to refer to existing and emerging forms of action research underpinned by decolonial feminist principles, as well as aspirational imaginaries gesturing towards decolonial feminist futures. Drawing on empirical insights from DF-AR processes embedded within an undergraduate final-year course in the UK, I consider how the experimental and micropolitical practices associated with these imaginaries can strengthen our response to the climate emergency: that is, the strategies and qualitative differences they afford.
