Erena Rangimarie RereOmaki Rhose, a Maori from Aotearoa (New Zealand) who has lived in Sweden for 30 years, will open the four days on planetary justice at HAU with a keynote speech. She is a guardian of traditional knowledge and a practitioner of traditional Maori medicine. She teaches Ecology-Philosophy (ekosofi) at Karlstad University and is an independent Knowledge Network Expert at the UN (Harmony with Nature). She talks about indigenous concepts of interrelations between ecologies and human actors, indigenous law and the question of the rights of nature, using the Whanganui River as a case study, which was the first to be recognized as a subject of law in 2016. The discussion will be moderated by Cecilia Oliveira, head of the research group "Democratic Governance for Ecopolitical Transformations" (EcoPol) at the RIFS (Research Institute for Sustainability at the GFZ) in Potsdam.
