This paper develops and explores "lehae-la-rona" and its potential value in environment and sustainability discourse. It draws on African-centred concepts and critiques of dominant Eurocentric theoretical frameworks. In particular, Ani's concepts of "asili," "utamawazo" and "utamaroho" and Indigenous knowledge theory are applied to appreciate the nature of Indigenous knowledge in Lesotho. Against this backdrop, the concepts of revealed knowledge, "pono," and "pono-tebo" are applied to conceptualize "lehae-la-rona." It is argued that "lehae-la-rona" can enable a holistic conceptualization of environment and position it and the local language, Sesotho, at the centre of Education for Sustainable Development discourse to offer a more African centred worldview.
