Onde o Rio Encontra o Mar, a Justiça Flui:

A Onda de Watu como Sujeito de Direitos

Abstract

In 2024, Linhares (ES), Brazil, passed the world’s first law recognizing a wave—at the Doce River mouth (Watu, to the Krenak)—as a subject of rights. Building on community-led recovery after the 2015 Fundão dam disaster, the initiative was spearheaded by the surfing community, which spent years disconnected from the wave. By integrating biocultural values, traditional knowledge, and scientific approaches, the law is a new form of relational governance rooted in the rights of Nature. This presentation shares a practice-based case study that combines literature review and semi-structured interviews to analyze how Rights of Nature translates ancestral and local ontologies into enforceable norms; what institutional design features (e.g., a multi-stakeholder Guardians’ Committee) enable implementation; and how narrative choices, naming the Wave as kin rather than asset, counter misinformation and mobilize broader Ocean ethics. We discuss early outcomes: governance arrangements created, the preparation of a juridically oriented technical dossier (affective and scientific mapping), and challenges ahead (legal literacy, coordination across river basin and coastal regimes). Ultimately, to keep the Wave breaking, the river must remain alive, reminding us of the interdependence of ecosystems and the need for relational responsibilities across land, river, and sea.
