Constitutionalizing Nature: Legal Innovations in the Anthropocene

Abstract

This article examines how the constitutionalization of nature is reshaping legal frameworks in response to the ecological challenges of the Anthropocene. This study employed a scientific narrative review design using a descriptive analysis method. It reviewed peer-reviewed articles, legal documents, and institutional reports published between 2019 and 2025, focusing on case studies from Ecuador, Bolivia, New Zealand, India, and Colombia. The analysis involved mapping legal innovations, evaluating procedural mechanisms, and identifying patterns in judicial and legislative reforms. The review revealed that constitutionalizing nature has led to a range of legal transformations, including granting legal personhood to rivers, embedding rights of nature in national constitutions, and developing co-governance models with indigenous communities. These innovations reflect a shift from anthropocentric to ecocentric legal reasoning and introduce new rights, duties, and enforcement mechanisms. However, the implementation of these rights faces significant institutional and interpretive challenges. Despite this, the normative power of eco-constitutionalism is influencing global legal discourse and contributing to new understandings of sovereignty and planetary governance. The constitutionalization of nature offers a transformative legal response to the ecological crises of the Anthropocene. While its success depends on effective implementation and systemic reform, it provides a compelling framework for reimagining the role of law in fostering ecological resilience and justice.
