Ariel Salleh is a scholar and activist whose theoretical work re-defines humanity-nature relations in a way that integrates feminism, ecology, socialism, and indigenous struggles. Her book - Ecofeminism as Politics - subtitled nature, Marx, and the postmodern - argues an embodied materialist standpoint. A recent edited collection - Eco-Sufficiency & Global Justice shows how unconscious sex-gender assumptions distort methods and concepts in ecological economics and sustainability studies. Salleh's political ecology developed hands-on while working in Aboriginal communities; as co-convener of the Movement Against Uranium Mining; founding member of The Greens; at Earth Summit with Women's Environment & Development Organization; in local catchment campaigning; and on the Australian government's Gene Technology Ethics Committee. She has taught in Australia, Asia, and the US; has been an editor of the journal Capitalism Nature Socialism since its inception; and is currently a researcher in Political Economy at the University of Sydney.
