Equitable and just climate action demands the integration of Indigenous perspectives in climate adaptation and mitigation. This 4-week, online course has been designed by Indigenous knowledge holders, Indigenous and non-Indigenous subject matter experts, and instructional designers. Learners will develop a broad, foundational understanding of Indigenous worldviews and perspectives on climate change, the environment, and environmental management. Learners will consider how and where Indigenous leadership can restore better practices across social and political landscapes, providing a starting point through which further learning and exploration of Indigenous perspectives, knowledge, voices, and cultural practices can emerge. Recognition of the role that colonialism has played in the climate crisis is critical. Learners (specifically, non-Indigenous learners), will leave the course with an increased capacity to understand and support Indigenous-led climate projects and practice decolonization.
