Biosphere Defenders Leveraging the Human Right to Healthy Environment for Transformative Change

Earth's life support systems depend on biodiversity and healthy ecosystems. Without radical transformations, staying within safe planetary boundaries becomes impossible. While the inequalities between Global North and Global South are increasingly acknowledged, the agency and rights of people often placed in the category of 'vulnerable' -women, youth, indigenous peoples and local communities- are not sufficiently recognized. This article discusses the role of biosphere defenders in the context of the 2022-2030 Kunming-Montreal Global Biodiversity Framework and the right to a healthy environment. Through dissecting judicial cases, the article investigates promising examples of ways in which biosphere defenders use the law to trigger societal change. This article finds that biosphere defenders contribute to unleashing values of responsibility by various actors, translating biocultural values of ecosystems into evidence in judicial processes impacting bureaucratic and financial systems. Supporting the work of biosphere defenders and placing the right to a sustainable environment at the heart of biodiversity and human rights law will be vital in confronting head-on the planetary crises.
